Statement Regarding Use of Non-GAAP Financial Measures
To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company uses certain non-GAAP historical financial measures. Management makes adjustments to the GAAP measures for items (both charges and gains) that (a) do not reflect the core operational activities of the Company, (b) are commonly adjusted within the Company's industry to enhance comparability of the Company's financial results with those of its peer group, or (c) are
inconsistent in amount or frequency between periods (albeit such items are monitored and controlled with equal diligence relative to core operations) (“Non-GAAP Purposes”). The Company uses the term "Non-GAAP" to exclude certain expenses, gains and losses to achieve the Non-GAAP Purposes, including external acquisition-related costs incurred to effect a business combination; amortization of intangible assets acquired in a business combination, asset purchase transaction or other contractual relationship; impairment of goodwill and intangible assets; certain in-process R&D charges; fair value adjustments to contingent consideration liabilities and pre-acquisition contingencies arising from a business combination; integration and transition costs related to business combinations; fair market value adjustments to inventories acquired in a business combination or asset purchase transaction; restructuring charges, duplicative operating expenses, or asset write-offs (or reversals) associated with exiting or significantly downsizing a business; unusual non-recurring expenses associated with inventory write-downs; gain or loss from the sale of a business; gain or loss on the mark-to-market adjustment, impairment, or sale of long-term investments; mark-to-market adjustments on derivative instruments that hedge income or expense exposures in a future period; significant legal litigation costs and/or settlement expenses or proceeds; legal and other associated expenses that are both unusual and significant related to governmental or internal inquiries; expenses, acceleration of amortization of debt issuance costs and gain or loss on debt extinguishment associated with the exchange or redemption of convertible senior notes; significant discrete income and other tax adjustments related to transactions as well as changes in estimated acquisition-date tax effects associated with business combinations, and the impact from implementation of tax law changes and settlements; and any other adjustment that is determined to be appropriate and consistent with the Non-GAAP Purposes. See “GAAP to Non-GAAP Reconciliations” for a reconciliation of each non-GAAP measure presented to the comparable GAAP financial measure.
In addition, in order to remove the impact of fluctuations in foreign currency exchange rates, the Company also presents certain net sales information on a constant currency basis, which represents the outcome that would have resulted had exchange rates in the current period been the same as the average exchange rates in effect in the comparable prior period. See “Reported Sales vs. Prior Periods” for a presentation of certain net sales information on a reported, GAAP and a constant currency basis.

Revenue Performance & Commercial Overview
Global Consolidated Revenue Performance
Glaukos reported record first quarter net revenues of $150.6 million that were up 41% on a reported basis, or 39% on a constant currency basis, versus 1Q 2025. Our first quarter record results reflect a sustained growth acceleration in our business with the strong performance driven by growing iDose® TR adoption and utilization, along with our broader Interventional Glaucoma, or IG, initiatives globally.
Franchise Revenue Performance
| APRIL 29, 2026 |
|---|
U.S. Glaucoma
Our record first quarter U.S. Glaucoma net revenues were approximately $93.5 million, representing year-over-year growth of 58% versus 1Q 2025 driven by growing contributions from iDose TR, which generated sales of approximately $54 million in the first quarter.
During the first quarter, we successfully advanced execution of our commercialization of iDose TR, a first-of-its-kind intracameral procedural pharmaceutical that was designed to continuously deliver glaucoma drug therapy for up to three years. Most importantly, clinical outcomes and product feedback from a growing number of cases and trained surgeons continue to be very positive and reaffirm our view that with the launch of iDose TR, we have the potential to deliver an interventional therapy to reshape glaucoma management for the benefit of patients with this sight threatening disease.
International Glaucoma
Our record first quarter International Glaucoma net revenues were approximately $35.8 million, representing year-over-year growth of 23% on a reported basis, or 16% on a constant currency basis, versus 1Q 2025. The strong growth internationally during the first quarter was broad-based as we continue to scale our international infrastructure and increasingly drive MIGS forward as the standard of care in each region and major market in the world.
We remain in the early stages of expanding our IG and product portfolio initiatives globally ahead of anticipated new product approvals and expanding market access in the years to come.
Corneal Health
Our first quarter Corneal Health net revenues were approximately $21.3 million, representing year-over-year growth of 15% versus 1Q 2025, including U.S. Photrexa® and very early Epioxa™ net sales of $17.7 million.
At the end of the first quarter, we were delighted to announce commercial availability of Epioxa, our novel, groundbreaking advancement in corneal cross-linking for the treatment of keratoconus, a rare, sight-threatening disease that is currently far too often undiagnosed and untreated. We believe Epioxa represents a transformative innovation in keratoconus care, offering an incision-free alternative to traditional corneal cross-linking procedures as it does not require the removal of the corneal epithelium, the outermost layer of the front of the eye. This novel, oxygen-enriched topical therapeutic, bioactivated by UV light, is designed to reduce the pain associated with removal of the epithelium, streamline the procedure, and minimize recovery, all while delivering clinically meaningful outcomes and exceptional value to patients, providers, and the healthcare system.
We will continue to focus on expanding access for keratoconus patients suffering from this rarely diagnosed disease.

Additional Commercial Updates & Commentary
We have had several additional positive commercial updates worth highlighting here:
- Advanced commercial launch activities in the U.S. for iDose TR
- Growing number of trained surgeons and accounts
- Increasing utilization by the installed active surgeon base
- Broadening and streamlining market access among MACs, commercial, and Medicare Advantage payers (Palmetto published professional fee for 0660T in late March 2026)
- Expanded set of peer-reviewed literature, now consisting of 22 different peer-reviewed publications highlighting iDose TR as a transformative new treatment alternative for patients suffering with glaucoma and ocular hypertension
- Accelerating marketing investments to support increased patient awareness and education
- Commenced initial commercial launch plans for Epioxa following October 2025 FDA approval
- Epioxa commercial availability announced March 19, 2026
- Successfully established, and continue to selectively expand, a broad-reaching site-of-care network, with acquired O2N systems already actively deployed at locations covering roughly 65% of the U.S. population, and a broader pipeline of systems moving through approval processes that would expand our treatment reach to approximately 95%
- Market access:
- Advancing efforts with payors to secure access pathways or policy coverage for Epioxa, with several plans having already updated or in the process of updating their policies to include the novel therapy
- Access pathways now established for more than 100 million covered commercial lives in the U.S., including with 4 of the 5 largest payors, reflecting encouraging initial receptivity of Epioxa’s clinical value
- CMS assigned a product-specific J-code for Epioxa, consistent with our expectations and in response to our application; this new code, J2789, is scheduled to take effect on July 1, 2026, and is expected to help streamline the reporting and reimbursement process for Epioxa among U.S. payors over time
- Deployed various new patient services and support programs
- Advancing targeted marketing and DTC campaigns designed to significantly enhance awareness, education, and detection, supported by greater optometric engagement and strengthened advocacy partnerships

2026 Revenue Guidance Raised to Reflect Strong Momentum
Glaukos now expects full-year 2026 global consolidated net sales of $620 - $635 million, up from its previous guidance of $600 - $620 million. This guidance attempts to take into consideration:
- Potential growing contributions from iDose TR as market access initiatives progress and broader IG initiatives take hold over the course of the year
- Potential growing contributions from Epioxa as commercial launch plans advance and permanent J-code is effective and solidified operationally
- Potential transient headwinds within our U.S. Corneal Health franchise associated with the Photrexa to Epioxa transition
- Potential growing contributions from iStent infinite as broader IG initiatives take hold
- Combo-cataract MIGS competition globally
- The continued estimated impact on U.S. Glaucoma volumes related to professional fee reimbursement for combination-cataract trabecular bypass surgery versus other more invasive alternatives
- The latest foreign currency exchange spot rates as of our 1Q 2026 earnings call on April 29, 2026
- Global macroeconomic and geopolitical environment and associated uncertainties, which at this time are difficult to predict

- Given the ongoing conversations around tariff and broader geopolitical volatility, we wanted to reiterate that we manufacture and source our products primarily within the U.S., and as such, expect minimal direct exposure to the most recently implemented tariff-related policies. That said, the global tariff environment remains fluid, and more broadly, the current geopolitical backdrop and macroeconomic uncertainties continue to evolve. As such, we will continue to closely monitor these situations given the overall instability in the marketplace and global macroeconomic uncertainties.

Statement Regarding Use of Non-GAAP Financial Measures
To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company uses certain non-GAAP historical financial measures. Management makes adjustments to the GAAP measures for items (both charges and gains) that (a) do not reflect the core operational activities of the Company, (b) are commonly adjusted within the Company's industry to enhance comparability of the Company's financial results with those of its peer group, or (c) are inconsistent in amount or frequency between periods (albeit such items are monitored and controlled with equal diligence relative to core operations) (“Non-GAAP Purposes”). The Company uses the term "Non-GAAP" to exclude certain expenses, gains and losses to achieve the Non-GAAP purposes, including external acquisition-related costs incurred to effect a business combination; amortization of intangible assets acquired in a business combination, asset purchase transaction or other contractual relationship; impairment of goodwill and intangible assets; certain in-process R&D charges; fair value adjustments to contingent consideration liabilities and pre-acquisition contingencies arising from a business combination; integration and transition costs related to business combinations; fair market value adjustments to inventories acquired in a business combination or asset purchase transaction; restructuring charges, duplicative operating expenses, or asset write-offs (or reversals) associated with exiting or significantly downsizing a business; unusual non-recurring expenses associated with inventory write-downs; gain or loss from the sale of a business; gain or loss on the mark-to-market adjustment, impairment, or sale of long-term investments; mark-to-market adjustments on derivative instruments that hedge income or expense exposures in a future period; significant legal litigation costs and/or settlement expenses or proceeds; legal and other associated expenses that are both unusual and significant related to governmental or internal inquiries; expenses, acceleration of amortization of debt issuance costs and gain or loss on debt extinguishment with the exchange or redemption of convertible senior notes; and significant discrete income and other tax adjustments related to transactions as well as changes in estimated acquisition-date tax effects associated with business combinations, and the impact from implementation of tax law changes and settlements; and any other adjustment that is determined to be appropriate and consistent with the Non-GAAP Purposes. See “Primary GAAP to Non-GAAP Reconciliations” for a reconciliation of each non-GAAP measure presented to the comparable GAAP financial measure. Beginning in the second quarter of 2022, we no longer exclude certain upfront and contingent milestone payments in connection with collaborative and licensing arrangements and certain in-process R&D charges for non-GAAP reporting and disclosure purposes.
In addition, in order to remove the impact of fluctuations in foreign currency exchange rates, the Company also presents certain net sales information on a constant currency basis, which represents the outcome that would have resulted had exchange rates in the current period been the same as the average exchange rates in effect in the comparable prior period. See “Additional GAAP to Non-GAAP Reconciliations” for a presentation of certain net sales information on a reported, GAAP and a constant currency basis.
