Valuation X-Ray

Asset, earnings-power and peer-multiple models all land far below the price; ONLY the growth-DCF reaches it. The bet is durable compounding the static frames structurally cannot price (a moat/durability premium).

How the valuation models price the stock relative to the market price. Price/FV above 1.0 means the market pays more than that lens defends (expensive); at or below 1.0 the lens can defend the price.

Solvency

FieldValue
Share count CAGR (buyback)-0.6%

Deposit/float-funded balance sheet: debt is funding, not corporate leverage, and GAAP operating cash flow follows loan flows. Net-debt, interest-coverage, and cash-burn lenses do not apply. The solvency frame for a financial is regulatory capital and payout capacity (CET1, stress buffer, dividends plus buybacks against earnings).

Bullet Takeaways

Bull Case

Begin with the bear case, because it is the obvious objection: on standard bank math, Columbia Financial looks expensive. The price-to-tangible-book model justifies only about $5.25, since the return on equity near 4.8% is roughly half the cost of equity, and the stock trades at $20.05 (June 27, 2026), nearly 1.7 times its tangible book value of $11.57. A thrift earning well below its cost of capital should trade at a discount to book, not a premium. So the first question is whether the data undermines that fear or supports it, and the answer is that the earnings trajectory is doing real work to close the gap.

The recovery is underway and it is in the right line. Q1 2026 net income rose 47% to $13.1 million, net interest income grew 20% to $60.4 million, and the net interest margin expanded to 2.42% from 2.11% a year earlier. For a savings bank, margin is the engine, and the improvement came from both higher interest income and lower interest expense as deposit costs eased. The filing shows the same direction over the year, with net interest margin widening as funding pressure receded (FY2025 10-K, accession 0001723596-26-000010). A bank moving its ROE up from a depressed base is exactly the setup where the price-to-tangible-book multiple expands, because the justified multiple is a direct function of ROE relative to the cost of equity.

The forward-looking methods give the bull thesis its anchor. If Columbia continues normalizing its margin toward peer levels, the earnings power that the static P/TBV model cannot yet see materializes, and the premium to book becomes justified rather than speculative. A buyer at $20.05 is paying for that margin recovery to continue and for the franchise value of an established New Jersey deposit base, which a pure trough-earnings model understates.

Bear Case

The structural issue sits in the capital and earnings base, and it is the heart of the bear case. Columbia is a small thrift earning a return on equity of just 4.8%, far below its roughly 9.3% cost of equity, which means it is destroying economic value at the current run rate even after the recent improvement. A net interest margin of 2.42% is thin even for a savings bank, the legacy of a balance sheet heavy in lower-yielding, longer-duration assets funded by deposits whose cost rose sharply in the rate cycle. That asset-liability profile is the fragility: if deposit competition forces funding costs back up, or if long rates move adversely, the margin recovery stalls and the sub-cost-of-equity returns persist.

The deposit side is where the pressure shows. The filing notes significant competition in attracting deposits against many of the nation's largest institutions (FY2025 10-K, accession 0001723596-26-000010), and Q1 already reflected a $72.1 million deposit decline. A bank that is shrinking deposits while trying to expand margin is walking a fine line; deposits are the raw material, and losing them limits the earning-asset base. The New Jersey market is competitive and the local unemployment rate has been rising, to 5.4% by December 2025 against a 4.4% national rate, which pressures both loan demand and credit quality.

The valuation simply has no fundamental support at this price. The price-to-tangible-book model says $5.25, the simple excess-return method $5.96, and the earnings-yield read $5.95, a tight cluster around a quarter of the stock price. The reverse-DCF flags the price as a high-rarity outlier, with both the own-history and peer-cohort checks tripped, meaning the market is paying a multiple that neither Columbia's past nor its peers justify on earnings. The most plausible explanation is the company's mutual-holding-company structure, which leaves a partial public float trading on the prospect of a future conversion or sale rather than on profitability. That is a corporate-action wager, not an earnings story, and if the structural catalyst does not materialize the price is exposed to gravity back toward the low-single-digit fundamental value.

Valuation

Columbia Financial is valued as a bank, on tangible book and return on equity rather than cash-flow methods, which are skipped as not meaningful for financials. The anchor is the price-to-tangible-book model, which lands at just $5.25: tangible book per share of $11.57 multiplied by a justified 0.45x, where the low multiple reflects a return on equity near 4.8% against a 9.3% cost of equity, with a further haircut for credit allowance. The other fundamental frames agree, simple excess-return at $5.96 and earnings yield at $5.95, all roughly a quarter of the $20.05 price.

The reverse-DCF makes the disconnect explicit: it reads the price as a high-rarity outlier with both the own-history and peer-cohort checks tripped, an own-Z of 3.36 standard deviations above the norm. In plain terms, the market is paying far more relative to fundamentals than Columbia's own record or its regional-bank peers support.

The honest synthesis is that Columbia trades at a large premium to any earnings-based bank valuation, and the premium is explained by structure and a recovery bet, not by current profitability. The franchise has a real, improving margin story, the 2.42% NIM and 47% net-income growth are genuine, but even the improved returns do not justify nearly 1.7 times tangible book on a fundamental basis. The bet a buyer makes at $20.05 is twofold: that the margin recovery pushes ROE toward the cost of equity, and that the mutual-holding-company structure eventually resolves through a conversion or sale that crystallizes franchise value. If both happen, the high-growth methods are vindicated. If neither does, the fundamental cluster near $5 to $6 is the anchor the price has departed from.

Catalysts

The Q1 2026 report was the most recent catalyst and a constructive one: net income up 47% to $13.1 million, net interest income up 20% to $60.4 million, net interest margin expanded to 2.42% from 2.11%, and a lower provision for credit losses, partly offset by a $72.1 million deposit decline and higher expenses. The next quarter tests whether the margin expansion continues as deposit costs stabilize.

The forward watch items are specific to a small thrift. First, the net interest margin trajectory, the core earnings driver, where continued funding-cost relief would push the return on equity toward the cost of capital and justify more of the premium. Second, deposit trends, since the Q1 decline and intense local competition for funding constrain the earning-asset base. Third, credit quality, given a rising New Jersey unemployment rate that pressures loan performance. Fourth, and most decisive for the valuation, any corporate-action development tied to the mutual-holding-company structure, a second-step conversion or a sale, which is the most likely explanation for why the stock trades far above its earnings-based value. That structural catalyst, if it comes, is the event that would reconcile price and fundamentals; its absence leaves the premium unsupported.
