STAMFORD, Conn., Nov. 11, 2008 (GLOBE NEWSWIRE) -- Clean Diesel Technologies, Inc. (Nasdaq:CDTI) (XETRA:CDIA) (AIM:CDT), the cleantech emissions reduction company, today announced financial results for the third quarter and nine months ended September 30, 2008.

Recent Developments:

 * Revenue for the third quarter was $1.6 million compared to $2.5
   million in the third quarter of 2007,  with the decline mainly
   attributable to large upfront licensing fees in the third quarter
   of 2007
 * Revenue totaled $6.8 million for the nine months ended September
   30, 2008 compared to $3.9 million for the nine months ended
   September 30, 2007
 * Clean Diesel, EnBW Regional AG and H. Daugbjerg SA unveiled a
   diesel retrofit emissions control system at the IAA Commercial
   Vehicles 2008 trade show in Hannover, Germany in September
 * Michael Asmussen hired as Vice President of Sales, Americas, to
   lead domestic sales efforts

Dr. Bernhard Steiner, President and CEO of Clean Diesel Technologies, commented, "Clean Diesel has not been immune to the external macro events resulting in a global economic slowdown and the subsequent downturn in the automotive industry. Revenue for the quarter was $1.6 million compared with $2.5 million in the third quarter of last year, although it should be noted that last year's third quarter included significant upfront licensing fees which comprised much of our revenue for that period. Revenue also declined, as we expected, upon completion of the second of four compliance deadlines of the London Low Emission Zone (LEZ) in July 2008."

"Now with more than 300 patents and patents pending, the value of and demand for our portfolio of emission reduction technologies remains strong," continued Dr. Steiner. "Even though global events are driving an economic downturn, powerful forces are driving the demand for energy efficient solutions, and we see no signs of regulatory clean air mandates abating in the U.S. or abroad. This situation actually increases the competitive position and overall value of our unique technology portfolio. We believe the need for energy efficient emissions solutions is resulting in a new industry standard, embraced by engine manufacturers, for the combined use of Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR). Clean Diesel holds exclusive patents on the combined use of these technologies."

Dr. Steiner concluded, "Highlights in the third quarter include signing an important new license agreement with one of the leading companies in the industry. The brand awareness, know-how and value generated from participating in the London LEZ continues to create new opportunities, including participation with EnBW Regional AG, one of the largest German power network operators, and H. Daugbjerg SA, a Danish filter specialist, for a diesel retrofit emissions control system for the German market based on Clean Diesel's Purifier(tm) e4 technology. Our European LEZ experience is directly applicable in the Americas as we progress with verification by the California Air Resources Board for the Purifier e4 and participate in the California Off-Road Showcase and Supplemental Environmental Programs in Los Angeles and Oakland. These activities and developments underscore our global focus and market leadership."

Third Quarter 2008 Financial Results

Total revenue for the third quarter of 2008 was $1.6 million compared to $2.5 million in the third quarter of 2007. The decrease in the third quarter was primarily due to significant up-front license fees recognized in the prior year third quarter. Net loss for the third quarter of 2008 was $2.4 million or $0.29 per share compared to the Company's only profitable quarter to date with a net profit of $651,000 or $0.09 per share in the comparable period in 2007. Net loss for the quarter included $262,000 of non-cash stock-based compensation charges, compared to $91,000 in non-cash stock-based compensation charges in the three months ended September 30, 2007.

Total revenue for the nine months ended September 30, 2008 was $6.8 million, an increase of 74%, compared to $3.9 million for the same period in 2007. Net loss for the nine months ended September 30, 2008 was $6.1 million or $0.75 per share compared to $1.7 million or $0.25 per share in the comparable period in 2007. Net loss for the nine months ended September 30, 2008 included $1.0 million of non-cash stock-based compensation charges compared to $733,000 of non-cash stock-based compensation charges in the nine months ended September 30, 2007. The company also recorded an unrealized loss of $750,000 for the nine months ended September 30, 2008 that reduced the value of its investments in auction rate securities (ARS) with a corresponding reduction in stockholders' equity.

The Company disclosed that in October 2008, it received an offer from UBS AG for a put right permitting the Company to sell to UBS at par value the $11.7 million investment in ARS, previously purchased from UBS, at a future date (any time during a two-year period beginning June 30, 2010). The Offer also includes a commitment to loan the Company 75% of the UBS-determined value of the ARS at any time until the put is exercised. The Company accepted the UBS Offer on November 6, 2008.
