our stated objective of building a major ophthalmic pharmaceutical company.
By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics, industry change and other factors beyond our control, and depend on regulatory approvals and economic and other environmental circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. We discuss many of these risks under the heading “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016,2017, as filed with the Securities and Exchange Commission (“SEC”) on March 9, 2017,1, 2018, and other documents we have filed or furnished with the SEC. You should not rely upon forward-looking statements as predictions of future events.

ii


In particular, ourFDA approval of Rhopressa® does not constitute FDA approval of RoclatanTM, and there can be no assurance that we will receive FDA approval for RoclatanTM or any future product candidates. FDA approval of Rhopressa® also does not constitute regulatory approval of Rhopressa® in jurisdictions outside the United States, and there can be no assurance that Rhopressa® will obtain regulatory approval in other jurisdictions. Our receipt of a Prescription Drug User Fee Act (“PDUFA”) goal date notification for RoclatanTMdoes not constitute FDA approval of the RhopressaRoclatanTM New Drug Application (“NDA”), and there can be no assurance that the FDA will complete its review by the PDUFA goal date of March 14, 2019, that the FDA will not require changes or additional data whether as a result of recommendations, if any, made by any FDA advisory committee or otherwise, that must be made or received before it will approve the NDA, if ever, or that the FDA will approve the NDA. In addition, the preclinical research discussed in this report is preliminary and the outcome of such preclinical studies may not be predictive of the outcome of later clinical trials. Any future clinical trial results may not demonstrate safety and efficacy sufficient to obtain regulatory approval related to the preclinical research findings discussed in this report, and we may suspend or discontinue research programs at any time for any reason.
You should not rely upon forward-looking statements as predictions of future events. Although we believe that we have a reasonable basis for each forward-looking statement contained in this report, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate, may differ materially from the forward-looking statements contained in this report. In addition, even if our results of operations, financial condition and liquidity, and events in the industry in which we operate, are consistent with the forward-looking statements contained in this report, they may not be predictive of results or developments in future periods.
Any forward-looking statements that we make in this report speak only as of the date of this report. Except as required by law, we are under no duty to update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this report.

AERIE PHARMACEUTICALS, INC.
Notes to the Condensed Consolidated Financial Statements
(Unaudited)
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 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, retina diseases and other diseases of the eye.
In 2015, the Company revised its corporate structure to align with its business strategy outside of North America by establishing Aerie Limited and Aerie Ireland Limited. Aerie assigned the beneficial rights to its non-U.S. and non-Canadian intellectual property for its lead product candidates to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, Aerie and Aerie Limited entered into a research and development cost sharing agreement pursuant to which Aerie and Aerie Limited will share the costs of the development of intellectual property and Aerie Limited and Aerie Ireland Limited entered into a license arrangement pursuant to which Aerie Ireland Limited will develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment.
In 2016, Aerie assigned the beneficial rights to certain of Aerie’s intellectual property in the U.S. and Canada to Aerie Distribution, and amended and restated the research and development cost sharing agreement to transfer Aerie’s rights and obligations under the agreement to Aerie Distribution.
The Company has its principal executive offices in Irvine, California,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, RoclatanTM(netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% (“RoclatanTM”), both designed to reduce elevated intraocular pressure (“IOP”) in patients with open-angle glaucoma or ocular hypertension. The Company intends to commercialize Rhopressa® and RoclatanTM, if approved, on its own in North American markets. The Company’s strategy also includes pursuing regulatory approval for Rhopressa® and RoclatanTM in Europe and Japan on its own.
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. The Company also intends to file a marketing authorization application with the European Medicines Agency for Rhopressa® by the end of 2018. Additionally, the Company completed a Phase 1 clinical trial and commenced a Phase 2 clinical trial in the United States, which are designed to support meeting the requirements of Japan’s Pharmaceuticals and Medical Devices Agency for potential regulatory submission of Rhopressa® in Japan. These clinical trials have included Japanese and Japanese-American subjects. The Company is also planning to initiate an additional Phase 2 clinical trial on Japanese patients in Japan to support subsequent Phase 3 registration trials that are expected to be conducted in Japan.
The Company’s advanced-stage product candidate, RoclatanTM, 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 under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, which provides for an abbreviated approval pathway, since RoclatanTM is a fixed dose combination of two FDA-approved drugs in the United States. On July 23, 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. The Company is currently conducting a Phase 3 trial, named Mercury 3, in Europe comparing RoclatanTMto Ganfort®, a fixed-dose combination product of bimatoprost (a prostaglandin analog) and timolol marketed in Europe, which if successful, is expected to improve its commercialization prospects in that region. Mercury 3 is not yet commenced commercial operationsnecessary for approval in the United States.
On July 31, 2017, the Company entered into a collaborative research, development and therefore haslicensing 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 evaluating its application to the 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. Preclinical experiments have demonstrated early success in conjunction with Aerie’s preclinical molecule, AR-13503, including demonstration of linear, sustained elution rates over several months and achievement of target retinal drug concentrations. On August 1, 2018, the Company announced the expansion of its 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.
On October 4, 2017, the Company entered into an Asset Purchase Agreement (the “Agreement”) with Envisia Therapeutics Inc. (“Envisia”) to acquire the rights to use PRINT® technology in ophthalmology, as well as rights relating to Envisia’s preclinical dexamethasone steroid implant for the potential treatment of diabetic macular edema that utilizes the PRINT® technology, referred to as AR-1105. The PRINT® technology is a proprietary system capable of creating precisely-engineered sustained-release products utilizing fully-scalable manufacturing processes. The Company will also focus on using PRINT® to manufacture injectable implants containing AR-13503, potentially in conjunction with the bio-erodible polymer from DSM.
Prior to the three months ended June 30, 2018, the Company had not generated any revenue. Aerie commenced generating product revenue.revenues related to sales of Rhopressa® in the second quarter of 2018 following its commercial launch of

Rhopressa® in the United States in late April 2018. The Company’s activities sincefrom inception haveuntil the commercial launch of Rhopressa® in the United States had 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 current 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 (Note 10) and issuance of convertible notes (Note 7)9).
Subsequent to June 30, 2018, all of the Company’s $125.0 million aggregate principal amount of senior secured convertible notes (the “2014 Convertible Notes”) were converted into shares of Aerie common stock. In addition, the Company entered into a $100 million senior secured delayed draw term loan facility that matures on July 23, 2024. See Note 13, “Subsequent Events,” for additional information.
If the Company does not successfully commercialize Rhopressa®, RoclatanTM or any of its currentfuture product candidates, it may be unable to generate product revenue or achieve profitability. Accordingly, the Company may be required to draw down on the credit facility it entered into in July 2018, or obtain further funding through other public or private offerings, debt financing,financings, 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 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
The Company’s interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 20162017 included in the Company’s Annual Report on Form 10-K.10-K filed with the Securities and Exchange Commission (“SEC”) on March 1, 2018 (“2017 Form 10-K”). The results for the three and six months ended June 30, 20172018 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

Principles of Consolidation
The interim condensed 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 revenue recognition, the valuation of stock optionsstock-based awards and operating expense accruals. Actual results could differ from the Company’s estimates.
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 to 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 three and six months ended June 30, 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, “Revenue Recognition,” for more information.

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 condensed consolidated balance sheet.
The Company depends on single source suppliers for the active pharmaceutical ingredient in Rhopressa® and the manufacture of finished product. The Company is in the process of adding a second contract manufacturer, which it expects may produce commercial supply by as early as the end of 2018. In addition, the Company is building a new manufacturing plant in Athlone, Ireland, which is expected to produce commercial supplies of Rhopressa® and, if approved, RoclatanTM. Commercial supply from the Ireland manufacturing plant is expected to be available by 2020.
Inventories
Prior to the date the Company obtains regulatory approval for its product candidates, manufacturing costs related to commercial production for such product candidate are expensed as selling, general and administrative expense. Once regulatory approval is obtained, the Company capitalizes such costs as inventory. Inventories are stated at the lower of cost or estimated realizable value. The Company determines the cost of inventory using the first-in, first-out (“FIFO”) method.
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, which primarily relates to the build-out of the Company’s manufacturing plant in Ireland (Note 7). 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 and computer equipment3 years
Leasehold improvementsLower of estimated useful life or term of lease
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 and corporate bonds and government agency securities that are classified as available-for-sale in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”)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 inas other comprehensive loss on the condensed consolidated statements of operations and comprehensive loss and inas accumulated other comprehensive loss on the condensed consolidated balance sheets. Realized gains and losses, are determined usinginterest income earned on the specific identification methodCompany’s cash, cash equivalents and investments, and amortization or accretion of discounts and premiums on investments are included as a component ofwithin other income (expense), net (Note 3). There were no realized gains or losses recognizednet. Interest income was $0.9 million and $1.7 million for the three and six months ended June 30, 2018, respectively, and $0.4 million and $0.7 million for the three and six months ended June 30, 2017, or 2016.respectively. Realized losses of $0.2 million were reclassified out of accumulated other comprehensive loss and recognized within other income
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

There were no investments with a fair value that was significantly lower thanrealized gains or losses recognized during the amortized cost basisthree or any investments that had been in an unrealized loss position for a significant period.six months ended June 30, 2017.
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 and short-term investments, approximate their respective carrying values due to the short-term nature of these instruments. The estimated fair value of the 2014 Convertible Notes (as defined in Note 7) was $287.3 million and $209.6 million as of June 30, 2017 and December 31, 2016, respectively. The increase in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the increase in the closing price of Aerie’s common stock on June 30, 2017 as compared to December 31, 2016.
Recent Accounting Pronouncements
In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies when changes to the terms or conditions of a share-based payment award 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 is effective for the Company beginning on January 1, 2018. Early adoption is permitted. The Company is evaluating the impact of the adoption of this guidance on its consolidated financial statements but does not expect it to have a material impact.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which eliminates the exception to the principle in ASC 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. The new standard is effective for the Company beginning January 1, 2018, with early adoption permitted, and must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the impact of this accounting standard update 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, 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 new standard, 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. The new standard is effective for the Company beginning January 1, 2020. Early adoption is permitted for fiscal year beginning January 1, 2019. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements and disclosures.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), 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. The guidance is effective for annual periods beginning after December 15, 2018, and all annual and interim periods thereafter, with early adoption permitted, and must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. The Company is currently evaluating the impact of this accounting standard update on the its consolidated financial statements and disclosures.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, 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 is effective for the Company beginning January 1, 2018, with early adoption permitted. The new guidance prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of this accounting standard update on the its consolidated financial statements and disclosures.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). 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 has subsequently issued amendments to ASU 2014-09 that have the same effective date of January 1, 2018. The future impact of ASU 2014-09 will be dependent on the nature of the Company’s future revenue contracts and arrangements, if any.
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 is 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:

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.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.
The following tables summarizeThere were no transfers between the different levels of 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:

Convertible Notes
As of June 30, 2017 and December 31, 2016, the estimated fair value of the 2014 Convertible Notes was $287.3 million and $209.6 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 increase in the estimated fair value of the 2014 Convertible Notes was primarily attributable to the increase in the closing price of Aerie’s common stock on June 30, 2017 as compared to December 31, 2016. 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.

7. Convertible Notes
On September 30, 2014, Aerie issued $125.0 million aggregate principal amount of senior secured convertible notes (“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. 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. (together with the other Deerfield entities listed above, “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 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 are guaranteed on a senior secured basis by Aerie Distribution. The 2014 Convertible Notes constitute the senior secured obligations of Aerie and Aerie Distribution, collateralized by a first priority security interest in substantially all of the assets of Aerie and Aerie Distribution. The Note Purchase Agreement provides that, upon the request of Aerie, Deerfield will release all of the liens on the collateral and the security agreement will terminate if both of the following occur: (i) beginning one month after FDA approval of either Rhopressa or Roclatan, 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 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.
At closing, Aerie paid Deerfield a one-time transaction fee of $0.6 million. In addition, Aerie reimbursed Deerfield in the amount of $0.3 million 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 shares of common stock or receive 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 Note Purchase Agreement 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 and its subsidiaries’ assets. As of June 30, 2017, Aerie was in compliance with the covenants. The Note Purchase Agreement also provides for certain events of default, including the failure to pay principal and interest when due; inaccuracies in Aerie’s or Aerie Distribution’s representations and warranties to Deerfield; failure to comply with any of the covenants; Aerie’s or Aerie Distribution’s insolvency or the occurrence of certain bankruptcy-related events; certain judgments against Aerie and its subsidiaries; 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 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.
In connection with the IP Assignment, Aerie granted Deerfield a security interest in certain intercompany promissory notes and pledged 65% of the voting stock of Aerie Limited. Upon the request of Aerie, Deerfield will release the lien on the intercompany promissory notes under certain circumstances.
Unamortized debt discounts were $1.3 million as of June 30, 2017. Debt discounts are amortized using the effective interest method through the earlier of maturity or the conversion of the 2014 Convertible Notes.

The table below summarizes the carrying value of the 2014 Convertible Notes as of June 30, 2017:

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. Total expected rental payments, using foreign exchange rates in effect at June 30, 2017, are approximately $2.7 million through September 2027 and approximately $6.2 million through the expiration of the lease.
The Company is not the legal owner of the leased space. However, in accordance with ASC 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.
Additionally, construction costs incurred as part of the build-out and tenant improvements will also be capitalized within property, plant and equipment, net. Costs of approximately $5.2 million have been capitalized through June 30, 2017 related to both equipment purchases and the build-out of the facility. Rental 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 $4.6 million as of June 30, 2017, of which $0.2 million was classified as other current liabilities as of June 30, 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 condensed consolidated statements of operations and comprehensive loss. Unrealized foreign currency loss related to the remeasurement of the lease obligation for the six months ended June 30, 2017 was $0.4 million.
9. Stockholders’ Equity
From the Company’s initial public offering (“IPO”) through December 31, 2016, the Company has issued and sold (1) a total of 5,933,712 shares of common stock under its “at-the-market” sales agreements and received net proceeds of approximately $146.6 million, after deducting commissions at a rate of up to 3% of the gross sales price per share sold and other fees and expenses, and (2) 2,542,373 shares of common stock pursuant to an underwriting agreement, dated September 15, 2016, for which the Company received net proceeds of approximately $71.0 million, after deducting the underwriting discount, fees and expenses of approximately $4.0 million.
During the six months ended June 30, 2017, the Company has issued and sold 906,858 shares of common stock under its “at-the-market” sales agreement, for which the Company received net proceeds of approximately $49.3 million, after deducting commissions, fees and expenses of $0.6 million. Further, on May 25, 2017, the Company entered into an underwriting agreement relating to the registered public offering of 1,395,349 shares of the Company’s common stock at a price to the public of $53.75 per share. The Company received net proceeds of approximately $72.7 million, after deducting underwriting discounts, fees and expenses of $2.3 million.

The estimated fair value of options to purchase common stock 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 the required service is performed. The fair value of RSAsrestricted stock awards (“RSAs”) granted is based on the market value of Aerie’s common stock on the date of grant. Compensation expense related to time-based RSAs is expensed on a straight-line basis over the vesting period. For RSAs with non-market performance conditions, the Company evaluates the criteria for each grant to determine the probability that the performance condition will be achieved. Compensation expense for RSAs with non-market performance conditions is recognized over the respective service period when it is deemed probable that the performance condition will be satisfied. Upon issuance and at each reporting period, the fair value of each stock appreciation rights (“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. 
Adoption of New Accounting Standards
In March 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (“SAB 118”), which adds guidance to clarify the treatment of income taxes based on changes enacted on December 22, 2017 in H.R. 1 (commonly referred to as the “Tax Act”). ASU 2018-05 incorporates references in ASC Topic 740 to SAB 118, which was issued on December 22, 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 will be completed as additional information becomes available, but no later than one year from the enactment of the Tax Act.
In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, 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, 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, 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). 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. 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.
Recent Accounting Pronouncements
In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of ASC Topic 718, Compensation—Stock Compensation to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees 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, 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. This ASU 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 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 ASU 2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”), which provides additional guidance or clarifications affecting certain aspects of ASU 2016-02. ASU 2016-02 and ASU 2018-10 are effective for the Company beginning on January 1, 2019, and all annual and interim periods thereafter, with early adoption permitted, and must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements and provides for certain practical expedients. The Company is currently evaluating the impact of ASU 2016-02 and ASU 2018-10 on its consolidated financial statements and disclosures.
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 is 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 three and six months ended June 30, 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. The Company has already obtained coverage in some commercial and Medicare Part D plans and is in the process of increasing those levels of coverage. In the glaucoma market in the United States, approximately half of the volumes are covered under commercial plans and half under Medicare Part D. Medicare Part D coverage would normally commence for Rhopressa®, as with other new products, on January 1, 2019. However, there have been early acceptances of Rhopressa® onto certain Medicare Part D plans, commencing as early as June 1, 2018.
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 based on the expected method of settlement. Amounts billed or invoiced are included in accounts receivable, net on the condensed consolidated balance sheet. The Company did not have any contract assets (unbilled receivables) at June 30, 2018, as customer invoicing generally occurs before or at the time of revenue recognition. The Company did not have any contract liabilities at June 30, 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 three months ended June 30, 2018, three Distributors accounted for 34%, 33% and 30% 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. 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.
The Company calculates its net product revenue based on the wholesale acquisition cost that the Company charges its Distributors for Rhopressa® less variable consideration. Variable consideration consists of estimates relating to (i) trade discounts and allowances, such as discounts for prompt payment and Distributor fees, (ii) estimated rebates, chargebacks and other discounts payable to Third-party Payers 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. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, 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 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.

Convertible Notes
As of June 30, 2018 and December 31, 2017, the estimated fair value of the $125.0 million aggregate principal amount of the 2014 Convertible Notes was $361.7 million and $327.6 million, respectively. The estimated fair value of the 2014 Convertible Notes require the use of Level 3 unobservable inputs and subjective assumptions. 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.

Manufacturing Plant Build-Out
In January 2017, the Company had $49.3entered 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.

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 condensed consolidated balance sheets equal to the estimated replacement cost of unrecognized compensation expensethe building at the inception of the lease. Additionally, equipment and construction costs incurred as part of the build-out are also capitalized within property, plant and equipment, net, as construction-in-progress. Capital expenditures related to options grantedthe manufacturing plant totaled approximately $21.2 million during the six months ended June 30, 2018.
Rental payments made under its equity plans. Thisthe lease will be allocated to interest expense is expected to be recognized over a weighted average periodand the build-to-suit facility lease obligation based on the implicit rate of 2.9 yearsthe build-to-suit facility lease obligation. The build-to-suit facility lease obligation was approximately $4.7 million as of June 30, 2018, of which $0.3 million was classified as other current liabilities. The build-to-suit facility lease obligation was approximately $4.9 million as of December 31, 2017. The weighted average remaining contractual lifelease 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 condensed consolidated statements of operations and comprehensive loss. Unrealized foreign currency gain related to the remeasurement of the lease obligation was $0.3 million and $0.1 million for the three and six months ended June 30, 2018, respectively. The Company had unrealized foreign currency losses related to the remeasurement of the lease obligation of $0.3 million and $0.4 million for the three and six months ended June 30, 2017.

In September 2014, Aerie 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. In July 2018, Deerfield converted the entire outstanding principal amount of the 2014 Convertible Notes into shares of Aerie common stock. See Note 13, “Subsequent Events,” for additional information.
The 2014 Convertible Notes were guaranteed on a senior secured basis by Aerie Distribution. The 2014 Convertible Notes constituted the senior secured obligations of Aerie and Aerie Distribution, collateralized by a first-priority security interest in substantially all outstanding optionsof the assets of Aerie and Aerie Distribution.
The 2014 Convertible Notes were convertible at any time at the option of Deerfield, in whole or in part, into shares of common stock. The initial conversion price was $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 Note Purchase Agreement contained 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 and its subsidiaries’ assets. As of June 30, 2018, Aerie was in compliance with the covenants.
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 maturity of the 2014 Convertible Notes.
The table below summarizes the carrying value of the 2014 Convertible Notes as of June 30, 2018 and December 31, 2017:

13. Subsequent Events
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 Common Stock (the “Conversion Shares”) in accordance with the terms of the 2014 Convertible Notes, (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 Common Stock (the “Additional Shares”) to the Holders. Aerie expects to expense the value of the Additional Shares in the amount of approximately $24 million during the third quarter of 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 senior secured delayed draw term loan facility (the “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%. The allowable draw period ends two years from the effective date of the credit facility. Fees on undrawn amounts accrue but 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. The credit facility has certain covenants and prepayment provisions and may be terminated by Aerie at any time for a one-time fee of $1.5 million. No funds were drawn at closing.
Collaboration Agreement with DSM

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. The Collaboration Agreement also includes contingent payments that may be due to DSM upon the achievement of certain development and regulatory milestones. Aerie would also pay royalties to DSM when products are commercialized under this Collaborative Agreement, if any.

Item 2. 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 unaudited condensed consolidated financial statements and related notes that appear elsewhere in this report and with our audited financial statements and related notes and management’s discussion and analysis of financial condition and results of operations included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016,2017, as filed with the SEC on March 9, 1, 2018 (“2017 (“2016 Form 10-K”). This 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 our 20162017 Form 10-K and other documents we have filed or furnished with the SEC 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, retina diseasesand other diseases of the eye. Our strategy is to advancecommercialize our U.S. Food and Drug Administration (“FDA”) approved product, candidates, RhopressaTM® (netarsudil ophthalmic solution) 0.02% (“RhopressaTM®”), in North American markets and advance our product candidate, RoclatanTM (netarsudil/(netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% (“RoclatanTM”), to regulatory approvalapproval. We launched Rhopressa® in the United States at the end of April 2018. Rhopressa® is now being sold to national and commercialize theseregional U.S. pharmaceutical distributors, and patients have access to Rhopressa® through pharmacies across the United States. We expect preferred formulary coverage for the majority of commercial plans by the end of 2018, and preferred formulary coverage for the majority of Medicare Part D plans commencing in 2019. We have already obtained coverage in some commercial and Medicare Part D plans and are in the process of increasing those levels of coverage. In the glaucoma market in the United States, approximately half of the volumes are covered under commercial plans and half under Medicare Part D. Medicare Part D coverage would normally commence for Rhopressa®, as with other new products, ourselves in North American markets. If approved, we plan to buildon January 1, 2019. However, there have been early acceptances of Rhopressa® onto certain Medicare Part D plans, commencing as early as June 1, 2018. We hired a commercial team that will includeincludes approximately 100 sales representatives to target approximately 10,000 high prescribing eye-care14,000 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 RoclatanTM, if approved.
We are also enhancingseek to enhance our longer-term commercial potential by identifying and advancing additional product candidates and drug delivery technologies, includingcandidates. This may be accomplished through our internal discovery efforts, andour entry into potential research collaborations or in-licensing arrangements or acquisitionsour acquisition of additional ophthalmic products or technologies or product candidates that would complement our current product portfolio. Our collaboration with DSM, a global science-based company headquartered in the Netherlands, as further discussed below, through which we obtained access to their bio-erodible polymer technology, is an example of this, as is our acquisition of assets from Envisia Therapeutics Inc. (“Envisia”), designed to advance our progress in developing potential future product candidates to treat retinal diseases.
Our strategy also includes developing our business outside of North America, including obtaining regulatory approval in Europe and Japan on our own for Rhopressa® and RoclatanTM. If we obtain regulatory approval, we currently expect to commercialize Rhopressa® and RoclatanTM in Europe on our product candidates. own, and likely partner for commercialization in Japan.
In 2015,January 2017, we revisedannounced that we are building a new manufacturing plant in Athlone, Ireland. This will be our corporate structurefirst manufacturing plant, which is expected to align withproduce commercial supplies of Rhopressa® and, if approved, RoclatanTM. Commercial supply from our business strategy outsideIreland manufacturing plant is expected to be available by 2020. Our current contract manufacturer started producing commercial supply of North America by establishing Aerie Pharmaceuticals Limited,Rhopressa® in 2017. We are also in the process of adding a wholly-owned subsidiary (“Aerie Limited”), and Aerie Pharmaceuticals Ireland Limited, a wholly-owned subsidiary (“Aerie Ireland Limited”). We assigned the beneficial rights to our non-U.S. and non-Canadian intellectual property for our lead product candidates to Aerie Limited (the “IP Assignment”). As part of the IP Assignment, we and Aerie Limited entered into a research and development cost sharing agreement pursuant tosecond contract manufacturer, which we and Aerie Limited will shareexpect may produce commercial supply by as early as the costsend of 2018. We expect to continue to use product sourced from our current contract manufacturers when the development of intellectual property and Aerie Limited and Aerie Ireland Limited entered into a license arrangement pursuant to which Aerie Ireland Limited will develop and commercialize the beneficial rights of the intellectual property assigned as part of the IP Assignment. In 2016, we assigned the beneficial rights to certain of our intellectual property in the U.S. and Canada to Aerie Distribution, Inc., a wholly-owned subsidiary (“Aerie Distribution”), and amended and restated the research and development cost sharing agreement to transfer our rights and obligations under the agreement to Aerie Distribution.
Product Candidate Overview
Our two advanced stage product candidates are designed to lower intraocular pressure (“IOP”) in patients with open-angle glaucoma or ocular hypertension. Both product candidates are taken once-daily and have shown in preclinical and clinical trials to be effective in lowering IOP, with novel mechanisms of action (“MOAs”) and a positive safety profile.plant is operational.
We own the worldwide rights to all indications for our current Aerie product candidates.Rhopressa® and RoclatanTM. We have patent protection for Rhopressa® and RoclatanTM in the United States through at least 2030 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. We have patent protection for our current product candidates, RhopressaTM
Product and Roclatan™, in the United States through at least 2030.Product Candidate Overview
RhopressaTM®
Our first, our only current product candidate, RhopressaTMis a novel once-daily eye drop designed to lower IOP in patients with glaucoma or ocular hypertension. We are developing RhopressaTM asapproved by the FDA, 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, RhopressaTM will represent the first new MOAs for lowering IOPreducing intraocular pressure (“IOP”) in patients with glaucoma in over 20 years. Based on preclinical studies and clinical data to date, we expectRhopressa® has demonstrated that it reduces IOP through Rho

kinase (“ROCK”) inhibition, its mechanism of action (“MOA”) by which Rhopressa® increases the outflow of aqueous humor through the trabecular meshwork (“TM”), which accounts for approximately 80% of fluid drainage from a healthy eye. Our late-stage pipeline consists of RoclatanTM, if approved, willa single-drop fixed-dose combination of Rhopressa® and latanoprost, which reduces IOP through the same MOA as Rhopressa®, along with a second MOA that utilizes the ability of latanoprost to increase the outflow of aqueous humor through the uveoscleral pathway, the eye’s secondary drain. In a recent “Day 74” letter from the FDA, the RoclatanTM Prescription Drug User Fee Act (“PDUFA”) goal date was set for March 14, 2019. Both Rhopressa® and RoclatanTM are taken once-daily in the evening and have shown in preclinical and clinical trials to be effective in reducing IOP, with a 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. Rhopressa® received approval from the potentialFDA on December 18, 2017, two months earlier than the scheduled PDUFA date of February 28, 2018. The active ingredient in Rhopressa®, netarsudil, is a ROCK inhibitor. In practice, early indications point to healthcare professionals positioning Rhopressa® as concomitant therapy to prostaglandins or non-PGA (prostaglandin analog) medications when additional IOP reduction is desired. Based on this positioning, we believe Rhopressa® may primarily compete with non-prostaglandin analoguenon-PGA products, as a preferred adjunctive therapy to prostaglandin analogues (“PGAs”), due to its targeting of the diseased tissue known as the trabecular meshwork (“TM”),TM, its demonstrated IOP-lowering ability to reduce IOP at consistent levels across tested baselines, withits preferred once-daily dosing its potential synergistic effect with PGA

relative to currently marketed non-PGA products and its lack of drug-related serious or systemic adverse events.safety profile. Adjunctive therapies currently represent approximatelynearly one-half of the entire glaucoma therapyprescription market in the United States, according to IMS. In addition, if approved, weIQVIA (formerly known as IMS Health). We believe that RhopressaTM® may also potentially 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. Also, in a 24-hour, 12-patient pilot study comparing Rhopressa™ efficacy to that of placebo, Rhopressa™ demonstrated similar levels of IOP lowering during nocturnal and diurnal periods. 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 resubmittedRocket 4, one of our NDA with the FDAPhase 3 registration trials for RhopressaTMon February 28, 2017. The PDUFA goal date for the completion of the FDA’s review of the RhopressaTM® NDA is set for February 28, 2018. This date reflects a standard 12-month review period. The notification we received from the FDA also indicated that the FDA is currently planning to hold an advisory committee to discuss the NDA. Our initial submission, announced in September 2016, was withdrawn as a result of a contract manufacturer of our drug product not being prepared for pre-approval inspection by the FDA.
The NDA submission included our second Phase 3 registration trial for RhopressaTM, named “Rocket 2,” as the pivotal clinical trial and our initial Phase 3 registration trial, named “Rocket 1,” as supportive in nature. Our Rocket 2 trial achieved its primary efficacy endpoint of demonstrating non-inferiority of RhopressaTM compared to timolol. In addition, the 12-month safety data from this registration trial also confirmed a positive safety profile for the drug and demonstrated a consistent IOP-lowering effect throughout the 12-month period at the specified measurement time points. We also included as supportive data the 90-day efficacy results of Rocket 4 and Mercury 1, each as further discussed below, with the NDA submission for RhopressaTM.
Our fourth Phase 3 registration trial for RhopressaTM, named “Rocket 4,” in the U.S., was designed to generate adequate six-month safety data for European regulatory approval, for which we expect to file in the second half of 2018. The six-monthalong with efficacy and safety and efficacy data were largely consistent with observations in thefrom our other RhopressaTM Phase 3 registration trials and the 90-day efficacy results achieved the primary efficacy endpoint of demonstrating non-inferiority of RhopressaTM compared to timolol. A third Phase 3 registration trial for RhopressaTM, named “Rocket 3,” was a small 12-month safety-only study in Canada that was not necessary for the NDA submission and for which we had discontinued enrollment.
The RhopressaTM Phase 3 registration trial results have shown no drug-related serious adverse events or drug related systemic adverse events, with the most common adverse event reported being conjunctival hyperemia, or eye redness, with incidence rates of approximately 50% across all Phase 3 registration trials for RhopressaTM®, Rocket 1 and Rocket 2. We expect to file a marketing authorization application (“MAA”) for Rhopressa® with the majorityEuropean Medicines Agency (“EMA”) by the end of 2018. We also completed a Phase 1 clinical trial and commenced a Phase 2 clinical trial in the United States, which was reported as mild.are designed to support meeting the requirements of Japan’s Pharmaceuticals and Medical Devices Agency for potential regulatory submission of Rhopressa® in Japan. These clinical trials have included Japanese and Japanese-American subjects. We are also planning to initiate an additional Phase 2 clinical trial on Japanese patients in Japan to support subsequent Phase 3 registration trials that are expected to be conducted in Japan.
RoclatanTM 
Our secondadvanced-stage product candidate, is once daily RoclatanTM, is a once-daily fixed-dose combination of RhopressaTM® and latanoprost. We believe, based on our preclinical studies and clinical trials to date,data, that Roclatan™, if approved, will be the only glaucoma product that covers the full spectrum of currently known IOP-lowering MOAs, giving itRoclatanTM has the potential to provide a greater IOP-loweringIOP-reducing effect than any currently marketed glaucoma product.medication. Therefore, we believe that Roclatan™RoclatanTM, if approved, 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 use of currently available therapies.
We recentlysubmitted a New Drug Application (“NDA”) for RoclatanTM to the FDA in May 2018 under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, which provides for an abbreviated approval pathway, since RoclatanTM is a fixed dose combination of two FDA-approved drugs in the United States. On July 23, 2018, we 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. This was communicated by the FDA via a “Day 74” letter, which also indicated that the application is sufficiently complete to permit a substantive review and that the FDA had not identified any potential review issues. The “Day 74” letter did not mention the need for an advisory committee.
We have completed two Phase 3 registration trials for RoclatanTM. The first Phase 3 registration trial for Roclatan™RoclatanTM, named “MercuryMercury 1, was a 12-month safety trial with a 90-day efficacy readout. Mercury 1 achieved its primary efficacy endpoint of demonstrating statistical superiority of Roclatan™RoclatanTM to each of its components. Thecomponents, including Rhopressa® and the market-leading PGA, latanoprost, and the safety and tolerability results for RoclatanTM from the 90-day efficacy period of Mercury 1 showed no drug-related serious adverse events or drug related systemic adverse events. On July 19, 2017, we announced the results of the Mercury 1 12-month safety study,results, noting the safety results for RoclatanTM for the 12-month period were consistent with those observed for the 90-day efficacy period.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.
The second Phase 3 registration trial for Roclatan™RoclatanTM, named “MercuryMercury 2, was a 90-day efficacy and safety trial also designed to demonstrate statistical superiority of Roclatan™RoclatanTM to each of its components. 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. Both Mercury 1 and Mercury 2 achieved their 90-day primary efficacy endpoints of demonstrating statistical superiority over each of its components, including Rhopressa

TM and market-leading PGA, latanoprost, at all measured time points. The superiority of RoclatanTM over each of its components was consistentlyat all measured time points in the rangepatients with maximum baseline IOPs of 1above 20 mmHg to 3 mmHg (millimeters of mercury). We are permitted to submit the Roclatanbelow 36 mmHg.TM NDA while the RhopressaTM NDA is still being reviewed by the FDA. We expect to submit an NDA for Roclatan™ in the first half of 2018, which may be prior to obtaining approval for RhopressaTM.

Mercury 1 and Mercury 2 will also be used for European approval of RoclatanTM, and we plan to initiateinitiated a third Phase 3 registration trial for RoclatanTM, named “MercuryMercury 3, in Europe induring the third quarter of 2017. Mercury 3, a six-month safety trial, is designed to compare Roclatan™RoclatanTM to Ganfort®, a fixed-dose combination product of bimatoprost, a PGA, and timolol marketed in Europe, which ifEurope. If successful, Mercury 3 is expected to improve our commercialization prospects in that region.
In additionEurope. We currently expect to our continued use of product sourced from our current contract manufacturer basedread out topline 90-day efficacy data for the trial in 2019 and to submit an MAA with the U.S., in January 2017, we announced that we are building a new manufacturing plant in Athlone, Ireland. This will be our first manufacturing plant, expected to produce commercial supplies of our current product candidates, RhopressaTMandEMA for RoclatanTM. If we obtain regulatory approval, commercial product supply from the plant is expected to be available by 2020. We are also in the process of adding a second contract manufacturer. thereafter.
Pipeline Opportunities
Our stated objective is to build a major ophthalmic pharmaceutical company. In addition to our primary product candidates, RhopressaTM and Roclatan™, we continue to explore the impact of RhopressaTM on the diseased TM. We have issued several research updates on preclinical results demonstrating that RhopressaTM may have the potential for disease modification, including stopping and potentially reversing fibrosis in the TM, and also increasing perfusion in the trabecular outflow pathway thus increasing both drainage and the delivery of nutrients to the diseased tissue. We are also conducting ongoing research to evaluate injectable sustained release formulation technologies with the potential capability of delivering the active metabolite in RhopressaTM internally in the eye over several months for the treatment of glaucoma.
We are also evaluating possible uses of our existing proprietary portfolio of Rho kinaseROCK inhibitors beyond glaucoma.glaucoma and ophthalmology. Our owned preclinical small molecule, AR-13154,AR-13503, has demonstrated the potential for the treatment of diabetic retinopathy and wet age-related macular degeneration (“AMD”) by inhibiting Rho kinaseROCK and Protein kinase C andC. 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 (“anti-VEGF”) product. When used in combination with the market-leading anti-VEGF product, and evenAR-13503 produced greater lesion size reduction in combination withthan the current market-leading wet AMD anti-VEGF product. Further, in our preclinical studies, we have seen a promising potential of this molecule to reduce neovascularizationproduct alone in a model of proliferative diabetic retinopathy. Pending additional studies, the active metabolite of AR-13154 and related molecules may have the potential to provide an entirely new mechanism and pathway to treat wet AMD and other diseases of the retina, such as diabetic retinopathy. This molecule has not yet been tested in humans in a clinical trial setting. Pending additional studies, AR-13503 may have the potential to provide an entirely new mechanism and pathway to treat diabetic retinopathy, wet AMD and related diseases of the retina, such as diabetic macular edema (“DME”). We expect to submit an Investigational New Drug application (“IND”) for AR-13503 in early 2019. Since AR-13503 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.
To that end, on July 31, 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. 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. On August 1, 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.
Further, on October 4, 2017, we acquired the rights to use PRINT® technology in ophthalmology and certain other assets from Envisia. The PRINT® technology is a proprietary system 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 DME that also utilizes the PRINT® technology, which we refer to as AR-1105. We expect to submit an IND for AR-1105 near the end of 2018. We will also focus on using PRINT® to manufacture injectable implants containing AR-13503, potentially in conjunction with the bio-erodible polymer from DSM.
We may continue to enter into research collaboration arrangements, license, acquire or develop additional product candidates and technologies to broaden our presence in ophthalmology, and 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 focused on the evaluation of technologies for the delivery ofscreening our owned molecules to the frontlibrary of ROCK inhibitors for indications beyond ophthalmology, considering third-party studies and back of the eye over sustained periods. For example, we recently announced that wetrials have entered into a collaborative research, development and licensing agreement with DSM, a global science-based company headquartereddemonstrated potential for ROCK inhibition in the Netherlands. The research collaboration agreement includes an option to license DSM’s bioerodible polymer implant technology for evaluating its application to the delivery oftreating certain Aerie compounds,disease categories. We are initially focused on retinal diseases.exploring potential opportunities for our molecules in pulmonary health, dermatology and cancers.
Financial Overview
Our cash, cash equivalents and investments totaled $307.9$286.1 million as of June 30, 20172018. We believe our cash, cash equivalents and investments balances are currently expectedadequate to provide sufficient resources for our current ongoing needs.needs, though there may be need for additional financing activity as we continue to grow, such as the potential use of the credit facility we entered into in July 2018. No amounts were drawn at the closing of such credit facility. See “—OperatingLiquidity and Capital Requirements.”

If we do not successfully commercialize any of our current product candidates, we may be unable to generate product revenue or achieve profitability.additional information.
We have incurred net losses since our inception in June 2005. OurHistorically, our operations to date havehad primarily been limited to research and development and raising capital. As of June 30, 2017,2018, we had an accumulated deficit of $370.8$559.6 million. We

recorded net losses of $55.0 million and $95.7 million for the three and six months ended June 30, 2018, respectively. We recorded net losses of $28.4 million and $54.2 million for the three and six months ended June 30, 2017, respectively. We recorded net losses of $23.2 million and $45.9 million for the three and six months ended June 30, 2016, respectively. We anticipate that a substantial portion of our2017. Our capital resources and business efforts in the foreseeable future will beare largely focused on completingactivities relating to the developmentcommercialization of Rhopressa®, advancing our product pipeline, international expansion and obtaining regulatory approval and preparing for potential commercialization and manufacturingconstruction of our product candidates.

As a result, wemanufacturing facility in Athlone, Ireland. We expect to continue to incur significant operating losses until such a time when one or more of our product candidates areproducts is commercially successful, if at all. In 2017,If we expectdo not successfully commercialize Rhopressa®, or RoclatanTMor any future product candidates, if approved, we may be unable to generate product revenue or achieve profitability. We may be required to draw down on the credit facility we entered into in July 2018, or to obtain further funding through 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 acceptable terms, we may be forced to delay, reduce or eliminate our research and development programs or commercialization or manufacturing efforts.
Product Revenues, Net
As a result of the commercial launch of Rhopressa® in the United States in late April 2018, we commenced generating product revenues from sales of Rhopressa® during the three months ended June 30, 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, 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 buying and payment patterns. 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.
We will not generate any revenue from RoclatanTM or any future product candidates unless and until we obtain regulatory approval and commercialize such 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 selling, general and administrative expensesexpenses. Cost of goods sold in 2018 will be favorably impacted by sales of Rhopressa® inventory that was expensed prior to FDA approval; however, we do not expect the impact to be higher than in 2016 as we prepare for potential commercialization of our product candidates, including increases in employee-related costs and in expenses and costs related to expanded infrastructure, pre-launch commercial operations and manufacturing activities. Additionally, we anticipate that our clinical expenses will be lower in 2017 as compared to 2016 as we complete clinical trials and pursue regulatory approval for our product candidates in the U.S.material.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of salaries, benefits and stock-based compensation for all officers and employees in general management, sales and marketing, manufacturing, finance, and administration. Other significant expenses include pre-approval commercial-related manufacturing costs, including building commercial inventory in preparation for the potential launch of RhopressaTM, pre-launch sales and marketing planning activities, facilities expenses and professional fees for audit, tax, legal and other services.
We expect that our selling, general and administrative expenses will increase withbe higher in 2018 as compared to 2017 due to the continued advancement of our product candidates as we preparecommercialization efforts for potential commercialization. We expect these increases will likely be associated withRhopressa®, including the hiring of sales representatives and additional employees in areas such asfocused on sales, and marketing and medical affairs, along with increased levels of manufacturing activity and overhead expenses associated with the growth of our employee base.activities.
Research and Development Expenses
The following table showsWe expense research and development 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, including employee-related expenses for research and development personnel.
Excluding the $24.8 million of expense recognized in 2017 related to the Envisia asset acquisition, we expect that our research and development (“R&D”) expenses by product candidatewill increase in 2018 as compared to 2017 due to clinical trial activities for both Rhopressa® and type of activityRoclatanTM for the three and six months ended June 30, 2017 and 2016:

Other Income (Expense), Net
Other income (expense) primarily includes interest income, interest expense, and foreign exchange gains and losses. OtherInterest income primarily consists of interest earned on our cash, and cash equivalents and investments, and amortization or accretion of discounts and premiums on our investments. Interest expense consists of interest expense under the 2014 Convertible Notes,

including the amortization of debt discounts and issuance costs. 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.
In July 2018, the 2014 Convertible Notes were fully converted into shares of Aerie common stock. See Note 13 to our condensed consolidated financial statements included 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 condensed 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, net revenue, 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, accrued expenses, fair value measurements, acquisitions and stock-based compensation and operating expense accruals.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.
OurOther than the application of revenue recognition policies and estimates as described below, our critical accounting policies and the methodologies and assumptions we apply under themsignificant estimates have not materially changed since the date we filed our 20162017 Form 10-K. For more information on our critical accounting policies and estimates, refer to our 20162017 Form 10-K.
Revenue Recognition
We recognize revenue when our customers obtain control of our 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 three and six months ended June 30, 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. We have already obtained coverage in some commercial and Medicare Part D plans and are in the process of increasing those levels of coverage. In the glaucoma market in the United States, approximately half of the volumes are covered under commercial plans and half under Medicare Part D. Medicare Part D coverage would normally commence for Rhopressa®, as with other new products, on January 1, 2019. However, there have been early acceptances of Rhopressa® onto certain Medicare Part D plans, commencing as early as June 1, 2018.
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 based on the expected method of settlement. Amounts billed or invoiced are included in accounts receivable, net on the condensed consolidated balance sheet. We did not have any contract assets (unbilled receivables) at June 30, 2018, as customer invoicing generally occurs before or at the time of revenue recognition. We did not have any contract liabilities at June 30, 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 three months ended June 30, 2018, three Distributors accounted for 34%, 33% and 30% 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 variable consideration. Variable consideration consists of estimates relating to (i) trade discounts and allowances, such as discounts for prompt payment and Distributor fees, (ii) estimated rebates, chargebacks and other discounts payable to Third-party Payers 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. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, 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.

Cost of goods sold
Cost of goods sold was $0.1 million for the six months ended June 30, 2018. Our gross margin percentage of 98% was favorably impacted during the six months ended June 30, 2018 by sales of Rhopressa® with certain materials produced prior to FDA approval and therefore expensed in prior periods. If inventory sold during the six months ended June 30, 2018 was valued at cost, our gross margin for the period then ended would have been 97%.

During the six months ended June 30, 2016, our research2017. This increase is primarily comprised of an increase of $5.7 million of employee-related expenses, including stock-based compensation, and an increase of $1.7 million related to preclinical programs, partially offset by a $2.2 million decrease in expenses related to RoclatanTM. Research and development activity was primarily associated with Phase 3 registration trialsexpenses for RhopressaRoclatanTM and Roclatan. The Phase 3 registration trials for both Rhopressa and Roclatan have been completed for purposes of applying for FDA approval in the U.S. As such, direct clinical and non-clinical costs for Rhopressa and Roclatandecreased by $5.6totaled $4.2 million and $1.0$6.4 million respectively, for the six months ended June 30, 2018 and 2017, respectively.

Liquidity and Capital Resources
Since our inception, we have funded operations primarily through the sale of equity securities 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 until such a time when one or more of our product candidates areproducts is commercially successful, if at all. We received FDA approval for Rhopressa® on December 18, 2017 and launched Rhopressa® in the United States in late April 2018. As a result, we commenced generating product revenues related to sales of Rhopressa® in the second quarter of 2018.
Sources of Liquidity
Prior to our IPO,During the six months ended June 30, 2018, we raised net cash proceeds of $78.6issued approximately 2.3 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 preferredour common 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, fees and expenses.
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$136.4 million, after deducting discounts and certain expenses of $2.1 million, and
10.8 million shares of our common stock through June 30, 2017, for which we received net proceeds of approximately $339.5 million, after deducting commissions and other fees and expenses. This includes $195.9approximately $62.3 million raisedof net proceeds from our “at-the-market” sales agreements,agreement (“ATM”) and approximately $74.1 million of which $49.3 million in net proceeds was raised during the six months ended June 30, 2017.

The increase in cash used in operating activities during the six months ended June 30, 20172018 as compared to the six months ended June 30, 20162017 was primarily due to the expansion of our employee base, andas well as an increase in cash used for commercial operations and manufacturing activities in preparation for the launch of RhopressaTM®, assuming FDA approval. This is partially offset by a reduction in expenditures for clinical trials in 2017 compared to 2016.

Operating Capital Requirements
We expect to incur ongoing operating losses until such a time when ourRhopressa® orRoclatanTM or any other product, candidatesif approved in the future, are commercially successful, if at all.
Our principal liquidity requirements are for: working capital; future increased operational expenses; pre-commercialization planningcommercialization and manufacturing activities; expenses associated with developing our pipeline opportunities, including pursuing strategic growth opportunities; costs associated with executing our international expansion strategy, to expand intoincluding clinical and potential commercialization activities in Europe and Japan; contractual obligations; capital expenditures, including completing our manufacturing plant in Ireland; and debt service payments.
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. Estimated project-wide equipment, construction and otherCapital expenditures related project costs are expected to totalthe manufacturing plant totaled approximately $39$21.2 million (excluding ongoing labor-related and lease expenses), of which approximately $16 million is expected to be spent in 2017.during the six months ended June 30, 2018. 

We believe that our cash, and cash equivalents and investments as of June 30, 20172018 will provide sufficient resources to support our commercial activities for Rhopressa®through at least the next twelve months and to support the expected approval and planned commercialization of RhopressaTM andRoclatanTMin the U.S.United States. 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 first two years of payments on any drawn amounts will be on an interest-only basis. We do not currently intend on drawing down on the credit facility but may do so if and as needed.
Our future funding requirements will depend on many factors, including, but not limited to the following:
costs of commercialization activities for Rhopressa® and RoclatanTM and any future product candidates, if approved, including the costs and timing of establishing product sales, marketing, manufacturing and distribution capabilities, and related product sales performance;
commercial performance of Rhopressa® and RoclatanTM or any future product candidates, if approved;
costs, timing and outcome of seeking regulatory approval;
the costs of commercialization activities for our product candidates, if we receive regulatory approval, including the costs and timing of establishing product sales, marketing, manufacturing and distribution capabilities;
the commercial performance of our future product candidates;
timing and costs of our ongoing and future preclinical studies and clinical trials for our product candidates outside of the U.S.;and preclinical studies;
costs to complete our new manufacturing plant in Ireland;

costs of any follow-on development or products, including the exploration and/or development of any additional indications or additional opportunities for new ophthalmic products,product candidates, delivery alternatives and new therapeutic areas;
costs of any new business strategies;
costs of operating as a public company, including legal, compliance, accounting and investor relations expenses;activities;
terms and timing of any acquisitions, collaborations, licensing, consulting or other arrangements;
costs related to our credit facility; and
filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against intellectual property related claims.
We based our projections on assumptions that may prove to be incorrect or unreliable or may change due to circumstances beyond our control, and as a result, we may consume our available capital resources earlier than we originally projected. We may need to obtain additional financing to fund our future operations or we may decide, based on various factors, that additional financings are desirable. If such funding is required, we cannot guarantee that it will be available to us on favorable terms, if at all.
Outstanding Indebtedness
As of June 30, 2017,2018, our total indebtedness consisted of our $125.0 million aggregate principal amount of 2014 Convertible Notes, which are due in September 2021.Notes.

Off-Balance Sheet Arrangements
We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements as defined under SEC rules.None.

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 will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Our independent registered public accounting firm will not be required 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.
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 $1.07 billion or more; (iii) the date on which we have, during the previous three-year period, issued more than $1 billion in non-convertible debt securities; 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.
Since the market value of our common stock held by non-affiliates exceeded $700 million as of June 30, 2017, as of the year ending December 31, 2017, we will cease to be an “emerging growth company.” As a result, beginning with our Annual Report on Form 10-K for the year ending December 31, 2017, we will be subject to Section 404(b) of the Sarbanes-Oxley Act, which requires that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting.
Recent Accounting Pronouncements
For a discussion of recently issued accounting standards, see Note 2 to our condensed consolidated financial statements included in this report.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
We have market risk exposure to interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. Our cash and cash equivalents as of June 30, 2017,2018 totaled $242.7 million and consisted of cash and money market funds.$270.6 million. Our investments totaled $65.3$15.5 million as of June 30, 2018 and consisted of commercial paper and corporate bonds. As of December 31, 2017, our cash and cash equivalents totaled $197.6 million. Our investments totaled $52.1 million as of December 31, 2017 and consisted of commercial paper and corporate bonds. We had cash, cash equivalents and investments of $233.7 million as of December 31, 2016. Given the short-term nature of our cash, cash equivalents and investments and our investment policy, 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 in any hedging activities against changes in interest rates. The 2014 Convertible Notes carry a fixed interest rate and, as such, are not subject to interest rate risk.
Aerie willWe 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 currently do not have any derivative instruments or a foreign currency hedging program. To date and during the six months ended June 30, 2017,2018, foreign currency exposure and foreign currency financial instruments have not been material.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and 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 June 30, 2017,2018, the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file and 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.
Changes in Internal Control Over Financial Reporting
As a result of our commercial launch of Rhopressa® in the United States during the quarter ended June 30, 2018, we implemented processes and internal controls to record product revenues, net, cost of goods sold and inventory. The implementation of these processes resulted in changes to our internal controls over financial reporting, which we believe were material. There have beenwere no significantother changes in our internal controlcontrols over financial reporting during our most recent fiscal quarter that hashave materially affected, or isare reasonably likely to materially affect, our internal control over financial reporting.


PART II. OTHER INFORMATION
Item 1. Legal Proceedings
We may periodically become subject to legal proceedings and claims arising in connection with our business. WeExcept as previously disclosed for matters which have now concluded, we are not a party to any known litigation, are not aware of any unasserted claims and do not have contingency reserves established for any litigation liabilities.
Item 1A. Risk Factors
You should consider carefully the risks described below and set forth under “Risk Factors” in our 20162017 Form 10-K, and other documents that we have filed or furnished with the SEC.
As of December 31, 2017, we will There have been no longer be an “emerging growth company” and, as a result, we will havematerial changes to comply with increased disclosure and governance requirements.
As a result of the significant increase in our market capitalization as of June 30, 2017, we will cease to be an “emerging growth company” as defined in the JOBS Act as of December 31, 2017. We will, as of December 31, 2017, be a large accelerated filer and, as such, will be subject to certain requirements that apply to other public companies but did not previously apply to us due to our status as an emerging growth company. These requirements include:
the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting;
the requirement to provide detailed compensation discussion and analysis in proxy statements and reports filed under the Exchange Act; and
the “say on pay” provisions (requiring a non-binding stockholder vote to approve compensation 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.
Beginning with our Annual Report on Form 10-K for the year ending December 31, 2017, we will be subject to Section 404(b) of the Sarbanes-Oxley Act, which requires that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting. Compliance with Section 404 will be expensive and time consuming for management and could result in the detection of internal control deficiencies of which we are currently unaware. Moreover, if we have a material weakness in 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 our independent registered public accounting firm may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting, which could harm our operating results, cause investors to lose confidence in our reported financial information and cause the trading price of our common stock to fall. We expect that the loss of “emerging growth company” status and compliance with the additional requirements will substantially increase our legal and financial compliance costs and make some activities more time consuming and costly.these risk factors.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
Unregistered Sales of Equity Securities
None.
Use of Proceeds from Registered Securities
On November 3, 2014, we filed a shelf registration statement on Form S-3 (the “2014 Registration Statement”) that permitted the offering, issuance and sale by us of up to a maximum aggregate offering price of $150.0 million of our common stock and permits sales of common stock by certain selling stockholders.

On September 15, 2016, we filed a shelf registration statement on Form S-3 (Registration No. 333-213643), which was effective on September 15, 2016. The shelf registration statement permits the offering, issuance and sale by us of our common stock. In addition, on May 25, 2017, we filed a prospectus supplement to the base prospectus dated September 15, 2016 (the “2017 Prospectus Supplement”). The prospectus supplement permits the offering, issuance and sale by us of up to a maximum aggregate offering price of $50.0 million of our common stock.
From November 10, 2014 through June 30, 2017, we issued and sold 6,840,570 shares of common stock under our “at-the-market” sales agreements, of which 906,858 shares were issued and sold during the six months ended June 30, 2017, and received net proceeds of approximately $195.9 million, of which $49.3 million were received during the six months ended June 30, 2017, in each case, after deducting commissions and other fees and expenses. Sales under the “at-the-market” sales agreements were made pursuant to the 2014 Registration Statement, the prospectus supplement (the “2016 Prospectus Supplement”), dated September 15, 2016, to the base prospectus dated September 15, 2016 and the 2017 Prospectus Supplement. As of June 30, 2017, no shares remain available for issuance under the 2014 Registration Statement, the 2016 Prospectus Supplement or the 2017 Prospectus Supplement.
Any remaining net proceeds from these sales are held as cash deposits and in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.
