You should carefully read Item 1A - “Risk Factors” included in this Annual Report on Form 10-K to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements. Please also see the section entitled “Special Note Regarding Forward-Looking Statements and Industry Data.”

Overview

We are an ophthalmic medical technology and pharmaceutical company focused on developing novel therapies for the treatment of glaucoma, corneal disorders, and retinal disease. We first developed Micro-Invasive Glaucoma Surgery (MIGS) as an alternative to the traditional glaucoma treatment paradigm, launching our first MIGS device commercially in 2012, and have since developed a portfolio of technologically distinct and leverageable platforms to support ongoing pharmaceutical and medical device innovations. Products or product candidates for each of these platforms are designed to advance the standard of care through better treatment options across the areas of glaucoma, corneal disorders such as keratoconus, dry eye and refractive vision correction, and retinal diseases such as neovascular age-related macular degeneration (AMD), diabetic macular edema (DME), and retinal vein occlusion (RVO).

Impact of COVID-19 Pandemic and Current Economic Environment

While the COVID-19 pandemic and subsequent economic slowdown materially impacted the global demand for our products starting in March 2020, we began to see an early recovery toward more normalized levels for cataract and keratoconus procedures as early as May 2020, a trend that has generally continued, with periodic volatility in certain geographies in which we operate, through December 31, 2021. Most recently the Omicron variant has led to a material increase in diagnosed cases worldwide, creating new government restrictions in select geographies and impacting elective procedures in hospital and ambulatory surgery center sites. Additionally, the COVID-19 pandemic has led to widespread staffing shortages, including in ambulatory surgery centers, which may also impact elective procedures. These trends accelerated at the end of December 2021 and continued through the date herein.

We continue to actively assess the impact of COVID-19 on our clinical trials and other pipeline products. The closure of ophthalmic practices and deferral of elective procedures beginning in the first quarter of 2020 in response to COVID-19 disrupted new patient enrollment in our ongoing clinical trials. While we cannot predict the full impact of COVID-19 on the timing of completion of our clinical trials and the expected regulatory approvals for our pipeline products, our disclosed targeted approval dates anticipate, to our best estimate, such impact.

Additionally, some of our vendors are continuing to experience supply challenges, both in the acquisition of raw materials as well as due to limited headcount resources, and we have experienced higher costs for certain raw materials. These challenges have led to delays and partial or unfulfilled deliveries of certain components needed for the manufacture of our products, in some cases requiring us to find second sources for materials. If these delays and partial or unfulfilled deliveries persist, they could impact our ability to ship some of our products to our customers, or bring some of our pipeline products to market, in a timely manner. We believe that much of these supply challenges stem from the ongoing obstacles presented by COVID-19.

In 2020, when COVID had its greatest financial impact to date, we sought to preserve our cash position by instituting a number of cost saving initiatives, including temporary reductions in discretionary spending and capital expenditures. We temporarily deferred a significant portion of our planned 2020 capital expenditures, particularly those related to facilities expansion and consolidation plans, which were reinstituted as state and local governments began to

authorize re-openings. Further, in June 2020, we issued an aggregate principal amount of $287.5 million of 2.75% convertible notes due 2027 (the Convertible Notes), the net proceeds of which will be used for working capital and general corporate purposes. As of December 31, 2021, we had cash, cash equivalents, short-term investments, and restricted cash of approximately $423.5 million, compared to $413.9 million as of December 31, 2020.

The ultimate impact of the COVID-19 pandemic on our operations going forward is unknown and will depend on future developments which are highly uncertain and cannot be predicted with confidence, including the duration and severity of the COVID-19 outbreak, the status of health and safety actions taken to contain its spread, the severity and transmission rates of new variants of COVID-19 such as the Delta and Omicron variants, the availability, distribution, and efficacy of vaccines for COVID-19, any additional preventative and protective actions that governments, or we, may take, any future surges of COVID-19 that may occur, the dynamics associated with the rollout of the COVID-19 vaccines, and how quickly and to what extent economic and operating conditions normalize within the markets in which we operate. For additional information, see the section titled Risks Related to Our Business within Item 1A. Risk Factors of this Annual Report on Form 10-K.

Financial Overview

The most important financial indicators that we use to assess our business are net sales, gross margin, operating expenses, and cash on hand.

Gross margin 77 % 59 %

Please see Results of Operations and Liquidity and Capital Resources below for a detailed discussion of each of the above items including analysis of the fluctuations from year to year.

We incurred net losses of $49.6 million and $120.3 million for the years ended December 31, 2021 and December 31, 2020, respectively and as of December 31, 2021, we had an accumulated deficit of $365.2 million.

Material Changes and Transactions

Acquisition of Avedro, Inc.

On November 21, 2019, we acquired Avedro, Inc. (Avedro), a hybrid ophthalmic pharmaceutical and medical technology company focused on developing therapies designed to treat corneal diseases and disorders and correct refractive conditions, in a stock-for-stock transaction (Avedro Merger). Avedro developed novel bio-activated drug formulations used in combination with proprietary systems for the treatment of progressive keratoconus and corneal ectasia following refractive surgery. The therapy is the first and only minimally invasive anterior segment product offering approved by the FDA shown to halt the progression of keratoconus.

Recent Developments

2022 U.S. reimbursement rates

On November 2, 2021, the United States (U.S.) Centers for Medicare & Medicaid Services (CMS) published its final rules for 2022 Medicare physician fee payment rates and 2022 Medicare facility fee payment rates for services furnished in both the ambulatory surgery center and hospital outpatient settings (Final Rules). These Final Rules superseded the proposed rates that were issued by CMS in July 2021 which were much lower than the rates issued in the Final Rules. Compared to the 2021 reimbursement rates, the Final Rules contained a new, significantly lower physician fee related to the implantation of trabecular bypass stents, such as our iStent family of products, in conjunction with cataract surgery. Conversely, the facility fee schedule related to surgeries that include implantation of trabecular bypass

Table of Contents

stents, such as our iStent family of products, in conjunction with cataract surgery, slightly decreases reimbursements to an ambulatory surgery center and increases reimbursements to a hospital. We estimate that approximately 80% of procedures utilizing our trabecular micro-bypass technologies in the U.S. are performed in the ambulatory surgery center setting and the remaining estimated 20% of procedures are performed in the hospital. Additionally, the Final Rules established facility fee payment rates that were lower than anticipated for standalone insertion of an aqueous drainage device in the ambulatory surgery center and hospital settings, which would be the procedure that such facilities would use with our iStent infinite product, which is not yet approved by the FDA. These CMS reimbursement rates contained in the Final Rules took effect January 1, 2022.

U.S. glaucoma volumes were negatively impacted during the third and fourth quarter of 2021 as typical customer ordering patterns were disrupted and trialing of competitive products increased in anticipation of the potential 2022 CMS physician and facility fee reimbursement rate decreases becoming effective as originally proposed in July 2021. The physician fee reimbursement rate as issued in the Final Rules may continue to have an adverse impact on 2022 procedural iStent family product volumes, in conjunction with cataract surgery, as well as on our 2022 U.S. combo-cataract glaucoma revenues, gross profit, and net income, the full extent of which is not known at this time.

Attillaps License Agreement

On September 20, 2021, we announced that we had entered into a licensing agreement (Attillaps License Agreement) with Attillaps Holdings, Inc. (Attillaps) under which Attillaps granted us a global exclusive license to Attillaps’ proprietary library of investigational pharmaceutical compounds that target the eradication of Demodex mites, which are the root cause of Demodex blepharitis and often associated with meibomian gland dysfunction and related ophthalmic diseases. Under the Attillaps Licensing Agreement, we have the exclusive global right to research, develop, manufacture and commercialize products using certain acetylcholinesterase inhibitors for the treatment of ophthalmic diseases caused by Demodex mites. We paid $5.0 million upon the signing of the Attillaps License Agreement and will have ongoing milestone and royalty payment obligations depending on the success of the development, approval and commercialization of the compounds.

Settlement of Patent Litigation

On September 14, 2021, we entered into a settlement agreement (Settlement Agreement) with Ivantis, Inc. (Ivantis), pursuant to which we and Ivantis agreed to terminate the patent infringement lawsuit we had filed against Ivantis on April 14, 2018 in the U.S. District Court for the Central District of California, Southern Division (the Lawsuit). In the Lawsuit, we alleged that Ivantis’ Hydrus® Microstent device infringes our U.S. Patent Nos. 6,626,858 and 9,827,143. Pursuant to the terms of the Settlement Agreement, Ivantis has made cash payments totaling $60.0 million, $30.0 million of which was paid to us during the year ended December 31, 2021, and $30.0 million of which was paid to us in January 2022.

Additionally, Ivantis will make quarterly royalty payments to us in the amount of 10% of Ivantis’ Hydrus Microstent U.S. sales and any international sales supplied out of the U.S. beginning in the fourth quarter of 2021 through April 26, 2025, subject to a per-unit minimum payment. We and Ivantis have dismissed with prejudice all of our claims against each other in the Lawsuit, which was scheduled for trial beginning on or around September 28, 2021, and in related lawsuits in other forums and jurisdictions. The parties also have agreed to mutual licenses and covenants not to sue the other party for patent infringement relating to Ivantis’ Hydrus Microstent or our micro-stent devices.

Santen License Agreement

On May 18, 2021, we announced that we entered into a new development and commercialization license agreement with Santen Pharmaceutical Co., Ltd. (Santen) for the PreserFlo MicroShunt, superseding the previous collaboration and distribution agreements between the two parties. Under the new agreement, we obtain exclusive commercialization rights for the MicroShunt in the United States, Australia, New Zealand, Canada, Brazil, Mexico and the remainder of Latin America. The new agreement also provides us with control over development activities for the MicroShunt in these same territories, including clinical development and regulatory affairs activities in the United States following a transition period. Santen submitted a premarket approval (PMA) application to the U.S. Food and Drug Administration (FDA) in June 2020 and discussions with the FDA remain ongoing. We did not make any payment in connection with the execution of the license agreement; however, should we be successful in obtaining regulatory

Table of Contents

approval for the PreserFlo MicroShunt, we would be required to pay Santen a milestone payment, followed by royalties and other potential future milestones depending on the success of the commercialization of the product.

Intratus License Amendment

On April 14, 2021, we announced that we had entered into an amended licensing agreement with Intratus, Inc. (Intratus) under which Intratus granted us a global exclusive license to research, develop, manufacture and commercialize Intratus’ patented, non-invasive drug delivery platform for application in the treatment of presbyopia. The addition of presbyopia expands upon the existing agreement between us and Intratus announced on July 22, 2019. The amendment includes a mechanism to further expand the existing agreement to other indications, applying the active pharmaceutical ingredients being advanced by us in glaucoma, corneal disorders and presbyopia to new ophthalmic fields.

Factors Affecting Our Performance

In addition to the disruption resulting from COVID-19 as discussed above, the full effects of which are difficult to predict at this time, our operations to date have been, and we believe our future growth will be, impacted by the following:

Further, we have made and expect to continue to make significant investments in our global sales force, marketing programs, research and development (R&D) activities, clinical studies, and general and administrative infrastructure. FDA-approved investigational device exemption (IDE) or investigational new drug (IND) studies and new product development programs in our industry are expensive. Our operating expenses have increased significantly following our acquisition of Avedro, and we also have incurred additional construction costs related to our new facility in Aliso Viejo, California (Aliso Facility).

We expect 2022 revenues and near-term performance to reflect increasing competitive dynamics, the impact of the reduced physician fee reimbursement rates contained in the CMS Final Rules and the continuing disruption resulting from COVID-19, the full effects of which are difficult to predict at this time.

Although we have been profitable for certain periods in our operating history, there can be no assurance that we will be profitable or generate cash from operations in the future.

Components of Results of Operations

Net Sales

We currently operate in one reportable segment and net sales are generated primarily from sales of iStent products and sales of Photrexa and other associated drug formulations, as well as our proprietary bioactivation systems, to customers and royalty income. Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration to which we expect to be entitled in exchange for those products or services.

We sell the majority of our products through a direct sales organization in the United States. Internationally, we sell our products primarily through direct sales subsidiaries in seventeen countries and through independent distributors in certain countries in which we do not have a direct presence or maintain a modest commercial presence. The primary end-user customers for our products are surgery centers, hospitals and physician private practices.

While net sales may increase as we expand our global sales and marketing infrastructure and continue to increase awareness of our products by expanding our sales base and increasing our marketing efforts, historically our net sales within a fiscal year have been impacted seasonally, as demand for U.S. ophthalmic procedures is typically softer in the first quarter and stronger in the fourth quarter of a given year. However, we have not experienced the same seasonality pattern in 2021 due in part to the COVID-19 pandemic and its effect on our commercial performance may continue into future reporting periods. We also believe the 2022 CMS physician fee and facility fee rate decreases, which were finalized in the fourth quarter 2021, have disrupted traditional customer ordering patterns and have resulted in our customers’ trialing of competitive products, causing reduced U.S. Glaucoma sales volumes during our third and fourth quarter of 2021. Additionally, for several years we had commercialized our products in the U.S. with few or no direct competitors. Other products have now become available in the U.S. and globally, or are in development by third parties, that have entered or could enter the market and which may affect adoption of or demand for our products. These other products could achieve greater commercial acceptanceor demonstrate better safety or effectiveness, clinical results, ease of use or lower costs than our products, which could adversely impact our net sales.

Cost of Sales

Cost of sales reflects the aggregate costs to manufacture our products and includes raw material costs, labor costs, manufacturing overhead expenses and the effect of changes in the balance of reserves for excess and obsolete inventory.

We manufacture our iStent products at our current headquarters in San Clemente, California using components manufactured by third parties. We manufacture our KXL systems at our manufacturing facilities in Burlington, Massachusetts, and we contract with third-party manufacturers in the U.S. and Germany to produce our Photrexa and other associated drug formulations.

Due to the relatively low production volumes of our iStent products and our KXL systems compared to our potential capacity for those products, a significant portion of our per unit costs is comprised of manufacturing overhead expenses. These expenses include quality assurance, material procurement, inventory control, facilities, equipment and operations supervision and management.

Cost of sales includes a charge equal to a low single-digit percentage of worldwide net sales of certain current and future products, including our iStent products, with a required minimum annual payment of $0.5 million, which amount became payable to the Regents of the University of California (the University) in connection with our December 2014 agreement with the University (the UC Agreement) related to a group of our U.S. patents (the Patent Rights). This ongoing product payment obligation will change as patent coverage on certain products being to lapse, and will terminate entirely on the date the last of the Patent Rights expires, which is currently expected to be in the fourth quarter of 2022.

Cost of sales has included amortization of the $252.2 million developed technology intangible asset recognized in connection with the Avedro Merger. For each of the years ended December 31, 2021 and December 31, 2020, the amortization expense was $22.1 million, and for the year ended December 31, 2019, the amortization expense was $2.3

Table of Contents

million. Additionally, cost of sales included amortization of the fair market value inventory adjustment recorded in connection with the Avedro Merger, which for the years ended December 31, 2020 and December 31, 2019 was $24.7 million and $4.0 million, respectively, and was fully amortized as of December 31, 2020.

Our future gross profit as a percentage of net sales, or gross margin, will be impacted by numerous factors including commencement of sales of products in our pipeline, or any other future products, which may have higher product costs. Our gross margin will also be affected by manufacturing or supply chain inefficiencies that we may experience as we attempt to manufacture our products on a larger scale, manufacture new products and change our manufacturing capacity or output. Additionally, our gross margin will continue to be affected by royalty expenses on current or future products associated with various licensing agreements. Other factors adversely affecting our net sales in future periods, including the impact of the COVID-19 pandemic and any related supply chain issues, and the impact of reductions by CMS in 2022 Medicare payment rates for certain of our products and related services, may also impact our gross profit margins in future periods.

Selling, General and Administrative

Our selling, general and administrative (SG&A) expenses primarily consist of personnel-related expenses, including salaries, sales commissions, bonuses, fringe benefits and stock-based compensation for our executive, financial, marketing, sales, and administrative functions. Other significant SG&A expenses include marketing programs; advertising; post-approval clinical studies; conferences and congresses; travel expenses; costs associated with obtaining and maintaining our patent portfolio; professional fees for accounting, auditing, consulting and legal services; costs to implement our global enterprise systems; and allocated overhead expenses.

We expect SG&A expenses to continue to grow as we increase our global sales and marketing infrastructure and general administration infrastructure in the United States. We also expect other nonemployee-related costs, including sales and marketing program activities for new products, outside services and accounting and general legal costs to increase as our overall operations grow. The timing of these increased expenditures and their magnitude are primarily dependent on the commercial success and sales growth of our products, as well as on the timing of any new product launches and other potential business and operational activities.

Research and Development

Our R&D activities primarily consist of new product development projects, pre-clinical studies, IDE and IND studies, and other clinical trials. Our R&D expenses primarily consist of personnel-related expenses, including salaries, fringe benefits and stock-based compensation for our R&D employees; research materials; supplies and services; and the costs of conducting clinical studies, which include payments to investigational sites and investigators, clinical research organizations, consultants, and other outside technical services and the costs of materials, supplies and travel. We expense R&D costs as incurred. We expect our R&D expenses to continue to increase as we initiate and advance our development programs, including our expanding surgical, pharmaceutical and intraocular sensor development efforts and clinical trials across glaucoma, retinal disease and corneal health.

Completion dates and costs for our clinical development programs include seeking regulatory approvals and our research programs vary significantly for each current and future product candidate and are difficult to predict. As a result, while we expect our R&D costs to continue to increase for the foreseeable future, we cannot estimate with any degree of certainty the costs we will incur in connection with the development of our product candidates. We anticipate we will make determinations as to which programs and product candidates to pursue and how much funding to direct to each program and product candidate on an ongoing basis in response to the scientific success of early research programs, results of ongoing and future clinical trials, as well as ongoing assessments as to each current or future product candidate’s commercial potential and our likelihood of obtaining necessary regulatory approvals. We are not currently able to fully track expenses by product candidate.

Table of Contents

In-process Research and Development

Our in-process research and development (IPR&D) expenses relate to the amendment of our exclusive licensing agreement with Intratus, Inc. and our Attillaps License Agreement. Upfront payments of $5.0 million were made in connection with each of these agreements and were expensed to IPR&D as management determined there were no alternative future uses for the technology acquired.

Litigation-related Settlement

Pursuant to the terms of the Settlement Agreement, Ivantis paid us $30.0 million during the year ended December 31, 2021. The $30.0 million cash payment received during the year ended December 31, 2021 is included in litigation-related settlement as a reduction of operating expenses on the consolidated statements of operations.

Non-Operating (Expense) Income, Net

Non-operating (expense) income, net primarily consists of interest expense associated with our finance lease for our Aliso Facility and for our Convertible Notes, interest income derived from our short-term investments and unrealized gains and losses arising from exchange rate fluctuations on transactions denominated in a currency other than the U.S. dollar, primarily related to intercompany loans.

Income Taxes

Our tax provision is primarily comprised of state and foreign income taxes. Our net deferred tax liability of $7.3 million at December 31, 2021 represents the excess of our indefinite-lived deferred tax liabilities over our indefinite-lived deferred tax assets. We continue to provide a full valuation allowance against our other net deferred tax assets.

We record reserves for uncertain tax positions where we believe the ability to sustain the tax position does not reach a more likely than not threshold.

Net Sales

Our net sales are generated primarily from sales of iStent products to customers and sales of Photrexa and associated drug formulations as well as KXL systems to customers. Customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with distributors being used in certain international locations where we currently do not have a direct commercial presence.

Net sales for the years ended December 31, 2021 and December 31, 2020 were $294.0 million and $225.0 million, respectively, reflecting an increase of $69.0 million or 31%.

Net sales of glaucoma products in the U.S. were $170.8 million and $133.7 million for the years ended December 31, 2021 and December 31, 2020, respectively, increasing by approximately 28% primarily due to the demand for combined cataract and glaucoma procedures increasing during the year ended December 31, 2021 as compared to the year ended December 31, 2020 given a return to more normalized procedure levels following the rollout of the COVID-19 vaccines, a trend that generally continued throughout 2021, with periodic demand volatility in certain geographies in which we operate. We also believe the 2022 CMS physician fee and facility fee rate decreases that were proposed in July 2021 disrupted traditional customer ordering patterns and resulted in our customers’ trialing of competitive products.

International sales of glaucoma products for the years ended December 31, 2021 and December 31, 2020 were $61.2 million and $45.6 million, respectively, increasing by approximately 34%. The increase in international sales reflects growing demand in many key international markets for combined cataract and glaucoma procedures during the year ended December 31, 2021 as compared to the year ended December 31, 2020 given a return to more normalized procedure levels following the rollout of the COVID-19 vaccines, a trend that generally continued throughout 2021, with periodic demand volatility in certain international geographies in which we operate, and favorable foreign exchange rates compared to the prior year.

Net sales of corneal health products were $62.0 million and $45.6 million for the years ended December 31, 2021 and December 31, 2020, respectively, increasing by 36%.The $16.4 million increase in net sales generated from our corneal health products was comprised of an increase of approximately $13.6 million in U.S. sales using direct sales operations and an increase of $2.8 million internationally where we utilize distributors given we do not have a direct commercial presence, due to these distributors returning to their more stabilized pre-COVID ordering patterns. The $13.6 million increase in U.S. sales of corneal health products includes an increase of approximately $14.7 million of Photrexa net sales, partially offset by reductions of approximately $1.1 million in U.S. capital equipment sales. Sales of corneal health products in 2020 were negatively impacted by disruption resulting from COVID-19. Demand for corneal health products increased during the year ended December 31, 2021 given a return to more normalized procedure levels following the rollout of the COVID-19 vaccines, a trend that generally continued throughout 2021. Additionally, corneal health sales for the year ended December 31, 2021 were positively impacted by higher realized average sales and continued new account starts.

Cost of Sales

Cost of sales for the years ended December 31, 2021 and December 31, 2020 were $66.6 million and $91.7 million, respectively, reflecting a decrease of approximately $25.1 million or 27%. The decrease was primarily comprised of a decrease of approximately $24.7 million related to the acquisition fair market value inventory adjustment rollout that was fully amortized as of December 31, 2020, and a decrease of approximately $2.3 million, net related to the acquisition fair market value inventory adjustment recorded in 2020 in connection with the Avedro Merger that was fully amortized as of December 31, 2020. These decreases were partially offset by normal increases in cost of sales due to higher net sales for the year ended December 31, 2021 as compared to the year ended December 31, 2020. Our gross margin was approximately 77% for the year ended December 31, 2021 compared to approximately 59% for the year ended December 31, 2020. The increased gross margin resulted primarily from the increased net sales during the year ended December 31, 2021 as discussed above, the aforementioned fair market value inventory adjustment and, to a lesser extent, changes in product mix, most notably the inclusion of modestly lower margin products related to international market sales.

Selling, General and Administrative Expenses

SG&A expenses for the years ended December 31, 2021 and December 31, 2020 were $179.3 million and $171.4 million, respectively, reflecting an increase of $7.9 million or 5%.

Of the total $179.3 million, approximately $102.6 million was comprised of compensation and related employee expenses, with the remaining $76.7 million spent on our marketing programs, advertising, post-approval clinical studies, conferences and congresses, travel expenses, costs associated with obtaining and maintaining our patent portfolio, and professional fees for accounting, auditing, consulting and legal services.

We incurred approximately $112.4 million and $98.2 million in commercial personnel and discretionary spending in the years ended December 31, 2021 and December 31, 2020, respectively, related primarily to existing sales infrastructure in glaucoma and corneal health. We also incurred approximately $66.8 million and $73.1 million of general and administrative personnel and discretionary spending for the years ended December 31, 2021 and December 31, 2020 associated with our ongoing administrative functions and amortization of our right-of-use asset related to our long-term lease for the Aliso Facility.

The above increase in SG&A expenses for the year ended December 31, 2021 was due to a return toward more normalized levels of spending to support increased demand for glaucoma and keratoconus procedures in certain key geographic markets in which we operate, relative to the year ended December 31, 2020, when we incurred temporary reductions in compensation and related employee expenses for our executive team, senior leadership, and many others throughout the company, and reduced professional services expenses as part of cost-savings measures in response to the COVID-19 pandemic. These increases in SG&A expenses during the year ended December 31, 2021 compared to the year ended December 31, 2020 were partially offset by approximately $5.2 million in decreased patent infringement expenses, $6.6 million in decreased stock-based compensation associated with the various stock option and restricted stock awards we granted in connection with the Avedro Merger, $2.2 million in decreased sales tax reserve and a decrease of approximately $1.5 million for costs incurred for restructuring and integration expenses related to the Avedro Merger.

Research and Development Expenses

R&D expenses for the years ended December 31, 2021 and December 31, 2020 were $101.0 million and $85.4 million, respectively, reflecting an increase of $15.6 million or 18%.

We incurred $66.6 million in core R&D expenses and $34.4 million in clinical expenses, comprised of $50.1 million in compensation and related employee expenses with the remaining $50.9 million spent on the continued research and development, clinical studies, regulatory activities, quality assurance, clinical inventory and supplies for surgical glaucoma product candidates and pharmaceutical projects, such as a pharmaceutical therapeutic system for the treatment of keratoconus without the removal of the epithelium (often referred to as “epi-on”), iDose and our earlier stage programs fordry eye, presbyopia, retina and other therapeutic investments.

In-Process Research and Development

IPR&D expenses for the year ended December 31, 2021 related to the amendment of our exclusive licensing agreement with Intratus and our Attillaps License Agreement. We paid $5.0 million upon signing of each of these agreements. There were no IPR&D expenses during the year ended December 31, 2020.

Litigation-related Settlement

The $30.0 million cash payment from the Settlement Agreement received during the year ended December 31, 2021 is included in litigation-related settlement as a reduction of operating expenses on the consolidated statements of operations.

Non-Operating (Expense) Income, Net

We had non-operating expense, net of $16.4 million and $8.8 million for the years ended December 31, 2021 and December 31, 2020, respectively. The increase in non-operating expense, net primarily relates to interest expense

Table of Contents

recognized related to the Convertible Notes and to the finance lease for our Aliso Facility, as well as recognition of unrealized foreign currency losses due to higher intercompany loan balances denominated in, and impacted by, changes in foreign currency exchange rates.

Income Tax Provision (Benefit)

Our effective tax rate for the year ended December 31, 2021 was not meaningful. For the year ended December 31, 2021 and December 31, 2020, we recorded a provision/(benefit) for income taxes of $0.3 million and $(12.0) million, respectively. For the year ended December 31, 2021, our tax provision was primarily comprised of state and foreign income taxes. For the year ended December 31, 2020, our tax benefit resulted from the issuance of the Convertible Notes partially offset by state and foreign income taxes.

Liquidity and Capital Resources

Our principal sources of liquidity are our existing cash, cash equivalents and short-term investments, cash generated from operating, financing and investing activities and proceeds from our senior convertible notes issuance. Our primary uses of cash have been for selling and marketing activities, research and development programs, and capital expenditures.

The following table summarizes our cash and cash equivalents, short-term investments and selected working capital data as of December 31, 2021 and December 31, 2020 (in thousands):

December 31, December 31,

Main Sources of Liquidity

We plan to fund our operations, commitments for capital expenditures and other short and long-term known contractual and other obligationsusing existing cash and investments and, to the extent available, cash generated from commercial operations. Our existing cash and investments include the remaining net proceeds from the Convertible Notes issued in June 2020 (after payment for the related capped call transactions), and the $30.0 million payment by Ivantis during the year ended December 31, 2021, which is being used for working capital and general corporate purposes. See above in the Material Changes and Transaction section of Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Cash, Cash Equivalents, Short-term Investments and Restricted Cash

Our cash, cash equivalents and short-term investments totaled approximately $414.1 million and our restricted cash totaled approximately $9.4 million.

Cash Flow from Operations

For the twelve months ended December 31, 2021, we had positive cash inflows of $24.7 million from operating activities.

Senior Convertible Notes

Our Convertible Notes may be converted at the option of the holders at the times and under the circumstances and at the conversion rate described in Note 8 of the notes to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K. As of December 31, 2021, none of the conditions allowing holders of the Convertible Notes to convert had been met. These conditions are measured each quarter. For example, if our trading price remains above 130% of the conversion price for at least 20 trading days during the 30 consecutive trading-day period ending on, and including, March 31, 2022, holders of the Convertible Notes would have the right to convert their Convertible Notes during the calendar quarter beginning April 1, 2022. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, in the manner and subject to the terms and conditions provided in the Indenture. Settling all or a portion of the conversion obligation in cash could adversely affect our liquidity. In addition, even if holders of the Convertible Notes do not elect to convert their Convertible Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

We may seek to obtain additional financing in the future through other debt or equity financings. There can be no assurance that we will be able to obtain additional financing on terms acceptable to us, or at all and although we have been profitable for certain periods in our operating history, there can be no assurance that we will be profitable or generate cash from operations.

Short-term Liquidity Requirements

Our short-term liquidity requirements primarily consist of regular operating costs, interest payments related to our senior convertible notes, funding R&D projects, capital expenditures for the development of our facilities and office spaces as we continue our development of our Aliso Facility, and short-term material cash requirements as described below. As of December 31, 2021, we had net working capital of $422.8 million, which indicates that our current assets are more than enough to cover our short-term liabilities.

Long-term Liquidity Requirements

Our long-term liquidity requirements primarily consist of interest and principal payments related to our senior convertible notes, capital expenditures for the development of our manufacturing facilities and office spaces, and long-term material cash requirements as described below. As demand grows for our products, we will continue to expand global operations to meet demand through investments in manufacturing and operations.

Material Cash Requirements

The following table summarizes our material cash requirements, including commitments for capital expenditures and known contractual and other obligations as of December 31, 2021, and the amount required to satisfy those requirements in future periods.

After funding the current operations of our commercial activities, the first planned use of our cash flow from operations is to provide capital funding for our R&D and clinical activities. In addition to investing in R&D and clinical activities, we expect to utilize cash for various capital expenditures including the expansion and enhancement of our

Table of Contents

facilities. We have made and expect to continue to make significant investments in our global sales force, marketing programs, research and development activities, clinical studies and general and administrative infrastructure. FDA-approved IDE and IND studies and new product development programs in our industry are expensive.

We believe that cash from operating, financing and investing activities, together with our cash and investment balances, will be sufficient to meet ongoing operations, capital expenditures, commitments, working capital requirements and other known contractual and other obligations and satisfy our liquidity requirements for at least the next 12 months and the foreseeable future.

Cash Flows

Our historical cash outflows have primarily been associated with cash used for operating activities such as the expansion of our sales, marketing and R&D activities; purchase of and growth in inventory and other working capital needs; the acquisition of intellectual property; and expenditures related to equipment and improvements used to increase our manufacturing capacity, to improve our manufacturing efficiency and for overall facility expansion.

The following table is a condensed summary of our cash flows for the periods indicated:

Year ended

December 31,

Net cash provided by (used in):

Exchange rate changes (1,774) (88)

At December 31, 2021, our cash and cash equivalents were held for working capital purposes. We do not enter into investments for trading or speculative purposes. Our policy is to invest any cash in excess of our immediate requirements in investments designed to preserve the principal balance and provide liquidity.

Operating Activities

In the year ended December 31, 2021 our operating activities provided $24.7 million and for the years ended December 31, 2020 our operating activities used $23.0 million.

For the year ended December 31, 2021, our net cash provided by operating activities reflected our net loss of $49.6 million, adjusted for non-cash items of $70.7 million, primarily consisting of stock-based compensation expense of $30.1 million, depreciation and amortization of $29.7 million, amortization of lease right-of-use assets of $4.8 million, and amortization of debt issuance costs of $1.4 million. This was partially offset by changes in operating assets and liabilities of $3.6 million, which resulted from increases in accounts payable and accrued liabilities and decreases in accounts receivable, partially offset by increases in inventory and prepaids and other current assets.

For the year ended December 31, 2020, our net cash used in operating activities reflected our net loss of $120.3 million, adjusted for non-cash items of $100.6 million, primarily consisting of stock-based compensation expense of $46.5 million, depreciation and amortization of $29.4 million, amortization of the inventory fair value adjustment as a result of the Avedro Merger of $24.7 million, amortization of lease right-of-use assets of $5.2 million, the fair value of cash-settled stock options of $3.2 million and a deferred income tax benefit of $12.2 million. This was offset by changes in operating assets and liabilities of $3.2 million, which resulted from decreases in accounts receivable, inventory, and other assets partially offset by decreases in accounts payable and accrued liabilities and increases in prepaid expenses and other assets.

Investing Activities

In the year ended December 31, 2021 and December 31, 2020 net cash from investing activities used approximately $58.2 million and $205.1 million, respectively.

In the year ended December 31, 2021, we used approximately $215.3 million for purchases of short-term investments, received proceeds from sales and maturities of short-term investments of $206.9 million and used approximately $2.1 million related to investments in company-owned life insurance.

In the year ended December 31, 2020, we used approximately $301.0 million for purchases of short-term investments, received proceeds from sales and maturities of short-term investments of $104.7 million and used approximately $1.8 million related to investments in company-owned life insurance.

Cash used for purchases of property and equipment was approximately $47.8 million and $6.9 million for the years ended December 31, 2021 and December 31, 2020, respectively.

We expect to increase our investment in property and equipment in the future as we expand our manufacturing capacity for current and new products, improve our manufacturing efficiency and for overall facility expansion, as discussed above.

Financing Activities

In the years ended December 31, 2021 and December 31, 2020 our financing activities provided $39.3 million and $262.5 million of net cash, respectively.

In the year ended December 31, 2021, we received $30.9 million from the exercises of stock options and purchases of our common stock by employees pursuant to our Employee Stock Purchase Plan and used $3.7 million for payment of employee taxes related to restricted stock unit vestings. Additionally, we received $12.7 million in proceeds from our tenant improvement allowances of our Aliso Facility and paid $0.7 million in principal on our finance lease.

In the year ended December 31, 2020, we received net cash proceeds of approximately $287.5 million related to our Convertible Notes, used $9.6 million for transaction costs related to the Convertible Notes and used $35.7 million on payment of the capped call transaction related to the Convertible Notes. We received net cash proceeds of approximately $24.2 million from the exercises of stock options and purchases of our common stock by employees pursuant to our Employee Stock Purchase Plan and used $3.9 million for payment of employee taxes related to restricted stock unit vestings.

In addition to the amounts included in the table above, there may be material cash obligations related to our Convertible Notes in the event they become convertible and are converted.

We do not have any significant off-balance sheet arrangements or holdings in variable interest entities.

Critical Accounting Policies and Significant Estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and related disclosure of contingent assets and liabilities, revenue and expenses at the date of the consolidated financial statements. Generally, we base our estimates on historical experience and on various other assumptions in accordance with GAAP that we believe to be reasonable under the circumstances. Actual results may differ materially from these estimates under different assumptions or conditions and such differences could be material to our financial position and results of operations.

Table of Contents

While our significant accounting policies are more fully described below and in the Notes to our consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe the following accounting policies to be most critical for fully understanding and evaluating our financial condition and results of operations.

Revenue Recognition

We derive our revenue from sales of our products in the United States and internationally. Customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with distributors being used in certain international locations where we do not have a direct commercial presence.

We concluded that one performance obligation exists for the majority of our contracts with customers which is to deliver products in accordance with our normal delivery times. Revenue is recognized when this performance obligation is satisfied, which is the point in time when we consider control of a product to have transferred to the customer. Revenue recognized reflects the consideration to which we expect to be entitled in exchange for those products or services. We have determined the transaction price to be the invoice price, net of adjustments, which includes estimates of variable consideration for certain product returns. We only recognize revenue when it is probable that we will collect the consideration we are entitled to in exchange for the goods transferred to a customer. This requires management to perform an assessment related to the probability of collecting the consideration. The assessment can contain judgment when it is performed for customers with declining credit conditions or those with no history or a limited history of product sales with us.

We offer volume-based rebate agreements to certain customers and, in these instances, we provide a rebate (in the form of a credit memo) at the contract’s conclusion, if earned by the customer. In such cases, the transaction price is allocated between our delivery of product and the issuance of a rebate at the contract’s conclusion for the customer to utilize on prospective purchases. The performance obligation to issue a customer’s rebate, if earned, is transferred over time and our method of measuring progress is the output method, whereby the progress is measured by the estimated rebate earned to date over the total rebate estimated to be earned over the contract period. The provision for volume-based rebates is estimated based on customers' contracted rebate programs and the customers’ projected sales levels. We periodically monitor our customer rebate programs to ensure the rebate allowance is fairly stated. Our rebate allowance is included in accrued liabilities in the consolidated balance sheets and estimated rebates accrued were not material during the periods presented.

Customers are not granted specific rights of return; however, we may permit returns of certain products from customers if such product is returned in a timely manner and in good condition. We generally provide a warranty on our products for one year from the date of shipment, and offer an extended warranty for our KXL systems. Any product found to be defective or out of specification will be replaced or serviced at no charge during the warranty period. Estimated allowances for sales returns and warranty replacements are recorded at the time of sale of the product and are estimated based upon the historical patterns of product returns matched against sales, and an evaluation of specific factors that may increase the risk of product returns. Product returns and warranty replacements to date have been consistent with amounts reserved or accrued and have not been significant. If actual results in the future vary from our estimates, we will adjust these estimates which would affect net product revenue and earnings in the period such variances become known.

Stock-Based Compensation Expense

Stock-based compensation expense for stock options is measured at the date of grant, based on the estimated fair value of the award using the Black-Scholes option pricing model.

Stock-based compensation expense for restricted stock units is also measured at the date of grant, based on the closing price of our common stock.

For awards subject to time-based vesting conditions, we recognize stock-based compensation expense over the requisite service period on a straight-line basis, net of estimated forfeitures.

Table of Contents

The estimation of the fair value of each stock-based option grant or issuance on the date of grant involves numerous assumptions by management. Although we calculate the fair value under the Black-Scholes option pricing model, which is a standard option pricing model, this model still requires the use of numerous assumptions, including, among others, the expected life (turnover), volatility of the underlying equity security, a risk free interest rate and expected dividends. During the year ended December 31, 2021 the Company based the expected volatility on a weighted average of the historical volatility of its common stock and historical volatilities of a peer group of similar companies over the most recent period commensurate with the estimated expected term of the Company’s stock options. During the years ended December 31, 2020 and 2019, the expected volatility assumption was based on historical volatilities of a peer group of similar companies whose share prices were publicly available. The peer group was developed based on companies in the biotechnology industry. We have estimated the expected term of our stock options using the “simplified” method, whereby the expected life equals the average of the vesting term and the original contractual term of the option. The use of different values by management in connection with these assumptions in the Black-Scholes option pricing model could produce substantially different results.

Recent Accounting Pronouncements

For a description of recent accounting pronouncements, see Note 2 of the notes to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

ITEM 7A.Quantitative and qualitative disclosures about market risk

Interest Rate Risk

We are exposed to market risks in the ordinary course of our business. Our cash and cash equivalents include cash in readily available checking and money market accounts, as well as a certificate of deposit. These securities are not dependent on interest rate fluctuations that could cause the principal amount of these assets to fluctuate and thus do not pose any interest rate risk to us. While we believe our cash and cash equivalents do not contain excessive risk, we cannot provide absolute assurance that in the future our investments will not be subject to adverse changes in market value.

In addition, we maintain significant amounts of cash and cash equivalents at one or more financial institutions that are in excess of federally insured limits.

Foreign Currency Exchange Risk

The financial statements of our foreign subsidiaries and their sales to customers are denominated in the foreign subsidiaries’ respective functional currencies, and therefore we have exposure to foreign currency exchange rates. The remainder of our business is primarily denominated in U.S. dollars. The effect of a 10% adverse change in exchange rates on foreign denominated cash, receivables and payables would not have been material for the periods presented. As our international operations grow, our results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which could harm our business in the future. To date, we have not entered into any material foreign currency hedging contracts although we may do so in the future.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Glaukos Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Glaukos Corporation (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive (loss) income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, 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), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 28, 2022 expressed an unqualified opinion thereon.

Adoption of ASU No. 2020-06

As discussed in Note 8 to the consolidated financial statements, the Company changed its method for accounting for convertible debt in 2021 due to the adoption of Accounting Standards Update (ASU) No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.

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 U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 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 included 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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective or complex judgments.

Notes to Consolidated Financial Statements

Note 1. Organization and Basis of Presentation

Organization and Business

Glaukos Corporation (Glaukos or the Company), incorporated in Delaware on July 14, 1998, is an ophthalmic medical technology and pharmaceutical company focused on developing novel therapies for the treatment of glaucoma, corneal disorders, and retinal disease. The Company developed Micro-Invasive Glaucoma Surgery (MIGS) to serve as an alternative to the traditional glaucoma treatment paradigm and launched its first MIGS device commercially in 2012. The Company also offers commercially a proprietary bio-activated pharmaceutical therapy for the treatment of a corneal disorder, keratoconus, that was approved by the U.S. Food and Drug Administration (FDA) in 2016 and is developing a pipeline of sustained pharmaceutical therapies, surgical devices, and implantable biosensors intended to treat glaucoma progression, corneal disorders such as keratoconus, dry eye and refractive vision correction, and retinal diseases such as neovascular age-related macular degeneration, diabetic macular edema and retinal vein occlusion.

On November 21, 2019, the Company acquired Avedro, Inc. (Avedro), a hybrid ophthalmic pharmaceutical and medical technology company focused on developing therapies designed to treat corneal diseases and disorders and correct refractive conditions, in a stock-for-stock transaction (Avedro Merger). Avedro developed novel bio-activated drug formulations used in combination with proprietary systems for the treatment of progressive keratoconus and corneal ectasia following refractive surgery. The therapy is the first and only minimally invasive anterior segment product offering approved by the FDA shown to halt the progression of keratoconus.

The accompanying consolidated financial statements include the accounts of Glaukos and its wholly-owned subsidiaries. All significant intercompany balances and transactions among the consolidated entities have been eliminated in consolidation.

Recent Developments

2022 U.S. reimbursement rates

Attillaps License Agreement

On September 20, 2021, the Company announced that it had entered into a licensing agreement (Attillaps License Agreement) with Attillaps Holdings, Inc. (Attillaps) under which Attillaps granted the Company a global exclusive license to Attillaps’ proprietary library of investigational pharmaceutical compounds that target the eradication of Demodex mites, which are the root cause of Demodex blepharitis and often associated with meibomian gland dysfunction and related ophthalmic diseases. Under the Attillaps Licensing Agreement, the Company has the exclusive global right to research, develop, manufacture and commercialize products using certain acetylcholinesterase inhibitors for the treatment of ophthalmic diseases caused by Demodex mites. The Company paid $5.0 million upon the signing of the Attillaps License Agreement, which is included in in-process research and development within the consolidated statements of operations, as management determined there were no alternative future uses for the technology acquired. The Company will have ongoing milestone and royalty payment obligations depending on the success of the development, approval and commercialization of the compounds.

Settlement of Patent Litigation

On September 14, 2021, the Company entered into a settlement agreement (Settlement Agreement) with

Table of Contents

Ivantis, Inc. (Ivantis), pursuant to which the Company and Ivantis agreed to terminate the patent infringement lawsuit we had filed against Ivantis on April 14, 2018 in the U.S. District Court for the Central District of California, Southern Division (the Lawsuit). In the Lawsuit, the Company alleged that Ivantis’ Hydrus® Microstent device infringes the Company’s U.S. Patent Nos. 6,626,858 and 9,827,143. Pursuant to the terms of the Settlement Agreement, Ivantis was to pay the Company a cash payment of $60.0 million, $30.0 million of which was paid to the Company during the year ended December 31, 2021, and $30.0 million of which will be paid by the earlier of (i) December 31, 2022, or (ii) 30 days after the consummation of the sale to a third party of all or substantially all of Ivantis’ equity or assets such that the third-party controls Ivantis. The $30.0 million cash payment received during the year ended December 31, 2021 is included in litigation-related settlement as a reduction of operating expenses on the consolidated statements of operations. See Note 15, Subsequent Events for details regarding payment by Ivantis of their second $30.0 million payment to the Company.

Additionally, Ivantis will make quarterly royalty payments to the Company in the amount of 10% of Ivantis’ Hydrus Microstent U.S. sales and any international sales supplied out of the U.S. beginning in the fourth quarter of 2021 through April 26, 2025, subject to a per-unit minimum payment. The Company and Ivantis have dismissed with prejudice all of their respective claims against the other in the Lawsuit, which was scheduled for trial beginning in September 2021, and in related lawsuits in other forums and jurisdictions. The parties also have agreed to mutual licenses and covenants not to sue the other party for patent infringement relating to Ivantis’ Hydrus Microstent or the Company’s micro-stent devices.

Santen License Agreement

On May 18, 2021, the Company announced that it entered into a new development and commercialization license agreement with Santen Pharmaceutical Co., Ltd. (Santen) for the PreserFlo MicroShunt superseding the previous collaboration and distribution agreements between the two parties. Under the new agreement, the Company obtains exclusive commercialization rights for the MicroShunt in the United States, Australia, New Zealand, Canada, Brazil, Mexico and the remainder of Latin America. The new agreement also provides the Company with full control over all development activities for the MicroShunt in these same territories, including all clinical development and regulatory affairs activities in the U.S. following a transition period. Santen submitted a premarket approval (PMA) application to the U.S. Food and Drug Administration (FDA) in June 2020 and discussions with the FDA remain ongoing. The Company did not make any payment in connection with the execution of the license agreement; however, should the Company be successful in obtaining regulatory approval for the PreserFlo MicroShunt, it would be required to pay Santen a milestone payment, followed by royalties and other potential future milestones depending on the success of the commercialization of the product.

Intratus License Amendment

On April 14, 2021, the Company announced that it had entered into an amended licensing agreement with Intratus, Inc. (Intratus) under which Intratus granted the Company a global exclusive license to research, develop, manufacture and commercialize Intratus’ patented, non-invasive drug delivery platform for application in the treatment of presbyopia. The addition of presbyopia expands upon the existing agreement between the Company and Intratus announced on July 22, 2019. The amendment includes a mechanism to further expand the existing agreement to other indications, applying the active pharmaceutical ingredients being advanced by the Company in glaucoma, corneal disorders and presbyopia to new ophthalmic fields. The Company paid $5.0 million upon the signing of the Intratus License Agreement, which is included in in-process research and development within the consolidated statements of operations, as management determined there were no alternative future uses for the technology acquired.

For the year ended December 31, 2021, the Company incurred net losses of $49.6 million and cash from operations provided $24.7 million and, as of December 31, 2021, the Company had an accumulated deficit of $365.2 million. For the year ended December 31, 2020, the Company incurred a net loss of $120.3 million, and $23.0 million of cash was used by operating activities. The Company has made and expects to continue to make significant investments in our global sales force, marketing programs, research and development activities, clinical studies and general and administrative infrastructure. FDA-approved IDE and IND studies and new product development programs in our industry are expensive. The Company also expects to incur additional construction costs related to its new facility in Aliso Viejo, California.

The Company’s 2.75% convertible notes due 2027 (Convertible Notes) may be converted at the option of the holders at the times and under the circumstances and at the conversion rate described in Note 8, Convertible Senior Notes. As of December 31, 2021, none of the conditions allowing holders of the Convertible Notes to convert had been met.

The Company plans to fund its operations, capital funding and other liquidity needs using existing cash and investments and, to the extent available, cash generated from commercial operations. The Company’s existing cash and investments include, in part, the net proceeds from the Convertible Notes issued in June 2020 (after payment for the related capped call transactions), and the $30.0 million paid to the Company by Ivantis in September 2021 pursuant to the terms of the Settlement Agreement, which the Company is using for working capital and general corporate purposes.

Although the Company has been profitable for certain periods in its operating history, there can be no assurance that it will be profitable or generate cash from operations. The Company may seek to obtain additional financing in the future through other debt or equity financings. There can be no assurance that the Company will be able to obtain additional financing on terms acceptable, or at all. As of December 31, 2021, the Company had cash, cash equivalents, restricted cash and short-term investments totaling $423.5 million and net working capital of $422.8 million. The Company has performed an analysis and concluded substantial doubt does not exist with respect to the Company being able to continue as a going concern through one year from the date of issuance of the consolidated financial statements for the year ended December 31, 2021.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).

Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates and assumptions. Management considers many factors in selecting appropriate financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. The most significant estimates in the accompanying consolidated financial statements for the year ended December 31, 2021 relate to revenue recognition, the incremental borrowing rate related to the Company’s leased assets, and stock-based compensation expense. For the years ended December 31, 2020 and December 31, 2019, in addition to the aforementioned estimates, the fair value of the liability component of the Company’s Convertible Notes and the valuation of certain intangible assets related to the Company’s Avedro Merger were significant estimates.Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, this process may result in actual results differing materially from those estimated amounts used in the preparation of the consolidated financial statements.

The Company’s consolidated financial statements as of and for the year ended December 31, 2021 reflect the Company’s estimates of the impact of the ongoing COVID-19 pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are uncertain, including the duration and severity of the COVID-19 outbreak, the severity and transmission rates of new and more contagious/and or vaccine-resistant variants of COVID-19, and the actions taken to contain it or treat COVID-19, including the availability, distribution, rate

Table of Contents

of public acceptance and efficacy of vaccines for COVID-19, as well as the economic impact on local, regional, national and international customers and markets. As a result, there may be changes to the Company’s estimates regarding the impact of COVID-19 in future periods.

Segments

The Company has one business activity and operates as one operating segment: the development and commercialization of ophthalmic therapies designed to treat glaucoma, corneal disorders and retinal diseases. The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company’s chief operating decision-maker (CODM), its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance.

Cash, Cash Equivalents, Restricted Cash and Short-term Investments

The Company invests its excess cash in marketable securities, including U.S. government agency bonds, U.S. government bonds, bank certificates of deposit, commercial paper, municipal bonds, corporate notes and asset-backed securities. For financial reporting purposes, liquid investment instruments purchased with an original maturity of three months or less are considered to be cash equivalents. Cash and cash equivalents are recorded at face value or cost, which approximates fair market value. The Company maintains cash balances in excess of amounts insured by the Federal Deposit Insurance Commission. Investments are stated at fair value as determined by quoted market prices. Investments are considered available for sale and, accordingly, unrealized gains and losses are included in accumulated other comprehensive (loss) income within stockholders’ equity.

The Company’s entire investment portfolio, except for restricted cash, is considered to be available for use in current operations and, accordingly, all such investments are stated at fair value using quoted market prices and classified as current assets, although the stated maturity of individual investments may be one year or more beyond the balance sheet date. The Company did not have any trading securities or restricted investments at December 31, 2021 or December 31, 2020.

Realized gains and losses and declines in value, if any, judged to be other-than-temporary on available for sale securities, are reported in other (expense) income, net. When securities are sold, any associated unrealized gain or loss previously reported as a separate component of stockholders’ equity is reclassified out of stockholders’ equity and recorded in the statements of operations in the period sold using the specific identification method. Accrued interest and dividends from investments are included in other (expense) income, net. The Company periodically reviews its available for sale securities for other than temporary declines in fair value below the cost basis, and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that equate to the amount reported in the consolidated statement of cash flows as of December 31, 2021, December 31, 2020 and December 31, 2019 (in thousands):

Concentration of Credit Risk and Significant Customers

Financial instruments, which potentially subject the Company to significant concentration of credit risk, consist primarily of cash, cash equivalents, short-term investments and accounts receivable. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Additionally, the Company has established guidelines regarding investment instruments and their maturities

Table of Contents

which are designed to maintain preservation of principal and liquidity. The Company believes that the concentration of credit risk in its accounts receivable is mitigated by its credit evaluation process, relatively short collection terms and the level of credit worthiness of its customers. During the years ended 2021, 2020 and 2019, none of the Company’s customers accounted for more than 10% of revenues.

Accounts Receivable

The Company sells its products directly to ambulatory surgery centers, hospitals, and physician private practices, with distributors being used in certain international locations where the Company does not have a direct commercial presence and the Company is exposed to credit losses primarily through sales of its products.

The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and periodic evaluation of customers’ receivables balances. Management estimates the adequacy of the allowance by using relevant available information, from internal and external sources, relating to past events, current conditions and forecasts. Historical credit loss experience provides the basis for estimation of expected credit losses and are adjusted as necessary using the relevant information available. The allowance for credit losses is measured on a collective basis when similar risk characteristic exists. The Company has identified one portfolio segment based on evaluation of the following risk characteristics: geographic regions, product lines, default rates and customer specific factors.

Additionally, specific allowance amounts may be established to record the appropriate provision for customers that have a higher probability of non-payment. The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. The Company’s allowance for credit losses represents management’s estimate of current expected credit losses and totaled approximately $1.4 million and $1.7 million as of December 31, 2021 and December 31, 2020, respectively, and there were immaterial bad-debt write offs charged during the years ended December 31, 2021 and December 31, 2020.

As of December 31, 2021 and December 31, 2020 the Company evaluated the current and expected future economic and market conditions surrounding the COVID-19 pandemic as it relates to collectability of its accounts receivable and determined the estimate of expected credit losses was not materially impacted. The Company will continue to re-evaluate the estimate of credit losses related to COVID-19 in conjunction with its assessment of expected credit losses in subsequent quarters.

Additionally, no customers accounted for more than 10% of net accounts receivable as of December 31, 2021 or December 31, 2020.

Inventory

Inventory is valued at the lower of cost and net realizable value with cost being determined by the first-in, first-out method. Management evaluates inventory for excess quantities and obsolescence and records an allowance to reduce the carrying value of inventory as determined necessary.

Property and Equipment, Net

Property and equipment is recorded at cost. Depreciation of property and equipment is generally provided using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized over their estimated useful life or the related lease term, whichever is shorter. Maintenance and repairs are expensed as incurred.

All long lived assets are reviewed for impairment in value when changes in circumstances dictate, based upon undiscounted future operating cash flows, and appropriate losses are recognized and reflected in current earnings to the extent the carrying amount of an asset exceeds its estimated fair value, determined by the use of appraisals, discounted cash flow analyses or comparable fair values of similar assets. The Company did not record any impairment charges for the year ended December 31, 2021 and December 31, 2020; however the Company recorded impairment charges of $0.4 million during the year ended December 31, 2019.

Table of Contents

Intangible Assets

Intangible assets primarily consist of developed technology, customer relationships, and IPR&D assets related to the Avedro Merger.

Intangible assets with finite-lives include developed technology, customer relationships and the buyout of a royalty payment obligation, which are amortized on a straight-line basis over their estimated useful lives, which range from five to eleven years. The Company reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. When such an event occurs, management determines whether there has been impairment by comparing the anticipated undiscounted future net cash flows to the related asset group’s carrying value. If the affected intangible assets are not recoverable, management estimates the fair value of the assets and would record an impairment loss if the carrying value of the assets exceeds the fair value.

Indefinite-lived intangible assets are comprised of IPR&D assets and are not amortized, but instead tested for impairment until the successful completion and commercialization, or abandonment, of the associated research and development efforts, at which point the IPR&D assets are either amortized over their estimated useful lives, or written-off immediately, as the case may be.

Refer to Note 6, Intangible Assets and Goodwill for more information on the Company’s intangible assets.

Goodwill

Goodwill totaled $66.1 million at December 31, 2021 and December 31, 2020. Goodwill is recorded as a result of business combinations. If the Company determines the carrying value of a reporting unit exceeds its fair value, an impairment charge would be recognized and should not exceed the total amount of goodwill allocated to that reporting unit. The Company tests for impairment annually, on October 1 and in addition to that test, regularly assesses if an event has occurred which would require interim impairment testing. The Company considered the current and expected future economic and market conditions surrounding COVID-19 pandemic and during the year did not identify an indication of goodwill impairment due that event. The Company’s annual impairment test did not result in any impairment, and the Company has not identified any indicators of impairment through December 31, 2021.

Refer to Note 6, Intangible Assets and Goodwill for more information on the Company’s goodwill.

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, accounts payable, and accrued liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments.

The valuation of assets and liabilities is subject to fair value measurements using a three-tiered approach and fair value measurements are classified and disclosed by the Company in one of the following three categories:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Table of Contents

Leases

The Company determines if an arrangement is a lease at inception. As a lessee, right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company estimates the incremental borrowing rate based on its debt, prevailing financial market conditions, peer company credit analyses, and management judgment. Operating lease right-of-use assets also include any lease payments made at or before lease commencement and exclude any lease incentives received. The lease terms used to calculate the right-of-use asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as amortization expense on right-of-use lease assets and interest expense using the accelerated interest method of recognition.

Revenue Recognition

The Company derives its revenue from sales of its products in the United States and internationally. Customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with distributors being used in certain international locations where the Company does not have a direct commercial presence.

The Company concluded that one performance obligation exists for the majority of its contracts with customers which is to deliver products in accordance with the Company’s normal delivery times. Revenue is recognized when this performance obligation is satisfied, which is the point in time when the Company considers control of a product to have transferred to the customer. Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for those products or services. The Company has determined the transaction price to be the invoice price, net of adjustments, which includes estimates of variable consideration for product returns.

The Company only recognizes revenue when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods it transfers to the customer. This requires management to perform an assessment related to the probability of collecting the consideration. The assessment can contain judgment when it is performed for customers with declining credit conditions or those with no history or a limited history of product sales with the Company.

The Company offers volume-based rebate agreements to certain customers and, in these instances, the Company provides a rebate (in the form of a credit memo) at the contract’s conclusion, if earned by the customer. In such cases, the transaction price is allocated between the Company’s delivery of product and the issuance of a rebate at the contract’s conclusion for the customer to utilize on prospective purchases. The performance obligation to issue a customer’s rebate, if earned, is transferred over time and the Company’s method of measuring progress is the output method, whereby the progress is measured by the estimated rebate earned to date over the total rebate estimated to be earned over the contract period. The provision for volume-based rebates is estimated based on customers' contracted rebate programs and the customers’ projected sales levels. The Company periodically monitors its customer rebate programs to ensure the rebate allowance is fairly stated. The Company’s rebate allowance is included in accrued liabilities in the consolidated balance sheets and estimated rebates accrued were not material during the periods presented.

Additionally, the Company has a performance obligation related to certain customers’ right to a future discount on single dose pharmaceutical purchases in the U.S., and that performance obligation is expected to be recognized when the customer elects to utilize the discount, which is generally within one year. Additionally, the Company has a performance obligation related to its extended warranty agreements with customers related to its KXL systems.

Customers are not granted specific rights of return; however, the Company may permit returns of certain products from customers if such product is returned in a timely manner and in good condition. The Company generally provides a warranty on its products for one year from the date of shipment, and offers an extended warranty for its KXL

Table of Contents

systems. Any product found to be defective or out of specification will be replaced or serviced at no charge during the warranty period. Estimated allowances for sales returns and warranty replacements are recorded at the time of sale of the product and are estimated based upon the historical patterns of product returns matched against sales, and an evaluation of specific factors that may increase the risk of product returns. Product returns and warranty replacements to date have been consistent with amounts reserved or accrued and have not been significant. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates which would affect net product revenue and earnings in the period such variances become known.

Convertible Senior Notes

See Recently Adopted Accounting Pronouncements below for the Company’s accounting for its Convertible Senior Notes.

Shipping and Handling Costs

All shipping and handling costs are expensed as incurred and are charged to general and administrative expense. Charges to customers for shipping and handling are credited to general and administrative expense.

Advertising Costs

All advertising costs are expensed as incurred. Advertising costs incurred during the years ended December 31, 2021, December 31, 2020 and December 31, 2019 were approximately $1.2 million, $1.6 million and $2.5 million, respectively.

Income Taxes

Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities at the applicable tax rates, along with NOL and tax credit carryovers. The Company records a valuation allowance against a portion of deferred tax assets to reduce the net carrying value to an amount that it believes is more likely than not to be realized. Management has considered estimated taxable income and ongoing prudent and feasible tax planning strategies in assessing the amount of the valuation allowance. Based upon the weight of available evidence, which includes the Company’s historical operating performance and limited potential to utilize tax credit carryforwards, the Company has determined that a portion of its deferred tax assets should be offset by a valuation allowance. When the Company establishes or reduces the valuation allowance against its deferred tax assets, its provision for income taxes increases or decreases, respectively, in the period such determination is made.

The Company is required to file federal and state income tax returns in the United States and various other state jurisdictions. The Company also files income tax returns in the foreign countries in which its subsidiaries operate. The preparation of these income tax returns requires the Company to interpret the applicable tax laws and regulations in effect in such jurisdictions, which could affect the amount of tax paid.

Additionally, the Company follows an accounting standard addressing the accounting for uncertainty in income taxes that prescribes rules for recognition, measurement, and classification in the consolidated financial statements of tax positions taken or expected to be taken in a tax return.

Research and Development Expenses

Major components of research and development expense include personnel costs, preclinical studies, clinical trials and related clinical product manufacturing, materials and supplies, and fees paid to consultants. Research and development costs are expensed as goods are received or services are rendered. Costs to acquire technologies to be used in research and development that have not reached technological feasibility and have no alternative future use are also expensed as incurred.

Table of Contents

At each financial reporting date, the Company accrues the estimated unpaid costs of clinical study activities performed during a period by third party clinical sites with whom the Company has agreements that provide for fees based upon the quantities of subjects enrolled and clinical evaluation visits that occur over the life of the study. The cost estimates are determined based upon a review of the agreements and data collected by internal and external clinical personnel as to the status of enrollment and subject visits, and are based upon the facts and circumstances known to the Company at each financial reporting date. If the actual performance of activities varies from the assumptions used in the cost estimates, the accruals are adjusted accordingly. There have been no material adjustments to the Company’s prior period accrued estimates for clinical trial activities through December 31, 2021.

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based awards granted to employees and nonemployees, including members of its board of directors.

The fair value of stock option awards is estimated at the grant date using the Black-Scholes option pricing model, and the portion that is ultimately expected to vest is recognized as compensation cost over the requisite service period using the straight-line method. The determination of the fair value-based measurement of stock options on the date of grant using an option pricing model is affected by the determination of the fair value of the underlying stock as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Company’s stock price volatility over the expected term of the grants, and actual and projected stock option exercise behaviors. In the future, as additional empirical evidence regarding these estimates becomes available, the Company may change or refine its approach of deriving them, and these changes could impact the fair value-based measurement of stock options granted in the future. Changes in the fair value-based measurement of stock awards could materially impact the Company’s operating results.

The fair value of restricted stock unit (RSU) awards made to employees and nonemployees is equal to the closing market price of the Company’s common stock on the grant date.

Software Costs

The Company capitalizes certain costs when it is determined that it is probable that the project will be completed, the software will be used to perform the function intended, and the preliminary project stage is completed. These capitalized costs are included in property and equipment, net within the consolidated balance sheets.

Comprehensive (Loss) Income

All components of comprehensive (loss) income, including net (loss) income, are reported in the consolidated financial statements in the period in which they are recognized. Comprehensive (loss) income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on marketable securities and foreign currency translation adjustments.

Net (Loss) Income per Share

Basic net (loss) income per share is calculated by dividing the net (loss) income by the weighted average number of common shares that were outstanding for the period, without consideration for common stock equivalents.

For periods when the Company realizes a net loss, no common stock equivalents are included in the calculation of weighted average number of dilutive common stock equivalents as the effect of applying the treasury stock method is considered anti-dilutive.

For periods when the Company realizes net income, diluted net income per share is calculated by dividing the net income by the weighted average number of common shares plus the sum of the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury stock method. Common stock equivalents are comprised of stock options, outstanding and unvested RSUs under the Company’s incentive compensation plans and shares issuable under the Company’s Employee Stock Purchase Plan (ESPP) and, beginning January 1, 2021, shares convertible pursuant to the Convertible Notes.

Recently Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-06, which simplifies accounting for convertible instruments. The embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under ASU 2020-06, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method to compute diluted earnings per share to be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Adoption of the standard requires using either a modified retrospective or a full retrospective approach. Effective January 1, 2021, the Company early adopted ASU 2020-06 using the modified retrospective adoption approach. The cumulative effect of the change was recognized as an adjustment to the opening balance of retained earnings at the date of adoption. The comparative prior year information has not been restated and continues to be presented according to accounting standards in effect for those periods.

The adoption of ASU 2020-06 resulted in an increase to accumulated deficit of $5.5 million, a decrease to additional paid-in capital of $81.6 million, a decrease in the deferred tax liability of $2.2 million and an increase to convertible notes, net of $89.2 million. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. Lastly, the Company derecognized deferred income taxes associated with the Convertible Notes and adjusted the deferred tax liability

associated with the embedded conversion feature and corresponding change in the valuation allowance.
