Attention Business/Financial Editors:

Algonquin Power & Utilities Corp. Announces 2010 First Quarter Financial Results

OAKVILLE, ON, May 6 /CNW/ - Algonquin Power & Utilities Corp. (TSX: AQN), today announced financial results for the first quarter ended March 31, 2010. On October 27, 2009, Algonquin Power Income Fund became a wholly owned subsidiary of Algonquin Power & Utilities Corp. (collectively “APUC”), maintaining the same operations and business activities, but under a new corporate structure. Year-over-year results will be as compared to the results of Algonquin Power Income Fund in the relevant period.

For the first quarter of 2010, revenue was $45.9 million as compared to $52.2 million in the first quarter of 2009 and $43.4 in the fourth quarter of 2009. The decrease in revenue is primarily the result of the outage at the Energy-from-Waste facility and the lower than average wind resources in many areas of North America which impacted APCo’s Renewable Energy division.

Adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) was $17.9 million in the first quarter of 2010 as compared to $21.1 million in the first quarter of 2009 and $18.0 in the fourth quarter of 2009. The decrease in Adjusted EBITDA is primarily related to lower earnings from operations.

APUC reported net earnings in the first quarter of 2010 of $3.5 million or $0.04 per share as compared to net earnings of $4.2 million or $0.05 per share for the first quarter of 2009 and a net loss of $1.4 million or $0.03 per share in the fourth quarter of 2009.

Adjusted net earnings in the first quarter of 2010 were $3.0 million or $0.03 per share as compared to adjusted net earnings of $7.9 million or $0.10 per share in the first quarter of 2009 and $11.5 million or $0.14 per share in the fourth quarter of 2009. APUC uses adjusted net earnings to assess the net earnings of APUC without the effects of gains or losses on foreign exchange, foreign exchange forward contracts, and interest rate swaps as these are primarily non-cash items that are not reflective of the performance of the underlying business of APUC.

Performance Summary for the first quarter of 2010:

<<

• Revenue of $45.9 million in Q1 2010 as compared to $52.2 million in Q1 2009.

“While April results show a return to more normal wind conditions at our St. Leon facility, the earnings impact of the refurbishment of our Energy-from-Waste facility will continue to be felt during Q2. Nevertheless, we are confident that our committed 2010 growth initiatives including the previously announced electric utility acquisition, construction of Red Lily Phase I and Liberty Water rate case applications remain on track to deliver full year 2011 earnings per share in line with our targeted dividend payout ratio of 75% to 100%”, commented Ian Robertson, Chief Executive Officer of APUC.
