KKR announced August 3 it will acquire Integer Holdings in an all-cash transaction valued at approximately $5.7 billion, including debt assumption. Integer supplies cardiac rhythm management devices and neuromodulation components to medtech OEMs including Medtronic, Boston Scientific, and Abbott. The deal marks KKR's largest healthcare take-private since its $4.6 billion Envision Healthcare acquisition in 2018 and follows eighteen months of concentrated buying in the medical-device supply chain.
Integer recorded $1.48 billion in trailing-twelve-month revenue as of Q1 2025, operating two divisions: Cardio & Vascular (62% of revenue) and Portable Medical (38%). The company manufactures batteries, leads, enclosures, and components for implantable devices—low-margin, high-reliability work that large OEMs increasingly outsource. Integer's EBITDA margin held at 18.2% in 2024, compressed from 19.7% in 2022 as titanium and lithium costs rose 14% year-over-year. Public equity investors penalized the margin erosion; Integer shares traded at 11.3x forward EBITDA before deal rumors surfaced in mid-July.
KKR's thesis appears operational, not financial engineering. The firm has acquired six medical-device suppliers since January 2023, including surgical instrument maker Aesculap's distribution arm and infusion-pump component manufacturer Fresenius Kabi's device unit. Integer's customer concentration—Medtronic represents 22% of revenue, Boston Scientific 16%—mirrors the oligopoly structure KKR now serves across multiple portfolio companies. Taking Integer private eliminates quarterly earnings volatility and allows multi-year capital deployment into manufacturing automation. Integer's Tijuana and Juarez facilities, which produce 41% of company output, require roughly $220 million in incremental capex to automate battery-cell assembly and reduce reliance on manual enclosure welding, according to the company's 2024 investor day materials. Public markets rarely reward three-year payback automation projects; private equity can afford the patience.
The deal structure matters for medical-device allocators. Integer's enterprise value implies 13.8x LTM EBITDA, a 190-basis-point premium to publicly traded peers like TE Connectivity's medical division and Greatbatch's successor entities. KKR is paying for Integer's FDA-registered facilities and existing design-transfer agreements with OEMs—regulatory moats that take thirty to forty-eight months to replicate. If KKR consolidates Integer's purchasing with its other device suppliers, the combined entity could command 8-12% better pricing on titanium alloys and lithium chemistries, enough to restore EBITDA margins to 20% within eighteen months. That margin recovery, if executed, would justify the purchase multiple and set a new valuation floor for publicly traded device suppliers still trading at 9-11x EBITDA.
Operators should monitor two follow-on events. First, whether Integer's top-three OEM customers renegotiate supply agreements before deal close, expected in Q4 2025 pending HSR clearance and CFIUS review. Device OEMs historically insert change-of-control provisions that allow price reopeners; any disclosed amendments in Integer's proxy filing will signal whether KKR negotiated pricing stability upfront. Second, watch KKR's other device suppliers for bolt-on acquisitions in Q1 2026. The firm now controls enough component capacity to pursue vertical integration into subassembly work—higher-margin, stickier contracts that could compress publicly traded specialists like Nordson Medical or Cirtec.
Integer's exit leaves $18 billion in remaining public market cap across pure-play device component suppliers, down from $31 billion in early 2022. Private equity has removed seven such companies in thirty months.
The takeaway
KKR's $5.7B Integer take-private accelerates PE control of medical-device supply chains; public comps now trade with takeout premiums baked in.

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.
