Among the companies with shares expected to actively trade in Wednesday's session are Adobe Systems Inc. (ADBE), Tetra Tech Inc. (TTEK) and Pool Corp. (POOL).

Adobe's fiscal second-quarter earnings fell 66% on higher expenses as the company accelerated its transition to online subscription services and away from periodic releases of licensed and packaged software. Per-share earnings topped the company's expectations. Shares were up 7.9% to $46.77 premarket.

Tetra Tech expects to post a loss for the fiscal third quarter amid higher-than-expected restructuring costs related to its Eastern Canada and mining operations, as well as adverse findings regarding claims mostly related to change orders on some projects for certain U.S. federal and state government customers. Shares sank 12% to $23.50 premarket.

Pool lowered its 2013 earnings guidance as the wholesale distributor said cooler and unusually wet weather in its seasonal markets in North America and Europe led to later-than-usual pool openings and lower-than-expected sales. Shares were down 5.7% to $51.60 premarket.

J.P. Morgan initiated coverage of Keryx Biopharmaceuticals Inc. (KERX) with an overweight view and $13 price target, "based on the potential of Zerenex, its first-in-class, oral drug candidate for the treatment of hyperphosphatemia (elevated serum phosphorus) in dialysis patients." Shares rose 6.1% to $8.13 premarket.

Vivus Inc. (VVUS) said a study showed its erectile-dysfunction treatment Stendra enabled sexual activity within 15 minutes. Vivus said it plans to file for an amendment to both the U.S. Food and Drug Administration approval and the pending European Medicines Agency application to obtain new labeling regarding the shorter wait time. If approved, Stendra and Spedra, as it is known in the European Union, will be the only phosphodiesterase type 5 inhibitor to be able to make this claim, said Vivus. Shares rose 4.3% to $14.35 premarket.

Protalix BioTherapeutics Inc. (PLX) reached a supply and technology transfer deal with an arm of the Brazilian Ministry of Health for the company's Uplyso enzyme replacement therapy for the treatment of Gaucher disease. The Israel-based company's shares were up 7.3% to $5.45 premarket.

Biodel Inc. (BIOD) said it plans to offer common stock, but didn't disclose how many shares it intends to sell. The specialty biopharmaceutical company had 14.2 million shares outstanding as of May 10. Shares slipped 2.1% to $4.66 premarket.
