Glaukos Corp (NYSE:GKOS) Soars on Strong Q3 2025 Earnings Beat and Robust 2026 Outlook

Glaukos Corporation (NYSE:GKOS) reported financial results for the third quarter of 2025 that significantly exceeded analyst expectations, driving a substantial positive reaction in its stock price during after-hours trading.

Strong Revenue and Earnings Beat

The ophthalmic medical technology company posted record net sales of $133.5 million for the quarter ended September 30, 2025, representing a 38% increase compared to the same period last year. This performance comfortably surpassed analyst revenue estimates of approximately $125 million.

The company's bottom-line results also demonstrated marked improvement, with a non-GAAP net loss of $9.2 million, or ($0.16) per diluted share. This compares favorably to both the year-ago period's non-GAAP net loss of $15.2 million, or ($0.28) per diluted share, and analyst expectations for a loss of ($0.26) per share.

Key financial highlights from the quarter include:

• Record glaucoma net sales of $110.2 million, increasing 45% year-over-year
• U.S. glaucoma net sales of $80.8 million, surging 57% year-over-year
• Gross margin of approximately 78%, with non-GAAP gross margin of approximately 84%
• Operating loss improvement to $16.4 million from $24.7 million in Q3 2024

Market Reaction and Forward Guidance

The market responded positively to the earnings beat, with shares rising approximately 15.4% in after-hours trading following the announcement. This strong performance suggests investor confidence in the company's growth trajectory and execution of its strategic initiatives.

Management provided updated guidance that further bolstered optimism, raising its 2025 net sales outlook to a range of $490 million to $495 million, up from previous guidance of $480 million to $486 million. This updated forecast positions the company comfortably ahead of analyst sales estimates of approximately $494.3 million for the full year.

Perhaps most notably, Glaukos introduced preliminary 2026 net sales guidance of $600 million to $620 million, representing anticipated growth of approximately 22-26% over the midpoint of the raised 2025 guidance. This robust outlook significantly exceeds current analyst expectations and underscores management's confidence in the company's long-term growth prospects.

Business Momentum and Pipeline Development

Thomas Burns, Glaukos chairman and chief executive officer, attributed the strong results to "continued strong momentum in our business driven by successful global execution of our key strategic plans." The company highlighted its ongoing advancement of a "robust pipeline of novel, dropless platform technologies" designed to improve treatment outcomes for patients suffering from chronic eye diseases.

The company ended the quarter with a strong financial position, reporting approximately $277.5 million in cash, cash equivalents, short-term investments and restricted cash, with no outstanding debt.
