Flex Ltd. agreed Thursday to acquire EPC Power for $4.4 billion in cash, subject to customary adjustments. The transaction hands the Singapore-based electronics manufacturer full ownership of power conversion, distribution, and cooling infrastructure marketed directly to hyperscale data center operators building AI compute clusters. EPC Power's revenue run rate sits near $2 billion annually, with roughly 70% tied to data center power systems.
The deal closes a capability gap Flex has carried since exiting traditional server assembly. EPC designs and manufactures rack-level power distribution units, uninterruptible power supplies, and liquid cooling systems—hardware that sits between utility-grade transformers and the GPU racks consuming 40-80 kilowatts per rack in modern AI training facilities. Flex already supplies enclosures, backplanes, and thermal management components to the same customers. The acquisition folds power electronics into that stack, eliminating a handoff point where integration risk and margin leak to third parties.
The move matters because AI infrastructure is constrained by power delivery, not compute availability. Hyperscalers ordering 100,000-unit GPU clusters from Nvidia face 18-24 month lead times on utility interconnects and substations. That makes rack-level power efficiency and density a gating factor. EPC's portfolio includes 98% efficiency power conversion and modular designs that reduce installation time by 30-40% compared to legacy systems. Flex gains the ability to quote a single bill of materials from transformer to server tray, a posture that appeals to procurement teams managing $10-15 billion annual data center capital expenditure budgets.
The valuation implies 2.2x trailing revenue, in line with recent infrastructure hardware transactions but below the 3-4x multiples paid for pure-play AI enablers. That spread reflects EPC's exposure to legacy colocation and enterprise markets, which still represent 30% of sales. Flex is betting those segments decline slower than AI infrastructure grows. The company guided to $35-40 billion in total revenue for fiscal 2025; EPC adds $2 billion immediately and positions Flex to capture 15-20% of incremental data center power spending through 2027.
Operators should track two follow-on signals. First, watch for Flex to announce joint development agreements with Nvidia or AMD within 90-120 days. Those partnerships typically include co-location of engineering teams and shared IP around thermal interfaces, which would confirm Flex's intent to move upstream. Second, monitor EPC's customer concentration disclosures in the first post-close earnings report. If two customers represent more than 50% of EPC revenue, Flex faces re-negotiation risk as those buyers leverage the acquisition to extract price concessions.
The transaction closes in Q2 2025, subject to regulatory clearance in the U.S. and EU. Flex will fund the purchase with $2.5 billion in new term debt and $1.9 billion in cash on hand. That leaves the combined entity with a net debt position near $3 billion, manageable against $4.5 billion in trailing EBITDA but tight enough to limit acquisition capacity through 2026.
The takeaway
Flex pays 2.2x sales to own the power stack as AI clusters hit 80kW per rack; watch for Nvidia co-dev within 90 days.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.

This trade runs on hands, not desks. Imprint manufacturing & Komori heritage press through approved vendors · Canon high-speed secure-media operations is a craft floor — genuine Six Sigma discipline applied to ink, thread, foil, and registration, where a hundredth of an inch is the difference between a brand that reads serious and one that reads cheap. POPS4 is built by exactly those operators: independent, boots-on-the-ground engineers who carry their own book, read a client in microseconds, and put their name on every run. Beyond our own Virginia Beach floor, we work with a vetted network of craft manufacturers across the US — each meeting the highest excellence in QC standards in the industry, each a specialist in its own discipline — so apparel, hard-goods imprinting, media manufacturing, packaging, and secure printing all go to the bench built for them, coordinated from one accountable hub.
