Suncor Energy Inc. will acquire Petro-Canada in a US$15.5 billion deal that will unite two of Canada's biggest oil companies, the companies announced Monday.

The move is expected to yield savings in operating costs of over CA (nyse: CA - news - people )$300 million (US$244 million) year, and annual capital efficiencies above CA$1 billion (US$812 million), the companies said.

Under the deal, Petro-Canada (nyse: PCZ - news - people ) common shareholders will receive 1.28 common shares of the expanded company for each share of Petro-Canada, while Suncor shareholders will receive new shares on a one-for-one basis.

The share exchange represents a 25 percent premium for Petro-Canada shares, based on a 30-day weighted average of the share price. Based on the closing price Friday, the deal values Petro-Canada at CA$19.12 billion (US$15.5 billion)

Petro-Canada shareholders will hold 40 percent of the enlarged company and Suncor shareholders will hold 60 percent. Both companies are based in Calgary.

Monday's announcement marks the creation of the largest oil and gas company in Canada by market cap, though the merged entity will be smaller than other global heavyweights such as Exxon Mobil (nyse: XOM - news - people ) and ConocoPhillips (nyse: COP - news - people ), which boast market capitalizations of US$326.6 billion and US$55.97 billion respectively.

"This merger creates a made-in-Canada energy leader with the assets, cost structure and financial strength to compete globally," said Rick George, president and chief executive officer of Suncor, who will continue in those roles in the new company.
