Key risks (from latest filing)
["Regulatory risk: Rate increases and cost recovery mechanisms are subject to approval by state and federal regulators (MoPSC, ICC, FERC) with regulatory lag that could adversely affect profitability","Capital investment and cost control: Substantial required investments in renewable generation, battery storage, and grid modernization must be recovered within regulatory frameworks; failure to obtain timely approvals or cost overruns could impact returns","Demand and customer growth uncertainty: Revenue depends on realizing forecasted electricity demand including speculative demand from new data center customers and other large industrial loads, which may not materialize as expected"]
