## Key stats

- **Ticker:** KEYS
- **Market Cap:** ~$59B

## Moat

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.

### The Test-Standards Moat

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.

**Moat 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.

### Top competitors

- **Rohde & Schwarz:** RF and wireless test equipment.
- **Ralliant (RAL):** Tektronix oscilloscopes and test instruments.
- **Emerson Electric (EMR):** NI modular and automated test systems.

## Growth

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.

- **Revenue CAGR estimate:** 10-14%
- **Primary type:** TAM expansion
- **Margin trend:** expanding
- **Key risk (high):** 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.
- **Drivers:**
  - AI / Datacom Test — H1 AI-related $500-600M (≈ FY25 full year); wireline R&D and manufacturing both doubled; 800G/1.6T + system emulation (accelerating)
  - Aerospace & Defence — Q2 +24% YoY to $373M; broad Europe/Americas radar, EM spectrum, space demand (accelerating)
  - Commercial Communications — Q2 +40% YoY to $858M; AI wireline plus wireless/NTN/6G research (accelerating)
- **Score derivation:** 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

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.

| Multiple | Value | Note |
| --- | --- | --- |
| Forward P/E (FY26) | ~33× | EPS ~$10.20 Street; premium mid-cycle multiple |
| Forward P/E (FY27) | ~29× | EPS ~$11.90; still elevated vs historical mid-20s |
| Price / Sales (FY26) | ~8.5× | On Street ~$6.9B; software/ARR mix supports premium |
| PEG Ratio | ~2.8× | On ~12% blended CAGR; rich if FY26 spike proves peak |
| EV / EBITDA (NTM) | ~22-25× | Re-rated with AI cycle; vs Anritsu lower-teens, AMETEK high-teens |

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. _(as of August 10, 2026)_

## Price scenarios

### Bear — $220

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

### Base — $380

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

### Bull — $520

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
