Columbia Financial stock has delivered a strong 72.5% return over the past year, yet the valuation checks still lean expensive, which raises questions about how much of the recent good news is already in the share price.

• The 72.5% one year gain suggests investors have quickly priced in a more optimistic outlook for Columbia Financial.
• The completed mutual-to-stock conversion, large US$1.7b offering and pending Northfield Bancorp merger can support scale and capital deployment, but also add integration and execution risk that may affect how sustainable current expectations are.
• Columbia Financial scores 0 out of 6 on the broader valuation checks, which points to a stock that does not screen as a clear bargain on standard valuation metrics (0/6 valuation score).

The issue now is whether Columbia Financial's current share price already reflects most of the benefits from its conversion and merger, or if there is still room for further upside without valuation becoming overly stretched.

Is Columbia Financial Getting Expensive on Earnings?

The P/E ratio is often the cleanest way to think about what you are paying today for Columbia Financial's current earnings power. For a bank, that earnings anchor is especially useful because it ties directly to the core lending and fee businesses.

Columbia Financial currently trades on about 52.9x earnings, which sits well above the Banks industry average of roughly 11.9x and also ahead of the peer group average of about 15.2x. The fair P/E that a tailored model suggests for Columbia Financial, which factors in its size, risk profile and sector, is closer to 38.0x. That still implies a meaningful gap between the current market price and what this framework treats as a reasonable earnings multiple.

The recent completion of the mutual to stock conversion, the US$1.7b offering and the Northfield Bancorp deal appear to have supported strong sentiment, yet the present P/E already reflects a full valuation against both industry norms and this adjusted fair ratio.

On the P/E multiple, Columbia Financial stock currently screens as fully valued relative to both its sector and a more tailored fair value benchmark.

The Bottom Line

Columbia Financial now trades on a P/E that sits well above both sector averages and a tailored fair multiple, so the stock currently screens as overvalued on market multiples. The low value score reinforces that broader valuation checks do not point to an obvious bargain. From here, the key debate is whether future progress on deploying fresh capital and integrating the Northfield Bancorp merger can support this richer multiple, or whether expectations eventually cool and the valuation settles closer to banking peers.
