(Burger King buyout article updated with additional commentary and stock price movement.)

MIAMI (

TheStreet

) -- Shares of

Burger King Holdings

(BKC)

surged for the second day as the Whopper-and-fries chain agreed to be taken private by

3G Capital

for $4 billion, with the assumption of the company's debt.

Under the terms of the deal, Burger King shareholders will receive $24 in cash per share, a 45.9% premium to Burger King's closing price on Tuesday, before rumors of the buyout began circulating on Wall Street. It will be the second time in eight years that Burger King has taken itself private.

3G is led by Alexandre Behring, a former railroad executive who sat on the board of Jacksonville, Fla.-based

"We have great respect for the Burger King brand and the strong business that management, the employees and the franchisees have built," Behring said. "The iconic Burger King brand, its solid franchisee network and great product offerings make this a perfect fit for 3G Capital, which has a strong track record of long-term investments in global consumer brands and retail companies."

Burger King CEO and Chairman John Chidsey is expected to remain in his post until the buyout is closed, after which Behring and Chidsey will be co-chairmen.

Burger King shares soared 24.7% in late-afternoon trading on more than 40 times their average trading volume.

Stifel Nicolaus analyst Steve West told

TheStreet

that now is a good time to sell Burger King shares, arguing that the stock is unlikely to rise much higher.

Some arbitration shops may still make some money on the stock, potentially filing suits arguing for a higher-priced deal, but "I don't think any more upside will be material," he said.

The $24 per share agreement bested the estimates of

analysts, who expected Burger King to fetch between $19 and $22 per share. The firm also predicted that a string of private-equity takeovers of fast-food chains is likely to follow, given the strong performance of industry darlings McDonald's and

Rumors of a private equity buyout first surfaced early Wednesday, leading Burger King shares sharply higher as investors bought up shares in anticipation of a possible merger.

>>Burger King Takeover a Good Idea

Burger King has been facing serious issues lately, and analysts speculated Wednesday that a private equity takeover could help the struggling fast-food chain turn itself around.

"It may be best for the

Burger King concept to be out of the public eye for a while and allow the new management to concentrate on fixing its challenges," Janney Montgomery Scott analyst Mark Kalinowski told

TheStreet

.

Burger King recently posted better-than-expected fourth-quarter profits

of $49 million, or 36 cents per share, but the bottom-line figures were sharply lower than year-earlier results. Global comps fell 0.7%, with comps at U.S. and Canadian locations down 1.5%.

Kalinowski said Burger King's problems aren't necessarily unfixable as a public company, but that a private company is often able to do things it wouldn't be able to do if traded on an exchange. He argued that Burger King will have to heal its relations with its franchisees, relationships that have been strained for some time. It also must find a way not to be a

clone.

"Burger King needs to figure out how to position itself more meaningfully away from McDonald's and still grow their business," he said.

As part of a turnaround plan, 3G plans to build Burger King's international footprint. The chain already had 93 restaurants in Brazil and expects to open around 500 new franchised locations in Latin America over the next five years.

At some point in 2008 3G held a 6.7% stake in another struggling fast-food chain:

There have already been a number of restaurant stock takeovers in recent months. Notable among them: Mexican restaurant operator

Rubio's was taken private by Mill Road Capital earlier this year for $8.70 per share.

In July an affiliate of

Apollo Management

took

CKE Restaurants

private for $694 million. CKE owned Hardee's and Carl's Jr. fast-food chains.

"The right private owner might help one or more of these chains eventually become better, and likely smaller, competitors to

McDonald's," UBS wrote in a note to investors. The note tapped
