NEW YORK (MarketWatch) -- Shares of International Securities Exchange, the operator of an electronic options- and stock-trading platform, jumped 43% in early trading after the company confirmed it was in advanced talks with Germany's Deutsche Boerse about a takeover.

Deutsche Boerse said it is negotiating to buy the company for $67.50 a share, or about $2.8 billion. The ISE said in a statement that the deal is subject to negotiation of final terms and must be approved by the company's board.

ISE share rallied $19.59, or 43%, to $65.31 in trading after the opening bell.

The purchase would give Deutsche Boerse, which already owns a share of the Eurex electronic derivatives exchange, a foothold in the rapidly growing U.S. options business.

Deutsche Boerse said it would acquire ISE through Eurex.

"The executive board of Deutsche Börse AG has resolved to recommend the transaction to its supervisory board for approval. The supervisory board of Deutsche Börse AG, the supervisory board of SWX and the ISE board of directors shall decide on the transaction today," the company said in a news release.

The SWX, the Swiss Exchange, is Deutsche Boerse's partner in Eurex.

The deal would mark the latest milestone in the rapid cross-border consolidation of the exchange industry as technology reshapes markets in all sorts of financial instruments.

Earlier this month, ISE reported first-quarter net income of 42 cents a share, slightly below Wall Street expectations, but said that options volume rose 15% from the previous quarter and 16% from the year-earlier period.

Shares of Deutsche Boerse rose 1.3% in European trading Monday.
