These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These statements involve risks and uncertainties that could cause our actual results to differ materially, including, but not limited to: any continued economic uncertainty due to the impact of the COVID-19 pandemic, monetary policy, political, geopolitical, trade or other issues in the U.S. or internationally, any further unexpected fluctuations or weakness in the U.S. and global economies (including China), changes in demand or market acceptance of our products and the products of our customers; our ability to successfully integrate the operations and employees, retain key employees and customers and otherwise realize the expected synergies and benefits of our acquisitions; the impact of current and future changes in U.S. corporate tax laws (including the Tax Cuts and Jobs Act of 2017), foreign currency effects on our business; the mix of inventory we hold and our ability to satisfy short-term orders from our inventory; changes in utilization of our manufacturing capacity and our ability to effectively manage and expand our production levels; competitive developments including pricing pressures; the level of orders that are received and can be shipped in a quarter; changes or fluctuations in customer order patterns and seasonality; the impact of any future significant acquisitions that we may make; our ability to obtain a sufficient supply of wafers from third party wafer foundries and the cost of such wafers, the costs and outcome of any current or future litigation or other matters involving our Microsemi acquisition, the Microsemi business, intellectual property, customers, or other issues; the costs and outcome of any current or future tax audit or investigation regarding our business or the business of Microsemi, our actual average stock price in the December 2020 quarter and the impact such price will have on our share count; fluctuations in our stock price and trading volume which could impact the number of shares we acquire under our share repurchase program and the timing of such repurchases; disruptions in our business or the businesses of our customers or suppliers due to natural disasters (including any floods in Thailand), terrorist activity, armed conflict, war, worldwide oil prices and supply, public health concerns (including the COVID-19 pandemic) or disruptions in the transportation system; and general economic, industry or political conditions in the United States or internationally.

For a detailed discussion of these and other risk factors, please refer to Microchip's filings on Forms 10-K and 10-Q. You can obtain copies of Forms 10-K and 10-Q and other relevant documents for free at Microchip's website (www.microchip.com) or the SEC's website (www.sec.gov) or from commercial document retrieval services. You are cautioned not to place undue reliance on our forward-looking statements, which speak only as of the date such statements are made. Microchip does not undertake any obligation to publicly update any forward-looking statements to reflect events, circumstances or new information after the date of this presentation or to reflect the occurrence of unanticipated events.

Use of Non-GAAPFinancial Measures: In this presentation, we have included certain non-GAAP financial information, including for example, adjusted EBITDA, non-GAAP gross profit and free cash flow. We also disclose information about our end-market demand metric. Our non-GAAP results, where applicable, exclude the effect of share-based compensation, COVID-19shelter-in-place restrictions on manufacturing activities, expenses related to our acquisition activities (including intangible asset amortization, inventory valuation costs, excess capacity charges to normalize acquired inventory levels, severance and other restructuring costs, and legal and other general and administrative expenses associated with acquisitions including legal fees and expenses for litigation and investigations related to our Microsemi acquisition), professional services associated with certain legal matters, IT security remediation costs, non-cash interest expense on our convertible debentures, losses on the settlement of debt, and gains and losses related to available-for-sale investments. For the fourth quarters of fiscal 2020 and fiscal 2019, our non-GAAP income tax expense is presented based on projected cash taxes for the fiscal year, excluding transition tax payments under the Tax Cuts and Jobs Act. Following our required adoption of the new revenue recognition standard effective April 1, 2018, we disclose "end market demand" which is the net dollar amount of our products, licensing revenue and other services delivered to our direct (non-distributor) customers and by our distributors to their customers. Our determination of our non-GAAP measures might not be the same as similarly titled measures used by other companies, and it should not be construed as a substitute for amounts determined in accordance with GAAP. There are limitations associated with using non-GAAP measures, including that they exclude financial information that some may consider important in evaluating our performance. Management compensates for this by presenting information on both a GAAP and non-GAAP basis for investors and providing reconciliations of the GAAP and non-GAAP results. Non-GAAP measures should not be considered in isolation or as an alternative to net income, cash from operations or other measures of profitability, liquidity or performance under GAAP. These non-GAAP and GAAP results are included in the appendix to this presentation. Certain supplemental information and reconciliations are available on our website at www.microchip.com/investorsunder the heading "Supplemental Financial Information".
