Analog Devices, Inc. (ADI) | The Buildout — AI Infrastructure

The Verdict

Analog Devices sells the analog content that surrounds compute — the chips that sense, convert, condition, control and power electronic systems. In AI data centers that means the optical control path inside transceivers, the power-conversion chain from the grid down to the processor package, and analog and mixed-signal content in automated test equipment. It does not sell compute or networking silicon. Management describes industrial as its most profitable business, with 15- to 20-year average product life cycles, and describes its edge as the highest average selling price in the industry and designs that it says are effectively not substituted once designed in.

Earnings Beat

Revenue was $4.02B in FY26 Q3, above the high end of guidance, up 11% sequentially and 40% year over year — the first $4B quarter in company history. Gross margin was 67.3% on an as-reported basis. The standout was data center, which reached 80% of communications and grew more than 100% year over year in both optical and power.

Management tone: Management's tone stayed confident and expansive, and shifted toward structure rather than the quarter: it escalated data center disclosure, raised the gross margin guide to ~74%, and re-based its view of analog industry growth from a prior 5% to 7% model to a possible double-digit compound. The supply and cost posture tightened at the same time. A quarter earlier management described general calmness among customers and lead times in good shape; on the Q3 call it said lead times have started to extend and that it is scenario-planning capacity. Management volunteered that the full extent of its announced price action is not captured in Q4, and repeated that there is little room for more margin accretion from utilization.

Management Guidance

For Q4 FY26 management guided revenue of $4.3B ±$100M, operating margin of 52% ±100bps, EPS of $3.86 ±$0.15, gross margin of ~74% (an increase of about 150 bps), non-operating expenses of ~$80M and a tax rate of 12% to 14%. Sequentially it guided industrial up high single digits, communications leading with data center up ~10%, consumer up high single digits and automotive up low single digits. Medium term, management says gross margin should hang in at the Q4 exit level 'as long as we maintain the revenue and mix that we expect.' It calls for a brisk growth year in 2027 without giving a number, targets OCS revenue roughly doubling this year with similar growth in 2027, expects the energy business to double by the end of the decade, and puts Maxim synergies at ~$700M in FY26 and $1B+ in 2027. FY26 capital expenditure is expected within 4% to 6% of revenue.

Trajectory

Revenue has risen in each of the last four reported quarters, from $3,076.1M in FY25 Q4 to $3,160.3M, then $3,623.5M, then $4,021.9M in FY26 Q3. EBITDA margin (operating income plus D&A as reported) went from 46.8% in FY25 Q4 to 52.4% in FY26 Q3, and gross margin on the same reported basis went from 63.1% to 67.3%. The drivers management names are broad industrial growth — all industrial businesses up year over year, led by automated test equipment, electronic test and measurement, aerospace and defense, and automation — an automotive cycle that moved from +2% to +16% year over year, and data center growing more than 100%. Pricing adds, in management's words, a couple of points to FY26 growth. The Q4 revenue guide implies roughly 7% sequential growth.

The Model

The model projects FY+1 revenue of $18,425.0M with EBITDA of $9,996M, a 54.25% margin, and FY+2 revenue of $21,202.0M with EBITDA of $11,608M, a 54.75% margin. The near term is anchored by the Q4 FY26 guidance and by data center growth management says is running above 100% year over year. FY+2 depends on whether data center sustains the runway management describes through at least 2030, whether the industrial recovery continues, and whether Empower's vertical power products turn design-ins into revenue.

Projections are the median of 4 independent model runs. The model’s revenue sits 14.1% above analyst consensus.

What Could Go Right — and Wrong

Looking Ahead

The next twelve months turn on whether the guided step-up holds and whether the AI-exposed part of the business keeps compounding. The Q4 FY26 print tests the revenue and ~74% gross margin guide along with the segment directions management gave; Q1 FY27 tests whether the announced price action lifts gross margin above the Q4 exit level against a seasonal shutdown. Beyond that, the packet's milestones are the Empower revenue ramp and Maxim synergies in 2027, the closing of the Alif acquisition with no timing given, and management's stated targets of roughly doubling OCS revenue and doubling the energy business by the end of the decade.

Annual Summary

The Company

Analog Devices designs, manufactures, tests and markets integrated circuits, software and subsystems built on high-performance analog, mixed-signal and digital signal processing technology. Its portfolio spans data converters, amplifiers, power management, radio-frequency ICs, edge processors and sensors. That analog content is what senses, converts, conditions, controls and powers electronic systems, which places ADI alongside the compute rather than inside it — the optical control path, the power-conversion chain and the test content that AI infrastructure needs.

ADI runs a hybrid manufacturing network of internal fabs plus external foundry and back-end partners. Owned wafer fabs are in Wilmington, Massachusetts; Limerick, Ireland; and Beaverton, Oregon, with probe, test and assembly concentrated in Cavite in the Philippines, Chonburi in Thailand, Penang in Malaysia and Chelmsford, Massachusetts. More than half of its wafer requirements come from third-party foundries, including TSMC, and fiscal 2026 capital expenditure is expected within 4% to 6% of revenue. Management says internal capacity has been more than doubled versus pre-COVID.

Business Segments

Competitive Landscape

Management frames ADI's position around price and stickiness rather than scale alone: the highest average selling price in the industry by its account, roughly 4 to 5 times the industry average, and designs it says are effectively not substituted once designed in. The competitive set is broad — several analog and power rivals name ADI in their own filings, and the relationship graph adds others competing in the same data center power and optical content. Management describes this cycle as different from the late-1990s buildout, citing far greater portfolio breadth and depth, more value per bit and per watt, and what it calls a gravity field of AI pulling everything with it.

Supply Chain

ADI sits upstream of AI data centers, supplying analog control, power-conversion and grid-to-chip content. More than half its wafers come from third-party foundries including TSMC, and its largest disclosed counterparty is a distributor at 24% of FY2025 revenue.
