Alliant Energy Rides on Renewable Expansion & Strategic Investments

Alliant Energy (LNT) plans significant capital expenditures of $11.5 billion from 2025-2028, with over 40% earmarked for wind, solar, and energy storage projects, driving an anticipated 11% rate-base CAGR and targeting 5-7% long-term earnings growth. This strategic shift towards strengthening infrastructure and expanding clean assets has seen LNT shares climb 5.1% in the past three months, outperforming the industry's decline. However, the company faces potential headwinds from its reliance on third-party transmission assets and increasing competition from distributed generation.

Analysis

Alliant Energy (LNT) is executing a significant capital investment strategy focused on infrastructure modernization and renewable energy, which underpins its growth outlook. The company has outlined an $11.5 billion capital expenditure plan for 2025-2028, projected to drive a robust 11% compound annual growth rate in its rate base. A key facet of this plan is the allocation of over 40% of investments toward wind, solar, and energy storage, aligning LNT with the secular energy transition trend and building upon its existing base where regulated renewables accounted for nearly 32% of the rate base at year-end 2024. This strategy is supported by a targeted long-term annual earnings growth of 5-7% and a constructive regulatory environment. The market has responded favorably, with LNT shares gaining 5.1% over the past three months, directly contrasting with the industry's 1.3% decline. However, despite a positive outlook and a Zacks Rank of #3 (Hold), the company faces two material risks: an operational dependency on third-party transmission systems it does not control, and increasing competition from customer-owned generation, which could erode demand in its service territories.

Key Decisions for Investors

• Investors should view Alliant Energy's $11.5 billion capital expenditure plan as the primary driver for its targeted 5-7% earnings growth and 11% rate-base CAGR, making it a potentially attractive investment for those seeking exposure to the renewable energy transition within a regulated utility framework.
• It is critical to monitor for any degradation in the performance of third-party transmission assets LNT utilizes, as this represents a key operational vulnerability that could impede its ability to deliver power and realize growth targets.
• Given the stock's recent 5.1% outperformance against a declining industry, prospective investors should evaluate LNT's current valuation to determine if the positive growth outlook is already priced in.
• Consider the risk of demand erosion from increased adoption of self-generation technologies like solar panels by industrial and residential customers in LNT's key Iowa and Wisconsin markets.
