Warren Buffett is known as a brilliant investor, not a flashy one. And his latest deal, the second largest in the history of Berkshire Hathaway, follows not only that one, but many of the legendary investors principles.

As first reported by Bloomberg, and other sources, the investment company, headed up by Buffett, will acquire a leading aerospace hardware supplier, Precision Castparts, for $37.2 billion; almost half of Berkshire Hathaway’s cash.

But although the investment is a substantial one, it appears to be a relatively safe one as well. Precision Castparts pulls in close to $3 billion in pre-tax profits per year, so from a cash flow perspective, this is right in line with where it should be. Furthermore, the company is in an industry with little competition, and has actually moved to successfully acquire many of the competitors they do have, so their marketshare is solid as well. They serve the biggest companies in the aerospace field, including Airbus and Boeing, and obviously, the aerospace hardware industry obviously has some pretty high barriers to entry. Analysts don’t expect Buffet to make many major changes to the operations of his newly acquired company, and his history would support those claims.

The move is indicative of a major change for Berkshire Hathaway though, as the company continues to pivot away from picking stocks, to fully acquiring entire companies. What do you think of the new move? Another savvy one by Buffett, it appears to be.
