Future Outlook

The proposed acquisition of Calpine Corporation is expected to close by December 31, 2025, with a potential extension to June 1, 2026, and is anticipated to enhance the investment-grade credit profile, generate synergies, and provide accretion to earnings per share and free cash flow. The company expects to fund the cash portion of the transaction through cash on hand and cash flow generated by Calpine. The 20-year PPA with Meta for the Clinton Clean Energy Center supports its continued operation for two decades beyond the state's ZEC program, with plant uprates expected to be complete in 2029 and qualify for the 45Y PTC. Depreciation provisions for the Conowingo Hydroelectric Project assume operation through 2071, based on the expectation of a 50-year license. The One Big Beautiful Bill Act (OBBBA) reinforces the long-term economic viability of nuclear generation assets. The company expects cash flows to be sufficient to meet operating expenses, financing costs, and capital expenditure requirements. The long-term impact of tariffs on the energy sector remains uncertain, and the company is monitoring the Russia and Ukraine conflict for potential impacts on nuclear fuel supply and costs. The nuclear PTC remains subject to additional guidance from the U.S. Treasury and IRS, which may materially impact total benefits.
