Dollar General has once again extended the deadline for its tender offer to acquire Family Dollar Stores, which has advised shareholders to reject the from its rival.

The company has extended its offer of US$80 per share in cash, including associated preferred share purchase rights, to 17:00 New York time on 31 October. The offer was previously set to expire on 8 October.

All other terms and conditions of the tender offer remain unchanged, Dollar General said.

Last month, Dollar General reaffirmed its commitment to acquiring Family Dollar Stores. It had been rejected based on antitrust regulatory considerations earlier in the month. Family Dollar's board has remained committed to its support of the pending $74.50 per share agreement with Dollar Tree.
