AeroVironment, Inc. Announces Fiscal 2011 Second Quarter Results

MONROVIA, CA, December 7, 2010 — AeroVironment, Inc. (AV) (NASDAQ: AVAV) today reported financial results for its second quarter ended October 30, 2010.

“Strong execution produced second quarter performance that exceeded our forecast, keeping us on track for our fiscal year 2011 plan. Key development programs also hit important milestones in the quarter that move them closer to market adoption,” said Tim Conver, AV chairman and chief executive officer.  “We received significant orders for digital Puma small unmanned aircraft systems and made deliveries earlier than expected. We also began the rollout of electric vehicle charging infrastructure, demonstrating progress in two key growth areas for fiscal 2011.  Additionally, we made great progress on the Global Observer Joint Capability Technology Demonstration program with the successful completion of initial flight testing.  I believe that we are well on our way to achieving our annual performance targets and positioning AV for long-term growth.”

FISCAL 2011 SECOND QUARTER RESULTS

Revenue for the second quarter of fiscal 2011 was $63.8 million, up 24% from second quarter fiscal 2010 revenue of $51.4 million. The increase in revenue resulted from higher sales in our Unmanned Aircraft Systems (UAS) segment of $9.9 million and Efficient Energy Systems (EES) segment of $2.5 million.

Income from operations for the second quarter of fiscal 2011 was $0.4 million, down 88% from second quarter fiscal 2010 income from operations of $3.4 million. The decrease in income from operations was caused by higher selling, general and administrative (SG&A) expense of $2.2 million and higher research and development (R&D) expense of $2.9 million, partially offset by higher gross margin of $2.1 million.

Net income for the second quarter of fiscal 2011 was $0.3 million, down 88% from second quarter fiscal 2010 net income of $2.2 million.

Earnings per diluted share for the second quarter of fiscal 2011was $0.01, down 90% from second quarter fiscal 2010 earnings per diluted share of $0.10.

Revenue for the first six months of fiscal 2011 was $102.0 million, up 14% from the first six months of fiscal 2010 revenue of $89.3 million. The increase in revenue resulted from higher sales in our UAS segment of $10.1 million and EES segment of $2.6 million.

Loss from operations for the first six months of fiscal 2011 was $6.9 million, up 232% from the first six months of fiscal 2010 loss from operations of $2.1 million. The increase in loss from operations was caused by higher SG&A expense of $3.1 million and higher R&D expense of $5.2 million, partially offset by higher gross margin of $3.4 million.

Net loss for the first six months of fiscal 2011 was $3.2 million, up 132% from the first six months of fiscal 2010 net loss of $1.4 million.
