Talx ( TALX) surged 8% late Thursday after setting a 3-for-2 stock split and reaffirming third-quarter guidance. The St. Louis-based company, which describes itself as a business process outsourcer of payroll data-centric services, said it expects its third-quarter profits to be "comfortably above" guidance of around 27 cents a share. The company expects to post revenue of more than $39 million, which is just above the top end of its previous range. "Revenues for The Work Number have exceeded our expectations for the quarter, primarily due to strong transaction levels across all segments of this business," said CEO William Canfield. "We expect revenue growth of nearly 50% compared to the same quarter last year." The company said the stock split would be payable Feb. 17 as a 50% stock dividend to holders of record Jan. 20. In after-hours action, Talx rose $1.86 to $25.
