On September 29, 2026, Inogen, Inc. (the “Company”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Rotech Healthcare Inc. (the “Buyer”), pursuant to which the Company agreed to sell to the Buyer substantially all of the assets used or held for use solely in the operation of the Company’s United States oxygen rental business, including specified on-rent and on-hand inventory and related patient records (the “Transaction”). The aggregate purchase price is estimated at up to approximately $24.8 million based on the inventory and patient records to be transferred and is subject to post-closing reconciliation, and payable in six installments. The Transaction is subject to customary closing conditions.

Item 7.01. Regulation FD Disclosure.

On September 30, 2026, the Company issued a press release announcing the execution of the Purchase Agreement and a separate product supply agreement with Rotech Healthcare Inc., together with the conditional amendment to the Company’s existing share repurchase program described in Item 8.01 below. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information in this Item 7.01, including Exhibit 99.1, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01. Other Events

On September 28, 2026, the Company’s Board of Directors approved an amendment to the Company’s existing share repurchase program. The Company's existing share repurchase program was originally authorized by the Board of Directors on February 20, 2026 and provides for the repurchase of up to $30.0 million of the Company’s common stock, exclusive of fees, commissions and other expenses, through December 31, 2027. The amendment is conditioned upon, and will become effective only upon, the closing of the Transaction.

Upon the closing of the Transaction, the amendment will increase the aggregate repurchase authorization from $30.0 million to $45.0 million, exclusive of fees, commissions and other expenses, and extend the program’s expiration date from December 31, 2027 to June 30, 2028. The $45.0 million authorization represents the total amount authorized under the program, including all repurchases previously made under the program, and is not an incremental authorization. All other terms of the existing program will remain unchanged.

If the Transaction is not consummated, the amendment will not become effective, and the current terms of the existing share repurchase program will remain in effect.

Exhibit 99.1

INOGEN ANNOUNCES DIVESTITURE OF ITS U.S. OXYGEN

RENTAL BUSINESS TO ROTECH

Transaction advances Inogen’s strategic shift toward a more streamlined commercial model supporting higher revenue growth and adjusted operating income

BEVERLY, Mass., September 30, 2026 -- Inogen, Inc. (Nasdaq: INGN), a medical technology company offering innovative respiratory products for use in the homecare setting, today announced that it has signed a definitive agreement to divest its U.S. oxygen rental business to Rotech Healthcare, a leading national provider of home respiratory and medical equipment. Under the agreement, Rotech will acquire specified rental assets for a total estimated cash consideration of up to $25 million. The transaction is expected to close in the fourth quarter of 2026, subject to customary closing conditions.

Separately, Inogen also signed a new, long-term supply agreement with Rotech, which is expected to support accelerating patient demand and access to Inogen’s oxygen concentrators through Rotech’s national distribution network.

Following these transactions, Inogen will operate through a simpler, more focused business model designed to drive greater patient access, faster growth and improved profitability. The Company will continue to leverage its core competencies in respiratory innovation, while partnering with leading home medical equipment providers to expand the number of patients using Inogen products. Inogen remains committed to supporting patients, healthcare providers and distributors, with patients continuing to have access to Inogen products through both distributors and its cash-pay direct-to-consumer sales channel.

“These transactions strengthen our business and financial profile, sharpen our strategic focus, and enable us to continue investing in innovative solutions that improve patient outcomes,” said Kevin Smith, President and Chief Executive Officer of Inogen. “Rotech’s strong reputation and respiratory care expertise makes it a proven and trusted partner for our patients. Together, we are focused on providing a smooth transition for patients and ensuring continued access to high-quality oxygen therapy solutions.”

Expected Financial Impact

Inogen expects the transactions to increase both the revenue growth rate and adjusted operating income. The Rental Business generated revenue of $24.3 million in the first half of 2026, representing a year-over-year decline of 9.8%. Beginning with its financial results for the third quarter of 2026, Inogen expects to present the Rental Business as discontinued operations, subject to completion of the Company’s final accounting analysis. In connection with its third-quarter earnings report, the Company expects to provide additional information regarding the historical financial results of the Rental Business and the impact of the transactions on Inogen’s outlook for continuing operations.

Share Repurchase Authorization Increase

Subject to the closing of the transaction, Inogen’s Board of Directors has approved an increase of $15 million to the Company’s existing share repurchase authorization, bringing the total authorization to $45 million and further enhancing Inogen’s ability to return capital to shareholders. The expanded authorization will expire on June 30, 2028, or when the maximum authorized dollar amount has been

utilized, whichever occurs first. The Company is under no obligation to purchase a specific number of shares, and the program may be suspended or terminated at any time.
