These forward-looking statements speak only as of the date of this press release, and MACOM undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Discussion Regarding the Use of Historical and Forward-Looking Non-GAAP Financial Measures

In addition to United States Generally Accepted Accounting Principles ("GAAP") reporting, MACOM provides investors with financial measures that have not been calculated in accordance with GAAP, such as: non-GAAP gross profit and gross margin, non-GAAP operating expenses, non-GAAP income (loss) from operations and operating margin, adjusted EBITDA, non-GAAP net income, non-GAAP diluted earnings per share, non-GAAP diluted shares, non-GAAP income tax rate, non-GAAP interest expense and free cash flow. In this release or elsewhere, we may alternatively refer to such non-GAAP measures as “adjusted” measures. This non-GAAP information excludes the effect, where applicable, of intangible amortization expense, share-based and non-cash compensation expense, impairment and restructuring charges, changes in common stock warrant liability, non-cash interest, acquisition and integration related costs, equity investment gains and losses and the tax effect of each non-GAAP adjustment.

Management believes these excluded items are not reflective of our underlying performance and uses these non-GAAP financial measures to: evaluate our ongoing operating performance and compare it against prior periods, make operating decisions, forecast future periods, evaluate potential acquisitions, compare our operating performance against peer companies and assess certain compensation programs. The exclusion of these items from our non-GAAP financial results should not be interpreted as implying that these items are non-recurring, infrequent or unusual. We believe this non-GAAP financial information provides additional insight into our ongoing performance and have therefore chosen to provide this information to investors to help them evaluate the results of our ongoing operations and enable more meaningful period-to-period comparisons. These non-GAAP measures are provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release. We have not provided a reconciliation with respect to any forward-looking non-GAAP financial data presented because we do not have and cannot reliably estimate certain key inputs required to calculate the most comparable GAAP financial data, such as the future price per share of our common stock for purposes of calculating the value of our common stock warrant liability, future acquisition costs, the possibility and impact of any litigation costs, changes in our GAAP effective tax rate and impairment charges. We believe these unknown inputs are likely to have a significant impact on any estimate of the comparable GAAP financial data.

Investors are cautioned against placing undue reliance on non-GAAP financial measures and are urged to review and consider carefully the adjustments made by management to the most directly comparable GAAP financial measures. Non-GAAP financial measures may have limited value as analytical tools because they may exclude certain expenses that some investors consider important in evaluating our operating performance or ongoing business performance. Further, non-GAAP financial measures may have limited value for purposes of drawing comparisons between companies because different companies may calculate similarly titled non-GAAP financial measures in different ways because non-GAAP measures are not based on any comprehensive set of accounting rules or principles.

Additional information and management’s assessment regarding why certain items are excluded from our non-GAAP measures are summarized below:

Amortization Expense - is related to acquired intangible assets which are based upon valuation methodologies, and are generally amortized over the expected life of the intangible asset at the time of acquisition, which may result in amortization amounts that vary over time. This is a non-cash expense and is not considered by management in making operating decisions.

Share-Based and Non-cash Compensation Expense - includes share-based compensation expense for awards that are equity and liability classified on our balance sheet. Share-based compensation expense is partially outside of our control due to factors such as stock price volatility and interest rates, which may be unrelated to our operating performance during the period in which the expense is incurred. It is an expense based upon valuation methodologies and assumptions that vary over time, and the amount of the expense can vary significantly between companies. Share-based and non-cash compensation expense amounts are not considered by management in making operating decisions.

Restructuring Charges - includes amounts primarily associated with our 2019 restructuring plan that reduced staffing and manufacturing, research and development and administrative footprints. We believe these amounts are not correlated to future business operations and including such charges does not reflect our ongoing operations.

Warrant Liability Expenses/Gains - are associated with mark-to-market fair value adjustments which are largely based on the value of our common stock, which may vary from period to period due to factors such as stock price volatility. We believe these amounts are not correlated to future business operations and including such charges does not reflect our ongoing operations.

Non-cash Interest, Net - includes amounts associated with the amortization of certain fees associated with the establishment or amendment of our credit agreement and term loans that are being amortized over the life of the agreement. We believe these amounts are non-cash in nature and not correlated to future business operations and including such charges does not reflect our ongoing operations.

Acquisition and Integration Related Costs - includes amounts accrued for employees of acquired businesses which are not expected to have a continuing contribution to operations. We believe the exclusion of these items is useful in providing management a basis to evaluate ongoing operating activities and strategic decision making.

Equity Investment Gains and Losses - primarily includes gains and losses associated with a non-marketable equity investment we have in a private business. The investment losses are non-cash in nature and we believe

these items are not correlated to future business operations and including such amounts does not reflect our ongoing operations.

Tax Effect of Non-GAAP Adjustments - includes adjustments to arrive at an estimate of our adjusted non-GAAP income tax rate associated with our adjusted non-GAAP income over a period of time. We determine our adjusted non-GAAP income tax rate by using applicable rates in taxing jurisdictions and assessing certain factors including our historical and forecast earnings by jurisdiction, discrete items, cash taxes paid in relation to our adjusted non-GAAP net income before income taxes and our ability to realize tax assets. We generally assess this adjusted non-GAAP income tax rate quarterly and have utilized 5% for fiscal year 2021 and 8% for fiscal year 2020. Our historical effective income tax rate under GAAP has varied significantly from our adjusted non-GAAP income tax rate due primarily to changes in fair values of the common stock warrant liability, which are excluded from our adjusted net income and are neither deductible nor taxable for tax purposes, losses or gains associated with our equity method investment in a private business, income taxed in foreign jurisdictions at generally lower tax rates, intangible impairments, research and development tax credits and merger expenses. We believe it is beneficial for management to review our adjusted non-GAAP income tax rate on a consistent basis over periods of time. Items such as those noted above may have a significant impact on our GAAP income tax expense and associated effective tax rate over time.

Adjusted EBITDA - is a calculation that adds depreciation expense to our adjusted income from operations. Management reviews and utilizes this measure for operational analysis purposes. We believe competitors and others in the financial industry also utilize this measure for analysis purposes.

Free Cash Flow - is a calculation that starts with cash flow from operating activities and reduces this amount by our capital expenditures in the applicable period. Management reviews and utilizes this measure for cash flow analysis purposes. We believe competitors and others in the financial industry also utilize this measure for analyzing a company’s cash flow.

Incremental Shares - is the number of potential shares of common stock issuable upon the exercise of stock options, restricted stock, restricted stock units and warrants that were not included in the calculation of our GAAP diluted shares. We believe competitors and others in the financial industry utilize this measure for analysis purposes.
