Alliant Energy Benefits From Investments & Renewable Expansion

Alliant Energy (LNT) is increasing its capital expenditure guidance by 26% to $11.5 billion for 2025-2028, with over 40% allocated to wind, solar, and energy storage, supporting an anticipated 11% rate-base CAGR; this investment aims to modernize the grid and expand clean energy assets. While LNT benefits from a growing customer base and favorable regulation, it faces challenges due to its reliance on third-party transmission systems and potential competition from self-generation by large industrial customers. In the past month, LNT stock has outperformed its industry, rising 1.8% compared to the industry's 1.3% growth.

Analysis

Alliant Energy (LNT) has announced a significant 26% increase in its long-term capital expenditure guidance to $11.5 billion for the period 2025-2028, a move anticipated to support an 11% compound annual growth rate (CAGR) in its rate base during the same timeframe. A substantial portion of this capex, exceeding 40%, is earmarked for investments in wind, solar, and energy storage, positioning LNT towards a cleaner generation portfolio. This strategic investment aligns with the company's efforts to modernize its grid and serve an expanding customer base, which, along with favorable regulatory conditions and ongoing economic development in its service territories, underpins its earnings prospects. Despite these positive developments and a recent stock performance that saw shares rise 1.8% in the past month, outperforming the industry's 1.3% growth, LNT carries a Zacks Rank #3 (Hold). Key challenges include its reliance on third-party transmission systems, which could impact operational stability if these external systems underperform, and increasing competition from self-generation and alternative energy sources. While LNT's growth initiatives are robust, peer companies such as CenterPoint Energy (CNP), Evergy (EVRG), and DTE Energy (DTE) currently hold a Zacks Rank #2 (Buy) and exhibit strong projected long-term earnings growth rates of 7.76%, 5.7%, and 7.64% respectively, with positive year-over-year EPS growth estimates for 2025.

Key Decisions for Investors

• Investors should monitor Alliant Energy's execution of its $11.5 billion capex plan and its ability to achieve the projected 11% rate-base CAGR, particularly the progress in renewable energy expansion.
• Carefully evaluate the risks associated with LNT's dependence on third-party transmission infrastructure and the potential impact of increasing competition from customer-owned generation before adjusting positions.
• Given LNT's 'Hold' rating, and the 'Buy' ratings for peers like CNP, EVRG, and DTE with strong growth outlooks, consider a comparative analysis within the utility sector to assess relative investment attractiveness.
