The business, in plain English

Spire Inc. booked $2.5B of revenue in FY2025 in the Utilities sector and kept 58.8% of it as gross profit — a high-margin business by that measure. After every other cost, 11.0% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $1.6B (FY2011) to $2.5B (FY2025) — about 3.3% a year compounded over 14 years.

It earned 5.0% on invested capital in FY2025, with a median of 5.2% across 18 filed years. The Returns on Capital filter above scores it 0/100.

The balance sheet carried $5.2B of total debt in FY2025 against $271.7M of owner earnings — roughly 19.0 years of owner earnings to retire it all. Balance-Sheet Safety scores it 1/100.

The share count rose 36.6% between FY2014 and FY2025 — existing owners have been diluted over the record. Capital Discipline scores it 43/100.

Put together: Pricing Power is the strongest of the four filters (80/100) and Returns on Capital the weakest (0/100), which is how SR lands at 33/100 — a None moat.
