Keysight stock (NYSE: KEYS) enters fiscal third-quarter earnings on Tuesday, August 18. The prior quarter was the best in company history. Records fell across orders, revenue, earnings, and free cash flow.
Yet a courtroom helped. A Supreme Court tariff ruling delivered a $100 million accounting benefit. That windfall lifted reported gross margin toward 72.3%. It will not repeat next quarter.
So this analysis splits the real business from the one-time boost. Keysight stock has re-rated hard on AI demand. The coming report shows which story investors actually bought. It also tests how much of the record quarter was truly durable.
What Tuesday’s Report Should Show
Start with guidance, because management sets the bar. The numbers leave little slack.
Keysight guided third-quarter revenue to $1.730 billion to $1.750 billion. That implies roughly 29% growth at the midpoint. Non-GAAP earnings should land at $2.43 to $2.49 per share. That marks about 43% growth at the midpoint. The company assumes roughly 173 million diluted shares.
Corporate Earnings Guidance: Keysight Technologies Fiscal Q3 2026 Projections (2026 Reference)
| Keysight Fiscal Q3 2026 Metric | Guidance Range & Projections |
|---|---|
| Revenue Guidance Range | $1.730 billion to $1.750 billion |
| Implied Top-Line Growth | ~29% growth at midpoint |
| Non-GAAP EPS Guidance Range | $2.43 to $2.49 per share |
| Implied Earnings Growth | ~43% EPS growth at midpoint |
| Diluted Share Count Assumption | ~173 million diluted shares |
| Official Earnings Report Date | August 18, 2026 (after market close) |
Keysight has beaten consensus in three of its last four quarters. Last quarter’s surprise topped 23%. Still, one caution stands out. Zacks’ model does not currently predict a beat. Its Earnings ESP reads 0.00%. That signal implies limited upside versus consensus. It does not predict an outright miss. Investors should still weigh guidance against the AI backdrop.
Investment Takeaway: Consensus sits inside guidance, not above it. That setup looks calmer than many AI-linked names carry into earnings. The real variable is the margin once the tariff benefit fades. Keysight stock will move on that, not the headline.
The Record Quarter, Read Carefully
The second quarter was genuinely exceptional. But it needs one adjustment to read correctly.
Orders reached $2.051 billion, up 56% year over year. Revenue rose 31% to $1.717 billion. Non-GAAP earnings jumped 69% to $2.87, beating a $2.32 consensus. Free cash flow hit $472 million. Cash ended the quarter at $2.43 billion.
Here is the part where most coverage dropped. Acquisitions added 700 basis points to order growth. Currency added another 100. So core orders grew 48%, not 56%. Core revenue grew 24%, not 31%. That is still excellent. It is simply a different number.
Corporate Financial Growth: Reported vs. Core Growth Metrics Breakdown (2026 Reference)
| Financial Metric | Reported Growth Rate | Core Organic Growth Rate |
|---|---|---|
| New Incoming Orders | Up 56% reported | Up 48% core growth |
| Total Realized Revenue | Up 31% reported | Up 24% core growth |
Orders also outran revenue by a wide margin. That gap points to a healthy book-to-bill ratio. It suggests revenue can keep climbing into fiscal 2027.
Segment performance was broad. Communications Solutions Group’s revenue grew 35%. Electronic Industrial Solutions Group’s revenue rose 24% to $486 million. Chief executive Satish Dhanasekaran called it the strongest quarter in company history.
Investment Takeaway: Core growth near 24% in revenue is the honest baseline. Acquisitions contribute meaningfully, which is fine. Still, investors should track organic momentum on its own.
🔗Organic Growth
The Tariff Windfall That Lifted the Margin
Here is the accounting detail that reframes the quarter.
In February 2026, the Supreme Court ruled on certain tariffs. It found that the emergency duties were not authorized by law. Later rulings then directed Customs and Border Protection to build refund processes.
For the quarter ended April 30, Keysight booked a $100 million receivable. It represents recovered tariffs plus statutory interest. The offsets landed across three separate lines.
Regulatory Accounting: Tariff Recovery Breakdown & Financial Statement Impact (2026 Reference)
| Tariff Accounting Item | Monetary Amount | Financial Statement Destination & Impact |
|---|---|---|
| Total Receivable Recorded | $100 million | Classified under other current assets pending final resolution |
| Cost of Sales Offset | $93 million | Directly reduces cost of goods sold, lifting reported gross margin |
| Operating Expenses Offset | $4 million | Reduces SG&A expenditure line items |
| Interest Income Offset | $3 million | Accrued into other financial income statements |
| Surcharge Refund Liability | $40 million | Recognized as a liability that directly reduces recognized revenue |
The effect shows up in the margin line. Reported gross margin reached 72.3%. Management said the durable figure sits in the mid-67% range. That level matches the software-driven expansion already underway. Meanwhile, a $40 million liability cut reported revenue. So the tariff episode cut both ways in one quarter.
Next quarter removes the $93 million cost-of-sales offset. Modeling should therefore start from the mid-67% base. That single change reshapes the whole margin comparison.
Investment Takeaway: The core margin story is real, driven by software mix. But anyone anchoring on 72.3% will be disappointed. Roughly five of those points came from a court decision.
🔗One-Time Items
Where Keysight Stock’s Growth Actually Comes From
Three demand pools drive the acceleration. They are unusually well diversified.
Artificial intelligence infrastructure leads. Keysight’s AI-related business topped $500 million in the first half. That already exceeds all AI revenue from the prior fiscal year. The driver is physical, not hype. Faster data center interconnects need new validation equipment. Keysight sells the instruments that certify those links. Each speed upgrade then triggers a fresh testing cycle. That makes the AI demand recurring, not one-off.
Commercial Communications revenue grew 40% to $858 million. High-speed optical network testing supports that line. The Aerospace, Defense, and Government segment added $373 million, up 24%. Governments keep funding radar, satellite, and electronic warfare validation. Defense budgets rarely track the commercial cycle. That steadiness offsets swings in chip and telecom demand.
Demand Pools & Revenue Growth: Segment Performance Breakdown (2026 Reference)
| Demand Pool Category | Recent Financial Figure | Growth & Performance Metric |
|---|---|---|
| AI-Related Business | Over $500 million (first half) | Exceeded total of prior fiscal year |
| Commercial Communications | $858 million | Up 40% year-over-year |
| Aerospace, Defense & Government | $373 million | Up 24% year-over-year |
| Electronic Industrial Solutions | $486 million | Up 24% year-over-year |
The strategic edge is simple. Keysight sells to whoever wins. It need not pick between chip architectures, network standards, or defense primes. All of them must test their designs first. That is a pick-and-shovel position on several technology races at once.
Investment Takeaway: AI test revenue more than doubled year over year. Defense growth stays insulated from commercial cycles. Together, they give Keysight two engines that rarely slow at the same time.
The Software Transition
The most important change is also the least visible.
Software and services now generate roughly 36% to 39% of sales. Annual recurring revenue approaches 30% of the mix. That shift carries gross margin toward the mid-67% level. Software simply earns better economics than instruments. Recurring contracts also smooth revenue across cycles. They soften the swings that hit pure hardware vendors.
Management is guided to more than $100 million in cost synergies. About 80% should reach run-rate by fiscal year-end. Acquisitions should add roughly $375 million in fiscal 2026 revenue. Capital expenditure guidance rose to $200 million. Chief financial officer Neil Dougherty reported no material supply chain issues. He also called memory cost inflation immaterial to the cost of goods.
Investment Takeaway: Recurring revenue near 30% is the quiet reason margins hold. It also supports the Keysight stock multiple, above that of a pure instrument maker.
Quantum, 6G, and the Technology Position
Research spending funds a position in markets for years from scale.
In quantum, QuantumPro software speeds superconducting qubit design. It blends electromagnetic simulation with automated circuit extraction. Pre-silicon side-channel tools flag hardware weaknesses early. They target post-quantum cryptographic threats before silicon ships.
🔗Recurring Revenue
In 6G, Keysight works on sub-terahertz frequencies. It also targets the 7 GHz to 24 GHz bands that regulators now weigh. Integrated sensing would let networks read physical environments.
Recent moves follow the same pattern. Keysight certified its design software for Intel Foundry processes. The European Space Agency picked it with Satellio for a 5G non-terrestrial framework. It also launched a 4x100GE cybersecurity test platform. Research and development runs near 17.5% of revenue. That spending rarely pays off right away. It instead builds option value for the next decade.
Investment Takeaway: Quantum and 6G add little revenue today. But they place Keysight inside standards bodies early. That position historically converts into instrument sales as markets commercialize.

Keysight Stock Valuation and the Bear Case
The stock has re-rated sharply. That is where the risk now sits.
Keysight stock carries a market capitalization near $56 billion. Shares trade near 32.5 times forward fiscal 2026 earnings. Analyst sentiment runs strongly positive. Thirteen analysts cover the stock. Eleven rate it a Strong Buy and two a Hold. The average target sits near $392. The range spans roughly $387 to $420.
Valuation Multiples & Market Sentiment: Comprehensive Metrics Breakdown (2026 Reference)
| Valuation Marker & Financial Metric | Current Market Figure & Reading |
|---|---|
| Market Capitalization | ~$56 billion total market cap |
| Forward P/E Ratio (FY2026) | ~32.5x prospective earnings multiple |
| Average Analyst Price Target | ~$392 average consensus target |
| Analyst Target Price Range | ~$387 to $420 per share spread |
| Wall Street Analyst Split | 11 Strong Buy, 2 Hold recommendations |
| Recurring Revenue Mix | ~30% recurring revenue stream |
The bull case is straightforward. Keysight compounds revenue in the high-20s. Software mix keeps expanding. Free cash flow keeps setting records. Cash stands at $2.43 billion. The company sells into AI, defense, semiconductors, and automotive at once.
The bear case is arithmetic. Core growth of 24% trails the 31% headline. Roughly five margin points came from a court ruling. Acquisitions add $375 million of revenue and flatter comparisons. Those comparisons then harden next year. And 11 of 13 analysts already rate it a Strong Buy. That leaves little room for a positive surprise. At 32.5 times forward earnings, execution must stay flawless. Any stumble would pressure Keysight stock quickly.
Investment Takeaway: Keysight stock is a high-quality compounder priced for execution. The next two quarters will test whether margins survive without the tariff gain.
The Risks That Matter
Most risks here trace to one theme. The headline numbers flatter the underlying business.
Margins normalize first. Reported gross margin of 72.3% held about five one-time points. Those points do not recur. Reported growth also overstates the core. Acquisitions and currency added 800 basis points to order growth. So organic momentum runs below the headline.
Comparisons then get harder. Record first-half results set demanding hurdles through fiscal 2027. Positioning adds pressure too. With 11 of 13 analysts at Strong Buy, expectations already sit high.
Several risks also sit outside the numbers. AI capital spending must continue at pace. Over $500 million of first-half revenue depends on data center buildouts. Integration carries execution risk as well. Delivering $100 million in synergies across acquisitions is not automatic. The tariff receivable is also not cash yet. Customs and Border Protection still needs to finish its refund process. Finally, cyclicality lingers. Test and measurement has always followed chip and telecom capital cycles.
Risk Assessment: Comprehensive Operational & Structural Risk Factors (2026 Reference)
| Identified Risk Vector | Strategic Significance & Diagnostic Implication |
|---|---|
| Margin Normalization | Reported 72.3% gross margin held approximately five one-time tariff points that do not recur going forward. |
| Reported Versus Core | Acquisitions and currency fluctuations added 800 basis points to order growth, potentially overstating true organic momentum. |
| Comparison Difficulty | Record first-half operating results create exceptionally demanding year-over-year comparisons through fiscal 2027. |
| Consensus Positioning | 11 of 13 covering analysts rating the stock at Strong Buy leaves little room for unexpected positive earnings surprises. |
| AI Capital Spending | Over $500 million of first-half revenue relies heavily on continued hyperscale data center infrastructure buildouts. |
| Integration Execution | Delivering $100 million in projected operational synergies across multiple corporate deals carries real execution risk. |
| Tariff Reversal Risk | The $100 million receivable asset depends on complex government refund processes that are still being built out. |
| Cyclicality Exposure | Test and measurement equipment has historically followed volatile semiconductor and telecom capital expenditure cycles. |
A Strong Compounder at a Full Price
Keysight holds an enviable position. Every AI cluster, 6G prototype, defense radar, and quantum chip needs validation. Keysight sells the instruments and software that validate them. Its second quarter set records across every headline line. Its AI business more than doubled. Management then raised full-year expectations.
So the verdict rests on one question. Can the business hold mid-67% margins and high-20s growth? That answer arrives once the tariff gains and acquisitions wash out. Both effects should fade over the next two prints.
Watch four markers on August 18. First, whether revenue clears the upper half of guidance. Second, what gross margin prints without a tariff offset? Third, whether core order growth holds near 48%. Fourth, what do management signals indicate about fiscal 2027?
The demand is real and broad. But Keysight stock now prices in near-perfect execution. The headline numbers just need reading twice.
