Net Debt (used)$174.32M

Sensitivity: WACC (rows) × Near-term g (cols)

2 — Graham Number

Assumptions

MultiplierGraham used 22.5 (15× P/E × 1.5× P/B)

EPS (trailing)($)Yahoo: $7.62

Book Value / share($)Yahoo: $41.92

Results

Graham Number$84.78

Current Price$72.40

Margin of Safety+17.1%

Formula: √(22.5 × max(0,EPS) × max(0,BVPS))

3 — Reverse DCF (Implied Growth)

Assumptions

WACC(%)Computed: 13.73%

Terminal growth rate(%)

Computed WACC: 13.73%

Cost of equity (Re)15.16%(Rf 4.30% + β 1.98 × ERP 5.50%)

Cost of debt (Rd)0.00%(no debt / unavailable → 0%)

Tax rate (T)21.00%(US statutory fallback)

Equity weight (E/V)90.56%

Debt weight (D/V)9.44%

Results

Current Price$72.40

Implied Near-term FCF Growth32.6%

Historical Revenue Growth-2.6%

Historical Earnings Growth-23.0%

Base FCF (TTM)$80.06M

Implied growth is the FCF growth rate (yrs 1–5) that makes the DCF intrinsic value equal the current price. Long-term growth is set to half the implied near-term rate.

4 — Dividend Discount Model (DDM)

Assumptions

Annual dividend D0($/share)Yahoo: —

Dividend growth rate (g)(%)

Required return (r)(%)

Results

This company does not pay a dividend. DDM is not applicable — the intrinsic value shown uses D0 = $0 unless you enter a hypothetical dividend above.

DDM Intrinsic Value / share—

Current Price$72.40

Upside / Downside—

Formula: D0 × (1+g) / (r − g)

5 — EV/EBITDA Multiple

Assumptions

EBITDA($B)Yahoo: $414.55M

Target EV/EBITDA multipleCurrent: 8.3×

Net Debt($B)Default: $174.32M

Results

Implied Equity Value / share$74.51

Current Price$72.40

Upside / Downside+2.9%

Implied EV$3.42B
