In a press release, Burbank, Calif.-based Disney (DIS: news, chart) said its board "will carefully evaluate" Comcast's unsolicited proposal.
During a conference call with securities analysts, Comcast CEO Brian Roberts said he hoped that Disney's board would "do the right thing" and accept the terms.
"It's a logical next step" for Philadelphia-based Comcast (CMCSK: news, chart) (CMCSA: news, chart) to expand its drive to add more content capabilities, Roberts said during a press conference. Discuss the bid.
Disney's stock rocketed $3.31, or nearly 14 percent, to $27.39, after earlier hitting a 52-week high of $28. Comcast fell $2.40, or 7 percent, to $31.53.
Terms of the deal, which includes the assumption of $11.9 billion in Disney debt, call for Comcast to exchange 0.78 shares of its Class A common stock for each Disney share outstanding. Disney is a component of the Dow Jones Industrial Average.
Based on Tuesday's closing prices, the deal would value Disney stock at $26.47 each, a 9.9 percent premium, and above the previous 52-week high of $25.08.
Disney shareholders were celebrating the prospect of Disney's stock price rising during what could become a lengthy and contentious takeover battle.
"We're thrilled," said Angela Kohler, global media analyst with Federated Investors in Pittsburgh. "We expect the price could go higher."
Federated had said that $30 a share represents a fair-value price for Disney. Comcast's Roberts declined to speculate on how high the company would bid.
Comcast may have an edge in the negotiations. Steve Burke, a senior Comcast executive, worked at Disney for many years.
Kohler doesn't expect a third party to enter the fray and challenge Comcast as it tries to buy Disney. "But we've learned to expect originality in media deals," she said.
