Hook & thesis
TTM Technologies (TTMI) just delivered a Q3 that reads like a proof point for the AI infrastructure trade: revenue of $1.2B (up 59.9% YoY) and non-GAAP EPS of $1.46 (up 117.9% YoY). Management followed that with 2027 guidance of $6.5B-$6.75B in revenue and EPS of $8.10-$8.90 and announced a $400M capacity expansion for data-center capacity growth.
Yet the stock has been punished recently on concerns around extended component lead times, a data-center miss in Q3 execution, and incremental interest expense tied to acquisitions. That pullback leaves TTMI trading at roughly $89.53 today - effectively near 11x the midpoint of FY27 EPS guidance. For investors willing to back secular AI demand and the company’s execution on capacity expansion, that valuation is compelling.
What TTMI does and why you should care
TTM is a high-volume manufacturer of printed circuit boards (PCBs), backplane assemblies and RF components with exposure across three segments: Aerospace & Defense (A&D), Commercial (automotive, medical, industrial, networking and data center), and Radio Frequency & Specialty components. The key fundamental driver right now is AI-related data-center demand, which requires high-specification PCBs and backplanes in volume.
The market should care because the data-center and networking end market is moving from incremental upgrades to a multi-year, capacity-led buildout to support generative AI and hyperscale deployments. TTM sits squarely in that supply chain - its Q3 update showed Data Center and Networking sales up 115% YoY - and management is putting real capital behind the opportunity with a planned $400M capacity expansion for 2028.
Recent financials and the case in numbers
| Metric | Result / Note |
|---|---|
| Q3 Revenue (reported 10/23/2026) | $1.20B - +59.9% YoY |
| Q3 non-GAAP EPS (reported 10/23/2026) | $1.46 - +117.9% YoY |
| 2027 Guidance (management) | $6.50B - $6.75B revenue; EPS $8.10 - $8.90 |
| Adjusted EBITDA margin (Q3) | ~20.1% |
| Market cap | $9.43B |
| Enterprise value | $10.03B |
| Current price (today) | $89.53 |
| 52-week range | $55.44 - $223.83 |
Using management’s EPS guidance, the midpoint is $8.50. At today’s price of $89.53 that implies a forward multiple of roughly 10.5x - call it 11x FY27 for simplicity. That’s materially cheaper than where many AI-related suppliers traded at the height of the cycle and reasonable relative to a company with double-digit operating leverage and a targeted margin profile north of 20% at scale.
Valuation framing
Look at it two ways. First, absolute: a market cap near $9.4B and enterprise value near $10.0B for a company guiding to $6.5B-$6.75B in revenue and $8.10-$8.90 in EPS is a modest multiple if you buy the thesis that AI data-center demand remains structural and that TTM can ramp capacity without crippling margin dilution. Second, relative: TTMI’s forward P/E near 11x on guidance is far below the 20-30x multiple many high-growth infrastructure suppliers asked for earlier in the cycle when investors priced in near-perfect execution and no near-term supply friction.
Note: EV/EBITDA sits near ~20.5x on the most recent trailing figures, reflecting that some leverage is already priced into the business on an enterprise basis. The mismatch between a sub-12x forward P/E and a higher EV/EBITDA suggests the market is factoring in balance-sheet and capex swings as TTMI invests to scale capacity.
Catalysts to drive the trade
- Capacity expansion execution - management’s $400M plan for 2028. If TTMI executes this capex program smoothly, revenue should scale materially into FY28 as data-center wins convert to shipments.
- Data-center order cadence - continued high growth (Q3 data-center sales +115% YoY) converting into backlog-to-revenue conversion over the next 6-12 months.
- Defense backlog monetization - management cited a roughly $2B defense backlog that provides downside revenue stability while commercial builds ramp.
- Margin expansion - if adjusted EBITDA stabilizes near 20% as volumes scale, free-cash-flow conversion will improve and de-risk the current elevated EV/EBITDA.
- Supply-chain normalization - shorter lead times and fewer misses would materially re-rate the stock as execution risk falls.
Trade plan - actionable entry, targets and time horizon
Trade stance: Long TTMI.
| Entry | Target | Stop | Horizon |
|---|---|---|---|
| $89.53 | $93.50 | $79.00 | Long term (180 trading days) |
Rationale: Entry at $89.53 captures the post-earnings weakness driven by temporary execution and interest expense concerns. The target of $93.50 reflects a conservative 11x multiple on a $8.50 FY27 midpoint EPS - reasonable for a company with explicit AI exposure but not yet fully de-risked. The $79.00 stop limits downside to a level below the recent consolidation zone and gives the trade room to absorb short-term noise while protecting capital.
The recommended horizon is long term (180 trading days) because capacity expansion, backlog conversion, and supply-chain normalization take months to play out. Expect the bulk of newsflow - capacity build plans, order conversions and margin cadence - to unfold over several quarters; this is not a short-term trade on event arbitrage.
Key technical and market context
Technically, momentum indicators show room to rebound: RSI sits near 40 and the 10-day SMA is about $89.72, while price remains well below the 50-day/21-day EMAs - evidence of a short-term pullback into a longer-term uptrend. Short interest has increased recently (settlement 10/15 short interest ~4.97M; days to cover ~1.69), which can amplify rebounds once execution risk appears to be fading.
Risks and counterarguments
- Execution risk on capacity build: The $400M capacity program is large and requires timely equipment delivery, hiring and ramp discipline. Delays would push out revenue and likely pressure margins and cash flow.
- Supply-chain lead-time risk: Management disclosed component lead times hitting 24 weeks, which caused a 10% miss in the data-center division. If lead times persist, order fulfillment and customer relationships could suffer.
- Rising interest expense and leverage: Recent acquisitions increased quarterly interest by ~$20M, and debt-to-equity sits near 0.5. If higher rates persist or acquisitions underperform, the balance sheet could compress EBITDA conversion.
- Demand concentration and cyclicality: Data-center volumes are lumpy and dependent on hyperscalers; a pause or postponement in hyperscaler capex could quickly reduce TTMI’s growth trajectory.
- Valuation complacency if guidance slips: The trade depends on FY27 guidance holding. If management lowers EPS or revenue guidance materially, the apparent 11x forward multiple would look expensive and lead to further downside.
Counterargument: Critics will point to the 52-week high of $223.83 and argue the stock has already run and the pullback is a sign that the market is recalibrating to a lower structural TAM. They will also emphasize the elevated EV/EBITDA and say TTMI still deserves a multiple discount until capacity spend proves accretive. Those are fair points - the trade assumes management can execute expansion with no major margin dilution. If they cannot, the multiple compression case plays out quickly.
What would change my mind
I would reduce conviction or exit the long if any of the following happen: (1) management cuts FY27 guidance or materially revises the $8.10-$8.90 EPS range downward, (2) the $400M capacity expansion is delayed beyond planned timelines or faces permitting/equipment bottlenecks, (3) supply-chain lead times extend further and produce a multi-quarter hit to data-center shipments, or (4) interest expense increases materially beyond the recent ~$20M quarterly increment without commensurate revenue upside.
Conclusion
TTM Technologies is a quintessential “AI infrastructure on a dip” trade: it has real end-market exposure to secular AI demand, a credible margin profile (adjusted EBITDA near 20% in Q3), and a concrete capacity plan to capture incremental market share. The recent sell-off centers on execution and financing noise that, while real, appear addressable and likely temporary if management executes the 2028 capex program and backlog converts as expected.
Buying at $89.53 with a stop at $79.00 and a conservative 11x FY27 target of $93.50 gives a disciplined entry into a name where the upside from successful execution appears to exceed the downside from short-term operational friction. Keep the trade horizon to long term (180 trading days) to allow capacity and supply normalization to play out.
