Effective October 2, 2023, Mark Lin became Semtech's executive vice president and chief financial officer

Semtech Corporation (NASDAQ:SMTC), a high-performance semiconductor, IoT systems and cloud connectivity service provider, today reported unaudited financial results for its third quarter of fiscal year 2024, which ended October 29, 2023.

"While recognizing ongoing constraints in our hardware business and effects of elevated channel inventories, we noted stabilization of end market demand for our semiconductor business," said Paul H. Pickle, Semtech's president and chief executive officer. "Notably, end market demand in the third quarter for high-end consumer and data center applications has grown both sequentially and year-over-year."

"We continue to optimize our cost structure with non-GAAP operating expenses and non-GAAP interest expense each forecasted to sequentially improve in the fourth quarter," said Mark Lin, Semtech's executive vice president and chief financial officer. "Our recent change in capital structure further provides us with flexibility to address near-term challenges from the current economic environment."

The fourth quarter of fiscal year 2024 outlook incorporates the Company's current estimates, as well as its expectations regarding the impact of export restrictions, inflationary pressure and other macroeconomic conditions. The Company is unable to predict the full impact such challenges may have on its future results of operations.

The Company is unable to include a reconciliation of the forward-looking non-GAAP results to the corresponding GAAP measures as this is 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 gross margin, SG&A expense, R&D expense, operating costs and expenses, net, operating income or loss, operating margin, interest expense, net, diluted (loss) earnings per share, and normalized tax rate exclude the following items, if any, 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 (including costs associated with the acquisition of Sierra Wireless)
Restructuring and other reserves, including cumulative other reserves associated with historical activity including environmental and pension
Litigation costs or dispute settlement charges or recoveries
Gain on sale of business
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
Debt commitment fee
Goodwill impairment
Amortization of inventory step-up

Effective as of the third quarter of fiscal year 2024, the Company's non-GAAP measures have been adjusted to exclude amortization of deferred financing costs, which had the impact of decreasing non-GAAP interest expense, net and increasing non-GAAP net income or loss attributable to common stockholders and non-GAAP earnings or loss per diluted share. This adjustment was applied retrospectively and all prior period amounts have been revised to conform to the current presentation.

To provide additional insight into the Company's fourth quarter outlook, this release also includes a presentation of forward-looking non-GAAP financial measures. In the financial statements provided with this release, the Company also presents Adjusted EBITDA and free cash flow. Adjusted EBITDA is defined as net (loss) income plus interest expense, interest income, 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. The Company considers free cash flow, which may be positive or negative, a non-GAAP financial measure defined as cash flows provided by (used in) 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 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.

The financial statements provided with this release include reconciliations of these non-GAAP financial measures to their most comparable GAAP measures for the second and third quarters of fiscal year 2024 and the third quarter of fiscal year 2023. 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 2024, the Company's projected non-GAAP normalized tax rate is 12% and will be applied to each quarter of fiscal year 2024. 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.
