SPECIA L NOTE REGARDING FORWARD-LOOKING STATEMENTS

Unless the context otherwise requires, references in this Quarterly Report on Form 10-Q to the “Company,” “Sight Sciences,” “we,” “us” and “our” refer to Sight Sciences, Inc.

This Quarterly Report on Form 10-Q for the fiscal period ended June 30, 2025 (this "Quarterly Report") contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding our future results of operations or financial condition, business strategy and plans, and objectives of management for future operations, are forward-looking statements. In some cases, you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “hope,” “intend,” “may,” “might,” “objective,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” or “would” or the negative of these words or other similar terms or expressions. These forward-looking statements include, but are not limited to, statements concerning the following:

•
our ability to obtain and maintain sufficient reimbursement for our products, including our ability to successfully protect reimbursement for our Surgical Glaucoma products and establish sufficient reimbursement for our Dry Eye products;
•
our ability to manage and grow our business by maintaining and expanding our sales to existing customers or introducing our products to new customers;
•
estimates of our total addressable market, future revenue, expenses, margins, capital requirements, and our needs for additional financing;
•
our ability to compete effectively with existing competitors and new market entrants;
•
our ability to maintain compliance with, and retain favorable payment terms under our current secured credit facility;
•
our ability to scale our infrastructure to achieve our business objectives;
•
geopolitical tensions, including with respect to trade policies, government regulations and tariffs, and the related impacts on the cost of our products and gross margins;
•
our evaluation and expansion of additional third-party manufacturing locations, and the related costs and impacts on our business;
•
our ability to establish and maintain intellectual property protection for our products or avoid claims of infringement, as well as potential impacts to our business that may result from intellectual property related litigation;
•
potential effects of extensive government regulation;
•
our ability to protect and scale our intellectual property portfolio;
•
our ability to hire and retain key personnel;
•
our ability to obtain financing in future offerings;
•
the volatility of the trading price of our common stock;
•
our expectation regarding the time during which we will be an emerging growth company under the Jumpstart Our Business Startups Act (the "JOBS Act") or a smaller reporting company under applicable Securities and Exchange Commission ("SEC") rules; and
•
our ability to maintain proper and effective internal controls.

Actual events or results may differ from those expressed in or implied by forward-looking statements. As such, you should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Quarterly Report primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, operating results, prospects, strategy,

3

and financial needs. The outcomes of the events described in these forward-looking statements are subject to risks, uncertainties, assumptions, and other factors described in the section titled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 8, 2025 (our "Annual Report"), and elsewhere in this Quarterly Report. Moreover, we operate in a highly competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements in this Quarterly Report are based upon information available to us as of the date of this Quarterly Report. While we believe that such information provides a reasonable basis for these statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

You should read this Quarterly Report and the documents that we reference in this Quarterly Report and have filed as exhibits to this Quarterly Report with the understanding that our actual future results, performance and achievements may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. The forward-looking statements made in this Quarterly Report relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report to reflect events or circumstances after the date of this Quarterly Report or to reflect new information, actual results, revised expectations, or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements.

Notes to Condensed C onsolidated Financial Statements (Unaudited)

Note 1. 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: Surgical Glaucoma and Dry Eye. The products for the Surgical 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 and the OMNI EDGE Surgical System are implant-free, minimally invasive glaucoma surgery (MIGS) technology. OMNI is indicated in the United States to reduce intraocular pressure in adult patients with primary open-angle glaucoma. The Ergo Series of the OMNI Surgical System 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 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 (“MGD”) 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 June 30, 2025, the Company had an accumulated deficit of $372.4 million and recorded a net loss of $26.1 million for the six months 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 condensed consolidated financial statements and accompanying notes thereto are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") applicable to interim periods and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X. The Company’s condensed 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.

The unaudited condensed consolidated financial statements have been prepared on a basis consistent with the audited consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair

10

presentation of the Company's financial information contained herein. The condensed consolidated balance sheet as of December 31, 2024 is derived from the Company's consolidated audited financial statements as of that date. These interim condensed consolidated financial statements do not include all disclosures required by US GAAP and should be read in conjunction with the Company's audited consolidated financial statements and the accompanying notes thereto for the fiscal year ended December 31, 2024, which are contained in the Annual Report. The Company's results of operations for the six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any other interim period.

Use of Estimates

The preparation of the unaudited condensed consolidated 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.

New Accounting Pronouncements

Accounting Standards Recently 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 for fiscal year reporting. The standard is to be applied on a prospective basis although optional retrospective application is permitted. While the standard will require additional disclosures related to the Company’s income taxes within the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, the standard did not have any impact on the Company’s consolidated operating results, financial condition or cash flows.

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 to the consolidated financial statements about certain expenses such as purchases of inventory, employee compensation, depreciation, intangible asset amortization, and other expenses which are presented on 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.

As of June 30, 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:

11

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 Company's cash and cash equivalents included Level 1 investments in U.S. treasury securities and money market funds. The Company had investments in money market funds of $21.3 million and $6.4 million as of June 30, 2025 and December 31, 2024, respectively. In addition, the Company had investments in U.S. treasury securities of $75.8 and $106.5 million as of June 30, 2025 and December 31, 2024, respectively. These U.S. treasury securities are classified as held-to-maturity and all have been purchased with original maturities of 90 days or less. Held-to-maturity debt securities are recorded at amortized cost in the financial statements.

|  | June 30, 2025 |
|  | Amortized Cost |  |  | Unrealized Gains |  |  | Unrealized Losses |  |  | Aggregate Fair Value |
U.S. treasury securities |  | $ | 75,776 |  |  | $ | 5 |  |  | $ | (2 | ) |  | $ | 75,779 |

|  | December 31, 2024 |
|  | Amortized Cost |  |  | Unrealized Gains |  |  | Unrealized Losses |  |  | Aggregate Fair Value |
U.S. treasury securities |  | $ | 106,535 |  |  | $ | 37 |  |  | $ | — |  |  | $ | 106,572 |

The Company measures the fair value of outstanding debt for disclosure purposes on a recurring basis. As of June 30, 2025 and December 31, 2024, total debt of $39.8 million and $39.4 million was 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. These warrants are classified as Level 3 liabilities. As of June 30, 2025 and December 31, 2024, respectively the fair value of these warrants was less than $0.1 million. These warrants are remeasured at each reporting date following execution of the Hercules Loan Agreement. See Note 5, Debt, and Note 7, Stockholders' Equity, for additional information regarding the common stock warrants.

The financial statements as of June 30, 2025 and December 31, 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)

13

Loan, the “Term Loans"). Tranche 2 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 is not available to the Company. Tranche 3 consists 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 provides 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 is not available to the Company. 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 June 30, 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 June 30, 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 has various operating leases, which include facility leases and equipment leases. Operating leases are recorded on the consolidated balance sheets as both a right-of-use asset ("ROU asset") and lease liability, which are recognized based on the present value of the future minimum lease payments over the lease term. In determining the present value of these lease payments, the Company uses its incremental borrowing rate ("IBR") based on the information available at the lease commencement date if the rate implicit in the lease is not readily determinable. The Company’s 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. In determining the lease term, the Company includes all renewal options that are reasonably probable to be executed.

The Company leases its corporate headquarters in Menlo Park, California. The lease commenced in August 2021 and was originally for a term of 37 months from the commencement date. In December 2023, the Company entered into an amendment to the lease, extending the lease term an additional 26 months. Upon signing the amendment, the Company recorded an aggregate lease ROU asset and lease liability of $1.2 million. The lease ROU asset and corresponding lease liability were estimated using a weighted-average IBR of 11.40%. Total base rent for the amended 34 months under the amended lease agreement is approximately $1.5 million.

The Company recognizes rent expense on a straight-line basis over the noncancelable lease term. The Company’s rent expense was $0.1 million and $0.2 million for the three months ended June 30, 2025 and 2024, respectively. The Company’s rent expense was $0.3 million and $0.4 million for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025, the weighted average remaining lease term for the leases was 1.3 years.

Operating lease expense and supplemental cash flow information related to operating leases for the three and six months ended June 30, 2025 and 2024 were as follows (in thousands):

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 judgement 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 not yet decided whether to proceed with 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 are instituted and 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 judgements 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

16

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 June 30, 2025 and December 31, 2024, 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 June 30, 2025 and December 31, 2024.

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 June 30, 2025, no dividends have been declared. Each share of common stock is entitled to one vote.

At June 30, 2025 and December 31, 2024, the Company had reserved common stock for future issuances as follows:

|  | June 30, |  |  | December 31, |
|  | 2025 |  |  | 2024 |
Common stock available for future grants |  |  | 6,261,778 |  |  |  | 5,931,302 |
Common stock options issued and outstanding |  |  | 4,135,802 |  |  |  | 4,464,388 |
Restricted stock units outstanding |  |  | 5,935,081 |  |  |  | 4,341,818 |
Shares available for future purchase under employee stock purchase plan |  |  | 1,996,797 |  |  |  | 1,631,076 |
Common stock reserved for issuance upon exercise of outstanding warrants |  |  | 161,783 |  |  |  | — |
Total |  |  | 18,491,241 |  |  |  | 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. The warrants are classified as equity. During the year ended December 31, 2024, the fair value of the issued warrants

17

recorded was $0.7 million, which was calculated using the Black-Scholes option-pricing model. These warrants were recorded at fair value upon their issuance in additional paid-in capital in the consolidated balance sheets. These warrants are not remeasured after their respective issuance dates.

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 liabilities in other noncurrent liabilities in the consolidated financial statements. The fair value of the unissued warrants was initially recorded upon the funding of the Hercules Loan Agreement. As of June 30, 2025 and December 31, 2024, respectively, the fair value of the unissued warrants recorded was less than $0.1 million calculated using the Black-Scholes option-pricing model. The unissued warrants are remeasured at each reporting date after the funding of the Initial Loan.

Note 8. Equity Incentive Plans

2011 Stock Option Plan and 2021 Incentive Award 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 of the stock option may be granted for periods of up to five years. The ISOs and NSOs will be 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.

RSUs are 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 a four-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 the lesser 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 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.

As of June 30, 2025 and December 31, 2024, there were 6,261,778 shares and 5,931,302 shares, respectively, of common stock available for issuance under the 2021 Plan.

18

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 2021 Plan during the periods presented:

|  | Number of Shares |  |  | Weighted-Average Exercise Price |  |  | Weighted-Average Contractual Term (in years) |  |  | Average Intrinsic Value (in thousands) |
Balances as of December 31, 2024 |  |  | 4,464,388 |  |  | $ | 9.23 |  |  |  | 6.5 |  |  | $ | 2,769 |

During the three months ended June 30, 2025 and 2024, the Company recorded stock-based compensation expense of $1.2 million and $1.9 million related to stock option awards, respectively. During the six months ended June 30, 2025 and 2024, the Company recorded stock-based compensation expense of $2.8 million and $3.8 million related to stock option awards, respectively. The Company did not grant any stock options during the six months ended June 30, 2025. The weighted-average grant-date fair values of stock options granted during the six months ended June 30, 2024 was $2.71.

The aggregate intrinsic value of stock options exercised during the three and six months ended June 30, 2025 was $0.1 million and $0.1 million, respectively. The aggregate intrinsic value was 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. As of June 30, 2025, the unrecognized stock-based compensation expense relating to unvested stock opti ons was $2.6 million, which is expected to be recognized over a weighted-average period of approximately 1.1 years.

Determination of Fair Value

The Company estimated the grant date fair value of stock options using the Black-Scholes option-pricing model, which requires the use of highly subjective and complex valuation assumptions to determine the fair value of stock-based awards, including the option’s expected term, the expected volatility of the underlying stock, the risk-free interest rate, and the expected dividend yield. For purposes of the Black-Scholes valuation model, the Company used the simplified method for determining the expected term of the granted stock options since the Company does not have adequate historical data to utilize in calculating the expected term. The grant date fair value of stock options granted was calculated using the following weighted average assumptions:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2025 |  | 2024 |  | 2025 |  | 2024
Expected term (in years) |  | N/A |  | 6.13 |  | N/A |  | 6.13
Expected volatility |  | N/A |  | 61.67% |  | N/A |  | 61.67%
Risk-free interest rate |  | N/A |  | 4.28% |  | N/A |  | 4.28%
Dividend yield |  | N/A |  | – |  | N/A |  | –

During the three months ended June 30, 2025 and 2024, the Company recorded stock-based compensation expense of $2.5 million and $2.3 million related to the RSUs, respectively. During the six months ended June 30, 2025 and 2024, the Company recorded stock-based compensation expense of $5.0 million and $4.6 million related to the RSUs, respectively. As of June 30, 2025, the unrecognized stock-based compensation expense relating to RSUs was $21.0 million, which is expected to be recognized over a weighted-average period of approximately 2.6 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 six 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 June 30, 2025 and December 31, 2024, there were 1,996,797 and 1,631,076 shares of common stock available for issuance under the ESPP, respectively.

During the three and six months ended, June 30, 2025, participants purchased 143,658 shares for $0.4 million under the ESPP. As of June 30, 2025, the Company has collected payroll withholdings of $0.1 million in the current offering period for the purchase of shares under the ESPP. The Company recorded stock-based compensation expense of $0.1 million related to the ESPP for the three months ended June 30, 2025 and 2024. The Company recorded stock-based compensation expense of $0.2 million related to the ESPP for the six months ended June 30, 2025 and 2024.

The grant date fair value of shares issuable under the ESPP was calculated using the Black-Scholes valuation model using the following assumptions:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2025 |  | 2024 |  | 2025 |  | 2024
Expected term (in years) |  | 0.49 – 0.50 |  | 0.49 – 0.50 |  | 0.49 – 0.50 |  | 0.49 – 0.50

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 three and six months ended June 30, 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 for the periods presented (in thousands, except share and per share data):

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net loss attributable to common stockholders |  | $ | (11,941 | ) |  | $ | (12,329 | ) |  | $ | (26,095 | ) |  | $ | (28,595 | )
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Weighted-average shares of common stock outstanding—basic and diluted |  |  | 51,821,773 |  |  |  | 49,903,386 |  |  |  | 51,557,686 |  |  |  | 49,694,825 |
Net loss per share attributable to common stockholders—basic and diluted |  | $ | (0.23 | ) |  | $ | (0.25 | ) |  | $ | (0.51 | ) |  | $ | (0.58 | )

The following potentially dilutive issued and outstanding 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 as a result of the net loss position:

|  | June 30, |
|  | 2025 |  |  | 2024 |
Stock option awards |  |  | 4,135,802 |  |  |  | 4,675,830 |

Total |  |  | 10,232,666 |  |  |  | 9,597,040 |

Note 10. Segment Information

The Company’s Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), manages the business through two operating segments, consistent with how the CODM: (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 also qualify as reportable segments include: (i) Surgical Glaucoma and (ii) Dry Eye. These segments are generally determined based on the decision-making structure and the grouping of similar products and services.

The 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

21

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 (in thousands):

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |

Note 11. Subsequent Events

On July 4, 2025, H.R.1 - One Big Beautiful Bill Act ("OBBBA") was enacted into law. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the impact on its consolidated financial statements.

Ite m 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes and other financial information included in Part I, Item 1, “Financial Statements,” within this Quarterly Report and our audited consolidated financial statements and related notes included in Part II, Item 8, “Financial Statements and Supplementary Data,” in our Annual Report. Certain statements included in this discussion and analysis constitute “forward-looking statements” that are subject to considerable risks and uncertainties. Please see the information under the heading “Special Note Regarding Forward-Looking Statements” in this Quarterly Report.

Overview

Sight Sciences’ mission is to develop transformative, interventional technologies that allow eyecare providers to procedurally elevate the standards of care – empowering people to keep seeing. We are passionate about improving patients’ lives by helping them preserve their sight. Our objective is to develop and market products for use in new treatment paradigms and to create an interventional mindset in eyecare whereby our products may be used in procedures which supplant conventional outdated approaches. Our business philosophy is grounded in the following principles:

•
comprehensively understanding disease physiology;
•
developing transformative technologies that are intended to preserve, protect and restore natural physiological functionality to diseased eyes;
•
developing and marketing products with proven clinical evidence that achieve superior effectiveness versus current treatment paradigms while minimizing complications or side effects;
•
providing intuitive, patient-friendly, interventional solutions to ophthalmologists and optometrists (together, "ECPs"); and
•
delivering compelling economic value to all stakeholders, including patients, providers and third-party payors such as Medicare and commercial insurers.

O ur initial product development has focused on the treatment of two of the world’s most prevalent and underserved eye diseases, glaucoma and dry eye disease (“DED”). We have commercialized products in each of our two reportable operating segments, Surgical Glaucoma and Dry Eye. Our Surgical Glaucoma revenue consists of sales of our OMNI® Surgical System family of products ("OMNI"), currently comprised of our Ergo Series OMNI Surgical System and OMNI Edge Surgical System, and the SION® Surgical Instrument ("SION"), while our Dry Eye revenue consists of sales of the TearCare® System ("TearCare"), and related components and accessories. Each product is primarily sold through a highly involved direct sales model that offers intensive education, training and customer service. We believe this model not only enables us to differentiate our products and company from competitors, but also expands our addressable market by educating ECPs, patients and other stakeholders on our products and evolving treatment paradigms. Outside of the U.S., we have established direct commercial operations in the United Kingdom and Germany. We also sell OMNI in several other countries in Europe through distributors.

We sell OMNI and SION to facilities where ophthalmic surgeons perform outpatient procedures, such as ambulatory surgery centers ("ASCs") and hospital outpatient departments ("HOPDs"), which are typically reimbursed by Medicare or private payors for procedures using our products. We are focused on educating surgeons on the clinical benefits of earlier interventions with the comprehensive OMNI procedure, engagement efforts with accounts in light of reimbursement clarity, enhanced competitive counter selling, investments in targeted commercial resources, pseudophakic standalone market development, and the recent launch of our OMNI Edge Surgical System, an expansion of the OMNI family.

We sell TearCare to ECPs. Currently, there is no meaningful reimbursement coverage by Medicare or private payors for DED procedures, including TearCare, and patients typically pay out-of-pocket for TearCare, although some payors may agree to provide case-based coverage outside of a formal policy. We are continuing our controlled commercial launch and are focused on our comprehensive, clinical data-driven, long-term market development plan that aims to improve awareness and patient access to TearCare. In the fourth quarter of 2024, we instituted a price increase for our TearCare products to reflect the clinical value of our technology as part of our strategy to establish broader coverage with commercial payors and Medicare. This increase materially reduced customer demand for

23

TearCare in the fourth quarter of 2024 and the first half of 2025, and we believe it will continue to impact demand in the future unless and until broader reimbursement coverage can be established.

We have dedicated meaningful resources to execute our commercial strategy, while also seeking to reduce operating expenses and improve cost efficiencies to better align our operating structure for long-term, profitable growth. The overall success of our approach to eyecare to date is evidenced by over 330,000 estimated uses of Surgical Glaucoma products and their predicates in over 2,200 hospitals and ASCs in the U.S. and Europe, and over 70,000 estimated uses of TearCare in over 1,500 eyecare facilities in the U.S. through June 30, 2025.

We do not have, and do not currently intend to develop, any internal manufacturing capabilities or infrastructure, and rely on a limited number of third-party manufacturers, many of which are single source suppliers, for the components, accessories and materials that are utilized in the assembly of our products. We believe the manufacturing capacity provided by our current suppliers will be adequate to meet our current and anticipated manufacturing needs across all of our product lines. However, as part of our long-term manufacturing strategy, we are actively expanding third party manufacturing capacity and options for our products which we expect to be available to us starting in the first quarter of 2026 for certain products. We plan to continue to utilize third party contract manufacturers for our products and any related components.

Revenue in our Surgical Glaucoma segment for the six-months ended June 30, 2025 and 2024 was $36.3 million and $38.5 million, respectively, with gross margins for the same periods of 86.1% and 88.0%, respectively. Revenue in our Dry Eye segment for the six-months ended June 30, 2025 and 2024 was $0.7 million and $2.1 million, respectively, with gross margins for the same periods of 55.8% and 44.4%, respectively. For the six-months ended June 30, 2025, we generated more than 90% of our revenue from customers in the U.S.

Our Surgical Glaucoma revenue was down for the six months ended June 30, 2025 compared to the same period in 2024 due to a number of factors, including reimbursement coverage changes and increased competition from other MIGS devices. We expect to continue to experience adverse revenue impacts arising out of the restrictions on the performance of multiple MIGS procedures in combination with cataract surgery for Medicare patients in the jurisdictions administered by the five Medicare Administrative Contractors (“MACS”) that issued the local coverage determinations (“LCDs”) containing such restrictions, which restrictions became effective in the fourth quarter of 2024. We believe that these restrictions have led to a decrease in the number of overall MIGS devices used in procedures that are being performed, including procedures utilizing our OMNI technology. In addition, we expect our Surgical Glaucoma gross margins will be adversely impacted in 2025 by the tariffs imposed by the U.S. on China, since most of our OMNI and SION products are currently produced and assembled by a Taiwan-based manufacturer in China. In the six months ended June 30, 2025, we incurred increased cost of goods sold associated with tariff-related expenses of $0.1 million.

Our Dry Eye revenue was down for the six months ended June 30, 2025 compared to the same period in 2024 due to lower demand in the Dry Eye segment resulting from our increase in TearCare component pricing which took effect on October 1, 2024, as part of our strategy to achieve reimbursed market access for the TearCare procedure, though there is no guarantee as to the timing of reimbursement decisions or the amount of reimbursement. Given the earlier stage of TearCare’s commercial development, we expect our Dry Eye segment’s gross margins to be lower than our Surgical Glaucoma segment’s gross margins for the near- and medium-term due to the allocation of fixed labor and overhead costs to the segment's cost of goods sold. In addition, our Dry Eye gross margins could be adversely impacted in future periods by the tariffs imposed by the U.S. on China, since most of our TearCare SmartLids, are produced and assembled by a Taiwan-based manufacturer in China. However, there was no tariff impact for the six months ended June 30, 2025 due to our usage of inventory purchased prior to the implementation of these tariffs.

We expect Dry Eye gross margin to improve over time as market access expands, although these improvements may be partially offset by the impact of tariffs.

We believe in the importance of continued strategic investment in initiatives that:

•
further demonstrate our products’ clinical effectiveness and safety to potential customers, patients, payors and regulators, including (i) establishing OMNI and SION as standards of care of interventional glaucoma treatment among MIGS-trained surgeons, (ii) developing a standalone market segment with a focus on pseudophakic patients whose IOP is not well-controlled on two or more medications and who are at risk of disease progression, and (iii) increasing customer advocacy and pursuing equitable reimbursement including establishing coverage and/or payment rates for TearCare;

24

•
enhance our commercial capabilities and expertise, including resources dedicated to sales, marketing and education;
•
ensure the broadest possible patient access to the treatment alternatives that our products are cleared to offer;
•
enhance and improve upon our existing product technologies;
•
develop our existing international markets and expand into new international markets; and
•
allow us to create transformational and interventional technology innovation with new products, devices or drugs, in glaucoma and ocular surface disease or in new eye disease areas.

As a result, we intend to continue to invest in product development, market access, sales and marketing, clinical studies, and education initiatives. Because of these and other factors, we expect to continue to incur net losses for at least the next several years, and we may seek additional debt and equity financing to fund our operations and planned growth.

To date, our primary sources of capital have been private placements of redeemable convertible preferred stock, debt financing agreements, the sale of common stock in our initial public offering (“IPO”), and revenue from the sale of our products. As of June 30, 2025, we had cash and cash equivalents of $101.5 million, an accumulated deficit of $372.4 million and an outstanding interest-bearing term loan balance of $40.0 million plus a $2.4 million final payment under the Hercules Loan Agreement (excluding debt discount and amortized debt issuance costs).

Factors Affecting Our Business and Results of Operations

We believe there are several important factors that have impacted and that will continue to impact our business, financial condition, and results of operations. Except as described in Part II, Item 1A, "Risk Factors," of this Quarterly Report, there have been no material changes to such factors from those described in our Annual Report under the heading "Factors Affecting Our Business and Results of Operations."

Components of Our Results of Operations

Revenue

We currently derive the majority of our U.S. revenue from the sale of our OMNI and SION products to ASCs and HOPDs and from the sale of our TearCare products to ECPs. To date, the revenue from our Surgical Glaucoma segment has accounted for over 90% of our total revenue, substantially all of which was generated from sales within the U.S. Our Surgical Glaucoma customers place orders based on their expected procedure volume and reorder as needed, typically on a biweekly, monthly or bimonthly basis. Our TearCare customers typically purchase a TearCare System which consists of one or more TearCare SmartHubs® (“SmartHubs”), multiple single-use TearCare SmartLids® (“SmartLids”) and other accessories. After utilizing their initial inventory, customers can reorder SmartLids as needed. No single customer accounted for 10% or more of our revenue for the six months ended June 30, 2025 and 2024.

The growth of our revenue is primarily driven by the demand for elective surgery and treatment utilizing our products in the United States and Europe, product reimbursement rates and coverage criteria, and competition. Such demand is often lower during summer months because of ECP vacations and in winter months because of fewer business or surgery days due to holidays and adverse weather conditions.

Cost of Goods Sold

Our components and products are produced by third-party suppliers and manufacturers. Our cost of goods sold consists primarily of amounts paid for our products to third-party manufacturers, and our manufacturing overhead costs, which consist primarily of personnel expenses, including salaries, benefits and stock-based compensation, and reserves for excess, obsolete and non-sellable inventory. Cost of goods sold also includes depreciation expenses for production equipment which we provide to our third-party manufacturers and certain direct costs, such as shipping and handling costs and tariffs on imported products and components.

Gross Profit and Gross Margin

We calculate gross profit as revenue minus cost of goods sold. We calculate gross margin as gross profit divided by revenue. Our gross profit and gross margin have been, and we believe they will continue to be, affected

25

by a variety of factors, including differences in segment gross profit and gross margins, changes in average selling prices, changes in product reimbursement rates, product sales mix, production and ordering volumes, manufacturing, tariff and freight costs, product yields, and headcount. In general, we expect our gross profit to increase over time as our revenue increases, and we expect our gross margins to increase over the long term to the extent our production and ordering volumes increase and as we spread the fixed portion of our overhead costs over a larger number of units produced.

We intend to use our design, engineering and manufacturing know-how and capabilities to further advance and improve the efficiency of our suppliers’ manufacturing processes, which we believe will reduce costs and increase our gross margins. However, we expect our gross margins will be adversely impacted by the tariffs imposed by the U.S. on China and other manufacturing countries of origin for our products for as long as the tariffs are in effect. Most of our OMNI and SION products, as well as our TearCare SmartLids, are currently produced and assembled by a Taiwanese manufacturer out of its China manufacturing facilities; however we expect that a portion of our product volumes will be produced in additional manufacturing facilities outside of China starting with our OMNI Edge product line in the first quarter of 2026, with additional products added in 2026.

Our gross margins could fluctuate from quarter to quarter due to a number of factors, including variations in product mix, changes in product reimbursement rates or average selling prices, transitions to new suppliers, introduction of new products by us or our competitors, adoption of new manufacturing processes and technologies, and responses to evolving macroeconomic and geopolitical conditions, including the adoption of new or increased tariffs by the United States, China, and other countries.

Research and Development Expenses

Research and development ("R&D") expenses consist primarily of costs associated with engineering, product development, clinical studies to develop and support our products, including clinical trial design, clinical trial site initiation and study costs, internal and external costs associated with our regulatory compliance and quality assurance functions, medical affairs, cost of products used for clinical trials and other costs associated with products and technologies that are in development. These expenses also include personnel expenses, including salaries, benefits and stock-based compensation, supplies, consulting, prototyping, testing, materials, travel expenses, depreciation expenses for equipment and an allocation of information technology ("IT") and facility overhead expenses.

Our R&D expenses as a percentage of revenue may vary over time depending on the level and timing of new product development efforts, as well as clinical development, clinical trial and other related activities. We expect our R&D expenses to increase for the next several years as we continue to invest in our active clinical trial programs, develop new products, and improve our existing products.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses consist primarily of personnel expenses, including salaries, benefits and stock-based compensation related to selling, marketing and corporate functions, allocation of IT and facility overhead expenses, bad debt expense, finance, legal and human resource costs. Other SG&A expenses include training, travel expenses, promotional activities, marketing initiatives, market research and analysis, conferences and trade shows, professional services fees (including external legal, audit, consulting and tax fees), insurance costs, and general corporate expenses.

Our SG&A expenses as a percentage of revenue may vary over time depending on the level and timing of commercial expansion efforts. We expect our SG&A expenses to increase for the next several years as we continue to invest in our commercial team and market access initiatives and launch new products.

Investment Income

I nvestment income primarily consists of interest and amortization on held-to-maturity investments in U.S. treasury securities and money market funds.

Interest Expense

Interest expense consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to the accretion of debt discount and amortization of debt issuance costs associated with the Term Loans.

Loss on Debt Extinguishment

26

The loss on debt extinguishment is associated with the termination and settlement of the Prior Loan Agreement.

Other Income (Expense), Net

Other income (expense), net primarily consists of income and expenses that do not originate from our primary business.

Revenue. Revenue was $19.6 million during the three months ended June 30, 2025, a decrease of $1.8 million, or 8.5% compared to $21.4 million in the prior year comparable period. Our Surgical Glaucoma revenue for the three months ended June 30, 2025 was $19.2 million, a decrease of $1.0 million, or 5.0%, from the prior year comparable period. The overall decrease in Surgical Glaucoma revenue was primarily attributable to a decrease in the number of OMNI units sold in the comparable periods. This decrease was primarily driven by a decrease in unit utilization per ordering facility, primarily due to the restrictions on the performance of multiple MIGS procedures in combination with cataract surgery for Medicare patients in the jurisdictions administered by the five MACS that issued the LCDs containing such restrictions, which restrictions became effective in the fourth quarter of 2024.

27

Our Dry Eye revenue for the three months ended June 30, 2025 was $0.3 million, a decrease of $0.8 million, or 70.4%, from the prior year comparable period. The overall decrease in Dry Eye revenue was primarily due to decreased volumes of SmartLids purchased, and fewer new customers added in the period, which led to lower SmartHub revenue. The primary reason that fewer products were sold was due to our focus on the next phase of our commercial strategy for the Dry Eye segment, which involves achieving reimbursed market access for our TearCare products instead of generating sales through a cash-pay model.

Cost of Goods Sold. Cost of goods sold was $3.0 million during the three months ended June 30, 2025, flat compared to $3.0 million in the prior year comparable period. Our Surgical Glaucoma cost of goods sold increased $0.3 million as compared to the prior year comparable period. The increase was primarily driven by higher overhead costs per unit, tariff costs, and product sales mix, partially offset by higher average selling prices. Our Dry Eye cost of goods sold decreased $0.4 million in the three months ended June 30, 2025 compared to the prior year comparable period, primarily driven by lower revenue.

Gross Profit and Gross Margin. Our total gross profit was $16.6 million in the three months ended June 30, 2025, a decrease of $1.8 million from the prior year comparable period. Our gross margin for the three months ended June 30, 2025 decreased to 84.8%, from 85.8% in the prior year comparable period. Gross margin in our Surgical Glaucoma segment was 85.6% for the three months ended June 30, 2025, a decrease from 88.0% for the prior year comparable period, primarily due to higher overhead costs per unit, tariff costs, and product sales mix. In our Dry Eye segment, gross margin decreased from 46.5% for the three months ended June 30, 2024 to 38.4% for the three months ended June 30, 2025, primarily driven by product sales mix and higher overhead costs per unit associated with lower sales volumes.

Research and Development Expenses. R&D expenses were $4.4 million for the three months ended June 30, 2025, an increase of less than $0.1 million from the prior year comparable period. R&D expenses were consistent in the comparative periods with slightly lower general R&D expenses and payroll expenses, partially offset by increased spending in other areas in the prior period.

Selling, General, and Administrative Expenses. SG&A expenses were $23.9 million for the three months ended June 30, 2025, a decrease of $2.8 million from the prior year comparable period. The decrease was primarily driven by a $2.3 million decrease in legal expenses, a $0.6 million decrease in stock-based compensation expenses, and a $0.3 million decrease in commissions and bonuses. Partially offsetting these expense decreases was a $0.4 million increase in payroll-related expenses.

Investment Income. Investment income was $1.0 million for the three months ended June 30, 2025, a decrease of $0.5 million from the prior year comparable period, due to lower investment balances as well as lower yields on held-to-maturity investments during the current period.

Interest Expense. Interest expense increased $0.1 million during the three months ended June 30, 2025 compared to the prior year comparable period, due to higher outstanding principal balances on the Hercules Loan Agreement.

Loss on Debt Extinguishment. There was no loss on debt extinguishment for either of the three months ended June 30, 2025 and 2024.

Other Income (Expense), Net. Other income (expense), net was income of less than $0.1 million for the three months ended June 30, 2025, compared to expense of less than $0.1 million for the prior year comparable period.

Revenue. Revenue was $37.1 million during the six months ended June 30, 2025, a decrease of $3.6 million, or 8.8% compared to $40.6 million in the prior year comparable period. Our Surgical Glaucoma revenue for the six months ended June 30, 2025 was $36.3 million, a decrease of $2.2 million, or 5.6%, from the prior year comparable period. The overall decrease in Surgical Glaucoma revenue was primarily attributable to a decrease in the number of OMNI units sold in the current period compared to the prior year comparable period. This decrease was primarily driven by a decrease in unit utilization per ordering facility, primarily due to the restrictions on the performance of multiple MIGS procedures in combination with cataract surgery for Medicare patients in the jurisdictions administered by the five MACS that issued the LCDs containing such restrictions, which restrictions became effective in the fourth quarter of 2024.

Our Dry Eye revenue for the six months ended June 30, 2025 was $0.7 million, a decrease of $1.4 million, or 65.9%, from the prior year comparable period. The overall decrease in Dry Eye revenue was primarily due to decreased volumes of SmartLids purchased after our TearCare System price increases that went into effect on October 1, 2024 and fewer new customers added in the period, which led to lower SmartHub revenue. The primary reason that fewer products were sold was due to our focus on the next phase of our commercial strategy for the Dry Eye segment, which involves achieving reimbursed market access for our TearCare products instead of adding customers through a cash-pay model.

29

Cost of Goods Sold. Cost of goods sold was $5.4 million during the six months ended June 30, 2025, a decrease of $0.4 million from $5.8 million in the prior year comparable period. Our Surgical Glaucoma cost of goods sold increased $0.4 million as compared to the prior year comparable period. The increase was primarily driven by higher overhead costs per unit, tariff costs, and product sales mix.

Our Dry Eye cost of goods sold decreased $0.9 million in the six months ended June 30, 2025 compared to the prior year comparable period, primarily driven by lower revenue resulting from the shift in pricing strategy, partially offset by higher average selling prices.

Gross Profit and Gross Margin. Our total gross profit was $31.7 million in the six months ended June 30, 2025, a decrease of $3.1 million from the prior year comparable period. Our gross margin for the six months ended June 30, 2025 decreased to 85.5%, from 85.7% in the prior year comparable period. Gross margin in our Surgical Glaucoma segment was 86.1% for the six months ended June 30, 2025, a decrease from 88.0% for the prior year comparable period, primarily due to product sales mix and higher overhead costs per unit. In our Dry Eye segment, gross margin increased from 44.4% for the six months ended June 30, 2024 to 55.8% for the six months ended June 30, 2025, primarily driven by the price increase for our TearCare SmartLids.

Research and Development Expenses. R&D expenses were $8.8 million for the six months ended June 30, 2025, a decrease of $0.1 million from the prior year comparable period. R&D expenses were consistent period over period, with a slight decline in payroll expenses and general R&D expense from the prior year comparable period, which were partially offset by increased spending in other areas.

Selling, General, and Administrative Expenses. SG&A expenses were $48.4 million for the six months ended June 30, 2025, a decrease of $4.8 million from the prior year comparable period. The decrease was primarily driven by a $5.3 million decrease in legal expenses, a $1.0 million decrease in stock-based compensation expenses, and a $0.7 million decrease in commissions and bonuses. These declines were partially offset by a $1.1 million increase in sales training and marketing costs, and a $1.0 million increase in payroll-related expenses.

Investment Income. Investment income was $2.2 million for the six months ended June 30, 2025, a decrease of $1.0 million from the prior year comparable period, due to lower investment balances as well as lower yields on held-to-maturity investments during the current period.

Interest Expense. Interest expense increased $0.2 million during the six months ended June 30, 2025 compared to the prior year comparable period, due to higher outstanding principal balances associated with the Hercules Loan Agreement.

Loss on Debt Extinguishment. There was no loss on debt extinguishment for the six months ended June 30, 2025. We recognized loss on debt extinguishment of $2.0 million for the six months ended June 30, 2024, associated with refinancing the indebtedness under our prior secured credit facility (the “Prior Loan Agreement”).

Other Income (Expense), Net. Other expense, net was expense of $0.1 million for the six months ended June 30, 2025, compared to expense of less than $0.1 million for the prior year comparable period.

Net Cash Used in Operating Activities. Net cash used in operating activities for the six months ended June 30, 2025 was $19.1 million, consisting primarily of a net loss of $26.1 million, as well as a net change in our operating assets and liabilities of $2.2 million, partially offset by non-cash charges of $9.1 million. The net change in our operating assets and liabilities was primarily due to a $4.5 million decrease in accrued compensation. This change was partially offset by a $1.1 million decrease in accounts receivable, a $0.4 million increase in accounts payable,

30

and a $0.1 million decrease in our inventory balance. The non-cash charges primarily consisted of $8.1 million related to stock-based compensation expense, $0.5 million of accretion of debt discount and debt issuance costs, $0.3 million of depreciation and amortization, and $0.2 million of noncash operating lease expense.

Net cash used in operating activities for the six months ended June 30, 2024 was $19.3 million, consisting primarily of a net loss of $28.6 million, as well as a net change in our operating assets and liabilities of $1.4 million, partially offset by non-cash charges of $10.7 million. The net change in our operating assets and liabilities was primarily due to a $5.7 million increase in accounts receivable and a $1.3 million decrease in other noncurrent liabilities. Accrued and other current liabilities increased $1.9 million, while both inventory and prepaid expenses and other current assets increased by $1.2 million. In addition, accrued compensation increased by $0.9 million and accounts payable increased by $0.6 million. The non-cash charges primarily consisted of $8.8 million related to stock-based compensation expense, $1.0 million of noncash loss on the extinguishment of debt, $0.4 million of depreciation and amortization and $0.3 million of noncash operating lease expense.

Net Cash (Used in) Provided by Financing Activities. Net cash provided by financing activities for the six months ended June 30, 2025 was $0.5 million, consisting primarily of proceeds from the exercise of stock options and proceeds from employee stock plan purchases. Net cash used in financing activities for the six months ended June 30, 2024 was $0.5 million, consisting primarily of the costs associated with the refinancing of the outstanding term loan agreement.

Liquidity and Capital Resources

Sources of Liquidity

To date, our primary sources of capital have been private placements of redeemable convertible preferred stock, the sale of common stock in our IPO, debt financing arrangements, and revenue from the sale of our products. In January 2024, we 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 senior secured term loan facility in the aggregate principal amount of up to $65.0 million. We used the proceeds from an initial $35.0 million tranche (the “Initial Loan”) funded under the Hercules Loan Agreement to discharge our indebtedness under the Prior Loan Agreement with our prior lenders. In December 2024, we consummated the drawdown of the $5.0 million Tranche I(b) term loan advance (the "Tranche I(b) Loan") contemplated by the Hercules Loan Agreement.

As of June 30, 2025, we had cash and cash equivalents of $101.5 million, an accumulated deficit of $372.4 million, and an outstanding term loan balance of $40.0 million plus a $2.4 million final payment under the Hercules Loan Agreement (excluding debt discount and amortized debt issuance costs). Based on our current planned operations, we expect our cash and cash equivalents balance, as well as other sources of liquidity, will enable us to fund our operations for at least the next 12 months and the foreseeable future.

Our historical cash outflows have primarily been associated with cash used for operating activities such as sales, marketing and commercialization of our products, research and development activities, regulatory and market access activities, intellectual property enforcement and portfolio expansion, capital expenditures and debt service costs. Our cash requirements will be significantly impacted by our ability to manage and grow our business by maintaining and expanding our sales to existing customers or introducing our products to new customers; our ability to obtain and maintain sufficient reimbursement for our products, including successfully protecting reimbursement for our Surgical Glaucoma products and establishing sufficient reimbursement for our Dry Eye products; the level of our investment in commercialization and research and development activities, including clinical trials; whether we enter into any strategic acquisitions or investments, and the timing and amount of the associated capital expenditures; our entry and expansion into new markets; the outcome of our litigation against Alcon, including receipt of any final, non-appealable award thereunder; and competitive dynamics within our industry. There are numerous factors that may impact our long-term cash requirements, and we are unable to accurately predict them at this time. An extended period of global supply chain disruption, geopolitical or trade tensions, or economic uncertainty could materially affect our business, results of operations, financial condition, and access to sources of liquidity. For example, the U.S. has recently imposed tariffs that apply to all of our products and product

31

components imported from China, which will increase the cost of our products and components and have a negative impact on our gross margins and liquidity.

We may in the future need to seek additional sources of liquidity and capital resources through equity or debt financings, such as additional securities offerings or through borrowings under a new or existing credit facility. There can be no assurance that such transactions will be available to us on favorable terms, if at all.

Hercules Capital Loan Agreement

In January 2024, we entered into the Hercules Loan Agreement with the Lenders, which provides for a maximum $65.0 million credit facility. An Initial Loan of $35.0 million was funded under the Hercules Loan Agreement on January 22, 2024, which was used to discharge our indebtedness under the Prior Loan Agreement. On December 10, 2024, we consummated the drawdown of the $5.0 million 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 us (the “Tranche Loans,” and together with the Initial Loan and the Tranche I(b) Loan, the “Term Loans). Tranche 2 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 milestones were not met and thus this Tranche 2 is not available to the Company. Tranche 3 consists 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 provides for a maturity date of July 1, 2028, with an interest only period running for the first 30 months of the agreement term. This interest-only period was 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 milestones were not met by the June 30, 2025 deadline and thus the six-month extension of the interest only period is not available to the Company. 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 June 30, 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, we issued warrants to the Lenders to purchase up to an aggregate of 135,686 shares of our 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, we issued additional warrants to the Lenders to purchase 26,095 shares of our 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, we 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 we draw 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 us and our future subsidiaries, subject to exceptions for certain foreign subsidiaries. The obligations under the agreement are secured by substantially all of our assets, including its material intellectual property. Additionally, we are subject to customary affirmative and negative covenants, including covenants that limit or restrict our ability 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. We are also subject to certain minimum cash and revenue covenants under the Hercules Loan Agreement. We were in compliance with all covenants as of June 30, 2025.

While any Term Loans remain outstanding under the Hercules Loan Agreement, we are required to use commercially reasonable efforts to grant to the Lenders the option to invest up to $3.0 million in our 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.

Leases

Our corporate headquarters are located in Menlo Park, California, where we lease approximately 11,000 square feet of office, research and development, engineering and laboratory space pursuant to a lease that commenced on August 1, 2021 and expires on October 31, 2026.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Estimates

Our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities, and the reported amounts of revenue and expense during the reporting period. We evaluate our estimates and assumptions on an ongoing basis using historical experience, existing and known circumstances, authoritative accounting guidance, and various other factors we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material.

There have been no material changes to our critical accounting estimates as compared to the critical accounting estimates described in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report under the heading “Critical Accounting Estimates."

JOBS Act Accounting Election

The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to use this extended transition period under the JOBS Act. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make comparison of our financial statements to those of other public companies more difficult.

Recently Issued Accounting Pronouncements

See Note 2, Summary of Significant Accounting Policies, in the notes to our unaudited condensed consolidated financial statements in this Quarterly Report for recent accounting pronouncements not yet adopted as of the date hereof.

Ite m 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate risk. Our exposure to interest rate risk is principally confined to our cash and cash equivalents and the Hercules Loan Agreement.

As of June 30, 2025, we had cash and cash equivalents of $101.5 million, which consisted of bank deposits, money market funds, and U.S. treasury bills. We believe that we do not have any material exposure to changes in the fair value of these assets as a result of changes in interest rates due to the short-term nature of our cash and cash equivalents.

The Hercules Loan Agreement contains a floating rate equal to the greater of 10.35% or the Prime Rate plus 2.35%, with an interest rate equal to 10.35% as of June 30, 2025. Based upon the balance outstanding as of June 30, 2025, a hypothetical 1.0% (100 basis points) change in interest rates would not have a material impact on our financial statements.

There have been no material changes to such risks from those described in our Annual Report under the heading "Quantitative and Qualitative Disclosures About Market Risk."

Ite m 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

33

Our management, with the participation and supervision of our principal executive officer and our principal financial and accounting officer, evaluated our disclosure controls and procedures. The term 'disclosure controls and procedures,' as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to a company's management, including its principal executive officer, and principal financial and accounting officer, as appropriate to allow timely decisions regarding required disclosure.

Based on this evaluation, our principal executive officer and principal financial and accounting officer concluded that as of June 30, 2025, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHE R INFORMATION

Ite m 1. Legal Proceedings.

Except as set forth in Note 6, Commitments and Contingencies, in the notes to the unaudited condensed consolidated financial statements in this Quarterly Report, we do not believe we are currently a party to any legal proceedings, regulatory matters, or other disputes or claims which, if determined adversely to us, would, individually or taken together, have a material adverse effect on our business, financial condition, operating results, liquidity or future prospects. However, we may, in the ordinary course of business, face various claims brought by third parties, and we may, from time to time, make claims or take legal actions to assert our rights, including intellectual property rights, as well as claims relating to employment matters and the safety or effectiveness of our products. Any of these claims could subject us to costly litigation, and, while we generally believe that we have adequate insurance to cover many different types of liabilities, our insurance carriers may deny coverage, may be inadequately capitalized to pay on valid claims, or our policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on our business, financial condition, results of operations and liquidity. Additionally, any such claims, whether or not successful, could damage our reputation and business, and may have an adverse impact on us as a result of defense and settlement costs, diversion of management time and resources, and other factors.

Ite m 1A. Risk Factors.

Except as set forth below, we are not aware of any material changes to the risks and uncertainties described under the heading "Risk Factors" in our Annual Report, which are incorporated herein by reference. The risks described in our Annual Report are not the only ones we face. Additional risks we currently do not know about or that we currently believe to be immaterial may also impair our business, financial condition, operating results, liquidity, and future prospects.

We rely on third parties to manufacture and supply all of our products, and a substantial portion of our products and components are manufactured in China. A number of our suppliers are also single-source providers. We are subject to numerous risks relating to our reliance on such third-party suppliers, including the impact of tariffs on products imported from China.

Our business strategy depends on our ability to manufacture our current and future products in sufficient quantities, on terms acceptable to us, and on a timely basis to meet customer demand, while adhering to product quality standards, complying with regulatory requirements, and managing manufacturing and import costs. We do not have, and do not currently intend to develop, any internal manufacturing capabilities or infrastructure, and we rely on a limited number of third-party manufacturers, many of which are single-source suppliers, for the components, accessories, materials and assembly that we utilize in our products. Specifically, most of our OMNI and SION products, as well as our TearCare SmartLids, are produced and assembled by a single Taiwan-based

34

manufacturer in China. These commercial products comprise substantially all of our current revenue. Our suppliers may be unwilling or unable to supply products or components to us reliably and at the levels we anticipate or that are required by our customers, or we may be unable to purchase these items on terms that are acceptable to us, or at all.

Our suppliers must be able to provide us with products and components in compliance with regulatory requirements, including the FDA’s Quality System Regulation (“QSR”) and other applicable laws or regulations, in accordance with agreed-upon specifications, at acceptable costs and on a timely basis. If our suppliers are unable or unwilling to meet our demand requirements, we may not have enough of our products available for delivery to support ECPs that utilize our products as part of their treatment. For instance, if the supply of our products and components from our manufacturer in China was interrupted or suspended for any significant period, we may be unable to meet customer demand for these products during that time. Our ability to obtain products and components in sufficient quantities and on a timely basis from our suppliers may be limited for several reasons, including quality issues at their manufacturing facilities, damage to their manufacturing equipment or facilities, problems with their own suppliers, inability to obtain components required for our products, their financial difficulties, our relative importance as a customer to each supplier, or prohibitive cost increases associated with importing items from certain regions where our suppliers are located. Any shortfall in the supply of our products may result in lower adoption and utilization rates of our products by ECPs, as well as harm to our reputation, either of which could have a material adverse effect on our business, financial condition and results of operations.

Geopolitical tensions between the U.S. and China, and between the U.S. and other countries, have created considerable political and economic unrest and uncertainty that may adversely impact our business. As discussed above, most of our products are produced and assembled at a manufacturing facility in China. There is currently significant uncertainty about the relationship between the U.S. and China with respect to a number of geopolitical issues, including trade policies, government regulations and tariffs, and we expect this uncertainty will continue in future periods. Commencing in February 2025, the U.S. has imposed a significant new tariff on products imported from China. The tariff rate has fluctuated significantly since its inception and may continue to vary materially in the future.

This tariff applies to all of our products and product components imported from China. China has responded with certain retaliatory tariffs, and the U.S. and China could implement additional retaliatory tariffs. The China tariff has increased the cost of our products and components and will likely have a negative impact on our gross margins for as long as it remains in effect. For instance, at the previously implemented tariff rate of 145%, we expected that our Surgical Glaucoma segment’s unmitigated tariff exposure would increase its cost of goods sold by between approximately $3.5 million and $4.5 million for full year 2025. Although this 145% tariff rate was subsequently lowered, there can be no assurance that U.S. tariff rate on products imported from China will not increase again or materially and adversely affect our cost of goods sold in the future. Any further escalation in the use of retaliatory trade tariffs between the U.S. and China could cause a further increase in the cost of our products and components. There is also the risk that new tariffs could be implemented with other U.S. trading partners. These tariffs may cause supply chain disruptions and will also likely increase the shipping and other logistical costs involved in importing our products and components, which would further adversely impact our gross margins.

To mitigate these risks, we are evaluating additional manufacturing locations to produce and assemble our products and are in the process of establishing additional manufacturing lines outside of China. We have also increased our inventory levels of certain products to reduce the impact of further China tariff increases. However, at least through 2025 and into 2026, we expect the substantial majority of our products will continue to be manufactured in China, and will therefore continue to be subject to the prevailing tariff rates.

The process of identifying and qualifying additional manufacturing facilities could be time-consuming and expensive, result in interruptions in our operations, cause delays in the supply of our products, or affect the quality or performance specifications of our products. We cannot assure you that we will be able to identify and engage additional contract manufacturers on terms similar to our current arrangements or that are otherwise favorable to us. In addition, we cannot guarantee that the cost associated with obtaining products and components from an additional manufacturer, including any associated tariffs, will be lower than the costs associated with obtaining products from our current manufacturers, or that any reduction in the costs will be sufficient to offset the cost of adding new manufacturers. Furthermore, any change in our manufacturers could require us to complete another qualification process at the manufacturer’s facility, and there is no guarantee the facility would pass our quality audit. The occurrence of any of these events could increase our operating costs or harm our ability to meet the demand for our

35

products in a timely manner, either of which could have a material adverse effect on our business, financial condition and results of operations.

We do not typically enter into long-term supply agreements with our third-party manufacturers and do not anticipate doing so in the near term. Accordingly, we will continue to be subject to the risk that our suppliers can cancel our agreements on relatively short notice, or that we will be unable to renew or extend contracts and arrangements with such third parties on terms that are favorable to us, or at all. These risks are likely to be exacerbated by our limited experience manufacturing our current products and negotiating agreement terms with third party manufacturers.

If demand for our products increases, we will have to invest additional resources to manage the manufacturing process. If we fail to secure increased production capacity efficiently, we may not be able to respond to customer demand on a timely basis, our sales may not increase in line with our expectations, and our operating margins could fluctuate or decline. In addition, the manufacture of future products may require modification of our current production processes, the identification of new suppliers for specific components, sub-assemblies and materials, or the development of new manufacturing processes or technologies. It may not be possible for our current third-party manufacturers to produce these products at a cost or in quantities sufficient to make these products commercially viable or to maintain current operating margins, all of which could have a material adverse effect on our business, financial condition and results of operations.

We have been party to, and may in the future become a party to intellectual property litigation or administrative proceedings that could be costly, time-consuming, unsuccessful, and could interfere with our ability to sell and market our products.

Competitors may infringe our patents, or we may be required to enforce our patents to protect our technology. We may also be required to file suit to protect our trade secrets or may be involved in litigation defending against claims of infringement of the rights of others. In addition, our patents also may become involved in inventorship, priority or validity disputes. To counter or defend against such claims can be expensive and time-consuming and could divert our attention from other functions and responsibilities. In an infringement proceeding, a court may decide that a patent owned by us is invalid or unenforceable. Furthermore, even if our patents are found to be valid and infringed, a court may refuse to grant injunctive relief against the infringer and instead grant us monetary damages and/or ongoing royalties. Such monetary compensation may be insufficient to adequately offset the damage to our business caused by the infringer’s competition in the market. Adverse determinations against us in defending against infringement could subject us to significant liabilities to third parties, require us to seek licenses from third parties and prevent us from manufacturing, selling or using the product, any of which could severely harm our business. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our management and other personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on our common stock price. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Any of the foregoing could have a material adverse effect on our business, financial condition or results of operations.

On September 16, 2021, we 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 our 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. Our complaint sought money damages and injunctive relief. On January 24, 2022, Ivantis asserted counterclaims requesting declaratory judgments that our asserted patents-in-suit are not infringed and/or invalid. On August 1, 2022, we filed an amended complaint alleging that Alcon Inc., Alcon Vision, LLC and Alcon Research,

36

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 our asserted patents-in-suit are not infringed and/or are invalid. In September 2022, Ivantis and Alcon filed petitions with the U.S. Patent Office 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 U.S. Patent Office (“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, we were 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 held an in-person hearing to hear the parties’ oral arguments on their post-trial briefings at the conclusion of which, the Court ordered the parties to engage in non-binding mediation. In early March 2025, we and Alcon informed the Court that we had not resolved our dispute through mediation and asked the Court to decide the parties’ post-trial motions and enter a judgement, which judgement will be subject to appeal. It is possible that the jury verdict that was rendered in our favor may be reduced, limited or vacated by the Court or by the appellate court if appealed.

In June 2025, Alcon filed petitions with the USPTO for ex parte reexaminations, challenging the validity of each of the three patents that we asserted in the litigation based on prior art patents and publications. The USPTO has not yet decided whether to proceed with the reexaminations. We intend to defend our patents vigorously in front of the USPTO. However, it is possible that the April 2024 jury verdict in our favor, including our ability to collect past damages and ongoing royalties, may be materially and adversely impacted if the reexamination proceedings are instituted and 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 judgements of invalidity by the USPTO could include vacating the jury verdict and finding the patents invalid. We are 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 on us.
