Glaukos (GKOS) Q2 2026 earnings review

Transformational Product Launches Drive 50% Sales Acceleration

Glaukos delivered a massive quarter, with Q2 revenue surging 50% YoY to a record $185.6M, crushing previous estimates. The growth was spearheaded by the explosive adoption of iDose TR ($74M) and the much-anticipated launch of Epioxa ($11M). While the company remains unprofitable with a GAAP net loss of $18.4M, the aggressive top-line expansion and favorable product mix pushed Non-GAAP gross margins to 85%. Management capitalized on this momentum by aggressively raising FY26 sales guidance from $620-635M to $680-700M.

๐Ÿ‚ Bull Case

iDose TR is a Blockbuster in the Making

Generating $74M in Q2, iDose TR adoption is accelerating rapidly. It is successfully shifting the treatment paradigm toward interventional glaucoma, validating management's long-term 'forever patient' strategy.

Epioxa Defies Transition Fears

Management previously warned of a 'material dip' in Q2 Corneal Health revenue due to a Photrexa transition lag. Instead, the segment surged 48% YoY, generating $30.4M, indicating intense early demand for the incision-free Epioxa.

๐Ÿป Bear Case

Profitability Goal Requires Flawless Execution

Despite 50% revenue growth, SG&A and R&D expenses jumped nearly 40%. The company is spending heavily to fuel these launches, meaning absolute cash flow breakeven remains a future target rather than a current reality.

International Competition is Mounting

International Glaucoma growth decelerated relative to the U.S. segment. Management explicitly cited global combo-cataract MIGS competition as a headwind factored into their guidance.

โš–๏ธ Verdict: ๐ŸŸข

Bullish. The sheer velocity of the iDose TR and Epioxa revenue ramps is undeniably impressive. While operating expenses remain high, the massive top-line beat, expanding gross margins, and dramatically raised guidance point to a highly successful commercial execution phase.

Key Themes

DRIVER NEW ๐ŸŸข๐ŸŸข

iDose TR Adoption is Accelerating

iDose TR sales jumped to ~$74M in Q2, up from $54M in 26Q1 and $31M a year ago. This sequential and year-over-year acceleration proves that surgeons are eagerly adopting this interventional glaucoma therapy. With CMS proposed rules potentially compressing physician fees for combination cataract-MIGS procedures, standalone Category III treatments like iDose TR are becoming increasingly attractive to comprehensive ophthalmologists.

DRIVER NEW ๐ŸŸข

Epioxa Launch Reverses 'Dip' Narrative

In previous quarters, management guided for a 'material dip' in Q2 2026 Corneal Health sales due to patient warehousing during the transition from Photrexa to Epioxa. Reversing expectations, the Corneal Health segment surged 48% YoY to $30.4M, with Epioxa contributing ~$11M early in its launch. With Epioxa's permanent J-code (J2789) going live on July 1, reimbursement friction should evaporate, paving the way for explosive second-half growth.

DRIVER ๐ŸŸข

Product Mix Drives Margin Expansion

Stable and impressive margin accretion continues. Non-GAAP gross margin reached 85% in Q2, up 200 bps from 83% in 25Q2. This expansion is a direct mathematical result of the sales mix shifting heavily toward high-margin proprietary platforms like iDose TR and Epioxa.

CONCERN ๐Ÿ”ด

Surging Operating Expenses Contradict Leverage Narrative

While management previously touted a 'clean line of sight' to cash-flow breakeven, expenses are accelerating. GAAP SG&A rose 39% YoY to $116.1M, and R&D jumped 40% YoY to $51.3M. While justifiable given the dual commercial launches, this significant step-up in spend ensures operating losses will persist in the near term despite 50% top-line growth.

CONCERN ๐Ÿ”ด

International Glaucoma Decelerating Amid Competition

International Glaucoma posted $36.6M in sales. While this represents a respectable 17% YoY reported growth, it is a stable to decelerating metric compared to the explosive 64% growth seen in U.S. Glaucoma. Management explicitly highlighted 'combo-cataract MIGS competition globally' and competitive product trialing as ongoing headwinds.

CONCERN โšช

Macroeconomic and Tariff Risks Lingering

Management continues to flag the 'global macroeconomic and geopolitical environment and associated uncertainties' as a factor in their guidance. While they noted minimal direct exposure to recent tariff policies because their manufacturing and sourcing are primarily U.S.-based, they remain cautious about secondary global supply chain effects.

Other KPIs

Total U.S. Glaucoma Sales $118.5 million

Accelerating dramatically. Growth hit 64% YoY, an intense step up from the ~58% YoY growth seen in 26Q1 and 45% YoY in 25Q2. This segment now accounts for 64% of the company's total revenue, cementing the U.S. Interventional Glaucoma transition as Glaukos's absolute core driver.

Cash and Short-Term Investments $289.3 million

Stable. Up slightly from $280.5M sequentially. The company continues to carry zero traditional debt. This healthy cash cushion allows Glaukos to fully fund the aggressive SG&A marketing pushes for Epioxa and iDose TR without immediate dilution risk.

Guidance

FY26 Net Sales Guidance $680 - $700 million

Accelerating significantly. Management raised the midpoint by $62.5M (from $627.5M to $690M). At the $690M midpoint, this implies a massive 36% YoY growth rate compared to FY25's $507.4M. This upgrade clearly telegraphs management's confidence that the Q2 beat was not a one-off pull-forward, but structural momentum.

Key Questions

Epioxa J-Code Impact

With Epioxa generating roughly $11M under a slower miscellaneous J-code in Q2, how much warehoused demand is expected to unlock immediately in Q3 now that the permanent J2789 code is active?

Pacing the Path to Profitability

R&D and SG&A expenses grew ~40% YoY this quarter. As the heavy lifting for the Epioxa launch subsides, at what specific revenue run-rate do you expect to see meaningful absolute dollar reductions in non-GAAP operating losses?

International Strategy Pivot

You noted global combo-cataract MIGS competition as a headwind. Are there plans to alter pricing or commercial strategies internationally to defend market share, or is the focus purely on accelerating iStent infinite adoption in the EU?
