(a)Alliant Energy reports its share of equity earnings from certain corporate venture fund investments on a one-quarter lag. Equity earnings for the three and six months ended June 30, 2026 were primarily driven by increased valuations of certain underlying investments within the venture funds, including an investment in a company that provides onsite power solutions. In June 2026, the onsite power solutions company completed an initial public offering. Due to the one-quarter reporting lag, the financial effects of the initial public offering are expected to be recognized in Alliant Energy’s equity earnings in the third quarter of 2026.
