NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

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 pharmaceutical and medical technology company focused on developing novel dropless platform therapies and commercializing associated products for the treatment of glaucoma, corneal disorders, and retinal diseases. The Company first developed Micro-Invasive Glaucoma Surgery (MIGS) as an alternative to the traditional glaucoma treatment paradigm, launching its first MIGS device commercially in 2012. The Company also offers commercially a proprietary bio-activated pharmaceutical therapy for the treatment of a rare corneal disorder, keratoconus, that was approved by the United States (U.S.) Food and Drug Administration (FDA) in 2016. The Company received FDA approval in December 2023 of its first procedural pharmaceutical product, the iDose TR, and began commercializing the product in a controlled manner in February 2024. The Company is developing a portfolio of 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, diabetic macular edema and retinal vein occlusion.

The accompanying condensed consolidated financial statements include the accounts of Glaukos and its wholly-owned subsidiaries. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. All intercompany balances and transactions among the consolidated entities have been eliminated in consolidation.

Basis of presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted (GAAP) in the U.S. for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X.

As permitted by Form 10-Q and Article 10 of Regulation S-X, under those rules, certain footnotes and other financial information that are normally required by GAAP have been condensed or omitted. The unaudited interim financial statements have been prepared on a basis consistent with the audited financial statements. In the opinion of management, the unaudited interim financial statements reflect all adjustments necessary for the fair presentation of the Company’s financial information contained herein. All such adjustments are of a normal and recurring nature. The condensed consolidated balance sheet as of December 31, 2023 has been derived from audited financial statements at that date, but excludes disclosures required by GAAP for complete financial statements. These interim financial statements do not include all disclosures required by GAAP and should be read in conjunction with the Company’s financial statements and accompanying notes for the fiscal year ended December 31, 2023, which are contained in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (SEC) on February 23, 2024. The Company’s results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other interim period.

Recent developments

On March 7, 2024, the Company issued $5.0 million of its common stock and paid approximately $5.1 million in cash in connection with the acquisition of 100% of the outstanding equity interests in a clinical stage biopharma company (the Seller) focused on developing novel therapeutics for rare ophthalmic diseases, including all related patents and patent applications, technology and know-how. The Company accounted for the transaction as an asset acquisition as the set of acquired assets did not constitute a business, and the acquisition costs are recorded within acquired in-process research and development on the condensed consolidated statement of operations. Under the terms of the agreement, if these proprietary technologies are commercialized, the Company may have to make potential payments of up to $51.0 million upon the achievement of certain event-based development milestones, potential payments of up to $150.0 million upon the achievement of certain commercial sales-based milestones should annual net sales of a licensed product eventually exceed various levels, and up to a low double digit royalty on net sales. Furthermore, because the first

Table of Contents

two development milestones are payable in either cash or Company shares at the Company’s sole discretion, the Company has accrued a liability in the amount of $1.4 million related to these two milestones, which is classified as other liabilities within the condensed consolidated balance sheets, as the contingent consideration is not expected to be paid within the next twelve months. See also Note 4, Fair Value Measurements for additional details regarding this contingent consideration.

Effective March 17, 2023, the Company entered into a sales agreement (Sales Agreement) with Celanese Canada ULC (Celanese) under which Celanese will make available and supply to the Company certain raw materials used to create a nanoporous membrane utilized in the iDose TR, and authorized the Company to reference its Drug Master File (DMF) with respect to such raw materials, which is required for the Company to commercialize iDose TR. The term of the Sales Agreement is four years after the iDose TR launch date in February 2024. In exchange for the ability to obtain future raw materials and the rights related to the DMF, the Company is subject to minimum compensation payments over four years of $6.3 million and potential additional royalties based on a percentage of sales of the iDose TR product. The Company recognized an intangible asset related to the minimum compensation payments at fair value of $5.2 million upon the date of acquisition, which was determined to be the iDose TR launch date. The $5.2 million is included in Intangible Assets, Net on the condensed consolidated balance sheets and will be amortized to cost of sales over its useful life of four years, which is the initial term of the Sales Agreement. A member of the Celanese board of directors also sits on the board of directors of the Company.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates and assumptions used in the preparation of the accompanying condensed consolidated financial statements.

The Company’s condensed consolidated financial statements as of and for the three months ended March 31, 2024 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation, supply shortages or delays, changes in supply and demand, foreign exchange rate fluctuations and other conditions which have led to disruptions in commerce and pricing stability. While the specific impact of these factors is not readily determinable, in the past three months the Company has not experienced a material financial statement impact or business disruptions as a result of these negative macroeconomic and geopolitical trends. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of March 31, 2024.

Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the condensed consolidated balance sheets that equate to the amount reported in the condensed consolidated statements of cash flows as of the beginning and end of the three months ended March 31, 2024 (in thousands):


	March 31,		December 31,
	2024		2023
Cash and cash equivalents	$	42,495	$	93,467
Restricted cash		5,856		5,856
Cash, cash equivalents and restricted cash	$	48,351	$	99,323

The Company’s cash and cash equivalents include cash in readily available checking and money market accounts, as well as certificates of deposit. The Company maintains balances of cash and cash equivalents at one or more financial institutions that are in excess of federally insured limits.

Table of Contents

Recently Adopted Accounting Pronouncements

The Company has not adopted any recent accounting pronouncements that had a material impact on its condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid by jurisdiction. The ASU is effective for public business entities’ annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance on its condensed consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segments Disclosures. While ASU 2023-07 requires incremental disclosures, it does not change how an entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine reportable segments. This ASU is effective for all public business entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Entities must adopt the changes to the segment reporting guidance on a retrospective basis. The Company is currently evaluating the impact of adopting this guidance on its condensed consolidated financial statements. Early adoption is permitted; however, the Company is not early adopting the standard.

At each reporting date, the Company performs an evaluation of impairment to determine if any unrealized losses are the result of credit losses. Impairment is assessed at the individual security level. Factors considered in determining whether a loss resulted from a credit loss or other factors include the Company’s intent and ability to hold the investment until the recovery of its amortized cost basis, the extent to which the fair value is less than the amortized

Table of Contents

cost basis, the length of time and extent to which fair value has been less than the cost basis, the financial condition of the issuer, any historical failure of the issuer to make scheduled interest or principal payments, any changes to the rating of the security by a rating agency, any adverse legal or regulatory events affecting the issuer or issuer’s industry, and any significant deterioration in economic conditions.

The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest expense in the condensed consolidated statements of operations through an allowance for credit losses. Unrealized gains and losses that are not credit-related are included in accumulated other comprehensive loss. Unrealized losses on available-for-sale debt securities as of March 31, 2024 and December 31, 2023 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Further, the Company does not intend to sell these investments prior to maturity and it is not more likely than not that the Company will be required to sell these investments before recovery of their amortized cost basis. Accordingly, the Company did not record an allowance for credit losses with these investments as of March 31, 2024 and December 31, 2023.

Note 4. Fair Value Measurements

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

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).

The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023 indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands):

Money market funds are highly-liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy.

U.S. government agency bonds, U.S. treasury securities, bank certificates of deposit, commercial paper, municipal bonds, corporate notes and asset-backed securities are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each measurement date. Pursuant to the Company’s deferred compensation plan (the Deferred Compensation Plan), the Company has also established a rabbi trust that serves as an investment to shadow the Deferred Compensation Plan liability. The investments of the rabbi trust and Deferred Compensation Plan liability consist of company-owned life insurance policies (COLIs) and the pricing on these investments can be independently evaluated. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from third party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy.

The Company recorded a contingent consideration liability upon the asset acquisition, as described in Recent Developments within Note 1, Organization and Basis of Presentation above. The contingent consideration is measured at fair value and is based on significant inputs not observable in the market which includes the probability and timing of achieving certain future milestones, and to a lesser extent, an applicable discount rate and Glaukos’ credit rating. This represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions the Company believes a market participant would make. The Company assesses these estimates on an ongoing basis as it obtains additional data impacting the assumptions. Changes in the fair value of contingent consideration related to updated assumptions and estimates are recognized within the condensed consolidated statements of operations.

Table of Contents

There were no transfers between levels within the fair value hierarchy during the periods presented.

The Company did not have any assets or liabilities measured at fair value on a recurring basis within Level 3 fair value measurements as of December 31, 2023.

Convertible Senior Notes

As of March 31, 2024 and December 31, 2023, the fair value of the Company’s 2.75% convertible notes due 2027 (Convertible Notes) was $514.6 million and $444.0 million, respectively. The fair value was determined on the basis of the market prices observable for similar instruments and is considered Level 2 in the fair value hierarchy. See Note 9, Convertible Senior Notes for additional information.

Note 5. Leases

The Company has operating and finance leases for facilities and certain equipment. Leases with an initial term of 12 months or less are expensed and not recorded on the condensed consolidated balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company’s leases have non-cancelable lease terms of approximately one year to thirteen years, some of which include options to extend the leases for up to ten years. The exercise of lease renewal options is at the Company’s sole discretion. In certain of the Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for common area maintenance, landlord incentives and/or inflation.

The Company’s office building lease in Aliso Viejo, California (Aliso Facility) is one property containing three existing office buildings, comprising approximately 160,000 rentable square feet of space, which was accounted for as a finance lease. The term of the Aliso Facility commenced on April 1, 2019 for expense recognition and continues for thirteen years. The lease agreement contains an option to extend the lease for two additional five year periods at market rates.

The Company also leases two adjacent buildings, two office suites and a warehouse located in San Clemente, California and a facility in Burlington, Massachusetts. The total leased square footage of the San Clemente facilities equals approximately 120,000 and the two most significant leases expire on May 31, 2030. Each of these two leases contain an option to extend the lease for one additional five-year period at market rates. The total leased square footage of the Burlington facility is approximately 60,000 square feet, and the lease expires on July 31, 2033. The Burlington facility lease contains an option to extend the lease for one additional five-year period at market rates.

The Company’s remaining foreign subsidiaries’ leased office space totals less than 15,000 square feet.

The following table presents the maturity of the Company’s operating and finance lease liabilities within the condensed consolidated balance sheets:


Maturity of Lease Liabilities	Operating		Finance

Note 6. Intangible Assets and Goodwill

Intangible assets

For the three months ended March 31, 2024 and March 31, 2023, amortization expense related to the Company’s finite-lived intangible assets was approximately $5.5 million and $0.7 million, recorded in cost of sales and selling, general and administrative expenses, respectively, in the condensed consolidated statements of operations.

The Company evaluated its indefinite-lived intangible assets for impairment and concluded there were no indicators of impairment as of March 31, 2024.

Goodwill

The assessment of goodwill by reporting unit is performed annually, in the fourth quarter, or more frequently if events or circumstances indicate the carrying value may no longer be recoverable and that an impairment loss may have occurred. The Company considered the current and expected future economic and market conditions and its impact on the Company’s reporting unit. Based on interim assessments, the Company did not identify any “triggering” events which would indicate an impairment of goodwill is more likely than not as of March 31, 2024.

The following table presents the composition of the Company’s intangible assets and goodwill (in thousands):

Note 7. Revenue from Contracts with Customers

The Company’s net sales are generated primarily from sales of its iStent family of products, Photrexa and associated drug formulations, KXL systems and royalty income. The Company’s customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with third party distributors being used in certain international locations where the Company currently 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 that reduce revenue, which included estimates of commercial and governmental rebates owed, variable consideration for product returns and warranty replacements and other discounts and incentives that reduce revenue. Our process for estimating reserves established for these variable consideration components does not differ materially from historical practices. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, may be subject to constraint and is included in the net sales price only to the extent that it is probable that a significant reversal of the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts may ultimately differ from our estimates. If actual results vary, we adjust these estimates, which could have an effect on earnings in the period of adjustment.

Revenue is recognized at an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services, and substantially all of the Company’s net sales for the three months ended March 31, 2024 are considered revenue from contracts with customers.

Disaggregation of Revenue

The Company’s revenues disaggregated by product category and geography for the three months ended March 31, 2024 and March 31, 2023 were as follows (in thousands):

Contract Balances

Contract Assets

Amounts are recorded as accounts receivable when the Company’s right to consideration becomes unconditional. Payment terms on invoiced amounts are typically 30 days for glaucoma and corneal health products, though extended payment terms may be offered. However, the Company does not consider any significant financing components in customer contracts given the expected time between transfer of the promised products and the payment of the associated consideration is less than one year. As of March 31, 2024 and December 31, 2023, substantially all amounts included in accounts receivable, net on the condensed consolidated balance sheets are related to contracts with customers.

Note 9. Convertible Senior Notes

The Company accounts for its convertible senior notes as a single unit of accounting, a liability, because the Company concluded that there were no material conversion features that require bifurcation as a derivative and its convertible debt instruments were not issued at a substantial premium.

In June 2020, the Company issued $287.5 million in aggregate principal amount of Convertible Notes pursuant to an indenture dated June 11, 2020, between the Company and Wells Fargo Bank, National Association, as trustee (the Indenture), in a private offering to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended. The Convertible Notes are senior unsecured obligations of the Company and bear interest at a rate of 2.75% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2020. The Convertible Notes will mature on June 15, 2027, unless earlier converted, redeemed or repurchased in accordance with their terms. In connection with issuing the Convertible Notes, the Company received $242.2 million in proceeds, after deducting fees and offering expenses and paying the cost of the capped call transactions described below.

The Convertible Notes may be converted at the option of the holders at any time prior to the close of business on the business day immediately preceding March 15, 2027, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ended on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of $56.10 on each applicable trading day; (2) during the five business day period immediately after any ten consecutive trading day period (the Measurement Period) in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the Measurement Period was less than 98% of the product of (i) the last reported sale price of the Company’s common stock and (ii) the conversion rate in effect on each such trading day; (3) with respect to any Convertible Notes the Company calls for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date, even if the Convertible Notes are not otherwise convertible at such time; or (4) upon the occurrence of specified corporate events. On or after March 15, 2027, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Convertible Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. Upon conversion, calculated based on the per share volume-weighted average price for each of the 30 consecutive trading days during the observation period (as more fully described in the Indenture), the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture.

As of March 31, 2024, one of the conditions allowing holders of the Convertible Notes to convert had been met. The trading price of the Company’s common stock remained above 130% of the applicable $56.10 conversion price for at least 20 trading days during the 30 consecutive trading-day period ending on, and including, March 31, 2024 resulting

in the right of holders of the Convertible Notes to convert their Convertible Notes beginning April 1, 2024 through June 28, 2024 (the last business day of the quarter ending June 30, 2024).

Interest expense relating to the Convertible Notes in the condensed consolidated statements of operations for the three months ended March 31, 2024 and March 31, 2023 is summarized as follows (in thousands):

Total interest expense	$	2,320	$	2,320

The effective interest rate on the Convertible Notes for the three months ended March 31, 2024 and March 31, 2023 was 3.2%.

As of March 31, 2024 and December 31, 2023, the Convertible Notes on the condensed consolidated balance sheets represented the carrying amount of the Convertible Notes, net of unamortized debt issuance costs, which are summarized as follows (in thousands):



	As of		As of

Less: Unamortized debt issuance costs		(4,383)		(4,727)
Carrying amount of Convertible Notes	$	283,117	$	282,773

Capped Call Transactions

In connection with the offering of the Convertible Notes, in June 2020 the Company entered into privately negotiated capped call transactions with certain financial institutions (the Option Counterparties) and used an aggregate $35.7 million of the net proceeds from the Convertible Notes to pay the cost of the capped call transactions. The capped call transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the Convertible Notes or at the Company’s election (subject to certain conditions) offset any cash payments the Company is required to make in excess of the aggregate principal amount of converted Convertible Notes, as the case may be, with such reduction or offset subject to a cap based on the cap price. The cap price of the capped call transactions is initially $86.30 per share, which represents a premium of 100% over the last reported sale price of the Company’s common stock on June 8, 2020, and is subject to certain adjustments under the terms of the capped call transactions. The capped calls have an initial strike price of approximately $56.10 per share, subject to certain adjustments, which corresponds to the conversion option strike price in the Convertible Notes. The capped call transactions cover, subject to customary adjustments, the number of shares of common stock initially underlying the Convertible Notes (or approximately 5.1 million shares of the Company’s common stock).

The capped call transactions are separate transactions that the Company entered into with the Option Counterparties, are not part of the terms of the Convertible Notes and will not change the holders’ rights under the Convertible Notes. As the capped call transactions meet certain accounting criteria, the cost of the capped call transactions of $35.7 million was recorded as a reduction in additional paid-in capital in the consolidated balance sheets and will not be remeasured to fair value as long as the accounting criteria continue to be met. As of March 31, 2024, the Company had not purchased any shares under the capped call transactions.

Note 10. Stock-Based Compensation

The following table summarizes the allocation of stock-based compensation related to stock options and RSUs in the accompanying condensed consolidated statements of operations (in thousands):


	Three Months Ended
	March 31,
	2024		2023
Cost of sales	$	726	$	408
Selling, general and administrative		7,271		6,910
Research and development		3,168		2,866
Total	$	11,165	$	10,184

At March 31, 2024, the total unamortized stock-based compensation expense was approximately $72.1 million, of which $10.3 million and $61.8 million was attributable to stock options and RSUs, respectively. The Company currently issues its annual stock option and RSU grants to eligible employees during the second quarter of each year.

Of the $10.3 million related to stock options, $10.0 million is attributable to time-based stock options and will be recognized over the time-based stock options’ remaining vesting terms of approximately 4.0 years (3.0 years on a weighted average basis). The remaining $0.3 million is attributable to performance-based options and will be recognized over the performance-based stock options’ remaining vesting terms of less than one year (0.8 years on a weighted average basis).

Of the $61.8 million related to RSUs, $61.5 million is attributable to time-based RSUs and will be recognized over the RSUs’ vesting terms of approximately 4.0 years (2.7 years on a weighted-average basis). The remaining $0.3 million is attributable to performance-based RSUs and will be recognized over the performance-based RSUs’ remaining vesting terms of less than one year (0.7 years on a weighted average basis).

The total stock-based compensation cost capitalized in inventory was not material for the three month periods ended March 31, 2024 and March 31, 2023.

Note 11. Income Taxes

The provision for income taxes is determined using an effective tax rate. For the three months ended March 31, 2024, the Company’s estimated effective tax rate of (0.93)% was lower than the U.S. federal statutory rate primarily due to the utilization of U.S. net operating loss (NOL) and generation of R&D tax credit carryforwards that are partially offset by a valuation allowance, as well as state and foreign income taxes. The effective tax rate may be subject to fluctuations during the year as new information is obtained that may affect the assumptions used to estimate the effective tax rate, including factors such as expected utilization of NOL carryforwards, changes in or the interpretation of tax laws in jurisdictions where the Company conducts business, expansion of the Company’s taxable presence in domestic and foreign markets, and the amount of valuation allowances against deferred tax assets. For each of the three months ended March 31, 2024 and March 31, 2023, the Company recorded a provision for income taxes of $0.4 million, which was primarily comprised of state and foreign income tax expense.

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 financial statements of tax positions taken or expected to be taken in a tax return. As of March 31, 2024 and December 31, 2023, the Company had gross unrecognized tax benefits of $33.7 million and $32.8 million, respectively.

Note 12. Commitments and Contingencies

Secured Letters of Credit

The Company has a letter of credit that is related to its Aliso Facility. The letter of credit is secured with an amount of cash held in a restricted account of approximately $5.6 million as of March 31, 2024 and December 31, 2023, respectively. Beginning as of the first day of the thirty-seventh month of the lease term (which occurred during 2022), and on each twelve-month anniversary thereafter, the letter of credit will be reduced by 20% until the letter of credit amount has been reduced to $2.0 million.

The discussion and analysis below contains forward-looking statements within the meaning of federal securities laws, and should be read in conjunction with the disclosures we make concerning risks and other factors that may affect our business and operating results. See “Note Regarding Forward-Looking Statements” preceding Part I, Item 1 in this Quarterly Report on Form 10-Q.

Overview

We are an ophthalmic pharmaceutical and medical technology company focused on developing novel, dropless platform therapies and commercializing associated products 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. We also offer commercially a proprietary bio-activated pharmaceutical therapy for the treatment of a rare corneal disorder, keratoconus, that was approved by the U.S. Food and Drug Administration (FDA) in 2016. We received FDA approval in December 2023 for our first procedural pharmaceutical product, the iDose TR, an intracameral procedural pharmaceutical therapy designed to continuously deliver 24/7 therapeutic levels of a proprietary formulation of travoprost inside the eye for extended periods of time, and we began commercializing iDose TR in a controlled manner in February 2024. We are developing a portfolio of platforms to support ongoing pharmaceutical and medical device innovations. Products and 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, diabetic macular edema, and retinal vein occlusion.

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.

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 for each of the three months ended March 31, 2024 and March 31, 2023 of $40.8 million $34.6 million, respectively. As of March 31, 2024, we had an accumulated deficit of $639.9 million.

Recent Developments

On March 7, 2024, we issued $5.0 million of our common stock and paid approximately $5.1 million in cash in connection with the acquisition of 100% of the outstanding equity interests in a clinical stage biopharma company (the Seller) focused on developing novel therapeutics for ophthalmic diseases, including all related patents and patent applications, technology and know-how. We accounted for the transaction as an asset acquisition as the set of acquired assets did not constitute a business, and the acquisition costs are recorded within acquired in-process research and

development on the condensed consolidated statement of operations. Under the terms of the agreement, if these proprietary technologies are commercialized, we may have to make potential payments of up to $51.0 million upon the achievement of certain event-based development milestones, potential payments of up to $150.0 million upon the achievement of certain commercial sales-based milestones should annual net sales of a licensed product eventually exceed various levels, and up to a low double digit royalty on net sales. Furthermore, because the first two development milestones are payable in either cash or the Company’s shares at our sole discretion, we have accrued $1.4 million related to these two milestones which is classified as an other liability within the condensed consolidated balance sheets, as the contingent consideration is not expected to be paid within the next twelve months.

Effective March 17, 2023, we entered into a sales agreement (Sales Agreement) with Celanese Canada ULC (Celanese) under which Celanese will make available and supply us certain raw materials used to create a nanoporous membrane utilized in the iDose TR, and authorized us to reference its Drug Master File (DMF) with respect to such raw materials, which is required for us to commercialize iDose TR. The term of the Sales Agreement is four years after the iDose TR launch date in February 2024. In exchange for the ability to obtain future raw materials and the rights related to the DMF, we are subject to minimum compensation payments over four years of $6.3 million and potential additional royalties based on a percentage of sales of the iDose TR product. We recognized an intangible asset related to the minimum compensation payments at fair value of $5.2 million upon the date of acquisition, which was determined to be the iDose TR launch date. The $5.2 million is included in Intangible Assets, Net on the condensed consolidated balance sheets and will be amortized to cost of sales over its useful life of four years, which is the initial term of the Sales Agreement.

Market and Business Update

Impact of the Current Global Economic Environment

In connection with ongoing macroeconomic conditions, including inflation, supply shortages or delays, changes in supply and demand, foreign exchange rate fluctuations and other conditions that have led to disruptions in commerce and pricing stability, some of our vendors are continuing to experience supply challenges, both in the acquisition of raw materials as well as due to labor shortages and other disruptions. As a result of these supply chain challenges and due ongoing inflationary pressures, we have experienced higher costs for certain components and raw materials. We expect some supply challenges and higher costs to continue throughout 2024. These challenges have occasionally led to longer lead times and delays of certain components needed for the manufacture of our products, in some cases requiring us to find alternative sources for materials. In the latter part of 2023 and into the first quarter of 2024, these supply challenges generally stabilized; however, if these supply issues persist or worsen in the future, 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. Additionally, unfavorable foreign exchange rates in certain geographies in which we operate negatively impacted our sales during the three months ended March 31, 2023, and to a lesser extent, in the three months ended March 31, 2024.

Developments Impacting Reimbursement Rates and Coverage

In the U.S., healthcare providers use separate billing codes to report the provision of medical procedures and use of supplies to third-party payors, such as government programs or private insurance, and seek reimbursement for all or a portion of those costs. Physician fee payment rates for products covered by temporary Current Procedural Terminology (CPT) codes are set by the multi-state, regional contractors, or Medicare Administrative Contractors (MACs), of which there are currently seven, that are responsible for administering Medicare claims. MACs have in the past, and may in the future, change coverage terms, and there can be no assurance that coverage and adequate reimbursement will be obtained from, or maintained by, the MACs.

In October and November 2023, five of the seven MACs released final local coverage determinations (LCDs) confirming reimbursement coverage of the standalone procedure utilizing the iStent infinite, which received FDA clearance in August 2022, and non-coverage for certain procedures, including the ophthalmic canaloplasty procedure utilizing our iPRIME product. These LCDs also indicated that surgical MIGS procedures should not be performed in combination with other MIGS or surgical glaucoma procedures. In December 2023, prior to their respective effective dates, those five MACs rescinded the final LCDs and determined there would be no change in the current status of coverage for MIGS. The other two MACs have taken preliminary steps to assess coverage of iStent infinite through temporary local coverage article (LCA) updates. In the case of each of these seven MACs, coverage of the iStent infinite is determined on a case-by-case basis.

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 family of products and iDose TR at our facilities in San Clemente, California and our KXL systems at our manufacturing facility in Burlington, Massachusetts. We contract with third-party manufacturers in the U.S. and Germany to produce our Photrexa and other associated drug formulations. We currently intend to maintain our manufacturing facilities at our San Clemente and Burlington locations for the foreseeable future.

Cost of sales includes amortization of the $252.2 million developed technology intangible assets recorded as a result of our acquisition of Avedro, Inc. (Avedro). Amortization expense was $5.5 million for each of the three months ended March 31, 2024 and March 31, 2023.

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 pricing, or conversely, higher product costs. Our gross margin will also be affected by manufacturing or supply chain disruptions or inefficiencies that we may experience as we attempt to manufacture our products on a larger scale, manufacture new products and change our manufacturing capacity, processes, or output. Additionally, our gross margin will continue to be affected by amortization of Avedro developed technology and Celanese Agreement intangible assets, the impact of government pricing programs and by royalty expenses on current or future products associated with various licensing agreements. Our gross margin in future periods may also be impacted by other factors adversely affecting our net sales in future periods such as reductions of payment rates for certain of our products and related services, and inflationary pressures.

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, sales, marketing, market access, financial, legal, and other 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 associated with our global enterprise systems and information systems; and allocated facility expenses.

We expect SG&A expenses to continue to grow as we increase our global sales and marketing infrastructure and general administration infrastructure. We also expect other non-employee-related costs, including sales and marketing program activities for new products, market access efforts, outside services, accounting services 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 research and development (R&D) activities primarily consist of new product development projects, pre-clinical studies, Investigational New Drug studies, and 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; in-licenses, including event-based milestones; 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 they are incurred. We expect our R&D expenses to continue to increase as we initiate and advance our development programs, including our expanding pharmaceutical development efforts and clinical trials across the glaucoma, corneal health and retinal disease spectrums.

Costs for our clinical development programs include expenses for all activities necessary for obtaining regulatory approvals. Our research programs vary significantly for each current and future product candidate and completion dates 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 timing or the amount of costs we will incur in

Table of Contents

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, the availability of funding resources, 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.

Acquired In-Process Research and Development

Our acquired in-process research and development (IPR&D) expenses generally relate to acquisitions of technologies that management determines are not a business combination and do not have any alternative future uses. Future costs to develop these assets are expensed as R&D when incurred. We may have ongoing milestone and royalty payment obligations depending on the success, development, regulatory approval and commercialization of the proprietary technologies we have acquired.

Non-Operating Expense, Net

Non-operating expense, net primarily consists of interest expense associated with our finance lease for our Aliso Facility and for our 2.75% convertible notes due 2027 (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 $7.1 million at March 31, 2024 primarily 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.

Table of Contents

During the three months ended March 31, 2024, we incurred $18.4 million in core R&D expenses and $12.3 million in clinical expenses, comprised of $17.8 million in compensation and related employee expenses with the remaining $12.9 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 next generation iDose products; Epioxa, a pharmaceutical therapeutic system for the treatment of keratoconus without the removal of the epithelium (also referred to as “epi-on”); and our earlier stage programs for glaucoma, corneal, retinal and other therapeutic investments. For the three months ended March 31, 2023, we incurred $20.4 million in core R&D expenses and $14.8 million in clinical expenses, comprised of $18.4 million in compensation and related employee expenses with the remaining $16.8 million spent on the above-mentioned programs.

Acquired In-process Research and Development

During the three months ended March 31, 2024, we issued $5.0 million of our common stock and paid approximately $5.1 million in cash, in connection with the asset acquisition of 100% of the outstanding equity interests in a clinical stage biopharma company focused on developing novel therapeutics for ophthalmic diseases, including all related patents and patent applications, technology and know-how. We may have ongoing milestone payments based on achieving certain clinical and regulatory milestones depending on the success of the development and approval of the proprietary technologies. Also included in IPR&D for the three months ended March 31, 2024 is $1.4 million of contingent consideration related to the aforementioned asset acquisition.

Non-Operating Expense, Net

We had non-operating expense, net of $1.4 million and $1.2 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The change primarily relates to increased interest income earned on investments of $1.4 million, offset by a change in other (expense) income, net of approximately $1.6 million due to recognition of higher unrealized foreign currency losses due to intercompany loan balances denominated in, and impacted by, changes in foreign currency exchange rates, as compared to the three months ended March 31, 2023.

Income Tax Provision

Our effective tax rate for the first quarter of 2024 and 2023 was (0.93)% and (1.17)%, respectively. For each of the three months ended March 31, 2024 and March 31, 2023, we recorded a provision for income taxes of $0.4 million, which was primarily comprised of state and foreign income tax expense.

Liquidity and Capital Resources

Our principal sources of liquidity are our existing cash, cash equivalents and short-term investments, and generally cash generated from operating, financing and investing activities. Our primary uses of cash have been for commercial activities, acquired in-process research and development, clinical and research and development programs, general and administrative expenses, and capital expenditures.

Material Cash Requirements

There have been no significant changes to our material cash requirements, including commitments for capital expenditures and known contractual and other obligations, as of March 31, 2024 from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 23, 2024.

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.

Critical accounting policies and significant estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these condensed 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 condensed 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.

Our critical accounting policies and significant estimates that involve a higher degree of judgment and complexity are described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Significant Estimates” included in Part II, Item 7 of our Annual Report. There have been no material changes to our critical accounting policies and estimates as disclosed therein, during the three months ended March 31, 2024, as compared with those disclosed in our Annual Report.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes in our exposure to market risk since December 31, 2023.

Item 1A. Risk Factors

The risks and uncertainties discussed below update, supersede and replace the risks and uncertainties previously disclosed in Part I, Item IA of our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the United States (U.S.) Securities and Exchange Commission (SEC) on February 23, 2024 (Annual Report). These risks and uncertainties are not the only ones facing our business but do represent those risks that we believe are material to us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also harm our business. Please read the cautionary notice regarding forward-looking statements preceding Part I, Item 1 in this Quarterly Report on Form 10-Q.

Risks Related to Our Business

The commercial success of our recently-approved iDose TR is dependent upon multiple factors, the failure of any one of which could materially impact the prospects of this product and our business.

Our iDose TR travoprost intracameral implant was approved for sale in the U.S. by the FDA in December 2023 and we began commercializing the product in a controlled manner in February 2024. Its commercial success will depend upon a number of factors, including physician adoption of the use of this product, our ability to manufacture product in volumes sufficient to meet customer demand, marketing in compliance with label restrictions, satisfactory patient outcomes, particularly at the outset of our commercial launch, product pricing, duration of efficacy, and the availability of commercial payor coverage and adequate reimbursement for the product. Our failure to successfully commercialize the iDose TR based upon these or other factors could materially adversely impact our net sales, our business or our financial condition.

Unfavorable global and regional conditions have adversely affected, and could in the future materially and adversely affect, our business, results of operations, financial condition, liquidity, and cash flows.

Recent geopolitical conflicts, natural disasters and the public health crises, including COVID-19, have led to or exacerbated certain unfavorable global and regional macroeconomic conditions, including inflation, volatility in the financial and credit markets, higher interest rates and capital costs, labor shortages, increased energy costs, and currency fluctuations, which have had, and could continue to have, an adverse effect on the global economy, the regional economies that we serve and our business, results of operations, financial condition, liquidity and ability to access our existing cash, cash equivalents and investments. Continuation or worsening of these unfavorable global and regional conditions, or similar new events or crises, could have a material adverse effect on our operations, including through foreign exchange rate headwinds, higher operating expenses and lower operating margins, and cause us to need to seek additional capital, which may not be available to us on favorable terms or at all.

In recent years, unfavorable economic conditions have also adversely impacted several financial institutions, including some financial institutions with whom we have banking relationships, and some banks have recently failed and gone into receivership. If banks and other financial institutions with whom we have banking relationships enter receivership or become insolvent in the future, we may be unable to access, and we may lose, some or all of our existing cash and cash equivalents to the extent those funds are not insured or otherwise protected by the FDIC.

Public health crises, such as the COVID-19 pandemic, have adversely affected, and could in the future adversely affect, our business, results of operations, financial condition, liquidity, and cash flows.

We are subject to risks associated with public heath crises, including those related to the COVID-19 pandemic. The COVID-19 pandemic has had, and could continue to have, an adverse effect on our business, results of operations, financial condition, liquidity and cash flows. Other future public health crises, such as the avian influenza, may also have a negative impact on our business. In particular, we have experienced, and may in the future experience, financial or operational impacts as a result of such public health crises which may be material, including:

Table of Contents

●

Impacts or delays to our product development efforts, including due to slowdown of new patient enrollment in clinical trials such as we experienced in our 2020 and 2021 iDose clinical trial, or regulatory clearances and approvals;

●

Costs associated with protecting the health of our employees and adhering to any guidance or orders of various governmental authorities, such as masking, testing, and social distancing requirements;

●

Risks associated with remote work, including increased cybersecurity risk;

●

Widespread staffing shortages and turnover, including in ambulatory surgery centers, and mandatory and voluntary quarantining, which may impact elective procedures;

●

Outbreaks of disease in our facilities, which could require us to temporarily shut down manufacturing operations or cause a disruption to, or shortage in, our workforce;

●

Delays in shipments of our products, which could harm our customer relations and adversely impact our competitive positioning and sales, including as a result of longer lead times, delays, higher prices and unfulfilled deliveries of our supply chain and development partners, each of which we continued to experience in 2023 and anticipate will continue into the near future;

●

Restrictions on our personnel’s ability to access customers and clinical sites for training and support; and

●

Volatility in credit or financial markets.

If the supply and/or manufacture of our principal revenue-producing products, the iStent family of products, our Photrexa therapies, or that of our newly-commercialized iDose TR is materially disrupted, it may adversely affect our ability to manufacture products and could reduce our gross margins and negatively impact our operating results.

Our sole manufacturing location for our iStent and iDose products is an approximately 120,000 square foot campus located in San Clemente, California, where we manufacture, inspect, package, release and ship nearly all of our implanted device products. We conduct substantially all of our research and development (R&D) activities, customer and technical support, and management and administrative functions at our corporate headquarters in Aliso Viejo, California (Aliso Facility). If either of our San Clemente or Aliso Facility suffers a crippling event or a natural disaster such as an earthquake, fire or flood, this could materially impact our ability to operate.

Additionally, we rely on a limited number of third-party suppliers, in some cases sole suppliers, to supply components for the iStent, the iStent inject models, the iStent infinite, the iDose TR, and our other pipeline products. If any one or more of our suppliers cease to provide us with sufficient quantities of components or drugs in a timely manner or on terms acceptable to us, we would have to seek alternative sources of supply. Because of factors such as the proprietary nature of our products, our domestic and international quality control standards and regulatory requirements including the FDA’s Quality System Regulation, the European Union’s Medical Device Regulation, and Current Good Manufacturing Practices regulations, we may be unable to obtain components or quickly engage replacement suppliers, who may not have access to previous suppliers’ proprietary processes, if our component suppliers are found to be in violation of such standards, which could delay or impact our business, including regulatory approval timelines. If our manufacturing facilities or those of any of our component suppliers or contract facilities are found to be in violation of applicable laws and regulations or fail to adequately remediate any issues discovered during an audit, the FDA or other regulatory bodies could take enforcement action. Despite our efforts to maintain an adequate supply of inventory, the loss of these suppliers, or their inability to provide us with an adequate supply of components or products, could cause delay in the manufacture of our products, thereby impairing our ability to meet the demand of our customers and causing significant harm to our business. Any disruption of this nature or increased expense could harm our commercialization efforts and adversely affect our operating results.

Our corneal health Photrexa therapies are produced by a small number of contract manufacturing organizations. The systems that bio-activate our Photrexa therapies are primarily manufactured in Burlington, Massachusetts. Any material disruption to the manufacture of these corneal health products could also adversely affect our operating results and clinical efforts.

We have incurred significant losses since inception and our operating results can be unpredictable and may fluctuate significantly from quarter to quarter, requiring substantial capital and operating expenditures for our business to operate and grow. These factors could adversely affect our business, financial condition, results of operations and the trading price of our common stock, and limit our ability to reach sustained profitability.

Since the Company’s inception in 1998, we have incurred significant operating losses. 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. As of March 31, 2024, we had an accumulated deficit of approximately

Table of Contents

$639.9 million, principally comprised of costs incurred in our clinical trials, R&D programs, our selling, general and administrative expenses, and from amortization expense related to our acquired developed technology intangible assets included in cost of sales. We have funded our operations to date from the sale of equity securities, including our June 2015 initial public offering, the issuance of notes payable, cash exercises of stock options and warrants to purchase equity securities, cash generated from commercial operations and the issuance of the Company’s 2.75% convertible notes due 2027 (Convertible Notes). Our operations to date have been, and our future growth and success will be, impacted by our ability to expand our business, including the success of our marketing and sales efforts, our timely satisfaction of regulatory requirements, and our overall ability to maintain a competitive position. To implement our global business strategies we have made, and expect to continue to make, significant investments in R&D activities, clinical studies, expanding our manufacturing capabilities, growing our sales and marketing organization, engaging in market access activities, enforcing and defending our intellectual property rights, acquiring companies or in-license products and intellectual property, building our general and administrative infrastructure, and obtaining regulatory clearance or approval to commercialize our pipeline product globally and expand our existing products into international markets or products We expect our expenses will continue to increase as we pursue these objectives. While we believe we have sufficient cash to fund our operations for at least the next 12 months from the date our condensed consolidated financial statements for the quarter ended March 31, 2024 are made publicly available, our ability to reach sustained profitability and generate positive cash flow in the future is highly uncertain.

Additionally, our net sales may experience volatility due to a number of factors, many of which are beyond our control, including, among other things, fluctuating demand, pricing pressures applicable to our products, changes in foreign currency exchange rates, Medicare payment rates established by U.S. Centers for Medicare & Medicaid Services (CMS) or Medicare Administrative Contractors (MACs), commercialization of our new products, the marketing of competitive products, results of clinical research and trials, regulatory approval requirements and timings, legislative changes affecting our products, variances in the sales terms, an increase in demand for our patient assistance and/or free drug programs, supply chain and inventory management, shortage of raw materials, seasonality in the timing or volume of customer orders, the length of our sales cycle, and reductions in revenue associated with our participation in Medicaid Drug Rebate Program (MDRP), which varies and may be unpredictable. As a result, you should not rely solely on our results in any past period as an indication of future results and you should anticipate that fluctuations in our quarterly and annual operating results may continue and could generate volatility in the price of our common stock. We believe that quarterly comparisons of our financial results should not be relied upon as an indication of our future performance.

Our success depends on our ability to continue to generate sales of our commercialized products and develop and commercialize additional products, which we may not be able to accomplish.

Our primary sales-generating commercial products have been the iStent, the iStent inject and its successor, the iStent inject W, as well as our Photrexa therapies, which we acquired in connection with our acquisition of Avedro, Inc. (Avedro) in 2019. While we expect to continue to derive a significant portion of our net sales from the iStent, the iStent inject models, the iStent infinite and the Photrexa therapies, as well as our iDose TR product, which was approved by the FDA in December 2023 and which we began commercializing in a controlled manner in February 2024, it is important that we continue to build a more complete product offering. Developing additional products is expensive and time-consuming. Our research programs may fail to yield product candidates for clinical development despite showing initial promise. If we are unable to successfully commercialize additional products, our business prospects would be materially affected. Even if we are successful in developing our additional pipeline products, the success of our new product offerings is inherently uncertain and our products may not receive regulatory approval, may receive approval that requires restrictive labeling, or may not be profitable. Any current or new products could also quickly be rendered obsolete by changing customer preferences, third party payor reimbursement levels, or the introduction of competing products that (i) embody superior technologies, features, safety, quality or efficacy, (ii) reflect a broader label indication, or (iii) are available at lower prices. Our competitors include large publicly traded companies or divisions thereof and have more resources, greater name recognition, longer operating histories, more established relationships with healthcare professionals, customers and third-party payors, broader products lines, more established sales and marketing programs and distribution networks, and greater experience in obtaining regulatory clearance or approval. Additionally, the period of orphan drug exclusivity with respect to our Photrexa pharmaceutical therapy expired in 2023, which could allow competitive products to enter that market.

third-party components or other elements, may be difficult, which increases the time needed to address quality issues as they arise and increases the risk that similar problems could recur. Finding solutions to quality issues can be expensive and we may incur significant costs, lost revenue or reputational damage in connection with, for example, shipment holds, product recalls and warranty or other service obligations. Quality issues can also impair our relationships with new or existing customers or result in product liability suits against us, which may be expensive to defend and could impact the reimbursement coverage of our products, our product liability insurance rates and/or our cash reserves in the event our existing insurance coverage is insufficient. The occurrence of any of the foregoing could harm our reputation as a producer of high-quality products and could adversely affect our business, financial condition or results of operations.

Ophthalmic surgeons may not use our products if they do not believe they are safe, efficient, effective and preferable alternatives to other treatment solutions in the market or may use our products without being adequately trained, which could result in inferior clinical outcomes.

We believe that ophthalmic surgeons will not use our products unless they conclude that our products provide a safe, efficient, effective and preferable alternative to currently available treatment options. Publications of clinical results by us, our competitors and other third parties may impact whether, and the degree to which, our products are used by physicians and the procedures and treatments those physicians choose to administer to their patients. If ophthalmic surgeons determine that any of our products are not sufficiently effective, efficient or safe, whether based on longer-term patient studies or clinical experience or unsatisfactory patient outcomes or patient injury, our sales would be harmed. Surgeons may base such determination on patient outcomes that are the result of other unqualified surgeons performing procedures for which they haven’t been trained. It is also possible that as our products become more widely used, latent defects could be identified, creating negative publicity and liability problems for us and adversely affecting demand for our products. If an increasing number of ophthalmic surgeons do not continue to adopt the use of our products, our operating and financial results will be negatively impacted.

If we fail to manage our anticipated growth effectively, we may not be able to meet customer demand for our products and our business could suffer.

Since the commercial launch of the iStent in 2012, we have seen significant period-to-period growth in our business, both organically and through transactions, and we must continue to grow in order to meet our business and financial objectives. However, continued growth creates numerous challenges, including, among others, new and increased responsibilities for our management team; increased competition; increased and, with respect to new products such as the iDose TR, uncertain product demand which could strain our manufacturing capacity or create product shortages; the management of an increasing number of customer, supplier and other relationships; increased pressure on our operating, financial and reporting systems; entry into new international territories with unfamiliar regulations and business approaches; and the need to hire, train and manage additional qualified personnel. If we fail to manage any of these challenges effectively, our business may be harmed.

If we are unable to retain or recruit qualified personnel for growth, our business results could suffer.

We have benefited substantially from the leadership and performance of our senior management and other key employees. For example, our chief executive officer, as well as other key members of our senior management, has experience successfully developing novel technologies and scaling early-stage medical device and pharmaceutical companies to achieve profitability. We also rely on our qualified sales representatives and on consultants and advisors in our research, operations, clinical and commercial efforts to grow our business, develop and commercialize new products and implement our business strategies. Our success will depend on our ability to retain our current management and key employees, consultants and advisors, and to attract and retain qualified personnel in the future, including by providing competitive compensation and benefit programs, flexible work arrangements, career advancement prospects and sufficient opportunities to develop leadership, managerial and other valuable skills. The loss of services of these personnel, which could occur without notice and without cause, could prevent or delay our growth plans and the implementation of our strategic objectives, or divert management’s attention to seeking qualified replacements. Our U.S. employees, including our senior management, are not subject to non-competition agreements. Accordingly, the adverse effect of losing key personnel could be compounded by our inability to prevent them from competing with us.

We have and may continue to enter into acquisitions, collaborations, in-licensing agreements, joint ventures, alliances or partnerships with third parties that could fail.

We have and may continue to enter into acquisitions, collaborations, in-licensing agreements, joint ventures and partnerships in order to retain our competitive position within the marketplace, develop new products or expand into new markets. Examples include our acquisitions of DOSE Medical and Avedro, as well as our licensing of Santen’s PRESERFLO® Microshunt® (Preserflo MicroShunt), the Intratus drug delivery platform and the Attillaps, iVeena, Stuart and Ripple pharmaceutical compounds and our collaboration agreement with Radius XR to market its wearable patient engagement and diagnostic system. However, we cannot assure you that we will be able to successfully complete any future acquisition we may pursue, or that we will be able to successfully integrate any acquired business, product or technology in a cost-effective and non-disruptive manner. Our future successes will depend, in part, on our ability to manage an expanded business, which may pose substantial challenges for our management, such as increased costs and complexity. There can be no assurances that we will be successful in managing such expanded business or that we will realize the expected economies of scale, synergies and other benefits currently anticipated from recent or future acquisitions or strategic transactions. Additionally, these collaborations, joint ventures, and partnerships may fail to result in any commercialized product, including due to delays in or failures to obtain regulatory approvals, such as the failure to receive approval of the PreserFlo MicroShunt in the U.S., and could require us to invest a substantial amount of resources only to ultimately change regulatory strategies or to fail. In addition, these arrangements may be terminated before we are able to realize net sales to sufficiently cover the costs associated therewith, which could materially impact our business. We cannot assure you that any such transaction would result in the benefits expected from the transaction, including revenue growth, increased profitability or an enhancement in our business prospects. Further, pursuing acquisitions, collaborations, in-licensing agreements, joint ventures, alliances or partnerships with third parties, whether or not completed, is costly and time-consuming and could distract Company management from the operation of the business, which could negatively impact our operating results.

Failure to protect our information systems against cybersecurity threats, cybersecurity incidents, service interruptions, or data corruption could materially disrupt our operations and adversely affect our business, operating results, or the effectiveness of our internal controls over financial reporting.

The efficient operation of our global business depends on our information systems, including telecommunications, the internet, network communications, email and various computer hardware and software applications. We rely on our information systems to effectively manage sales and marketing data, accounting and financial functions, inventory management, product development tasks, clinical data, quality systems, customer service and technical support functions. Our information systems are vulnerable to damage or interruption from earthquakes, fires, floods and other natural disasters, terrorist attacks, power losses, computer system or data network failures, data corruption and security breaches or other cybersecurity incidents, some of which we have experienced and which we continue to monitor. Cybersecurity incidents can include ransomware, computer denial-of-service attacks, worms, and other malicious software programs introduced to our computers and networks, including intrusions that are designed to evade detection for an extended period of time, phishing attacks, social engineering attacks, and efforts to discover and exploit any design flaws, bugs, security vulnerabilities or weaknesses, as well as intentional or unintentional acts by employees or other insiders with access privileges, intentional acts of vandalism or fraud by third parties and sabotage. Additionally, cybersecurity threats and the techniques used in cyberattacks change, develop and evolve rapidly, including from emerging technologies, such as advanced forms of AI and quantum computing. While none of the cybersecurity incidents or service interruptions that we have experienced to date have had a material adverse impact on our business, financial condition or operations, the preventative measures we have implemented to date may not be sufficient to prevent, mitigate or offset a future incident that may materially and adversely impact us and the cybersecurity insurance we have obtained may or may not cover such an incident. In addition, some of our software systems are cloud-based data management applications, hosted by third-party service providers whose security and information technology systems are subject to similar risks. The failure to protect either our or our service providers’ information technology infrastructure could disrupt our entire operation, resulting in decreased sales, increased overhead costs, product shortages, or loss or misuse of intellectual property or proprietary, confidential, sensitive or personal information, all of which could have a material adverse effect on our reputation, business, financial condition and operating results or result in investigations, claims and administrative penalties by regulators.

Our enterprise resource planning (ERP) system is integral to our ability to accurately and efficiently maintain our books and records, record transactions, and prepare our financial statements. Any disruptions or difficulties that may occur in connection with our ERP system (whether in connection with the regular operation, periodic enhancements or

Table of Contents

upgrades of such systems, or due to cybersecurity incidents) could adversely affect our ability to provide services, fulfill contractual obligations, file reports with the SEC in a timely manner, operate our business or otherwise affect our controls environment. If our independent registered public accounting firm determines that we have a material weakness in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the New York Stock Exchange, the SEC, or other regulatory authorities. Any of these events could have an adverse effect on our operating results and financial condition.

Failure to comply with data privacy and security laws could have a material adverse effect on our business.

We are subject to state, federal and foreign laws relating to data privacy and security in the conduct of our business, including state breach notification laws, the Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, the European Union’s General Data Protection Regulation (GDPR), the U.K. Data Protection Act and the U.K. GDPR, the California Consumer Privacy Act, and the California Privacy Rights Act, among others. These laws affect how we collect and use data of our employees, consultants, customers and other parties, including patients treated with our products. They may further restrict our transfer and use of such data, and may allow individuals to make requests or exercise rights that could limit use of data and require the expenditure of significant resources and time and effort to address. These laws, as well as similar laws being enacted by other states and countries, impose substantial requirements that involve the expenditure of significant resources and the investment of significant time and effort to comply. We also rely on third parties to host or otherwise process some of this data. In some instances, these third parties have experienced failures to protect data privacy. Our failure or the failure of these third parties to comply with these laws or prevent security breaches of such data could result in significant liability, fines and penalties under applicable data privacy laws, cause disruption to our business, harm our reputation and have a material adverse effect on our business.

We cannot be certain that our net operating loss tax carryforwards will be available to offset future taxable income.

At December 31, 2023, we had approximately $463.1 million, $355.3 million and $9.4 million of net operating loss (NOL) carryforwards for federal, state and foreign purposes, respectively. A portion of federal NOL carryforwards incurred prior to 2018 will expire annually, if unused, while $257.6 million will not expire but can only be used to offset 80 percent of federal taxable income. Additionally, portions of state and foreign NOL carryforwards will expire annually, if unused.

At December 31, 2023, we had federal and state R&D credit carryforwards of approximately $43.8 million and $25.0 million, respectively. Portions of federal and $4.4 million of state credits will expire annually, if unused, while $20.6 million of state credits carry forward indefinitely. Additionally, as of December 31, 2023, we expect to be awarded a total of $3.0 million in California economic development credits which can be used to offset California taxable income. These credits begin to expire in 2028, if unused.

We continue to provide a valuation allowance against a portion of these tax attributes because we believe that uncertainty exists with respect to their future realization. Utilization of these tax attributes may be subject to annual limitations under IRC Sections 382 and 383 if the Company experiences an ownership change. To the extent available, we intend to use these NOL and credit carryforwards to offset future taxable income and/or income tax liabilities associated with our operations. There can be no assurance that we will generate sufficient taxable income in the carryforward period to utilize the remaining tax attributes before they expire.

Risks Related to Our Indebtedness

The requirement that we service our indebtedness could limit the cash flow available for our operations and have other consequences that could adversely affect our business, and we may not have sufficient cash flow from our business to pay our debt obligations.

As of December 31, 2023, we had $287.5 million in principal amount of indebtedness as a result of the issuance of the Convertible Notes. We may also incur additional indebtedness to meet future financing needs. Interest payments, fees, covenants and restrictions under agreements governing our current or future indebtedness, including the indenture governing the Convertible Notes, could have significant consequences, including the following: impairing our ability to successfully continue to commercialize our current or future products; limiting our ability to obtain additional financing

Table of Contents

on satisfactory terms; increasing our vulnerability to general economic downturns, competition and industry conditions; requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness; inhibiting our flexibility to plan for, or react to, changes in our business; and diluting the interests of our existing stockholders if we issue shares of our common stock upon conversion of the Convertible Notes. The occurrence of any one of these events could have an adverse effect on our business, financial condition, operating results or cash flows and ability to satisfy our obligations under the indenture governing the Convertible Notes and any other indebtedness.

Our ability to make scheduled payments of the principal and interest on, or to refinance the amounts payable under, our current or future indebtedness, including the Convertible Notes, while still making necessary investments in our business, will depend on our operating and financial performance, including our ability to generate sufficient cash flow from operations, which may be subject to economic, financial, competitive and other factors beyond our control. If we are unable to generate such cash flow, we may be required to sell assets, restructure existing debt or obtain additional debt financing or equity capital on terms that may be onerous or highly dilutive. Our ability to refinance any future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or secure desirable terms, which could result in a default on our debt obligations.

The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the Convertible Notes is triggered, as it was for the quarter ended March 31, 2024, holders of the Convertible Notes will have the option to convert the Convertible Notes at any time during specified periods. If one or more holders elect to convert their Convertible Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

We may not have the ability to raise the funds necessary to settle conversions of the Convertible Notes in cash or to repurchase the Convertible Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the Convertible Notes.

Noteholders may require us to repurchase their Convertible Notes upon the occurrence of a fundamental change at a repurchase price equal to 100% of the aggregate principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, upon conversion of the Convertible Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Convertible Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of the Convertible Notes surrendered or Convertible Notes being converted. In addition, our ability to repurchase the Convertible Notes or to pay cash upon conversions of the Convertible Notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase Convertible Notes, or to pay any cash payable on future conversions of the Convertible Notes as required by the indenture governing the Convertible Notes would constitute a default under the indenture governing the Convertible Notes, which event, or the occurrence of the fundamental change itself, may lead to a default under any future credit facility or other agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Convertible Notes or make cash payments upon conversions thereof.

The capped call transactions may affect the value of our common stock, and subject us to counterparty risk.

In connection with the issuance of the Convertible Notes, we entered into capped call transactions with certain option counterparties. The capped call transactions cover, subject to customary adjustments, the number of shares of common stock initially underlying the Convertible Notes. The capped call transactions are expected generally to reduce the potential dilution of our common stock upon any conversion of the Convertible Notes or at our election (subject to certain conditions), offset any cash payments we are required to make in excess of the aggregate principal amount of converted Convertible Notes, as the case may be, with such reduction or offset subject to a cap. We have been advised that the option counterparties or their respective affiliates have established initial hedges of the capped call transaction, and may modify their hedge positions by entering into or unwinding various derivative transactions with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market

Table of Contents

transactions prior to the maturity of the Convertible Notes (and are likely to do so on each exercise date of the capped call transactions, which are expected to occur during the 40 trading day period beginning on the 41st scheduled trading day prior to the maturity date of the Convertible Notes, or following any termination of any portion of the capped call transactions in connection with any repurchase, redemption or early conversion of the Convertible Notes). This activity could impact the market price of our common stock.

The option counterparties to the capped call transactions are financial Institutions, and we are subject to the risk that any or all of them might default under the capped call transactions. Our exposure to the credit risk of the option counterparties is not secured by any collateral. Past global economic conditions have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the capped call transactions with such option counterparty. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price subject to the cap and in the volatility of our common stock. In addition, upon a default by an option counterparty, we may suffer more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the option counterparties.

Risks Related to Our Regulatory Environment

Our business, products and processes are subject to extensive regulation both in the U.S. and abroad and it can be costly to comply with these regulations. Any failure to adhere to applicable regulations could harm our business, financial condition and operating results.

Our medical devices, drugs, drug/device combination products and other products are subject to extensive government regulation in the U.S. by the FDA, state regulatory authorities and foreign regulatory authorities in the countries in which we conduct business. These regulations relate to, among other things, approval or clearance of our products for sale, R&D, labeling, advertising, promotion, pricing and discounts, recordkeeping, reporting, import and export, post-approval studies and the sale and distribution of our products. See Item 1, Business, “Government Regulation – U.S. Regulation & Reimbursement” and “International Regulation & Reimbursement” in our Annual Report for additional information. Our failure to comply with applicable regulatory requirements could result in enforcement action by the FDA, or state or foreign regulatory authorities, which may include, among other things, warning letters, fines, injunctions, recalls, refusals to grant or delays in granting requests, civil fines and penalties, operating restrictions, withdrawal of approvals and even criminal prosecution.

The process of obtaining clearances or approvals to market our products can be expensive and lengthy, and we cannot guarantee that our current products will receive clearance or approval for additional indications or that our future products will receive clearance or approval on a timely basis, or without restrictions, if at all. Additionally, based upon a recent FDA determination, our pipeline products that are determined to be drug-device combination products, such as our iDose TR product, will require review and coordination by each of FDA’s drug and device centers prior to approval, which may delay approval. In some instances, we or our partners have pursued, and may in the future pursue, a regulatory clearance or approval that proves unsuccessful, such as the FDA’s recent failure to approve the PreserFlo Microshunt in the U.S. and our determination to conduct a second pivotal confirmatory study of our Epioxa pharmaceutical therapy based on recommendations from the FDA in pre-NDA submission meetings. When this occurs, the time and financial resources required to obtain FDA or other regulatory approval may substantially increase or new competitive products could reach the market faster than our product candidate, which could materially adversely impact our competitive position and prospects. We cannot assure you that we will receive the requisite approvals to sell our product candidates on our anticipated timeline or at all.

Before we can obtain regulatory approval for any product candidate, we may have to undertake complex, time-consuming and expensive clinical testing in humans to demonstrate safety and efficacy, the outcomes of which are inherently uncertain and may never result in approved products or commercial sales. We have experienced in the past, and could experience in the future, delays in the commencement or completion of clinical trials or testing that could significantly affect our product development costs. We do not know whether planned clinical trials will begin on time, need to be redesigned, enroll an adequate number of patients in a timely manner or be completed on schedule, if at all, or be deemed insufficient by the FDA, which may require additional lengthy, time-consuming and expensive trials, which would further delay approval. We may suffer significant setbacks in clinical trials, even after earlier trials showed promising results, and failure can occur at any time during the clinical trial process. We, the clinical trial investigators, the independent review board overseeing the trial, the FDA, or another regulatory authority may suspend, delay or

Table of Contents

terminate clinical trials at any time due to a number of factors, including failure to conduct the trial in accordance with applicable regulatory requirements or trial protocols, failure to demonstrate a benefit from using the product, lack of sufficient funding, medical device product malfunctions, adverse events, or to avoid exposing trial participants to unacceptable health risks. Any delay or failure in clinical trials would delay or prevent our ability to obtain necessary regulatory approvals, which would have a material adverse effect on our business, financial condition and prospects.

As part of the PMA regulatory application and approval process, the FDA will generally conduct a pre-approval inspection of the applicant or its third-party manufacturers’ or suppliers’ manufacturing facilities to ensure compliance with the FDA’s Quality System Regulation (QSR) for medical devices or current Good Manufacturing Practice (cGMP) regulations for drug and combination products, such as our iDose TR product. If our facilities, or those of our third-party manufacturers or suppliers, fail to meet the QSR or cGMP regulations, as applicable, or other standards required by the FDA, we could experience a delay in obtaining the necessary regulatory clearances or approvals to commercialize our pipeline products, which could have a material adverse effect on our business and financial condition and results.

Even after we have obtained the proper regulatory clearance or approval to market a product, we have ongoing responsibilities under FDA regulations and applicable foreign laws and regulations. We may also be required to seek additional regulatory approvals to modify our approved products or their manufacturing processes or indications, which may entail significant time and expense. We and our suppliers are subject to extensive post-marketing regulatory requirements including post-marketing studies, and failure to comply with applicable requirements in a timely manner could subject us to enforcement actions, including recall or product approval withdrawals. Compliance with applicable regulatory requirements is subject to continual review and is monitored rigorously through periodic inspections by the FDA. Other post-market requirements on our products include establishment registration and device listing, quality system and good manufacturing requirements, reporting of adverse events and device malfunctions, product tracing, reporting of corrections and removals (recalls), labeling requirements, and promotional restrictions. Under FDA regulations, combination products are subject to the quality system and good manufacturing requirements applicable to both drugs and medical devices. Our products could malfunction, cause unexpected adverse events, or experience performance problems that require review and possible corrective action by us or a component supplier, including a recall or market withdrawal. Any recall or product withdrawal, whether required by the FDA or another regulatory authority or initiated by us, could harm our reputation with customers, cause us to incur significant expense and negatively affect our sales.

In addition, our promotional materials, sales techniques, pricing programs and training methods must comply with FDA and other applicable laws and regulations, including the prohibition of the promotion of a drug or medical device for a use that has not been cleared or approved by the FDA or other regulatory authorities, also known as an “off-label” use. The FDA or other regulatory authorities may limit the indications for use of our products, thereby restricting our ability to promote the drug or device. Physicians may use our products, particularly newly-approved products, off-label or in combination with other products that are not indicated or appropriate, as the FDA does not restrict or regulate a physician's choice of treatment within the practice of medicine. However, if the FDA determines that our promotional materials, sales techniques, pricing programs or training constitutes promotion of an off-label use or encourages over-utilization of our products or use of our products in combinations that are not indicated or appropriate, it could request that we modify our materials, techniques, programs or training or subject us to enforcement actions.

We are subject to healthcare fraud and abuse, anti-kickback, false claims and transparency laws and regulations, among others, which are enforced by federal, state and international governments with respect to our marketing, training, customer arrangements, discount, rebate and pricing programs, product bundling, financial arrangements with physicians, patient assistance programs, reimbursement support services, and other practices. See Item 1, Business, “Government Regulation – U.S. Regulation & Reimbursement” and “International Regulation & Reimbursement” contained in our Annual Report for additional information about the laws and regulations which apply to us. The U.S. Department of Justice has increased its scrutiny of interactions between manufacturers and healthcare providers, as well as various patient, product and reimbursement support programs and speaker bureaus, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Although we try to structure our arrangements within available safe harbors whenever possible, we may nevertheless become subject to government scrutiny or investigation. Violations may result in civil monetary penalties, criminal penalties, and exclusion from participation in government healthcare programs, including Medicare and Medicaid, all of which would have an adverse effect on our business.

Table of Contents

We are also subject to compliance with various anti-bribery laws and regulations, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act, and similar anti-bribery laws in other jurisdictions, which generally prohibit companies and their agents from making bribes or other improper payments to officials for the purpose of obtaining or retaining business. We are also subject to limitations on trade with persons in sanctioned countries. Our sales in international markets increase the inherent risks of encountering such issues. While our employees, distributors and agents are required to comply with these laws and regulations, no assurance can be given that our training efforts and internal policies and procedures will prevent violations of these laws. Any actual or alleged violations of these laws and regulations could subject us to government investigations, criminal sanctions, severe fines and penalties that could have a material adverse impact on our reputation, financial condition, results of operations and cash flows.

The scope and enforcement of each of the laws applicable to our business and products is uncertain and subject to rapid change in the current environment of healthcare reform. If our operations are found to be in violation of any of the government regulations that apply to us, we may be subject to civil and criminal penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in federal and state healthcare programs and the curtailment or restricting of our operations, any of which could harm our ability to operate our business and our financial results. Responding to a government investigation is time and resource intensive, and may cause harm to our business and reputation even if we are able to successfully defend against it. Additionally, resolution of any such investigation may require agreement to onerous corporate integrity agreements or other compliance or reporting requirements, which may negatively affect our business.

Legislative or regulatory reform of the healthcare system could hinder or prevent our products’ commercial success.

In the U.S. and in certain states and foreign jurisdictions, there have been a number of legislative and regulatory proposals and adoptions to change the healthcare systems in ways that could impact our ability to sell our products profitably, if at all. In addition, new regulations and interpretations of existing healthcare statutes and regulations are frequently adopted and we may not be able to comply with the changed laws, they could increase the cost of manufacturing, marketing or selling our product, could make approvals of pipeline products more difficult or prevent us from selling at all. We expect there will continue to be a number of legislative and regulatory changes to the U.S. health care system that could significantly change the statutory provisions governing the regulatory approval, manufacture and marketing of regulated products or the reimbursement thereof and may impose additional costs or lengthen review times of planned or future products. It is also difficult to predict whether and how the policies and priorities of a new administration could materially impact the regulation governing our products.

In 2017, the EU adopted Medical Devices Regulation 2017/745 (MDR), which repealed and replaced the Medical Device Directive (MDD). MDR went into effect in May 2021 and provides for stricter controls of medical devices than did MDD. Under provisions that govern the transition from MDD to MDR, qualifying medical devices with notified body certificates issued under the MDD prior to May 2021 may continue to be marketed and sold through 2028. After the expiration of any applicable transitional period, only devices that have been CE marked under MDR may be placed on the market in the EU. Additionally, the bio-activated therapy used with our crosslinking device to treat keratoconus in international markets, which is currently classified as a medical device in the EU and certain other countries, could be reclassified as a drug product, which would impose an entirely new regulatory framework on us and our contract manufacturers for this product, and compliance may prove costly and difficult or may not be achievable at all. Our failure, or the failure of our contract manufacturers, to obtain CE marks for all of our products under MDR on a timely basis, or to comply with MDR or applicable European Medicines Agency regulations regarding drug products, could restrict our ability to sell our products in the EU or other parts of the world, which would have a material adverse effect on our business and financial results.

From time to time, we increase the prices of our products, as we have previously done with our Photrexa therapies. Drug pricing by pharmaceutical manufacturers is subject to federal and state reporting requirements and is currently, and is expected to continue to be, under close scrutiny, including with respect to manufacturers that increase the price of products after acquiring those products from other companies. In some cases, such scrutiny has resulted in congressional inquiries and federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturers’ patient support programs, and reform government program reimbursement methodologies for products. Although our price increases have been based upon third party studies of the projected economic value of our products to the healthcare system, they may still become subject to such scrutiny.

As a condition of having our recently-approved iDose TR product covered under certain federal healthcare programs such as Medicare and Medicaid, we are required to participate in the MDRP with respect to all of our pharmaceutical products, which requires us to calculate and report certain pricing metrics to the government, comply with certain pricing limitations any pay a rebate to each state Medicaid program for our covered products based on utilization of our products by Medicaid beneficiaries. Any company that participates in the MDRP also must participate in the 340B drug pricing program (the “340B program”). The 340B program, which is administered by the Health Resources and Services Administration, requires participating companies to agree to charge statutorily defined covered entities no more than the 340B “ceiling price” for covered outpatient drugs. The 340B ceiling price is calculated using a statutory formula, which is based on pricing data calculated under the MDRP. Additionally, the U.S. Inflation Reduction Act of 2022, which is designed to, among other things, have a direct impact on drug prices and reduce drug spending by the federal government, requires drug manufacturers to pay rebates to Medicare if they increase prices faster than inflation for certain drugs used by Medicare beneficiaries. The expansion of inflation-based rebates may complicate our pricing strategies. To the extent applicable, these and other similar legislation or regulations will reduce the prices we can charge, and impact the rebate amount we must pay, on sales of our products subject to that act, particularly on sales to our customers if they qualify as covered entities eligible to receive the discounted 340B ceiling price. Compliance with these laws and programs may reduce our net sales, and could require significant resources, which would reduce our profitability. Additionally, we cannot predict how our participation in, or how future CMS guidance or rules governing, MDRP will affect our profitability (including the potential for increases in our overall Medicaid rebate liability and the obligation to charge reduced prices to covered entities). Any changes to the limitations, calculations, or scope of these programs could negatively impact the results of our operations.

If we cannot sell our products profitably, whether due to our own inability to comply with, or the inability of other economic operators in our supply chain to qualify under, any legislative reform or pricing programs, our business would be harmed. In addition, any change in the laws or regulations that govern the clearance and approval processes relating to our current and future products could make it more difficult and costly to obtain clearance or approval for new products, or to produce, market and distribute existing products.

Inadequate or inconsistent reimbursement for our products may adversely impact our business.

Our ability to successfully commercialize and achieve market acceptance of our products and compete against other therapies designed to address the same disease states depends in significant part on adequate financial coverage and reimbursement from third party payors, including governmental payors (such as the Medicare and Medicaid programs in the U.S.), managed care organizations and private health insurers. See Item 1, Business, “Government Regulation – U.S. Regulation & Reimbursement” and “International Regulation & Reimbursement” contained in our Annual Report for additional information. Payors continually review the clinical evidence for new therapies and can change their coverage policies without notice or deny payment if the product was not used in accordance with the payor’s coverage policy. Therefore, coverage for our products can differ significantly from payor to payor. In addition, payors continually review new therapies for possible coverage and can, without notice, deny coverage for these products and procedures. As a result, the coverage determination process is often time-consuming and costly and requires us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage will be obtained or will be maintained once it is obtained.

In addition to uncertainties surrounding coverage policies, there are uncertainties regarding appropriate reimbursement for the procedures associated with our new products like iAccess, a precision blade, iPRIME, a viscoelastic delivery system, and iStent infinite as well as sporadic volatility in reimbursement levels of existing products, including our Photrexa therapy and the procedures associated with our existing products, such as our iStent family of products. For example, in 2022 the CMS’ payment rates significantly lowered the Medicare physician fee payment rates and slightly lowered the Medicare facility fee payment rates related to the implantation of trabecular bypass stents, such as our iStent family of products, in conjunction with cataract surgery, furnished in the ambulatory surgery center (ASC) setting, which we believe disrupted traditional customer ordering patterns and resulted in our customers’ trialing and utilization of competitive products, causing reduced glaucoma sales volumes in the U.S. in 2022 and 2023. Additionally, the facility fee payment rates for the standalone procedure that hospitals and ambulatory surgery centers will use with Glaukos’ iStent infinite product were lower than anticipated for 2022 and were not significantly modified by CMS for 2023 facility fee payment rates. While CMS’ 2024 Medicare payment rates increased facility fee payment rates related to the implantation of trabecular bypass stents, such as our iStent family of products, both in conjunction with cataract surgery and as a standalone procedure, in both the ASC and hospital setting, we expect the reduced physician fee payment rates to have an adverse impact on procedural iStent family product volumes, in

Table of Contents

conjunction with cataract surgery and on a stand-alone basis, in 2024 as well as on our U.S. combo-cataract glaucoma revenues, gross profit, and net income.

The demand for, and the profitability of, our products could be materially harmed if the Medicaid program, Medicare program, other healthcare programs in the U.S. or elsewhere, or third party commercial payors in the U.S. or elsewhere, deny reimbursement for our products, limit the indications for which our products will be reimbursed, are unclear on appropriate reimbursement codes or provide reimbursement only on unfavorable terms. For example, in June 2023 five MACs, which set physician fee payment rates for products covered by temporary CPT Category III codes, published proposed local coverage determinations (LCDs) that deemed certain ophthalmic procedures, including the procedures using our iAccess and iPRIME products, investigational and therefore not covered by Medicare and not reimbursed, which LCD was ultimately adopted and then reversed by these MACs. Also, when procedures associated with our products transition from temporary CPT Category III codes to permanent CPT Category I codes, the physician and facility reimbursement levels associated with the procedures using these products could be decreased, such as the decreased payment rates for procedures using our iStent-related products, in conjunction with cataract surgery, established by CMS for 2022 and 2023, as discussed above. Even when a permanent billing code has been assigned to a product, there is no guarantee that coverage will be provided. If we are unable to maintain our existing codes or obtain new permanent codes for procedures using our products, use existing codes for new products or obtain new reimbursement codes for our products in development, we may be subject to significant pricing pressure, that could harm our results of operations, financial condition and prospects. In the foreign markets in which we operate, different pricing and reimbursement systems, could result in lower reimbursement, harming our ability to operate our business.

We cannot predict to what extent current global economic conditions may disrupt healthcare systems and access to our products or result in a widespread loss of individual health insurance coverage due to unemployment, a shift from commercial payor coverage to government payor coverage, or an increase in demand for patient assistance or free drug programs, any of which could adversely affect our net revenue. In addition, payers consistently engage in cost containment efforts, which could result in decreased reimbursement levels for prescription drugs and the imposition of prior authorization for the use of our products. We cannot predict actions that third party payors may take, including limiting access to or the level of reimbursement for our products or refusal to provide any approvals or coverage.

Risks Related to Our Intellectual Property

If we are unable to adequately protect our intellectual property, our competitors and other third parties could develop and commercialize products similar or identical to ours, which would substantially impair our ability to compete.

Our success and ability to compete depends significantly upon our ability to obtain, maintain and protect our proprietary rights and licensed intellectual property rights to the technologies and inventions used in or embodied by our products. We rely on a combination of patents and trademark rights, and to a lesser extent on trade secrets and copyrights, together with licenses and nondisclosure agreements to protect our technologies. These legal means, however, afford only limited protection and may not adequately protect our business. We also have not pursued or maintained, and may not pursue or maintain in the future, patent protection for our products in every country or territory in which we sell or will in the future sell our products. In addition, we cannot be sure that any of our pending patent applications or pending trademark applications will issue or issue in a form that will be advantageous to us.

Despite our efforts, we cannot guarantee that we will be able to adequately protect our proprietary rights, which could substantially impair our ability to compete. Our patents may be challenged and held invalid or we may be unable to extend the protection on products with expiring patents. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. Competitors could purchase our products and attempt to replicate some or all of the competitive advantages we derive from our development efforts, infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside of our intellectual property rights. Further, although it is our policy to require each of our employees, consultants and any other parties who may be involved in the development of intellectual property on our behalf to execute proprietary information and inventions agreements, we may be unsuccessful in doing so with each party who in fact develops intellectual property that we regard as our own. The relevant assignment provisions may not be self-executing or may be breached, resulting in ownership disputes and/or litigation.

We have many foreign patents and patent applications, and expect to pursue patent protection in the most significant markets in which we do business. The laws of other countries in which our products are or may be sold may not protect our product offerings and intellectual property to the same extent as U.S. laws, if at all. Many companies

Table of Contents

have encountered significant difficulties in obtaining, protecting and defending such rights in international markets. In addition, many countries limit the enforceability of patents against other parties, including government agencies or government contractors. In these countries, the patent owner may have limited remedies, and certain countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to other parties. We also may be unable to protect our rights in trade secrets and unpatented proprietary technology in these countries. If we encounter such difficulties or are otherwise precluded from effectively protecting our intellectual property rights in these countries, our business, financial condition and results of operations could be substantially harmed.

We may not be able to accurately estimate or control our future operating expenses in relation to obtaining, enforcing and/or defending intellectual property, which could lead to cash shortfalls. Our operating expenses may fluctuate significantly in the future as a result of the costs of preparing, filing, prosecuting, defending and enforcing patent claims and other patent related costs, including litigation costs and the results of such litigation or costs associated with administrative proceedings and the results of such proceedings.

We have been and may in the future become involved in patent and other intellectual property litigation or administrative proceedings relating to our intellectual property rights, which could be costly, time consuming and unsuccessful and could interfere with our ability to successfully commercialize our products.

Intellectual property rights are essential to our business. We have asserted and may in the future need to assert claims of infringement against third parties to protect our rights, or to invalidate or challenge the intellectual property rights of a third party, including those rights owned by our competitors. Additionally, third parties could assert infringement or misappropriation claims against us with respect to our current or future commercial products and seek to invalidate one or more of our patents or trademarks. Such claims could arise in situations where certain employees, consultants or contractors were previously, or are currently, employed by other medical device, biotechnology or pharmaceutical companies, including our competitors or potential competitors; we may be subject to claims that we or these individuals have, inadvertently or otherwise, misappropriated the intellectual property or disclosed the alleged trade secrets or other proprietary information, of these other employers.

There is no guarantee that we would be successful enforcing or defending our intellectual property rights in court. A court could hold that some or all of our asserted intellectual property rights are not infringed, or could invalidate our rights, hold our rights unenforceable, or substantially narrow the scope of protection. Further, we could be prohibited from manufacturing or selling our products or a court could order us to pay substantial compensatory damages as well as other penalties and fines. Any such adverse result would undermine our competitive position. Regardless of the final outcome, any litigation to enforce our intellectual property rights in patents, copyrights, trade secrets or trademarks is highly unpredictable and could result in substantial costs and diversion of resources, which could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Our Common Stock

Anti-takeover provisions in our Charter and Bylaws and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

Provisions in our Restated Certificate of Incorporation (Charter) and amended and restated bylaws (Bylaws) may have the effect of delaying or preventing a change of control or changes in our management. Our Charter and Bylaws include provisions that:

●

authorize our board of directors to issue, without further action by the stockholders, up to 5,000,000 shares of undesignated preferred stock;

●

require that any action to be taken by our stockholders be affected at a duly called annual or special meeting and not by written consent;

●

specify that special meetings of our stockholders may be called only by our board of directors, the chairman of the board of directors, the chief executive officer or the president;

●

establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

●

divide our board of directors into three classes, with each class serving staggered three year terms;

●

provide that our directors may be removed only for cause by a supermajority vote of our stockholders;
