Optimistic top

Idt Corp-Class B (IDT): Two methods value the business — a conservative owner-earnings DCF and a growth-credited Greenwald estimate, $25–$162 / sh. Today’s price sits below both (price $81 as of 2026-10-16).

The middle figure is the main read. The right end is the optimistic case under the same conservative caps — not an absolute ceiling.

Method & numbers

Model cautions

  • The two methods’ midpoints differ materially — growth assumptions warrant review (over 20%).
  • Growth nearly matches the discount rate — the estimate is sensitive to assumptions.

A conservative intrinsic-value band (zero-growth floor to growth-capped DCF) plus a tangible asset floor — not investment advice, not a buy/sell signal, and not a price target.

Owner-earnings DCF $38.20 – $162.42 · Greenwald $53.85 – $113.75 (neutral $86.35) · zero-growth base $39.86 · reproduction $19.88

Moat Franchise (moat) · terminal value 33% of present value · owner-earnings yield 3% vs 10Y 5.1%.

Graham earnings-power value (normalized NOPAT)$34.21 – $39.86 / sh

Normalized NOPAT = average operating margin over the years shown × latest-year revenue × (1 − normalized tax); then + D&A − maintenance capex (write A). Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge applied: + cash − total debt.

Years: 2026, 2025, 2024, 2023, 2022

v1 simplifications: Maintenance capex (degraded) deducted in full cash (write A): EPV = (NOPAT + D&A − maintenance capex) / WACC; no tax shield on the capex term. Maintenance-capex methods diverge by 82% (> 50%); estimate is degraded. Share-based compensation is left as a real expense (not added back).

Buffett owner-earnings value$25.14 – $30.73 / sh

Owner earnings = average net income + average D&A − maintenance capex (zero-growth floor; no ΔNWC). Levered (starts from net income, already after interest — an equity-holder stream). Capitalized at the 9–11% rate band (read as a cost-of-equity proxy). No enterprise→equity bridge: the capitalized result is already equity value (subtracting debt would double-count interest).

Years: 2026, 2025, 2024, 2023, 2022

v1 simplifications: Owner earnings = net income + D&A − maintenance capex (degraded); the working-capital change is excluded (maintenance ΔNWC ≈ 0; growth ΔNWC is carried in growth value, not double-counted). Maintenance-capex methods diverge by 82% (> 50%); estimate is degraded. One-time items are not separately normalized (multi-year averaging smooths them partially). Share-based compensation is left as a real expense (not added back); see the SBC/OE disclosure. Capitalized at the 9–11% band as a cost-of-equity proxy; no leverage premium applied (net cash or debt within the no-charge range).

Reproduction value = tangible net assets $342.02M + capitalized R&D $155.45M（FY 2026, 2025, 2024, 2023, 2022） = $19.88 / sh. Reproduction value = tangible net assets (equity − goodwill − intangibles) + capitalized R&D (5y straight-line), ÷ diluted shares.

Moat reading: Franchise test compares earnings power (EPV) against reproduction value on both AV_conservative (tangible + capitalized R&D) and AV_reproduction (conservative + acquired-reset proxy). Both must clear the franchise multiple for a moat signal; near it, a commodity; below it, value destruction. A directional reading, not a verdict.

Assumes a wide moat · competitive-advantage period ≈ 20 years (earnings intact, ROIC stable over history).

Growth value: if the moat holds for 20 yr at ROIIC ≈ 52%, $13.99–$73.90 / sh (neutral $46.49). Conservative, not a forecast.

Window FY 2026, 2025, 2024, 2023, 2022 · discount band 9%–11% · normalized tax 17% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.

Owner-earnings DCF: growth g₁ 20% · OE FY 2026, 2025, 2024, 2023, 2022 · Discount band: 9.60%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-10-15). No enterprise→equity bridge: owner earnings already flow to shareholders (post-interest), so no net cash is added and no debt subtracted — matching the engine owner-earnings lamp. Two-method midpoint gap 41%.
