Pre-earnings preview · long-only PM · Nasdaq: TTMI

Great business momentum; the stock still needs a clean forward guide.

TTM Technologies reports Q2 2026 after the close. AI data-center PCB complexity and defense demand are real; the tactical problem is a consensus bar already above the company’s EPS guide and a valuation that leaves little tolerance for a merely in-line Q3.

Portfolio action

HOLD the core; do not exit before earnings.

For a normal-sized long-only position, the evidence supports holding, not a wholesale sale. Trim only if TTMI has become an oversized active weight after its 207% one-year rise. Do not add incremental event risk until Q3 guidance confirms that data-center growth and Penang yield gains can outrun the higher estimate bar.

What the stock likely requires

  1. Revenue close to or above $970m. The $950m guide midpoint is no longer the market bar.
  2. Data center at ~42% mix with quality. The market needs evidence that growth comes from complexity and mix, not only capacity-consuming volume. Management said high-layer-count boards can carry 4×–8× ASPs and that growth is mostly complexity/ASP.
  3. Q3 guide that meets a steep run-rate. Fiscal.ai consensus is about $1.053bn and $1.11 non-GAAP EPS. This is the pivotal reaction driver.
  4. Penang yield and margin proof. Q1 commentary put a key customer yield near 70%–80%, up from above 40%, and targeted breakeven by Q4 or earlier.
  5. Bookings that sustain the story. Overall Q1 book-to-bill was 1.41, commercial 1.65, A&D 1.10; 90-day backlog was $787m.

What is priced in

Market data At $134.86, TTMI has risen about 207% over one year, though it remains roughly 40% below its 52-week high of $223.83. Fiscal.ai shows about 30.2× NTM P/E and 20.0× NTM EV/EBITDA.

PM judgment The drawdown reduces but does not remove event risk. The current valuation still discounts a structural earnings step-up, not just a one-quarter beat. Therefore, a good print with an in-line guide can fade.

Missing No event-isolating options-implied move, reliable positioning data, or sourced whisper was available. This is a fundamentals-and-valuation action framework, not a trade-ready volatility call.

Operating proof points

AI / data-center PCBs

  • Q1 data center & networking was 36% of revenue and grew 61% YoY; Q2 mix guide is 42%.
  • Management described boards up to 80, 100 and 140 layers, with ASP uplift driven by complexity and material science.
  • About ten major customers participate in the segment; one was a 10% customer in Q1.
  • Investor Day framed TTMI as XPU-agnostic across AI servers, switches, backplanes and midplanes.

Aerospace & defense

  • Q1 was 40% of revenue, +11% YoY; program backlog was $1.6bn and A&D book-to-bill 1.10.
  • New Syracuse Ultra-HDI capacity opened June 22 after a $130m investment, including $30m of U.S. government support.
  • The facility targets radar, missile defense, space sensors and autonomous systems, but ramp timing—not the ribbon-cutting—is the earnings issue.
  • TTMI disclosed Q1 bookings tied to LTAMDS, AN/APS-153, ballistic-missile radar and an initial Iron Dome program.

Major developments since Q1

European acquisitions

TTMI agreed to acquire Swiss Technology Group and ILFA for cash, adding European PCB and medical/A&D capabilities. Management expects modest immediate accretion and a Q3 2026 close, subject to approvals.

Call issue: price, funding, purchase accounting and integration cadence remain undisclosed.

Syracuse capacity open

The 215,000-sq.-ft. Ultra-HDI facility opened June 22. It can create up to 400 jobs and is a strategic domestic defense asset.

Call issue: qualification, utilization and time to revenue/margin.

Capital and index changes

TTMI entered the Russell 1000 effective June 26 and in June announced a $1.0bn revolver plus an upsized term loan. Q1 capex guidance was raised to $300–320m from $240–260m.

Call issue: free cash flow was negative $85m in Q1; financing flexibility does not eliminate execution risk.

Bull / base / bear reaction map

Execution clears the higher bar

Q2: revenue ≥$979m, non-GAAP EPS ≥$0.95, data-center mix ≥42%, margins expand.

Forward: Q3 revenue ≥$1.09bn and EPS ≥$1.15; Penang breakeven pulled forward; book-to-bill stays >1.

Action: Hold; add only after guidance confirms. Falsifier: upside is only working-capital or below-the-line driven.

Good print, demanding stock

Q2: revenue $950–979m, EPS $0.87–0.94, data-center mix around 42%.

Forward: Q3 near $1.05bn / $1.11; margin improvement gradual; capex stays high.

Action: Hold core; expect two-way reaction. Trim only an oversized position. Falsifier: Q3 guide slips below the current mean.

The forward ramp breaks

Q2: revenue <$950m or EPS <$0.87; data-center mix below 40%; weak bookings.

Forward: Q3 revenue <$1.00bn or EPS <$1.05; Penang losses persist; free cash burn widens.

Action: Trim immediately; exit if demand and utilization—not timing—drive the miss. Re-underwrite if acquisition/debt obscures organic cash generation.

EPS-quality watch

ItemWhy it mattersEvidence needed after print
GAAP vs non-GAAPTTMI excludes amortization, SBC, restructuring/M&A, some FX and tax adjustments; consensus here is the non-GAAP series.Bridge every adjustment and compare adjusted operating income and EBITDA, not headline EPS alone.
FX and other non-operating expenseQ1 included a $7m realized FX loss; Q2 guide assumed ~$6.9m realized FX/other expense.Separate recurring operating progress from currency and below-the-line volatility.
Tax rate and sharesQ2 EPS guide assumes 107.5m diluted shares and a 13%–17% tax rate.Check whether EPS beat is driven by tax/share count rather than gross profit.
Cash conversionQ1 FCF was negative $85m as capex and working capital funded growth.Capex cadence, deposits, inventory and receivable build; 2026 FCF outlook.

Questions that determine the position

  1. What is the Q3 revenue and non-GAAP EPS range?
    Listen for ≥$1.05bn / ≥$1.11 and whether growth is capacity-, mix- or price-led.
  2. Did data center reach 42% of Q2 revenue, and how much was complexity/ASP versus units?
    Breaks the thesis if the mix miss reflects weaker hyperscale demand rather than shipment timing.
  3. Where are Penang yields now, and when does the site reach breakeven?
    Listen for stable ≥70%–80% yields and Q4-or-earlier breakeven.
  4. What were Q2 commercial and A&D book-to-bill and 90-day/program backlog?
    A sub-1 commercial ratio after the Q1 surge would weaken forward visibility.
  1. What portion of the capex raise is pull-forward versus a higher total program?
    Listen for committed customer demand and explicit 2027 revenue capacity.
  2. What is the Syracuse qualification and revenue ramp?
    A ribbon cutting is not earnings; ask for customer qualifications, utilization and margin drag.
  3. What do STG and ILFA cost, how are they funded, and what is their 2026 contribution?
    Breaks the thesis if leverage or integration risk dilutes the organic AI/defense story.
  4. Can 2026 free cash flow remain positive after $300–320m capex?
    Listen for working-capital normalization and whether acquisition funding crowds out buybacks.

Decision discipline after the print

Add
Only after Q3 guidance clears the current mean, data-center mix/complexity is intact, and Penang margin proof is visible.
Hold / trim
Hold a normal core position through a base outcome. Trim if oversized or if Q3 guidance only matches despite a strong Q2.
Exit
Exit if management attributes a Q3 shortfall to structural demand, customer losses, failed qualifications, or sustained utilization/yield problems.

Sources and evidence posture

Material gaps: no clean event-isolating options implied move; no reliable whisper; no current short-interest/positioning source; no public Q2 segment or margin consensus. The report therefore recommends a conditional portfolio action, not a precise event trade.
