Insulet Corp. (NASDAQ:PODD), the maker of the Omnipod tubeless insulin pump system, closed its fiscal 2025 with a strong fourth quarter, delivering revenue that met lofty expectations and adjusted earnings that surpassed them. The company's forward guidance, however, presents a more nuanced picture, which appears to be reflected in the stock's mixed initial reaction.
Quarterly Performance vs. Expectations
The company's headline numbers for the fourth quarter ended December 31, 2025, demonstrated robust demand for its flagship Omnipod products.
- Revenue: Came in at $783.8 million, representing a 31.2% year-over-year increase. This figure was essentially in line with analyst estimates, which had anticipated approximately $784.1 million.
- Adjusted Earnings Per Share (EPS): Was a clear beat at $1.55, comfortably exceeding the consensus estimate of $1.48. This represents a 34.8% increase from the $1.15 per share reported in Q4 2024.
The performance was driven by exceptional international growth, with Omnipod revenue outside the U.S. soaring 50.7% (41.7% on a constant currency basis). U.S. Omnipod revenue also grew a healthy 28.0%. For the full year 2025, total revenue reached $2.71 billion, up 30.7%.
Market Reaction and Forward Guidance
Following the earnings release, the stock experienced notable volatility. In pre-market trading, shares rose over 5%, likely an immediate positive reaction to the EPS beat and strong revenue growth. However, this early enthusiasm appears to have been tempered as investors digested the company's outlook for 2026.
Management provided the following constant currency revenue growth guidance:
- Q1 2026: Total revenue growth of 25% - 27%.
- Full Year 2026: Total revenue growth of 20% - 22%.
When compared to existing analyst estimates, this guidance presents a mixed signal:
- The midpoint of the Q1 2026 guidance range implies revenue of approximately $716.9 million, which is slightly below the current analyst consensus of $727.6 million.
- Conversely, the midpoint of the full-year 2026 guidance suggests revenue of about $3.25 billion, which is modestly above the analyst sales estimate of $3.31 billion.
This juxtaposition—a near-term forecast that may fall short of expectations against a full-year outlook that meets or exceeds them—helps explain the stock's choppy price action, which saw gains pared back from the pre-market peak.
Key Highlights from the Report
Beyond the financial figures, Insulet's press release underscored several strengths in its business foundation:
- Market Leadership: The company stated it ranked #1 in new customer starts in both the U.S. and Europe in 2025 and was the most requested and prescribed Automated Insulin Delivery (AID) system in the U.S.
- User Base Expansion: It achieved a milestone of over 600,000 estimated active Omnipod users globally.
- Capital Return: The Board approved a $350 million increase to its share repurchase authorization, with plans to execute approximately $300 million of buybacks in Q1 2026, signaling confidence in its financial strength and commitment to shareholder returns.
- Profitability Growth: For 2026, the company expects adjusted operating margin to expand by approximately 100 basis points and adjusted EPS growth to exceed 25%.
Conclusion
Insulet's fourth-quarter results cap off a year of exceptional growth, proving its Omnipod platform continues to gain significant market share in the diabetes care sector. The earnings beat is a positive testament to its operational execution and pricing power. However, the market's measured reaction highlights investor focus on the future. The company's guidance for 2026, while still projecting strong double-digit growth, introduces a note of caution for the immediate next quarter relative to expectations, even as the full-year view remains solid.
