Alliant's 7%+ EPS Growth Plan Is Only as Strong as the Data Center Build-Out

Alliant's near-term results hold up, but the growth thesis still depends on execution

Alliant's latest update kept the core message intact: management is leaning into more grid investment and expects faster earnings growth, but the plan only works if data-center load arrives on time and is recovered through rates.

Just last week, Alliant reported Q2 GAAP EPS of $0.65, down from $0.68 a year earlier. Even so, ongoing 2026 EPS is still tracking in the upper half of the $3.36 to $3.46 range despite roughly a $0.03 weather hit. The headline miss was small, but more important, it did not clearly damage the full-year earnings setup.

The longer-term commitment is also clearer. Alliant expects compound annual earnings growth of 7% plus across 2027 through 2029, while also outlining $2.4 billion of common equity needs through 2029. That points to a utility preparing to expand its asset base faster in order to support future earnings from new infrastructure tied to rising demand.

That is also where the debate begins. Bulls see real project momentum, with three large-load projects already under construction and management highlighting accelerating electricity demand from large customers, including data centers. Bears are focused on two conditions: that the load materializes on schedule and that cost recovery follows through with regulators, not just inside the contract pipeline. If both hold, the growth plan looks credible. If not, more investment can become a capital burden faster than an earnings engine.

Alliant's data-center growth model depends on conversion, not just demand

Alliant says sixty percent demand growth by 2031 is tied to five executed electric service agreements with large-load customers, primarily data-center developments. That makes the next earnings call important: the story works best if signed agreements keep moving from contract to energization to rate-supported cash flow.

Why the project pipeline matters more than small retail-sales swings

The basic logic is straightforward. A large customer does not need to move retail sales very much for Alliant to benefit. What matters is that the customer connects to the grid, helps fund the dedicated upgrades, and allows those capital costs to enter rate base. That is a different dynamic than relying mostly on small changes in household electricity use.

Alliant has said new large-load customers should pay their own cost of service. However, the cited evidence does not support earlier language suggesting that approach could extend the rate freeze beyond 2029 in Iowa, so that phrase has been removed. If pay-through mechanisms and regulatory approvals continue to work, contracted load can translate into steadier regulated revenue.

Construction progress is real, but timing is still the test

This is not just a prospectus story anymore. Alliant says three large-load projects are already under construction, and management has said expected demand from large customers remains on track to materialize this year. That gives investors a more concrete way to judge progress: are projects moving from planning into energization, into revenue requirements, and into earnings on schedule?

Financing lowers the friction, but it does not remove the risk

The capital plan also shows Alliant is preparing to build. The company has raised about $1.8 billion of its $2.4 billion common equity need through 2029, leaving approximately $500 million to be raised through 2029. It has also outlined up to $800 million of long-term issuances for 2026, while approximately $50 million in Department of Energy grants should help, though grants do not drive the core earnings engine.

That keeps the debate alive. If pay-through and approvals stay on track, investors are funding a larger asset base that can turn relatively quickly into regulated returns. If either slows down, spending can rise before the earnings payoff does.

What bulls and bears are actually arguing about

The key issue is not whether data-center demand exists. It is whether that demand converts into a durable regulated cash stream quickly enough to justify the build.

What bulls are really buying

Bulls are not just betting on more load. They are betting that Alliant can continue the pattern of regulated growth it has shown in recent years. In 2025, ongoing EPS grew 6%, and management reaffirmed the $3.36 to $3.46 2026 range even after a softer quarter. Alliant also said three large-load projects are already under construction under commission-approved contracts, with progress reported on sites tied to Google, QTS, and Meta.

That makes the thesis more concrete than a pure narrative. If the chain from contract to construction to energization to rate base holds, future growth has more behind it than future headlines.

What bears are challenging

Bears are less focused on direction than on timing and quality. Rising demand is one thing; cash in the register is another. The model still depends on pay-through and cost recovery showing up in rates on schedule, not just on signed agreements. The financing ledger also matters. Alliant has secured about $1.8 billion of its $2.4 billion common equity need through 2029, and it has approximately $500 million to be raised through 2029.

That leaves a clear bear case: if project timing or regulatory timing slips, investors may be funding a bigger asset base before the earnings benefit arrives.

What the next call needs to confirm

The next earnings update matters less as a routine report and more as a roadmap check. Investors should look for three things: - whether near-term demand continues to materialize this year, as management said expected demand from large customers remains on track to materialize this year - whether the contract pipeline keeps converting into buildable, rate-supported work - whether execution remains clean enough to protect the growth model from financing and timing friction

That is the real decision point: not whether Alliant can build, but whether it can build into regulated cash flow quickly enough to justify the story.

The dip is interesting, but the wait-and-see case is still strong

For now, the setup still looks more like a watchlist opportunity than a trigger-hungry buy.

What would improve the case

The buy-the-dip argument gets stronger if updates show the pipeline keeping pace with the construction story. Alliant says three large-load projects are already under construction, and the company has said expected demand from large customers remains on track to materialize this year. More updates like that would make the story look less like a concept and more like a build-out with visible milestones.

What would keep it in wait-and-see territory

The negative read-through is fairly easy to spot: softer language on regulatory milestones, slower customer ramp timing, or financing that starts to look rushed rather than prepared. Alliant still has approximately $500 million to be raised through 2029 and has outlined up to $800 million of long-term issuances for 2026. If execution drags, that capital plan looks less flexible and more pressured.

A simple way to frame the decision

Stay more cautious if: - projects remain advanced but do not bring fresh approval or energization updates - management softens its message on when large-customer demand will materialize - financing language shifts from prepared to urgent

If those signals stay constructive, the dip becomes easier to respect. If not, the wait-and-see case still looks reasonable.
