Masimo Announces Leadership Transition

Katie Szyman Appointed Chief Executive Officer and to Board of Directors

Interim CEO Michelle Brennan Named Chairman of Masimo's Board

Today the Board of Directors (the "Board") of Masimo (NASDAQ:MASI), a leading global medical innovator, announced that Katie Szyman has been appointed the next Chief Executive Officer ("CEO") of the Company. Interim CEO Michelle Brennan has been appointed Chairman of Masimo's Board and Lead Independent Director Quentin Koffey has been appointed Vice Chairman. All of these changes are effective as of February 12, 2025.

Ms. Szyman is currently worldwide president of Advanced Patient Monitoring at BD (Becton, Dickinson and Company). Previously, Ms. Szyman led the Critical Care product group at Edwards Lifesciences ("Edwards"), which was acquired by BD in a transaction that closed in September of 2024. Her appointment follows an extensive search process overseen by the Board with the assistance of executive recruitment firm Korn Ferry. During this process, the Board evaluated numerous internal and external candidates. The Board concluded that Ms. Szyman was the right choice given her successful track record of accelerating revenue growth by bringing new patient monitoring products to market, extensive experience leading and retaining top industry talent, and deep existing relationships within the sector.

While at Edwards, Ms. Szyman significantly accelerated revenue growth in the Critical Care product group through numerous successful initiatives, including entering adjacent markets through internal and external innovation and introducing the first AI technology cleared by the Food and Drug Administration in the patient monitoring space. She possesses significant operational and financial leadership experience that will aid Masimo as it continues to address its cost structure and improve gross margin performance. Ms. Szyman also brings public company board experience, including serving as a director of Inari Medical since 2019.

Mr. Koffey stated:

"Katie's more than 35 years of relevant experience and her unique mix of expertise set her apart during our search and make her an ideal fit to lead the next innovation-focused stage of Masimo's evolution. We also want to thank Michelle for her exemplary performance in the interim CEO role, particularly in leading a seamless transition for customers, employees and shareholders from day one. We look forward to continuing to benefit from her experience and judgment as she moves into her new position as Chairman of the Board."

Ms. Brennan added:

"We wanted our next CEO to be someone who is passionate about the role and inspiring as well as engaging the team at Masimo – and Katie made clear that she is that person. Her advanced patient monitoring category knowledge and deep existing relationships within the industry position her to make an immediate impact as she works with the Board on prioritizing our pipeline to focus on large opportunities, while developing a clear strategy for bringing our next generation patient monitoring platform to market."

Ms. Szyman commented:

"I have long admired Masimo as an innovation leader, and I could not be more excited about the opportunity to grow the business and deliver improved outcomes for millions more patients around the world. I believe Masimo's leadership team and bench of talent is top tier, and I am thrilled by the chance to work with and learn from this group."

The Board remains committed to the previously announced review of alternatives for both the consumer audio and consumer healthcare businesses and has engaged Centerview Partners and Morgan Stanley as financial advisors and Sullivan & Cromwell as a legal advisor. The Board looks forward to providing updates in the near-term regarding value-creation initiatives, including this strategic review.
