RAE Systems Reports Third Quarter 2009 Results
- - Achieves Non-GAAP Profitability -
- - Books an Accrual for Potential FCPA Settlement with DOJ & SEC —

SAN JOSE, Calif. — November 4, 2009 —RAE Systems Inc. (NYSE AMEX: RAE), a leader in delivering innovative sensor solutions to serve industrial, energy, environmental, and government safety markets worldwide, reported financial results and business highlights for the third quarter ended September 30, 2009.

Financial Results

For the third quarter of 2009, RAE Systems reported revenue of $19.9 million, compared with
$19.9 million in the second quarter of 2009 and $28.8 million in the third quarter of 2008. The year-over-year decrease is primarily attributable to the global recession, two significant non-recurring orders recorded in third quarter of 2008, and a disruption of sales activity in China due to recent management changes. For the third quarter of 2009, the Americas contributed 46 percent of total revenue, Asia contributed 37 percent and Europe contributed 17 percent of revenue. Gross margin for the third quarter was 52 percent, compared with 50 percent for the second quarter 2009 and 55 percent for the third quarter of 2008. Operating expenses for the third quarter 2009 were $14.2 million, compared with $14.4 million for the third quarter of 2008.

The company is actively engaged in discussions with the Department of Justice and the Securities and Exchange Commission to settle the outstanding joint investigation into the company’s alleged violations of the Foreign Corrupt Practices Act (FCPA). Although no assurances can be given as to whether the matter will settle or the amount of any settlement, the company booked an accrual of $3.5 million in the third quarter 2009 relating to this potential settlement.

The third quarter 2009 GAAP net loss was $3.5 million, or $0.06 per share. Excluding the impact of the reserve for the potential FCPA settlement, non-GAAP net income was $11,000 or $0.00 per share. These compare with third quarter 2008 net income of $554,000 or $0.01 per share.

For the nine months ended September 30, 2009, revenue was $58.9 million, compared with $71.4 million for the same period in 2008. For the nine months ended September 30, 2009, the GAAP net loss was $6.7 million or $0.11 per share and the non-GAAP net loss was $3.2 million or $0.05 per share. This compares with a net loss of $2.2 million or $0.04 per share for the same period in 2008.

“During the quarter, to ensure our long-term success, we furthered initiatives to run the company more efficiently, particularly in China,” said Robert Chen, president and CEO of RAE Systems. “Globally, we are prioritizing cost management, business controls and cash generation. For the nine months ended September 30, 2009, we increased our cash balance by $1.3 million to $16.2 million. In China, we installed a new management team; instituted mandatory, ongoing, FCPA compliance training; and began consolidating certain operations.”

“Due to the continued uncertainty of the worldwide economic outlook for 2009 combined with year-to-date performance, we now expect full year 2009 revenue of between $80.0 million and $82.0 million, and we do not expect to be profitable for the year,” Chen concluded.
