Cash, cash equivalents and marketable securities were $7.7 million at March 31, 2014, down $6.1 million from $13.8 million at June 30, 2013. The decrease in cash is primarily due to repurchasing inventory back in-house from our previously outsourced manufacturing contractor, severance due to reduction of headcount and operating losses.

“Qualstar has attained significant reductions in operating expenses as we continue to streamline our processes – including bringing manufacturing back under our own direction to improve speed of delivery and quality. By balancing the aggressive moves to reduce costs and investment in expanding our product portfolio to target new, growing markets, we are well-positioned to realize growth as a company,” stated Mr. Steven N. Bronson, Qualstar’s Chief Executive Officer.

“Our strategy remains focused on driving improved performance that will keep us leaders of data storage solutions,” stated Mr. Bronson.
