Timing: Alliant is scheduled to release 2Q26 results after the market closes on Thursday, July 30, 2026. The associated earnings call is Friday, July 31 at 9:00 a.m. CT—not July 30.
Alliant enters 2Q earnings with its core 2026 earnings plan intact and a meaningful long-term growth narrative centered on data-center load in Iowa and Wisconsin. The near-term question is whether ordinary utility execution—weather-normalized sales, O&M, financing costs, and capital-project timing—continues to support the company’s $3.36–$3.46 ongoing EPS guidance. The larger valuation question is whether management can further de-risk the potential upside from contracted and prospective large-load customers without increasing concerns around capital intensity, dilution, MISO capacity accreditation, or customer-concentration risk.
LNT closed July 29 at $72.03, up roughly 9.8% year to date but down about 5.6% from its June 30 close of $76.29. That leaves the report positioned as a potential catalyst for a reset in sentiment—especially if management offers more confidence on load conversion, resource-plan timing, and financing.
In 1Q26, Alliant reported $0.82 of ongoing EPS, versus $0.83 a year earlier, while reaffirming its full-year $3.36–$3.46 range. The first quarter represented approximately 25% of the guidance midpoint despite mild weather, which management characterized as an encouraging start.
The 2Q comparison is relatively clean: Alliant generated $0.68 of GAAP and ongoing EPS in 2Q25. Last year’s result benefited from higher revenue requirements from capital investment and a modest favorable weather contribution, partly offset by higher depreciation and financing costs.
For 2Q26, investors should focus less on a mechanical year-over-year EPS comparison and more on whether management confirms that its full-year assumptions remain valid:
A guide reaffirmation would likely be viewed as the base-case outcome. A raise may be less likely this early, given management’s stated intent to provide a more complete resource-plan and long-term-growth update with 3Q results.
In 1Q, higher rate-base-related revenue requirements contributed $0.05 per share at IPL and $0.10 per share at WPL, aided by higher allowance for funds used during construction (AFUDC). Those gains were offset by higher depreciation, financing expense, and O&M—particularly maintenance and costs associated with new energy resources.
That same push-pull should define 2Q:
| Positive factors | Offset / risk factors |
|---|---|
| Rate-base growth and approved investment recovery | Depreciation from the growing asset base |
| AFUDC from a larger construction program | Interest expense and refinancing costs |
| Potential favorable summer weather | O&M, including generation and distribution maintenance |
| Customer growth and commercial/industrial demand | Timing of capital in-service dates |
| Tax-credit monetization and utility regulatory mechanisms | Equity issuance / share-count growth |
The key takeaway is that Alliant’s earnings model is working as intended: invest capital, grow regulated rate base, and recover returns through constructive regulatory frameworks. However, the model is increasingly capital-intensive, making execution and financing discipline essential.
Alliant’s large-load opportunity is substantial. At the end of 1Q, management cited:
This contracted demand is more than 60% of Alliant’s current peak demand, according to management. It is the primary source of potential upside to Alliant’s previously stated expectation of 7%+ EPS CAGR for 2027–2029.
Investors should seek evidence that the opportunity is transitioning from a compelling narrative into an investable capital-and-earnings plan:
Additional executed service agreements.
Even a modest new agreement would reinforce that the 2–4 GW pipeline is converting. Conversely, no new agreements would not necessarily be negative, but management needs to affirm the pipeline’s maturity and timing.
Load-ramp visibility.
The most important disclosure is not merely gigawatts signed, but when customers will consume power and when associated generation and transmission investments earn returns.
Individual customer rates and cost responsibility.
Alliant’s investment case depends on large-load customers bearing the costs they cause, while providing a margin that benefits legacy customers. Updates on individual customer-rate filings—particularly for Iowa data centers and the Meta project in Wisconsin—would be material.
The updated Iowa resource plan.
Management has indicated that its 3Q update should refresh the Iowa resource plan for incremental load and updated MISO accreditation assumptions. Investors should look for any preliminary indication in 2Q of the size, timing, and mix of generation needed.
Management has emphasized a capacity-oriented solution built around batteries and simple-cycle natural-gas turbines, rather than immediately committing to large combined-cycle plants. This reflects Alliant’s wind-rich Iowa footprint: batteries and peakers can support reliability and capacity needs while preserving the option to add combined-cycle capability later if energy demand warrants it.
Current notable items include:
This is strategically attractive because it can align incremental investment with customer demand. But the investment case becomes more sensitive to the following risks:
Alliant’s current regulatory setup is a relative strength. There are no active base-rate reviews planned in 2026, and Iowa’s framework allows base electric rates to remain stable through at least the end of the decade while Alliant earns authorized returns through retained tax credits and incremental energy margins.
Still, the upcoming report should provide updates on several open items:
Constructive outcomes could validate Alliant’s claim that new customers will fund the incremental infrastructure they require. Delays or concessions could pressure the long-term growth case.
Alliant has laid out a sizable financing program to support its capital plan. Management expects approximately $2.4 billion of common-equity needs over four years, of which roughly $1.3 billion had already been raised through forward equity agreements as of 1Q, covering planned needs through 2027. The company also established a new $1 billion at-the-market program to support remaining expected equity needs through 2029.
Other relevant points:
The financing plan is proactive and broadly consistent with a high-growth regulated utility. Still, investors will watch for any increase in the capital plan that requires more equity than currently contemplated, especially before the data-center load is fully online.
The base-case 2Q outcome is another guidance reaffirmation, supported by capital-investment-driven utility earnings but moderated by higher financing, depreciation, and operating costs. The more consequential issue is whether management can offer incremental evidence that its 3.4 GW of contracted data-center demand and 2–4 GW opportunity set will convert into regulated investment, on a schedule and under customer-rate structures that are clearly accretive to existing shareholders.
For investors, the highest-value disclosures will concern new service agreements, customer load ramps, regulatory milestones, early resource-plan details, and whether financing requirements remain within the existing framework. The quarterly EPS print matters—but the durability and economics of Alliant’s large-load strategy will likely drive the stock’s reaction.
