About this estimate

This calculator estimates what a bank or insurer could be worth today as its book equity plus the capitalised value of earning a return on that equity above its cost of equity. It is a general research and education tool. It is not personal financial advice, not a forecast of the share price, and it does not take account of your objectives or circumstances.

The result is highly sensitive to its inputs, especially the normalised return on equity and the gap between the cost of equity and the terminal growth rate. When that gap is narrow a small change moves it substantially. Treat the output as one estimate within a wide range, not a precise figure.

The estimate runs on a set of assumptions: a normalised return on equity, a cost of equity, and a terminal growth rate. Each one is shown in the assumptions panel below, and you can change any of them to test your own scenario.

The default assumptions are a reasonable starting point because they are derived from the company's own reported financials over a through-cycle window together with market-standard inputs, with the cost of equity built from the current government-bond (risk-free) rate, the company's beta, and a published equity-risk premium, and they are refreshed each data cycle. They are defaults for a neutral calculation, not our view of the right values for you.

This calculator is a research and education tool. It is not intended to be relied on for the purpose of making a decision about any financial product, and you should consider obtaining advice from a licensed financial adviser before making any financial decision.

Excess-Return Valuation

Residual-income (justified P/B) model for ISTR. This is the standard valuation lens for banks and insurers, whose value is driven by earning a return on book equity above its cost.

Model estimate & assumptions

Excess-Return Intrinsic Value

Per-share intrinsic value from the excess-return (residual income) engine.

Justified P/BIn line with estimate

Intrinsic (Excess Return)$25.60

Current price$28.82

Gap$3.22

Upside-11.2%

Basis: Book value & normalised ROE

ISTR's price is in line with this excess-return estimate. Its 7.8% normalised ROE sits below the 8.5% cost of equity, justifying a P/B of 0.84x against the current 0.94x. You can adjust these inputs in the Customize Parameters section.

Value Breakdown

Where the intrinsic value comes from: book value, plus the extra value created by earning a return above the cost of equity.

Book value per share$30.61

Excess-return shortfall−$5.01

-20% of intrinsic value

Intrinsic value per share$25.60

A bank or insurer is worth its book equity, plus or minus the value of earning a return above or below its cost of equity. Clear that hurdle and the premium is positive; fall short and the value sits below book.

Model details

Valuation Multiples

Per-metric breakdown of how ISTR is priced relative to its sector peers, its own 10-year history, and analyst forward estimates.

Valuation context: This company is valued the way banks and insurers are, on its equity and what it earns on it. Debt is raw material for these businesses, not financing, so the EV multiples are shown for comparison only. The estimates come from P/E, P/B (under Additional valuation multiples), P/S and free cash flow.

What sector peers imply

Value if it traded at the sector-median multiple

What its own history implies

Value if it traded at its own 10-year median multiple

How the Multiples lens works

Five primary multiples surface the headline call; five additional multiples sit one click deeper for context.

Valuation multiples compare a company's market price to its financial fundamentals. The primary grid covers both the equity perspective (P/E, PEG, FCF Yield) and the enterprise value perspective (EV/EBITDA, EV/FCF) so you see how the market prices the company two ways simultaneously.

Price-based multiples use market cap and reflect what equity investors pay. EV-based multiples include debt and are better for comparing companies with different capital structures. The expanded section below adds P/B, P/S, P/FCF, EV/EBIT, and EV/Sales for additional perspective.
