TTM Technologies (TTMI) Q4 2025 earnings review
AI Supercycle Drives Record EPS, Masking Cash Flow Dip
TTM Technologies closed FY25 with a significant beat, driven entirely by the Generative AI infrastructure boom. Q4 revenue grew 19% YoY to $774.3M, while Non-GAAP EPS hit a quarterly record of $0.70 (+43% YoY). The story is a decisive mix shift: Data Center & Networking revenue surged to 36% of total sales, eclipsing legacy segments. While profitability improved (Non-GAAP Op Margin +260bps YoY) despite Malaysia ramp costs, Operating Cash Flow efficiency deteriorated sharply in Q4, dropping to 8.1% of sales from 18.8% in Q3.
🐂 Bull Case
Data Center Computing revenue share expanded to 28% (up from 22% YoY) and Networking to 8%. The combined 36% exposure to AI-related end markets is driving both top-line acceleration and margin expansion due to the high complexity of boards required.
Despite significant headwinds from the Penang facility start-up costs, Non-GAAP Operating Margin expanded to 12.7% (vs 10.1% a year ago). As Penang yields improve and volume ramps, further leverage is unlocked.
🐻 Bear Case
Operating Cash Flow fell to $62.9M (8.1% of sales) in Q4, a sharp sequential decline from Q3's $141.8M (18.8% of sales). While likely due to working capital builds for the AI ramp, the magnitude of the drop warrants scrutiny.
The Automotive segment is a clear laggard, shrinking to 9% of revenue from 12% a year ago. Inventory adjustments and soft demand persist, dragging on the otherwise robust Commercial segment.
⚖️ Verdict: 🟢
Bullish. The successful pivot to AI/Data Center is overwhelming weakness in Automotive and initial drag from Malaysia. FY26 guidance for 15-20% growth confirms the 'Supercycle' thesis is intact, provided cash flow conversion normalizes.
Key Themes
Data Center & Networking Explosion
The mix shift toward AI infrastructure is accelerating faster than expected. Data Center Computing revenue share jumped to 28% in Q4 from 22% a year ago, while Networking rose to 8% from 7%. Collectively, these segments now generate over one-third of total revenue. This demand is not just volume; it drives 'favorable product mix,' boosting gross margins to 21.7% (Non-GAAP).
Cash Flow Volatility
Operating Cash Flow (OCF) exhibited a concerning drop in efficiency. After a stellar Q3 (18.8% of sales), Q4 OCF plummeted to 8.1% of sales ($62.9M). While rapid revenue growth often consumes working capital, the disparity suggests potential challenges in collections or inventory builds ahead of the Q1 ramp. Free Cash Flow was a meager $11.7M.
Operating Leverage & Execution
Non-GAAP Operating Income surged to $98.2M (+49% YoY), outpacing the 19% revenue growth. This demonstrates significant operating leverage. The Non-GAAP Operating Margin of 12.7% is a multi-quarter high, achieved despite the known drag from the Penang facility ramp. This indicates the underlying health of the core North American and Chinese operations is exceptional.
Automotive Market Deterioration
Automotive continues to shrink as a portion of the business, falling to just 9% of sales. While management cites 'inventory adjustments,' the persistent decline suggests structural weakness or share loss in a segment that was previously touted for EV growth potential.
Goodwill Impairment in RF&S
A $32.6M goodwill impairment charge was recorded for the RF&S Components segment in Q4. This indicates that the long-term outlook for this specific niche has deteriorated materially, despite the broader company success.
Aerospace & Defense Bookings
A&D remains a bedrock, though its relative share dipped to 41% due to the commercial boom. Crucially, the segment secured a book-to-bill of 1.35 in Q4, and total A&D backlog stands at a record $1.6B. This ensures stability if the commercial AI cycle cools.
Other KPIs
Accelerating. Up 53% YoY from $48.9M in 24Q4. This segment houses the Data Center business, and the profit growth vastly outpaced the 32% sales growth in the segment, confirming strong pricing power and mix benefits.
Stable. Up 4% YoY. While growth is modest compared to the AI-fueled Commercial segment, the $1.6B backlog provides high visibility for FY26.
While the exact ratio wasn't explicitly stated in the release text, cash remains robust at $501M against Long-Term Debt of $912M. With LTM Adjusted EBITDA rising to $456M, leverage remains conservative (<2.0x), providing ample dry powder for capex.
Guidance
Accelerating. The midpoint ($790M) implies ~22% YoY growth vs 25Q1, an acceleration from the 19% YoY growth seen in Q4. This signals that the AI ramp is still gaining momentum entering the new fiscal year.
Accelerating. The midpoint ($0.67) implies ~34% YoY growth vs the $0.50 reported in 25Q1. This suggests continued margin expansion.
Stable/Accelerating. Coming off 19% growth in FY25, guiding another 15-20% indicates management sees the 'AI Supercycle' as a multi-year trend rather than a one-off spike.
Key Questions
Cash Flow Conversion
Operating Cash Flow dropped to 8% of sales in Q4 despite record earnings. Is this purely working capital timing for the Q1 ramp, or are there collection issues with newer Data Center customers?
Penang Profitability Inflection
With revenues ramping, when exactly does the Penang facility cross the breakeven threshold? Is it still on track for 25Q3/Q4 targets set previously, or has the timeline shifted?
Automotive Outlook
With Automotive shrinking to 9% of sales, is this segment now non-core? Do you expect a rebound in FY26, or will AI displace Auto capacity permanently?
