Transaction would value newsletter startup at around $250 million, sources say
All-cash deal would buy out Puck's existing institutional investors, sources say
Deal would exclude shares held by founders and reporters, who would retain editorial control, per source
NEW YORK, Aug 26 (Reuters) - Puck is in advanced talks for an investment from RedBird Capital Partners, in a move which will help fund the growth of the newsletter startup, the company confirmed in a statement to Reuters.

The deal with RedBird, a well-known investor in media and entertainment, will value Puck at around $250 million and involve the company's existing institutional investors selling to RedBird. This will give RedBird a significant stake in the platform, according to people familiar with the matter, who spoke on condition of anonymity.
