NEW YORK, June 12 (Reuters Breakingviews) - Nasdaq (NDAQ.O) is catapulting itself into the future - but paying yesterday’s high prices to get there. She pursued this one with gusto, though: Adenza wasn’t for sale when Nasdaq started wooing Thoma Bravo, say people familiar with the situation. Little wonder Nasdaq shares plunged over 10% on Monday. The U.S.-based exchange operator would pay just under $5.8 billion in cash and the rest in new Nasdaq shares, leaving Thoma Bravo with a 14.9% stake. Nasdaq shares had fallen 9.4% by 10.00am EST on June 12.
