Sard Verbinnen & Co. represents Alleghany Corp. as the insurer agrees to be acquired by Warren Buffett’s Berkshire Hathaway via an $11.6B cash deal.

The $848.02 per-share offer is a 16 percent premium to Alleghany’s 52-week high closing stock price.

Alleghany CEO Joe Brandon, a longtime friend of Buffett, called the deal a “terrific transaction for Alleghany’s owners, businesses, customers and employees.”

As part of BH, “each of Alleghany’s businesses will be exceptionally well positioned to serve its clients and achieve its full potential,” he added.

The deal, which is expected to close during the fourth quarter, does feature a 25-day “go-shop” period, in which Alleghany can seek a buyer with a better offer.

SV&C’s Paul Scarpetta, Drew Brown and Warren Rizzi represent Alleghany, which is based in New York.
