Cisco Systems, Inc. (CSCO) reported strong financial results for the third quarter and first nine months of fiscal 2026, with total revenue reaching $15.8 billion in the quarter—a 12% year-over-year increase—driven by surging demand for AI Infrastructure solutions and broad-based growth across Networking products. The company's Form 10-Q for the period ended April 25, 2026, reveals a business in transition: while capitalizing on the AI investment wave through its Silicon One-based networking equipment and campus modernization cycles, Cisco is simultaneously navigating product mix headwinds, elevated memory costs, a restructuring plan to reallocate resources, and evolving risks related to artificial intelligence, supply chain constraints, and international tax contingencies. This assembled description consolidates the company's revenue performance, profitability trends, liquidity position, market risk exposures, risk factors, legal proceedings, and statutory disclosures into a cohesive narrative.

I. Revenue and Segment Performance

Cisco Systems, Inc. delivered strong top-line performance in the third quarter of fiscal 2026, with total revenue reaching $15.8 billion, a 12% increase compared to the prior-year quarter. Product revenue rose 17% to $12.1 billion, while services revenue declined marginally by 1% to $3.7 billion [Item 2 - MD&A, ¶3]. For the first nine months of fiscal 2026, total revenue grew 10% to $46.1 billion, with product revenue increasing 13% and services revenue remaining essentially flat [Item 2 - MD&A, ¶6].

Product Category Performance. The Networking product category, which comprises switching, routing, wireless, and servers, was the primary growth engine. Networking revenue surged 25% year-over-year, or $1.7 billion, to $8.8 billion in the third quarter, driven by particularly strong demand for AI Infrastructure and Campus Networking solutions [Item 2 - MD&A, ¶4]. Growth was broad-based across the portfolio, with double-digit increases in Campus Switching, Data Center Switching, Wireless, and Service Provider Routing [Item 2 - MD&A, ¶27]. Within Security, revenue was flat at $2.0 billion, as declines in prior-generation products and Splunk offerings—reflecting a customer shift from on-premise deals to cloud subscriptions—were offset by growth in new and refreshed products [Item 2 - MD&A, ¶28]. Collaboration revenue edged down 1% to $1.0 billion, driven by declines in Webex Suite offerings, partially offset by growth in Collaboration Devices and Cloud Contact Center. Observability revenue increased 3% to $269 million, supported by growth in ThousandEyes, partially offset by declines in Splunk offerings [Item 2 - MD&A, ¶29]. Services revenue of $3.7 billion decreased 1%, reflecting lower support services revenue that was partially offset by higher professional services.

Geographic Segment Analysis. Cisco operates three geographic segments: Americas, EMEA, and APJC. In the third quarter, total revenue grew across all segments, with the Americas increasing 14% to $9.6 billion, EMEA rising 9% to $4.1 billion, and APJC growing 9% to $2.2 billion [Item 2 - MD&A, ¶24]. Product revenue in the Americas segment increased 20%, led by the Service Provider and Cloud customer market, which was largely driven by AI Infrastructure solutions [Item 2 - MD&A, ¶25]. Within EMEA, product revenue increased 11%, with growth across all customer markets and particularly strong results in the United Kingdom (up 26%) and Germany (up 7%). In APJC, product revenue rose 14%, with Japan, India, Australia, and China all contributing to the growth [Item 2 - MD&A, ¶26].

Key Drivers and Outlook. The overarching driver of Cisco's revenue growth was surging demand for AI Infrastructure solutions, which fueled large-scale spending by hyperscalers and other service providers on Cisco Silicon One-based networking equipment. Campus Networking also benefited from continued enterprise modernization cycles. However, these positive trends were partly offset by headwinds in the Security portfolio as customers migrated from legacy Splunk on-premise deployments to cloud-based subscriptions. Product gross margin contracted 2.5 percentage points to 61.9%, primarily due to unfavorable product mix from higher Networking revenue and elevated memory costs, partially offset by productivity improvements [Item 2 - MD&A, ¶31]. Cisco continues to navigate a complex environment involving memory supply constraints and evolving trade policies, while investing in key growth areas including silicon, optics, security, and artificial intelligence.

II. Profitability and Margins

Cisco's profitability metrics during the third quarter and first nine months of fiscal 2026 reflected strong operating leverage driven by robust revenue growth, even as gross margins faced headwinds from product mix and rising memory costs. Total gross margin for the third quarter of fiscal 2026 was 63.6%, a decline of 2.0 percentage points compared to 65.6% in the prior-year period, while operating income as a percentage of revenue improved to 25.0%, up 2.4 percentage points year over year [Item 2 - MD&A, ¶3]. For the first nine months of fiscal 2026, total gross margin was 64.7%, down 0.8 percentage points from 65.5%, while operating margin expanded to 24.1%, up 3.4 percentage points versus the prior-year period [Item 2 - MD&A, ¶6].

Gross Margin Trends. Product gross margin declined by 2.5 percentage points in the third quarter, driven primarily by negative product mix—particularly from higher Networking revenue—and higher memory costs, partially offset by productivity improvements and lower amortization of purchased intangible assets [Item 2 - MD&A, ¶31]. For the first nine months, product gross margin decreased by 1.0 percentage point, reflecting similar mix and pricing pressures tempered by productivity gains. Services gross margin, by contrast, improved modestly, increasing by 0.5 percentage points in the third quarter and 0.1 percentage points year-to-date, supported by ongoing cost efficiencies [Item 2 - MD&A, ¶34].

Operating Expenses. Research and development expenses totaled $2,377 million in the third quarter and $7,132 million year-to-date, increasing 2% and 3%, respectively, driven by higher discretionary spending and headcount-related costs reflecting Cisco's continued investments in artificial intelligence, partially offset by lower acquisition-related costs [Item 2 - MD&A, ¶36]. Sales and marketing expenses rose 5% in the quarter to $2,855 million and 6% year-to-date to $8,607 million, driven by higher headcount-related expenses and contracted services. General and administrative expenses declined 11% to $661 million in the quarter and 9% to $2,082 million year-to-date, reflecting lower headcount-related expenses, lower acquisition-related costs, and reduced discretionary spending [Item 2 - MD&A, ¶37]. Collectively, these core operating expenses fell to 37.2% of revenue in the quarter (from 41.0%) and 38.7% year-to-date (from 41.3%), a significant driver of operating margin expansion.

Net Income and Earnings Per Share. Net income rose to $3,373 million in the third quarter, up 35% from $2,491 million a year earlier, and reached $9,408 million for the first nine months, up 23% from $7,630 million [Item 1 - Financial Statements, Table 2]. Diluted earnings per share increased 37% to $0.85 in the quarter and 24% to $2.36 year-to-date, driven by revenue growth and operating margin improvement, though the nine-month comparison was partially tempered by a $720 million tax benefit recorded in the prior fiscal year [Item 2 - MD&A, ¶6]. Operating income grew 24% to $3,960 million in the quarter and 28% to $11,104 million year-to-date [Item 2 - MD&A, ¶40].

Restructuring and Impairment Impacts. In the fourth quarter of fiscal 2026, Cisco announced a new restructuring plan (the "Fiscal 2026 Plan") to reallocate resources toward key growth areas including silicon, optics, security, and artificial intelligence, with estimated total pre-tax charges of up to $1 billion, including approximately $450 million expected in the fourth quarter. The prior restructuring plan (Fiscal 2025 Plan) incurred cumulative charges of $926 million and was substantially completed in the second quarter of fiscal 2026 [Item 2 - MD&A, ¶39]. Additionally, Cisco recorded impairment charges of $19 million in the first nine months of fiscal 2025 related to declines in estimated fair value of certain technology intangible assets, though no comparable impairments were reported in the current period.

III. Liquidity, Capital Resources, and Cash Flow

Cisco's liquidity and capital resources position reflects a robust balance sheet supporting continued investment in strategic growth areas while returning substantial capital to stockholders. During the first nine months of fiscal 2026, net cash provided by operating activities totaled $8.8 billion, which included a final U.S. transition tax payment of $2.3 billion. Investing activities used $3.2 billion, driven by $7.4 billion in purchases of investments partially offset by $5.7 billion in proceeds from sales and maturities and $1.0 billion in capital expenditures. Financing activities consumed $7.3 billion, reflecting $4.9 billion in dividend payments, $4.6 billion in common stock repurchases, $1.4 billion in shares repurchased for tax withholdings on restricted stock units, and $1.8 billion in net debt repayments, partially offset by net commercial paper issuances [Item 2 - MD&A, ¶44].

Cash and cash equivalents stood at $7.1 billion as of April 25, 2026, down from $8.3 billion at the end of fiscal 2025. Total cash and investments, including available-for-sale debt investments of $9.2 billion and marketable equity securities of $0.4 billion, were $16.6 billion, compared to $16.1 billion at July 26, 2025 [Item 1 - Financial Statements, Table 1]. The net increase in total cash and investments was primarily driven by operating cash flows and commercial paper issuances, partially offset by dividends, share repurchases, and capital expenditures.

Cisco manages a well-structured debt portfolio comprising $23.0 billion in aggregate principal of senior fixed-rate notes with maturities through 2064 and $8.4 billion in commercial paper outstanding under a $15.0 billion short-term debt program. An undrawn $5.0 billion unsecured revolving credit facility is also available, requiring an interest coverage ratio of at least 3.0 to 1.0, and the company was in compliance with all debt covenants as of April 25, 2026 [Item 2 - MD&A, ¶54]. Working capital reflected $36.6 billion in current assets and $39.5 billion in current liabilities, the latter notably influenced by $11.9 billion in short-term debt including commercial paper and the current portion of long-term debt [Item 1 - Financial Statements, Table 1].

The company generated free cash flow of $7.8 billion in the first nine months of fiscal 2026, defined as net cash provided by operating activities less capital expenditures. As part of its capital allocation strategy, Cisco targets returning a minimum of 50% of free cash flow to stockholders annually through dividends and share repurchases [Item 2 - MD&A, ¶46]. On May 13, 2026, Cisco's Board declared a quarterly dividend of $0.42 per common share. Total dividends paid in the first nine months of fiscal 2026 were $4.9 billion, and share repurchase activity totaled $4.6 billion during the same period, with $9.6 billion remaining under the authorized repurchase program as of April 25, 2026 [Item 2 - MD&A, ¶48]. Management believes that existing cash, cash equivalents, investments, cash from operations, and access to capital markets will be sufficient to satisfy liquidity requirements for at least the next 12 months [Item 2 - MD&A, ¶58].

IV. Market Risk Exposures

Cisco's financial position is exposed to several categories of market risk, including interest rate risk, equity price risk, and foreign currency exchange risk. The company formally addresses these exposures in its Quantitative and Qualitative Disclosures About Market Risk, and underlying operational impacts are discussed within Management's Discussion and Analysis [Item 3 - Market Risk, ¶1].

Interest Rate Risk. Cisco maintains an investment portfolio of available-for-sale debt investments with the primary objective of preserving principal while managing risk. As of April 25, 2026, the company held $9.2 billion in available-for-sale debt investments, all of which are investment-grade securities and not leveraged. A sharp rise in market interest rates could materially adversely impact the fair value of this portfolio, while a decline in rates could reduce interest income [Item 3 - Market Risk, ¶1]. In the third quarter of fiscal 2026, interest income decreased year-over-year, driven by a lower average balance of cash and available-for-sale debt investments and lower prevailing interest rates [Item 2 - MD&A, ¶41].

Cisco's financing receivables totaled $6.6 billion in carrying value as of April 25, 2026. Under a hypothetical 50 basis point (BPS) change in market interest rates, the fair value of these receivables would shift by approximately $0.1 billion [Item 3 - Market Risk, ¶2]. Additionally, Cisco had $23.0 billion in principal amount of senior fixed-rate notes outstanding, with a carrying value of $22.9 billion and a fair value of $23.3 billion. A hypothetical 50 BPS change in market interest rates would alter the fair value of this fixed-rate debt by approximately $0.7 billion, though it would not affect interest expense on these obligations since the rates are fixed [Item 3 - Market Risk, ¶2]. Cisco had $8.4 billion in commercial paper outstanding as of April 25, 2026, and an additional $15.0 billion available under its commercial paper program, meaning a rise in short-term interest rates could increase interest expense on future commercial paper issuances.

Equity Price Risk. Cisco's marketable equity securities totaled $377 million in fair value as of April 25, 2026, held for strategic purposes rather than trading. The company also held $2.9 billion in non-marketable equity securities, many of which are in startup or development-stage companies that carry inherent risk of total loss [Item 3 - Market Risk, ¶3].

Foreign Currency Exchange Risk. Cisco conducts business globally, but revenue is primarily denominated in U.S. dollars, making the direct effect of foreign currency movements on revenue not material. However, approximately 75% of operating expenses are U.S.-dollar denominated, while the remainder is exposed to currency fluctuations. In the first nine months of fiscal 2026, foreign currency fluctuations, net of hedging, increased combined R&D, sales and marketing, and G&A expenses by approximately $181 million, or 1.0%. In the third quarter alone, the impact was $90 million, or 1.6% [Item 3 - Market Risk, ¶4] [Item 2 - MD&A, ¶38].

Hedging Strategies. To mitigate the variability from non-U.S.-dollar-denominated operating expenses and service cost of sales, Cisco enters into foreign currency forward and option contracts. These programs are designed to reduce short-term volatility rather than provide long-term protection. Cisco also uses forward and option contracts to reduce the impact of currency movements on receivables and payables denominated in foreign currencies. The company does not use these instruments for speculative purposes [Item 3 - Market Risk, ¶5]. As of April 25, 2026, Cisco held $4.2 billion in purchased forward contracts (fair value of -$75 million) and $4.7 billion in sold forward contracts (fair value of $79 million) [Item 3 - Market Risk, Table 90]. These positions are designed so that gains and losses on the hedge instruments offset currency-driven movements in underlying operating expenses and balance sheet exposures.

V. Risk Factors and Legal Proceedings

Updated Risk Factors

Cisco's quarterly report on Form 10-Q for the period ended April 25, 2026, includes material changes to the risk factors previously disclosed in its Annual Report on Form 10-K, which supersede the earlier descriptions [Item 1A - Risk Factors, ¶1]. Several notable updates warrant attention.

Supply Chain and Component Constraints. The company continues to face significant supply chain pressures, particularly related to memory components. Manufacturing capacity and component supply constraints experienced in the first nine months of fiscal 2026 have adversely impacted Cisco's product gross margins, and the company expects these pressures to continue [Item 1A - Risk Factors, ¶13]. In response, Cisco entered into additional purchase commitments with contract manufacturers and suppliers during fiscal 2025 and the first nine months of fiscal 2026, including commitments related to Cisco Silicon One, memory components, and other products to meet demand from hyperscalers and other customers [Item 1A - Risk Factors, ¶14]. These efforts have significantly increased the company's supply chain exposure.

Supplier Legal Dispute. On August 26, 2025, Cisco settled a legal dispute with a supplier relating to purchase obligations arising under long-term supply arrangements, which resulted in a charge to product cost of sales in the fourth quarter of fiscal 2025 [Item 1A - Risk Factors, ¶15]. This dispute underscores the financial risks associated with the company's extended supply chain and purchase commitment obligations.

Artificial Intelligence Risks. For the first time in this quarterly filing, Cisco highlights significant risks related to the development and use of artificial intelligence. The company incorporates AI technology in certain commercial offerings and business operations, but acknowledges that AI algorithms and training methodologies may be flawed, and the AI-related legal and regulatory landscape is complex and evolving across jurisdictions [Item 1A - Risk Factors, ¶29]. These factors could result in legal or regulatory action, reputational damage, and increased compliance costs.

Restructuring Plan. Cisco initiated a new restructuring plan in the fourth quarter of fiscal 2026, expected to be substantially completed by the end of fiscal 2027, as part of its ongoing efforts to realign resources in response to changing industry and market conditions [Item 1A - Risk Factors, ¶41].

Legal Proceedings

Brazil Tax Claims. Brazilian tax authorities have asserted substantial claims against Cisco's Brazilian subsidiary based on a theory of joint liability with a Brazilian importer for alleged evasion of import taxes. The remaining asserted claims aggregate to approximately $155 million for alleged taxes, $966 million in interest, and $320 million in penalties. Cisco believes these claims are without merit and is defending them vigorously, though it notes that a final judicial determination is not expected for several years [Item 1 - Financial Statements, ¶45].

Centripetal Patent Litigation. In the multi-jurisdictional patent litigation brought by Centripetal Networks, Inc., Cisco achieved a significant victory on April 29, 2026, when the U.S. Federal Circuit affirmed the District Court's non-infringement decision. Related proceedings in Germany and France remain ongoing, with the German court having issued a preliminary opinion that Cisco does not infringe [Item 1 - Financial Statements, ¶46].

Ramot Patent Litigation. Ramot at Tel Aviv University Ltd. has asserted patent infringement claims against Cisco and Acacia relating to optical transceiver modules and line cards. The District Court for the District of Delaware granted Cisco's motion for summary judgment of non-infringement, which Ramot has appealed to the Federal Circuit. While Cisco believes it has strong non-infringement and invalidity arguments, it is unable to reasonably estimate the ultimate outcome; however, any damages ultimately assessed are not expected to have a material effect on the financial statements [Item 1 - Financial Statements, ¶47].

Assessment of Financial Impact

With respect to the legal proceedings described above, Cisco states that while the ultimate outcomes are not determinable in certain cases, it does not believe that the costs to resolve these matters will have a material effect on its Consolidated Financial Statements. Similarly, the company maintains a liability of $209 million for firm, noncancelable purchase commitments in excess of forecasted demand, reflecting its assessment of known contingencies as of the balance sheet date [Item 1 - Financial Statements, ¶40].

VI. Disclosure Controls, Procedures, and Other Statutory Items

Evaluation of Disclosure Controls and Procedures

Cisco's management, with the participation of its principal executive officer and principal financial officer, evaluated the effectiveness of the company's disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the principal executive officer and principal financial officer concluded that Cisco's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective. These controls ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by SEC rules and forms, and that such information is accumulated and communicated to management to allow timely decisions regarding required disclosure [Item 4 - Controls, ¶1].

Changes in Internal Control over Financial Reporting

During the third quarter of fiscal 2026, there was no change in Cisco's internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, the company's internal control over financial reporting [Item 4 - Controls, ¶1].

Unregistered Sales of Equity Securities and Defaults

Cisco reported that there were no unregistered sales of equity securities during the quarter and no defaults upon senior securities [Item 2 - Equity Sales, ¶1]. However, the company continued its long-standing stock repurchase program during the period. Under the program originally authorized by the Board of Directors on September 13, 2001, Cisco repurchased 16 million shares of common stock during the third quarter of fiscal 2026 at an average price of $80.28 per share, for a total of approximately $1.3 billion. As of April 25, 2026, the remaining authorized amount for stock repurchases under this program was approximately $9.6 billion with no termination date [Item 2 - Equity Sales, ¶1] [Item 2 - Equity Sales, Table 91].

Other Information — Rule 10b5-1 Trading Arrangements

During the quarter, three of Cisco's executive officers adopted trading plans intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. On February 18, 2026, Charles H. Robbins, Cisco's Chair and Chief Executive Officer, adopted a trading plan providing for the sale of up to 494,027 gross shares (with shares underlying performance-based equity awards calculated at target), plus related dividend-equivalent shares. Mr. Robbins' plan is scheduled to terminate on March 27, 2027, subject to early termination upon certain specified events [Item 5 - Other Info, ¶1]. On February 20, 2026, M. Victoria Wong, Cisco's Senior Vice President and Chief Accounting Officer, adopted a trading plan providing for the sale of up to 21,150 gross shares, plus related dividend-equivalent shares and shares from the employee stock purchase plan. Ms. Wong's plan is also scheduled to terminate on March 27, 2027 [Item 5 - Other Info, ¶2]. On March 17, 2026, Thimaya Subaiya, Cisco's Executive Vice President, Operations, adopted a trading plan providing for the sale of up to 74,487 gross shares, with the same termination date of March 27, 2027 [Item 5 - Other Info, ¶3]. No other material information was required to be disclosed under Item 5 of Part II for the period.

Conclusion

Cisco Systems, Inc.'s third-quarter fiscal 2026 results portray a company riding a powerful AI-driven demand wave while carefully managing the operational complexities that come with it. The 25% surge in Networking revenue—fueled by hyperscaler spending on Cisco Silicon One-based infrastructure—drove strong top-line growth and operating margin expansion, even as product gross margins faced compression from unfavorable mix and elevated memory costs. Looking ahead, Cisco's newly announced restructuring plan signals a deliberate pivot toward silicon, optics, security, and AI as the company positions its portfolio for the next cycle of technology investment. With a solid liquidity position, disciplined capital allocation returning substantial cash to stockholders, and an effective control environment, Cisco appears well-equipped to navigate its disclosed risks, including supply chain constraints, AI regulatory uncertainty, and international tax contingencies, as it executes on its growth strategy in the quarters ahead.
