CAMARILLO, Calif., May 26, 2026—Semtech Corporation (Nasdaq: SMTC), a leading provider of high-performance semiconductors powering data center networking, Internet of Things ("IoT") connectivity and cellular infrastructure solutions, announced today unaudited financial results for its first quarter of fiscal year 2027, which ended April 26, 2026.

"Semtech is off to an exceptional start in fiscal year 2027, delivering record quarterly results and expanding design wins across our data center and LoRa businesses," said Hong Hou, president and chief executive officer. "As FiberEdge and CopperEdge 1.6T revenues layer onto our strong growth base, we expect data center growth to accelerate throughout the year. The strength and depth of our bookings and backlog, a broad and well-positioned product portfolio, and targeted R&D investments aligned to customer roadmaps give us strong conviction in our growth trajectory ahead."

"We demonstrated meaningful operating leverage in the first quarter," said Mark Lin, executive vice president and chief financial officer. "Our strong operational fundamentals provide a foundation for the improving metrics reflected in our second quarter outlook, and we expect this momentum to drive increasing shareholder returns."

*See "Non-GAAP Financial Measures" below for additional information about our non-GAAP financial results.

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.

Non-GAAP Financial Measures

To supplement the Company's consolidated financial statements prepared in accordance with GAAP, this release includes a presentation of select non-GAAP financial measures. The Company's non-GAAP measures of adjusted gross margin, total semiconductor products gross margin, adjusted product development and engineering expense, adjusted selling, general and administrative expense, adjusted operating expenses, net, adjusted operating income, adjusted operating margin, adjusted interest (income) expense, net, adjusted net income, adjusted diluted earnings per share, adjusted normalized tax rate, adjusted EBITDA and adjusted EBITDA margin exclude the following items, if any and as applicable, as set forth in the reconciliations in the tables below under "Supplemental Information: Reconciliation of GAAP to Non-GAAP Results."

•Share-based compensation

•Intangible amortization

•Transaction and integration related costs or recoveries

•Restructuring and other reserves, including cumulative other reserves associated with historical activity including environmental, pension, deferred compensation and right-of-use asset impairments

•Litigation costs or dispute settlement charges or recoveries

Semtech Announces First Quarter of Fiscal Year 2027 Results

•Equity method income or loss

•Investment gains, losses, reserves and impairments, including interest income from debt investments

•Write-off and amortization of deferred financing costs

•Interest rate swap termination

•Induced conversion expense

•Loss on extinguishment of debt

•Debt commitment fee

•Goodwill and intangible impairment

•Amortization of inventory step-up

In this release, the Company is providing a total semiconductor products gross margin metric, defined as the combined segment gross margin for the Signal Integrity and Analog Mixed Signal and Wireless reportable segments. For further information, please see the Segment Information footnote of the Company's Form 10-Q for the quarter ended April 26, 2026. The Company also presents adjusted EBITDA, adjusted EBITDA margin and free cash flow. Adjusted EBITDA is defined as net income (loss) plus interest expense, interest income, provision (benefit) for income taxes, depreciation and amortization, and share-based compensation, and adjusted to exclude certain expenses, gains and losses that the Company believes are not indicative of its core results over time. Adjusted EBITDA margin is defined as adjusted EBITDA as a percentage of net sales. The Company considers free cash flow, which may be positive or negative, a non-GAAP financial measure defined as cash flows provided by operating activities less net capital expenditures. Management believes that the presentation of these non-GAAP measures provides useful information to investors regarding the Company's financial condition and results of operations. These non-GAAP financial measures are adjusted to exclude the items identified above because such items are either operating expenses that would not otherwise have been incurred by the Company in the normal course of the Company's business operations, or are not reflective of the Company's core results over time. These excluded items may include recurring as well as non-recurring items, and no inference should be made that all of these adjustments, charges, costs or expenses are unusual, infrequent or non-recurring. For example: certain restructuring and integration-related expenses (which consist of employee termination costs, facility closure or lease termination costs, and contract termination costs) may be considered recurring given the Company's ongoing efforts to be more cost effective and efficient; certain acquisition and disposition-related adjustments or expenses may be deemed recurring given the Company's regular evaluation of potential transactions and investments; and certain litigation expenses or dispute settlement charges or gains (which may include estimated losses for which the Company may have established a reserve, as well as any actual settlements, judgments, or other resolutions against, or

Semtech Announces First Quarter of Fiscal Year 2027 Results

in favor of, the Company related to litigation, arbitration, disputes or similar matters, and insurance recoveries received by the Company related to such matters) may be viewed as recurring given that the Company may from time to time be involved in, and may resolve, litigation, arbitration, disputes, and similar matters.

Notwithstanding that certain adjustments, charges, costs or expenses may be considered recurring, in order to provide meaningful comparisons, the Company believes that it is appropriate to exclude such items because they are not reflective of the Company's core results and tend to vary based on timing, frequency and magnitude.

These non-GAAP financial measures are provided to enhance the user's overall understanding of the Company's comparable financial performance between periods. In addition, the Company's management generally excludes the items noted above when managing and evaluating the performance of the business. Certain non-GAAP financial measures are also used in the Company's compensation programs. The financial statements provided with this release include reconciliations of these non-GAAP financial measures to their most comparable GAAP measures for the first quarter of fiscal year 2027 and the first and fourth quarters of fiscal year 2026.

The Company adopted a full-year, normalized tax rate for the computation of the non-GAAP income tax provision in order to provide better comparability across the interim reporting periods by reducing the quarterly variability in non-GAAP tax rates that can occur throughout the year. In estimating the full-year non-GAAP normalized tax rate, the Company utilized a full-year financial projection that considers multiple factors such as changes to the Company's current operating structure, existing positions in various tax jurisdictions, the effect of key tax law changes, and other significant tax matters to the extent they are applicable to the full fiscal year financial projection. In addition to the adjustments described above, this normalized tax rate excludes the impact of share-based awards and the amortization of acquisition-related intangible assets. For fiscal year 2027, the Company's projected non-GAAP normalized tax rate is 17% and will be applied to each quarter of fiscal year 2027. The Company's non-GAAP normalized tax rate on non-GAAP net income may be adjusted during the year to account for events or trends that the Company believes materially impact the original annual non-GAAP normalized tax rate including, but not limited to, significant changes resulting from tax legislation, acquisitions, entity structures or operational changes and other significant events. These additional non-GAAP financial measures should not be considered substitutes for any measures derived in accordance with GAAP and may be inconsistent with similar measures presented by other companies.

To provide additional insight into the Company's second quarter outlook, this release also includes a presentation of forward-looking non-GAAP financial measures. See "Second Quarter of Fiscal Year 2027

Semtech Announces First Quarter of Fiscal Year 2027 Results

Outlook" above for further information.
