Combined average of Moat (AI Resilience), Growth, and Valuation scores.
Moat Score
Premium electronic test and measurement franchise built on the Hewlett-Packard / Agilent legacy, with deep technical IP in RF/microwave, optical, and digital test — irreplaceable in regulated and bleeding-edge electronics development. Q2 FY26's record AI/wireline bookings reinforce demand for the franchise without changing the competitive structure versus Anritsu or Rohde & Schwarz.
Keysight's moat is decades of accumulated test IP, calibration standards, and customer R&D embedment — not flashy, but exceptionally durable:
- Calibration and Standards Heritage: Keysight's signal-source and analyser calibration traceability — inherited from HP — is reference-standard across global telecom regulators, defence labs, and semiconductor fabs. Replacing Keysight in a calibration chain requires re-validating every measurement, an expensive multi-year exercise.
- Software Embedment in R&D Workflows: PathWave and KeysightCare software embed into customer R&D workflows for chip design, RF/wireless, optical, and EDA test. Designs validated on Keysight tools carry test scripts and reference suites that take years to re-author on competitor platforms. Software and services are ~36% of revenue and ARR ~27% of mix — the modern moat compounding on top of the hardware franchise.
- AI / Datacom and 6G Optionality: AI infrastructure (800G/1.6T optical, PCIe, Ethernet/UALink fabrics, system-level emulation) and early 6G/NTN research are the live test-equipment supercycle. H1 FY26 AI-related revenue of $500-600M already matched all of FY25; Anritsu and Rohde & Schwarz address subsets but only Keysight covers the full stack from physical layer through workload emulation.
Ten Moats Verdict
Keysight is a high-quality test-and-measurement franchise with deep regulatory + software embedment moats. AI is a net positive demand driver (test capex follows AI infra capex) and the moat is largely AI-resilient — the primary risk is cyclical digestion after the FY26 re-rating, not technological disruption.
Test engineer learning curve on PathWave and instrument workflows is meaningful — engineers train for years on Keysight platforms.
PathWave software platforms encode customer-specific test scripts, calibration sequences, and R&D workflow business logic that take years to migrate.
N/A.
Microwave/RF, optical, and high-speed digital test engineering talent is genuinely scarce; Keysight has the deepest bench inherited from HP/Agilent.
Hardware + PathWave + KeysightCare service bundle is the broadest in test; rivals address subsets but no one matches the full stack.
Calibration libraries and reference measurement databases accumulate over decades and feed standards-compliance — real but not data-flywheel-monetised.
NIST/UKAS/PTB calibration traceability and ITAR-controlled defence test products are real regulatory moats; replacing Keysight in regulated calibration chains takes years.
instrument vendor with no network effects.
Test instruments have 10-15 year service lives; once installed in a customer R&D lab, swap-out is multi-year.
PathWave is becoming the system of record for R&D test scripts and calibration data in many customer organisations.

Moat Score

Q2 FY26's record AI/wireline bookings reinforce demand for the franchise without changing the competitive structure versus Anritsu or Rohde & Schwarz.
Growth Score
Q2 FY26 set company records: revenue $1.72B (+31% reported / +35% ex-tariff), orders $2.05B (+56%), non-GAAP EPS $2.58 ex-tariff (+52%). CSG +35% (commercial communications +40%, aerospace & defence +24%); EISG +24%. Management raised FY26 revenue growth to the high-20s%; Q3 guided $1.73-1.75B (~29% YoY) and $2.43-2.49 EPS. AI/wireline is the swing factor — early innings per management, with Spirent/acquisition contribution ~$375M in FY26.
Valuation Score
At ~$341 KEYS trades at ~33× FY26 EPS (~$10.20) and ~29× FY27 (~$11.90) — a full re-rating from the mid-20s trough multiple after the AI/test recovery. Price sits between bear ($220) and base ($380), modestly below Street's ~$372 consensus target; quality + AI exposure is priced, so risk-reward hinges on whether high-20s growth normalises without a hard digestion air pocket.

Growth Analysis
Growth Drivers
Key Risk
If AI infrastructure capex digestion arrives in 2027 (as with the 2022-23 5G cycle), the AI/datacom segment growth halves and the ~29–34× earnings multiple compresses 25-30% — Keysight's cyclicality is real even after the FY26 re-rating.
Score Derivation
75.7 base + 4.0 trajectory + 4 margin − 10 risk = 74
Base ~76 (12% midpoint of 10-14%) + 4 trajectory (AI/wireline, commercial communications, and aerospace & defence all accelerating on Q2 prints) + 4 margin (ex-tariff op. margin 30.4%, expanding) − 10 high cyclical digestion risk = 74

Valuation Multiples
| Forward P/E (FY26) | ~33× |
| Forward P/E (FY27) | ~29× |
| Price / Sales (FY26) | ~8.5× |
| PEG Ratio | ~2.8× |
| EV / EBITDA (NTM) | ~22-25× |
Valuation has re-rated with the AI/test recovery; fair only if high-20s growth decays orderly into the teens — a 2027 digestion is the clear downside case.

Where We Are vs Targets
Loading live price…
AI capex digestion in 2027 compresses datacom growth, commercial comms decelerates, and the multiple compresses toward ~20× on a lower earnings base — roughly 35% below spot.
- AI/datacom test growth slows below 10% in 2027 on infrastructure capex moderation
- Commercial communications fails to hold mid-teens as 6G research stays early and wireline digestion hits
- Spirent/acquisition synergies disappoint; multiple de-rates from the high-20s/low-30s zone
FY26 high-20s growth delivers, AI/datacom stays structurally elevated into FY27 at ~10-15%, margins hold ~30%, and the stock earns into ~28-30× on FY27/FY28 EPS near Street's ~$372 consensus.
- AI/datacom sustains double-digit growth through 2027 after the FY26 spike normalises
- Operating margin holds near 30% on mix + acquisition cost synergies (>$100M targeted)
- Aerospace & defence remains a durable mid-teens contributor amidst geopolitical demand
AI test supercycle persists through 2028, 6G/NTN research begins meaningful commercial spend, and the multiple holds ~32-35× on a larger mid-teens growth earnings base.
- AI/datacom test sustains 20%+ growth through 2028 across optical, SerDes, and system emulation
- 6G research and NTN/LEO validation drive commercial communications reacceleration beyond wireline AI
- Defence and semiconductor test keep compounding; Street revises FY28 EPS through the mid-teens
