NEW YORK (TheStreet) - It's a late Valentines for Zale Corporation (ZLC) shareholders. The Dallas, Texas based jeweler said on Wednesday it agreed to be bought by Signet Jewelers (SIG) - Get Report in an all cash deal, worth $21 a share, that comes at an over 40% premium to Tuesday closing share prices.

The $21-a-share deal values Zale Corporation at about $1.4 billion when counting the company's debt and could cement a strong run in stock markets by the jeweler. Prior to Wednesday, Zale shares had gained over 200% in the past 12-months. Still, the company's takeover comes at a price that is well below the company's pre-financial share price highs in excess of $30 a share.

Zale operates over 1,000 specialty retail jewelry stores around the U.S., Canada and Puerto Rico and a over 600 jewelry kiosks in its footprint as well. The company turned to profitability in 2013 after a series of annual losses in the wake of the Great Recession.

For Bermuda-based Signet Jewelers, the deal is a major push into the North American jewelry retail market. "This transformational acquisition further diversifies our businesses and extends our international footprint, opening the door to greater growth and innovation across the enterprise," Mike Barnes, Signet's CEO, said in a statement.

Barnes added that the deal will better optimize Signet's balance sheet, and further said that Zale CEO Theo Killion would continue to work with the combined company after the acquisition closes.

Signet's offer values Zale at about $1.4 billion, when including debt, or an enterprise value of 7.4 times the company's trailing 12-month adjusted earnings before interest, taxes, depreciation and amortization.

The deal is expected to boost Signet's earnings by high single-digits in the first full fiscal year after the close of the transaction. That guidance excludes acquisition accounting adjustments and one-time transaction costs.

Signet said it expects the acquisition to be financed through bank debt, other debt financing and the securitization of a significant portion of Signet's accounts receivable portfolio.

Golden Gate Capital, the beneficial owner of approximately 22% of Zale's common stock, said on Wednesday it has agreed to support the terms of Signet's offer.

Zale shares were trading higher by about 40% to $20.90. Signet shares were also trading higher by over 14% to $90.50.

J.P. Morgan acted as exclusive financial advisor and provided a fairness opinion to the board of directors of Signe. The bank also committed to provide bridge financing for the transaction. Weil, Gotshal & Manges acted as legal counsel to Signet. BofA Merrill Lynch acted as financial advisor and Cravath, Swaine & Moore acted as legal counsel to Zale.
