Notes to Consolidated Financial Statements
Note 1. The Company and Nature of Business
Description of Business
Sight Sciences, Inc. (the “Company”) was incorporated in the State of Delaware in 2010 and is headquartered in Menlo Park, California. The Company is an ophthalmic medical device company focused on the development and commercialization of surgical and nonsurgical technologies for the treatment of prevalent eye diseases. The Company’s mission is to develop transformative, interventional technologies that allow eyecare providers to procedurally elevate the standards of care — empowering people to keep seeing.
The Company's product portfolio aligns with its two reportable operating segments: Interventional Glaucoma and Interventional Dry Eye. The products for the Interventional Glaucoma segment consist of the OMNI® Surgical System family of products ("OMNI") and the SION® Surgical Instrument ("SION"). The Company’s commercial OMNI offerings, consisting of the Ergo Series of the OMNI Surgical System ("OMNI Ergo") and the OMNI EDGE Surgical System ("OMNI EDGE") are implant-free, minimally invasive glaucoma surgery technologies. OMNI Ergo and OMNI EDGE are indicated in the United States to reduce intraocular pressure in adult patients with primary open-angle glaucoma. The OMNI Ergo is CE Marked for the catheterization and transluminal viscodilation of Schlemm’s canal and cutting of the trabecular meshwork to reduce intraocular pressure in adult patients with open-angle glaucoma. SION is a bladeless, manually operated device used in ophthalmic surgical procedures to excise trabecular meshwork. The product portfolio for the Interventional Dry Eye segment consists of the TearCare® System ("TearCare") for ophthalmologists and optometrists. TearCare is a proprietary, interventional, dry eye device designed to melt and facilitate the comprehensive removal of meibomian gland obstructions and restore gland functionality and healthy oil production for adult patients with evaporative dry eye disease due to meibomian gland disease when used in conjunction with manual expression of the meibomian glands, enabling clearance of gland obstructions by physicians to address the leading cause of dry eye disease.
Liquidity Considerations
Since inception, the Company has incurred losses and negative cash flows from operations. As of December 31, 2025, the Company had an accumulated deficit of $384.7 million and recorded a net loss of $38.4 million for the year then ended and expects to incur additional losses in the future.
The Company believes its cash and cash equivalents balance, and other existing sources of liquidity will satisfy its working capital and capital resource requirements for at least 12 months from the date of issuance of its consolidated financial statements. Any failure to generate increased revenue, achieve improved gross profit, or control operating costs could require the Company to raise additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all. If the Company is unable to improve its financial performance, or to secure additional funding when desired, it may need to delay the development of its products, reduce research and development activities, modify or abandon planned future expenditures, or reduce operating costs. Any of these actions could harm the Company’s business, requiring it to change its business strategy, scale back its operations, or limit its ability to achieve its strategic objectives.
Note 2. Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). The Company’s consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Sight Sciences UK, Ltd and Sight Sciences GmbH. All intercompany balances and transactions have been eliminated in consolidation.
Presentation Reclassification
Certain prior year amounts have been reclassified for consistency with current year presentation. This reclassification was to report withholding taxes on net share settlement of restricted stock units as a deduction to the issuance of common stock upon vesting of restricted stock units in the consolidated statements of stockholders’ equity. This reclassification had no effect on the reported results of operations.
Use of Estimates
The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expense during the reporting period. The most significant estimates relate to the allowance for credit losses, inventory excess and obsolescence, the selection of useful lives of property and equipment, determination of the fair value of stock option grants, and provisions for income taxes and contingencies. Management evaluates its estimates and assumptions on an ongoing basis using historical experience, an assessment of current and anticipated future macroeconomic conditions, authoritative accounting guidance, and other factors management believes to be reasonable, and makes adjustments when facts and circumstances dictate. These estimates are based on information available as of the date of the financial statements. To the extent there are differences between these estimates and actual results it could result in a material effect on the Company’s financial condition, results of operations and liquidity.
Fair Value of Financial Instruments
The Company’s financial instruments typically consist of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued and other current liabilities, common stock warrants, and short-term and long-term debt. The Company's cash equivalents are comprised of U.S. treasury securities that are classified as held-to-maturity and recorded at amortized cost in the financial statements, and money market accounts. The Company records accounts receivable, accounts payable, and accrued and other current liabilities at their carrying value, which approximates fair value due to the short time to the expected receipt or payment. The carrying amount of the Company’s debt approximates its fair value as the effective interest rate approximates market rates currently available to the Company.
Concentration of Credit and Supply Chain Risk
Financial instruments that subject the Company to concentration of credit risk consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are deposited with a high-quality financial institution. Deposits at this institution may, at times, exceed federally insured limits. Management believes that this financial institution is financially sound and that minimal credit risk exists with respect to these deposits. The Company has not experienced any losses on its deposits of cash and cash equivalents.
The Company relies on third-party contract manufacturers for the manufacture of all of its commercial products. The Company also depends on a limited number of single source suppliers to provide some of the components, accessories and materials used in the manufacture and assembly of its commercial products. Any failure on the part of the Company’s manufacturers or suppliers to timely provide products or components to the Company, or any other disruptions in the Company’s supply chain, would have a negative impact on the Company’s financial condition, results of operations and liquidity.
For the years ended December 31, 2025 and 2024, there wereno customers that represented 10% or more of the Company's revenue or accounts receivable.
Cash and Cash Equivalents and Restricted Cash
The Company considers all highly liquid investments with an original maturity of 90 days or less, when purchased, to be cash and cash equivalents. Cash and cash equivalents include U.S. treasury securities that are classified as held-to-maturity and recorded at amortized cost in the financial statements. The remainder of cash and cash equivalents consists of checking and savings deposits, as well as money market funds, recorded at cost, which approximates fair value.
The Company also has restricted cash balances, which consist of checking and savings deposits, recorded at cost, which approximates fair value. These restricted cash balances are held as collateral in conjunction with the Company’s corporate credit card program. As of December 31, 2025, the Company had $0.3 million in restricted cash, which is recorded in prepaid and other current assets in the Company’s consolidated balance sheets.
Accounts Receivable and Provision for Credit Losses
Accounts receivable are stated at invoiced amounts, net of estimated allowance for credit losses. The Company’s provision for credit losses methodology for accounts receivables is developed using its historical collection experience, current and anticipated future macroeconomic conditions, and a review of the current aging status and financial condition of its customers. The Company uses its reasonable judgment, based on the available information, and records a provision against amounts due to reduce the receivable to the amount that is expected to be collected. These specific provisions are reevaluated and adjusted as additional information is received that impacts the amount reserved. To date, the Company has not experienced material credit-related losses. The allowance for credit losses was $0.2 million and $0.7 million as of December 31, 2025 and 2024, respectively.
Inventory, net
Inventory represents raw materials and finished goods purchased from third-party suppliers and manufacturers. Inventory is valued at the lower of cost or net realizable value. Cost is determined using actual costs on a first-in, first-out basis for all inventory. Net realizable value is determined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. As of December 31, 2025, the Company’s inventory balance consisted of finished goods of $6.8 million and raw materials of $1.2 million. As of December 31, 2024, the Company’s inventory consisted of finished goods of $5.6 million and raw materials of $1.0 million.
The Company regularly reviews inventory quantities in consideration of its actual inventory loss experiences, projected future demand for its products, and remaining shelf life to record a provision for excess and obsolete inventory when appropriate. The Company’s policy is to write down inventory that has become obsolete, inventory that has a cost basis in excess of the lower of cost or expected net realizable value, and inventory in excess of expected product demand. The estimate of excess quantities requires the Company to exercise judgment and is primarily dependent on the Company’s estimates of future demand for the particular product. As of December 31, 2025 and 2024, the Company had reserves for excess and obsolete inventory of $0.3 million and $0.3 million.
Property and Equipment, net
Property and equipment are recorded at cost, less accumulated depreciation. Repairs and maintenance costs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, typically two to five years. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheets and any resulting gain or loss is reflected in the consolidated statements of operations and consolidated loss in the period realized.
Construction-in-process assets consist primarily of tools and equipment used to manufacture the Company’s products that have not yet been placed in service. These assets are stated at cost and are not initially depreciated. Once the assets are placed into service, assets are reclassified to the appropriate asset class based on their nature, and are depreciated in accordance with their respective useful lives as indicated above.
Impairment of Long-Lived Assets
The Company assesses long-lived assets, including property and equipment, whenever events or changes in business circumstances indicate that the carrying amount of such assets may not be fully recoverable. If indicators of impairment exist, an impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition are less than their carrying amount. Impairment, if any, is measured as the amount by which the carrying amount of the long-lived assets exceeds their fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. The Company didnot record any impairment of long-lived assets for the years ended December 31, 2025 and 2024.
Leases
Contractual arrangements that meet the definition of a lease are classified as operating or finance leases and are recorded on the consolidated balance sheets as both a right-of-use asset (“ROU asset”) and lease liability, calculated by discounting fixed lease payments over the lease term at the Company’s incremental borrowing rate (“IBR”). Lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company currently does not have any finance leases. The Company has various operating leases, which include facility leases and equipment leases.
As the implicit rates for the Company's operating leases are not determinable, the Company uses an IBR based on the information available at the respective lease commencement dates to determine the present value of future payments. IBR represents the interest rate that the Company would expect to incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis with similar terms and payments, in an economic environment where the leased asset is located.
The Company does not recognize lease ROU assets or lease liabilities for short-term leases, if any, having initial terms of 12 months or less at lease commencement as an accounting policy election. In determining the lease term, the Company includesall renewal options that are reasonably probable to be executed. The Company recognizes rent expense on a straight-line basis over the lease term for these short-term leases.
Common Stock Warrants
The common stock warrants issued by the Company pursuant to the Hercules Loan Agreement (as defined in Note 5. Debt) are classified in equity, as they meet all the criteria for equity classification. The fair value of the common stock warrants was calculated using the Black-Scholes option pricing method and are recorded at fair value upon issuance in additional paid-in capital in the consolidated balance sheets. These common stock warrants are not remeasured after the issuance date.
The Company’s unissued common stock warrants under the Hercules Loan Agreement are classified as liabilities in the consolidated balance sheets. These common stock warrants are remeasured at each reporting date using the Black-Scholes option pricing method, with the gain or loss recorded in the Company’s consolidated statements of operations and comprehensive loss.
See Note 5. Debt and Note 7. Stockholders' Equity, for additional information regarding the common stock warrants.
Revenue Recognition
The Company applies the following five steps to determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its arrangements:
Identify the contract with a customer,
Identify the performance obligations in the contract,
Determine the transaction price,
Allocate the transaction price to performance obligations in the contract, and
Recognize revenue as the performance obligations are satisfied.
Revenue recognized during the years ended December 31, 2025 and 2024 relates entirely to the sale of the Company’s products within the Interventional Glaucoma and Interventional Dry Eye segments. These sales are primarily to hospitals, medical centers, and eyecare professionals ("ECPs") throughout the United States. Sales are generally made through sales representatives and distributors.
The Company’s revenue arrangements consist of a single performance obligation. Revenue is recognized at the point in time when control of the promised goods transfer to the Company’s customers. Revenue is measured at the amount of consideration expected to be received in exchange for the transfer of goods. The amount of revenue that is recognized is based on the transaction price, which represents the invoiced amounts and includes estimates of variable consideration, such as discounts or rebates, where applicable. The Company does not offer right of return, except in the case where items are defective as manufactured, and the Company does not typically provide customers with a right to a refund. The amount of variable consideration included in the transaction price may be constrained and is included only to the extent it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Payment terms, typically 30 days, are offered to customers and do not include a significant financing component. The Company extends credit to customers based upon their financial condition and credit history and generally requires no collateral. The Company does not have any contract balances related to product sales.
Shipping and handling costs incurred for the delivery of goods to customers are included in cost of goods sold. In cases where the Company bills shipping and handling costs to customers, the Company classifies those amounts in net revenue. As a practical expedient, the Company recognizes the incremental costs of obtaining contracts, such as sales commissions, as an expense when incurred since the amortization period of the asset the Company otherwise would have recognized is one year or less. Sales commissions are recorded within selling, general and administrative expenses in the consolidated statements of operations and comprehensive loss.
Cost of Goods Sold
The Company purchases products, components, accessories, and materials from third-party suppliers and manufacturers. Cost of goods sold consists primarily of costs related to materials, manufacturing overhead costs, reserves for excess, and obsolete and non-sellable inventories. Cost of goods sold also includes depreciation expense for production equipment and certain direct costs, such as shipping and handling costs.
Research and Development
The Company expenses research and development costs as incurred. Research and development expenses consist primarily of product development, clinical studies to develop and support the Company’s products, regulatory expenses, medical affairs, and other costs associated with products and technologies that are in development. Research and development expenses include employee compensation (including stock-based compensation), supplies, consulting, prototyping, testing, materials, travel expenses, depreciation, and an allocation of facility overhead expenses.
Selling, General and Administrative
Selling, general and administrative expenses include compensation (including stock-based compensation) and employee benefits for executive management, commercial, finance, and human resources personnel; facility costs (including rent); bad debt costs; professional service fees; and other general overhead costs, including depreciation.
Advertising Expense
The Company expenses advertising costs as incurred. Advertising expenses for fiscal years 2025 and 2024 were $2.4 million and $1.4 million, respectively, included in selling, general and administrative expenses in the consolidated statements of operations and comprehensive loss.
The Company's equity incentive plan permits the grant of stock-based awards, such as stock options and restricted stock units ("RSUs"), to employees, directors and consultants. The Company’s employee stock purchase plan (“ESPP”) allows employees to purchase stock from the Company at a discount. The Company measures and records the expense related to stock-based payment awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, which is generally equal to the vesting period and uses the straight- line method to recognize stock-based compensation, and accounts for forfeitures as they occur.
The Company selected the Black-Scholes option-pricing model as the method for determining the estimated fair value for stock options and awards granted pursuant to the ESPP. The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions, which determine the fair value of share-based awards, including the stock option’s expected term, expected volatility of the underlying stock, risk-free interest rate and expected dividend yield. The Company uses the simplified method for determining the expected term of the granted stock options since there is not adequate historical data to utilize in calculating the expected term
The fair value of RSU awards is determined based on the number of units granted and the closing price of the Company's common stock as of the grant date.
Interest Expense
The Company’s interest expense consists primarily of interest incurred on our outstanding indebtedness. The Company's interest expense also includes non-cash interest related to the accretion of debt discount and debt issuance costs, as well as the accrual of the final fee due at maturity.
Investment Income
The Company’s investment income consists primarily of interest and amortization on held-to-maturity investments in treasury securities. All treasury securities are purchased with maturities of less than 90 days and recorded at amortized costs in the financial statements.
Currency Remeasurement
Foreign currency transaction gains and losses are recorded in other income (expense), net in the Company’s consolidated statements of operations and comprehensive loss. Such amounts have not been material for all periods presented.
Income Taxes
The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Management assesses the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all off a deferred tax asset will not be realized. Due to the Company's historical operating performance and the recorded cumulative net losses in prior fiscal periods, the net deferred tax assets have been fully offset by a valuation allowance.
The Company recognizes uncertain income tax positions at the largest amount that is more likely than not to be sustained upon audit by relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Changes in recognition or measurement are reflected in the period in which judgment occurs. The Company's policy is to recognize interest and penalties related to the underpayment of income tax as a component of provision for income taxes.
Comprehensive Loss
Comprehensive loss represents all changes in stockholders’ equity except those resulting from distributions to stockholders. There have been no items qualifying as other comprehensive income (loss) and, therefore, for all periods presented, there was no difference between comprehensive loss and the Company’s reported net loss.
Net Loss Per Share Attributable to Common Stockholders
Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Basic and diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period without consideration of potentially dilutive securities. The Company’s potentially dilutive shares, which consist of outstanding common stock options and RSUs, were excluded in the computation of diluted net loss per share for the period as the result would have been anti-dilutive due to the Company's net loss position in each period.
Restructuring Expense
Restructuring expenses may arise from targeted plans to reduce operating expenses, improve cost efficiencies, and better align our operating structure for long-term, profitable growth, and primarily include one-time employee severance and benefits contribution costs. For one-time termination benefits, expense is recorded when employees are entitled to receive those benefits and amounts can be reasonably estimated. Restructuring expenses are recorded as an operating expense in the consolidated statements of operations and comprehensive loss.
Emerging Growth Company and Smaller Reporting Company
The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as well as a "smaller reporting company, as defined by the Securities and Exchange Commission per Rule 12b-2 of the Exchange Act. As such the Company is eligible for exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies or smaller reporting companies, including reduced reporting and extended transition periods to comply with new or revised accounting standards for public business entities. The Company has elected to avail itself of this exemption and, therefore, is not subject to the timeline for adopting new or revised accounting standards for public business entities that are not emerging growth companies, and will follow the applicable transition guidance.
Recent Accounting Pronouncements
Accounting Standards Adopted
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU includes amendments requiring enhanced income tax disclosures, primarily related to standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The Company adopted the standard on January 1, 2025, and elected to apply the standard on a prospective basis for fiscal year reporting. The adoption resulted in the expanded presentation of the Company’s effective tax rate reconciliation and the disaggregation of income taxes paid in our financial statement footnotes. The application of these disclosure requirements had no impact on our consolidated balance sheets, consolidated statements of operations and comprehensive loss, and consolidated cash flow statements. The information is presented in Note 10: Income Taxes.
In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This ASU allows the Company to elect a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset when developing reasonable and supportable forecasts as part of estimating expected credit losses. The Company adopted the standard for the year end December 31, 2025 for fiscal year reporting. The standard is to be applied on a prospective basis. The standard did not have an impact on the Company’s current credit loss measurement process, and thus no material impact on the Company’s financial results.
Accounting Standards Not Yet Adopted
In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures. The ASU requires additional disclosure in the notes the financial statements of specified information about certain expenses such as purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depreciation and other expenses which are presented in the face of the income statement within continuing operations. This ASU is effective for annual periods beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this new standard will have on the related disclosures in the consolidated financial statements.
In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350): Targeted Improvements to the Accounting for Internal-Use Software. This ASU modifies the criteria for when software costs may be capitalized by eliminating consideration of software project development stages and by enhancing guidance for the "probable-to-complete" threshold. This ASU is effective for our annual reports beginning in 2028, and interim periods within those annual reporting periods. Early adoption of this ASU is permitted. We are currently evaluating the impact that adoption of this ASU may have on our financial statements and disclosures.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impact of adopting this standard and does not expect it to have a material impact on its financial statements.
As of December 31, 2025, there are no additional ASUs issued and not yet adopted that are expected to have a material impact on the Company's financial statements and related disclosures.
Note 3. Fair Value Measurements
The Company reports all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1—Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.
Level 3—Inputs are unobservable inputs for the asset or liability. The level in the fair value hierarchy within which a fair value measurement in its entirety is based on the lowest-level input that is significant to the fair value measurement in its entirety.
The following tables set forth by level within the fair value hierarchy our assets and liabilities that are measured on a recurring basis and reported at fair value as of December 31, 2025 and 2024.

The Company measures the fair value of outstanding debt for disclosure purposes on a recurring basis. As of December 31, 2025 and 2024, total debt of $40.3 million and $39.4 million is reported at amortized cost, respectively. This outstanding debt is classified as Level 2 as it is not actively traded. The amortized cost of the outstanding debt approximates the fair value.
The Company measures the fair value of the unissued common stock warrants that may be issued pursuant to the Hercules Loan Agreement (as defined in Note 5, Debt) using the Black-Scholes option pricing method. See Note 5, Debt, and Note 7, Stockholders' Equity, for additional information regarding the common stock warrants.
The financial statements as of December 31, 2025 and 2024, do not include any assets or liabilities that are measured at fair value on a nonrecurring basis.

Note 5. Debt
Hercules Capital Loan Agreement
In January 2024, the Company entered into a Loan and Security Agreement (the "Hercules Loan Agreement") with Hercules Capital, Inc ("Hercules") and certain of its affiliates (collectively with Hercules, the "Lenders"), which provides for a maximum $65.0 million credit facility. An initial tranche of $35.0 million (the “Initial Loan”) was funded under the Hercules Loan Agreement on January 22, 2024, which was used to discharge the Company's indebtedness under its prior secured credit facility (the "Prior Loan Agreement") with its prior lenders. On December 10, 2024, the Company consummated the drawdown of the $5.0 million Tranche I(b) Term Loan Advance (the "Tranche I(b) Loan") under the Hercules Loan Agreement. Upon consummation of the Tranche I(b) Loan, the aggregate principal amount of borrowings under the Hercules Loan Agreement was $40.0 million.
In addition to the Initial Loan and the Tranche 1(b) Loan, the Hercules Loan Agreement provides additional tranches available to the Company (the “Tranche Loans,” and together with the Initial Loan and the Tranche I(b) Loan, the “Term Loans"). Tranche 2 originally consisted of $10.0 million available to draw through September 15, 2025, contingent upon the achievement of certain performance milestones prior to June 30, 2025 which were not met and thus Tranche 2 was not available to the Company. Tranche 3 consisted of $15.0 million available to draw through the interest only period in increments of $5.0 million, subject to the sole approval of Hercules' investment committee.
The Hercules Loan Agreement originally provided for a maturity date of July 1, 2028, with an interest only period running for the first 30 months of the agreement term, extendable for an additional six months for a total of 36 months upon the achievement of certain performance milestones prior to June 30, 2025. These performance milestones were not met by the June 30, 2025 deadline, and thus the six-month extension of the interest only period was not available to the Company.
In September 2025, the Company and Hercules entered into a third amendment (the “Amendment”) to the Hercules Loan Agreement, pursuant to which the expiration of the interest-only period under the agreement was extended by an additional six-months, from August 1, 2026 to February 1, 2027. The Amendment also amended the Hercules Loan Agreement to reallocate an undrawn and unavailable $10.0 million tranche by increasing the amount available to draw through the interest only period from $15.0 million to $25.0 million in minimum increments of $5.0 million, subject to the sole approval of Hercules’ investment committee, maintaining the maximum $65.0 million credit facility.
The Term Loans accrue interest at a floating annual rate equal to the greater of 10.35% or the Wall Street Journal prime rate plus 2.35%, with the interest rate equal to 10.35% at December 31, 2025. The final payment fee is set at 5.95% of the funded balance, which is recognized as a debt discount and is being accreted into the amortization of debt issuance costs using the effective interest rate method over the term of the loan.
In conjunction with the funding of the Initial Loan, the Company issued warrants to the Lenders to purchase up to an aggregate of 135,686 shares of its common stock at an exercise price of $5.159 per share, which were recorded and classified as equity. On December 10, 2024, upon the funding of the Tranche I(b) Loan, the Company issued additional warrants to the Lenders to purchase 26,095 shares of its common stock at an exercise price of $3.83 per share. Each warrant is exercisable for a period of seven years from the date of issuance. If the additional Term Loans are funded, the Company will be obligated to issue to the Lenders additional warrants to purchase common stock in an amount equal to 2.0% of the funded balance of each tranche loan under the Hercules Loan Agreement, divided by the exercise price on the date the Company draws funds under such tranche loan. The exercise price will be calculated using the five-day volume-weighted average stock price as of such date. See Note 7, Stockholders' Equity, for additional information regarding these common stock warrants.
The obligations under the Hercules Loan Agreement are guaranteed by the Company and its future subsidiaries, subject to exceptions for certain foreign subsidiaries. The obligations under the agreement are secured by substantially all of the Company's assets, including its material intellectual property. Additionally, the Company is subject to customary affirmative and negative covenants, including covenants that limit or restrict the ability of the Company to, among other things, incur indebtedness, grant liens, merge or consolidate, make investments, dispose of assets, make acquisitions, pay dividends or make distributions, repurchase stock and enter into certain transactions with affiliates, in each case subject to certain exceptions. The Company is also subject to certain minimum cash and revenue covenants under the Hercules Loan Agreement. The Company was in compliance with all covenants as of December 31, 2025.
While any Term Loans remain outstanding under the Hercules Loan Agreement, the Company is required to use commercially reasonable efforts to grant to the Lenders the option to invest up to $3.0 million in the Company’s next round of equity financing, if any, that is broadly marketed to multiple investors on the same terms, conditions and pricing offered to investors in such subsequent equity financing.

Note 6. Commitments and Contingencies
Operating Lease Obligations
The Company leases its corporate headquarters in Menlo Park, California. The lease commenced in August 2021, and the Company has since signed two amendments to extend the term of the lease. The second amendment, executed in January 2026, extended the lease term from November of 2026 until December of 2028. The lease ROU asset and corresponding lease liability were estimated using a weighted-average incremental borrowing rate (“IBR”) of 11.40%. Total base rent for the amended 26 months under the amended lease agreement is approximately $1.1 million.
As of December 31, 2025, the weighted average remaining lease term for the Company's leases was 0.8 years.

Legal Proceedings
On September 16, 2021, the Company filed suit in the U.S. District Court for the District of Delaware (C.A. No. 1:21-cv-01317) (the “Court”) alleging that Ivantis, Inc. (“Ivantis”) directly and indirectly infringes the Company’s U.S. Patent Nos. 8,287,482, 9,370,443, 9,486,361, and 10,314,742 by making, using, selling, and offering for sale the Hydrus® Microstent. The Company’s complaint seeks money damages and injunctive relief. On January 24, 2022, Ivantis asserted counterclaims requesting declaratory judgments that the Company's asserted patents-in-suit are not infringed and/or invalid. On August 1, 2022, the Company filed an amended complaint alleging that Alcon Inc., Alcon Vision, LLC and Alcon Research, LLC (collectively, “Alcon”) infringe the four originally asserted patents by making, using, selling, and offering for sale the Hydrus® Microstent, and that all defendants also infringe U.S. Patent No. 11,389,328. The defendants asserted counterclaims requesting declaratory judgments that the Company’s asserted patents-in-suit are not infringed and/or are invalid. In September 2022, Ivantis and Alcon filed petitions with the U.S. Patent and Trademark Office (“USPTO”) seeking inter partes review of U.S. Patent Nos. 8,287,482, 9,370,443, 9,486,361, and 10,314,742 (IPR2022-01529, IPR2022-01530, IPR2022-01533, IPR2022-01540), each of which the USPTO denied for raising prior art references and invalidity arguments that were cumulative of those previously considered by the USPTO. On April 26, 2024, at the conclusion of a five-day jury trial, the Company was awarded a positive jury trial verdict of $34 million, comprised of $5.5 million in lost profits damages and $28.5 million in royalty damages for commercial sales of the Hydrus® Microstent for the period between its commercial launch through trial. The patents at issue were U.S. Patent Nos. 8,287,482, 9,370,443, and 11,389,328. In December 2024, the Court heard oral arguments on the parties’ post-trial briefings at the conclusion of which, the Court ordered the parties to engage in non-binding mediation. In March 2025, the Company and Alcon informed the Court that the dispute had not been resolved through mediation and asked the Court to rule on the parties’ post-trial motions and enter a judgement. The judgment has not yet been entered and, once entered, it will be subject to appeal.
In June 2025, Alcon filed petitions with the USPTO for ex parte reexaminations challenging the validity of each of the three patents asserted by the Company at trial, based on prior art patents and publications. The USPTO has granted Alcon’s requests to initiate the reexaminations. It is possible that the April 2024 jury verdict in the Company’s favor, including its ability to collect past damages and ongoing royalties, may be materially and adversely impacted if the reexamination proceedings result in final, non-appealable judgments of invalidity of the asserted claims of the patents-in-suit before a final, non-appealable judgment is entered by the Court in the patent infringement litigation or if the asserted claims are amended during the reexamination proceedings. For example, entry of such judgments of invalidity by the USPTO could include vacating the jury verdict and a finding that the patents-in-suit are invalid. The Company is presently unable to predict the outcome of this lawsuit or the ex parte reexamination proceedings or to reasonably estimate the potential financial impact of the lawsuit or ex parte reexamination proceedings.
In addition to the foregoing, from time to time, the Company is subject to legal claims, regulatory matters and contingencies in the ordinary course of business. Accruals for these matters are reflected in the financial statements based on management’s assessment, including the advice of legal counsel, of the expected outcome of these matters. Liabilities for estimated losses are accrued if the potential losses from any legal proceedings, regulatory matters or contingencies are considered probable and the amounts can be reasonably estimated. Significant judgment is required in both the determination of probability of loss and the determination as to whether the amount of loss can be reasonably estimated. Accruals are based only on information available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, management reassesses potential liabilities related to legal claims, regulatory matters and contingencies, and may revise its previous estimates, which could materially affect the Company’s results of operations in a given period.
Except as described above, as of December 31, 2025 the Company was not a party to any legal proceedings, regulatory matters, or other disputes or claims which, if determined adversely, it believes would, individually or taken together, have a material adverse effect on the Company’s business, financial condition, operating results, liquidity, or future prospects.
Indemnification
In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.
The Company indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits, while the director is or was serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The term of the indemnification period lasts as long as a director or officer may be subject to any proceeding arising out of acts or omissions of such director or officer in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds director and officer liability insurance. This insurance allows the transfer of risk associated with the Company’s exposure and may enable it to recover a portion of any future amounts paid. The Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to these obligations as of December 31, 2025 and 2024.
Strategic Reduction in Force Initiative
In August of 2025, the Company implemented a targeted plan, intended to reduce operating expenses, improve cost efficiencies, and better align its operating structure for long-term profitability growth. In connection with the targeted plan, the Company restructured its global workforce in order to reduce operating expenses. Approximately 45% of the employees impacted were in general and administrative functions. The remaining employees were split between research and development and clinical functions, as well as employees in sales and sales management functions.
In conjunction with the execution of the targeted plan, the Company incurred approximately $2.8 million of expense in the third quarter of 2025. The Company does not anticipate incurring any additional costs in execution of the targeted plan. Of this amount, $1.8 million is recorded in selling, general and administrative expenses, with $1.0 million recorded in research and development expenses. The expense consists mostly of one-time severance and benefits contribution costs. In addition, the Company recorded a non-cash reversal in stock-based compensation cost of $0.6 million in the third quarter of 2025. As of December 31, 2025, $0.7 million is recorded in accrued expenses for estimated costs incurred with the execution of the plan. The remaining costs will be paid to impacted employees through August 31, 2026.
Note 7. Stockholders' Equity
Common Stock
The Company’s certificate of incorporation provides for 200,000,000 authorized shares of common stock, par value $0.001 per share, and 10,000,000 authorized shares of preferred stock, par value $0.001 per share. The holders of common stock are entitled to receive dividends whenever funds are legally available, when and if declared by the board of directors. As of December 31, 2025, no dividends have been declared. Each share of common stock is entitled toone vote.
At December 31, 2025 and 2024, the Company had reserved common stock for future issuances as follows:
| December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Common stock available for future grant | 7,876,575 | 5,931,302 |
| Common stock options issued and outstanding | 3,063,476 | 4,464,388 |
| Restricted stock units outstanding | 4,048,888 | 4,341,818 |
| Shares available for future purchase under ESPP | 1,880,211 | 1,631,076 |
| Common stock reserved for issuance upon exercise of outstanding warrants | 161,783 | — |
| 17,030,933 | 16,368,584 | |
Common Stock Warrants
On January 22, 2024, in conjunction with the funding of the Initial Loan under the Hercules Loan Agreement, the Company issued common stock warrants to the Lenders to purchase up to an aggregate of 135,686 shares of its common stock at an exercise price of $5.159 per share. On December 10, 2024, upon the funding of the Tranche I(b) Loan, the Company issued additional warrants to the Lenders to purchase 26,095 shares of its common stock at an exercise price of $3.83 per share. Each warrant is exercisable for up to seven years from the date of issuance. During the year ended December 31, 2024, the fair value of the issued warrants recorded was $0.7 million.
If the additional Term Loans are funded, the Company will be obligated to issue to the Lenders additional warrants to purchase common stock in an amount equal to 2.0% of the funded balance of each tranche loan, divided by the exercise price on the date the Company draws funds under such tranche loan, which is referred to as the issuance date. The exercise price will be calculated using the five-day volume-weighted average stock price as of the issuance date.
The unissued warrants do not meet the requirements for classification as equity and are recorded as other noncurrent liabilities in the consolidated financial statements. As of both December 31, 2025 and 2024, the fair value of the unissued warrants recorded was less than $0.1 million.
Note 8. Equity Incentive Plans
2011 Stock Option Plan and 2021 Equity Incentive Plan
In 2011, the Company approved the 2011 Stock Option Plan (the “2011 Plan”) that provided for the grant of stock options to employees and nonemployees of the Company.
In July 2021, the board of directors and stockholders adopted and approved the 2021 Incentive Award Plan, (the “2021 Plan”). Under the 2021 Plan, the Company has the ability to issue incentive stock options ("ISOs"), nonqualified stock options ("NSOs"), stock appreciation rights, dividend equivalent rights, restricted stock awards, and restricted stock units ("RSUs").
Stock options under the 2021 Plan can typically be granted for periods of up to ten years. For stock options granted to a grantee who, at the time the option is granted, owned stock representing more than 10% of the voting power of all classes of stock of the Company (or any parent or subsidiary of the Company), the term may be up to five years. The ISOs and NSOs are granted at a price per share not less than the fair value at the date of grant. The exercise price of a stock option granted to a 10% stockholder shall be not less than 110% of the grant date fair value of the shares. Stock options granted to new hires generally vest over a four-year period, with 25% of the shares vesting on the first anniversary of the grant date and the remaining shares vesting in 36 equal monthly installments thereafter. Stock options granted as merit awards generally vest in 48 equal monthly installments following the grant date.
RSUsare share awards that entitle the holder to receive shares of common stock upon vesting and settlement of the awards. RSUs granted to employees generally vest over a four-year period with straight-line vesting in equal amounts, either in annual or quarterly installments. RSUs granted to newly hired non-executive employees generally vest over a four-year period, with 25% of the shares vesting on the first anniversary of the grant date and the remaining shares vesting in 12 equal quarterly installments thereafter. RSUs granted to newly hired executive employees generally vest over afour-year period, with shares vesting in four (4) equal annual installments. RSUs granted to executive and non-executive employees as merit awards generally vest in 16 equal quarterly installments following the grant date.
The Company initially reserved 5,200,000 shares of common stock for future issuance under the 2021 Plan. This initial reserve is subject to annual increase on the first day of each calendar year beginning on January 1, 2022 and ending on and including January 1, 2031. These annual increases are equal to thelesser of (i) 5% of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as determined by the Company's board of directors (the "Board"), subject to certain limitations. Pursuant to the evergreen provision, the initial share reserve was increased by 2,546,899 and 2,456,568 shares on January 1, 2025 and 2024, respectively.
At December 31, 2025 and 2024, there were 7,876,575 shares and 5,931,302 shares, respectively, of common stock available for issuance under the 2021 Plan.
The 2011 Plan was superseded by the 2021 Plan at the time of the initial public offering of the Company's common stock, which closed on July 15, 2021, and no further grants have been made under the 2011 Plan from the date the 2021 Plan became effective.
Stock Option Awards
The following table summarizes stock option activity under the 2011 and 2021 Plans:
| Number ofShares | Weighted-Average Exercise Price | Weighted-AverageContractual Term (in years) | Aggregate Intrinsic Value (in thousands) | |
|---|---|---|---|---|
| Outstanding, December 31, 2024 | 4,464,388 | $9.23 | 6.5 | $2,769 |
| Grants | — | — | ||
| Forfeited/cancelled | (763,751) | 8.85 | ||
| Exercised | (637,161) | 1.72 | ||
| Outstanding, December 31, 2025 | 3,063,476 | $10.88 | 5.5 | $3,315 |
| Vested and exercisable as of December 31, 2025 | 2,866,852 | $11.01 | 5.4 | $3,114 |
The Company did not grant any stock option awards during the year ended December 31, 2025. The weighted-average grant-date fair values of stock options granted during the year ended December 31, 2024 was $2.71 per share. The aggregate intrinsic value of stock options exercised, calculated as the difference between the exercise prices of the underlying stock options and the estimated fair value of the common stock on the date of exercise, was $2.9 million during the year ended December 31, 2025.
During the years ended December 31, 2025 and 2024, the Company recorded stock-based compensation expense of $4.1 million and $7.8 million, respectively, related to stock options. As of December 31, 2025, the unrecognized stock-based compensation of unvested stock options was $0.8 million, which is expected to be recognized over a weighted-average period of 0.9 years.
Determination of Fair Value
The grant date fair value of stock options granted was calculated via the Black-Scholes option-pricing model using the following weighted average assumptions:
| Years ended December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Expected term (in years) | N/A | 6.13 |
| Expected volatility | N/A | 61.67% |
| Risk-free interest rate | N/A | 4.28% |
| Dividend yield | N/A | – |
Restricted Stock Units
RSUs are share awards that entitle the holder to receive shares of common stock upon vesting and settlement. RSUs cannot be transferred, and the awards are subject to forfeiture if the holder’s employment terminates prior to the release of the vesting restrictions. RSUs granted generally vest over afour-year period with straight-line vesting in equal amounts
(eitherin annual or quarterly installments), provided the employee remains continuously employed with the Company. The fair value of an RSU is equal to the closing price of the Company’s common stock on the grant date.
The following table summarizes RSU activity under the 2021 Plan:
| Number ofShares | Weighted-Average Grant Date Fair Value Per Share | |
|---|---|---|
| Outstanding, December 31, 2024 | 4,341,818 | $5.6 |
| Grants | 3,159,258 | 3.1 |
| Forfeited/cancelled | (1,793,881) | 4.0 |
| Vested | (1,658,307) | 5.5 |
| Outstanding, December 31, 2025 | 4,048,888 | $4.4 |
During the years ended December 31, 2025 and 2024, the Company recorded stock-based compensation of $8.6 million and $8.7 million, respectively, related to RSUs. As of December 31, 2025, the unrecognized stock-based compensation associated with unvested RSUs was $13.7 million, which is expected to be recognized over a weighted-average period of 2.4 years.
Employee Stock Purchase Plan
In July 2021, the board of directors and stockholders approved the 2021 Employee Stock Purchase Plan (the “ESPP”). The ESPP permits participants to purchase shares of common stock at a discount through payroll deductions of up to a specified percentage of their eligible compensation. Shares of common stock are offered during two offering periods annually, each running for nine months, with the first offering period typically beginning in the second quarter, and the second offering period typically beginning in the fourth quarter. The purchase of shares for participants in the ESPP occurs at the conclusion of each offering period.
The Company initially reserved 850,000 shares of common stock for future issuance under the ESPP. This initial reserve is subject to annual increase on the first day of each calendar year beginning on January 1, 2022 and ending on and including January 1, 2031. These annual increases shall be equal to the lesser of (i) 1% of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as determined by the Board, subject to certain limitations. Pursuant to the evergreen provision, the initial share reserve was increased by 509,379 and 491,313 shares on January 1, 2025 and 2024, respectively.
As of December 31, 2025 and 2024, there were 1,880,211 shares and 1,631,076 shares of common stock available for issuance under the ESPP.
For the year ended December 31, 2025, participants in the ESPP purchased 260,244 shares for a total of $0.8 million. As of December 31, 2025, the Company has collected payroll withholdings of $0.1 million in the current offering period for the purchase of shares under the ESPP. For the years ended December 31, 2025 and 2024, the Company recorded stock-based compensation expense associated with the ESPP of $0.4 million and $0.6 million, respectively.
The fair value of shares to be issued under the ESPP was estimated using the Black-Scholes valuation model with the following assumptions for the years ended December 31, 2025 and 2024, respectively:
| Years ended December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Expected term (in years) | 0.49 - 0.50 | 0.49 - 0.50 |
| Expected volatility | 71.55% - 84.10% | 72.80% - 197.51% |
| Risk-free interest rate | 3.83% - 4.27% | 4.47% - 5.40% |
| Dividend yield | – | – |
The following is a summary of stock-based compensation expense by function (in thousands):
| Years Ended December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Cost of goods sold | $338 | $314 |
| Research and development | 1,980 | 2,157 |
| Selling, general and administrative | 10,736 | 14,606 |
| Total stock-based compensation expense | $13,054 | $17,077 |
Note 9. Net Loss per Share Attributable to Common Stockholders
Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. As the Company reported a net loss for the years ended December 31, 2025 and 2024, basic net loss per share is the same as diluted net loss per share as the inclusion of potentially dilutive shares would have been antidilutive if included in the calculation.
The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders (in thousands, except share and per share data):
| Years Ended December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Numerator: | ||
| Net loss attributable to common stockholders | $(38,426) | $(51,507) |
| Denominator: | ||
| Weighted-average shares of common stockoutstanding—basic and diluted | 52,148,543 | 50,134,104 |
| Net loss per share attributable to commonstockholders—basic and diluted | $(0.74) | $(1.03) |
The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share attributable to common stockholders for the period presented because including them would have been antidilutive:
| December 31, | ||
|---|---|---|
| 2025 | 2024 | |
| Options to purchase common stock | 3,063,476 | 4,464,388 |
| RSUs | 4,048,888 | 4,341,818 |

Internal Revenue Code (IRC) Section 382 limits the use of federal net operating losses and income tax credit carryforwards in certain situations where changes occur in stock ownership of a company. If the Company should have an ownership change of more than 50% of the value of the Company’s capital stock, utilization of the carryforwards could be restricted.
A valuation allowance is recorded when it is more likely than not that some portion of the deferred tax assets will not be realized. As of each reporting date, the Company's management considers all evidence, both positive and negative, that could impact management's view with regard to future realization of deferred tax assets. As of December 31, 2025, a full valuation allowance for deferred tax assets was recorded as management believes it is not more likely than not that all of the deferred tax assets will be realized. At December 31, 2025 and 2024, the Company has a net operating loss carryforward for federal income tax purposes of approximately $323.3 million and $269.2 million, respectively. At December 31, 2025 and 2024, the Company has a net operating loss carryforward for state income tax purposes of approximately $266.9 million and $245.0 million, respectively. Of the Company's federal net operating loss carryovers, $14.8 million was generated before January 1, 2018 and is subject to a 20-year carryforward period. The remaining $308.5 million can be carried forward indefinitely but is subject to an 80% taxable income limitation. The pre-2018 federal and certain state net operating losses will begin to expire in 2031 and 2032, respectively, if not utilized.
As of December 31, 2025 and 2024, the Company has federal research and development income tax credit carryforwards of approximately $2.8 million and $2.8 million, respectively. As of December 31, 2025 and 2024, the Company has state research and development income tax credit carryforwards of approximately $2.4 million and $2.3 million, respectively. The Federal income tax credits begin to expire in 2033. The California research and development credits can be carried forward indefinitely. The total amount of uncertain tax positions ("UTP") on research and development tax credits is $1.2 million and $1.3 million as of December 31, 2025 and 2024, respectively.
As of December 31, 2025 and 2024, the Company has business interest expense carryforwards of $0.8 million and $0.0 million, respectively. Business interest expense can be carried forward indefinitely.

Note 11. Segment Information
The Company’s Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), manages the business throughtwo operating segments, consistent with how the Company’s Chief Executive Officer: (i) assesses operating performance on a regular basis, (ii) makes resource allocation decisions, and (iii) designates responsibilities of his direct reports. The Company’s operating segments, which were renamed in 2025, and which also qualify as reportable segments include: (i) Interventional Glaucoma (formerly “Surgical Glaucoma”) and (ii) Interventional Dry Eye (formerly “Dry Eye”). The change in names of the operating segments has no impact on how the CODM manages the business. These segments are generally determined based on the decision-making structure and the grouping of similar products and services.
The Company’s CODM uses segment gross profit to assess the operating performance and make resource allocation decisions for each of its segments. Segment gross profit represents revenue reduced by cost of goods sold within each of the operating and reportable segments. The CODM reviews a monthly executive reporting package based on consolidated results of the Company when making decisions about allocating resources and assessing performance. The CODM evaluates actual segment performance to budget and forecast, including monthly sales performance, when allocating capital and personnel.
The Company does not have any intercompany transactions between segments that require elimination. The CODM does not review operating expenses separately for its segments, as the Company does not allocate operating expenses, with many operating costs shared between the segments, and therefore, this is not considered when allocating resources and assessing performance. The Company evaluated the monthly executive reporting package and did not identify any significant or other expenses for disclosure that are not already presented.
In reviewing and assessing segment performance and managing operations, management does not review segment assets. Substantially all of the Company’s revenue is generated from sales in the United States.
The following table summarizes select operating results information for each reportable segment (dollars in thousands):
| Years Ended December 31, | ||

Note 12. Subsequent Events
U.S. Tariff Update
On February 20, 2026, the United States Supreme Court issued a ruling striking down certain tariffs previously imposed under the International Emergency Economic Powers Act ("IEEPA"). The ultimate availability, timing, and amount of any potential refunds of such tariffs remain highly uncertain and are subject to further legal, regulatory, and administrative developments. Following the Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. There remains substantial uncertainty regarding the duration of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether additional tariffs or other retaliatory actions may be imposed, modified, or suspended, and the impacts of such actions on the Company's business. The Company continues to monitor and evaluate these developments and assess their potential impact on the Company’s business, financial condition, and results of operations.
