Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes included in "Part II, Item 8. Financial Statements and Supplementary Data" of this Annual Report.
The following section generally discusses fiscal 2025 and 2024 items and year-to-year comparisons between fiscal 2025 and 2024. Discussions of fiscal 2023 items and year-to-year comparisons between fiscal 2024 and 2023 that are not included in this Annual Report can be found in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended September 29, 2024.
Our Business and Operating Segments
We develop and commercialize foundational technologies and products used across industries and applications from mobile devices to other areas including automotive and the internet of things (IoT). We derive revenues principally from sales of integrated circuit products and licensing our intellectual property, including patents and other rights.
We are organized on the basis of products and services and have three reportable segments. We conduct business primarily through our QCT (Qualcomm CDMA Technologies) semiconductor business and our QTL (Qualcomm Technology Licensing) licensing business. Our QSI (Qualcomm Strategic Initiatives) reportable segment makes strategic investments. We also have nonreportable segments, including QGOV (Qualcomm Government Technologies) and our Data Center business (formerly referred to as our cloud computing processing initiative).
Further information regarding our business and operating segments is provided in "Part I, Item 1. Business" of this Annual Report.
Seasonality. Many of our products and much of our intellectual property are incorporated into consumer wireless devices, which are subject to seasonality and other fluctuations in demand. Our revenues have historically fluctuated based on consumer demand for devices, as well as on the timing of customer/licensee device launches and/or innovation cycles (such as the transition to the next generation of wireless technologies). This has resulted in fluctuations in QCT revenues in advance of and during device launches incorporating our products (for example, certain major handset OEMs accelerated their premium-tier device launches into the first quarter of fiscal 2025) and in QTL revenues when licensees' sales occur. These trends may or may not continue in the future. Further, the trends for QTL have been, and may in the future be, impacted by disputes and/or resolutions with licensees and/or governmental investigations or proceedings.

Fiscal 2025 Overview
Revenues were $44.3 billion, an increase of 14% compared to revenues of $39.0 billion in fiscal 2024, with net income of $5.5 billion, a decrease of 45% compared to net income of $10.1 billion in fiscal 2024. Key items from fiscal 2025 included:
•QCT revenues increased by 16% in fiscal 2025 compared to the prior year, primarily due to higher handsets, IoT and automotive revenues.
•QTL revenues remained approximately flat in fiscal 2025 compared to the prior year.
•We recorded a charge of $5.7 billion to income tax expense to establish a valuation allowance in the fourth quarter of fiscal 2025 as we no longer expect to realize substantially all of our existing federal deferred tax assets as a result of the tax reform legislation included in the One Big Beautiful Bill Act (OBBB) enacted on July 4, 2025.

Income Tax Expense (in millions, except percentages)
The following table summarizes the primary factors that caused our annual tax provision from continuing operations to differ from the expected income tax provision at the U.S. federal statutory rate. Substantially all of our income is taxed in the U.S., of which a significant portion qualifies for preferential treatment as foreign-derived intangible income (FDII) at a 13% effective tax rate for the periods presented. Additional information regarding our annual effective tax rate (including discussion related to the impact of the requirement to capitalize research and development expenditures for federal income tax purposes, and the benefit related to the transfer of intellectual property between foreign subsidiaries in fiscal 2024) is provided in this Annual Report in "Notes to Consolidated Financial Statements, Note 3. Income Taxes."

Income tax expense$7,122 $226
Effective tax rate56%2%
On July 4, 2025, tax reform legislation included in the OBBB was enacted in the United States. The OBBB includes significant corporate tax reforms, including the permanent reinstatement of deducting domestic research and development expenditures as incurred beginning in fiscal 2026 (under prior law such expenditures were capitalized and amortized over five years). The legislation also modifies international tax provisions, including changes to the FDII regime. Specifically, it renames FDII as Foreign-Derived Deduction Eligible Income (FDDEI), maintains the current FDDEI effective tax rate of 13% through fiscal 2026 and adjusts the FDDEI effective tax rate to a permanent 14% rate in fiscal 2027 (compared to 16% under prior law). As a result of these changes, we expect to be subject to the corporate alternative minimum tax (CAMT) beginning in fiscal 2026. CAMT imposes a 15% federal minimum tax on adjusted financial statement income, reduced by general business credits, including research and development credits. As we expect to perpetually be subject to CAMT, we no longer expect to realize substantially all of our existing federal deferred tax assets and recognized a charge of $5.7 billion to income tax expense to establish a valuation allowance in the fourth quarter of fiscal 2025.
Beginning in fiscal 2023 and through fiscal 2025, for federal income tax purposes, we were required to capitalize and amortize domestic research and development expenditures over five years (such expenditures were previously deducted as incurred). Our cash flows from operations were adversely affected due to significantly higher cash tax payments. However, since the resulting deferred tax asset was established at the statutory rate of 21% (rather than the current effective tax rate of 13% after considering the FDII deduction), capitalization favorably affected our total provision for income taxes and results of operations. With the enactment of OBBB, such impacts on our cash flows and tax provision are not expected to continue beginning in fiscal 2026. Changes in future taxable income (including less of our income qualifying for preferential treatment as FDDEI), tax laws (including changes to the CAMT rules) and other factors may change our determination regarding whether we will be able to realize our deferred tax assets.

Segment Results
The following should be read in conjunction with the fiscal 2025 and 2024 results of operations for each reportable segment included in this Annual Report in "Notes to Consolidated Financial Statements, Note 8. Segment Information."

(1) Descriptions of our three QCT revenue streams can be found in this Annual Report in "Notes to Consolidated Financial Statements, Note 2. Composition of Certain Financial Statement Items."
(2) Earnings before income taxes.
Substantially all of QCT's revenues consist of equipment and services revenues, which were $37.7 billion and $32.6 billion in fiscal 2025 and 2024, respectively. QCT revenues mostly relate to sales of our Snapdragon and Dragonwing platforms (which include processors and modems), stand-alone Mobile Data Modems, radio frequency transceiver, power management and wireless connectivity integrated chipsets as well as sales of 4G, 5G sub 6 and 5G millimeter wave RFFE products.
2025 vs. 2024
The increase in QCT revenues in fiscal 2025 was primarily due to:
higher handsets revenues, due to $2.5 billion in higher revenues per chipset primarily driven by higher average selling prices and favorable mix, and $423 million in higher chipset shipments by certain major OEMs, both of which benefited from an increase in demand for premium-tier Snapdragon platforms in Android devices
higher IoT revenues due to $1.5 billion in higher shipments across edge networking, consumer and industrial products, partially offset by unfavorable mix
higher automotive revenues, primarily driven by an increase in shipments from new vehicle launches with our Snapdragon digital cockpit products
QCT EBT as a percentage of revenues increased in fiscal 2025 primarily due to:
- higher operating expenses, primarily driven by higher selling, general and administrative expenses
Gross margin percentage remained approximately flat in fiscal 2025, primarily driven by higher product costs, partially offset by higher average selling prices.

QTL licensing revenues and EBT remained approximately flat in fiscal 2025. During the second quarter of fiscal 2025, we executed final agreements for new long-term licenses with two key Chinese OEMs (for which the initial terms had expired) and entered into comprehensive 4G and 5G license agreements with Transsion (a growing, China-headquartered OEM that sells primarily in developing regions). As a result of our agreements with Transsion, all outstanding litigation between the parties has been dismissed. Beginning in the second quarter of fiscal 2025, QTL revenues did not include royalties from Huawei, whose license agreement has expired.

Looking Forward
We believe that on-device AI and high-performance, low-power computing combined with cellular technology (such as 5G) will continue to drive adoption of certain technologies that are already commonly used in smartphones by industries and applications beyond mobile handsets, such as automotive and IoT. We believe it is important that we remain a leader in such technology development, standardization, intellectual property creation and licensing, and a leading developer and supplier of integrated circuit products in order to sustain and grow our business long-term.
As we look forward to the next several quarters:
•We continue to monitor the recent changes in global trade policy, including tariffs and related trade actions announced by the U.S., China and other countries. The degree to which such tariffs and other related actions impact our business, financial condition and results of operations will depend on future developments, which are uncertain. Changes to global trade policies may negatively impact demand, pricing and cost for our products and technologies, and contribute to the inherent uncertainties in estimating future customer demand, which may result in increased excess or obsolete inventory or reserve charges, negatively impacting our results of operations and cash flows. See "Part I, Item 1A. Risk Factors" in this Annual Report, including the Risk Factor titled "We operate in the highly cyclical semiconductor industry, which is subject to significant downturns. We are also susceptible to declines in global, regional and local economic conditions generally. Our stock price and financial results are subject to substantial quarterly and annual fluctuations due to these dynamics, among others."
•We expect leading process technology nodes to continue to drive product cost increases from certain of our key semiconductor wafer suppliers.
•We expect continued intense competition, including from vertical integration by certain of our customers (for example, Apple and Samsung). In particular, Apple began utilizing its own modem (rather than our products) in its recently released smartphones and we expect that Apple will increasingly use its own modem products, rather than our products, in its future devices, which will have a significant negative impact on our QCT revenues, results of operations and cash flows.
•We expect to continue investing in key growth and diversification initiatives. We also expect our share-based compensation expense to increase as we have replaced our annual cash incentive awards for fiscal 2026 and 2027 with a two-year equity award for our broader non-executive leadership team. This approach is designed to motivate and retain our team to execute our long-term diversification strategy, while further aligning their compensation with the interests of our stockholders.
•U.S./China trade relations and/or national security protection policies may negatively impact our business, growth prospects and results of operations. See "Part I, Item 1A. Risk Factors" in this Annual Report, including the Risk Factor titled "A significant portion of our business is concentrated in China, and the risks of such concentration are exacerbated by U.S./China trade and national security tensions."
We are also involved in certain legal proceedings, including those described in this Annual Report in "Notes to Consolidated Financial Statements, Note 7. Commitments and Contingencies." Litigation is inherently uncertain, and, while we intend to continue to vigorously defend ourselves in such matters, the unfavorable resolution of one or more of these matters could have a material adverse effect on our business, results of operations, financial condition or cash flows.
In addition to the foregoing business and market-based matters, we continue to devote resources to working with and educating participants in the wireless industry and governments as to the benefits of our licensing programs and our extensive technology investments in promoting a highly competitive and innovative wireless industry. However, we expect that certain companies may be dissatisfied with the need to pay reasonable royalties for the use of our technologies and not welcome the success of our licensing programs in enabling new, highly cost-effective competitors to their products. Accordingly, such companies, and/or governments or regulators, may continue to challenge our business model in various forums throughout the world.
Further discussion of risks related to our business is provided in "Part I, Item 1A. Risk Factors" included in this Annual Report.

Liquidity and Capital Resources
Our principal sources of liquidity are our existing cash, cash equivalents and marketable securities (including restricted cash), cash generated from operations and cash provided by our debt programs, which we believe will satisfy our working and other capital requirements for at least the next 12 months based on our current business plans.
The following table presents selected financial information related to our liquidity as of and for the years ended September 28, 2025 and September 29, 2024 (in millions):

Additional information regarding our pending acquisition of Alphawave is provided in this Annual Report in "Notes to Consolidated Financial Statements, Note 9. Acquisitions."
(2) Includes our issued debt reported as long-term and short-term. At September 28, 2025, we had $15.1 billion of principal fixed-rate notes outstanding with maturity dates between 2027 and 2053.

(800)(3,623)2,823
Net cash used by financing activities(13,196)(9,269)(3,927)
Cash, cash equivalents and marketable securities (including restricted cash). The net decrease in cash, cash equivalents and marketable securities (including restricted cash) in fiscal 2025 was primarily due to $8.8 billion in payments to repurchase shares of our common stock, $3.8 billion in cash dividends paid, $1.4 billion repayment of unsecured fixed-rate notes that matured in May 2025, $1.2 billion in capital expenditures, $1.1 billion in payments of tax withholdings related to the vesting of share-based awards and $743 million in cash paid for acquisitions and other investments. This was partially offset by cash provided by operating activities, proceeds from the issuance of $1.5 billion of unsecured fixed-rate notes in May 2025 and $404 million in proceeds from the issuance of common stock (primarily under our Employee Stock Purchase Plan).
During fiscal 2025, income taxes paid were less than our provision. This was driven primarily by the $5.7 billion charge to income tax expense to establish a valuation allowance in fiscal 2025 as a result of the tax reform legislation included in the OBBB. This was partially offset by our installment payment for a one-time U.S. repatriation tax accrued in fiscal 2018 of $530 million and the adverse impact of the requirement to capitalize and amortize research and development expenditures for federal income tax purposes. The enactment of the OBBB includes significant corporate tax reforms, including the permanent reinstatement of deducting domestic research and development expenditures as incurred beginning in fiscal 2026. We expect this change will have a favorable effect on our cash flows from operations due to lower cash tax payments compared to fiscal 2025 beginning in fiscal 2026.
Net changes in our operating assets and liabilities positively impacted our operating cash flows in fiscal 2025 primarily from a decrease in other assets driven by the utilization of prior advanced supply agreement payments, partially offset by an increase in accounts receivables primarily driven by higher revenues.
Debt. During the third quarter of fiscal 2025, we repaid $1.4 billion of unsecured fixed-rate notes that matured in May 2025. In May 2025, we also issued $1.5 billion of unsecured fixed-rate notes, consisting of $500 million of 4.50% notes, $400 million of 4.75% notes and $600 million of 5.00% notes (collectively, May 2025 Notes) that mature on May 20, 2030, May 20, 2032 and May 20, 2035, respectively. The net proceeds from the May 2025 Notes will be used for general corporate purposes. We also entered into interest rate swaps which are designated as fair value hedges and allow us to effectively convert all of our fixed-rate payments due under the May 2025 Notes into floating-rate payments.
We have an unsecured commercial paper program, which provides for the issuance of up to $4.5 billion of commercial paper. Net proceeds from this program are used for general corporate purposes. At September 28, 2025, we had no amounts of commercial paper outstanding. We also have a Revolving Credit Facility that provides for unsecured revolving facility loans, swing line loans and letters of credit in an aggregate amount of up to $4.0 billion, which expires on August 8, 2029. At September 28, 2025, no amounts were outstanding under the Revolving Credit Facility.
44
We expect to issue new debt in the future. The amount and timing of any such new debt will depend on a number of factors, including but not limited to maturities of our existing debt, acquisitions and strategic investments, favorable and/or acceptable interest rates and changes in corporate income tax law. Additional information regarding our debt is provided in this Annual Report in "Notes to Consolidated Financial Statements, Note 6. Debt."
Capital Return Program. The following table summarizes stock repurchases (including excise taxes paid) and dividends paid during fiscal 2025 and 2024 (in millions, except per-share amounts):
Stock Repurchase ProgramDividendsTotal
SharesAverage Price Paid Per ShareAmountPer ShareAmountAmount

202425 161.37 4,121 3.30 3,687 7,808
At September 28, 2025, $7.2 billion remained authorized for repurchase under our stock repurchase program. Our stock repurchases were at an increased level in fiscal 2025 compared to fiscal 2024. The timing of future stock repurchases and the number of shares of common stock to be repurchased will depend upon prevailing market conditions and other factors. Repurchases may be made in the open market, through 10b5-1 programs, through accelerated share repurchase programs, in privately negotiated transactions or through the use of derivative instruments. Our stock repurchase programs are subject to periodic evaluations to determine when and if repurchases are in the best interests of our stockholders, and we may accelerate, suspend, delay or discontinue repurchases at any time.
We currently intend to continue to use cash dividends as a means of returning capital to stockholders, subject to capital availability and our view that cash dividends are in the best interests of our stockholders, among other factors. Additional information regarding our capital returns is provided in this Annual Report in "Notes to Consolidated Financial Statements, Note 4. Capital Stock."
Additional Capital Requirements. Recent and expected working and other capital requirements, in addition to the above matters, also include the items described below:
•Our purchase obligations at September 28, 2025, which primarily relate to purchase commitments with certain suppliers of our integrated circuit products, including those under multi-year capacity commitments, totaled $15.1 billion, of which, $10.5 billion is expected to be paid in the next 12 months.
•Our research and development expenditures were $9.0 billion in fiscal 2025 and $8.9 billion in fiscal 2024.
•Cash outflows for capital expenditures were $1.2 billion in fiscal 2025 and $1.0 billion in fiscal 2024. We expect capital expenditures to increase from fiscal 2025 in the near term primarily to support the testing of our integrated circuits.
•Amounts related to future lease payments for operating lease obligations at September 28, 2025 totaled $1.1 billion, with $142 million expected to be paid within the next 12 months.
•On June 9, 2025, we announced that we reached an agreement to acquire Alphawave at an implied enterprise value of approximately $2.4 billion (as of the announcement date). The purchase price will be paid in cash or, if validly elected by eligible shareholders of Alphawave, in shares of our common stock or securities exchangeable for shares of our common stock. The acquisition is subject to certain closing conditions, including receipt of regulatory approvals. Subject to the satisfaction of these conditions, this acquisition is expected to complete during the first quarter of calendar 2026.
•We expect to continue making strategic investments and acquisitions, the amounts of which could vary significantly.
Further, regulatory authorities in certain jurisdictions have investigated our business practices and instituted proceedings against us, and they or other regulatory authorities may do so in the future. Additionally, certain of our direct and indirect customers and licensees have pursued, and they or others may in the future pursue, litigation, arbitration or other strategies against us related to our business. Unfavorable resolutions of one or more of these matters have had and could in the future have a material adverse effect on our business, results of operations, financial condition and cash flows. See "Notes to Consolidated Financial Statements, Note 7. Commitments and Contingencies" and "Part I, Item 1A. Risk Factors" in this Annual Report.
Critical Accounting Estimates
The preparation of our consolidated financial statements in accordance with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent amounts. We base our estimates on historical and anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. By their nature, estimates are inherently subject to a degree of uncertainty. Although we believe that our estimates and the assumptions supporting our assessments are reasonable, actual results could differ materially from our estimates and assumptions, and could be material to our consolidated financial statements.
45
In addition to our critical accounting estimates and policies below, refer to "Note 1. Significant Accounting Policies" and "Note 2. Composition of Certain Financial Statement Items" included in this Annual Report in "Notes to Consolidated Financial Statements" for further information. If the impact of changes in our critical accounting estimates is material or considered necessary to understand our results of operations for the periods presented, then such information is disclosed within this Annual Report in "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations."
Revenue Recognition. We grant licenses or otherwise provide rights to use portions of our intellectual property portfolio, which, among other rights, includes certain patent rights essential to and/or useful in the manufacture, sale or use of certain wireless products. We estimate and recognize sales-based royalties on such licensed products in the period in which the licensees' sales occur, which is based largely on preliminary royalty estimates provided by our licensees. For fiscal 2025 and 2024, actual amounts for sales-based royalties have been materially consistent with such estimates, and no significant reversals of revenues have been required as a result of adjustments to prior period royalty estimates.
Impairment of Non-marketable Equity Investments. We monitor our investments, many of which are in early-stage companies, for events or circumstances that could indicate impairment, including those that result from observable price adjustments. Key considerations in this assessment include the investee's financial and liquidity position and business forecasts (including their ability to respond to any significant deterioration), industry performance, development and/or market acceptance of the investee's products or technologies, as well as considering any appreciation in fair value that has not been recognized in the carrying values of such investments and other relevant events and factors. Measurement of any impairments may require the use of unobservable inputs. In fiscal 2025 and 2024, there were no significant impairment losses or adjustments to our previous judgments and estimates recorded.
Inventories. We measure inventory at the lower of cost or net realizable value considering judgments and estimates related to future customer demand and other market conditions, such as the impact of the macroeconomic environment and global trade policies. Although we believe these estimates are reasonable, any significant changes in customer demand that are less favorable than our previous estimates may require additional inventory write-downs and would be reflected in cost of sales resulting in a negative impact to our gross margin in that period. For fiscal 2025 and 2024, the net effect from changes in this estimate and related reserves was less than 1% of cost of revenues during each period.
Impairment of Goodwill, Other Indefinite-Lived Assets and Long-Lived Assets. We monitor our goodwill, other indefinite-lived assets and long-lived assets for the existence of impairment indicators and apply judgments in the valuation methods (generally income or market approach) and underlying inputs and assumptions utilized in such assessments, which are generally unobservable inputs. During fiscal 2025 and 2024, there were no material impairment charges for long-lived or indefinite-lived assets. Additionally, the estimated fair values of our QCT and QTL reporting units, based on our qualitative assessment, were substantially in excess of their respective carrying values at September 28, 2025.
Legal and Regulatory Proceedings. We are currently involved in certain legal and regulatory proceedings, the outcomes of which are inherently uncertain. If there is at least a reasonable possibility that a material loss may have been incurred associated with pending legal and regulatory proceedings, we disclose such fact. We record our best estimate of a loss related to pending legal and regulatory proceedings when the loss is considered probable and the amount can be reasonably estimated. We face difficulties in evaluating or estimating likely outcomes and/or the amount of possible loss in certain legal and regulatory proceedings. Until the final resolution of such matters, there may be an exposure to loss in excess of the amount recorded (or the possible loss disclosed), and such amounts could be material.
Income Taxes. We make significant judgments and estimates in determining our provision for income taxes, including our assessment of our income tax positions, both in the U.S. and foreign jurisdictions, given the uncertainties involved in the interpretation and application of complex tax laws and regulations in various taxing jurisdictions. While we believe we have appropriate support for the positions we have taken or plan to take on our tax returns, we regularly assess the potential outcomes of examinations by taxing authorities in determining the adequacy of our provision for income taxes based on the technical merits of the position. The actual liability for U.S. or foreign taxes may be materially different from our estimates, which could result in the need to record additional tax liabilities or potentially reverse previously recorded tax liabilities. Based on our results for fiscal 2025, an assumed one-percentage point increase to our annual effective tax rate would result in an increase in income tax expense of $127 million.
Deferred tax assets represent amounts available to reduce income taxes payable on taxable income in future years. Under the OBBB enacted in July 2025, we expect to be subject to CAMT beginning in fiscal 2026 and therefore, we no longer expect to realize substantially all of our existing federal deferred tax assets. As a result, we recorded a charge of $5.7 billion to income tax expense to establish a valuation allowance against such deferred tax assets in the fourth quarter of fiscal 2025. Factors considered in this determination included assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies, and considering that substantially all of our income is taxed in the U.S., of which a significant portion qualifies for preferential treatment as FDDEI. Changes in future taxable income (including less of our income qualifying for preferential treatment as FDDEI), tax laws (including changes to the CAMT rules) and other factors may change our determination regarding whether we will be able to realize our deferred tax assets.
