TTM Technologies Inc. Common Stock (TTMI) : juste valeur

Thèse ACCE

TTM Technologies makes printed circuit boards, including the high-layer-count and rigid-flex boards used in AI servers, networking gear, and defense electronics, and it is one of the few US-based volume producers of these parts. Its edge is the scale and qualification it holds with large OEM and defense customers, which makes switching costs real and gives it a structural tailwind as AI infrastructure buildouts push demand for complex boards. Revenue growth of 37.4% is the headline, and the stock trades at 15.9x forward earnings against a trailing P/E of 52.5, which says the market expects earnings to catch up sharply with sales. The margins are the question: a 21.2% gross margin and 10.9% operating margin leave little room for error if pricing or mix turns, and the 13.3% ROE is respectable but not exceptional for a business this capital-intensive. The thesis is worth a deeper look if you believe the revenue ramp converts to operating leverage, and the next few quarters of margin progression will show whether it does.
