Inogen Announces Second Quarter 2025 Financial Results

Delivered strong top-line results; raising full year 2025 revenue expectations

GOLETA, Calif., August 7, 2025 -- Inogen, Inc. (Nasdaq: INGN), a medical technology company offering innovative respiratory products for use in the homecare setting, today announced financial results for the quarter ended June 30, 2025.

Recent Highlights

•

Achieved second quarter 2025 revenue of $92.3 million, a year-over-year increase of 4.0%, marking the sixth consecutive quarter of mid-single-digit percentage growth.

•

Reported GAAP net loss of $4.2 million and adjusted net loss of $0.7 million.

•

Delivered adjusted EBITDA of $2.1 million, the second consecutive quarter of positive adjusted EBITDA.

•

Generated $4.4 million in operating cash flow in the second quarter of 2025, strengthening quarter-end cash, cash equivalents, marketable securities and restricted cash to $123.7 million.

•

Introduced Voxi™ 5, a new stationary oxygen concentrator (SOC) designed to improve access to quality oxygen therapy for long-term care patients in the U.S., further expanding the portfolio.

•

Launched Inogen Patient Portal, designed to empower patients with seamless self-service to manage insurance details, order accessories and access to on-demand support tools.

“We are executing a compelling turnaround strategy, delivering six consecutive quarters of mid-single-digit revenue growth and two quarters of positive adjusted EBITDA,” said Kevin Smith, President and Chief Executive Officer. “Our 4% year-over-year revenue growth in the second quarter reflects the strength of our commercial execution and operational enhancements. Given our strong first-half performance, we are raising full-year revenue guidance. We remain confident in our long-term value creation strategy as we continue to drive innovation and position Inogen as a leader in comprehensive respiratory care.”

Second Quarter 2025 Financial Results

Total revenue in the second quarter of 2025 was $92.3 million, an increase of 4.0% from the prior-year period, as a result of continued higher demand from international and domestic business-to-business customers. This increase was partially offset by lower direct-to-consumer and rental revenue.

Total gross margin in the second quarter of 2025 was 44.8% compared to 48.1% in the prior-year period, primarily the result of increased business-to-business sales as a percentage of total revenue.

Total operating expense in the second quarter of 2025 was $47.5 million, a decrease of 4.7% from $49.8 million in the prior-year period, primarily due to a one-time bad debt expense in the prior year.

GAAP net loss in the second quarter of 2025 was $4.2 million compared to $5.6 million in the prior-year period, while adjusted net loss in the second quarter of 2025 was $0.7 million, an improvement of $0.9 million from adjusted net loss of $1.6 million in the prior-year period.

Adjusted EBITDA in the second quarter of 2025 was $2.1 million compared to $1.3 million in the prior-year period.

Cash, cash equivalents, marketable securities, and restricted cash were $123.7 million as of June 30, 2025, with no debt outstanding.

Reconciliations of adjusted EBITDA and adjusted net loss for the three months ended June 30, 2025 and 2024 are provided 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.”

Full Year and Third Quarter 2025 Financial Outlook

For the full year 2025, Inogen now expects reported revenue in the range of $354 million to $357 million, reflecting approximately 6% growth at the midpoint of the range, relative to the Company’s 2024 revenue, and now expects to reach Adjusted EBITDA breakeven.

For the third quarter of 2025, Inogen expects reported revenue in the range of $91 million to $93 million, reflecting approximately 4% year-over-year growth at the midpoint of the range, relative to the Company’s third quarter 2024 revenue.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this communication that are not historical facts, including, but not limited to, statements regarding Inogen’s future business plans, market opportunities, financial outlook, growth strategies, and anticipated operational results, are forward-looking statements. Words such as “aims,” “believes,” “anticipates,” “plans,” “expects,” “will,” “intends,” “potential,” “possible,” and similar expressions are intended to identify forward-looking statements. Forward-looking statements are subject to numerous risks and uncertainties that could cause actual results to differ materially from currently anticipated results, including but not limited to, risks and uncertainties relating to Inogen’s third quarter and full year financial guidance; market acceptance of its products; competition; its sales, marketing and distribution capabilities; its planned sales, marketing, and research and development activities; and risks associated with international operations. Information on these and additional risks, uncertainties, and other information affecting Inogen’s business operating results are contained in its Annual Report on Form 10-K for the period ended December 31, 2024, and in its other filings with the Securities and Exchange Commission. These forward-looking statements speak only as of the date hereof. Inogen disclaims any obligation to update these forward-looking statements except as may be required by law.

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, 2025, and June 30, 2024, including EBITDA; adjusted EBITDA; adjusted operating expense; adjusted loss from operations; adjusted net loss; and adjusted diluted EPS. Management believes that 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 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.
