Data center boom drives TTM to record billion dollar quarter
- TTM is shifting from standard circuit boards toward higher-value electronics for aerospace, defense, and AI data centers.
- Data Center Computing and Networking sales nearly doubled in the second quarter of 2026 due to heavy AI demand.
- Aerospace and defense combined with data centers now account for nearly 80 percent of total sales.
- The company is expanding into Europe through the acquisitions of Swiss Technology Group and ILFA.
- The price already asks a lot, so Finn's view requires execution at Penang, steady AI orders, and Syracuse progress.
A concentrated mix with a price test
TTM is no longer only a plain printed circuit board story. The bull case is that the company is becoming a more specialized electronics supplier under new CEO Edwin Roks. That means more work tied to national defense programs and AI data center hardware, where products are harder to build and carry better margins.
The strongest parts of the story are clear. Data Center Computing and Networking grew 91 percent year over year in the second quarter of 2026, driving the company to its first billion dollar revenue quarter. Aerospace and Defense remains a pillar. Together, defense and data centers now make up nearly 80 percent of sales.
The bear case revolves around execution and concentration. The Penang, Malaysia plant is ramping slower than hoped, though management sees it nearing breakeven. The AI-linked data center business depends on a small group of large customers. Automotive is dealing with softer demand and supply chain material constraints.
Finn's score fits that split view. Growth and operating performance look strong, but valuation is the hard part. The stock needs proof that the new combined AI segment will maintain its growth curve and that the Syracuse, New York project stays on track for initial low-rate production.
Advanced boards for harder jobs
TTM makes printed circuit boards, often called PCBs, which connect chips and other electronic parts. It also makes radio frequency components, RF subsystems, and engineered electronics used in demanding systems.
The company earns money by building these parts for end markets like aerospace, defense, data centers, networking, automotive, and medical devices. The better business comes when TTM does more than build a standard board. Engineered products and advanced boards can be much more differentiated.
Expanding physical capacity matters to the next phase. Penang gives commercial customers a highly automated option outside China. Syracuse will add domestic capacity for very dense circuit board technology required by defense customers. TTM also recently established a footprint in Europe by acquiring facilities in Switzerland and Germany.
This model breaks if new plants miss cost targets, if AI customers pause orders, or if commercial customers keep cutting inventory. It also faces normal manufacturing pressure from labor shortages, supply chain constraints, and a company-wide ERP system upgrade.
What TTM sells
High-Density Interconnect PCBs
HDI boards pack more connections into less space. They matter for advanced electronics, including AI infrastructure and defense systems.
N+M Asymmetrical Boards
A newly ramping technology for data centers. Management expects a massive revenue contribution in the second half of 2026.
Rigid-Flex PCBs
Rigid-flex boards combine firm and bendable sections. They are useful where space, weight, and reliability matter.
RF Components and Subsystems
RF products help send and receive radio signals. This fits defense, aerospace, and other systems where signal quality matters.
Engineered and Integrated Electronics
These are higher-value systems, not only bare boards. They are central to TTM's defense strategy and now make up more than half of defense revenue.
Standard Printed Circuit Boards
Standard boards remain part of the base business. They can be more cyclical because demand moves with customer production and inventory cycles.
Ultra-HDI Domestic Capacity
The Syracuse expansion is aimed at domestic ultra-HDI needs. It is not fully producing yet, so the payoff depends on execution through 2026.
Where revenue comes from
This mix reflects second quarter 2026 end market sales. Management formally consolidated its reporting units into Aerospace and Defense, and Commercial in early 2026.
What could go wrong
Penang ramp stays slow
High impact · Medium oddsThe Penang, Malaysia facility is a key part of TTM's plan to serve customers outside China. A slower ramp can hurt margins because the company pays for labor, tools, and overhead before the plant reaches enough volume.
AI orders are too concentrated
High impact · Medium oddsThe combined Data Center and Networking segment is growing heavily on generative AI applications. The risk is that a few large customers drive much of that growth. If one delays a program, the segment could slow fast.
Material supply chains tighten
Medium impact · High oddsProducers of copper-clad laminates are shifting away from lower complexity materials. This creates supply chain pressure and potential shortages in segments like Automotive.
Syracuse misses milestones
Medium impact · Medium oddsTTM broke ground on the Syracuse expansion in late 2024 and expects initial low-rate production in 2026. The project is important for domestic ultra-HDI defense demand. Delays could push out the margin and growth benefit.
ERP upgrade disrupts operations
Medium impact · Medium oddsTTM has warned that issues during its enterprise resource planning system upgrade could hurt operating results or make the business harder to manage. ERP software controls core tasks like purchasing, production planning, shipments, and accounting.
In one breath
What does TTM Technologies do?
TTM makes printed circuit boards, RF components, and engineered electronics. Its products go into defense systems, AI data center hardware, cars, medical equipment, industrial tools, and networking gear.
Why is AI important to TTMI?
Generative AI is driving intense demand across both Data Center Computing and Networking, prompting the company to merge them into a single segment for 2026.
Why does defense matter so much for TTM?
Aerospace and Defense is historically the largest segment. TTM has shifted that business toward engineered and integrated electronic products, which can be more differentiated than standard circuit boards.
What are the main things to watch next?
Watch whether Penang reaches breakeven, whether AI data center orders stay strong, and whether the new CEO shifts strategic priorities. Also watch when Automotive inventory cuts end.
