Analyst · BWS Financial
Thank you, and good afternoon. Before we get started, let me take a moment to read our Safe Harbor statement.
During this call, we will make statements that are forward-looking. These forward-looking statements involve risk and uncertainties, including but not limited to, stated expectations relating to revenue from our new and mature products, statements pertaining to our design activity and our ability to convert new design opportunities into customer activity, market acceptance of our customer products, our expected results and our financial expectations for revenue, gross margin, operating expenses, profitability and cash.
QuickLogic's future results could differ materially from the results described in these forward-looking statements. We refer you to the risk factors listed in our annual report on Form 10-K, quarterly reports on Form 10-Q and prior press releases for a description of these and other risk factors. QuickLogic assumes no obligation to update any such forward-looking statements. This conference call is open to all and is being webcast live.
For the first quarter of 2012, total revenue was $4.1 million, which was just below the midpoint of our guidance of $4.2 million. New product revenue totaled $1.6 million, which was down slightly from the Q4 level, but was near the high point of our guidance. Mature product revenue in the quarter totaled $2.5 million, which represents a 6% sequential decrease from Q4. Mature product revenue continues to be negatively impacted by lower bookings from our customers in the aerospace, test and instrumentation sectors.
Our non-GAAP gross profit margin for Q1 was 43% and was below the low end of our guidance. At the end of the quarter, we booked an inventory reserve of approximately $329,000 or 8% of revenue. The majority of this reserve was for mature products and was due to a lower bookings rate. Non-GAAP operating expenses for Q1 totaled $5.1 million. The increase in expenses over Q4 was primarily due to an increase in engineering expenses related to our new platform development program. These expenses should decline in the second quarter. On a non-GAAP basis, other income and expenses and taxes for Q1 were net positive totaling approximately $19,000. This resulted in a non-GAAP loss of $3.3 million or $0.09 per share.
We ended the quarter with approximately $17.2 million in cash. Cash decreased during the quarter by $3 million, which was consistent with our guidance. Our Q1 GAAP net loss was $3.7 million or $0.10 per share. Our GAAP results included stock-based compensation charges of $384,000. Please see today's press release for a detailed reconciliation of our GAAP to non-GAAP results.
Now I'll turn it over to Andy, who'll update you on the status of our strategic efforts. Following this, I'll rejoin the call to present our Q2 guidance.
