PART I
ITEM 1. BUSINESS
Overview
We are a clinical-stagean ophthalmic pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye. Our strategy is to advancesuccessfully commercialize our U.S. Food and Drug Administration (“FDA”) approved product, candidates, including Rhopressa™Rhopressa® (netarsudil ophthalmic solution) 0.02% (“Rhopressa®”), and Roclatan™our advanced-stage product candidate, RocklatanTM (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% (“RocklatanTM”), previously referred to regulatory approval and commercialize these products ourselvesas RoclatanTM, if approved, in North American markets. We plan to buildthe United States. RocklatanTM has a commercial teamPrescription Drug User Fee Act (“PDUFA”) goal date of approximately 100 sales representatives to target approximately 10,000 high prescribing eye-care professionals throughout North America.March 14, 2019. We are also directing our own clinical trials to gain developing Rhopressa® and RocklatanTM (named Rhokiinsa® and RoclandaTM, respectively, in Europe) forregulatory approval in Europe and are preparingJapan and expect to either use a contract research organization, or otherwise partner, to conduct the necessary trials to gain approval in Japan. For commercialization outside of North America, we may potentially commercialize ourselveson our own in Europe and likely partner for commercialization of their equivalents in Japan, if approved. We are also focused on furthering the development of our preclinical molecules and technologies focused on retinal diseases and expect to explore partnership opportunities through collaborationhave two preclinical implants, AR-1105 and licensing arrangementsAR-13503, commence clinical trials in Europe and Japan. We expect to finalize our European commercialization strategy by the end of 2016. We are enhancing our longer-term commercial potential by identifying and advancing additional product candidates, including through our internal discovery efforts, research collaborations, potential in-licensing or acquisitions of additional ophthalmic products or technologies or product candidates that would complement our current product portfolio.
We completed our IPO in October 2013 which raised net proceeds of approximately $68.3 million. Since our IPO we have raised additional net proceeds of approximately $122.9 million through the sale and issuance of the 2014 Convertible Notes in September 2014, and approximately $50.5 million through at-the-market sales during 2015. Our senior leadership team has extensive experience in the ophthalmology market and has overseen the development and commercialization of several successful ophthalmic products at major pharmaceutical companies. If our products are approved and2019. Further, we are commercially successful, we believe Aerie could becomescreening our owned library of Rho kinase (“ROCK”) inhibitors for indications beyond glaucoma.
Rhopressa® is a major ophthalmic pharmaceutical company.
Our two advanced stage product candidates areonce-daily eye drop designed to lowerreduce elevated intraocular pressure or IOP,(“IOP”) in patients with open-angle glaucoma andor ocular hypertension. Both product candidates are taken once-daily and have shownThe active ingredient in preclinical and clinical trials to be effective in lowering IOP, with novel mechanisms of action, or MOAs, and a positive safety profile. GlaucomaRhopressa®, netarsudil, is one of the largest segments in the global ophthalmic market. In 2014, branded and generic glaucoma product sales exceeded $4.7 billion in the United States, Europe and Japan in aggregate, according to IMS. Prescription volume for glaucoma products in the United States alone exceeded 33 million in 2014 and is expected to grow, driven in large part by the aging population.
Our lead product candidate is once-daily Rhopressa™.an Aerie-owned ROCK inhibitor. We successfully completed our second Phase 3 registration trial for Rhopressa™, named “Rocket 2,” in September 2015, which will be the pivotal trial for a New Drug Application, or NDA, filing with the U.S. Food and Drug Administration, or FDA,believe that we expect to submit in the third quarter of 2016. The primary clinical efficacy endpoint was to demonstrate non-inferiority of IOP lowering of Rhopressa™ compared to timolol in a 90-day efficacy period. The final primary baseline IOP ranges for Rocket 2 were above 20 mmHg (millimeters of mercury) to below 25 mmHg. In addition to successfully achieving non-inferiority to timolol at this endpoint range, the recently reported topline 12-month safety data from Rocket 2 confirmed a positive safety profile for the drug and demonstrated a consistent IOP lowering effect throughout the 12-month period at the specified timepoint.

As background, the final primary endpoint range for Rocket 2 was updated from the original trial design, which included baseline IOPs of up to 27 mmHg. This change in endpoint range was made while Rocket 2 was in progress and prior to the database being locked, and was performed with FDA agreement. The reason for the change was the failure of our first Phase 3 registration trial for Rhopressa™, named “Rocket 1.” This 90-day efficacy trial did not meet its primary clinical efficacy endpoint of demonstrating non-inferiority of IOP lowering of Rhopressa™ compared to timolol at its primary range of above 20 mmHg to below 27 mmHg, which we reported in April 2015 (while Rocket 2 was already underway). Rocket 1 was successful at its pre-specified secondary endpoint range of above 20 mmHg and below 24 mmHg, and it was agreed by the FDA that Rocket 1, because of its success in meeting the secondary endpoint range, could be used as supportive to Rocket 2 for the upcoming NDA filing.

We are also conducting a third Phase 3 registration trial for Rhopressa™, named “Rocket 3,” in Canada, which is a supplementary 12-month safety-only trial and is not required for NDA filing purposes. In addition, we are conducting a fourth Phase 3 registration trial for Rhopressa™, named “Rocket 4,” in the U.S., which is designed to generate the six-month safety data that will be needed for European approval purposes, and is also not required for NDA filing purposes. We expect to report the topline 90-day interim efficacy data for Rocket 4 in the fourth quarter of Rhopressa2016.®

We are developing Rhopressa™ as represents the first of a new drug class of compounds that is designed to lower IOP in patients through novel MOAs. We believe that, if approved, Rhopressa™ will represent the first new MOAs for loweringreducing IOP in patients with glaucoma in over 20 years. Based on clinical dataEarly indications point to date, we expect that Rhopressa™, if approved, will compete withhealthcare professionals prescribing Rhopressa® as a concomitant therapy to prostaglandins or non-PGA (prostaglandin analog) medications when additional IOP reduction is desired. We believe Rhopressa® is primarily competing with other non-PGA products, as a preferred adjunctive therapy to PGAs, due to its IOP-loweringtargeting of the diseased trabecular meshwork (“TM”), its demonstrated ability to reduce IOP at consistent levels across tested baselines, withits preferred once-daily dosing relative to other currently marketed non-PGA products and its potential synergistic effect with PGA products.safety profile. Adjunctive therapies currently represent approximatelynearly one-half of the entire glaucoma therapyprescription market in the United States. In addition, if approved, weStates, according to IQVIA. We believe that Rhopressa™Rhopressa® may also become a preferred therapy where PGAs are contraindicated, for patients who do not respond to PGAs for patients who have lower IOPs but nevertheless present with glaucomatous damage to the optic nerve, which is commonly referred to as “low-tension” or “normal tension” glaucoma, as well asand for patients who choose to avoid the cosmetic issues associated with PGA products.

We launched Rhopressa® in the United States at the end of April 2018. Rhopressa® is now being sold to national and regional U.S. pharmaceutical distributors, and patients have access to Rhopressa® through pharmacies across the United States. In the glaucoma market in the United States, approximately half of the dispensed volumes are covered under commercial plans and half under Medicare Part D. We have obtained formulary coverage for Rhopressa® for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans. We expect Medicare Part D Tier 2 equivalent coverage to increase to over 70% by the end of the first quarter of 2019.
Our secondadvanced-stage product candidate, is once-daily Roclatan™. Roclatan™RocklatanTM, is a once-daily fixed-dose combination of Rhopressa™Rhopressa® and latanoprost, which is the most commonly prescribed drug for the treatment of patients with open-angle glaucoma. We currently have one Phase 3 registration trial for Roclatan™ in process with a second about to start, after having successfully completed a Phase 2bbelieve, based on our clinical trial for patients with open-angle glaucoma and ocular hypertension in June 2014. In the the Phase 2b clinical trial, Roclatan™ achieved its primary efficacy endpoint on day 29 and statistical superiority over individual components at all timepoints. We believe Roclatan™data, that RocklatanTM has the potential to provide a greater IOP-loweringIOP-reducing effect than any currently approvedmarketed glaucoma product.medication. Therefore, we believe that Roclatan™RocklatanTM, if approved and formulary coverage is obtained, could compete with both PGA and non-PGA therapies and become the product of choice for patients requiring maximal IOP lowering.reduction, including those with higher IOPs and those who present with significant disease progression despite using currently available therapies.
TheWe submitted a New Drug Application (“NDA”) for RocklatanTM to the FDA in May 2018 under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act (the “FDCA”), which provides for an abbreviated approval pathway, since RocklatanTM is a fixed dose combination of two FDA-approved drugs in the United States. In July 2018, we announced that the NDA was accepted for review by the FDA and the PDUFA goal date was set for March 14, 2019.
We have a commercial team that includes approximately 100 sales representatives targeting approximately 14,000 high-prescribing eye-care professionals throughout the United States. This sales force is responsible for sales of Rhopressa®, and will also be responsible for sales of RocklatanTM, if approved.
Our strategy also includes developing our business outside the United States, including obtaining regulatory approval in Europe and Japan on our own for Rhopressa® and RocklatanTM. If we obtain regulatory approval, we currently expect to commercialize Rhopressa® and RocklatanTM in Europe on our own, and likely partner for commercialization of their equivalents in Japan. If

approved, we expect that Rhopressa® and RocklatanTM will be marketed under the names Rhokiinsa® and RoclandaTM, respectively, in Europe. To optimize the commercial opportunity, we expect to launch RoclandaTM before Rhokiinsa® in Europe, if approved, as the European market is oriented more toward fixed-dose combination products. We are continuing to expand our presence in Europe and are actively participating in European ophthalmology conferences and forums. We now have over 60 employees in Europe that manage the build-out and operation of our manufacturing plant in Ireland, discussed below, as well our Phase 3 clinical trial for RocklatanTM, which is ongoing in several European countries. We are also building our clinical, medical affairs and commercial teams in Europe. In Japan, we announced the opening of our office in Tokyo and the hiring of key leadership positions to help execute our strategy in that market.
With respect to regulatory approvals of Rhopressa® in jurisdictions outside the United States, in October 2018, we announced that the European Medicines Agency (“EMA”) accepted for review our marketing authorisation application (“MAA”) for Rhokiinsa®. Additionally, we completed a Phase 1 clinical trial and a successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which were designed to support meeting the requirements of Japan’s Pharmaceuticals and Medical Devices Agency (“PMDA”) for potential regulatory submission of Rhopressa® in Japan. We are also planning to initiate a Phase 2 clinical trial on Japanese patients in Japan by the end of the first quarter of 2019 to support subsequent Phase 3 registration trial for Roclatan™, named “Mercury 1,” commencedtrials that are also expected to be conducted in September 2015. We expectJapan under our direction.
With respect to commence our secondRocklatanTM in jurisdictions outside the United States, we have completed two Phase 3 registration trial for Roclatan™ ,trials named “Mercury 2,” in March 2016. Mercury 1 is a 12-month safety trial which includes a 90-day interim efficacy readout and Mercury 2 is a 90-day efficacy trial. Both trials are designed to demonstrate superiority of Roclatan™ to each of its components, similar to the successful Phase 2b trial. If both Mercury 1 and Mercury 2, are successful, we expect to file an NDA for Roclatan™in the second half of 2017, approximately one year after the NDA filing for Rhopressa™.
We believe our clinical plans for both Rhopressa™and Roclatan™ are already in place to satisfy European regulatory requirements. In addition to Rocket 1 and Rocket 2, the Rocket 4 trial is designed to provide adequate six month safety data for RhopressaTM to meet European requirements. Based on our Rhopressa™ clinical plan, we expect to file for regulatory approval in Europe by mid-2017. Whilediscussed further below. Both Mercury 1 and Mercury 2 will be used for European approval of RoclandaTM. We also initiated a Phase 3 registration trial for Roclatan™RoclandaTM, named Mercury 3, in Europe during the third quarter of 2017. Mercury 3, a six-month efficacy and safety trial, is designed to compare RoclandaTM to Ganfort®, a fixed-dose combination product marketed in Europe of bimatoprost, a PGA, and timolol, a beta blocker. If successful, Mercury 3 is expected to improve our commercialization prospects in Europe. We currently expect to read out topline 90-day efficacy data for the Mercury 3 trial in 2019. We expect to submit an MAA with the EMA in early 2020 for RoclandaTM, if the EMA has approved Rhokiinsa® by such time.
In January 2017, we commenced establishment of our own manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, which is expected to produce commercial supplies of Rhopressa® and, if approved, RocklatanTM, Rhokiinsa® and RoclandaTM. Commercial supply from the plant is expected to be available in early 2020. Our current contract manufacturer produces commercial supply of Rhopressa® and started to manufacture RocklatanTM in 2018 in anticipation of potential FDA approval and commercial launch in 2019. We are also in the process of adding an additional active pharmaceutical ingredient (“API”) contract manufacturer and an additional Rhopressa® drug product contract manufacturer, both of which are expected to supply commercial materials in the first half of 2019. We expect to continue to use product sourced from our contract manufacturers when the Ireland plant is operational.
We also seek to enhance our longer-term commercial potential by identifying and advancing additional product candidates through our internal discovery efforts, our entry into potential research collaborations or in-licensing arrangements or our acquisition of additional ophthalmic products or technologies or product candidates that complement our current product portfolio. Our collaboration with DSM, a global science-based company headquartered in the Netherlands, provides access to their bio-erodible polymer technology, and our acquisition of assets from Envisia Therapeutics Inc. (“Envisia”), which includes the rights to use PRINT® manufacturing technology for ophthalmology, are designed to advance our progress in developing potential future sustained-release implant product candidates to treat retinal diseases. In August 2018, we announced the expansion of our collaboration with DSM to provide for (i) a worldwide exclusive license for all ophthalmic indications to DSM’s polyesteramide polymer technology, (ii) continuation of the collaborative research initiatives through the end of 2020, including the transfer of DSM’s formulation technology to Aerie during that time and (iii) access to a preclinical latanoprost implant.
Aided by these technologies, we are developing two preclinical sustained-release implants focused on retinal diseases. AR-13503, for which we expect to submit an Investigational New Drug application (“IND”) in the first quarter of 2019, is an Aerie-owned ROCK and Protein kinase C inhibitor with potential in the treatment of diabetic macular edema (“DME”), wet age-related macular degeneration (age-related macular degeneration, “AMD”) and related diseases of the retina. AR-13503 has shown lesion size decreases in an in vivo preclinical model of wet AMD at levels similar to the current market-leading wet AMD anti-vascular endothelial growth factor (vascular endothelial growth factor, “VEGF”) product. When used preclinically in combination with the market leading anti-VEGF product, AR-13503 produced greater lesion size reduction than the anti-VEGF product alone in a model of proliferative diabetic retinopathy (diabetic retinopathy, “DR”). Additionally, through the Envisia asset acquisition, we are developing AR-1105, a preclinical dexamethasone steroid implant. The IND for AR-1105 was submitted in December 2018, and in January 2019, we announced that the FDA reviewed the IND and it is now in effect, allowing Aerie to initiate human studies in the treatment of macular edema due to RVO. We expect to initiate a Phase 2 clinical study later in the first quarter of 2019.

Further, we are evaluating our owned library of ROCK inhibitors for potential indications beyond ophthalmology. There are several disease categories where ROCK inhibitors have demonstrated benefits both preclinically and clinically in past third-party studies and trials, and we are initially focused on exploring potential opportunities for our molecules in pulmonary health, dermatology and cancer. We are in the initial stages of our work on these applications.
We own the worldwide rights to all indications for Rhopressa® and RocklatanTM.We have patent protection for Rhopressa® and RocklatanTM in the United States through early 2034 and internationally, through dates ranging from 2030 to 2037. Our intellectual property portfolio contains patents and pending patent applications related to composition of matter, pharmaceutical compositions, methods of use and synthetic methods. Furthermore, we have patent protection for AR-13503 in the United States and internationally, which extends to 2030. We have also filed for patent protection for AR-1105 in the United States and internationally.
Our Strategy
Our goal is to become a leader in the discovery, development and commercialization of first-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye. We believe Rhopressa® and RocklatanTM have the potential to address many of the unmet medical needs in the glaucoma market, and preclinical implants AR-1105 and AR-13503 have the potential to address unmet needs in the retinal disease market. Key elements of our strategy are to:
Successfully commercialize Rhopressa® in North America. We own worldwide rights to all indications for Rhopressa® and we intend to retain our commercialization rights in North American markets. We launched Rhopressa® in the United States at the end of April 2018. Our sales organization is targeting approximately 14,000 high prescribing eye-care professionals throughout the United States. We have already obtained formulary coverage for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans. We expect Medicare Part D Tier 2 equivalent coverage to increase to over 70% by the end of the first quarter of 2019.
Obtain FDA approval of RocklatanTM and manage a successful commercial launch, if approved. RocklatanTM is a fixed dose combination of two FDA-approved drugs in the United States. In July 2018, we announced that our NDA was accepted for review by the FDA and the PDUFA goal date was set for March 14, 2019, which represents a ten-month review. If approved, our existing sales force will be responsible for sales in the United States of RocklatanTM in addition to Rhopressa®. We own the worldwide rights to all indications for RocklatanTM.
Advance the development of Rhopressa® and RocklatanTM in jurisdictions outside the United States to regulatory approval and commercialize on our own in Europe while likely securing a commercialization partner in Japan. Our strategy includes developing our business in jurisdictions outside of the United States, including obtaining regulatory approval on our own in Europe and Japan for Rhopressa® and RocklatanTM. If we obtain regulatory approval, we currently expect to commercialize Rhopressa® and RocklatanTM ourselves in Europe, which will be marketed as Rhokiinsa® and RoclandaTM, respectively. We will likely partner for commercialization of their equivalents in Japan, if approved. With respect to regulatory approvals for Rhopressa®, in October 2018, we announced that the EMA accepted for review our MAA for Rhokiinsa®. Additionally, we completed a Phase 1 clinical trial and a successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which were designed to support meeting the requirements of Japan’s PMDA for potential regulatory submission of Rhopressa® in Japan. We are also preparing to initiate a Phase 2 clinical trial on Japanese patients in Japan by the end of the first quarter of 2019 to support subsequent Phase 3 registration trials that are also expected to be conducted in Japan under our direction.
With respect to RocklatanTM, we commenced the Mercury 3 Phase 3 clinical trial in Europe during the third quarter of 2017, which is designed to compare RoclandaTM to Ganfort®, a fixed-dose combination product marketed in Europe of bimatoprost, a PGA, and timolol, a beta blocker. If successful, Mercury 3 is expected to improve our commercialization prospects in Europe. We currently expect to read out topline 90-day efficacy data for the trial in 2019. Since RoclandaTM is a fixed-dose combination product that includes Rhokiinsa®, we plan to submit an MAA for RoclandaTM with the EMA if and when Rhokiinsa® is approved by the EMA. We expect to submit the MAA for RoclandaTM in early 2020, if the EMA has approved Rhokiinsa® by such time.
Continue to leverage and strengthen our intellectual property portfolio. We believe we have a strong intellectual property position relating to Rhopressa® and RocklatanTM. Our intellectual property portfolio contains U.S. and foreign patents and pending U.S. and foreign patent applications related to composition of matter, pharmaceutical compositions, methods of use and synthetic methods. We have patent protection for Rhopressa® and RocklatanTM in the United States, which extends through early 2034, and internationally, through dates ranging from 2030 to 2037. Furthermore, we have patent protection for AR-13503 in the United States and internationally, which extends to 2030. We have also filed for patent protection for AR-1105

in the United States and internationally. We will also continue to evaluate our owned library of ROCK inhibitors for novel uses and applications and intend to seek intellectual property protection for any such developments.
Expand our product candidate portfolio and pipeline through internal discovery efforts, research collaboration arrangements and in-licensing or acquisitions of additional product candidates, products or technologies. We continue to seek to discover and develop new compounds in our research laboratories, and our scientific staff are currently focused on evaluating our portfolio of owned ROCK inhibitors for additional indications within and beyond ophthalmology. In addition, we may enter into additional research collaborations or license arrangements or complete additional acquisitions to broaden our presence in ophthalmology, as we continually explore and discuss potential additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas. Through business development activities, we have acquired the worldwide ophthalmic rights to a bio-erodible polymer technology from DSM, and PRINT® implant manufacturing technology from Envisia. With these, we have created a unique sustained-release ophthalmology platform that, initially, allows for the progression of our sustained-release retinal implant program. Using this technology, we are currently developing two preclinical sustained-release implants focused on retinal diseases, AR-1105 and AR-13503, for which we expect to commence clinical trials in 2019. We believe there is a need in the current retinal diseases treatment paradigm for new treatment pathways and less frequent injections. The U.S. retinal disease market was approximately $5 billion in 2017.
Our Product, Product Candidate and Pipeline
Rhopressa®, our FDA-approved product, has demonstrated that it reduces IOP through ROCK inhibition, its mechanism of action (“MOA”), by which Rhopressa® increases the outflow of aqueous humor through the TM, which accounts for approximately 80% of fluid drainage from the healthy eye. Our advanced-stage product candidate is once-daily RocklatanTM, a fixed-dose combination of Rhopressa® and latanoprost, which reduces IOP through the same MOA as Rhopressa® and through a second MOA, utilizing the ability of latanoprost to increase the outflow of aqueous humor through the uveoscleral pathway, the eye’s secondary drain. Our preclinical pipeline includes AR-13503, a ROCK and Protein kinase C inhibitor being developed for DME, wet AMD and related diseases of the retina, and AR-1105, a dexamethasone steroid implant being developed for macular edema due to RVO. Both of these products are being designed as miniaturized bio-erodible implants that would be injected intravitreally every six months and both are expected to commence clinical trials in 2019.
We discovered and developed Rhopressa®, RocklatanTM and AR-13503 internally through a rational drug design approach that coupled medicinal chemistry with high content screening of compounds in proprietary cell-based assays. We selected and formulated Rhopressa® and RocklatanTM for preclinical in vivo testing following a detailed characterization of over 3,000 synthesized ROCK inhibitors, a number that has since grown to approximately 4,000. We continue to seek to discover and develop new compounds in our research laboratories, and our scientific staff with expertise in medicinal chemistry, analytical chemistry, biochemistry, cell biology, pharmacology and pharmaceutical science are currently focused on evaluating our portfolio of owned ROCK inhibitors for additional indications within and beyond ophthalmology.

Rhopressa®
Rhopressa® is the first of a new class of glaucoma drug products that was discovered by our scientists. It was approved by the FDA on December 18, 2017 for the reduction of elevated IOP in patients with open-angle glaucoma or ocular hypertension and is not yet approved outside of the United States. Our key target markets outside the United States include Europe and Japan.
The active ingredient in Rhopressa® is netarsudil, a ROCK inhibitor. ROCK is a protein kinase, which is an enzyme that modifies other proteins by chemically adding phosphate groups to them. Specifically, ROCK regulates actin and myosin, which are proteins that are responsible for cellular contraction. ROCK activity also promotes the production of extracellular matrix proteins. ROCK inhibitors block TM cell contraction and reduce the production of extracellular matrix, thereby improving TM fluid outflow and consequently reducing IOP.
Rhopressa® is competing primarily in the adjunctive therapy market, which represents approximately one-half of the U.S. glaucoma prescription market and totaled approximately 37 million prescriptions in 2017 according to IQVIA. Initial indications point to healthcare professionals prescribing Rhopressa® as a concomitant therapy to prostaglandins or non-PGA medications when additional IOP reduction is desired. We believe Rhopressa® is primarily competing with other non-PGA products, due to its targeting of the diseased TM, its demonstrated ability to reduce IOP at consistent levels across tested baselines, its preferred once-daily dosing relative to other currently marketed non-PGA products and its safety profile. Currently marketed therapies that are used adjunctively to PGAs are older generation products that are generally dosed between two and three times a day, have MOA(s) focused on reducing fluid production, often have lower efficacy levels and have systemic side effects. We believe that Rhopressa® may also become a preferred therapy where PGAs are contraindicated, for patients who do not respond to PGAs and for patients who choose to avoid the cosmetic issues associated with PGA products.
Rhopressa®in the United States
Rhopressa® received FDA approval on December 18, 2017 and we launched Rhopressa® in the United States at the end of April 2018. Rhopressa® is now being sold to national and regional U.S. pharmaceutical distributors, and patients have access to Rhopressa® through pharmacies across the United States. We have obtained formulary coverage for Rhopressa® for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans. We expect Medicare Part D Tier 2 equivalent coverage to increase to over 70% by the end of the first quarter of 2019.

Rhopressa®Outside of the United States
On October 9, 2018, we announced that the EMA accepted our MAA for Rhokiinsa® for review.
Additionally, we completed a Phase 1 clinical trial and a successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which were designed to support meeting the requirements of Japan’s PMDA for potential regulatory submission of Rhopressa® in Japan.
The primary objectives of the study were to evaluate (1) the ocular hypotensive activity of two concentrations of netarsudil ophthalmic solution (0.02% and 0.04%) relative to placebo over a 28-day period, for a total of three arms all dosed in the evening, and (2) the ocular and systemic safety of netarsudil ophthalmic solution relative to placebo over the same 28-day period. The results demonstrated that netarsudil ophthalmic solution 0.02% reduced mean diurnal IOP by a range of 5.0 to 5.3 millimeters of mercury (“mmHg”) for subjects with an average baseline IOP of 18.3 mmHg. The netarsudil ophthalmic solution 0.04% arm reduced IOP by a range of 5.2 mmHg to 6.6 mmHg for subjects with an average baseline IOP of 20.2 mmHg. The placebo arm reduced IOP by a range of 2.0 to 2.5 mmHg for subjects with an average baseline pressure of 19.6 mmHg. Both netarsudil arms showed higher levels of IOP reduction as compared to placebo to a statistically significant degree at day 28. The safety findings were consistent with our previous netarsudil trials.
We are also planning to initiate a Phase 2 clinical trial on Japanese patients in Japan by the end of the first quarter of 2019 to support subsequent Phase 3 registration trials that are also expected to be conducted in Japan under our direction.
Rhopressa® Additional Research
We have performed additional research on the 24-hour IOP-reduction characteristics of Rhopressa®. In a 24-hour pilot study of 12 patients designed to compare the efficacy of Rhopressa® to that of placebo, Rhopressa® demonstrated consistent levels of IOP reduction during nocturnal and diurnal periods, to a meaningfully greater extent than placebo. This is potentially a further differentiating feature of Rhopressa® when considering that currently marketed products have demonstrated little or no efficacy at night, and eye pressure is typically highest when patients are asleep.
We also plan to initiateperform additional research on the potential benefits of Rhopressa® on normal tension glaucoma, pseudoexfoliative glaucoma and corneal healing, among others.
RocklatanTM
Our advanced-stage product candidate is once-daily RocklatanTM, a fixed-dose combination of Rhopressa® and latanoprost. We believe, based on our Phase 3 clinical trial data, that RocklatanTM, if approved, may provide a greater IOP-reducing effect than any currently marketed glaucoma medication. Therefore, we believe that RocklatanTM, if approved and formulary coverage is obtained, could compete with both PGA and non-PGA therapies for patients requiring maximal IOP reduction, including those with higher IOPs and those who present with significant disease progression despite use of currently available therapies.
RocklatanTM in the United States
We submitted an NDA for RocklatanTM to the FDA in May 2018 under Section 505(b)(2) of the FDCA, which provides for an abbreviated approval pathway, since RocklatanTM is a fixed dose combination of two FDA-approved drugs in the United States. In July 2018, we announced that the NDA was accepted for review by the FDA and the PDUFA goal date was set for March 14, 2019, which represents a ten-month review.
We have completed two Phase 3 registration trials for RocklatanTM, named Mercury 1 and Mercury 2, each discussed further below.The Mercury 2 trial design was identical to that of Mercury 1, except that Mercury 2 was a 90-day trial without the additional nine-month safety extension included in Mercury 1. The safety results for RocklatanTM showed no treatment-related serious adverse events and minimal evidence of treatment-related systemic effects. There were no new adverse events that developed over the 12-month period relative to the 90-day results, and there were no drug-related serious or systemic adverse events. Both Mercury 1 and Mercury 2 achieved their 90-day primary efficacy endpoints of demonstrating statistical superiority of RocklatanTM over each of its components at all measured time points in patients with maximum baseline IOPs of above 20 mmHg to below 36 mmHg.
RocklatanTM Outside of the United States
Mercury 1 and Mercury 2 will be used for European approval of RoclandaTM. We also initiated a third Phase 3 registration trial for Roclatan™RoclandaTM, named “MercuryMercury 3, in Europe induring the first halfthird quarter of 2017. Mercury 3, will bea six-month efficacy and safety trial,

If successful, shouldMercury 3 is expected to improve our commercialization prospects in Europe. Patients are being evaluated with maximum baseline IOPs ranging from above 20 mmHg to below 36 mmHg. We currently expect to read out topline 90-day efficacy data for the Mercury 3 trial in 2019. Since RoclandaTM is a fixed-dose combination product that region.includes Rhokiinsa®, we plan to submit an MAA for RoclandaTM with the EMA if and when Rhokiinsa® is approved by the EMA. We expect to submit the MAA for RoclandaTM in early 2020, if the EMA has approved Rhokiinsa® by such time.
Our stated objective isRocklatanTM Phase 3 Trial Data to buildDate
We have completed two Phase 3 registration trials for RocklatanTM, as discussed above. Mercury 1 was a major ophthalmic pharmaceutical company.12-month safety trial with a 90-day efficacy readout. Mercury 1 achieved its primary efficacy endpoint of demonstrating statistical superiority of RocklatanTM to each of its components, including Rhopressa® and latanoprost, in patients with maximum baseline IOPs of above 20 mmHg to below 36 mmHg. In the 90-day efficacy results, the IOP-reducing effect of RocklatanTM exceeded that of monotherapy with latanoprost in a range of 1.3 mmHg to 2.5 mmHg and Rhopressa® in a range of 1.8 mmHg to 3.0 mmHg. In July 2017, we announced the 12-month safety results of the Mercury 1 study, which were consistent with those observed for the 90-day efficacy period, noting the safety results for RocklatanTM showed no treatment-related serious adverse events and minimal evidence of treatment-related systemic effects. The most common RocklatanTM adverse event was conjunctival hyperemia, which was observed in approximately 60% of patients, which was scored as mild in approximately 70% of affected patients. Other ocular adverse events reported in approximately 5% to 18% of patients in the RocklatanTM group included corneal verticillata, conjunctival hemorrhage, eye pruritus, increased lacrimation, reduced visual acuity, blepharitis and punctate keratitis.
The graph below represents the responder analysis from the Mercury 1 90-day efficacy results, which shows the percentage of patients for whom IOP was reduced to 18 mmHg or lower, comparing RocklatanTM to Rhopressa® and latanoprost.
mercury1.jpg
Similar to Mercury 1, Mercury 2 achieved its 90-day primary efficacy endpoint of demonstrating statistical superiority over each of its components at all measured time points. The study evaluated patients with maximum baseline IOPs ranging from above 20 to below 36 mmHg at nine measured time points over the trial. The IOP-reducing effect of RocklatanTM exceeded that of monotherapy with latanoprost in a range of 1.5 to 2.4 mmHg and Rhopressa® in a range of 2.2 to 3.3 mmHg, with efficacy levels remaining consistent for all arms of the study throughout the trial. Similar to Mercury 1, RocklatanTM reduced mean diurnal IOPs to 16 mmHg or lower in 56% of patients, a significantly higher percentage than observed in the comparator arms of the study. The most common RocklatanTM adverse event observed in the study was conjunctival hyperemia, which was reported in approximately 55% of patients, and was scored as mild for approximately 70% of affected patients. Other ocular adverse events reported in approximately 5% to 13% of patients in the RocklatanTM group included corneal verticillata, conjunctival hemorrhage and corneal disorder (asymptomatic change in appearance of corneal endothelial cells). In addition, tolevels of IOP reduction in Mercury 2 were consistent with those observed in the Mercury 1 90-day efficacy results for all arms of the study.

Pipeline Opportunities
We are evaluating our primary product candidates, Rhopressa™ and Roclatan™, we are also exploring the longer-term impact of Rhopressa™on the diseased trabecular meshwork, as well as for neuroprotection, and evaluating possible uses of our existing proprietary portfolio of Rho Kinaseowned ROCK inhibitors for additional indications within and beyond glaucoma. In February 2015, we issued a research update onOur owned preclinical results demonstratingsmall molecule, AR-13503 has demonstrated the potential for Rhopressa™ to have disease-modifying activitythe treatment of DME, wet AMD and related diseases of the retina by inhibiting ROCK and Protein kinase C. AR-13503, which has the same active metabolite as Rhopressa®, has shown lesion size decreases in glaucoma patients by stopping fibrosis an in the trabecular meshwork, and also increasing perfusion in the trabecular outflow pathway thus increasing both drainage and the deliveryvivo preclinical model of nutrientswet AMD at levels similar to the diseased tissue. Additionally, our preclinical smallcurrent market-leading wet AMD anti-VEGF product. When used in combination preclinically with the market leading anti-VEGF product, AR-13503 produced greater lesion size reduction than the anti-VEGF product alone in a model of proliferative DR. This molecule AR-13154, has shown preclinicallynot yet been tested in humans in a clinical trial setting. Pending additional studies, AR-13503 may have the potential to decrease lesion sizeprovide an entirely new mechanism and pathway to treat DME, wet AMD and related diseases of the retina. Since AR-13503 is a small molecule with a short half-life, and the aforementioned diseases are located in wet age-relatedthe back of the eye, a delivery mechanism is needed to deliver the molecule to the back of the eye for a sustained delivery period.
To that end, in July 2017, we announced that we entered into a collaborative research, development and licensing agreement with DSM. The research collaboration agreement includes an option to license DSM’s bio-erodible polymer implant technology for sustained delivery of certain Aerie compounds to treat ophthalmic diseases. In August 2018, we announced the expansion of our collaboration with DSM to provide for (i) a worldwide exclusive license for all ophthalmic indications to DSM’s polyesteramide polymer technology, (ii) continuation of the collaborative research initiatives through the end of 2020, including the transfer of DSM’s formulation technology to Aerie during that time and (iii) access to a preclinical latanoprost implant. This technology uses polyesteramide polymers to produce an injectable, thin fiber that is minute in size. Preclinical experiments have demonstrated early success in conjunction with AR-13503, including demonstration of linear, sustained elution rates over several months and achievement of target retinal drug concentrations. We expect to submit an IND for the AR-13503 sustained-release implant in the first quarter of 2019.
Further, in October 2017, we acquired the rights to use PRINT® technology in ophthalmology and certain other assets from Envisia. PRINT® is a proprietary technology capable of creating precisely-engineered sustained release products utilizing fully-scalable manufacturing processes. In addition, we acquired Envisia’s intellectual property rights relating to Envisia’s preclinical dexamethasone steroid implant for the potential treatment of macular degeneration (AMD) at numerically higher levels thanedema due to RVO that utilizes the PRINT® technology, which we refer to as AR-1105. The IND for this sustained-release implant was submitted in December 2018. In January 2019, we announced that the FDA reviewed the IND for AR-1105 and it is now in effect, allowing Aerie to initiate human studies in the treatment of macular edema due to RVO. We expect to initiate a Phase 2 clinical study for AR-1105 in the first quarter of 2019. We are also evaluating the PRINT® technology platform for sustained release of therapies to the front of the eye, including to potentially treat open-angle glaucoma or ocular hypertension. We commenced operation of our current market-leading product.Good Manufacturing Practices (“cGMP”)-validated manufacturing facility for production of ophthalmic implants using PRINT® technology in our Durham, North Carolina, facility in October 2018.
We may continue to enter into research collaboration arrangements, license, acquire or develop additional product candidates and technologies to broaden our presence in ophthalmology. In August 2015ophthalmology, and September 2015, we entered into collaboration and license arrangements with GrayBug, Inc. and Ramot at Tel Aviv University, Ltd., respectively, neither of which represents a material financial commitment by Aerie. Our collaboration with GrayBug is focused on researching the potential use of their biodegradable polymer technology to deliver a version of AR-13154 to the back of the eye over a sustained period of time. With Ramot, we are evaluating a Ramot preclinical anti-beta amyloid small molecule, named EG-30, for neuroprotection in glaucoma and reduction of geographic atrophy in advanced dry AMD. We continually explore and discuss potential additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners.
Further, we are also currently screening our owned library of ROCK inhibitors for indications beyond glaucoma considering that third-party studies and trials have demonstrated potential for ROCK inhibition in treating certain disease categories. We own the worldwide rights to all indicationsare initially focused on exploring potential opportunities for our current Aerie product candidates. Our intellectual property portfolio contains patentsmolecules in pulmonary health, dermatology and pending patent applications related to composition of matter, pharmaceutical compositions and methods of use for our product candidates.cancers. We have patent protection for our primary product candidates, Rhopressa™ and Roclatan™ ,are in the United States through at least 2030.

In March 2015, we revised our corporate structure to align with our business strategy outside of North America by establishing Aerie Pharmaceuticals Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands (“Aerie Limited”). In addition, we assigned the beneficial rights to our non-U.S. and non-Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, we and Aerie Limited entered into a research and development agreement and cost sharing agreement pursuant to which we and Aerie Limited will share the costs of the development of intellectual property. Additionally, in April 2015, we continued to prepare for foreign-based activities and established Aerie Pharmaceuticals Ireland Limited (“Aerie Ireland Limited”) as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited. We are currently evaluating the possibility of constructing an Aerie manufacturing plant in Ireland.Glaucoma Overview
As indicated earlier, glaucomaGlaucoma Market Overview
Glaucoma is one of the largest segments in the global ophthalmic market. In 2014,2017, branded and generic glaucoma product sales exceeded $4.7were approximately $5.0 billion in the United States, Europe and Japan in aggregate, according to IMS.IQVIA. Prescription volume for glaucoma products in the United States alone exceeded 33was 37 million, representing 61 million bottles in 20142017, and is expected to grow, driven in large part by the aging population.

The PGA and non-PGA market segments each represent approximately one-half of the prescription volume in the U.S.United States glaucoma market, as shown in the following pie chart, which is based on IMSIQVIA data.


usglaucomamarket2017a02.jpg
According to the National Eye Institute, it is estimated that over 2.7 million people in the United States suffer from glaucoma, a number that is expected to reach approximately 4.3 million by 2030. Furthermore, The Eye Diseases Prevalence Research Group has estimated that only half of the nation’sU.S. glaucoma sufferers know that they have the disease. Glaucoma is a progressive and highly individualized disease, in which elevated levels of IOP are associated with damage to the optic nerve, resulting in irreversible vision loss and potentially blindness. Patients may suffer the adverse effects of glaucoma across a wide range of IOP levels, including within the “normotensive” range of 10 mmHg to 21 mmHg, which is generally accepted as the level of IOP in healthy individuals.levels. There are multiple factors that can contribute to an individual gettingdeveloping glaucoma, including, but not limited to, age, family history and ethnicity. For example, there generally is a higher incidence and severity of the disease in African-American and Hispanic populations. Based on data from the Baltimore Eye Survey, approximately 80% of glaucoma patients have low to moderately elevated IOP at the time of diagnosis and approximately 60% of glaucoma patients have IOP of 21 mmHg or below at the time of diagnosis. Additionally, in Japan, the Tajimi Study found that approximately 90% of glaucoma patients had IOP of 21 mmHg or below at the time of diagnosis. In clinical trials to date, Rhopressa™ has demonstrated the ability to provide relatively consistent IOP lowering across all tested baseline IOP levels, which we believe differentiates it from currently marketed drugs that have shown reduced efficacy at lower baseline IOPs.
Glaucoma is treated by the reduction of IOP, which has been shown to slow the progression of vision loss. In a healthy eye, fluid is continuously produced and drained in order to maintain pressure equilibrium and provide nutrients to the eye tissue. The FDA recognizes sustained loweringreduction of IOP as the primary clinical endpoint for the approval of drugs to treat patients with glaucoma and ocular hypertension. The primary drainage mechanism of the eye is the trabecular meshwork, or TM, which accounts for approximately 80% of fluid drainage in a healthy eye, while the secondary drainage mechanism, the uveoscleral pathway, is responsible for the remaining drainage. In glaucoma patients, damage to the TM results in insufficient drainage of fluid from the eye, which causes increased IOP and damage to the optic nerve. In addition to eye fluid production and drainage through the TM and uveoscleral pathway, episcleral venous pressure, or EVP, makes a significant contribution to IOP. EVP represents the pressure of the blood in the episcleral veins of the eye where the eye fluid drains into the bloodstream. Historical

3



studies have shown that EVP accounts for approximately half of IOP in normotensive subjects and approximately one-third of IOP in patients with pressures of 24 to 30 mmHg. When EVP is lowered, fluid is able to flow more freely from the eye. Drugs that lower IOP without lowering EVP are most effective at high IOPs, where EVP is believed to contribute less to IOP, and are less effective at lower IOPs, where EVP is seen to account for a larger portion of IOP.
Once glaucoma develops, it is a chronic condition that requires life-long treatment. The initial treatment for glaucoma patients is typically the use of prescription eye drops. PGAs have become the most widely prescribed glaucoma drug class. The most frequently prescribed PGA is once-daily latanoprost. The most commonly prescribed non-PGA drugs belong to the beta blocker class. The most frequently prescribed beta blocker is twice-daily timolol. Other non-PGA drug classes include the alpha agonists and carbonic anhydrase inhibitors. When PGA monotherapy is insufficient to control IOP or contraindicated due to concerns about side effects, non-PGA products are used either as add-on therapy to the PGA or as an alternative monotherapy. It is estimated that up to 50% of glaucoma patients receiving PGA monotherapy require add-on therapy within two years of initial prescription of the drug, in ordersuch PGA monotherapy to maintain adequate control of IOP. It is believed that this rise in IOP after a patient is on an initial therapy results from the lack of effect of current therapies on the TM, and as a result damage to the TM progresses and the IOPs begin to rise.
Based on our preclinical studies and clinical trials to date, our product candidates represent a new class of drugs utilizing novel MOAs that are applied topically as once-daily eye drops. Currently approved drugs mainly reduce IOP by increasing fluid outflow through the eye’s secondary drain with once-daily dosing or reducing fluid inflow by decreasing fluid production with multiple doses per day. Rhopressa™ lowers IOP through a triple MOA that (i) relaxes the contracted tissue of the TM to improve fluid outflow through the eye’s primary drain, (ii) decreases fluid production in the eye and (iii) lowers EVP, an MOA that we believe further differentiates Rhopressa™ from currently marketed glaucoma products. Roclatan™, our quadruple-action fixed-combination product candidate, combines the triple MOA of Rhopressa™ with latanoprost, a PGA that increases fluid drainage through the uveoscleral pathway.
We believe there are significant unmet needs in the glaucoma market as is evident by the degree of use of multiple therapies to treat patients with the disease and understand that eye-care professionals are eager for new therapy choices. Nonechoices, as we have seen with the early success of the commonly prescribed PGAs or non-PGAs target the TM, the diseased tissue responsible for elevated IOP levels in glaucoma patients and the eye’s primary drain. Moreover,Rhopressa® U.S. commercial launch. PGAs have side effects, contraindications and reduced efficacy in patients with low to moderately elevated IOPs relative to patients with higher IOPs. Non-PGAsOther currently marketed non-PGAs are less efficacious than PGAs, have more serious and a greater number of side effects and contraindications, and require multiple daily doses. As a result, we believe there is a significant unmet need in both the PGA and non-PGA market segments, each of which represents approximately one-half of the U.S. and European glaucoma market based on prescription volumes.volumes, according to IQVIA. Despite the limitations of existing glaucoma drugs, Xalatan® (latanoprost), the best-selling PGA, together with Xalacom®, its fixed-combinationfixed-dose combination with a beta blocker, which is not available in the United States, generated peak annual global revenues of approximately $1.7 billion prior to the introduction of their generic equivalents, and the most commonly prescribed non-PGA drugs each generated peak annual global revenues of over $400 million prior to the introduction of their generic equivalents.
We believe Rhopressa™ may be prescribed by eye-care professionals as an add-on drug of choice for patients taking PGAs, due to the MOAs of Rhopressa™ being complementary to the MOA of PGAs, and due its IOP-lowering ability, more convenient dosing and better tolerability profile compared to currently marketed non-PGA add-on products.
In addition to the expected primary use of Rhopressa™ as an adjunctive therapy, we also believe Rhopressa™ may be prescribed by eye-care professionals in the following circumstances:
As a preferred alternative therapy for patients who do not respond to PGAs.
As a preferred initial therapy for patients with low or normal-tension glaucoma.
As a preferred initial therapy where PGAs are contraindicated and for patients who choose to avoid the cosmetic issues associated with PGAs, including iris color change in light-eyed patients, discoloration of tissue surrounding the eyes and eyelid droopiness and sunken eyes caused by loss of orbital fat.
In addition, based on our preclinical data to date, we believe that quadruple-action Roclatan™ would be the only glaucoma product that covers the full spectrum of currently known IOP-lowering MOAs, giving it the potential to provide a greater IOP-lowering effect than any currently approved glaucoma product. Therefore, we believe Roclatan™ could compete with both PGA and non-PGA therapies for patients requiring maximal IOP lowering, including those with higher IOPs and those who present with significant disease progression despite currently available therapies.
We currently plan to commercialize our products ourselves in North America, may commercialize ourselves in Europe and plan to explore partnership opportunities through collaboration and licensing arrangements in certain key markets outside of North

America, including Europe and Japan, where as noted in the Tajimi study, glaucoma patients tend to have lower IOPs, in ranges where currently marketed products tend to be less effective.

Our primary product candidates, triple-action Rhopressa™ (netarsudil ophthalmic solution) 0.02%, and quadruple-action Roclatan™ (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005%, are once-daily eye drops. The references to triple and quadruple action are supported by our preclinical studies and clinical trials to date. Rhopressa™ inhibits Rho Kinase, or ROCK, and the norepinephrine transporter, or NET, which are both novel biochemical targets for lowering IOP. By inhibiting these targets, we believe Rhopressa™ reduces IOP via three separate MOAs: (i) through ROCK inhibition, it increases fluid outflow through the TM, which accounts for approximately 80% of fluid drainage from the eye; (ii) also through ROCK inhibition, as demonstrated in a preclinical study, it reduces EVP, which represents the pressure of the blood in the episcleral veins of the eye where eye fluid drains into the bloodstream; and (iii) through NET inhibition, it reduces the production of eye fluid. Roclatan™, a single-drop fixed-dose combination of Rhopressa™ and latanoprost, lowers IOP through the same three MOAs as Rhopressa™ and, as a fourth MOA, through the ability of latanoprost to increase fluid outflow through the uveoscleral pathway, the eye’s secondary drain. All of these observations represent findings from Aerie’s body of preclinical and clinical work, as applicable.
We discovered and developed our product candidates internally through a rational drug design approach that coupled medicinal chemistry with high content screening of compounds in proprietary cell-based assays. We selected and formulated our product candidates for preclinical in vivo testing following a detailed characterization of over 3,000 synthesized ROCK-selective and ROCK/NET inhibitors. We continue to seek to discover and develop new compounds in our research laboratories and employ a scientific staff with expertise in medicinal chemistry, analytical chemistry, biochemistry, cell biology, pharmacology and pharmaceutical science.
The following table summarizes each of our existing product candidates, their MOAs and their development status, as well as our intellectual property rights for these product candidates.

In 2015, we decided to no longer actively pursue further development of AR-13533, a second generation ROCK/NET inhibitor, merely for strategic business purposes. We have not yet submitted an IND for AR-13533 to the FDA.
Rhopressa®
Rhopressa™ is the first of a new class of glaucoma drug products that was discovered by our scientists. It is a once-daily eye drop designed to reduce IOP in patients with glaucoma or ocular hypertension. Based on our preclinical and clinical observations, it increases fluid outflow through the primary drain of the eye while also reducing eye fluid production. In addition, a preclinical study demonstrated reduction of EVP as an additional MOA of Rhopressa™, as further described below. The active ingredient in Rhopressa™, AR-13324, acts through the inhibition of both ROCK and NET.
ROCK is a protein kinase, which is an enzyme that modifies other proteins by chemically adding phosphate groups to them. Specifically, ROCK regulates actin and myosin, which are proteins that are responsible for cellular contraction. ROCK activity also promotes the production of extracellular matrix proteins. ROCK inhibitors block TM cell contraction and reduce the production of extracellular matrix, thereby improving fluid outflow and consequently decreasing IOP. In addition, we believe ROCK inhibition may also be responsible for reduction of EVP. EVP represents the pressure of the blood in the episcleral veins of the eye, where eye fluid drains into the bloodstream. When EVP is lowered, the fluid is able to flow more freely from the eye.
NET is a protein that transports norepinephrine across neuronal cell membranes. Norepinephrine is a chemical released by neurons to communicate with targeted cells. NET returns excess norepinephrine back into the neuron, which helps end the signaling between the neuron and the neuron’s target cells. We believe the inhibition of NET prolongs the activation of target

cells in the ciliary body of the eye, which reduces the production of eye fluid and thereby lowers IOP. Based on our clinical trials, we have observed that Rhopressa™ may also have a potential synergisitic effect with PGAs, whereby its IOP-lowering ability is increased when patients take a PGAprescribed by eye-care professionals as a first line therapy.
Rhopressa™ is expected to compete primarily in thepreferred adjunctive therapy market, which represents approximately one-half of the U.S. glaucoma prescription market, which totaled 33 million prescriptions in 2014 according to IMS. Currently marketed adjunctive therapies are older generation products that are generally dosed two to three times a day, have MOAs focused on fluid production reduction, often have lower efficacy levels and have systemic side effects. We believe Rhopressa™ will be able to compete with these productsfor patients taking PGAs, due to its effective IOP-lowering at relatively consistent levels across tested IOPs including theIOP-reducing ability, to lower EVP, targeting of the diseased tissue, potential synergistic effect with PGAs,more convenient once-daily dosing and favorablebetter tolerability profile with lack of systemic side effects.
Based on the Rhopressa™ Rocket 1 and Rocket 2 Phase 3 registration trial results, Phase 2b clinical trial results, performance of Rhopressa™ in the Roclatan™ Phase 2b clinical trial and the several positive differentiating attributes of Rhopressa™, we believe Rhopressa™ has the potential to be the future drug of choice as adjunctive therapy to PGAs when additional IOP lowering is desired and as an initial therapy for PGA non-responders or for patients with low or normal-tension glaucoma and those with tolerability concerns.
RhopressaPhase 3 Efficacy Results
Our Phase 3 registration trials commenced in July 2014 and are designed to use timolol as the comparator, as timolol represents the most widely used comparator in registration trials in glaucoma, and is also the most widely prescribed non-PGA drug. We anticipate a total enrollment of approximately 2,030 patients in our Phase 3 registrations trials of Rhopressa™. Phase 3 efficacy results are determined after three months of treatments and safety results are analyzed and submitted following 12 months of treatment.
In April 2015, we completed our initial Phase 3 registration trial, named “Rocket 1,” which was designed to measure efficacy over three months. Baseline IOP was measured prior to treatment. Following treatment, IOP was measured at 8 a.m., 10 a.m. and 4 p.m. at the end of week two, week four and day 90. This trial included 182 patients in the Rhopressa™ once-daily (QD) arm and 188 patients in the timolol twice-daily (BID) arm. The baseline IOPs tested in the trial ranged from above 20 to below 27 mmHg. Rhopressa™did not achieve its primary endpoint of demonstrating non-inferiority of IOP lowering for Rhopressa™ compared to timolol for patients with IOP below 27 mmHg, but did achieve its pre-specified secondary endpoint, demonstrating non-inferiority of IOP lowering for Rhopressa™ compared to timolol for patients with IOP below 24 mmHg. We believe the lack of success at the top end of the range is attributed, at least in part, to patient non-compliance and the probability that certain patient baseline IOP levels exceeded the entry criteria of below 27 mmHg.
For the Rhopressa™ population of patients with IOP below 27 mmHg in Rocket 1, the mean difference from timolol ranged from -0.4 to +1.3 mmHg at a 95% confidence interval. For the population of patients with IOP below 26 mmHg, Rhopressa™ met the criteria for non-inferiority to timolol at all 9 time points and was numerically superior to timolol at the majority of time points. For the prespecified population of patients with IOP below 24 mmHg, Rhopressa™ met the criteria for non-inferiority to timolol at all 9 time points and was numerically superior to timolol at all 9 time points.
No drug-related serious adverse events, or SAEs, were identified during the Rocket 1 trial. The primary adverse event was conjunctival hyperemia, or eye redness, which was experienced by approximately 35% of the Rhopressa™patients, of which approximately 80% was reported as mild. Conjunctival hyperemia was measured by biomicroscopy at 8am at the end of week two, week four and day 90. Across the population of patients on Rhopressa™, approximately 5% to 13% of subjects experienced conjunctival hemorrhage, erythema of the eyelid, blurry vision and or corneal deposit.
Our second Phase 3 registration trial, named “Rocket 2,” is designed to measure efficacy over three months and safety over 12 months. The Rocket 2 trial includes Rhopressa™ dosed both once-daily, or QD, and twice daily, or BID. After evaluating Rocket 1 efficacy results, we obtained agreement from the FDA to change the IOP range for the primary endpoint for the Rocket 2 trial to baseline IOP below 25 mmHg. This modified clinical endpoint range was set to a level where Rocket 1 would have been successful.
In September 2015, the Rocket 2 trial achieved its primary efficacy endpoint of demonstrating non-inferiority of IOP lowering for Rhopressa™QD and BID compared to timolol BID. The baseline IOPs tested in the trial ranged from pre-study baseline IOPs of above 20 mmHg to below 25 mmHg. The study included a Rhopressa™ BID arm at the request of the FDA, because it is known that PGAs are less efficacious when dosed BID, and we believe there was interest in discovering how Rhopressa™ BID would perform. Baseline IOP was measured prior to treatment. Following treatment, IOP was measured at 8 a.m., 10 a.m.

6



and 4 p.m. at the end of week two, week six and day 90. The trial included 129 patients in the Rhopressa™QD arm, 132 patients in the Rhopressa™BID arm and 142 patients in the timolol twice-daily arm. The most common Rhopressa™adverse event in the QD arm was conjunctival hyperemia, or eye redness, which was reported as 35% increased incidence, of which 83% was mild and 16% moderate. Other ocular adverse events occurring in approximately 5% to 15% of patients in the Rhopressa™QD arm included conjunctival hemorrhage, corneal deposits and blurry vision. The Rhopressa™BID arm showed slightly higher efficacy, but had a higher incidence of adverse events which led to a greater number of early terminations in comparison to the Rhopressa™QD arm. Other ocular adverse events occurring in approximately 5% to 17% of patients in the Rhopressa™QD arm included conjunctival hemorrhage, corneal deposits, blurry vision, increased lacrimation, reduced visual acuity, eye pruritus, and conjunctival edema. In February 2016, safety data for the 12-month period of the Rocket 2 trial confirmed this positive safety profile for the drug and demonstrated a consistent IOP lowering effect throughout the 12-month period at the 8 a.m. timepoint.
After detailed analysis of the Rocket 1 and Rocket 2 results, we observed higher levels of IOP lowering for Rhopressa™ at week two and to a lesser extent at week six stemming from patients who were previously on a PGA, pointing to the potential synergistic effect of PGAs and Rhopressa™, which decreases over the 90-day period as the residual PGA effect subsides. For all other patients, the IOP lowering was consistent across the 90 day measurement periods. For illustrative purposes, the graphic below shows the performance of Rocket 1 and Rocket 2 at baselines above 20 mmHg and below 25 mmHg, compared to timolol.
In addition to our Rocket 1 and Rocket 2 trials, we are currently conducting a one year, safety-only study for Rhopressa™ in Canada, named “Rocket 3,” which commenced in September 2014, and an additional Phase 3 registration trial for Rhopressa™, named “Rocket 4,” which commenced in September 2015. Rocket 4 is designed to gain adequate six-month safety data for regulatory filings in Europe. Based upon discussions with the FDA, we expect to file a NDA for Rhopressa™ in the third quarter of 2016, utilizing Rocket 2 as the pivotal clinical trial and Rocket 1 as supportive. Neither Rocket 3 nor Rocket 4 is required for the NDA filing.
Rhopressa™ Preclinical Anti-Fibrotic and Perfusion Results

We continue to explore the potential longer-term impact of Rhopressa™ on the trabecular meshwork. By increasing trabecular outflow, as demonstrated in our preclinical studies, Rhopressa™, has the potential to stop the degeneration of outflow tissues. As part of the aging process, the trabecular meshwork becomes stiffened and clogged as fibrosis develops and progresses. Preclinical studies on human trabecular meshwork cells have demonstrated a meaningful anti-fibrotic effect from Rhopressa™. Further, additional preclinical experiments on human eyes have demonstrated the product candidate’s potential ability to increase the perfusion of the trabecular meshwork and downstream outflow tissues. We believe this is possible because as a

7



result of the action of Rhopressa™ the trabecular meshwork becomes relaxed and opens, which increases the flow of eye fluid, or aqueous humor. This has the potential to increase the health of the trabecular outflow tissues, since it should increase the delivery of nutrients and antioxidants to the trabecular meshwork that were otherwise blocked from passage. The flow of fluid through the trabecular meshwork is the only known mechanism for delivering such nutrients to the diseased tissue, as there are no blood vessels present. Work is continuing as we explore whether our product candidates may be able to prevent, or possibly even reverse, damage to the trabecular meshwork pathway through this potential effect as well as the potential anti-fibrotic effect of our product candidates. If findings are positive and there is demonstrated disease modification, this could be a major breakthrough in the treatment of glaucoma and ocular hypertension.

Roclatan
Our once-daily, quadruple-action product candidate Roclatan™ is a combination of our triple-action compound AR-13324, the active ingredient in Rhopressa™, formulated with latanoprost in a single eye drop. If approved, we believe that Roclatan™ would be the first glaucoma product to lower IOP through all currently known MOAs:
increasing fluid outflow through the TM, the eye’s primary drain,
reducing fluid production in the eye,
reducing EVP, and
through the MOA of latanoprost, increasing fluid outflow through the uveoscleral pathway, the eye’s secondary drain.
RoclatanTM Phase 3 Development Strategy
Our Phase 3 registration trials commenced in September 2015. We anticipate a total enrollment of approximately 1,840 patients in our Phase 3 registrations trials. Our initial Phase 3 registration trial, named “Mercury 1,” is a 12-month safety trial with a 90-day interim efficacy readout, which commenced in September 2015. We expect Mercury 1 topline 90-day efficacy data in the third quarter of 2016 and topline 12-month safety data in the third quarter of 2017. Our second Phase 3 registration trial, named “Mercury 2,” is a 90-day efficacy and safety trial, which is expected to commence in March 2016. Both trials are designed to demonstrate the superiority of Roclatan™ to each of its components. If both Mercury 1 and Mercury 2 are successful, we expect to file an NDA for Roclatan™in the second half of 2017, approximately one year after the NDA filing for Rhopressa™.
We also plan to initiate a third Phase 3 registration trial, named “Mercury 3,” in the first half of 2017. Mercury 3 will be designed to compare Roclatan™ to a fixed dose combination product broadly marketed in Europe, which if successful should improve our commercialization prospects in that region.
RoclatanTM Phase 2 Efficacy Results
In June 2014, we completed a 28-day Roclatan™ Phase 2b clinical trial. The baseline IOPs tested in the study ranged from 22 to 36 mmHg and included 297 patients who were treated once daily with Roclatan™ 0.01%, Roclatan™ 0.02%, Rhopressa™ 0.02%, or latanoprost. The primary efficacy endpoint for this Phase 2b clinical trial was statistical superiority of Roclatan™over each of its components on day 29. Baseline IOP was measured prior to treatment. Following treatment, IOP was measured on day eight, day 14 and day 28 at 8 a.m., 10 a.m. and 4 p.m. We observed statistical superiority over the individual components at all time points.

Roclatan™ vs. Individual Components
Mean IOP at All Time Points (p<0.001)


Roclatan™ 0.02% lowered mean diurnal IOP on day 29 from 25.1 mmHg at baseline to 16.5 mmHg, a 34% decrease in IOP. Roclatan™ 0.02% was determined to be 1.6 - 3.2 mmHg more efficacious than latanoprost and 1.7 - 3.4 mmHg more efficacious than RhopressaTM.
An additional analysis that compared the response results for patients on day 29 revealed that 50% of Roclatan™patients compared to 28% of latanoprost patients experienced a 35% or greater decrease in mean diurnal IOP from baseline on day 29. Furthermore, 46% of Roclatan™ patients compared to 18% of latanoprost patients had a mean diurnal IOP of 16 mmHg or less on day 29. From a safety perspective, Roclatan™ was well tolerated. The most common Roclatan™ adverse event was hyperemia, or eye redness, which was reported in 40% of patients. For patients who experienced hyperemia, 80% were observed as mild through biomicroscopy findings. Additionally, there were no systemic drug-related adverse events reported.
We believe Roclatan™, if approved, would be the only glaucoma product that covers the full spectrum of currently known IOP- lowering MOAs, giving it the potential to provide a greater IOP-lowering effect than any currently marketed glaucoma product. Therefore, we believe Roclatan™ could compete with both PGA and non-PGA therapies for patients requiring maximal IOP lowering, including those with higher IOPs and those who present with significant disease progression despite currently available therapies.

Pipeline Opportunities

AR-13154
One of our owned preclinical molecules, AR-13154, has demonstrated the potential for the treatment of wet AMD. This preclinical small molecule inhibits Rho kinase, JAK2 and PDGFR-β, and has shown lesion size decreases in a model of wet AMD at levels similar to or better than current market-leadingadjunctive products. If proven out, we may have the potential to provide an entirely new mechanism and pathway to treat this disease. Further, in our preclinical studies, we have seen a promising effect of this molecule on reducing neovascularization in a model of proliferative diabetic retinopathy.

The graph below depicts the results of a preclinical study designed to show the impact of AR-13154 and Eylea® on laser-induced choroidal neovascularization, or CNV, in rats.

Since AR-13154 is a small molecule with a short half-life, and the aforementioned diseases are located in the back of the eye, a delivery mechanism is needed to deliver the molecule to the back of the eye for a sustained delivery period. As a result, in mid-2015 we established a research collaboration with GrayBug, a drug delivery technology spin-out from Johns Hopkins University. We believe that their biodegradable polymer technology may be effective in facilitating delivery of our small molecules, including AR-13154, over a sustained period, such as six months. The technology may also prove useful in delivering other Aerie molecules to the front of the eye, such as for the purpose of long term IOP lowering.

EG-30
Another small molecule that may benefit from delivery technology is EG-30, a preclinical anti-beta amyloid product candidate that we are researching in collaboration with Ramot at Tel Aviv University. We believe that EG-30, Ramot’s product candidate, has the potential for neuroprotection and reduction of geographic atrophy in advanced dry AMD.

Our Strategy
Our goal is to become a leader in the discovery, development and commercialization of innovative pharmaceutical products for the treatment of patients with glaucoma and other diseases of the eye. We believe our product candidates have the potential to address many of the unmet medical needs in the glaucoma market. Key elements of our strategy are to:
Advance the development of our product candidates to approval. We expect to file the NDA for Rhopressa™ (netarsudil ophthalmic solution) 0.02% in the third quarter of 2016, using our successful Rocket 2 clinical trial as the pivotal trial and Rocket 1 data as supportive. This will be a key step in driving this drug to a commercial stage in the United States. Our Rocket 4 trial, which is ongoing, is designed to provide adequate six-month safety data to support a filing with the European MAA by approximately mid-2017.

Our second product candidate, once-daily, quadruple-action Roclatan™ (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005%, which is a fixed-dose combination of Rhopressa™ and latanoprost, the most commonly prescribed drug for the treatment of patients with glaucoma, successfully completed a Phase 2b clinical trial in patients with open-angle glaucoma and ocular hypertension in June 2014. Our first Phase 3 registration trial for Roclatan™, named “Mercury 1,” commenced in September 2015. We expect to commence our second Phase 3 trial for Roclatan™, named “Mercury 2,” in March 2016. If both Mercury 1 and Mercury 2 are successful, we expect to file an NDA for Roclatan™ in the second half of 2017, approximately one year after the NDA filing for Rhopressa™. We expect to commence a third Phase 3 registration trial for Roclatan™, named “Mercury 3,” in Europe in the first half of 2017, which will be designed to compare Roclatan™ to a fixed dose combination product broadly marketed in Europe, which if successful should improve our commercialization prospects in that region.

We currently have research collaboration arrangements with GrayBug Inc., for drug delivery technology, and Ramot at Tel Aviv University Ltd., for a small molecule anti-beta amyloid product candidate with the potential for neuroprotection and treatment of advanced dry AMD.
Glaucoma Medical Overview
Glaucoma is generally characterized by relatively high IOP as a result of impaired drainage of fluid, known as aqueous humor, from the eye. The FDA recognizes sustained loweringreduction of IOP, measured in terms of mmHg, as the primary clinical endpoint for regulatory approval, making clinical trials for this indication relatively straight-forward due to easily measured objective parameters.
In a healthy eye, aqueous humor is continuously produced and drained from the eye in order to maintain pressure equilibrium and provide micronutrients to various tissues in the eye. An insufficient drainage of fluid can increase IOP above normal levels, which can eventually cause damage to the optic nerve. The normal range of IOP is generally between 10 and 21 mmHg. Several studies have demonstrated that the significant majority of glaucoma patients have IOPs belowbetween 21 and 26 mmHg at the time of diagnosis. An insufficient drainage of fluid can increase IOP above normal levels, which can eventually cause damage to the optic nerve. Once damaged, the optic nerve cannot regenerate and thus damage to vision is permanent.
The most common form of glaucoma is open-angle glaucoma, which is characterized by abnormally high IOP as a result of impaired drainage of fluid from the eye’s primary drain, the TM. Open-angle glaucoma is a progressive disease leading to vision loss and blindness for some patients as a result of irreversible damage to the optic nerve.
Studies of the disease have demonstrated that reducing IOP in patients with glaucoma can help slow or halt further damage to the optic nerve and help preserve vision. Once diagnosed, glaucoma requires life-long treatment to maintain IOP at lower levels based on the individual patient’s risk of disease progression. Ophthalmologists will routinely determine a target IOP, which represents the desired IOP level to achieve with glaucoma therapy for an individual patient. Should the disease progress even once the initial target IOP is reached, further loweringreduction of the IOP has been shown to help in preventing additional damage to the optic nerve and further vision loss. This may require loweringreducing IOP until it is in the so-called “low normal range” of 12 mmHg to 14 mmHg to protect the optic nerve from further damage.
There are multiple factors that can contribute to an individual gettingdeveloping open-angle glaucoma, including, but not limited to, age, family history and ethnicity. For example, there generally is a higher incidence and severity of the disease in African-American and Hispanic populations.
Some patients with high IOP are diagnosed with a condition known as ocular hypertension. Patients with ocular hypertension have high IOP without the loss of visual fields or observable damage to the optic nerve and are at an increased risk of developing glaucoma. These patients are commonly treated in the same manner as glaucoma patients.

The following diagram illustrates how increased IOP eventually leads to increased pressure on the optic nerve, resulting in gradual loss of vision and ultimately visual disability and blindness.

f-eyewithglaucomaa02.jpg
The ciliary body in the eye is the tissue that produces aqueous humor, the production of which is commonly referred to as fluid inflow. The fluid leaves the eye primarily through the TM, the process of which is commonly referred to as fluid outflow. The healthy eye maintains a state of IOP homeostasis through a constant physiological process of aqueous humor production and drainage. The deteriorating function of the TM in glaucoma leads to increased resistance to fluid outflow and higher IOP. There is also a secondary drain for the fluid in the eye known as the uveoscleral pathway, which is typically responsible for approximately 20% of fluid drainage.

In addition to aqueous humor production and drainage through the TM and uveoscleral pathway, EVPepiscleral venous pressure (“EVP”) plays a significant role in the regulation of IOP. EVP represents the pressure of the blood in the episcleral veins of the eye which are the site of drainage of eye fluid into the bloodstream. Historical studies have shown that EVP accounts for approximately 10 mmHg of IOP, or approximately one-half of IOP in patients with pressures near the normotensive subjectslevel of 21 mmHg, and approximately one-third of IOP in patients with pressures of 24 mmHg to 30 mmHg. When EVP is lowered, aqueous humor is able to flow more freely from the eye.
Patients are diagnosed through measurements of IOP using Goldmann applanation tonometry, the standard device used by clinicians to measure IOP, along with an evaluation of visual fields and observing the appearance of the optic nerve. These tests are routinely carried out by eye-care professionals. The initial treatment for patients diagnosed with open-angle glaucoma or ocular hypertension is typically a PGA eye drop. PGAs are designed to lowerreduce IOP by increasing outflow through the eye’s secondary fluid drain. An eye-care professional will then measure a patient’s response to the drug over the first few months. It has been shown that up to 50% of glaucoma patients require more than one drug to treat their IOP. This may occur as early as three to six months after initiating treatment with a PGA. The eye-care professionals may then add a second drug from one of the non-PGA classes, to be used together with the initial drug, or switch to a fixed-combinationfixed-dose combination of two drugs in a single eye drop, or select an alternative single treatment. The reason so many patients eventually need more than one drug is generally considered to be a reflection of the progressive nature of the disease at the TM.
In severe glaucoma cases, patients may need to undergo an invasive surgical procedure. Trabeculectomy is the most common glaucoma-related surgical procedure, also referred to as filtration surgery, in which a piece of tissue in the drainage angle of the eye is removed, creating an opening to the outside of the eye. The opening is partially covered with a scleral flap, the white part of the eye, and the conjunctiva, the thin membrane covering the sclera. This new opening allows fluid to drain out of the eye, bypassing the clogged drainage channels of the TM to maintain a loweredreduced IOP. Devices called shunts are used in glaucoma surgery to divert fluid in a controlled manner from the inside of the eye to the subconjunctival space bypassing the blocked TM. Generally, the shunts reduce IOP to the extent that the use of drops can be reduced, but often not completely eliminated. Many patients continue to require eye drops even following surgery.
Retinal Diseases
AMD is the leading cause of irreversible vision loss in individuals over 55 years of age in developed countries. Clinically, it manifests in two forms: wet AMD and dry AMD. Wet AMD is responsible for a rapid and substantial vision decline characterized by abnormal growth and leakage of blood vessels that breaks through the Bruch’s membrane into the subretinal pigment epithelium space and/or the subretinal space, leading to exudation, hemorrhage, retinal edema, pigment epithelial detachment and fibrous scarring.
DR is the leading cause of vision loss among working age individuals in developed countries and DME is a common cause of vision loss associated with DR. DME occurs due to retinal microvasculature damage, increase in vascular permeability and loss of blood-retinal barrier leading to interstitial fluid accumulation in the retina, particularly in the region of the macula.
In both diseases, wet AMD and DME, vascular permeability, angiogenesis and inflammation play an important role and VEGF has shown to be a key mediator that has been found to be upregulated. Currently, the standard of care for treating wet AMD and DME is intravitreal injection of VEGF inhibitors (anti-VEGF). In addition, alternative therapeutic approaches for DME are directed towards stopping vascular leakage using laser photocoagulation and intravitreal injection of corticosteroids.
Existing anti-VEGF agents have similar safety and efficacy profiles. Three are the most widely used: bevacizumab, ranibizumab and aflibercept. Although anti-VEGF agents have shown a well-established efficacy profile in wet AMD and DME, a downside of these treatments is that some patients have poor response, experience a loss of efficacy after repeated injections over time or require frequent injections to maintain complete resolution of the exudation/edema. Thus, the need for alternative treatment options with prolonged treatment duration to reduce treatment burden of repeat injections and different mechanism of action to target refractory or non-response to anti-VEGF agents leaves a considerable unmet need.
RVO is the second-most common sight-threatening vascular disorder of the retina after DR. Current estimates put global prevalence at approximately 16 million people affected with the disease in one or both eyes and around 520 new cases per million are reported each year. RVO is the result of thrombus formation in the central, hemi-central or branch retinal vein, often due to compression by adjacent artherosclerotic retinal arteries or vasculitis. The two main complications resulting from RVO are macular edema and retinal ischemia leading to retinal or iris neovascularization. Macular edema is a non-specific response of the retina to a variety of insults and involves the breakdown of the blood-retina barrier at the capillary endothelium, resulting in increased vascular permeability and subsequent leakage of fluids into the adjacent retinal tissues and significant visual disturbances. This reduction in vision may be reversible in the short-term, but chronic macular edema causes irreversible damage to the retina and permanent vision loss. Current options for treating macular edema depend upon the cause and severity

of the condition. In the case of RVO, the goal is to reduce the amount of fluid leakage and decrease the edema, thus leading to improved visual acuity. Argon laser photocoagulation was used for many years to treat macular edema associated with branch RVO, but was less effective in the treatment of central RVO, and was not successful in all patients.
Within the last 10 years, intravitreal (“IVT”) pharmacotherapy has revolutionized the therapeutic options for macular edema-associated retinal vascular diseases. Two classes of medication are currently approved to treat macular edema following RVO; corticosteroids (e.g., dexamethasone IVT implant, OZURDEX) and anti-VEGF agents (e.g., ranibizumab, LUCENTIS®, aflibercept, EYLEA®). While both classes have demonstrated efficacy in RVO patients, the treatment burden remains high, with the anti-VEGFs typically requiring monthly or bi-monthly IVT injections and the dexamethasone implant typically requiring injections approximately once every three months. A corticosteroid implant that remained effective for a longer duration would provide the benefit of reducing the treatment burden on patients while treating the inflammatory components of macular edema that are not addressed by inhibition of VEGF. Additionally, if the dose of corticosteroid could be reduced without compromising efficacy, then there exists the potential for reduced corticosteroid-related adverse events such as cataract formation and increased IOP. We are developing AR-1105, a dexamethasone IVT implant, to address these unmet needs.
Competition
The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our experience and scientific knowledge provide us with competitive advantages, we face competition from established branded and generic pharmaceutical companies, such as Valeant Pharmaceuticals International,for example, Bausch Health Companies Inc., Novartis International AG, Allergan, Inc., Santen Inc. and smaller biotechnology and pharmaceutical companies as well as from academic institutions, government agencies and private and public research institutions, which may in the future develop products or technologies to treat glaucoma or other diseases of the eye. Any product candidatesProducts that we

12



successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. We believe that the key competitive factors affecting the success of our current product candidates,Rhopressa® and RocklatanTM, if approved, are likely to be efficacy and MOAs,their respective MOA(s), safety, convenience, price, tolerability and the availability of reimbursement from government and other third-party payors.payers.
We currently expect to compete directly against companies producing existing and future glaucoma treatment products. The most commonly approved classes of eye drops to lowerreduce IOP in glaucoma are discussed below:
PGA Drug Class
 
Prostaglandin Analogues (PGAs)(“PGAs”). Most PGAs are once-daily dosed eye drops generally prescribed as the initial drug to reduce IOP by increasing fluid outflow through the eye’s secondary drain. They do not target the diseased tissue, or TM. PGAs represent approximately one-half of the U.S. and European prescription volume for the treatment of glaucoma.

Xalatan® (latanoprost), the best-selling PGA, together with Xalacom®, its fixed-combinationfixed-dose combination with a beta blocker, which is not available in the United States, had worldwide peak sales of approximately $1.7 billion before its patent expired in 2012, according to publicly reported sales. The adverse effects of PGAs include conjunctival hyperemia, or eye redness, irreversible change in iris color, discoloration of the skin around the eyes, and droopiness of eyelids caused by the loss of orbital fat. PGAs should be used with caution in patients with a history of intraocular inflammation.
Non-PGA Drug Class
 
Beta Blockers. Beta blockers, with their MOA designed to inhibit aqueous production, are one of the oldest approved drugs for the loweringreduction of IOP. The most commonly used drug in this class is timolol. Beta blockers are less effective than PGAs in terms of IOP loweringreduction and are typically used twice daily. Beta blockers are the most commonly used non-PGA drug. They are used as an initially prescribed monotherapy and as an adjunctadjunctive therapy to PGAs when the efficacy of PGAs is insufficient. Beta blocker eye drops have contraindications in their label as a result of systemic exposure from topical application of the eye drops, potentially leading to cardio-pulmonary events such as bronchospasm, arrhythmia and heart failure.
Topical Carbonic Anhydrase Inhibitors. Carbonic anhydrase inhibitors, with their MOA designed to inhibit aqueous production, are less effective than PGAs and are required to be dosed three times daily in order to obtain the desired IOP lowering.reduction. In published clinical studies of carbonic anhydrase inhibitors, the most frequently reported adverse events reported were blurred vision and bitter, sour or unusual taste. Carbonic anhydrase inhibitors are sulfonamides

and, as such, systemic exposure increases risk of adverse responses such as Stevens Johnson syndrome and blood dyscrasias.
Alpha Agonists. Alpha agonists, with their MOA designed to inhibit aqueous production plus have antheir effect on uveoscleral outflow, are less effective than PGAs and need to be dosed three times daily in order to obtain the desired IOP lowering.reduction. In clinical studies, the most frequently reported adverse reactions that occurred in individuals receiving brimonidine ophthalmic solution, a commonly prescribed alpha agonist, included allergic conjunctivitis, conjunctival hyperemia, eye pruritus, burning sensation, conjunctival folliculosis, hypertension, ocular allergic reaction, oral dryness and visual disturbance.
Despite their modest efficacy, safety and tolerability profiles, the requirement for two to three doses per day, and the fact that they do not target the diseased tissue in glaucoma, the beta blocker, carbonic anhydrase inhibitor and alpha agonist products account for up to one-half of the total prescription volume for the treatment of glaucoma based on historical prescription patterns, with beta blocker timolol being the most widely prescribed non-PGA drug. This is driven by the PGA products not being sufficiently effective as monotherapy for up to half of all glaucoma patients.

Table Fixed-dose combination glaucoma products are also currently marketed in the United States, including Cosopt, the combination of Contentsa beta blocker with a carbonic anhydrase inhibitor, and Combigan, the combination of a beta blocker with an alpha agonist. There are no fixed-dose combinations of PGAs with other glaucoma drugs currently available in the United States.

Many of our competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. In July 2015, Bausch + Lomb Inc., a wholly owned subsidiary of Valeant Pharmaceuticals International, Inc., filed a NDA for a nitric oxide-donating latanoprost, which is currently under review by the FDA for the treatment of open angle glaucoma and ocular hypertension. Early-stage companies are also developing treatments for glaucoma, retinal diseases and other diseases of the eye and may prove to be significant competitors, such as Inotek Pharmaceuticals, which is developing an adenosine receptor agonist.competitors. We expect that our competitors will continue to develop new treatments for glaucoma, retinal diseases and other diseases of theythe eye, which may include eye drops, oral treatments, surgical procedures, implantable devices or laser treatments. Alternative treatments beyond eye drops continue to develop.
Other early-stageEarly-stage companies may also compete through collaborative arrangements with large and established companies. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. These competitors also compete with us in recruiting and retaining qualified scientific, commercial and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer adverse effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours. In addition, our ability to compete may be affected because in many cases insurers or other third-party payors encourage the use of generic products.
Our industry is highly competitive and is currently dominated by generic drugs, such as latanoprost and timolol, in the case of glaucoma treatment, and additional products are expected to become available on a generic basis over the coming years. If anyOur ability to compete may be affected because in many cases insurers or other third-party payers encourage the use of our product candidates are approved, wegeneric products. We expect that theyRocklatanTM, if approved, will be priced at a premium over competitivecompeting generic products and consistent with Rhopressa® and other branded glaucoma drugs.
Sales and Marketing
We are commercializing Rhopressa® and plan to commercialize RocklatanTM, if approved, in the United States with our own focused, specialized sales force. For the launch of Rhopressa®, we hired a commercial team that includes approximately 100 sales representatives targeting approximately 14,000 high prescribing eye-care professionals throughout the United States. This sales force will also be responsible for sales of RocklatanTM, if approved.
We have made significant progress in contracting for formulary coverage for Rhopressa® and will contract for formulary coverage for RocklatanTM, if approved, with U.S. payers for both commercial and Medicare Part D prescription drug plans. We have obtained formulary coverage for Rhopressa® for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans. We expect Medicare Part D Tier 2 equivalent coverage to increase to over 70% by the end of the first quarter of 2019.
Outside of the United States, if we obtain regulatory approval, we currently expect to commercialize Rhokiinsa® and RoclandaTM in Europe on our own, and likely partner for commercialization of their equivalents in Japan.
Major Customers
For the year ended December 31, 2018, a significant percentage of our sales of Rhopressa® were to three large wholesale drug distributors. Sales to McKesson Corporation, Cardinal Health, Inc. and AmerisourceBergen Corporation accounted for 33.9%, 33.3% and 29.7% of total revenues, respectively, for the year then ended.
Manufacturing
AR-13324, the active ingredient in Rhopressa™, is a small molecule and capable of being manufactured in reliable and reproducible synthetic processes from readily available starting materials. We believe the chemistry used to manufacture AR-13324, Rhopressa™ and Roclatan™ is amenable to scale up and does not require unusual equipment in the manufacturing process. We do not currently operate manufacturing facilities for clinical or commercial production of our product candidates. We currently rely on our third-party manufacturers to produce the active pharmaceutical ingredientAPI and final drug product for our clinical trials. We manage such production with all our vendorsRhopressa® and RocklatanTM and we may rely on a purchase order basis in accordance with applicable master service and supply agreements. We do not have long-term agreements with any of these or any other third-party suppliers to support our clinical trials. Latanoprost, used in the manufacture of Roclatan™, is available in commercial quantities from multiple reputable third-party manufacturers. We intend to procure quantities on a purchase order basismanufacturers for our clinicalcurrent and future product candidates. Our current contract manufacturer produces commercial supply of Rhopressa® and started to manufacture RocklatanTM in 2018 in anticipation of potential FDA approval and commercial production. If any of our existing third-party suppliers should become unavailable to us for any reason, we believe

that there are a number of potential replacements, although we might experience a delay in our ability to obtain alternative suppliers.
With respect to commercial production of our potential products in the future, we plan on outsourcing the production of the active pharmaceutical ingredients. The commercial production of ourthe final drug product manufacturing is ultimately expected to be supported by a combination of internal and outsourced manufacturing. We are currently evaluatingalso in the possibilityprocess of constructing our own manufacturing plant in Ireland. In addition, we have entered into a contractual relationship for the finaladding an additional API contract manufacturer and an additional Rhopressa® drug product manufacturing for commercialization. However, we do not have any current contractual relationships forcontract manufacturer, both of which are expected to begin to supply commercial materials in the first half of 2019. Latanoprost, used in the manufacture of RocklatanTM, is available in commercial production of the active pharmaceutical ingredients.quantities from multiple reputable third-party manufacturers.
We expect to continue to develop drugproduct candidates that can be produced cost-effectively at contract manufacturing facilities. However, should a supplier or manufacturer on which we have relied to produce aRhopressa®, RocklatanTM, Rhokiinsa® or any future product candidate provideprovides us with a faulty product or such product is later recalled, we would likely experience reputational harm, delays and additional costs, each of which could be significant.
In January 2017, we commenced establishment of our own manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, which is expected to produce commercial supplies of Rhopressa® and, if approved, RocklatanTM, Rhokiinsa® and RoclandaTM. Commercial supply from the plant is expected to be available in early 2020. We need to continue to hire and train qualified employees to staff this facility. The management and operation of a pharmaceutical manufacturing facility requires the implementation and development of procedures that are compliant with the quality and other regulations dictated by regulatory authorities in the jurisdictions for which product is produced. Failure to maintain such compliance could cause us to experience delays in production, reputational harm and could negatively affect our commercial operations.

We expect third-party manufacturers to be capable of providing sufficient quantities of Rhopressa® and RocklatanTM to meet our anticipated clinical and commercial demands. If our existing third-party suppliers should become unavailable to us for any reason, we believe that there are a number of potential replacements, although we could experience a delay in our ability to obtain alternative suppliers.

Regulatory Matters
FDA Regulation and Marketing Approval
In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA and related regulations. Drugs are also subject to other federal, state and local statutes and regulations. Failure to comply with the applicable United States regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant to administrative or judicial sanctions and non-approval of product candidates. These sanctions could include the imposition by the FDA or an Institutional Review Board, or IRB,institutional review board (“IRB”) of a clinical hold on trials, the FDA’s refusal to approve pending applications or related supplements, withdrawal of an approval, untitled or warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, restitution, disgorgement, civil penalties or criminal prosecution. Such actions by government agencies could also require us to expend a large amount of resources to respond to the actions. Any agency or judicial enforcement action could have a material adverse effect on us.

15



The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the research, clinical development, manufacture and marketing of pharmaceutical products.
These agencies and other federal, state and local entities regulate research and development activities and the testing, manufacture, quality control, safety, effectiveness, labeling, packaging, storage, distribution, record
keeping, approval, post-approval monitoring, advertising, promotion, sampling and import and export of our products. Our drugs must be approved by the FDA through the NDA process before they may be legally marketed in the United States. See “—The NDA Approval Process”Process below.
The process required by the FDA before drugs may be marketed in the United States generally involves the following:
completion of non-clinical laboratory tests, animal studies and formulation studies conducted according to Good Laboratory Practices or other applicable regulations;
submission of an IND, which allows clinical trials to begin unless FDA objects within 30 days;
adequate and well-controlled human clinical trials to establish the safety and efficacy of the proposed drug for its intended use or uses conducted in accordance with FDA regulations, Good Clinical Practices or GCP,(“GCP”), which are international ethical and scientific quality standards meant to assure the rights, safety and well-being of trial participants are protected and to define the roles of clinical trial sponsors, investigators, administrators, and monitors;
pre-approval inspection of manufacturing facilities and clinical trial sites; and
FDA approval of an NDA, which must occur before a drug can be marketed or sold.
IND and Clinical Trials
Prior to commencing the first clinical trial, an initial IND, which contains the results of preclinical tests along with other information, such as information about product chemistry, manufacturing and controls and a proposed protocol, must be submitted to the FDA. The IND automatically becomes effective 30 days after receipt by the FDA unless the FDA within the 30-day time period raises concerns or questions about the conduct of the clinical trial.trial within the 30-day time period. In such a case, the IND sponsor must resolve any outstanding concerns with the FDA before the clinical trial may begin. A separate submission to the existing IND must be made for each successive clinical trial to be conducted during product development. Further, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that site. Informed consent must also be obtained from each trial subject. Regulatory authorities, including the FDA, an IRB, a data safety monitoring board or the sponsor, may suspend or terminate a clinical trial at any time on various grounds, including a finding that the participants are being exposed to an unacceptable health risk or that the clinical trial is not being conducted in accordance with FDA requirements.
For purposes of NDA approval, human clinical trials are typically conducted in sequential phases that may overlap:
Phase 1—the drug is initially given to healthy human subjects or patients and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. These trials may also provide early evidence on effectiveness. During Phase 1 clinical trials, sufficient information about the investigational drug’s pharmacokinetics and pharmacologic effects may be obtained to permit the design of well- controlledwell-controlled and scientifically valid Phase 2 clinical trials.

Phase 2—trials are conducted in a limited number of patients in the target population to identify possible adverse effects and safety risks, to determineevaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive Phase 3 clinicalregistration trials. Throughout this report, we refer to our initial Phase 2 clinical trials as “Phase 2a clinical trials” and our subsequent Phase 2 clinical trials as “Phase 2b clinical trials.”
Phase 3—when Phase 2 evaluations demonstrate that a dosage range of the product appears effective and has an acceptable safety profile, and provide sufficient information for the design of Phase 3 registration trials, Phase 3 registration trials are undertaken to provide statistically significant evidence of clinical efficacy and to further test for safety in an expanded patient population at multiple clinical trial sites. They are performed after preliminary evidence suggesting effectiveness of the drug has been obtained, and are intended to further evaluate dosage, effectiveness and safety, to establish the overall benefit-risk relationship of the investigational drug and to provide an adequate basis for product labeling and approval by the FDA. In most

16



cases, the FDA requires two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of the drug.
All clinical trials must be conducted in accordance with FDA regulations, GCP requirements and their protocols in order for the data to be considered reliable for regulatory purposes.
In addition, the manufacturer of an investigational drug in a Phase 2 or Phase 3 clinical trial for a serious or life-threatening disease is required to make available, such as by posting on its website, its policy on evaluating and responding to requests for expanded access to such investigational drug.
An investigational drug product that is a combination of two different drugs in the same dosage form must comply with an additional rule that requires that each component make a contribution to the claimed effects of the drug product. This typically requires larger studies that test the drug against each of its components. In addition, typically, if a drug product is intended to treat a chronic disease, as is the case with our products, safety and efficacy data must be gathered over an extended period of time, which can range from six months to three years or more. Government regulation may delay or prevent marketing of product candidates or new drugs for a considerable period of time and impose costly procedures upon our activities.
Disclosure of Clinical Trial Information
Sponsors of clinical trials of FDA-regulated products, including drugs, are required to register and disclose certain clinical trial information. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discussdisclose the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed untilin certain circumstances for up to two years after the new product or new indication being studied has been approved.date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.
The NDA Approval Process
In order to obtain approval to market a drug in the United States, a marketing application must be submitted to the FDA that provides data establishing to the FDA’s satisfaction the safety and effectiveness of the investigational drug for the proposed indication. Each NDA submission requires a substantial user fee payment (currently exceeding $2,350,000$2.5 million for fiscal year 2016)2019) unless a waiver or exemption applies. The application includes all relevant data available from pertinent non-clinical, preclinical and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a product, or from a number of alternative sources, including studies initiated by investigators that meet GCP requirements.
During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at the end of Phase 2, and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice and for the sponsor and the FDA to reach agreement on the next phase of development. Sponsors typically use the end of Phase 2 meetings to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 registration trial that they believe will support approval of the new drug.
Concurrent with clinical trials, companies usually complete additional animal safety studies and must also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing the product in accordance with current Good Manufacturing Practice, or cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and the manufacturer must develop methods for testing the identity, strength, quality and purity of the final

drugs. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf-life.

The results of product development, non-clinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the drug, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the product. An NDA must also contain data to assess the safety and effectiveness of the product for the claimed indication in all relevant pediatric populations. The FDA may grant deferrals for submission of pediatric data or full or partial waivers. The FDA reviews all NDAs submitted to ensure that they are sufficiently complete for substantive review before it files them. It may request additional information rather than accept aan NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA files it. The FDA has 60 days from its receipt of an NDA to conduct an initial review to determine whether the application will be filed based on the agency’s threshold determination that the application is sufficiently complete to permit substantive review. If the NDA submission is filed, the FDA reviews the NDA to determine, among other things, whether the proposed product is safe and effective for its intended use, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, strength, quality and purity. The FDA has agreed to specific performance goals on the review of NDAs and seeks to review standard NDAs in 12 months from

17



submission of the NDA. The review process may be extended by the FDA for three additional months to consider certain late submitted information or information intended to clarify information already provided in the submission. After the FDA completes its initial review of an NDA, it will communicate to the sponsor that the drug will either be approved, or it will issue a complete response letter to communicate that the NDA will not be approved in its current form and inform the sponsor of changes that must be made or additional clinical, non-clinical or manufacturing data that must be received before the application can be approved, with no implication regarding the ultimate approvability of the application or the timing of any such approval, if ever. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. FDA has committed to reviewing such resubmissions in two to six months depending on the type of information included. The FDA may refer applications for novel drug products or drug products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and, if so, under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.
Before approving an NDA, the FDA typically will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA may inspect one or more clinical sites to assure compliance with GCP. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable, it typically will outline the deficiencies and often will request additional testing or information. This may significantly delay further review of the application. If the FDA finds that a clinical site did not conduct the clinical trial in accordance with GCP, the FDA may determine the data generated by the clinical site should be excluded from the primary efficacy analyses provided in the NDA. Additionally, notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.
The FDA may require, or companies may pursue, additional clinical trials after a product is approved. These so-called Phase 4 trials may be made a condition to be satisfied for continuing drug approval. The results of Phase 4 trials canmay confirm the effectiveness of a product candidate and can provide important safety information. In addition, the FDA now has express statutory authority to require sponsors to conduct post-marketing trials to specifically address safety issues identified by the agency. See “—Post-Marketing Requirements”Requirements below.
The FDA also has authority to require a Risk Evaluation and Mitigation Strategy or a REMS,(“REMS”) from manufacturers to ensure that the benefits of a drug outweigh its risks. A sponsor may also voluntarily propose a REMS as part of the NDA submission. The need for a REMS is determined as part of the review of the NDA. Based on statutory standards, elements of a REMS may include “dear doctor letters,” a medication guide, more elaborate targeted educational programs, and in some cases elements to assure safe use or ETASU.(“ETASU”). ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring and the use of patient registries. These elements are negotiated as part of the NDA approval, and in some cases if consensus is not obtained until after the PDUFA review cycle, the approval date may be delayed. Once adopted, REMS are subject to periodic assessment and modification.
Changes to some of the conditions established in an approved application, including changes in indications, labeling, manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the

original application, including relevant pediatric data, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.
Even if a product candidate receives regulatory approval, the approval may be limited to specific disease states, patient populations and dosages, or might contain significant limitations on use in the form of warnings, precautions or contraindications, or in the form of onerous risk management plans, restrictions on distribution, or post-marketing trial requirements. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product or problems the extent or severity of which were unknown may result in restrictions on the product or even complete withdrawal of the product from the market. Delay in obtaining, or failure to obtain, regulatory approval for our products, or obtaining approval but for significantly limited use, would harm our business. In addition, weWe cannot predict what adverse governmental regulations may arise from future U.S. or foreign governmental action.
Adverse Event Reporting
The FDA requires reporting of certain information on side effects and adverse events reported during clinical studies and after marketing approval. Non-compliance with FDA safety reporting requirements may result in FDA regulatory action that may include civil action or criminal penalties. Side effects or adverse events that are reported during clinical trials can delay, impede or prevent marketing approval. Similarly, adverse events that are reported after marketing approval can result in additional limitations being placed on the product's use, require labeling changes, and, potentially, withdrawal or suspension of the product from the market.
The Hatch-Waxman Amendments
Under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments, a portion of a product’s U.S. patent term that was lost during clinical development and regulatory review by the FDA may be

18



restored. The Hatch-Waxman Amendments also provide a process for listing patents pertaining to approved products in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (commonly known as the Orange Book)“Orange Book”) and for a competitor seeking approval of an application that references a product with listed patents to make certifications pertaining to such patents. In addition, the Hatch-Waxman Amendments provide for a statutory protection, known as non-patent exclusivity, against the FDA’s acceptance or approval of certain competitor applications.
Patent Term RestorationExtension
Patent term restorationTerm Extension (“PTE”) in the United States can compensate for lost patent grant time lost during product development and the regulatory review process by returning up to five years of patent life for a patent that covers a new product or its use. This PTE period is generally one-half the time between the effective date of an IND (falling after issuance of the patent) and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application, provided the sponsor acted with diligence. Patent term restorations, however, cannot extendPTEs that can be obtained are for up to five years beyond the remaining termexpiration of athe patent beyond a total ofor 14 years from the date of product approval, and onlywhichever is earlier. Only one patent applicable to an approved drug may be extended and the extension must be applied for prior to expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.
Orange Book Listing
In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent with claims covering the applicant’s product or method of using the product. Upon approval of a drug, each of the patents listedidentified in the application for the drug are then published in the FDA’s Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application or ANDA.(“ANDA”). An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been shown to be bioequivalent to the listed drug. Other than the requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, preclinical or clinical tests to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug and can often be substituted by pharmacists under prescriptions written for the original listed drug.
The ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by the new product. The ANDA applicant may also elect to submit a Section VIII statement certifying that its proposed ANDA labeling does not contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. If the applicant does not challenge the

listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.
A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been filed with and accepted by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit or a decision in the infringement case that is favorable to the ANDA applicant.
An applicant submitting an NDA under Section 505(b)(2) of the FDCA, which permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference, is required to certify to the FDA regarding any patents listed in the Orange Book for the approved product it references to the same extent that an ANDA applicant would.
Market Exclusivity
Market exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity or NCE.(“NCE”). A drug is entitled to NCE exclusivity if it contains a drug substance no active moiety of which has been previously approved by the FDA. This means that, in the case of a fixed-dosedfixed-dose combination product, the FDA makes the NCE exclusivity determination for each drug substance in the drug product and not for the drug product as a whole. During the exclusivity period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted

19



by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a Paragraph IV certification. TheFor a drug that has been previously approved by the FDA, the FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the new conditions associated with the new clinical investigationsof use and does not prohibit the FDA from approving ANDAs for drugs for the original conditions of use, such as the originally approved indication. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA; however, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the non-clinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.
Post-Marketing Requirements
Following approval of a new product, a pharmaceutical company and the approved product are subject to continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse experiences with the product, providing the regulatory authorities with updated safety and efficacy information, product sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug’s approved labeling (known as “off-label use”), limitations on industry-sponsored scientific and educational activities and requirements for promotional activities involving the internet. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses. Modifications or enhancements to the product or its labeling or changes of the site of manufacture are often subject to the approval of the FDA and other regulators, who may or may not grant approval or may include in a lengthy review process.
Advertising
Prescription drug advertising is subject to federal, state and foreign regulations. In the United States, the FDA regulates prescription drug promotion, including direct-to-consumer advertising. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Any distribution of prescription drug products and pharmaceutical samples must comply with the U.S. Prescription Drug Marketing Act or the PDMA,(“PDMA”), a part of the FDCA. In addition, Title II of the Federal Drug Quality and Security Act of 2013, known as the Drug Supply Chain Security Act or the DSCSA, has imposed new “track and trace” requirements on the distribution of prescription drug products by manufacturers, distributors, and other entities in the drug supply chain. These requirements are being phased in over a ten-year period. Unless the products were packaged prior to November 27, 2018, the DSCSA requires product identifiers (i.e., serialization) on prescription drug products in order to establish an electronic interoperable prescription product system to identify and trace certain prescription drugs

distributed in the United States. The DSCSA replaced the prior drug “pedigree” requirements under the PDMA, and preempts existing state drug pedigree laws and regulations. The DSCSA also establishes new requirements for the licensing of wholesale distributors and third-party logistic providers. These licensing requirements preempt states from imposing licensing requirements that are inconsistent with, less stringent than, directly related to, or otherwise encompassed by standards established by FDA pursuant to the DSCSA. Until FDA promulgates regulations to address the DSCSA’s new national licensing standard, current state licensing requirements typically remain in effect.
Manufacturing
In the United States, once a product is approved, its manufacture is subject to comprehensive and continuing regulation by the FDA. The FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMP. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with cGMP regulations. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. These regulations also impose certain organizational, procedural and documentation requirements with respect to manufacturing and quality assurance activities. We currently rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with cGMP regulations. NDA holders using contract manufacturers, laboratories or packagers are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These firms and, where applicable, their suppliers are subject to inspections by the FDA at any time, and the discovery of violative conditions, including failure to conform to cGMP, could result in enforcement actions that interrupt the operation of any such product or may result in restrictions on a product, manufacturer, or holder of an approved NDA, including, among other things, recall or withdrawal of the product from the market.
In addition, the manufacturer and/or sponsorapplicant under an approved NDA areis subject to an annual program fee (replacing the old product and establishment fees,fees), currently exceeding $100,000$300,000 per prescription drug product and $550,000 per establishment for fiscal year 2016. These fees are typically increased annually.2018.
Post-Approval Testing
The FDA also may require post-marketing testing, also known as Phase 4 testing, REMS to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, untitled or warning letters from the FDA, mandated corrective advertising or communications with doctors, withdrawal of approval, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our products under development.

Reimbursement, Anti-Kickback and False Claims Laws and Other Regulatory Matters
In the United States, the research, manufacturing, distribution, sale and promotion of drug products and medical devices are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare & Medicaid Services (“CMS”), other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, state Attorneys General and other state and local government agencies. For example, sales, marketing and scientific/educational grant programs must comply with the Federal Anti-Kickback Statute, the False Claims Act, as amended, the privacy regulations promulgated under the Health Insurance Portability and Accountability Act (HIPAA)of 1996 (“HIPAA”), as amended, and similar state laws. Pricing and rebate programs must be considered in price reports in order to comply with the Medicaid Drug Rebate Program requirements of the Omnibus Budget Reconciliation Act of 1990, as amended, and the Veterans Health Care Act of 1992, as amended. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. All of these activities are also potentially subject to federal and state consumer protection and unfair competition laws.
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 or the MMA,(“MMA”), established the Medicare Part D program to provide a voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may

enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, partPart D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a partPart D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand for products for which we receive regulatory approval. However, any negotiated prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payorspayers often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-government payors.payers.
The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.
The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness of different treatments for the same illness. A plan for the research will be developed by the Department of Health and Human Services, the Agency for Healthcare Research and Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures will be made to Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors,payers, it is not clear what effect, if any, the research will have on the sales of our product candidate,products, if any such productproducts or the condition that it is intended to treat is the subject of a trial. It is also possible that comparative effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of our product candidate.products. If third-party payorspayers do not consider our products to be cost-effective compared to other available therapies, they may not cover our products after approval as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.
In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union (“EU”) provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our potential products. Historically, products launched in the European UnionEU do not follow price structures of the United States and generally tend to be significantly lower.
As noted above, in the United States, we are subject to complex laws and regulations pertaining to healthcare “fraud and abuse,” including, but not limited to, the Federal Anti-Kickback Statute, the Federal False Claims Act, and other state and federal laws and regulations. The Federal Anti-Kickback Statute makes it illegal for any person, including a prescription drug manufacturer (or a party acting on its behalf) to knowingly and willfully solicit, receive, offer, or pay any remuneration that is

21



intended to induce the referral of business, including the purchase, order, or prescription of a particular drug, for which payment may be made under a federal healthcare program, such as Medicare or Medicaid. Violations of this law are punishable by up to five years in prison, criminal fines, administrative civil money penalties, and exclusion from participation in federal healthcare programs. In addition, many states have adopted laws similar to the Federal Anti-Kickback Statute. Some of these state prohibitions apply to the referral of patients for healthcare services reimbursed by any insurer, not just federal healthcare programs such as Medicare and Medicaid. Due to the breadth of these federal and state anti-kickback laws, the absence of guidance in the form of regulations or court decisions, and the potential for additional legal or regulatory change in this area, it is possible that our future sales and marketing practices and/or our future relationships with eye-care professionals might be challenged under anti-kickback laws, which could harm us. Because we intend to commercialize products that could be reimbursed under a federal healthcare program and other governmental healthcare programs, we plan to develophave developed a comprehensive compliance program that establishes internal controls to facilitate adherence to the rules and program requirements to which we will or may become subject.
The Federal False Claims Act prohibits anyone from knowingly presenting, or causing to be presented, for payment to federal programs (including Medicare and Medicaid) claims for items or services, including drugs, that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services. Although we would not submit claims directly to payors,payers, manufacturers can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. In addition, our future activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal,

state and third-party reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under this law. For example, pharmaceutical companies have been found liable under the Federal False Claims Act in connection with their off-label promotion of drugs. Penalties for a False Claims Act violation include three times the actual damages sustained by the government, plus mandatory civil penalties of between $5,500$10,000 and $11,000$25,000 for each separate false claim, the potential for exclusion from participation in federal healthcare programs, and, although the Federal False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes. If the government were to allege that we were, or convict us of, violating these false claims laws, we could be subject to a substantial fine and may suffer a decline in our stock price. In addition, private individuals have the ability to bring actions under the Federal False Claims Act and certain states have enacted laws modeled after the Federal False Claims Act.
There are also an increasing number of state laws thatwith requirements for manufacturers and/or marketers of pharmaceutical products. Some states require manufacturersthe reporting of expenses relating to make reportsthe marketing and promotion of drug products and the reporting of gifts and payments to individual healthcare practitioners in these states. Other states onprohibit various marketing-related activities, such as the provision of certain kinds of gifts or meals. Still other states require the reporting of certain pricing information, including information pertaining to and justification of price increases, or prohibit prescription drug price gouging. In addition, states such as California, Connecticut, Nevada, and Massachusetts require pharmaceutical companies to implement compliance programs and/or marketing information.codes. Many of these laws contain ambiguities as to what is required to comply with the laws. In addition, as discussed below, beginning in 2013,“—Patient Protection and Affordable Care Act” below, a similar federal requirement will requirerequires manufacturers to track and report to the federal government certain payments made to physicians and teaching hospitals made in the previous calendar year. These laws may affect our sales, marketing and other promotional activities by imposing administrative and compliance burdens on us. In addition, given the lack of clarity with respect to these laws and their implementation, our reporting actions could be subject to the penalty provisions of the pertinent state, and soon federal, authorities.
Numerous U.S. federal and state laws, including state security breach notification laws, state health information privacy laws and U.S. federal and state consumer protection laws, govern the collection, use and disclosure of personal information. Other countries also have, or are developing, laws governing the collection, use and transmission of personal information. In addition, most healthcare providers who are expected to prescribe our products and from whom we obtain patient health information, are subject to privacy and security requirements under HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”) and its implementing regulations, which imposes requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates,” such as independent contractors or agents of covered entities that receive or obtain protected health information with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business associates. In addition, HITECH also gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing these actions. As a result of HIPAA, we could be subject to criminal penalties if we obtain and/or disclose individually identifiable health information from a HIPAA-covered entity, including healthcare providers, in a manner that is not authorized or permitted by HIPAA. In addition, many U.S. states and foreign governments have enacted comparable laws addressing the privacy and security of health information, such as the General Data Protection Regulation (the “GDPR”) enacted by the EU, some of which are more stringent than HIPAA. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to disrupt our operations, including recently enacted laws in a majority of states requiring security breach notification. If there are any violations of these laws, we could face significant administrative and monetary sanctions as well as reputational damage, which may have a material adverse effect on our business.
The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, including government contracts.
Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by required,requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.
Patient Protection
Government Programs for Marketed Drugs
Medicaid, the 340B Drug Pricing Program, and Affordable Care ActMedicare
In MarchFederal law requires that a pharmaceutical manufacturer, as a condition of having its products receive federal reimbursement under Medicaid and Medicare Part B, must pay rebates to state Medicaid programs for all units of its covered outpatient drugs dispensed to Medicaid beneficiaries and paid for by a state Medicaid program under either a fee-for-service arrangement or through a managed care organization. This federal requirement is effectuated through a Medicaid drug rebate agreement between the manufacturer and the Secretary of Health and Human Services. CMS administers the Medicaid drug rebate agreements, which provide, among other things, that the drug manufacturer will pay rebates to each state Medicaid agency on a quarterly basis and report certain price information on a monthly and quarterly basis. The rebates are based on prices reported to CMS by manufacturers for their covered outpatient drugs. For innovator products, that is, drugs that are marketed under approved NDAs, the basic rebate amount is the greater of 23.1% of the average manufacturer price (“AMP”) for the quarter or the difference between such AMP and the best price for that same quarter. The AMP is the weighted average of prices paid to the manufacturer (1) directly by retail community pharmacies and (2) by wholesalers for drugs distributed to retail community pharmacies. The best price is essentially the lowest price available to non-governmental entities. Innovator products are also subject to an additional rebate that is based on the amount, if any, by which the product’s current AMP has increased over the baseline AMP, which is the AMP for the first full quarter after launch, adjusted for inflation. For non-innovator products, generally generic drugs marketed under approved abbreviated new drug applications, the basic rebate amount is 13% of the AMP for the quarter. Until amendments to the statute were enacted, this was the only rebate applicable to non-innovator products. However, as a result of a November 2015 amendment, non-innovator products are subject to an additional rebate. The additional rebate is similar to that discussed above for innovator products, except that the baseline AMP quarter is the fifth full quarter after launch (for non-innovator multiple source drugs launched on April 1, 2013 or later) or the third quarter of 2014 (for those launched before April 1, 2013). The statutory definition of AMP was amended in 2010 by the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, PPACA)“PPACA”). In February 2016, CMS published a final rule to further define AMP and provide clarification on other parts of the rebate program.
The terms of participation in the Medicaid drug rebate program impose an obligation to correct the prices reported in previous quarters, as may be necessary. Any such corrections could result in additional or lesser rebate liability, depending on the direction of the correction. In addition to retroactive rebates, if a manufacturer were found to have knowingly submitted false information to the government, federal law provides for civil monetary penalties for failing to provide required information, late submission of required information, and false information.
A manufacturer must also participate in a federal program known as the 340B drug pricing program in order for federal funds to be available to pay for the manufacturer’s drugs under Medicaid and Medicare Part B. Under this program, the participating manufacturer agrees to charge certain safety net healthcare providers no more than an established discounted price for its covered outpatient drugs. The formula for determining the discounted price is defined by statute and is based on the AMP and the unit rebate amount as calculated under the Medicaid drug rebate program, discussed above. Manufacturers are required to report pricing information to the Health Resources and Services Administration (“HRSA”) on a quarterly basis effective the first quarter of 2019. HRSA has also issued regulations relating to the calculation of the ceiling price as well as imposition of civil monetary penalties for each instance of knowingly and intentionally overcharging a 340B covered entity.
Federal law also requires that manufacturers report data on a quarterly basis to CMS regarding the pricing of drugs that are separately reimbursable under Medicare Part B. These are generally drugs, such as injectable products, that are administered “incident to” a physician service and are not generally self-administered. The pricing information submitted by manufacturers is the basis for reimbursement to physicians and suppliers for drugs covered under Medicare Part B. As with the Medicaid drug rebate program, federal law provides for civil monetary penalties for failing to provide required information, late submission of required information, and false information.
Medicare Part D provides prescription drug benefits for seniors and people with disabilities. Medicare Part D beneficiaries have a gap in their coverage (between the initial coverage limit and the point at which catastrophic coverage begins) where Medicare does not cover their prescription drug costs, known as the coverage gap. However, by 2020, Medicare Part D beneficiaries will pay 25% of drug costs after they reach the initial coverage limit - the same percentage they were responsible for before they reached that limit - thereby closing the coverage gap. The cost of closing the coverage gap is being borne by innovator companies and the government through subsidies. Beginning in 2011, each manufacturer of drugs approved under NDAs was required to enter into a Medicare Part D coverage gap discount agreement and provide a 50% discount on those drugs dispensed to Medicare beneficiaries in the coverage gap, in order for its drugs to be reimbursed by Medicare Part D. The Bipartisan Budget Act of 2018 increased the manufacturer’s subsidy under this program from 50% to 70% of the negotiated price, beginning in 2019.

Federal Contracting/Pricing Requirements
Manufacturers are also required to make their covered drugs, which are generally drugs approved under NDAs, available to authorized users of the Federal Supply Schedule (“FSS”) of the General Services Administration. The law also requires manufacturers to offer deeply discounted FSS contract pricing for purchases of their covered drugs by the Department of Veterans Affairs, the Department of Defense (“DoD”), the Coast Guard, and the Public Health Service (including the Indian Health Service) in order for federal funding to be available for reimbursement or purchase of the manufacturer’s drugs under certain federal programs. FSS pricing to those four federal agencies for covered drugs must be no more than the Federal Ceiling Price (“FCP”), which is at least 24% below the Non-Federal Average Manufacturer Price (“Non-FAMP”) for the prior year. The Non-FAMP is the average price for covered drugs sold to wholesalers or other middlemen, net of any price reductions.
The accuracy of a manufacturer’s reported Non-FAMPs, FCPs, or FSS contract prices may be audited by the government. Among the remedies available to the government for inaccuracies is recoupment of any overcharges to the four specified federal agencies based on those inaccuracies. If a manufacturer were found to have knowingly reported false prices, in addition to other penalties available to the government, the law provides for civil monetary penalties of $100,000 per incorrect item. Finally, manufacturers are required to disclose in FSS contract proposals all commercial pricing that is equal to or less than the proposed FSS pricing, and subsequent to award of an FSS contract, manufacturers are required to monitor certain commercial price reductions and extend commensurate price reductions to the government, under the terms of the FSS contract Price Reductions Clause. Among the remedies available to the government for any failure to properly disclose commercial pricing and/or to extend FSS contract price reductions is recoupment of any FSS overcharges that may result from such omissions.
Tricare Retail Pharmacy Network Program
The DoD provides pharmacy benefits to current and retired military service members and their families through the Tricare healthcare program. When a Tricare beneficiary obtains a prescription drug through a retail pharmacy, the DoD reimburses the pharmacy at the retail price for the drug rather than procuring it from the manufacturer at the discounted FCP discussed above. In order for the DoD to realize discounted prices for covered drugs (generally drugs approved under NDAs), federal law requires manufacturers to pay refunds on utilization of their covered drugs sold to Tricare beneficiaries through retail pharmacies in DoD’s Tricare network. These refunds are generally the difference between the Non-FAMP and the FCP and are due on a quarterly basis. Absent an agreement from the manufacturer to provide such refunds, DoD will designate the manufacturer’s products as Tier 3 (non-formulary) and require that beneficiaries obtain prior authorization in order for the products to be dispensed at a Tricare retail network pharmacy. However, refunds are due whether or not the manufacturer has entered into such an agreement.
Branded Pharmaceutical Fee
A branded pharmaceutical fee is imposed on manufacturers and importers of branded prescription drugs, generally drugs approved under NDAs. In each year between 2011 and 2018, the aggregate fee for all such manufacturers will range from $2.5 billion to $4.1 billion, and then will remain at $2.8 billion in 2019 and subsequent years. This annual fee is apportioned among the participating companies based on each company’s sales of qualifying products to or utilization by certain U.S. government programs during the preceding calendar year. The fee became effective January 1, 2011, and is not deductible for U.S. federal income tax purposes. Utilization of generic drugs, generally drugs approved under ANDAs, is not included in a manufacturer’s sales used to calculate its portion of the fee.
Patient Protection and Affordable Care Act
In March 2010, the PPACA was enacted, which includes measures that have or will significantly change the way healthcare is financed by both governmental and private insurers. Among the provisions of PPACA of greatest importance to the pharmaceutical industry are the following:
 
The Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of the Department of Health and Human Services a condition for states to receive federal matching funds for the manufacturer’s covered outpatient drugs furnished to Medicaid patients. EffectiveAs discussed above, effective in 2010, PPACA made several changes to the Medicaid Drug Rebate Program,

22



including increasing pharmaceutical manufacturers’ rebate liability by raising the minimum basic Medicaid rebate on most branded prescription drugs and biologic agents to 23.1% of AMP and adding a new rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP. PPACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid managed care utilization as of 2010 and by beginning in 2011, expanding the population potentially eligible for Medicaid drug benefits. The Centers for Medicare & Medicaid Services, or CMS expanded Medicaid rebate liability to the territories of the United States as well, effective April 1, 2017.2020. In addition, PPACA provides

for the public availability of retail survey prices and certain weighted average AMPs under the Medicaid program. The implementation of this requirement by the CMS, beginning in April 2016, may also provideprovided for the public availability of pharmacy acquisition of cost data, which could negatively impact our sales.
In order for a pharmaceutical product to receive federal reimbursement under the Medicare Part B and Medicaid programs or to be sold directly to U.S. government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer. Effective in 2010, PPACA expanded the types of entities eligible to receive discounted 340B pricing, although, under the current state of the law, with the exception of children’s hospitals, these newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs when used for the orphan indication. In addition, as 340B drug pricing is determined based on AMP and Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described above could cause the required 340B discount to increase.
Effective in 2011, PPACA imposed a requirement on manufacturers of branded drugs and biologic agents to provide a 50% discount off the negotiated price of branded drugs dispensed to Medicare Part D patients in the coverage gap (i.e., “donut hole”). The Bipartisan Budget Act of 2018 increased the manufacturer’s subsidy under this program from 50% to 70% of the negotiated price, beginning in 2019.
Effective in 2011, PPACA imposed an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, apportioned among these entities according to their market share in certain government healthcare programs, although this fee would not apply to sales of certain products approved exclusively for orphan indications.
PPACA requires pharmaceutical manufacturers to track certain financial arrangements with physicians and teaching hospitals, including any “transfer of value” made or distributed to such entities, as well as any investment interests held by physicians and their immediate family members. Manufacturers wereEffective January 1, 2022, we will also be required to track this information beginning in 2013,report on transfers of value to, among others, physician assistants and the first reports were due in 2014.nurse practitioners or clinical nurse specialists. The information reported each year is made publicly available on a searchable website.
As of 2010, a new Patient-Centered Outcomes Research Institute was established pursuant to PPACA to oversee, identify priorities in and conduct comparative clinical effectiveness research, along with funding for such research. The research conducted by the Patient-Centered Outcomes Research Institute may affect the market for certain pharmaceutical products.
PPACA created the Independent Payment Advisory Board, which has the authority to recommend certain changes to the Medicare program to reduce expenditures by the program that could result in reduced payments for prescription drugs. Under certain circumstances, these recommendations will become law unless Congress enacts legislation that will achieve the same or greater Medicare cost savings.
PPACA established the Center for Medicare and Medicaid Innovation within CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending. Funding has been allocated to support the mission of the Center for Medicare and Medicaid Innovation from 2011 to 2019.
Many ofThere have been ongoing discussions within the detailsU.S. federal government regarding the implementationfuture of PPACA. There is uncertainty with respect to the impact these changes, if any, may have, and impact of PPACA are yetany changes likely will take time to be determined, and at this time, it remains unclear the full effect that PPACA would have on our business.

European Union

European Union Drug Development
In the European Union,EU, our products and product candidates will also be subject to extensive regulatory requirements. Regulatory laws for pharmaceuticals are largely harmonized throughout the EU, so that applicable EU law is most significant and national laws have less importance. As in the United States, medicinal products can only be marketed if a marketing authorization from the competent regulatory agencies has been obtained, and the various phases of preclinical and clinical research in the European UnionEU are subject to significant regulatory controls. Phases 1 to 3 of clinical trials in humans are comparable to those regulated in the United States, and GCP requirements in the EU for these studies follow internationally accepted standards.
Although the EU Clinical Trials Directive 2001/20/EC has sought to harmonize the EU clinical trial regulatory framework for pharmaceuticals by setting out common rules for the control and authorization of clinical trials in the European Union,EU, the EU Member States have transposed and applied the provisions of the Directive differently. This has led to significant variations in the member state regimes. Under the current regime, before a clinical trial can be initiated it must be approved in each of the EU countries where the trial is to be conducted by two distinct bodies: the National Competent Authority or NCA,(“NCA”) and one or more Ethics Committees or ECs. In addition, all(“ECs”). All suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial must be reported to the NCA and ECs of the Member State where they occurred.
The EU All clinical trials legislation is currently undergoing a revision process mainly aimed at makingwill have to conform to current GCP guidelines issued by the EU and the International Council on Harmonisation of Technical

Requirements for Registration of Pharmaceuticals for Human Use, in particular when the results of such trials are being used in marketing authorization procedures, and audits by EU inspectors on regulatory conformance of such clinical trials are likely.
In 2014, the new EU Clinical Trial Regulation 546/2014 was enacted. When it becomes applicable (currently expected beginning in 2020), it will govern all newly-commenced clinical trials. The new Regulation aims to make more uniform and streamliningstreamline the clinical trials authorization process, simplifying adverse event reporting procedures, improvingensure consistent rules for conducting clinical trials throughout the supervisionEU, increase the efficiency of clinical trials, and increasingincrease the transparency of authorization, conduct and results of clinical trials. All currently conducted clinical trials remain subjected to the Clinical Trials Directive of 2001.

Generally, in the European Economic Area (“EEA”), for every product candidate, a pediatric investigation plan (“PIP”) will have to be submitted and approval be obtained, in addition to clinical trials conducted in adults. The clinical studies that sponsoring companies must carry out on children are to be set out in detail in the PIP. In most cases, the PIP will become a commitment when applying for a marketing authorization for a product candidate. A PIP may entail significant cost.
European Union Drug Review Approval
In the European Economic Area, or EEA, which is currently comprised of the 2728 Member States of the European UnionEU plus Norway, Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization or MA.(“MA”) which is comparable to an NDA in the United States. There are two types of marketing authorizations:authorizations in the EEA: the Community MA, which is issued by the European Commission through the Centralized Procedure based on the opinion of the Committee for Medicinal Products for Human Use or CHMP,(“CHMP”), a body of the EMA, and which is valid throughout the entire territory of the EEA; and the National MA, which is issued by the competent authorities of theeach Member StatesState of the EEA and only authorizedauthorizes marketing in that Member State’s national territory and not in the EEA as a whole.
The Centralized Procedure is mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal products and medicinal products containing a new active substance indicated for the treatment of AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and viral diseases. The Centralized Procedure is optional for products containing a new active substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the European Union.EU. The National MA is for products not falling within the mandatory scope of the Centralized Procedure. Where a product has already been authorized for marketing in a Member State of the EEA, this National MA can be recognized in another Member StatesState through the Mutual Recognition Procedure. If the product has not received a National MA in any Member State at the time of application, it can be approved simultaneously in various Member States through the Decentralized Procedure. Under the Decentralized Procedure an identical dossier is submitted to the competent authorities of each of the Member States in which the MA is sought, one of which is selected by the applicant as the Reference Member state, or RMS.State (“RMS”). If the RMS proposes to authorize the product, and the other Member States do not raise objections, the product is granted a national MA in all the Member States where the authorization was sought. Before granting the MA, the EMA or the competent authorities of the Member States of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy.
Our current EU application seeks to obtain a Centralized MA for Rhokiinsa®. We have submitted our application directly to the EMA, which has accepted our application. The EMA is responsible for the validation and scientific evaluation of the application but the European Commission will decide upon our application. The EMA's CHMP will carry out a scientific assessment of the application and will give a recommendation on whether the medicine should be authorized or not. A favorable opinion is accompanied by a draft summary of the product's characteristics, the package leaflet and the proposed text for the packaging.
The time limit for the evaluation procedure is 210 days, subject to extensions if additional questions need to be addressed. Within 15 days of the adoption, the EMA will forward its opinion to the European Commission to start the decision-making phase. Within 15 days a draft implementing decision is sent by the Commission to the Standing Committee on Medicinal Products for Human Use, allowing for its scrutiny by EU countries. These have 15 days to return their linguistic comments, and 22 days for substantial ones. Once a favorable opinion is reached, the draft decision is adopted via an empowerment procedure. The adoption of the decision should take place within 67 days of the opinion of the EMA. The Commission's Secretariat-General then notifies the marketing authorization holder of the decision. The decision is subsequently published in the Community Register.
Marketing authorizations are initially valid for five years. Applications for renewal must be made to the EMA at least six months before this five-year period expires.

Files Required for Obtaining an EU Marketing Authorization
Similar to the United States, applications for MAs in the EU must be supported by an extensive dossier that shows the product candidate has the required quality, efficacy and safety suitable for the intended use, and additional administrative documents. The content and format of the dossier must follow the so-called Common Technical Document (“CTD”) format. Amongst other things, the applicant must submit all relevant data from pharmaceutical, pre-clinical and clinical trials, and all relevant information as regards the composition, quality and manufacturing process of the product. These requirements are laid down in applicable EU legislation and very detailed EMA guidelines.
In the course of the MAA process, an inspection of the veracity and the compliance of the clinical trials that form the basis of the MAA may be conducted by EU inspectors. If it turns out that a clinical trial does not meet GCP and other applicable regulatory standards, it may not serve as a basis for proving efficacy and safety of the product at issue.
Also, the manufacturing sites for the active ingredients of the product candidate may be inspected by the EU in order to establish that the manufacturing indeed complies with cGMP standards.
Applicants are responsible for ensuring the safety profile of their medicine is adequately characterized at the time of submitting their MAA. Applicants are required to submit a risk management plan as part of their MAA. Risk management plans describe existing knowledge on the safety of a medicine and future pharmacovigilance activities designed to further study or monitor the product's safety. Part of that plan will be that a qualified person responsible for pharmacovigilance is being retained.
Post-approval Obligations of an MA Holder in the EU
Even after approval of a product candidate by the European Commission, an MA holder will face various ongoing actions and obligations and must ensure that it has a suitable organization in place that is able to meet these obligations.
Reportable suspected adverse events must be reported to competent authorities via EudraVigilance, a centralized European information system of suspected adverse reactions to medicines. EudraVigilance will re-route the case safety reports to EU member states. The EMA will make the reports of individual cases of suspected adverse reactions also available to the WHO Uppsala Monitoring Centre. Patients and healthcare professionals will continue to report adverse reactions to national competent authorities.
For public health reasons, the EMA may require the MA holder to provide additional data post-authorization, as necessary to provide additional data about the safety and, in certain cases, the efficacy or quality of authorized medicinal products.
The EMA is responsible for harmonizing and coordinating pharmacovigilance inspections at EU level, which involves, among others:
Preparing a risk-based program of routine pharmacovigilance inspections in relation to centrally authorised products.
Preparing and developing guidance on pharmacovigilance inspections.
Coordinating advice on the interpretation of pharmacovigilance requirements and related technical issues.
The EMA is also responsible for coordinating inspections to verify compliance with cGMP, GCP, good laboratory practice and good pharmacovigilance practice, and any other aspects of the supervision of authorized medicinal products.
Member States and the Commission must inform other member states, the EMA and the Commission if concerns result from the evaluation of data from pharmacovigilance activities. This may result in the suspension or revocation of the marketing authorization.
Member states have systems in place which aim at preventing dangerous medicinal products from reaching the patient, and cover the receipt and handling of notifications of suspected falsified medicines or quality defects. Rapid alerts must be sent to all member states and a recall may be initiated if such medicines have already reached patients.
An MA holder must:
Continuously operate a pharmacovigilance system, part of which requires a permanently and continuously available appropriately qualified person responsible for pharmacovigilance.

Establish a risk management system, take account of scientific and technical progress and adapt accordingly, and continuously provide the competent authorities with information which might involve amendment of its marketing authorization.
Inform the competent authorities of positive and negative results in clinical trials or studies and any defects, and on request have at its disposal details regarding, for example, the volume of sales.
Ensure that a package information leaflet is made available on request from patients' organizations, in formats appropriate for the blind and partially-sighted.
Inform the EMA of changes related to the placement of the medicinal product on the market, for example withdrawal or suspension.
Data Exclusivity and Similar Protection in the EU
An innovator company enjoys a period of "data exclusivity" during which its preclinical and clinical trials data may not be referenced in the regulatory filings of another company (typically a generic company) for the same drug substance.
The period of data exclusivity in Europe has been harmonized as eight years from the date of first authorization in Europe. There is an additional period of two years of "market exclusivity". This is the period of time during which a generic company may not market an equivalent generic version of the originator's pharmaceutical product (although their application for authorization may be processed during this period, such that they are in a position to market their product on the expiry of this additional two-year period).
After that period of a total of 10 years, generic companies can market their “essentially similar” products by referencing the innovator’s data, unless the innovator product qualifies for a further one year of exclusivity. This additional one year may be obtained if the innovator company is granted an MA for a significant new indication for the relevant medicinal product within the first eight years of its marketing. In such a situation, the generic companies can only market their copy products after 11 years from the grant of the innovator company's initial MA.
In addition, the innovator company may be eligible to receive a Supplementary Protection Certificate (“SPC”). This is an intellectual property right that serves as an extension to a patent right, comparable to a PTE in the U.S. SPCs aim to offset the loss of patent protection for pharmaceutical products that occurs due to the compulsory lengthy testing and clinical trials these products require prior to obtaining regulatory marketing approval.
An SPC can extend an eligible patent right for a maximum of five years. An additional six-month extension is available in accordance with Regulation (EC) No 1901/2006 if the SPC relates to a medicinal product for children for which data has been submitted according to a PIP, as outlined above.
Reimbursement in the EU
The EU does not have a centralized healthcare system. Healthcare is provided through very different systems at the national level. This jurisdictional divide may lead to delayed or restricted patient access. Generally, the reimbursement prices must be negotiated with national healthcare carriers on a state-by-state process.
EU and national laws impose a number of restrictions on pricing. Directive 89/105/EEC relating to the transparency of measures regulating the prices of medicinal products (“Transparency Directive”) aims to ensure the transparency of national pricing and reimbursement. It sets procedural requirements to help monitor national decisions and their compatibility with pharmaceutical trade in the EU internal market. For example, member states must ensure that decisions on prices are made within a certain timeframe and communicated to the applicant with a statement of reason based on objective and verifiable criteria. Member states must also ensure that such decisions are open to judicial review.
Another important restriction on pricing is Article 102 of the Treaty on the Functioning of the European Union (“TFEU”), which prohibits dominant pharmaceutical companies from abusing this dominance in their relevant markets.
EU Privacy Laws
The GDPR came into effect in the European Union on May 25, 2018, and has changed the way that personal data can be held and processed. Non-compliance can lead to substantial fines, amounting to up to 4% of annual global revenue or €20 million, whichever is greater.

The GDPR expands and formalizes many rights that existed under former laws. It also requires that organizations inventory their data and document the legal basis for processing personal information. Further, the GDPR provides EU data subjects with rights they may exercise in connection with their data such as the “right to be forgotten”.
Generally, personal data of third parties must only be held and used by a company (the “Data Controller”) when covered by an informed consent of the person concerned, or by a legitimate and vital interest, as defined in the GDPR. Any consent must be informed, freely given and specific, and, if applicable, also include the right to transfer personal data to a country outside of the EU. The Data Controller is responsible for GDPR compliance, but can outsource certain tasks to third parties, so-called “Data Processors”. Affected third parties must be informed in some detail on the storage and use of their data, e.g. as clinical trial subjects, or as prescribers, and have the right to deny their consent.
It is important for companies to ensure they have a nominated data protection officer. They must also brief and train their staff, so they are aware and aligned. Companies should keep records of their approach to GDPR and how they have prepared for it. Preparation should also extend to a response in the event of an access request or complaint from a data subject, or with regards to a GDPR breach.
Brexit
Unless otherwise agreed with the other member states of the EU, the United Kingdom will leave the EU in March 2019 (“Brexit”). As one of the Brexit consequences, the EMA will relocate from London to Amsterdam. It is unclear what impacts Brexit will have with respect to the cross-border acknowledgment of clinical trial results and MAs; however, it is possible that a separate marketing application and approval will be required to market a product in the United Kingdom, and that significant delays will occur before the product can be marketed in the United Kingdom. Likewise, a no deal Brexit could cause the United Kingdom to be treated as a third country under GDPR requiring use of GDPR sanctioned mechanisms for data transfers.
Japan
Right of Reference
In Japan, clinical trial data collected for obtaining an approval in foreign countries can be used for obtaining an approval for a drug in accordance with the requirements stipulated in the notification by Ministry of Health, Labor and Welfare (the “MHLW”). The collection of such clinical data and drafting of the submission must meet the requirements under the normal Japanese regulations (Article 43 of the Enforcement Regulations of Pharmaceuticals and Medical Devices Law). The clinical trial data are required to include (i) pharmacodynamics, dose response, efficacy and safety in the foreign countries, (ii) clinical test data clearly exhibiting dose response, efficacy and safety (planned and performed in accordance with Japan rules, such as the Ministerial Ordinance on Good Clinical Practice for Drugs, and GCP; well-managed and using proper test controls; and using proper endpoints, and (iii) pharmacodynamics characteristic in the Japanese population. Further, the MHLW usually requests that a company submit bridging data from testing that is performed in Japan so that the clinical test data in foreign countries are demonstrated to be able to be generalized to the Japanese population. Generally, when the bridging data demonstrate that the dose response, efficacy and safety in Japan are similar to those in the foreign countries, the MHLW recognizes that the test results in the foreign countries can be generalized to the Japanese population. When the dose of the Japanese population in the bridging data is different from that of the test in the foreign countries, the MHLW will request that a company submit pharmacodynamics test results. When the number of samples in the bridging study or studies is limited, the MHLW will request that a company further submit test data demonstrating safety. When the bridging data cannot demonstrate efficacy and safety, the MHLW will request that a company submit clinical test results for the Japanese population.
Obtaining Approval
In practice, there are three basic ways for a non-Japanese company to obtain approval for pharmaceuticals manufactured overseas:
Option 1—establish a Japanese corporation that obtains the necessary approvals and licenses. This provides the most durable presence in Japan. It also entails high initial time and expense (including hiring staff) and must be done in compliance with the provisions of the Pharmaceuticals and Medical Devices Law.
Option 2—designate an existing Japanese company to obtain the necessary approvals and licenses. The manufacturing/sales approval for the drug will be registered in the Japanese company's name. This can raise potential problems if the overseas company does not strictly control the Japanese approval holder.
Option 3—use the designated marketing approval holder (“DMAH”) system under Article 19-2 of the Pharmaceuticals and Medical Devices Law and select a Japanese company approved by the MHLW to act as

a DMAH. This option provides several benefits, including the manufacturing/sales approval being held directly by the non-Japanese company. In addition, the costs for obtaining/maintaining drug approval are lower than in the first two options. Since the approval is under the non-Japanese company's name, there are fewer concerns about the Japanese company acting on its own. If there are problems with the DMAH, the non-Japanese company can designate another company as the DMAH. Compared with the first option, the costs for a DMAH are lower, since there is no need to establish a new company. DMAHs are authorized by the MHLW, licensed for manufacture/sales of pharmaceuticals and provide full support in the drug approval process.
Japan Privacy Laws
Japan has regulatory provisions for privacy protection for personal information, including of patients in clinical trials. Most importantly, the Act on the Protection of Personal Information covers the protection of personal information. Personal information as used in the Act means information about a living individual that can identify the specific individual by name, date of birth or other description contained in such information (including such information as will allow easy reference to other information and will thereby enable the identification of the specific individual).
Pharmaceutical companies in Japan typically adopt their own internal privacy policies based on this law. The requirements tend to be general and leave a good deal of discretion to individual companies, but typically pharmaceutical companies establish policies covering appropriate safeguarding of personal information, prior consent for disclosure, and protection of personal data from leaks or other unauthorized access or disclosure.
The Clinical Research Act establishing clinical research guidelines, similarly, requires persons conducting clinical studies to obtain informed consent of participants and protect participants’ personal data.
Other Countries
In addition to regulations in the United States, the EU, Japan, and potentially the United Kingdom, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials and any commercial sales and distribution of our potential products. Whether or not we obtain FDA approval of a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries. The approval process varies from country to country and the time may be longer or shorter than that required to obtain FDA approval. In addition, the requirements governing the conduct of clinical trials, commercial sales, product licensing, pricing and reimbursement vary greatly from country to country.
Other Regulations
We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. In addition, our international operations and relationships with partners, collaborators, contract research organizations, vendors and other agents are subject to anti-corruption and anti-bribery laws and regulations, including the U.S. Foreign Corrupt Practices Act (“FCPA”), which prohibits U.S. companies and their representatives from engaging in bribery or other prohibited payments to foreign officials for the purpose of obtaining or retaining business. Failure to comply with the FCPA, or similar applicable laws and regulations in other countries, could expose us and our personnel to civil and criminal sanctions. We may incur significant costs to comply with such laws and regulations now or in the future.
Employees
We had 70353 full-time employees as of December 31, 2015.2018. None of our employees are represented by any collective bargaining unit. We believe that we maintain good relations with our employees.

ITEM 1A.
ITEM 1A. RISK FACTORS
We operate in an industry that involves numerous risks and uncertainties. The risks and uncertainties described below are not the only ones we face. Other risks and uncertainties, including those that we do not currently consider material, may impair our business. If any of the risks discussed below actually occur, our business, financial condition, operating results or cash flows could be materially adversely affected. This could cause the trading price of our common stock to decline.
Risks Related to Development, Regulatory Approval and Commercialization
We depend substantially on the success of our FDA-approved product, candidates, particularly Rhopressa and Roclatan®, which are still in development.and our advanced-stage product candidate, RocklatanTM. If we are unable to successfully commercialize our product candidates,Rhopressa® or RocklatanTM, if approved, or experience significant delays in doing so, our business will be materially harmed.
Our business and the ability to generate revenue related to product sales if ever, will depend on the successful commercialization of our FDA-approved product Rhopressa®, which began in April 2018, and the successful development, regulatory approval and commercialization of our current and any future product candidates for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye, particularlyeye. Rhopressa® has been approved by the FDA in the United States, but it has not received regulatory approval in any other jurisdiction and Roclatan, which are stillno sales can be made in development, and other potential products we may develop or license.any jurisdictions outside the United States unless such approval occurs. We have invested a significant portion of our efforts and financial resources in the development of Rhopressa® and RocklatanTM, and our existing product candidates.prospects are highly dependent on, and a significant portion of the value of our company relates to, our ability to successfully commercialize Rhopressa® and RocklatanTM, if approved, in the United States. The success of ourRhopressa®, RocklatanTM and any future product candidates will dependin the United States depends on several factors, including:
successful completion ofsuccessfully completing clinical trials;
receipt ofreceiving and maintaining regulatory approvals from applicable regulatory authorities;
establishment ofdeveloping and maintaining effective sales, marketing and distribution capabilities;
establishing adequate internal manufacturing capacity or arrangements with third-party manufacturers;
obtaining and maintaining patent and trade secret protection and regulatory exclusivity;
protecting our rights in our intellectual property;
launchingestablishing commercial sales of our product candidates, if and when approved;markets;
obtaining reimbursement from third-party payors for product candidates, ifpayers; and when approved;
competitionsuccessfully competing with other products; andproducts.
continued acceptable safety profile for our product candidates following regulatory approval, if and when received.
If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize ourRhopressa®, RocklatanTM or any future product candidates, which could materially harm our business and we may not be able to earn sufficient revenues and cash flows to continue our operations.
The commercial success of Rhopressa® and RocklatanTM and any future product candidates, if approved, will depend on the degree of market acceptance among eye-care professionals, patients, patient advocacy groups, healthcare payers and the medical community.
Commercial activities for Rhopressa® began in April 2018 and our sales force is working to gain market acceptance among eye-care professionals, patients, patient advocacy groups, healthcare payers, including pharmacy benefit managers, and the medical community. The commercial success of Rhopressa® in the United States will depend on the degree of such market acceptance. Similarly, Rhopressa®, if approved in jurisdictions outside the United States, and RocklatanTM and any future product candidates in any jurisdiction in which they may receive approval, may not gain market acceptance among eye-care professionals, patients, patient advocacy groups, healthcare payers, including pharmacy benefit managers, and the medical community. There are a number of available therapies marketed for the treatment of open-angle glaucoma, retinal diseases and other diseases of the eye. Some of these drugs are branded and subject to patent protection, but most others, including latanoprost and many beta blockers, in the case of glaucoma treatment, are available on a generic basis. Many of these approved drugs are well-established therapies and are widely accepted by eye-care professionals, patients and third-party payers. Insurers and other third-party payers may also encourage the use of generic products, either in preference to or prior to the use of brand therapies. The degree of market acceptance of Rhopressa® and RocklatanTM and any future product candidates, if approved, will depend on a number of factors, including:
the market price, affordability and patient out-of-pocket costs, relative to other available products, which are predominantly generics;

the possibility that third-party payers will not give favorable positions on their formularies or will place restrictions on their use, including through use of step therapy or prior authorization programs;
the timing of market introduction;
their effectiveness as compared with currently available products;
eye-care professional willingness to prescribe and patient willingness to adopt them in place of current therapies;
varying patient characteristics including demographic factors such as age, health, race and economic status;
changes in the standard of care for the targeted indications;
the prevalence and severity of any adverse side effects;
limitations or warnings contained in labeling;
limitations in the approved clinical indications and MOA(s);
our success in demonstrating their benefits including relative convenience and ease of initiation, prescription and administration;
the strength of our selling, marketing and distribution capabilities;
the quality of our relationships with eye-care professionals, patient advocacy groups, third-party payers and the medical community;
the continuous availability of quality manufactured products;
sufficient third-party coverage or reimbursement; and
the degree to which the products are subject to material product liability claims.
As we have done with Rhopressa®, it is possible that we may find it necessary or desirable to provide rebates on RocklatanTM or any future product candidates, if approved, to customers or third-party payers or to implement patient assistance programs, including co-pay assistance programs, which could affect our profitability. In addition, we do not know how eye-care professionals, patients and third-party payers will continue to respond to the pricing of Rhopressa® in the United States or how they will respond to the pricing of Rhopressa® in jurisdictions outside the United States, or the pricing of RocklatanTM or any future product candidates in any jurisdiction, if approved.
The market opportunity for our currently marketed or potential products, if approved, are difficult to precisely estimate. Our estimates of these market opportunities for Rhopressa® in the United States and the potential market opportunity for Rhopressa® in jurisdictions outside the United States, RocklatanTM or any future product candidates, if approved, include several key assumptions based on our industry knowledge, industry publications, third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, independent sources have not verified all of our assumptions. If any of these assumptions prove to be inaccurate and the actual market for any of our products post-regulatory approval is smaller than we expect or if we fail to maintain market acceptance or fail to achieve market acceptance, our potential product revenue may be limited, and it may be more difficult for us to achieve or maintain profitability.
If we fail to obtain and sustain an adequate level of coverage and reimbursement for Rhopressa® or RocklatanTM or any future product candidates, if approved, by third-party payers, potential future sales would be materially adversely affected.
The course of treatment for patients with open-angle glaucoma, retinal diseases and other diseases of the eye includes primarily older drugs, and the leading products for the treatment of open-angle glaucoma, retinal diseases and other diseases of the eye currently in the market, including latanoprost and timolol, in the case of glaucoma treatment, are available as generic drugs. Therefore, there will be no commercially viable market for Rhopressa® orRocklatanTM or any future product candidates, if approved, without adequate coverage and reimbursement from third-party payers, and any reimbursement policy may be affected by future healthcare reform measures. We have currently obtained formulary coverage for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans for Rhopressa® in the United States. However, we cannot be certain that those levels of coverage will continue to increase, or that we will be able to maintain those levels of coverage. Further, we cannot be certain that adequate coverage and reimbursement will be available for Rhopressa® in jurisdictions outside the United States or for RocklatanTM or any future product candidates, if approved. Additionally, even if there is a commercially viable market, if the level of coverage or reimbursement is below our expectations, our anticipated revenue and gross margins will be adversely affected.

Third-party payers, such as government or private healthcare insurers and pharmacy benefit managers, carefully review and increasingly question and challenge the coverage of and the prices charged for drugs. Reimbursement rates from private health insurance companies vary depending on the company, the insurance plan and other factors. Reimbursement rates may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. A current trend in the United States healthcare industry is toward cost containment. Large public and private payers, managed care organizations, group purchasing organizations and similar organizations are exerting increasing influence on decisions regarding the use of, and reimbursement levels for, particular treatments. Such third-party payers, including Medicare, may question the coverage of, and challenge the prices charged for, medical products and services, and many third-party payers limit coverage of or reimbursement for newly approved healthcare products. In particular, third-party payers may limit the covered indications. Cost-control initiatives in the U.S. healthcare industry could decrease the price we have established for Rhopressa® or the price we might establish for RocklatanTM or any future product candidates, if approved, which could result in product revenues being lower than anticipated. Rhopressa® is currently priced higher than existing generic drugs and consistently with current branded drugs. If we are unable to show a significant benefit relative to existing generic drugs, Medicare, Medicaid and private payers may not be willing to reimburse for Rhopressa® or RocklatanTM or any future product candidates, if approved, which would significantly reduce the likelihood of them gaining market acceptance. Reimbursement systems in international markets vary significantly by country and by region, and reimbursement approvals must be obtained on a country-by-country basis. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted.
We believe that U.S. third-party payers consider the efficacy, cost effectiveness, safety and tolerability of Rhopressa® and will consider such factors of RocklatanTM and any future product candidates, if approved, and whether use of any such products should be a covered benefit under its health plan in determining whether to approve coverage and reimbursement for such products and at what level. Obtaining these approvals can be a time consuming and expensive process. Our business would be materially adversely affected if we do not maintain approval for reimbursement of Rhopressa® or we do not receive approval for reimbursement of RocklatanTM or any future product candidates, if approved, from third-party payers on a timely or satisfactory basis or if pricing is set at unsatisfactory levels. Limitations on coverage could also be imposed at the local Medicare carrier level or by fiscal intermediaries. Medicare Part D, which provides a pharmacy benefit to Medicare patients as discussed below, does not require participating prescription drug plans to cover all drugs within a class of products. Our business could be materially adversely affected if Part D prescription drug plans were to limit access to, or deny or limit reimbursement of any of our approved products.
Reimbursement in the EU must be negotiated on a country-by-country basis and in many countries the product cannot be commercially launched until reimbursement is approved. The negotiation process in some countries can exceed 12 months. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of any of our products, if approved by the appropriate regulatory authorities, to other available therapies. If the prices for any of our products, if approved by the appropriate regulatory authorities, decrease or if governmental and other third-party payers do not provide adequate coverage and reimbursement levels, our revenue, potential for future cash flows and prospects for profitability will suffer. Also, we may not be able to launch the product uniformly throughout the EU but may have to commence commercial operations on a country-by-country basis, which could complicate the launching process and negatively affect our sales.
We face competition from established branded and generic pharmaceutical companies and if our competitors are able to develop and market products that are preferred over our products, our commercial opportunity will be reduced or eliminated.
The development and commercialization of new drug products is highly competitive. We face competition from established branded and generic pharmaceutical companies and smaller biotechnology and pharmaceutical companies, as well as from academic institutions, government agencies and private and public research institutions, which may in the future develop products to treat patients with open-angle glaucoma, retinal diseases and other diseases of the eye. We currently compete directly against companies producing existing and future glaucoma treatment products. To the extent we develop proprietary compounds for use beyond glaucoma, we will face competition from companies, academic institutions, government agencies and private and public research institutions operating in such new therapeutic areas.
Many of our competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Early-stage companies are also developing treatments for open-angle glaucoma, retinal diseases and other diseases of the eye and may prove to be significant competitors. In September 2018, Sun Pharmaceuticals Industries Ltd. received FDA approval for a PGA indicated for the reduction of IOP in patients with open-angle glaucoma or ocular hypertension. We expect that our competitors will continue to develop new treatments for open-angle glaucoma, retinal diseases and other diseases of the eye, which may include eye drops, oral treatments, surgical procedures, implantable devices or laser treatments. Alternative

treatments beyond eye drops continue to develop. For example, although surgical procedures are currently used in severe cases, less invasive procedures are currently under development and we expect that we will compete with other companies that develop implantable devices or other products or procedures for use in the treatment of open-angle glaucoma, retinal diseases and other diseases of the eye.
Other early-stage companies may also compete through collaborative arrangements with large and established companies. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Our commercial opportunity will be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer adverse effects, are more convenient or are less expensive than any products that we may develop. In addition, competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours.
In addition, our ability to compete may be affected because in many cases insurers or other third-party payers encourage the use of generic products. Ophthalmology is currently dominated by generic drugs, such as latanoprost and timolol, in the case of glaucoma treatment, and additional products are expected to become available on a generic basis over the coming years. Rhopressa® is priced at a premium over competitive generic products and consistent with other branded glaucoma drugs and we expect that RocklatanTM, if approved, will be priced similarly. Our ability to compete effectively will depend upon, among other things, our ability to:
successfully complete clinical trials and obtain all requisite regulatory approvals in a timely and cost-effective manner;
obtain and maintain patent protection and non-patent exclusivity in all current and potential commercial jurisdictions for our products;
attract and retain key personnel;
develop effective manufacturing capabilities and continue to build an effective selling and marketing infrastructure;
demonstrate the advantages of our products compared to alternative therapies, including, in the case of Rhopressa® and RocklatanTM, if approved, other currently marketed PGA and non-PGA products;
identify and develop additional product candidates to expand our current product portfolio;
compete against other products with fewer contraindications; and
obtain and sustain adequate reimbursement from third-party payers.
If our competitors market products that are more effective, safer, have fewer side effects or are less expensive than our products or that reach the market sooner than any of our future product candidates, if approved, we may not achieve commercial success.
If we are unable to establish a direct sales force in jurisdictions outside the United States, our business may be harmed.
We have no experience selling, marketing or distributing any drug product in any jurisdictions outside the United States, and we currently are just beginning to establish a commercially-oriented presence in jurisdictions outside the United States. Other companies have experienced unsuccessful product launches and failed to meet expectations of market potential, including companies with significantly more experience and resources than us, and there can be no guarantee that we will successfully launch any product in any jurisdictions outside the United States. To achieve commercial success for Rhopressa® in jurisdictions outside the United States, we must either develop a sales and marketing organization in such jurisdictions or outsource these functions to third parties. We currently plan to commercialize Rhokiinsa® and RoclandaTM, if approved, in Europe on our own and likely partner for commercialization in Japan. We will incur significant additional expenses and commit significant additional time and management resources to establish and train a sales force to market and sell our products in jurisdictions outside the United States. We may not be able to successfully establish these capabilities on our expected timing or at all despite these additional expenditures.
Factors that may inhibit our efforts to successfully establish a sales force in jurisdictions outside the United States include:
an inability to compete with other pharmaceutical companies to recruit, hire, train and retain adequate numbers of effective sales and marketing personnel with requisite knowledge of our target market;
an inability to effectively manage a geographically dispersed sales and marketing organization in such jurisdictions;

the inability of sales personnel to obtain access to adequate numbers of eye-care professionals to prescribe any future approved products;
failure to adhere to regulatory requirements governing the sale of products in any jurisdiction;
unforeseen costs and expenses associated with creating an independent sales and marketing organization; and
a delay in bringing products to market after efforts to hire and train our sales force have already commenced.
In the event we are unable to successfully market and promote our products, our business may be harmed.
We have not obtained regulatory approval for any of our product candidates inRhopressa® outside the United States or for RocklatanTM in any other country.jurisdiction.
Rhopressa®, which has been approved by the FDA for the reduction of elevated IOP in patients with open-angle glaucoma or ocular hypertension, is our only product that has received regulatory approval. We currently do not yet have any product candidatesproducts that have gainedreceived regulatory approval for sale in any jurisdictions outside the United States or any other country, and weStates. We cannot guarantee that we will ever have any other marketable products. Our business is substantially dependent on our ability to complete the development of, obtain regulatory approval for and successfully commercialize product candidates in a timely manner. We cannot commercialize product candidates in the United States without first obtaining regulatory approval to market each product from the FDA; similarly, we cannot commercialize product candidates outside of the United States without obtaining regulatory approval from comparable foreign regulatory authorities.
Phase 3 trials forWith respect to approval of Rhopressa® commenced in July 2014 andoutside the United States, we completed our initiala Phase 3 registration trial, named “Rocket 1,4, which was designed to measure efficacy over three months.generate adequate six-month safety data for European regulatory approval. In the fourth quarter of 2018, the EMA accepted our MAA for Rhopressa®, which will be marketed under the name Rhokiinsa® in Europe, if approved. The Rocket 1acceptance of our filing in no way means that the EMA agrees with our interpretation of the outcome of the clinical trial did not meet its primary efficacy endpoint of demonstrating non-inferiority of intraocular pressure,data or IOP, lowering for once-daily Rhopressa compared to twice-daily timolol, but did achieve its pre-specified secondary endpoint. We evaluated the data and results from Rocket 1 and obtained agreement from the FDA to change the IOP range usedwill issue an approval for the primary endpoint of our secondproduct in the EU. Additionally, we completed a Phase 3 registration1 clinical trial named “Rocketand a successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which iswere designed to measure efficacy over three monthssupport meeting the requirements of Japan’s Pharmaceuticals and assess safety over 12 months.

In addition, the recently reported topline 12-month safety data from Rocket 2 confirmed a positive safety profile for the drug and demonstrated a consistent IOP lowering effect throughout the 12-month period at the specified timepoint.in Japan. We are also currently conductingplanning to initiate a one year, safety-only study in Canada, named “Rocket 3,” and an additional Phase 3 registration trial for

Rhopressa, named “Rocket 4,” which commenced in September 2015. Rocket 4 was initiated by Aerie in part to gain adequate safety data for regulatory filings in Europe. Based upon recent discussions with the FDA, we expect to submit a new drug application (“NDA”) for Rhopressa in the third quarter of 2016 utilizing Rocket 2 as the pivotal clinical trial and Rocket 1 as supportiveon Japanese patients in nature. We do not anticipate that completionJapan by the end of Rocket 4 will be necessary prior to submitting the NDA.
The first Phase 3 registration trial for Roclatan, named “Mercury 1,” commenced in September 2015. We expect to commence our second Phase 3 registration trial for Roclatan, named “Mercury 2,” in the first quarter of 2016. If both of these2019 to support subsequent Phase 3 registration trials that are successful, we expectexpected to filebe conducted in Japan.
We cannot predict how long it will take to obtain approval in Japan and if our clinical trials ultimately are successful. We will need to ensure that our planned Phase 2 clinical trial on Japanese patients in Japan and subsequent Phase 3 registration trials in Japan comply with all applicable regulations. Any failure to fully comply with Japanese regulations could result in the regulatory authorities requesting corrections or requiring new clinical trials be conducted, which could cause delay in obtaining the approval.
We submitted an NDA for RoclatanRocklatanTM to the FDA in May 2018 under Section 505(b)(2) of the FDCA, because RocklatanTM is a fixed dose combination of two FDA-approved drugs in the United States, Section 505(b)(2) permits us to rely on the FDA’s prior findings of safety and effectiveness for Rhopressa® and latanoprost. In July 2018, the FDA accepted the NDA for review and the PDUFA goal date was set for March 14, 2019, which represents a ten-month review. This was communicated by the FDA via a “Day 74” letter, which also stated that the application is sufficiently complete to permit a substantive review and that the FDA had not identified any application deficiencies. The “Day 74” letter did not mention the need for an advisory committee. The issuance of the “Day 74” letter without mention of deficiencies or an advisory committee does not mean that FDA will not identify deficiencies during its substantive review that may preclude approval or that the FDA will not later determine that an advisory committee is appropriate. It is possible that the “shutdown” of the U.S. federal government that began in December 2018 and ended in January 2019 will affect FDA’s ability to meet its goal of reviewing our application by March 14, 2019, which could cause delay in our obtaining approval, if ever.
We have completed two Phase 3 registration trials for RocklatanTM, named Mercury 1 and Mercury 2. Both Mercury 1 and Mercury 2 achieved their 90-day primary efficacy endpoints of demonstrating statistical superiority of RocklatanTM over each of its components at all measured time points in patients with maximum baseline IOPs of above 20 mmHg to below 36 mmHg.
With respect to RocklatanTM in jurisdictions outside the second halfUnited States, Mercury 1 and Mercury 2 will also be used to apply for EMA approval of 2017, approximately one year behind RhopressaRoclandaTM. We also plan to initiateIn addition, we initiated a third Phase 3 registration trial for RoclandaTM, named Mercury 3. If successful, Mercury 3 is expected to improve our commercialization prospects in Europe. We currently expect to read out topline 90-day efficacy data for the trial in 2019 and expect to submit an MAA with the EMA for RoclandaTMin Europe named “Mercury 3,” in the first half of 2017. Mercury 3 will be designed to compare Roclatanearly 2020, if Rhokiinsa® to a broadly marketed fixed dose combination product in Europe.is approved by the EMA. See “Business—Overview” for more information about Mercury 1, Mercury 2 and Mercury 3.
We cannot predict whether theseongoing trials and future trials will be successful or whether regulators will agree with our

conclusions regarding the preclinical studies and clinical trials we have conducted to date.

FDA approval of Rhopressa
® does not constitute FDA approval of RocklatanTM, and there can be no assurance that we will receive FDA approval for RocklatanTM or any future product candidates. FDA approval of Rhopressa® and the EMA acceptance of our MAA for Rhokiinsa® do not constitute regulatory approval of Rhopressa® or Rhokiinsa® in jurisdictions outside the United States, and there can be no assurance that we will receive regulatory approval for Rhopressa® or Rhokiinsa® in jurisdictions outside the United States.
Before obtaining regulatory approvals for the commercial sale of any product candidate for a target indication, we must demonstrate in preclinical studies and well-controlled clinical trials, and, with respect to approval in the United States, to the satisfaction of the FDA, that the product candidate is safe and effective for use for that target indication and that the manufacturing facilities, processes and controls are adequate. In the United States, we have not submitted an NDA for any of our product candidates. An NDA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the product.
Obtaining approval of an NDA is a lengthy, expensive and uncertain process, and approval may not be obtained. If we submit an NDA to the FDA, the FDA must decide whether to file the NDA or refuse to file the NDA. WeAn NDA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the product. Although we believe our NDA for RocklatanTM contained substantial evidence of effectiveness for the product, we cannot be certainguarantee that any submissionsthe NDA will be filedapproved by the FDA. In addition, we may be required to supplement the RocklatanTM NDA with additional information and/or receive unfavorable feedback from the FDA regarding the likelihood of obtaining FDA approval for RocklatanTM. Further, restructuring efforts are underway at the FDA pursuant to which the organizational positioning within the FDA of the Ophthalmic Group is being reevaluated, which may affect the FDA’s focus on new ophthalmic therapies.
Regulatory authorities outside of the United States, such as in Europe and Japan and in emerging markets, also have requirements for approval of drugs for commercial sale with which we must comply prior to marketing in those areas. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our product candidates. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and obtaining regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approval could require additional non-clinical studies or clinical trials, which could be costly and time consuming. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval. For all of these reasons, we may not obtain foreign regulatory approvals on a timely basis, if at all.
The process to develop, obtain regulatory approval for and commercialize product candidates is long, complex and costly both inside and outside of the United States, and approval is never guaranteed. Even if ourRhopressa®, RocklatanTM, Rhokiinsa®, RoclandaTM and any future product candidates were to successfully obtain approval from the regulatory authorities, any approval might significantly limit the approved indications for use, or require that precautions, contraindications, or warnings be included on the product labeling, or require expensive and time-consuming post-approval clinical studies or surveillance as conditions of approval. Following any approval for commercial sale of our product candidates,any products we may develop, certain changes to the product, such as changes in manufacturing processes and additional labeling claims, will be subject to additional FDA review and approval.approval by the FDA and other regulatory authorities. Also, regulatory approval for Rhopressa®, RocklatanTM, Rhokiinsa®, RoclandaTM or any of ourfuture product candidates, if approved, may be withdrawn. If we are unable to obtain regulatory approval for ourRhopressa® or RocklatanTM (named Rhokiinsa® and RoclandaTM in Europe, respectively) outside the United States or for RocklatanTM or any future product candidates in one or more jurisdictions, or any approval contains significant limitations, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed. Furthermore, we may not be able to obtain sufficient funding or generate sufficient revenue and cash flows to continue the development of any other product candidate in the future.
Regulatory approval may be substantially delayed or may not be obtained for oneRhopressa® in jurisdictions outside the United States or all of ourfor RocklatanTM or any future product candidates in any jurisdiction if regulatory authorities require additional time or studies to assess the safety and efficacy of our product candidates.efficacy.
We may be unable to initiate or complete development of our product candidatesRhopressa® or RocklatanTM (named Rhokiinsa® and RoclandaTM in Europe, respectively) in jurisdictionsoutside the United States on schedule, if at all. If applicable regulatory authorities require additional time or studies to assess the safety or efficacy of any of our product candidates, we may require funding beyond the amounts currently on our balance sheet. In addition, in the event of any unforeseen costs or other business decisions, we may not have or be able to obtain adequate funding to complete the necessary steps for approval for any or all of our product candidates. Preclinical studies and clinical trials required to demonstrate the quality, safety and efficacy of our product candidatesdrug products are time consuming and expensive and together take several years or more to complete. Delays in regulatory approvals or rejections of

applications for regulatory approval in the United States, Europe, Japan or other markets may result from many factors, including:
our inability to obtain sufficient funds required for a clinical trial;

27



regulatory requests for additional analyses, reports, data, non-clinical and preclinical studies and clinical trials;
regulatory questions regarding interpretations of data and results and the emergence of new information regarding our product candidates or other products;
clinical holds, other regulatory objections to commencing or continuing a clinical trial or the inability to obtain regulatory approval to commence a clinical trial in countries that require such approvals;
failure to reach agreement with the FDA or non-U.S.applicable regulators regarding the scope or design of our clinical trials;
our inability to enroll a sufficient number of patients who meet the inclusion and exclusion criteria in our clinical trials;
our inability to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
unfavorable or inconclusive results of clinical trials and supportive non-clinical studies, including unfavorable results regarding the effectiveness or safety of product candidates during clinical trials;
any determination that a clinical trial or product candidate presents unacceptable health risks;
lack of adequate funding to continue the clinical trial due to unforeseen costs or other business decisions;
our inability to reach agreements on acceptable terms with prospective contract research organizations or CROs,(“CROs”) and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
our inability to identify and maintain a sufficient number of sites, many of which may already be engaged in other clinical trial programs, including some that may be for the same indications targeted by any of our product candidates;
our inability to obtain approval from institutional review boardsIRBs to conduct clinical trials at their respective sites;
the failure of a third party to comply with applicable regulatory requirements, including site inspections and inspection readiness;
our inability to timely manufacture or obtain from third parties sufficient quantities or quality of the product candidate or other materials required for a clinical trial; and
difficulty in maintaining contact with patients after treatment, resulting in incomplete data.
Changes in regulatory requirements and guidance may also occur and we may need to amend clinical trial protocols submitted to applicable regulatory authorities to reflect these changes. Amendments may require us to resubmit clinical trial protocols to institutional review boardsIRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial.
If we are required to conduct additional clinical trials or other studies with respect to any of our product candidates beyond those that weare initially contemplated, if we are unable to successfully complete our clinical trials or other studies or if the results of these studies are not positive or are only modestly positive, we may be delayed in obtaining regulatory approval for that product candidate, we may not be able to obtain regulatory approval at all or we may obtain approval for indications that are not as broad as intended. Our product development costs will also increase if we experience delays in testing or approvals and we may not have sufficient funding to complete the testing and approval process. Significant clinical trial delays could allow our competitors to bring products to market before we do and impair our ability to commercialize our products if and when approved. If any of this occurs, our business will be materially harmed.
In addition, unless otherwise agreed with the other member states of the EU, the United Kingdom will leave the EU in March 2019 (“Brexit”). As one of the Brexit consequences, the EMA is in the process of relocating from London to Amsterdam, and it is possible that approvals for new medicinal products, and other regulatory actions involving the EMA, may be considerably delayed. It is uncertain what other impacts Brexit will have with respect to the cross-border acknowledgment of clinical trial results and marketing authorizations. It is possible that a separate marketing application and approval will be required to market a product in the United Kingdom. There are political endeavors to minimize the effects of Brexit in this area but there is no certainty that these efforts will be successful. If Brexit results in market access delays in Europe or the requirement for additional marketing approvals, our business may be materially harmed.

The failure by U.S. Congress to timely approve a budget for the federal government and its agencies, including the FDA, could have a material adverse effect on our business.
On an annual basis, U.S. Congress must approve budgets that govern spending by the federal agencies, including the FDA. If Congress cannot agree on a budget, or if the President vetoes a budget approved by Congress, then the federal government may be shut down and non-essential federal employees, including many FDA employees, may be furloughed. Such a shutdown would prevent the FDA from performing many of its duties, which are crucial to our business. On December 22, 2018, due to a lapse in appropriations for the federal government, most of the federal government was shut down, including many functions of the FDA, and most of the federal employees were furloughed. The federal government received appropriations to temporarily reopen as of January 25, 2019 and received the remainder of the appropriations for the fiscal year as of February 15, 2019. Although the federal government has now reopened, the recent and any future government shutdown could affect, among other things, the FDA approval process of RocklatanTM, which could have a material adverse effect on our business. For example, the FDA may need additional time to review the NDA for RocklatanTM due to the time that the government was shut down and therefore approval by the FDA, if obtained, may occur after the PDUFA date of March 14, 2019. Additionally, the FDA may have a backlog due to the government shutdown and as such, supplier qualifications, IND review and acceptance and other functions that the FDA performs may be delayed. Such a backlog could delay our NDA review process for RocklatanTM and subsequent commercialization, if approved, among other things, which could have a material adverse effect on our business.
Failure can occur at any stage of clinical development. If the clinical trials for our current and potential future product candidates are unsuccessful, we could be required to abandon development.
A failure of one or more clinical trials can occur at any stage of testing for a variety of reasons. The outcome of preclinical testing and early clinical trials may not be predictive of the outcome of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. In addition, adverse events may occur or other risks may be discovered in Phase 3 clinicalregistration trials that may cause us to suspend or terminate our clinical trials. In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in or adherence to trial protocols, differences in size and type of the patient populations and the rates of dropout among clinical trial participants. Our future clinical trial results therefore may not demonstrate safety and efficacy sufficient to obtain regulatory approval for our current and potentialRhopressa® in jurisdictions outside the United States or for RocklatanTM or any future product candidates.candidates in any jurisdiction.

Flaws in the design of a clinical trial may not become apparent until the clinical trial is well-advanced or after data results have been obtained. We have limited experience in designing clinical trials and may be unable to design and execute a clinical trialtrials to support regulatory approval. In addition, clinical trials often reveal that it is not practical or feasible to continue development efforts. Further, we have never submitted an NDA for any potential products.
We may voluntarily suspend or terminate our clinical trials if at any time we believe that they present an unacceptable risk to participants. Further, regulatory agencies, institutional review boardsIRBs or data safety monitoring boards may at any time order the temporary or permanent discontinuation of our clinical trials or request that we cease using investigators in the clinical trials if they believe that the clinical trials are not being conducted in accordance with applicable regulatory requirements, or that they present an unacceptable safety risk to participants. Since our inception, we have not voluntarily or involuntarily suspended or terminated a clinical trial due to unacceptable safety risks to participants.
If the results of any of our clinical trials for our current product candidates or clinical trials for any future product candidates do not achieve the primary efficacy endpoints or demonstrate unexpected safety issues, the prospects for approval of our product candidates will be materially adversely affected. Moreover, preclinical and clinical data are often susceptible to varying interpretations, analyses and entry criteria, and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials have failed to achieve similar results in later clinical trials, including longer term trials, or have failed to obtain regulatory approval of their product candidates. Many compounds that initially showed promise in clinical trials or earlier stage testing have later been found to cause undesirable or unexpected adverse effects that have prevented further development of the compound. Our ongoing clinical trials for our primary product candidates,regulatory approval for Rhopressa® and RoclatanRocklatanTM, in jurisdictions outside the United States may not produce the results that we expect and remain subject to the risks associated with clinical drug development as indicated above.
SeveralOther companies have previously pursued ROCK inhibitors for ophthalmic use but to date no ROCK inhibitors, other than Rhopressa®, have been approved and most of those companies have chosen to discontinue clinical development of their ROCK inhibitors. One of our ROCK inhibitors, AR-12286, was discontinued in the clinical stage of development due to an inability to maintain its effectiveness over time. In a 28-day Phase 2b clinical trial, AR-12286 lowered IOP by 6.7 mmHg on day seven, but lowered IOP by only 5.3 mmHg on day 28. This trend continued in a follow-up three-month study. As a result, in June 2013 we discontinued any further clinical development of AR-12286 and its fixed-dose combination product PG286.
United States. In April 2015, we announced that Rocket 1 did not meet its primary efficacy endpoint of demonstrating non-inferiority of IOP loweringreduction for once-daily RhopressaTM® compared to twice-daily timolol but did achieve its pre-specified secondary endpoint. We evaluated the data and results from Rocket 1 and obtained agreement from the FDA to change the IOP range used for the primary endpoint of Rocket 2 which is designed to measure efficacy over three months and assess safety over 12 months. The modified clinical endpoint range for Rocket 2 was set to a level where Rocket 1 would have been successful.

In September 2015, the Rocket 2 trial achieved its primary efficacy endpoint of demonstrating non-inferiority of Rhopressa® compared to timolol. In addition to successfully achieving non-inferiority to timolol at this endpoint range, the recently reported topline 12-month safety data from Rocket 2 confirmed a positive safety profile for the drug and demonstrated a consistent IOP loweringreducing effect throughout the 12-month period at the specified timepoint.
If based on the clinical results of Rhopressa, we discontinue the advancement of this product candidate, in certain circumstances we may similarly determine not to advance Roclatan, which combines Rhopressa with latanoprost. Additionally, ourOur clinical trials arewere designed to test the use of Rhopressa® and RoclatanRocklatanTM as a monotherapy, rather than as an add-onadjunctive therapy. Accordingly, the efficacy of our primary product candidatesRhopressa® and RocklatanTM as a monotherapy may not be similar or correspond directly to their efficacy when used as an add-onadjunctive therapy, which we expect will be a primary use of Rhopressa®.
In February 2014, we reportedThe breadth of the resultslabeling of a preclinical animal study sponsored by Aerie, whereby the administrationany product or product candidate, if approved, will depend upon providing evidence of RhopressaTM eye drops demonstrated statistically significant reductions in EVP and IOP in rabbits following the third daily dose. Based on the results of this preclinical study, together with the consistent IOP-lowering effect of RhopressaTM demonstrated in our prior clinical trials, we believe the reduction of EVPsuch product’s MOA(s) that is an additional MOA of RhopressaTM and RoclatanTM. However, like the other differentiated MOAs of our product candidates, increasing outflow through the TM and decreasing fluid production in the eye, our product candidates’ effect on EVP has not been studied in humans and neither our ongoing, nor our planned, Phase 3 registration trials for RhopressaTM or RoclatanTM will be designed to demonstrate reduction of EVP or other MOAs of our product candidates. If we are not able to demonstratesatisfactory to the satisfaction of the FDA and relevant non-U.S. regulators the reduction of EVP, or any of the other differentiated MOAs of our product candidates, even if we otherwise obtainapplicable regulatory approval for RhopressaTM and RoclatanTM, it couldauthority. Failure to do so will limit the types of claims we will be able to make in our marketing and labeling of our product candidates.Rhopressa

We believe Rhopressa®, Rhokiinsa®, RocklatanTM, if approved, will compete against non-PGA products as a preferred adjunctive therapy to PGAs. In addition, if approved, we believe that Rhopressa may also become a preferred therapy in several populations including where patients have low to moderately elevated IOPs at the time of diagnosis. No patients with low-tension glaucoma have been or will be included in these clinical trials, and our expectations with respect to subjects with low IOP are based to a large extent on extrapolation of results for subjects with moderately elevated IOP. Even if ourany future product candidates, were to obtain regulatoryif approved. For example, based on the results of our preclinical and clinical studies, we believed Rhopressa® and RocklatanTM reduced IOP through additional MOAs; however, Rhopressa® received FDA approval if we are unable to support claims about ourfor one MOA, ROCK inhibition or the mechanism by which Rhopressa® increases outflow of aqueous humor through the TM, as reflected in the Rhopressa® product candidates to the satisfaction of the FDA and relevant non-U.S. regulators, including claims with respect to the efficacy of Rhopressa as an adjunctive therapy or for patients with low IOP, it could limit the types of claims we will be able to make in our marketing and product labeling of these product candidates.labeling.
In addition to the circumstances noted above, weWe may experience numerous unforeseen events that could cause our clinical trials to be unsuccessful, delayed, suspended or terminated, or which could delay or prevent our ability to receive regulatory approval or commercialize our current and potential future product candidates, including:
 
clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or implement a clinical hold;
the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipateestimate or participants may drop out of these clinical trials at a higher rate than we anticipate;
our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
regulators or institutional review boardsIRBs may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;
we may have delays in reaching or fail to reach agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites;
we may elect or be required to suspend or terminate clinical trials of our product candidates based on a finding that the participants are being exposed to health risks;
the cost of clinical trials of our product candidates may be greater than we anticipate;
the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate; and
our product candidates may have undesirable adverse effects or other unexpected characteristics.
If we elect or are required to suspend or terminate a clinical trial, of any of our current and potential future product candidates, our commercial prospects will be adversely impacted and our ability to generate product revenues may be delayed or eliminated.
IfRhopressa®, RocklatanTM or any future product candidates may have undesirable or adverse effects, which may result in the delay, denial or withdrawal of regulatory approval or may require our products to be taken off the market, require them to include safety warnings or otherwise limit their sales after regulatory approval is received.
Unforeseen adverse effects from Rhopressa®, RocklatanTM or any future product candidates could arise either during clinical development or, even after approval, after the approved product has been marketed. To date, the main tolerability finding of Rhopressa® has been mild conjunctival hyperemia, or eye redness. In our Phase 3 registration trials, some patients also experienced conjunctival hemorrhages, or petechiae, corneal verticillata, blurry vision, and decreased visual acuity as adverse events. RocklatanTM combines Rhopressa® with latanoprost. To date, the main tolerability finding of RocklatanTM has also been mild conjunctival hyperemia, which was reported in approximately 63% of patients and was scored as mild for approximately 70% of affected patients in the 12-month safety data from Mercury 1. In our Phase 3 registration trials, some patients also experienced conjunctival hemorrhage, eye pruritus, increased lacrimation, reduced visual acuity, blepharitis, punctate keratitis and corneal disorder as adverse events. The main adverse effects of latanoprost include conjunctival hyperemia, irreversible change in iris color, discoloration of the skin around the eyes and droopiness of eyelids caused by the loss of orbital fat.

While the FDA granted approval of Rhopressa® based on the data included in the NDA, we do not know whether the results when a larger number of patients in broader populations are unableexposed to establish a direct sales force,Rhopressa®, including results related to safety and efficacy, will be consistent with the results from our businessearlier clinical studies of Rhopressa® that served as the basis of FDA approval of Rhopressa®. New data relating to Rhopressa®, including from any adverse event reports or any negative results during clinical development for additional indications of Rhopressa®, may emerge at any time.
Any undesirable or adverse effects that may be harmed.
We currently do not have an established sales organization and do not have a marketingcaused by any such products or distribution infrastructure. To achieve commercial success for any approved product, we must either develop a sales and marketing organization or outsource these functions to third parties. If our product candidates are approvedcould interrupt, delay or halt clinical trials and could result in the delay, denial or withdrawal of regulatory approval by the FDA or other regulatory authorities for commercial sale, we intend to market directly to eye-care professionalsany or all targeted indications, and in North America through our own sales force, targeting approximately 10,000 high-prescribing eye-care professionals. If ourturn prevent us from successfully commercializing Rhopressa® or RocklatanTM or any future product candidates, areif approved, in Europe for commercial sale and generating or continuing to generate revenues from their sale. In addition, if we self-commercialize ouror others identify undesirable or adverse effects caused by Rhopressa® or, if approved, RocklatanTM or any future product candidates in Europe,after regulatory approval we will needcould face one or more of the following consequences:
regulatory authorities may re-review the product and impose restrictions on its distribution;
regulatory authorities may require the addition of labeling statements, such as a boxed warning or a contraindication, or other safety labeling changes;
regulatory authorities may require a Risk Evaluation and Mitigation Strategy (“REMS”);
regulatory authorities may withdraw their approval of the product;
regulatory authorities may seize the product;
we may be required to establish similar functionschange the way that the product is promoted or outsource these functionsadministered, conduct additional clinical trials or recall such product;
we may be subject to third parties. We will need to incur significant additional expenseslitigation or product liability claims fines, injunctions or criminal penalties; and commit significant additional time and management resources to establish and train a sales force to market and sell our products. We may not be able to successfully establish these capabilities despite these additional expenditures.
Factors that may inhibit our efforts to successfully establish a sales force include:
our inability to compete with other pharmaceutical companies to recruit, hire, train and retain adequate numbersreputation may suffer.
Any of effective sales and marketing personnel with requisite knowledgethese events could prevent us from achieving or maintaining market acceptance of our target market;
the inability of sales personnel to obtain access to adequate numbers of eye-care professionals to prescribe any future approved products;
unforeseenaffected product or could substantially increase the costs and expenses associated with creating an independent sales and marketing organization; and

acommercializing such product, which in turn could delay in bringing productsor prevent us from generating or continuing to market after efforts to hire and train our sales force have already commenced.
In the event we are unable to successfully market and promote our products, our business may be harmed.generate revenues from its sale.
We currently have international operations andoperations. We intend to explore the licensing of commercialization rights or other forms of collaboration outside of North America and to develop internal manufacturing capabilities in Ireland, both of which will expose us to additional risks of conducting business in international markets.
Markets outside of North America are an important component of our growth strategy. As part of this strategy, in March 2015 and April 2015, we formed Aerie Limited and Aerie Ireland Limited, respectively. If we fail to successfully commercialize, obtain licenses or enter into collaboration arrangements with selling parties, or if these parties are not successful, our revenue-generating growth potential will be adversely affected. As part of this strategy, in March 2015 and April 2015, we formed Aerie Limited and Aerie Ireland Limited, respectively. Additionally, in January 2017, we commenced establishment of our own manufacturing plant in Athlone, Ireland, which is expected to produce commercial supplies of Rhopressa® and, if approved, RocklatanTM, Rhokiinsa and RoclandaTM in early 2020. We also opened an office in Tokyo in October 2018 to assist with our expected expansion into Japan. If we fail to develop internal manufacturing capabilities we may be forced to continue to rely on third-party manufacturers, which could adversely affect our results of operations and financial condition. Moreover, international operations and business relationships subject us to additional risks that may materially adversely affect our ability to attain or sustain profitable operations, including:
efforts to enter into or expand collaboration or licensing arrangements with third parties in connection with our international sales, marketing, manufacturing and distribution efforts may increase our expenses or divert our management’s attention from the acquisition or development of product candidates;
changes in a specific country’s or region’s political and cultural climate or economic condition;condition or changes in governmental regulations and laws;
differing regulatory requirements for drug approvals, manufacturing and marketing internationally;
difficulty of effective enforcement of contractual provisions in local jurisdictions;
potentially reduced protection for intellectual property rights;
potential third-party patent rights in countries outside of the United States;
unexpected changes in tariffs, trade barriers and other regulatory requirements;requirements including those governing data privacy;

divergent environmental laws and regulations;
economic weakness, including inflation, or political instability, particularly in non-U.S. economies and markets, including several countries in Europe;
compliance with tax, employment, immigration and labor laws for employees traveling abroad;
the effects of applicable foreign tax structures and potentially adverse tax consequences;consequences (including the tax reform law that was enacted in the United States in December 2017 that creates uncertainty with respect to the tax impact on our business operations and profitability);
foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incidental to doing business in another country;
workforce uncertainty in countries where labor unrest is more common than in the United States;
the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import goods from a foreign market (with low or lower prices) rather than buying them locally;
failure of our employees and contracted third parties to comply with Office of Foreign Asset Control rules and regulations and the Foreign Corrupt Practices Act;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters, including earthquakes, volcanoes, typhoons, tsunamis, floods, hurricanes and fires.
These and other risks may materially adversely affect our business, results of operations, financial condition or ability to attain or sustain revenue from international markets.
Our product candidates may have undesirable adverse effects, which may delay or prevent regulatory approval or, if approval is received, require our products to be taken off the market, require them to include safety warnings or otherwise limit their sales.
Unforeseen adverse effects from any of our product candidates could arise either during clinical development or, if approved, after the approved product has been marketed. To date, the main tolerability finding of RhopressaTM has been mild hyperemia, or eye redness. We recently reported 12-month safety data from Rocket 2, in which some patients also experienced conjunctival hemorrhages, corneal deposits, blurry vision, and decreased visual acuity as adverse events. RoclatanTM combines RhopressaTM with latanoprost. To date, the main tolerability finding of RoclatanTM has also been mild hyperemia. The main adverse effects

31



of latanoprost include hyperemia, irreversible change in iris color, discoloration of the skin around the eyes and droopiness of eyelids caused by the loss of orbital fat.
Any undesirable adverse effects that may be caused by our product candidates could interrupt, delay or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications, and in turn prevent us from commercializing our product candidates and generating revenues from their sale. In addition, if any of our product candidates receives regulatory approval and we or others later identify undesirable adverse effects caused by the product, we could face one or more of the following consequences:
regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication, or other labeling changes;
regulatory authorities may withdraw their approval of the product;
regulatory authorities may seize the product;
we may be required to change the way that the product is administered, conduct additional clinical trials or recall the product;
we may be subject to litigation or product liability claims fines, injunctions, or criminal penalties; and
our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase the costs and expenses of commercializing such product, which in turn could delay or prevent us from generating revenues from its sale.
We face competition from established branded and generic pharmaceutical companies and if our competitors are able to develop and market products that are preferred over our products, our commercial opportunity will be reduced or eliminated.
The development and commercialization of new drug products is highly competitive. We face competition from established branded and generic pharmaceutical companies, as well as from academic institutions, government agencies and private and public research institutions, which may in the future develop products to treat patients with glaucoma or other diseases of the eye. Many of our competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. In July 2015, Bausch + Lomb Inc., a wholly owned subsidiary of Valeant Pharmaceuticals International, Inc., filed an NDA for a nitric oxide-donating latanoprost, which is currently under review by the FDA for the treatment of open angle glaucoma and ocular hypertension. Additionally, early-stage companies are also developing treatments for glaucoma and other diseases of the eye and may prove to be significant competitors, including Inotek Pharmaceuticals, which is developing an adenosine receptor agonist. We expect that our competitors will continue to develop new treatments for glaucoma and other diseases of the eye, which may include eye drops, oral treatments, surgical procedures, implantable devices or laser treatments. Alternative treatments beyond eye drops continue to develop. For example, although surgical procedures are currently used in severe cases, less invasive procedures are currently under development and we expect that we will compete with other companies that develop implantable devices or other products or procedures for use in the treatment of glaucoma or other diseases of the eye.
Other early-stage companies may also compete through collaborative arrangements with large and established companies. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Our commercial opportunity will be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer adverse effects, are more convenient or are less expensive than our potential products. We expect that our ability to compete effectively will depend upon, among other things, our ability to:
successfully complete clinical trials and obtain all requisite regulatory approvals in a timely and cost- effective manner;
obtain and maintain patent protection and non-patent exclusivity for our products and otherwise prevent the introduction of generics of our products;
attract and retain key personnel;
build an effective selling and marketing infrastructure;

32



demonstrate the advantages of our product candidates compared to alternative therapies, including currently marketed PGA and non-PGA products;
compete against other products with fewer contraindications; and
obtain and sustain adequate reimbursement from third-party payors.
If our competitors market products that are more effective, safer, have fewer side effects or are less expensive than our potential products or that reach the market sooner than our future products, if any, we may not achieve commercial success.
The commercial success of our potential products will depend on the degree of market acceptance among eye-care professionals, patients, patient advocacy groups, healthcare payors and the medical community.
Our potential products may not gain market acceptance among eye-care professionals, patients, patient advocacy groups, healthcare payors and the medical community. There are a number of available therapies marketed for the treatment of glaucoma and other diseases of the eye. Some of these drugs are branded and subject to patent protection, but most others, including latanoprost and many beta blockers, in the case of glaucoma treatment, are available on a generic basis. Many of these approved drugs are well established therapies and are widely accepted by eye-care professionals, patients and third-party payors. Insurers and other third-party payors may also encourage the use of generic products. The degree of market acceptance of our potential products will depend on a number of factors, including:
the market price, affordability and patient out-of-pocket costs of our potential products relative to other available products, which are predominantly generics;
the effectiveness of our potential products as compared with currently available products;
patient willingness to adopt our potential products in place of current therapies;
varying patient characteristics including demographic factors such as age, health, race and economic status;
changes in the standard of care for the targeted indications for any of our product candidates;
the prevalence and severity of any adverse effects;
limitations or warnings contained in a product candidate’s FDA-approved labeling;
limitations in the approved clinical indications and MOAs for our product candidates;
relative convenience and ease of administration;
the strength of our selling, marketing and distribution capabilities;
the quality of our relationships with eye-care professionals, patient advocacy groups, third-party payors and the medical community;
sufficient third-party coverage or reimbursement; and
potential product liability claims.
In addition, the potential market opportunity for our potential products is difficult to precisely estimate. Our estimates of the potential market opportunity for our potential products include several key assumptions based on our industry knowledge, industry publications, third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, independent sources have not verified all of our assumptions. If any of these assumptions proves to be inaccurate, then the actual market for our potential products could be smaller than our estimates of our potential market opportunity. If the actual market for our potential products is smaller than we expect, our product revenue may be limited, and it may be more difficult for us to achieve or maintain profitability. If we fail to achieve market acceptance of our potential products in the United States and abroad, our revenue will be more limited and it will be more difficult to achieve profitability.
If we fail to obtain and sustain an adequate level of reimbursement for our potential products by third-party payors, potential future sales would be materially adversely affected.
The course of treatment for glaucoma patients includes primarily older drugs, and the leading products for the treatment of glaucoma currently in the market, including latanoprost and timolol, are available as generic brands. There will be no commercially viable market for our potential products without reimbursement from third-party payors, and any reimbursement policy may be affected by future healthcare reform measures. We cannot be certain that reimbursement will be available for our potential products or any other product candidate we develop for glaucoma or other diseases of the eye. Additionally, even if

33



there is a commercially viable market, if the level of reimbursement is below our expectations, our anticipated revenue and gross margins will be adversely affected.
Third-party payors, such as government or private healthcare insurers, carefully review and increasingly question and challenge the coverage of and the prices charged for drugs. Reimbursement rates from private health insurance companies vary depending on the company, the insurance plan and other factors. Reimbursement rates may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. A current trend in the United States healthcare industry is toward cost containment. Large public and private payors, managed care organizations, group purchasing organizations and similar organizations are exerting increasing influence on decisions regarding the use of, and reimbursement levels for, particular treatments. Such third-party payors, including Medicare, may question the coverage of, and challenge the prices charged for, medical products and services, and many third-party payors limit coverage of or reimbursement for newly approved healthcare products. In particular, third-party payors may limit the covered indications. Cost-control initiatives could decrease the price we might establish for products, which could result in product revenues being lower than anticipated. We believe our drugs will be priced significantly higher than existing generic drugs and consistently with current branded drugs. If we are unable to show a significant benefit relative to existing generic drugs, Medicare, Medicaid and private payors may not be willing to reimburse for our drugs, which would significantly reduce the likelihood of them gaining market acceptance. Reimbursement systems in international markets vary significantly by country and by region, and reimbursement approvals must be obtained on a country-by-country basis. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted.
We expect that private insurers will consider the efficacy, cost effectiveness, safety and tolerability of our potential products in determining whether to approve reimbursement for such products and at what level. Obtaining these approvals can be a time consuming and expensive process. Our business would be materially adversely affected if we do not receive approval for reimbursement of our potential products from private insurers on a timely or satisfactory basis. Limitations on coverage could also be imposed at the local Medicare carrier level or by fiscal intermediaries. Medicare Part D, which provides a pharmacy benefit to Medicare patients as discussed below, does not require participating prescription drug plans to cover all drugs within a class of products. Our business could be materially adversely affected if Part D prescription drug plans were to limit access to, or deny or limit reimbursement of, our product candidates or other potential products.
Reimbursement in the European Union must be negotiated on a country-by-country basis and in many countries the product cannot be commercially launched until reimbursement is approved. The negotiation process in some countries can exceed 12 months. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our products to other available therapies. If the prices for our potential products decrease or if governmental and other third-party payors do not provide adequate coverage and reimbursement levels, our revenue, potential for future cash flows and prospects for profitability will suffer.
If we are found in violation of U.S. federal or state “fraud and abuse” laws or other healthcare laws and regulations, we may be required to pay a penalty and/or be suspended from participation in U.S. federal or state healthcare programs, which may adversely affect our business, financial condition and results of operation.
In the United States, our current and future arrangements with healthcare providers, healthcare organizations, third-party payors and customers expose us to broadly applicable anti-bribery, fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we are subject to variousresearch, market, sell and distribute our product candidates. Restrictions under applicable federal and state healthcare “fraudanti-bribery and abuse” laws, including anti-kickback laws, false claimshealthcare laws and other laws intended, among other things, to reduce fraud and abuse in federal and state healthcare programs. regulations, include the following:
The Federal Anti-Kickback Statute makes it illegal for any person, including a prescription drug manufacturer (or a party acting on its behalf), to knowingly and willfully solicit, receive, offer or pay any remuneration that is intended to induce the referral of business, including the purchase, order or prescription of a particular drug for which payment may be made under a federal healthcare program, such as Medicare or Medicaid. Although we seek to structure our business arrangements in compliance with all applicable requirements, these laws are broadly written, and it is often difficult to determine precisely how the law will be applied in specific circumstances. Accordingly, it is possible that our practices may be challenged under the Federal Anti-Kickback Statute.
The Federal False Claims Act prohibits anyone from, among other things, knowingly presenting or causing to be presented for payment to the government, including the federal healthcare programs, claims for reimbursed drugs or services that are false or fraudulent, claims for items or services that were not provided as claimed, or claims for medically unnecessary items or services. Many states have similar false claims laws. Cases have been brought under false claims laws alleging that off-label promotion of pharmaceutical products or the provision of kickbacks have resulted in the submission of false claims to governmental healthcare programs.
Under the Health Insurance Portability and Accountability Act of 1996, we are prohibited from knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors,payers, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services to obtain money or property of any healthcare benefit program.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including penalties, fines and/or exclusion or suspension from federal and state

34



healthcare programs such as Medicare and Medicaid and debarment from contracting with the U.S. government. In addition, private individuals have the ability to bring actions on behalf of the government under the Federal False Claims Act as well as under the false claims laws of several states.
In addition, certain manufacturers of covered drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program, with certain exceptions, are required to report annually to CMS information related to certain payments and other transfers of value to physicians and teaching hospitals, as well as ownership and investment interests held by the physicians described above and their immediate family members, with the information made publicly available on a searchable website. Effective January 1, 2022, transfers of value to physician assistants, nurse practitioners or clinical nurse specialists, certified registered nurse anesthetists, and certified nurse-midwives must also be reported.
Many states have adopted laws similar to the Federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source, not just governmental payors.payers. In addition, some states have passed laws that require pharmaceutical companies to comply with the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America’s Code on Interactions with Healthcare Professionals. Several states also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state. There are ambiguities as to what is required to comply with these state requirements and if we fail to comply with an applicable state law requirement we could be subject to penalties.
Furthermore, the government purchasing and reimbursement programs include remedies such as the obligation to correct reported prices and pay additional rebates (depending on the direction of the correction) or pay restitution to the extent the government overpaid for covered drugs, In addition, federal law provides for civil monetary penalties for conduct such as failure to provide required information, late submission of required information, false information, and knowingly and intentionally overcharging a 340B covered entity.
Neither the government nor the courts have provided definitive guidance on the application of fraud and abuse laws to our business. Law enforcement authorities are increasingly focused on enforcing these laws, and it is possible that some of our practices may be challenged under these laws. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. While we believe we have structured our business arrangements to comply with these laws, it is possible that the government could allege violations of, or convict us of violating, these laws. If we are found in violation of one of these laws, we could be subject to significant civil, criminal and administrative penalties, damages, fines, exclusion from governmental funded federal or state healthcare programs and the curtailment or restructuring of our operations. Were this to occur, our business, financial condition and results of operations and cash flows may be materially adversely affected.
Recently enactedExisting and future legislation may increase the difficulty and cost of commercializing our potential products and may affect the prices we may obtain.
In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay regulatory approval of our potential products, restrict or regulate post-marketing activities and affect our ability to profitably sell our potential products for which we obtain regulatory approval.
In the United States, the MMA changed the way Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the elderly by establishing Medicare Part D and introduced a reimbursement methodology based on average sales prices for physician-administered drugs under Medicare Part B. In addition, this legislation provided authority for limiting the number of drugs that are covered in any therapeutic class under the Part D program. Cost reduction initiatives and other provisions of this legislation could decrease the coverage and reimbursement rate that we receive for any of our approved products. While the MMA only applies to drug benefits for Medicare beneficiaries, private payorspayers often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors.payers.
In March 2010, President Obama signed into law the PPACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against healthcare fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Among other things, PPACA increased manufacturers’ rebate liability under the Medicaid Drug Rebate Program, by increasing the minimum rebate amount for both branded and generic drugs and revised the definition of “average manufacturer price,” or AMP, which may also increase the amount of Medicaid drug rebates manufacturers are required to pay to states. The legislation also expanded Medicaid drug rebates, which previously had been payable only on fee-for-service utilization, to Medicaid managed care utilization, and created an alternative rebate formula for certain new formulations of certain existing products that is intended to increase the rebates due on those drugs. The Centers for Medicare & Medicaid Services, which administers the Medicaid Drug Rebate Program, also expanded Medicaid rebates to the utilization that occurs in the territories of the United States, such as Puerto Rico and the Virgin Islands, effective April 1, 2017. Further, beginning in 2011, PPACA imposed a significant annual fee on companies that manufacture or import branded prescription drug

products and requiresrequired manufacturers to provide a 50% discount off the negotiated price of prescriptions filled by beneficiaries in the Medicare Part D coverage gap, referred to as the “donut hole.hole,Substantial new provisions affecting compliancewhich was increased to 70% of the negotiated price beginning in 2019. There have also been enacted,efforts by the Trump Administration and Congress to seek to repeal all or portions of PPACA, and in December 2017, President Trump signed into law the Tax Act (as defined herein), which eliminated certain requirements of PPACA, including the individual mandate. There is uncertainty with respect to the impact these or future changes, if any, may require ushave.
In addition, the Trump Administration has indicated an intent to modify our business practicesaddress prescription drug pricing and recent Congressional hearings have brought increased public attention to the costs of prescription drugs. The Trump Administration has proposed a regulation intended to eliminate the rebate-oriented model used for pricing pharmaceutical products under Medicare Part D and Medicaid Managed Care, with healthcare practitioners. For example, pharmaceutical companiesthe policy objective of lower costs to consumers. If this proposal is finalized, a similar approach may be adopted by commercial insurance plans as well. In addition, the Trump Administration has made other proposals that are requiredin earlier stages. Numerous bills have been introduced in Congress by members of both parties seeking to track certain payments made to physicians and teaching hospitals,reduce drug prices using a variety of approaches. These actions and the first reports were due in 2014uncertainty about the future of the PPACA and the reported information was made publicly available on a searchable website in September 2014. We will not know the full effects of PPACA until applicable federal and state agencies issue regulations or guidance under the new law. Although it is too early to determine the full effect of PPACA, the new law appearshealthcare laws are likely to continue the downward pressure on

35



pharmaceutical pricing especially under the Medicare program, and may also increase our regulatory burdens and operating costs. While we currently do not believe the implementation of any such initiatives would negatively impact our net sales or operating margins, these initiatives are in early stages.
Legislative and regulatory proposals have been introduced at both the state and federal level to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We are not sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any,potential products may be. While we may establish procedures to react to the current laws and regulations, one or more laws or regulations may be enacted that will require us to alter or refresh our existing procedures. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing approval testing and other requirements.
If we face allegations of noncompliance with the law and encounter sanctions, our reputation, revenues and liquidity may suffer, and our potential productsRhopressa® or RocklatanTM or any future product candidates, if approved, could be subject to restrictions or withdrawal from the market.
Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenues from our potential products.revenues. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating results will be materially adversely affected. Additionally, if we are unable to generate revenues from our product sales, our potential for achieving profitability will be diminished and the need to raise capital necessary to fund our operations will be increased.
If ourRhopressa® and RocklatanTM and any future product candidates, receive regulatory approval, we will beif approved, subject us to ongoing regulatory requirements and we may face future development, manufacturing and regulatory difficulties.
OurRhopressa® is, and RocklatanTM or any future product candidates, if approved, will also be, subject to ongoing regulatory requirements for labeling, packaging, storage, advertising, promotion, sampling, record-keeping, submission of safety and other post- marketpost-market approval information, importation and exportation. In addition, approved products, manufacturers and manufacturing facilities are required to comply with extensive FDA and EMA requirements and the requirements of other similar agencies, including ensuring that quality control and manufacturing procedures conform to cGMP requirements. As such, we and our potential future contract manufacturers will beare subject to continual review and periodic inspections to assess compliance with cGMPs. Accordingly, we and others with whom we work will beare required to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control. We willare also be required to report certain adverse reactions and production problems, if any, to the FDA and the EMA and other similar agencies and to comply with certain requirements concerning advertising and promotion for our potential products.promotion. Promotional communications with respect to prescription drugs also are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. Accordingly, once approved, we may not promote our products, if any product for indications, uses or claims for which they are not approved.approved, even though physicians may prescribe them for those uses. If we want to expand any such indications for which we may market a product, we will need to obtain additional regulatory approvals, which may not be granted.

If a regulatory agency discovers previously unknown problems with aRhopressa® or RocklatanTM or any future product candidates, if approved, such as adverse events of unanticipated severity or frequency, or problems with the facility where thesuch product is manufactured, or disagrees with the promotion, marketing or labeling of asuch product, or finds that we have engaged in the promotion of off-label use, it may impose restrictions on that product or us, including requiring withdrawal of the that

product from the market. If our potential productsRhopressa® or RocklatanTM or any future product candidates, if approved, fail to comply with applicable regulatory requirements, a regulatory agency may:
issue warning letters or untitled letters;
require product recalls;
mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;
require us or our potential future collaborators to enter into a consent decree or permanent injunction, which can include shutdown of manufacturing facilities, imposition of various fines, reimbursements for inspection costs, required due dates for specific actions and penalties for noncompliance;
impose other administrative or judicial civil or criminal penalties or pursue criminal prosecution;
withdraw regulatory approval;
refuse to approve pending applications or supplements to approved applications filed by us or by our potential future collaborators;
impose restrictions on operations, including costly new manufacturing requirements; or
seize or detain products.

We may not be able to identify additional therapeutic opportunities for our potentialRhopressa®, RocklatanTM or any future product candidates or to expand our portfolio of product candidates.
We maycontinue to explore other therapeutic opportunities in ophthalmology through internal research programs and from time to time we may explore such opportunities through research collaboration arrangements or acquisitions and may seek to commercialize a portfolio of new ophthalmic drugs or technologies in addition to Rhopressa® and RocklatanTM. For example, in 2017, we entered into a collaboration arrangement with DSM, which was expanded in the third quarter of 2018, and acquired the rights to certain assets from Envisia, both of which are expected to support the development of our ongoing preclinical retinal programs. In addition to our preclinical retinal programs, we are conducting preclinical studies to evaluate potential additional indications for Rhopressa® and potentially RocklatanTM. We are also evaluating our owned library of ROCK inhibitors for potential indications beyond ophthalmology. Our clinical operations to date have been limited to developing product candidates for the treatment of glaucoma and ocular hypertension, and there can be no assurance that we will successfully develop, license or acquire any drugs or technologies in new therapeutic areas or at all.
Preclinical studies require additional research and development, which in some cases may include significant preclinical, clinical and other testing, prior to initiating clinical development or seeking regulatory approval to market new indications, technologies and/or product candidates. Accordingly, these additional indications, technologies and product candidates will not be commercially available for a number of years, if at all. In particular, although we are currently developing.exploring additional indications for Rhopressa®, we cannot guarantee that we will pursue or receive the regulatory approvals required to promote Rhopressa®for any additional indications. Failure to receive such approvals will prevent us from promoting and commercializing Rhopressa®beyond its currently approved indication.
Research programs, including through collaboration arrangements, to pursue the development of our Rhopressa®, RocklatanTM and any futureproduct candidates for additional indications and to identify new product candidates, technologies, therapeutic areas and disease targets require substantial technical, financial and human resources whether or not we ultimately are successful. Our research programs may initially show promise in identifying potential additional indications, technologies, therapeutic areas and/or product candidates, yet fail to yield results for clinical development for a number of reasons, including:
the research methodology used may not be successful in identifying potential additional indications, technologies, therapeutic areas and/or product candidates;
potential additional indications, technologies, therapeutic areas or product candidates may, after further study, fail to demonstrate efficacy sufficient to warrant further clinical development;
potential technologies or product candidates may, after further study, be shown to be ineffective or have harmful adverse effects or other characteristics that indicate they are unlikely to be effective drugs; or
it may take greater human and financial resources to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates or technologies, whether through internal research programs,

research collaboration arrangements or acquisitions, than we will possess, thereby limiting our ability to diversify and expand our product portfolio.
BecauseWe are currently developing two preclinical sustained-release implants focused on retinal diseases. AR-13503, for which we expect to submit an IND in the first quarter of 2019, and AR-1105, for which we submitted an IND in the fourth quarter of 2018. The IND for AR-1105 was accepted for review by the FDA, and we expect to initiate a Phase 2 clinical study later in the first quarter of 2019. The decision whether to pursue, and the timing of, any additional preclinical research programs is subject to a number of factors and we may suspend or discontinue research programs at any time.
In addition, because we have limited financial and managerial resources, we focus on research programs and product candidates for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities.
Accordingly, there can be no assurance that we will ever be able to identify or develop additional therapeutic opportunities for ourRhopressa® or RocklatanTM or any future product candidates or any uses for our existing proprietary compounds beyond glaucoma or to develop suitable potential product candidates or technologies through internal research programs, research collaboration arrangements or acquisitions, which could materially adversely affect our future growth and prospects.
Our current product candidatesRhopressa® and RocklatanTM are all designed to treat patients with open-angle glaucoma or ocular hypertension, and the success or failure of any oneeither of our product candidatesthem could impact sales of ourthe other or other potential ROCK inhibitor products in the future.
Our current product candidatesRhopressa® and RocklatanTM are designed to be once-daily dosed ROCK inhibitor eye drops to be applied topically to lowerreduce IOP for the treatment of glaucoma through various MOAs. Accordingly, increased salesor ocular hypertension. While we believe there is space for one of our potential products may negatively impact sales for our other potential products. Our commercialization strategy is unique for each of our product candidates. However,both Rhopressa® and RocklatanTM, we cannot guarantee that cannibalization of sales among our potential product lines will not occur in the future. While increased sales for one of Rhopressa® or RocklatanTM, if approved, may negatively impact sales for the other, our commercialization strategy is unique for each. Because each of our current product candidatesRhopressa® and RocklatanTM are ROCK inhibitor eye drops designed to treat patients with glaucoma or ocular hypertension, any challenges or failures with respect to anyeither of these potential productsRhopressa® and RocklatanTM could negatively impact sales or the public perception of ourthe other or any other potential products.ROCK inhibitor products we may develop in the future.
Risks Related to Our Financial Position and Need for Additional CapitalManufacturing
We currently have no source of revenue and may never become profitable.
We are a clinical-stage pharmaceutical company with a limited operating history. Our ability to generate revenue and become profitable depends upon our ability to successfully complete the development of our product candidates for the management of glaucoma and obtain the necessary regulatory approvals for our product candidates. We have never been profitable, have no products approved for commercial sale and to date have not generated any revenue from product sales. Even if we receive regulatory approval for our product candidates for commercial sale, we do not know when such potential products will generate revenue, if at all. Our ability to generate product revenue depends on a number of factors, including our ability to:
successfully complete clinical development, and receive regulatory approval, for our product candidates;
set an acceptable price for our potential products and obtain adequate reimbursement from third-party payors;
obtain or manufacture commercial quantities of our potential products at acceptable cost levels; and
successfully market and sell our potential products in the United States and abroad.
In addition, because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. In addition, our expenses could increase beyond expectations if we are required by the FDA or other regulatory authorities to perform studies in

37



addition to those that we currently anticipate. Even if our product candidates are approved for commercial sale, we anticipate incurring significant costs associated with the commercial launch of these product candidates.
Our ability to become and remain profitable depends on our ability to generate revenue. Even if we are able to generate revenues from the sale of our potential products, we may not become profitable and may need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce our operations. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, expand our business or continue our operations.

We have incurred net losses since inception and anticipate that we will continue to incur net losses for the foreseeable future.
We have incurred losses in each year since our inception in June 2005. Our net losses were $74.4 million, $48.1 million and $31.1 million for the years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015, we had an accumulated deficit of $217.6 million.
Investment in pharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a product candidate will fail to gain regulatory approval or become commercially viable. We have devoted the majority of our financial resources to research and development, including our non-clinical development activities and clinical trials. To date, we have financed our operations primarily through the sale of equity securities and issuance of convertible debt, including the completion of our IPO in October 2013, the issuance of the 2014 Convertible Notes in September 2014 and the issuance and sale of common stock pursuant to our “at-the-market” sales agreements. Our product candidates will require the completion of regulatory review, significant marketing efforts and substantial investment before they can provide us with any revenue.
We expect our research and development expenses to continue to be significant in connection with our ongoing and planned Phase 3 registration trials. In addition, if we obtain regulatory approval for our product candidates, we expect to incur increased sales and marketing expenses. As a result, we expect to continue to incur significant and increasing operating losses and negative cash flows for the foreseeable future. These losses have had and will continue to have a material adverse effect on our stockholders’ equity (deficit), financial position, cash flows and working capital.
We may need to obtain additional financing to fund our operations and, if we are unable to obtain such financing, we may be unable to complete the development and commercialization of our primary product candidates.
Our operations have consumed substantial amounts of cash since inception. In October 2013, we received net proceeds from our IPO of approximately $68.3 million, after deducting underwriting discounts and commissions and expenses. Since our IPO, we have raised additional net proceeds of approximately $122.9 million from the issuance of the 2014 Convertible Notes and approximately $50.5 million through “at-the-market” sales during 2015. We may need to obtain additional financing to fund our future operations. Additionally, we may need to obtain additional financing to conduct additional trials for the approval of our drug candidates if requested by regulatory bodies, and completing the development of any additional product candidates we might acquire. Moreover, our fixed expenses such as rent and other contractual commitments are substantial and are expected to increase in the future.
Our future funding requirements will depend on many factors, including, but not limited to:
the progress, timing, scope and costs of our clinical trials, including the ability to timely enroll patients in our planned and potential future clinical trials;
the time and cost necessary to obtain regulatory approvals that may be required by regulatory authorities;
the time and cost necessary to establish internal manufacturing capabilities, if any, or arrangements with third-party manufacturers;
our ability to successfully commercialize our product candidates;
the amount of sales and other revenues from product candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate third-party reimbursement;
selling and marketing costs associated with our potential products, including the cost and timing of expanding our marketing and sales capabilities;

38



the terms and timing of any collaborations, licensing or other arrangements that we may establish;
cash requirements of any future acquisitions and/or the development of other product candidates;
the costs of operating as a public company;
the time and cost necessary to respond to technological and market developments; and
the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.
Until we can generate a sufficient amount of revenue, we may finance future cash needs through public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances and marketing or distribution arrangements. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization efforts. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. In addition, if we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or to grant licenses on terms that may not be favorable to us.
We believe that our existing cash and cash equivalents and investments and any future sales under our current “at-the-market” sales agreements will be sufficient to complete all currently known non-clinical and clinical requirements for our development programs advancing RhopressaTM and RoclatanTM, approval by the FDA and product commercialization, pending successful outcome of the trials. However, until we can generate a sufficient amount of revenue, we may be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. Our forecast of the period of time through which our financial resources will be adequate to support our operating requirements is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on a number of assumptions that may prove to be wrong, and changing circumstances beyond our control may cause us to consume capital more rapidly than we currently anticipate. Our inability to obtain additional funding when we need it could seriously harm our business.
Our substantial leverage and related obligations could adversely affect our financial condition and restrict our operating flexibility.
We have substantial debt and related obligations. As of December 31, 2015, our total indebtedness consisted of our $125.0 million aggregate principal amount of 2014 Convertible Notes. Our substantial level of debt and related obligations, including interest payments, covenants and restrictions, could have important consequences, including the following:
impairing our ability to successfully complete the development of our product candidates, which would prevent us from generating a source of revenue and becoming profitable;
making it more difficult for us to satisfy our obligations with respect to our indebtedness, which could result in an event of default under the agreement governing the 2014 Convertible Notes;
limiting our ability to obtain additional financing on satisfactory terms to fund our working capital requirements, capital expenditures, acquisitions, debt obligations and other general corporate requirements;
increasing our vulnerability to general economic downturns, competition and industry conditions, which could place us at a competitive disadvantage compared to our competitors that are less leveraged and therefore we may be unable to take advantage of opportunities that our leverage prevents us from exploiting; and
imposing additional restrictions on the manner in which we conduct our business, including restrictions on our ability to pay dividends, incur additional debt and sell assets.

The occurrence of any one of these events could have an adverse effect on our business, financial condition, operating results or cash flows and ability to satisfy our obligations under our indebtedness.
Although the agreement governing the 2014 Convertible Notes contains restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and any indebtedness

39



incurred in compliance with these restrictions could be substantial. In addition, the agreement governing the 2014 Convertible Notes allows us to incur a significant amount of indebtedness in connection with acquisitions and a significant amount of purchase money debt. If new debt is added to current debt levels, the related risks that we and noteholders face would be increased.
The terms of the agreement governing the 2014 Convertible Notes may restrict our current and future operations, particularly our ability to respond to changes in our business or to take certain actions.
The agreement governing the 2014 Convertible Notes contains, and the terms of any future indebtedness of ours would likely contain, a number of restrictive covenants that impose significant operating restrictions, including restrictions on our ability to engage in acts that may be in our best long-term interests. The agreement governing the 2014 Convertible Notes includes covenants that, among other things, restrict or otherwise limit our ability to:
incur additional indebtedness and create liens;
pay dividends on capital stock and make other restricted payments;
enter into any merger, partnership, joint venture, syndicate, pool, profit-sharing or royalty agreement, or engage in any transactions with our affiliates;
sell or transfer assets;
merge; and
issue equity securities senior to our common stock or convertible or exercisable for equity securities senior to our common stock.
If not cured, as applicable, a breach of any of these provisions could result in a default under the agreement governing the 2014 Convertible Notes that would allow noteholders to declare the outstanding debt immediately due and payable. In addition, the 2014 Convertible Notes are secured by substantially all of our existing and hereafter created or acquired assets, including our intellectual property, accounts receivable, equipment, general intangibles, inventory and investment property, and all of the proceeds and products of the foregoing. If we are unable to pay those amounts because we do not have sufficient cash on hand or are unable to obtain alternative financing on acceptable terms, the noteholders could initiate a bankruptcy proceeding or proceed against any assets that serve as collateral to secure the 2014 Convertible Notes.
These restrictions could limit our ability to obtain future financings, make needed capital expenditures, withstand future downturns in the economy or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of limitations imposed on us by the restrictive covenants under the 2014 Convertible Notes.
We may sell additional equity or debt securities to fund our operations, which may result in dilution to our stockholders and impose restrictions on our business.
In order to raise additional funds to support our operations, we may sell additional equity or debt securities, which would result in dilution to all of our stockholders or impose restrictive covenants that adversely impact our business. The incurrence of indebtedness would result in increased fixed payment obligations and could also result in restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected.
Our short operating history may make it difficult for investors to evaluate the success of our business to date and to assess our future viability.
We are a clinical-stage company. We were incorporated and commenced active operations in the second quarter of 2005. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital and developing our product candidates. We have not yet demonstrated our ability to successfully complete a Phase 3 program, obtain regulatory approval, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history.

40



In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will need to transition from a company with a product development focus to a company capable of supporting commercial activities. We may not be successful in such a transition.
Determining our income tax rate is complex and subject to uncertainty.
The computation of income tax provisions is complex, as it is based on the laws of numerous taxing jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provisions under U.S. GAAP. Our provision for income tax can be materially impacted, for example, by the geographical mix of our profits and losses, changes in our business, such as internal restructuring and acquisitions, changes in tax laws and accounting guidance and other regulatory, legislative or judicial developments, tax audit determinations, changes in our uncertain tax positions, changes in our intent and capacity to permanently reinvest foreign earnings, changes to our transfer pricing practices, tax deductions attributed to equity compensation and changes in our need for a valuation allowance for deferred tax assets. For these reasons, our actual income taxes may be materially different than our provision for income tax.
Our ability to use our net operating loss carry-forwards may be limited.
If we experience an “ownership change” for purposes of Section 382 of the Internal Revenue Code of 1986, as amended (Section 382), or similar state provisions, we may be subject to annual limits on our ability to utilize net operating loss carry-forwards. An ownership change is, as a general matter, triggered by sales or acquisitions of our stock in excess of 50% on a cumulative basis during a three-year period by persons owning 5% or more of our total equity value. As of December 31, 2015, we had federal and state net operating losses of approximately $61.1 million which begin to expire at various dates beginning in 2024, if not utilized. Certain transactions occurred in 2015 and prior years that resulted in ownership changes as defined under Section 382 and similar state provisions, which will limit the future use of certain federal and state net operating loss carry-forwards. Those federal and state net operating losses that are not limited are included as deferred tax assets and have been fully offset by a valuation allowance as of December 31, 2015.
The enactment of legislation implementing changes in the U.S. taxation of international business activities or the adoption of other tax reform policies could materially impact our financial position and results of operations.
Recent changes to U.S. tax laws, including limitations on the ability of taxpayers to claim and utilize foreign tax credits, as well as changes to U.S. tax laws that may be enacted in the future, could impact the tax treatment of our potential future foreign earnings. Due to the expansion of our international business activities, any changes in the U.S. taxation of such activities may increase our worldwide effective tax rate and adversely affect our financial position and results of operations.
Our international operations subject us to potentially adverse tax consequences.

We generally conduct our international operations through wholly-owned subsidiaries and report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates and reduced cash flows.
Risks Related to Our Reliance on Third Parties
We currently have no manufacturing capacity and anticipate continued reliance on third-party manufacturers for the development and commercialization of ourRhopressa®, RocklatanTM and any future product candidates in accordance with manufacturing regulations until we have completely developed our internal manufacturing capabilities, if at all.
We do not currently operate manufacturing facilities for clinical or commercial production of Rhopressa®, RocklatanTM and any future product candidates, other than AR-13503 and AR-1105. We currently lack the resources and the capabilities to manufacture Rhopressa®, RocklatanTM and any future product candidates, other than AR-13503 and AR-1105, on a clinical or commercial scale.
With respect to the commercial production of Rhopressa®, we currently are outsourcing the production of the API and final drug product until such a time when we can develop internal manufacturing capabilities, if at all.
We do not currently operatehave entered into a contractual relationship for drug product manufacturing facilities for clinical orthe commercialization of Rhopressa®, and we are working to establish an additional contractual relationship for the commercial production of our product candidates. We have no experience in drug formulation,Rhopressa®.This process is difficult and time consuming and we lack the resources and the capabilities to manufacture our product candidates and potential products on a clinical orcan give no assurance that we will enter any future commercial scale. We currently rely on third-party manufacturers to produce the active pharmaceutical ingredient and final drug product for our clinical trials. We manage such production with all our vendors on a purchase order basis in accordance with applicable master service and supply agreements. We do not have long-term agreements with any of theseadditional manufacturers on favorable terms or any other third-party suppliers to support our clinical trials. at all.
To the extent we terminate our existing supplier arrangements in the future and seek to enter into arrangements with alternative suppliers, we might experience a delay in our ability to obtain our clinical or commercial supplies.

41



With respectOur current manufacturing capability is limited to production of our potential commercial products in the future, if and when our product candidates are approved for marketing by the applicable regulatory authorities, we plan to outsource the production of the active pharmaceutical ingredients and finalclinical product manufacturing until such a time when we can develop internal manufacturing capabilities, if at all. We have entered into a contractual relationshipsupply necessary for Aerie’s two lead development programs focused on retinal diseases for the final commercial drug product manufacturing. However, we do not have any current contractual relationshipspreclinical sustained-release implants AR-13503 and AR-1105. We commenced operation of our cGMP-validated manufacturing facility for the commercial production of ophthalmic implants using the active pharmaceutical ingredients.proprietary PRINT® technology platform in the fourth quarter of 2018. This processfacility is difficultcurrently only being used to support clinical trials of AR-13503 and time consuming AR-1105 implants. This facility is not being used to produce commercial or clinical supply of Rhopressa® or RocklatanTM.
In January 2017, we commenced establishment of our own manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, which is expected to produce commercial supplies of Rhopressa® and, weif approved, RocklatanTM,

Rhokiinsa® and RoclandaTM. We expect that commercial supply from the plant will be available in early 2020. However, there can givebe no assurance that we will enterbe able to develop the manufacturing capabilities required to produce our final drug product on a commercial scale or in accordance with manufacturing regulations. See “—We have no experience developing manufacturing facilities or manufacturing Rhopressa® or RocklatanTM and we cannot assure you that we will be able to develop our manufacturing plant or manufacture Rhopressa® or RocklatanTM in compliance with regulations at a cost or in quantities necessary to make them commercially viable.” If our manufacturing operations fail to achieve regulatory approval or to effectively produce commercial supplies of Rhopressa® or RocklatanTM or any future product candidates, if approved, or until such time we are capable of developing internal manufacturing capabilities, we will be required to rely solely on third-party manufacturers to meet our commercial supply agreements with any manufacturers on favorable termsmanufacturing needs, which may materially adversely affect our business, results of operations or at all.financial condition.
Reliance on third-party manufacturers entails risks, including:
manufacturing delays if our third-party manufacturers give greater priority to the supply of other products over our third-party manufacturers give greater priority to the supply of other products over Rhopressa® or RocklatanTM or any future product candidates, if approved, or otherwise do not satisfactorily perform according to the terms of their agreements with us;
delays in obtaining regulatory approval for Rhopressa® outside the United States or for RocklatanTM or any future product candidates, if our third-party manufacturers fail to satisfy or comply with regulatory requirements;
the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us;
the possible breach of the manufacturing agreement by the third party;
product loss due to contamination, equipment failure or improper installation or operation of equipment or operator error;
the failure of the third-party manufacturer to comply with applicable regulatory requirements; and
the possible misappropriation of our proprietary information, including our trade secrets and know-how.
OurFor example, in October 2016, we were required to withdraw the initial submission of our NDA for Rhopressa® due to a contract manufacturer of our drug product not being prepared for pre-approval inspection by the FDA. We resubmitted the Rhopressa® NDA in February 2017 upon receiving confirmation from the contract manufacturer that it was prepared for FDA inspection and the Rhopressa® NDA was subsequently approved in December 2017.
In addition, our manufacturers may not perform as agreed or may not remain in the contract manufacturing business. In the event of a natural disaster, business failure, strike or other difficulty, we may be unable to replace a third-party manufacturer in a timely manner and the production of ourRhopressa®, RocklatanTM or any future product candidates and potential products could be interrupted, resulting in delays and additional costs. We may also have to incur other charges and expenses for products that fail to meet specifications and undertake remediation efforts.

If we or third-party manufacturers fail to comply with manufacturing regulations, our financial results and financial condition will be adversely affected.
Before we or a third party can begin commercial manufacture of ourRhopressa® or RocklatanTM or any future product candidates, and potential products,if approved, we or the third party must obtain regulatory approval of our or their manufacturing facilities, processes and quality systems. If our third-party manufacturers do not have a cGMP compliance status acceptable to the FDA, approval of any NDA that includes those third-party manufacturers will be delayed.
Due to the complexity of the processes used to manufacture pharmaceutical products and product candidates, we or any potential third-party manufacturer may be unable to initially pass federal, state or international regulatory inspections in a cost effectivecost-effective manner. We or certain of our contract manufacturers may fail to satisfy or comply with manufacturing regulations. If we or our contract manufacturers aredo not approved byhave a compliance status acceptable to the FDA, ourregulatory approval and/or commercial supply of drug substancethe active pharmaceutical ingredients of Rhopressa® or RocklatanTM or any future product candidates, if approved, will be significantly delayed and may result in significant additional costs.
In addition, pharmaceutical manufacturing facilities are continuously subject to inspection by the FDA and foreign regulatory authorities, before and after product approval, and must comply with cGMP. We or our contract manufacturers may encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. In addition, failure to achieve and maintain high manufacturing standards in accordance with applicable regulatory requirements, or the

incidence of manufacturing errors, could result in patient injury, product liability claims, product shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously harm our business. If we or a third-party manufacturer with whom we contract is unable to comply with manufacturing regulations, we may be subject to fines, unanticipated compliance expenses, recall or seizure of our products, product liability claims, total or partial suspension of production and/or enforcement actions, including injunctions and criminal or civil prosecution. These possible sanctions could materially adversely affect our reputation, financial results and financial condition.
Furthermore, changes in the manufacturing process or procedure, including a change in the location where the product is manufactured or a change of a third-party manufacturer, will require prior FDA or other regulatory review and/or approval of the manufacturing process and procedures in accordance with the FDA’s regulations or comparable foreign requirements. This review may be costly and time consuming and could delay or prevent the launch or commercial production of a product. The new facility will also be subject to pre-approval inspection. In addition, we have to demonstrate that the product made at the new facility is equivalent to the product made at the former facility by physical and chemical methods, which are costly and time consuming. It is also possible that the FDA may require clinical testing as a way to prove equivalency, which would result in additional costs and delay.

We have no experience developing manufacturing facilities or manufacturing Rhopressa® or RocklatanTM, and we cannot assure you that we will be able to develop our manufacturing plant or manufacture Rhopressa® or RocklatanTM in compliance with regulations at a cost or in quantities necessary to make them commercially viable.

TableWe are in process of Contentsestablishing our own manufacturing plant in Athlone, Ireland, for the future commercial production of Rhopressa® and, if approved, RocklatanTM, Rhokiinsa® and RoclandaTM. We expect that commercial supply from the plant will be available in early 2020. We have no experience in developing manufacturing facilities or manufacturing drug products. We will need to hire and train significant numbers of qualified employees to staff this facility. There can be no assurance that we will develop a manufacturing plant that is adequate to produce materials for commercial use on our expected timing or at all.
The development of manufacturing facilities and the manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. The equipment and facilities employed in the manufacture of pharmaceuticals are subject to stringent qualification requirements by regulatory agencies, including validation of facility, equipment, systems, processes and analytics. We may be subject to lengthy delays and expense in conducting validation studies, if we can meet the requirements at all. Although we expect to complete internal construction of the plant to meet these qualification requirements, there can be no assurance that we will obtain permission or approval from the FDA and other regulatory authorities to allow the plant to manufacture Rhopressa® and RocklatanTM, if approved, for export to the United States and other markets. If we are unable to obtain such permission or approval in a timely manner, our ability to successfully manufacture and commercialize Rhopressa® and RocklatanTM, if approved, may be harmed.
In addition, we will be subject to customary risks associated with the construction of manufacturing plants, including, design defects, construction cost overruns (including labor and materials) and other factors that may delay build-out of the manufacturing plant. Our manufacturing operations and those of our third-party suppliers are subject to environmental, health and safety laws and regulations concerning, among other things, the use, storage, generation, handling, transportation and disposal of hazardous substances or wastes, the cleanup of hazardous substance releases, exposure to hazardous substances and emissions or discharges into the air or water. Violations of these laws and regulations can result in significant business interruptions and/or civil and criminal penalties. New laws and regulations, violations of or amendments to existing laws or regulations, or stricter enforcement of existing requirements, could require us to incur material costs, subject us to new or increased liabilities, and cause disruptions to our manufacturing activities that could be material. If the cost of funding the build-out of our manufacturing plant exceeds budgeted amounts and/or the time period for construction is longer than initially anticipated, our business, results of operations and financial condition could be materially adversely affected. Similarly, if we cannot access the capital we need to fund our operations, we may need to postpone or cancel the construction of the manufacturing plant or other components of our business strategy, which could impair our ability to compete effectively and harm our business, financial condition and results of operations.
Manufacturers of pharmaceutical products often encounter difficulties in production, especially in scaling up initial production. These problems include difficulties with production costs and yields, quality control and assurance and shortages of qualified personnel, as well as compliance with strictly enforced regulations. If we are unable to obtain certification from the FDA and other regulatory authorities or effectively produce commercial supplies of Rhopressa® and RocklatanTM, if approved, we will be required to rely on a third-party manufacturer to meet our commercial manufacturing needs, which may materially adversely affect our business, results of operations and financial condition. See “—We currently have limited manufacturing capacity and anticipate continued reliance on third-party manufacturers for the development and commercialization of Rhopressa®, RocklatanTM and any future product candidates in accordance with manufacturing regulations until we have completely developed our internal manufacturing capabilities, if at all.”


Any of these risks could entail higher costs, cause us to delay production and may result in our being unable to effectively support commercialization of Rhopressa® and RocklatanTM, if approved. Furthermore, if we obtain regulatory approval and fail to deliver the required commercial quantities of product on a timely basis, and at commercially reasonable prices and acceptable quality, we would likely be unable to meet demand, if any, for Rhopressa® and RocklatanTM, if approved, and we would lose potential revenues.
Risks Related to Our Financial Position and Need for Additional Capital
We have recently begun commercializing Rhopressa®, our first FDA-approved product, have limited revenue and may never become profitable.
We have a limited operating history and have only recently begun commercializing our first product, Rhopressa®. We have never been profitable and only have one product approved for commercial sale. Even though we received FDA approval for Rhopressa® and began commercial sales in the United States, we are still in the process of obtaining regulatory approval in jurisdictions outside the United States and there is no guarantee that Rhopressa® will be approved in any such jurisdictions. We do not have regulatory approval for RocklatanTM or any future product candidates in any jurisdiction. FDA approval of Rhopressa® does not guarantee FDA approval of RocklatanTM or any future product candidates and also does not guarantee regulatory approval of Rhopressa® in jurisdictions outside the United States.
Our ability to generate product revenue depends on a number of factors, including our ability to:
maintain an acceptable price for Rhopressa® in the United States and set an acceptable price for Rhopressa® in jurisdictions outside the United States, if approved, and obtain adequate reimbursement from third-party payers in jurisdictions outside the United States;
set an acceptable price for RocklatanTM and any future product candidates, if approved, and obtain adequate reimbursement from third-party payers;
manufacture or obtain commercial quantities of Rhopressa® and RocklatanTM and any future product candidates, if approved, at acceptable cost levels;
successfully market and sell Rhopressa® and RocklatanTM and any future product candidates, if approved, in the United States and other jurisdictions; and
successfully complete clinical development, and receive regulatory approval, for our current collaboration arrangementand any future product candidates.
In addition, because of the numerous risks and uncertainties associated with product development, commercialization and manufacturing, we are unable to precisely predict the timing or collaboration arrangementamount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. In addition, our expenses could increase beyond expectations for a number of reasons, including if we are required by the FDA or other regulatory authorities to perform studies in addition to those that we currently anticipate. Even though we have begun commercial sales of Rhopressa®, we are still incurring and anticipate continuing to incur significant costs associated with the commercialization of Rhopressa® and commercial launch of RocklatanTM, if approved.
Our ability to become and remain profitable depends on our ability to generate revenue. Although we have generated revenues from the sale of Rhopressa®, even if we are able to generate revenues from RocklatanTM and any future product candidates, if approved, we may enter into in the futurenot become profitable and may need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce our operations. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could materially impair our ability to raise capital, expand our business or continue our operations.
We have incurred net losses since inception and anticipate that we will continue to incur net losses until such a time when Rhopressa® and RocklatanTM, if approved, are commercially successful, if at all.
We have incurred losses in each year since our inception in June 2005. Our net losses were $232.6 million, $145.1 million and $99.1 million for the years ended December 31, 2018, 2017 and 2016, respectively. As of December 31, 2018, we had an accumulated deficit of $696.4 million.

Investment in pharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a product candidate will fail to gain regulatory approval or become commercially viable. We have devoted the majority of our historical financial resources to research and development, including our non-clinical development activities and clinical trials. To date, we have financed our operations primarily through the sale of equity securities and issuance of convertible debt, including the completion of our IPO in October 2013, the issuance of the 2014 Convertible Notes in September 2014, which were converted into shares of common stock in July 2018, and the issuance and sale of common stock pursuant to our registration statements on Form S-3 and prior “at-the-market” sales agreements. Rhopressa® will continue to require significant marketing efforts and substantial investment to maintain and increase revenues. RocklatanTM and any future product candidates will require the completion of regulatory review, significant marketing efforts and substantial investment before they can provide us with any revenue.
We expect our research and development expenses to continue to be significant in connection with our ongoing and planned activities. In addition, as we have now launched Rhopressa®, we have incurred and expect to continue to incur increased manufacturing, selling and marketing expenses. As a result, we expect to continue to incur operating losses until our products generate adequate commercial revenue to render Aerie profitable. These losses have had and will continue to have a material adverse effect on our stockholders’ equity, financial position, cash flows and working capital.
We may need to obtain additional financing to fund our operations and, if we are unable to obtain such financing, we may be unable to complete the development and commercialization of Rhopressa®, RocklatanTM or any future product candidates and construction of our new manufacturing plant.
Our operations have consumed substantial amounts of cash since inception. In October 2013, we received net proceeds from our IPO of approximately $68.3 million, after deducting underwriting discounts and commissions and expenses. Since our IPO through December 31, 2018, we have raised additional net proceeds of approximately $122.9 million from the issuance of the 2014 Convertible Notes, which were converted into shares of common stock in July 2018, and approximately $487.7 million through the issuance and sale of common stock under our shelf registration statements on Form S-3 and prior “at-the-market” sales agreements. In July 2018, we entered into an agreement with respect to a senior secured delayed draw term loan facility (the “credit facility”), which will allow us to borrow up to $100 million in one or more borrowings. No amounts were drawn at closing or as of December 31, 2018. See “—Borrowings under the Credit Facility could adversely affect our financial condition and restrict our operating flexibility.”
We may need to obtain additional financing to fund our future operations. Additionally, we may need to obtain additional financing to conduct additional trials for the approval of Rhopressa® in jurisdictionsoutside the United States or of RocklatanTM or any future product candidates, and for completing the development of any additional product candidates or technologies and executing our international expansion strategy. Moreover, our fixed expenses, such as rent and other contractual commitments, are substantial and are expected to increase in the future, and we also expect to incur increased expenses as we expand our employment base.
Our future funding requirements will depend on many factors, including, but not limited to:
the progress, timing, scope and costs of our clinical trials, including the ability to timely enroll patients in our planned and potential future clinical trials;
the time and cost necessary to obtain regulatory approvals that may be required by regulatory authorities;
the time and cost necessary to establish internal manufacturing capabilities or arrangements with third-party manufacturers;
our commercial success with Rhopressa® and our ability to successfully commercialize RocklatanTM and any future product candidates, if approved;
the amount of sales and other revenues from Rhopressa® and RocklatanTM and any future product candidates, if approved, including the selling prices for such potential products and the availability of adequate third-party reimbursement;
selling and marketing costs associated with Rhopressa® and RocklatanTM and any future product candidates, if approved, including the cost and timing of expanding our marketing and sales capabilities;
the terms and timing of any collaborations, licensing or other arrangements that we may establish;
cash requirements of any future acquisitions and/or the development of other product candidates or technologies;
costs of any new business strategies;

the costs of operating as a public company;
the time and cost necessary to respond to technological and market developments; and
the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.
We believe that our existing cash and cash equivalents and expected cash flows will be sufficient to support the expected approval and planned commercialization of RocklatanTM in the United States and to support product commercialization of Rhopressa® through at least the next twelve months. We also intend to use these funds for general corporate purposes and for strategic growth opportunities, including the development and commercialization of Rhokiinsa® and RoclandaTM, if approved, in Europe, the execution of clinical trials in Japan, the expansion of our international operations, the construction of our manufacturing plant in Ireland and the continuation of preclinical activity in support of our product pipeline. In July 2018, we entered into an agreement with respect to a senior secured delayed draw term loan facility, which will allow us to borrow up to $100.0 million in one or more borrowings. See “—Borrowings under the Credit Facility could adversely affect our financial condition and restrict our operating flexibility.” We do not currently intend to draw down on the credit facility but may do so if and as needed.
Until we can generate a sufficient amount of revenue, we are able to finance future cash needs through additional debt financings or other available sources. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay or reduce the scope of or eliminate one or more of our research or development programs or our commercialization or manufacturing efforts. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. In addition, if we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or to grant licenses on terms that may not be favorable to us.
Our forecast of the period of time through which our financial resources will be adequate to support our operating requirements is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on a number of assumptions that may prove to be incorrect and changing circumstances beyond our control may cause us to consume capital more rapidly than we currently anticipate. Our inability to obtain additional funding when we need it could seriously harm our business.
Borrowings under the credit facility could adversely affect our financial condition and restrict our operating flexibility.
In July 2018, we entered into an agreement with respect to a senior secured delayed draw term loan facility, pursuant to which we may borrow up to $100 million in aggregate in one or more borrowings at any time prior to July 23, 2020. The credit facility includes fees upon drawdown of 1.75% of amounts drawn, an 8.625% annual interest rate on drawn amounts, annual fees on undrawn amounts of 1.5% and an exit fee of $1.5 million. No amounts were drawn at closing or as of December 31, 2018. Interest payments, fees, covenants and restrictions under the credit facility could have important consequences, including the following:
impairing our ability to successfully continue to commercialize Rhopressa® or complete the development of RocklatanTM and any future product candidates, which would prevent us from generating a source of revenue and becoming profitable;
limiting our ability to obtain additional financing on satisfactory terms to fund our working capital requirements, capital expenditures, potential acquisitions, debt obligations and other general corporate requirements, and making it more difficult for us to satisfy our obligations with respect to any such additional financing; and
increasing our vulnerability to general economic downturns, competition and industry conditions, which could place us at a competitive disadvantage compared to our competitors with no debt obligations or with debt obligations on more favorable terms.
The occurrence of any one of these events could have an adverse effect on our business, financial condition, operating results or cash flows and ability to satisfy our obligations under the credit facility and any other indebtedness.
Although the agreement governing the credit facility contains restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and any additional indebtedness incurred in compliance with these restrictions could be substantial. If new debt is incurred in addition to debt incurred under the credit

facility, the related risks that we face would be increased.
The terms of the credit facility may restrict our current and future operations, particularly our ability to respond to changes in our business or to take certain actions.
The credit facility contains, and the terms of any future indebtedness of ours would likely contain, a number of restrictive covenants that impose significant operating restrictions, including restrictions on our ability to engage in acts that may be in our best long-term interests. The credit facility includes covenants that, among other things, restrict or otherwise limit our ability to:
incur additional indebtedness and create liens;
make restricted payments;
undergo fundamental changes;
dispose of assets;
make investments; and
enter into transactions with affiliates.
If not cured, as applicable, a breach of any of these provisions could result in a default under the credit facility that would allow our lenders to declare any outstanding debt immediately due and payable. In addition, the credit facility is secured by substantially all of our existing and hereafter created or acquired domestic assets, including our intellectual property, accounts receivable, equipment, general intangibles, inventory and investment property, and all of the proceeds and products of the foregoing. If we are unable to pay any amounts due and payable under the credit facility because we do not have sufficient cash on hand or are unable to obtain alternative financing on acceptable terms, the lenders could initiate a bankruptcy proceeding or proceed against any assets that serve as collateral to secure the credit facility.
These restrictions could limit our ability to obtain future financings, make needed capital expenditures, withstand future downturns in the economy or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of limitations imposed on us by the restrictive covenants under the credit facility.
We may sell additional debt or equity securities at any time, which may result in dilution to our stockholders and impose restrictions on our business.
In order to raise additional funds to support our operations, business strategies and growth, or if we decide based on ongoing forecast updates, new strategic initiatives, market conditions or for other reasons that additional financings are desirable or needed, we may sell additional debt or equity securities, which would result in dilution to all of our stockholders or impose restrictive covenants that adversely impact our business. In September 2016, our automatic shelf registration statement on Form S-3 became effective upon filing with the SEC, pursuant to which we may offer an unlimited amount of common stock from time to time, and, through the date of this report, we have issued and sold approximately 7.4 million shares of common stock pursuant to such shelf registration statement. The incurrence of indebtedness would result in increased fixed payment obligations and could also result in restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected.
Our relatively short operating history may make it difficult for investors to evaluate the success of our business to date and to assess our future viability.
We were incorporated and commenced active operations in the second quarter of 2005. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, developing our product candidates, advancing Rhopressa® and RocklatanTM to FDA approval and the commercial launch of Rhopressa®. We have not yet demonstrated our ability to develop a manufacturing plant or manufacture a widely-sold commercial scale product. Consequently, any predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history.
In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and commercialize our currentother known and potential futureunknown factors. We are in the process of transitioning from a company with a product candidates.
We continually exploredevelopment focus to a company capable of supporting commercial and discuss additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners. We may seek collaboration arrangements with pharmaceutical or biotechnology companies for the development or commercialization of our current and potential future product candidates. We will face, to the extent that we decide to enter into additional collaboration agreements, significant competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time consuming to negotiate, document and implement.manufacturing activities. We may not be successful in completing such transition.

Determining our effortsincome tax rate is complex and subject to establishuncertainty.
The computation of income tax provisions is complex, as it is based on the laws of federal, state, local and implement collaborationsnon-U.S. taxing jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provisions under U.S. GAAP. Our provision for income tax can be materially impacted, for example, by the geographical mix of our profits and losses, changes in our business, such as internal restructuring and acquisitions, changes in tax laws and accounting guidance and other regulatory, legislative or judicial developments, transfer pricing policies, tax audit determinations, changes in our uncertain tax positions, changes in our capital structure and leverage, changes to our transfer pricing practices, tax deductions attributed to equity and other compensation and limitations on such deductions and changes in our need for a valuation allowance for deferred tax assets. In addition, relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates and reduced cash flows than otherwise would be expected. For these reasons, our actual income taxes may be materially different than our provision for income tax.
Our ability to use our net operating loss carryforwards may be limited.
If we experience an “ownership change” for purposes of Section 382 of the Internal Revenue Code of 1986, as amended (Section 382), or similar state provisions, we may be subject to annual limits on our ability to utilize net operating loss carryforwards. An ownership change is, as a general matter, triggered by sales or acquisitions of our stock in excess of 50% on a cumulative basis during a three-year period by persons owning 5% or more of our total equity value.
As of December 31, 2018, we had U.S. federal and state net operating losses (“NOLs”) of approximately $387.7 million and $411.2 million, respectively. If not utilized, federal NOLs that arose before 2018 and state NOLs begin to expire at various dates beginning in 2031 and 2024, respectively. Federal NOLs that arose on or after January 1, 2018 can be carried forward indefinitely to be utilized against future income, but can only be used to offset a maximum of 80% of our federal taxable income in any year. Certain transactions occurred in 2015 and prior years that resulted in ownership changes as defined under Section 382 and similar state provisions, which will limit the future use of certain federal and state NOL carryforwards. Those federal and state NOLs that are not limited are included as deferred tax assets and have been fully offset by a valuation allowance as of December 31, 2018. As of December 31, 2018, we also had foreign NOLs of $44.1 million which are available solely to offset taxable income of our foreign subsidiaries, subject to any applicable limitations under foreign law.
Changes to the United States tax laws could materially impact our financial position and results of operations.
In December 2017, the Tax Act was signed into law. The Tax Act makes extensive changes to the U.S. tax laws and includes provisions that, among other things, reduce the U.S. corporate tax rate, repeal the corporate alternative arrangementsminimum tax (“AMT”) and refund certain existing AMT credits over several years, introduce a capital investment deduction, limit the interest deduction, limit the use of net operating losses to offset future taxable income, limit the deduction for compensation paid to certain executive officers and make extensive changes to the U.S. international tax system, including the taxation of foreign earnings of U.S. multinational corporations. Further, due to the expansion of our international business activities, changes enacted in the Tax Act with respect to the U.S. taxation of such activities may increase our worldwide effective tax rate and adversely affect our financial position and results of operations. The U.S. Treasury Department has released regulations implementing the Tax Act and is expected to release additional regulations and the terms ofU.S. tax laws may be further amended in the future. The Tax Act is complex and far-reaching and we cannot predict with certainty the resulting impact its enactment will have on us.
Our international operations subject us to potentially adverse tax consequences.
We generally conduct our international operations through wholly-owned subsidiaries and report our taxable income, if any, in various jurisdictions worldwide based upon our business operations in those jurisdictions. Our intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such arrangements maya disagreement were to occur, and our position was not sustained, we could be favorablerequired to us. Ifpay additional taxes, interest and when we collaborate with a third party for developmentpenalties, which could result in one-time tax charges, higher effective tax rates and commercialization of a product candidate, we can expect to relinquish some or allreduced cash flows.
In addition, jurisdictions outside the United States could challenge aspects of the control over the future success ofTax Act or implement reactionary legislation or regulations that product candidate to the third party. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations.
Disagreements between parties to a collaboration arrangement regarding research, clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable product candidate and, in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the parties has final decision making authority. Collaborations with pharmaceutical or biotechnology companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration wouldcould adversely affect us financially and could harm our business reputation.and/or negate or minimize any favorable impact that we may derive from the Tax Act in the future.

Risks Related to Our Reliance on Third Parties
We currently depend on third parties to conduct some of the operations of our clinical trials and other portions of our operations, and we may not be able to control their work as effectively as if we performed these functions ourselves.
We rely on third parties, such as CROs, clinical data management organizations, medical institutions and clinical investigators, to oversee and conduct our clinical trials and to perform the related data collection and analysis of our product candidates.analysis. We expect to rely on these third parties to conduct clinical trials of any other potential productsfuture product candidates that we develop. These parties are not our employees and we cannot control the amount or timing of resources that they devote to our program.programs. In addition, any CRO that we retain will be subject to the FDA’s regulatory requirements or similar foreign standards and we do not have control over compliance with these regulations by these providers. Our agreements with third-party service providers are on a trial-by-trial and project-by-project bases. Typically, we may terminate the agreements with notice and are responsible for the third party’s incurred costs. If any of our relationships with our third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. We also rely on other third parties to store and distribute drug supplies for our clinical trials.trials and commercial supply. Any performance failure on the part of our distributors could delay, as applicable, clinical development, or regulatory approval of our product candidates or commercialization of our potential products,Rhopressa®, RocklatanTM or any future product candidates, producing additional losses and depriving us of potential product revenue.
Our reliance on these third parties for clinical development activities reduces our control over these activities but does not relieve us of our responsibilities, and we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan, the protocols for the trial and the FDA’s regulations and international standards, referred to as GCP requirements, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate, and that the rights, integrity and confidentiality of trial participants are protected. Preclinical studies must also be conducted in compliance with the Animal Welfare Act requirements. Managing performance of third-party service providers can be difficult, time consuming and cause delays in our development programs. We currently have a small number of employees, which limits the internal resources we have available to identify and monitor our third-party providers.
Furthermore, these third parties may produce or manufacture competing drugs or may have relationships with other entities, some of which may be our competitors. The use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated.
If these third parties do not successfully carry out their contractual duties or obligations and meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols according to regulatory requirements or for other reasons, our financial results and the commercial prospects for our currentRhopressa® and RocklatanTM and any future product candidates, or our other potential product candidatesif approved, could be harmed, our costs could increase and our ability to obtain regulatory approval (as applicable) and commence product sales could be delayed.

If we fail to manage an effective distribution process in the United States or establish an effective distribution process in jurisdictions outside the United States, our business may be adversely affected.
We do not currently have established the infrastructure necessary for distributing pharmaceutical products to patients. We intend to contract within which third-party logistics wholesalers to warehouse these productsRhopressa® and distribute themit to pharmacies.pharmacies and will need to establish such infrastructures in jurisdictions outside the United States. This distribution network will requirerequires significant coordination with our sales and marketing and finance organizations. Failure to secure contracts with wholesalers could negatively impactorganizations, and the distribution of our potential products, and failure to coordinate financial systems could negatively impact our ability to accurately report product revenue. If we are unable to effectively establish and manage the distribution process, the continued commercialization of Rhopressa® could be disrupted or the commercial launch and sales of our potential productsRhopressa® in jurisdictions outside the United States, in any such case, or of Rocklatan™ or any future product candidates, if approved, will be delayed or severely compromised and our results of operations may be harmed.
Any collaboration arrangement that we may enter into may not be successful, which could adversely affect our ability to develop and commercialize any future product candidates or technologies or to enter new therapeutic areas.
We continually explore and discuss additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners. We may seek collaboration arrangements with pharmaceutical or biotechnology companies or universities for the development or commercialization of our current and potential future product candidates or technologies. For example, in 2017, we entered into a collaborative research, development and licensing agreement with DSM, which was expanded in the third quarter of 2018. We will face, to the extent that we decide to enter into additional collaboration agreements, significant competition in seeking appropriate collaborators. Moreover, collaboration arrangements are often complicated and time consuming to negotiate, document and implement. We may not be successful in our efforts to

establish, implement and maintain collaborations or other alternative arrangements and the terms of such arrangements may not be favorable to us. If and when we collaborate with a third party for development and commercialization of a product candidate and/or technology, we can expect to relinquish some or all of the control over the future success of that product candidate and/or technology to the third party. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations. Accordingly, there can be no assurance that any collaboration or licensing arrangement or similar strategic transaction we enter into will result in the benefits that we anticipate.
Disagreements between parties to a collaboration arrangement regarding research, clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable product candidate or technology and, in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the parties has final decision-making authority. In addition, collaborators may not pursue development and commercialization of our preclinical molecules or product candidates or may elect not to continue or renew development or commercialization programs based on our results, changes in their strategic focus due to the acquisition of competitive products or technologies, availability of funding, or other external factors, such as a business combination that diverts resources or creates competing priorities. Collaborations with pharmaceutical or biotechnology companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration may adversely affect us financially and could harm our business reputation.
Risks Related to Intellectual Property
We may not be able to protect our proprietary technology in the marketplace.
We depend on our ability to protect our proprietary technology. We rely on trade secret, patent, copyright and trademark laws, and confidentiality, licensing and other agreements with employees and third parties, all of which offer only limited protection. Our success depends in large part on our ability and any future licensee’s ability to obtain and maintain patent protection in the United States and other countries with respect to our proprietary technology and products. We believe we will be able to obtain, through prosecution of our current pending patent applications, adequate patent protection for our proprietary drug technology. If we are compelled to spend significant time and money protecting or enforcing our patents, designing around patents held by others or licensing or acquiring, potentially for large fees, patents or other proprietary rights held by others, our business and financial prospects may be harmed. If we are unable to effectively protect the intellectual property that we own, other companies may be able to offer the same or similar products for sale, which could materially adversely affect our competitive business position and harm our business prospects. Our patents may be challenged, narrowed, invalidated, or circumvented, which could limit our ability to stop competitors from marketing the same or similar products or limit the length of term of patent protection that we may have for our products.
The patent positions of pharmaceutical products are often complex and uncertain. The standards of patentability as well as the breadth of claims allowed in pharmaceutical patents in the United States and many jurisdictions outside of the United States is not consistent. For example, in many jurisdictions the support standards for pharmaceutical patents are becoming increasingly strict. Some countries prohibit method of treatment claims in patents. Changes in either the patent laws or interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property or create uncertainty. In addition, publication of information related to our current product candidates and potential products may prevent us from obtaining or enforcing patents relating to thesesuch product candidates and potential products, including without limitation composition-of-matter patents, which are generally believed to offer the strongest patent protection.
Our intellectual property includes issued patents and pending patent applications for compositions of matter, andpharmaceutical formulations, methods of use.use, medical devices and synthetic methods. As of December 31, 2015,2018, we own 1843 patents and have 16seven pending patent applications in the United States and certain foreign jurisdictions for our primary product candidates Rhopressa® and RoclatanRocklatanTM. Patent protection for RoclatanRocklatanTM arises fromincludes the U.S. patents that cover Rhopressa®. The patents cover composition of matter and method of use. We own 4059 patents and have 1155 pending patent applications in the United States and certain foreign jurisdictions relating to our previously discontinued product candidates and other proprietary technology. See “Business—Intellectual Property” included elsewhere in this report for further information about our issued patents and patent applications.
Patents that we own or may license in the future do not necessarily ensure the protection of our intellectual property for a number of reasons, including without limitation the following:
our patents may not be broad or strong enough to prevent competition from other products that are identical or similar to Rhopressa® and RocklatanTM;
our patents may not be broad or strong enough to prevent competition from other products that are identical or similar to our product candidates;
there can be no assurance that the term of a patent can be extended under the provisions of patent term extensionPTE afforded by U.S. law or similar provisions in foreign countries, where available;
our issued patents and patents that we may obtain in the future may not prevent generic entry into the market for our Rhopressa® and RocklatanTM; and Roclatan product candidates;
we do not at this time own or control issued foreign patents outside of Europe that would prevent generic entry into those markets for our product candidates;
we do not currently own or control foreign patents issued outside of Australia, Canada, Europe and Japan that would prevent generic entry into those markets for Rhopressa® and RocklatanTM;
we may be required to disclaim part of the term of one or more patents;
there may be prior art of which we are not aware that may affect the validity or enforceability of a patent claim;

44



there may be prior art of which we are aware, which we do not believe affects the validity or enforceability of a patent claim, but which, nonetheless, ultimately may be found to affect the validity or enforceability of a patent claim;
there may be other patents issued to others that will affect our freedom to operate;
if our patents are challenged, a court of competent jurisdiction could determine that they are invalid or unenforceable;
there might be a significant change in the law that governs patentability, validity and infringement of our patents that adversely affects the scope of our patent rights;
a court of competent jurisdiction could determine that a competitor’s technology or product does not infringe our patents; and
our patents could irretrievably lapse due to failure to pay fees or otherwise comply with regulations or could be subject to compulsory licensing.
If we encounter delays in our development or clinical trials, the period of time during which we could market our potential productsRocklatanTM under patent protection would be reduced.
Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner. Our competitors may seek to market generic versions of any approved productsRhopressa® by submitting ANDAs to the FDA in which our competitors claim that our patents are invalid, unenforceable and/or not infringed. Our competitors may employ similar strategies with respect to RocklatanTM, if approved.
Alternatively, our competitors may seek approval to market their own products similar to or otherwise competitive with our products. In these circumstances, we may need to defend and/or assert our patents, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or other agency withhaving competent jurisdiction may find our patents invalid and/or unenforceable. We may also fail to identify patentable aspects of our research and development before it is too late to obtain patent protection. Even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives.
The issuance of a patent is not conclusive as to its inventorship, scope, ownership, priority, validity or enforceability. In that regard, third parties may challenge our patents in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and potential products. In addition, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized.

A significant portion of our intellectual property portfolio currently comprises pending patent applications that have not yet been issued as granted patents. If our pending patent applications fail to issue our business will be adversely affected.
Our commercial success will depend significantly on maintaining and expanding patent protection for ourRhopressa® and RocklatanTM and any future product candidates, as well as successfully defending our current and future patents against third-party challenges. As of December 31, 2015,2018, we own 58102 patents and have 2762 pending patent applications in the United States and certain foreign jurisdictions relating to Rhopressa®, RocklatanTM and our current and previously discontinued product candidates and other proprietary technology. See “Business—Intellectual Property” included elsewhere in this report for further information about our issued patents and patent applications. Our issued patents include 1843 patents for composition of matter and method of use covering our leadFDA-approved product, candidate, Rhopressa®in the United States and certain foreign jurisdictions. These patents also

cover our other primaryadvanced-stage product candidate RoclatanRocklatanTM to the extent that Rhopressa® forms a part of RoclatanRocklatanTM. The remainder of our portfolio is made up of patents covering previously discontinued product candidates and other proprietary technology and pending patent applications that have not yet been issued by the USPTO, or any other jurisdiction that covercovers Rhopressa®, RocklatanTM or our current and previously discontinued product candidates or other proprietary technology.
There can be no assurance that our pending patent applications will result in issued patents in the United States or foreign jurisdictions in which such applications are pending. Even if patents do issue on any of these applications, there can be no assurance that a third party will not challenge their validity or enforceability, or that we will obtain sufficient claim scope in those patents to prevent a third party from competing successfully with our products.
We may not be able to enforce our intellectual property rights throughout the world.
The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in

45



certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to life sciences. It may be difficult for us to stop the infringement of our patents or the misappropriation of these intellectual property rights in any foreign jurisdictions. For example, some foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit.
Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of intellectual property.
We may infringe the intellectual property rights of others, which may prevent or delay our product development efforts and disrupt the commercialization of or increase the costs of commercializing Rhopressa® or stop us from commercializing or increase the costs of commercializing our products.RocklatanTM or any future product candidates, if approved.
Our commercial success depends significantly on our ability to operate without infringing the patents and other intellectual property rights of third parties. For example, there could be issued patents of which we are not aware that ourRhopressa® or any product candidates or potential products infringe. There also could be patents that we believe we do not infringe, but that we may ultimately be found to infringe.
Moreover, patent applications are in some cases maintained in secrecy until patents are issued. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made and patent applications were filed. Because patents can take many years to issue, there may be currently pending applications of which we are unaware that may later result in issued patents that ourRhopressa®, RocklatanTM or any future product candidates or potential products infringe. For example, pending applications may exist that claim or can be amended to claim subject matter that ourRhopressa®, RocklatanTM or any future product candidates or potential products infringe. Competitors may file continuing patent applications claiming priority to already issued patents in the form of continuation, divisional, or continuation-in-part applications, in order to maintain the pendency of a patent family and attempt to cover ourRhopressa®, RocklatanTM or any future product candidates.
Third parties may assert that we are employing their proprietary technology without authorization and may sue us for patent or other intellectual property infringement. These lawsuits are costly and could adversely affect our results of operations and divert the attention of managerial and scientific personnel. If we are sued for patent infringement, we would need to demonstrate that ourRhopressa®, RocklatanTM or any future product candidates potential products or methods either do not infringe the claims of the relevant patent or that the patent claims asserted are invalid or unenforceable, and we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could be diverted in pursuing these proceedings, which could have a material adverse effect on us. In addition, we may not have sufficient resources to bring these actions to a successful conclusion. If a court holds that any third-party patents are valid, enforceable and cover our products or their use, the holders of any of these patents may be able to block our ability to commercialize our productsRhopressa® or RocklatanTM or any future product candidates, if approved, unless we acquire or obtain a license under the applicable patents or until the patents expire. We may not be able to enter into licensing arrangements or make other arrangements at a reasonable cost or on reasonable terms. Any inability to secure licenses or alternative technology could result in delays in the introduction of our products or lead to prohibition of the manufacture or sale of products by us. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced,

including by court order, to cease commercializing the infringing technology or product. In addition, in any such proceeding or litigation, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our current product candidatesand potential products or force us to cease some of our business operations, which could materially harm our business. Any claims by third parties that we have misappropriated their confidential information or trade secrets could have a similar negative impact on our business. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.
We may be subject to claims that we or our employees have misappropriated the intellectual property, including trade secrets, of a third party, or claiming ownership of what we regard as our own intellectual property.
Many of our employees were previously employed at universities, biotechnology companies or other pharmaceutical companies, including our competitors or potential competitors. Some of these employees, including each membermembers of our senior management, executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that our employees do not use the intellectual property and other proprietary

46



information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed such intellectual property, including trade secrets or other proprietary information. Litigation may be necessary to defend against these claims. We are not aware of any threatened or pending claims related to these matters or concerning the agreements with members of our senior management, but litigation may be necessary in the future to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.
In addition, while we typically require our employees, consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our management and scientific personnel.
We may be unable to adequately prevent disclosure of trade secrets and other proprietary information.
We rely on trade secrets to protect our proprietary know-how and technological advances, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. However, any party with whom we have executed such an agreement may breach that agreement and disclose our proprietary information, including our trade secrets. Accordingly, these agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights. In addition, others may independently discover our trade secrets and proprietary information. Further, the FDA, as part of its Transparency Initiative, a proposal by the FDA to increase disclosure and make data more accessible to the public, is currently considering whether to make additional information publicly available on a routine basis, including information that we may consider to be trade secrets or other proprietary information, and it is not clear at the present time how the FDA’s disclosure policies may change in the future, if at all. Failure to obtain or maintain trade secret protection could enable competitors to use our proprietary information to develop products that compete with our products or cause additional, material adverse effects upon our competitive business position and financial results.
Any lawsuits relating to infringement of intellectual property rights brought by or against us will be costly and time consuming and may adversely impact the price of our common stock.
We may be required to initiate litigation to enforce or defend our intellectual property. These lawsuits can be very time consuming and costly. There is a substantial amount of litigation involving patent and other intellectual property rights in the pharmaceutical industry generally. Such litigation or proceedings could substantially increase our operating expenses and reduce the resources available for development activities or any future sales, marketing or distribution activities.
In any infringement litigation, any award of monetary damages we receive may not be commercially valuable. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. Moreover, there can be no assurance that we will have sufficient financial or other resources to file and pursue such infringement claims, which typically

last for years before they are resolved. Further, any claims we assert against a perceived infringer could provoke these parties to assert counterclaims against us alleging that we have infringed their patents. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.
In addition, our patents and patent applications could face other challenges, such as interference proceedings, opposition proceedings, re-examination proceedings, and other forms of post-grant review. In the United States, for example, post-grant review has recently been expanded. Any of these challenges, if successful, could result in the invalidation of, or in a narrowing of the scope of, any of our patents and patent applications subject to challenge. Any of these challenges, regardless of their success, would likely be time consuming and expensive to defend and resolve and would divert our management and scientific personnel’s time and attention. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the market price of our common stock.

We will need to obtain FDAregulatory approval of any proposed product names, and any failure or delay associated with such approval may adversely affect our business.
We assigned the trade names RhopressaTM® and RoclatanRocklatanTM to our leadnow FDA-approved product candidatesand our advanced-stage product candidate, respectively, in 2014 and 2018, respectively, with the trademark applications for registration for Rhopressa® accepted by the USPTO and the trademark application for registration for RocklatanTMpending from the USPTO. TheseThe trade name Rhopressa® was approved by the FDA. If the EMA approves Rhopressa®, it will be marketed as Rhokiinsa®, for which the USPTO has already accepted our application for trademark registration. RocklatanTM and any other names we intend to use for our current or any future product candidates will require approval from the FDA and applicable non-U.S. regulatory authorities regardless of whether we have secured a formal trademark registration from the USPTO.USPTO or applicable non-U.S. regulatory authorities. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a product name if it believes the name inappropriately implies medical claims or contributes to an overstatement of efficacy. Regulatory authorities outside the United States conduct their own investigations. If the FDA objectsor applicable non-U.S. authorities object to any of our proposed product names, we may be required to adopt an alternative name for ourRhopressa® or Rhokiinsa® outside the United States, RocklatanTM or any future product candidates. In 2018, the EMA approved the name RoclandaTM for RocklatanTM in Europe. A trademark application for RoclandaTM was filed in Europe on October 25, 2018, which remains pending. If, however, we adopt an alternative name, we would lose the benefit of our existing trademark applications for such product or product candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA.FDA or applicable non-U.S. authorities. We may be unable to build a successful brand identity for a new trademark in a timely manner or at all, which would disrupt our commercialization of Rhopressa® outside the United States and limit our ability to commercialize ourRocklatanTM or any future product candidates.
If we do not obtain additional protection under the Hatch-Waxman Amendments and similar foreign legislation extending the terms of our patents and obtaining data exclusivity for ourRhopressa®, RocklatanTM or any future product candidates, our business may be materially harmed.
Depending upon the timing, duration and specifics of FDA regulatory approval for ourRhopressa® and RocklatanTM and any future product candidates, one or more of our U.S. patents may be eligible for limited patent term restorationPTE under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restorationextension term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. Patent term restorations,PTEs, however, cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval by the FDA.
The application for patent term extensionPTE is subject to approval by the USPTO, in conjunction with the FDA. It takes at least six months to obtain approval of the application for PTE. The FDA approved the Rhopressa® NDA on December 18, 2017. On February 8, 2018, we timely filed an application with the USPTO for PTE for our US8394826 patent, term extension.which covers Rhopressa® and RocklatanTM. The petition remains pending. We may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or restorationPTE or the term of any such extension is less than we request, the period during which we will have the right to exclusively market our product will be shortened and our competitors may obtain earlier approval of competing products, and our ability to generate revenues could be materially adversely affected.

Risks Related to Our Business Operations and Industry
We depend upon our key personnel and our ability to attract and retain employees.
Our future growth and success depend on our ability to recruit, retain, manage and motivate our employees. We are highly dependent on our senior management team and our scientific founders, as well as the other principal members of our management and scientific teams. Although we have formal employment agreements with our executive officers, these agreements do not prevent them from terminating their employment with us at any time. The loss of the services of any member of our senior management or scientific team or the inability to hire or retain experienced management personnel could adversely affect our ability to execute our business plan and harm our operating results.

Because of the specialized scientific and managerial nature of our business, we rely heavily on our ability to attract and retain qualified scientific, technical and managerial personnel. In particular, the loss of Vicente Anido, Jr., our Chairman of the Board of Directors and Chief Executive Officer, Thomas A. Mitro, our President and Chief Operating Officer, Richard J. Rubino, our Chief Financial Officer, or Casey C. Kopczynski, our Chief Scientific Officer, John LaRocca, Esq., our General Counsel, or Kathleen McGinley, our Vice President of Human Resources and Corporate Services, could be detrimental to us if we cannot recruit suitable replacements in a timely manner. We do not currently carry “key person” insurance on the lives of members of executive management. The competition for qualified personnel in the pharmaceutical field is intense. Due to this intense competition, we may be unable to continue to attract and retain qualified personnel necessary for the development of our business or to recruit suitable replacement personnel. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.
We will need to significantly increasehave increased the size of our organization, and we may experience difficulties in managing our growth.
We are currently a small company with 70have increased the size of our organization. We have 353 full-time employees as of December 31, 2015. In order2018 compared to commercialize160 full-time employees as of December 31, 2017. We are currently expanding our potential products,employment base as we will need to substantially increase our operations. We plan to continue to buildexpand internationally, including for the future operation of our compliance, financial

manufacturing plant in Ireland, and operating infrastructurefor continued research activities to ensure the maintenance of a well-managed company.further expand our pipeline. We expect to expand our employment base to approximately 300400 full-time employees when we are in the full commercial stages of our current potential products’ life cycle.and manufacturing stage for Rhopressa® and RocklatanTM, if approved, in the United States.
Future growth will imposeGrowth imposes significant added responsibilities on members of management, including the need to identify, recruit, maintain and integrate additionalnew employees. Our management, personnel and systems currently in place may not be adequate to support our future growth. Our future financial performance and our ability to commercialize our potential productsRhopressa® and RocklatanTM and any future product candidates, if approved, and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to:
manage our research programs, clinical trials and the regulatory process effectively;
manage the development and eventual operation of our manufacturing plant and the manufacturing of Rhopressa®, RocklatanTM and any future product candidates and potential products for clinical and commercial use;
integrate current and additional management, administrative, financial, manufacturing and sales and marketing personnel;
develop a marketing and sales infrastructure;
hire new personnel necessary to effectively commercialize our product candidates;
hire additional personnel necessary to effectively commercialize and manufacture Rhopressa® and RocklatanTM and any future product candidates, if approved;
continue to develop and maintain our administrative, accounting and management information systems and controls; and
hire and train additional qualified personnel.
Product candidates that we may acquire or develop in the future may be intended for patient populations that are large. In order to continue development and marketing of these product candidates, if approved, we would need to significantly expand our operations. Our staff, financial resources, systems, procedures or controls may be inadequate to support our operations and our management may be unable to manage successfully future market opportunities or our relationships with customers and other third parties.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading, which could significantly harm our business.
We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators, provide accurate information to the FDA and non-U.S. regulators, comply with healthcare fraud and abuse laws and regulations in the United States and abroad, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We adopted a code of conduct, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.
Our business is affectedmay be negatively impacted by macroeconomic conditions.
Various macroeconomic factors could adversely affect our business and the results of our operations and financial condition, including changes in inflation, interest rates and foreign currency exchange rates and overall economic conditions and uncertainties, including those resulting from the current and future conditions in the global financial markets. For instance, if and when our product candidates are approved, if inflation or other factors were to significantly increase our business costs, it may not be feasible to pass through price increases to patients. Interest rates, the liquidity of the credit markets and the volatility of the capital markets could also affect the value of our investments and our ability to liquidate our investments in order to fund our operations.
Interest rates and the ability to access credit markets could also adversely affect the ability of patients, payorspayers and distributors to purchase, pay for and effectively distribute our potential products.Rhopressa® or RocklatanTM or any future product candidates, if approved. Similarly, these macroeconomic factors could affect the ability of our potential future contract manufacturers, sole-source or single-source suppliers, collaboration partners or licensees

49


to remain in business or otherwise develop, manufacture or supply product. Failure by any of them to remain in business could affect our ability to manufacture potential products.Rhopressa® or RocklatanTM or any future product candidates, if approved, or develop additional product candidates or technologies.
A significant portion of our revenue currently comes from a limited number of distributors, and any decrease in revenue from these distributors could harm our business.
A significant portion of our revenue comes from a limited number of distributors. In the year ended December 31, 2018, three distributors represented approximately 33.9%, 33.3% and 29.7% of total revenues. We further expect that a significant portion of our revenue will continue to depend on sales to a limited number of distributors in the foreseeable future. We do not have long-term commitments from our distributors to carry our products, and any of our distributors may from quarter to quarter comprise a significant concentration of our revenues. Our dependence on a few distributors could expose us to the risk of substantial losses if any single large distributor stops purchasing our products, purchases a lower quantity of our products or goes out of business and we cannot find substitute distributors on equivalent terms without delays, if at all. While we may be able to shift our business to one of our other existing distributors or to a new distributor, there may be disruption in the interim. In addition, any reduction in the prices we receive for our products could adversely impact our revenues and financial condition. If we lose our relationship with any of our significant distributors, we could experience delays in the distribution of our products and could also experience declines in our revenues which in turn could materially adversely affect our business, results of operations or financial condition.
If we engage in acquisitions or licenses in the future, we will incur a variety of costs and we may never realize the anticipated benefits of such acquisitions or licenses.
We may attempt to acquire or license businesses, technologies, services, products or product candidates in the future that we believe are a strategic fit with our business. For example, in October 2017, we acquired the rights to use PRINT® technology and certain other assets from Envisia Therapeutics Inc. Further, in August 2018 we entered into an Amended and Restated Collaborative Research, Development, and License Agreement with DSM, which provides for (i) a worldwide exclusive license for all ophthalmic indications to DSM’s polyesteramide polymer technology, (ii) continuation of the collaborative research initiatives through the end of 2020, including the transfer of DSM’s formulation technology to Aerie during that time and (iii) access to a preclinical latanoprost implant. We have no present agreement regarding any material acquisitions or licenses.acquisitions. However, if we

do undertake any acquisitions or additional licenses, the process of integrating an acquired or licensed business, technology, service, product or product candidate into our business may result in unforeseen operating difficulties and expenditures, including diversion of resources and management’s attention from our core business. In addition, we may fail to retain key executives and employees of the companies we acquire, which may reduce the value of the acquisition or give rise to additional integration costs. Future acquisitions or licenses could result in additional issuances of equity securities that would dilute the ownership of existing stockholders. Future acquisitions or licenses could also result in the incurrence of debt, actual or contingent liabilities or the amortization of expenses related to intangible assets, any of which could adversely affect our operating results.
We have limited experience identifying, negotiating and implementing acquisitions or licenses of additional businesses, technologies, services, products or product candidates, which is a lengthy and complex process. The market for acquiring or licensing businesses, technologies, services, products or product candidates is intensely competitive, and other companies, including some with substantially greater financial, marketing and sales resources, may also pursue strategies to acquire or license businesses, technologies, products or product candidates that we may consider attractive. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us.
We have limited resources to identify and execute the acquisition or licensing of additional businesses, technologies, services, products, or product candidates and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. We may not be able to acquire or license the rights to additional businesses, technologies, services, products or product candidates on terms that we find acceptable, or at all. In particular, any product candidate that we acquire or license may require additional development efforts prior to commercial sale, including extensive clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities.
Business interruptions could delay us in the processdevelopment of developing our potential products and our manufacturing activities, and could disrupt our potential sales.
Our principal executive officesoffice and research facility is located in Durham, North Carolina, our regulatory, commercial support and other administrative activities are located in Irvine, California, and our clinical and finance operations are located in Bedminster, New JerseyJersey. We also lease space for a manufacturing plant in Athlone, Ireland and our researchsmall offices in Malta, Ireland, the United Kingdom and development facility is located in Durham, North Carolina.Japan. We are vulnerable to natural disasters, such as severe storms, and other adverse events that could disrupt our operations. We do not carry limited insurance for natural disasters and other adverse events and we may not carry sufficient business interruption insurance to compensate us for losses that may occur. Any losses or damages we incur could have a material adverse effect on our business operations.
Our business and operations would suffer in the event of system failures.failures, cyber-attacks or other security breaches.
Despite the implementation of security measures, our internal computer systems, and those of our CROs, sales force, collaborators and other third parties on which we rely, are vulnerable to damage from computer viruses, unauthorized access, malware, ransomware, natural disasters, terrorism, war, and telecommunication and electrical failures.failures, cyber-attacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusions, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Computer hackers may attempt to penetrate our computer systems and, if successful, misappropriate our proprietary and confidential information including e-mails and other electronic communications. In addition, an employee, supplier, collaboration partner or other third party with whom we do business may attempt to obtain such information and may purposefully or inadvertently cause a breach involving such information. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs.programs, manufacturing activities and/or commercialization efforts, damage our reputation, provide competitors with valuable information and subject us to additional liabilities, including criminal penalties and civil sanctions. We have not been subject to cyber-attacks or other cyber incidents to date which, individually or in the aggregate, have been material to our business, but the actions we take to prevent or detect the risk of cyber incidents and protect our information technology networks and infrastructure may be insufficient to prevent or detect a major cyber-attack or other cyber incident in the future.
In addition, there is a risk created by our lack of redundancy across our systems and if any of these events were to occur, this could result in a loss of materials that would be difficult to replace, such as proprietary information including intellectual property and business information and/or customer, supplier, employee, business partner and, in certain instances, patient

personally identifiable information. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties to manufacture Rhopressa®, and similar events relating to their systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the commercialization of Rhopressa® and the further development or commercialization of ourRocklatanTM and any future product candidates could be delayed.
Our actual or perceived failure to comply with U.S. federal, state, and foreign governmental regulations and other legal obligations related to privacy, data protection and information security could harm our reputation and business.
In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information, data about our clinical participants, suppliers and business partners and personally identifiable information. The secure storage, maintenance, and transmission of and access to this information is important to our operations and reputation. Any access, disclosure or other loss of information could result in legal claims or proceedings, disruption of our operations and damage to our reputation, all of which could materially adversely affect our business. In addition, we are subject to various U.S. federal and state and international privacy and security regulations. For example, the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common healthcare transactions, as well as standards relating to the privacy and security of individually identifiable health information, which require the adoption of administrative, physical and technical safeguards to protect such information. In addition, many U.S. states have enacted comparable laws addressing the privacy and security of health information, some of which are more stringent than HIPAA. With our increasing international presence, we are also subject to the laws of jurisdictions outside the United States. Privacy and data protection laws may be interpreted and applied differently from country to country and may create inconsistent or conflicting requirements, which could increase the costs incurred by us in complying with such laws.
The EU member states, Switzerland, Japan and other countries have established, or are in the process of establishing, legal frameworks for privacy and data security that impose significant compliance obligations with which our customers, our vendors or we must comply. For example, the GDPR, which became effective on May 25, 2018, imposes strict requirements on data controllers and processors of personal data. The GDPR is wide-ranging in scope and imposes numerous requirements, including requirements relating to processing sensitive data (including health, biometric and genetic information), obtaining consent of the individuals to whom the personal data relates, providing information to individuals regarding data processing activities, implementing safeguards to protect the security and confidentiality of personal data, providing notification of data breaches and taking certain measures when engaging third-party processors. In addition, the GDPR grants individuals an express right to seek legal remedies in the event the individual believes his or her rights have been violated. Further, the GDPR imposes strict rules on the transfer of personal data out of the EU, including to the United States and other regions.
The GDPR introduced new fines and penalties for a breach of requirements, which may result in significant fines of up to 4% of annual global revenues, or €20.0 million, whichever is greater. Compliance with the GDPR will be a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, in particular as regards data processing in the context of clinical trials. As a result of the implementation of the GDPR, we were required to put in place additional mechanisms to ensure compliance with the new data protection rules, although there is a risk that the measures will not be implemented correctly or that individuals within our business will not be fully compliant with the new procedures. If there are any breaches of these measures, we could face significant administrative and monetary sanctions as well as reputational damage, which may have a material adverse effect on our business.
Our disclosure controls and procedures and our systems to implement such disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
As a public company, we are subject to the periodic reporting requirements of the Exchange Act. Our disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within

50



the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

We are in the process of implementing a new global enterprise resource planning (“ERP”) system. This ERP system will replace many of our existing financial systems. Such an implementation is a significant undertaking, both financially and from a management and personnel perspective. Any disruptions, delays or deficiencies in the design and implementation of our new ERP system could adversely affect our ability to process financial transactions, maintain effective disclosure or internal controls and procedures, fulfill contractual obligations or could otherwise materially adversely affect our business.
If product liability lawsuits are successfully brought against us, our insurance may be inadequate and we may incur substantial liability.
We face an inherent risk of product liability claims as a result of the clinical testing of our product candidates. We face an additional risk from our commercial sales of Rhopressa® and will face an even greater risk ifwhen we commercially sell our potential productsRocklatanTM or any otherfuture product candidate that we develop.candidates, if approved. We maintain primary product liability insurance and excess product liability insurance that cover our clinical trials, and we have and plan to maintain insurance against product liability lawsuits for commercial sale of our potential products.Rhopressa® and RocklatanTM and any future product candidates, if approved. Historically, the potential liability associated with product liability lawsuits for pharmaceutical products has been unpredictable. Although we believe that our current insurance is a reasonable estimate of our potential liability and represents a commercially reasonable balancing of the level of coverage as compared to the cost of the insurance, we may be subject to claims in connection with our clinical trials and, in the future, commercial use of our potential products,Rhopressa® or RocklatanTM or any future product candidates, if approved, for which our insurance coverage may not be adequate, and the cost of any product liability litigation or other proceeding, even if resolved in our favor, could be substantial.
For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated adverse effects. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of ourRhopressa® or RocklatanTM or any future product candidates.candidates, if approved. Regardless of the merits or eventual outcome, liability claims may result in:
reduced resources of our management to pursue our business strategy;
decreased demand for our product candidates or products that we may develop;
decreased demand for Rhopressa® or RocklatanTM or any future product candidates, if approved;
injury to our reputation and significant negative media attention;
withdrawal of clinical trial participants;
termination of clinical trial sites or entire trial programs;
initiation of investigations by regulators;
product recalls, withdrawals or labeling, marketing or promotional restrictions;
significant costs to defend resulting litigation;
diversion of management and scientific resources from our business operations;
substantial monetary awards to trial participants or patients;
loss of revenue; and
the inability to commercialize any products that we may develop.
We will need to increaseincreased our insurance coverage if and when we begin selling our product candidates if and when they receive marketingRhopressa® received FDA approval. However, the product liability insurance we will need to maintain in connection with the continued commercial sales of Rhopressa®, and will need to obtain in connection with the commercial sales of ourRocklatanTM and any future product candidates if and when they receive regulatory approval, may be unavailable in meaningfuladequate amounts or at a reasonable cost. In addition, insurance coverage is becoming increasingly expensive. If we are unable to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims, it could preventinhibit the continued commercial production and sale of Rhopressa® or inhibit the development and commercial production and sale of ourRocklatanTM or any future product candidates if and when they obtain regulatory approval, which could materially adversely affect our business, financial condition, results of operations, cash flows and prospects.

51


Additionally, we do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability, employment practices liability, property, auto, workers’ compensation, products liability and directors’ and officers’ insurance. We do not know, however, if we will be able to maintain insurance with adequate

levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would materially adversely affect our financial position, cash flows and results of operations.
Risks Related to Ownership of Our Common Stock
The market price of our common stock has been, and may continue to be, highly volatile.
Our stock price has been volatile and is likely to continue to be volatile. The following factors, in addition to other factors described in this “Risk Factors” section, may have a significant impact on the market price of our common stock:
the resultssuccess of our testing and clinical trials, including the resultscommercial launch of our Phase 3 registration trials for RhopressaTM ® in the United States, including associated sales volumes, revenues and Roclatanprofitability;
the anticipated approval of RocklatanTM; by the FDA, and the success of the commercial launch in the United States, if approved;
overall company profitability and ability to generate positive cash flows, and elimination of the additional costs associated with financing overhang;
our ability to maintain adequate product supply to meet demand;
our ability to obtain regulatory approval in jurisdictions outside the United States;
the results of our testing and clinical trials;
announcements of regulatory approval or a complete response letter, or specific label indications or patient populations for its use, or changes or delays in the regulatory review process;
announcements of therapeutic innovations or new products by us or our competitors;
adverse actions taken by regulatory agencies with respect to our clinical trials, manufacturing supply chain or sales and marketing activities;
any adverse changes to our relationships with manufacturers, suppliers, licensees or collaboration partners;
the results of our efforts to develop, acquire or license additional product candidates;
variations in the level of expenses related to our existing product candidates or preclinical and clinical development programs;technologies;
variations in the level of expenses related to Rhopressa®, RocklatanTM or preclinical and clinical development programs;
any intellectual property infringement actions in which we may become involved;
announcements concerning our competitors or the pharmaceutical industry in general;
achievement ofactual versus expected product sales and profitability;
manufacture, supply or distribution shortages;
actual or anticipated fluctuations in our quarterly or annual operating results;
changes in financial estimates or recommendations by securities analysts;
trading volume of our common stock;
sales of our common stock by us, our executive officers and directors or our stockholders in the future;
general economic and market conditions and overall fluctuations in the capital markets;
changes in accounting principles; and
the loss of any of our key scientific or management personnel.
In addition, the stock market, in general, and small pharmaceutical and biotechnology companies have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. Further, the currentany decline in the financial markets and related factors beyond our control may cause our stock price to decline rapidly and unexpectedly.
We have been named a defendant in a purported securities class action lawsuit. This, and any additional
Any securities litigation could result in substantial damages and may divert management’s time and attention from our business.
On April 23, 2015, we announced that Rocket 1 did not meet its primary efficacy endpoint. A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against us and certain of our officers and directors in the United States District Court for the District of New Jersey on April 29, 2015. An amended complaint was filed on September 28, 2015, on behalf of a purported class of persons and entities who purchased or otherwise acquired our publicly traded securities between June 25, 2014 and April 23, 2015. The amended complaint asserts claims under

52


the Exchange Act and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of Rocket 1 and RhopressaTM.
We believe that we have meritorious defenses and intend to defend the lawsuit vigorously. The outcome of this lawsuit is necessarily uncertain, we could be forced to expend significant resources in the defense of this suit and we may not prevail. We are not currently able to estimate the possible cost to us from this matter, as this lawsuit is currently at an early stage and we cannot be certain how long it may take to resolve this matter or the possible amount of any damages that we may be required to pay. It is possible that we could, in the future, incur judgments or enter into settlements of claims for monetary damages. A decision adverse to our interests on this action could result in the payment of substantial damages, or possibly fines, and could have a material adverse effect on our business, financial condition and results of operations. In addition, the uncertainty of the currently pending litigation could lead to volatility in our stock price.
which has now concluded. If our stock price experiences volatility, we may be the subject of additional securities litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could adversely impact our business. Monitoring and defending against legal actions is time-consuming for our management and detracts from our ability to fully focus on our business activities. Any adverse determination in litigation could also subject us to significant liabilities.
Certain of our existing stockholders, executive officers and directors own a significant percentage of our common stock and may be able to influence or control matters submitted to our stockholders for approval.
Our officers and directors, and stockholders who own more than 5% of our outstanding common stock, beneficially own approximately 66.1%52.7% of our common stock as of December 31, 2015.2018. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with ownership concentration. Some or all of our stockholders may be able to influence or determine matters requiring stockholder approval. The interests of these stockholders may not always coincide with our interests or the interests of other stockholders.
This may also prevent or discourage unsolicited acquisition proposals or offers for our common stock that other stockholders may feel are in their best interest, and certain of our existing stockholders may act in a manner that advances their best interests and not necessarily those of other stockholders, including seeking a premium value for their common stock, and might affect the prevailing market price for our common stock.
Additionally, under certain circumstances, our amended and restated certificate of incorporation renounces any interest or expectancy that we have in, or in being offered an opportunity to participate in, corporate opportunities that are presented to certain of our existing stockholdersentities or their affiliates and certain other related parties (whether or not any such person is our director). These provisions will apply even if the opportunity is one that we might reasonably have pursued or had the ability or desire to pursue if granted the opportunity to do so.
Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.
Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.
If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they adversely change their recommendations or publish negative reports regarding our business or our stock, our stock price and trading volume could decline.
The trading market for our common stock may be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market or our competitors. We do not have any control over these analysts and we cannot provide any assurance that analysts will continue to cover us or provide favorable coverage. If any of the analysts who may cover us adversely change their recommendation regarding our stock, or provide more favorable relative recommendations about our competitors, our stock price could decline. If any analyst who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

Because we do not intend to declare cash dividends on our shares of common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.

53


We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends in the foreseeable future. In addition, the terms of the 2014 Convertible Notescredit facility and any future debt agreements may preclude us from paying dividends. As a result, we expect that only appreciation of the price of our common stock, if any, will provide a return to investors for the foreseeable future.

The requirements associated with being a public company require significant company resources and management attention.
We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002, as amended or the Sarbanes-Oxley Act,(the “Sarbanes-Oxley Act”), the listing requirements of the securities exchange on which our common stock is traded, and other applicable securities rules and regulations. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition and maintain effective disclosure controls and procedures and internal control over financial reporting. In addition, subsequent rules implemented by the SEC and NASDAQ may also impose various additional requirements on public companies. As a result, we have incurred, and we will continue to incur, additional legal, accounting and other expenses that we did not incur as a nonpublic company, particularly after we are no longer an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Further, the need to establish the corporate infrastructure demanded of a public company may divert management’s attention from implementing our growth strategy. We have made, and will continue to make, changes to our corporate governance standards, disclosure controls and financial reporting and accounting systems to continue to meet our reporting obligations. However, the measures we take may not be sufficient to satisfy our obligations as a public company, which could subject us to delisting of our common stock, fines, sanctions and other regulatory action and potentially civil litigation.
The JOBS Act allows usWe are subject to postpone the date by which we must comply with some of the laws and regulations intended to protect investors and to reduce the amount of information we provide in our reports filed with the SEC, which could undermine investor confidence in our company and adversely affect the market price of our common stock.
For so long as we remain an “emerging growth company” as defined in the JOBS Act, we may take advantage of certain exemptions from various requirements that are applicable to public companies that are not “emerging growth companies” including:
the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring(“Section 404”), which requires that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting;
reporting, among other additional requirements. Compliance with Section 404 is costly and time consuming for management and could result in the “say on pay” provisions (requiring a non-binding stockholder vote to approve compensationdetection of certain executive officers) and the “say on golden parachute” provisions (requiring a non-binding stockholder vote to approve golden parachute arrangements for certain executive officers in connection with mergers and certain other business combinations) of the Dodd-Frank Act and some of the disclosure requirements of the Dodd-Frank Act relating to compensation of its chief executive officer; and
the requirement to provide detailed compensation discussion and analysis in proxy statements and reports filed under the Exchange Act, and instead provide a reduced level of disclosure concerning executive compensation.
We may take advantage of these exemptions until we are no longer an “emerging growth company.” We would cease to be an “emerging growth company” upon the earliest of: (i) December 31, 2018; (ii) the last day of the first fiscal year in which our annual gross revenues are $1 billion or more; (iii) the date on whichinternal control deficiencies. Moreover, if we have during the previous three-year period, issued more than $1 billiona material weakness in non-convertible debt securities;our internal controls over financial reporting, we may not detect errors on a timely basis, and our financial statements may be materially misstated. We or (iv) as of the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million as of the end of the second quarter of that fiscal year.
We currently take advantage of some, but not all, of the reduced regulatory and reporting requirements that are available to us so long as we qualify as an “emerging growth company.” For example, we have irrevocably elected under Section 107 of the JOBS Act not to take advantage of the extension of time to comply with new or revised financial accounting standards available under Section 102(b) of the JOBS Act. Our independent registered public accounting firm ismay not requiredbe able to provideconclude on an attestation report on the effectiveness of ourongoing basis that we have effective internal controlcontrols over financial reporting, so long as we qualify as an “emerging growth company,” which may increase the risk that weaknesses or deficienciescould harm our operating results, cause investors to lose confidence in our internal control over financial reporting go undetected. Likewise, so long as we qualify as an “emerging growth company,” we may elect not to provide investors with certain information, including certainreported financial information and certain information regarding compensationcause the trading price of our executive officers,common stock to fall. Any failure to file accurate and timely quarterly and annual reports that we would otherwise have beenare required to provide in filings we makefile with the SEC which may make it more difficult for investors and securities analysts to evaluateunder the Exchange Act could result in sanctions, lawsuits, delisting of our company. We cannot predict if investors will findshares from The NASDAQ Global Market or other adverse consequences that would materially harm our common

stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile and may decline.business.
Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our current management.
Provisions in our restated certificate of incorporation and our bylaws, as well as provisions of the Delaware General Corporation Law or DGCL,(“DGCL”), could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions include:
establishing a classified board of directors such that not all members of the board are elected at one time;
allowing the authorized number of our directors to be changed only by resolution of our board of directors;
limiting the removal of directors by the stockholders;
authorizing the issuance of “blank check” preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval;
prohibiting stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders;
eliminating the ability of stockholders to call a special meeting of stockholders;
establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings; and
requiring the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal our bylaws.
These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, we are subject to Section 203 of the DGCL, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by our board of directors. This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by or beneficial to our stockholders.

ITEM 3. LEGAL PROCEEDINGS
We may periodically become subject to legal proceedings and claims arising in connection with our business. Except as set forth below, weWe are not a party to any known litigation, are not aware of any material unasserted claims and do not have contingency reserves established for any litigation liabilities.
A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against us and certain of our officers and directors in the United States District Court for the District of New Jersey on April 29, 2015. An amended complaint was filed on September 28, 2015 on behalf of a purported class of persons and entities

55



who purchased or otherwise acquired our publicly traded securities between June 25, 2014 and April 23, 2015. The amended complaint asserts claims under the Exchange Act and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of Rocket 1 and RhopressaTM.
We believe that the claims in the asserted action are without merit and intend to defend the lawsuit vigorously, and we expect to incur costs associated with defending the action. In addition, we have various insurance policies related to the risks associated with our business, including directors’ and officers’ liability insurance policies. However, there is no assurance that we will be successful in our defense of the action, and there is no assurance that our insurance coverage, which contains a self-insured retention, will be sufficient or that our insurance carriers will cover all claims or litigation costs. At this time, we cannot accurately predict the ultimate outcome of this matter. Due to the inherent uncertainties of litigation, we cannot reasonably predict the timing or outcomes, or estimate the amount of loss, or range of loss, if any, or their effect, if any, on our financial statements.

Stock Performance Graph
The following graph illustrates a comparison of the five-year cumulative total cumulative stockholder return on our common stock since October 25,December 31, 2013 which is the date our common stock first began trading on the NASDAQ Global Market, to two indices: the NASDAQ Composite Index and the NASDAQ Biotechnology Index. The graph assumes an initial investment of $100 on October 25,December 31, 2013, in our common stock and in the stocks comprising each index. It also assumes reinvestment of dividends, if any. Historical stockholder return shown is not necessarily indicative of future performance, and we do not make or endorse any predictions as to future stockholder returns.

*This performance graph shall not be deemed “soliciting material” or be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities under that Section, and shall not be deemed to be incorporated by reference into any of our filings under the Securities Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.
Dividend Policy
We have not declared or paid any cash dividends on our capital stock in the last two fiscal years. We currently anticipate that we will retain future earnings, if any, for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends in the foreseeable future. In addition, the terms of our current and any future debt agreements may preclude us from paying dividends. As a result, we anticipate that only appreciation of the price of our common stock, if any, will provide a return to investors for at least the foreseeable future.
Purchase of Equity Securities
We did not purchase any of our equity securities during the period covered by this report.
Recent Sales of Unregistered Securities
None.

Use of Proceeds from Registered Securities
On November 3, 2014, we filed a shelf registration statement on Form S-3 (Registration No. 333-199821), which was declared effective by the SEC on November 10, 2014. The shelf registration statement permits: (i) the offering, issuance and sale by us

58



of up to a maximum aggregate offering price of $150.0 million of our common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that was offered, issued and sold by us under the “at-the-market” sales agreement was included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement. As of December 31, 2015, we had no availability to issue shares under this “at-the-market” sales agreement.
On November 6, 2015, we filed a prospectus supplement to the base prospectus dated November 10, 2014. The prospectus supplement permits the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under separate “at-the-market” sales agreements with RBC Capital Markets, LLC and Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by us under these “at-the-market” sales agreements is included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement. As of December 31, 2015, $48.1 million remained available for issuance under these “at-the-market” sales agreements.
For the year ended December 31, 2015, we issued and sold 1,754,556 shares of our common stock under the “at-the-market” sales agreements and received net proceeds of $50.5 million, after deducting commissions at a rate of up to 3% of the gross sales price per share sold and other fees and expenses. There were no sales of securities registered pursuant to the shelf registration statement for the year ended December 31, 2014.
We currently hold the net proceeds from the “at-the-market” sales as cash deposits and in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities. There has been no material change in our planned use of the net proceeds as described in our shelf registration statement filed on November 3, 2014.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following management’s discussion and analysis should be read in conjunction with our audited financial statements and related notes that appear elsewhere in this Annual Report on Form 10-K. This management’s discussion and analysis contains forward-looking statements that involve risks and uncertainties. Please see “Special Note Regarding Forward-Looking Statements” for additional factors relating to such statements, and see “Risk Factors” in Part I, Item 1A of this report for a discussion of certain risk factors applicable to our business, financial condition and results of operations. Past operating results are not necessarily indicative of operating results in any future periods.
Overview
We are a clinical-stagean ophthalmic pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye. Our two advanced stagestrategy is to successfully commercialize our FDA-approved product, Rhopressa®, in the United States and advance our product candidate, RocklatanTM, to regulatory approval. We have a commercial team that includes approximately 100 sales representatives targeting approximately 14,000 high prescribing eye-care professionals throughout the United States. This sales force is responsible for sales of Rhopressa®, and will also be responsible for sales of RocklatanTM, if approved.
We seek to enhance our longer-term commercial potential by identifying and advancing additional product candidates arethrough our internal discovery efforts, our entry into potential research collaborations or in-licensing arrangements or our acquisition of additional ophthalmic products or technologies or product candidates that complement our current product portfolio, such as our collaboration with DSM, whereby we have access to their bio-erodible polymer technology, and our acquisition of assets from Envisia, designed to lower intraocular pressure, or IOP,advance our progress in patients with open-angle glaucoma and ocular hypertension. Bothdeveloping potential future sustained-release product candidates to treat retinal diseases, as discussed below.
Our strategy also includes developing our business outside of the United States, including obtaining regulatory approval in Europe and Japan on our own for Rhopressa® and RocklatanTM. If we obtain regulatory approval, we currently expect to commercialize Rhokiinsa® and RoclandaTM in Europe on our own, and likely partner for commercialization of their equivalents in Japan. To optimize the commercial opportunity, we expect to launch RoclandaTM before Rhokiinsa® in Europe, if approved, as the European market is oriented more toward fixed-dose combination products. We are continuing to expand our presence in Europe and are actively participating in European ophthalmology conferences and forums. We now have over 60 employees in Europe that manage the build-out and operation of our manufacturing plant in Ireland, discussed below, as well our Phase 3 clinical trial for RoclandaTM, which is ongoing in several European countries. We are also building our clinical, medical affairs and commercial teams in Europe. In Japan, we announced the opening of our office in Tokyo and the hiring of key leadership positions to help execute our strategy in that market.
In January 2017, we commenced establishment of our own manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, which is expected to produce commercial supplies of Rhopressa® and, if approved, RocklatanTM,Rhokiinsa® and RoclandaTM. Commercial supply from the plant is expected to be available in early 2020. Our current contract manufacturer produces commercial supply of Rhopressa® and started to manufacture RocklatanTM in 2018 in anticipation of potential FDA approval and commercial launch in 2019. We are also in the process of adding an additional API contract manufacturer and an additional Rhopressa® drug product contract manufacturer, both of which are expected to supply commercial materials in the first half of 2019. We expect to continue to use product sourced from our contract manufacturers when the Ireland plant is operational.
We own the worldwide rights to all indications for Rhopressa® and RocklatanTM. We have patent protection for Rhopressa® and RocklatanTM in the United States through early 2034 and internationally, through dates ranging from 2030 to 2037. Our intellectual property portfolio contains patents and pending patent applications related to composition of matter, pharmaceutical compositions, methods of use, and synthetic methods. Furthermore, we have patent protection for AR-13503 in the United States and internationally, which extends to 2030. We have also filed for patent protection for AR-1105 in the United States and internationally.
Product and Product Candidate Overview
Rhopressa®, our FDA-approved product, has demonstrated that it reduces IOP through ROCK inhibition, its MOA, by which Rhopressa® increases the outflow of aqueous humor through the TM, which accounts for approximately 80% of fluid drainage from the healthy eye. Our advanced-stage product candidate is once-daily RocklatanTM, a fixed-dose combination of

Rhopressa® and latanoprost, reduces IOP through the same MOA as Rhopressa® and through a second MOA, utilizing the ability of latanoprost to increase the outflow of aqueous humor through the uveoscleral pathway, the eye’s secondary drain. Both are taken once-daily in the evening and have shown in preclinical and clinical trials to be effective in loweringreducing IOP, with novel mechanismsa favorable safety profile.
Rhopressa®
Rhopressa® is a once-daily eye drop designed to reduce elevated IOP in patients with open-angle glaucoma or ocular hypertension. The active ingredient in Rhopressa®, netarsudil, is an Aerie-owned ROCK inhibitor. We believe that Rhopressa® represents the first of action,a new drug class for reducing IOP in patients with glaucoma in over 20 years. Initial indications point to healthcare professionals prescribing Rhopressa® as a concomitant therapy to prostaglandins or MOAs,non-PGA medications when additional IOP reduction is desired. We believe Rhopressa® is primarily competing with other non-PGA products, due to its targeting of the diseased TM, its demonstrated ability to reduce IOP at consistent levels across tested baselines, its preferred once-daily dosing relative to other currently marketed non-PGA products and its safety profile. Adjunctive therapies currently represent nearly one-half of the glaucoma prescription market in the United States, according to IQVIA. We believe that Rhopressa® may also become a preferred therapy where PGAs are contraindicated, for patients who do not respond to PGAs and for patients who choose to avoid the cosmetic issues associated with PGA products.
Rhopressa® received FDA approval on December 18, 2017 and we launched Rhopressa® in the United States at the end of April 2018. Rhopressa® is now being sold to national and regional U.S. pharmaceutical distributors, and patients have access to Rhopressa® through pharmacies across the United States. We have obtained formulary coverage for Rhopressa® for approximately 90% of lives covered under commercial plans and approximately 40% of lives covered under Medicare Part D plans. We expect Medicare Part D Tier 2 equivalent coverage to increase to over 70% by the end of the first quarter of 2019.
In October 2018, we announced that the EMA accepted our MAA for review for Rhokiinsa®. Additionally, we completed a Phase 1 clinical trial and a positive safety profile. Our lead product candidate is once-daily, Rhopressa™ (netarsudil ophthalmic solution) 0.02%.successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which were designed to support meeting the requirements of Japan’s PMDA for potential regulatory submission of Rhopressa® in Japan. We successfully completed our secondare also planning to initiate a Phase 2 clinical trial on Japanese patients in Japan by the end of the first quarter of 2019 to support subsequent Phase 3 registration trial for Rhopressa™, named “Rocket 2,” in September 2015, which will be the pivotal trial for a New Drug Application, or NDA, filing with the U.S. Food and Drug Administration, or FDA,trials that we expect to submit in the third quarter of 2016. The primary clinical efficacy endpoint was to demonstrate non-inferiority of IOP lowering for Rhopressa™ compared to timolol in a 90-day efficacy period. The final primary baseline IOP ranges for Rocket 2 were above 20 mmHg, or millimeters of mercury, to below 25 mmHg. In addition to successfully achieving non-inferiority to timolol at this endpoint range, the recently reported topline 12-month safety data from Rocket 2 confirmed a positive safety profile for the drug and demonstrated a consistent IOP lowering effect throughout the 12-month period at the specified timepoint.

As background, the final primary endpoint range for Rocket 2 was updated from the original trial design, which included baseline IOPs of up to 27 mmHg. This change in endpoint range was made while Rocket 2 was in progress and prior to the database being locked, and was performed with FDA agreement. The reason for the change was the failure of our first Phase 3 registration trial for Rhopressa™, named “Rocket 1.” This 90-day efficacy trial did not meet its primary clinical efficacy endpoint of demonstrating non-inferiority of IOP lowering for Rhopressa™ compared to timolol at its primary range of above 20 mmHg to below 27 mmHg, which we reported in April 2015 (while Rocket 2 was already underway). Rocket 1 was successful at its pre-specified secondary endpoint range of above 20 mmHg and below 24 mmHg, and it was agreed by the FDA that Rocket 1, because of its success in meeting the secondary endpoint range, could be used as supportive to Rocket 2 for the upcoming NDA filing.

We are also conducting a third Phase 3 registration trial for Rhopressa™, named “Rocket 3,”expected to be conducted in Canada, whichJapan under our direction.
RocklatanTM
Our advanced-stage product candidate, RocklatanTM, is a supplementary 12-month safety-only trial and is not required for NDA filing purposes. In addition, we are conducting a fourth Phase 3 registration trial for Rhopressa™, named “Rocket 4,” in the U.S., which is designed to generate the six-month safety data that will be needed for European approval purposes, and is also not required for NDA filing purposes. We expect to report the topline 90-day interim efficacy data for Rocket 4 in the fourth quarter of 2016.

Our second product candidate is once-daily Roclatan™ (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005%. Roclatan™ is a fixed-dose combination of Rhopressa™Rhopressa® and latanoprost, which is the most commonly prescribed drug for the treatment of patients with glaucoma. It currently has one Phase 3 registration trial in process with a second about to start, after having successfully completed a Phase 2b clinical trial for patients with open-angle glaucoma and ocular hypertension in June 2014. In the Phase 2b clinical trial, Roclatan™ achieved its primary efficacy endpoint on day 29 and statistical superiority over individual components at all timepoints.glaucoma. We believe, Roclatan™based on our clinical data, that RocklatanTM has the potential to provide a greater IOP-loweringIOP-reducing effect than any currently approvedmarketed glaucoma product.medication. Therefore, we believe that RoclatanRocklatanTM, if approved and formulary coverage is obtained, could compete with both PGA and non-PGA therapies and become the product of choice for patients requiring maximal IOP lowering,reduction, including those with higher IOPs and those who present with significant disease progression despite using currently available therapies.

We submitted an NDA for RocklatanTM to the FDA in May 2018 under Section 505(b)(2) of the FDCA, which provides for an abbreviated approval pathway, since RocklatanTM is a fixed dose combination of two FDA-approved drugs in the United States. In July 2018, we announced that the NDA was accepted for review by the FDA and the PDUFA goal date was set for March 14, 2019.
The firstWith respect to RocklatanTM in jurisdictions outside the United States, we also initiated a Phase 3 registration trial for Roclatan™ RoclandaTM, named “Mercury 1,” commencedMercury 3, in September 2015. We expect to commence our second PhaseEurope during the third quarter of 2017. Mercury 3, registration trial for Roclatan™ , named “Mercury 2,” in March 2016. Mercury 1 is a 12-monthsix-month efficacy and safety trial which includes a 90-day interim efficacy readout and Mercury 2 is a 90-day efficacy trial. If both Mercury

1 and Mercury 2 are successful, we expect to file an NDA for Roclatan™ in the second half of 2017, approximately one year after the NDA filing for Rhopressa™.

We believe our clinical plans for both Rhopressa™ and Roclatan™ are already in place to satisfy European regulatory requirements. In addition to Rocket 1 and Rocket 2, the Rocket 4 trial, is designed to provide adequate six-month safety data for Rhopressa™compare RoclandaTM to meet European requirements. Based on our Rhopressa™ clinical plan, we expect to file for regulatory approval in Europe by mid-2017. While Mercury 1 and Mercury 2 will be used for European approval of Roclatan™Ganfort®, we also plan to initiate a third Phase 3 registration trial for Roclatan™, named Mercury 3,” in Europe in the first half of 2017. Mercury 3 will be designed to compare Roclatan™ to a fixed dosefixed-dose combination product broadly marketed in Europe which ifof bimatoprost, a PGA, and timolol, a beta blocker. If successful, shouldMercury 3 is expected to improve our commercialization prospects in Europe. We currently expect to read out topline 90-day efficacy data for the trial in 2019. Since RoclandaTM is a fixed-dose combination product that region.includes Rhokiinsa®, we plan to submit an MAA for RoclandaTM with the EMA if and when Rhokiinsa® is approved by the EMA. We expect to submit the MAA for RoclandaTM in early 2020, if the EMA has approved Rhokiinsa® by such time.

Pipeline Opportunities
Our stated objective is to build a major ophthalmic pharmaceutical company. In addition toWe are evaluating our primary product candidates, Rhopressa™ and Roclatan™, we are also exploring the longer-term impact of Rhopressa™ on the diseased trabecular meshwork, as well as neuroprotection, and evaluating possible uses of our existing proprietary portfolio of Rho Kinaseowned ROCK inhibitors for additional indications within and beyond glaucoma. In February 2015, we issued a research update on preclinical results demonstrating the potential for Rhopressa™ to have disease-modifying activity in glaucoma patients by stopping fibrosis in the trabecular meshwork, and also increasing perfusion in the trabecular outflow pathway thus increasing both drainage and the delivery of nutrients to the diseased tissue. Additionally, ourOur owned preclinical small molecule, AR-13154,AR-13503, is a ROCK and Protein kinase C inhibitor sustained-release implant with potential in the treatment of DME, wet AMD and related diseases of the retina. AR-13503, which has the same active metabolite as Rhopressa®, has shown lesion size decreases in an in

vivo preclinical model of wet AMD at levels similar to the current market-leading wet AMD anti-VEGF product. When used in combination preclinically with the market-leading anti-VEGF product, AR-13503 produced greater lesion size reduction than the anti-VEGF product alone in a model of proliferative DR. This molecule has not yet been tested in humans in a clinical trial setting. Pending additional studies, AR-13503 may have the potential to decrease lesion sizeprovide an entirely new mechanism and pathway to treat DME, wet AMD and related diseases of the retina. Since AR-13503 is a small molecule with a short half-life, and the aforementioned diseases are located in wet age-relatedthe back of the eye, a delivery mechanism is needed to deliver the molecule to the back of the eye for a sustained delivery period.
To that end, in July 2017, we announced that we entered into a collaborative research, development and licensing agreement with DSM, a global science-based company headquartered in the Netherlands. The research collaboration agreement includes an option to license DSM’s bio-erodible polymer implant technology for sustained delivery of certain Aerie compounds to treat ophthalmic diseases. In August 2018, we announced the expansion of our collaboration with DSM to provide for (i) a worldwide exclusive license for all ophthalmic indications to DSM’s polyesteramide polymer technology, (ii) continuation of the collaborative research initiatives through the end of 2020, including the transfer of DSM’s formulation technology to Aerie during that time and (iii) access to a preclinical latanoprost implant. This technology uses polyesteramide polymers to produce an injectable, thin fiber that is minute in size. Preclinical experiments have demonstrated early success in conjunction with AR-13503, including demonstration of linear, sustained elution rates over several months and achievement of target retinal drug concentrations. We expect to submit an IND for AR-13503 by the end of the first quarter of 2019.
Further, in October 2017, we acquired the rights to use PRINT® technology in ophthalmology and certain other assets from Envisia. PRINT® is a proprietary technology capable of creating precisely-engineered sustained release products utilizing fully-scalable manufacturing processes. In addition, we acquired Envisia’s intellectual property rights relating to Envisia’s preclinical dexamethasone steroid implant for the potential treatment of macular degeneration (AMD) at numerically higher levels thanedema due to RVO that also utilizes the PRINT® technology, which we refer to as AR-1105. The IND for this sustained-release implant was submitted in December 2018. In January 2019, we announced that the FDA reviewed the IND for AR-1105 and it is now in effect, allowing Aerie to initiate human studies in the treatment of macular edema due to RVO. We expect to initiate a current market-leading product.Phase 2 clinical study for AR-1105 in the first quarter of 2019.

We are also evaluating the PRINT® technology platform for sustained release of therapies to the front of the eye, including to treat glaucoma or ocular hypertension, as examples. We commenced operation of our cGMP-validated manufacturing facility for production of ophthalmic implants using PRINT® technology in our Durham, North Carolina, facility in October 2018.
We may continue to enter into research collaboration arrangements, license, acquire or develop additional product candidates and technologies to broaden our presence in ophthalmology. In August 2015ophthalmology, and September 2015, we entered into collaboration and license arrangements with GrayBug, Inc. and Ramot at Tel Aviv University, Ltd., respectively, neither of which represents a material financial commitment by Aerie. Our collaboration with GrayBug is focused on researching the potential use of their biodegradable polymer technology to deliver a version of AR-13154 to the back of the eye over a sustained period of time. With Ramot, we are evaluating a Ramot preclinical anti-beta amyloid small molecule, named EG-30, for neuroprotection in glaucoma and reduction of geographic atrophy in advanced dry AMD. We continually explore and discuss potential additional opportunities for new ophthalmic products, delivery alternatives and new therapeutic areas with potential partners. We are also currently screening our owned library of ROCK inhibitors for indications beyond ophthalmology considering that third-party studies and trials have demonstrated potential for ROCK inhibition in treating certain disease categories. We are initially focused on exploring potential opportunities for our molecules in pulmonary health, dermatology and cancers.

Financial Overview
Our strategy includes developingcash and cash equivalents totaled $202.8 million as of December 31, 2018. We believe that our business outside of North America, including obtaining regulatory approval on our owncash and cash equivalents and projected cash flows from revenues will provide sufficient resources for our lead product candidates in Europe and possibly obtaining regulatory approvalcurrent ongoing needs through at least the next twelve months, though there may be need for additional financing activity as we continue to grow, including the potential use of a partner in Japan. Regarding our international commercialization strategy, if our product candidates are successful, we may potentially commercialize ourselves or with a partner in Europe,the currently undrawn $100 million credit facility. See “—Liquidity and likely with a partner in Japan. We expect to finalize our European commercialization strategy by the end of 2016.
In March 2015, we revised our corporate structure to align with our business strategy outside of North America by establishing Aerie Pharmaceuticals Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands (“Aerie Limited”). In addition, we assigned the beneficial rightsCapital Resources” below and Note 9 to our non-U.S. and non-Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, we and Aerie Limited entered into a research and development agreement and cost sharing agreement pursuant to which we and Aerie Limited will share the costs of the development of intellectual property. Additionally,consolidated financial statements included elsewhere in April 2015, we continued to preparethis report for foreign-based activities and established Aerie Pharmaceuticals Ireland Limited (“Aerie Ireland Limited”) as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited. We are currently evaluating the possibility of constructing an Aerie manufacturing plant in Ireland.further discussion.
We have incurred net losses since our inception in June 2005. OurUntil 2018, when we commenced commercial operations, to date have beenour business activities were primarily limited to research and development and raising capital. As of December 31, 2015,2018, we had an accumulated deficit of $217.6$696.4 million. We recorded net losses of $74.4$232.6 million, $48.1$145.1 million and $31.1$99.1 million for the years ended December 31, 2015, 20142018, 2017 and 2013,2016, respectively. We anticipate that a substantial portion of ourOur capital resources and business efforts in the foreseeable future will beare largely focused on completingactivities relating to the development and obtaining regulatory approval and preparing for potential commercialization of Rhopressa®, advancing our product candidates.
We expectpipeline, international expansion and construction of our research and development expenses to increase as we continue to initiate and conduct clinical trials for our Rhopressa™ and Roclatan™ product candidates and pursue regulatory approval. As we prepare for commercialization, we will likely incur significant commercial, sales, marketing and manufacturing expenses. Since our initial public offering (“IPO”)facility in October 2013, we are also incurring additional expenses associated with operating as a public company. As a result, weAthlone, Ireland. We expect to continue to incur significant and increasing operating losses at least for the next several years.

Prioruntil our products generate adequate commercial revenue to our IPO, we raised net cash proceeds of $78.6 million from the private placement of convertible preferred stock and convertible notes. Prior to and in connection with our IPO, all outstanding shares of convertible preferred stock and all convertible notes were converted into shares of common stock. On October 30, 2013, we completed our IPO and raised net proceeds of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million.
Since our IPO, we have issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”), for which we received net proceeds of approximately $122.9 million, after deducting discounts and issuance costs of $2.1 million, and issued 1,754,556 shares of our common stock under our “at-the-market” sales agreements, for which we received net proceeds of approximately $50.5 million, after deducting commissions at a rate of up to 3% of the gross sales price per share sold and other fees and expenses.
Proceeds from our “at-the-market” sales in 2015, the 2014 Convertible Notes financing in September 2014, our IPO in October 2013 and any future sales under our current “at-the-market” sales agreements are currently expected to provide sufficient resources to complete all currently known non-clinical and clinical requirements for our development programs advancing Rhopressa™ and Roclatan™, approval by the FDA and product commercialization, pending successful outcome of the trials. We also intend to use the proceeds in part for general corporate purposes and potentially for strategic growth opportunities.

If we do not successfully commercialize Rhopressa®, or RocklatanTM or any of ourfuture product candidates, if approved, we may be unable to generate adequate product revenue orrevenues to achieve such profitability.
We may be required to draw down on the credit facility, or to obtain further funding through public or private offerings, debt financing, collaboration and licensing arrangementsor equity offerings or other sources.arrangements. Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on acceptable terms, we wouldmay be forced to delay, reduce or eliminate our research and development programs or commercialization or manufacturing efforts.
Financial Overview
Revenue
Product Revenues, Net
We launched Rhopressa® in the United States in late April 2018 and commenced generating product revenues from sales of Rhopressa® during the second quarter of 2018. Our product revenues are recorded net of provisions relating to estimates for (i) trade discounts and allowances, such as discounts for prompt payment and distributor fees, (ii) estimated rebates to Third-party Payers, estimated payments for Medicare Part D prescription drug program coverage gap (commonly called the “donut hole”), patient co-pay program coupon utilization, chargebacks and other discount programs and (iii) reserves for expected product returns. These estimates reflect current contractual and statutory requirements, known market events and trends, industry data and forecasted customer mix. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which may have an impact on earnings in the period of adjustment.
We will not generatedgenerate any revenue from the sale ofRocklatanTM or any products,future product candidates unless and we do not expect to generate any revenue unless or until we obtain regulatory approval of and commercialize oursuch products.
Cost of Goods Sold
Cost of goods sold consists of direct and indirect costs to procure and manufacture Rhopressa® product sold, including third-party manufacturing costs. We began capitalizing inventory costs for Rhopressa® after receipt of FDA approval of Rhopressa® on December 18, 2017. Prior to receiving FDA approval, such costs were expensed as pre-approval commercial manufacturing expenses. Cost of goods sold in 2019 will continue to be favorably impacted by sales of Rhopressa® inventory that was expensed prior to FDA approval; however, we do not expect the impact to be material.
Selling, General and Administrative Expenses
GeneralSelling, general and administrative expenses consist primarily of employee-related expenses, including salaries, benefits and stock-based compensation for all officers and employees in general management, sales and marketing, finance and administration. Other significant expenses include selling and marketing expenses, facilities expenses, shipping and handling costs and professional fees for accounting,audit, tax, legal and other services.
We expect that our selling, general and administrative expenses will increase with the continued advancementmodestly for 2019 as compared to 2018 reflecting a full year of our product candidates and with our increased management, legal, compliance, accounting and investor relations expenses as we continue to grow. We expect these increases will likely include higher expenses for insurance, expenses related to our sales force.
Pre-approval Commercial Manufacturing Expenses
Pre-approval commercial manufacturing expenses consist of costs incurred for commercial-related manufacturing activities for Rhopressa® and RocklatanTMprior to FDA approval. These costs include those associated with the hiringmanufacturing of inventory in anticipation of commercial launch, expenses associated with the establishment of both our manufacturing plant in Athlone, Ireland, and our additional API and drug product contract manufacturers, as well as employee-related expenses, which includes salaries, benefits and stock-based compensation for commercial-related manufacturing personnel prior to regulatory approval.
If we obtain regulatory approval of our additional API and paymentsdrug product contract manufacturers in the first half of 2019, we expect that our pre-approval commercial manufacturing expenses will decrease in 2019 as compared to outside service providers, lawyers and accountants.2018 as the cost of commercial material produced by these manufacturers following regulatory approval will be capitalized as inventory.
Research and Development Expenses
Since our inception, we have focused on ourWe expense research and development programs.costs to operations as incurred. Research and development expenses consist primarily of costs incurred for the research and development of our preclinical and clinical candidates, which include:
employee-related expenses, including salaries, benefits, travel and stock-based compensation expense for research and development personnel;
expenses incurred under agreements with contract research organizations (“CROs”),CROs, contract manufacturing organizations and service providers that assist in conducting clinical trials and preclinical studies;
costs associated with any collaboration arrangements, licenses or acquisitions of preclinical molecules, product candidates or technologies;
costs associated with preclinical activities and development activities;
costs associated with regulatory operations; and

63


depreciation expense for assets used in research and development activities.
We expense research and development costs to operations as incurred. The costs for certain development activities, such as clinical trials, are recognized based on the terms of underlying agreements as well as an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations along with additional information provided to us by our vendors.
Expenses relating to activities, such as manufacturing and stability and toxicology studies, that are supportive of the product candidate itself, are classified as direct non-clinical. Expenses relating to clinical trials and similar activities, including costs associated with CROs, are classified as direct clinical. Expenses relating to activities that support more than one development program or activity such as personnel costs, stock-based compensation, facilities and depreciation are not allocated to direct clinical or non-clinical expenses and are separately classified as “unallocated.”
The following table shows our research and development expenses by product candidate and by type of activity for the years ended December 31, 2015, 2014 and 2013:

For the periods presented, we did not incur significant direct non-clinical or direct clinical costs for our exploration of the impact of Rhopressa™ on the diseased trabecular meshwork and neuroprotection or for possible uses of our existing proprietary portfolio of Rho Kinase inhibitors beyond glaucoma. Costs for these activities were primarily comprised of internal personnel costs and were included in unallocated expenses. Costs associated with our current collaboration arrangements were also included in unallocated expenses. Discontinued product candidates relate to previously developed AR-12286 and related compounds for which further development for the treatment of glaucoma was discontinued in 2013.
Research and development activities associated with the discovery and development of new drugs and products for the treatment of diseases of the eye are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase as we continue to conduct clinical trials for our product candidates, or if the FDA requires us to conduct additional trials for approval, and explore additional product candidates and technologies to broaden our presence in ophthalmology.
Our research and development expenditures are subject to numerous uncertainties in timing and cost to completion. Development timelines, the probability of success and development expenses can differ materially from expectations. The cost of clinical trials may vary significantly over the life of a project as a result of differences arising during clinical development, including, among others, the following:
number of trials required for approval;

64


number of sites included in the trials;
length of time required to enroll suitable patients;
number of patients that participate in the trials;
drop-out or discontinuation rates of patients;
duration of patient follow-up;
costs related to compliance with regulatory requirements;
number and complexity of analyses and tests performed during the trial;
phase of development of the product candidate; and
efficacy and safety profile of the product candidate.
Our expenses related to clinical trials are based on estimates of patient enrollment and related expenses at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with research institutions, consultants and CROs that assist in conducting and managing clinical trials. We generally accrue expenses related to clinical trials based on contracted amounts applied to the level of patient enrollment and activity according to the protocol. If future timelines or contracts are modified based upon changes in the clinical trial protocol or scope of work to be performed, we modify our estimates of accrued expenses accordingly on a prospective basis. Historically, such modifications have not been material.
As a result of the uncertainties discussed above, we are unable to determine with certainty the duration and completion costs ofWe expect that our development programs or precisely when and to what extent we will receive revenue from the commercialization and sale of our product candidates. We may never succeed in achieving regulatory approval for one or more of our product candidates.

Other Income (Expense), Net
Other income (expense) primarily includes interest income, interest expense, foreign exchange gains and losses, and other income and expense. Interest income primarily consists of interest earned on our cash, and cash equivalents and investments, as well as the net proceeds from the saleand amortization or accretion of discounts and premiums on our net operating loss tax benefits for the state of New Jersey. Refer to Note 3 to our audited consolidated financial statements appearing elsewhere in this report for further information.

Otherinvestments. Interest expense consists of interest expense under our convertible notes, including the 2014 Convertible Notes, including the amortization of debt discounts and issuance costs incurred prior to the conversion of the 2014 Convertible Notes on July 23, 2018. Interest expense also includes the amortization of issuance costs and other miscellaneous expense.commitment fees incurred on the credit facility entered into on July 23, 2018. Foreign exchange gains and losses are primarily due to the remeasurement of our Euro-denominated liability related to our build-to-suit lease obligation, which is held by a subsidiary with a U.S. dollar functional currency. Other expense includes the value of additional shares of Aerie common stock issued to complete the conversion of the 2014 Convertible Notes in July 2018. See Note 9 to our consolidated financial statements included elsewhere in this report for additional information.
Critical Accounting Policies and Use of Estimates
Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States or (“U.S. GAAP.GAAP”). The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, costs and expenses and related disclosures. We evaluate our estimates and judgments on an ongoing basis. Significant estimates include assumptions used in the determination of revenue recognition, inventories, accrued expenses, fair value measurements, acquisitions and stock-based compensation and certain research and development expenses.compensation. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Our significant accounting policies are more fully described in Note 2 to our audited consolidated financial statements included elsewhere in this report. The following accounting policies are the most critical in fully understanding and evaluating our reported financial results and affect significant judgments and estimates that we use in the preparation of our financial statements.

Revenue Recognition
65

TableWe recognize revenue when our customers obtain control of Contentsour product in an amount that reflects the consideration we expect to receive from our customers in exchange for that product. To determine revenue recognition for contracts that are determined to be in scope of the Financial Accounting Standards Board Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”), we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy the performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services transferred to our customer. Once the contract is determined to be within the scope of ASC Topic 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied. Shipping and handling costs related to our product sales are included in selling, general and administrative expenses.
Net product revenues for the year ended December 31, 2018, were derived from sales of Rhopressa® in the United States to customers, which principally include a limited number of national and select regional wholesalers (the “Distributors”). These Distributors subsequently resell the product, primarily to retail pharmacies that dispense the product to patients. We expense

incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less or the amount is immaterial. The product that is ultimately used by patients is generally covered by third-party payers, such as government or private healthcare insurers and pharmacy benefit managers (“Third-party Payers”) and may be subject to rebates and discounts payable directly to those Third-party Payers.
Product revenue is recorded net of trade discounts, allowances, rebates, chargebacks, estimated returns and other incentives, discussed below. These reserves are classified as either reductions of accounts receivable or as current liabilities. Amounts billed or invoiced are included in accounts receivable, net on the consolidated balance sheet. We did not have any contract assets (unbilled receivables) at December 31, 2018, as customer invoicing generally occurs before or at the time of revenue recognition. We did not have any contract liabilities at December 31, 2018, as we did not receive payments in advance of fulfilling our performance obligations to our customers.
Net product revenue is typically recognized when the Distributors obtain control of our product, which occurs at a point in time, typically upon delivery of Rhopressa® to the Distributors. For the year ended December 31, 2018, three Distributors accounted for 33.9%, 33.3% and 29.7% of total revenues, respectively. We evaluate the creditworthiness of each of our Distributors to determine whether it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur. We do not assess whether a contract has a significant financing component if the expectation is such that the period between the transfer of the promised goods to the customer and the receipt of payment will be less than one year. Standard credit terms do not exceed 75 days.
We calculate our net product revenue based on the wholesale acquisition cost that we charge our Distributors for Rhopressa® less provisions for (i) trade discounts and allowances, such as discounts for prompt payment and Distributor fees, (ii) estimated rebates to Third-party Payers, estimated payments for Medicare Part D prescription drug program coverage gap (commonly called the “donut hole”), patient co-pay program coupon utilization, chargebacks and other discount programs and (iii) reserves for expected product returns. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, known market events and trends, industry data and forecasted customer mix. Provisions for revenue reserves reduced product revenues by $19.6 million in aggregate for the year ended December 31, 2018. The transaction price may be subject to constraint and is included in the net product revenues only to the extent that it is probable that a significant reversal of the amount of the cumulative revenues recognized will not occur in a future period. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which could have an impact on earnings in the period of adjustment.
Trade Discounts and Allowances: We generally provide discounts on sales of Rhopressa® to our Distributors for prompt payment and pay fees for distribution services and for certain data that Distributors provide to us. We expect our Distributors to earn these discounts and fees, and accordingly deduct the full amount of these discounts and fees from our gross product revenues at the time such revenues are recognized.
Rebates, Chargebacks and Other Discounts: We contract with Third-party Payers for coverage and reimbursement of Rhopressa®. We estimate the rebates and chargebacks we expect to be obligated to provide to Third-party Payers and deduct these estimated amounts from our gross product revenue at the time the revenue is recognized. We estimate the rebates and chargebacks that we expect to be obligated to provide to Third-party Payers based upon (i) our contracts and negotiations with these Third-party Payers, (ii) estimates regarding the payer mix for Rhopressa® and (iii) historical industry information regarding the payer mix for comparable pharmaceutical products and product portfolios. Other discounts include our co-pay assistance programs for commercially-insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that we expect to pay associated with product that has been recognized as revenue.
Product Returns: We estimate the amount of Rhopressa® that will be returned and deduct these estimated amounts from our gross revenue at the time the revenue is recognized. We currently estimate product returns based on historical industry information regarding rates for comparable pharmaceutical products and product portfolios, the estimated remaining shelf life of Rhopressa® shipped to Distributors, and contractual agreements with our Distributors intended to limit the amount of inventory they maintain. Reporting from the Distributors includes Distributor sales and inventory held by Distributors, which provide us with visibility into the distribution channel to determine when product would be eligible to be returned.
Inventories
Manufacturing costs related to commercial production are expensed as pre-approval commercial manufacturing expenses before we obtain regulatory approval for our product candidates. Once regulatory approval is obtained, such costs are capitalized as inventory. Inventories are stated at the lower of cost or net realizable value. We determine the cost of inventory

using the first-in, first-out (“FIFO”) method. We analyze our inventory levels at least quarterly and write down inventory that is expected to expire prior to being sold, inventory in excess of expected sales requirements and inventory that fails to meet commercial sale specifications, with a corresponding charge to cost of goods sold. The determination of whether inventory costs will be realizable requires estimates by management of future expected inventory requirements based on sales forecasts. If actual net realizable value is less than our estimate or if actual market conditions are less favorable than our projections, additional inventory write-downs may be required. Charges for inventory write-downs are not reversed if it is later determined that the product is saleable.
Accrued Expenses
As part of the process of preparing our consolidated financial statements, we are required to estimate accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with applicable vendor personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples of estimated accrued expenses include:
fees paid to CROs in connection with clinical trials;
fees paid to investigative sites in connection with clinical trials; and
fees paid to contract manufacturing organizations and service providers that assist in conducting preclinical and clinical trials.trials or that produce commercial inventory prior to FDA approval; and
fees paid to service providers for audit, tax, legal and other services.
We accrue our expenses related to clinical trials based on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct research activities and/or manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the level of effort varies from our estimate, we will adjust the accrual accordingly.
If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. Although we do not currently anticipate the future settlement of existing accruals to differ materially from our estimates, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low for any period. There have been no material changes in estimates for the periods presented.
Fair Value Measurements
We record certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair valueAs of our financial instruments, including cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses approximate their respective carrying values due toDecember 31, 2017, the short-term nature of these instruments. The carrying amounts of long-term investments represent their estimated fair values. The estimated fair value of the 2014 Convertible Notes was $140.1 million$327.6 million. In July 2018, the entire outstanding principal amount of the 2014 Convertible Notes was converted into shares of Aerie common stock. See Note 9 to our consolidated financial statements included elsewhere in this report for additional information.
Acquisitions
We evaluate acquisitions to determine whether the acquisition is a business combination or an acquisition of assets under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 805: Business Combinations (“ASC Topic 805”). Business combinations are accounted for using the acquisition method of accounting, whereby assets acquired and $163.8 millionliabilities assumed are recorded as of December 31, 2015the acquisition date at their respective fair values and 2014, respectively. Asany excess of December 31, 2015the fair value of the consideration transferred over the fair value of the net assets acquired is recorded as goodwill. In an asset acquisition that does not constitute a business, no goodwill is recognized, and 2014,the net assets acquired are generally recorded at cost. In January 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). The ASU clarifies the definition of a business and provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all outstanding warrants are classifiedof the fair value

of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The new standard was effective for us beginning on January 1, 2018; however, we elected to early adopt this ASU as equityof July 1, 2017. Under ASC Topic 805, including the provisions of ASU 2017-01, the October 4, 2017 transaction to acquire assets from Envisia was determined to meet the criteria of an asset acquisition rather than a business combination, resulting in a $24.8 million charge to research and are recorded within additional paid-in capitaldevelopment expense on the consolidated balance sheets.statement of operations and comprehensive loss in the three months ended December 31, 2017 for acquired in-process research and development (“IPR&D”). Significant judgment is required in estimating the fair value of intangible assets and in a determination of whether an acquisition is a business combination or an acquisition of assets. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management but are inherently uncertain.
Stock-Based Compensation
We recognize compensation costs related to stock options granted to employees ratably over the requisite service period, which in most cases is the vesting period of the award for employees, based on the estimated fair value of the awards on the date of grant. Compensation expense for options granted to non-employees is determined as the fair value of consideration received or the fair value of the equity instruments issued, whichever is more reliably measured. The fair value of the awards granted to non-employees is re-measuredremeasured each period until the related service is complete. Compensation expense related toThe fair value of restricted stock awards (“RSAs”), including restricted stock awards with non-market performance and service conditions (“PSAs”) is determined based on the marketfair value of our common stock on the grant date andof grant. Compensation expense related to RSAs is expensedrecognized ratably over the vesting period. As the PSAs have multiple performance conditions, compensation expense is recognized for each vesting tranche over the respective requisite service period of each tranche if and when we deem it probable that the performance conditions will be satisfied. Compensation expense for stock purchase rights under our employee stock purchase plan is measured and recognized on the date that we become obligated to issue shares of our common stock and is based on the difference between the fair value of our common stock and the purchase price on such date.
Stock-based compensation expense was $12.9 million, $9.2 million and $2.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015, we had $29.9 million of unrecognized compensation expense.
The intrinsicfair value of allthe stock options outstandingappreciation rights (“SARs”) is estimated using the Black-Scholes option pricing model and is marked to market through stock-based compensation expense. SARs are liability-based awards as of December 31, 2015 was $55.9 million, of which $37.3 million and $18.6 million related to stock options that were vested and unvested, respectively, at that date.they may only be settled in cash.

Significant Factors, Assumptions and Methodologies Used in Determining Fair Value
Determining the appropriate fair value measurement of stock-based awards requires the use of subjective assumptions. In the absence of a public trading market for our common stock prior to the completion of our IPO, we conducted periodic assessments of the valuation of our common stock. The determination ofWe estimate the fair value measurement of options to purchase common stock using the Black-Scholes option pricing model, which is affected by our estimated common stock fair values as well as assumptions regarding a number of other subjective variables. These other variables include the expected term of the options, our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends.
We estimatedestimate the fair value of stock options at the grant date using the following assumptions:
Fair Value of our Common Stock. For all stock options granted after the completion of our IPO, theThe fair value for our underlying common stock is determined using the closing price on the date of grant as reported on theThe NASDAQ Global Market. For all stock options granted prior to the completion of our IPO, the fair value for our underlying common stock was determined by our board of directors in its sole discretion based on recommendations from management and taking into account advice and assistance provided by third-party valuation consultants engaged to assist us in connection with such valuations.
Volatility. We calculate expected volatility based on our historical volatility in combination with reported data for a selected group of similar publicly traded companies, or guideline peer group, for which the relevant historical information is available. We selected representative companies from the pharmaceutical industry with similar characteristics to us, including stage of product development and therapeutic focus. We will continue to use a combination of our historical volatility and the guideline peer group volatility information for the foreseeable future.commercialization.
Expected Term. We used the simplified method as prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, as we do not have sufficient historical exercise and post-vesting termination data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The midpoint between the vesting date and the maximum contractual expiration date is used as the expected term under this method.
Risk-free Rate. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected time to exercise.
Forfeiture. Forfeitures are recognized in the period in which they occur. Prior to 2017, forfeitures were estimated such that we only recognizerecognized expense for the shares expected to vest, and adjustments arewere made if actual forfeitures differdiffered from those estimates. We estimate our annual forfeiture rates based on our historical analysis of actual stock option forfeitures and our future expectations.

Dividend Yield. Except for a one-time cash dividend related to the spin-off of certain non-core intellectual property that occurred in 2012, we have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future.
The estimation of the number of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period in which estimates are revised.

Stock Purchase Warrants
We account for our stock purchase warrants as either equity or liabilities based upon the characteristics and provisions of the underlying instruments. Warrants classified as equity are recorded at their fair value on the date of issuance as additional paid-in capital on the consolidated balance sheets and no further adjustments are made to their valuation. Warrants classified as liabilities are recorded at their fair value on the date of issuance and are re-measured on each subsequent balance sheet date until the earlier of the exercise or expiration of the applicable warrants or until such time that the warrants are no longer determined to be derivative instruments. The fair value changes are recognized as income (decreases in fair value) or expense (increases in fair value) in Other income (expense), net in the consolidated statements of operations and comprehensive loss. The fair value of these liabilities is estimated using the Black-Scholes method, which, under our facts and circumstances, approximates, in all material respects, the values determined when using a Monte Carlo simulation.
The Black-Scholes method and the Monte Carlo simulation require the use of subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk free interest rate and the fair value of the underlying equity securities. The fair value of the underlying common stock is determined as discussed above under “—Stock-Based Compensation.”

Due to our three year cumulative loss position, history of operating losses and lack of available evidence supporting future taxable income, we believe thatmaintain a valuation allowance on all of our deferred tax assets as of December 31, 2015 remains appropriate.2018, with the exception of a release of valuation allowance during the year ended December 31, 2017 on a deferred tax asset related to a $1.7 million AMT refund that we expect to receive under the Tax Act. The amount of refund expected to be received is recorded as a receivable as of December 31, 2018 and 2017.

Liquidity and Capital Resources
Since our inception, we have funded operations primarily through the sale of equity securities including our IPO, and the issuance of convertible notes. We have incurred losses and experienced negative operating cash flows since our inception and anticipate that we will continue to incur losses for at least the next two to three years, or until such a time when one or more of our product candidatesproducts are commercially successful, if at all. We received FDA approval for Rhopressa® on December 18, 2017 and we launched Rhopressa® in the United States at the end of April 2018. As a result, we commenced generating product revenues related to sales of Rhopressa® in the second quarter of 2018. We will not generate any revenue from RocklatanTM or any future product candidates unless and until we obtain regulatory approval and commercialize such products. RocklatanTM has a PDUFA goal date of March 14, 2019.
Prior toSources of Liquidity
Since our IPO, we raised net cash proceeds of $78.6 million from the private placement of convertible preferred stock and convertible notes. Prior to andinitial public offering in connection with our IPO, all outstanding shares of convertible preferred stock and all convertible notes were converted into shares of common stock.
On October 30, 2013, we completed our IPO and issued 7,728,000 shares of our common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over- allotments.

This includes approximately $207.7 million of net proceeds from our prior “at-the-market” sales agreements, of which approximately $61.1 million were received during the year ended December 31, 2017, and approximately $143.6 million of net proceeds from the issuance of the 2014 Convertible Notes of approximately $122.9 million, after deducting discounts and issuance costs of $2.1 million.
On November 3, 2014, we filed a shelf registration statement on Form S-3 that permits: (i) the offering, issuance and sale by us of up to a maximum aggregate offering price of $150.0 million of the our common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale by us of up to a maximum aggregate offering price of $50.0 millionshares of our common stock that may be issued and sold by us under an “at-the-market” sales agreement with Cantor Fitzgerald & Co.

On November 6, 2015, we filed a prospectus supplement to the base prospectus dated November 10, 2014. The prospectus supplement permits the offering, issuance and sale of up to a maximum aggregate offering price of $50.0 million of our common stock that may be issued and sold by us under separate “at-the-market” sales agreements with RBC Capital Markets, LLC and Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by us under the “at-the-market” sales agreements is included in the $150.0 million of common stock that may be offered, issued and sold by us under the shelf registration statement.

There were no sales of securities registered pursuant to the shelf registration statement forduring the year ended December 31, 2014.2018, for which we received net proceeds of approximately $136.4 million, after deducting fees and expenses. This includes approximately $62.3 million of net proceeds from our “at-the-market” sales agreement (“ATM”) and approximately $74.1 million of net proceeds from the issuance of shares of our common stock pursuant to an underwriting agreement, dated January 23, 2018, related to a registered public offering, and

In July 2018, we entered into a $100 million senior secured delayed draw term loan facility that matures on July 23, 2024. No funds were drawn at closing or as of December 31, 2018. See Note 9 to our consolidated financial statements included in this report for additional information. We believe that our cash and cash equivalents and investments as of December 31, 2015 and any future sales under our current “at-the-market” sales agreementsprojected cash flows from revenues will provide sufficient resources to complete all currently known non-clinical and clinical requirements for our development programs advancing Rhopressacurrent ongoing needs through at least the next twelve months. See “—TMOperating Capital Requirements and RoclatanTM, approval by the FDA and product commercialization, pending successful outcome of the trials. Our ability to continue as a going concern will depend, in large part, on our ability to successfully commercialize our product candidates and generate positive cash flow from operations, neither of which is certain..”

Operating Capital Requirements
We expect to incur increasingongoing operating losses until such a time when Rhopressa® or RocklatanTM or any other product, if approved in the future, generates adequate revenues to render Aerie profitable.
Our principal liquidity requirements are for: working capital; operating expenses including for at leastcommercialization and manufacturing activities; expenses associated with developing our pipeline opportunities, including pursuing strategic growth opportunities; costs associated with executing our international expansion strategy, including clinical and potential commercialization activities in Europe and Japan; contractual obligations; and capital expenditures, including completing our manufacturing plant in Ireland.
In January 2017, we entered into a lease agreement for a new manufacturing plant in Ireland under which we are leasing approximately 30,000 square feet of interior floor space for build-out. Capital expenditures related to the next several years as we continuemanufacturing plant

We currently expectbelieve that our existing cash and cash equivalents and investments and availability under our current “at-the-market” sales agreementsprojected cash flows from revenues will provide sufficient resources to complete allsupport ouroperationsthrough at least the next twelve months. Additionally, we have the borrowing capacity of up to $100 million under a delayed draw term loan facility. The first two years of payments on any drawn amounts will be on an interest-only basis. We do not currently known non-clinicalintend to draw down on the credit facility but may do so if and clinicalas needed.

We may need to obtain additional financing to fund our future operations, including supporting our international operations and sales and marketing activities, as well as funding the ongoing development of any additional product candidates or technologies that we might license, acquire or develop internally. To the extent that we raise additional capital through the sale of common stock, convertible securities or other equity securities, the ownership interests of our existing stockholders may be materially diluted and the terms of these securities could include liquidation or other preferences that could adversely affect the rights of our existing stockholders.

Net Operating Loss Carry-ForwardsCarryforwards
We have incurred significant net operating lossesNOLs since our inception in June 2005. We expect to continue to incur net operating lossesNOLs until such a time when Rhopressa® or RocklatanTM or any other product, if approved in the future, generates adequate revenues to render Aerie profitable. We received FDA approval for Rhopressa® on December 18, 2017, and we launched Rhopressa® in the foreseeable future as we continue to develop our product portfolio, seek regulatory approval, and, if such approval is obtained, prepare to commercialize our products.
In March 2015, we revised our corporate structure to align with our business strategy outsideUnited States at the end of North America and consummated the IP Assignment. Largely asApril 2018. As a result, we commenced generating product revenues related to sales of Rhopressa® in the IP Assignment,second

quarter of 2018; however, we reversed approximately $29.5 million of our valuation allowance on certain deferred tax assets, primarily federal and state net operating losses, as of December 31, 2015.did not generate taxable income in 2018. The NOLs may be utilized to offset taxable income generated in the future.
As of December 31, 2015,2018, we had federal and state NOL carryforwards of approximately $61.1$387.7 million of net operating loss carry-forwards whichand $411.2 million, respectively. Federal NOLs that arose prior to 2018 and state NOLs will begin to expire at various dates beginning in 2031 and 2024, if not utilized.respectively. Federal NOLs that arose on or after January 1, 2018, can be carried forward indefinitely to be utilized against future income, but can only be used to offset a maximum of 80% of our federal taxable income in any year. As of December 31, 2018, we had foreign NOL carryforwards of $44.1 million, which are available solely to offset taxable income of our foreign subsidiaries, subject to any applicable limitations under foreign law.
Net operating lossNOLs and tax credit carry-forwardscarryforwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities and may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions.amended. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of our company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years.
Certain transactions occurred in 2015 State NOLs and prior years that resulted in ownership changes as defined under Section 382 and similar state provisions which will limit the future use of certain federal and state net operating loss carry-forwards. Those federal and state net operating losses that are not limited are included as deferred tax assets and have been fully offset by a valuation allowance as of December 31, 2015, as we believe, based on our history of operating losses, it is more likely than not that the tax benefits will not be realized.

Jumpstart Our Business Startups Act of 2012
The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) provides that an emerging growth company can take advantage of certain exemptions from various reporting and other requirements that are applicable to public companies that are not emerging growth companies. We currently take advantage of some, but not all, of the reduced regulatory and reporting requirements that are available to us for as long as we qualify as an emerging growth company. We have irrevocably elected under Section 107 of the JOBS Act not to take advantage of the extension of time to comply with new or revised financial accounting standards available under Section 102(b) of the JOBS Act and, therefore, we willcredit carryforwards may be subject to similar limitations under state laws.
In December 2017, the sameTax Act was signed into law and enacted significant changes to the Internal Revenue Code of 1986, as amended. This new or revised accounting standards astax legislation, among other public companies that are not emerging growth companies. Our independent registered public accounting firm will not be requiredchanges, reduced the federal corporate income tax rate from 35% to provide an attestation report on the effectiveness of our internal control over financial reporting for as long as we qualify as an emerging growth company.
Recent Accounting Pronouncements
In November 2015, the Financial Accounting Standards Board (the “FASB”) issued ASU 2015-17, which requires that all21% effective January 1, 2018.Under U.S. GAAP, deferred tax assets and liabilities along with any relatedare required to be revalued during the period in which the new tax legislation is enacted, which resulted in the remeasurement of our federal deferred tax assets and liabilities as of December 31, 2017 to reflect the effects of the enacted changes in tax rate. As we provide a full valuation allowance be classified as noncurrent on the balance sheet. The guidance is effective for annual periods beginning after December 15, 2016,our net deferred tax assets, there was no impact to income tax expense in our consolidated statement of operations and all annual and interim periods thereafter, with early adoption permitted. We early adopted this guidancecomprehensive loss for the year ended December 31, 2015.2017 as a result of the remeasurement. The adoptionTax Act also repealed the corporate AMT for tax years beginning after December 31, 2017 and provides that existing AMT credit carryovers are refundable in tax years beginning after December 31, 2017. We have approximately $1.7 million of AMT credit carryovers that we expect to be fully refunded between 2019 and 2022. The Tax Act also limits various business deductions, modifies the maximum deduction of NOLs and includes various international tax provisions. Many provisions in the Tax Act were generally effective in tax years beginning in 2018, and we will continue to analyze additional information and guidance related to certain aspects of the Tax Act in assessing the potential impact on Aerie in the future.
Indebtedness
In July 2018, our $125.0 million aggregate principal amount of 2014 Convertible Notes was converted into shares of Aerie common stock. Also, in July 2018, we entered into a $100 million senior secured delayed draw term loan facility, pursuant to which we may borrow up to $100 million in aggregate in one or more borrowings at any time prior to July 23, 2020. The credit facility includes fees upon drawdown of 1.75% of amounts drawn, an 8.625% annual interest rate on drawn amounts, and annual fees on undrawn amounts of 1.5%. There is also an exit fee of $1.5 million payable upon termination of the credit facility (whether at maturity or otherwise). Fees on undrawn amounts are not payable until July 23, 2020, and no principal payments will be due on drawn amounts, if any, until July 23, 2020. The credit facility matures on July 23, 2024 in respect of drawn amounts. The credit facility includes affirmative and negative covenants and prepayment terms. No amounts were drawn at closing or as of December 31, 2018. See Note 9 to our consolidated financial statements appearing elsewhere in this guidance,report for more information.

(1)Our lease obligations are primarily related to our principal executive office and research facility in Durham, North Carolina, and corporate offices in Bedminster, New Jersey, Irvine, California and other foreign offices. Additionally, the table reflects rental payments related to a lease agreement we entered into in January 2017 for a new manufacturing plant in Athlone, Ireland, under which we are leasing approximately 30,000 square feet of interior floor space for build-out. We are permitted to terminate the lease agreement beginning in September 2027. Obligations denominated in foreign currencies have been translated to U.S. dollars at the foreign exchange rates in effect at December 31, 2018.
(2)In July 2018, the entire outstanding principal amount of the 2014 Convertible Notes was converted into shares of Aerie common stock. Also, in July 2018, we entered into a credit facility, which matures on July 23, 2024. The credit facility includes fees upon drawdown of 1.75% of amounts drawn, an 8.625% annual interest rate on drawn amounts, and annual fees on undrawn amounts of 1.5%. There is also an exit fee of $1.5 million payable upon termination of the credit facility (whether at maturity or otherwise). No funds were drawn at closing or as of December 31, 2018, and therefore, fees included in the table above relate to fees due on undrawn amounts, including the exit fee. Refer to Note 9 to our consolidated financial statements included elsewhere in this report for further information.
(3)Purchase obligations primarily include non-cancelable commitments under our contract manufacturing agreements.
We have agreements with third-parties with contingent milestone payments that are potentially payable by us, as more fully described in Note 1 to our consolidated financial statements appearing elsewhere in this report, which was applied retrospectivelyare not reflected in the table above. These payments are contingent upon achieving certain development and/or regulatory milestones that may or may not ever be achieved. Therefore, our requirement to make such payments in the future, if at all, as well as the timing of any such payments is highly uncertain. 
Off-Balance Sheet Arrangements
We did not have a materialduring the periods presented, and we do not currently have, any off-balance sheet arrangements as defined under SEC regulations.
Recent Accounting Pronouncements
See Note 2 to our consolidated financial statements included elsewhere in this report regarding the impact of certain recent accounting pronouncements on our consolidated financial statements.
In April 2015, the FASB issued ASU 2015-03, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt, consistent with the presentation of a debt discount. The guidance is effective for annual periods beginning after December 15, 2015, and all annual and interim periods thereafter. As permitted, we early adopted this guidance for the year ended December 31, 2015. The adoption of this guidance, which was applied retrospectively and impacted consolidated balance sheet presentation only, resulted in a reclassification of $1.3 million from Other assets, net to a direct deduction from the carrying amount of the 2014 Convertible Notes on the consolidated balance sheet as of December 31, 2014.
In August 2014, the FASB issued ASU 2014-15, which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for us for the annual period ending after December 15, 2016 and for annual and interim periods thereafter, with early adoption permitted. We are currently evaluating the impact of this accounting standard update on our financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. Our cash and cash equivalents as of December 31, 2015, totaled $91.1 million and consisted primarily of cash and money market funds with original maturities of three months or less from the date of purchase. Our investments totaled $59.3 million as of December 31, 2015 and consisted of certificates of deposit, commercial paper corporate bonds and government agency securities.funds. We had cash and cash equivalents and investments of $158.2 million as of December 31, 2014.do not currently engage in any hedging activities against changes in interest rates. Given the short-term nature of our cash and cash equivalents, and investments and our investment policy,we do not believe that a sudden change in market interest rates would not be expected to have a material impact on our financial condition or results of operations. We do not engage inAny amounts drawn under the credit facility, if any, hedging activities against changes in interest rates. The 2014 Convertible Noteswill carry a fixed interest rate and, as such, arewill not be subject to interest rate risk.
We face market risks attributable to fluctuations in foreign currency exchange rates and exposure on the remeasurement of foreign currency-denominated monetary assets or liabilities into U.S. dollars. In particular, our operations and subsidiary in Ireland may enter into certain obligations or transactions in Euros or other foreign currencies but has a U.S. dollar functional currency. We do not currently have any materialderivative instruments or a foreign currency or other derivativehedging program. To date and during the year ended December 31, 2018, foreign currency exposure and foreign currency financial instruments.instruments have not been material.

ITEM 9A. CONTROLS AND PROCEDURES
Evaluation of disclosure controlsDisclosure Controls and procedures.Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15(d)-15(e)), as of the end of the period covered by this report. Based upon the evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of such period,December 31, 2018, the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file andor submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs.
Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, our principal executive officer and principal financial officer and effected by our boardBoard of directors,Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in conformity with generally accepted accounting principles and includes those policies and procedures that:

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; 

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.


74



Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Under the supervision of and with the participation of our principal executive officerChief Executive Officer and principal financial officer,Chief Financial Officer, our management assessed the effectiveness of our internal control over financial reporting as of December 31, 20152018 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013 in Internal Control-Integrated Framework (2013). Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2015.2018.
This annual report on Form 10-K does not include an attestation reportThe effectiveness of our internal control over financial reporting as of December 31, 2018 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, regarding internal control over financial reporting.

Changes in Internal Control Over Financial Reporting
During the fourth quarter of 2015, we implemented an enterprise resource planning (ERP) system on a world-wide basis to support our future growth and to integrate significant processes. In connection with the implementation of the ERP system, we updated the processes that constitute our internal control over financial reporting, as necessary, to accommodate related changes to our business processes and accounting procedures. This implementation involved various testing, review procedures and extensive organizational training.
Except as otherwise described above, thereThere have been no significant changes in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of
Aerie Pharmaceuticals, Inc.
In our opinion, the accompanying Consolidated Balance Sheets and the related Consolidated Statements of Operations and Comprehensive Loss, of Stockholders’ Equity (Deficit), and of Cash Flows present fairly, in all material respects, the financial position of Aerie Pharmaceuticals, Inc. and its subsidiaries at December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

AERIE PHARMACEUTICALS, INC.
Notes to the Consolidated Financial Statements
None.
1.    The Company
Aerie Pharmaceuticals, Inc. (“Aerie”), with its wholly-owned subsidiaries Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Limited” and “Aerie Ireland Limited”, respectively, together with Aerie, the “Company”), is a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of small molecule products to treat patients with glaucoma and other diseases of the eye. The Company has its principal executive offices in Irvine, California and operates as one business segment.
The Company has not yet commenced commercial operations and therefore has not generated product revenue. The Company’s activities since inception have primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company does not expect to generate revenue until and unless it receives regulatory approval of and successfully commercializes its product candidates. The Company has incurred losses and experienced negative operating cash flows since inception.
The Company has funded its operations primarily through the sale of equity securities and issuance of convertible notes. In October 2013, the Company completed its initial public offering (“IPO”) and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million. On September 30, 2014, the Company issued $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”). The Company received net proceeds from the issuance of the 2014 Convertible Notes of approximately $122.9 million, after deducting discounts and issuance costs of $2.1 million. Refer to Note 8 for further information regarding the 2014 Convertible Notes.
On November 3, 2014, the Company filed a shelf registration statement on Form S-3 that permits: (i) the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $150.0 million of the Company’s common stock; (ii) sales of common stock by certain selling stockholders; and (iii) the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock that may be issued and sold under an “at-the-market” sales agreement with Cantor Fitzgerald & Co. The common stock that was offered, issued and sold by the Company under this “at-the-market” sales agreement was included in the $150.0 million of common stock that may be offered, issued and sold by the Company under the shelf registration statement. As of December 31, 2015, the Company had no availability to issue shares under this “at-the-market” sales agreement.
On November 6, 2015, the Company filed a prospectus supplement to the base prospectus dated November 10, 2014. The prospectus supplement permits the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock that may be issued and sold by the Company under separate “at-the-market” sales agreements with RBC Capital Markets, LLC and Cantor Fitzgerald & Co. The common stock that may be offered, issued and sold by the Company under these “at-the-market” sales agreements is included in the $150.0 million of common stock that may be offered, issued and sold by the Company under the shelf registration statement. As of December 31, 2015, $48.1 million remained available for issuance under these “at-the-market” sales agreements.
For the year ended December 31, 2015, the Company issued and sold 1,754,556 shares of common stock under the “at-the-market” sales agreements and received net proceeds of $50.5 million, after deducting commissions at a rate of up to 3% of the gross sales price per share sold and other fees and expenses. There were no sales of securities registered pursuant to the shelf registration statement for the year ended December 31, 2014.
In March 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited, a wholly-owned subsidiary organized under the laws of the Cayman Islands. In addition, Aerie assigned the beneficial rights to its non-U.S. and non-Canadian intellectual property to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, Aerie and Aerie Limited entered into a research and development agreement and cost sharing agreement pursuant to which Aerie and Aerie Limited will share the costs of the development of intellectual property. Refer to Note 9 for a description of the tax impact of the IP Assignment. Additionally, in April 2015, the Company continued to prepare for foreign-based activities and established Aerie Ireland Limited as a wholly-owned subsidiary of Aerie Limited to develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment pursuant to a license arrangement to be entered into between Aerie Limited and Aerie Ireland Limited. The Company is currently evaluating the possibility of constructing an Aerie manufacturing plant in Ireland.

F-7



If the Company does not successfully commercialize any of its product candidates, it may be unable to generate product revenue or achieve profitability. Accordingly, the Company may be required to obtain further funding through other public or private offerings, debt financing, collaboration and licensing arrangements or other sources. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs or commercialization efforts.
2.    Significant Accounting Policies
Basis of Presentation
The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Principles of Consolidation
The consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the valuation of stock options and operating expense accruals. Actual results could differ from the Company’s estimates.
Segment Information
Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment.
Reverse Stock Split
The Company effected a 1-for-5 reverse stock split on October 8, 2013. Accordingly, all share and per share amounts for all preceding periods presented in these consolidated financial statements and notes hereto, have been adjusted retroactively to reflect this reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in capital.
CashEquivalents
Cash equivalents consist of short-term, highly liquid investments with an original term of three months or less at the date of purchase. Cash deposits are held by six financial institutions in the United States and two financial institutions in Europe.
Concentration of Credit Risk
The Company’s cash and cash equivalent balances with financial institutions exceed the $250,000 amount insured by the Federal Deposit Insurance Corporation.
Debt Issuance Costs
Debt issuance costs consist of financing costs incurred by the Company in connection with the closing of the 2014 Convertible Notes are included as a direct deduction from the carrying amount of the 2014 Convertible Notes on the Company’s consolidated balance sheets. In connection with the Company’s adoption of ASU 2015-03 in the fourth quarter of 2015, the Company reclassified $1.3 million from Other assets, net to a direct deduction from the carrying amount of the 2014 Convertible Notes on the consolidated balance sheet as of December 31, 2014. Refer to “Recent Accounting Pronouncements” for further information regarding the reclassification. The Company amortizes debt issuance costs through the earlier of maturity or the conversion of the 2014 Convertible Notes using the effective interest method. Refer to Note 8 for further information regarding the 2014 Convertible Notes.
Debt Discounts
Debt discounts consist of fees and expenses incurred by the Company in connection with the closing of the Company’s 2014 Convertible Notes that were paid directly to the note holders. The Company amortizes debt discounts through the earlier of maturity or the conversion of the 2014 Convertible Notes using the effective interest method. Refer to Note 8 for further information regarding the 2014 Convertible Notes.

F-8



Furniture, Fixtures and Equipment, Net
Furniture, fixtures and equipment is recorded at historical cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets. Repairs and maintenance are expensed when incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the determination of net income.
Software Capitalization
The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software including external direct costs of materials and services involved with the software development. Capitalized software costs are included in Furniture, fixtures, and equipment and are amortized over a period of three years beginning when the software project is substantially complete and the asset is ready for its intended use. Costs incurred during the preliminary project stage and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.
Research and Development Costs
Research and development costs are charged to expense as incurred and include, but are not limited to:
Employee-related expenses including salaries, benefits, travel and stock-based compensation expense for research and development personnel;
expenses incurred under agreements with contract research organizations (“CROs”), contract manufacturing organizations and service providers that assist in conducting clinical and preclinical studies;
costs associated with preclinical activities and development activities;
costs associated with regulatory operations; and
depreciation expense for assets used in research and development activities.
Costs for certain development activities, such as clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to the Company by its vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the patterns of costs incurred, and are reflected in the consolidated financial statements as prepaid expenses or accrued expenses as deemed appropriate. No material adjustments to these estimates have been recorded in these consolidated financial statements.
Stock-Based Compensation
Compensation cost of stock-based awards granted to employees is measured at grant date, based on the estimated fair value of the award. The Company estimates the fair value of stock options using a Black-Scholes option pricing model. Compensation cost for options granted to non-employees is determined as the fair value of consideration received or the fair value of the equity instruments issued, whichever is more reliably measured. The fair value of restricted stock awards (“RSAs”) is determined based on the fair value of the Company’s common stock on the date of grant. Stock-based compensation costs are expensed on a straight-line basis (net of estimated forfeitures) over the relevant vesting period. The fair value of unvested awards granted to non-employees is re-measured each period until the related service is complete. Compensation expense for employee stock purchase plan rights (“stock purchase rights”) is measured and recognized on the date that the Company becomes obligated to issue shares of common stock and is based on the difference between the fair value of the Company’s common stock and the purchase price on such date. All stock-based compensation expense is recorded between general and administrative and research and development costs in the consolidated statements of operations based upon the underlying employees roles within the Company. As a result of the taxable gain recognized in connection with the IP Assignment, the Company utilized certain net operating losses, including $462,978 in excess tax benefits related to stock-based compensation, to offset taxable income. In accordance with ASC 718, this excess tax benefit was recorded in additional paid-in capital for the year ended December 31, 2015. No excess tax benefits related to stock-based compensation were recognized for the years ended December 31, 2014 or 2013.
Investments
The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of certificates of deposit, commercial paper, corporate bonds and government agency securities that are classified as available-for-sale in accordance with ASC 320, Investments—Debt and Equity Securities. The Company classifies investments available to fund current operations as current assets on its consolidated balance sheets. Investments are classified as long-term assets on the consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

F-9



Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated other comprehensive gain (loss) on the Company’s consolidated balance sheets. Realized gains and losses are determined using the specific identification method and are included as a component of Other income (expense), net (Note 3). There were no realized gains or losses recognized for the years ended December 31, 2015, 2014 or 2013.
The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers its intent to sell, or whether it is more likely than not that the Company will be required to sell the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, the severity and the duration of the impairment and changes in value subsequent to period end. As of December 31, 2015, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.
Fair Value Measurements
The Company records certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair value of the Company’s financial instruments, including cash and cash equivalents, short-term investments, other current assets, accounts payable and accrued expenses approximate their respective carrying values due to the short-term nature of these instruments. The carrying amounts of long-term investments represent their estimated fair values. The estimated fair value of the 2014 Convertible Notes was $140.1 million and $163.8 million as of December 31, 2015 and 2014, respectively (Note 5). As of December 31, 2015 and 2014, all outstanding warrants are classified as equity and are recorded within additional paid-in capital on the consolidated balance sheets (Note 12).
Stock Purchase Warrants
The Company accounts for its stock purchase warrants as either equity or liabilities based upon the characteristics and provisions of the underlying instruments. Warrants classified as equity are recorded at their fair value on the date of issuance as additional paid-in capital on the consolidated balance sheets and no further adjustments are made to their valuation. Warrants classified as liabilities are recorded at their fair value on the date of issuance and are re-measured on each subsequent balance sheet date until the earlier of the exercise or expiration of the applicable warrants or until such time that the warrants are no longer determined to be derivative instruments. The fair value changes are recognized as income (decreases in fair value) or expense (increases in fair value) in Other income (expense), net in the consolidated statements of operations and comprehensive loss. The fair value of these liabilities is estimated using the Black-Scholes method, which, under the Company’s facts and circumstances, approximates, in all material respects, the values determined when using a Monte Carlo simulation.
Comprehensive Loss
Comprehensive loss is comprised of net loss and other comprehensive loss. Other comprehensive loss includes changes in stockholders’ equity that are excluded from net income (loss), specifically changes in unrealized gains and losses on the Company’s available-for-sale securities.
Income Taxes
Deferred tax assets or liabilities are recorded for temporary differences between financial statement and tax basis of assets and liabilities, using enacted rates in effect for the year in which the differences are expected to reverse. The Company recognizes the impact of an uncertain tax position in the consolidated financial statements only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities. The Company’s policy is to record interest and penalties on uncertain tax positions as income tax expense. The Company did not recognize interest or penalties on uncertain tax positions for the years ended December 31, 2015, 2014 or 2013. As of December 31, 2015 and 2014, the Company had no uncertain tax positions and no interest or penalties were accrued for any uncertain tax positions.
Tax Valuation Allowance
A valuation allowance is recorded if it is more likely than not that a deferred tax asset will not be realized. The Company has provided a full valuation allowance on its deferred tax assets that consist of federal and state net operating losses, stock based compensation and tax credits. Due to the Company’s three year cumulative loss position, history of operating losses and lack of available evidence supporting future taxable income, the Company believes that a valuation allowance on its deferred tax assets as of December 31, 2015 remains appropriate.

F-10



Recent Accounting Pronouncements
In November 2015, the Financial Accounting Standards Board (the “FASB”) issued ASU 2015-17, which requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The guidance is effective for annual periods beginning after December 15, 2016, and all annual and interim periods thereafter, with early adoption permitted. The Company early adopted this guidance for the year ended December 31, 2015. The adoption of this guidance, which was applied retrospectively did not have a material impact on the Company’s consolidated financial statements.
In April 2015, the FASB issued ASU 2015-03, which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt, consistent with the presentation of a debt discount. The guidance is effective for annual periods beginning after December 15, 2015, and all annual and interim periods thereafter. As permitted, the Company early adopted this guidance for the year ended December 31, 2015. The adoption of this guidance, which was applied retrospectively and impacted consolidated balance sheet presentation only, resulted in a reclassification of $1.3 million from Other assets, net to a direct deduction from the carrying amount of the 2014 Convertible Notes on the consolidated balance sheet as of December 31, 2014.
In August 2014, the FASB issued ASU 2014-15, which provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for the Company for the annual period ending after December 15, 2016 and for annual and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements.
Net Loss per Share Attributable to Common Stock
Basic net loss per share attributable to common stock (“Basic EPS”) is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration, and shares that are unequivocally issuable under the Company’s employee stock purchase plan and are therefore included in the calculation of the weighted-average number of shares of common stock as common stock equivalents. Net loss attributable to common stockholders for the year ended December 31, 2013 is calculated by adjusting the Company’s net loss for accretion on convertible preferred stock. Diluted net loss per share attributable to common stock (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss attributable to common stockholders used in calculating Basic EPS is adjusted for certain items related to the dilutive securities.
For all periods presented, the Company’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have the effect of reducing the net loss per share of common stock. Therefore, the denominator used to calculate Basic EPS and Diluted EPS is the same in all periods presented.
The Company’s potential common stock equivalents that have been excluded from the computation of Diluted EPS for all periods presented consist of the following:

5.    Fair Value Measurements
The Company records certain financial assets and liabilities at fair value in accordance with the provisions of ASC Topic 820 on fair value measurements. As defined in the guidance, fair value, defined as an exit price, represents the amount that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, the guidance defines a three-tier value hierarchy that prioritizes the inputs used in the valuation methodologies in measuring fair value.
Level 1—Unadjusted quoted prices in active, accessible markets for identical assets or liabilities.
Level 2—Other inputs that are directly or indirectly observable in the marketplace.
Level 3—Unobservable inputs that are supported by little or no market activity.
The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following tables summarize the fair value of financial assets and liabilities that are measured at fair value and the classification by level of input within the fair value hierarchy:

As of December 31, 2015 and 2014, the estimated fair value of the 2014 Convertible Notes was $140.1 million and $163.8 million, respectively. The estimated fair value of the 2014 Convertible Notes was determined using a scenario analysis and Monte Carlo simulation model to capture the various features of the 2014 Convertible Notes. The scenario analysis and Monte Carlo simulation require the use of Level 3 unobservable inputs and subjective assumptions, including but not limited to the probability of conversion, stock price volatility, the risk free interest rate and credit spread. The decrease in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the change in the closing price of Aerie’s common stock on December 31, 2015 as compared to December 31, 2014. The estimates presented are not necessarily indicative of amounts that could be realized in a current market exchange. The use of alternative market assumptions and estimation methodologies could have a material effect on these estimates of fair value.

8.    Convertible Notes
On September 30, 2014, Aerie issued the 2014 Convertible Notes to Deerfield Partners, L.P., Deerfield International Master Fund, L.P., Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. and Deerfield Special Situations International Master Fund, L.P. (collectively, “Deerfield”). On January 1, 2015, Deerfield Special Situations International Master Fund, L.P. transferred all of its rights under the 2014 Convertible Notes to Deerfield Special Situations Fund, L.P.
The 2014 Convertible Notes bear interest at a rate of 1.75% per annum payable quarterly in arrears on the first business day of each January, April, July and October. The 2014 Convertible Notes mature on the seventh anniversary from the date of issuance, unless earlier converted.
The 2014 Convertible Notes constitute a senior secured obligation of Aerie, collateralized by a first priority security interest in substantially all of the assets of Aerie. The 2014 Convertible Notes provide that, upon the request of Aerie, Deerfield will release all of the liens on the collateral if both of the following occur: (i) beginning one month after FDA approval of either RhopressaTM or RoclatanTM, shares of Aerie’s common stock have traded at a price above $30 per share (subject to adjustment for any subdivision or combination of outstanding common stock) for 30 consecutive trading days, and (ii) Aerie is prepared to

F-15



close a financing that will be secured by a lien on Aerie’s assets, subject only to the release of the lien on Aerie’s assets held by Deerfield.
In connection with the IP Assignment, Aerie granted Deerfield a security interest in an intercompany promissory note and pledged 65% of the voting stock of Aerie Limited. Upon the request of Aerie, Deerfield will release the lien on the intercompany promissory note under certain circumstances.
At closing, Aerie paid Deerfield a one-time transaction fee of $625,000. In addition, Aerie reimbursed Deerfield in the amount of $250,000 for certain expenses incurred by Deerfield in connection with the transaction. Aerie also incurred $1.3 million of legal and advisory fees in connection with the transaction.
The 2014 Convertible Notes are convertible at any time at the option of Deerfield, in whole or in part, into shares of common stock, including upon the repayment of the 2014 Convertible Notes at maturity (the “Conversion Option”). However, upon conversion, Deerfield (together with their affiliates) is limited to a 9.985% ownership cap in shares of common stock (the “9.985% Cap”). The 9.985% Cap would remain in place upon any assignment of the 2014 Convertible Notes by Deerfield.
The initial conversion price is $24.80 per share of common stock (equivalent to an initial conversion rate of 40.32 shares of common stock per $1,000 principal amount of 2014 Convertible Notes), representing a 30% premium over the closing price of the common stock on September 8, 2014. The conversion rate and the corresponding conversion price are subject to adjustment for stock dividends (other than a dividend for which Deerfield would be entitled to participate on an as-converted basis), stock splits, reverse stock splits and reclassifications. In addition, in connection with certain significant corporate transactions, Deerfield, at its option, may (i) require Aerie to prepay all or a portion of the principal amount of the 2014 Convertible Notes, plus accrued and unpaid interest, or (ii) convert all or a portion of the principal amount of the 2014 Convertible Notes into, depending upon the type of transaction, shares of common stock or the right to receive upon consummation of the transaction the consideration Deerfield would have received had Deerfield converted the 2014 Convertible Notes immediately prior to the consummation of the transaction. The 2014 Convertible Notes provide for an increase in the conversion rate if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction. The current maximum increase to the initial conversion rate, in connection with a significant corporate transaction, is 12.07 shares of common stock per $1,000 principal amount of 2014 Conversion Notes, which decreases over time and is determined by reference to the price of the common stock prior to the consummation of the significant corporate transaction or the value of the significant corporate transaction.
The agreement governing the 2014 Convertible Notes contains various representations and warranties, and affirmative and negative covenants, customary for financings of this type, including restrictions on the incurrence of additional debt and liens on Aerie’s assets. As of December 31, 2015, Aerie was in compliance with the covenants. The agreement governing the 2014 Convertible Notes also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie; the suspension, cancellation or revocation of governmental authorizations that are reasonably expected to have a material adverse effect on Aerie’s business; the acceleration of a specified amount of indebtedness; and the failure to deliver shares of common stock upon conversion of the 2014 Convertible Notes. If any event of default were to occur, and continue beyond any applicable cure period, the holders of more than 50% of the aggregate principal amount of the then outstanding 2014 Convertible Notes would be permitted to declare the principal and accrued and unpaid interest to be immediately due and payable.
The Company recorded the 2014 Convertible Notes as long-term debt at face value less debt discounts relating to fees and certain expenses paid to Deerfield in connection with the transaction. The Conversion Option is a derivative that qualifies for an exemption from bifurcation and liability accounting as provided for in ASC Topic 815, Derivatives and Hedging – Contracts in Entity’s Own Equity (“ASC 815”). Since the Conversion Option is not bifurcated as a derivative pursuant to ASC 815, the Company further evaluated the Conversion Option to determine whether it is considered a beneficial conversion feature (“BCF”). The Company determined that the initial accounting conversion price was greater than the fair value of the common stock at the close of trading on the date of issuance, therefore no BCF existed at inception. However, if Deerfield elects to convert their 2014 Convertible Notes in connection with a significant corporate transaction, the increase to the initial conversion rate may cause a contingent BCF to exist at the time of conversion. The contingent BCF, if any, will be recognized in earnings when the contingency is resolved and will be measured using the fair value of the common stock at the close of trading on the date of issuance and the accounting conversion price as adjusted for such an increase to the initial conversion rate.
As of December 31, 2015, the Company recognized unamortized debt discounts and debt issuance costs of $1.8 million. Debt discounts and debt issuance costs are amortized using the effective interest method through the earlier of maturity or the conversion of the 2014 Convertible Notes.

For the years ended December 31, 2015 and 2014, interest expense related to the 2014 Convertible Notes was $2.2 million and $551,000, respectively.
On December 7, 2012, the Company authorized the sale of convertible notes (the “2012 Notes”) to related parties in the aggregate principal amount of $15.0 million. The 2012 Notes accrued interest at a rate of 8% per annum, with principal plus accrued interest thereon due upon maturity at September 30, 2013. The initial closing comprised of five individual convertible notes with an aggregate principal balance of $3.0 million. As of December 31, 2012, $12.0 million of 2012 Notes were authorized and available for sale. On March 28, 2013, May 23, 2013 and August 9, 2013, the Company completed the second, third and fourth closing of the 2012 Notes, respectively. The closings each comprised of five individual convertible notes with aggregate principal balances of $3.0 million, $4.5 million, and $4.5 million, respectively. On August 9, 2013, the Company amended the agreements relating to the 2012 Notes. The amendment authorized the sale of an additional $3.0 million of the 2012 Notes, resulting in an aggregate principal amount of $18.0 million being authorized. In addition, the amendment extended the maturity date of the 2012 Notes from September 30, 2013 to December 31, 2013 and the issuance period through November 30, 2013. No other terms and conditions of the agreements were changed as part of the amendment. In accordance with ASC 470 Debt, the amendment met the criteria of a troubled debt restructuring and the amortization of the debt discount was revised to align with a new effective interest rate determined as of the amendment date. No gain was recorded as part of the restructuring. On September 30, 2013, the Company completed the fifth closing of the 2012 Notes. Aggregate proceeds to the Company were $3.0 million.
On October 30, 2013, upon closing of the IPO, the principal and accrued interest outstanding under the 2012 Notes were converted into 1,860,363 shares of common stock at a conversion price equal to the IPO price of $10.00 per share. The Company accounted for the conversion as an extinguishment of debt.
In connection with the issuance of the 2012 Notes, the Company determined that a certain conversion feature was an embedded derivative requiring bifurcation and separate accounting. To estimate the fair value, the Company compared the net present value of expected cash flows of the issued 2012 Notes with and without the conversion feature comprising the embedded derivative. The Company determined that the fair value of the embedded derivative was immaterial as of August 9, 2013, May 23, 2013, March 28, 2013 and December 7, 2012, representing the fourth, third, second and initial closing dates, and as of December 31, 2012. As of September 30, 2013, the fair value of the embedded derivative was $96,000 . The Company determined that upon the closing of the IPO on October 30, 2013, at which time the 2012 Notes were converted into common stock, no embedded derivative existed. The Company recorded the change in fair value as a component of Other income (expense), net.

In January 2015, the Company participated in the New Jersey Economic Development Authority’s Sponsored Technology Business Tax Certificate Transfer Program to transfer $3.1 million in state tax benefits to unrelated profitable businesses with operations in the state of New Jersey. The Company received net proceeds of $2.9 million from the transfer.
The IP Assignment resulted in the recognition of a taxable gain for U.S. federal and state income tax purposes. As of December 31, 2015, the estimated income tax liability was $1.7 million after utilization of net operating loss carry-forwards, current year losses generated through December 31, 2015 and quarterly estimated payments made through December 31, 2015. Under ASC 810, Consolidation, the income tax expense of $2.8 million for the year ended December 31, 2015 was recorded as a prepaid asset. In accordance with ASC 810, Consolidation, the estimated prepaid asset will be amortized into income tax expense over the estimated remaining patent life of the intellectual property subject to the IP Assignment, through approximately 2030. For the year ended December 31, 2015, the Company recognized $139,000 of income tax expense related to the amortization of the prepaid asset.
Largely as a result of the IP Assignment, the Company reversed approximately $29.5 million of its valuation allowance on certain deferred tax assets, primarily federal and state net operating losses, as of December 31, 2015. Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carry-forward period. Due to the Company’s history of operating losses and lack of available evidence supporting future taxable income, the Company believes that a valuation allowance on its remaining deferred tax assets as of December 31, 2015 remains appropriate.
In addition, the IP Assignment is subject to complex tax and transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with the Company’s determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and the Company’s position were not sustained, the Company could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates and reduced cash flows than otherwise would be expected.
It is Aerie’s intention to reinvest the earnings of Aerie Limited and Aerie Ireland Limited in those operations. Generally, such amounts become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. Aerie Limited and Aerie Ireland Limited have incurred losses and experienced negative operating cash flows since inception, and as such, Aerie has not recognized a deferred tax liability related to its investment in either subsidiary as of December 31, 2015.
As of December 31, 2015, the Company had federal and state net operating loss carry-forwards of approximately $61.1 million, which expire from 2024 through 2034. Included in the net operating loss carry-forwards are approximately $4.0 million of net operating loss carry-forwards related to exercises of stock-based awards, the tax benefit from which, if realized, will be credited to additional paid-in capital. Net operating loss and tax credit carry-forwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities and may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities.
Certain transactions occurred in 2015 and prior years that resulted in ownership changes which will limit the future use of certain federal and state net operating loss and credit carry-forwards. Those federal and state net operating losses and credits that are not limited are included as deferred tax assets and have been fully offset by a valuation allowance as of December 31, 2015, as the Company believes, based on our history of operating losses, it is more likely than not that the tax benefits will not be realized.

10.    Convertible Preferred Stock
On October 30, 2013, immediately prior to the closing of the Company’s IPO, all outstanding shares of convertible preferred stock automatically were converted into an aggregate of 12,120,531 shares of common stock. As of December 31, 2015 and December 31, 2014, no convertible preferred stock was authorized, issued or outstanding.
Carrying Value
On February 23, 2011, the Company received $23.8 million in proceeds from the issuance of its Series B Convertible Preferred Stock, net of $1.2 million of transaction costs. The convertible preferred stock was originally recorded at the net proceeds received by the Company at issuance. The difference between the net proceeds and the total redemption price was being accreted on a straight-line basis over the period from issuance until the earliest redemption date and was accreted to the convertible preferred stock capital account through the completion of the IPO. Accretion amounted to $210,000 for the year ended December 31, 2013.
On February 23, 2011, the Company issued the Series A-4 Convertible Preferred Stock in connection with the conversion of a series of convertible notes. The issuance was recorded at fair value. The difference between stated and fair value of $1.3 million was being accreted on a straight-line basis of the period from February 23, 2011 until the earliest redemption date and was accreted to the Series A-4 Convertible Preferred Stock capital account through the completion of the IPO. Accretion amounted to $240,000 for the year ended December 31, 2013. The Company determined that the straight-line method approximated the effective interest method. 
11.     Stockholders’ Equity (Deficit)
On October 30, 2013, the Company completed its IPO and issued 7,728,000 shares of its common stock at an IPO price of $10.00 per share, including 1,008,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares to cover over-allotments. The shares began trading on the NASDAQ Global Market on October 25, 2013. The Company received net proceeds from the IPO of approximately $68.3 million, after deducting underwriting discounts and commissions of $5.4 million and expenses of $3.6 million.
In connection with the IPO, the following events occurred:
On October 24, 2013, 297,366 warrants to purchase convertible preferred stock were net exercised and were subsequently automatically converted into 297,366 shares of common stock on October 30, 2013 (Note 12);
On October 30, 2013, 186,248 warrants to purchase convertible preferred stock were net exercised and were subsequently automatically converted into 186,248 shares of common stock on October 30, 2013 (Note 12);
On October 30, 2013, the outstanding shares of convertible preferred stock were automatically converted into an aggregate 12,120,531 shares of common stock (Note 10);
On October 30, 2013, 717,801 warrants to purchase convertible preferred stock were automatically converted into 717,801 warrants to purchase common stock, at which time the liabilities were re-measured and reclassified to equity (Note 12);
On October 30, 2013, the principal and interest outstanding under the 2012 Notes were converted into 1,860,363 shares of common stock at a conversion price equal to the IPO price of $10.00 per share (Note 8);
On October 30, 2013, the 2013 Omnibus Incentive Plan became effective under which 3,229,068 equity awards for common stock of the Company may be distributed (Note 13); and

 August 2020 Common Stock
223,482 $0.05
 December 2019 Common Stock
The warrants outstanding at December 31, 2015 are all currently exercisable with weighted-average remaining lives of 3.8 years.
Prior to the IPO, the Company recognized all of its outstanding warrants as liabilities on its consolidated balance sheet as they were subject to price protection provisions. The warrant liability was revalued at each reporting period and changes in fair value were included as a component of Other income (expense), net. For the year ended December 31, 2013, the Company recognized $3.7 million of expense related to changes in the fair value of the warrant liability. The initial recognition and subsequent changes in fair value of the warrant liability had no effect on the Company’s consolidated statement of cash flows.
The Company estimated the fair value of the warrants using the Black-Scholes option-pricing model utilizing the fair value of underlying preferred and common stock. Black-Scholes has inherent limitations for use in the case of a warrant with a price protection provision, since the model is designed to be used when the inputs to the model are static throughout the life of a security. Management concluded, under the Company’s facts and circumstances, that the estimated fair values of the warrants using the Black-Scholes option-pricing model approximates, in all material respects, the values determined using a Monte Carlo valuation model. The estimates in the Black-Scholes option-pricing model and the Monte Carlo valuation model are based, in part, on assumptions, including but not limited to stock price volatility, the expected life of the warrants, the risk free rate and the fair value of the equity stock underlying the warrants.
Key assumptions utilized in the fair value calculation as of October 30, 2013, the IPO closing date, appear in the table below.

13.     Stock-based Compensation
Stock-based compensation expense for options granted, RSAs, and stock purchase rights are reflected in the statement of operations as follows:
 YEAR ENDED DECEMBER 31,
(in thousands)2015 2014 2013

 $222
General and administrative10,445
 7,839
 2,636
Total$12,945
 $9,178
 $2,858
The estimated fair value of options granted is determined on the date of grant using the Black-Scholes option pricing model. Options granted to non-employees are revalued at each financial reporting period until required service is performed. Compensation expense related to RSAs is based on the market value of the Company’s common stock on the date of grant and is expensed on a straight-line basis over the vesting period. Compensation expense for stock purchase rights under the Company’s employee stock purchase plan is measured and recognized on the date that the Company becomes obligated to issue shares of common stock and is based on the difference between the fair value of the Company’s common stock and the purchase price on such date.

As of December 31, 2015, the Company had $28.2 million of unrecognized compensation expense related to options granted under its equity plans. This cost is expected to be recognized over a weighted average period of 2.6 years as of December 31, 2015. The weighted average remaining contractual life on all outstanding options as of December 31, 2015 was 8.0 years.
As of December 31, 2015, the Company had $1.7 million of unrecognized compensation expense, related to unvested RSAs. This cost is expected to be recognized over a weighted average period of 2.9 years as of December 31, 2015. The weighted average remaining contractual term for restricted stock awards as of December 31, 2015 was 2.9 years.
Key weighted average assumptions utilized in the fair value calculation for the underlying common stock as of December 31, 2015, 2014 and 2013 appear on the table below.

Risk-free interest rate1.63% 1.90% 1.78%
Dividend yield% % %

Based on the Company’s historical experience of employee turnover, an annualized forfeiture rate was assumed for options and RSAs. Under the true-up provisions of the stock compensation guidance, additional expense is recognized as the awards vest if the actual forfeiture rate is lower than estimated, and a recovery of prior expense if the actual forfeiture is higher than estimated.
The Company utilized the guidance set forth in the SEC Staff Accounting Bulletin 107, Share-Based Payment (“SAB 107”), to determine the expected term of options, as it does not have sufficient historical exercise and post vesting termination data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The midpoint between the vesting date and the maximum contractual expiration date is used as the expected term under this method.
The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected time to liquidity.
Volatility is based on the historical volatility of the Company as well as several public entities that are similar to the Company. This peer group of companies utilized in 2015 remained consistent with that of 2014.

F-22



Equity Plans
The Company maintains two equity compensation plans, the 2005 Aerie Pharmaceutical Stock Plan (the “2005 Plan”) and the 2013 Omnibus Incentive Plan (the “2013 Equity Plan”), which was amended and restated as the Aerie Pharmaceuticals, Inc. Amended and Restated Omnibus Incentive Plan (the “Amended and Restated Equity Plan”). The 2005 Plan and the Amended and Restated Equity Plan are referred to collectively as the “Plans.”
On October 30, 2013, the effective date of the 2013 Equity Plan, the 2005 Plan was frozen and no additional awards have been or will be made under the 2005 Plan. Any shares remaining available for future grant under the 2005 Plan were allocated to the 2013 Equity Plan.
At the 2015 Annual Meeting of Stockholders held on April 10, 2015, the Company’s stockholders approved the adoption of the Amended and Restated Equity Plan and no additional awards have been or will be made under the 2013 Equity Plan. Any remaining shares available under the 2013 Equity Plan were allocated to the Amended and Restated Equity Plan.
The Amended and Restated Equity Plan provides for the granting of up to 5,729,068 equity awards in respect of common stock of the Company, including equity awards that were available for issuance under the 2013 Equity Plan.

Litigation
The Company may periodically become subject to legal proceedings and claims arising in connection with its business. Except as set forth below, the Company is not a party to any known litigation, is not aware of any unasserted claims and does not have contingency reserves established for any litigation liabilities.
 A putative securities class action lawsuit captioned Kelley et al. v. Aerie Pharmaceuticals, Inc., et al., Case No. 3:15-cv-03007, was filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey on April 29, 2015. An amended complaint was filed on September 28, 2015 on behalf of a purported class of persons and entities who purchased or otherwise acquired the Company’s publicly traded securities between June 25, 2014 and April 23, 2015. The amended complaint asserts claims under the Exchange Act and alleges that the defendants made materially false and misleading statements or omitted allegedly material information during that period related to, among other things, the prospects of the Company’s initial Phase 3 registration trial of RhopressaTM, named “Rocket 1,” and RhopressaTM.
The Company believes that the claims asserted in the action are without merit and intends to defend the lawsuit vigorously, and the Company expects to incur costs associated with defending the action. In addition, the Company has various insurance policies related to the risks associated with its business, including directors’ and officers’ liability insurance policies. However, there is no assurance that the Company will be successful in its defense of the action, and there is no assurance that the Company’s insurance coverage, which contains a self-insured retention, will be sufficient or that its insurance carriers will cover all claims or litigation costs. At this time, the Company cannot accurately predict the ultimate outcome of this matter.

F-24



Due to the inherent uncertainties of litigation, the Company cannot reasonably predict the timing or outcomes, or estimate the amount of loss, or range of loss, if any, or their effect, if any, on the Company’s financial statements.
Contract Service Providers
In the course of the Company’s normal business operations, it has agreements with contract service providers to assist in the performance of its research and development, clinical research and manufacturing and other general business activities. Substantially all of these contracts are on an as needed basis. Future minimum commitments of the Company due under non-cancelable agreements with service providers was $620,000 as of December 31, 2015 and are expected to be incurred by December 2017.
15.    Related-Party Transactions
Collaboration
In August 2015, the Company entered into a research collaboration and license agreement with GrayBug, Inc. (“GrayBug”). The collaboration is focused on researching the potential use of Graybug’s biodegradable polymer technology to deliver certain of the Company’s preclinical stage molecules to the back of the eye over a sustained period of time. The Board of Directors of the Company and that of GrayBug have a common Board member. This Board member did not participate in any deliberations associated with this transaction.
2012 Notes
Prior to their conversion into common stock in connection with the IPO (Note 8), the 2012 Notes were due to holders of the Company’s convertible preferred stock. Interest expense on those obligations was $588,000 for the year ended December 31, 2013.
Consultation
For the years ended December 31, 2015, 2014 and 2013, the respective amounts of approximately $240,000, $333,000 and $190,000 were paid to board members, some of whom served as consultants of the Company through consulting agreements containing arm’s-length terms typical of agreements entered into with unaffiliated third parties.
16.    Benefit Plans
Defined Contribution Plans
Aerie has adopted a 401(k) deferred compensation plan. Eligible employees meeting the participant criteria may contribute up to the statutory limitation ($18,000 for 2015 and $17,500 for 2014). Aerie may contribute a discretionary match if it elects to do so. During the years ended December 31, 2015, 2014 and 2013, Aerie contributed $0 as a matching contribution to the plan.
In October 2015, Aerie Ireland Limited adopted the Aerie Pharmaceuticals Ireland Pension and Life Assurance Scheme. Eligible employees meeting the participation criteria may contribute up to the aggregate statutory limitation of 15% to 40% of remuneration depending on age. During the year ended December 31, 2015, Aerie Ireland Limited contributed $0 as a matching contribution to the plan.
Employee Stock Purchase Plan
On October 30, 2013, the Company adopted the 2013 Employee Stock Purchase Plan (the “Purchase Plan”) under which substantially all employees may purchase the Company’s common stock through payroll deductions and lump sum contributions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of the offering periods. Employees may not purchase more than the fair value equivalent of $25,000 of stock during any calendar year. As of December 31, 2015, approximately 629,844 shares were reserved for future issuance under the Purchase Plan.
17.    Subsequent Events
On February 24, 2016, the Board of Directors authorized grants of common stock options and restricted stock awards to the officers of the Company in the aggregate amount of 332,754 and 55,960, respectively. The options have an exercise price of $16.69 per share, a term of ten years and are subject to vesting conditions over a four-year period. The aggregate fair value of these option grants was approximately $3.8 million. The restricted stock awards are subject to vesting conditions over a four-year period. The aggregate fair value of these restricted stock awards was approximately $0.9 million.

We have audited the accompanying consolidated balance sheets of Aerie Pharmaceuticals, Inc. and its subsidiaries (the “Company”) as of December 31, 2018 and 2017, and the related consolidated statements of operations and comprehensive loss, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

AERIE PHARMACEUTICALS, INC.
Notes to the Consolidated Financial Statements
1.    The Company
Aerie Pharmaceuticals, Inc. (“Aerie”), with its wholly-owned subsidiaries, Aerie Distribution, Inc., Aerie Pharmaceuticals Limited and Aerie Pharmaceuticals Ireland Limited (“Aerie Distribution,” “Aerie Limited” and “Aerie Ireland Limited,” respectively, together with Aerie, the “Company”), is an ophthalmic pharmaceutical company focused on the discovery, development and commercialization of first-in-class therapies for the treatment of patients with open-angle glaucoma, retinal diseases and other diseases of the eye. The Company has its principal executive offices in Durham, North Carolina, and operates as one business segment.
The Company has a U.S. Food and Drug Administration (“FDA”) approved product, Rhopressa®(netarsudil ophthalmic solution) 0.02% (“Rhopressa®”), and an advanced-stage product candidate, RocklatanTM(netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% (“RocklatanTM”), previously referred to as RoclatanTM, both designed to reduce elevated intraocular pressure (“IOP”) in patients with open-angle glaucoma or ocular hypertension. The Company is commercializing Rhopressa® and intends to commercialize RocklatanTM, if approved, on its own in North American markets. The Company’s strategy also includes pursuing regulatory approval for Rhopressa® and RocklatanTM in Europe and Japan on its own, though the products may be named differently in those respective regions.
Rhopressa® is a once-daily eye drop designed to reduce elevated IOP in patients with open-angle glaucoma or ocular hypertension that received FDA approval on December 18, 2017. The Company launched Rhopressa® in the United States at the end of April 2018. On October 9, 2018, the Company announced that the European Medicines Agency (“EMA”) accepted for review the marketing authorization application (“MAA”) for Rhopressa®, which will be marketed under the name Rhokiinsa® in Europe, if approved. Additionally, the Company has completed a Phase 1 clinical trial and a successful pilot Phase 2 clinical study in the United States on Japanese and Japanese-American subjects, which were designed to support meeting the requirements of Japan’s Pharmaceuticals and Medical Devices Agency for potential regulatory submission of Rhopressa® in Japan. The Company is also planning to initiate a Phase 2 clinical trial on Japanese patients in Japan by the end of the first quarter of 2019 to support subsequent Phase 3 registration trials that are also expected to be conducted in Japan under its direction.
The Company’s advanced-stage product candidate, RocklatanTM, is a once-daily fixed-dose combination of Rhopressa® and latanoprost. The Company submitted a New Drug Application (“NDA”) to the FDA in May 2018. In July 2018, the Company announced that the NDA was accepted for review by the FDA and the Prescription Drug User Fee Act goal date was set for March 14, 2019, which represents a ten-month review. In Europe, the Company is currently conducting a Phase 3 trial, named Mercury 3, comparing RocklatanTM to Ganfort®, a fixed-dose combination product marketed in Europe of bimatoprost (a prostaglandin analog) and timolol (a beta blocker). If successful, Mercury 3 is expected to improve its commercialization prospects in Europe. Mercury 3 is not necessary for approval in the United States. The Company plans to submit an MAA with the EMA in early 2020 for RocklatanTM, if the EMA has approved Rhokiinsa® by such time. RocklatanTM will be marketed under the name RoclandaTM in Europe, if approved.
The Company is also focused on furthering the development of its preclinical molecules and technologies focused on retinal diseases, particularly AR-13503 and AR-1105. Through business development activities, discussed further below, the Company has acquired worldwide ophthalmic rights to a bio-erodible polymer technology from DSM, a global science-based company headquartered in the Netherlands, and PRINT® implant manufacturing technology from Envisia Therapeutics Inc. (“Envisia”), with which the Company has created a sustained-release ophthalmology platform. Using this technology, the Company is currently developing two preclinical sustained-release implants, AR-13503 and AR-1105, both of which are expected to commence clinical trials in 2019.
In July 2017, the Company entered into a collaborative research, development and licensing agreement with DSM, which included an option to license DSM’s bio-erodible polymer implant technology for sustained delivery of certain Aerie compounds to treat ophthalmic diseases. This technology uses polyesteramide polymers to produce an injectable, thin fiber that is minute in size.
On August 1, 2018, the Company entered into an Amended and Restated Collaborative Research, Development, and License Agreement with DSM (the “Collaboration Agreement”), which provides for (i) a worldwide exclusive license for all ophthalmic indications to DSM’s polyesteramide polymer technology, (ii) continuation of the collaborative research initiatives through the end of 2020, including the transfer of DSM’s formulation technology to Aerie during that time and (iii) access to a


preclinical latanoprost implant. Aerie paid $6.0 million to DSM upon execution of the Collaboration Agreement, with an additional $9.0 million payable to DSM through the end of 2020. As a result, $9.6 million related to the expanded collaboration agreement with DSM was expensed to research and development expense during the year ended December 31, 2018, which included the upfront payment of $6.0 million. The Collaboration Agreement includes contingent payments of up to $75.0 million that may be due to DSM upon the achievement of certain development and regulatory milestones. In addition, pursuant to the Collaboration Agreement, a $3.0 million milestone payment was made during the year ended December 31, 2018 upon the completion of certain manufacturing technology transfer activities. Aerie would also pay royalties to DSM when products are commercialized under this Collaboration Agreement, if any.
In October 2017, the Company entered into an Asset Purchase Agreement (the “Agreement”) with Envisia to acquire the rights to use PRINT® technology in ophthalmology, as well as rights relating to a preclinical dexamethasone steroid implant for the potential treatment of retinal vein occlusion and diabetic macular edema that utilizes the PRINT® technology, referred to as AR-1105. Under the terms of the Agreement, the Company (a) made an upfront cash payment of $10.5 million and issued 263,146 shares of Aerie’s common stock valued at approximately $14.3 million and (b) agreed to make potential milestone payments of up to an aggregate of $45.0 million, contingent upon the achievement of certain product regulatory approvals. Under the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805: Business Combinations (“ASC Topic 805”), including the provisions of Accounting Standards Update (“ASU”) 2017-01 (see Note 2), the Company accounted for the transaction as an asset acquisition rather than a business combination, and expensed $24.8 million of acquired in-process research and development (“IPR&D”) to research and development in the consolidated statement of operations and comprehensive loss during the three months ended December 31, 2017. In addition, any milestone payments will be recognized only once the contingency is resolved and such amounts are payable.
The Company launched Rhopressa® in the United States in April 2018 and commenced generating product revenues in the second quarter of 2018. The Company’s activities prior to the commercial launch of Rhopressa® had primarily consisted of developing product candidates, raising capital and performing research and development activities. The Company has incurred losses and experienced negative operating cash flows since inception. The Company had previously funded its operations primarily through the sale of equity securities (Note 11) and issuance of convertible notes (Note 9) prior to generating product revenues.
If the Company does not successfully commercialize Rhopressa®, RocklatanTM or any future product candidates, it may be unable to achieve profitability. Accordingly, the Company may be required to draw down on the $100 million senior secured delayed draw term loan facility (the “credit facility”) that was entered into in July 2018, or to obtain further funding through public or private debt or equity offerings, or other arrangements. Adequate additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on acceptable terms, it may be forced to delay, reduce or eliminate its research and development programs or commercialization and manufacturing efforts.
2.    Significant Accounting Policies
Basis of Presentation and Consolidation
The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation. Certain reclassifications have been made to prior year amounts to conform to the current year presentation.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include revenue recognition, inventories, accrued expenses, fair value measurements, acquisitions and stock-based compensation. Actual results could differ from the Company’s estimates.
Segment Information
Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business as one operating segment.

Concentration of Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and investments. The Company’s cash and cash equivalents, which include short-term highly liquid investments with original maturities of three months or less, are held at several financial institutions and at times may exceed insured limits. The Company has placed these funds in high quality institutions to minimize risk relating to exceeding insured limits. The Company’s investment policy permits investments in U.S. federal government and federal agency securities, corporate bonds or commercial paper, money market instruments, and certain qualifying money market mutual funds, and places restrictions on credit ratings, maturities, and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash, cash equivalents and investments to the extent recorded on the consolidated balance sheet.
The Company relies on its third-party manufacturers to produce the active pharmaceutical ingredient (“API”) and final drug product for Rhopressa® and RocklatanTM and may rely on third-party manufacturers for its current and future product candidates. The Company is in the process of adding an additional API contract manufacturer and an additional Rhopressa® drug product contract manufacturer, both of which are expected to begin to supply commercial materials in the first half of 2019. In addition, the Company is in the process of establishing its own manufacturing plant in Athlone, Ireland, for future commercial production of Rhopressa® and, if approved, RocklatanTM,Rhokiinsa® and RoclandaTM. Commercial supply from the plant is expected to be available in early 2020.
CashEquivalents
The Company’s cash and cash equivalents are held principally at several financial institutions and at times may exceed insured limits. The Company has placed these funds in high quality institutions in order to minimize risk relating to exceeding insured limits.
Inventories
Prior to the date the Company obtains regulatory approval for its product candidates, manufacturing costs related to commercial production are expensed as pre-approval commercial manufacturing expense. Once regulatory approval is obtained, the Company capitalizes such costs as inventory. Inventories are stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels at least quarterly and writes down inventory that is expected to expire prior to being sold, inventory in excess of expected sales requirements and inventory that fails to meet commercial sale specifications, with a corresponding charge to cost of goods sold. The determination of whether inventory costs will be realizable requires estimates by management of future expected inventory requirements based on sales forecasts. If actual net realizable value is less than the estimated amount or if actual market conditions are less favorable than the Company’s projections, additional inventory write-downs may be required. Charges for inventory write-downs are not reversed if it is later determined that the product is saleable.
Property, Plant and Equipment, Net
Property, plant and equipment is recorded at historical cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets. Construction-in-progress reflects amounts incurred for property, plant or equipment construction or improvements that have not been yet placed in service and are not depreciated or amortized, which primarily relates to the build-out of the Company’s manufacturing plant in Ireland. Repairs and maintenance are expensed when incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the determination of net loss.

Estimated useful lives by major asset category are as follows:
Manufacturing equipment10 years
Laboratory equipment7 years
Furniture and fixtures5 years
Software, computer and other equipment3 years
Leasehold improvementsLower of estimated useful life or term of lease
Impairment of Long-Lived Assets
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. For the years ended December 31, 2018, 2017 and 2016, no such impairment losses have been recorded by the Company.
Acquisitions
The Company evaluates acquisitions to determine whether the acquisition is a business combination or an acquisition of assets under ASC Topic 805. Business combinations are accounted for using the acquisition method of accounting, whereby assets acquired and liabilities assumed are recorded as of the acquisition date at their respective fair values and excess of the fair value of the consideration transferred over the fair value of the net assets acquired is recorded as goodwill. In an asset acquisition that does not constitute a business, no goodwill is recognized, and the net assets acquired are generally recorded at cost. Significant judgment is required in estimating the fair value of intangible assets and in a determination of whether an acquisition is a business combination or an acquisition of assets. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management, but are inherently uncertain.
The consolidated financial statements as of and for the year ended December 31, 2017 include the impact of the acquisition of assets from Envisia (see Note 1 for additional information).
Revenue Recognition
Effective January 1, 2018, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”). The Company did not generate any revenue prior to the three months ended June 30, 2018, and therefore the adoption of ASC Topic 606 did not have an impact on the Company’s financial statements for any prior periods or upon adoption. In accordance with ASC Topic 606, the Company recognizes revenue when the customer obtains control of a promised good or service, in an amount that reflects the consideration that the Company expects to receive in exchange for the good or service. The reported results for the year ended December 31, 2018 reflect the application of ASC Topic 606.
The Company’s net product revenues are generated through sales of Rhopressa®, which was approved by the FDA in December 2017 and was commercially launched in the United States on April 30, 2018. See Note 3 for additional information.
Research and Development Costs
Research and development costs are charged to expense as incurred and include, but are not limited to: 
employee-related expenses including salaries, benefits, travel and stock-based compensation expense for research and development personnel;
expenses incurred under agreements with contract research organizations (“CROs”), contract manufacturing organizations and service providers that assist in conducting clinical and preclinical studies;
costs associated with any collaboration arrangements, licenses or acquisitions of preclinical molecules, product candidates or technologies;
costs associated with preclinical activities and development activities;
costs associated with regulatory operations; and

depreciation expense for assets used in research and development activities.
Costs for certain development activities, such as clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to the Company by its vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the patterns of costs incurred, and are reflected in the consolidated financial statements as prepaid expenses or accrued expenses as deemed appropriate. No material adjustments to these estimates have been recorded in these consolidated financial statements.
Research and development costs also include the cost of IPR&D projects acquired as part of an asset acquisition that have no alternative future use. Milestone payments due to third parties in connection with research and development activities prior to regulatory approval are expensed as incurred, while milestone payments due to third parties upon, or subsequent to, regulatory approval are capitalized and amortized over the estimate useful life.
Stock-Based Compensation
Stock-based compensation for awards granted to employees and non-employees is measured at grant date, based on the estimated fair value of the award. The Company estimates the fair value of options to purchase common stock and stock appreciation rights (“SARs”) using a Black-Scholes option pricing model. The Black-Scholes option pricing model utilizes assumptions including expected term, volatility, a risk-free interest rate and an expected dividend yield. The Company utilized the guidance set forth in the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin 107, Share-Based Payment (“SAB 107”), to determine the expected term of options, as it does not have sufficient historical exercise and post-vesting termination data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The simplified method utilizes the midpoint between the vesting date and the maximum contractual expiration date as the expected term. Volatility is based on the historical volatility of the Company as well as several public entities that are similar to the Company. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term. The Company uses an expected dividend yield of zero as it does not expect to pay cash dividends for the foreseeable future. Upon issuance and at each reporting period, the fair value of each SARs award is estimated using the Black-Scholes option pricing model and is marked to market through stock-based compensation expense. SARs are liability-based awards as they may only be settled in cash.
The fair value of restricted stock awards (“RSAs”), including restricted stock awards with non-market performance and service conditions (“PSAs”) is determined based on the fair value of Aerie’s common stock on the date of grant. Compensation expense related to RSAs is recognized ratably over the vesting period. As the PSAs have multiple performance conditions, compensation expense is recognized for each vesting tranche over the respective requisite service period of each tranche if and when the Company’s management deems it probable that the performance conditions will be satisfied. Stock-based compensation related to stock options, RSAs and PSAs is expensed on a straight-line basis over the relevant vesting period, although the Company may recognize a cumulative true-up adjustment related to PSAs once a condition becomes probable of being satisfied if the related service period had commenced in a prior period.All stock-based compensation expense is recorded between selling, general and administrative, pre-approval commercial manufacturing and research and development costs in the consolidated statements of operations and comprehensive loss based upon the underlying employees’ roles within the Company. The Company accounts for forfeitures as they occur.
Investments
The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of certificates of deposit, commercial paper, corporate bonds and government agency securities that are classified as available-for-sale in accordance with ASC Topic 320, Investments—Debt and Equity Securities. The Company classifies investments available to fund current operations as current assets on its consolidated balance sheets. Investments are classified as long-term assets on the consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.
Available-for-sale investments in debt securities are recorded at fair value, with unrealized gains or losses included in comprehensive loss on the consolidated statements of operations and comprehensive loss and in accumulated other comprehensive loss on the consolidated balance sheets. Realized gains and losses, interest income earned on the Company’s cash, cash equivalents and investments, and amortization or accretion of discounts and premiums on investments are included within other income (expense), net. Interest income was $3.4 million, $1.8 million and $0.6 million for the years ended December 31, 2018, 2017 and 2016, respectively. Realized gains and losses are determined using the specific

identification method and are included as a component of other income (expense), net. Realized gains or losses were immaterial for the years ended December 31, 2018, 2017 and 2016.
The Company reviews investments in debt securities for other-than-temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. The Company did not recognize any impairments on its investments during the years ended December 31, 2018, 2017 or 2016.
Fair Value Measurements
The Company records certain financial assets and liabilities at fair value in accordance with the provisions of ASC Topic 820, Fair Value Measurements and Disclosures. As defined in the guidance, fair value, defined as an exit price, represents the amount that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, the guidance defines a three-tier value hierarchy that prioritizes the inputs used in the valuation methodologies in measuring fair value.
Level 1—Unadjusted quoted prices in active, accessible markets for identical assets or liabilities.
Level 2—Other inputs that are directly or indirectly observable in the marketplace.
Level 3—Unobservable inputs that are supported by little or no market activity.
The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
There were no transfers between the different levels of the fair value hierarchy in 2018 or in 2017.
Comprehensive Loss
Comprehensive loss is comprised of net loss and other comprehensive loss. Other comprehensive loss includes changes in stockholders’ equity that are excluded from net income (loss), specifically changes in unrealized gains and losses on the Company’s available-for-sale securities.
Income Taxes
Deferred tax assets or liabilities are recorded for temporary differences between financial statement and tax basis of assets and liabilities, using enacted rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that a deferred tax asset will not be realized. The Company has provided a full valuation allowance on its deferred tax assets that consist of federal and state net operating losses (“NOLs”), stock-based compensation and tax credits as of December 31, 2018 and 2017 (Note 10). The Company reduced its valuation allowance during the year ended December 31, 2017 for federal alternative minimum tax (“AMT”) credit carryforwards that became fully refundable under the Tax Act (defined herein). See Note 10 for additional information.
The Company recognizes the impact of an uncertain tax position in the consolidated financial statements only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities. The Company’s policy is to record interest and penalties on uncertain tax positions as income tax expense. The Company did not recognize interest or penalties on uncertain tax positions for the years ended December 31, 2018, 2017 or 2016. As of December 31, 2018 and 2017, the Company had no uncertain tax positions.
Adoption of New Accounting Standards
In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which amends ASC 350-40, Internal-Use Software, to include in its scope implementation costs of a cloud computing arrangement that is a service contract. Consequently, the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement, is aligned with the guidance on capitalizing costs associated with developing or obtaining internal-use software. This ASU is effective for the Company beginning January 1, 2019 and early adoption is permitted. The Company elected to early adopt this standard during the third quarter of 2018, which did not have a material impact on its consolidated financial statements and disclosures.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“SAB 118”) (“ASU 2018-05”), which adds guidance to clarify the treatment of income taxes based on changes enacted in December 2017 in H.R. 1 (referred to herein as the “Tax Act”). ASU 2018-05 incorporates references in ASC Topic 740 to SAB 118, which was issued in December 2017, to address the application of U.S. GAAP in situations when a registrant may not have the necessary information available in reasonable detail to complete the accounting for certain income tax effects. The guidance became effective immediately upon the enactment of the Tax Act in accordance with U.S. GAAP which requires deferred tax assets and liabilities to be revalued during the period in which new tax legislation is enacted. The Company’s final impact assessment on the consolidated financial statements did not materially change from its initial estimates.
In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), which clarifies when changes to the terms or conditions of share-based payment awards must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award’s fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance became effective for the Company beginning on January 1, 2018. The impact of the adoption of this guidance on its consolidated financial statements would be dependent on future modifications to share-based payment awards, if any.
In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which eliminates the exception to the principle in ASC Topic 740, Income Taxes,that generally requires comprehensive recognition of current and deferred income taxesfor all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. This ASU became effective for the Company on January 1, 2018 and was required to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to accumulated deficit as of the beginning of the period of adoption. At December 31, 2017, the Company had $2.1 million of income tax effects deferred from past intercompany transactions that were recorded as prepaid assets within other assets, net, at December 31, 2017 that were adjusted through accumulated deficit as of January 1, 2018.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”), which provides guidance related to the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance became effective for the Company beginning on January 1, 2018 and prescribes different transition methods for the various provisions. The adoption of ASU 2016-01 did not have a material impact on its consolidated financial statements and disclosures.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The standard states that an entity should recognize revenue based on the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB subsequently issued amendments to ASU 2014-09 that had the same effective date of January 1, 2018. The Company did not generate any revenue prior to the three months ended June 30, 2018, and therefore the adoption of ASC Topic 606 did not have an impact on the Company’s financial statements for any prior periods or upon adoption. Revenue from sales of Rhopressa®, as well as any other future revenue arrangements, are and will be recognized under the provisions of ASC Topic 606.
In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The new standard clarifies the definition of a business and provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The new standard was effective for the Company beginning on January 1, 2018; however, Aerie elected to early adopt this standard as of July 1, 2017. Under this guidance, the October 4, 2017 transaction to acquire assets from Envisia was determined to meet the criteria of an asset acquisition rather than a business combination resulting in a $24.8 million charge to research and development expense on the consolidated statement of operations and comprehensive loss in the three months ended December 31, 2017. See Note 1 for additional information.
Recently Issued Accounting Standards
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820-10): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC Topic 820, Fair Value Measurements and Disclosures. Under this ASU, certain disclosure

requirements for fair value measurements are eliminated, amended or added. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance is effective for the Company beginning on January 1, 2020 and prescribes different transition methods for the various provisions. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements and disclosures.
In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), which expands the scope of ASC Topic 718, Compensation-Stock Compensation to include share-based payments issued to non-employees for goods or services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. This ASU is effective for the Company beginning January 1, 2019, including interim periods within that fiscal year, but early adoption is permitted. The Company does not expect the adoption of ASU 2018-07 to have a material impact on its consolidated financial statements and disclosures.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the loss is probable of occurring. Under this ASU, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down of the security. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses (“ASU 2018-19”), which clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. The guidance is effective for the Company beginning on January 1, 2020, with early adoption permitted beginning on January 1, 2019. The new guidance prescribes different transition methods for the various provisions. The Company does not expect the adoption of ASU 2016-13 or ASU 2018-19 to have a material impact on its consolidated financial statements and disclosures.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and for those leases that have lease terms of more than 12 months. In July 2018, the FASB issued both ASU 2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”) and ASU 2018-11, Leases (Topic 842)-Targeted Improvements (“ASU 2018-11”), which provides additional guidance or clarifications affecting certain aspects of ASU 2016-02 and certain practical expedients. Further, the updated guidance allows an additional transition method to apply the new leases standard at the adoption date, as compared to the beginning of the earliest period presented, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. ASU 2016-02, ASU 2018-10 and ASU 2018-11 were effective for the Company beginning on January 1, 2019, and all annual and interim periods thereafter. The Company has elected the transition method described in ASU 2018-11 at the adoption date of January 1, 2019. The Company is currently finalizing its evaluation of the impact of ASU 2016-02, ASU 2018-10 and ASU 2018-11 on its consolidated financial statements and disclosures related to its existing operating leases and a lease space for which the Company has historically applied build-to-suit accounting. The Company will recognize a right of use asset and corresponding lease liability related to its operating leases as of the date of adoption. The Company is also in process of finalizing its processes and internal controls required to comply with the new lease accounting and disclosure requirements set by the new standard on an ongoing basis.
Net Loss per Common Share
Basic net loss per common share (“Basic EPS”) is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration and are therefore included in the calculation of the weighted-average number of shares of common stock as common stock equivalents. Diluted net loss per share (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss used in calculating Basic EPS may be adjusted for certain items related to the dilutive securities.
For all periods presented, Aerie’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have had an anti-dilutive effect.
The potential common stock equivalents that have been excluded from the computation of Diluted EPS consist of the following:

3.    Revenue Recognition
In accordance with ASC Topic 606, the Company recognizes revenues when its customers obtain control of its product in an amount that reflects the consideration it expects to receive from its customers in exchange for that product. To determine revenue recognition for contracts that are determined to be in scope of ASC Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when such performance obligation is satisfied. Shipping and handling costs related to the Company’s product sales are included in selling, general and administrative expenses.
Net product revenues for the year ended December 31, 2018 were derived from sales of Rhopressa® in the United States to customers, which include a limited number of national and select regional wholesalers (the “Distributors”). These Distributors subsequently resell the product, primarily to retail pharmacies that dispense the product to patients. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less or the amount is immaterial. The product that is ultimately used by patients is generally covered by third-party payers, such as government or private healthcare insurers and pharmacy benefit managers (“Third-party Payers”) and may be subject to rebates and discounts payable directly to those Third-party Payers.
Product revenue is recorded net of trade discounts, allowances, rebates, chargebacks, estimated returns and other incentives, discussed below. These reserves are classified as either reductions of accounts receivable or as current liabilities. Amounts billed or invoiced are included in accounts receivable, net on the consolidated balance sheet. The Company did not have any contract assets (unbilled receivables) at December 31, 2018, as customer invoicing generally occurs before or at the time of revenue recognition. The Company did not have any contract liabilities at December 31, 2018, as the Company did not receive payments in advance of fulfilling its performance obligations to its customers.
Net product revenue is typically recognized when Distributors obtain control of the Company’s product, which occurs at a point in time, typically upon delivery of Rhopressa® to the Distributors. For the year ended December 31, 2018, three Distributors accounted for 33.9%, 33.3% and 29.7% of total revenues, respectively. The Company evaluates the creditworthiness of each of its Distributors to determine whether it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur. The Company does not assess whether a contract has a significant financing component if the expectation is such that the period between the transfer of the promised goods to the customer and the receipt of payment will be less than one year. Standard credit terms do not exceed 75 days.
The Company calculates its net product revenue based on the wholesale acquisition cost that the Company charges its Distributors for Rhopressa® less provisions for (i) trade discounts and allowances, such as discounts for prompt payment and Distributor fees, (ii) estimated rebates to Third-party Payers, estimated payments for Medicare Part D prescription drug program coverage gap (commonly called the “donut hole”), patient co-pay program coupon utilization, chargebacks and other discount programs and (iii) reserves for expected product returns. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, known market events and trends, industry data and forecasted customer mix. Provisions for revenue reserves reduced product revenues by $19.6 million in aggregate for the year ended December 31, 2018. The transaction price may be subject to constraint and is included in the net product revenues only to the extent that it is probable that a significant reversal of the amount of the cumulative revenues recognized will not occur in a future period. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which could have an impact on earnings in the period of adjustment.


Trade Discounts and Allowances: The Company generally provides discounts on sales of Rhopressa® to its Distributors for prompt payment and pays fees for distribution services and for certain data that Distributors provide to the Company. The Company expects its Distributors to earn these discounts and fees, and accordingly deducts the full amount of these discounts and fees from its gross product revenues at the time such revenues are recognized.
Rebates, Chargebacks and Other Discounts: The Company contracts with Third-party Payers for coverage and reimbursement of Rhopressa®. The Company estimates the rebates and chargebacks it expects to be obligated to provide to Third-party Payers and deducts these estimated amounts from its gross product revenue at the time the revenue is recognized. The Company estimates the rebates and chargebacks that it expects to be obligated to provide to Third-party Payers based upon (i) the Company's contracts and negotiations with these Third-party Payers, (ii) estimates regarding the payer mix for Rhopressa® and (iii) historical industry information regarding the payer mix for comparable pharmaceutical products and product portfolios. Other discounts include the Company’s co-pay assistance coupon programs for commercially-insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to pay associated with product that has been recognized as revenue.
Product Returns: The Company estimates the amount of Rhopressa® that will be returned and deducts these estimated amounts from its gross revenue at the time the revenue is recognized. The Company currently estimates product returns based on historical industry information regarding rates for comparable pharmaceutical products and product portfolios, the estimated remaining shelf life of Rhopressa® shipped to Distributors, and contractual agreements with the Company's Distributors intended to limit the amount of inventory they maintain. Reporting from the Distributors includes Distributor sales and inventory held by Distributors, which provides the Company with visibility into the distribution channel to determine when product would be eligible to be returned.

Depreciation expense was $2.4 million, $1.4 million and $1.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Manufacturing Plant Build-Out
In January 2017, the Company entered into a Euro-denominated lease agreement, expiring in September 2037, for a new manufacturing plant in Athlone, Ireland, under which the Company is leasing approximately 30,000 square feet of interior floor space for build-out. The Company is permitted to terminate the lease beginning in September 2027.
Minimum expected lease payments were as follows at December 31, 2018 (a):
(in thousands) 
2019$250
2020250
2021250
2022259

        Total minimum lease payments (b)

(a) Uses foreign exchange rates in effect at December 31, 2018.
(b) This represents the obligation through the minimum lease term of September 2027. If the Company utilizes the leased space through the full term of the lease, expiring in September 2037, the total rental payments would be $5.9 million.
The Company is not the legal owner of the leased space. However, in accordance with ASC Topic 840, Leases, the Company is deemed to be the owner of the leased space, including the building shell, during the construction period because of the Company’s expected level of direct financial and operational involvement in the substantial tenant improvements required. As a result, the Company capitalized approximately $4.2 million as a build-to-suit asset within property, plant and equipment, net and recognized a corresponding build-to-suit facility lease obligation as a liability on its consolidated balance sheets equal to the estimated replacement cost of the building at the inception of the lease.
Lease payments made under the lease will be allocated to interest expense and the build-to-suit facility lease obligation based on the implicit rate of the build-to-suit facility lease obligation. The build-to-suit facility lease obligation was approximately $4.5 million as of December 31, 2018, of which $0.2 million was classified as other current liabilities as of December 31, 2018. The build-to-suit facility lease obligation was approximately $5.7 million as of December 31, 2017, of which $0.3 million was classified as other current liabilities as of December 31, 2017. The lease obligation is denominated in Euros and is remeasured to U.S. dollars at the balance sheet date with any foreign exchange gain or loss recognized within other income (expense), net on the consolidated statements of operations and comprehensive loss. Unrealized foreign currency gain related to the remeasurement of the build-to-suit facility lease obligation for the year ended December 31, 2018 was $0.2


million. The Company had an unrealized foreign currency loss related to the measurement of the lease obligation of $0.6 million for the year ended December 31, 2017.
Additionally, construction costs incurred as part of the build-out and tenant improvements are also capitalized within property, plant and equipment, net. Costs of approximately $24.8 million have been capitalized during the year ended December 31, 2018, related to both equipment purchases and the build-out of the facility. Once these costs are no longer considered construction-in-progress they will be moved to the respective asset category within property, plant and equipment and will begin depreciating.

2014 Convertible Notes
In September 2014, the Company issued $125.0 million aggregate principal amount of the 2014 Convertible Notes to Deerfield Partners, L.P., Deerfield International Master Fund, L.P., Deerfield Private Design Fund III, L.P., Deerfield Special Situations Fund, L.P. and Deerfield Special Situations International Master Fund, L.P., collectively with their transferees, “Deerfield.” The 2014 Convertible Notes were issued pursuant to a note purchase agreement (as amended and supplemented from time to time, the “Note Purchase Agreement”), dated as of September 8, 2014, among Aerie and the Deerfield entities party thereto.
The 2014 Convertible Notes were scheduled to mature on the seventh anniversary from the date of issuance, unless earlier converted. The 2014 Convertible Notes were convertible at any time at the option of Deerfield, in whole or in part, into shares of common stock. In July 2018, Deerfield converted the entire outstanding principal amount of the 2014 Convertible Notes into shares of Aerie common stock.
The 2014 Convertible Notes bore interest at a rate of 1.75% per annum payable quarterly in arrears on the first business day of each January, April, July and October. The Company recorded the 2014 Convertible Notes as long-term debt at face value less $2.1 million in debt discount and issuance costs incurred at the time of the transaction, which were being amortized to interest expense using the effective interest method through the conversion of the 2014 Convertible Notes.

Conversion of 2014 Convertible Notes
On July 23, 2018, Aerie entered into an Exchange and Termination Agreement (the “Exchange and Termination Agreement”) with Deerfield Private Design Fund III, L.P., Deerfield Partners, L.P. and Deerfield Special Situations Fund, L.P. (collectively, the “Holders”). Pursuant to the Exchange and Termination Agreement, (i) the Holders converted the entire outstanding principal amount of the 2014 Convertible Notes into 5,040,323 shares of Aerie common stock (the “Conversion Shares”) in accordance with the terms of the 2014 Convertible Notes, which was recognized in stockholders’ equity, (ii) Aerie issued the Conversion Shares, and (iii) Aerie paid accrued and unpaid interest on the Convertible Notes through July 23, 2018.
In addition, as mutually agreed to with the Holders in order to complete the conversion on the date of the Exchange and Termination Agreement, Aerie issued an additional 329,124 shares of Aerie common stock (the “Additional Shares”) to the Holders. Aerie expensed the value of the Additional Shares in the amount of $24.1 million to other expense during the year ended December 31, 2018.
Entry into Credit Facility
On July 23, 2018, Aerie entered into a credit agreement (as amended on August 7, 2018) with certain entities affiliated with Deerfield Management Company L.P. providing for a $100 million credit facility. The credit facility includes fees upon drawdown of 1.75% of amounts drawn, an 8.625% annual interest rate on drawn amounts, and annual fees on undrawn amounts of 1.5%. There is also an exit fee of $1.5 million payable upon termination of the credit facility (whether at maturity or otherwise). The allowable draw period ends two years from the effective date of the credit facility. Fees on undrawn amounts are not payable until July 23, 2020, and no principal payments will be due on drawn amounts, if any, until July 23, 2020. The credit facility matures on July 23, 2024 in respect of any drawn amounts. The credit facility includes affirmative and negative covenants and prepayment terms. No funds were drawn at closing or as of December 31, 2018.
Interest expense was $2.5 million for the year ended December 31, 2018, and included amortization of debt discount and issuance costs related to the 2014 Convertible Notes through the date of conversion as well as issuance costs and fees related to the credit facility. Interest expense was $2.4 million and $2.5 million for the years ended December 31, 2017 and 2016, respectively, which included amortization of debt discount and issuance costs related to the 2014 Convertible Notes.

In December 2017, the Tax Act was signed into law and enacted significant changes to the Internal Revenue Code of 1986, as amended. This tax legislation, among other changes, reduced the federal corporate income tax rate from 35% to 21% effective January 1, 2018.Under U.S. GAAP, deferred tax assets and liabilities are required to be revalued during the period in which the new tax legislation is enacted. Therefore, the deferred tax assets and liabilities were remeasured as of December 31, 2017, resulting in a reduction of the deferred tax asset balance and corresponding valuation allowance of $34.2 million due to the enacted changes in tax rate. The Tax Act also repealed the corporate AMT for tax years beginning after December 31, 2017, and provides that existing AMT credit carryovers are refundable in tax years beginning after December 31, 2017. The Company has approximately $1.7 million of AMT credit carryovers that are expected to be fully refunded between 2019 and 2022, of which $0.3 million is recorded as a current receivable with the remainder recorded as a non-current receivable within other assets on the consolidated balance sheet as of December 31, 2018. The Company reduced the valuation allowance on its deferred tax assets by $1.7 million and recognized an income tax benefit of the same amount during the year ended December 31, 2017 related to these federal AMT credit carryforwards.
At December 31, 2018, the Company had federal and state NOL carryforwards of approximately $387.7 million and $411.2 million, respectively. If not utilized, federal NOLs that arose prior to 2018 and state NOLs will begin to expire at various dates beginning in 2031 and 2024, respectively. Federal NOLs that arose on or after January 1, 2018 can be carried forward indefinitely against future income, but can only be used to offset a maximum of 80% of the Company’s federal taxable income in any year. As of December 31, 2018, the Company also had foreign NOL carryforwards of $44.1 million, which are available solely to offset taxable income of its foreign subsidiaries, subject to any applicable limitations under foreign law.
Federal NOLs and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities.
Realization of future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. The Company provides a valuation allowance when it is more likely than not that deferred tax assets will not be realized. Due to the Company’s history of operating losses and lack of available evidence supporting future taxable income, the Company maintains a valuation allowance on all of its deferred tax assets as of December 31, 2018. The increase in valuation allowance as of December 31, 2018 as compared to December 31, 2017 was primarily the result of the increase in NOL carryforwards.
The Company files income tax returns in the United States, Ireland and Malta. The federal and state income tax returns are open under the statute of limitations subject to tax examinations for the tax years ended December 31, 2014 through December 31, 2018. To the extent the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the IRS or state tax authorities to the extent utilized in a future period.
11.    Stockholders’ Equity

Holders of the SARs are entitled under the terms of the Plans to receive cash payments calculated based on the excess of Aerie’s common stock price over the exercise price in their award; consequently, these awards are accounted for as liability-classified awards and the Company measures compensation cost based on their estimated fair value at each reporting date, net of actual forfeitures, if any.
Employee Stock Purchase Plan
The Company maintains the 2013 Employee Stock Purchase Plan (the “Purchase Plan”) under which substantially all employees may purchase Aerie’s common stock through payroll deductions and lump sum contributions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of the offering periods. Employees may not purchase more than the fair value equivalent of $25,000 of stock during any calendar year. The Purchase Plan provides for the issuance of up to 645,814 shares of Aerie’s common stock.
