NEW YORK ( The Deal) -- Burger King Worldwide ( BKW) confirmed Tuesday that it agreed to acquire Tim Hortons ( THI) in an $11 billion merger structured as a tax inversion.
The announcement comes one day after the two restaurant chains confirmed they were in talks about a deal.
See what TheStreet's Jim Cramer has to say about Tim Hortons:
The deal puts more pressure on McDonald's ( MCD) breakfast program, with Burger King getting one of Canada's largest coffee and breakfast chain operators. The new combined company will become the world's third-largest quick service operator behind McDonald's and Subway operator Doctor's Associates in terms of number of stores.
Oakville, Ontario-based Tim Hortons was once controlled by Burger King rival Wendy's ( WEN) .
Tim Hortons shareholders have the option to receive C$65.50 in cash and 0.8025 shares of the new company for each share, or either C$88.50 in cash or 3.0879 shares of the new company.
Miami-based Burger King has received a $12.5 billion commitment from JP Morgan Chase & Co. and Wells Fargo Bank NA to fund the cash portion of the deal. Warren Buffet's Berkshire Hathaway Inc. has also committed $3 billion in financing.
3G Capital, which owned a 70% stake in Burger King before the deal was announced, will own a 51% stake in the new combined company by converting its shares into equity. The private-equity firm took Burger King private in 2010 for $4 billion then took it public again in 2012.
The new combined will operate more than 18,000 restaurants worldwide, across 100 countries and will have about $23 billion in combined sales.
"We are excited to build on this progress as we continue to expand Burger King around the world and look forward to working with and learning from Tim Hortons as we together create the world's leading global restaurant business," said Burger King CEO Daniel Schwartz in a statement.
"As an independent brand within the new company, this transaction will enable us to move more quickly and efficiently to bring Tim Hortons iconic Canadian brand to a new global customer base," added Tim Hortons CEO Marc Caira in a statement.
What this transaction does is "give us the chance to share with the world what Canadians already know and love," Caira said on a conference call with reporters on Tuesday. "We will be able to leverage a global network and learn from their experience" in building a strong global QSR brand.
"We are very confident that we can grow much quicker in this ... battle called the U.S.," Caira said later on the call.
Looking toward 3G Capital's investment in Heinz and Anheuser-Busch InBev, "these are the examples we hope to follow with this transaction," Caira noted. As bottles of Heinz ketchup and InBev's beer are household names, putting Tim Horton's coffee and boxes of doughnuts "in the hands of more consumers around the world -- that is what today's announcement is all about," he said. "It's about growth."
There was no shortage of questions about the tax implications of the deal from reporters following prepared remarks. Executives repeated that while the holding company would be based in Canada -- the combined company's largest market -- Burger King, based in Miami, would continue paying U.S. taxes.
"We don't expect there to be meaningful tax savings, nor we do we expect there to be change to our tax rate," said Burger King CEO Daniel Schwartz.Schwartz will lead the new combined company and Caira will become executive chairman, while gaining a board seat. Even though the two brands will continue to operate independently out of their respective headquarters, they are going to call Canada their new home.

Since 3G Capital has already voted in favor of the merger, it does not require additional Burger King shareholder approval, but it still must go through Tim Horton shareholders and regulators.
Burger King shares were down 3% to $31.42 on Tuesday, with its market capitalization near $11.05 billion. Tim Hortons shares were trading 8.8% higher, to $81.30, with its market cap near $10.8 billion.
