The reason KB Financial’s PBR has0.42from1to is not earnings.

When people talk about bank stocks, they mostly look first at dividend yield. The percentage paid is what becomes the screening criterion.

But if you try to explain KB Financial Group's past few years only through dividend yield, it does not add up.

PBR 0.42moved from 1below book value to above book value. Did bank profits double in the meantime?

No. That is why we framed this card news as 'capital, not earnings'.97C20C73.

First, let us look at what created the re-rating

Stock prices are calculated on a per-share basis. Even if earnings stay the same, if the number of shares falls, earnings per share and book value per share rise.

This is not something that happens because management is doing well; it happens because the denominator is being reduced.

KB Financial Group in 2026year carried out a total of 1trillion 2,000billion won in treasury share buybacks, and the 6,000billion won already repurchased was immediately canceled.

In addition, in 4month it resolved to cancel all existing treasury shares of 1,426ten thousand shares, worth about 2trillion 3,000billion won in full.

The effect this scale has on the stock price is different in nature from dividends.

You must keep in mind why cancellation is stronger than dividends

Dividends end once received in cash. If paid once in that year, that is the end of it. By contrast, cancellation permanently reduces the number of shares itself.

It is a structure in which the ownership stake of the remaining shareholders rises permanently.

In other words, dividends are a one-time cash transfer, while share cancellations are a permanent change to the capital structure. This is the point that is easy to miss for those who choose bank stocks by looking only at dividend yield.1Even if the same amount is spent, per-share value will differ years later depending on whether it goes out as dividends or through share cancellations.

While KB Financial Group’s PBR more than doubled, the banking industry itself did not change dramatically. What changed was the way capital was used.

Then what determines the limit of capital return?

This is the core of this article. Many people calculate a bank’s shareholder returns as profits. They look at net income and then think of giving out a certain percentage of it. That is not a wrong approach, but in banking there is one step missing.

Banks are a regulated industry. They cannot freely distribute the money they earn.1The standard is common equity capital ratio, that is, CET. Only when this ratio has room above the regulatory floor can excess capital be returned to shareholders.

KB Financial Group's CET1 is 13.63%, the highest level in the industry. 1Quarterly net income of 1trillion 8,924hundred million won is actually less important than this figure. Profit can fluctuate in a single quarter, but if CET1 is maintained, the capacity to continue returning capital remains. That is why we wrote on the card news, 'Bank stocks are bought not for earnings, but for CET1.'

2026year 1shareholder return for the 2trillion 8,200hundred million won. 1Quarterly dividend per share is 1,143won, up 25.3% from a year earlier, and annual cash dividends are expected to be around 1trillion 6,200hundred million won. These figures are the result of capital, not earnings, being allowed to support them.

So what should we be wary of?

The interesting thing is that what breaks this structure is not earnings, but capital.

First is interest rates. The group NIM is 1.99%, and bank NIM is 1.77%. In a rate-cutting cycle, net interest margin narrows. If earnings decline, the pace of capital accumulation also slows.

Second is credit loss. If credit-loss expenses rise as project finance tied to real estate or delinquencies increase, CET1 is noticeably reduced. Then the scale of buybacks or cancellations is reduced first. The reason credit loss is frightening for bank stocks is that it erodes return capacity more than it does profit and loss.

Let’s break this into two scenarios

The first is when CET1remains in the 13mid-range while buybacks are repeated. In that case, even if profits do not increase much, the per-share value keeps rising. PBR 1multiple becomes a range to accept more broadly.

The second is when rate cuts and credit losses overlap and CET1is when it clearly declines. In that case, even if the dividend is maintained, buybacks shrink first and the rerating logic stops.

In summary, you should look at these three things

First, the direction of CET1. This is a figure you should look at before net income.

Second, the size and frequency of buyback disclosures. Buybacks raise per-share value more decisively than dividends.

It is the cells, NIM, and credit costs. These two are the variables that are eating away at the fuel for a rebound.

Lastly

If you look at bank stocks only as dividend stocks, you are seeing only half of this story. The consensus target price is forming in the 19thousand 2won range, but more important than that number is how the company uses the money it earns. That is why we wrote the card-news conclusion as "capital allocation."
