Our commitment to bioprocessing is helping to set new standards for the way our customers. Our mission iscustomers manufacture biologic drugs, including monoclonal antibodies (“mAb”), recombinant proteins, vaccines and gene therapies. We are dedicated to inspireinspiring advances in bioprocessing as a trusted partner in the production of biologic drugs that improve human health worldwide. Focused

We currently operate as one bioprocessing business, with a comprehensive suite of products to serve both upstream and downstream processes in biologic drug manufacturing. Building on cost and process efficiencies,over 35 years of industry expertise, we deliver innovative technologies that help set new standards in the way biologic drugs are manufactured. We develop and markethave developed a broad range of high-value products and flexible solutions that address critical steps in the production of biologic drugs – principally antibody-based therapeutics, recombinant proteins and vaccines – while ensuring that the highest drug quality and safety standards are upheld.

Since our strategic decision in 2012 to focus fully on building our bioprocessing business, we have expanded and diversified product portfolio that reflects our portfolio beyondcommitment to build abest-in-class bioprocessing technology company with a world-class direct sales and commercial organization.

We are committed to capitalizing on growth opportunities and maximizing the value of our legacy Protein A affinity ligands business to include a number of technology leading bioprocessing products that we sell direct to biopharmaceutical companiesproduct platform through both organic growth initiatives (internal innovation and CDMOs (contract developmentcommercial leverage) and manufacturing organizations) worldwide. targeted acquisitions.

Our dedicated team of professionals has substantial experience in biomanufacturing and works proactively with industry leaders and customers to develop innovative solutions that address pressure points in the bioproduction process.Products

Our bioprocessing business is comprised of three main product lines – Chromatography, Filtration and Proteins.

Direct-to-Customer Products (Chromatography and Filtration)

Since 2012, we have significantly expanded ourdirect-to-customer presence through our Chromatography and Filtration product lines, which include differentiated products drive process efficiency, cost and yield improvements. In upstream processes,systems. We have diversified and grown our XCell™ ATF filtration devicesdirect-to-customer product offering through internal innovation and protein cell culture supplements are used in clinicalthrough disciplined, accretive acquisitions of assets or businesses that leverage existing product lines and/or expand our customer and commercial-stage manufacturing to improve biologic drug yields. In downstream processes,geographic scope.

To support our Protein A ligands are a critical component of Protein A resins used to purify over 50 antibody-based drugs on the market and more than 350 in clinical development. Also in downstream processes,sales goals for our OPUS pre-packed chromatography columns (PPCs) are used in the purification of clinical-stage biologics, and our Sius™ tangential flow filtration (“TFF”) cassettes are used to concentrate clinical and commercial-stage biologic drugs.

We manufacture and supply Protein A ligands through long-term agreements with major life sciences companies such as GE Healthcare and MilliporeSigma, who in turn produce and sell Protein A resins to end users (biopharmaceutical companies and CDMOs). We manufacture and supply our cell culture supplements through a distribution agreement with MilliporeSigma.

We market our chromatography and filtrationdirect-to-consumer products, globally through a direct commercial organization in the United States and Europe with a combination of direct sales and distributors in Asia. Since 2014, we have invested in expanding our global commercial organization adding 30 sales, marketing, product management, service and applications personnel to form a 37-person commercial team.organization. Our commercial and R&Dresearch and development teams have a track record of successfully launchingwork to effectively launch new products and applications, as well as buildingbuild new markets for acquired technologies. For example, since acquiring the XCell ATF business in 2014, we have rapidly expanded its market penetration through increased customer interaction, new products and expanded applicationstechnologies that increase flexibility and convenience while streamlining biomanufacturing workflow for our customers.

Our portfolio of bioprocessing products has expanded from our legacy Protein A line since 2011 through strategic acquisitions and internal product development. We have focused on building a portfolio of technology-leading products that we sell directly In addition, to end users. In 2016, we added the Sius TFF filtration line through our

purchase of TangenX Technology Corporation (“TangenX” and the “TangenX Acquisition”), and we added a lab-scale pre-packed chromatography column line through our purchase of Atoll GmbH (the “Atoll Acquisition”). In 2014, we acquired the XCell ATF filtration line from Refine Technologies LLC (the “Refine Acquisition”). In 2011, we added to our Protein A ligands business and added cell culture growth factors through our acquisition of Novozymes Biopharma Sweden AG (the “Novozymes Acquisition”). Internally, we develop and market our process-scale OPUS pre-packed chromatography columns. Also through internal innovation, we have extended both our OPUS and XCell ATF product lines, to include more size options and technology features to benefit our customers. For example in 2016 we introduced a resin recovery feature on our largest OPUS columns (OPUS R) and we launched a single-use (disposable) alternative to our stainless steel XCell ATF Systems.

Many of our products are early in their adoption cycle, and together with the expansion of our commercial organization and strategic acquisitions, have contributed to product revenue expansion from $41.8 million in 2012, to $104.5 million in 2016. While all product franchises have grown, our diversification strategy has resulted in our direct product sales accounting for approximately 52% of our bioprocessing revenue in 2016, compared to approximately 20% in 2012. To meet increased demand for our products, we have increased and continue to increaseinvest in increasing the volume and scale of manufacturing at our two manufacturing facilities in the United States, and Sweden and planGermany.

Chromatography

Our Chromatography product line includes a number of products used in the downstream purification and quality control of biological drugs. The main driver of growth in this portfolio is our lab and process-scale OPUS®pre-packed chromatography (“PPC”) column line.

Our other products include chromatography resins (such as CaptivA®) used in a small number of commercial drug processes and ELISA test kits used by quality control departments to detect and measure the presence of leached Protein A and/or growth factor in the final product.

OPUS®

Our Chromatography product line features PPC columns under our OPUS brand. OPUS columns, which we deliver to our customerspre-packed with their choice of chromatography resin, are single-campaign(“single-use”) disposable columns that replace the use of traditional and more permanent glass columns used in downstream purification processes. By designing OPUS to be a technologically advanced and flexible option for the purification of biologics from process development through clinical-scale and some commercial manufacturing, Repligen has become a leader in the PPC market. The customization andready-to-use nature of our OPUS columns makes them ideal for purification of antibodies, recombinant proteins and vaccines. Biomanufacturers value the time savings, labor and utility cost savings, product consistency and the “plug and play” convenience of OPUS.

We launched our first production-scale OPUS columns in 2012 and have since added larger diameter options such as OPUS 45 and OPUS 60. Early in 2018, we introduced OPUS 80 R, the largest available PPC on the market, for use in late-stage clinical or select commercial purification processes. We have also introduced next-generation features such as a resin recovery port on our larger columns. This allows our customers to reuse the recovered resin in other applications. The unpacking port feature was made available in the first quarter of 2017 on our largest production-scale OPUS columns.

Through our acquisition of Atoll GmbH in 2016, we established a customer-facing center in Europe and expanded our portfolio to include our smaller-scale columns, named OPUS PD, that are used in high-throughput process development screening, viral validation studies and scale down validation of chromatography processes. We maintain a broad and customizable PPC product line to meet our customers’ diverse needs.

Other Chromatography

Also included in our Chromatography portfolio are ELISA kits, which are analytical test kits to detect the presence of proteins and growth factors, and chromatography resins, including our CaptivA® brand. In addition, following our acquisition of Spectrum in 2017, we sell Spectra/Chrom® liquid chromatography products as part of our Chromatography product line.

Filtration

XCell ATF

Our Filtration products offer a number of advantages to manufacturers of biologic drugs at volumes that span from pilot studies to clinical and commercial-scale production. We first established our Filtration product line through our acquisition of XCell Alternating Tangential Flow (“ATF”) assets from Refine Technology (“Refine”) in 2014. XCell ATF systems are used primarily in upstream perfusion, or “continuous manufacturing”, processes.

XCell ATF is a technologically advanced filtration device used in upstream processes to continuously remove cellular metabolic waste products during the course of a fermentation run, freeing healthy cells to continue producing the biologic drug of interest. XCell ATF was designed to both increase the density of cells in a bioreactor and extend the production run. By continuously removing waste products from the fermenter, the XCell ATF System routinely increases cell densities to2- or3-times the levels achieved by standard batch fermentation. As a result, product yield is increased, which improves facility utilization and can reduce the size of a bioreactor required to manufacture a given volume of biologic drug product. This is important to biomanufacturers who seek to maximize output from their existing facilities. XCell ATF Systems are suitable for use in laboratory andscale-up all the way to production bioreactors as large as 2,000 liters.

Through internal innovation, we developed and in 2016 launchedsingle-use formats of the original stainless steel XCell ATF device to address increasing industry demand for“plug-and-play” technology. The XCell ATF device is now available to customers in both its original configuration (steel housing and replaceable filters) in all sizes (2, 4, 6 and 10), and/or as asingle-use device (disposable housing/filter combination) in most sizes (2, 6, and 10). The availability of XCell ATF in asingle-use format eliminates thepre-use workflow associated with autoclaving, leading to an 80% reduction in implementation time. Thesingle-use format also enables our customers to accelerate evaluations of the product with a lower initial overall cost of ownership. Based on strong demand, we have continued to expand thesingle-use XCell ATF offering.

In September 2018, we entered into a collaboration agreement with industry leader Sartorius Stedim Biotech (“SSB”) to integrate our XCell ATF controller technology into SSB’s BIOSTAT® STR large-scale,single-use bioreactors, to create novel perfusion-enabled bioreactors.

SIUS Tangential Flow Filters (TangenX)

In December 2016, we acquired TangenX Technology Corporation (“TangenX”), balancing our upstream XCell ATF offering with a downstream portfolio of flat-sheet tangential flow filters (“TFF”) and cassettes used in downstream biologic drug purification and formulation processes. The TangenX portfolio includes oursingle-use SIUS TFF brand, providing customers with a high-performance,low-cost alternative to reusable TFF cassettes.

TFF is a rapid and efficient method for separation and purification of biomolecules that is widely used in laboratory, process development and process scale applications in biopharmaceutical manufacturing. SIUS is an innovativesingle-use TFF line of cassettes and hardware forlab-scale through large-scale biopharmaceutical manufacturing.Single-use SIUS TFF cassettes with enclosed flat sheet membranes are designed to provide a high performing membrane at significantly lower product and labor costs than reusable TFF products. Each disposable cassette is deliveredpre-sanitized, integrity tested and ready to be equilibrated and used for tangential flow diafiltration and ultrafiltration processing. Use of SIUS TFF cassettes eliminatesnon-value added steps of cleaning and flushing required in reusable TFF products. The cassettes are interchangeable with filter hardware from multiple manufacturers, simplifying customer trial and adoption of SIUS products.

KrosFlo®, ProConnex® (Spectrum Life Sciences LLC)

We acquired Spectrum Life Sciences LLC (“Spectrum”) and its subsidiaries in August 2017 to strengthen our filtration business with the addition of a leading portfolio of hollow-fiber (HF) filters and modules,single-use flow path connectors and TFF filtration systems. Spectrum products are used inbench-top through commercial-scale processes, primarily for the filtration, isolation, purification and concentration of biologics and diagnostic products. Our Spectrum filtration products offer both standard and customized solutions to bioprocessing customers, with particular strength in consumable andsingle-use offerings.

With the addition of Spectrum, we nowin-house manufacture hollow-fiber filters that can be used in our XCell ATF system. In addition, we increased our direct sales presence in Europe and Asia, and we diversified our end markets beyond monoclonal antibodies to include vaccines, recombinant protein and gene therapies.

Our Spectrum filtration brands include the KrosFlo® line of hollow-fiber cartridges and TFF systems, the Spectra/Por® portfolio of laboratory and process dialysis products andPro-Connex®single-use hollow-fiberModule-Bag-Tubing sets.

In 2018, we introduced our KONDUiT device to automate concentration and buffer exchange to be used in conjunction with our hollow fiber or flat sheet TFF filtration products.

OEM Products (Proteins)

Our OEM products are represented by our Protein A affinity ligands, which are a critical component of Protein A chromatography resins used in downstream purification, and cell culture growth factor products, which are a key component of cell culture media used upstream to increase cell density in a bioreactor and improve product yield.

Protein A/Ligands

We are a leading provider of Protein A affinity ligands to life sciences companies. Protein A ligands are an essential “binding” component of Protein A chromatography resins used in the purification of virtually all monoclonal antibody based drugs on the market or in development. We manufacture multiple forms of Protein A ligands under long-term supply agreements with major life sciences companies including GE Healthcare, MilliporeSigma and Purolite Life Sciences (“Purolite”), who in turn sell their Protein A chromatography resins to end users (“mAb manufacturers”). We have two manufacturing capacitysites supporting overall global demand for our Protein A ligands: one in Lund, Sweden and another in Waltham, Massachusetts.

Protein A chromatography resins are considered the industry standard for purification of antibody-based therapeutics due to the ability of the Protein A ligand to very selectively bind to or “capture” antibodies from crude protein mixtures. Protein A resins are packed into the first chromatography column of typically three columns used in a mAb purification process. As a result of Protein A’s high affinity for antibodies, the mAb product is highly purified and concentrated within this first capture step before moving to polishing steps.

In June 2018, we entered into an agreement with Navigo Proteins GmbH (“Navigo”) for the exclusiveco-development of multiple affinity ligands for which Repligen holds commercialization rights. We are manufacturing and have agreed to supply the first of these ligands,NGL-Impact™ A, exclusively to Purolite, who will pair our high-performance ligand with Purolite’s agarose jetting base bead technology used in their Jetted A50 Protein A resin product. We also signed a long-term supply agreement with Purolite forNGL-Impact A and potential additional affinity ligands that may advance from our Navigo collaboration. The Navigo and Purolite agreements are supportive of our strategy to secure and reinforce our Proteins product line.

Growth Factors

Most biopharmaceuticals are produced through an upstream mammalian cell fermentation process. In order to stimulate increased cell growth and maximize overall yield from a bioreactor, manufacturers often add growth factors, such as insulin, to their cell culture fermentation media. As part of the Novozymes Acquisition in 2011, we gained several cell culture growth factor additives. Among those products is LONG®R3 IGF-1, our insulin-like growth factor that has been shown to be up to 100 times more biologically potent than insulin (the industry standard), thereby increasing recombinant protein production in cell culture fermentation applications. LONGR3IGF-1 is sold through a distribution partnership with MilliporeSigma.

Corporate Information

We are a Delaware corporation with global headquarters in Waltham, Massachusetts. We were incorporated in 1981 and became a publicly traded company in 1986. Our common stock is listed on The Nasdaq Global Market

under the symbol “RGEN”. We have over 540 employees and operate globally with offices and manufacturing sites located at our newly acquired manufacturing facilitiesmultiple locations in the United States, Europe and Germany.

Customers use our products to produce initial quantities of drug for clinical studies, then scale-up to larger volumes as the drug progresses to commercial production following regulatory approval. Detailed specifications for a drug’s manufacturing process are included in applications that must be approved by regulators, such as the U.S. Food and Drug Administration (“FDA”) and the European Medicines Agency, throughout the clinical trial process and prior to final commercial approval. As a result, products that become part of the manufacturing specifications of a late-stage clinical or commercial process can be very “sticky” due to the costs and uncertainties associated with displacing them.

Our Market Opportunity

The global biologics drug market iswas estimated to be over $200 billion.billion in 2017. This market includes therapeutic antibodies, recombinant proteins and vaccines. Antibody-based biologics alone accounted for approximately $90over $115 billion of global biopharma revenue and represented a majority of the top 10 best-selling drugs across the pharmaceutical industry in 2016.2017. Industry sources project the biologics market to grow at a rate of8%-10% annually over the next five years, driven by strength in the monoclonal antibody (mAb)mAb class of biologics, as evidenced by the rate of new approvals, expanded labels for marketed antibodies and the emergence of biosimilar versions of originator mAbs. For example, in 2016, a

In 2018, 13 mAbs (a record ten antibodies (seven11 originator mAbs and three biosimilar antibodies)two biosimilars) were approved by the FDAU.S. Food and Drug Administration (“FDA”) to treat a diverse range of diseases.

Between 2016 and 2018, 36 mAbs were approved by the FDA, representing over 40% of all approved mAbs since the first therapeutic antibody was brought to market in 1986. There are currently more than 30080 mAbs on the market and more than 400 in various stages of clinical development addressing a wide range of medical conditions including asthma, migraines and Alzheimer’s disease.

In addition to investments in the discovery and development of novel biologic drugs, there has been substantial investment infollow-on products (biosimilars) by generic and specialty pharmaceutical as well as large biopharmaceutical companies. We believe developmentDevelopment offollow-on products is acceleratinghas accelerated as the first major mAbs begin tohave come off patent in the European Union and United States. For example, there are at least 12 companies attempting to market the first Humira® (adalimumab) biosimilar, for which patent protection expired in the United States at the end of 2016. Also, dueDue to the high cost of biologic drugs, many countries in the developing and emerging markets have been aggressively investing in biomanufacturing capabilities to supply

lower cost alternatives or biosimilars for the local markets. We believe theyFor both originator andfollow-on biologics manufacturing, Repligen products are focused on innovative technologies that offerwell-positioned to enable greater manufacturing flexibility, production yields and lower-costslower costs through improved process efficiencies.

Many of the products we manufacture are in the early stages of their adoption cycle, and together with the expansion of our commercial organization and strategic acquisitions, have contributed to product revenue growth from $47.5 million in 2013, to $193.9 million in 2018. While all product lines have grown over this period, our diversification strategy has resulted in a significant increase in direct product sales as a percent of total product revenue, from 17% in 2012. By 2018, 72% of total bioprocessing revenue was attributable to direct product sales; 47% from our Filtration product line, 23% from our Chromatography product line and a small percentage from other sources including sales of hospital products that we obtained through our acquisition of Spectrum.

Customers use our products to produce initial quantities of drug for clinical studies, and thenscale-up to larger volumes as the drug progresses to commercial production following regulatory approval. Detailed specifications for a drug’s manufacturing process are included in applications that must be approved by regulators, such as the FDA, and the European Medicines Agency (“EMA”), throughout the clinical trial process and prior to final commercial approval. As a result, products that become part of the manufacturing specifications of a late-stage clinical or commercial process can be very sensitive given the costs and uncertainties associated with displacing them.

The Biologics Manufacturing Process

Manufacturing biologic drugs requires three fundamental steps. First, upstream manufacturing involves the production of the biologic by living cells that are grown in a bioreactor under controlled conditions. Methods of production vary with the industry standard beingfed-batch, where nutrients (media) are added to a bioreactor to

stimulate cell growth and productivity and then followed by a harvest step. The industry is increasingly adopting the perfusion (or continuous) method of production, which circulates nutrients into the bioreactor, while simultaneously harvesting the biologic drug product. Some manufacturers are embracing a hybrid approach combining bothfed-batch and perfusion methods. The cells being grown in a bioreactor are engineered to produce the biologic drugs of interest. These cells, or factories,tiny cell “factories” are highly sensitive to the conditions under which they grow, including the composition of the cell culture media and the growth factors used to stimulate increased cell growth and protein production, or titre. In the second downstream step, the biologic made upstream must be separated and purified, typically through various filtration and chromatography steps. In the third stage of the process,Finally, the purified biologic drug is concentrated and formulated and then quality controlled and packaged into its final injectable form.

Biologics are generally high value therapies. Given the inherent complexities of the process and the final drug product, we have observed that manufacturers are seeking and investing in innovative technologies that address pressure points in the production process in order to improve yields. We see that manufacturersManufacturers are also seeking technologies that reduce costs as the biologic drug moves through clinical stages and into commercial processes by adoptingsingle-use technologies as well as other products that confer moreyield increased flexibility and efficiency.

Our Strategy

We are focused on the development, production and commercialization of differentiated, technology-leading solutions or products that address specific pressure points in the biologics manufacturing process and deliver substantial value to our customers. WeOur products are designed to increase our customers’ product yield, and we are committed to supporting our customers with strong customer service and applications expertise.

We intend to build on our recent history of developing market leadingmarket-leading solutions and delivering strong financial performance through the following strategies.strategies:

Protein Products

Protein A

We are the leading provider of Protein A ligands, an essential component of Protein A chromatography resins (media) used in the purification of virtually all mAb-based drugs on the market (more than 50) or in development (more than 300). We manufacture multiple forms of Protein A ligands under long term supply agreements for major life sciences companies including GE Healthcare and MilliporeSigma, who in turn sell their Protein A chromatography media to end users (biopharmaceutical manufacturers). We have two manufacturing sites, one in Lund, Sweden and another in Waltham, MA, collectively supporting overall global demand for our Protein A ligands. On February 22, 2016, we amended our long term supply agreements with GE Healthcare to, among other things, extend the terms of the supply agreement relating to our Lund, Sweden facility through 2019. The supply agreement relating to our Waltham, MA facility runs through 2021. We also extended a long term supply agreement with MilliporeSigma for Protein A ligands through 2023. This dual manufacturing capability gives us strong business continuity and reduces overall supply risk for our major customers.

Protein A chromatography media is considered the industry standard for purification of antibody-based therapeutics (primarily mAbs, and also including bi-specific antibodies and antibody drug conjugates), due to the ability of Protein A to selectively bind to or “capture” antibodies from crude protein mixtures. Protein A media is packed into chromatography columns as the standard first step in a purification process. As a result of Protein A’s high affinity for antibodies, the product is highly purified and concentrated within this first capture step before moving to polishing steps. The global Protein A media market that we supply generates annual revenues of $350-$400 million. We expect continued growth for our Protein A ligands as new drugs are approved and biosimilar manufacturing accelerates.

Cell Culture Growth Factors

Most biopharmaceuticals are produced through a mammalian cell fermentation process. In order to stimulate increased cell growth and maximize overall yield from a bioreactor, manufacturers often add growth factors, such as insulin, to the cell culture fermentation media. As part of the Novozymes Acquisition, we acquired several cell culture growth factor additives. Among those products is LONG®R3 IGF-1, our insulin-like growth factor that has been shown to be 100 times more biologically potent than insulin (the industry standard), thereby increasing recombinant protein production in cell culture fermentation applications. LONG®R3 IGF-1 is currently used in the manufacture of several commercial biopharmaceutical products and is sold through a distribution partnership with MilliporeSigma. Our goal over the last few years with MilliporeSigma has been to focus on pipeline development and work with customers already familiar with the product to more broadly adopt LONG®R3 IGF-1 as a platform product.

We estimate that the current market for cell culture growth factors is $75-$80 million. We are gaining share of this market as customers displace insulin with LONG®R3 IGF-1.

Chromatography Products

Our chromatography portfolio includes a number of products used in the downstream purification and quality control of biological drugs. The main driver of growth in this portfolio is our OPUS pre-packed chromatography (PPC) column line. Our other products include Protein A chromatography resins used in a small number of commercial drug processes and ELISA test kits used by quality control departments to detect and measure the presence of leached Protein A and/or growth factor in the final product. In April 2016, we acquired the OPUS PD (formerly MediaScout) PPC manufacturing business through our acquisition of Atoll GmbH, expanding our chromatography portfolio into high throughput process development screening, viral validation studies and scale down validation of chromatography processes.

Chromatography columns, packed with chromatography media, are used in biomanufacturing to purify the biological drugs once separated, typically using filtration technology, from the contents of a bioreactor. For late-stage clinical and large commercial processes, stainless steel columns are standard, and are packed in-house by the biomanufacturer. For clinical stage manufacturing, biomanufacturers value the quick turnover, cost savings and convenience of using pre-packed columns such as OPUS versus traditional glass columns.

OPUS columns are pre-packed with purification media and are an efficient plug-and-play solution for our customers, and represent a growing area of our business. As biomanufacturers have become acutely focused on improving the drug development process, they are moving towards flexible manufacturing and disposable solutions such as OPUS. In recent years, we have observed customers moving away from in-house solutions (self-packed glass columns). They are starting to adopt the OPUS ready-to-use format due to convenience, flexibility and consistent product performance. OPUS columns save labor time, reduce overall costs and improve overall manufacturing efficiency, allowing biomanufacturers to reassign resources to higher value-add processes.

Our OPUS line is distinctly open platform, providing desirable opportunities for customization. For example, most biopharmaceutical manufacturers utilize three different chromatography media in a given process, and our flexible columns are designed to meet these needs. We differentiate ourselves in the pre-packed column space by packing any brand of chromatography media in OPUS to any bed height, ensuring the most convenient and efficient process for end users. The plug-and-play nature of our OPUS columns make them ideal for purification of antibodies and recombinant proteins. With the launch of OPUS 45cm diameter columns in 2014 and 60cm columns in 2015, we have further differentiated ourselves from our competitors who offer a limited number of column diameter and resin (media) options. By offering these larger columns, we are making inroads in the glass column market which customers typically self-pack. To address customer feedback and further enhance our product offering, we developed and launched in October 2016, OPUS R, which are OPUS pre-packed columns with an innovative side port for recovering chromatography resin from inside the column. This allows our customers to re-use the unpacked resin in other applications. The unpacking port feature will be available in the first quarter of 2017 on our largest production-scale OPUS columns; we refer to these as our OPUS 45R and OPUS 60R columns.

Pre-packed chromatography columns are at the early stages of adoption; we estimate that currently, we and our competitors collectively capture approximately 30% of a $165 million addressable market. As our sales force expands and we increase the number of call points, we are seeing more multi-site adoption of our OPUS pre-packed columns, including increased use by contract manufacturers and large pharma companies, where quick turnover of multiple production runs is critical to profitability.

Filtration Products

Sius Filtration Products

We acquired the Sius line of tangential flow filtration (TFF) cassettes and hardware as part of our acquisition of TangenX Technology in December 2016. The acquisition of this product line complements our OPUS line of pre-packed chromatography columns used in downstream purification of biologics, and extends our filtration portfolio beyond our upstream XCell ATF offering.

TFF is a rapid and efficient method for separation and purification of biomolecules that is widely used in laboratory, process development and process scale applications in biopharmaceutical manufacturing. Sius is an innovative single-use TFF line of cassettes and hardware for lab-scale through process-scale biopharmaceutical manufacturing. Single-use Sius TFF cassettes with enclosed flat sheet membranes are designed to provide a high performing membrane at significantly lower cost compared to reusable TFF products. Each disposable cassette is delivered pre-sanitized, integrity tested and ready to be equilibrated and used for tangential flow diafiltration and ultrafiltration processing. Internal studies demonstrate that utilizing Sius TFF in downstream processing provides

equivalent or higher performance while reducing filter costs, labor and buffer usage, eliminating non-value added steps of cleaning and flushing required in alternative TFF products. Sius TFF cassettes are interchangeable with filter hardware from multiple manufacturers, simplifying customer trial and adoption of Sius products.

The market for TFF cassettes in downstream purification is estimated at $200 million. The Sius TFF products have started to move into this market over the last few years as more customers opt for the convenience of single-use solutions. We expect this business to grow rapidly over the next few years as the technology gets adopted and we drive a greater number of evaluations through our larger commercial organization.

XCell™ ATF

The XCell™ ATF System is a technologically advanced filtration device used in upstream processes to continuously remove cellular metabolic waste products during the course of a fermentation run, freeing healthy cells to continue producing the biologic drug of interest. XCell™ ATF was designed to both increase the density of cells in a bioreactor and extend the production run. By continuously removing waste products from the fermentor, the XCell ATF System routinely increases cell densities to 2- or 3-times the levels achieved by standard batch fermentation. As a result, product yield is increased, which improves facility utilization and can reduce the size of a bioreactor required to manufacture a given volume of biologic drug product. This is important to biomanufacturers who seek to maximize output from their existing facilities.

XCell ATF Systems consist of either a stainless steel or plastic housing that contains a hollow-fiber filter, plus an associated pump and controller. We sell the XCell ATF System in a variety of sizes (ATF 2, ATF 4, ATF 6, ATF 10) suitable for use in laboratory and scale-up all the way to production bioreactors as large as 2,000 liters. XCell ATF Systems are used in the production of several FDA-approved mAbs.

Following our acquisition of the XCell ATF System from Refine Technology in 2014, we integrated the production of XCell ATF into our operations in Waltham, MA. We also invested in and developed the single-use version of XCell ATF, which we launched in October 2016. The XCell™ ATF device is now available as the original stainless steel configuration (steel housing and replaceable filters) in all sizes, or as a single-use device (disposable housing/filter combination) in select sizes (ATF 2 su, ATF 6 su). The availability of XCell™ ATF in a single-use format eliminates the pre-use workflow associated with autoclaving, leading to an 80% reduction in implementation time. We expect these advancements will enable our customers to accelerate evaluations, eliminate autoclaving, simplify implementation time and lower initial overall cost of ownership.

We estimate that the current market for cell retention devices is approximately $125-150 million. Within this market, we expect continued growth for our XCell ATF portfolio over the next several years, as biologics manufacturing accelerates globally and as large pharmaceutical customers who have evaluated the system adopt the technology as platform.

Research and Development

Our research activities are focused on developing new high-value bioprocessing products. Specifically, we plan to focus these efforts on our expanding our product portfolio and applications for our OPUS PPC columns, XCell ATF systems, SIUS TFF, KrosFlo®, TFF systems and Sius TFFother products, and developing next generation Protein A ligands. Research and development expenses totaled approximately $7.4 million, $5.7 million and $5.6 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Sales and Marketing

Our sales and marketing strategy supports our objective of establishing Repligenstrengthening our position as a leading provider of products and services, addressing upstream, downstream and quality control needs of bioprocessing customers in the biotechnologybiopharmaceutical industry.

Direct-to-Customer Team

To support our sales goals for ourdirect-to-consumer products, we have invested in our commercial organization. Since 2014, we have significantly expanded our global commercial organization, to form a103-person commercial team as of December 31, 2018. This includes 54 people in field positions (direct sales, field applications and biopharmaceutical industries. Throughfield service), and 49 people with internal positions (marketing, product management and customer service). This expansion also includes the team of 26 highly experienced field personnel that we added with our acquisition of Spectrum in 2017. With the acquisition, we have greatly expanded our direct sales team in Asia, where we also work effectively with key distributors to serve our expanding customer base.

As part of the Spectrum integration process, we transitioned to a new sales model in 2018, whereby all sales staff now represent all Repligen products across our Chromatography and brands, including Protein A,

Filtration portfolios. Our bioprocess account managers are supported in each region by bioprocess sales specialists with expertise in either Filtration or Chromatography and by technically trained field applications specialists and field service providers, who can work closely with customers on product demonstrations, implementation and support. We believe that this model helps drive further adoption at our key accounts and also open up new sales opportunities within each region.

Spinal Muscular Atrophy

In 2009, we entered into an exclusive license agreement with a non-profit organization, FSMA, now called CureSMA, for worldwide rightsour ability to patent applications related to compositions and methods for the treatment of spinal muscular atrophy (“SMA”). FSMA had funded the development of these compounds and identified a novel enzyme target (“DcpS”) that these compounds inhibit. In 2011, we were granted U.S. Patent Nos. 7,888,366 (the ‘366 patent) and 7,985,755 (the ‘755 patent),both entitled “2,4 Diaminoquinazolines for Spinal Muscular Atrophy,” with allowed composition claims that cover both the genus and the species of the chemical structures of the lead clinical candidates. The expiration date of the ‘366 patent is in 2028 with potential for patent term extension. The expiration date of the ‘755 patent is in 2027 with potential for patent term extension. U.S. Patent No. 9,067,897, which is a continuation of the ‘366 patent, was issued in 2015 and expires in 2027. Foreign equivalents of these U.S. patents have been issued and/or are pending in Australia, Canada, Europe, Hong Kong, Japan, and New Zealand.

Pursuant to the License Agreement, we licensed all ofprotect our intellectual property relatedrights, which includes protecting the trademarks we use in connection with our products and services. We rely on several registered and unregistered trademarks to SMA to Pfizer and Pfizer assumed responsibility for maintaining existing intellectual property and prosecuting new intellectual property relating to this program. On January 26, 2015, Pfizer issued to us a notice of its termination of the License Agreement for convenience, effective as of April 26, 2015. On March 17, 2016, we entered into a Termination Agreement with CureSMA through which we returned all patent rights and transferred all related data and materials back to CureSMA.

Histone Deacetylase Inhibitors

In 2007, we entered into an exclusive license agreement with The Scripps Research Institute for worldwide rights to a patent application claiming compounds and methods for treating Friedreich’s ataxia with inhibitors of histone deacetylase. We extended this original work and filed additional patent applications which claim both methods and compositions for treating Friedreich’s ataxia. On January 21, 2014, we out-licensed all ofprotect our intellectual property related to HDAC to BioMarin, and BioMarin has assumed responsibility for maintaining existing intellectual property and prosecuting new intellectual property relating to this program. Our out-licensed HDACi portfolio included patent applications in the United States as well as patent applications in Europe, Canada, Japan and Australia. Patents, if any, that are granted in the U.S. based on these patent applications are expected to expire from 2029 to 2032.brand.

Licensing Agreements

HDAC Agreement with BioMarin

On January 21, 2014, we out-licensed our HDACi portfolio, which includes the Friedreich’s ataxia program, to BioMarin Pharmaceuticals Inc. Friedreich’s ataxia is an inherited disease that causes progressive damage to the nervous system resulting in symptoms ranging from impaired walking and speech problems to heart disease. Pursuant to the terms of the agreement, BioMarin agrees to use commercially reasonable efforts to commercialize HDACi portfolio product until the later of (i) the expiration of the last-to-expire valid claim of an issued and unexpired patent or pending patent application claiming a compound included in the agreement or (ii) 10 years. Under the terms of the agreement, Repligen received an upfront payment of $2 million in January 2014 from BioMarin and we have the potential to receive up to $160 million in future milestone payments for BioMarin’s development, regulatory approval and commercial sale of portfolio compounds included in the agreement. These potential milestone payments are approximately 37% related to clinical development and 63% related to initial commercial sales in specific geographies. In addition, Repligen is eligible to receive royalties on sales of qualified products developed. The royalty rates are tiered and begin in the mid-single-digits for the first

HDACi portfolio product and for the first non-HDACi portfolio product with lesser amounts for any backup products developed under the agreement. Repligen’s receipt of these royalties is subject to customary offsets and deductions. There are no refund provisions in this agreement. Royalties under this agreement are paid on a country-by-country basis during the period beginning on the first commercial sale of a compound in such country, until the later of: (i) the expiration of exclusivity period granted by a governmental authority to prevent the entry of generic product into such country; (ii) the expiration of the last-to-expire valid claim of an issued and unexpired patent or pending patent application claiming such compound in such country; or (iii) ten years following the first commercial sale of such HDACi portfolio product in any country. Royalty payments on products derived from the compounds included in the agreement are calculated by multiplying net sales of such product for the calendar year by an applicable royalty rate based on incremental net sale amounts. We have no further obligationsentered into multiple licensing and collaboration relationships with third-party business partners in an effort to BioMarin.

Competition

Our bioprocessing products compete on the basis of quality, performance, cost effectiveness, and application suitability with numerous established technologies. Additional products using new technologies that may be competitive with our products may also be introduced. Many of the companies selling or developing competitive products, which in some cases includesinclude GE Healthcare and MilliporeSigma, our two largest customers, have greater financial and human resources, research and development, manufacturing and marketing experience than we do. They may undertake their own development of products that are substantially similar to or compete with

our products and they may succeed in developing products that are more effective or less costly than any that we may develop. These competitors may also prove to be more successful in their production, marketing and commercialization activities. We cannot be certain that the research, development and commercialization efforts of our competitors will not render any of our existing or potential products obsolete.

RISK FACTORS

Investors should carefully consider the risk factors described below before making an investment decision.

If any of the events described in the following risk factors occur, our business, financial condition or results of operations could be materially harmed. In that case the trading price of our common stock could decline, and investors may lose all or part of their investment. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial may also become important factors that affect Repligen.

The bioprocessing market is intensely competitive, subject to rapid change and significantly affected by new product introductions and other market activities of industry participants.

Many of our competitors are large, well-capitalized companies with significantly more market share and resources than we have. As a consequence, they are able to spend more aggressively on product development, marketing, sales and other product initiatives than we can. Many of these competitors have:

 

significantly greater name recognition;

 

larger and more established distribution networks;

 

additional lines of products and the ability to bundle products to offer higher discounts or other incentives to gain a competitive advantage;

 

greater experience in conducting research and development, manufacturing, clinical trials, marketing, obtaining regulatory approval and entering into collaboration or other strategic partnership arrangements; and

greater financial and human resources for product development, sales and marketing and patent litigation.

Our current and future competitors, or other companiesincluding certain of our customers, may at any time develop additional products that compete with our products. If an existing or future competitorany company develops products that compete with or are superior to our products, our revenue may decline. In addition, some of our competitors may compete by lowering the price of their products. If prices were to fall, we may not be able to improve our gross margins or sales growth sufficiently to maintain and grow our profitability.

We dependDespite our increasingly diversified client base, we have historically depended on, and expect to continue to depend on, a limited number of customers for a high percentage of our revenues.

The loss of, or a significant reduction in orders from, any of theseour large customers, including following any termination or failure to renew a long-term supply contract, would significantly reduce our revenues and harm our results of operations. If a large customer purchases fewer of our products, defers orders or fails to place additional orders with us for any other reason, including for business continuity purposes, our revenue could decline, and our operating results may not meet market expectations. Under our long-term supply agreements with GE Healthcare (“GE”), we supply Protein A ligands to GE from our manufacturing facilities in Lund, Sweden and Waltham, Massachusetts (the “Lund Agreement” and “Waltham Agreement,” respectively). The Lund Agreement runs pursuant to its terms, through 2019 and the Waltham Agreement runs, pursuant to its terms, through 2021. GE may elect, upon six months’ prior notice to us, to reduce its minimum purchase requirements under the Lund Agreement. Even if GE so elects, GE would still be required to continue to purchase at least 50% of its global demand pursuant to the Waltham Agreement through the expiration of this agreement pursuant to its terms on December 31, 2021.

In addition, if thoseour customers order our products, but fail to pay on time or at all, our liquidity and operating results could be materially and adversely affected. Furthermore, if any of our current or future products compete with those of any of our largest customers, these customers may place fewer orders with us or cease placing orders with us, which would negatively affect our revenues and operating results.

If we are unable to expand our product portfolio, our ability to generate revenue could be adversely affected.

In connection with the Company’s decision to focus our efforts on the growth of our core bioprocessing business, weWe are increasingly seeking to develop and commercialize our own portfolio of products. Our future financial performance will depend, in part, on our ability to successfully develop and acquire additional bioprocessing products. There is no guarantee that we will be able to successfully acquire or develop additional bioprocessing products, and the Company’s financial performance will likely suffer if we are unable to do so.

If intangible assets and goodwill that we recorded in connection with our acquisitions become impaired, we couldmay have to take significant charges against earnings.

In connection with the accounting for the Novozymes Acquisition, the Refine Acquisition, the Atoll Acquisition and the TangenX Acquisition,our completed acquisitions, we recorded a significant amount of intangible assets, including developed technology and customer relationships relating to the acquired product lines, and goodwill. Under U.S. GAAP, we must assess, at least annually and potentially more frequently, whether the value of intangible assets and goodwill has been impaired. Intangible assets and goodwill will be assessed for impairment in the event of an impairment indicator. Any reduction or impairment of the value of intangible assets and goodwill will result in a charge against earnings, which could materially adversely affect our results of operations and shareholders’ equity in future periods.

Our exposure to political, economic and other risks that arise from operating a multinational business has and may continue to increase.

We operate on a global basis with offices or activities in Japan, South Korea, China, India, Europe and North America. Our operations and sales outside of the United States have increased as a result of the Novozymes Acquisition, the Refine Acquisition and the Atoll Acquisitionour strategic acquisitions and the continued expansion of our commercial organization. Risks related to these increased foreign operations include:

 

fluctuations in foreign currency exchange rates;rates, which may affect the costs incurred in international operations and could harm our results of operations and financial condition;

 

changes in general economic and political conditions in countries where we operate, particularly as a result of ongoing economic instability within the European Union and other foreign jurisdictions;

the occurrence of a trade war, or other governmental action related to tariffs or trade agreements;

being subject to complex and restrictive employment and labor laws and regulations, as well as union and works council restrictions;

 

changes in tax laws or rulings in the United States or other foreign jurisdictions that may have an adverse impact on our effective tax rate;

 

being subject to burdensome foreign laws and regulations, including regulations that may place an increased tax burden on our operations;

 

being subject to longer payment cycles from customers and experiencing greater difficulties in timely accounts receivable collections; and

 

required compliance with a variety of foreign laws and regulations.regulations, such as data privacy requirements, real estate and property laws, anti-competition regulations, import and trade restrictions, export requirements, U.S. laws such as the Foreign Corrupt Practices Act of 1977 and the U.S. Department of Commerce’s Export Administration Regulations, and other U.S. federal laws and regulations established by the office of Foreign Asset Control, local laws such as the U.K. Bribery Act of 2010 or other local laws that prohibit corrupt payments to governmental officials or certain payments or remunerations to customers.

Our business success depends in part on our ability to anticipate and effectively manage these and other.other related factors. We cannot assure you that these and other related factors will not materially adversely affect our international operations or business as a whole.

In addition, a deterioration in diplomatic relations between the United States and any country where we conduct business could adversely affect our future operations and lead to a decline in profitability.

We may be unable to efficiently manage efficiently having becomeour growth as a larger and more geographically diverse organization.

Our strategic acquisitions, of Novozymes, Refine, Atoll and TangenX, the continued expansion of our commercial sales operations, and our organic growth have increased the scope and complexity of our business. WeAs a result, we will face challenges inherent in efficiently managing a more complex business with an increased number of employees over large geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs. Our inability to manage successfully the geographically more diverse (including from a cultural perspective) and substantially larger combined organization could materially adversely affect our operating results and, as a result, the market price of our common stock.

Our business is subject to a number of environmental risks.

Our manufacturing business involves the controlled use of hazardous materials and chemicals and is therefore subject to numerous environmental and safety laws and regulations and to periodic inspections for possible violations of these laws and regulations. In addition to these hazardous materials and chemicals, our facility in Sweden also uses Staphylococcus aureus and toxins produced by Staphylococcus aureus in some of its manufacturing processes. Staphylococcus aureus and the toxins it produces, particularly enterotoxins, can cause severe illness in humans. The costs of compliance with environmental and safety laws and regulations are significant. Any violations, even if inadvertent or accidental, of current or future environmental and safety laws or regulations and the cost of compliance with any resulting order or fine could adversely affect our operations.

Our acquisitions expose us to risks that could adversely affect our business, and we may not achieve the anticipated benefits of acquisitions of businesses or technologies.

In addition to our acquisitions of Novozymes, Refine, Atoll and TangenX, and asAs a part of our growth strategy, we may make selected acquisitions of complementary products and/or businesses. Any acquisition involves numerous risks and operational, financial, and managerial challenges, including the following, any of which could adversely affect our business, financial condition, or results of operations:

 

difficulties in integrating new operations, technologies, products, and personnel;

 

problems maintaining uniform procedures, controls and policies with respect to our financial accounting systems;

 

lack of synergies or the inability to realize expected synergies and cost-savings;

 

difficulties in managing geographically dispersed operations;operations, including risks associated with entering foreign markets in which we have no or limited prior experience;

underperformance of any acquired technology, product, or business relative to our expectations and the price we paid;

 

negative near-term impacts on financial results after an acquisition, including acquisition-related earnings charges;

 

the potential loss of key employees, customers, and strategic partners of acquired companies;

 

claims by terminated employees and shareholders of acquired companies or other third parties related to the transaction;

 

the assumption or incurrence of additional debt obligations or expenses, or use of substantial portions of our cash;

the issuance of equity securities to finance or as consideration for any acquisitions wouldthat dilute the ownership of our stockholders;

 

the issuance of equity securities to finance or as consideration for any acquisitions may not be an option of if the price of our common stock is low or volatile which could preclude us from completing any such acquisitions;

 

any collaboration, strategic alliance and licensing arrangement may require us to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us;

 

diversion of management’s attention and company resources from existing operations of the business;

 

inconsistencies in standards, controls, procedures, and policies;

 

the impairment of intangible assets as a result of technological advancements, or worse-than-expected performance of acquired companies; and

 

assumption of, or exposure to, historical liabilities of the acquired business, including unknown contingent or similar liabilities that are difficult to identify or accurately quantify.quantify; and

risks associated with acquiring intellectual property, including potential disputes regarding acquired companies’ intellectual property.

In addition, the successful integration of acquired businesses requires significant efforts and expense across all operational areas, including sales and marketing, research and development, manufacturing, finance, legal, and information technologies. There can be no assurance that any of the acquisitions we may make will be successful or will be, or will remain, profitable. Our failure to successfully address the foregoing risks may prevent us from achieving the anticipated benefits from any acquisition in a reasonable time frame, or at all.

Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to make payments on our debt.

We incurred significant indebtedness in the amount of $115.0 million in aggregate principal with additional accrued interest under our 2.125% Convertible Senior Notes due 2021 (the “Notes”). Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, including the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors that may be beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. In addition, in the event of a fundamental change or a default under the Notes, the holders and/or the trustee under the indentures governing the Notes may accelerate the payment obligations or trigger the holders’ repurchase rights under the Notes. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, including the Notes.

If a make-whole fundamental change, such as an acquisition of our company, occurs prior to the maturity of the Notes, under certain circumstances, the conversion rate for the Notes will increase such that additional shares of our common stock will be issued upon conversion of the Notes in connection with such make-whole fundamental change. The increase in the conversion rate will be determined based on the date on which the make-whole fundamental change occurs or becomes effective and the price paid (or deemed paid) per share of our common stock in such transaction. Upon conversion of the Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Notes being converted. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of Notes surrendered therefor or

notes being converted. Our failure to repurchase Notes at a time when the repurchase is required by the indenture or to pay any cash payable on future conversions of the Notes as required by the indenture would constitute a default under the indenture. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes or make cash payments upon conversions thereof.

In addition, our significant indebtedness, combined with our other financial obligations and contractual commitments, could have other important consequences. For example, it could:

 

make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry and competitive conditions and adverse changes in government regulation;

 

limit our flexibility in planning for, or reacting to, changes in our business and our industry;

 

place us at a disadvantage compared to our competitors who have less debt; and

 

limit our ability to borrow additional amounts for working capital and other general corporate purposes, including to fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies.

Any of these factors could materially and adversely affect our business, financial condition and results of operations. In addition, if we incur additional indebtedness, the risks related to our business and our ability to service or repay our indebtedness would increase.

Future strategic transactions or acquisitions may require us to seek additional financing, which we may not be able to secure on favorable terms, if at all.

We plan to continue a strategy of growth and development for our bioprocessing business, and we actively evaluate various strategic transactions on an ongoing basis, including licensing or acquiring complementary products, technologies or businesses that would complement our existing portfolio of development programs. In order to complete such strategic transactions, we may need to seek additional financing to fund these investments and acquisitions. Should we need to do so, we may not be able to secure such financing, or obtain such financing on favorable terms because of the volatile nature of the biotechnology marketplace. In addition, future acquisitions may require the issuance or sale of additional equity or debt securities, which may result in additional dilution to our stockholders.

We rely on a limited number of suppliers or, for certain of our products, one supplier, and we may not be able to find replacements or immediately transition to alternative suppliers, which could have a material adverse effect on our financial condition, results of operations and reputation.

There are only a limited number of suppliers of materials related to the XCell ATF Systemfor certain of our products. An interruption in operations of the business related to these products could occur if we encounter delays or difficulties in securing thesethe required materials, or if we cannot then obtain an acceptable substitute. Any such interruption could significantly affect the business related to these products and our financial condition, results of operations and reputation.

For example, we believe that only a small number of suppliers are currently qualified to supply materials for the XCell ATF System. The use of materials furnished by these replacement suppliers would require us to alter our operations related to the XCell ATF System. Transitioning to a new supplier for our products would be time consuming and expensive, may result in interruptions in our operations, could affect the performance specifications of our product lines or could require that we revalidate the materials. There can be no assurance that we will be able to secure alternative materials and bring such materials on line and revalidate them without experiencing interruptions in our workflow. If we should encounter delays or difficulties in securing, reconfiguring or revalidating the materials required for our products, our business related to these products and our financial condition, results of operations and reputation could be adversely affected.

We have limited sales and as

As we evolve from a company dependent on others to commercialize our products to a company selling directly to end users, we may encounter difficulties in expanding our product portfolio and our commercial marketing capabilities.

We have a small sales force and, priorPrior to 2016, we generated most of our revenues through sales of bioprocessing products to a limited number of life sciences companies, such as GE Healthcare, MilliporeSigma and through other individual distributors. However, due in part to our recent strategic acquisitions, an increasing amount of our revenue is attributable to our commercialization of bioprocessing products that we sell directly toend-users, such as including biopharmaceutical companies and contract manufacturing organizations. This has required and will continue to require us to invest additional resources in our sales and marketing capabilities. We may not be able to attract and retain additional sales and marketing professionals, and the cost of building the sales and marketing function may not generate our anticipated revenue growth. In addition, our sales and marketing efforts may be unsuccessful. Our failure to manage these risks may have a negative impact on our financial condition, or results of operations and may cause our stock price to decline.

If we are unable to obtain or maintain our intellectual property, we may not be able to succeed commercially.

We endeavor to obtain and maintain trade secrets and, to a lesser extent with respect to the products that currently account for a majority of our revenue, patent and trade secret protection for our products and processes when available in order to protect themour products and processes from unauthorized use and to produce a financial return consistent with the significant time and expense required to bring our products to market. Our success will depend, in part, on our ability to:

 

preserve our trade secrets andknow-how;

operate without infringing the proprietary rights of third parties;

obtain and maintain patent protection for our products and manufacturing processes; and

 

preserve our trade secrets;

operate without infringing the proprietary rights of third parties; and

secure any necessary licenses from others on acceptable terms.

We consider trade secrets,know-how and other forms of market protection to be among the most important elements of our proprietary position, in particular, as it relates to the products that currently account for a majority of our revenue. We also own or have exclusive rights to a number of U.S. patents and U.S. pending patent applications as well as corresponding foreign patents and patent applications. We continue to actively and selectively pursue patent protection and seek to expand our patent estate, particularly for our products currently in development, and we cannot be sure that any patent applications relating to our products that we will file in the future or that any currently pending applications will issue on a timely basis, if ever. Since patent applications in the United States filed prior to November 2000 are maintained in secrecy until patents issue and since publication of discoveries in the scientific or patent literature often lag behind actual discoveries, weWe cannot be certain that we were the first to make the inventions covered by each of our pending patent applications or that we were the first to file patent applications for such inventions. Even if patents are issued, the degree of protection afforded by such patents will depend upon the:

 

scope of the patent claims;

 

validity and enforceability of the claims obtained in such patents; and

 

our willingness and financial ability to enforce and/or defend them.

The patent position of life sciences companies is often highly uncertain and usually involves complex legal and scientific questions. Patents which may be granted to us in certain foreign countries may be subject to opposition proceedings brought by third parties or result in suits by us, which may be costly and result in adverse consequences for us.

In some cases, litigation or other proceedings may be necessary to assert claims of infringement, to enforce patents issued to us or our licensors, to protect trade secrets,know-how or other intellectual property rights we own or to determine the scope and validity of the proprietary rights of third parties. Such litigation could result in

substantial cost to us and diversion of our resources. An adverse outcome in any such litigation or proceeding could have a material adverse effect on our business, financial condition and results of operations.

If our competitors prepare and file patent applications in the United States that claim technology also claimed by us, we may be required to participate in interference proceedings declared by the U.S. Patent and Trademark Office to determine priority of invention, which would result in substantial costs to us.

While one of our U.S. patents covering recombinant Protein A had its term adjusted to expire in 2028, our other U.S. patents covering recombinant Protein A have expired, and as a result, we may face increased competition, which could harm our results of operations, financial condition, cash flow and future prospects.

Other companies could begin manufacturing and selling native or some of the commercial forms of recombinant Protein A in the U.S.United States and may directly compete with us on certain Protein A products. This may induce us to sell Protein A at lower prices and may erode our market share, which could adversely affect our results of operations, financial condition, cash flow and future prospects.

Our freedom to develop our products may be challenged by others, and we may have to engage in litigation to determine the scope and validity of competitors’ patents and proprietary rights, which, if we do not prevail, could harm our business, results of operations, financial condition, cash flow and future prospects.

There has been substantial litigation and other proceedings regarding the complex patent and other intellectual property rights in the life sciences industry. We have been a party to, and in the future may become a party to, patent litigation or other proceedings regarding intellectual property rights.

Other types of situations in which we may become involved in patent litigation or other intellectual property proceedings include:

 

We may initiate litigation or other proceedings against third parties to seek to invalidate the patents held by such third parties or to obtain a judgment that our products or services do not infringe such third parties’ patents.

 

We may initiate litigation or other proceedings against third parties to seek to enforce our patents against infringement.

 

If our competitors file patent applications that claim technology also claimed by us, we may participate in interference or opposition proceedings to determine the priority of invention.

 

If third partiesthird-parties initiate litigation claiming that our processes or products infringe their patent or other intellectual property rights, we will need to defend against such claims.

The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the cost of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. If a patent litigation or other intellectual property proceeding is resolved in a way that is unfavorable to us, we or our collaborative or strategic partners

may be enjoined from manufacturing or selling our products and services without a license from the other party and be held liable for significant damages. The failure to obtain any required license on commercially acceptable terms or at all may harm our business, results of operations, financial condition, cash flow and future prospects.

Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time, attention and resources.

We may become involved in litigation or other proceedings with collaborative partners, which may be time consuming, costly and could result in delays in our development and commercialization efforts.

In connection with the Company’s decision to focus its efforts on the growth of its core bioprocessing business, we sought development and commercialization partnerships for our remaining portfolio of clinical stage assets. Any disputes with such partners such as BioMarin, that lead to litigation or similar proceedings may result in us incurring legal expenses, as well as facing potential legal liability. Such disputes, litigation or other proceedings are also time consuming and may cause delays in our development and commercialization efforts. If we fail to resolve these disputes quickly and with terms that are no less favorable to us than the current terms of the arrangements, our business, results of operations, financial condition, cash flow and future prospects may be harmed.

If we are unable to continue to hire and retain skilled personnel, then we will have trouble developing and marketing our products.

Our success depends largely upon the continued service of our management and scientific staff and our ability to attract, retain and motivate highly skilled technical, scientific, management and marketing personnel. We also face significant competition in the hiring and retention of such personnel from other companies, research and academic institutions, government and other organizations who have superior funding and resources. The loss of key personnel or our inability to hire and retain skilled personnel could materially adversely affect our product development efforts and our business.

The market may not be receptive to our new bioprocessing products upon their introduction.

We expect a portion of our future revenue growth to come from introducing new bioprocessing products, including line extensions and new features for our OPUS disposable chromatography columns, our XCell ATF System, our SiusSIUS TFF product line, our Spectrum hollow fiber modules and TFF systems and our growth factors. For example, in 2016, we introduced a resin recovery port on our largest OPUS columns, and we launched single-use versions of XCell ATF Systems. The commercial success of all of our products will depend upon their acceptance by the life science and biopharmaceutical industries. Many of the bioprocessing products that we are developing are based upon new technologies or approaches. As a result, there can be no assurance that these new products, even if successfully developed and introduced, will be accepted by customers. If customers do not adopt our new products and technologies, our results of operations may suffer and, as a result, the market price of our common stock may decline.

If our newOur products do not achieve sufficient market acceptance, our resultsare subject to quality control requirements.

Whether a product is produced by us or purchased from outside suppliers, it is subjected to quality control procedures, including the verification of operationsporosity and competitive position could suffer.

There can be no assurance that unforeseen problems will not occur with respectcertain products, the complete validation for good manufacturing practices, U.S. Food and Drug Administration, CE and ISO 2001 compliance, prior to final packaging. Quality control is performed by a staff of technicians utilizing calibrated equipment. In the development, performance or market acceptance of new products or thatevent we, will otherwise be able to successfully develop and market new products. Failure of our new products to gain market acceptance or our failuremanufacturers, produce products that fail to successfully developcomply with required quality standards, it may incur delays in fulfilling orders, write-downs, damage to our reputation and market new products could reduce our margins, which would have an adverse effect on our business, financial condition and results of operations.damages resulting from product liability claims.

If our products do not perform as expected or the reliability of the technology on which our products are based is questioned, we could experience lost revenue, delayed or reduced market acceptance of our products, increased costs and damage to our reputation.

Our success depends on the market’s confidence that we can provide reliable, high-quality bioprocessing products. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors. Our reputation and the public image of our products and technologies may be impaired if our products fail to perform as expected. Although our products are tested prior to shipment, defects or errors could nonetheless occur in our products. Furthermore, the Protein A that we manufacture is subsequently incorporated into products that are sold by other life sciences companies and we have no control over the manufacture and

production of those products. In the future, if our products experience, or are perceived to experience, a material defect or error, this could result in loss or delay of revenues, delayed market acceptance, damaged reputation, diversion of development resources, legal claims, increased insurance costs or increased service and warranty costs, any of which could harm our business. Such defects or errors could also narrow the scope of the use of our products, which could hinder our success in the market. Even after any underlying concerns or problems are resolved, any lingering concerns in our target market regarding our technology or any manufacturing defects or performance errors in our products could continue to result in lost revenue, delayed market acceptance, damaged reputation, increased service and warranty costs and claims against us.

If we are unable to manufacture our products in sufficient quantities and in a timely manner, our operating results will be harmed, our ability to generate revenue could be diminished and our gross margin may be negatively impacted.

Our revenues and other operating results will depend in large part on our ability to manufacture and assemble our products in sufficient quantities and in a timely manner. Any interruptions we experience in the manufacturing or shipping of our products could delay our ability to recognize revenues in a particular quarter. Manufacturing problems can and do arise, and as demand for our products increases, any such problems could have an increasingly significant impact on our operating results. While we have not generally experienced problems with, or delays in, our production capabilities that resulted in delays in our ability to ship finished products, there can be no assurance that we will not encounter such problems in the future. We may not be able to quickly ship products and recognize anticipated revenues for a given period if we experience significant delays in the manufacturing process. In addition, we must maintain sufficient production capacity in order to meet anticipated customer demand, which carries fixed costs that we may not be able to offset if orders slow, which would adversely affect our operating margins. If we are unable to manufacture our products consistently, in sufficient quantities, and on a timely basis, our bioprocessing revenue, gross margins and our other operating results will be materially and adversely affected.

Our operating results may fluctuate significantly, our customers’ future purchases are difficult to predict and any failure to meet financial expectations may result in a decline in our stock price.

Our quarterly operating results may fluctuate in the future as a result of many factors such as the impact of seasonal spending patterns, changes in overall spending levels in the life sciences industry, the inability of some of our customers to consummate anticipated purchases of our products due to changes inend-user demand, and other unpredictable factors that may affect ordering patterns. Because our revenue and operating results are difficult to predict, we believe thatperiod-to-period comparisons of our results of operations are not a good indicator of our future performance. Additionally, if revenue declines in a quarter, whether due to a delay in recognizing expected revenue, adverse economic conditions or otherwise, our results of operations will be harmed because many of our expenses are relatively fixed. In particular, a large portion of our manufacturing costs, our research and development, sales and marketing and general and administrative expenses are not significantly affected by variations in revenue. Further, our gross margins are dependent on product mix. A shift in sales mix away from our higher margin products to lower margin products will adversely affect our gross margins. If our quarterly operating results fail to meet investor expectations, the price of our common stock may decline.

Securities or industry analysts may not publish favorable research or reports about our business or may publish no information, which could cause our stock price or trading volume to decline.

Our future revenues pursuant toThe trading market for our asset purchase agreement with BioMarincommon stock is influenced by the research and reports that industry or securities analysts publish about us and our business. We do not have any control over these analysts and we cannot provide any assurance that analysts will cover us or provide favorable coverage. If any of the analysts who cover us issue an adverse opinion regarding the HDACi program depends significantly on BioMarin’s development and commercialization activities, over which we have no control.our stock price, our business or stock price would likely decline. If BioMarin is unableone or determines not to further develop or commercialize the HDACi program, or experiences significant delays in doing so, we may see a delay in receiving any potential milestone or royalty paymentsmore of these analysts cease coverage of our company or fail to receive any additional financial benefits from the program.

We entered into an asset purchase agreement with BioMarin on January 21, 2014, related to the histone deacetylase inhibitor (“HDACi”) portfolio, which includes the Friedreich’s ataxia program. We are dependent on BioMarin for the future success of this development program. We have no control over the conduct and timing of development efforts with respect to the HDACi program. BioMarin’s failure to devote sufficient financial and other resources to the development plan may resultregularly publish reports covering us, we could lose visibility in the delayedmarket, which in turn could cause our stock price or unsuccessful development of the program, which could leadtrading volume to the non-payment or delay in payment of milestones under the asset purchase agreement and may preclude or delay commercialization of any product under the HDACi program and any royalties we could receive on future commercial sales. Our future financial results may be harmed if BioMarin does not commercialize the HDACi program successfully or on a timely basis prior to the achievement of any milestones or the payment of any royalties to us.decline.

Health care reform measures could adversely affect our business.

The efforts of governmental and third-party payors to contain or reduce the costs of health care may adversely affect the business and financial condition of pharmaceutical and biotechnology companies, including us.ours. Specifically, in both the United States and some foreign jurisdictions, there have been a number of legislative and regulatory proposals to change the health care system in ways that could affect our ability to sell our products profitably. The U.S. Congress passed the America Affordable Health Choices Act of 2009 andFor example, in March 2010, the Patient Protection and Affordable Care Act, Thisas amended by the Health Care and Education Reconciliation Act of 2010 (together, the “Affordable Care Act”), was passed, which substantially changes the way health care is financed by both governmental and private insurers and significantly impacts the U.S. life sciences industry. The Affordable Care Act and other federal and state proposals and health care reforms could limit the prices that can be charged for the products we develop and may limit our commercial opportunity. In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, also called the Medicare Modernization Act (the “MMA”) changed the way Medicare covers and pays for pharmaceutical products. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and price that we receive for any approved products and could seriously harm our business. While the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors. Efforts by the government and other third-party payors to contain or reduce the costs of health care through various means may limit our commercial opportunities and result in a decrease in the price of our common stock or limit our ability to raise capital.

The recent presidential and congressional elections may lead to amendmentsRecent federal government efforts have been aimed at amending or repeals ofrepealing all or portions of existing health care reform legislation, including the Affordable Care Act. Changes in existing health care reform measures may result in uncertainty with respect to legislation, regulation and government policy that could significantly impact our business and the life sciences industry.

The enactment of legislation implementing changes in taxation of international business activities, the adoption of other corporate tax reform policies, or changes in tax legislation or policies could materially impact our financial position and results of operations.

Corporate tax reform, base-erosion efforts and tax transparency continue to be high priorities in many tax jurisdictions where we have business operations. As a result, policies regarding corporate income and other taxes in numerous jurisdictions are under heightened scrutiny and tax reform legislation is being proposed or enacted in a number of jurisdictions. For example, the Tax Cuts and Jobs Act (the “2017 Tax Reform Act”), adopting broad U.S. corporate income tax reform will, among other things, reduce the U.S. corporate income tax rate, but will impose base-erosion prevention measures on earnings ofnon-U.S. subsidiaries of U.S. entities as well as the transition tax on mandatory deemed repatriation of accumulatednon-U.S. earnings of U.S. controlled foreign corporations. There is no assurance that our actual income tax liability will not be materially different than what is reflected in our income tax provisions and accruals.

In addition, many countries are beginning to implement legislation and other guidance to align their international tax rules with the Organisation for EconomicCo-operation and Development’s Base Erosion and Profit Shifting recommendations and action plan that aim to standardize and modernize global corporate tax policy, including changes to cross-border tax, transfer pricing documentation rules, and nexus-based tax incentive practices. Because of the heightened scrutiny of corporate taxation policies, prior decisions by tax authorities regarding treatments and positions of corporate income taxes could be subject to enforcement activities, and legislative investigation and inquiry, which could also result in changes in tax policies or prior tax rulings. Any such changes in policies or rulings may also result in the taxes we previously paid being subject to change.

Due to the large scale of our international business activities, any substantial changes in international corporate tax policies, enforcement activities or legislative initiatives may materially adversely affect our business, the amount of taxes we are required to pay and our financial condition and results of operations generally.

We compete with life science, pharmaceutical and biotechnology companies who are capable of developing new approaches that could make our products and technology obsolete.

The market for therapeutic and commercial products is intensely competitive, rapidly evolving and subject to rapid technological change. LifeWe compete with several medium and small companies in each of our product categories as well as several large companies, including GE Healthcare, Danaher Corporation (Pall), Thermo Fisher Scientific Inc., MilliporeSigma and Sartorius. These competitors, as well as other life science, pharmaceutical and biotechnology companies may have substantially greater financial, manufacturing, marketing, and research and development resources than we have. Newhave, as well as stronger name recognition, longer operating histories and benefits derived from greater economies of scale. These factors, among others, may enable our competitors to market their products at lower prices or on terms more advantageous to customers than what we can offer. Competition may result in price reductions, reduced gross margins and loss of market share, any of which could have a material adverse effect on our business, financial condition and results of operations. Additionally, new approaches by these competitors may make our products and technologies obsolete or noncompetitive.

We may become subject to litigation, which could result in substantial costs and divert management’s attention and resources from our business.

From time to time, we may become involved in litigation or other legal proceedings relating to claims arising from the ordinary course of business. Litigation is subject to inherent risks and uncertainties that may cause actual results to differ materially from our expectations. If we receive an adverse judgment in any litigation, we could be required to pay substantial damages. With or without merit, litigation can be complex, can extend for a protracted period of time, can be very expensive and the expense can be unpredictable. Litigation initiated by us could also result in counter-claims against us, which could increase the costs associated with the litigation and result in our payment of damages or other judgments against us. In addition, litigation, and any related publicity, may divert the efforts and attention of some of our management and key personnel, which wouldcould adversely affect our business.

We may be exposed to liabilities under the Foreign Corrupt Practices Act, and any determination that we violated the Foreign Corrupt Practices Act could have a material adverse effect on our business.

We are subject to the Foreign Corrupt Practice Act (the “FCPA”) and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties by U.S. persons and issuers as defined by the statute for the purpose of obtaining or retaining business. We have operations and agreements with third parties and make sales in jurisdictions outside of the U.S.,United States, which may experience corruption. Our activities in jurisdictions outside of the U.S.United States create the risk of unauthorized payments or offers of payments by one of our employees, consultants, sales agents or distributors, because these parties are not always subject to our control. These risks have increased following our recent acquisitions of overseas operations and facilities. It is our policy to implement safeguards to discourage these practices by our employees. However, our existing safeguards and any future improvements may prove to be less than effective, and the employees, consultants, sales agents or distributors of our Company may engage in conduct for which we might be held responsible. Violations of the FCPA may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business, operating results and financial condition. In addition, the government may seek to hold us liable for successor liability FCPA violations committed by any companies in which we invest or that we acquire.

Our stock price could be volatile, which could cause shareholders to lose part or all of their investment.

The market price of our common stock, like that of the common stock of many other companies with similar market capitalizations, is highly volatile. In addition, the stock market has experienced extreme price and volume fluctuations. This volatility has significantly affected the market prices of securities of many life sciences,

biotechnology and pharmaceutical companies for reasons frequently unrelated to or disproportionate to the operating performance of the specific companies. These broad market fluctuations may adversely affect the market price of our common stock.

Anti-takeover provisions in our charter documents, certain of our contracts with third parties, and under Delaware law could make an acquisition of us, even one that may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our certificate of incorporation andby-laws may delay or prevent an acquisition of us or a change in our management. These provisions include the ability of our board of directors to issue preferred stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board were considered beneficial by some stockholders. Additionally, certain of our contracts with third parties allow for

termination upon specified change of control transactions. Anti-takeover provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management, and anti-takeover or change of control contract termination rights may frustrate or prevent any attempts by a third party to acquire or attempt to acquire the Company.

Changes in accounting standards and subjective assumptions, estimates, and judgments by management related to complex accounting matters could significantly affect our financial results or financial condition.

Generally accepted accounting principles and related accounting pronouncements, implementation guidelines, and interpretations with regard to a wide range of matters that are relevant to our business, such as revenue recognition, asset impairment and fair value determinations, inventories, business combinations and intangible asset valuations, leases, and litigation, are highly complex and involve many subjective assumptions, estimates, and judgments. Changes in these rules or their interpretation or changes in underlying assumptions, estimates, or judgments could significantly change our reported or expected financial performance or financial condition.

Our results of operations could be negatively affected by potential fluctuations in foreign currency exchange rates.

We conduct a large portion of our business in international markets. For the fiscal year ended December 31, 2016, 40%2018, 28% of our revenues and 22%15% of our costs and expenses were denominated in foreign currencies, primarily the Swedish Krona, the British pound sterling, and the Euro. We are exposed to the risk of an increase or decrease in the value of the foreign currencies relative to the U.S. Dollar, which could increase the value of our expenses and decrease the value of our revenue when measured in U.S. Dollars. As a result, our results of operation may be influenced by the effects of future exchange rate fluctuations and such effects may have an adverse impact on our common stock price.

Our ability to use net operating loss and tax credit carryforwards and certainbuilt-in losses to reduce future tax payments is limited by provisions of the Internal Revenue Code, and it is possible that certain transactions or a combination of certain transactions may result in material additional limitations on our ability to use our net operating loss and tax credit carryforwards.

Section 382 and 383 of the Internal Revenue Code of 1986, as amended, contain rules that limit the ability of a company that undergoes an ownership change, which is generally any change in ownership of more than 50% of its stock over a three-year period, to utilize its net operating loss and tax credit carryforwards and certainbuilt-in losses recognized in years after the ownership change. These rules generally operate by focusing on ownership

changes involving stockholders owning directly or indirectly 5% or more of the stock of a company and any change in ownership arising from a new issuance of stock by the company. Generally, if an ownership change occurs, the yearly taxable income limitation on the use of net operating loss and tax credit carryforwards and certainbuilt-in losses is equal to the product of the applicable long term tax exemptlong-term,tax-exempt rate and the value of the company’s stock immediately before the ownership change. We may be unable to offset our taxable income with losses, or our tax liability with credits, before such losses and credits expire and therefore would incur larger federal income tax liability. We have completed a number of financings sinceWhile our inception which may have resulted in a change in control as defined by Section 382 analysis completed during 2018 did not show any current exposure, future transactions or couldcombinations of future transactions may result in a change in control under Section 382 in the future.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report financial results or prevent fraud. If we identify a material weaknessesweakness in our internal control over financial reporting, our ability to meet our reporting obligations and the trading price of our stock could be negatively affected.

A material weakness is a deficiency,Effective internal controls are necessary to provide reliable financial reports and to assist in the effective prevention of fraud. Any inability to provide reliable financial reports or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement ofprevent fraud could harm our annual or interim financial statements will not be prevented or detected on a timely basis. Accordingly, a material weakness increases the risk that the financial information we report contains material errors.

business. We regularly review and update our internal controls, disclosure controls and procedures, and corporate governance policies. In addition, we are required under the Sarbanes-Oxley Act of 2002 to report annually on our internal control over financial reporting. Any system of internal controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. For example, in 2012, we updated our internal controls to include our operations in Sweden. If we, or our independent registered public accounting firm, determine that our internal controls over financial reporting are not effective, or we discover areas that need improvement in the future or discover a material weakness, these shortcomings could have an adverse effect on our business and financial results, and the price of our common stock could be negatively affected. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Accordingly, a material weakness increases the risk that the financial information we report contains material errors.

If we cannot conclude that we have effective internal control over our financial reporting, or if our independent registered public accounting firm is unable to provide an unqualified opinion regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements, which could lead to a decline in our stock price. Failure to comply with reporting requirements could also subject us to sanctions and/or investigations by the SEC, The NASDAQNasdaq Stock Market or other regulatory authorities.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report financial results or prevent fraud.

Effective internal controls are necessary to provide reliable financial reports and to assist in the effective prevention of fraud. Any inability to provide reliable financial reports or prevent fraud could harm our business. We must annually evaluate our internal procedures to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, which requires management and our independent registered public accounting firm to assess the effectiveness of internal control over financial reporting.

We have recentlypreviously implemented several significant ERP modules and expect to implement additional ERP modules in the future. The implementation of the ERP system represents a change in our internal control over financial reporting. Although we continue to monitor and assess our internal controls in the new ERP system environment as changes are made and new modules are implemented, and we have taken additional steps to modify and enhance the design and effectiveness of our internal control over financial reporting, there is a risk that deficiencies may occur that could constitute significant deficiencies or in the aggregate a material weakness.

If we fail to remedy any deficiencies or maintain the adequacy of our internal controls, we could be subject to regulatory scrutiny, civil or criminal penalties or shareholder litigation. In addition, failure to maintain adequate internal controls could result in financial statements that do not accurately reflect our operating results or financial condition.

Natural disasters, geopolitical unrest, war, terrorism, public health issues or other catastrophic events could disrupt the supply, delivery or demand of products, which could negatively affect our operations and performance.

We are subject to the risk of disruption by earthquakes, floods and other natural disasters, fire, power shortages, geopolitical unrest, war, terrorist attacks and other hostile acts, public health issues, epidemics or pandemics and other events beyond our control and the control of the third parties on which we depend. Any of these catastrophic events, whether in the United States or abroad, may have a strong negative impact on the global economy, our employees, facilities, partners, suppliers, distributors or customers, and could decrease demand for our products, create delays and inefficiencies in our supply chain and make it difficult or impossible for us to deliver products to our customers. A catastrophic event that results in the destruction or disruption of our data centers or our critical business or information technology systems would severely affect our ability to conduct normal business operations and, as a result, our operating results would be adversely affected.

Changes in laws and regulations governing the privacy and protection of data and personal information could adversely affect our business.

We are subject to data privacy and protection laws and regulations that apply to the collection, transmission, storage and use of proprietary information and personally-identifying information, which among other things, imposes certain requirements relating to the privacy, security and transmission of certain individually identifiable information. In addition, numerous other federal and state laws, including state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, govern the collection, use, disclosure and security of personal information.

Various foreign countries also have, or are developing, laws governing the collection, use, disclosure, security, and cross-border transmission of personal information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to affect our business. For example, privacy requirements in the European Union (“EU”) govern the transfer of personal information from the European Economic Area to the United States. While we continue to address the implications of changes to the EU data privacy regulations, the area remains an evolving landscape with new regulations coming into effect and continued legal challenges and our efforts to comply with the evolving data protection rules may be unsuccessful. Failure to comply with laws regarding data protection would expose us to risk of enforcement actions taken by data protection authorities in the EU and the potential for significant penalties if we are found to benon-compliant. Similarly, failure to comply with federal and state laws in the United States regarding privacy and security of personal information could expose us to penalties under such laws. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our business.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Repligen and its subsidiaries, collectively doing business as Repligen Corporation (“Repligen”, the “Company”“we”, “we”“our”, or “our”“the Company”) is a bioprocessing-focused,leading provider of advanced bioprocessing technology and solutions used in the process of manufacturing biologic drugs. Our products are made to substantially increase biopharmaceutical manufacturing efficiencies and flexibility. As the global life sciences company bringing over 30 years of expertisebiologics market continues to experience strong growth and innovationexpansion, our customers – primarily large biopharmaceutical companies and contract manufacturing organizations – face critical production cost, capacity, quality and time pressures that our products are made to address. Our commitment to bioprocessing is helping set new standards for the way our customers. Our mission iscustomers manufacture biologic drugs – including monoclonal antibodies, recombinant proteins, vaccines and gene therapies. We are dedicated to inspire“inspiring advances in bioprocessingbioprocessing” as a trusted partner in the production of biologic drugs that improve human health worldwide. Focused on cost and process efficiencies,

Our Chromatography products featurepre-packed chromatography columns under our OPUS® brand. OPUS columns, which we deliver innovative technologiesto our customerspre-packed with their choice of chromatography resin, are single-campaign(“single-use”) disposable columns that help set new standardsreplace the use of traditional (more permanent) glass columns used in the way biologic drugs are manufactured. We develop and market a broad range of high-value productsdownstream purification processes. By designing OPUS as an advanced and flexible solutions that address critical stepsoption for the purification of biologics from process development through clinical-scale and some commercial manufacturing, Repligen has become a leader in the productionpre-packed columns.

Our Filtration products offer a number of advantages to manufacturers of biologic drugs – principally antibody-based therapeutics,at volumes that span from pilot studies to clinical and commercial-scale production. XCell ATF systems are used primarily in upstream perfusion (“continuous manufacturing”) processes to increase cell concentration and significantly improve biologic product yield from a bioreactor. To address increasing industry demand for“plug-and-play” technology, we developed and in 2016 launchedsingle-use formats of the original stainless steel XCell ATF device. In December 2016, we acquired TangenX Technology Corporation (“TangenX”), balancing our upstream XCell ATF offering with a downstream portfolio of flat-sheet filters and cassettes used in biologic drug purification and formulation processes. The TangenX portfolio includes thesingle-use SIUS TFF brand, providing customers with a high-performance,low-cost alternative to reusable TFF products. In August 2017, we completed our acquisition of Spectrum. Spectrum brands include the KrosFlo® family of products, ProConnex® disposable flow-path products, TFF systems and others. The Spectrum acquisition significantly strengthened our Filtration product line and diversifies our end markets beyond mAbs to include vaccine, recombinant proteinsprotein and vaccines – while ensuring that the highest drug qualitygene therapies.

We are a leading OEM manufacturer and safety standards are upheld.

Since our strategic decision in 2012 to focus fully on building our bioprocessing business, we have expanded and diversified our portfolio beyond our legacysupplier of Protein A affinity ligands business to include a number of technology leading bioprocessing products that we sell direct to biopharmaceutical companies and CDMOs (contract development and manufacturing organizations) worldwide. Our dedicated team of professionals has substantial experience in biomanufacturing and works proactively with industry leaders and customers to develop innovative solutions that address pressure points in the bioproduction process.

Our bioprocessing products drive process efficiency, cost and yield improvements. In upstream processes, our XCell™ ATF filtration devices and protein cell culture supplements are used in clinical and commercial-stage manufacturing to improve biologic drug yields. In downstream processes, ourlife sciences companies. Protein A ligands are a criticalan essential “binding” component of Protein A resins used to purify over 50 antibody-based drugs on the market and more than 350 in clinical development. Also in downstream processes, our OPUS pre-packed chromatography columns (PPCs) areresins used in the purification of clinical-stage biologics, andvirtually all monoclonal antibody (“mAb”) based drugs on the market or in development that our Sius™ TFF filtration cassettes are used to concentrate clinical and commercial-stage biologic drugs.

We manufacture and supply Protein A ligands through long-term agreements with major life sciences companies, such as GE Healthcare and MilliporeSigma, who in turn produce andcustomers sell Protein A resins to end users (biopharmaceutical companies and CDMOs).manufacturers) for use in downstream purification of mAbs. We also manufacture and supply oursell growth factor products used to supplement cell culture supplements through a distribution agreement with MilliporeSigma.

We market our chromatography and filtration products globally through a direct commercial organizationmedia in the United States and Europe with a combination of direct sales and distributors in Asia. Since 2014, we have invested in expanding our global commercial organization adding 30 sales, marketing, product management, service and applications personnel to form a 37-person commercial team. Our commercial and R&D teams have a track record of successfully launching new products and applications, as well as building new markets for acquired technologies. For example, since acquiring the XCell ATF business in 2014, we have rapidly expanded its market penetration through increased customer interaction, new products and expanded applications that increase flexibility and convenience while streamlining biomanufacturing workflow for our customers.

Our portfolio of bioprocessing products has expanded from our legacy Protein A line since 2011 through strategic acquisitions and internal product development. We have focused on building a portfolio of technology-leading products that we sell directly to end users. In 2016, we added the Sius TFF filtration line through our purchase of TangenX Technology Corporation (“TangenX”), and we added a lab-scale pre-packed chromatography column line through our purchase of Atoll GmbH. In 2014, we acquired the XCell ATF filtration line from Refine Technologies LLC. In 2011, we added to our Protein A ligands business and added cell culture growth factors through our acquisition of Novozymes Biopharma Sweden AG. Internally, we developed and market our process-scale OPUS pre-packed chromatography columns. Also through internal innovation, we have extended both our OPUS and XCell ATF product lines, to include more size options and technology features to benefit our customers. For example in 2016 we introduced a resin recovery feature on our largest OPUS columns (OPUS R) and we launched a single-use (disposable) alternative to our stainless steel XCell ATF Systems.

Many of our products are early in their adoption cycle and, together with the expansion of our commercial organization and strategic acquisitions, have contributed to product revenue expansion from $41.8 million in 2012 to $104.5 million in 2016. While all product franchises have grown, our diversification strategy has resulted in our direct product sales accounting for approximately 50% of our bioprocessing revenue in 2016, compared to approximately 20% in 2012. To meet increased demand for our products, we have increased and continueorder to increase the volumecell growth and scale of manufacturing at our two manufacturing facilitiesproductivity in the United States and Sweden and plan to expand manufacturing capacity at our newly acquired manufacturing facilities in the United States and Germany.a bioreactor.

Customers use our products to produce initial quantities of drug for clinical studies and thenscale-up to larger volumes as the drug progresses to commercial production following regulatory approval. Detailed specifications for a drug’s manufacturing process are included in the applications that must be approved bybiopharmaceutical companies file for marketing approval with regulators, such as the U.S. Food and Drug Administration (“FDA”) and the European Medicines Agency, throughout the clinical trial process and prior to final commercial approval. As a result, products that become part of the manufacturing specifications of a late-stage clinical or commercial process can be very “sticky” due tosensitive given the costs and uncertainties associated with displacing them.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical Accounting Policies and Estimates

While our significant accounting policies are more fully described in the notes to our consolidated financial statements, we have identified the policies and estimates below as being critical to our business operations and the understanding of our results of operations. The impact of and any associated risks related to these policies on our business operations are discussed throughout “Management’s Discussion and Analysis of Financial Condition,” including in the “Results of Operations” section, where such policies affect our reported and expected financial results.

Revenue recognition

Product Sales

We generate revenue from the sale of bioprocessing products, equipment devices, and related consumables used with these equipment devices to customers in the life science and biopharmaceutical industries. On product sales to end customers, Under ASC 606, “Revenue from Contracts with Customers,”revenue is recognized netwhen, or as, obligations under the terms of discounts,a contract are satisfied, which occurs when bothcontrol of the titlepromised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method or the most likely amount method, depending on the facts and riskcircumstances relative to the contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of loss have transferredcumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of December 31, 2018.

Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes product revenue under the terms of each customer agreement upon transfer of control to the customer, as determined by the shipping terms provided there are no uncertainties regarding acceptance, and all obligations have been completed. Generally, our product arrangements for equipment sales are multiple element arrangements, and may include services, such as installation and training, and multiple products, such as consumables and spare parts. In accordance with ASC 605-25, based on terms and conditions of the product arrangements, the Company believes that these services and undelivered products can be accounted for separately from the delivered product element as the delivered products have value to our customers onwhich occurs at a standalone basis. Accordingly, revenue for services not yet performed at the time of product shipment are deferred and recognized as such services are performed. The relative selling price of any undelivered products is also deferred at the time of shipment and recognized as revenue when these products are delivered. For product sales to distributors, the Company recognizes revenue for both equipment and consumables upon delivery to the distributors unless direct shipment to the end user’s is requested. In this case, revenue is recognized upon delivery to the end user’s location. In general, distributors are responsible for shipment to the end customer along with installation, training and acceptance of the equipment by the end customer. Shipments to distributors are not contingent upon resale of the product. We have a few longstanding customers who comprise the majority of revenue and have excellent payment histories and therefore we do not require collateral. We have had no significant write-offs of uncollectible invoicespoint in the periods presented.

At the time of sale, we also evaluate the need to accrue for warranty and sales returns. The supply agreements we have with our customers and related purchase orders identify the terms and conditions of each sale and the price of the goods ordered. Due to the nature of the sales arrangements, inventory produced for sale is tested for

quality specifications prior to shipment. Since the product is manufactured to order and in compliance with required specifications prior to shipment, the likelihood of sales return, warranty or other issues is largely diminished. Furthermore, there is no customer right of return in our sales agreements. Sales returns and warranty issues are infrequent and have not had a material impact on our financial statements historically.

Shipping and handling fees are recorded as a component of product revenue, with the associated costs recorded as a component of cost of product revenue.

Pfizer License Agreement

In December 2012, we entered into an exclusive worldwide licensing agreement (the “License Agreement”) with Pfizer, Inc. (“Pfizer”) to advance the SMA program, which is led by RG3039 and also includes backup compounds and enabling technologies. Under the terms of the License Agreement, we received $5 million from Pfizer as an upfront payment on January 22, 2013, a $1 million milestone payment on September 4, 2013 and a $1 million milestone payment on December 28, 2014. On January 26, 2015, Pfizer sent us a termination notice, and the License Agreement expired on April 25, 2015. On March 17, 2016, we terminated our licensing agreement with CureSMA and returned all patent rights and related data and materials to CureSMA.

BioMarin License Agreement

On January 21, 2014, we out-licensed our histone deacetylase inhibitor (“HDACi”) portfolio, which includes the Friedreich’s ataxia program, to BioMarin Pharmaceuticals Inc. (“BioMarin”). Under the terms of the agreement, we received an upfront payment of $2 million in January 2014 from BioMarin and a $125,675 payment in September 2014 upon tech transfer, and we have the potential to receive up to $160 million in future milestone payments for the development, regulatory approval and commercial sale of portfolio compounds included in the agreement. In addition, we are eligible to receive royalties on sales of qualified products developed.time.

Inventories

Inventories relate to our bioprocessing business. We value inventory at cost or, if lower, fair marketnet realizable value, using thefirst-in,first-out method. We review our inventory at least quarterly and record a provision for excess and obsolete inventory based on our estimates of expected sales volume, production capacity and expiration dates of raw materials,work-in-process and finished products. Expected sales volumes are determined based on supply forecasts provided by key customers for the next three to 12 months. We write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements to cost of product revenue. Manufacturing of bioprocessing finished goods is done to order and tested for quality specifications prior to shipment.

A change in the estimated timing or amount of demand for our products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on the value of inventory and reported operating results. During all periods presented in the accompanying consolidated financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

Business combinations

Amounts paid for acquisitions are allocated to the assets acquired and liabilities assumed, if any, based on their fair values at the dates of acquisition. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions determined by management. Any excess of purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. The fair value of contingent consideration includes estimates and judgments made by management regarding the probability that future contingent payments will be made, the extent of royalties to be earned in excess of the defined minimum

royalties, etc. Management updates these estimates and the related fair value of contingent consideration at each reporting period based on the estimated probability of achieving the earnout targets and applying a discount rate that captures the risk associated with the expected contingent payments. To the extent our estimates change in the future regarding the likelihood of achieving these targets we may need to record material adjustments to our accrued contingent consideration. Changes in the fair value of contingent consideration are recorded in our consolidated statement of operations. We have accrued approximately $6.1 million as of December 31, 2016 related to sales targets as part of the Refine Acquisitionoperations and the Atoll Acquisition.comprehensive income.

We use the income approach to determine the fair value of certain identifiable intangible assets including customer relationships and developed technology. This approach determines fair value by estimatingafter-tax cash flows attributable to these assets over their respective useful lives and then discounting theseafter-tax cash flows back to a present value. We base our assumptions on estimates of future cash flows, expected growth rates, expected trends in technology, etc. We base the discount rates used to arrive at a present value as of the date of acquisition on the time value of money and certain industry-specific risk factors. We believe the estimated purchased customer relationships, developed technologies, trademark / tradename, patents, and in process research and development amounts so determined represent the fair value at the date of acquisition and do not exceed the amount a third party would pay for the assets.

Intangible assets and goodwill

Intangible Assetsassets

We amortize our intangible assets that have finite lives using the straight-line method. Amortization is recorded over the estimated useful lives ranging from 2 to 20 years. We review our intangible assets subject to amortization to determine if any adverse conditions exist or a change in circumstances has occurred that would indicate impairment or a change in the remaining useful life. Further, we also review our indefinite-lived intangible assets not subject to amortization to determine if any adverse conditions exist or a change in circumstances occurred that would indicate an impairment. If the carrying value of an asset exceeds its estimated undiscounted cash flows, we will write-down the carrying value of the intangible asset to its fair value in the period identified. In assessing fair value, we must make assumptions regarding estimated future cash flows and discount rates. If these estimates or related assumptions change in the future, we may be required to record impairment charges. We generally calculate fair value as the present value of estimated future cash flows to be generated by the asset using a risk-adjusted discount rate. If the estimate of an intangible asset’s remaining useful life is changed, we will amortize the remaining carrying value of the intangible asset prospectively over the revised remaining useful life.

Goodwill

We test goodwill for impairment on an annual basis and between annual tests if events and circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. Events that

would indicate impairment and trigger an interim impairment assessment include, but are not limited, to current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate or operational performance of the business, and an adverse action or assessment by a regulator. Our annual impairment test date is the last day of our fiscal year, December 31 2016. The Company performed itsst. While we currently operate as one operating segment, we perform our annual impairment test over each of the Company’s onetwo reporting unitunits and concluded that goodwill was not impaired.

Accrued liabilities

We estimate accrued liabilities by identifying services performed on our behalf, estimating the level of service performed and determining the associated cost incurred for such service as of each balance sheet date. For example, we would accrue for professional and consulting fees incurred with law firms, audit and accounting

service providers and other third partythird-party consultants. These expenses are determined by either requesting those service providers to estimate unbilled services at each reporting date for services incurred or tracking costs incurred by service providers under fixed fee arrangements.

We have processes in place to estimate the appropriate amounts to record for accrued liabilities, which principally involve the applicable personnel reviewing the services provided. In the event that we do not identify certain costs that have begun to be incurred or we under or over-estimate the level of services performed or the costs of such services, the reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services often require the exercise of judgment. We make these judgments based upon the facts and circumstances known at the date of the financial statements.

A change in the estimated cost or volume of services provided could result in additional accrued liabilities. Any significant unanticipated changes in such estimates could have a significant impact on our accrued liabilities and reported operating results. There have been no material adjustments to our accrued liabilities in any of the periods presented in the accompanying consolidated financial statements.

Stock-based compensation

We use the Black-Scholes option pricing model to calculate the fair value of share-based awards on the grant date.

The expected term of options granted represents the period of time for which the options are expected to be outstanding and is derived from our historical stock option exercise experience and option expiration data. For purposes of estimating the expected term, we have aggregated all individual option awards into one group, as we do not expect substantial differences in exercise behavior among our employees. The expected volatility is a measure of the amount by which our stock price is expected to fluctuate during the expected term of options granted. We determined the expected volatility based upon the historical volatility of our common stock over a period commensurate with the option’s expected term. The risk-free interest rate is the implied yield available on U.S. Treasuryzero-coupon issues with a remaining term equal to the option’s expected term on the grant date. We have never declared or paid any cash dividends on any of our capital stock and do not expect to do so in the foreseeable future. Accordingly, we use an expected dividend yield of zero to calculate the grant-date fair value of a stock option.

We recognize compensation expense on awards that vest based on service conditions on a straight-line basis over the requisite service period based upon the number of options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted by an amount of estimated forfeitures. We recognize compensation expense on awards that vest based on performance conditions based on our assessment of the probability that the performance condition will be achieved over the service period. Forfeitures represent only the unvested portion of a surrendered option. Forfeitures are estimated at the time of grant and revised, if necessary,

in subsequent periods if actual forfeitures differ from those estimates. Based on an analysis of historical data, we have calculated an 8% annual forfeiture rate fornon-executive level employees, a 3% annual forfeiture rate for executive level employees, and a 0% forfeiture rate fornon-employee members of the Board of Directors, which we believe are reasonable assumptions to estimate forfeitures. However, the estimation of forfeitures requires significant judgment and, to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.

For the fiscal years ended December 31, 2016, 20152018, 2017 and 2014,2016, we recorded stock-based compensation expense of approximately $4,595,000, $3,598,000$10.2 million, $6.7 million and $1,766,000,$4.6 million, respectively, for share-based awards granted under all of the Company’s stock plans.

As of December 31, 2016,2018, there was $9,555,000$27.1 million of total unrecognized compensation cost related to unvested share-based awards. This cost is expected to be recognized over a weighted average remaining requisite service period of 2.974.53 years. We expect 719,5791,195,236 unvested options and restricted stock unitsRSUs to vest over the next five years.

Income Taxestaxes

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided, if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. We account for uncertain tax positions using a “more-likely-than-not”“more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. We evaluate our tax position on a quarterly basis. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense.

Product revenues

Historically, the majority of our bioprocessing products are sold to customers who incorporate our products into their proprietary antibody purification processes for monoclonal antibodies. These customers then sell their products directly to the pharmaceutical industry. Increasingly,Since 2016, we arehave been increasingly focused on selling our products directly to customers in the pharmaceutical industry and to our its contract manufacturers. These direct sales have increased to approximately 52%72% of our product revenue during fiscal 2016.2018. We expect that direct sales will continue to account for an increasing percentage of our product revenues. Sales of our bioprocessing products can be impacted by the timing of large-scale production orders and the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations.

For fiscal 2016, bioprocessing2018, product salesrevenue increased by $20,904,000$52.8 million, or 25%37%, as compared to fiscal 2015,2017. The increase is due to the continued adoption of our products by our key bioprocessing customers and a full year of revenues derived from our acquisition of Spectrum in August 2017. Sales of our bioprocessing products are impacted by the timing of orders, development efforts at our customers orend-users and regulatory approvals for biologics that incorporate our products, which may result in significant quarterly fluctuations. Such quarterly fluctuations are expected, but they may not be predictive of future revenue or otherwise indicate a trend.

For 2017, product revenues increased by $36.6 million, or 35%, as compared to 2016. The increase in product revenues is due largely to increased volumes in our Filtration and Chromatography products, as well asfull year of revenue generated from Atoll and TangenX in 2017, and revenues of $19.4 million generated from the Atoll Acquisition. We sell our various bioprocessing products at different price points.

Royalty revenues

We recognized $2,126,000 of revenue for fiscal 2014Royalty revenues in 2018 and 2017 relate to royalties received from the out-license ofa third-party systems manufacturer associated with our HDACi portfolio to BioMarinOPUS PD chromatography columns. Royalty revenues are variable and are dependent on January 21, 2014. We also recognized $1,000,000 of revenue for fiscal 2014 from the out-license ofsales generated by our Spinal Muscular Atrophy program to Pfizer on December 28, 2012. We did not recognize any such revenue in fiscal 2015 and 2016, and we do not expect to recognize any research and license revenue or to receive any incremental funding for our therapeutic development programs going forward.partner.

Cost of product revenue

For fiscal 2016,2018, cost of product revenue increased $11,866,000$19.5 million, or 34%29%, as compared to fiscal 2015.2017 due primarily to the increase in product revenue mentioned above. Gross margins may fluctuate in future quarters based on expected production volume and product mix. For 2017, cost of product revenue increased $19.9 million, or 42% as compared to 2016. This increase is primarily due to the increase in product revenues noted above. For fiscal 2015,above, the sale of higher cost of product revenue increased $7,229,000 or 26% as compared to fiscal 2014. This increase is primarilySpectrum finished goods inventory due to the increased product revenue noted above.step up to fair value upon acquisition, and costs related to continuing investments in our operations to support future growth.

Gross margins were 55%, 58%53%, and 54%55% for fiscal2018, 2017 and 2016, 2015, and 2014, respectively. During fiscal 2016,2018, gross margins decreasedincreased compared to 2017 primarily due to higher product revenue. During 2017, gross margins declined slightly compared to fiscal 20152016 due to product mix, the sale of higher cost Spectrum finished good inventory due to step up to fair value upon acquisition and increasedcontinuing investments in operations to support growing demands for the bioprocessing products that we manufacture. During fiscal 2015, gross margins increased slightly compared to fiscal 2014 due to increased capacity utilization and product mix.future growth.

Research and development expenses

During fiscal2018, 2017 and 2016, 2015 and 2014, research and development expenses were related to bioprocessing products which included personnel, supplies and other research expenses. In August 2012, we announced a strategic focus on our Bioprocessing business and a simultaneous effort to find partners, out-licensing opportunities or other funding arrangements with external parties to reduce or eliminate the net expenditures on research and development activities for our therapeutic programs. In January 2013, we announced that we entered into an outlicensing agreement with Pfizer, Inc. for our Spinal Muscular Atrophy program, under an arrangement that would provide $5.0 million up front and up to $65.0 million in milestone payments, plus royalties. On January 26, 2015, Pfizer notified us that they were terminating this arrangement for convenience effective as of April 26, 2015. In January 2014, we announced that we entered into an outlicensing agreement with BioMarin Pharmaceutical Inc. for our Friedreich’s ataxia portfolio, under an arrangement that would provide $2.0 million up front and up to $160.0 million in future milestones, plus royalties.

Due to the small size of the Company and the fact that these various programs share personnel and fixed costs, we do not track all of our expenses or allocate any fixed costs by program, and therefore, have not provided an estimate of historical costs incurred by project. In addition to the legacy product research and development, the currentsingle-use XCell ATF project incurs expenses related to product development, sterilization, validation testing, and other research related expenses.

For fiscal 2016,2018, research and development expenses increased by $1,615,000$7.1 million, or 28%82%, as compared to fiscal 2015.2017. This increase is primarily driven by investments made during 2018 to expand our proteins product offerings through our development agreement with Navigo Proteins GmbH (“Navigo”). Additionally, the increase is related to product development activities acquired as part of the Spectrum acquisition and increased activity in our various bioprocessing development projects.

For 2017, research and development expenses increased by $1.3 million, or 18% as compared to 2016. This increase is related to the increased expenditures related to the continued development of our single usesingle-use XCell ATF products our OPUS resin recovery port, and other new products in development. Expenditures in 2016 included personnel, supplies and other external development, expenses.

For fiscal 2015, research and developmentas well as expenses increasedincurred by $131,000 or 2% as compared to fiscal 2014. This increase is primarily related to the timing of expenditures, including personnel, supplies and other development expenses related to our new products in development.Spectrum since acquisition.

We expect our research and development expenses in the year ending December 31, 2017, which relate to bioprocessing product development,2019 to increase moderately.in order to support new product development.

Selling, general and administrative expenses

Selling, general and administrative (“SG&A”) expenses include the costs associated with selling our commercial products and costs required to support our marketing efforts, including legal, accounting, patent, shareholder services, amortization of intangible assets and other administrative functions.

For fiscal 2016,2018, SG&A costs increased by $6,154,000$14.2 million, or 25%28%, as compared to fiscal 2015.2017. The increase is due to selling and administrative activities incurred following the Spectrum acquisition, as well as the continued buildout of our administrative infrastructure to support expected future growth and continued expansion of our customer-facing activities to drive sales of our bioprocessing products.

For 2017, SG&A costs increased by $20.7 million, or 67%, as compared to 2016. This increase is primarily due to costs related to our acquisition of Spectrum, the continuing buildout of our administrative infrastructure to support future growth, the continuing expansion of our customer-facing activities to drive sales of our bioprocessing products, a full year of costs related to the Atoll Acquisition and TangenX Acquisition and expensescosts incurred by Repligen GmbH (formerly Atoll) post-acquisition.

For fiscal 2015, SG&A costs increased by $7,545,000 or 44% as compared to fiscal 2014. This increase is primarily due to higher administrative expenses related to the implementation of an inventory accounting software package, the buildout of our administrative infrastructure to support future growth and the expansion of our customer-facing activities to drive sales of our bioprocessing products. This increase is partially offset by $818,000 of closing and transition costs incurred in 2014 related to the Refine Acquisition.Spectrum since acquisition.

Contingent Considerationconsideration

For fiscal 2016, our contingent consideration liability decreased approximately $669,000 compared to fiscal 2015. In fiscal 2016, we recorded contingent consideration expense related primarily to theour acquisitions of Refine Acquisition

and the Atoll Acquisition.Atoll. Contingent consideration related to the Refine Acquisition in 2016 is based on actual 2016 XCell ATF sales and any receipts related to the resolution, withdrawal or settlement of certain patent disputes with a third party to be paid to the former shareholders of Refine. Contingent consideration related to Atoll is based on actual 2016 sales growth compared to 2015 sales. The decrease is attributable to recording Refine contingent consideration fair value adjustments related to projected 2015 and 2016 XCell ATF sales in the previous year, while in 2016 we only recorded fair value adjustments related to 2016 sales. This decrease is partially offset by contingent consideration expense related to the Atoll Acquisition.our acquisition of Atoll. Because the contingent consideration periods related to theour acquisitions of BioFlash, Refine and Atoll acquisitions all concluded in 2016, we dodid not expect to incur any contingent consideration expense in 2017.

For fiscal 2015,Other expenses, net

The table below provides detail regarding our contingent consideration liability increased approximately $2,943,000 compared to fiscal 2014. The contingent consideration for this period stems from the BioFlash and Refine acquisitions. The increase is primarily attributed to a $4,048,000 increase in the fair value of the contingent consideration stemming from the Refine acquisition, partially offset by payments of approximately $1,139,000 to Refine and BioFlash. The contingent consideration related to BioFlash is valued using management’s estimates of royalties to be paid to the former shareholders of BioFlash based on sales of the acquired assets. The contingent consideration related to the Refine Acquisition is valued using management’s estimates of expected future milestone payments based on forecasted sales of the acquired assets and portion of any receipts that might be received in connection with the resolution, withdrawal or settlement of certain patent disputes with a third party to be paid to the former shareholders of Refine.other expenses, net:

Investment income

Investment income includes income earned on invested cash balances. Investment income for fiscal 2016, 2015, and 2014 was $346,000, $136,000, and $309,000, respectively. The increase of $210,000$1.5 million for 2018, as compared to 2017 was attributable to higher average invested cash balances and higher interest rates on such invested cash balances. The increase of approximately $25,000, or 154%7%, for fiscal 20162017 was primarily due to higher invested funds following the issuance of our convertible senior notesinterest rates during 20162017 compared to 2015. The decrease of $173,000 or 56% for fiscal 2015 was primarily due to lower invested funds during 2015 compared to 2014.2016. We expect investment income to vary based on changes in the amount of funds invested and fluctuation of interest rates.

Interest expense

Interest expense primarily relates to interest related to our issuance of 2.125% Convertible Senior Notes due 2021 (the “Notes”) in May 2016. Interest expense increased $0.3 million in 2018, as compared to 2017 due to the

decrease in the balance of debt issuance costs that are being amortized. As these costs decrease the carrying value of the debt increases and interest calculated based on the carrying value increases as well. The increase of $2.7 million in 2017, as compared to 2016 was due to incurring a full year of interest expense on the Notes in 2017.

Other expenses

Changes in other expense in 2018, compared to the corresponding periods in the prior year are primarily attributable to foreign currency gains related to amounts due fromnon-Swedish kronor-based customers and cash balance denominated in U.S. dollars and British pounds held by Repligen Sweden AB.

Provision (benefit) for income taxes

TheIncome tax provision (benefit) for income taxes forthe years ended December 31, 2018, 2017 and 2016 was as follows:

For the year ended December 31, 2016 totaled $11,000. Our current2018, we recorded an income tax provision of $4,077,000$4.8 million. The effective tax rate was 22.5% in 2018 and is based upon the estimated income from the year and the composition of the income in different jurisdictions. The effective tax rate was higher than the U.S. statutory rate of 21% due to state tax effects and the impact of the Global IntangibleLow-Taxed Income tax enacted as part of the Tax Cuts and Jobs Act (the “2017 Tax Act”) enacted in December 2017.

For the year ended December 31, 2017, we recorded an income tax benefit of ($21.1) million. This income tax benefit was composed of current income tax provision of $3.6 million, offset by ($24.7) million deferred tax benefit. The 2017 tax provision of $3.6 million primarily relates to a foreign tax provision of $4,027,000.$3.3 million. Our deferred tax benefit of ($4,066,000)24.7) million is primarily due to a reduction of the valuation allowance on our deferred tax assets in the amount of $8,535,000 resulting$12.2 million from the sale of certain intellectual property to Repligen Sweden AB during 2017 and taxable temporary differences generated from the TangenX Acquisition andSpectrum acquisition. Additionally, the issuanceCompany recorded a deferred tax benefit of our convertible senior notes, partially offset by an increase in$12.8 million resulting from a reduction of the U.S. federal income tax on the Company’s net U.S. deferred tax liabilities related tostemming from new U.S. federal tax amortization of indefinite lived intangibles and the conversion option on our convertible senior notes.legislation passed in December 2017.

The provision for income taxes for the year ended December 31, 2015 totaled $4,078,000. Our current tax provision of $3,745,000 primarily relates to a foreign tax provision of $3,507,000 and $315,000 related to the resolution of our uncertain tax position for historic research and development credits and certain state apportionment matters. Our deferred tax provision of $333,000 is primarily due to an increase in deferred tax liabilities related to tax amortization of indefinite lived intangibles.

In June 2015, we received a final assessment from the Massachusetts Department of Revenue (“DOR”) regarding an examination for the years ended March 31, 2010 and 2011 and the nine months ended December 31, 2011. This examination related to the qualification of Research and Development tax credits. The final settlement resulted in a payment to the DOR of approximately $141,000.

In December 2015, we reached a negotiated settlement with the DOR regarding an appeal of an assessment made in 2013 for the years ended March 31, 2008 and 2009. The primary issues in the appeal related to the sourcing of intellectual property settlements and the qualification of Research and Development tax credits. The final settlement resulted in a payment to the DOR of approximately $1,012,000.

Non-GAAP Financial Measures

We providenon-GAAP adjusted income from operations,non-GAAP adjusted net income and adjusted EBITDA as supplemental measures to GAAP measures regarding our operating performance. These financial measures exclude the impact of certain acquisition related items and, therefore, have not been calculated in accordance with GAAP. A detailed explanation and a reconciliation of eachnon-GAAP financial measures to its most comparable GAAP financial measures are described below.

We include this financial information because we believe these measures provide a more accurate comparison of our financial results between periods and more accurately reflect how management reviews its financial results. We excluded the impact of certain acquisition related items because we believe that the resulting charges do not accurately reflect the performance of our ongoing operations for the period in which such charges are incurred.

Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue.

At December 31, 2016,2018, we had cash and cash equivalents of $193.8 million compared to cash, cash equivalents and marketable securities of $141,780,000 compared to $73,407,000$173.8 million at December 31, 2015. In fiscal 2016 we utilized $8,767,000 of cash (net of cash received) in the Atoll Acquisition and $35,847,000 of cash (net of cash received) in the TangenX Acquisition.2017. A deposit for our leased office spacein Waltham, Massachusetts of $450,000 is$0.5 million was classified as restricted cash and iswas not included in cash and marketable securities totals for December 31, 2016 or2016.

The total proceeds from this offering, net of underwriting discounts, commissions and other offering expenses, totaled $129.3 million.

On AprilAugust 1, 2016, pursuant to the terms2017, we completed our acquisition of a Share Purchase Agreement dated as of March 31, 2016, Repligen Sweden AB, our wholly-owned subsidiary, acquired Atoll from UV-Cap GmbH & Co.

The Share Purchase Agreement includes a future contingent payment by Repligen Sweden to the Seller consisting of €1.0 million ($1.1 million) in cash if Atoll’s revenue increases by a specified amount from calendar year 2015 to calendar year 2016.

On May 24, 2016, we received net proceeds of $111,070,000 from the issuance of our 2.125% Convertible Senior Notes due 2021 (the “Notes”). The Notes bear interest at the rate of 2.125% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2016.

The Notes will mature on June 1, 2021, unless earlier repurchased, redeemed or converted in accordance with their terms. Prior to March 1, 2021, the Notes will be convertible at the option of holders of the Notes only upon satisfaction of certain conditions and during certain periods, and thereafter, the Notes will be convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date.

The table excludes a liability for uncertain tax positions totaling $2.9 million since we cannot currently make a reliable estimate of the period in which the liability will be payable, if ever. Please see Note 7,“Income Taxes,”to our consolidated financial statements for more information.

Capital requirementsRequirements

Our future capital requirements will depend on many factors, including the following:

 

the expansion of our bioprocessing business;

 

the ability to sustain sales and profits of our bioprocessing products;

 

our ability to acquire additional bioprocessing products;

 

our ability to realize value from our outlicensed early stage CNS programs and the RG1068 program;

the scope of and progress made in our research and development activities;

 

the extent of any share repurchase activity; and

 

the success of any proposed financing efforts.

Absent acquisitions of additional products, product candidates or intellectual property, we believe our current cash balances are adequate to meet our cash needs for at least the next 24 months. We expect operating expenses

in the year ending December 31, 20172019 to increase as we continue to expand our bioprocessing business. We expect to incur continued spending related to the development and expansion of our bioprocessing product lines and expansion of our commercial capabilities for the foreseeable future. Our future capital requirements may include, but are not limited to, purchases of property, plant and equipment, the acquisition of additional bioprocessing products and technologies to complement our existing manufacturing capabilities, and continued investment in our intellectual property portfolio.

We plan to continue to invest in our bioprocessing business and in key research and development activities associated with the development of new bioprocessing products. We actively evaluate various strategic transactions on an ongoing basis, including licensing or acquiring complementary products, technologies or businesses that would complement our existing portfolio. We continue to seek to acquire such potential assets that may offer us the best opportunity to create value for our shareholders. In order to acquire such assets, we may need to seek additional financing to fund these investments. If our available cash balances and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, including because of any such acquisition-related financing needs or lower demand for our products, we may seek to sell common or preferred equity or convertible debt securities, enter into a credit facility or another form of third-party funding, or seek other debt funding. The sale of equity and convertible debt securities may result in dilution to our stockholders, and those securities may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. We may require additional capital beyond our currently anticipated amounts. Additional capital may not be available on reasonable terms, if at all.

Net operating loss carryforwardsOperating Loss Carryforwards

At December 31, 2016,2018, we had utilized our remaining $19.5 million of net operating loss carryforwards of approximately $48,550,000 andcarryforwards. We had business tax credits carryforwards of approximately $2,187,000$2.9 million available to reduce future federal income taxes, if any. The net operating loss and business tax credits carryforwards will continue to expire at various dates through December 2036.2038. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service, state and foreign jurisdictions and may be limited in the event of certain changes in the ownership interest of significant stockholders.

Foreign earningsEarnings

As of December 31, 2018, the Company has accumulated undistributed earnings generated by our foreign subsidiaries of approximately $72.4 million. Because $58.0 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the 2017 Tax Act, any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of our foreign investments would generally be limited to foreign and state taxes. At December 31, 2016,2018, we have not provided for U.S. income taxes or foreign withholding taxes on outside basis differences of our foreign subsidiaries, of approximately $43,679,000 as we have the ability and intent to indefinitely reinvest the undistributed earnings of Repligen Sweden, Repligen GmbH and Repligen Singapore Pte. Ltd.,our foreign subsidiaries, and there are no needs for such earnings in the U.S.United States that would contradict our plan to indefinitely reinvest.

Effects of inflationInflation

Our assets are primarily monetary, consisting of cash, cash equivalents and marketable securities. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture and fixtures and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate riskRate Risk

We have historically held investments in commercial paper, U.S. Government and agency securities as well as corporate bonds and other debt securities. As a result, we arehave been exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer or otherwise. We do not have any such investments as of December 31, 2018. As a result, a hypothetical 100 basis point increase in interest rates would have no effect on our cash position as of December 31, 2018.

We generally place our marketable security investments in high quality credit instruments, as specified in our investment policy guidelines. A hypothetical 100 basis point increase in interest rates would result in an approximate $64,000 decrease in the fair value of our investments as of December 31, 2016. We believe however, that the conservative nature of our investments mitigates our interest rate exposure, and our investment policy limits the amount of our credit exposure to any one issue, issuer (with the exception of U.S. agency obligations) and type of instrument. We do not expect any material loss from our marketable security investments and therefore believe that our potential interest rate exposure is limited.

Foreign exchange riskExchange Risk

CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.

The Company’s management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined inRules 13a-15(e) or15d-15(e) under the Exchange Act and as required by paragraph (b) of Rules13a-15 or

15d-15 under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our principal executive officer and principal financial officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective at the reasonable assurance level.

(b) Report of Management on Internal Control Over Financial Reporting.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined inRule 13a-15(f) and15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles and includes those policies and procedures that:

 

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

 

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

 

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

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016.2018. In making this assessment, management used the criteria established inInternal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO).

Management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Atoll GmbH acquired on April 1, 2016 or TangenX Technology Corporation acquired on December 14, 2016, which are included in the December 31, 2016 consolidated financial statements of Repligen Corporation and constituted $70,569,000 of total assets as of December 31, 2016 and $3,543,000 of revenues for the year then ended.

Subject to the foregoing, based on this assessment, our management concluded that, as of December 31, 2016,2018, our internal control over financial reporting is effective based on those criteria. Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this Annual Report on Form10-K, has issued an attestation report on our internal control over financial reporting as of December 31, 2016.2018.

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

(c) Attestation Report of the Independent Registered Public Accounting Firm.

Our independent registered public accounting firm that audited the financial statements included in this annual report has issued an attestation report on our internal controls over financial reporting. This report appears below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors and Stockholders of Repligen Corporation:

Opinion on Internal Control over Financial Reporting

We have audited Repligen Corporation’s internal control over financial reporting as of December 31, 2016,2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Repligen Corporation’sCorporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and our report dated March 1, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’sCompany’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

As indicated in the accompanying 10-K, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Atoll GmbH acquired on April 1, 2016 or TangenX Technology Corporation acquired on December 14, 2016, which are included in the December 31, 2016 consolidated financial statements of Repligen Corporation and constituted $70,569,000 of total assets as of December 31, 2016 and $3,543,000 of revenues for the year then ended. Our audit of internal control over financial reporting of Repligen Corporation also did not include an evaluation of the internal control over financial reporting of Atoll GmbH or TangenX Technology Corporation.

In our opinion, Repligen Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

As these acquisitions occurred during 2016, the scope of our assessment of our internal control over financial reporting does not include Atoll and TangenX.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors and Stockholders of Repligen Corporation:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Repligen Corporation (the Company) as of December 31, 20162018 and 2015,2017, and the related consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2016. These2018, and the related notes (collectively referred to as the “consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States)statements”). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Repligen Corporationthe Company at December 31, 20162018 and 2015,2017, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2016,2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), Repligen Corporation’sthe Company’s internal control over financial reporting as of December 31, 2016,2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of the Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 23, 2017March 1, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company‘s management. Our responsibility is to express an opinion on the Company‘s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“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 financial statements and the reported amounts of revenues and expenses during the reporting periods.

Significant estimates and assumptions by management affect the Company’s revenue recognition for multiple element arrangements, allowance for doubtful accounts, the net realizable value of inventory, estimated fair value of cost method investments, valuations and purchase price allocations related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets, estimated fair values of intangible assets and goodwill, amortization methods and periods, warranty reserves, certain accrued expenses, stock-based compensation, fair value estimates of contingent consideration, contingent liabilities, tax reserves and recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its

estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.

Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Repligen Sweden AB, Repligen GmbH, TangenX Technology CorporationSpectrum LifeSciences LLC and its subsidiaries (“Spectrum,” acquired on August 1, 2017) and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior year balances have changed to reflect current year presentation.

Foreign Currency

The Company translates the assets and liabilities of its foreign subsidiary at rates in effect at the end of the reporting period. Revenues and expenses are translated at average rates in effect during the reporting period. Translation adjustments, including adjustments related to the Company’s intercompany loan with Repligen Sweden AB and Repligen Sweden’sSweden AB’s intercompany loan with Repligen GmbH, are remeasured at each period end and included in accumulated other comprehensive income.

Revenue Recognition

Product Sales

The Company’sWe generate revenue recognition policy is to recognize revenues from product sales and services in accordance with ASC 605, Revenue Recognition. These standards require that revenues are recognized when persuasive evidence of an arrangement exists, product delivery, including customer acceptance, has occurred or services have been rendered, the price is fixed or determinable and collectability is reasonably assured. Determination of whether these criteria have been met are based on management’s judgments primarily regarding the fixed nature of the fee charged for the product delivered and the collectability of those fees. The Company has a few longstanding customers who comprise the majority of revenue and have excellent payment histories and therefore the Company does not require collateral. The Company has had no significant write-offs of uncollectible invoices in the periods presented. When more than one element such as equipment, consumables, and services are contained in a single arrangement, the Company allocates revenue between the elements based on each element’s relative selling price, provided that each element meets the criteria for treatment as a separate unit of accounting. An item is considered a separate unit of accounting if it has value to the customer on a stand-alone basis. The selling price of the undelivered elements is determined by the price charged when the element is sold separately, or in cases when the item is not sold separately, by third-party evidence of selling price or management’s best estimate of selling price.

The Company’s product revenues are from the sale of bioprocessing products, equipment devices, and related consumables used with these equipment devices to customers in the life science and biopharmaceutical industries. On product sales to end customers, Under ASC 606, “Revenue from Contracts with Customers,”revenue is recognized netwhen, or as, obligations under the terms of discounts,a contract are satisfied, which occurs when bothcontrol of the titlepromised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method or the most likely amount method, depending on the facts and riskcircumstances relative to the contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of loss have transferredcumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of December 31, 2018.

Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes product revenue under the terms of each customer agreement upon transfer of control to the customer, as determined by the shipping terms provided there are no uncertainties regarding acceptance, and all obligations have been completed. Generally, our product arrangements for equipment sales are multiple element arrangements, and may include services, such as installation and training, and multiple products, such as consumables and spare parts. In accordance with ASC 605-25, based on terms and conditions of the product arrangements, the Company believes that these services and undelivered products can be accounted for separately from the delivered product element as the delivered products have value to our customers onwhich occurs at a standalone basis. Accordingly, revenue for services not yet performed at the time of product shipment are deferred and recognized as such services are performed. The relative selling price of any undelivered products is also deferred at the time of shipment and recognized as revenue when these products are delivered. For product sales to distributors, the Company recognizes revenue for both equipment and consumables upon delivery to the distributor unless direct shipment to the end user is requested. In this case, revenue is recognized upon delivery to the end user’s location. In general, distributors are responsible for shipment to the end customer along with installation, training and acceptance of the equipment by the end customer. Sales to distributors are not contingent upon resale of the product.point in time.

At the time of sale, the Company also evaluates the need to accrue for warranty and sales returns. The supply agreements the Company has with its customers and the related purchase orders identify the terms and conditions

of each sale and the price of the goods ordered. Due to the nature of the sales arrangements, inventory produced for sale is tested for quality specifications prior to shipment. Since the product is manufactured to order and in compliance with required specifications prior to shipment, the likelihood of sales return, warranty or other issues is largely diminished. Furthermore, there is no customer right of return in our sales agreements. Sales returns and warranty issues are infrequent and have not had a material impact on the Company’s financial statements historically.

Shipping and handling fees are recorded as a component of product revenue, with the associated costs recorded as a component of cost of product revenue.

The Scripps Research Institute

On April 6, 2007, the Company entered into an exclusive worldwide commercial license agreement (“Scripps License Agreement”) with The Scripps Research Institute (“Scripps”). Pursuant to the License Agreement, the Company obtained a license to use, commercialize and sublicense certain patented technology and improvements thereon, owned or licensed by Scripps, relating to compounds that may have utility in treating Friedreich’s ataxia, an inherited neurodegenerative disease.

Pursuant to the Scripps License Agreement, the Company agreed to pay Scripps an initial license fee of $300,000, certain royalty and sublicense fees and, in the event that the Company achieved specified developmental and commercial milestones, certain additional milestone payments. Total future milestone payments, if all milestones had been achieved, would have been approximately $4,300,000. In addition, the Company issued Scripps and certain of its designees 87,464 shares of the Company’s common stock, which had a value of $300,000 on the date of issuance.

In connection with the Scripps License Agreement, the Company issued warrants to an individual at Scripps to purchase up to 150,000 shares of common stock. No expense was recorded related to these warrants through December 31, 2014, as the vesting of these warrants was contingent upon certain performance conditions that were not satisfied. During the year ending December 31, 2014, the warrant’s seven-year term expired.

As of January 2014, all rights and obligations have been transferred to BioMarin.

Sale of Intellectual Property to BioMarin

In January 2014, the Company entered into an asset purchase agreement (the “Asset Purchase Agreement”) with BioMarin Pharmaceutical Inc. (“BioMarin”) to sell Repligen’s histone deacetylase inhibitor (HDACi) portfolio. Pursuant to the terms of the Asset Purchase Agreement, the Company received $2 million from BioMarin as an upfront payment on January 30, 2014 and a $125,675 payment on September 3, 2014 upon completion of the Technology Transfer. The Company is entitled to receive up to $160 million in potential future milestone payments for the development, regulatory approval and commercial sale of portfolio compounds included in the agreement. These potential milestone payments are approximately 37% related to clinical development and 63% related to initial commercial sales in specific geographies. In addition, Repligen is eligible to receive royalties on sales of therapeutic products originating from the HDACi portfolio. The royalty rates are tiered and begin in the mid-single-digits for the first HDACi portfolio product and for the first non-HDACi portfolio product with lesser amounts for any backup products developed under the Asset Purchase Agreement. Repligen’s receipt of these royalties is subject to customary offsets and deductions. There are no refund provisions in this agreement. The Company recognized $2.1 million of revenue in the fiscal year ended December 31, 2014 related to the transfer of the HDACi technology under the Asset Purchase Agreement. Any milestones earned upon specified clinical development or commercial sales events or future royalty payments, under the Asset Purchase Agreement will be recognized as revenue when they are earned.

Activities under this agreement were evaluated in accordance with ASC 605-25 to determine if they represented a multiple element revenue arrangement. The Company identified the following deliverables in the BioMarin agreement:

The assignment by Repligen to BioMarin of the Repligen Technology (“Repligen Know-How” and “Repligen Patents”) and the Scripps Agreement (the “Transferred Assets”);

The transfer of certain notebooks, data, documents, biological materials (if any) and other such documents in our possession that might be useful to further development of the program (the “Technology Transfer”).

Two criteria must be met in order for a deliverable to be considered a separate unit of accounting. The first criterion requires that the delivered item or items have value to the customer on a stand-alone basis. The second criterion, which relates to evaluating a general right of return, is not applicable because such a provision does not exist in the Asset Purchase Agreement. The deliverables outlined above were deemed to have stand-alone value and to meet the criteria to be accounted for as separate units of accounting. Factors considered in this determination included, among other things, BioMarin’s right under the agreement to assign the Transferred Assets, whether any other vendors sell the items separately and if BioMarin could use the delivered item for its intended purpose without the receipt of the remaining deliverables. If multiple deliverables included in an arrangement are separable into different units of accounting, the multiple-element arrangements guidance addresses how to allocate the arrangement consideration to those units of accounting. The amount of allocable arrangement consideration is limited to amounts that are fixed or determinable. Arrangement consideration is allocated at the inception of the arrangement to the identified units of accounting based on their relative selling price.

The Company identified the arrangement consideration to allocate among the units of accounting as the $2.0 million non-refundable up-front payment and the $125,675 payment to be received upon completion of the Technology Transfer. The Company excluded the potential milestone payments provided for in the Asset Purchase Agreement from the arrangement consideration as they were not considered fixed or determinable at the time the Asset Purchase Agreement was signed. Because Repligen had not sold these items on a standalone basis previously, Repligen had no vendor-specific objective evidence of selling price. Furthermore, Repligen did not have detailed third-party evidence of selling price, and as a result we used our best estimate of selling price for each item. In determining these prices, Repligen considered what Repligen would be willing to sell the items for on a standalone basis, what the market would bear for such items and what another party might charge for these items.

The up-front arrangement consideration allocated to the Transferred Assets was recognized upon execution of the Asset Purchase Agreement as the risks and rewards associated with the Transferred Assets transferred at that time. The Company used a discounted cash flow analysis to determine the value of the Transferred Assets. Key assumptions in the analysis included: the estimated market size for a compound targeted at Friedreich’s ataxia, the estimated remaining costs of development and time to commercialization, and the probability of successfully developing and commercializing the program. Based on this analysis, the Company allocated $2,115,000 to the value of the Transferred Assets. However, as the recognized revenue is limited to the non-contingent consideration received, the Company recognized $2,000,000, the amount of the up-front payment, as revenue in the three months ended March 31, 2014.

The estimated selling price of the Technology Transfer items was approximately $300,000 resulting in consideration allocation of approximately $11,000. However, as this item was not delivered prior to March 31, 2014, the Company did not recognize any revenue related to the Technology Transfer in the three months ended March 31, 2014. Repligen received the payment and recognized $125,675 of other revenues in September 2014 upon completion of the Technology Transfer.

The Company believes that a change in the key assumptions used to determine best estimate of selling price for each of the deliverables would not have a significant effect on the allocation of arrangement consideration.

In addition to the $2.1 million up-front payment, the Company is also eligible to receive up to $160 million in potential milestone payments from BioMarin comprised of:

Up to $60 million related to the achievement of specified clinical and regulatory milestone events; and

Up to $100 million related to the achievement of specified commercial sales events, specifically the first commercial sale in specific territories.

The Company evaluated the potential milestones in accordance with ASC 605-28, which allows an entity to make an accounting policy election to recognize a payment that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. This evaluation included an assessment of the risks that must be overcome to achieve the respective milestone as well as whether the achievement of the milestone was due in part to our initial clinical work, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement. There is considerable judgment involved in determining whether a milestone satisfies all of the criteria required to conclude that a milestone is substantive. Milestones that are not considered substantive are recognized as earned if there are no remaining performance obligations or over the remaining period of performance, assuming all other revenue recognition criteria are met.

The Company believes that the $60 million of specified clinical and regulatory milestone payments are substantive. Therefore, any such milestones achieved will be recognized as revenue when earned.

Any milestones achieved upon specified commercial sales events or future royalty payments are considered contingent revenue under the Asset Purchase Agreement, and will be recognized as revenue when they are earned as there are no undelivered elements remaining and no continuing performance obligations under the arrangement.

Sale of SecreFlo

On December 23, 2014, the Company sold its synthetic human secretin line, SecreFlo, to Innovate Biopharmaceuticals, Inc., or Innovate, pursuant to an asset purchase agreement. Under the terms of the agreement, Repligen received a nominal upfront payment and is eligible to receive royalties on net sales of qualified products for a period beginning on the first commercial sale of such product through the earlier of the expiration of the regulatory exclusivity period for the product or 10 years from its first commercial sale.

Pfizer License Agreement

In December 2012, the Company entered into an exclusive worldwide licensing agreement (the “License Agreement”) with Pfizer Inc. (“Pfizer”) to advance the spinal muscular atrophy program, or SMA program. Pursuant to the terms of the License Agreement, the Company received $5 million from Pfizer as an upfront payment on January 22, 2013, a $1 million milestone payment on September 4, 2013 and a $1 million milestone payment on December 28, 2014. On January 26, 2015, Pfizer notified the Company that they were terminating the License Agreement for convenience, effective as of April 26, 2015.

Therapeutics Licensing Agreements

Activities under licensing agreements are evaluated in accordance with ASC 605-25 to determine if they represent a multiple element revenue arrangement. The Company identifies the deliverables included within the agreement and evaluates which deliverables represent separate units of accounting. The Company accounts for those components as separate units of accounting if the following two criteria are met:

The delivered item or items have value to the customer on a stand-alone basis.

If there is a general right of return relative to the delivered items, delivery or performance of the undelivered items is considered probable and within our control.

Factors considered in this determination include, among other things, whether any other vendors sell the items separately and if the licensee could use the delivered item for its intended purpose without the receipt of the remaining deliverables. If multiple deliverables included in an arrangement are separable into different units of accounting, the Company allocates the arrangement consideration to those units of accounting. The amount of allocable arrangement consideration is limited to amounts that are fixed or determinable. Arrangement consideration is allocated at the inception of the arrangement to the identified units of accounting based on their relative selling price. Revenue is recognized for each unit of accounting when the appropriate revenue recognition criteria are met.

Future milestone payments, if any, under a license agreement will be recognized under the provisions of ASC 605-28, which the Company adopted on January 1, 2011. The Company has elected to recognize a payment that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. A milestone is substantive if:

It can only be achieved based in whole or in part on either (1) the Company’s performance or (2) on the occurrence of a specific outcome resulting from the Company’s performance;

There is substantive uncertainty at the date an arrangement is entered into that the event will be achieved; and

It would result in additional payments being due to the entity.

The commercial milestone payments and royalty payments received under license agreements, if any, will be recognized as revenue when they are earned.

There have been no material changes to the Company’s initial estimates related to revenue recognition in any periods presented in the accompanying consolidated financial statements.

Risks and Uncertainties

The Company evaluates its operations periodically to determine if any risks and uncertainties exist that could impact its operations in the near term. The Company does not believe that there are any significant risks which have not already been disclosed in the consolidated financial statements. A loss of certain suppliers could temporarily disrupt operations, although alternate sources of supply exist for these items. The Company has mitigated these risks by working closely with key suppliers, identifying alternate sources and developing contingency plans.

Cash, Cash Equivalents, Restricted Cash and Marketable Securities

Cash and cash equivalents include cash on hand and on deposit and highly liquid investments in money market mutual funds. All cash equivalents are carried at cost, which approximates fair value. Restricted cash represents cash that is restricted as to withdrawal or usage. In 2011, the Company issued a letter of credit in lieu of a security deposit for its leased facility in Waltham, Massachusetts, which was collateralized by a certificate of deposit held by the bank that issued the letter of credit. This certificate of deposit was classified as restricted cash in the accompanying consolidated balance sheets. As of December 31, 2016, the letter of credit was $0.5 million, the balance of restricted cash as of December 31, 2016. During 2017, the issuing bank no longer required collateral to secure the letter of credit. As a result, the Company released the funds from restricted cash.

We adopted ASU2016-18,“Statement of Cash Flows (Topic 230): Restricted Cash,”on January 1, 2018, which changed the presentation of our consolidated statements of cash flows and related disclosures for all periods presented. Accordingly, the following is a summary of our cash, cash equivalents, and restricted cash total as presented in our consolidated statements of cash flows for the years ended December 31, 2018, 2017 and 2016:

At December 31, 2016, the Company’s investments included fifteen debt securities in unrealized loss positions with a total unrealized loss of approximately $7,000 and a total fair market value of approximately $9,758,000. All investments with gross unrealized losses have been in unrealized loss positions for less than 12 months. The unrealized losses were caused primarily by current economic and market conditions. There was no change in the credit risk of the securities. The Company does not intend to sell any investments in an unrealized loss position, and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. There were no realized gains or losses on the investments for the fiscal years ended December 31, 2016, 20152018, 2017 and 2014.2016.

Fair Value Measurement

In determining the fair value of its assets and liabilities, the Company uses various valuation approaches. The Company employs a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and

are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

 

Level 1 –

 Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2 –

 Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.

Level 3 –

 Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement.

The Company’s fixed income investments are comprised of obligations of U.S. government agencies, corporate debt securities and other interest bearing securities. These investments have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. The Company validates the prices provided by third party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active. After completing its validation procedures, the Company did not adjust or override any fair value measurements provided by the pricing services asAs of December 31, 2016.

As of December 31, 2016,2018 and 2017, the Company hashad no other assets or liabilities for which fair value measurement is either required or has been elected to be applied, other than the liabilities for contingent consideration recorded in connection with the Refine and Atoll business combinations. The Company entered into a settlement agreement and remitted all remaining contingent consideration to BioFlash Partners, LLC (“BioFlash”) in the third quarter of 2016. The contingent consideration related to Refine is valued based on actual 2016 XCell ATF sales. The contingent consideration related to Atoll is valued based on achieving 2016 sales growth metrics. These valuations are Level 3 valuations, as the primary inputs are unobservable.

Changes in the fair value of contingent consideration in the year ended December 31, 2016 are primarily attributable to contingent consideration recorded at the date of the Atoll Acquisition in the amount of €836,000 (approximately $928,000), an increase to the expected 2016 Refine milestone payment of $3,048,000, an increase to the expected 2016 Atoll milestone payment of €164,000 (approximately $182,000), a $4,350,000 milestone payment to Refine, a $130,000 minimum royalty payment made to BioFlash, and a final settlement payment of $500,000 to BioFlash, of which $301,000 was previously accrued as contingent consideration and $199,000 was recorded to selling, general and administrative expenses.

The significant unobservable input used in the fair value measurement of Refine’s contingent consideration is actual 2016 revenues. The fair value of the 2016 contingent payment was increased by $3,048,000 during the year as forecasted revenues increased.

As of December 31, 2016, the fair value of Atoll’s contingent consideration is €1,000,000 (approximately $1,052,000). The significant unobservable input used in the fair value measurement was actual 2016 revenue growth compared to 2015. The initial valuation of contingent consideration upon the Atoll Acquisition in April 2016 resulted in a fair value of €836,000 (approximately $928,000). The estimated fair value of the contingent payment was increased by €164,000 (approximately $182,000) based on Atoll achieving the targeted revenue growth in 2016.applied.

In May 2016, the Company issued $115$115.0 million aggregate principal amount of the Notes due June 1, 2021. Interest is payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2016. As of December 31, 2016,2018, the carrying value of the Notes was $95.3$103.5 million, net of unamortized discount, and the fair value of the Notes was approximately $135.6$184.6 million. The fair value of the Notes is a Level 1 valuation and was determined based on the most recent trade activity of the Notes as of December 31, 2016.2018. The Notes are discussed in more detail in Note 10, “Convertible“Convertible Senior Notes.Notes”to these consolidated financial statements

There were no remeasurements to fair value during the year ended December 31, 20162018 of financial assets and liabilities that are not measured at fair value on a recurring basis.

Inventories

Inventories relate to the Company’s bioprocessing business. The Company values inventory at cost or, if lower, fair marketnet realizable value, using thefirst-in,first-out method. The Company reviews its inventories at least quarterly and records a provision for excess and obsolete inventory based on its estimates of expected sales volume, production capacity and expiration dates of raw materials,work-in-process and finished products. Expected sales volumes are determined based on supply forecasts provided by key customers for the next 3 to 12 months. The

Company writes down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements to cost of product revenue. Manufacturing of bioprocessing finished goods is done to order and tested for quality specifications prior to shipment. Reserves for excess and obsolete inventory were $435,000 and $343,000 as of December 31, 2016 and 2015, respectively. The reserve balance at December 31, 2016 and 2015 is sufficient to cover excess or obsolete inventory for the consolidated Company.

A change in the estimated timing or amount of demand for the Company’s products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on the value of inventory and reported operating results. During all periods presented in the accompanying financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

Work-in-process and finished products inventories consist of material, labor, outside processing costs and manufacturing overhead.

Inventories consistLease Accounting

Certain of the following (in thousands):Company’s operating leases where the Company is the lessee provide for minimum annual payments that increase over the life of the lease. The aggregate minimum annual payments are expensed on the straight-lined basis beginning when the Company takes possession of the property and extending over the term of the related lease, including renewal options when the exercise of the option is reasonably assured as an economic penalty may be incurred if the option is not exercised. The amount by which straight-line rent exceeds actual lease payment requirements in the early years of the leases is accrued as deferred rent and reduced in later years when the actual cash payment requirements exceed the straight-line expense. The Company also accounts in its straight-line computation for the effect of any “rental holidays” and lessor-paid tenant improvements.

Accrued Liabilities

The Company estimates accrued liabilities by identifying services performed on the Company’s behalf, estimating the level of service performed and determining the associated cost incurred for such service as of each balance sheet date. For example, the Company would accrue for professional and consulting fees incurred with law firms, audit and accounting service providers and other third partythird-party consultants. These expenses are determined by either requesting those service providers to estimate unbilled services at each reporting date for services incurred or tracking costs incurred by service providers under fixed fee arrangements.

The Company has processes in place to estimate the appropriate amounts to record for accrued liabilities, which principally involve the applicable personnel reviewing the services provided. In the event that the Company does not identify certain costs that have begun to be incurred or the Company under or over-estimates the level of services performed or the costs of such services, the reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services often require the exercise of judgment. The Company makes these judgments based upon the facts and circumstances known at the date of the financial statements.

Income Taxes

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided, if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions using a “more-likely-than-not”“more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of

tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. The Company evaluates this tax position on a quarterly basis. The Company also accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.

Earnings Per Share

Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents then outstanding. Potential common share equivalents consist of restricted stock awards and the incremental common shares issuable upon the exercise of stock options and warrants. Under the treasury stock method, unexercised “in-the-money”“in-the-money” stock options are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. Share-based payment awards that entitle their holders to receivenon-forfeitable dividends before vesting are considered participating securities and are included in the calculation of basic and diluted earnings per share. There are no such participating securities as of December 31, 2018.

At December 31, 2016,2018, there were outstanding options to purchase 1,236,586998,226 shares of the Company’s common stock at a weighted average exercise price of $12.05$27.54 per share.share and 705,413 shares of common stock issuable upon the vesting of restricted stock units (“RSUs”). For the fiscal year ended December 31, 2016, 381,6862018, 479,854 shares of the

Company’s common stock were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore, anti-dilutive.

As provided by the terms of the indenture underlying the senior convertible notes, the Company has a choice to settle the conversion obligation for the Convertible Notes in cash, shares or any combination of the two. The Company currently intends to settle the par value of the Convertible Notes in cash and any excess conversion premium in shares. The Company applies the provisions of ASC 260,Earnings Per Share,Share”, Subsection10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on its convertible notes. Accordingly, the par value of the Convertible Notes willis not be included in the calculation of diluted income per share, but the dilutive effect of the conversion premium will beis considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the Company’s convertible notesConvertible Notes is based on the difference between the Company’s current period average stock price and the conversion price of the convertible notes, provided there is a premium. Pursuant to this accounting standard, there is no dilution from the accreted principal of the Convertible Notes.

Concentrations of Credit Risk and Significant Customers

Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash and cash equivalents, marketable securities and accounts receivable. Per the Company’s investment policy, cash equivalents and marketable securities are invested in financial instruments with high credit ratings and credit exposure to any one issue, issuer (with the exception of U.S. treasury obligations) and type of instrument is limited. At December 31, 20162018 and 2015,2017, the Company had no investments associated with foreign exchange contracts, options contracts or other foreign hedging arrangements.

Concentration of credit risk with respect to accounts receivable is limited to customers to whom the Company makes significant sales. While a reserve for the potentialwrite-off of accounts receivable is maintained, the

Company has not written off any significant accounts to date. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition.

Revenue from significant customers as a percentage of the Company’s total revenue is as follows:

Goodwill, Other Intangible Assets and Acquisitions

Acquisitions

Total consideration transferred for acquisitions is allocated to the assets acquired and liabilities assumed, if any, based on their fair values at the dates of acquisition. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions determined by management. Any excess of purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Any excess of the fair value of the net tangible and intangible assets acquired over the purchase price is recognized in the statement of operations.operations and comprehensive income. The fair value of contingent consideration includes estimates and judgments made by management regarding the probability that future contingent payments will be made and the extent of royalties to be earned in excess of the defined minimum royalties. Management updates these estimates and the related fair value of contingent consideration at each reporting period. Changes in the fair value of contingent consideration are recorded in the consolidated statements of operations.operations and comprehensive income.

The Company uses the income approach to determine the fair value of certain identifiable intangible assets including customer relationships and developed technology. This approach determines fair value by estimatingafter-tax cash flows attributable to these assets over their respective useful lives and then discounting theseafter-tax cash flows back to a present value. The Company bases its assumptions on estimates of future cash flows, expected growth rates, expected trends in technology, etc. Discount rates used to arrive at a present value as of the date of acquisition are based on the time value of money and certain industry-specific risk factors.

Goodwill

Goodwill is not amortized and is reviewed for impairment at least annually.annually at the reporting unit level. There was no evidence of impairment to goodwill at December 31, 2016.2018 and 2017. There were no goodwill impairment charges during the fiscal years ended December 31, 2016, 20152018, 2017 and 2014.2016.

Intangible Assets

Intangible assets are amortized over their useful lives using the estimated economic benefit method, as applicable, and the amortization expense is recorded within cost of product revenue and selling, general and administrative expense in the statements of operations.operations and comprehensive income. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions exist that would indicate

the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for our products or changes in the size of the market for our products. If impairment indicators are present, the Company determines whether the underlying intangible asset is recoverable through estimated future undiscounted cash flows. If the asset is not found to be recoverable, it is written down to the estimated fair value of the asset based on the sum of the future discounted cash flows expected to result from the use and disposition of the asset. If the estimate of an intangible asset’s remaining useful life is changed, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. The Company continues to believe that its intangible assets are recoverable at December 31, 2016.2018.

Stock Based Compensation

The Company measures stock-based compensation cost at the grant date based on the estimated fair value of the award and recognizes it as expense over the employee’s requisite service period on a straight-line basis. The Company records the expense for share-based awards subject to performance-based milestone vesting over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates whether the achievement of a performance-based milestone is probable as of the reporting date. The Company has no awards that are subject to market conditions. The Company recognizes stock-based compensation expense based upon options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted by an amount of estimated forfeitures.

The Company uses the Black-Scholes option pricing model to calculate the fair value of share-based awards on the grant date. The following assumptions are used in calculating the fair value of share-based awards:

Expected term – The expected term of options granted represents the period of time for which the options are expected to be outstanding. For purposes of estimating the expected term, the Company has aggregated all individual option awards into one group as the Company does not expect substantial differences in exercise behavior among its employees.

Expected volatility – The expected volatility is a measure of the amount by which the Company’s stock price is expected to fluctuate during the expected term of options granted. The Company determines the expected volatility based primarily upon the historical volatility of the Company’s common stock over a period commensurate with the option’s expected term.

Risk-free interest rate – The risk-free interest rate is the implied yield available on U.S. Treasuryzero-coupon issues with a remaining term equal to the option’s expected term on the grant date.

Expected dividend yield – The Company has never declared or paid any cash dividends on any of its capital stock and does not expect to do so in the foreseeable future. Accordingly, the Company uses an expected dividend yield of zero to calculate the grant-date fair value of a stock option.

Estimated forfeiture rates – The Company has applied, based on an analysis of its historical forfeitures, annual forfeiture rates of 8% for awards granted tonon-executive level employees, 3% for awards granted to executive level employees and 0% for awards granted tonon-employee members of the Board of Directors to all unvested stock options as of December 31, 2014.2018. The Company reevaluates this analysis periodically and adjusts these estimated forfeiture rates as necessary. Ultimately, the Company will only recognize expense for those shares that vest.

Advertising Costs

The Company expenses advertising costs as they are incurred. Advertising expense for the years ended December 31, 2018, 2017 and 2016 was $0.2 million, $0.2 million and $0.4 million, respectively.

Recent Accounting Standards Updates

We consider the applicability and impact of all Accounting Standards Updates on our condensed consolidated financial statements. Updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. Recently issued Accounting Standards Updates which we feel may be applicable to us are as follows:

Recently Issued Accounting PronouncementsStandard Updates – Not Yet Adopted

In April 2014,February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) No. 2015-03, “Interest2016-02, “Leases (Topic 842).”ASU2016-02, along with subsequent ASUs issued to clarify certain provisions of ASU2016-02 (collectively known as “ASC 842”), establishes aright-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the consolidated balance sheet for all leases with terms longer than 12 months. Certain qualitative and quantitative disclosures are also required. The Company will adopt ASU2016-02 and related amendments on January 1, 2019 using an optional method allowed with the issuance of ASU2018-11,“LeasesImputationTargeted Improvements (Topic 842),” in July 2018. ASU2018-11 gives entities the option to not provide comparative period financial statements and instead apply the transition requirements as of Interest (Topic 835): Simplifying the Presentationeffective date of Debt Issuance Costs.” ASU 2015-03 requires that debt issuancethe new standard. Pursuant to additional guidance under ASC 842, the Company will also elect the optional package of practical expedients, which will allow the Company to not reassess: (i) whether expired or existing contracts contain leases; (ii) lease classification for any expired or existing leases; and (iii) initial direct costs relatedfor any existing leases. ASC 842 also allow entities to make certain policy elections, some of which the Company plans to elect, including a recognized debt liability be presented inpolicy to not record short-term leases on the balance sheet as mentioned above. The Company is currently working through the implementation of transition-related controls and finalizing accounting elections. Although the Company is still assessing the potential impact this standard will have on its consolidated financial statements and disclosures, the Company currently estimates total ROU assets to be within the range of approximately $12 million to $14 million and lease liabilities to be within the range of approximately $16 million to $18 million upon adoption, before considering deferred taxes. The difference between the two ranges is due to approximately $4 million of unamortized lease incentives and deferred rent at the Company’s Marlborough and Waltham facilities as of December 31, 2018. The Company does not expect the adoption of ASC 842 to have a direct deductionmaterial impact on the consolidated statements of operations or consolidated statements of cash flows.

In February 2018, the FASB issued ASU2018-02,“Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which gives entities the carrying amountoption to reclassify to retained earnings tax effects related to items that have been stranded in accumulated other comprehensive income as a result of that debt liability. The ASU becamethe Tax Cuts and Jobs Act (the “Act”). For all entities, the guidance is effective for public entities for fiscal years beginning after December 15, 2015.2018, and interim periods within those fiscal years. Entities can choose whether to apply the amendments retrospectively to each period in which the effect of the Act is recognized or to apply the amendments in the period of adoption. The Company appliedwill adopt this guidance on January 1, 2019 and does not expect its adoption to have a material impact on the amended presentationits consolidated financial statements.

In August 2018, the FASB issued ASU2018-13,“Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.”ASU2018-13 includes amendments that aim to improve the effectiveness of fair value measurement disclosures. The amendments in this guidance modify the disclosure requirements on fair value measurements based on the concepts in conjunction with its issuanceFASB Concepts Statement,“Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements, including the consideration of convertible senior notescosts and benefits. The amendments become effective for the Company in the second quarteryear ending December 31, 2020 and early adoption is permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.

In August 2018, the FASB issued ASU2018-15,“Intangibles – Goodwill and Other –Internal-Use Software (Subtopic350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing

Arrangement That Is a Service Contract.”ASU2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtaininternal-use software (and hosting arrangements that include aninternal-use software license). The guidance also requires the entity to expense the capitalized implementation costs of 2016.a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. The guidance becomes effective for the Company in the year ending December 31, 2020 and early adoption is permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.

In November 2018, the FASB issued ASU2018-18,“Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606.”ASU2018-18 clarifies the interaction between Topic 808,“Collaborative Arrangements,”and Topic 606,“Revenue from Contracts with Customers,”by making targeted improvements to US GAAP for collaborative arrangements and providing guidance on whether certain transactions between collaborative arrangement participants should be accounted for with revenue under Topic 606. This includes improving comparability in the presentation of revenue for certain transactions between collaborative arrangement participants by allowing presentation of the units of account in collaborative arrangements that are within the scope of Topic 606 together with revenue accounted for under Topic 606. The guidance becomes effective for the Company in the year ending December 31, 2020 and early adoption is permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.

Recently Issued Accounting Standard Updates – Adopted During the Period

In May 2014, the FASB issuedASU No. 2014-09, “Revenue“Revenue from Contracts with Customers (Topic 606),” (“ASC 606”) which supersedes the revenue recognition requirements in Accounting Standards Codification TopicASC 605,Revenue Recognition, and creates a new Topic 606,Revenue from Contracts with Customers. Two adoption methods are permitted: retrospectively to all prior reporting periods presented, with certain practical expedients permitted; or retrospectively with the cumulative effect of initially adopting the ASU recognized at the date of initial application. The adoption of this ASU will includeincluded updates as provided under ASU2015-14, “Revenue“Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”; ASU2016-08, “Revenue“Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”; ASU2016-10, “Revenue“Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing”; and ASU2016-12, “Revenue“Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” The Company intends to adoptadopted the provisions of TopicASC 606 using the modified retrospective method effective January 1, 2018, and it has formed a project team to assess and implement2018. See Note 4,“Revenue Recognition”,below for further discussion of the effects of this new standard. The Company has not made a determinationstandard on the impact to itsCompany’s consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory” (“ASU 2015-11”). ASU 2015-11 requires inventory be measured at the lower of cost and net realizable value, and options that currently exist for market value be eliminated. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is effective prospectively for reporting periods beginning after December 15, 2016 and interim periods within those fiscal years with early adoption permitted. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its consolidated financial statements, as it currently does not measure any inventory at market value.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize a right-of-use asset and a lease liability for most leases. Extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing contracts. The accounting applied by a lessor is largely unchanged from that applied under the current standard. The standard must be adopted using a modified retrospective transition approach and provides for certain practical expedients. The ASU is effective for public entities for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company has not yet completed its assessment of the impact of the new standard on its consolidated financial statements; however, the Company anticipates that it will recognize right-of-use assets and lease liabilities for leases on its current facilities.

In March 2016, the FASB issued ASU No. 2016-09, “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”, which aims to simplify several aspects of the

accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, classification of certain items on the statement of cash flows and accounting for forfeitures. The ASU is effective for public entities for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company intends to adopt the provisions of this ASU as of January 1, 2017; the Company does not expect the impact of this new standard to have a material effect on its 2017 consolidated financial statements, as the Company will not be required to change its accounting treatment of forfeitures, classification of current awards or cash flow disclosures.

In August 2016, the FASB issued ASU No. 2016-15, “Statement“Statement of Cash Flows (Topic 203): Classification of Certain Cash Receipts and Cash Payments”.Payments.” ASU No. 2016-15 addresses eight specific cash flow issues and clarifies their presentation and classification in the Statement of Cash Flows. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively with early adoption permitted. The Company currently classifieshas historically classified payments up to the amount of its contingent consideration liability recognized at the date of its acquisitionsacquisition as financing activities, with additional payments classified as operating activities. As a result,Because the Company does not expecthas classified its contingent consideration payments as required by this standard, the adoption of this standard did not have any impact on its consolidated financial statements when applied on a retrospective basis.

In October 2016, the FASB issued ASU2016-16, “Intra-Entity Transfers of Assets Other Than Inventory.” ASU2016-16 requires that the income tax consequences of an intra-entity asset transfer other than inventory are recognized at the time of the transfer. An entity will continue to recognize the income tax consequences of an intercompany transfer of inventory when the inventory is sold to a third party. The Company adopted this standard on a modified-retrospective basis on January 1, 2018. See Note 7,“Income Taxes”,below for a discussion of the impact of this ASU 2016-15on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU2016-18,“Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that the statement of cash flows explain the change during the period in the total cash, which is inclusive of cash and cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances on the statement of cash flows upon adoption of this standard. The Company adopted this standard on a retrospective basis on January 1, 2018. The adoption resulted in an increase to cash, cash equivalents and restricted cash of $450,000 in the statement of cash flows at December 31, 2016 and September 30, 2017. The Company did not hold any restricted cash at December 31, 2018 or December 31, 2017.

In January 2017, the FASB issuedASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”, which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this standard as of January 1, 2018, and the adoption of ASU2017-01 did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU2017-04,“Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” eliminating the requirement to calculate the implied fair value, essentially eliminating step two from the goodwill impairment test. ASU2017-04 requires goodwill impairment to be based upon the results of step one of the impairment test, which is defined as the excess of the carrying value of a reporting unit over its fair value. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard is effective for the Company on a prospective basis beginning on January 1, 2020, with early adoption permitted. The Company adopted this standard as of January 1, 2018, and the adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

These bioprocessing products account for the Atoll Acquisition, the Company issued and contributed 538,700 sharesmajority of the Company’s common stock, par valueSpectrum revenues. Spectrum also offers a line of $0.01 per share valued at $14.1 million (the “Stock Consideration”) to Repligen Sweden through a transfer by the Company on behalf of Repligen Sweden to fulfill Repligen Sweden’s obligation to deliver the Stock Consideration under the Share Purchase Agreement. The issuance of the Stock Consideration was not registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon the exemption from registration provided by Section 4(2) of the Securities Act. The Stock Consideration was based on the fair value of the Company’s common stock on April 1, 2016.

This acquisition strengthened Repligen’s bioprocessing business by adding a complementary extension to an existing product line while expanding its direct sales presence worldwide. On September 20, 2016, Atoll changed its name to Repligen GmbH.

The Atoll Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations.” The total purchase price of the Atoll Acquisition was $25.3 million, consisting of an upfront cash payment of $10.2 million, less $74,000 as a result of the final determination of working capital, issuance of the Stock Consideration, and a future potential milestone payment of $1.1 million if specific revenue growth targets are met for 2016. The $1.1 million potential contingent consideration had an initial probability weighted fair value at the time of the closing of the Atoll Acquisition of approximately $952,000.operating room products.

Consideration Transferred

The Company accounted for the AtollSpectrum Acquisition as thea purchase of a business under U.S. GAAP.ASC 805,“Business Combinations.” The Spectrum Acquisition was funded through payment of $122.9 million in cash, the issuance of 6,153,995 unregistered shares of the Company’s common stock totaling $247.6 million and a working capital adjustment of $0.4 million for a total purchase price of $370.9 million. Under the acquisition method of accounting, the assets of AtollSpectrum were recorded as of the acquisition date, at their respective

fair values, and consolidated with those of Repligen.the Company. The fair value of the net assets acquired was approximately $25.3$370.9 million.

The preparation of theconsideration and purchase price information has been prepared using a valuation that required the use of significant assumptions and estimates.estimates in its preparation. Critical estimates included, but were not limited to, future expected cash flows, including projected revenues and expenses, and the applicable discount rates. These estimates were based on assumptions that the Company believes to be reasonable. However,reasonable; however, actual results may differ from these estimates.

The fair value of contingent consideration was determined based upon a probability weighted analysis of expected future milestone and settlement payments to be made to the Seller. The Company could make a contingent consideration payment of $1.1 million if specific revenue growth targets are met for 2016. The liability for contingent consideration is included in current liabilities on the consolidated balance sheets. Because the contingent consideration relates only to 2016 sales growth, no further remeasurement of this liability is required as of December 31, 2016. See Note 9—Accrued Liabilities for further details.

TangenX Technology Corporation

On December 14, 2016, the Company acquired TangenX Technology Corporation (“TangenX”), pursuant to the terms of the Share Purchase Agreement, dated as of December 14, 2016 (the “Share Purchase Agreement”), by and among the Company and TangenX (such acquisition, the “TangenX Acquisition”). The Company acquired all outstanding shares and the business of TangenX, including TangenX’s innovative single-use Sius line of tangential flow filtration (“TFF”) cassettes and hardware used in downstream biopharmaceutical manufacturing processes.

Sius TFF is used in the filtration of biological drugs, complimenting Repligen’s OPUS line of pre-packed chromatography columns used in downstream purification. Pursuant to the Share Purchase Agreement, Repligen acquired all of the outstanding shares of TangenX, as well as certain assets and liabilities.

The TangenX Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations.” The total purchase price of the TangenX Acquisition was $37.1 million in cash.

Consideration Transferred

The Company accounted for the TangenX Acquisition as the purchase of a business under U.S. GAAP. Under the acquisition method of accounting, the assets of TangenX were recorded as of the acquisition date, at their respective fair values, and consolidated with those of Repligen. The fair value of the net assets acquired was approximately $37.1 million.

The preparation of the valuation required the use of significant assumptions and estimates. Critical estimates included, but were not limited to, future expected cash flows, including projected revenues and expenses, and the applicable discount rates. These estimates were based on assumptions that the Company believes to be reasonable. However, actual results may differ from these estimates.

Filtration Products

The Company’s Filtration product line generates revenue through the sale of KrosFlo® hollow fiber (“HF”) TFF membranes and modules, ProConnex®single-use flow path connectors, flat sheet TFF cassettes and hardware, and XCell alternating tangential flow (“ATF”) devices and related consumables.

The Company markets the KrosFlo line of HF cartridges and TFF systems and the ProConnex line ofsingle-use flow path connectors which were acquired as part of the Spectrum Acquisition. These products are used in the Republicfiltration, isolation, purification and concentration of Singapore),biologics and diagnostic products. Sales of large-scale systems generally include components and consumables as well as training and installation services at the request of the customer. Because the initial sale of components and consumables are necessary for the operation of the system, such items are combined with the systems as a single performance obligation. Training and installation services do not significantly modify or customize these systems and therefore represent a distinct performance obligation.

The Company’s other Filtration product offerings are not highly interdependent of one another and are therefore considered distinct products that represent separate performance obligations. Revenue on these products is generally recognized at a point in time upon transfer of control to the customer. The Company acquiredinvoices the businesscustomer for the installation and training services in an amount that directly corresponds with the value to the customer of Refine, including Refine’s Alternating Tangential Flow (“ATF”)the Company’s performance to date; therefore, revenue recognized is based on the amount billable to the customer in accordance with the practical expedient under ASC606-10-55-18.

The Company also markets flat sheet TFF cassettes and hardware. TFF is a rapid and efficient method for separation and purification of biomolecules that is widely used in laboratory, process development and process scale applications in biopharmaceutical manufacturing. The Company’ssingle-use SIUS TFF cassettes and hardware are not highly interdependent of one another and are therefore considered distinct products that represent separate performance obligations. SIUS TFF product revenue is generally recognized at a point in time upon transfer of control to the customer.

The Company also markets the XCell ATF System, a market-leadingtechnologically advanced filtration device used in upstream processes to significantly increase product yieldcontinuously remove cellular metabolic waste products during the course of a fermentation step ofrun, freeing healthy cells to continue producing the biologic drug manufacturing process (the “Refine Business”of interest. ATF Systems typically include a filtration system and consumables (i.e., tube devices, metal stands) as well as training and installation services at the acquisitionrequest of the Refine Business, the “Refine Acquisition”). Pursuant to the Asset Purchase Agreement, Repligen purchased allcustomer. The filtration system and consumables are considered distinct products and therefore represent separate performance obligations. First time purchasers of the assets related to Refine’s ATFsystems typically purchase a controller that is shipped with the tube device(s) and metal stand(s). The controller is not considered distinct as it is a proprietary product that is highly interdependent with the filtration system; therefore, the controller is combined with the filtration system and assumed certain specified liabilities related to Refine’s ATF system. This acquisition strengthened Repligen’s bioprocessing business by adding a complementary product line while expanding its direct sales presence worldwide. The transaction was accounted for as a purchasesingle performance obligation. The training and installation services do not significantly modify or customize the ATF system and therefore represent a distinct performance obligation. ATF system product revenue related to the filtration system (including the controller if applicable) and consumables is generally recognized at a point in time upon transfer of a business under ASC 805, Business Combinations.control to the customer. ATF system service revenue related to training and installation services is generally recognized over time, as the customer simultaneously receives and consumes the benefits as the Company performs. The terms ofCompany invoices the acquisition includedcustomer for the installation and training services in an upfront cash payment of approximately $21,236,000 less approximately $66,000 as a result ofamount that directly corresponds with the final determination of working capital, issuance of 215,285 sharesvalue to the customer of the Company’s $0.01 par value common stock valued at $4,000,000, future potential milestone payments totaling upperformance to $10,900,000 if specific sales targets are met fordate; therefore, revenue recognized is based on the years 2014, 2015 and 2016, and future potential payments upamount billable to $7,500,000 out of any amounts that might be receivedthe customer in connectionaccordance with the resolution, withdrawalpractical expedient under ASC606-10-55-18.

Chromatography Products

The Company’s Chromatography product line includes a number of products used in the downstream purification and quality control of biological drugs. The majority of chromatography revenue relates to the OPUSpre-packed chromatography column line and Protein A chromatography resins. OPUS columns typically consist of the outer hardware of the column with a resin as ordered by the customer packed inside of the column. OPUS columns may also be ordered without the packed resin. In either scenario, the OPUS column and resin are not interdependent of one another and are therefore considered distinct products that represent separate performance obligations. Chromatography product revenue is generally recognized at a point in time upon transfer of control to the customer.

Protein Products

The Company’s Protein product line generates revenue through the sale of Protein A ligands and growth factors. Protein A ligands are an essential component of Protein A chromatography resins (media) used in the purification

of virtually all monoclonal antibody (“mAb”)-based drugs on the market or settlementin development. The Company manufactures multiple forms of Protein A ligands under long-term supply agreements with major life sciences companies, who in turn sell their Protein A chromatography media to end users (biopharmaceutical manufacturers). The Company also manufactures growth factors for sale under long-term supply agreements with certain life sciences companies as well as direct sales to its customers. Each protein product is considered distinct and therefore represents a separate performance obligation. Protein product revenue is generally recognized at a point in time upon transfer of control to the customer.

Other Products

The Company’s other products include operating room products sold to hospitals. Other product revenue is generally recognized at a point in time upon transfer of control to the customer.

Transaction Price Allocated to Future Performance Obligations

Remaining performance obligations represents the transaction price of contracts for which work has not been performed or has been partially performed. The Company’s future performance obligations relate primarily to the installation and training of certain patent disputesof its systems sold to customers. These performance obligations are completed within one year of receipt of a purchase order from its customers. Accordingly, the Company has elected to not disclose the value of these unsatisfied performance obligations as provided under ASC606-10-50-14.

A contract asset is created when the Company satisfies a third party. The $10,900,000 potential contingent consideration had an initial probability weighted fair value at acquisition of $1,370,000. The $7,500,000 potential contingent consideration had onlyperformance obligation by transferring a nominal probability weighted fair value at acquisition. In additionpromised good to the initialcustomer. Contract assets may represent conditional or unconditional rights to consideration. The right is conditional, and recorded as a contract asset, if the Company must first satisfy another performance obligation in the contract before it is entitled to payment from the customer. Contract assets are transferred to billed receivables once the right becomes unconditional. If the Company has the unconditional right to receive consideration approximately $774,000 was paidfrom the customer, the contract asset is accounted for as a billed receivable and presented separately from other contract assets. A right is unconditional if nothing other than the passage of time is required before payment of that consideration is due.

When consideration is received, or such consideration is unconditionally due, from a customer prior to Refine following the acquisition under a Transition Services Agreement under which certain employees of Refine providedtransferring goods or services to the Company in supportcustomer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the Refine Business. As these payments were contingent upon future service, they were recognized as operating expense, ratably whileproducts or services is transferred to the services were provided.customer and all revenue recognition criteria have been met.

Consideration TransferredCosts to Obtain or Fulfill a Customer Contract

The Company’s sales commission structure is based on achieving revenue targets. The commissions are driven by revenue derived from customer purchase orders which are short term in nature.

Applying the practical expedient in paragraph340-40-25-4, the Company accounted forrecognizes the Refine Acquisitionincremental costs of obtaining contracts as an expense when incurred if the purchaseamortization period of a business under U.S. GAAP. Under the acquisition method of accounting, the assets of the Refine Business were recorded as of the acquisition date, at their respective fair values, and consolidated with those of Repligen. The fair value of the net assets acquired was approximately $26,540,000.

The preparation of the valuation required the use of significant assumptions and estimates. Critical estimates included, but were not limited to, future expected cash flows, including projected revenues and expenses, and the applicable discount rates. These estimates were based on assumptions that the Company believes to be reasonable. However, actual results may differ from these estimates.

The fair value of contingent consideration was determined based upon a probability weighted analysis of expected future milestone and settlement payments to be made to the seller. The Company paid $4,350,000 to Refine in 2016 for achievements of sales targets met in 2015 and $1,000,000 to Refine in 2015 for achievements of sales targets met in 2014, and could make payments of up to $9,900,000 if specific sales targets are met in 2015 and 2016. In addition, the Company could pay Refine up to $7,500,000 out of any receipts that might be received in connection with the resolution, withdrawalotherwise would have recognized is one year or settlement of certain patent disputes with a third party. The liability for contingent consideration is included in current and long-term liabilities on the consolidated balance sheets and will be remeasured at each reporting period until the contingency is resolved. Please see Note 9 – Accrued Liabilities for further details.

Acquisition related costs are not included as a component of consideration transferred, but are expensed in the periods in which the costs are incurred.

Those assets are considered indefinite lived until efforts associatedamortized, but instead is tested for impairment at least annually in accordance with the projects are completed or abandoned. The major acquired technology IPR&D relates to the development of a single use system product extension to the XCell ATF System business. The Company launched its XCell ATF single-use product line in the third quarter of 2016. The Company performed an assessment of the in-process research and development assets and their estimated useful lives to determine if any circumstances exist that would result in an impairment. The Company has determined that the fair value of these intangible assets exceeds their carrying values and are therefore not impaired; accordingly, the Company reclassified in-process research and development intangible assets to developed technology and began to amortize these intangible assets in the third quarter of 2016.

The excess of the purchase price over the fair value of tangible and intangible assets acquired was recorded to goodwill. The goodwill recognized is attributable to expected synergies that the Company will realize from this acquisition. This goodwill is deductible for tax purposes over the next 15 years.

Revenue, Net Income and Pro Forma Presentation

The Company recorded revenue from Refine of $6,793,000 from June 2, 2014 through December 31, 2014. The segregation of Refine’s net income is administratively impractical, as the Company operates as one operating segment and does not separately allocate expenses.

Other Intangible Assets

Intangible assets, except for the ATF tradename, are amortized over their useful lives using the estimated economic benefit method, as applicable, and the amortization expense is recorded within selling, general and administrative expense in the Company’s statements of operations and comprehensive income. The ATF tradename areis not amortized. The Company reviews its indefinite-lived intangible assets not subject to amortization to determine if adverse conditions exist or a change in circumstances exists that would indicate an impairment. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions exist that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for our products or changes in the size of the market for our products. An impairment results if the carrying value of the asset exceeds the estimated fair value of the asset. If the estimate of an intangible asset’s remaining useful life is changed, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. The Company continues to believe that its intangible assets are recoverable at December 31, 2016.2018.

The net change in the total valuation allowance for the year ended December 31, 2018 was an increase of $0.1 million. The net change in the total valuation allowance for the year ended December 31, 2017 was a decrease of $8,535,000$10.0 million which included the changes below. During the first quarter of 2017 the Company adopted ASU2016-09. ASU2016-09 states that previously unrecognized excess

tax benefits related to stock-based compensation should be recognized on a modified retrospective basis. As such, the Company increased its U.S. federal and state net operating loss carryovers by $5.1 million as of January 1, 2017 for previously unrecognized stock-based compensation excess tax benefits outstanding as of the beginning of the period. Because the Company maintained a full valuation allowance on its U.S. deferred tax assets at that date, the Company recorded a corresponding increase to the valuation allowance as of January 1, 2017. During the second quarter of 2017, the Company agreed to sell certain intellectual property to Repligen Sweden AB that allowed for the Company to utilize certain of its U.S. deferred tax assets. Accordingly, the Company reduced its valuation allowance on its U.S. deferred tax assets by $9.2 million. Additionally, in conjunction with the Spectrum Acquisition, the Company determined that its U.S. deferred tax assets were more likely than not to be realized after considering deferred tax liabilities related to the acquired intangible assets. Accordingly, the Company reduced its valuation allowance on its U.S. deferred tax assets by $5.9 million. The valuation allowance decreased by $8.5 million for the year ended December 31, 2016. U.S. jurisdiction deferred tax assets, previously subject to a valuation allowance, were initially recognized in 2016 due to the creation of a $4,525,000 deferred tax liability resulting from the TangenX Acquisition and a $6,514,000 deferred tax liability resulting from the issuance of the Company’s convertible senior notes, partially offset by increases in deferred tax assets derived from temporary timing differences. The $6,514,000 decrease to the valuation allowance was recorded to stockholder’s equity. The cumulative U.S. federal net operating loss includes $14,177,000 related to excess tax deductions from share-based payments, the tax benefit of which will be recognized as an increase to additional paid in capital when the deduction reduces current taxes payable. The valuation allowance increased by $1,216,000 for the year ended December 31, 2015 and increased by $727,000 for the year ended December 31, 2014. As of December 31, 2016,2018, the Company continues to believebelieves that realization of the remainder of its deferred tax assets beyond December 31, 2016 isrelated to capital loss carryovers and certain foreign tax credits are not more likely than not, and the Company continues to maintain its valuation allowance against its remainingthose U.S. deferred tax assets with the exception for certain state tax credits.assets.

In December 2015, the Company reached a negotiated settlement with the DOR regarding an appeal of an assessment made in 2013 for the years ended March 31, 2008 and 2009. The primary issues in the appeal related to the sourcing of intellectual property settlements and the qualification of Research and Development tax credits. The final settlement resulted in a payment to the DOR of approximately $1,012,000, inclusive of interest. Of this amount, $926,000 had been provided for as a liability for an uncertain tax position as of September 30, 2015.

The Company’s tax returns are subject to examination by federal, state and international taxing authorities for the following periods:

At December 31, 2016, the Company had accumulated Federal research credits of $2,814,000 which were not recognized for financial statement purposes, as it was not more likely than not that the Company would have sufficient earnings to realize those benefits in addition to the benefits the Company may derive from use of its Net Operating Losses. However, given the past uncertainty at the state level regarding their sustainability under audit, the Company applied a reserve of $1,407,000 against these cumulative Federal research credits.

As of December 31, 2016,2018, the Company recognized interesthas accumulated undistributed earnings generated by our foreign subsidiaries of approximately $72.4 million. Because $58.0 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the 2017 Tax Act, any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of our foreign investments would generally be limited to foreign and penalties of $16,000.

ASU2016-16,“Intra-Entity Transfers of Assets Other Than Inventory,” requires the income tax consequences of intra-entity transfers of assets other than inventory to be recognized when the intra-entity transfer occurs rather than deferring recognition of income tax consequences until the transfer was made with an outside party. The Company adopted the provisions of this ASU in the first quarter of 2018. The adoption resulted in a decrease of $5.7 million to other assets, a decrease of $5.0 million to deferred tax assets and a decrease of $0.7 million to accumulated deficit at January 1, 2018.

The Act included aone-time deemed repatriation transition tax whereby entities that are shareholders of a specified foreign corporation must include in gross income the undistributed and previously untaxed post-1986 earnings outsideand profits of the U.S. Itspecified foreign corporation. Our provisional amount recorded at December 31, 2017 increased our tax provision by $3.3 million. As of December 31, 2018, the accounting for this item is not practicalcomplete. For the three months ended December 31, 2018, the Company recorded a tax benefit of $1.3 million, as a result of refining our calculations of post-1986 earnings and profits for our foreign subsidiaries.

As part of the April 2016 transition agreement, all outstanding equity awards continued to vest through December 31, 2016, and fifty percent (50%) of the option awards that are unvested on February 28, 2017 immediately vested and became exercisable as of that date. As a result of these modifications to his share-based payment arrangements, the Company incurred stock compensation expense of $292,000$0.3 million for the year ended December 31, 2016. This expense was recorded to research and development expense on the Company’s consolidated statement of operations.

As part of the January 2015 transition agreement, all outstanding equity awards continued to vest through December 31, 2015, and fifty percent (50%) of the option awards that are unvested on December 31, 2015 immediately vested and became exercisable as of that date. As a result of these modifications to his share-based payment arrangements, the Company incurred stock compensation expense of $826,000 for the year ended December 31, 2015. This expense was recorded to selling, general and administrative expense on the Company’s consolidated statement of operations.comprehensive income.

The 20122018 Plan allows for the granting of incentive and nonqualified options to purchase shares of common stock, restricted stock and other equity awards. Incentive options granted to employeesEmployee grants under the Plans generally vest over a threethree- to five-year period, with20%-33% vesting on the first anniversary of the date of grant and the remainder vesting in equal yearly installments thereafter. Nonqualified options issued tonon-employee directors and consultants under the Plans generally vest over one year. In the first quarter of 2018, to create a longer-term retention incentive, the Company’s Compensation Committee granted long-term incentive compensation awards to its Chief Executive Officer consisting of both stock options and restricted stock units (“RSUs”) that are subject to time-based vesting over nine years. Options granted under the Plans have a maximum term of ten years from the date of grant and generally, the exercise price of the stock options equals the fair market value of the Company’s common stock on the date of grant. At December 31, 2016,2018, options to purchase 1,236,586998,226 shares and 705,413 RSUs were outstanding under the Plans. At December 31, 2016, 1,821,576 shares were available for future grant under the 2012 Plan.

The Company uses the Black-Scholes option pricing model to calculate the fair value of share-basedstock option awards on the grant date.date, and the Company uses the value of the common stock as of the grant date to value RSUs. The Company measures stock-based compensation cost at the grant date based on the estimated fair value of the award. The Company recognizes expense on awards with service-based vesting over the employee’s requisite service period on a straight-line basis. In the third quarter of 2017, the Company issued performance stock units to certain employees related to the Spectrum Acquisition which are tied to the achievement of certain revenue and gross margin metrics and the passage of time. Additionally, in the first quarter of 2018, the Company issued performance stock units to certain individuals which are tied to the achievement of certain 2018 revenue metrics and the passage of time. The Company recognizes expense on performance-based awards over the vesting period based on the probability that the performance metrics will be achieved. The Company recognizes stock-based compensation expense for options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted for estimated forfeitures. The fair value of share-based awards granted during the years ended December 31, 2016, 20152018, 2017 and 20142016 were calculated using the following estimated assumptions:

On May 24, 2016, the Company issued $115$115.0 million aggregate principal amount of its 2.125% Convertible Senior Notes due 2021 (the “Notes”).Notes. The net proceeds from the sale of the Notes, after deducting the underwriting discounts and commissions and other related offering expenses, were approximately $111.1 million. The Notes bear interest at the rate of 2.125% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2016.

The Notes will mature on June 1, 2021, unless earlier repurchased, redeemed or converted in accordance with their terms. Prior to March 1, 2021, the Notes will be convertible at the option of holders of the Notes only upon satisfaction of certain conditions and during certain periods, and thereafter, the notesNotes will be convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the Notes will receive shares of the Company’s common stock, cash or a combination thereof, at the Company’s election. It is the Company’s current intent and policy to settle all conversions through combination settlement, which involves satisfying the principal amount outstanding with cash and any note conversion value over the principal amount in shares of the Company’s common stock.

Notes with a par value of $11,000 were submitted for conversion in the fourth quarter of 2017, and this conversion was settled in the first quarter of 2018. The conversion resulted in the issuance of a nominal-amount of shares of the Company’s common stock, and the Company recorded a loss of $1,000 on the conversion of these Notes.

During the fourth quarter of 2018, the closing price of the Company’s common stock continued to exceed 130% of the conversion price of the Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the Notes are convertible at the option of the holders of the Notes during the first quarter of 2019, the quarter immediately following the quarter when the conditions were met, as stated in the terms of the Notes. These terms have been met each quarter since the second quarter of 2018 and, expecting to continue meeting these terms, the Company reclassified the carrying value of the Notes from long-term liabilities to current liabilities on the Company’s consolidated balance sheet as of June 30, 2018. As of December 31, 2018, the if- converted value of the Notes exceeded the aggregate principal amount by $69.6 million. As of the date of this filing, no Notes were converted by the holders of such Notes in the first quarter of 2019. In the event the closing price conditions are met in the first quarter of 2019 or a future fiscal quarter, the Notes will be convertible at a holder’s option during the immediately following fiscal quarter.

The conversion rate for the Notes will initially be 31.1813 shares of the Company’s common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $32.07 per common share, and is subject to adjustment under the terms of the Notes. Holders of the Notes may require the Company to repurchase their Notes upon the occurrence of a fundamental change prior to maturity for cash at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The Company will not have the right to redeem the Notes prior to June 5, 2019, but may redeem the Notes, at its option, in whole or in part, on any business day on or after June 5, 2019 and prior to the maturity date if the last

reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect

for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides written notice of redemption. The redemption price will be equal to 100% of the principal amount of the principal amount of Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date.

The Notes contain customary terms and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the holders of at least 25% in aggregate principal amount of the outstanding Notes may declare 100% of the principal of, and any accrued and unpaid interest on, all of the Notes to be due and payable. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal of and accrued and unpaid interest, if any, on all of the Notes will become due and payable automatically. Notwithstanding the foregoing, the Notes provide that, to the extent the Company elects and for up to 270 days, the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants consist exclusively of the right to receive additional interest on the Notes. The Company is not aware of any events of default, current events or market conditions that would allow holders to call or convert the Notes as of December 31, 2016.2018.

The cash conversion feature of the Notes required bifurcation from the Notes and was initially accounted for as an equity instrument classified to stockholders’ equity, as the conversion feature was determined to be clearly and closely related to the Company’s stock. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and asset base and with similar maturity, the Company estimated the implied interest rate, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the Notes, which resulted in a fair value of the liability component of $96,289,000$96.3 million upon issuance, calculated as the present value of implied future payments based on the $115 million aggregate principal amount. The equity component of the Notes was recognized as a debt discount, recorded in additionalpaid-in capital, and represents the difference between the aggregate principal of the Notes and the fair value of the Notes without conversion option on their issuance date. The debt discount is amortized to interest expense using the effective interest method over five years, or the life of the Notes. The Company assesses the equity classification of the cash conversion feature quarterly, and it is not remeasuredre-measured as long as it continues to meet the conditions for equity classification.

Interest expense recognized on the Notes in 2018 was $2.4 million, $3.6 million and $0.6 million for the contractual coupon interest, the accretion of the debt discount and the amortization of the debt issuance costs, respectively. Interest expense recognized on the Notes during the year ended December 31, 20162017 includes $1,473,000, $1,934,000$2.4 million, $3.4 million and $340,000$0.6 million for the contractual coupon interest, the accretion of the debt discount and the amortization of the debt issuance costs, respectively. The effective interest rate on the Notes is 6.6%, which includes the interest on the Notes, amortization of the debt discount and debt issuance costs. As of December 31, 2016,2018, the carrying value of the Notes was approximately $95.3$103.5 million and the fair value of the principal was approximately $135.6$184.6 million. The fair value of the Notes was determined based on the most recent trade activity of the Notes as of December 31, 2016.2018.
