Flash-based storage solutions vendor Fusion-io announced it has filed papers with the SEC purposing a public offering of its stock. The company went public not too long ago and already it’s looking to sell about $350 million worth of its shares, of which $100 million will be offered by Fusion-io and the rest by existing shareholders according to documents.

The company revealed some details in a press release that went out this morning.

“Fusion-io is proposing to sell approximately $100 million of its shares. The remaining shares will be sold by existing stockholders, including any shares issued to the underwriters to cover over-allotments.

Goldman, Sachs & Co. and Morgan Stanley & Co. LLC are acting as lead joint book-runners for the proposed offering, and J.P. Morgan Securities LLC and Credit Suisse Securities (USA) LLC are acting as joint book-runners.”

Fusion-io managed to grow exponentially thanks to its hardware and software storage acceleration products, and the company’s shares are catching to this performance. It’s earnings in the first quarter of fiscal year 2012 didn’t disappoint shareholders: Fusion-io reported a 175 growth in GAAP revenue alongside a significant boost to its net profit. Its non-GAAP figures have also improved, seeing a rise in revenue from a net loss of $4.9 million a year earlier to $15.1 million.

This latest earnings call represented the second the storage vendor ever held since its going public, which is why it was naturally monitored by analysts and investors. The positive results helped put some more validation into Barron’s decision to select FIO as the stock of the year (beating Apple, Oracle, EA and several others to it) shortly before the call. This view, along with an equally optimistic forecast managed to lift Fusion’s shares by over 20 percent.
