Billionaire activist Carl Icahn slightly boosted his exposure to eBay by roughly $25 million in the fourth quarter, according to a regulatory filing on Tuesday.

Icahn added about 446,000 shares in the quarter, about a 1 percent increase in his overall position, nearly 46 million shares. His stake in the Internet commerce company is worth $2.6 billion.

A year ago, Icahn pushed eBay to separate its fast-growing PayPal payments unit. The company rejected him at the time but in September announced it would spin off PayPal after all. Last month, Icahn signed a settlement with the company to give him a board representation.
