VENTURA, CA--May 12, 2011: Clean Diesel Technologies, Inc. ("Clean Diesel" or the "Company"), a cleantech emissions reduction company, announced today its financial results for the first quarter ended March 31, 2011.

• Total first quarter revenue was $13.8 million, up 11.3% compared to prior year.
• First quarter revenue for Clean Diesel's Heavy Duty Diesel Systems division increased $1.9 million, or 25.3% compared to prior year.

First Quarter 2011 vs. First Quarter 2010

The October 15, 2010 business combination with Catalytic Solutions, Inc. (or "CSI"), which we refer to as the "Merger" was accounted for as a reverse acquisition. Accordingly, Clean Diesel's (the legal acquirer's) consolidated financial statements are now those of CSI (the accounting acquirer), with its assets and liabilities and revenues and expenses being included in CSI's financial statements effective from October 15, 2010, the closing date of the Merger. As such, the amounts discussed below for periods prior to the Merger are those of CSI and its consolidated subsidiaries, with amounts of legacy Clean Diesel operations included from the date of the Merger.

Total revenue for the first quarter of 2011 was $13.8 million up 11.3% from $12.4 million for the same quarter in 2010. Total revenue includes $0.7 million from legacy Clean Diesel business as a result of the Merger. Net loss for the first quarter of 2011 was $2.3 million, or $0.58 per share, compared to net income of $2.6 million, or $4.70 per share, in the comparable period in 2010. Net income for the first quarter of 2010 included a pre-tax gain of $3.9 million from the sale of intellectual property rights to our Asian joint-venture partner. Diluted common shares outstanding were 3,984,000 in the current quarter compared to 552,000 in the same quarter a year ago, with the increase in the number of shares due principally to the effect of the Merger and related transactions and the subsequent exercise of certain warrants issued in connection with the Merger.

Revenue for Clean Diesel's Heavy Duty Diesel Systems division for the quarter ended March 31, 2011 increased $1.9 million, or 25.3%, to $9.4 million from $7.5 million for the quarter ended March 31, 2010.  This includes $0.7 million from legacy Clean Diesel business as a result of the Merger, all of which is included in Clean Diesel's Heavy Duty Diesel Systems division.

Revenue for Clean Diesel's Catalyst division for the quarter ended March 31, 2011 decreased $0.4 million, or 7.8%, to $4.7 million from $5.1 million for the quarter ended March 31, 2010.

At March 31, 2011 and December 31, 2010, respectively, Clean Diesel had cash and cash equivalents of $1.2 million and $5.0 million. Not included in such amounts are the net proceeds from the May 2011 sale of $3.0 million principal amount of Clean Diesel's 8.0% subordinated convertible notes, which are to be used for general working capital purposes. Working capital surplus was $1.7 million at March 31, 2011 compared to a working capital surplus of $2.8 million at December 31, 2010. Additional information about the Company's financial results will be available in its Quarterly Report on Form 10-Q to be filed with the U.S. Securities and Exchange Commission: http://www.sec.gov. A copy of the Form 10-Q will be posted on the Company's website at www.cdti.com.

Charles F. Call, Chief Executive Officer of Clean Diesel, stated, "Overall, I am encouraged by our results this quarter as our markets and the global economy continue to strengthen. Our business divisions, Heavy Duty Diesel Systems and Catalyst, performed largely as planned. We continue to be optimistic about growth in our Heavy Duty Diesel Systems division and we were pleased to report revenue growth of more than 25% for this division in the first quarter compared to the same period in 2010. Going forward, depending on the timing of certain heavy duty diesel retrofit programs, we expect to see continued improvement in our business as we capture the opportunities available in the London Low Emission Zone (LEZ) in the second half of the year. In addition, on April 6, 2011 the California Air Resources Board (CARB) announced an incentive program for truck operators to accelerate purchases of particulate filter retrofits to the second quarter of 2011.  This incentive program is related to a mandatory program announced by CARB in late 2010 requiring heavier diesel vehicles to conform to new standards between 2012 and 2016, with 90% by 2014. Our team is very enthusiastic about this opportunity and we have already begun to see increased business activity in our Heavy Duty Diesel Systems division as a result of this program in the second quarter.  

"As anticipated, our Catalyst division sales decreased as a result of an automaker accelerating the manufacture of a vehicle that requires a catalyst product meeting a higher regulatory standard than the product we currently supply to the automaker, which was only partially offset by growth in sales to another automaker and sales to a new automaker customer in the first quarter. Looking further into 2011 and as previously discussed, the earthquake and subsequent tsunami in Japan resulted in one of our Catalyst division customers reducing their production. This unfortunate event will result in lower catalyst sales in the second quarter of 2011. We are in frequent communication with our customer and, at this time, it is not certain as to how long this disruption will last.

"We anticipate that following approval by the regulatory agencies (expected sometime in the second quarter of 2011) we will have the ability to supply our own manufactured catalyst products to our Heavy Duty Diesel Systems division, which we expect will improve our total gross margins."

Mr. Call concluded, "Through our continued investments in local capabilities in fast-growing global markets, development of new technology, and cost structure reductions, we have taken significant steps to position our company for the future. We continue to evaluate our options for providing the additional working capital that will be needed. We are optimistic about the growth opportunities presented by our markets and confident we can further drive value creation for our shareholders while steadily increasing the delivery of customer-focused innovation."
