Plain-Language Summary

Warnings

⚠ Traditional cash flow models don't work well for banks — lending activity distorts how much cash the business actually generates.

⚠ Common valuation shortcuts don't apply here — for banks, interest payments are a core business cost, not overhead.

ℹ Dividend-based valuation: $14.32 (41% below our primary estimate). Large gaps suggest the dividend may not fully reflect the company's value.

Key Risks

Book value quality matters as much as level — check loan loss reserves
Interest rate sensitivity creates non-linear earnings surprises
Insurance reserving is actuarial, not financial — errors emerge slowly
