SIMI VALLEY, Calif., June 13, 2013 — Qualstar Corporation (NasdaqGM: QBAK), a manufacturer of data storage solutions and high-efficiency power supplies, today announced that, in connection with management’s upcoming meetings with investors, it has filed its latest investor presentation with the Securities and Exchange Commission.

The company will hold a conference call on Wednesday, June 19, 2013 at 2 p.m. PT (5 p.m. Eastern) to discuss this presentation and take questions. All shareholders are encouraged to participate by dialing (800) 935-0893 or (847) 944-7376 and providing the passcode 35097942, or via the Internet using the link under the “Investors” section at www.qualstar.com.

In the investor presentation, Qualstar reviews the significant progress its new management team and independent board have made implementing the strategic plan that it announced in June 2012. By executing this plan, Qualstar is transforming its model from a high overhead, low margin, manufacturing-based company, to a highly scalable, high margin, low overhead, variable cost business that is positioned to expand its presence in both the storage and power supply markets. This is creating a platform for long-term growth, sustainable profitability, positive cash flow and increasing returns for investors. Qualstar also details in the investor presentation why shareholders should reject the latest attempt by BKF Capital Group, Inc., a publicly-held shell company controlled by Steven N. Bronson, to seek control of Qualstar without paying shareholders an appropriate control premium. Shareholders may obtain a copy of the investor presentation for free at the SEC’s website at http://www.sec.gov or under the “Investors” section on Qualstar’s website at http://www.qualstar.com.

“Over the next few weeks, I plan to meet with many of our shareholders, large and small, and share with them the progress we have made in implementing our strategic turnaround plan and transforming Qualstar for long-term growth, sustainable profitability, positive cash flow and increasing returns for investors,” said Lawrence D. Firestone, Qualstar’s President and Chief Executive Officer. “For close to 30 years, Bill Gervais, the founder of Qualstar, created innovative and technologically superior products that stood for quality and reliability in both the data storage and power conversion markets we serve. As we move forward with our transformation and strategic plan, we are proud of our accomplishments and excited by the opportunities now available to us as a streamlined sales and product development organization positioned for profitability and growth.”
