On or after the Effective Date, as a non-employee director and pursuant to the Company's Amended and Restated 2023 Equity Incentive Plan and the Policy, Mr. Jamali will receive an initial award of restricted stock units ("RSUs") covering a number of shares having a grant date fair value of $180,000. Each RSU represents a contingent right to receive one share of the Company's Common Stock. The award will vest on the earlier of (i) the one-year anniversary of the date of the grant and (ii) the day prior to the date of the Company's 2027 annual meeting of stockholders, subject to Mr. Jamali continuing to serve as a director through the vesting date.

Mr. Jamali will enter into the Company's standard indemnification agreement for directors and officers, a copy of which was attached as Exhibit 10.1 to the Company's Registration Statement on Form S-1 (File No. 333-192605) filed with the Securities and Exchange Commission on November 27, 2013.

Mr. Jamali is a long-time medical device executive who will bring added depth and expertise to the Board. During his tenure as the Chief Executive Officer of ZimVie, he led the company's Nasdaq listing following the spin-out from Zimmer Biomet and helped each of the businesses (Spine and Dental) through significant portfolio optimization actions to support a turnaround to higher growth and profitability. Prior to ZimVie, most notably, he spent nearly twelve years at Covidien and Medtronic, where he most recently served as Senior Vice President and President of the Respiratory, Gastrointestinal & Informatics division, a $3 billion business that included 10,000 team members across four businesses and 14 manufacturing sites. While leading that division, he played a key role in accelerating growth and expanding margins.

"We are pleased to welcome Vafa to the Board and look forward to benefiting from his unique perspectives," said Beth Mora, Chairperson of the Board. "Throughout his many years of leading medical device companies, Vafa has established a track record of driving strategic execution and delivering sustained growth. As we continue advancing our transformation from a single product oxygen company into a diversified respiratory care platform, we believe Vafa's insight and direction will help guide our management team to execute on its path forward and continue to deliver strong top-line growth and improve profitability."

"Inogen is well positioned to drive meaningful growth, supported by its strong foundation in portable oxygen and an expanded, diversified product portfolio, as healthcare systems continue to shift care into the home," said Mr. Jamali. "The Company's clear strategic direction and improved financial profile provide a solid foundation for the opportunities ahead, and I look forward to working closely with the Board and management to help guide Inogen's continued progress."

"We invested in Inogen because we believe the Company's innovative respiratory product portfolio is uniquely positioned to address growing and unmet patient needs. As Inogen executes on profitable growth, more patient lives are enhanced and the broader healthcare system benefits," said Benjamin Natter, Managing Member of Kent Lake. "Our recent discussions with the Company have reinforced our confidence in the direction Inogen is taking, and we believe Vafa will be a constructive addition to the Board as management continues to execute on its established strategic priorities of driving organic revenue growth, advancing profitability and cash generation, continued product innovation, and disciplined capital allocation."

In connection with Mr. Jamali's appointment, the Company has entered into a cooperation agreement with Kent Lake Partners LP, Kent Lake PR LLC and Benjamin Natter (collectively, "Kent Lake"). The agreement includes customary standstill, voting, and other provisions. The agreement will be filed by the Company with the U.S. Securities and Exchange Commission as an exhibit to a Current Report on Form 8-K.
