Merger activity decreased last week with three new deals announced and two deals completed.

Alleghany Corporation (NYSE:Y)

Incorporated in 1929 and based in New York, Alleghany Corporation was originally created as a holding company for railroad interests by railroad entrepreneurs Oris and Mantis Van Sweringen. Alleghany operates in three segments: reinsurance, insurance, and Alleghany Capital, providing property and casualty reinsurance and insurance products in the United States and internationally.

Berkshire Hathaway (BRK.A, BRK.B) announced last week that it will acquire all outstanding Alleghany shares for $848.02 per share in cash, for a total equity value of approximately $11.6 billion, representing a premium of 29% to Alleghany’s average stock price over the last 30 days. The transaction aligns well with Berkshire's interests in both insurance and reinsurance.

According to an article from S&P Global, "Another element that makes the $11.6 billion deal attractive to Berkshire is that Alleghany has a brokered reinsurance unit, whereas The Berkshire Hathaway Reinsurance Group, the company's reinsurance arm, sells directly to clients. A quota share with Alleghany's reinsurance company has given Berkshire good insight into the business and increased its broker market distribution, UBS analyst Brian Meredith said in a note."

This deal will also unite Warren Buffett with his 'long time friend', Alleghany CEO Joe Brandon. Brandon was the CEO of General Re from 2001 to 2008 before joining Alleghany as the president of its insurance group in 2011.

This is one of the five largest acquisitions in Berkshire's history and it ends Buffett's six-year drought of large acquisitions.

After the transaction is completed, Alleghany will operate as an independent unit of Berkshire. The agreement includes a 25-day "go-shop" period, during which Alleghany may solicit other acquisition offers. According to the merger agreement, no break-up fee would be owed to either party if the merger fell through.

Deals In The Works

There was one new deal announced in the Deals in the Works section last week.

On March 21, 2022, Switch (SWCH), a data-center operator, announced that it is exploring strategic options including a sale.

On March 25, 2022, Bloomberg reported that Gulfport Energy (GPOR) had discussed merging with rival oil and gas explorer Ascent Resources. We had added Gulfport Energy as a potential deal in the works on September 23, 2021, when Reuters had reported that, after emerging from bankruptcy earlier in 2021, the company was exploring strategic options including a possible sale. GPOR's price after this announcement was $79.98.
