Non-GAAP Financial Measures

The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with U.S. GAAP. The non-GAAP financial measures presented exclude the items described below. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results. Furthermore, management also believes that these items are not indicative of the Company's on-going operating performance. These non-GAAP financial measures have certain limitations in that they do not reflect all of the costs associated with the operations of the Company's business as determined in accordance with GAAP.

Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by the Company may be different from the non-GAAP financial measures used by other companies.

The Company has presented the following non-GAAP measures to assist investors in understanding the Company's net operating results on an on-going basis (i) constant currency product revenue growth %, (ii) non-GAAP net income, (iii) non-GAAP (net income) earnings per diluted share and (iv) non-GAAP operating income margin. These non-GAAP financial measures may also assist investors in making comparisons of the Company's operating results with those of other companies. Management believes constant currency product revenue growth, non-GAAP operating income margin, non-GAAP net income and non-GAAP earnings per diluted share are important measures in the evaluation of the Company's performance and uses these measures to better understand and evaluate our business.

The non-GAAP financial measures reflect adjustments for the following items, as well as the related income tax effects thereof

Constant currency revenue adjustments

Some of our sales agreements with foreign customers provide for payment in currencies other than the U.S. Dollar. These foreign currency revenues, when converted into U.S. Dollars, can vary significantly from period-to-period depending on the average and quarter-end exchange rates during a respective period. We believe that comparing these foreign currency denominated revenues by holding the exchange rates constant with the prior year period is useful to management and investors in evaluating our product revenue growth rates on a period-to-period basis. We anticipate that fluctuations in foreign exchange rates and the related constant currency adjustments for calculation of our product revenue growth rate will continue to occur in future periods.

Royalty and other revenue, net of related costs

We derive royalty and other revenue, net of related costs, from certain non-recurring contractual arrangements that we do not expect to continue in the future. We believe the exclusion of royalty and other revenue, net of related costs, associated with these non-recurring revenue streams is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis.

Acquisition, integration and related costs

These transactions represent gains, losses, and other related costs associated with acquisitions, integrations, investments and divestitures. These items also include but are not limited to amortization and depreciation of intangible assets, asset impairments, and in-process research and development. We believe that the exclusion of these items is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis.

Litigation related expenses, settlements and awards

These transactions represent gains, losses, and other related costs associated with certain litigation matters, which can vary in their characteristics, frequency and significance to our operating results. We believe that the exclusion of these items is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis.

In the event there are gains, losses and other adjustments which impact period-to-period comparability and do not represent the underlying ongoing results of the business, the Company may choose to exclude these from non-GAAP earnings.

Realized and unrealized gains or losses

These transactions represent gains, losses, and other related costs associated with foreign currency denominated transactions and investments. As the Company does not actively hedge these currency exposures, changes in the underlying currency rates relative to the U.S. Dollar may result in realized and unrealized foreign currency gains and losses between the time these receivables and payables arise and the time that they are settled in cash. Unrealized and realized gains and losses on investments may impact the Company's reported results of operations for a period. These items are highly variable, difficult to predict and outside the control of those responsible for the underlying operations of the business. We believe that exclusion of these items is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis.

Tax impact of non-GAAP adjustments

In order to reflect the tax effected impact of the non-GAAP adjustments, the Company will adjust the non-GAAP earnings by the approximate tax impact of these adjustments.

Excess tax benefits from stock-based compensation expense

GAAP requires that excess tax benefits recognized on stock-based compensation expense be reflected in our provision for income taxes rather than paid-in capital. As these excess tax benefits may be highly variable from period-to-period, the Company may choose to exclude these tax benefits from non-GAAP earnings to facilitate comparability between periods and with peers.

Masimo (Nasdaq MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. Our mission is to improve patient outcomes, reduce the cost of care and take noninvasive monitoring to new sites and applications. Masimo SET Measure-through Motion and Low Perfusion pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies. Masimo SET has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates, improve CCHD screening in newborns, and, when used for continuous monitoring with Masimo Patient SafetyNet in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs. Masimo SET is estimated to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world, and is the primary pulse oximetry at 9 of the top 10 hospitals as ranked in the 2021-22 U.S. News and World Report Best Hospitals Honor Roll. Masimo continues to refine SET and in 2018, announced that SpO2 accuracy on RD SET sensors during conditions of motion has been significantly improved, providing clinicians with even greater confidence that the SpO2 values they rely on accurately reflect a patient's physiological status. In 2005, Masimo introduced rainbow Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb ), oxygen content (SpOC ), carboxyhemoglobin (SpCO ), methemoglobin (SpMet ), Pleth Variability Index (PVi ), RPVi (rainbow PVi), and Oxygen Reserve Index (ORi ). In 2013, Masimo introduced the Root 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 Brain Function Monitoring, O3 Regional Oximetry, and ISA Capnography with NomoLine sampling lines. Masimo's family of continuous and spot-check monitoring Pulse CO-Oximeters includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7 and Radius PPG , portable devices like Rad-67 , fingertip pulse oximeters like MightySat Rx, and devices available for use both in the hospital and at home, such as Rad-97 . Masimo hospital automation and connectivity solutions are centered around the Masimo Hospital Automation platform, and include Iris Gateway, iSirona , Patient SafetyNet, Replica , Halo ION , UniView , UniView 60 , and Masimo SafetyNet .
