Fair Value models

Bear 6,846 KRW Fair Value 9,128 KRW Bull 10,660 KRW
Price 3,575 KRW · Upside +155.3%
Capped: our models arrive at a very high value here. We deliberately show a more cautious Fair Value.
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (746.31 KRW per share) are deliberately not added. Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds. Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Revenue & earnings trend

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card. 54/100
The company is growing, but growth may require heavy reinvestment or weak cash conversion.
Revenue growth 1 year
+8.3%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

Revenue growth 13 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+4.6%
What shareholders gained per year (last 5 years), in KRW ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate. Measured in KRW: this currency has depreciated against the euro and dollar over the long run, so part of the nominal rate is currency erosion that never reaches a EUR/USD investor.

Earnings per share, growth per year+18.4%

Pace: 5 vs 10 years ⓘTwo data points, not a trend model: earnings growth per share over the last 5 fiscal years against the last 10.

What is the P/E ratio of 013870?
Gmb Korea trades at a price-to-earnings ratio of 3.2 (as of Nov 9, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of 9,128 KRW is built from several models across several years. Median P/E at fiscal year-end, 9 fiscal years (2016 to 2025), reported earnings: 7.9. Other multiples: P/B 0.2, P/S 0.1, EV/EBITDA 0.9.

Which stocks are comparable to Gmb Korea?
From the same area (Consumer Cyclical) we also value O'Reilly Automotive, Inc, AutoZone, Inc, Hyundai Mobis Co, Fuyao Glass Industry Group, among others. Each of them has its own fair-value calculation on this site using the same models, so the comparison is like for like.
Is Gmb Korea stock attractive at the current price?

Is it still worth investing in stocks now?
The global stock market currently sits 13.3% above its aggregate fair value. Gmb Korea currently trades 61% below its own fair value, and the market average says nothing about that. An expensive market is no reason to stay out and no reason to buy everything at once: keep a broad savings plan running, buy single stocks only with money you can do without, and hold part of your money liquid while the market is high. The full picture including sectors is on is it worth investing now.
What is the share price of Gmb Korea (013870)?
The closing price on Nov 6, 2026 was 3,575 KRW. Our model-based fair value is 9,128 KRW, about +155% upside (undervalued). We carry closing prices from our data provider, not a live tick.
What should I pay attention to with Gmb Korea right now?
The large discount to fair value meets weak quality (46/100). That raises the risk this is a value trap rather than a bargain. The price is below even our cautious bear case (6,846 KRW). The market is more pessimistic than our downside scenario. The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
