Is it the Right Time to Buy TTMI Stock at a P/S Multiple of 2.59X?

TTM Technologies trades at 2.59x forward 12-month sales, below the 3.74x industry average and 6.05x broader technology-sector average, despite management targeting 15%-20% annual revenue growth and a doubling of earnings from 2025 to 2027. AI data-center and networking revenue rose 91% year over year in Q2 2026 and is expected to more than double for full-year 2026, while aerospace and defense backlog increased to $1.7 billion and the qualified pipeline exceeds $7 billion. Consensus Q3 2026 EPS is $1.25, up 11.6% over 60 days and 86.6% year over year; full-year EPS estimates of $4.82 are up 17.9%, supporting the bullish valuation case after TTMI's 83.2% YTD share-price gain.

Analysis

TTMI’s apparent revenue-multiple discount is not directly comparable with VICR, OUST or NVT: those companies carry different gross-margin structures, recurring-content profiles and end-market cyclicality. The investable question is whether the AI mix can lift TTMI’s blended margin and cash conversion enough to warrant a durable multiple re-rating, rather than merely producing a high-growth revenue year. The key confirmation over the next 1-3 months is gross-margin progression through the N+M ramp; revenue growth with yield-related underabsorption would validate the discount rather than close it.

The more underappreciated risk is customer and program concentration. Advanced PCB ramps can create sharp quarterly upside, but qualification changes, hyperscaler platform transitions, or a single customer deferring builds can leave newly added capacity underutilized; this would hit EBITDA disproportionately. Defense backlog reduces cyclicality but does not eliminate timing risk, since restricted-program awards and appropriations convert unevenly, while the Syracuse ramp creates a multi-year execution and capital-intensity burden.

Consensus is likely extrapolating the most favorable phase of the AI buildout while treating booked defense work as equivalent to near-term revenue. After a major share-price advance and estimate revisions, the next upside requires either margins above ramp expectations or evidence that design wins extend beyond the initial N+M program. A miss in either gross margin or data-center mix could compress the multiple quickly even if full-year revenue remains intact; this is better framed as an earnings-execution trade than a simple value opportunity.

Key Decisions for Investors

• Initiate a starter long TTMI only ahead of the next earnings release if channel checks or management commentary indicate improving N+M yields; target a 6-12 month hold. Add only if gross margin expands sequentially while data-center revenue remains elevated. Thesis fails on margin contraction or a material reduction in AI-related shipment outlook.
• Use a paired expression: long TTMI / short VICR in equal beta-adjusted dollars for 3-6 months. TTMI offers more direct high-volume interconnect exposure, while VICR’s premium is more dependent on sustaining differentiated power-architecture margins; close if TTMI’s ramp margin misses or VICR reports accelerating hyperscaler design-win conversion.
• Do not use NVT or OUST as primary valuation comparables for a directional TTMI trade; their end-market exposures make the apparent relative discount potentially misleading. Monitor them instead as broad AI-infrastructure sentiment indicators.
• Set an earnings alert around three metrics: sequential gross margin, capital-expenditure/cash-conversion guidance, and customer concentration disclosures. A revenue beat without margin or free-cash-flow improvement is a trim signal, not a reason to add.
