DivX ( DIVX) shares ballooned nearly 13% in after-hours trading Monday as the San Diego-based video-software developer boosted its first-quarter outlook. Pre-tax earnings are now forecast as flat to higher than last year, whereas prior guidance predicted a possible decline. Revenue will probably range between $19.8 million and $20.2 million, beating the $18.7 million mean estimate per Thomson Financial. Sales were previously expected at $17.3 million to $19.3 million. Shares were up $2.55 to $22.65 in recent late trading. Cascade ( CAE), which makes equipment primarily for the lift-truck industry, saw 27% higher profits year over year. Shares jumped to 80 cents, besting fiscal fourth-quarter street projections by a nickel. Revenue added 9.7% from last year to $118.9 million, just topping consensus. Shares of the Portland, Ore., company were gaining $1.25, or 2.1%, to $60.52. Gasco Energy ( GSX) sank after the Denver-based company announced it will offer 10 million of its shares. Proceeds will be used for general corporate purposes. Shares were down 32 cents, or 13.4%, to $2.07. Ciphergen Biosystems ( CIPH) dropped after auditors issued a going-concern warning for the Fremont, Calif., maker of proteomics-research equipment, citing "recurring losses and negative cash flows from operations and ... a net capital deficiency." Shares of the small-cap firm were falling 9 cents, or 6.7%, to $1.25. Valspar ( VAL) slid after the Minneapolis-based paint maker said profits for the quarter ended April 27 should be between 36 cents and 40 cents a share (excluding certain non-cash adjustments), or at least 9 cents shy of targets. Fiscal 2007 income should now fall to the low end of the company's prior range between $1.80 and $1.90 a share. Analysts are seeking $1.84 a share. Valspar stock was slipping $1.60, or 5.7%, to $26.50. Lawson Software ( LWSN) of St. Paul, Minn., swung to a GAAP-based fiscal third-quarter loss of $9.8 million, or a nickel a share, largely due to costs associated with its 2006 Intentia takeout. A year ago, the business-software company earned 9 cents a share. Non-GAAP results nonetheless beat estimates, but shares were receding 30 cents, or 3.4%, to $8.60, in recent after-hours action.
