KEYS · Q1 2026 Earnings

Keysight Technologies

Reported February 23, 2026

30-second summary

Q1 revenue grew 23.3% YoY to $1.60B and non-GAAP EPS of $2.17 cleared the top of the Q4-issued guide by $50–70M and $0.16–0.22 respectively, with orders of $1.645B implying a 1.03x book-to-bill. Management raised FY26 to "just above 20%" total revenue and earnings growth — a step-change from the Q4 framing of ≥7% organic + $375M M&A (~12–14% combined) — and guided Q2 revenue to $1.69–1.71B (+29–30% YoY off the $1.31B Q2 FY25 base). This is no longer the "recovery accelerating" narrative; it is management calling AI-driven concurrent technology waves the operating regime.

Guidance

Keysight raised FY2026 full-year guidance to ~20% revenue and earnings growth (from ~12–14% prior), driven by Q1 beat on both revenue (+4–5% above guide) and EPS (+$0.16–$0.22 above range), with strong momentum into Q2.

Guidance is issued for both next quarter and the full year. Both may appear below.

Management tone

Narrative arc: Q2 "gradual recovery, raise to midpoint" → Q3 "recovery ahead of plan, raise to top of range" → Q4 "FY26 at or above long-term targets, M&A on top" → Q1 "compounding momentum, FY26 just above 20%, concurrent technology waves."

Three quarters ago AI was framed as the wireline-specific tailwind that justified raising FY25 to the top of the 5–7% organic band. Two quarters ago it was quantified as "roughly half of wireline." This quarter Satish drops the segment qualifier entirely and reframes the entire growth regime: "concurrent parallel technology waves that are coming at pretty much an unprecedented rate…now are happening concurrently" and "we see this compounding momentum this year…all of these tailwinds…coming together." The word "compounding" is the tell — management is no longer modeling cyclical capex; they are modeling overlapping upgrade cycles (800G→1.6T→3.2T) that pull forward and stack.

Manufacturing was a future opportunity in Q4 and is now an in-period growth driver. Neil's prepared remarks called out that "both R&D and manufacturing grew year over year" in wireline — previously the framing was R&D-led with manufacturing as a long-tail mix shift. The implication: the AI wireline customer base has moved from design validation into volume manufacturing test, which is a higher-units, more recurring revenue profile and explains the +33% Commercial Communications print.

Customer concentration risk — the standing watch item from Q3 onward — was directly attacked rather than reassured. Management stated "we've doubled the number of customers that represented that demand" and explicitly noted "our top two were still non-AI customers." This is the first quarter where the broadening has a hard quantification (doubling) rather than directional language, and the disclosure that top two are non-AI defuses the hyperscaler-concentration tail risk that the bears have been pricing.

A&D's reframing completed this quarter. Q2/Q3 still characterized A&D as program-paced and budget-dependent; this quarter Satish stated "the increase in global defense spending represents a structural tailwind" with primes "investing more in organic R&D and also investing more in capacity ads." The +18% growth print (vs +8–9% in Q3/Q4) is the proof. A&D is no longer the lumpy diversifier; it is a second compounding leg.

The FY26 raise itself is the cleanest tone signal. The Q4 framing was deliberately conservative (≥7% organic, ≥10% EPS, M&A on top). One quarter later, management collapsed both into "just above 20%" total — and Neil acknowledged in the transcript "opportunity for upside if we can sustain the same level of momentum that we see in Q1 and Q2." That is management telling you the base case has room above it.

Recurring themes management leaned on this quarter:

AI infrastructure scaling driving concurrent R&D and manufacturing demandOptical interconnect and next-gen speed transitions (800G→1.6T→3.2T) creating overlapping upgrade cyclesCustomer base broadening from hyperscalers to silicon vendors, ecosystem, and emerging cloudsAerospace & defense as structural, not cyclical, tailwind supported by geopolitical spendingFull-stack solutions differentiation (physical layer + protocol emulation) sustaining competitive moatManufacturing intensity increasing in wireline, offsetting long-term R&D mix shift

Risks management surfaced:

Tariff impact from Supreme Court decision still being assessed; guidance does not contemplate impactMemory pricing pressures on DRAM and HBM supplies; company monitoring but not volume-constrainedIntegration execution risk on three acquisitions; synergy realization heavily weighted to late 2026Visibility cliff beyond two quarters out; base case assumes moderation in H2 despite strong pipelineAI software disruption risk to design tools and simulation workflows (though management downplayed)

Answers to last quarter's watch list

Q1 FY26 organic delivery. Q1 total revenue grew 23.3% YoY, well above the guide's implied ~19% and the Q4 framing's ≥7% organic + ~$375M M&A. With Q2 guided to ~30% YoY, the front-loaded vs. run-rate question is now answered in favor of run-rate — management raised FY26 to "just above 20%" total growth, implying the H1 strength is not a comparison artifact. Status: Resolved positively

Spirent/Optical Solutions integration economics. Synergy target was reaffirmed unchanged at >$100M run-rate, and segment operating margins held at 27% across both CSG and EISG this quarter. The acquisition-related revenue expectation also held at $375M. The integration cadence appears on track, but the heavy synergy realization is still flagged for later in FY26. Status: Continue monitoring

EISG re-acceleration or deceleration. EISG grew +15% YoY in Q1 with operating margin at 27% — a decisive re-acceleration from Q4's +9%. Semiconductor capex is compounding rather than normalizing. Status: Resolved positively

Wireline AI durability past Q1. Management quantified customer broadening ("doubled the number of customers" representing AI demand) and reframed wireline as concurrent R&D plus manufacturing growth, but did not put a dollar base or growth rate on the AI-tied wireline revenue specifically — the framing stays directional on dollar terms while becoming more concrete on customer count. Commercial Communications +33% is the indirect proof. Status: Resolved positively on durability; Continue monitoring on explicit AI-revenue disclosure.

6G design-phase revenue tagging. The Q1 commentary did not call out 6G as a distinct revenue contributor within Commercial Communications; the bull thesis has shifted to wireline AI as the dominant Commercial Communications driver, and 6G remains bundled. Status: Not resolved

What to watch into next quarter

Commercial Communications second derivative. Q1 at +33% is a step-change from the +9–13% sequence of the prior three quarters. Watch whether Q2 holds above +25% on a tougher comp ($716M in Q2 FY25 commercial comms is implied higher than Q1 FY25's base), or whether Q1 is the peak comp benefit. A Q2 print below +20% in Commercial Communications would suggest comp-driven inflation in the headline.

IEEPA tariff outcome and the carve-out's reversal. Management explicitly excluded any IEEPA Supreme Court ruling impact from the FY26 outlook. Watch whether the Q2 call quantifies either a tailwind (if duties are refunded/eliminated) or a discrete drag — and whether management refuses to re-fold this into the base case, which would itself be a tone signal.

EISG operating margin durability at 27%. EISG OM reached 27% this quarter, matching CSG. Watch whether this is a mix benefit from one quarter of strong semi capex or a structural step-up — a reversion to mid-20s would suggest the Q1 print included one-time leverage.

A&D second consecutive +15%+ print. +18% in Q1 vs +8–9% in Q3/Q4. Watch whether Q2 A&D growth holds above +15%, which would confirm the structural-tailwind reframing. A reversion to high-single-digits would mean the geopolitical-spending narrative is overstated.

FY26 raise math vs. H1 actuals. Q1 +23% and Q2 guided ~+30% imply H1 averaging ~+26%. "Just above 20%" for the full year therefore embeds H2 decelerating to ~14–16%. Watch whether management refuses to raise FY26 again on the Q2 call despite continued H1 outperformance — that would suggest H2 visibility is genuinely lower, validating the current ~20% framing as the ceiling. A Q2 raise would mean management has been deliberately conservative.
