The Short Version

Flex, a company that builds and assembles products for other big brands, is paying $4.4 billion in cash for EPC Power, a California maker of equipment that converts electricity into the exact form computers can use.

Why care? The machines that run artificial intelligence swallow enormous amounts of electricity, and the unglamorous boxes that deliver it cleanly have become the hard part to get. Flex is betting the shortage is in the electrical plumbing, not the chips.

The deal is expected to be completed by the end of 2026.

Flex Ltd. (NASDAQ: FLEX) has agreed to acquire EPC Power Corp., a Poway, California designer and manufacturer of power conversion systems, for $4.4 billion in cash. The parties signed a Stock Purchase Agreement on September 3, 2026, under which Flex subsidiary ACS Acquisitions, Inc. buys all equity in EPC Power from Charge Parent, LLC, the holding vehicle for controlling shareholders Goldman Sachs Alternatives and Cleanhill Partners. Flex disclosed the agreement in an 8-K filed with the SEC on September 4, and is a party to the contract solely to guarantee its subsidiary’s obligations.

Flex’s announcement puts EPC Power’s calendar 2026 revenue at approximately $800 million, with roughly 40% organic growth expected in 2027 and EBITDA margin expanding by double-digit percentage points to approximately 30% that year. EPC Power says it has more than 15 GW deployed across 62 countries, and that annual U.S. manufacturing capacity will surpass 30 GW in 2027. The transaction is expected to close in the fourth quarter of 2026, subject to Hart-Scott-Rodino antitrust clearance and other customary conditions, after which EPC Power joins Flex’s Cloud and Power Infrastructure segment.

Executive Summary

This is a contract manufacturer paying a technology-company price. Flex has built its business designing and building hardware for other brands; EPC Power builds the equipment that sits between the grid and the server rack — rectifiers, DC-DC converters and grid-forming inverters, with solid-state transformers described in Flex’s announcement as planned development. Flex’s stated thesis, in CEO Revathi Advaithi’s words, is that “a generational shift in power architecture is underway,” and that owning the conversion layer lets Flex sell data center infrastructure as an integrated system rather than as parts.

The financial architecture matters as much as the strategic one. The 8-K describes a “locked box” structure in which EPC Power’s enterprise value was fixed as of June 30, 2026, with contractual protections against value leakage until closing — a mechanism common in private equity exits that gives the seller price certainty. Flex simultaneously signed a commitment letter with Citigroup Global Markets, Bank of America and BofA Securities for a senior unsecured 364-day bridge facility of up to $4.4 billion, a backstop it expects to replace with a permanent mix of debt and equity.

The timing is the sharpest detail. Flex states in both the 8-K and its announcement that EPC Power will land inside the Cloud and Power Infrastructure business, which Flex plans to separate into an independent public company in the first calendar quarter of 2027 — weeks after the acquisition is expected to close. Flex is, in effect, buying a $4.4 billion asset and then handing it to shareholders in a new vehicle.

The Bottleneck Moved Downstream of the Chip

For three years the constraint on AI buildouts was accelerators. The constraint discussed in this transaction is different: getting utility power into a building fast, and then converting it into something a rack of GPUs can drink without destabilizing the neighborhood grid. AI training and inference clusters draw power in large, fast swings — thousands of processors ramping together — which is closer to an industrial arc furnace than to the steady hum of a traditional colocation hall. EPC Power’s marketing centers on exactly this problem, and Flex is paying for the claim that solving it is a durable business rather than a moment.

The technical hook is the shift toward 800-volt DC distribution inside the data center. Conventional facilities step voltage down repeatedly and convert between alternating and direct current several times before power reaches a chip, losing a slice at each stage; higher-voltage DC architectures cut the number of conversions and the copper needed to carry the current. Flex’s announcement says EPC Power’s platform is engineered for these architectures with capabilities across rectifiers and DC-DC conversion. The grid-forming piece is complementary: most inverters follow the grid, matching a frequency someone else sets, while grid-forming units can establish voltage and frequency themselves, which is what lets a site run on batteries through a disturbance or energize before the utility interconnection is fully mature.

What $4.4 Billion Buys, Priced Against Flex’s Own Forecast

Work the disclosed numbers and the price becomes legible. Against approximately $800 million of calendar 2026 revenue, $4.4 billion is roughly 5.5 times sales. Apply the stated 40% organic growth and 2027 revenue lands near $1.1 billion; at the stated approximately 30% EBITDA margin, that implies something in the neighborhood of $330 million of 2027 EBITDA, or about 13 times forward earnings before interest, taxes, depreciation and amortization. Those multiples are derived arithmetic from Flex’s own projections, not company-stated figures, and they hold only if both projections land.

The margin guidance contains its own admission. If EBITDA margin expands by “double-digit percentage points” to reach approximately 30%, the 2026 margin is by definition 20% or below. Flex is paying today for a profitability structure that does not yet exist, on the expectation that mix shift toward data center product and scale in U.S. manufacturing delivers it. That is a defensible bet in a supply-constrained market — pricing power tends to follow scarcity — but it is a bet, and it is the single assumption most worth revisiting when the combined business reports actual results.

Buying an Asset You Plan to Give Away

Flex has told investors it will separate its Cloud and Power Infrastructure portfolio into an independent public company in the first quarter of 2027. EPC Power is being bought into that segment in the fourth quarter of 2026. The sequencing is deliberate: it makes the entity that goes public materially larger, faster-growing and more differentiated than it would otherwise be, and it moves the story of that company from “builds infrastructure hardware to order” toward “owns the power conversion layer.”

It also raises a capital-structure question that the filings flag rather than answer. Flex says it is evaluating financing alternatives and expects a combination of debt and equity, with committed financing from Citi and Bank of America standing behind it. Which balance sheet ultimately carries that debt — Flex’s or the new company’s — shapes both entities. Flex’s own forward-looking statement language lists the ability to achieve anticipated capital structures, credit ratings and financing in connection with the spin-off among its risks, which is an unusually direct acknowledgment that the two transactions are financially entangled. There is also a calendar risk: the purchase agreement’s outside date is December 31, 2026, subject to two automatic three-month extensions, meaning a slow antitrust review could push closing past the intended separation date.

Domestic Manufacturing as the Second Product

EPC Power’s pitch is not only technical. Flex describes U.S.-based engineering and manufacturing, and EPC Power’s own announcement says it expanded its domestic manufacturing footprint nearly tenfold under Goldman Sachs Alternatives and Cleanhill Partners, which first invested in 2021. In a market where electrical equipment lead times are a scheduling input and where tariff exposure and procurement rules increasingly favor domestic content, capacity located in the United States is a commercial asset in its own right, distinct from the merits of the hardware.

For buyers, the practical consequence is consolidation of the supply chain. A hyperscaler or colocation developer that previously bought conversion equipment, cooling and IT integration from separate vendors can, in principle, buy a larger integrated block from one supplier — faster to specify, but a heavier dependency. For other electronics manufacturing services firms, the transaction sets a marker: this asset was priced as differentiated intellectual property, not as assembly capacity, and the pool of independent power conversion specialists available to buy is not deep. For established power-equipment vendors, a well-capitalized new competitor now sits inside a manufacturing organization with a footprint spanning 30 countries.

Background

Flex Ltd. is one of the largest electronics manufacturing partners in the world, designing and building products for other brands across a footprint spanning 30 countries. In recent years it has pushed beyond assembly into data center power, cooling and IT infrastructure, organizing that work in a Cloud and Power Infrastructure segment that it has told investors it intends to separate into a standalone public company in the first quarter of 2027. Acquiring a power conversion specialist into that segment shortly before separation changes what the new company will look like on its first day of trading.

EPC Power was founded in 2010 in California and spent most of its life supplying inverters to the utility-scale battery storage market. Cleanhill Partners invested in 2021 on the thesis that power conversion would become critical as renewables, grid modernization and digital infrastructure converged; Goldman Sachs Alternatives later joined as a controlling shareholder. AI data centers then arrived as a second, larger market for the same core competence, because a building drawing power in large, rapid swings needs the same conversion and grid-stabilization hardware that a battery plant does — which is the convergence Flex is paying for.
