Why Berkshire Hathaway Is Buying Alleghany (Y) For About $11.6 Billion

By Amit Chowdhry ● Mar 21, 2022
  • Berkshire Hathaway (NYSE: BRK-A; BRK-B) is buying Alleghany Corporation (NYSE: Y) in a deal valued at $11.6 billion. These are the details.

Berkshire Hathaway (NYSE: BRK-A; BRK-B) and Alleghany Corporation (NYSE: Y) jointly announced they have entered into a definitive agreement under which Berkshire Hathaway will acquire all outstanding Alleghany shares for $848.02 per share in cash. The transaction — which was unanimously approved by both Boards of Directors — represents a total equity value of approximately $11.6 billion. 

The acquisition price represents a multiple of 1.26 times Alleghany’s book value at December 31, 2021, a 29% premium to Alleghany’s average stock price over the last 30 days and a 16% premium to Alleghany’s 52-week high closing price.

The deal is expected to close in the fourth quarter of 2022, subject to customary closing conditions, including approval by Alleghany stockholders and receipt of regulatory approvals. And Alleghany will continue to operate as an independent subsidiary of Berkshire Hathaway after closing. Jefferson Kirby, who controls 2.5% of Alleghany common shares, intends to vote his shares for the transaction.

Under the terms of the definitive merger agreement, Alleghany may actively solicit and consider alternative acquisition proposals during a 25-day “go-shop” period. And Alleghany has the right to terminate the merger agreement to accept a superior proposal during the go-shop period, subject to the terms and conditions of the merger agreement. There can be no assurances that the “go-shop” process will result in a superior proposal, and Alleghany does not intend to communicate developments regarding the process unless and until Alleghany’s Board of Directors makes a determination requiring further disclosure.

Goldman Sachs & Co. LLC is serving as financial advisor and Willkie Farr & Gallagher LLP is serving as legal advisor to Alleghany. Munger, Tolles & Olson LLP is serving as legal advisor to Berkshire Hathaway.


“Berkshire will be the perfect permanent home for Alleghany, a company that I have closely observed for 60 years. Throughout 85 years the Kirby family has created a business that has many similarities to Berkshire Hathaway. I am particularly delighted that I will once again work together with my long-time friend, Joe Brandon.”

— Warren E. Buffett, Berkshire Hathaway’s Chairman and Chief Executive Officer

“My family and I have been significant shareholders of Alleghany for over 85 years and are proud that our ownership will culminate through this compelling transaction with Berkshire Hathaway. Not only does this deal provide substantial and certain value to stockholders, but it provides a rare opportunity to join forces with a like-minded and highly respected investor and business leader. Berkshire Hathaway’s support, resources, and expertise will provide added benefits and opportunities for Alleghany and its operating businesses for many years to come.”

— Jefferson W. Kirby, Chair of the Alleghany Board of Directors

“This is a terrific transaction for Alleghany’s owners, businesses, customers, and employees. The value of this transaction reflects the quality of our franchises and is the product of the hard work, persistence, and determination of the Alleghany team over decades. As part of Berkshire Hathaway, which epitomizes our long-term management philosophy, each of Alleghany’s businesses will be exceptionally well positioned to serve its clients and achieve its full potential.”

— Joseph P. Brandon, Alleghany’s President and Chief Executive Officer
