Redwood City, Calif.--Blaming the weak advertising market, broadband delivery network Excite@Home Corp. said its first-quarter revenues will be significantly lower than expected. Excite@Home said it expects to report revenues of $140 million to $145 million for the first quarter, compared with $138 million in the first quarter of 2000. It expects to report a loss per share in the range of 14 to 15 cents, compared to a loss of 1 cent per share in the first quarter of 2000. The company said it will continue to focus its strategy around its broadband business through the potential sale of media operations not directly supporting broadband. Excite@Hme will release its first-quarter earnings report on April 23.
