MAXWELL TECHNOLOGIES REPORTS THIRD QUARTER FINANCIAL RESULTS

Ultracapacitor Revenue Increases 28% Sequentially; Offshore Manufacturing Boosts Gross Margin

CONFERENCE CALL & WEBCAST AT 5 P.M. (EDT) TODAY, OCTOBER 30, 2007 – DETAILS BELOW

SAN DIEGO, Calif. — Maxwell Technologies, Inc. (Nasdaq: MXWL) today reported a net loss of $2.6 million or $0.13 per share, on revenue of $14.2 million for its third quarter ended September 30, 2007. That compares with a net loss of $5.4 million, or $0.31 per share, on revenue of $14.0 million for the same period in 2006. The year-to-year net loss comparison is affected by a positive swing of $2.1 million, or $0.11 per share, in calculated fair value of warrants and conversion features of convertible debentures.

BOOSTCAP^® ultracapacitor revenue increased 28 percent sequentially, from $3.9 million in Q207 to $5.0 million in Q307, and the ongoing transition to lower cost offshore ultracapacitor assembly contributed to an increase in overall gross margin from 20 percent in Q207 to 24 percent in Q307. David Schramm, Maxwell’s president and chief executive officer, said that sales growth and overall gross margin improvement are expected to continue in the fourth quarter.

“The primary near-term revenue drivers for our BOOSTCAP products continue to be wind turbine pitch systems, industrial applications, including automated utility meters and power quality and backup power for telecommunications, and heavy transportation, including hybrid and electric buses and trucks and electric rail vehicles,” Schramm said. “Longer term, we continue to believe that automotive applications – both in managing increasing demands on the electrical system and in various hybrid vehicle configurations — represent the largest market opportunity for ultracapacitors, and we continue to devote significant energy and resources to collaborative development programs with automakers and Tier 1 automotive suppliers.”

Schramm noted that the company’s high voltage capacitor and microelectronics product revenue continued to be in line with expectations, combining for sales of $9.2 million in Q307. Other significant recent developments include:

• Announcement of a contract with Mercedes Car Group to design and produce ultracapacitors for an advanced engineering hybrid-electric drive train program incorporating a braking energy recuperation system that enables it to increase fuel efficiency and reduce emissions.

• Announcement of a $3 million contract with Astrium Satellites for space-qualified single board computers for the European Space Agency’s “Gaia” astronomy mission.

• Selection of Maxwell’s BOOSTCAP ultracapacitors for short-duration bridge power in Dantherm Power’s fuel cell-based uninterruptible power supply (UPS) system for telecommunications and fiber broadband facilities.

“These new supply agreements reflect the progress our direct sales force and our growing network of distribution partners are making in educating the design community, developing new markets and broadening and diversifying our customer base,” Schramm said. “We are also very pleased with the progress of the transition to offshore assembly for large cell BOOSTCAP products. In addition to providing immediate cost benefits, our contract manufacturing relationship in China gives us the capability to rapidly expand production to meet increasing demand.”

Cash, restricted cash and investments in marketable securities totaled $17.7 million as of September 30, 2007, compared with $21.3 million as of June 30, 2007, and the company subsequently raised approximately $15.3 million, after fees and expenses, through the sale of approximately 1.5 million shares of common stock, which closed on October 15. Complete financial statements will be available within the next few days with the filing of the company’s Quarterly Report on Form 10-Q with the Securities & Exchange Commission.
