COLUMBIA BANKING SYSTEM, INC. (COLB) Stock Analysis
COLUMBIA BANKING SYSTEM, INC.
▾ What's in the 33/100 risk score? (higher = riskier)
Contributions (weight × component score) sum to the total. This near-term score now includes fundamental health (leverage, FCF trend, DCF applicability). It excludes the Altman Z score, whose retained-earnings input this filer does not report separately. See the Financial Health section for the full balance-sheet read.
Nothing we have tested argues against it, and one read argues for it. Worth reading further.
What "tested" means here, and why there is no score out of 100
Tested means the read was measured against what actually happened afterwards, on a history that keeps the companies that were later delisted, using only figures that had been filed on the day they are used. Survival was ranked on companies that really did fail. What an owner keeps was tested across the universe from 2011 to 2025. A valuation finding appears only when the cheap fifth of that business type beat the index — 156 of the 206 combinations we tried did not.
Not tested means we compute it and find it useful, but we have never measured whether it predicts anything. Our own model valuation is in that category. It is shown, and it does not decide the verdict.
There is no single score because we have not tested one. Combining five reads into one number implies somebody checked that the combination works, and nobody has. When that test exists, a number can appear here.

How to read COLB (bank / insurer)
Banks and insurers are valued on what they earn on their capital, not on free cash flow — a normal DCF misleads here.

Is now a good time to buy COLB?
Macro: Neutral / mid-cycleCOLB trades at $30.15 vs an estimated intrinsic value of $32.62 — a 7.6% discount to model IV.
Not investment advice. The model can be wrong. Verify the assumptions in the sections below and consider consulting a licensed advisor for significant decisions.
What return would COLB pay as a bond?
Not measurable here. Banks and insurers have no owner-earnings coupon in the operating sense — their deposits and float are the business. The bank lens (book value + return on equity) is the comparable read. See the cross-company ranking →

▾ The numbers, the logic, and why not to trade on it
The logic. A model trained on every US filing since 2012 — including 823 companies that went bankrupt or stopped trading under a dollar — ranks each covered stock by its chance of failing in the next year, from its latest filing, price history and credit conditions. The rank is a position among peers; the table is a count of what happened to stocks in each position, scored each year by a model that had not seen that year.
| Rank band | went bankrupt within 12 months | fell 80% or more (or failed) within 12 months | fell 50% or more (or failed) within 6 months |
|---|---|---|---|
| All covered stocks (average) | 0.59% | 4.21% | 8.51% |
| Finance (sector average) | 0.13% | 1.25% | 3.09% |
| riskiest 1% | 16.4% | 33.0% | 45.5% |
| next 2% (97-99) | 5.9% | 24.9% | 38.2% |
| next 2% (95-97) | 3.4% | 21.2% | 33.8% |
| next 5% (90-95) | 1.6% | 15.1% | 27.3% |
| next 15% (75-90) | 0.8% | 8.5% | 17.8% |
| next 25% (50-75) | 0.2% | 2.7% | 6.2% |
| safest half ← this stock | <0.1% | 0.5% | 2.1% |
Why not to trade on it. We tested shorting these names and buying puts, spreads, straddles and condors on them at real option prices, 2010–2025: every version lost money. The market already prices the distress, and the survivors squeeze. Use a high rank to read the filings and to size for a total loss — not to bet against the company. A low rank says the balance sheet is calm, not that the price is sensible.
Scored from the filing of 2026-05-06; table generated 2026-09-18. Within Finance: rank 3 of 100. Rough one-year odds for this stock alone: bankruptcy <0.1%, an 80% fall 0.2% (the model overstates the middle of the range).
▾ The logic, and why not to buy on it
The logic. Trained on 2,900 acquisitions since 2012, the model leans on size (small), age, retained earnings, asset growth, volatility and how many deals the sector has just seen. Announcement = the day the stock jumped, not the day the paperwork was filed.
| top 1% | 15.4% acquired within a year |
| next 2% (97-99) | 10.3% acquired within a year |
| next 2% (95-97) | 9.0% acquired within a year |
| next 5% (90-95) | 7.3% acquired within a year |
| next 15% (75-90) | 6.4% acquired within a year |
| next 25% (50-75) | 4.8% acquired within a year |
| bottom half ← this stock | 3.0% acquired within a year |
Why not to buy on it. A takeover paid a median +22% on the day — but even in the top band about 6 in 7 companies are not bought, and those lag. Buying the whole top list returned what the S&P 500 did (2012–2023), and adding "cheap" or "beaten-down" filters did not change that. Read it as context for a thesis you already have, never as the thesis.
Football field: where does the price sit?
Different valuation methods produce different fair-value ranges depending on assumptions. Plotting them together lets you see at a glance whether the current price is reasonable across approaches, or only one specific lens.
Industry multiples sourced from: industry: Banks. See the Peer Basket section below for the peer comparison and its limited-comparables caveat.
How does COLB stack up against its closest peers?
We take the 8 same-industry companies most similar to COLB (similar size) and check what investors are paying for each dollar of their revenue (or profits). If COLB is much more expensive on the same yardstick, that's a red flag — unless you have a specific reason it deserves a premium. For a leveraged business, FCF yield (in the table) is usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 8 same-industry peers; implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.

How to value a bank (not a DCF question)
A bank's economic engine is the shareholder equity on its balance sheet — what the accountants say is left over after all loans, deposits, and liabilities are netted out. The bank earns a percentage on that equity each year (its ROE). So the two questions are: (1) what are you paying per dollar of equity (Price / Book)? and (2) how much is that equity actually earning (ROE)? Free cash flow doesn't work here — banks lend out their cash for a living.
Why it matters: For banks and insurers, book value is the regulatory capital they earn returns on. P/B is the cleanest comparison: 1.0× means buying the bank at the same price the accountants say it's worth.
Reference: 0.8–1.2× = fair for average bank · 1.5–2.0× = solid franchise · >2.5× = premium · <0.8× = potentially cheap or distress
Full explanation →
Below $1 = you're paying less than the equity is "worth" on paper.
Why it matters: For a bank, ROE is the engine. A bank earning 15% on equity will compound book value at ~15%/year if it retains earnings. Combined with P/B, ROE tells you whether a premium price is supported by returns.
Reference: <8% = weak · 10–12% = solid · 15%+ = excellent · >20% sustained = exceptional franchise
Full explanation →
Why it matters: For banks especially, ROA isolates underwriting and operating efficiency from leverage. Two banks with identical ROE may have very different ROAs — one earning it cleanly, one earning it on borrowed money.
Reference: <0.8% = weak · 1.0–1.2% = solid · >1.5% = excellent (very rare for big banks)
Full explanation →
ROA differs from ROE because banks borrow ~10× their equity. Big asset base, smaller equity sliver.
Why it matters: High P/E = market expects fast growth or you are overpaying. Low P/E = market expects slow growth or the stock is cheap (sometimes for good reason).
Reference: 12–20 for mature businesses · 25–50 for growth · 80+ for speculative

Note: this lens skips Altman Z-Score and Piotroski F-Score (validated on industrial companies, not banks). For deeper bank-specific health analysis: check the 10-K's Tier 1 capital ratio, Non-Performing Loan ratio, and CET1 — these are what regulators actually monitor.
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
Altman Z was calibrated on industrial firms and doesn't apply to banks — the balance sheet is dominated by loans and securities, not working capital. See the Bank Valuation Lens above for P/TBV, ROTCE, P/B, ROE and ROA — the measures analysts in that industry actually use.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak
Full explanation →
Piotroski F was built for non-financial firms (gross margin, asset turnover and current ratio all assume an industrial cost structure). For banks the equivalent quality signals are the efficiency ratio, net interest margin and provision coverage — see the Bank Valuation Lens above.
What if you assume different inputs?
Here's where we land — and what happens if you change the assumptions. Drag the sliders to set your own Discount RateDiscount Rate — The annual return you demand for taking single-stock risk instead of buying a safe Treasury or index fund.
Why it matters: Higher discount rate = stricter valuation (a stock has to produce more cash to be worth holding). Lower = more generous.
Reference: 8–12% is standard · 9–10% matches S&P 500 historical return · Below 7% is illogical for single-stock risk
Full explanation → (the annual return you demand for single-stock risk) and terminal growth; the value updates live so you can see whether the stock looks cheaper or richer. The discount rate starts at 11.2%, the figure our model used for COLB. Open Advanced to also change beta, growth and the rate path.
Note: the calculator opens at our published value of $32.62 — it is initialised to the same scenario-weighted result, so the two match exactly on load. The moment you move a slider, the value below becomes a single-path what-if at your assumptions (not the three-scenario weighting), which is why it can differ from the headline once you've touched it.
11.2% — beta-based (CAPM), from this stock's BetaBeta — How much the stock moves when the overall market moves. 1.0 = moves with the market; 1.5 = moves 50% more than the market.
Why it matters: Higher beta = more volatile = should demand higher discount rate. Low beta stocks (utilities, consumer staples) move less.
Reference: Most stocks 0.5–1.5 · Defensives ~0.3 · High-vol tech ~1.5–2.0
Full explanation → of 1.22. The safe Treasury rate plus a premium scaled by how much more (or less) volatile the stock is than the market.
9.0% — sector/quality tier. A simpler hurdle set by industry and business durability: lower for stable, wide-moat companies; higher for speculative or micro-caps.
The headline value and this calculator start at 11.2% — the beta-based rate. Drag the slider to the other rate to see the full range.
A full intrinsic value isn't shown for COLB because it's valued with a bank residual-income model this quick calculator doesn't replicate — see our published value above and the sector lens for the right metrics.

COLB is fairly valued, trading at a 7.6% discount to the model's intrinsic valueIntrinsic Value — Our DCF model's estimate of what each share is mathematically worth based on projected cash flows.
Why it matters: Compare to current price. Below IV = potentially undervalued. Above IV = priced for growth that must actually happen.
Reference: Model-derived; quality depends on data and assumptions.
Full explanation → of $32.62. The market appears to be pricing in the company's moderate franchise durability score of 2/5, despite consistent profitability and revenue growth. The primary quantifiable risk is the potential for a decline in operating cash flow from its current positive trend.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Next quarter's net interest margin trend
- Growth in loan portfolio balances
- Changes in non-interest income
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Revenue grew +19% to $177.0M.
- Free cash flow rose to $713.0M.
- Net income grew +3% to $550.0M.
Nothing was clearly worsening year-over-year.

Why it matters: Compare to current price. Below IV = potentially undervalued. Above IV = priced for growth that must actually happen.
Reference: Model-derived; quality depends on data and assumptions.
Full explanation →, likely due to its moderate franchise durability score of 2/5. While revenue is growing at 20.7%/yr and operating cash flow is positive, the market may be cautious about the long-term competitive advantages in a crowded banking sector.
Three Scenarios, Weighted
| Scenario | IV | Upside from today's price | Weight |
|---|---|---|---|
| Conservative | $28.67 | -4.9% | 40% |
| Base | $33.90 | 12.4% | 35% |
| Optimistic | $37.13 | 23.2% | 25% |
| Weighted | $32.62 | 8.2% | 100% |
Reading the last column: it is the move from today's price to each value (IV ÷ price − 1). The headline "premium/discount to model IV" measures the same gap from the value's side (price ÷ IV − 1), so the two percentages differ in size and sign by construction — e.g. a price 8% above value is a value 7.4% below price.

What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project net interest income and fee-income lines independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.

Cash Flow (5yr)
Capital expenditure isn't tagged in this filer's machine-readable data (the CapEx column shows "—"). The free-cash-flow column is therefore operating cash flow less stock-based compensation only — an upper bound on true owner earnings, not the real figure. Companies that report capex under a custom label (some large IFRS filers do) look better here than they are.
| Year | Operating CF | CapEx | − SBC & adj. | Free Cash Flow |
|---|---|---|---|---|
| 2025 | 746.0M | — | 33.0M | 713.0M |
| 2024 | 659.0M | — | 20.0M | 639.0M |

| 2021 | 662.7M | 15.5M | 10.9M | 636.3M |
How we define FCF: operating cash flow − capital expenditure − stock-based compensation (owner-earnings basis — SBC is a real cost to shareholders even though it's non-cash). Latest year: 746.0M − — − 33.0M (SBC & adj.) = 713.0M. This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a EPS basis (residual-income model), not this single year.
