LNT · Q2 2025 Earnings

Bullish

Alliant Energy

Reported August 8, 2025

30-second summary

Alliant delivered Q2 non-GAAP EPS of $0.68 on revenue of $961M (+7.5% YoY), reaffirmed 2025 EPS guidance of $3.15–$3.25 and the 5–7% long-term EPS growth target, and — more importantly — moved its data center narrative from pipeline-on-a-slide to physical construction underway on three large-scale sites in Iowa and Wisconsin. Management telegraphed a Q3 capital expenditure plan update that will fold in signed energy services agreements, including the QTS Madison opportunity (sized at 750+ MW). The signal that matters: this is a utility ramping into a multi-year capex super-cycle, not a steady-state dividend stock.

Management tone

This is first coverage, so the multi-quarter narrative arc will start building next quarter. What's striking on a standalone basis is how far Alliant's posture sits from the typical utility's measured, rate-base-grinding cadence. Management talked like a company in the middle of a build cycle, not one waiting for regulators.

The dominant shift is from data center pipeline as a slide-ware opportunity to signed ESAs and steel in the ground. Management was explicit: "We're not just planning for growth, we're enabling it in real time. Physical construction has now started in both Iowa and Wisconsin on three large-scale data centers." The Cedar Rapids project ($10B, ~1 GW) is already in the plan; QTS Madison (750+ MW, ~1.5 GW potential) is the next major leg, and management committed to Q3 disclosure of signed ESAs and a refreshed capex plan. That sequencing — verbal confidence now, contractual disclosure in 90 days — is the part to underwrite.

The second shift is a deliberate transparency move on pipeline reporting. Management drew a contrast with industry practice: "our focus has been on reporting well-developed high confidence projects in contrast to reporting all early stage projects." In Q&A, Alliant put a number on it — "mature opportunities" require roughly an 85% probability of closure. That framework, if applied consistently, should reduce the credibility discount investors typically apply to utility growth pipelines.

Third, on tax credits, management projected unusual operational confidence. They've safe-harbored 100% of energy storage in the plan and 750 MW of 1,200 MW of wind, with line of sight on the remaining 450 MW. The hedge: if Treasury guidance shifts, the resource plan is built to pivot to gas, where Alliant has already secured turbine slot positions. That's not a hope — it's an inventoried option.

The hedging language that did appear ("confident in our ability to safe harbor", "expect Treasury guidance to reflect a pragmatic and constructive approach") sits in the typical utility register, but is narrowly scoped to externalities management cannot control. On internal execution, the tone is direct.

Recurring themes management leaned on this quarter:

Data center-driven economic development as transformational growth driverShift from planning to physical execution and constructionRegulatory alignment enabling renewable and storage project deploymentTax credit preservation through safe harbor strategyWin-win-win stakeholder value creation (customers, communities, investors)Strong balance sheet supporting capital deployment

Risks management surfaced:

Treasury guidance on start of construction rules for renewable tax credits could changeRegulatory approval timelines for pending dockets (QTS rate service agreement, additional energy storage, wind energy resources)Customer demand conversion from advanced discussions to signed agreementsPotential changes to long-standing tax credit guidance requiring flexible resource planning

Q&A highlights

Julian Dumoulin-Smith · Jefferies

Elaboration on QTS timeline and formalization, whether the customer was previously in 'mature opportunities' bucket, and what else is in the top of the funnel maturing.

QTS Madison is in advanced discussions with high confidence to close. Cedar Rapids load ramp: 200 MW in 2026, 300 MW starting 2027, ramping to 1,600 MW by 2028-2029. Q3 will provide updated guidance on signed ESAs and CapEx. Flexible resource plan allows adaptation to Treasury guidance without litigated resource planning delays.

QTS Madison CapEx roughly more than half the size of Cedar Rapids in the blue bucketCedar Rapids 2026: 200 MW; 2027: 300 MW to 1,000 MW; 2028-2029: up to 1,600 MW totalQ3 earnings call will update on signed ESAs and CapEx450 MW has line of sight for safe harbor qualification

Andrew Wiesel · Scotiabank

Clarification on $10 billion QTS investment already included in plan, estimated size of project in gigawatts, and whether new generation (CCGTs) would be needed. Also asked about technology pivot if safe harbor renewable tax credits unavailable.

$10B Cedar Rapids project already in green of plan (1 GW estimate). QTS Madison in dark blue as mature opportunity (~1.5 GW potential new load in advanced negotiations). New data center growth will primarily require new generation. Resource plan allows technology pivot based on Treasury guidance and affordability analysis. Secured turbine slot positions for gas investments.

Paul Freeman · Leidenberg

Confirmation on QTS opportunity size (750 MW or greater), likelihood of gas turbine supply for incremental load, and optimal settlement timing on PSCW case.

QTS opportunity fair to estimate at 750 MW or greater. Supply will be blend of resources detailed in Q3. PSCW staff testimony due August 12; settlement discussions likely to begin after that, with optimal window before September 9 hearing date. Collaborative work ongoing with PSCW staff and interveners.

Anthony Prattle · Mizuho

What determines movement within the 40-45% equity ratio range, and how should investors evaluate mature opportunities compared to peers given sector-wide pipeline robustness.

Equity ratio range flexibility driven by FFO-to-debt metrics; lower end achievable with stronger metrics, higher end if metrics weaken. Mature opportunities defined by ~85% probability threshold of deal closure with active discussions and high confidence. Distinguishes from industry practice to avoid double-counting and inflated pipelines.

What to watch into next quarter

Q3 capital expenditure plan update: management has explicitly teed up a refreshed multi-year CapEx plan incorporating signed ESAs. Watch for the magnitude of the lift and whether QTS Madison converts to a signed agreement on or before the call.

PSCW case resolution: staff testimony due August 12, hearing September 9 — watch for settlement before hearing, which would compress regulatory risk on the Wisconsin storage and wind dockets.

Treasury safe harbor guidance: outcome on start-of-construction rules will determine whether the remaining 450 MW of wind qualifies for tax credits or gets pivoted to gas. Either is workable; clarity matters more than direction.

2026 EPS guide framework: with 2025 reaffirmed at $3.15–$3.25 and long-term growth target at 5–7%, watch whether the Q3 update implies the high end of the long-term range given the load ramp accelerating in 2026.

Equity issuance signaling: with a 40–45% equity ratio range, 40–50% equity funding of incremental capex disclosed on the call, and CapEx accelerating, watch for the dollar magnitude of incremental equity implied by the Q3 capex refresh — material to TSR math.
