ALLETE, Inc. reports first quarter 2019 earnings of $1.37 per share

DULUTH, Minn. - ALLETE, Inc. (NYSE: ALE) today reported first quarter 2019 earnings of $1.37 per share on net income of $70.5 million and operating revenue of $357.2 million. Last year’s results were 99 cents per share on net income of $51.0 million and operating revenue of $358.2 million. Results in the first quarter of 2019 included a 19 cents per share gain from the sale of U.S. Water Services.

“We are pleased with our strong financial results for the quarter and the advancement of major strategic initiatives which will drive industry leading growth in coming years. During the first quarter we completed the sale of U.S. Water Services which provides us with over $260 million of added liquidity to fund our clean energy growth initiatives across the Company,” said ALLETE Chairman and CEO Al Hodnik. “We are excited about our positioning for further clean energy expansion across all of the ALLETE businesses which will continue to capture value for our shareholders.”

ALLETE’s Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power (SWL&P) and the Company’s investment in the American Transmission Co. (ATC), recorded net income of $51.5 million, compared to $43.9 million in the first quarter of 2018. Earnings reflect higher net income at Minnesota Power primarily due to lower operating and maintenance expenses, increased cost recovery rider revenue, lower property tax expense, and higher sales to residential customers resulting from cooler weather conditions than in the first quarter of 2018. These increases were partially offset by lower industrial sales and the timing of fuel adjustment clause recoveries. Net income at SWL&P increased over last year due to higher rates implemented the first of this year, and lower operating and maintenance expense. ALLETE’s earnings in ATC were higher than in 2018 primarily due to additional equity investments.

ALLETE’s Energy Infrastructure and Related Services businesses, which include ALLETE Clean Energy and U.S. Water Services, recorded first quarter 2019 net income of $5.8 million and a net loss of $1.1 million, respectively. Earnings at ALLETE Clean Energy decreased $2.3 million from 2018, primarily due to lower wind resources and availability at its wind energy facilities which negatively impacted revenue, slightly offset by higher production tax credits generated during the quarter. The net loss at U.S. Water Services was similar to 2018.

Corporate and Other, which includes BNI Energy and ALLETE Properties, recorded net income of $14.3 million for the quarter, compared to net income of $0.4 million in 2018. Net income in 2019 included the gain on the sale of U.S. Water Services of approximately $10 million after-tax. Net income in 2019 also included additional income tax benefits to record income taxes at the estimated annual effective tax rate.
