Agenus (AGEN) filed a registration statement Friday for the potential resale of up to 78 million common shares by selling securityholders.

The shares include about 1.6 million outstanding common shares, 21.4 million shares issuable upon the exercise of pre-funded warrants and 54.9 million shares issuable upon the exercise of purchase warrants.

Agenus said it would receive proceeds only from any cash exercise of the warrants, which it intends to use for general corporate and working capital purposes. It will not receive any proceeds from sales of common stock by the selling securityholders.
