International Bancshares Crp (IBOC): A conservative value band $52–$113 / sh (zero-growth floor to growth-capped optimistic top); central read about $92. Today’s price sits below that band (price $71 as of 2026-08-21).
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
Operating income is not reported separately (e.g. banks, insurers, and some diversified issuers), so earnings power is shown via the owner-earnings lens only; the unlevered NOPAT lens does not apply.
Model cautions
- Owner-earnings yield diverges sharply from the 10-year Treasury (over 300 bps).
- 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 $57.12 – $113.17 · Greenwald zero-growth $63.80 · zero-growth base $63.80 · reproduction $47.69
Moat Commodity-like · terminal value 50% of present value · owner-earnings yield 8% vs 10Y 4.7%.
Graham earnings-power value (normalized NOPAT)
Operating income is not reported separately (e.g. banks, insurers, and some diversified issuers), so earnings power is shown via the owner-earnings lens only; the unlevered NOPAT lens does not apply.
Normalized NOPAT from operating margin — not applicable when operating income is not reported separately. Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge (+ cash − total debt) — not applied (lens not assessable).
Years: 2025, 2024, 2023, 2022, 2021
Buffett owner-earnings value$52.20 – $63.80 / 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: 2025, 2024, 2023, 2022, 2021
v1 simplifications: Maintenance capex or D&A unavailable → degraded to normalized net income (= average net income over the years shown). 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. Financial issuer (bank/insurer): net debt / owner earnings does not describe a deposit-funded balance sheet, so no leverage premium is applied here; leverage is instead handled by the reliability gate.
Reproduction value = tangible net assets $2.97B = $47.69 / sh. Tangible net assets = shareholders' equity − goodwill − intangibles, ÷ diluted shares (no R&D history to capitalize).
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.
Growth value gated to zero — no moat or ROIIC ≤ WACC, so no growth value is credited.
Window FY 2025, 2024, 2023, 2022, 2021 · discount band 9%–11% · normalized tax 21% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.
Owner-earnings DCF: growth g₁ 7% · OE FY 2025, 2024, 2023, 2022, 2021 · Discount band: 9.19%–12.00% (DGS10 +4.5% to a 12% strict end, as of 2026-08-20). 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.
