Keysight Technologies, Inc. (KEYS) | The Buildout — AI Infrastructure

The Verdict

Keysight makes design and test solutions used across computing, communications, and electronics. Its instruments, software, and emulation systems validate chips, optical transceivers, switches, racks, and clusters before they ship at volume, placing the company in the validation layer of AI infrastructure. Customers use Keysight from pre-silicon design through component validation, system-level emulation, and high-value manufacturing.

Earnings Beat

Keysight reported fiscal Q3 2026 revenue of $1.846B, up 36% reported and 31% core, with gross margin of 65.9% on reported figures and operating margin of 33.2%. EPS was $3.07, up 79% year over year, and orders were $2.091B, up 56%, a second straight $2B+ quarter. Management said results exceeded the high end of its revenue and EPS guidance.

Management tone: On the Q3 call, demand language strengthened — records, all-time-high pipeline, demand 'far exceeding' supply — while supply language became more constrained: 'less flexible today' and 'governor of near-term revenue.' Management also volunteered that one-time tariff benefits flattered FY2026 profitability and would not repeat.

Management Guidance

Management guided Q4 FY2026 revenue of $1.930B–$1.950B and EPS of $3.34–$3.40, and FY2026 revenue growth of 32% with EPS growth of approximately 60% at the midpoint. It reaffirmed 'upper 60s percent' gross margin as sustainable and a 40% long-term incremental-margin framework, while saying it expects to outperform that framework in FY2027 adjusted for non-repeating tariffs. Cost synergies are now expected at 80%–90% of $100M on a run-rate basis exiting FY2026, with roughly $50M incremental into FY2027. Management said it would give Q1 FY2027 guidance at the Q4 report.

Trajectory

Revenue stepped from $1.600B in Q1 FY2026 to $1.717B in Q2 and $1.846B in Q3. EBITDA margin on reported figures rose from 17.9% to 28.5% to 30.7%. Management ties the move to AI infrastructure scaling, wireline orders more than doubling year over year, and record semiconductor test demand. The near-term ceiling is supply: management says supply chain is the governor of near-term revenue.

The Model

The model projects FY+1 revenue of $8,740M and EBITDA of $2,753M, a 31.5% margin. For FY+2 it projects revenue of $10,371M and EBITDA of $3,371M, a 32.5% margin. The near-term anchors are AI infrastructure demand, wireline orders above $2B per quarter, and the supply constraint as the main swing factor. The FY+2 step-up depends on supply flexibility arriving, the product refresh contributing, and 6G and defense activity building.

Projections are the median of 5 independent model runs. The model’s revenue sits 15.1% above analyst consensus.

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months, the key test is the Q4 FY2026 report expected in Nov 2026, when management is expected to report against $1.930B–$1.950B revenue and $3.34–$3.40 EPS and give Q1 FY2027 guidance. Investors watch whether supply eases, whether wireline stays above wireless, and whether the AI business is resized or redefined. 6G activity remains funded development ahead of the first standard targeted for March 2029.

Annual Summary

The Company

Keysight makes design and test solutions for computing, communications, and electronics. Its instruments, software, and emulation systems are used to design, characterize, validate, and production-test chips, optical transceivers, network gear, and data-center racks and clusters. Revenue is primarily from R&D applications, and customers are in over 100 countries across communications, aerospace/defense, automotive, energy, industrial, and semiconductor end markets.

The company reports in two segments, CSG and EISG. Manufacturing is centered in Penang, Malaysia, described in the 10-K as its largest facility for final assembly, tuning, calibration, and test, with significant U.S. manufacturing in California and Colorado and technology centers in Santa Rosa, Colorado Springs, and Boeblingen. Keysight says it is vertically integrated for a significant portion of its highly specialized chips and assemblies, and management says memory is a small portion of its bill of materials.

Business Segments

Competitive Landscape

Keysight competes across test and measurement against a broad set of named companies, including Rohde & Schwarz, Anritsu, Advantest, Teledyne, Viavi, Fortive/Tektronix, Teradyne, Ametek, Emerson/NI PXI, Ralliant, Cadence, Silvaco, Arista, NetScout, McGrath RentCorp, and RADCOM. The source material says several competitor filings name Keysight, and Keysight's own 10-K warns that custom parts are 'not readily available from alternate suppliers.' The evidence says Keysight's differentiation is strongest where portfolio breadth matters, but competitors are also inflecting.

Supply Chain

Keysight sits in the validation layer of the AI build-out, supplying test and measurement systems to chip, optical, networking, and hyperscaler customers. Supplier identities come mainly from an automation-sourced relationship map, not the 10-K, and no neighbor named Keysight.
