* Broderbund Software Inc. said its fiscal second-quarter earnings rose 21%, propelled by sales of its "Riven" fantasy game and its Carmen Sandiego educational software products. The Novato, Calif.-based education and entertainment software maker reported net income of $3.88 million, or 18 cents a diluted share, compared with profit before a charge of $3.2 million, or 15 cents, a year earlier. Revenue rose 77% to $78.6 million from $44.3 million. Per-share earnings were a penny below analysts' estimates. Shares were unchanged at $23.88 on Nasdaq.
* San Jose-based Komag Inc. said a glut of disk drives will push sales down by as much as 55% in its fiscal first quarter, leading to a larger-than-expected loss, the company's second warning for the quarter. Komag, which makes disk drive components, said in January that sales would fall 40% from the $159.0 million reported for the fiscal fourth quarter ended Dec. 28. Komag has suffered as the supply of disk drives outpaces demand and consumers flock to cheaper, less-powerful personal computers. Before Wednesday's warning, Komag was expected to lose 53 cents per share. The warning was issued after close of U.S. trading.
* Alameda, Calif.-based Ascend Communications Inc. shares rose 4% after the company said it signed a contract with British Telecommunications and expects to sell more networking equipment to the telecom giant. Ascend shares rose $1.44 to close at $36.25 on Nasdaq.
