Second Quarter 2026 Financial Results

Total revenue in the second quarter of 2026 was $95.1 million, an increase of 3.0% from $92.3 million in the prior-year period, primarily driven by higher demand for portable oxygen concentrators, or POCs, in international markets and the favorable impact of foreign exchange rates. While U.S. sales and rentals remained below the prior-year period, the Company continued to gain traction with U.S. distributors and the expanded product portfolio, reinforcing confidence in its long-term opportunities in the U.S. market.

Total gross margin was 45.5% in the second quarter of 2026 compared to 44.8% in the prior-year period. Adjusted gross margin improved by 65 basis points to 45.6% compared to 44.9% in the prior-year period due to improvements in cost of revenue.

GAAP net loss for the second quarter of 2026 was $3.9 million compared to a net loss of $4.2 million in the prior-year period. Adjusted net loss improved $0.6 million year-over-year to less than $0.1 million in the second quarter of 2026, compared with an adjusted net loss of $0.7 million in the prior-year period.

Adjusted EBITDA was a positive $2.4 million in the second quarter of 2026, compared to a positive $2.1 million in the prior-year period, an improvement of $0.3 million.

Cash, cash equivalents, marketable securities, and restricted cash were $106.8 million as of June 30, 2026, with no debt outstanding. The Company repurchased 1,145,150 shares of its common stock in the first half of 2026 for consideration of $7.5 million under the share repurchase program that was announced in the first quarter of 2026.

Reconciliations of adjusted gross margin, adjusted EBITDA, and adjusted net loss for the three and six months ended June 30, 2026 and 2025 are in the financial schedules that are a part of this press release. An explanation of these non-GAAP financial measures is also included below under the heading "Reconciliation of U.S. GAAP to Non-GAAP Financial Measures."

Third Quarter and Full Year 2026 Financial Outlook

Inogen expects third quarter 2026 revenue to be approximately in line with third quarter 2025 revenue, reflecting the continued U.S. sales channel mix shift as well as the timing impact of select international distributor inventory purchases.

For the full year 2026, Inogen now expects reported revenue in the range of $355 million to $361 million, reflecting approximately 3% growth at the midpoint of the range relative to the Company’s 2025 revenue.

The Company now expects full year 2026 adjusted EBITDA of approximately $4.0 million representing a 48.1% increase from $2.7 million reported in 2025.

The Company has not provided a reconciliation of forward-looking Adjusted EBITDA to the most directly comparable GAAP measure because certain items that impact net income are uncertain or outside the Company's control and cannot be reasonably predicted without unreasonable effort.

Non-GAAP Financial Measures

Inogen has presented certain financial information in accordance with U.S. GAAP and also on a non-GAAP basis for the three and six months ended June 30, 2026, and June 30, 2025. Management believes that these non-GAAP financial measures, taken in conjunction with U.S. GAAP financial measures, provide useful information for both management and investors by excluding certain non-cash and other expenses that are not indicative of Inogen’s core operating results. Management uses these non-GAAP measures to compare Inogen’s performance relative to forecasts and strategic plans, to benchmark Inogen’s performance externally against competitors, and for certain compensation decisions. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Inogen's operating results as reported under U.S. GAAP. Inogen encourages investors to carefully consider its results under U.S. GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. Reconciliations between U.S. GAAP and non-GAAP results are presented in the accompanying tables of this release.
