Current report

Other income, net, was $33.6 million for the year ended December 31, 2024, compared with $24.1 million for the year ended December 31, 2023. The increase was primarily due to an increase in amortization of discounts on available-for-sale securities, partially offset by an increase in charitable contributions.

Current report

The net income tax benefit for the year ended December 31, 2024 was $1.2 billion, or 211.9% of pre-tax income. The effective tax rate was lower than the federal statutory rate of 21% primarily due to tax benefits associated with a ten-year tax incentive. In 2024, one of our foreign subsidiaries was granted a ten-year tax incentive, beginning in 2025. A deferred tax benefit of approximately $1.3 billion, net of $0.1 billion of valuation allowance, was recorded during the year ended December 31, 2024 to reflect the estimated future reductions in cash tax paid in that jurisdiction associated with the incentive. Furthermore, the 2024 effective tax rate benefited from lower statutory tax rates at certain of our foreign subsidiaries. The effective tax rate was partially offset by the inclusion of the global intangible low-taxed income (“GILTI”) tax, the addition of a valuation allowance against foreign tax assets, and excess tax benefits from stock-based compensation.

Current report

In December 2024, we completed an intercompany transaction that resulted in one of our foreign subsidiaries recording a step up in the tax basis of intangible assets of approximately $23.2 billion. This resulted in a deferred tax difference between the U.S. GAAP basis and local tax basis of the specified intangibles. We do not expect to realize the deferred tax asset for U.S. GAAP purposes; therefore, we have recorded a full valuation allowance as of December 31, 2024.

Current report

In January 2025, the OECD released new Administrative Guidance on the application of the Global Anti-Base Erosion Model Rules. We will continue to evaluate the impact of this release or of other prospective guidance on our future global tax provision.

Current report

For the year ended December 31, 2024, the $401.8 million increase in cash provided by investing activities compared to the prior period was primarily due to a $1.0 billion year-over-year increase in the sale of investments, partially offset by a $500.8 million increase in the purchase of investments, an increase of $88.5 million in property and equipment purchases and a $33.3 million acquisition in the year ended December 31, 2024.

Current report

In February 2025*,* our Board of Directors approved a new stock repurchase program authorizing the Company to repurchase up to $500.0 million of our common stock through February 2028*.* Shares are retired upon repurchase. The repurchases, if any, will be funded from available working capital and cash repatriation from our subsidiaries.

Previous report

We account for price adjustments and stock rotation rights as variable consideration that reduces the transaction price and recognize that reduction in the same period the associated revenue is recognized. Certain U.S.-based distributors have price adjustment rights when they sell our products to their end customers at a price that is lower than the distribution price invoiced by us. When we receive claims from the distributors that products have been sold to the end customers at the lower price, we issue the distributors credit memos for the price adjustments. We estimate the price adjustments using the expected value method based on an analysis of historical claims, at both the distributor and product level, as well as an assessment of any known trends of product sales mix.

Previous report

Certain distributors have limited stock rotation rights that permit the return of a small percentage of the previous six months’ purchases in accordance with the contract terms. We estimate the stock rotation returns using the expected value method based on an analysis of historical returns, and the current level of inventory in the distribution channel.

Previous report

Overall, our estimates of adjustments to contract price due to variable consideration have been materially consistent with actual results; however, these estimates are subject to management’s judgment and actual provisions could be different from our estimates and current provisions, resulting in future adjustments to our revenue and operating results.

Previous report

We record a contingent liability related to pending legal and regulatory proceedings when it is probable that a loss has been incurred and the amount is reasonably estimable. Based on the facts and circumstances in each matter, the determination of such liability requires significant judgment. In determining the amount of a contingent loss, we take into account advice received from experts for each specific matter regarding the status of legal proceedings, settlement negotiations, prior case history and other factors. Should the judgments and estimates made by management need to be adjusted as additional information becomes available, we may need to record additional contingent losses that could materially and adversely impact our results of operations. Alternatively, if the judgments and estimates made by management are adjusted, for example, if a particular contingent loss does not occur, the contingent loss recorded would be reversed which could result in a favorable impact on our results of operations.

Previous report

Other income, net, was $24.1 million for the year ended December 31, 2023, compared with other expense, net, of $1.8 million for the year ended December 31, 2022. The increase in other income was primarily due to an increase of $18.6 million in net interest income as a result of higher interest rates, and an increase of $15.1 million in income related to changes in the value of deferred compensation plan investments, partially offset by an increase of $9.0 million in charitable contributions.

Previous report

In August 2022, the CHIPS Act and the Inflation Reduction Act of 2022 (the “IRA”) were enacted and signed into law, which did not have a material impact on our income tax provisions, results of operations or financial condition for the years ended December 31, 2023 or 2022. We will continue to monitor any new developments related to the CHIPS Act and the IRA and evaluate their impact on our financial statements.

Previous report

For the year ended December 31, 2023, the $166.2 million increase in cash used in investing activities compared to the prior period was primarily due to an increase of $518.9 million in purchases of investments, partially offset by an increase of $340.4 million in sales of investments.

Previous report

On January 3, 2024, we acquired Axign, a Dutch company for $33.8 million in cash. See Note 17 of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for additional information.

Previous wording

We operate in the cyclical semiconductor industry. We are subject to industry downturns, but we have targeted product and market areas that we believe have the ability to offer above average industry performance over the long term. Historically, our revenue has generally been higher in the second half of the year than in the first half although various factors, such as market conditions and the timing of key product introductions, could impact this trend.

Previous wording

Following the introduction of a product, our sales cycle generally takes a number of quarters after we receive an initial customer order for a new product to ramp up. Typical supply chain lead times for orders are generally 16 to 26 weeks. These factors, combined with the fact that our customers can cancel or reschedule orders without significant penalty to the customer, make the forecasting of our orders and revenue difficult.

Previous wording

We derive most of our revenue from sales through distribution arrangements and direct sales to customers in Asia, where our products are incorporated into end-user products. Our revenue from direct or indirect sales to customers in Asia was 87%, 86% and 90% for the years ended December 31, 2023, 2022 and 2021, respectively. We derive a majority of our revenue from the sales of our DC to DC converter products which serve the storage and computing, enterprise data, automotive, industrial, communications and consumer markets. We believe our ability to achieve revenue growth will depend, in part, on our ability to develop new products, enter new market segments, gain market share, manage litigation risk, diversify our customer base and continue to secure manufacturing capacity.

Previous wording

During 2023, the semiconductor industry faced, and continues to face, a number of macro-economic challenges including reduced consumer spending, fluctuations in demand for semiconductors, rising inflation, increased interest rates, and fluctuations in currency rates. We remain cautious in light of continued challenging macroeconomic conditions and will continue to monitor the potential impact on our operations. The extent and duration of the direct and indirect impact of macroeconomic events on our business, results of operations and overall financial position remain uncertain and depend on future developments.

Current wording

The semiconductor industry has historically been impacted by various macro-economic challenges including fluctuations in consumer spending, fluctuations in demand for semiconductors, rising inflation, increased interest rates, and fluctuations in currency rates. We remain cautious in light of continued challenging macroeconomic conditions and will continue to monitor the potential impact on our operations. The extent and duration of the direct and indirect impact of macroeconomic events on our business, results of operations and overall financial position remain uncertain and depend on future developments.

Previous wording

We closely monitor changes to export control laws, trade regulations and other trade requirements. As of December 31, 2023 and through the date we filed this Annual Report, no existing or newly introduced restrictions have had a material impact on our revenue and operations. We will continue to monitor any changes or developments to export control laws, trade regulations and other trade requirements, or interpretations thereof and are committed to complying with all applicable trade laws, regulations and other requirements.

Current wording

We closely monitor changes to export control laws, tariffs, trade regulations and other trade requirements. As of December 31, 2024 and through the date we filed this Annual Report, no restrictions or requirements have had a material impact on our revenue and operations; however, such restrictions can be enacted quickly and unexpectedly and could impact our business in the future. We will continue to monitor any changes or developments to export control laws, trade regulations and other trade requirements, or interpretations thereof and are committed to complying with all applicable trade laws, regulations and other requirements.

Previous wording

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an on-going basis, including those related to revenue recognition, stock-based compensation, inventories, income taxes and contingencies. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Estimates and judgments used in the preparation of our financial statements are, by their nature, uncertain and unpredictable, and depend upon, among other things, many factors outside of our control, including demand for our products, economic conditions and other current and future events, such as macroeconomic factors, including the impact of the 2023 banking crisis, global economic downturn, Russia-Ukraine conflict and the Middle East conflict. Actual results could differ from these estimates and assumptions, and any such differences may be material to our consolidated financial statements. See Note 1 of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for a summary of significant accounting policies and the effect on our financial statements.

We believe the following critical accounting policies reflect our more significant judgments used in the preparation of our consolidated financial statements.

Current wording

We believe the following critical accounting estimates reflect our significant judgments used in the preparation of our consolidated financial statements.

Previous wording

As of December 31, 2023 and 2022, we had a valuation allowance of $35.0 million and $20.3 million, respectively, attributable to management’s determination that it is more likely than not that certain deferred tax assets will not be fully realized. In the event we determine that it is more likely than not that we would be able to realize the deferred tax assets in the future in excess of our net recorded amount, an adjustment to the valuation allowance for the deferred tax assets would increase income in the period such determination was made. Likewise, should it be determined that additional amounts of the net deferred tax assets will not be realized in the future, an adjustment to increase the deferred tax assets valuation allowance will be charged to income in the period such determination is made.

Current wording

As of December 31, 2024 and 2023, we had a valuation allowance of $3.6 billion and $35.0 million, respectively, attributable to management’s determination that it is more likely than not that certain deferred tax assets will not be fully realized. In 2024, one of the Company’s foreign subsidiaries was granted a ten-year tax incentive, beginning in tax year 2025. In the event we determine that it is more likely than not that we would be able to realize the deferred tax assets in the future in excess of our net recorded amount, an adjustment to the valuation allowance for the deferred tax assets would increase income in the period such determination is made. Likewise, should it be determined that additional amounts of the net deferred tax assets will not be realized in the future, an adjustment to increase the deferred tax assets valuation allowance will be charged to income in the period such determination is made. For example, a change in forecasted income could impact the expected utilization of our tax incentive and result in an income tax benefit or additional income tax expense in our financial statements in the period such determination is made.

Previous wording

Revenue for the year ended December 31, 2023 was $1,821.1 million, an increase of $27.0 million, or 1.5%, from $1,794.1 million for the year ended December 31, 2022. The increase in revenue was primarily due to increases in the average selling prices resulting primarily from product mix, partially offset by lower shipment volume.

Current wording

Revenue for the year ended December 31, 2024 was $2.2 billion, an increase of $386.0 million, or 21.2%, from $1.8 billion for the year ended December 31, 2023. The increase in revenue was primarily due to increases in shipment volume and average selling prices resulting primarily from product mix.

Previous wording

For the year ended December 31, 2023, revenue from the storage and computing market increased $38.5 million, or 8.5%, from the same period in 2022. This increase was primarily driven by increased sales of products for notebooks. Revenue from the enterprise data market increased $71.6 million, or 28.5%, from the same period in 2022. This increase was primarily due to higher sales of our power management solutions for AI applications. Revenue from the automotive market increased $94.6 million, or 31.5%, from the same period in 2022. This increase was primarily driven by increased sales of our highly integrated applications supporting advanced driver assistance systems, body electronics and the digital cockpit. Revenue from the industrial market decreased $46.5 million, or 21.2%, from the same period in 2022. This decrease primarily reflected lower sales in applications for industrial automation, security and power sources. Revenue from the communications market decreased $46.5 million, or 18.5%, from the same period in 2022. The decrease was a result of lower 4G and 5G infrastructure sales. Revenue from the consumer market decreased $84.8 million, or 26.6%, from the same period in 2022. This decrease was a result of broad market weakness across all segments.

Current wording

For the year ended December 31, 2024, revenue from the enterprise data market increased $393.3 million, or 121.8%, from the same period in 2023. This increase was primarily due to higher sales of our power management solutions for AI applications. Revenue from the communications market increased $21.0 million, or 10.2%, from the same period in 2023. The increase was a result of higher sales of power solutions for optical modules and routers, partially offset by lower sales of networking solutions. Revenue from the automotive market increased $19.3 million, or 4.9%, from the same period in 2023. This increase was primarily driven by increased sales of our highly integrated applications supporting advanced driver assistance systems, partially offset by lower sales of applications supporting body electronics and infotainment. Revenue from the storage and computing market increased $10.4 million, or 2.1%, from the same period in 2023. This increase was primarily driven by increased sales of products for notebooks. Revenue from the consumer market decreased $32.6 million, or 13.9%, from the same period in 2023. This decrease was a result of broad market weakness. Revenue from the industrial market decreased $25.4 million, or 14.7%, from the same period in 2023. This decrease primarily reflected lower sales of products related to industrial meter and security applications.

Previous wording

Cost of revenue was $800.0 million, or 43.9% of revenue, for the year ended December 31, 2023, and $745.6 million, or 41.6% of revenue, for the year ended December 31, 2022. The $54.4 million increase in cost of revenue was primarily driven by product mix, partially offset by lower inventory write-downs and warranty expenses.

Current wording

Cost of revenue was $986.2 million, or 44.7% of revenue, for the year ended December 31, 2024, and $800.0 million, or 43.9% of revenue, for the year ended December 31, 2023. The $186.2 million increase in cost of revenue was primarily driven by increases in shipment volume and the average costs due to product mix.

Previous wording

Gross margin was 56.1% for the year ended December 31, 2023, compared with 58.4% for the year ended December 31, 2022. The decrease in gross margin was mainly driven by product mix, partially offset by lower inventory write-downs and warranty expenses as a percentage of revenue.

Current wording

Gross margin was 55.3% for the year ended December 31, 2024, compared with 56.1% for the year ended December 31, 2023. The decrease in gross margin was mainly driven by higher inventory write-downs as a percentage of revenue.

Previous wording

R&D expenses were $263.6 million, or 14.5% of revenue, for the year ended December 31, 2023, and $240.2 million, or 13.4% of revenue, for the year ended December 31, 2022. The $23.5 million increase in R&D expenses was primarily due to a $20.9 million increase in new product development expenses, a $5.6 million increase in expenses related to changes in the value of deferred compensation plan liabilities and a $1.8 million increase in depreciation. This increase was partially offset by an $8.1 million decrease in cash compensation expenses, which was driven by decreased bonuses.

Current wording

R&D expenses were $324.7 million, or 14.7% of revenue, for the year ended December 31, 2024, and $263.6 million, or 14.5% of revenue, for the year ended December 31, 2023. The $61.1 million increase in R&D expenses was primarily due to a $27.7 million increase in cash compensation expenses and benefits, an $11.0 million increase in stock-based compensation expenses and related payroll taxes, a $7.6 million increase in new product development expenses and a $5.0 million increase consisting mostly of software licensing fees.

Previous wording

SG&A expenses primarily include cash compensation and benefits, stock-based compensation and deferred compensation for sales, marketing and administrative personnel, sales commissions, travel expenses, facilities costs, third party service fees and litigation expenses.

Current wording

SG&A expenses primarily include cash compensation and benefits, stock-based compensation and deferred compensation for sales, marketing and administrative personnel, sales commissions, travel expenses, facilities costs, third party service fees and legal expenses.

Previous wording

SG&A expenses were $275.7 million, or 15.1% of revenue, for the year ended December 31, 2023, and $281.6 million, or 15.6% of revenue, for the year ended December 31, 2022. The $5.9 million decrease in SG&A expenses was driven by a $12.4 million decrease in stock-based compensation expenses, an $8.8 million decrease in cash compensation expenses driven by decreased bonuses, and a $3.1 million decrease in litigation expenses. This decrease was partially offset by a $10.1 million increase in expenses related to changes in the value of the deferred compensation plan liabilities, and an $8.2 million increase consisting mostly of travel related expenses, third party service expenses and software licensing fees.

Current wording

SG&A expenses were $356.8 million, or 16.2% of revenue, for the year ended December 31, 2024, and $275.7 million, or 15.1% of revenue, for the year ended December 31, 2023. The $81.0 million increase in SG&A expenses was driven by a $50.1 million increase in stock-based compensation expenses and related payroll taxes, a $16.4 million increase in cash compensation expenses and benefits, and a $6.7 million increase in professional services.

Previous wording

The income tax expense for the year ended December 31, 2023 was $78.5 million, or 15.5% of pre-tax income. The effective tax rate was lower than the federal statutory rate of 21% primarily due to foreign income from our subsidiaries in Bermuda and China being taxed at lower statutory tax rates and a return to provision true-up adjustment which primarily resulted from a calculation refinement of our capitalization of research and experimental expenditures under Section 174 of the Internal Revenue Code (the “IRC”). The decrease in the effective tax rate relative to the federal statutory rate was partially offset by the inclusion of the global intangible low-taxed income (“GILTI”) tax, the addition of a valuation allowance against China deferred tax assets arising from the indefinite extension of the R&D super deduction policy in China, and excess tax benefits from stock-based compensation.

The lower effective tax rate relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax, the addition of a valuation allowance against foreign subsidiaries’ deferred tax assets arising from the indefinite extension of an R&D super deduction policy, and excess tax benefits from stock-based compensation.

Previous wording

In December 2023, the Bermuda Corporate Income Tax Act of 2023 (the “Bermuda CIT Act”) was enacted and signed into law. The Bermuda CIT Act includes a 15% corporate income tax (“CIT”) applicable to Bermuda businesses that are multinational enterprise (“MNE”) groups with annual revenue of €750M or more beginning in 2025. The Bermuda CIT Act also includes an Economic Transition Adjustment (“ETA”) that requires MNE’s to revalue their assets and liabilities, excluding goodwill, at their fair value as of September 30, 2023. There is an election to opt out of the ETA. As the Bermuda CIT Act is not effective until January 1, 2025, we are evaluating whether or not to adopt this ETA. Based on information available, we have not recorded any changes to income tax expense related to the Bermuda CIT Act as of December 31, 2023.

Current wording

The Bermuda CIT Act includes a 15% corporate income tax (“CIT”) applicable to Bermuda businesses that are multinational enterprise (“MNE”) groups with annual revenue of €750M or more beginning in 2025. As the Bermuda CIT Act is not effective until January 1, 2025, and we do not expect to realize material taxable income in Bermuda in 2025, no changes to income tax expense related to the Bermuda CIT Act have been recorded as of December 31, 2024.

Previous wording

As of December 31, 2023, we had cash and cash equivalents of $527.8 million and short-term investments of $580.6 million, compared with cash and cash equivalents of $288.6 million and short-term investments of $449.3 million as of December 31, 2022. As of December 31, 2023, $369.9 million of cash and cash equivalents and $528.0 million of short-term investments were held by our international subsidiaries. For the year ended December 31, 2023, we repatriated $140 million of cash from our Bermuda subsidiary to the U.S. with minimal tax impact. The proceeds are primarily used to fund our ongoing business operations. We may repatriate additional cash from our Bermuda subsidiary to fund our expenditures in future periods. We anticipate that earnings from other foreign subsidiaries will continue to be indefinitely reinvested.

Current wording

As of December 31, 2024, we had cash and cash equivalents of $691.8 million and short-term investments of $171.1 million, compared with cash and cash equivalents of $527.8 million and short-term investments of $580.6 million as of December 31, 2023. As of December 31, 2024, $611.9 million of cash and cash equivalents and $164.4 million of short-term investments were held by our foreign subsidiaries. For the years ended December 31, 2024 and 2023, we repatriated $642 million and $140 million, respectively, of cash from a foreign subsidiary to the U.S. with minimal tax impact. The proceeds are primarily used to fund our stock repurchase program, dividend program and ongoing business operations. We may repatriate additional cash from certain foreign subsidiaries to fund our expenditures in future periods. We anticipate that earnings from other foreign subsidiaries will continue to be indefinitely reinvested.

Previous wording

For the year ended December 31, 2023, the $391.5 million increase in cash provided by operating activities compared to the prior period was primarily due to decreased inventory purchases, decreased prepaid wafer expenses, increased accounts receivable collections and other changes in working capital.

Current wording

For the year ended December 31, 2024, the $150.2 million increase in cash provided by operating activities compared to the prior period was primarily due to increased accounts receivable collections, partially offset by increased inventory purchases. The increase was also contributed by the receipt of prepaid wafer expenses in the year ended December 31, 2024 and other changes in working capital.

Previous wording

For the year ended December 31, 2023, the $54.9 million increase in cash used in financing activities compared to the prior period was primarily due to a $47.9 million increase in dividend and dividend equivalent payments.

Current wording

For the year ended December 31, 2024, the $688.5 million increase in cash used in financing activities compared to the prior period was primarily due to a $632.5 million increase in stock repurchases and a $54.8 million increase in dividends and dividend equivalent payments.

Previous wording

Previous report — wording carried elsewhere

The income tax expense for the year ended December 31, 2022 was $87.3 million, or 16.6% of pre-tax income. The effective tax rate was lower than the federal statutory rate of 21% primarily due to foreign income from our subsidiaries in Bermuda and China being taxed at lower statutory tax rates, and excess tax benefits from stock-based compensation. The decrease in the effective tax rate relative to the federal statutory rate was partially offset by the inclusion of the GILTI tax.
