Frontier Airlines asks Spirit to delay vote as cracks emerge in deal

Frontier Airlines, facing likely defeat in its bid to merge with Spirit Airlines, is asking for another delay in a shareholder vote on the deal.

Frontier CEO Barry Biffle said in a letter made public Monday that his airline is very far from winning approval by Spirit shareholders, who are weighing a richer buyout offer from JetBlue Airways.

A shareholder vote at Spirit, already postponed three times, is scheduled for Friday.

Spirit's board has stood behind a February deal it struck with Frontier to join the two discount airlines.

However, we still remain very far from obtaining approval from Spirit stockholders based on the proxy data we received as of July 8, Biffle said to Spirit CEO Ted Christie and General Counsel Thomas Canfield. Biffle asked for another delay in the vote, until July 27, if the merger plan still lacks the votes for approval so that Frontier can continue to lobby Spirit shareholders.

Biffle said that if Spirit's board changes its mind and supports the JetBlue bid, Frontier would waive its right to match the offer.

Frontier is offering Spirit shareholders $4.13 in cash and about 1.9 shares of Frontier for every share of Spirit, or about $2.4 billion at Frontier's current share price. Spirit shareholders would own 48.5% of the combined airline.

JetBlue is offering $33.50 per share in cash, and up to $34.15 per share or about $3.7 billion including a ticking fee to cover a delay in closing the purchase.
