Updated from Aug. 1Shares of Walt Disney ( DIS) plunged Friday after the company warned investors that lingering weakness in its theme park business will pressure its current quarter. The warning came Thursday night and was followed by a slew of brokerages lowering their price targets. Recently the stock was down 11% to $15. The media conglomerate also announced its support for various new measures related to governance and financial reporting, including recognizing stock options as an operating expense. Following Disney's after-hours release of financials, its shares dropped $1.30 to $15.53, worsening a 90-cent loss in normal trading. Beset by economic weakness and a vacation travel slowdown stemming from last September's terrorist attacks, Disney's shares are down 44% from their 52-week high. For the fiscal third quarter ended June 30, Disney's revenue fell to $5.8 billion, down 6% from pro forma figures for the corresponding quarter one year earlier and shy of the Thomson Financial/First Call consensus of $5.86 billion. Net income of $364 million, or 18 cents per share, was down from the pro forma figure of $527 million, or 25 cents per share, in the third quarter of fiscal 2001. Analysts had expected a 17-cent profit. Disney said attendance and advance reservations in the fourth quarter were soft, and the company expects that fourth-quarter earnings will drop from pro forma figures for 2001.
