Private equity firm Arcline Investment Management LP said Thursday it’s fully committed to its $57-a-share offer for flow-control-products company Circor International Inc. CIR, +4.25% and that it expects to get regulatory approval for the deal. Arcline, based in New York, said that any potential overlap between CIRCOR and Arcline’s portfolio companies represents a negligible part of CIRCOR’s business. The company operates in a highly fragmented and competitive sector. This statement was made a day following Arcline’s announcement of its bid. It is approximately 12% higher than the previously-agreed KKR & Company Inc. offer of $51 per share. KKR stated on Wednesday that they are confident in their offer to “maximize shareholder value while minimizing market, regulatory and industry risks”. KKR, in contrast to Arcline Investment Management whose funds own a competitor of Circor, Fairbanks Morse Defense (FMD), believes that its transaction does not present a risk of antitrust delay or failure to close, at the expense to Circor shareholders, given the lack competitive overlap. Arcline said that it’s offer was not contingent on obtaining funding, and presents “no significant executive risk” to Circor’s investors. Circor’s stock, which was not active in premarket, has increased 124% year-to-date, while S&P 500 , SPX, +0.04%, has risen 14%.
