Algonquin Power & Utilities Corp. Announces Plans to Issue 2014 Fourth Quarter and Year End Financial Results

OAKVILLE, ON, March 15, 2015 /CNW/ - Algonquin Power & Utilities Corp. (TSX: AQN) (“APUC”) today announced that financial results for the fourth quarter and year ended December 31, 2014 will be issued at 6 a.m. eastern time on Monday March 16, 2015.

Shortly before the previously scheduled release of its 2014 financial results, APUC became aware of certain anonymous, unproven allegations regarding certain APUC personnel. APUC shared the allegations with its auditors, and delayed releasing its financial results in order to consider, together with the auditors, whether certain of the allegations which related to APUC’s financial reporting and related practices could impact its financial results. This assessment, which was led by a committee of independent directors with the assistance of independent legal and accounting advisors, is now complete and APUC will be releasing its financial results, having determined that the allegations did not impact the financial results. The committee’s investigation into the allegations which are not related to APUC’s financial reporting and related practices is continuing to be dealt with in a confidential manner in accordance with APUC’s complaint-handling policies.

Following the issuance of the fourth quarter 2014 financial results, APUC will hold a conference call at 10:00 a.m. eastern time on Monday, March 16, 2015, hosted by Chief Executive Officer, Ian Robertson and Chief Financial Officer, David Bronicheski.
