The Company’s tax expense benefited from its operations in lower tax jurisdictions, such as Switzerland, research tax credits, the recognition of excess tax benefits related to share-based compensation and from an intra-entity assignment of intangible assets that received a tax basis step-up. The Company's tax expense increased due to disallowed transaction costs, goodwill impairments, change in the valuation allowance and an increase in global intangible low-taxed income ("GILTI"), driven by the capitalization of R&D costs as mandated by the Tax Cuts and Jobs Act (the "Tax Act").

On December 6, 2016, the Company was granted a tax holiday ("Tax Holiday") with an effective date of January 30, 2017. The Tax Holiday provides Semtech (International) AG with a 70% reduction to the Swiss Cantonal tax rate, bringing the statutory Swiss Cantonal tax rate down from 12.56% to 3.77%. The maximum benefit under this Tax Holiday is CHF 500.0 million of cumulative after tax profit, which equates to a maximum potential tax savings of CHF 44.0 million. The Tax Holiday was effective for five years and could be extended for an additional five years if the Company met certain staffing targets by January 30, 2022. Semtech (International) AG has met these staffing guidelines, and therefore, the tax holiday is extended for an additional five years ending January 31, 2027.

On May 19, 2019, Switzerland approved the Federal Act on Tax Reform ("Swiss Tax Reform"). One main component of the Swiss Tax Reform included reduction of Cantonal income tax rates. The Swiss Tax Reform dropped the statutory Swiss Cantonal tax rate down from 12.56% to 8.46%. Semtech’s Tax Holiday provides Semtech (International) AG with a 70% reduction to this new Swiss Cantonal tax rate, bringing the statutory Swiss Cantonal tax rate down from 8.46% to 2.54%. All other provisions of the existing Tax Holiday discussed above still apply.

On December 22, 2023, the Swiss Federal Council officially declared the entry into force of the Swiss implementation of the OECD’s Pillar Two rules beginning January 1, 2024, which imposes global minimum tax of 15% on multination enterprises with an annual revenue exceeding €750 million in at least two out of the last four years. The Company expects to meet the revenue thresholds requirement in fiscal year 2026, and these provisions will adversely impact our provision for income taxes.

The Creating Helpful Incentives to Produce Semiconductors and Science Act (“CHIPS Act”) provides for various incentives and tax credits, including the Advanced Manufacturing Investment Credit (“AMIC”), which equals 25% of qualified investments in an advanced manufacturing facility that is placed in service after December 31, 2022. At least a portion of our current and future capital expenditures and research and development costs will qualify for this credit, which benefits us by allowing us to net the credit received against our costs. The AMIC credit is accounted for outside of ASC 740 as a reduction to the depreciable basis of the assets used in operations and will not have an impact on our effective tax rate.

The Tax Act imposed a U.S. tax on GILTI income that is earned by certain foreign affiliates owned by a U.S. stockholder. In accordance with guidance issued by the FASB, the Company has made a policy election to treat future taxes related to GILTI as a current period expense in the reporting period in which the tax is incurred.

Prior to the enactment of the Tax Act, with few exceptions, U.S. federal income and foreign withholding taxes had not been provided on the excess of the amount for financial reporting over the tax basis of investments in the Company’s foreign subsidiaries that were essentially permanent in duration. With the enactment of the Tax Act, all historic and current foreign earnings are taxed in the U.S. Depending on the jurisdiction, these foreign earnings are potentially subject to a withholding tax, if repatriated. As of January 28, 2024, the historical undistributed earnings of the Company’s foreign subsidiaries are intended to be permanently reinvested outside of the U.S.

Notwithstanding the U.S. taxation of these amounts, the Company has determined that none of its current foreign earnings will be permanently reinvested. If the Company needed to remit all or a portion of its historical undistributed earnings to the U.S. for investment in its domestic operations, any such remittance could result in increased tax liabilities and a higher effective tax rate. Determination of the amount of the unrecognized deferred tax liability on these unremitted earnings is not practicable.

As of January 28, 2024, the Company had U.S. gross federal and state research credits available of approximately $10.8 million and $24.4 million, respectively, which are available to offset taxable income. In connection with the Sierra Wireless Acquisition, the Company acquired approximately $6.6 million of fully reserved U.S. research credit carryforwards. The Company's U.S. credits will expire between fiscal years 2029 through 2044. The Company also had gross Canadian research credits available of approximately $44.2 million. Included in the $44.2 million are $32.4 million of Canadian research credit carryforwards that were acquired in connection with the Sierra Wireless Acquisition. The Company's Canadian credits will expire by fiscal year 2044.

As of January 28, 2024, the Company had U.S. gross federal net operating loss ("NOL") carryforwards of $80.3 million and state NOL carryforwards of $131.1 million, which, subject to certain limitations, are available to offset future taxable income through fiscal year 2044. The federal NOL carryforwards are primarily NOLs acquired in the Sierra Wireless Acquisition. These will expire at various dates through 2038 for losses generated prior to tax year 2018. For losses generated during tax year 2018 and future years, the NOL carryforward period is indefinite, but the loss utilization will be limited to 80% of taxable income. A portion of these losses may be subject to annual limitations due to ownership change provisions under Section 382 of the Internal Revenue Code ("IRC"). This limitation may result in the expiration of NOLs before utilization.

Additionally, the Company had fully reserved gross NOLs in Canada and France, for $40.0 million and $264.1 million respectively, for companies acquired during the Sierra Wireless Acquisition. The Company also has a gross Swiss NOL of $17.5 million, and a gross UK NOL of $4.1 million.

As of January 28, 2024 and January 29, 2023, the Company had approximately $321.5 million and $215.6 million of net deferred tax assets, respectively, the majority of which are in the U.S., Canada and France. The Company has recorded valuation allowances of $304.4 million and $156.9 million against its deferred tax assets at January 28, 2024 and January 29, 2023, respectively, based on the Company's assessment of its ability to utilize its deferred tax assets. The large increase in

valuation allowance was mainly due to the Sierra Wireless Acquisition (discussed in Note 3). In connection with the acquisition, the Company reassessed the valuation allowances and evaluated the recoverability of its deferred tax assets, considering all available evidence such as earnings history and tax planning strategies. After weighing all positive and negative evidence, the Company maintains a valuation allowance for assets if it is more likely than not that some, or all, of its deferred tax assets will not be realized. Positive evidence considered included reversing taxable temporary differences. Negative evidence considered included the cumulative pre-tax losses recorded during the three-year period ended January 28, 2024, on both an annual and cumulative basis. In jurisdictions where the Company has cumulative losses, the Company has recorded a full valuation allowance on deferred tax assets. As of January 28, 2024, the Company continues to maintain full valuation allowance on DTAs in the U.S. and France, as well as a partial valuation allowance on DTAs in Canada.

During the second quarter of fiscal year 2024, the Company determined utilization of its net DTAs in the U.S. was limited, and accordingly recorded an increase to its valuation allowance reserve of $52.8 million. This determination was made after evaluating both the positive and negative evidence regarding the recoverability of the Company’s net U.S. DTAs. Significant negative evidence that led to this conclusion included substantial cumulative GAAP financial losses, goodwill impairment (as discussed in Note 8, Goodwill and Intangible Assets), and in the absence of additional actions, the Company's inability to maintain compliance with the financial covenants over the next twelve months from the issuance of the accompanying interim unaudited condensed consolidated financial statements.

The current year additions of $147.5 million primarily consists of valuation allowance on deferred tax assets related to purchased intangibles, disallowed interest expense carried forward under IRC section 163j ("Section 163j") and other U.S. deferred taxes. The change in the valuation allowance related to the Convertible Note Hedge Transactions of $1.7 million is included in the Statements of Stockholders' Equity (Deficit). The change in the valuation allowance for Section 163j and state deferred taxes of $149.2 million is included in the fiscal year 2024 provision for income taxes in the Consolidated Statements of Operations.

The Company uses a two-step approach to recognize and measure uncertain tax positions ("UTP"). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

Included in the balance of gross unrecognized tax benefits at January 28, 2024 and January 29, 2023, are $14.6 million and $12.6 million, respectively, of net tax benefits (after federal impact of state items) that, if recognized, would impact the effective tax rate. The Company believes that it is reasonably possible that its balance of gross unrecognized tax benefits may decrease by approximately $16 million within the next twelve months due to expiration of statute.

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits within the provision for taxes in the Statements of Operations. The Company had approximately $2.8 million of net interest and penalties accrued at January 28, 2024.

Tax years prior to 2013 (the Company’s fiscal year 2014) are generally not subject to examination by the IRS except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. For state returns in the U.S., the Company is generally not subject to income tax examinations for years prior to 2012 (the Company’s fiscal year 2013). The Company has a significant tax presence in Switzerland for which Swiss tax filings have been examined through fiscal year 2020. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.
