Drinks giant InBev has said it will “pursue all available avenues” to acquire Anheuser-Busch, prompting speculation that its $46.3bn (£23.7bn) offer for the brewer could go hostile.

Anheuser-Busch rejected InBev's offer last week as “financially inadequate and not in the best interests of Anheuser-Busch shareholders”, but in a statement released yesterday, InBev said it remained committed to its proposal.

“Our firm proposal of $65 per share reflects the full and fair value of the company,” said InBev CEO Carlos Brito. “InBev remains committed to the combination and will pursue all available avenues that would allow Anheuser-Busch shareholders a direct voice in the process.”
