OCZ Technology Group, Inc. Reports Results for its Second Quarter of Fiscal 2014

SAN JOSE, Calif., October 15, 2013 (Marketwired) — OCZ Technology Group, Inc. (Nasdaq: OCZ), a leading provider of high-performance solid-state drives (SSDs) for computing devices and systems, reports its second quarter (Q2’14) results which ended on August 31, 2013.

“Revenue and gross margins declined in the second quarter as revenue for our client SSD products continued to be impacted by our challenges in procuring flash. Revenue from our enterprise solutions accounted for roughly half of our SSD revenue, compared to about 60% in the first quarter, as a major data center customer completed its installation during the quarter,” said Ralph Schmitt, CEO of OCZ Technology. “This has been a difficult quarter as demand for our products continues to be greater than our ability to supply, given our capital constraints.”

“Over the course of the quarter we continued to add strategic channel partners that help extend the reach of both our high-end client products and enterprise solutions worldwide. During the second fiscal quarter we also announced the general availability of our PCIe-based ZD-XL SQL accelerator which is a new way for OCZ to go to market with a total solution consisting of both our enterprise solid state storage and virtualization software. This innovative product is primarily targeted at our channel partners and offers an optimized plug-and-play storage system solution for enterprise customers,” added Schmitt.

Revenue for the second quarter of 2014 was $33.5 million compared to revenue of $55.3 million for the first quarter of 2014 and revenue of $88.6 million for the second quarter of 2013.

Gross margin for the second quarter of 2014 was 4.2% compared to a gross margin of 14.7% for the first quarter of 2014 and a gross margin loss of (4.6%) for the second quarter of 2013. Gross margins declined on a sequential basis primarily due to increased costs and decreasing sales prices in our mainstream client business. Enterprise margins remained consistent in the quarter.

Operating expenses for the second quarter of 2014 were $20.5 million, compared to operating expenses of $19.7 million for the first quarter of 2014 and operating expenses of $26.6 million for the second quarter of 2013. Operating expenses for the second quarter of 2014 include restatement related expenses of $3.4 million compared to $1.7 million in the first quarter of 2014.

Cash and cash equivalents at the end of second quarter of 2014 were $10.6 million compared to $5.0 million at the end of the first quarter of 2014. The increase in cash primarily reflects the issuance of $13.1 million of convertible debentures partially offset by cash used to finance our on-going operations.

Business Outlook and Commentary:

“Due to uncertainties in being able to procure forecasted flash amounts and credit constraints, we will not be providing guidance for the fiscal third quarter of 2014, ending November 30, 2013. It is our belief that at this point we cannot accurately predict the outcome of our efforts to resolve these issues,” stated Schmitt. “We continue to engage with interested parties in the various strategic options available to the Company, including additional financing initiatives and strategic alternatives and plan on providing an update to discuss progress regarding flash availability, credit, and our strategic activities when appropriate.”

Non-GAAP Financial Measures

OCZ continues to provide all information required in accordance with GAAP, but believes evaluating its ongoing financial results may not be as useful if an investor is limited to reviewing only GAAP financial measures. Accordingly, OCZ uses non-GAAP financial information to evaluate its ongoing operations and for internal planning and forecasting purposes. OCZ’s management does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. OCZ presents such non-GAAP financial measures in reporting its financial results to provide investors with an additional tool to evaluate OCZ’s financial results in a manner that focuses on what OCZ believes to be its ongoing business operations.

OCZ’s management believes it is useful for itself and investors to review, as applicable, both GAAP information and the non-GAAP measures in order to assess the performance of OCZ’s business and for planning and forecasting in subsequent periods. Whenever OCZ uses such a non-GAAP financial measure, it provides a reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures as detailed above.
