• AT&T workers in Southeast ratify union contract

DALLAS — AT&T Inc. (NYSE: T) said Friday that its employees approved a new three-year contract covering about 30,000 workers in the Southeast.

The new pact calls for pay and pension increases over the next three years and cash payments tied to the company’s financial performance but also higher health care premiums.

The deal covers workers in the Communications Workers of America’s District 3, which includes Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina and Tennessee.

• S1 Corp. 4Q profit up 86 percent

NORCROSS, Ga. — Financial-services software provider S1 Corp. (Nasdaq: SONE) said Friday profit for the fourth quarter rose 86 percent as revenue improved and expenses fell.

The company reported net income of $9.9 million, or 18 cents per share, compared with $5.3 million, or 10 cents per share, a year earlier.

Revenue rose to $59.5 million from $58.6 million a year ago, due to higher sales in the support and maintenance division. Software license, professional services and data center revenue slipped lower. Expenses fell to $50.7 million from $54.4 million.

For the year, the Norcross, Ga.-based company said it earned $30.4 million, or 55 cents per share, compared with $21.9 million, or 38 cents per share, in 2008. Revenue increased 5 percent to $238.9 million from $228.4 million.

The company completed on March 4 the $28.9 million acquisition of PM Systems Corp., a provider of internet banking, bill pay and security products for U.S. credit unions. The deal was funded from available cash. PM Systems is expected to generate $9.6 million, in revenue net of transaction costs and other adjustments, this year.

Revenue for the year, including the PM Systems acquisition effect, is expected to be in the range of $248 million to $254 million, and earnings per share are expected to be between 51 cents and 57 cents.

CEO Johann Dreyer said market conditions will remain challenging, but global sales opportunities are expected to improve, specifically in payments and cash management products.

• HP trims 1Q net income because of lawsuit ruling

PALO ALTO, Calif. — Hewlett-Packard Co. (NYSE: HP) trimmed the net income it reported for its fiscal first quarter Friday, saying it has to set aside more money than expected to deal with a lawsuit against it in the U.K.

HP, the world’s biggest computer maker, now says it earned $2.25 billion, or 93 cents per share, in the three months ended in January. That’s down from the $2.32 billion, or 96 cents per share, it reported last month.

HP said the revision was prompted by a ruling that could force subsidiary Electronic Data Systems to pay out another $112 million to the U.K.’s British Sky Broadcasting Group PLC. EDS, which HP acquired in 2008, had already made a voluntary payment in the case of $320 million, the company said. BSkyB filed suit against EDS, a technology services provider, in 2004 over a dispute related to a customer management contract.

HP said it is looking to appeal the ruling.
