1. Earnings Preview

Key Takeaway: The setup is broadly in-line with a modest beat potential, with the primary swing factor being the pace of data center load ramp and any incremental pipeline announcements that could signal upside to the Q3 resource plan refresh.

Heading into Q2 2026, the bar for LNT appears achievable but not particularly low. Consensus ongoing EPS sits at $0.585 for the quarter — a step-down from the $0.692 estimate that prevailed immediately after Q1 earnings, reflecting a notable downward revision in mid-to-late July (likely driven by weather normalization assumptions and seasonal patterns). Management reaffirmed full-year 2026 guidance on the Q1 call and has given no indication of a guidance change since, leaving the tone constructive and unchanged. Estimate revisions have been modestly negative in the final weeks before the print, with the Q2 consensus slipping from $0.692 to $0.585 between early May and late July, though the full-year 2026 consensus of $3.42 has been remarkably stable — suggesting the street views the Q2 softness as timing rather than structural. The stock has pulled back roughly 6.7% over the past month (from ~$77 to ~$72), underperforming both XLU and the S&P 500 in that window, which may reflect some de-risking ahead of the print rather than a fundamental re-rating. The single biggest wildcard is the Q3 resource plan refresh: management explicitly flagged on the Q1 call that the Q3 update will incorporate incremental load beyond the 3 GW already in the plan and updated MISO accreditation assumptions — any early signal on the magnitude of that upside, or a new ESA announcement, could be the decisive catalyst for the stock on results day.

2. KPIs & Consensus Expectations

Key Takeaway: Consensus sets a modest bar on EPS given seasonal Q2 softness; the bigger swing factor is whether data center load ramp commentary and rate base trajectory signal upside to the full-year and 2027–2029 growth outlook.

Pattern: LNT has beaten ongoing EPS consensus in 7 of the last 8 quarters, with the sole miss in Q3 2025 driven by weather headwinds; revenue beats are less consistent, with two misses tied to timing of large customer load ramp. The consistent EPS beat pattern suggests management guides conservatively.

3. Guidance & Commentary Evolution

Key Takeaway: Full-year 2026 guidance was reaffirmed on the Q1 2026 earnings call (April 30, 2026) with no subsequent revisions; management tone remains constructive, with the key forward catalyst being the Q3 resource plan refresh.

Key forward catalyst. Management: “Our third quarter update will include a refreshed Iowa resource plan, reflecting any incremental load beyond the 3 gigawatts already in our plan.”

4. Guidance vs. Estimate Revision Tracker

Key Takeaway: Q2 2026 EPS estimates have been revised down materially since the Q1 print (from $0.692 to $0.585, −15.4%), while the full-year 2026 consensus has been remarkably stable at ~$3.42 — suggesting the street views Q2 softness as seasonal timing, not a structural change. The gap between Q2 consensus and the full-year run-rate implies a back-half weighted earnings profile consistent with management’s historical pattern.

The sharp Q2 EPS revision (−15.4%) reflects seasonal normalization and weather assumptions rather than any guidance change — the full-year consensus has barely moved (+0.0%), confirming the street is simply re-phasing earnings within the year. The Q3 resource plan refresh remains the key event that could drive upward revisions to FY 2027+ estimates.

5. Stock Performance

Key Takeaway: LNT outperformed XLU and the S&P 500 for most of the post-Q1 period on data center momentum, but has given back gains in the final month ahead of the print — the recent pullback appears sentiment/de-risking driven rather than multiple-driven, as the NTM P/E of ~20.7x remains at a modest premium to the utility peer group average.

Since the Q1 2026 earnings date (April 30, 2026), LNT rose from $73.43 to a peak of ~$78.03 (July 2) before pulling back to $73.79 as of July 28, 2026 — a net change of approximately +0.5% over the full period. By contrast, XLU (the utility sector ETF used as the sector benchmark) declined modestly over the same window, and the S&P 500 gained approximately +3.1%. The stock’s 1-month performance of −6.7% underperforms both benchmarks, consistent with pre-earnings de-risking. Over the 12-month window, LNT is up +12.8%, with the NTM P/E multiple expanding from ~19.5x to ~20.7x — suggesting roughly half of the 12-month return has been multiple-driven, reflecting the market’s growing acceptance of the data center growth narrative. The current NTM P/E of 20.7x represents a ~14% premium to the utility peer group mean of ~18.1x, which is above LNT’s 3-year average premium of ~2.6%, indicating the stock is pricing in above-average growth expectations.

6. Peer Commentaries / Read-Throughs (Last 60 Days — Q2 2026 & Forward Outlook Only)

Key Takeaway: Peers reporting Q2 2026 results this week (NEE, WEC, ETR, DTE, CMS, FE) collectively reinforce three themes directly relevant to LNT: (1) data center demand is accelerating and pipelines are growing, (2) regulatory frameworks protecting existing customers from large-load cost shifts are being codified and are constructive, and (3) weather was a modest headwind in Q2 but full-year guidance is being reaffirmed across the board — all of which support LNT’s own guidance reaffirmation and data center growth narrative.

Note: Only commentary from Q2 2026 earnings calls (reported July 22–29, 2026) and post-Q1 2026 developments (since May 30, 2026) is included below. Prior-quarter results commentary has been excluded.

7. Material News & Developments (Since April 30, 2026)

Key Takeaway: The most important development since Q1 earnings is the April 2026 signing of a new 370 MW hyperscale ESA in Iowa, bringing total contracted demand to ~3.4 GW — a 60%+ increase in peak demand — and setting up the Q3 resource plan refresh as the next major catalyst for upward estimate revisions.

8. Insider Transaction Activity

Key Takeaway: No open-market insider purchases or discretionary sales were identified for LNT in the period since the Q1 2026 earnings release (April 30, 2026). The absence of insider buying is not unusual for a regulated utility with a stable, well-telegraphed growth outlook; the absence of discretionary selling is a mild positive signal.
