• We continued to prioritize investments prudently in strategic growth areas and advanced technologies.
• We believe that our policies and programs comply with the law in all jurisdictions in which we operate.
• At this time, management does not believe that the outcome of any future or current examination will have a material impact on our consolidated financial statements.
• We believe that we have an adequate provision for any adjustments that may result from tax examinations.
• Although there are no matters pending that we currently believe are probable and reasonably possible of having a material impact to our business, consolidated financial position, or results of operations or cash flows, the outcome of litigation is inherently uncertain and is difficult to predict.

Industry Context

Keysight operates in a highly competitive and rapidly changing global marketplace, driven by continuous technological innovation and increasing engineering intensity. The company's strategic acquisitions in communications test (Spirent), optical solutions (Synopsys OSG), and power analysis (Ansys PowerArtist) reflect a broader industry trend towards expanding integrated design and test capabilities to address emerging technologies like 5G/6G, AI, and advanced automotive systems. The focus on software-centric solutions and recurring revenue aligns with industry shifts towards subscription models and value-added services. Keysight's R&D investments in leading-edge technologies position it to capitalize on secular growth drivers, but it faces intense competition from specialized players and potential consolidation among competitors and customers.

Comparison to Industry Standards

• Keysight's R&D investment of $1,007 million in 2025 (19% of revenue) demonstrates a strong commitment to innovation, comparable to other technology leaders like National Instruments (NI) or Rohde & Schwarz in the test and measurement space, who also heavily invest in R&D to stay ahead in evolving standards (e.g., 5G/6G, automotive radar).
• The acquisition of Spirent Communications plc for $1,564 million significantly enhances Keysight's position in wireless network test and assurance, and positioning technology solutions. This directly competes with companies such as Viavi Solutions Inc. (which acquired parts of Spirent) in network test and assurance, and Anritsu in communications test equipment, indicating a strategic move to consolidate market share in specialized test segments.
• Expanding into design engineering software with Synopsys Optical Solutions Group and Ansys PowerArtist RTL business positions Keysight to compete with established electronic design automation (EDA) software providers like Cadence Design Systems and Synopsys itself, by offering more comprehensive solutions earlier in the customer's design lifecycle. This is a strategic shift to capture value earlier in the product development cycle, a trend seen across the semiconductor and electronics industries.
• The company's focus on AI-driven data center infrastructure (400G/800G Ethernet solutions) aligns with the massive capital expenditures by hyperscalers and enterprise data centers, where companies like Cisco, Arista Networks, and Broadcom are key players. Keysight's test solutions are critical for validating the performance and reliability of these high-speed interconnects, a foundational requirement for AI compute clusters.
• Keysight's diversified market segments (commercial communications, aerospace/defense/government, automotive/energy, semiconductor, general electronics) provide a more resilient business model compared to highly specialized firms, allowing it to weather cyclical downturns in specific sectors, a strategy often adopted by larger, more mature technology companies.

Legal Proceedings

• Centripetal Networks Patent Infringement Lawsuits: A lawsuit filed on January 1, 2022, in Federal District Court in Virginia, alleging infringement of certain Keysight products on Centripetal's patents. Keysight challenged eight patents at the U.S. Patent and Trademark Office, with most claims found invalid, and Centripetal is appealing seven results. The lawsuit is stayed pending appeals. Complaints filed in Germany in February 2022 alleging infringement of three German patents. Two patents were invalidated, and the appeals process ended. The third patent had all but one claim invalidated at trial and is under appeal. A complaint filed with the International Trade Commission (ITC) in April 2022, requesting an investigation into whether Keysight violated Section 337 of the Tariff Act and should be enjoined from importing certain products. On December 5, 2023, the ITC determined Keysight did not unfairly import products, and the investigation was terminated. Centripetal has appealed this determination. A complaint served in Germany on August 21, 2024, filed in the Unified Patent Court, alleging infringement of a European Centripetal patent. In December 2025, the court determined Keysight did not infringe, and the EPO revoked the patent in November 2025. Keysight denies the allegations and is aggressively defending each case, but the outcomes are uncertain and could result in significant monetary damages or injunctive relief.
• U.S. Tax Refund Lawsuit: On January 23, 2025, Keysight filed a lawsuit against the United States of America in the U.S. Court of Federal Claims seeking a tax refund of $107 million (or greater) related to Global Intangible Low-Taxed Income (GILTI) tax deductions for intangible asset amortization. The company believes the U.S. Treasury exceeded its regulatory authority in disallowing these deductions. Keysight intends to vigorously defend its position, but the outcome is uncertain. If unsuccessful, the company would be required to reverse the previously recorded benefit, potentially resulting in a material increase in the effective tax rate and income tax liability.
• Other Litigation: The company is also involved in other lawsuits, claims, investigations, and proceedings, including patent, commercial, and environmental matters, arising in the ordinary course of business, which are not currently believed to have a material impact.

Stakeholder Impact

• Shareholders: Positive impact from increased revenue, net income, and operating cash flow. Potential for increased shareholder returns through the new $1,500 million stock repurchase program. Risk of dilution if future capital raises involve equity issuance. Uncertainty from ongoing litigation and tax disputes could affect stock price.
• Employees: Increased headcount due to acquisitions (approximately 16,800 employees worldwide as of October 31, 2025). Continued investment in R&D and strategic growth areas provides opportunities. Flexible operating model with variable pay mechanisms and strategic use of contingent staffing. Commitment to diversity, inclusion, and employee growth.
• Customers: Benefit from differentiated, first-to-market solutions and expanded portfolio through acquisitions (Spirent, OSG, PowerArtist). Solutions accelerate innovation in 5G/6G, AI, automotive, and defense. Potential for increased product costs due to tariffs.
• Suppliers: Dependence on a global network of suppliers and contract manufacturers. Risks of supply chain disruptions, extended lead times, or increased prices due to capacity constraints or geopolitical factors. Non-cancellable purchase commitments of approximately $450 million.
• Creditors: The company has outstanding debt ($2,534 million) but was in compliance with covenants of senior notes and revolving credit facility as of October 31, 2025. New senior notes issued in 2024 and 2025.

Next Steps

• Finalize the purchase price allocation for Spirent and OSG acquisitions in the second quarter of fiscal year 2026.
• Continue to vigorously defend the Centripetal Networks patent infringement lawsuits in the U.S. and Germany.
• Continue to vigorously defend the lawsuit against the U.S. government for a $107 million tax refund.
