Included in the fourth quarter 2017 earnings per share was a non-recurring charge of $43.5 million, or $0.78 per diluted share, related to the Tax Cuts and Jobs Act of 2017 (2017 Tax Act) that was signed into law on December 22, 2017.

Supplementary Non-GAAP Financial Information

For additional non-GAAP financial details, please visit the Investor Relations section of the Company’s website at www.masimo.com to access Supplementary Financial Information.

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. generally accepted accounting principles (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 or that these items are not indicative of the Company’s on-going core 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 core net operating results on an on-going basis: (i) non-GAAP net income, (ii) non-GAAP diluted earnings per share, (iii) non-GAAP gross profit, (iv) non-GAAP operating income and (v) adjusted EBITDA. These non-GAAP financial measures may also assist investors in making comparisons of the Company’s core operating results with those of other companies. Management believes non-GAAP gross profit, non-GAAP operating income, non-GAAP net income, non-GAAP net income per diluted share and adjusted EBITDA 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:

Acquisition-related costs, including depreciation and amortization.

Depreciation and amortization related to the revaluation of assets and liabilities (primarily intangible assets, property, plant and equipment adjustments, inventory revaluation, lease liabilities, etc.) to fair value through purchase accounting related to value created by the seller prior to the acquisition rather than ongoing costs of operating our core business. As a result, we believe that exclusion of these costs in presenting non-GAAP financial measures provides management and investors a more effective means of evaluating historical performance and projected costs and the potential for realizing cost efficiencies within our core business. Depreciation and amortization related to the revaluation of acquisition related assets and liabilities will generally recur in future periods.

-2-

Litigation damages, awards and settlements.

In connection with litigation proceedings arising in the course of our business, we have recorded expenses as a defendant in such proceedings in the form of damages, as well as gains as a plaintiff in such proceedings in the form of litigation awards and settlement proceeds; most recently in connection with our November 2016 settlement agreement with Koninklijke Philips N.V. We believe that exclusion of these expenses and gains is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis. In this regard, we note that these expenses and gains are generally unrelated to our core business and/or infrequent in nature.

Excess tax benefits from stock-based compensation.

Accounting Standard Update No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), requires that excess tax benefits or costs recognized on stock-based compensation expense be reflected in our provision for income taxes rather than paid-in capital. Since we cannot control or predict when stock option awards will be exercised or the price at which such awards will be exercised, the impact of ASU 2016-09 can create significant volatility in our effective tax rate from one period to the next. We believe that exclusion of these excess tax benefits or costs is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis. These excess tax benefits or costs will generally recur in future periods as long as we continue to issue equity awards to our employees.

Tax impacts that may not be representative of the ongoing results of our core operations.

The 2017 Tax Act was signed into law in December 2017, and became effective January 1, 2018. The 2017 Tax Act included a number of changes to existing U.S. federal tax law impacting businesses including, among other things, a permanent reduction in the corporate income tax rate from 35% to 21%, a one-time transition tax on the “deemed repatriation” of cumulative undistributed foreign earnings as of December 31, 2017 and changes in the prospective taxation of the foreign operations of U.S. multinational companies. We believe that exclusion of the tax charges related to the 2017 Tax Act is useful to management and investors in evaluating the performance of our ongoing operations on a period-to-period basis. In this regard, we note that this tax charge is unrelated to our core business and non-recurring in nature.

About Masimo

Masimo (NASDAQ: MASI) is a global leader in innovative noninvasive monitoring technologies. Our mission is to improve patient outcomes and reduce the cost of care by taking noninvasive monitoring to new sites and applications. In 1995, the Company debuted Masimo SET^® Measure-through Motion and Low Perfusion^® pulse oximetry, which has been shown in multiple studies to significantly reduce false alarms and accurately monitor for true alarms. Masimo SET^® is estimated to be used on more than 100 million patients in leading hospitals and other healthcare settings around the world. 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^®) and more recently, Oxygen Reserve Index (ORi^™), in addition to SpO2, pulse rate and perfusion index (PI). In 2014, Masimo introduced Root^™, an intuitive patient monitoring and connectivity platform with the Masimo Open Connect^® (MOC-9^®) interface. Masimo is also taking an active leadership role in mobile health applications (mHealth) with products such as the Radius-7^® wearable patient monitor and the MightySat^™fingertip pulse oximeter. Additional information about Masimo and its products may be found at www.masimo.com.

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. generally accepted accounting principles (GAAP). The non-GAAP financial measures presented exclude the items that are more fully described below. Management believes that adjustments for these items assist investors in making comparisons of period-to- period operating results and that these items are not indicative of the company’s on-going core 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 core net operating results on an on-going basis: (i) non-GAAP net income, (ii) non-GAAP product revenue, (iii) non-GAAP gross profit, (iv) non-GAAP operating expenses, (v) non-GAAP non-operating income (expense), and (vi) non-GAAP net income per diluted share. These non- GAAP financial measures may also assist investors in making comparisons of the company’s core operating results with those of other companies. Management believes non-GAAP product revenue, non-GAAP gross profit, non-GAAP net income and non-GAAP net income 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: Acquisition-related depreciation and amortization, Excess tax benefits from stock-based compensation and Tax impacts that may not be representative of the ongoing results of our core operations.

All Rights Reserved. 2018 Financial Guidance1 1 Masimo 2018 financial guidance as of February 27, 2018 2 Please refer to our Non-GAAP financial measures and definitions contained herein ($ in millions, except per share amounts) 2018 Guidance Performance Highlights GAAP Non-GAAP 2 Total Revenue $ 836 $ 836 Product Revenue $ 808 $ 808 Reflects growth of approximately 9% over the prior year period Royalty and Other Revenue $ 28 $ 28 We expect approximately $3 million in Non-Recurring Engineering (NRE) revenues from our Philips partnership in 2018. Separately, with our royalty agreement expiring in October this year, we are projecting approximately $25 million in royalty revenue. Total Gross Margin 66.7% 66.8% ~30 basis points lower than prior year, which is primarily driven by a significant reduction in Royalty & NRE revenue which carry a higher margin than our product revenue. Product Gross Margin 65.7% 65.8% ~80 basis points higher than prior year. This is consistent with our goal of delivering at least 50 basis points of product gross margin improvement each year as we drive towards our long-term goal of 70% product gross margins.

The two items excluded are excess tax benefits from stock option exercises estimated at $0.12 offset by acquisition-related depreciation and amortization expense of $0.02 (net of tax), for a net adjustment of $0.10.
