Summary
KKR & Co. Inc. has agreed to acquire industrial machinery manufacturer Circor International Inc. in an all-cash transaction valued at $1.6 billion, taking the company private. Under the agreement announced in May 2026, KKR will pay $49 per share for all outstanding shares of Circor common stock, representing a 55% premium to the company's closing stock price immediately prior to the announcement. The transaction values Circor's equity at approximately $1 billion.
The acquisition marks KKR's continued investment in the flow-control equipment market, a sector that encompasses products and services used to manage and control liquids and gases, including pumps, valves, compressors, and meters. Circor serves multiple end markets including oil and gas, industrial manufacturing, aerospace and defense, and commercial aviation. The company's customer roster includes major commercial airlines and the U.S. Department of Defense, providing KKR with exposure to sectors characterized by stable demand and long-term contractual relationships. Circor employs approximately 3,100 workers and operates as a manufacturer of pump and valve systems.
Circor Chief Executive Officer Tony Najjar stated that "KKR will help us expand our presence in the flow-control space," signaling alignment between the company's management and the private equity firm's strategic direction. The transaction follows Circor's disclosure in March 2025 of irregularities in its financial statements and subsequent engagement with an independent accounting firm, which prompted preliminary discussions regarding a potential sale. Financial advisors to Circor included Evercore, J.P. Morgan Securities LLC, and Ropes & Gray LLP, while Citi and Kirkland & Ellis LLP advised KKR.
Upon completion of the transaction, Circor will operate as a wholly owned subsidiary of KKR's investment funds and will no longer be listed on any public securities exchange. The transaction represents KKR's strategy to consolidate industrial infrastructure and manufacturing assets that serve mission-critical applications across diverse industrial and defense sectors.
