Algonquin Power & Utilities Corp.'s board of directors has approved and declared the following common and preferred share dividends:

• 10.85 U.S. cents per common share, payable on Oct. 13, 2023, to the shareholders of record on Sept. 28, 2023, for the period from July 1, 2023, to Sept. 30, 2023. Registered shareholders can elect to receive the dividend in Canadian dollars in the amount of 14.60 cents;
• 32.263 cents per preferred share, Series A, payable in cash on Oct. 2, 2023, to preferred share, Series A, holders of record on Sept. 15, 2023, for the period from June 30, 2023, to, but excluding, Sept. 30, 2023;
• 31.819 cents per preferred share, Series D, payable in cash on Oct. 2, 2023, to preferred share, Series D, holders of record on Sept. 15, 2023, for the period from June 30, 2023, to, but excluding, Sept. 30, 2023.

Each of the foregoing dividends will be paid in cash. Effective March 16, 2023, Algonquin Power suspended the dividend reinvestment plan (DRIP) for its common shares. If Algonquin elects to reinstate the DRIP in the future, shareholders who were enrolled in the DRIP at its suspension and remain enrolled at reinstatement will automatically resume participation in the DRIP.

The quarterly dividends payable on common shares are declared in U.S. dollars. Beneficial shareholders (those who hold common shares through a financial intermediary) who are resident in Canada or the United States may request to receive their dividends in either U.S. dollars or the Canadian-dollar equivalent by contacting the financial intermediary with whom the common shares are held. Unless the Canadian-dollar equivalent is requested, holders of common shares will receive dividends in U.S. dollars, which, as is often the case, the financial intermediary may convert to Canadian dollars. Registered holders of common shares receive dividend payments in the currency of residency. Registered holders of common shares may opt to change the payment currency by contacting TSX Trust Company at 1-800-387-0825 prior to the record date of the dividend.

The Canadian-dollar equivalent of the quarterly common share dividend is based on the Bank of Canada daily average exchange rate on the day before the declaration date.

Pursuant to the Income Tax Act (Canada) and corresponding provincial legislation, Algonquin hereby notifies holders of common shares, preferred shares, Series A, and preferred shares, Series D, that such dividends declared qualify as eligible dividends.
