TTM Technologies is benefiting from a sharp mix shift toward AI infrastructure and aerospace and defense, with Q2 revenue up 37% and EPS up 71%. The stock still carries valuation and execution risk, but the report argues the growth runway supports a Buy.
TTM Technologies Inc (TTMI) has become a high-growth advanced electronics supplier with two powerful demand engines: artificial intelligence infrastructure and aerospace and defense. Q2 2026 revenue reached $1.0B, up 37% year over year, while non-GAAP EPS rose 71% to $0.99. Data center and networking revenue grew 91%, aerospace and defense revenue grew 14%, and adjusted EBITDA margin expanded to 16.6%.
The investment case rests on a favorable mix shift toward complex printed circuit boards, RF modules, mission systems, and high-reliability assemblies. TTM's N+M asymmetrical PCB ramp, Syracuse Ultra-HDI capacity, $1.7B aerospace and defense backlog, and $7B qualified defense pipeline give the company visible growth drivers. The 2026 outlook calls for approximately $4.4B of sales and non-GAAP EPS approaching $5.
The main counterweight is valuation and execution risk. Trailing P/E is 46.2x, beta is 2.1, 2025 free cash flow was approximately breakeven after $292.6M of capital expenditures, and debt remains material relative to cash. The company also operates in a fiercely competitive PCB and electronics market. For a moderate-risk investor with a medium-term horizon, the balance supports a Buy recommendation, but position sizing deserves discipline.
TTM Technologies, founded in 1978 and headquartered in Santa Ana, California, manufactures advanced printed circuit boards, substrates, RF components, microelectronic assemblies, and engineered mission systems. The company employs approximately 18,200 people and serves aerospace and defense, data center computing, networking, automotive, medical, industrial, and instrumentation customers.
TTMI's model extends beyond basic contract manufacturing. The company provides design-for-manufacturability support, PCB layout, simulation, testing, quick-turn production, specialized RF assembly, and integrated systems. This lets customers engage TTM during product development and continue through production, creating practical switching costs even though the company's manufacturing technology does not rely on significant proprietary patent protection.
The FY2025 10-K described a network of 24 specialized facilities across North America and Asia serving roughly 1,300 customers. That footprint gives TTM geographic breadth and access to specialized processes, but it also creates exposure to labor, logistics, currency, trade, and regulatory conditions across several jurisdictions.
The company reports three operating areas: Aerospace and Defense, Commercial, and RF&S Components. Recent reporting realigned RF and specialty activities into the Aerospace and Defense structure, so the most useful current comparison is between the A&D and Commercial operating segments.
Aerospace and Defense generated $1.28B of FY2025 sales, up 13.4% year over year. Q2 2026 A&D revenue was $382.8M, compared with $335.2M in the prior-year quarter, while segment operating income rose to $63.9M from $48.1M. A&D represented 37% of Q2 sales.
The segment combines advanced PCBs with RF and microwave assemblies, communications systems, radar products, surveillance systems, beamforming networks, and complete mission systems. Its customers include tier-one defense contractors, government agencies, and international defense organizations. Long qualification cycles and program-specific engineering work support customer retention.
Commercial produced $1.58B of FY2025 sales. Q2 2026 Commercial revenue rose to $621.6M from $395.6M, and segment operating income increased to $112.7M from $60.1M. Data center and networking accounted for 40% of Q2 sales and grew 91% year over year. Medical, industrial, and instrumentation represented 15% of sales and grew 33%, while automotive represented 8% and declined marginally.
RF&S Components generated roughly $40M of FY2025 sales. Its products include passive microwave components, ceramic substrates, custom ASICs, and high-reliability multi-chip modules. The dollar contribution is small relative to the other areas, but these products expand TTM's technical breadth and support the company's strategy of moving up the electronics value chain.

The most important near-term product opportunity is N+M, TTM's asymmetrical interconnect PCB technology. Management said the company had already delivered tens of millions of dollars of N+M product with yields performing well and expected approximately $600M of additional N+M activity in the second half of 2026.
Management said roughly one-third of the $600M would occur in Q3 and two-thirds in Q4, with improving yields supporting margin expansion. The Q3 2026 outlook calls for revenue of $1.10B to $1.14B and non-GAAP EPS of $1.21 to $1.27. That ramp makes N+M the clearest operational test for the next two quarters.
TTM's second flagship product family is its Ultra-HDI and advanced PCB offering for aerospace and defense. The new Syracuse facility begins initial volume ramping in Q3 2026, with full capacity expected in 2028. These products support high-frequency, high-density applications where reliability, weight, size, and power consumption matter.
The product portfolio also includes AN/APS-153 multi-mode radar systems, MOSAIC AESA radar products, communications suites, RF modules, multi-chip modules, and beamforming networks. This combination gives TTM exposure to both recurring production programs and new technology insertion.
TTM's innovation advantage is practical rather than patent-driven. The company combines engineering design, advanced interconnect manufacturing, RF expertise, testing, and system integration. That combination allows an OEM or defense contractor to move from prototype to production through a single supplier.
The 2025 10-K identifies HDI, rigid-flex, advanced substrates, high-layer-count boards, and RF integration as important technology areas. These products address faster data transmission, thinner packaging, thermal management, and lower power consumption. Those requirements are rising in AI servers, networking equipment, radar, medical robotics, and automated test equipment.
TTM also benefits from early customer engagement. Design-for-manufacturability support and rapid prototype production can establish TTM before a product reaches volume production. The resulting qualification history and process knowledge create a useful execution moat, even though competitors such as AT&S, Unimicron Technology, Sanmina, and Jabil also possess substantial manufacturing scale.
Operational execution is becoming a larger part of the investment case. Q2 2026 gross margin reached 21.9%, up 100 basis points year over year, while operating margin improved to 13.8% from 11.1%. Adjusted EBITDA margin rose to 16.6% from 15.0%, reflecting volume and product mix.
TTM's Penang facility is approaching breakeven after a ramp focused mainly on medical, industrial, and instrumentation products, with additional N+M support for data center customers. Syracuse is beginning Ultra-HDI production, while the Wisconsin site is being developed as an innovation center with selective production capability. Management paid less than $20M for the Wisconsin site, limiting the financial burden of that option.
Capital intensity is significant. FY2025 operating cash flow was $291.9M against $292.6M of capital expenditures, leaving approximately breakeven free cash flow. The spending supports N+M, Ultra-HDI, capacity expansion, and technology upgrades, but it raises the execution hurdle because revenue growth must translate into higher yields and cash generation.
Supply pressure has been more visible in lower-complexity automotive materials than in TTM's highest-end data center products. Management said suppliers are shifting toward higher-complexity materials and that TTM continues to secure materials with reasonable lead times. That mix is favorable for TTM, although the company's global footprint still exposes it to shortages, freight disruption, currency movements, and trade restrictions.
Third-party estimates place the global electronics manufacturing services market at approximately $620.2B in 2025 and $663.3B in 2026, with one estimate reaching $909.3B by 2031. Broad EMS growth is expected in the mid-single digits, while advanced interconnect, high-density boards, and AI infrastructure are growing faster than the overall market.
TTM is positioned in the higher-complexity portion of that market. Its products support AI servers, networking switches, radar, surveillance, medical devices, instrumentation, and advanced automotive electronics. The distinction matters because TTM's economics depend less on low-cost assembly volume and more on engineering content, qualification, process control, and yield.
AI is the strongest current commercial demand driver. Data center and networking revenue grew 91% in Q2 2026, reached 40% of sales, and is expected to represent 49% of Q3 sales. Management expects full-year 2026 data center and networking revenue to more than double year over year.
Defense electronics provide a second growth pool. TTM reported a 1.3 book-to-bill ratio for A&D in Q2, a $1.7B program backlog, and more than $7B of qualified potential business. These figures do not guarantee future revenue, but they provide stronger demand visibility than a purely spot-market PCB business.

TTM serves original equipment manufacturers, electronic manufacturing services providers, original design manufacturers, distributors, and government agencies. The end markets include aerospace and defense, data center computing, networking, automotive, medical, industrial, and instrumentation.
Management described more than 10 large hyperscaler and networking customers, with major customers distributed between Commercial and A&D. One customer in each reporting segment qualifies as a 10% customer, and another Commercial customer is approaching that threshold. The distribution across segments reduces dependence on a single market, but large-account exposure remains important.
Medical customers are also gaining importance. Management said the performance of its top five medical customers in the first half of 2026 exceeded internal expectations by more than two times. Demand was linked to continuous glucose monitoring, surgical robotics, electrophysiology, and automated test equipment.
The customer relationship is strongest when TTM enters during design and qualification. That approach supports longer program lives and higher switching costs, especially in defense and medical applications. It also raises the consequences of quality failures, late deliveries, or yield problems.
TTM's PCB competitors include AT&S, Founder Technology Group, Gold Circuit Electronics, Isu Petasys, Kinwong Electronic, Unimicron Technology, Victory Giant Technology, WUS Printed Circuit, Sanmina, Tripod Technology, and Zhen Ding Technology. These companies compete on capacity, price, technology, geographic reach, quality, and delivery speed.
In RF and aerospace and defense, TTM identifies BAE Systems, Honeywell, Crane Aerospace & Electronics, Hensoldt, Mercury Systems, Leonardo DRS, Smiths Group, Thales, and Curtiss-Wright among its competitive set. These companies do not all compete across the same product categories, but they illustrate the breadth of the market.
TTM's competitive strength is its combination of advanced PCBs, RF components, microelectronics, assemblies, and mission systems. Flex, Jabil, and Sanmina offer greater broad EMS scale, while specialized PCB manufacturers can compete aggressively in individual technologies or regions. TTM therefore earns differentiation through breadth and execution rather than through an exclusive technology monopoly.
The competitive risk is real. TTM's 2025 10-K states that rivals can have greater financial resources, broader sales channels, lower-cost locations, more capacity, or faster response times. A downturn in commercial electronics would increase pricing pressure, particularly in lower-complexity products.
The macro backdrop is favorable for TTM's two largest growth themes. AI infrastructure is increasing demand for high-density, high-speed interconnect products, while defense modernization is increasing demand for radar, communications, surveillance, and missile-related electronics. TTM's Q2 results provide direct evidence of both forces: data center and networking grew 91%, and A&D grew 14%.
Geographic diversification is both an advantage and a risk. TTM manufactures in the United States, Taiwan, Malaysia, and other international locations, giving customers more supply-chain options. The same footprint creates exposure to tariffs, export controls, local regulation, labor costs, and cross-border logistics.
Currency volatility affected Q2 2026 results. TTM recorded a $4.9M foreign-exchange loss as the U.S. dollar weakened. The company also recorded a $14M noncash pretax unrealized loss on a cross-currency swap related to the Swiss Technology Group transaction. These items did not alter the underlying demand picture, but they show how international expansion can add earnings volatility.
Defense demand is more resilient than consumer electronics demand, but it still depends on appropriations, program timing, contract awards, and production execution. AI demand is structurally attractive, but data center customers can adjust inventory and capital spending quickly. TTM's combination of end markets reduces, rather than eliminates, cyclicality.
Debt remains material relative to cash, and 2025 free cash flow was roughly breakeven after $292.6M of capital expenditures.

Get Full Access →TTM Technologies has moved beyond a conventional PCB manufacturing story. Its Q2 2026 results show a company benefiting from AI data center construction, defense modernization, medical electronics, and higher-value interconnect products at the same time. Revenue reached $1.0B, adjusted EBITDA margin reached 16.6%, and the company produced its seventh consecutive quarterly earnings beat in the reported history.
The next stage depends on conversion. The $600M N+M second-half ramp must produce stronger yields, Syracuse must build Ultra-HDI capacity, and the $1.7B A&D backlog must become revenue and cash flow. The balance sheet can support the plan, but 2025's approximately breakeven free cash flow shows why growth alone is not enough.
At the $175 fair value estimate, TTMI offers a constructive medium-term profile without ignoring volatility or valuation risk. The Buy recommendation is therefore tied to operating execution, not market enthusiasm. If TTM converts its backlog and technology ramps into durable free cash flow, the company can strengthen its position as a specialized supplier to the next generation of AI and defense electronics.
