Friday's Small-Cap Winners & Losers

Buyout news sharply lifted Smithway Motor Xpress (SMXC Quote) Friday after privately held Western Express agreed to buy the trucking company for some $54 million, or roughly $90 million including debt acquisition. Shareholders will receive $10.63 a share in cash. The transaction should close this summer. Shares of Iowa-based Smithway were trading up $1.35, or 15%, to $10.35.

Power-One (PWER Quote), maker of power-conversion products, gained after announcing a favorable ruling from pre-jury-trial hearings in its patent-infringement suit against Artesyn Technologies, a unit of Emerson Electric (EMR Quote). The U.S. District Court for the Eastern District of Texas rejected Artesyn's contention that the patents in question are indefinite and, therefore, invalid.

Power-One also said the court also accepted "a significant majority" of its definitions of contested terms. The jury trial is scheduled to begin in August. California-based Power-One was climbing 65 cents, or 11.5%, to $6.31. Artesyn's parent Emerson Electric was recently adding a penny to $43.86.

Hoku Scientific (HOKU Quote) got a lift after it secured 67 acres of land in Idaho for planned construction of a polysilicon-production plant capable of churning out 2,000 metric tons of the compound per year. The Hawaii-based maker of clean-energy technologies signed a 99-year, virtually free ($1 annually) lease with the City of Pocatello for the land, and has the option to lease another 450 acres for future expansion, the terms of which would be subject to further negotiation. Shares were rising 49 cents, or 9.2%, to $5.80.

Multimedia Games (MGAM Quote) was higher after the Austin, Texas-based company said it secured a $150 million five-year revolving credit line -- double the funds available from its existing one. The new facility will replace the old one in mid-April. Shares were up 92 cents, or 8.1%, to $12.24.
