Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 36% year-over-year (YoY) in Q3 and 31% for the nine-month period. Growth was driven by higher volume, favorable product mix, and contributions from recent acquisitions (Spirent, Synopsys OSG, Ansys PowerArtist).
- Margin Expansion: Gross margin improved by 4 percentage points in Q3 and 3 percentage points for the nine months. Operating margin expanded significantly (8 ppts in Q3, 5 ppts for 9M) due to gross margin gains and operating leverage.
- Tax Impact: The effective tax rate for the nine months ended July 31, 2026, was 6.0%, significantly lower than the 18.8% in the prior year. This was driven by a $97M net benefit from a favorable audit settlement and a $19M release of reserves due to statute of limitations expirations.
- Acquisition Activity: The company completed the acquisition of Spirent Communications plc in Q4 2025, which contributed $61M in incremental revenue in Q3 2026. Additional acquisitions of Synopsys' Optical Solutions Group and Ansys' PowerArtist expanded the software portfolio.
- Tariff Refunds: Following a Supreme Court ruling invalidating certain IEEPA tariffs, the company recorded a $100M receivable for refunds. This resulted in a $93M reduction in cost of sales and a $40M revenue reduction due to customer surcharge refunds, netting a positive impact on operating income.
Guidance, Outlook, and Risks
- Outlook: Management remains confident in long-term secular growth trends, citing continued R&D investment by customers in AI, 5G/6G, quantum computing, and defense. The company expects to maintain R&D expenditures to deliver innovative solutions.
- Capital Allocation: The company repurchased $520M of stock in the first nine months of 2026. A new $1.5B repurchase program was approved in November 2025, with $983M remaining available as of July 31, 2026.
- Key Risks:
- Trade & Tariffs: Ongoing uncertainty regarding U.S. tariff policies, including new "forced labor" tariffs and Section 301 investigations, poses risks to supply chains and costs.
- Legal Proceedings: Ongoing litigation with Centripetal Networks regarding patent infringement. While Keysight has won several key rulings (USPTO, ITC, UPC), appeals remain pending.
- Tax Litigation: Keysight is litigating a $107M tax refund claim regarding GILTI regulations. While a partial summary judgment was granted in July 2026, the U.S. government may appeal, creating uncertainty around the recorded tax benefit.
- Supply Chain: Extended lead times and manufacturing capacity constraints could lead to order cancellations or excess inventory if demand softens.
Investor Verification Checklist
- Tax Benefit Sustainability: Verify the finality of the $97M audit settlement benefit and the outcome of the ongoing GILTI tax refund litigation ($107M claim).
- Tariff Refund Realization: Monitor the actual collection of the $64M outstanding IEEPA tariff refund receivable and potential delays in government processing.
- Acquisition Integration: Assess the revenue contribution and margin accretion from the Spirent, Synopsys, and Ansys acquisitions against integration costs.
- Order Backlog Conversion: Review the conversion rate of the strong order backlog ($5.8B for 9M) into revenue, considering potential cancellations due to extended lead times.
- Centripetal Litigation: Track the status of remaining appeals in the Centripetal Networks patent disputes to assess potential future liabilities or injunctions.
