Fourth quarter 2023 revenue of $75.9 million; full-year 2023 revenue of $315.7 million

Inogen, Inc. (NASDAQ:INGN), a medical technology company offering innovative respiratory products for use in the homecare setting, today announced financial results for the fourth quarter and the full-year ended December 31, 2023.

"I am excited for the future of Inogen. As we progress into 2024, we are focused on positioning the business for revenue growth and long-term profitability while advancing our innovation pipeline and working to bring Physio-Assist to the U.S. market," said Kevin Smith, President and Chief Executive Officer. "We have a strong management team with the recent additions of Grégoire Ramade as Chief Commercial Officer and Michael Bourque as Chief Financial Officer, and we are confident in our ability to deliver value for shareholders."

Fourth Quarter 2023 Financial Results

Fourth quarter total revenue was $75.9 million, relative to $88.1 million in the fourth quarter of 2022, primarily due to a decrease in domestic business-to-business sales and direct-to-consumer sales, partially offset by higher rental revenue.

Total gross margin was 37.1% in the fourth quarter of 2023 versus 33.5% in the comparative period in 2022. The increase was driven primarily by lower premiums paid for components and labor and overhead costs.

Total operating expense for the quarter was $57.1 million compared to $88.0 million in the fourth quarter of 2022. The decrease was primarily due to the loss on disposal of an intangible asset of $52.2 million in the prior-year period, partially offset by the change in fair value of the earnout liabilities and certain one-time costs related to the CEO transition and bad debt expense.

GAAP net loss for the fourth quarter of 2023 was $26.6 million compared to GAAP net loss of $56.6 million in the fourth quarter of 2022. Adjusted net loss for the fourth quarter of 2023 was $19.4 million compared to adjusted net loss of $13.0 million in the fourth quarter of 2022.

Adjusted EBITDA was a negative $17.3 million in the fourth quarter of 2023 compared to a negative $10.6 million in the fourth quarter of 2022.

Cash, cash equivalents and marketable securities were $128.5 million as of December 31, 2023, with no debt outstanding.

Full-Year 2023 Financial Results

Total revenue was $315.7 million, compared to $377.2 million in 2022, primarily due to declines in direct-to-consumer sales as well as domestic and international business-to-business sales, partially offset by higher rental revenue.

Total gross margin was 40.1% for the full-year 2023 versus 40.7% in 2022. The decline was primarily due to sales channel mix and higher servicing costs, partially offset by lower premiums paid for components and labor and overhead costs as well as higher reimbursement rates. Additional impacts included higher cost of other materials and warranty cost per unit sold.

Total operating expense for the full-year 2023 was $236.1 million compared to $238.8 million for the full-year 2022.

GAAP net loss for full-year 2023 was $102.4 million compared to GAAP net loss of $83.8 million for full-year 2022. Adjusted net loss for full-year 2023 was $48.3 million compared to adjusted net loss of $26.2 million for full-year 2022.

Adjusted EBITDA was a negative $37.8 million for the full-year 2023 compared to a negative $13.5 million for the full-year 2022.

Reconciliations of adjusted EBITDA and adjusted net loss for the three and twelve months ended December 31, 2023 and 2022 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 "Non-GAAP Financial Measures."

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, among others, statements with respect to the business positioned for revenue growth and long-term profitability, advancing the innovation pipeline, working to bring Physio-Assist to the U.S. market, and Inogen's first quarter revenue expectations. Any statements contained in this communication that are not statements of historical fact may be deemed to be forward-looking statements. Words such as "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 related to its announced management and organizational changes, and risks arising from the possibility that Inogen will not realize anticipated future financial performance or strategic goals. In addition, Inogen's business is subject to numerous additional risks and uncertainties, including, among others, risks relating to market acceptance of its products; competition; its sales, marketing and distribution capabilities; its planned sales, marketing, and research and development activities; interruptions or delays in the supply of components or materials for, or manufacturing of, its products; seasonal variations; unanticipated increases in costs or expenses; risks associated with international operations; and the possibility that Inogen will not realize anticipated revenue from recent or future technology acquisitions or that expenses and costs related thereto will exceed Inogen's expectations. 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, 2023, its Quarterly Report on Form 10-Q for the calendar quarter ended September 30, 2023 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 twelve months ended December 31, 2023, and December 31, 2022. 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. For future periods, Inogen is unable to provide a reconciliation of non-GAAP measures without unreasonable effort as a result of the uncertainty regarding, and the potential variability of, the amounts of interest income, interest expense, depreciation and amortization, stock-based compensation, provision for income taxes, and certain other infrequently occurring items, such as acquisition-related costs, that may be incurred in the future.
