Ameren Corporation reported net income attributable to common shareholders of $115 million, or 46 cents per diluted share, for the three months ended December 31, 2020, compared to $94 million, or 38 cents per diluted share, for the same period in 2019. The increase was driven by infrastructure investments, new electric service rates, and lower operations and maintenance expenses.
Q4 2020 earnings increased due to increased infrastructure investments across all business segments.
New Ameren Missouri electric service rates effective April 1, 2020, positively impacted earnings.
Lower operations and maintenance expenses, primarily at Ameren Missouri, contributed to the earnings increase.
Increased interest expense and a lower allowed return on equity at Ameren Illinois Electric Distribution partially offset the favorable factors.
Ameren expects 2021 diluted earnings per share to be in a range of $3.65 to $3.85 and diluted earnings per share to grow at a 6% to 8% compound annual rate from 2021 through 2025.
