AMERIGON REPORTS SECOND QUARTER, SIX-MONTH RESULTS

Strong Year-over-Year Bottom-Line Improvement for Both Periods

DEARBORN, MI (August 4, 2004) . . . Amerigon Incorporated (Nasdaq:ARGN) today reported a significant improvement in bottom-line results for the second quarter and six months ended June 30, 2004 when compared with the prior year periods. President and Chief Executive Officer Daniel R. Coker said that in addition to achieving year-over-year gains in profit during the quarter, the Company continued its focus on increasing the penetration of its patented Climate Control Seat^™ (CCS^™) systems to automotive and seat manufacturers worldwide and on achieving its first full year of profitability in 2004.

Revenues for the 2004 second quarter increased 53 percent to $8.6 million, up from $5.6 million for the year-earlier period. Net income in this year’s second quarter improved to $295,000, or $0.02 per basic share and $0.01 per fully diluted share, compared with a net loss of $609,000, or a $0.06 loss per share in the prior year period. Gross margin as a percentage of revenue for this year’s second quarter rose to 25.9 percent, up from 24.8 percent for the prior year period, reflecting improved product mix and cost reduction activity. The 2004 second quarter results included approximately $69,000 of development expense for the Company’s BSST subsidiary that was not fully reimbursed by BSST customers.

“Achieving our third consecutive quarter of profitability is evidence of the significant progress we have made throughout the organization and the continuing appeal of CCS,” said Coker. “Automotive manufacturers and consumers are increasingly selecting CCS for their vehicles, and we continue to expand our presence in the worldwide automotive market. We are working closely with virtually every major automotive manufacturer and seat supplier to incorporate CCS in future vehicle lines. We have just initiated shipments of CCS for the new 2005 Nissan Gloria luxury sports sedan sold in Japan.”

The Gloria, which will offer CCS as an option, shares the same features as the Infiniti M45, which is sold in the U.S., and is the fourth vehicle manufactured by the Nissan Motor Company to offer CCS.

As has been widely reported, many automotive manufacturers experienced softness in vehicle sales during the second quarter, including sales of large vehicles such as SUVs (Sport Utility

Vehicles), due in part to increasingly high fuel prices in the U.S. and higher interest rates. “This had an impact on the sales of several vehicles offering CCS, and we expect this softness in the automotive market to continue for the balance of this year, particularly in the third quarter,” Coker added. “As a result, we expect to see growth in unit volume and revenue in the range of 15 to 20 percent for 2004. At these levels, we believe we remain well positioned to achieve our goal of being profitable for the full year.”

For the first six months of 2004, revenues increased 62 percent to $17.6 million, up from $10.9 million for the year-earlier period. Net income in this year’s first six months improved to $596,000, or $0.05 per basic share and $0.03 per fully diluted share, compared with a net loss of $1.5 million, or a $0.14 loss per share in the prior year period. Gross margin as a percentage of revenue for the first six months of 2004 rose to 24.6 percent, up from 22.7 percent for the prior year period. Results for this year’s first six months included approximately $136,000 of development expense for the Company’s BSST subsidiary that was not fully reimbursed by BSST customers compared to $258,000 for the year-earlier period.

Selling, general and administrative (SG&A) expenses in this year’s second quarter and six months increased 7 percent and 9 percent, respectively, to $1.4 million and $2.7 million compared with the prior year periods as the Company added headcount to support domestic and international customer service and marketing efforts.

Research and development expenses for the second quarter and six months of 2004 decreased 18 percent and 27 percent, respectively, to $561,000 and $1.2 million from comparable periods in the prior year. This decrease was due primarily to lower prototype costs associated with the Company’s next generation CCS system, MTM^™, which was launched in the latter part of 2003 and to customer funding received by Amerigon’s subsidiary, BSST. This customer support sustains BSST’s development of advanced thermoelectric technology and reduces significantly the Amerigon financial support required.

The June 30, 2004 balance sheet showed cash and cash equivalents of $4.0 million, total assets of $12.9 million, shareholder equity of $6.4 million and no bank debt. Subsequent to the close of the second quarter, Amerigon received an additional $3.4 million as a result of the exercise of warrants.

There are currently 15 vehicle lines from five major automotive manufacturers offering CCS. The vehicle lines currently offering CCS are Lincoln Navigator SUV, Lexus LS 430 luxury sedan, Toyota Celsior luxury sedan, Infiniti M45 luxury sports sedan, Ford Expedition SUV Eddie Bauer edition, Lincoln Aviator SUV, Infiniti Q45 luxury sedan, Lincoln LS luxury sedan, Cadillac XLR roadster, Cadillac Escalade ESV SUV, Mercury Monterey minivan, Cadillac Sedan Deville, Hyundai Equus luxury sedan, Nissan Cima luxury sedan and Nissan Gloria mid-sized sedan.
