At the same time existing customers have extended their usage. All of our businesses and technological areas are progressing according to plan, and we are pleased with their continued innovation and development. We have also entered into several trials in the fields of marine, rail and agricultural / off road applications. All of these trials are performing very positively and the Company is expecting to turn these trials into ongoing customers. "With this experience the Company is now poised to broadly go to its markets and offer both, large and small corporations, its leading emission reduction technologies coupled with meaningful improvements in fuel economy." Operational Review Clean Diesel's revenue more than doubled in the third quarter of 2006 compared with the same period in 2005 and, for the first nine months of 2006, revenues were up 42% compared with the same period in 2005. Increased Platinum Plus fuel borne catalyst sales are driving the revenue increases. In the third quarter of 2006, four Platinum Plus® fuel-borne catalyst (FBC) fleet trials were completed with annual Platinum Plus® FBC revenue of approximately US$250,000. Each of these trials has converted into a customer with two of these fleets based in the United States and two in Europe, in the areas of people transportation, delivery, food and waste management. Furthermore, several additional high profile customers have been attracted to the trial program for the first time.with larger fleets. These trials are underway with initial results confirming the strength of Clean Diesel's products and are expected to be successfully completed during the fourth quarter. Expenses in the third quarter of 2006 were down slightly in comparison to the same period of 2005 as a result of lower compensation expense relating to the first quarter severance charge, as well as the timing of R&D programs, mostly offset by increased European professional expenses and non-cash compensation expense (US$49,000) for stock options. For the months January to September 2006, operating expenses were up slightly versus the same period of 2005 due to higher R&D investment related to increased engineering and testing for the Clean Diesel wire-mesh diesel particulate filter technology, non-cash compensation expense (US$155,000) for stock options, and severance recognized in the first quarter of 2006. As now required under the United States Financial Accounting Standard 123R, the fair value of options granted must be calculated and the expense recognized over the vesting term of the option. - ENDS - For further information: Clean Diesel Technologies, Inc. http://www.cdti.com Bernhard Steiner, President and 300 Atlantic Street, Suite 702 CEO Stamford, CT 06901-3522 Media / investor enquiries: Abchurch Communications www.abchurch-group.com Heather Salmond / Franziska Boehnke 100 Cannon Street, Email: London heather.salmond@abchurch-group.com EC4N 6EU Tel: +44 (0) 20 7398 7700 About Clean Diesel Technologies, Inc.
