Private‑equity firm KKR agreed to sell its Circor Aerospace unit to Parker Hannifin for $2.55 billion. Circor Aerospace, based in Burlington, Massachusetts, builds flow‑control components for industrial, naval and aerospace customers. The deal follows KKR’s 2023 purchase of the broader Circor business for $1.8 billion, leaving the firm with the naval and industrial segments. The acquisition aligns with Parker’s strategy to broaden its industrial automation footprint.

CEO Saif Siddiqui will remain at the helm of the remaining Circor businesses, overseeing the naval and industrial lines that KKR retained. The transaction is slated to close in the second half of 2026, subject to customary regulatory approvals. For Parker Hannifin, the acquisition expands its fluid‑control portfolio and strengthens its position in high‑growth aerospace markets. The integration should yield cost efficiencies.

The sale represents a roughly 42% premium over KKR’s original outlay, signalling confidence in Parker’s ability to integrate and grow the aerospace line. Analysts note that the deal could lift Parker’s earnings per share once synergies materialise, while KKR recoups capital for new investments. The move also adds defense contracts to Parker’s government pipeline, reshaping the competitive dynamics of the flow‑control sector.
