About PolitanOur NomineesThird Party PerspectivesImportant MaterialsContact Us Bring Needed Change to Masimo’s BoardPolitan, a 8.9% owner of Masimo, is fully aligned with the success of the Company and long-term value creation for the benefit of all shareholders. That is why Politan has nominated two ideally-qualified director candidates – Michelle Brennan and Quentin Koffey – for election to the Board at the 2023 AGM. Michelle Brennan Quentin Koffey MEET OUR NOMINEES

Masimo Is an Extreme Outlier: Poor Governance Resulting in a Discounted Valuation Shareholders have understandably lost confidence in the stewardship of Masimo’s Board Substantial market value drop after M&A Collapse in Valuation • Masimo’s market value declined by $5+B upon announcing its $1B acquisition of Sound United • The decline in value is an extraordinary outlier: At 5x the purchase price, the drop is 19x the standard deviation seen in US public markets following a deal. In fact, the second largest decline in the past decade was 1.6x the purchase price. • This drastic loss of value reflects more than customary concerns about a controversial deal – it reveals a crisis of governance, as investors believe there is no oversight of management. • This $4+B valuation discount – approximately 40% of the Company’s current market capitalization – persists today.

Exceptionally high director withhold votes Persistent Governance Failures “Better governance doesn’t drive better stock price.” - Michael Cohen, Masimo Lead Director • Masimo ranks in the bottom fifth percentile of the entire Russell 3000 for votes against directors over the past decade. • Masimo is the only public company in the US with a market valuation above $5B with no independent leadership, a staggered board and five or fewer directors. • The Company has failed to meet prior commitments made to shareholders – it refused to comply with its 2015 governance agreement to expand the Board to seven directors.

Longstanding Say on Pay failures Egregious Compensation & Side Payments • Masimo ranks in the bottom one percentile of the entire Russell 3000 for “Say-on-Pay” and has failed its Say-on-Pay vote for six of the last twelve years. • The CEO’s compensation is over 1.6x peers and 2.6x peers as a percentage of revenue. • The Board has permitted a variety of related party payments to Mr. Kiani, including paying $17M/year in royalties to Cercacor (owned and controlled by Mr. Kiani) and permitting Mr. Kiani to use the Masimo Foundation as a personal foundation (with his wife and sister comprising the majority of the foundation’s board for most of its history).

Excessive change of control payment Unprecedented Special Payments • Masimo’s change in control payment of $600+M for Mr. Kiani is 54x the peer median and in the top 0.1 percentile of S&P1500 companies. • More extreme is the fact that the payment is triggered even if there is no change in control, but instead if there is simply independent leadership of the Board appointed or shareholders elect to change 1/3rd of the Board. Effectively, Mr. Kiani’s employment agreement means Masimo’s Board is permanently staggered. We believe it is illegal and as part of ongoing litigation, Masimo had to waive application of this extreme payment for the 2023 annual meeting. • CalSTRS joined Politan in challenging the employment agreement in court, stating “CalSTRS has been a Masimo stockholder for more than a decade... The Masimo CEO’s employment agreement is not only counter to the best interests of the Company’s stockholders, but also sets a dangerous precedent. Ultimately, good governance drives greater value and that is why we are joining this lawsuit.”

“This is not just about Politan being able to nominate directors at MASI, it is about shareholder rights and the future of shareholder activism – we do not believe it is an overstatement to say that the entire concept of corporate democracy rests on the outcome of this case.” Unending Entrenchment Tactics • Less than one week after management’s first meeting with Politan, Masimo’s Board adopted advance notice bylaws designed to disenfranchise shareholders by making it extremely difficult – if not outright impossible – for Politan, or any other investment fund shareholder, to nominate directors for election to the Masimo Board. • Despite the bylaws receiving waves of intense criticism from governance experts across both sides of the investor / company aisle, Masimo’s Board defended the bylaws and only removed them once Mr. Kiani’s compensation plan was put at risk due to the litigation.

Third Party Perspectives “Kiani's contract is not in the best interest of investors and ‘sets a dangerous precedent,’ Aeisha Mastagni, CalSTRS Portfolio Manager of Sustainable Investment and Stewardship Strategies said… Judge Nathan Cook called the potential payout to Kiani an ‘astounding amount.’” California teachers pension fund joins Politan's legal fight against Masimo “US companies with the court’s backing have increasingly been free to create hoops for dissident investors to jump through before waging proxy contests. But the set of requirements Masimo is seeking to impose has the investment and legal community wondering if this time corporate America has pushed the envelope too far.” The Wall Street fight that has echoes of the cold war “This is not just about Politan being able to nominate directors at MASI, it is about shareholder rights and the future of shareholder activism – we do not believe it is an overstatement to say that the entire concept of corporate democracy rests on the outcome of this case.” Marginalizing Activist Shareholders Indefinitely “When you’ve found a corporate defense that makes Wachtell uneasy, you’ve overshot…The Delaware court has to balance two things: giving corporate managers the freedom to run their business, and ensuring accountability and reasonable access to the ballot for shareholders. This bylaw will kill the latter, and goes too far in the tug-of-war between management and shareholders.” A fight for the boardroom of America “Masimo apparently capitulated and completely undid its bylaw amendments to 'moot' the lawsuit, said Kai Liekefett, who defends corporations against activist investors as co-chair of law firm Sidley Austin's shareholder activism and corporate defense practice.” Masimo reverses bylaws requiring detailed activist information READ MORE
