CFO Michelle Turner (on her first Teradyne earnings call) provided critical color on 2026 patterns :

- 2026 expected: ~60% first half, 40% second half (the inverse)
- Backlog: Entering 2026 with "healthy backlog" providing better first-half visibility
Management cautioned against linear extrapolation: "The lumpiness of this new sales pattern... we could see things move between quarters and between years" .
Full Year 2025 Results
The $6B Target Earnings Model
Management unveiled a new "evergreen" target model—not tied to a specific year—illustrating what Teradyne looks like at scale :
The implied EPS of $9.50-$11.00 is roughly 2.5x current earnings .
CEO Greg Smith on the path to $6B: "We foresee a future where the ATE TAM will be $12-14 billion... In that market, Teradyne will deliver nearly 2x 2025's revenue and 2.5x the earnings per share" .
What Changed From Last Quarter?
The Q4 acceleration was dramatic. Revenue jumped 41% sequentially from Q3's $769M .
Segment Performance
Memory test revenue of $206M was a record quarter . All three segments delivered double-digit sequential growth .
The Compute Transformation
Teradyne's business mix has fundamentally shifted :
CEO Greg Smith: "This balance de-risks our target earnings model" .
2025 SoC TAM Breakdown (Q&A Detail)
Management provided specific 2025 TAM estimates :

Q&A Highlights
GPU Merchant Win Timeline
The anticipated merchant GPU qualification is on track but will be a second-half story:
"We're making great progress, and we expect to achieve production qualification... Our guidance for Q1 does not include any merchant GPU revenue. We see that as more of a factor in the second half of 2026" .
Management expects to start at single-digit share and work up to 30%-70% balanced share over several years .
VIP Market Share
Teradyne maintained approximately 50% market share in the VIP (Vertically Integrated Producer) compute market in 2025 . CEO Smith cautioned: "No share is safe. We are challenging for sockets that we don't have. We're being challenged for sockets that we do have" .
2026 TAM Outlook
Management declined to give a specific 2026 TAM number but provided a wide range: "If you wanted to put a big wide range around it, it'd be like 20%-40% growth for the year, but we don't know where in that range it would land" .
MultiLane Joint Venture
Teradyne announced a strategic joint venture with MultiLane, a leader in high-speed IO and data center interconnect test :
- Teradyne will be majority owner
- Expected to close in Q2 2026

- Two specifying customers (one mobile, one compute)
- One purchasing customer (does it all)
- Each roughly at the 10% threshold, not substantially higher

Robotics Update
Robotics remains the weak spot, but management sees a path forward:

-
5% of Q4 robotics revenue came from a large e-commerce customer
- E-commerce revenue expected to triple from 2025 to 2026
- Targeting breakeven in 2026, then positive contribution beyond
IST Business Expansion
The In-Socket Test (IST) business delivered >50% growth in 2025 with significant customer diversification:
- Won new mobile SLT customer (ramping 2025)
- Entered compute SLT market (two new customers)

- Dividends: $76M for FY 2025
- Cash position: $448M in cash and marketable securities
- Since 2015: Returned over $5.4B to shareholders
Key Risks to Watch
- Customer concentration: Three >10% customers in 2025
- Second half uncertainty: Management has limited visibility beyond Q2
- VIP share volatility: "No share is safe" in the competitive compute space
- Robotics execution: Must reach breakeven in 2026 for thesis to work
- Mobile TAM uncertainty: Questions about unit volume, product mix, and capital efficiency improvements
The Bottom Line
Teradyne delivered a statement quarter that validates its position as a primary beneficiary of AI infrastructure buildout. The combination of a 30% EPS beat, Q1 guidance 26% above consensus, and a new $6B target model with implied EPS of $9.50-$11.00 makes the bull case compelling.
The key debate is timing. Management introduced an "evergreen" model rather than tying targets to specific years because they can't predict how quickly the AI TAM grows. The current run rate suggests they could get there faster than skeptics expect—but as CEO Smith cautioned, "external conditions change things."
With AI now driving 60-70%+ of revenue and the compute transformation essentially complete, Teradyne has successfully de-risked from mobile dependence. The $6B target at 30-34% operating margins represents an entirely different company than the one investors knew even two years ago.
