Why Is Integer Holdings Stock Up Today?

Integer Holdings shares rose 20.2% Friday, closing at $121.21, after the Wall Street Journal reported that KKR is nearing a deal to acquire the medical-device contract manufacturer at $127 a share, a price that would value the company at about $4.3 billion.

What was reported

The Journal, citing people familiar with the matter, said the private-equity firm's offer could be finalized and announced as soon as next week. Reuters, sourcing the same story independently, reported that KKR declined to comment and Integer did not immediately respond to a request for comment. No agreement has been signed, and a transaction at that price is not yet final.

Integer Holdings is a Plano, Texas-based contract manufacturer for medical devices. Rather than selling its own branded products, it builds components and finished devices for companies in cardiac rhythm management, neuromodulation, and cardio and vascular care -- work that puts it inside the supply chain of most major device makers without the brand recognition of one.

Why now

Integer opened a formal strategic review in April 2026 after receiving unsolicited interest from potential buyers, so this report reads as that process reaching a conclusion rather than an unexpected approach. Private-equity interest in outsourced medical manufacturing has been building through 2026 more broadly, alongside American Industrial Partners' purchase of Avanos Medical and the Blackstone-TPG agreement to acquire Hologic -- part of a wider push by buyout firms into device and healthcare-supply businesses with steady, recurring revenue.

Where the stock sits

Shares closed at $121.21, still below the reported $127 offer. That gap is typical for an unconfirmed report: it prices in the chance the terms change, the timeline slips, or the deal does not close at all, on top of the board approval and regulatory clearance any signed agreement would still need.

What to watch

The next concrete marker is a statement from either side: a confirmation, a denial, or continued silence past the "as soon as next week" timeline the Journal reported. If a deal is signed, the merger agreement will set the real terms -- price, break fee, and closing conditions -- which a leaked report cannot.
