Euro Tech Holdings Company Limited Reports Interim Results For The Six Months Ended June 30, 2011

Hong Kong — December 12, 2011 — Euro Tech Holdings Company Limited (Nasdaq: CLWT) today reported its unaudited financial results for the six months ended June 30, 2011.

The Company’s revenues for the six months ended June 30, 2011 were approximately US$9,554,000, a 7.8% decrease as compared to approximately US$10,363,000 for the six months ended June 30, 2010. The net income for the six months ended June 30, 2011 was approximately US$12,000, as compared to the net loss of approximately US$451,000 for the six months ended June 30, 2010.

Revenues from engineering business increased by approximately US$1,330,000, but were not enough to offset the further drop of revenues from trading business of US$2,139,000.

The Company’s operating result changed from the net loss for the six months ended June 30, 2010 to the net income for the six months ended June 30, 2011. This was principally due to the reduction of selling and administrative expenses of approximately US$428,000 which included the reduction of operating expenses of approximately US$100,000 as a result of streamlining operation and gain on the disposal of a property of approximately US$328,000.

The company is positive about the increase of wastewater treatment business outside China in coming months, as many International Engineering Companies prefer to source wastewater treatment equipment and engineering services in China for their projects in other countries.

The company is also positive about the progress of the development of its Ballast Water Treatment System (“BWTS”) for the worldwide maritime industry. The BWTS is now under vigorous testing to prepare for the land and sea certification tests in America in March 2012.

Ballast water treatment is an imminent requirement by The International Maritime Organization (“IMO”) to prevent the biological unbalance caused by the estimated 12 billion tons of ballast water transported across the seas by ocean-going ships when their ballast water tanks are emptied or refilled. The market potential for retrofits and new installations in these old and new ocean-going ships is enormous.

Since mid 2010, the company has been investing a lot of its resources and has recently taken part in two International conferences In Singapore and Turkey for the Ballast Water Treatment System. The company is upbeat about the potential Ballast Water Treatment business that will generate steady revenues and incomes based on orders from retrofits and new installations from ships in future.
