The business, in plain English

SILICON LABORATORIES INC. booked $784.8M of revenue in FY2025 in the Technology sector and kept 58.2% of it as gross profit — a high-margin business by that measure. After every other cost, −8.3% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $415.6M (FY2008) to $784.8M (FY2025) — about 3.8% a year compounded over 17 years.

It earned −7.6% on invested capital in FY2025, with a median of 6.9% across 18 filed years. The Returns on Capital filter above scores it 7/100.

The balance sheet carried $72.5M of total debt in FY2016. Balance-Sheet Safety scores it 28/100.

The share count fell 28.0% between FY2009 and FY2025 — management has been retiring shares, which concentrates each remaining owner's claim. Capital Discipline scores it 64/100.

Put together: Pricing Power is the strongest of the four filters (97/100) and Returns on Capital the weakest (7/100), which is how SLAB lands at 50/100 — a Shallow moat.
