The business, in plain English

Across the filed record, revenue grew from $3.2B (FY2008) to $5.3B (FY2025) — about 3.0% a year compounded over 17 years.

It earned 5.2% on invested capital in FY2025, with a median of 6.2% across 18 filed years. The Returns on Capital filter above scores it 2/100.

The balance sheet carried $10.6B of total debt in FY2025 against $631.6M of owner earnings — roughly 16.7 years of owner earnings to retire it all. Balance-Sheet Safety scores it 1/100.

The share count rose 11.1% between FY2010 and FY2025 — existing owners have been diluted over the record. Capital Discipline scores it 33/100.

Put together: Pricing Power is the strongest of the four filters (100/100) and Balance-Sheet Safety the weakest (1/100), which is how PNW lands at 38/100 — a None moat.
