Unless the context otherwise requires, the use of the terms "Semtech," "the Company," "we," "us" and "our" in this Quarterly Report on Form 10-Q refers to Semtech Corporation and, as applicable, its consolidated subsidiaries. This Quarterly Report on Form 10-Q may contain references to the Company’s trademarks and to trademarks belonging to other entities. Solely for convenience, trademarks and trade names referred to in this Quarterly Report on Form 10-Q, including logos, artwork and other visual displays, may appear without the ® or TM symbols, but such references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights or the rights of the applicable licensor to these trademarks and trade names. We do not intend our use or display of other companies' trade names or trademarks to imply a relationship with, or endorsement or sponsorship of us by, any other company.
Special Note Regarding Forward-Looking and Cautionary Statements
This Quarterly Report on Form 10-Q 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 our current expectations, estimates and projections about our 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, future operational performance, the anticipated impact of specific items on future earnings, and our plans, objectives and expectations. Statements containing words such as "may," "believe," "anticipate," "expect," "intend," "plan," "project," "estimate," "should," "will," "designed to," "projections," or "business 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 uncertainty surrounding the impact and duration of the COVID-19 pandemic on global economic conditions and on the Company’s business and results of operations; competitive changes in the marketplace including, but not limited to, the pace of growth or adoption rates of applicable products or technologies; downturns in the business cycle; decreased average selling prices of the Company’s products; the Company’s reliance on a limited number of suppliers and subcontractors for components and materials; changes in projected or anticipated end-user markets; export restrictions and laws affecting the Company’s trade and investments including with respect to Huawei and certain of its affiliates, and tariffs or the occurrence of trade wars; and the Company’s ability to forecast and achieve anticipated net sales and earnings estimates in light of periodic economic uncertainty, including impacts arising from Asian, European, and global economic dynamics.
Additionally, forward-looking statements should be considered in conjunction with the cautionary statements contained in this Quarterly Report on Form 10-Q, including, without limitation, information under the captions "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" and additional factors that accompany the related forward-looking statements in this Quarterly Report on Form 10-Q, in our Annual Report on Form 10-K for the fiscal year ended January 31, 2021 including, without limitation, information under the caption "Risk Factors," in our other filings with the U.S. Securities and Exchange Commission (“SEC”), and in material incorporated herein and therein by reference. 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. 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.
The factors noted above, and the risks included in our SEC filings, may be increased or intensified as a result of the COVID-19 pandemic. The extent to which the COVID-19 pandemic ultimately impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. In addition to regarding forward-looking statements with caution, you should consider that the preparation of the consolidated financial statements requires us to draw conclusions and make interpretations, judgments, assumptions and estimates with respect to certain factual, legal, and accounting matters. Our consolidated financial statements might have been materially impacted if we had reached different conclusions or made different interpretations, judgments, assumptions or estimates.

SEMTECH CORPORATION AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1: Organization and Basis of Presentation
Nature of Business
Semtech Corporation (together with its consolidated subsidiaries, the "Company" or "Semtech") is a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms. The end customers for the Company’s products are primarily original equipment manufacturers ("OEMs") that produce and sell electronics.
Fiscal Year
The Company reports results on the basis of 52 and 53-week periods and ends its fiscal year on the last Sunday in January. The other quarters generally end on the last Sunday of April, July and October, although the first and second quarters of fiscal year 2022 end on the first Sunday of May and August, respectively. All quarters consist of 13 weeks except for one 14-week period in the fourth quarter of 53-week years. The first quarters of fiscal years 2022 and 2021 each consisted of 13 weeks.
Principles of Consolidation
The accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company, in accordance with accounting principles generally accepted in the United States ("GAAP") and on the same basis as the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2021 ("Annual Report"). The Company’s interim unaudited condensed consolidated statements of income are referred to herein as the "Statements of Income." The Company’s interim unaudited condensed consolidated balance sheets are referred to herein as the "Balance Sheets" and interim unaudited condensed consolidated statements of cash flows as the "Statements of Cash Flows." In the opinion of the Company, these interim unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, the financial position of the Company for the interim periods presented. All intercompany balances have been eliminated. Because the interim unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for a complete set of consolidated financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in the Company's Annual Report. The results reported in these interim unaudited condensed consolidated financial statements should not be regarded as indicative of results that may be expected for any subsequent period or for the entire year.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recently Adopted Accounting Guidance
In December 2019, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2019-12, Simplifying the Accounting for Income Taxes, which modifies Accounting Standards Codification ("ASC") 740 to simplify the accounting for income taxes. This guidance impacts the accounting for hybrid tax regimes, the tax basis step-up in goodwill obtained in a transaction that is not a business combination, separate financial statements of legal entities not subject to tax, the intraperiod tax allocation exception to the incremental approach, ownership changes in investments from a subsidiary to an equity method investment and vice versa, interim period accounting for enacted changes in tax law and the year-to-date loss limitation in interim period tax accounting. This guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within this those fiscal years, with early adoption permitted. The Company adopted this guidance in the first quarter of fiscal year 2022. Adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

Note 2: Earnings per Share
The computation of basic and diluted earnings per common share was as follows:

| Three Months Ended |  |
(in thousands, except per share data) | May 2, 2021 |  | April 26, 2020 |  |  |  |
Net income attributable to common stockholders | $ | 23,500 |  |  | $ | 9,635 |  |  |  |  |
Weighted-average common shares outstanding–basic | 65,089 |  |  | 65,589 |  |  |  |  |
Dilutive effect of share-based compensation | 1,021 |  |  | 585 |  |  |  |  |
Weighted-average common shares outstanding–diluted | 66,110 |  |  | 66,174 |  |  |  |  |
Basic earnings per common share | $ | 0.36 |  |  | $ | 0.15 |  |  |  |  |
Diluted earnings per common share | $ | 0.36 |  |  | $ | 0.15 |  |  |  |  |
Anti-dilutive shares not included in the above calculations | — |  |  | 405 |  |  |  |  |

Diluted earnings per common share incorporates the incremental shares issuable, calculated using the treasury stock method, upon the assumed exercise of non-qualified stock options and the vesting of restricted stock units and market-condition restricted stock unit awards if certain conditions have been met, but excludes such incremental shares that would have an anti-dilutive effect.

Note 3: Share-Based Compensation
Financial Statement Effects and Presentation
Pre-tax share-based compensation was included in the Statements of Income as follows:

| Three Months Ended |  |
(in thousands) | May 2, 2021 |  | April 26, 2020 |  |  |  |
Cost of sales | $ | 718 |  |  | $ | 530 |  |  |  |  |
Selling, general and administrative | 7,359 |  |  | 5,959 |  |  |  |  |
Product development and engineering | 3,762 |  |  | 2,890 |  |  |  |  |
Total share-based compensation | $ | 11,839 |  |  | $ | 9,379 |  |  |  |  |

Restricted Stock Units, Employees
The Company grants restricted stock units to certain employees, which are expected to be settled with shares of the Company's common stock. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date, based on the fair value of the Company's common stock at the grant date, and recognized as share-based compensation expense over the requisite vesting period (typically 4 years). In the three months ended May 2, 2021, the Company granted 134,944 restricted stock units to employees.
Total Stockholder Return ("TSR") Market-Condition Restricted Stock Units
The Company grants TSR market-condition restricted stock units (the "TSR Awards") to certain executives of the Company. The TSR Awards have a pre-defined market-condition, which determines the number of shares that ultimately vest, as well as a service condition. The TSR Awards are valued as of the grant date using a Monte Carlo simulation which takes into consideration the possible outcomes pertaining to the TSR market condition and expense is recognized on a straight line basis over the vesting periods and is adjusted for any actual forfeitures.
In the three months ended May 2, 2021, the Company granted 81,688 TSR Awards, which are accounted for as equity awards. The market condition is determined based upon the Company’s TSR benchmarked against the TSR of the S&P SPDR Semiconductor ETF (NYSE:XSD) over one, two and three year periods (one-third of the awards vesting each performance period). Generally, the fiscal year 2022 award recipients must be employed for the entire performance period and be an active employee at the time of vesting of the awards. The grant-date fair value per unit of the awards granted in the three months ended May 2, 2021 for each one, two and three year performance period was $67.28, $83.94 and $95.52, respectively.
Market-Condition Restricted Stock Units
In the three months ended May 2, 2021, the Company granted 54,928 restricted stock units with a market condition. The awards are eligible to vest during the period commencing March 9, 2021, and ending May 5, 2024 (the "Performance Period") as follows: the restricted stock units covered by the award will vest if, during any consecutive 30 trading day period that commences and ends during the Performance Period, the average per-share closing price of the Company’s common stock equals or exceeds $95.00. The grant-date fair value per unit of the awards granted in the three months ended May 2, 2021 was $49.55.

The following table summarizes the maturities of the Company’s available-for-sale securities:

| May 2, 2021 |  |
(in thousands) | Fair Value |  | Amortized Cost |  |  |  |
Within 1 year | $ | 10,591 |  |  | $ | 11,041 |  |  |  |  |
After 1 year through 5 years | 1,012 |  |  | 1,875 |  |  |  |  |
Total available-for-sale securities | $ | 11,603 |  |  | $ | 12,916 |  |  |  |  |

The Company's available-for-sale securities consist of investments in convertible debt instruments issued by privately-held companies. The available-for-sale securities with maturities within one year were included in "Other current assets" and maturities greater than one year were included in "Other assets" in the Balance Sheets.

Note 5: Fair Value Measurements
The following fair value hierarchy is applied for disclosure of the inputs used to measure fair value and prioritizes the inputs into three levels as follows:
Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets and liabilities in active markets or other inputs that are observable for the assets or liabilities, either directly or indirectly.
Level 3—Unobservable inputs based on the Company’s own assumptions, requiring significant management judgment or estimation.
Instruments Measured at Fair Value on a Recurring Basis
The fair values of financial assets and liabilities measured and recorded at fair value on a recurring basis were presented in the Balance Sheets as follows:

| May 2, 2021 |  | January 31, 2021
(in thousands) | Total |  | (Level 1) |  | (Level 2) |  | (Level 3) |  | Total |  | (Level 1) |  | (Level 2) |  | (Level 3)
Financial assets: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Convertible debt | $ | 11,603 |  |  | $ | — |  |  | $ | — |  |  | $ | 11,603 |  |  | $ | 11,989 |  |  | $ | — |  |  | $ | — |  |  | $ | 11,989 |

Interest rate swap agreement | $ | 1,417 |  |  | $ | — |  |  | $ | 1,417 |  |  | $ | — |  |  | $ | 1,782 |  |  | $ | — |  |  | $ | 1,782 |  |  | $ | — |
Total return swap contracts | 12 |  |  | — |  |  | 12 |  |  | — |  |  | 167 |  |  | — |  |  | 167 |  |  | — |
Total financial liabilities | $ | 1,429 |  |  | $ | — |  |  | $ | 1,429 |  |  | $ | — |  |  | $ | 1,949 |  |  | $ | — |  |  | $ | 1,949 |  |  | $ | — |

During the three months ended May 2, 2021, the Company had no transfers of financial assets or liabilities between Level 1, Level 2 or Level 3. As of May 2, 2021 and January 31, 2021, the Company had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted.
The convertible debt investments are valued utilizing a combination of estimates that are based on the estimated discounted cash flows associated with the debt and the fair value of the equity into which the debt may be converted, all of which are Level 3 inputs.
The following table presents a reconciliation of the changes in the convertible debt investments in the three months ended May 2, 2021:

(in thousands) |  |
Balance at January 31, 2021 |  | $ | 11,989 |
Additions |  | 200 |
Increase in credit loss reserve |  | (246) |
Interest accrued |  | 286 |
Conversion to equity |  | (626) |
Balance at May 2, 2021 |  | $ | 11,603 |

The interest rate swap agreement is measured at fair value using readily available interest rate curves (Level 2 inputs). The fair value of the agreement is determined by comparing, for each settlement, the contract rate to the forward rate and discounting to the present value. Contracts in a gain position are recorded in "Other current assets" and "Other assets" in the Balance Sheets and the value of contracts in a loss position are recorded in "Accrued liabilities" and "Other long term liabilities" in the Balance Sheets. See Note 15 for further discussion of the Company’s derivative instruments.
The total return swap contracts are measured at fair value using quoted prices of the underlying investments (Level 2 inputs). The fair values of the total return swap contracts are recognized in the Balance Sheets in "Accrued Liabilities" if the instruments are in a loss position and in "Other Current Assets" if the instruments are in a gain position. See Note 15 for further discussion of the Company's derivative instruments.
13

Instruments Not Recorded at Fair Value on a Recurring Basis
Some of the Company’s financial instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents including money market deposits, net receivables, certain other assets, accounts payable, accrued expenses, accrued personnel costs, and other current liabilities. The Company’s long-term debt is recorded at cost, which approximates fair value as the long-term debt bears interest at a floating rate.
Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis
The Company reduces the carrying amounts of its goodwill, intangible assets, long-lived assets and non-marketable equity securities to fair value when held for sale or determined to be impaired.
Investment Impairments and Credit Loss Reserves
The total credit loss reserve for the Company's held-to-maturity debt securities and available-for-sale debt securities was $3.6 million and $3.4 million as of May 2, 2021 and January 31, 2021, respectively. During the three months ended May 2, 2021, the Company increased its expected credit loss reserves by $0.2 million, for its available-for-sale debt securities. Upon the adoption of ASU 2016-13 in the first quarter of fiscal year 2021, the Company recorded expected credit loss reserves of $0.4 million related to its held-to-maturity debt securities. During the three months ended April 26, 2020, the Company increased its expected credit loss reserves by $2.4 million for its held-to-maturity debt securities and available-for-sale debt securities. These increases were, in-part, due to the impact of the COVID-19 pandemic on early-stage development companies. During the three months ended April 26, 2020, the Company recorded $1.2 million of impairments on its non-marketable equity securities.

Note 6: Inventories
Inventories, consisting of material, material overhead, labor, and manufacturing overhead, are stated at the lower of cost (first-in, first-out) or net realizable value and consisted of the following:

(in thousands) | May 2, 2021 |  | January 31, 2021
Raw materials | $ | 3,566 |  |  | $ | 2,936 |
Work in progress | 67,192 |  |  | 59,523 |
Finished goods | 23,161 |  |  | 25,035 |
Inventories | $ | 93,919 |  |  | $ | 87,494 |

Note 7: Goodwill and Intangible Assets
Goodwill
The carrying amounts of goodwill by applicable reporting unit were as follows:

(in thousands) | Signal Integrity |  | Wireless and Sensing |  | Protection |  | Total
Balance at January 31, 2021 | $ | 274,085 |  |  | $ | 72,128 |  |  | $ | 4,928 |  |  | $ | 351,141 |
Balance at May 2, 2021 | $ | 274,085 |  |  | $ | 72,128 |  |  | $ | 4,928 |  |  | $ | 351,141 |

Goodwill is not amortized, but is tested for impairment at the reporting unit level using either a qualitative or quantitative assessment on an annual basis during the fourth quarter of each fiscal year, and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The recoverability of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value of the reporting unit. As of May 2, 2021, there was no indication of impairment of the Company's goodwill balances.
Purchased Intangibles
The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions and technology licenses purchased, which are amortized over their estimated useful lives:

|  |  | May 2, 2021 |  | January 31, 2021
(in thousands, except estimated useful life) | Estimated Useful Life |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Amount |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Amount
Core technologies | 3-8 years |  | $ | 29,300 |  |  | $ | (18,852) |  |  | $ | 10,448 |  |  | $ | 29,300 |  |  | $ | (17,554) |  |  | $ | 11,746 |

Note 8: Long-Term Debt
Long-term debt and the current period interest rates were as follows:

(in thousands, except percentages) | May 2, 2021 |  | January 31, 2021
Revolving loans | $ | 177,000 |  |  | $ | 181,000 |
Debt issuance costs | (1,684) |  |  | (1,805) |
Total long-term debt, net of debt issuance costs | $ | 175,316 |  |  | $ | 179,195 |
Effective interest rate (1) | 1.87 | % |  | 1.88 | %

(1) The revolving loans bear interest at a variable rate based on LIBOR or a Base Rate, at the Company’s option, plus an applicable margin that varies based on the Company’s consolidated leverage ratio. In the first quarter of fiscal year 2021, the Company entered into an interest rate swap agreement that fixed the interest on the first $150.0 million of debt outstanding under the revolving loans at 1.9775%. As of May 2, 2021, the effective interest rate is a weighted-average rate that represents interest on the first $150.0 million of the debt outstanding at a fixed LIBOR rate of 0.7275% plus a margin of 1.25% (total fixed rate of 1.9775%), and the remainder of the debt outstanding at a variable rate based on the one-month LIBOR rate, which was 0.12% as of May 2, 2021, plus a margin of 1.25% (total variable rate of 1.37%). As of January 31, 2021, the effective interest rate is a weighted-average rate that represents interest on the first $150.0 million of the debt outstanding at a fixed LIBOR rate of 0.7275% plus a margin of 1.25% (total fixed rate of 1.9775%), and the remainder of the debt outstanding at a variable rate based on the one-month LIBOR rate, which was 0.14% as of January 31, 2021, plus a margin of 1.25% (total variable rate of 1.39%).
On November 7, 2019, the Company, with certain of its domestic subsidiaries as guarantors, entered into an amended and restated credit agreement with the lenders party thereto and HSBC Bank USA, National Association, as administrative agent, swing line lender and letter of credit issuer. The borrowing capacity of the revolving loans under the senior secured first lien credit facility (the "Credit Facility") is $600.0 million and matures on November 7, 2024. As of May 2, 2021, the Company had $177.0 million outstanding under its Credit Facility, which had $423.0 million of undrawn borrowing capacity, and the Company was in compliance with the covenants required under the Credit Facility.
Interest expense was comprised of the following components for the periods presented:

| Three Months Ended |  |
(in thousands) | May 2, 2021 |  | April 26, 2020 |  |  |  |
Contractual interest (1) | $ | 1,078 |  |  | $ | 1,438 |  |  |  |  |
Amortization of debt discount and issuance costs | 121 |  |  | 121 |  |  |  |  |
Total interest expense | $ | 1,199 |  |  | $ | 1,559 |  |  |  |  |

(1) Contractual interest represents the interest on the Company's outstanding debt after giving effect to the interest rate swap agreement.
As of May 2, 2021, there were no amounts outstanding under the letters of credit, swing line loans and alternative currency sub-facilities.
17

Note 9: Income Taxes
The Company’s effective tax rate differs from the statutory federal income tax rate of 21% primarily due to the regional mix of income, excess tax benefits from share-based compensation and research and development tax credits.
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 in 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.
A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (before the federal impact of state items) is as follows:

(in thousands) |
Balance at January 31, 2021 | $ | 26,850 |
Additions/(decreases) based on tax positions related to the current fiscal year | 102 |
Additions/(decreases) based on tax positions related to the prior fiscal years | 36 |
Balance at May 2, 2021 | $ | 26,988 |

Included in the balance of gross unrecognized tax benefits at May 2, 2021 and January 31, 2021 are $9.8 million and $9.7 million, respectively, of net tax benefits (after the federal impact of state items), that, if recognized, would impact the effective tax rate, prior to consideration of any required valuation allowance.
The liability for UTP is reflected in the Balance Sheets as follows:

(in thousands) | May 2, 2021 |  | January 31, 2021
Deferred tax assets - non-current | $ | 15,817 |  |  | $ | 15,770 |
Other long-term liabilities | 9,819 |  |  | 9,731 |
Total accrued taxes | $ | 25,636 |  |  | $ | 25,501 |

The Company’s policy is to include net interest and penalties related to unrecognized tax benefits in the "Provision for income taxes" in the Statements of Income.
Tax years prior to 2013 (the Company’s fiscal year 2014) are generally not subject to examination by the U.S. Internal Revenue Service except for items involving tax attributes that have been carried forward to tax years whose statute of limitations remains open. For state returns, the Company is generally not subject to income tax examinations for calendar 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 2019. 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 audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits 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.
The Company’s regional income (loss) from continuing operations before taxes and equity in net gains of equity method investments was as follows:

| Three Months Ended |  |
(in thousands) | May 2, 2021 |  | April 26, 2020 |  |  |  |
Domestic | $ | (5,484) |  |  | $ | (6,978) |  |  |  |  |
Foreign | 32,102 |  |  | 17,980 |  |  |  |  |
Total | $ | 26,618 |  |  | $ | 11,002 |  |  |  |  |

Note 10: Leases
The Company has operating leases for real estate, vehicles, and office equipment. Real estate leases are used to secure office space for the Company's administrative, engineering, production support and manufacturing activities.

Note 11: Commitments and Contingencies
In accordance with ASC 450-20, Loss Contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. The Company also discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its consolidated financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company evaluates, at least quarterly, developments in its legal matters that could affect the amount of liability that has been previously accrued, and makes adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount. The Company may be unable to estimate a possible loss or range of possible loss due to various reasons, including, among others: (i) if the damages sought are indeterminate; (ii) if the proceedings are in early stages, (iii) if there is uncertainty as to the outcome of pending appeals, motions or settlements, (iv) if there are significant factual issues to be determined or resolved, and (v) if there are novel or unsettled legal theories presented. In such instances, there is considerable uncertainty regarding the ultimate resolution of such matters, including a possible eventual loss, if any.
Because the outcomes of litigation and other legal matters are inherently unpredictable, the Company’s evaluation of legal matters or proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved matters and proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. However, legal matters are inherently unpredictable and subject to significant uncertainties, some of which are beyond the Company’s control.
As such, even though the Company intends to vigorously defend itself with respect to its legal matters, there can be no assurance that the final outcome of these matters will not materially and adversely affect the Company’s business, financial condition, operating results, or cash flows.
From time to time, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to intellectual property, contract, product liability, employment, and environmental matters. In the opinion of management, after consulting with legal counsel, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole.
Environmental Matters
The Company vacated a former facility in Newbury Park, California in 2002, but continues to address groundwater and soil contamination at the site. The Company’s efforts to address site conditions have been at the direction of the Los Angeles Regional Water Quality Control Board (“RWQCB”). In October 2013, an order was issued including a scope of proposed additional site work, monitoring, and remediation activities. The Company has been complying with RWQCB orders and direction, and continues to implement an approved remedial action plan addressing the soil, groundwater, and soil vapor at the site.
The Company has accrued liabilities where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. Based on the latest determinations by the RWQCB and the most recent actions taken pursuant to the remedial action plan, the Company estimates the range of probable loss between $7.4 million and $8.0 million. To date, the Company has made $5.5 million in payments towards the remedial action plan and, as of May 2, 2021, has a remaining accrual of $1.9 million related to this matter. Given the uncertainties associated with environmental assessment and the remediation activities, the Company is unable to determine a best estimate within the range of loss. Therefore, the Company has recorded the minimum amount of probable loss. These estimates could change as a result of changes in planned remedial actions, further actions from the regulatory agency, remediation technology, and other factors.
Indemnification
The Company has entered into agreements with its current and former executives and directors indemnifying them against certain liabilities incurred in connection with the performance of their duties. The Company’s Certificate of Incorporation and Bylaws contain comparable indemnification obligations with respect to the Company’s current directors and employees.
Product Warranties
The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances, the Company has agreed to other or additional warranty terms, including indemnification provisions.
The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense and the related accrual has been immaterial to the Company’s consolidated financial statements.
Deferred Compensation
The Company maintains a deferred compensation plan for certain officers and key executives that allows participants to defer a portion of their compensation for future distribution at various times permitted by the plan. This plan provides for a discretionary Company match up to a defined portion of the employee's deferral, with any match subject to a vesting period.
The Company's liability for the deferred compensation plan is presented below:

(in thousands) | May 2, 2021 |  | January 31, 2021
Accrued liabilities | $ | 1,917 |  |  | $ | 1,709 |
Other long-term liabilities | 43,237 |  |  | 39,299 |
Total deferred compensation liabilities under this plan | $ | 45,154 |  |  | $ | 41,008 |

The Company has purchased whole life insurance on the lives of certain current deferred compensation plan participants. This Company-owned life insurance is held in a grantor trust and is intended to cover a majority of the Company's costs of the deferred compensation plan. The cash surrender value of the Company-owned life insurance was $29.6 million and $27.6 million as of May 2, 2021 and January 31, 2021, respectively, and is included in "Other assets" in the Balance Sheets.
Earn-out Liability
Pursuant to the terms of an amended earn-out arrangement ("Cycleo Earn-out") with the former shareholders of Cycleo SAS ("Cycleo Earn-out Beneficiaries"), which the Company acquired in March 2012, the Company must make payments based on the achievement of a combination of certain sales and operating income milestones over the period of April 27, 2015 to April 26, 2020. No payments have been made during fiscal years 2022 and 2021 for the remaining earn-out milestone. Any remaining payment for the earn-out is not expected to be material.

Outside Subcontractors and Suppliers
The Company relies on a limited number of third-party subcontractors and suppliers for the production of silicon wafers, packaging and certain other tasks. Disruption or termination of supply sources or subcontractors, including due to the COVID-19 pandemic or natural disasters such as an earthquake or other causes, have delayed and could delay shipments and could have a material adverse effect on the Company. Although there are generally alternate sources for these materials and services, qualification of the alternate sources could cause delays sufficient to have a material adverse effect on the Company. A significant amount of the Company’s third-party subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in the U.S., Taiwan and China. A significant amount of the Company’s assembly and test operations are conducted by third-party contractors in China, Malaysia, Taiwan, Thailand, South Korea and the Philippines.

Note 14: Stock Repurchase Program
The Company maintains a stock repurchase program that was initially approved by its Board of Directors in March 2008. The stock repurchase program does not have an expiration date and the Company’s Board of Directors has authorized expansion of the program over the years. The following table summarizes activity under the program for the presented periods:

| Three Months Ended |  |
| May 2, 2021 |  | April 26, 2020 |  |  |  |
(in thousands, except number of shares) | Shares |  | Amount Paid |  | Shares |  | Amount Paid |  |  |  |  |  |  |  |
Shares repurchased under the stock repurchase program | 360,942 |  |  | $ | 25,000 |  |  | 855,042 |  |  | $ | 30,000 |  |  |  |  |  |  |  |  |

On March 11, 2021, the Company's Board of Directors approved the expansion of the stock repurchase program by $350.0 million. As of May 2, 2021, the Company had repurchased $434.2 million in shares of its common stock under the program since inception and the remaining authorization under the program was $364.2 million. Under the program, the Company may repurchase its common stock at any time or from time to time, without prior notice, subject to market conditions and other considerations. The Company’s repurchases may be made through Rule 10b5-1 and/or Rule 10b-18 or other trading plans, open market purchases, privately negotiated transactions, block purchases or other transactions. The Company intends to fund repurchases under the program from cash on hand. The Company has no obligation to repurchase any shares under the program and may suspend or discontinue it at any time.
24

Note 15: Derivatives and Hedging Activities
The Company is exposed to certain risk arising from both its business operations and economic conditions and principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company, on a routine basis and in the normal course of business, experiences expenses denominated in Swiss Franc ("CHF"), Canadian Dollar ("CAD") and Great British Pound ("GBP"). Such expenses expose the Company to exchange rate fluctuations between these foreign currencies and the U.S. Dollar ("USD"). The Company occasionally uses derivative financial instruments, in the form of forward contracts, to mitigate a portion of the risk associated with adverse movements in these foreign currency exchange rates during a twelve-month window. Currency forward contracts involve fixing the exchange rate for delivery of a specified amount of foreign currency on a specified date. The Company’s accounting treatment for these instruments is based on whether or not the instruments are designated as a hedging instrument. As of May 2, 2021 and January 31, 2021, the Company had no outstanding foreign currency forward contracts.
During the first quarter of fiscal year 2021, the Company entered into an interest rate swap agreement with a three-year term to hedge the variability of interest payments on the first $150.0 million of debt outstanding under the Company's Credit Facility. Interest payments on $150.0 million of the Company's debt are now fixed at a rate of 1.9775%, based on the Company's current leverage ratio. The interest rate swap agreement has been designated as a cash flow hedge and unrealized gains or losses, net of income tax, are recorded as a component of "Accumulated Other Comprehensive Income or Loss" in the Balance Sheets. As the various settlements are made on a monthly basis, the realized gain or loss on the settlements are recorded in "Interest expense" in the Statements of Income. The realized loss on the interest rate swap agreement was $0.2 million for the three months ended May 2, 2021. The realized gain on the interest rate swap agreement was not material for the three months ended April 26, 2020.
The fair values of the Company's derivative assets and liabilities that qualify as cash flow hedges in the Balance Sheets were as follows:

|  | Balance as of
(in thousands) |  | May 2, 2021 |  | January 31, 2021
Interest rate swap agreement |  | $ | 811 |  |  | $ | 849 |
Total accrued liabilities |  | $ | 811 |  |  | $ | 849 |
Interest rate swap agreement |  | $ | 606 |  |  | $ | 933 |
Total other long-term liabilities |  | $ | 606 |  |  | $ | 933 |

During the fourth quarter of fiscal year 2021, the Company entered into an economic hedge program that uses total return swap contracts to hedge the market risk associated with the unfunded portion of the Company's deferred compensation liability. The total return swap contracts generally have a duration of one month and are rebalanced and re-hedged at the end of each monthly term. While the total returns swap contracts are treated as economic hedges, the Company has not designated them as hedges for accounting purposes. The total return swap contracts are measured at fair value and recognized in the Balance Sheets in "Accrued Liabilities" if the instruments are in a loss position and in "Other Current Assets" if the instruments are in a gain position. Unrealized gains and losses, as well as realized gains and losses for settlements, on the total return swap contracts are recognized in "Selling, general and administrative expenses" in the Statements of Income. As of May 2, 2021 and January 31, 2021, the notional values of the total return swap contracts were $14.9 million and $11.9 million, respectively, and the fair value resulted in a liability balance of $0.01 million and $0.2 million, respectively. The net gain recognized in earnings on the total return swap contracts was $1.0 million for the three months ended May 2, 2021.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following "Management’s Discussion and Analysis of Financial Condition and Results of Operations" should be read in conjunction with our interim unaudited condensed consolidated financial statements and the accompanying notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q (this "Quarterly Report"), and the "Special Note Regarding Forward-Looking and Cautionary Statements" in this Quarterly Report.
Overview
Semtech Corporation (together with its consolidated subsidiaries, the "Company", "we", "our", or "us") designs, develops, manufactures and markets high-performance analog and mixed signal semiconductors and advanced algorithms. We operate and account for results in one reportable segment through three product lines: Signal Integrity, Wireless and Sensing, and Protection.
Signal Integrity. We design, develop and market a portfolio of optical data communications and video transport products used in a wide variety of enterprise computing, communications, and industrial applications. Our comprehensive portfolio of integrated circuits ("ICs") for data centers, enterprise networks, passive optical networks ("PON"), and wireless base station optical transceivers and high-speed interfaces ranges from 100Mbps to 800Gbps and supports key industry standards such as Fibre Channel, Infiniband, Ethernet, PON and synchronous optical networks. Our video products offer advanced solutions for next generation high-definition broadcast applications, as well as highly differentiated video-over-IP technology for professional audio video ("Pro AV") applications.
Wireless and Sensing. We design, develop and market a portfolio of specialized radio frequency products used in a wide variety of industrial, medical and communications applications, and specialized sensing products used in industrial and consumer applications. Our wireless products, which include our LoRa® devices and wireless radio frequency technology ("LoRa Technology"), feature industry leading and longest range industrial, scientific and medical radio, enabling a lower total cost of ownership and increased reliability in all environments. This makes these products particularly suitable for machine to machine and Internet-of-Things ("IoT") applications. Our unique sensing technology enables proximity sensing and advanced user interface solutions for our mobile and consumer products. Our wireless and sensing products can be found in a broad range of applications in the industrial, medical, and consumer markets. We also design, develop, and market power product devices that control, alter, regulate, and condition the power within electronic systems focused on the LoRa and IoT infrastructure segment. The highest volume product types within this category are switching voltage regulators, combination switching and linear regulators, smart regulators, isolated switches, and wireless charging.
Protection. We design, develop and market high-performance protection devices, which are often referred to as transient voltage suppressors ("TVS"). TVS devices provide protection for electronic systems where voltage spikes (called transients), such as electrostatic discharge, electrical over stress or secondary lightning surge energy, can permanently damage sensitive ICs. Our portfolio of protection solutions include filter and termination devices that are integrated with the TVS device. Our products provide robust protection while preserving signal integrity in high-speed communications, networking and video interfaces. These products also operate at very low voltage. Our protection products can be found in a broad range of applications including smart phones, LCD and organic light-emitting diode TVs and displays, set-top boxes, monitors and displays, tablets, computers, notebooks, base stations, routers, automobile and industrial instruments.
Our interim unaudited condensed consolidated balance sheets are referred to herein as the "Balance Sheets" and interim unaudited condensed consolidated statements of income are referred to herein as the "Statements of Income."
Our net sales by product line were as follows:

| Three Months Ended |  |
(in thousands) | May 2, 2021 |  |  |  | April 26, 2020 |  |  |  |
Signal Integrity | $ | 66,695 |  |  |  |  | $ | 59,929 |  |  |  |  |
Wireless and Sensing | 58,507 |  |  |  |  | 32,958 |  |  |  |  |
Protection | 45,170 |  |  |  |  | 39,815 |  |  |  |  |
Total | $ | 170,372 |  |  |  |  | $ | 132,702 |  |  |  |  |

We design, develop and market a wide range of products for commercial applications, the majority of which are sold into the infrastructure, high-end consumer and industrial end markets.
Infrastructure: data centers, PON, base stations, optical networks, servers, carrier networks, switches and routers, cable modems, wireless local area network ("LAN") and other communication infrastructure equipment.
High-End Consumer: smartphones, tablets, wearables, desktops, notebooks, and other handheld products, wireless charging, set-top boxes, digital televisions, monitors and displays, digital video recorders and other consumer equipment.
26

Industrial: Internet of Things ("IoT"), analog and digital video broadcast equipment, video-over-IP solutions, automated meter reading, smart grid, wireless charging, military and aerospace, medical, security systems, automotive, industrial and home automation and other industrial equipment.
Our end customers are primarily original equipment manufacturers ("OEMs") that produce and sell electronics.
Impact of COVID-19
The COVID-19 pandemic has significantly affected health and economic conditions throughout the United States and the rest of the world including Asia, where a significant percentage of our customers, suppliers, third party foundries and subcontractors are located. As a result of the pandemic, certain of our facilities and the third-party foundries and assembly and test contractors which we outsource our manufacturing functions to, have had to periodically reduce or suspend operations. The disruption experienced during such closures has resulted in reduced production of our products, delays for delivery of our products to our customers, and reduced ability to receive supplies, which have had and may continue to have an adverse effect on our results.
Currently, customer demand remains strong and supply tight, with many of our suppliers running at or near capacity and our customers competing for the limited supply. While we have increased our inventory levels to prepare for the strong backlog of orders, we cannot assure you that we will have sufficient inventory if this high level of demand is sustained over the longer term. In addition, the prices to obtain and convert the necessary inventory have increased in certain cases, and may continue to increase. While we have been largely successful with passing on selective price increases to our customers, we cannot assure you that all future, potential price increases can be absorbed through increased pricing to our customers.
We believe we have good visibility going into the second quarter of fiscal year 2022; however, it is unknown how much of the increased demand reflects real end market strength. We believe the general supply chain constrains in the industry may be motivating certain customers to increase their orders and inventory levels to protect against the supply risk. To the extent that this is occurring, we could experience a decrease in future demand as potential excess inventory chain is worked down.
Factors Affecting Our Performance
Most of our sales to customers are made on the basis of individual customer purchase orders. Many customers include cancellation provisions in their purchase orders. Trends within the industry toward shorter lead-times and "just-in-time" deliveries have resulted in our reduced ability to predict future shipments. As a result, we rely on orders received and shipped within the same quarter for a significant portion of our sales. Orders received and shipped in the first quarters of fiscal years 2022 and 2021 represented 18% and 34% of net sales, respectively. Sales made directly to customers during the first quarters of fiscal years 2022 and 2021 were 14% and 22% of net sales, respectively. The remaining sales were made through independent distributors. The decline in direct sales is due to customers electing to leverage the value of distribution to better manage their supply chain.
Our business relies on foreign-based entities. Many of our third-party subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in foreign countries including Taiwan and China. Foreign sales constituted approximately 89% and 91% of our net sales during the first quarters of fiscal years 2022 and 2021. Approximately 78% and 80% of sales during the first quarters of fiscal years 2022 and 2021, respectively, were to customers located in the Asia-Pacific region. The remaining foreign sales were primarily to customers in Europe, Canada, and Mexico. Doing business in foreign locations also subjects us to export restrictions and trade laws, which may limit our ability to sell to certain customers. For example, the U.S. Department of Commerce expanded its restrictions on certain technology sold to or for Huawei in 2020, which adversely impacted our sales to this customer.
We use several metrics as indicators of future potential growth. The indicators that we believe best correlate to potential future sales growth are design wins and new product releases. There are many factors that may cause a design win or new product release not to result in sales, including a customer's decision not to go to system production, a change in a customer’s perspective regarding a product’s value or a customer’s product failing in the end market. As a result, although a design win or new product introduction is an important step towards generating future sales, it does not inevitably result in us being awarded business or receiving a purchase commitment.

Comparison of the Three Months Ended May 2, 2021 and April 26, 2020
The following table summarizes our net sales by major end market:

| Three Months Ended
(in thousands, except percentages) | May 2, 2021 |  | April 26, 2020
Infrastructure | $ | 61,350 |  |  | 36 | % |  | $ | 58,038 |  |  | 43 | %
High-End Consumer | 53,816 |  |  | 32 | % |  | 35,480 |  |  | 27 | %
Industrial | 55,206 |  |  | 32 | % |  | 39,184 |  |  | 30 | %
Total | $ | 170,372 |  |  | 100 | % |  | $ | 132,702 |  |  | 100 | %

Net Sales
Net sales for the first three months of fiscal year 2022 were $170.4 million, an increase of 28.4% compared to $132.7 million for the first three months of fiscal year 2021. During the first three months of fiscal year 2022, we experienced strong demand across all three of our end markets compared to the prior year when our revenue was adversely impacted by a delay in certain shipments of our products due to COVID-19 related shutdowns of our plant in Reynosa, Mexico, as well as certain
28

subcontractors in Malaysia. Our industrial end market increased $16.0 million versus the prior year primarily due to an approximately $12 million increase in LoRa-enabled product sales, as we gained traction in the ever expanding range of Internet-of-Things applications. In our high-end consumer end market, net sales increased by $18.3 million primarily driven by an approximately $13 million increase in our proximity sensing products. Our infrastructure end market revenue increased by $3.3 million driven by strong 10G PON sales, partially offset by slightly lower data center demand by cloud and hyperscale providers.
Based on record bookings and backlog entering the quarter, we estimate net sales for the second quarter of fiscal year 2022 to be between $177.0 million and $187.0 million. The range of guidance reflects continued uncertainty regarding macro-related events and those associated with the COVID-19 pandemic discussed above.
Gross Profit
For the first three months of fiscal year 2022, gross profit increased to $104.9 million from $80.8 million for the first three months of fiscal year 2021 as a result of higher sales. Gross margins were 61.5% for the first three months of fiscal year 2022 compared to 60.9% for the first three months of fiscal year 2021, reflecting a more favorable product mix. For the second quarter of fiscal year 2022, we expect our gross margins to be in the range of 61.3% to 62.3%.
Operating Costs and Expenses

| Three Months Ended |  | Change
(in thousands, except percentages) | May 2, 2021 |  | April 26, 2020 |
Selling, general and administrative | $ | 38,804 |  |  | 50 | % |  | $ | 34,600 |  |  | 54 | % |  | 12 | %
Product development and engineering | 36,790 |  |  | 48 | % |  | 27,586 |  |  | 42 | % |  | 33 | %
Intangible amortization | 1,298 |  |  | 2 | % |  | 2,840 |  |  | 4 | % |  | (54) | %
Changes in the fair value of contingent earn-out obligations | — |  |  | — | % |  | (33) |  |  | — | % |  | 100 | %
Total operating costs and expenses | $ | 76,892 |  |  | 100 | % |  | $ | 64,993 |  |  | 100 | % |  | 18 | %

Selling, General and Administrative Expenses
Selling, general and administrative ("SG&A") expenses increased $4.2 million for the first three months of fiscal year 2022 compared to the first three months of fiscal year 2021 primarily as a result of a $4.3 million increase in staffing-related costs, including higher costs related to deferred compensation and share based compensation.
Product Development and Engineering Expenses
Product development and engineering expenses increased $9.2 million in the first three months of fiscal year 2022 compared to the first three months of fiscal year 2021 as a result of fluctuations in the timing of development activities and a $2.4 million increase in staffing-related costs primarily related to higher headcount. The levels of product development and engineering expenses reported in a fiscal period can be significantly impacted, and therefore experience period-over-period volatility, by the number of new product tape-outs and by the timing of recoveries from non-recurring engineering services, which are typically recorded as a reduction to product development and engineering expense.
Intangible Amortization
Intangible amortization was $1.3 million and $2.8 million for the first three months of fiscal years 2022 and 2021, respectively. This decrease was primarily due to certain finite-lived intangible assets associated with the acquisition of Gennum Corporation that had become fully amortized during fiscal year 2021.
Changes in the Fair Value of Contingent Earn-out Obligations
The change in the fair value of contingent earn-out obligations for the first three months of fiscal year 2021 reflects the difference between the final earn-out targets achieved for Cycleo SAS in fiscal year 2021 and the forecast achievement level at the end of fiscal year 2020.
Interest Expense
Interest expense, including amortization of debt discounts and issuance costs, was $1.2 million and $1.6 million for the first three months of fiscal years 2022 and 2021, respectively. This decrease was primarily due to lower interest rates and lower overall debt levels.
Investment Impairments and Credit Loss Reserves
During the first three months of fiscal year 2022, investment impairments and credit loss reserves totaled a loss of $0.2 million due to adjustments to our reserve for current expected credit losses. During the first three months of fiscal year 2021, investment impairments and credit loss reserves totaled a loss of $3.6 million including other-than-temporary impairments of
29

two cost method investments totaling $1.2 million, as well as $2.4 million of adjustments to our reserve for current expected credit losses, which were, in part, due to the impact of the COVID-19 pandemic on early-stage development companies.
Provision for Income Taxes
The effective tax rates for the first three months of fiscal years 2022 and 2021 were a provision rate of 12.0% and a provision rate of 12.4%, respectively. In the first three months of fiscal year 2022, we recorded income tax expense of $3.2 million, compared to income tax expense of $1.4 million in the first three months of fiscal year 2021. The effective tax rate in the first three months of fiscal year 2022 was lower than the effective tax rate in the first three months of fiscal year 2021 primarily due to the impact of regional mix of income. The effective tax rate in the first three months of fiscal years 2022 and 2021 differs from the statutory federal income tax rate of 21% primarily due to regional mix of income, excess tax benefits from share-based compensation and research and development tax credits.
As a global organization, we are subject to audit by taxing authorities in various jurisdictions. To the extent that an audit, or the closure of a statute of limitations, results in adjusting our reserves for uncertain tax positions, our effective tax rate could experience extreme volatility since any adjustment would be recorded as a discrete item in the period of adjustment.
Liquidity and Capital Resources
Our capital requirements depend on a variety of factors including, but not limited to, the rate of increase or decrease in our existing business base; the success, timing and amount of investment required to bring new products to market; sales growth or decline; potential acquisitions; the general economic environment in which we operate; and our ability to generate cash flow from operations, which are more uncertain as a result of the COVID-19 pandemic and its impact on the general economy. Our liquidity needs during this uncertain time will depend on multiple factors, including our ability to continue operations and production of our products, the COVID-19 pandemic's effects on our customers, the availability of sufficient amounts of financing and our operating performance.
We believe that our cash on hand, cash available from future operations and available borrowing capacity under our Credit Facility are sufficient to meet liquidity requirements for at least the next 12 months, including funds needed for our material cash requirements. As of May 2, 2021, we had $258.2 million in cash and cash equivalents and $423.0 million of undrawn capacity on our Credit Facility (as defined below). Over the longer-term, we believe our strong cash-generating business model will continue to provide adequate liquidity to fund our normal operations, which have minimal capital intensity. To the extent that we enter into acquisitions or strategic partnerships, we may be required to raise additional capital through debt issuances or equity offerings. In addition, we expect to refinance our Credit Facility ahead of its maturity in November 2024. While we have not had issues securing favorable financing historically, there is no assurance that we will be able to refinance or secure additional capital at favorable terms, or at all in the future.
A meaningful portion of our capital resources, and the liquidity they represent, are held by our foreign subsidiaries. As of May 2, 2021, our foreign subsidiaries held approximately $206.8 million of cash and cash equivalents, compared to $182.9 million at January 31, 2021.
We expect our future cash uses will be for capital expenditures, repurchases of our common stock and potentially, acquisitions and other investments that support achievement of our business strategies. We expect to fund those cash requirements through our cash from operations and borrowings against our Credit Facility.
Credit Facility
On November 7, 2019, we, with certain of our domestic subsidiaries as guarantors, entered into an amended and restated credit agreement (the "Credit Agreement") with the lenders party thereto and HSBC Bank USA, National Association, as administrative agent, swing line lender and letter of credit issuer in order to provide a more flexible borrowing structure by expanding the borrowing capacity of the revolving loans under the senior secured first lien credit facility (the "Credit Facility") to $600.0 million, eliminating the term loans under the prior facility and extending the maturity to November 7, 2024.
In the first three months of fiscal years 2022 and 2021, we made payments on our Credit Facility that totaled $4.0 million and $4.0 million, respectively. As of May 2, 2021, we had $177.0 million of outstanding borrowings on our Credit Facility, which had $423.0 million of undrawn capacity.
The Credit Agreement provides that, subject to certain customary conditions, including obtaining commitments with respect thereto, we may request the establishment of one or more term loan facilities and/or increases to the revolving loans in a principal amount not to exceed (a) $300.0 million, plus (b) an unlimited amount, so long as our consolidated leverage ratio, determined on a pro forma basis, does not exceed 3.00 to 1.00. However, the lenders are not required to provide such increase upon our request.
Interest on loans made under the Credit Facility in U.S. Dollars accrues, at our option, at a rate per annum equal to (1) the Base Rate (as defined below) plus a margin ranging from 0.25% to 1.25% depending upon our consolidated leverage ratio or (2) LIBOR (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by us plus a margin ranging
30

from 1.25% to 2.25% depending upon our consolidated leverage ratio (such margin, the "Applicable Margin"). The "Base Rate" is equal to a fluctuating rate equal to the highest of (a) the prime rate of the Administrative Agent, (b) 0.50% above the federal funds effective rate published by the Federal Reserve Bank of New York and (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars), plus 1.00%.
In the first quarter of fiscal year 2021, we entered into an interest rate swap agreement with a three-year term to hedge the variability of interest payments on the first $150.0 million of debt outstanding under our Credit Facility. Based on our current leverage ratio as of May 2, 2021, interest payments on $150.0 million of our debt are fixed at 1.9775%.
All obligations of the Company under the Credit Agreement are unconditionally guaranteed by all of our direct and indirect domestic subsidiaries, other than certain excluded subsidiaries, including, but not limited to, any domestic subsidiary the primary assets of which consist of equity or debt of non-U.S. subsidiaries, certain immaterial non-wholly-owned domestic subsidiaries and subsidiaries that are prohibited from providing a guarantee under applicable law or that would require governmental approval to provide such guarantee. The Company and the guarantors have also pledged substantially all of their assets to secure their obligations under the Credit Agreement.
No amortization is required with respect to the revolving loans and we may voluntarily prepay borrowings at any time and from time to time, without premium or penalty, other than customary "breakage costs" and fees for LIBOR-based loans.
The Credit Agreement contains customary covenants, including limitations on our ability to, among other things, incur indebtedness, create liens on assets, engage in certain fundamental corporate changes, make investments, repurchase stock, pay dividends or make similar distributions, engage in certain affiliate transactions, or enter into agreements that restrict our ability to create liens, pay dividends or make loan repayments. In addition, we must comply with financial covenants, including maintaining a maximum consolidated leverage ratio, determined as of the last day of each fiscal quarter, of 3.50 to 1.00 or less, provided that, such maximum consolidated leverage ratio may be increased to 4.00 to 1.00 for the four consecutive fiscal quarters ending on or after the date of consummation of a permitted acquisition that constitutes a "Material Acquisition" under the Credit Agreement, subject to the satisfaction of certain conditions. As of May 2, 2021, we were in compliance with the covenants in our Credit Agreement.
The Credit Agreement also contains customary provisions pertaining to events of default. If any event of default occurs, the obligations under the Credit Agreement may be declared due and payable, terminated upon written notice to us and existing letters of credit may be required to be cash collateralized.
Capital Expenditures and Research and Development
We incur significant expenditures in order to fund the development, design and manufacture of new products. We intend to continue to focus on those areas that have shown potential for viable and profitable market opportunities, which may require additional investment in equipment and the hiring of additional design and application engineers aimed at developing new products. Certain of these expenditures, particularly the addition of design engineers, do not generate significant payback in the short-term. We plan to finance these expenditures with cash generated by our operations and our existing cash balances.
Purchases under our Stock Repurchase Program
We currently have in effect a stock repurchase program that was initially approved by our Board of Directors in March 2008. On March 11, 2021, the Company's Board of Directors approved the expansion of the stock repurchase program by $350.0 million. This program represents one of our principal efforts to return value to our stockholders. We repurchased 360,942 shares under this program in the first three months of fiscal year 2022 for $25.0 million. In the first three months of fiscal year 2021, we repurchased 855,042 shares under this program for $30.0 million. As of May 2, 2021, the remaining authorization under this program was $364.2 million.
Working Capital
Working capital, defined as total current assets less total current liabilities, fluctuates depending on end-market demand and our effective management of certain items such as receivables, inventory and payables. In times of escalating demand, our working capital requirements may increase as we purchase additional manufacturing materials and increase production. In addition, our working capital may be affected by potential acquisitions and transactions involving our debt instruments. Although investments made to fund working capital will reduce our cash balances, these investments are necessary to support business and operating initiatives. Our working capital, excluding cash and cash equivalents, was $106.6 million and $96.3 million as of May 2, 2021 and January 31, 2021, respectively. Our working capital, including cash and cash equivalents, was $364.9 million and $365.2 million as of May 2, 2021 and January 31, 2021, respectively.
Cash Flows
One of our primary goals is to continually improve the cash flows from our existing operating activities. Additionally, we will continue to seek to maintain and improve our existing business performance with capital expenditures and, potentially,
31

acquisitions and other investments that support achievement of our business strategies. Acquisitions may be made for either cash or stock consideration, or a combination of both.
In summary, our cash flows for each period were as follows:

| Three Months Ended
(in thousands) | May 2, 2021 |  | April 26, 2020
Net cash provided by operating activities | $ | 32,585 |  |  | $ | 26,083 |
Net cash used in investing activities | (8,655) |  |  | (11,560) |
Net cash used in financing activities | (34,602) |  |  | (38,900) |
Net decrease in cash and cash equivalents | $ | (10,672) |  |  | $ | (24,377) |

Operating Activities
Net cash provided by operating activities is driven by net income adjusted for non-cash items and fluctuations in operating assets and liabilities.
Operating cash flows for the first three months of fiscal year 2022 compared to the first three months of fiscal year 2021 were favorably impacted by a 28.4% increase in net sales, partially offset by a rise in SG&A expenses related to higher staffing-related costs and by an increase in product development and engineering expenses related to higher staffing-related costs and fluctuations in the timing of development activities.
Investing Activities
Net cash used in investing activities was primarily attributable to capital expenditures and purchases of investments, net of proceeds from sales of property, plant and equipment and proceeds from sales of investments.
Capital expenditures were $5.8 million for the first three months of fiscal year 2022, compared to $7.7 million for the first three months of fiscal year 2021. In the first three months of fiscal years 2022 and 2021, we made significant investments to update and expand our production capabilities.
In the first three months of fiscal year 2022, we paid $2.9 million for strategic investments, including investments in companies that are enabling the LoRa and LoRaWAN®-based ecosystem, compared to $3.9 million of investments in the first three months of fiscal year 2021.
Financing Activities
Net cash used in financing activities is primarily attributable to repurchases of outstanding common stock, payments related to employee share-based compensation payroll taxes and principal payments related to our long-term debt, offset by proceeds from stock option exercises.
In the first three months of fiscal year 2022, we paid $6.2 million for employee share-based compensation payroll taxes and received $0.6 million in proceeds from the exercise of stock options, compared to payments of $5.8 million for employee share-based compensation payroll taxes and proceeds of $0.9 million from the exercise of stock options in the first three months of fiscal year 2021. We do not directly control the timing of the exercise of stock options. Such exercises are independent decisions made by grantees and are influenced most directly by the stock price and the expiration dates of stock option awards. Such proceeds are difficult to forecast, resulting from several factors that are outside our control. We believe that such proceeds will remain a nominal source of cash in the future.
Critical Accounting Estimates
Our critical accounting estimates are disclosed in "Management’s Discussion and Analysis of Financial Condition and Results of Operations" included in Item 7 of our Annual Report on Form 10-K. There have been no significant changes to our policies during the three months ended May 2, 2021. For a discussion of recent accounting pronouncements, see Note 1 to our interim unaudited condensed consolidated financial statements.
Available Information
General information about us can be found on our website at www.semtech.com. The information on our website is for informational purposes only and should not be relied on for investment purposes. The information on our website is not incorporated by reference into this Quarterly Report and should not be considered part of this or any other report filed with the SEC.
We make available free of charge, either by direct access on our website or by a link to the SEC website, our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or as soon as
32

reasonably practicable after such reports are electronically filed with, or furnished to, the SEC. Our reports filed with, or furnished to, the SEC are also available directly at the SEC’s website at www.sec.gov.
ITEM 3.Quantitative and Qualitative Disclosures About Market Risk
We are subject to a variety of market risks, including commodity risk and the risks related to foreign currency, interest rates and market performance that are discussed in Item 7A of our Annual Report. Many of the factors that can have an impact on our market risk are external to us, and so we are unable to fully predict them.
We considered the historical trends in foreign currency exchange rates and determined that it is reasonably possible that adverse changes in foreign exchange rates of 10% for all currencies could be experienced in the near-term. These reasonably possible adverse changes were applied to our total monetary assets and liabilities denominated in currencies other than our functional currency as of the first quarter of fiscal year 2022. The adverse impact these changes would have had (after taking into account balance sheet hedges only) would not have had a material impact on our income before taxes.
We are subject to interest rate risk in connection with the portion of the outstanding debt under our Credit Facility that bears interest at a variable rate as of May 2, 2021. As of May 2, 2021, we had $177.0 million of outstanding borrowings on our Credit Facility, which had $423.0 million of undrawn capacity.
During fiscal year 2021, we entered into an interest rate swap agreement with a three-year term to hedge the variability of interest payments on the first $150.0 million of debt outstanding under our Credit Facility. Based on our current leverage ratio as of May 2, 2021, interest payments on $150.0 million of our debt are fixed at 1.9775%. Borrowings under our Credit Facility in excess of $150.0 million bear interest at a rate per annum equal to (1) the Base Rate plus a margin ranging from 0.25% to 1.25% depending upon our consolidated leverage ratio or (2) LIBOR (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by us plus a margin ranging from 1.25% to 2.25% depending upon our consolidated leverage ratio (such margin, the "Applicable Margin"). The Base Rate is equal to a fluctuating rate equal to the highest of (a) the prime rate of the Administrative Agent, (b) 0.50% above the federal funds effective rate published by the Federal Reserve Bank of New York and (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars), plus 1.00%. Interest on loans made under the Credit Facility in Alternative Currencies accrues at a rate per annum equal to LIBOR (determined with respect to deposits in the applicable Alternative Currency) (other than loans made in Canadian Dollars, for which a special reference rate for Canadian Dollars applies) for an interest period to be selected by us plus the Applicable Margin. Based upon the amount of our outstanding indebtedness as of May 2, 2021, a one percentage point increase in LIBOR would not have a material impact on our interest expense as only $27.0 million of our outstanding debt balance remains subject to a floating rate.
The Chief Executive of the U.K. Financial Conduct Authority (the “FCA”), which regulates LIBOR, has announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. For U.S dollar LIBOR, publication of the one-week and two-month LIBOR settings will cease after December 31, 2021, and publication of the overnight and 12-month LIBOR settings will cease after June 30, 2023. Immediately after June 30, 2023, the one-month, three-month and six-month U.S. dollar LIBOR settings will no longer be representative. Given these changes, the LIBOR administrator has advised that no new contracts using U.S. dollar LIBOR should be entered into after December 31, 2021. It is also possible that U.S. LIBOR will be discontinued or modified prior to June 30, 2023.
Our Credit Facility provides that, if it is publicly announced that the administrator of LIBOR has ceased or will cease to provide LIBOR, if it is publicly announced by the applicable regulatory supervisor that LIBOR is no longer representative, or if either the administrative agent or lenders holding 50% of the aggregate principal amount of our revolving commitments and term loans elect, we and the administrative agent may amend our Credit Agreement to replace LIBOR with an alternate benchmark rate. This alternative benchmark rate may include a forward-looking term rate that is based on the secured overnight financing rate, also known as SOFR, published by the Federal Reserve Bank of New York.
Interest rates also affect our return on excess cash and investments. As of May 2, 2021, we had $258.2 million of cash and cash equivalents. A majority of our cash and cash equivalents generate interest income based on prevailing interest rates. Interest income, net of reserves, generated by our investments and cash and cash equivalents was not material in the first quarter of fiscal year 2022. A significant change in interest rates would impact the amount of interest income generated from our cash and investments. It would also impact the market value of our investments.
Our investments are primarily subject to credit risk. Our investment guidelines prescribe credit quality, permissible investments, diversification, and duration restrictions. These restrictions are intended to limit risk by restricting our investments to high quality debt instruments with relatively short-term durations. Our investment strategy limits investment of new funds and maturing securities to U.S. Treasury, Federal agency securities, high quality money market funds and time deposits with our principal commercial banks. Outside of these investment guidelines, we also invest in a limited amount of debt securities in privately held companies that we view as strategic to our business. For example, many of these investments are in companies that are enabling the LoRa and LoRaWAN®-based ecosystem. We evaluate the credit risk of these investments on a quarterly basis and increased our current credit loss and reserves by $0.2 million in the first quarter of fiscal year 2022, related to the
33

credit risk on our debt securities investments, resulting in a current expected credit loss reserve balance on our available-for-sale and held-to-maturity debt securities of $3.6 million as of May 2, 2021.
ITEM 4.Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), which are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our CEO and CFO, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on that evaluation, our CEO and CFO concluded that, our disclosure controls and procedures were effective as of May 2, 2021.
Changes in Internal Controls
As of May 2, 2021, there were no changes to our internal control over financial reporting that occurred during the fiscal quarter then ended that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
