Among the companies with shares actively trading premarket Wednesday are Staples Inc. (SPLS), Deere & Co. (DE) and JDS Uniphase Corp. (JDSU).

Staples posted a 32% slump in profit in its latest quarter, hurt by an unexpected downturn in North American sales trends and continued sluggishness abroad. The nation's largest office supply chain also lowered its full-year guidance, sending shares tumbling 13% to $11.69 in premarket trading.

Deere's fiscal third-quarter earnings rose a less-than-expected 11% as sales came under pressure from weaker international demand and short-term manufacturing issues. Shares dropped 5% to $76.09 in premarket trading after Deere also cut its view for the year. Fellow machinery maker Caterpillar Inc. (CAT) also traded lower, shedding 1.6% to $86.51.

JDS Uniphase swung to a fiscal fourth-quarter loss as the broadband-products maker saw shrinking revenue from its core business segments, and said its chief financial officer has resigned. However, adjusted profits beat analyst estimates while revenue topped the company's expectations. Shares rose 5.1% to $11.21 premarket.

Physicians Formula Holdings Inc. (FACE) agreed to be taken private in a deal valuing the cosmetics and skin care company at roughly $58 million.

Shares jumped 14% to $4.20 in premarket trading.

Greif Inc. (GEF) cut its full-year earnings guidance, citing lower than expected third-quarter volumes for its rigid industrial packaging and flexible products businesses. Shares fell 5.3% to $41 premarket.

KIT digital Inc.'s (KITD) second-quarter loss widened sharply as the video-management software company worked to undertake a business transformation. Results missed analyst expectations. Shares were off 6.7% to $2.80 premarket.

Canadian Solar Inc. (CSIQ) swung to a second-quarter loss as lower selling prices continued to dampen results from the solar panel and equipment maker. Shares tumbled 13% to $2.64 premarket.

Ellington Financial LLC (EFC) has commenced an offering of 3.5 million shares representing limited liability company interests. The specialty finance company plans to use the proceeds to buy its targeted assets, including prime and subprime mortgage-backed securities. Shares were off 4.5% to $22.35 premarket.

TICC Capital Corp. (TICC) said it is offering 2 million shares as the company seeks to raise money for general purposes, which may include investing in corporate debt and equity, and in structured finance vehicles. Shares of TICC Capital, which provides funding to tech companies, slipped 2.6% to $9.65 premarket.
