19 years of fundamentals

The business, in plain English

KAISER ALUMINUM CORP booked $3.4B of revenue in FY2025 in the Industrials sector and kept 13.1% of it as gross profit — a thin-margin business by that measure. After every other cost, 3.3% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $1.5B (FY2008) to $3.4B (FY2025) — about 4.8% a year compounded over 17 years.

It earned 7.5% on invested capital in FY2025, with a median of 7.5% across 18 filed years. The Returns on Capital filter above scores it 25/100.

The balance sheet carried $1.1B of total debt in FY2025 against $112.5M of owner earnings — roughly 9.4 years of owner earnings to retire it all. Balance-Sheet Safety scores it 13/100.

The share count fell 20.1% between FY2009 and FY2025 — management has been retiring shares, which concentrates each remaining owner's claim. Capital Discipline scores it 62/100.

Put together: Capital Discipline is the strongest of the four filters (62/100) and Pricing Power the weakest (1/100), which is how KALU lands at 23/100 — a None moat.
