MarketWatch.com Chief Commentator, Thom Calandra, Resigns

SAN FRANCISCO--(BUSINESS WIRE)--Jan. 22, 2004--MarketWatch.com, Inc. (NASDAQ:MKTW), a leading multimedia publisher of business news and provider of financial information and analytical tools, announced today that its chief commentator and author of The Calandra Report, Thom Calandra, has resigned for personal reasons.

The U.S. Securities and Exchange Commission (SEC) has commenced an informal inquiry into Mr. Calandra's trading activities dating back to October 2002. Upon being notified of the inquiry by Mr. Calandra in December 2003, MarketWatch began conducting its own internal investigation into whether Mr. Calandra violated the Company's trading and disclosure policies. The Company's internal investigation is ongoing.

“We have a responsibility to our readers and subscribers to cooperate with the SEC in its determination of whether or not Thom violated these policies.”

"We regret Thom Calandra's departure from the Company. While we have made a very clear distinction that Thom provides commentary and opinion in his newsletter and does not report business news, Thom was required to abide by our internal trading policies and fully disclose his activities to his readers and subscribers," said Larry Kramer, MarketWatch's chairman and CEO. "We have a responsibility to our readers and subscribers to cooperate with the SEC in its determination of whether or not Thom violated these policies."

In connection with the SEC's informal inquiry, MarketWatch has received a request from the SEC to produce voluntarily documents and other relevant information concerning these matters. MarketWatch is cooperating fully with the inquiry.

Mr. Calandra's newsletter, The Calandra Report, has been terminated and subscribers will be given pro-rated refunds. All subscribers are being notified directly by the Company today.
