including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. In addition, Masimo Consumer
Audio is home to eight legendary audio brands, including Bowers &amp; Wilkins, Denon, Marantz, and Polk Audio. Our mission is to improve
life, improve patient outcomes, and reduce the cost of care. Masimo SET<SUP>&reg;</SUP>&nbsp;Measure-through Motion and Low Perfusion&trade;
pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.<SUP>1</SUP>&nbsp;Masimo
SET<SUP>&reg;</SUP>&nbsp;has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,<SUP>2</SUP>&nbsp;improve
CCHD screening in newborns<SUP>3&nbsp;</SUP>and, when used for continuous monitoring with Masimo Patient SafetyNet&trade; in post-surgical
wards, reduce rapid response team activations, ICU transfers, and costs.<SUP>4-7&nbsp;</SUP>Masimo SET<SUP>&reg;</SUP>&nbsp;is estimated
to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world,<SUP>8</SUP>&nbsp;and
is the primary pulse oximetry at 9 of the top 10 hospitals as ranked in the 2022-23&nbsp;<I>U.S. News and World Report</I>&nbsp;Best
Hospitals Honor Roll.<SUP>9</SUP>&nbsp;In 2005, Masimo introduced rainbow<SUP>&reg;</SUP>&nbsp;Pulse CO-Oximetry technology, allowing
noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin
(SpHb<SUP>&reg;</SUP>), oxygen content (SpOC&trade;), carboxyhemoglobin (SpCO<SUP>&reg;</SUP>), methemoglobin (SpMet<SUP>&reg;</SUP>),
Pleth Variability Index (PVi<SUP>&reg;</SUP>), RPVi&trade; (rainbow<SUP>&reg;</SUP>&nbsp;PVi), and Oxygen Reserve Index (ORi&trade;).
In 2013, Masimo introduced the Root<SUP>&reg;</SUP>&nbsp;Patient Monitoring and Connectivity Platform, built from the ground up to be
as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo
additions include Next Generation SedLine<SUP>&reg;</SUP>&nbsp;Brain Function Monitoring, O3<SUP>&reg;</SUP>&nbsp;Regional Oximetry,
and ISA&trade; Capnography with NomoLine<SUP>&reg;</SUP>&nbsp;sampling lines. Masimo&rsquo;s family of continuous and spot-check monitoring
Pulse CO-Oximeters<SUP>&reg;</SUP>&nbsp;includes devices designed for use in a variety of clinical and non-clinical scenarios, including
tetherless, wearable technology, such as Radius-7<SUP>&reg;</SUP>, Radius PPG<SUP>&reg;</SUP>, and Radius VSM&trade;, portable devices
like Rad-67<SUP>&reg;</SUP>, fingertip pulse oximeters like MightySat<SUP>&reg;</SUP>&nbsp;Rx, and devices available for use both in
the hospital and at home, such as Rad-97<SUP>&reg;</SUP>&nbsp;and the Masimo W1<SUP>&reg;</SUP>&nbsp;medical watch. Masimo hospital and

press release includes forward-looking statements as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E
of the Securities Exchange Act of 1934, as amended, in connection with the Private Securities Litigation Reform Act of 1995. These forward-looking
statements include, among others, statements regarding the 2024 Annual Meeting of Stockholders (the &ldquo;2024 Annual Meeting&rdquo;)
of Masimo and the potential stockholder approval of the Board&rsquo;s nominees. These forward-looking statements are based on current
expectations about future events affecting Masimo and are subject to risks and uncertainties, all of which are difficult to predict and
many of which are beyond Masimo&rsquo;s control and could cause its actual results to differ materially and adversely from those expressed
in its forward-looking statements as a result of various risk factors, including, but not limited to (i) uncertainties regarding future
actions that may be taken by Politan in furtherance of its nomination of director candidates for election at the 2024 Annual Meeting,
(ii) the potential cost and management distraction attendant to Politan&rsquo;s nomination of director nominees at the 2024 Annual Meeting
and (iii) factors discussed in the &ldquo;Risk Factors&rdquo; section of Masimo&rsquo;s most recent periodic reports filed with the Securities
and Exchange Commission (&ldquo;SEC&rdquo;), which may be obtained for free at the SEC&rsquo;s website at www.sec.gov. Although Masimo
believes that the expectations reflected in its forward-looking statements are reasonable, the Company does not know whether its expectations
will prove correct. All forward-looking statements included in this press release are expressly qualified in their entirety by the foregoing
cautionary statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of today&rsquo;s
date. Masimo does not undertake any obligation to update, amend or clarify these statements or the &ldquo;Risk Factors&rdquo; contained
in the Company&rsquo;s most recent reports filed with the SEC, whether as a result of new information, future events or otherwise, except
as may be required under the applicable securities laws.</FONT></P>
