• Qualstar Received New Orders for Data Storage Products in September 2014 Exceeding $1.1 Million

SIMI VALLEY, Calif., September 29, 2014 — Qualstar® Corporation (NASDAQ: QBAK), a manufacturer of data storage solutions and high-efficiency power supplies, today reported financial results for the fourth quarter and the fiscal year ended June 30, 2014.

Fiscal 2014 Fourth Quarter Financial Results

Revenues for the quarter ended June 30, 2014 were $2.7 million, compared with $2.9 million for the quarter ended June 30, 2013, a decrease of $0.2 million or 5%. Loss from operations was $0.7 million for the quarter ended June 30, 2014 compared with a loss of $3.5 million for the quarter ended June 30, 2013. Loss per share was $(0.06) for the quarter ended June 30, 2014 compared with loss per share of $(0.28) per basic and diluted share for the quarter ended June 30, 2013.

“If you look at net losses without the inventory adjustments (non-GAAP), taken in the fourth quarters of 2014 and 2013, our net loss is $0.4 million, or $(0.03) per share, versus a loss of $2.8 million or $(0.23) per share, in 2013, a substantial improvement,” said Steven N. Bronson, Qualstar’s Chief Executive Officer. “Furthermore, our annual break-even revenue run rate is approximately $13 million, substantially lower compared to a year ago.”

Data Storage segment revenues were $1.2 million for the quarter ended June 30, 2014, compared with $1.1 million for the same period last year, an increase of $0.1 million or 6%. Power supply segment revenues were $1.5 million for the quarter, compared with $1.7 million in the quarter ended June 30, 2013, a decrease of $0.2 million, or 11%.

“Qualstar’s loyal resellers and new partners from around the world have shown their enthusiastic endorsement of the new and refreshed product lines and are experiencing first-hand the renewed vitality and vigor of Qualstar as we support and enable our channel partners to be successful,” stated Daniel K. Jan, Qualstar’s Executive Vice President.

Gross margin was 30% of revenues or $820,000, for the quarter ended June 30, 2014, an improvement over the gross margin of 12% of revenues or $370,000 for the quarter ended June 30, 2013. The increase in gross profit was primarily attributed to lower charges to the inventory reserves during the quarter. Engineering expenses for the fourth quarter of the fiscal year 2014 were $482,000, or 18% of revenues, compared with $1.0 million, or 36% of revenues for the fourth quarter of the fiscal year 2013.

Restructuring expenses for the fourth quarter of fiscal 2014 were $(0.2) million or 8% of revenues, compared to $0.4 million, or 12% of revenues, for the same period last year.

Fiscal 2014 Full Year Financial Results

Qualstar reported revenues of $10.9 million in the fiscal year 2014, a decrease of 13% compared with $12.6 million in the fiscal year 2013. Net loss in fiscal 2014 was $5.6 million or $(0.46) per basic and diluted share. This compares with a net loss in the fiscal year 2013 of $10.4 million, or $(0.85) per basic and diluted share.

Cash equivalents and marketable securities were $7.2 million at June 30, 2014, compared with $13.8 million at June 30, 2013, down $6.6 million. Inventory, net of reserves, at June 30, 2014, was $3.2 million, compared with $1.6 million at June 30, 2013. This increase in inventory is primarily attributable to the inventory buyback from our former contract manufacturer.

“Qualstar’s fiscal 2014 accomplishments are a direct result of streamlining our core business structure and decision-making processes as ‘One Qualstar’. By recruiting seasoned executives and building a proactive in-house marketing team, we continue to strategically reinforce and improve Qualstar’s overall business management,” stated Mr. Bronson. “In addition to the release of mediaExeQ™, Q24™ and RVA® storage solutions, we plan to continue to expand our product portfolio and optimize the growth of our business over time. We’ve already started off our new fiscal year favorably by adding two series to our power supply product line, Medical and DIN Rail.”

“We received multiple orders for our RLS Tape libraries from an Asian government agency and we received two orders for our XLS Enterprise tape library from a corporate customer in Mexico. These orders represented a majority of the $1.1 million in data storage product sales orders received in the month of September 2014,” added Mr. Bronson.
