Among the companies with shares expected to actively trading in Wednesday's session are Cisco Systems Inc. (CSCO), Envivio Inc. (ENVI), Mosaic Co. (MOS) and Woodward Inc. (WWD).

Cisco's fiscal first-quarter profit jumped 18% as the network-equipment maker continued to sell routers and switches profitably despite a slump in U.S. federal spending and ongoing weakness in Europe. The stronger-than-expected results sent shares up 7.5% to $18.12 after hours.

Envivio cut its current-quarter revenue guidance, saying softer spending by service providers has weakened demand for its video-networking technologies. Shares tumbled 18% to $1.54 after hours.

Mosaic cut its fiscal second-quarter potash and phosphates sales volume guidance, pointing to weakened demand in the international crop nutrient market, although the fertilizer producer believes the demand is simply delayed. Shares were off 5.1% at $48.16 in late trading.

Woodward's fiscal fourth-quarter profit rose 11% as the company reported strong aerospace sales and a late-year bump in the wind-turbine market before government incentives expire. Shares were up 3.3% at $33.11 after hours as earnings beat analysts' expectations.

Comstock Mining Inc. (LODE) is offering an undisclosed number of shares, as the gold and silver mining company looks to raise funds for working capital and general corporate purposes. Comstock had 43.6 million shares outstanding as of Nov. 13. Shares fell 7.5% to $2.11 after hours.

Navidea Biopharmaceuticals Inc. (NAVB) said the FDA will decide whether to approve its Lymphoma diagnostic tool by April 30. That's about six months from now, about how long analysts such as LifeTech Capital's Stephen Dunn had been expecting. Some investors were betting on a two-month review, and the stock was down 4.6% to $2.50 after hours.

Spectra Energy Partners LP (SEP) is offering about 4.8 million common units representing limited partner interests. The natural gas pipeline and storage facility operator had 96.4 million common units outstanding as of Sept. 30. Units slid 4.5% to $27.31 after hours.
