The business, in plain English

SIRIUS XM HOLDINGS INC. booked $8.6B of revenue in FY2025 in the Communications sector and kept 52.4% of it as gross profit — a solid-margin business by that measure. After every other cost, 9.4% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $1.7B (FY2008) to $8.6B (FY2025) — about 10.1% a year compounded over 17 years.

It earned 5.3% on invested capital in FY2025, with a median of 14.8% across 17 filed years. The Returns on Capital filter above scores it 86/100.

The balance sheet carried $9.7B of total debt in FY2025 against $805.0M of owner earnings — roughly 12.1 years of owner earnings to retire it all. Balance-Sheet Safety scores it 3/100.

The share count fell 91.4% between FY2009 and FY2025 — management has been retiring shares, which concentrates each remaining owner's claim. Capital Discipline scores it 40/100.

Put together: Returns on Capital is the strongest of the four filters (86/100) and Balance-Sheet Safety the weakest (3/100), which is how SIRI lands at 53/100 — a Shallow moat.
