Alliant Energy Corporation (LNT) — Business Overview

Business Description

Alliant Energy is a Midwest regulated electric and natural gas utility serving approximately 1.01 million electric and 435,000 natural gas customers across Iowa and Wisconsin through its two primary subsidiaries: Interstate Power and Light Company (IPL, Iowa) and Wisconsin Power and Light Company (WPL, Wisconsin). The company is in active transformation — retiring coal, expanding wind/solar/storage, and capitalizing on a data center boom anchored by 3 GW of hyperscaler load agreements that could drive 50% peak demand growth by 2030.

Revenue Model

As a regulated utility, Alliant Energy earns authorized returns on its rate base set by the Iowa Utilities Board and Wisconsin Public Service Commission. Revenue comes from tariff-based electric and natural gas sales to residential, commercial, industrial, and large-load (data center) customers. Capital investments in generation, transmission, and distribution earn regulated returns once approved in rate cases or via annual recovery mechanisms. The $13.4B four-year capex plan drives compounding rate base and earnings growth.

Products & Services

• Electric distribution and transmission — Iowa (IPL) and Wisconsin (WPL) service territories
• Natural gas distribution — local delivery to ~435K gas customers across both states
• Renewable generation — 1,800 MW wind + 1,500 MW solar (completed 2024) + 1,000 MW storage (planned)
• New gas-fired generation — 1,600 MW of natural gas resources planned to serve data center load
• Data center power supply — 4 Electric Service Agreements (ESAs) totaling 3 GW with hyperscaler customers

Customer Base & Go-to-Market

Alliant serves ~1.45 million total customers across captive regulated service territories in Iowa and Wisconsin. The transformational new customer class is hyperscale data centers: 4 ESA agreements for 3 GW of load will drive 50% peak demand growth by 2030 and >60% Q1 2026 peak demand growth year-over-year. Wisconsin and Iowa's low electricity costs, land availability, and cold climate are key data center location attractors.

Competitive Position

Alliant is a regulated monopoly in its Iowa and Wisconsin service territories. It competes for capital allocation vs. utility peers but faces no direct utility competition. Iowa and Wisconsin's regulatory frameworks have been constructive — a December 2025 unanimous Wisconsin rate settlement (2026-2027) provides earnings visibility. Alliant is recognized as an S&P 500 Dividend Aristocrat with 21 consecutive years of dividend increases and 320 consecutive quarters of payments since 1946.

• Adj. EPS CAGR (2024–2026): 5–7% target | Rate Base CAGR driven by $13.4B capex plan

Growth Profile

Alliant has delivered steady 5–6% adj. EPS growth through disciplined capital investment and rate base expansion in Iowa and Wisconsin. Revenue declined in 2023–2024 due to lower natural gas prices flowing through to customers; underlying utility earnings continued to grow. The company raised its four-year capex plan by 17% to $13.4B to meet data center demand, adding 1,600 MW gas, 1,000 MW storage, and 1,300 MW renewables alongside the 3 GW hyperscaler ESA load commitments.

Forward Estimates

• FY2025 adj. EPS: ~$3.20–3.25 (Q2 2025 beat at $0.68 vs $0.62 consensus)
• FY2026: Strong Q1 momentum — >60% peak demand growth from data center load
• 4-year capex plan: $13.4B (Iowa + Wisconsin; raised 17% from prior plan)
• Hyperscaler ESAs: 3 GW total load by 2030
• Dividend: 21 consecutive annual increases; ~$1.52/share annual
• Analyst avg. price target: ~$73.83 (consensus Moderate Buy)

Alliant Energy Corporation (LNT) — Investment Catalysts & Risks

Bull Case Drivers

1. 3 GW Hyperscaler ESA Load = 50% Peak Demand Growth by 2030 — Alliant has executed four Electric Service Agreements with hyperscale data center customers totaling 3 GW of new load, with Q1 2026 already showing >60% peak demand growth year-over-year. Wisconsin and Iowa's cold climate, land availability, and low electricity costs make them prime data center destinations. This step-change in load is the primary driver of Alliant's 17% capex plan increase to $13.4B and underpins multi-year earnings growth that sets LNT apart from most Midwest regulated peers.

2. $13.4B Capex Plan + Constructive Regulatory Environment — Alliant's four-year capital plan adds 1,600 MW of new gas, 1,000 MW of energy storage, and 1,300 MW of renewables to serve surging demand. Iowa and Wisconsin have been constructive regulatory environments — a December 2025 unanimous Wisconsin rate settlement for 2026–2027 provides near-term earnings certainty and removes a key execution risk. Capital investments earn regulated returns through rate cases and annual recovery mechanisms, translating directly to rate base growth and EPS compounding.

3. Dividend Aristocrat + 21-Year Raise Streak — Alliant has raised its dividend for 21 consecutive years and paid dividends for 320 consecutive quarters since 1946, earning S&P 500 Dividend Aristocrat status. The ~3% yield, steady 5–7% EPS growth, and Wisconsin/Iowa regulatory stability make LNT a core holding for income-focused institutional investors. The stock hit an all-time high in March 2026, validating the data center thesis with market endorsement.

Bear Case Risks

1. Regulatory Lag and Rate Case Execution Risk — Alliant's earnings growth depends on timely recovery of its $13.4B capital program through rate cases and annual mechanisms in two states. While the Wisconsin 2026–2027 settlement removes near-term uncertainty, Iowa rate cases remain a risk. Any unfavorable rate decisions, disallowances, or extended lag before new rates take effect could compress returns on the massive capex program. Regulatory concentration in just two states amplifies the impact of adverse decisions.

2. Data Center Load Materialization Risk — Alliant's elevated capex plan and stock valuation are underwritten by 3 GW of hyperscaler ESAs. If data center construction timelines slip, hyperscalers defer buildout, or power demand from AI workloads disappoints broader market expectations, Alliant may have committed capital to generation capacity that earns below-plan returns. The utility would need additional rate cases to recover costs, creating regulatory and earnings uncertainty.

3. Interest Rate and Capital Markets Sensitivity — Alliant carries ~$7.5B in debt and requires sustained capital market access to fund a $13.4B four-year program. The dividend yield (~3%) relative to utility peers and P/E (~25x) leaves limited multiple expansion headroom. If interest rates remain elevated, financing costs for new debt rise, thinning returns on incremental capital — a self-reinforcing constraint. Rate-sensitive investors who bought for yield may rotate out if Treasury yields spike, compressing the stock.

Upcoming Events

• Q2 2026: Quarterly earnings — data center load ramp update and capex spend pace
• FY2026: Wisconsin rate settlement in effect (2026–2027 rates locked)
• Iowa rate cases: Key for cost recovery on new generation and data center investment
• 2027–2030: 3 GW hyperscaler ESA load delivery milestones

Analyst Sentiment

Analyst consensus is Moderate Buy: 4 Buy, 3 Hold, 0 Sell. Average 12-month price target ~$73.83 — slightly below recent all-time high range (stock hit ATH in March 2026). Analysts view LNT as a quality Midwest data center utility play with visible earnings growth, though some hold ratings reflect valuation premium vs. slower-growing peers.
