Among the companies with shares expected to actively trade in Friday's session are F5 Networks Inc. (FFIV), WD-40 Co. (WDFC) and Exide Technologies Inc. (XIDE).

Network-gear maker F5 Networks slashed its view of fiscal second-quarter results after business from customers in North America arrived below expectations. Shares tumbled 16% to $76.10 after hours.

(RVBD) shares were off 3.3% at $14.46, and Cisco Systems Inc. (CSCO) shares fell 2.6% to $20.50.

WD-40's fiscal second-quarter profit fell 1.2% as the maintenance and cleaning products company's weaker Americas sales and higher expenses masked improvements in the Europe and Asia-Pacific regions. Shares rose 7.5% after hours to $56.78 as the company beat earnings expectations and raised its income outlook for the year.

Exide has retained an adviser to review financing options to maximize value for the battery manufacturer's shareholders. Shares surged 23% to $1.69 after hours.

Latin American wireless operator NII Holdings Inc. (NIHD) has agreed to sell its Peruvian operations to Empresa Nacional de Telecomunicaciones S.A. (ENTEL.SN) for around $400 million as it narrows its focus to Mexico and Brazil. Shares rose 7.9% in after-hours trading to $4.90.

Valero Energy Corp.'s (VLO) board has approved the spinoff of its retail business, a move that comes as the company reshuffles its portfolio. Shares were up 3.7% at $42.98 after hours.
