When is LNT’s next earnings date?
Friday, November 6, 2026estimated
Expected around Nov 6 — based on last year’s report on Nov 7, 2025. We have not yet seen the company's announcement of the date.
How we estimate
The estimate is the date of the same-quarter report a year ago, per the company’s SEC filing, moved forward 52 weeks (same weekday). Companies usually keep the same week; the date will be replaced once LNT announces it.
Same quarter a year ago (ended September 30, 2025): revenue $1.21B, EPS (GAAP) $1.09
How we calculate
Year-ago figures are GAAP, from the company's SEC filings (XBRL); EPS is diluted.
What time does LNT report? Usually before market open: the last 4 results releases reached the SEC at 6:02 pm, 6:23 pm, 6:22 pm, 6:10 pm ET, each the evening before the release.

How we calculate
Figures are annual report lines; if a year was later restated (discontinued operations, mergers), we use the latest filing that shows it. Free cash flow is operating cash flow minus capital expenditures; dividends are cash paid to common shareholders during the year. “—” means the line isn’t in the filing. The table starts in 2011; where the listed issuer changed (holding reorganization, redomicile), earlier years come from the predecessor’s filings.
