SBC to FCF

Capital returns

Stock-based compensation as a share of free cash flow in the latest fiscal year.

Formula

SBC/FCF = stock-based compensation ÷ free cash flow (when FCF is positive)

Why it matters

Stock compensation is a real expense paid in ownership instead of cash. Because it is added back in the cash-flow statement, reported FCF overstates what accrues to existing shareholders whenever SBC is large: the cash looks free, but part of it was effectively raised by printing new shares. This ratio measures how much of the headline free cash flow is offset by that issuance. It matters most at technology companies, where SBC can quietly consume a third or more of FCF.

What good looks like

Below 15% of FCF is modest and earns quality-score credit. 15–30% is significant — mentally haircut the FCF yield accordingly. Above 30% triggers our red flag: at that level, buybacks often exist mainly to mop up compensation issuance, and 'free' cash flow materially overstates owner earnings.

Caveats

SBC expense is a grant-date accounting estimate; the true cost to holders is the shares actually issued, which is why this ratio should be read together with the share-count change. Cutting SBC is not free either — the company would otherwise pay cash salaries, lowering OCF. A high ratio caused by temporarily depressed FCF (denominator) is different from one caused by aggressive granting (numerator).
