2 — Graham Number

Assumptions

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

EPS (trailing)($)Yahoo: $-0.42

Book Value / share($)Yahoo: $15.86

Results

Graham Number requires positive EPS and positive Book Value per share. EPS is zero or negative.

Graham Number—

Current Price$27.99

Margin of Safety—

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

3 — Reverse DCF (Implied Growth)

Assumptions

WACC(%)Computed: 9.62%

Terminal growth rate(%)

Computed WACC: 9.62%

Cost of equity (Re)10.06%(Rf 4.30% + β 1.05 × ERP 5.50%)

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

Results

Current Price$27.99

Implied Near-term FCF Growth2.0%

Historical Revenue Growth0.8%

Historical Earnings Growth—

Base FCF (TTM)$41.21M

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$27.99

Upside / Downside—

Formula: D0 × (1+g) / (r − g)

5 — EV/EBITDA Multiple

Assumptions

EBITDA($B)Yahoo: -$2.04M

Target EV/EBITDA multipleCurrent: -279.4×

Net Debt($B)Default: -$262.49M
