KEYS — Keysight Technologies, Inc.

Market sentiment is predominantly bullish: fiscal Q3 2026 revenue of $1.846B and non-GAAP EPS of $3.07 beat consensus by a wide margin, and analysts carry a Buy rating (13 buy, 3 hold) with a consensus target of $416.63. The roughly 6-11% pullback after earnings came from AI-capex sustainability worries and supply-chain margin caution, not from any deterioration in results or guidance.

The revenue inflection is unmistakable and broad-based: sales were roughly flat-to-declining through 2024 ($1.31B in Oct-2023, $1.29B in Oct-2024), inflected higher in 2025 ($1.30B to $1.42B), then accelerated hard in FY2026: $1.60B, $1.72B, and $1.85B in the three reported quarters. YoY revenue growth jumped to roughly 23%, 31%, and 37% sequentially. Operating income more than doubled from $234M in Jul-2025 to $461M in Jul-2026, lifting operating margin from about 17.3% to 25.0% while gross margin stayed above 64%. This is a structural acceleration with operating leverage, not a one-quarter blip; quarterly free cash flow also improved to $403M versus $263M a year earlier.

Expensive versus its own history. As of 2026-08-27, the trailing P/E is 44.9x versus the 5-year average of 33.1x, and P/S is about 8.5x versus a 5-year average of 5.5x. The bull case rests on forward numbers: using the consensus forward EPS estimate of roughly $11.32, the forward P/E drops to about 28.8x, and the reported PEG of 0.35 reflects very strong expected growth. It is not a cheap stock, but the growth trajectory closes much of the valuation gap.

As of 2026-08-27, the stock is caught between trailing and forward reality: 44.9x trailing earnings looks expensive, but ~28.8x forward earnings is reasonable if the AI/wireline ramp and defense demand continue. The post-earnings pullback from around $375 to $325.82 has actually made the price more consistent with near-term earnings power, while the consensus target of $416.63 implies the Street expects this growth to persist. If hyperscaler capex keeps climbing and supply constraints ease, the current price is under-pricing the next two years; if AI spending pauses, the multiple is the downside risk.

Neutral-to-consolidating with a longer-term uptrend intact. As of 2026-08-27, RSI(14) was 48.1, price was 2.4% below its 20-day SMA and 1.4% below its 50-day SMA, but 14.6% above its 200-day SMA. That is a normal pullback within an uptrend rather than a breakdown, but there is no momentum-based entry signal yet; buyers would likely want to see a reclaim of the 50-day before adding aggressively.

• AI and hyperscaler capital spending on data centers, high-speed optical networking, and interconnect validation is the dominant tailwind.
• Defense and government budgets remain supportive, with electronic warfare, spectrum modernization, and satellite programs driving double-digit aerospace/defense growth.
• High valuation sensitivity to interest rates and tech-hardware volatility creates multiple-compression risk even on good news.
• Supply chain constraints, particularly around advanced components, could limit near-term margin leverage.
• Trade policy and tariff enforcement could disrupt global hardware supply chains and add cost uncertainty.

• Fiscal Q4 2026 earnings and full-year FY2026 report expected in late November 2026; management guided revenue of $1.9B-$2.0B and adjusted EPS of $3.34-$3.40.
• Continued hyperscaler AI infrastructure buildout, including optical upgrades from 800G to 3.2T architectures and AI-RAN/6G R&D spending.
• Analyst estimate revisions and price-target increases, with consensus already at $416.63 and recent average targets above $418.
• Easing supply chain constraints would improve operating leverage and push margins above current consensus.

• Valuation is rich versus own history; any growth disappointment or AI capex slowdown could hit the multiple hard.
• AI infrastructure spending is cyclical and concentrated among a few hyperscalers; a pause would directly hurt wireline test demand.
• Supply chain bottlenecks could cap gross and operating margin expansion despite strong revenue.
• Insider selling of roughly $31.3M over the trailing 12 months with zero insider buys is a caution flag.

Keysight is a high-quality franchise with accelerating revenue, expanding margins, strong free cash flow, and clear AI/defense tailwinds. The main issue is price: trailing valuation is rich, but forward earnings growth makes it more reasonable. For an investor comfortable with some multiple volatility, this is a strong business to own; the smarter entry is on pullbacks rather than chasing strength.

I applied a 35x forward P/E to the consensus forward EPS estimate of $11.32, a modest premium to Keysight's 5-year average P/E of 33.1x justified by accelerating AI-driven revenue growth and margin expansion, but below the Street's $416.63 consensus target to reflect the rich trailing valuation and cyclicality of AI capex. 35.0 x $11.32 = $396.24.
