Precision Castparts

Precision Castparts does not function as an investment firm. It is an operating company. All capital allocation decisions — including the 35-plus acquisitions that built the company — were historically led by former Chairman and CEO Mark Donegan. Since Berkshire Hathaway's 2016 acquisition, major capital deployment requires approval from Warren Buffett at the parent level (per the firm's official communications).

The firm is an aerospace manufacturer, not a venture investor. The Altss tag "Venture Capital (General)" reflects historical corporate development activity under Mark Donegan, who pursued aggressive M&A to acquire new manufacturing technologies. Today, any investment activity is operational capital expenditure on plant and equipment, not financial portfolio investing.

Berkshire Hathaway acquired Precision Castparts in January 2016 for $37.2 billion in an all-cash transaction (per the firm's official communications). PCC now operates as a wholly owned subsidiary. Warren Buffett serves on the oversight board, and PCC's financial results are consolidated into Berkshire's manufacturing segment.

Boeing is one of PCC's two largest customers alongside General Electric. The firm supplies approximately $1.5 million in cast and forged components for every Boeing 787 Dreamliner, covering engine structures, airframe components, and fasteners. PCC is also a significant supplier on the 737 MAX program.

PCC operates a global manufacturing network. Key domestic facilities include a large-parts campus and corporate headquarters in Portland, Oregon, a titanium melting and forging plant in Ravenswood, West Virginia, and a forging operation in Grafton, Massachusetts. The firm also maintains international manufacturing sites supporting its aerospace and energy customers.

Mark Donegan, who led PCC's transformation through more than 35 acquisitions during his tenure as CEO and Chairman, remained with the company for a transition period following the January 2016 Berkshire acquisition. Kevin Stein ultimately succeeded him as Chief Executive Officer and leads the firm today.

The firm operates a corporate volunteer program through which employees participate in community initiatives. PCC does not maintain a separately structured private foundation comparable to the vehicles seen at single-family offices or tech-origin fortunes.
