Among the companies with shares expected to actively trade in Thursday's session are NetApp Inc. (NTAP), Diamond Foods Inc. (DMND) and PetSmart Inc. (PETM).

NetApp posted a smaller-than-feared drop in quarterly earnings as revenue improved even in hard-hit Europe, suggesting the data-storage maker's top line may be poised to reaccelerate. Its current-quarter projections also came in better than expected. Shares jumped 10% to $29.89 after hours.

Diamond Foods said it closed the book on the walnut-accounting scandal that dogged the maker of snack foods during the past year, but opened a new chapter of struggles related to securing enough walnuts for its business and righting some of its other businesses. Diamond late Wednesday disclosed restated financial results tied to the accounting scandal and showed that it swung to a loss during the first three quarters of 2012 as it took significant charges related to its investigation. Shares slmped 18% to $16 after hours.

PetSmart's fiscal third-quarter profit grew a better-than-expected 47%, as the specialty pet store's same-store sales and margins continued to improve. Shares rose 6% to $68.75 after hours after the company again raised its earnings guidance for the year.

AspenBio Pharma Inc. (APPY) unveiled plans to offer common stock, but didn't detail how many shares it is selling. The diagnostic-product developer plans to use proceeds for general corporate purposes, including conducting a clinical trial for its blood-based appendicitis test, and for working capital purposes. It had 7.7 million shares outstanding as of Nov. 6. Shares slipped 16% to $2.06 after hours.

DryShips Inc. (DRYS) swung to a worse-than-expected third-quarter loss as the dry bulk shipper saw sharply higher drilling rigs operating expenses, masking modest revenue growth. Shares sank 8.7% to $1.90 after hours.

Velti PLC (VELT) swung to a third-quarter loss on heavy one-off expenses and operating costs, masking an increase in revenue. Shares plummeted 23% to $5.11 as the bottom-line results sharply missed Street expectations.
