Reported February 3, 2026

30-second summary

Q4 revenue of $1.083B obliterated the $920M–$1,000M guide by $83M at the high end, with non-GAAP EPS of $1.80 beating the $1.46 high end by 23% and non-GAAP operating margin of 29.0% running 350bps above the 25.5% midpoint. The bigger structural development is management's decision to retire date-anchored long-term guidance in favor of a TAM-indexed evergreen model — ~$6B revenue, 59–61% gross margin, and $9.50–$11 EPS at a $12–14B ATE TAM — explicitly because compute and memory demand has become too lumpy to time-box. Q1 FY2026 is guided to $1.15B–$1.25B (midpoint $1.20B, +11% QoQ), with 70%+ of revenue expected from AI applications.

Management tone

Narrative arc: Q2 "AI compute conviction firms" → Q3 "AI singular engine; Q4 step-up confirmed" → Q4 "AI dominates; long-term model goes evergreen because timing is unknowable"

Long-term guidance shifted from date-stamped to TAM-indexed — a deliberate retreat from time-boxed precision despite higher conviction on destination. Michelle Turner reframed: "Rather than anchoring our earnings model to a specific future year, as we've done historically, this year we are framing it around what our P&L looks like at an ATE TAM of $12 to $14 billion... This approach better reflects the inherent lumpiness in both compute and memory demand." The destination is now $9.50–$11 EPS at ~$6B revenue, but the timing went away. This is a confident company telling you the upside is bigger than it told you in October — but also telling you it can't predict which year it shows up. That tension is real.

AI exposure crossed from "majority" to "dominant operating model" with a concrete 70% number. Q2 framed AI as "the majority of H2 semi-test." Q3 elevated it to "the singular engine." This quarter Greg Smith quantified: "We expect that upwards of 70% of our revenue will be driven by AI applications in Q1 2026." That is no longer an AI-exposed semi-test company; that is an AI infrastructure company with a semi-test heritage. The portfolio composition shift (nearly 50% compute / balanced auto-industrial and mobile in 2025 vs. mobile-dominated in 2020–2021) is the strongest read on how thoroughly the business has reorganized around the AI thesis.

Robotics narrative converted from forward-looking to data-supported. Q2 and Q3 framed the 2026 robotics turnaround as a thesis with no quarterly proof points. This quarter the $89M Q4 print (up 19% QoQ, third consecutive quarter of growth) and the disclosed large e-commerce customer (>5% of Q4 robotics revenue, called out as a growth catalyst) provide the first concrete validation that the indirect-channel reset is yielding direct-customer wins. This was the most uncertain segment story; it now has its first data point.

Recurring themes management leaned on this quarter:

AI data center dominance (40-70% of revenue H2 2025 through Q1 2026)Compute TAM expansion and sustained share gains (targeting 50% share maintenance in VIP with incremental gains in merchant GPU)Revenue lumpiness normalization through customer diversification (moving from 2-3 hyperscaler dependency to 4-5 programs)Portfolio diversification reducing mobile dependency (50% compute, 25% auto/industrial, 25% mobile in 2025 vs 50% mobile in 2020-2021)Memory TAM shift from Flash to DRAM/HBM (90% of memory TAM by 2025)Physical AI robotics inflection (large e-commerce program tripling revenue 2025-2026)

Risks management surfaced:

VIP compute share volatility and non-linear ramp timing across competitors (noted as 'really noisy number' quarterly and yearly)Second-half 2026 visibility gap (TAM growth range 20-40% due to backlog uncertainty post-Q2)Mobile TAM recovery dependency on complexity, not units (cautious on capital efficiency improvements moderating demand)Merchant GPU production qualification timing and initial share dilution despite eventual 30%+ targetConcentration risk persistence (two specifying customers + one purchasing customer >10% each in 2025)

Answers to last quarter's watch list

Does Q4 land at or above the $960M midpoint, and what does the January 2026 update imply for Q1 and full-year 2026? Q4 came in at $1.083B — $123M above midpoint, $83M above the high end of guidance. Q1 FY2026 is guided to $1.20B midpoint with 70%+ AI revenue share and YoY growth across all businesses. Management called 2026 H1-loaded (60%/40%) and explicitly bullish, though full-year revenue was not point-estimated.

Resolved positively

Q4 non-GAAP operating margin delivery against the 25.5% midpoint. Q4 operating margin came in at 29.0%, 350bps above the midpoint. Q1 FY2026 is guided to 32% at midpoint — another 300bps step up.

Resolved positively

First disclosed merchant-GPU or new VIP customer revenue. Management explicitly stated they are "in play for a share of merchant GPU" and expect production qualification, with single-digit initial share growing toward a 30/70 split with the incumbent over a couple of years. No merchant-GPU revenue is in the Q1 guide; management sees it as an H2 2026 factor.

2028 model reweighting in January. The prior date-anchored model was retired in favor of an evergreen TAM-indexed model: ~$6B revenue at $12–14B ATE TAM, 59–61% gross margin, 30–34% operating margin, $9.50–$11 EPS. Status: Not resolved — the framework changed in ways that make a clean comparison to the prior target impossible.

Robotics — sequential trajectory above $75M and any named large-customer wins. Robotics delivered $89M, up 19% QoQ from $75M, the third consecutive quarter of growth. A large e-commerce customer drove >5% of Q4 robotics revenue and was called out as a growth catalyst. Customer not named, but this is the first concrete data point underwriting the 2026 turnaround.

Resolved positively

Memory TAM read-through into 2026. Memory TAM is now ~90% DRAM/HBM (with flash receding), and management characterized memory share as roughly 50% in VIP with continued HBM strength. Management expects low double-digit memory TAM growth in 2026.

What to watch into next quarter

Does Q1 land at or above the $1.20B midpoint, and does Q2 guidance show sequential growth or "digestion" after the current surge? Management framed the current strength as a multi-quarter surge that may be followed by a shorter digestion period. The first signal will be the Q2 guide on the Q1 call — flat or down would confirm the cyclical caveat; up would mean the AI ramp is even less time-bounded than management is willing to say.

Q1 operating margin delivery against the 32% midpoint. The Q4 print exceeded the prior midpoint by 350bps. Hitting 32% would validate the path toward the new 30–34% target model range and remove any doubt about operating leverage at scale.

H2 2026 visibility update. Management cited a wide range of ATE TAM growth scenarios due to backlog uncertainty in the second half. The Q1 call should narrow this; failure to do so would convert the "digestion" comment from a hedge into a base case.

First named merchant-GPU win or quantified revenue contribution. Management was explicit that no merchant-GPU revenue is in the Q1 guide and that the contribution is an H2 2026 event. Production qualification timing is the immediate gating event — once disclosed, the AI TAM thesis re-rates.

Robotics — does the large e-commerce customer momentum compound in Q1/Q2 prints? $89M needs to step up, not retrace. The disclosed customer is the strongest forward indicator robotics has produced in two years; quarterly proof points now matter.

Evergreen model framing — does management reintroduce any time anchor, or stay TAM-indexed? The retreat from date-stamped guidance was deliberate. If a year reappears in 2026, it signals confidence has tightened; if it doesn't, management is genuinely planning around an unknowable AI capex cycle shape.
