DTE EnergyRevenue increased 23% in 2021, but operating profit fell 23%, mainly due to the rapid increase in business costs and an increase of 400 million in “other special expenses”. Without the impact of “other special expenses,” there was little change in net profit. The current price-earnings ratio of 27.7 times requires more growth data to support it.
