Tower chairman Michael Stiassny says it will consider the impact on its business and whether a capital raising will be needed after the Commerce Commission rejected a bid by Vero Insurance to merge the two businesses.
Shares in Tower took a pounding at the opening of trading on the NZX this morning, falling 29 per cent to 90c after the commission's decision to knock-back the $1.40 a share offer.
The shares have since bounced back to 96c but are at the lowest they have been since February before Tower received a bid by Fairfax Financial Holdings to buy the company for $1.17 per share.
Vero, which is owned by Australia's Suncorp, fought off Fairfax, with its higher bid but needed approval from the commission for the deal because it is already a key player in the New Zealand insurance market.
But commission chairman Mark Berry said the merger would remove Tower as the only independent competitor to Vero and IAG with the scale and brand strength to compete across the personal insurance market.
