The information in this Current Report on Form 8-K is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, regardless of any general incorporation language in such filing, except as expressly set forth by reference in such filing.

Forward-Looking Statements

This filing contains "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, as amended, based on the Company's current expectations, estimates and projections about its operations, industry, financial condition, performance, results of operations, and liquidity. Forward-looking statements are statements other than historical information or statements of current condition and relate to matters such as future financial performance including the third quarter of fiscal year 2027 outlook and a financial framework for fiscal year 2030; future operational performance; the anticipated impact of specific items on future earnings; the Company's expectations regarding near term growth trends and market position; and the Company's plans, objectives and expectations. Statements containing words such as "may," "believes," "see," "anticipates," "expects," "intends," "positions," "plans," "projects,“ “targets,” "objectives,"

"estimates," "develops," "should," "could," "will," "designed to," "projections," or "outlook," or other similar expressions constitute forward-looking statements.

Forward-looking statements involve known and unknown risks and uncertainties that could cause actual results and events to differ materially from those projected. Potential factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: the volatility of our financial results or impact of the cyclical nature of our industry, including due to growing concentration of demand in artificial intelligence-related semiconductors, during industry downturns or due to periodic economic uncertainty; the historical rapid decrease of the average selling prices of certain products; disruptions in U.S. or foreign government operations, funding or incentives; changes in export restrictions and laws affecting the Company's trade and investments, including tariffs or retaliatory tariffs; interruption or loss of supplies or services from the limited number of suppliers and subcontractors we rely upon; our suppliers' manufacturing capacity constraints or other supply chain disruptions; failure to successfully develop and sell new products, meet new industry standards or requirements or anticipate changes in projected or end market users; failure to adequately protect our intellectual property rights; failure to make the substantial investments in research and development that are required to remain competitive in our business or to properly anticipate competitive changes in the marketplace; the likelihood of our products being found defective or risk of liability claims asserted against us; business interruptions, such as natural disasters, acts of violence and the outbreak of contagious diseases; adverse changes to general economic conditions in China; the loss of any one of our small number of customers or failure to collect a receivable from them; competition from new or established IoT, cloud services and wireless service companies or from those with greater resources; the difficulties associated with integrating ours and Sierra Wireless, Inc.'s businesses and operations successfully as well as difficulties executing other acquisitions or divestitures, including the pending divestiture of our cellular module business and attendant risks; discovery of additional material weaknesses in our internal control over financial reporting in the future or otherwise failing to achieve and maintain effective disclosure controls, procedures and internal control over financial reporting; changes in our effective tax rates, the adoption of new U.S. or foreign tax legislation or exposure to additional tax liabilities, or material differences between our forecasted annual effective tax rates and actual tax rates; the Company's ability to comply with, or pursue business strategies due to, our level of indebtedness or the covenants under the agreements governing our indebtedness; and adverse developments affecting the financial services industry. Additionally, forward-looking statements should be considered in conjunction with the cautionary statements contained in the risk factors disclosed in the Company's filings with the Securities and Exchange Commission (the "SEC"), including the Company's Annual Report on Form 10-K for the fiscal year ended January 25, 2026, filed with the SEC on March 23, 2026 as such risk factors may be amended, supplemented or superseded from time to time by other reports the Company files with the SEC. In light of the significant risks and uncertainties inherent in the forward-looking information included herein that may cause actual performance and results to differ materially from those predicted, any such forward-looking information should not be regarded as representations or guarantees by the Company of future performance or results, or that its objectives or plans will be achieved or that any of its operating expectations or financial forecasts will be realized. Reported results should not be considered an indication of future performance. Investors are cautioned not to place undue reliance on any forward-looking information contained herein, which reflect management's analysis only as of the date hereof. These forward-looking statements speak only as of the date hereof. Except as required by law, the Company assumes no obligation to publicly release the results of any update or revision to any forward-looking statement that may be made to reflect new information, events or circumstances after the date hereof or to reflect the occurrence of unanticipated or future events, or otherwise.

Disclosure Regarding Financial Framework

The FY30 financial framework consists of targets and goals, not guidance or forecasts, and is not a guarantee of future performance. It is forward-looking, is based on management’s current assumptions and expectations as of October 15, 2026, and is subject to significant risks and uncertainties, as discussed in Forward-Looking Statements above, in particular with respect to the growth of the data center market and the Company’s ability to capture it. Actual results may differ materially.

Non-GAAP Financial Measures

Adjusted gross margin, adjusted operating margin, adjusted gross margin, excluding business held for sale, adjusted diluted earnings per share, adjusted normalized tax rate and free cashflow as a percentage of net sales are non-GAAP financial measures. They supplement, and should not be considered a substitute for, measures prepared in accordance with GAAP, and they may not be comparable to similarly titled measures used by other companies. Definitions of these measures, the items they exclude, and reconciliations to the most comparable GAAP measures are included in Semtech's Earnings Release on Form 8-K for the second quarter of fiscal year 2027 filed with the SEC on August 25, 2026.

The Company is unable to include a reconciliation of forward-looking non-GAAP results to the corresponding GAAP measures as they are not available without unreasonable efforts due to the high variability and low visibility with respect to the impact of transaction, integration and restructuring expenses, share-based awards, amortization of acquisition-related intangible assets and other items that are excluded from these non-GAAP measures. The Company expects the variability of the above charges to have a potentially significant impact on its GAAP financial results.
