B2B outfit



reported a narrower fourth-quarter loss on Wednesday, but its revenue fell from a year ago. The company provided first-quarter guidance in line with Wall Street estimates.

Using generally accepted accounting principles, Ariba reported a loss of $142.5 million, or 54 cents a share, compared with a loss of $224.3 million, or 89 cents a share, in the year-ago period. Revenue fell to $58.2 million from $62.6 million a year ago, amid a weak tech spending environment.

On the news, shares of Ariba were lately trading down 38 cents, or 16.7%, at $2.05.

Pro forma earnings were $5 million, or 2 cents a share, vs. a loss of $27.7 million, or 11 cents a share, a year ago. On that basis, Ariba beat estimates of a penny a share, according to Thomson Financial/First Call.

Ariba's pro forma earnings exclude certain noncash and special charges. They also keep out expenses of amortization of goodwill and other intangible assets, as well as stock-based compensation.

Ariba CFO Jim Frankola said Ariba expects first-quarter revenue to be flat to slightly up sequentially and pro forma earnings to be in the range of about 1 cents to 2 cents a share.

Wall Street analysts had projected first-quarter earnings of a penny a share on revenue of $58.8 million.

Frankola noted in an interview after the company's earnings were released that like other software companies, Ariba suffered a significant drop in revenue from 2001 to 2002 -- of about $180 million. But due to a restructuring, the company's pro forma income increased by $90 million over the same period.

The once high-flying business-to-business software maker has launched new spending management products that help companies not only create an auction to buy products and services but also structure the entire procurement transaction.
