TFE (425420) 🔎 In-depth
KOSDAQ · Price as of 2026-08-06 · Updated 2026-08-09
TFE makes consumable back-end components used in the test step that screens finished semiconductors for proper operation, including test sockets, burn-in boards and COK parts. Because these parts must be replaced whenever a chip type changes, demand rises alongside chip production volumes. In 2025 the company earned revenue of ₩111.7 billion and operating profit of ₩19.1 billion (up 334% year over year) as earnings jumped sharply, and that momentum carried into the first quarter of 2026. It is building a ₩14.3 billion new plant in Hwaseong, funded through zero-coupon exchangeable bonds that carry no interest burden. What stands out lately is that if back-end semiconductor demand persists and the new plant translates into revenue, its low valuation relative to peers becomes a strength; on the other hand, because earnings dipped once in 2024, the durability of quarterly growth and the share dilution tied to exchangeable bonds and treasury-share disposal are points to watch together.

Core valuation metric
This stock's effective sub-sector is “Semiconductor Components” (Semiconductors & IT Components), a type typically read first through forward P/E.
Semiconductor components track the ups and downs of the chip cycle and end-device demand, so earnings can change materially from here. Since the profit still to come drives the price more than past profit, forward P/E, based on expected earnings, is the first lens.
Price against earnings alone becomes unstable when earnings swing. Reading it together with price against assets helps gauge the downside.
This note explains how each sector is typically valued and is educational context only, not investment advice.

🔎 In-depth analysis Reading
TFE makes components for the test step that screens finished semiconductors to check whether they "work properly." Its core products are test sockets that connect a chip to test equipment to exchange electrical signals, burn-in boards used in high-temperature reliability testing to weed out defects, test boards, and COK, a key replacement part for test equipment. The company is expanding its products beyond memory into non-memory (logic) testing, and because these parts are consumables that must be bought anew each time a chip type changes, demand rises as semiconductor production grows. In other words, TFE is not a company that sells chips directly but a back-end component supplier that earns money by supplying parts used repeatedly to test chips.
The latest close is ₩31,400 and the market capitalization is ₩387.7 billion. The price sits below its 20-day moving average (₩33,648) and below its 60-day moving average (₩44,518). It is under both its short- and medium-term moving averages, so the trend looks subdued. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 42.3, a neutral level. The one-month change is -16.9%, the three-month change is -57.8%, and the position relative to the 52-week high is -57.8%. Relative strength versus the KOSDAQ is 66 (on a 1-99 scale, converted from returns against the index over the past year with more weight on recent performance; higher means stronger than the market). It is stronger than roughly 66% of all stocks. Over the past three months it lagged the index by 29.4%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.
On a confirmed annual (2025) basis, the P/E ratio (how many times one year's earnings the price represents) is 21.41x and the P/B (how many times net assets the price represents) is 3.13x. However, this P/E is calculated on trailing earnings (a year already past), and since this company saw earnings fall sharply once in 2024 before jumping again in 2025, it is an earnings-inflection stock for which a single past year's figure is hard to use to judge cheap versus expensive. The real picture is closer to the forward estimate reflecting this year's expected earnings. On this year's expected earnings, the forward P/B is 4.08x, clearly lower than fellow semiconductor test-part makers (Leeno Industrial 42x, ISC 69x, TSE 65x). A high-growth company sitting at such a low forward P/E relative to peers can be read as a relatively undervalued signal rather than a burden. Profitability is sound, with ROE (how much is earned in a year on one's own money) at 16.6% and an operating margin at 17.1%, and the balance sheet is solid. Per the official 2025 year-end disclosure, total liabilities were ₩34.4 billion and total equity ₩109.2 billion, for a debt ratio (debt versus equity) of about 31.5% and a current ratio (assets soon to be converted to cash versus debt soon due) of 341%, so the debt burden is on the light side.
Over five years, revenue moved from ₩72.0 billion in 2021 to ₩63.7 billion in 2022, ₩80.3 billion in 2023 and ₩73.6 billion in 2024 before jumping to ₩111.7 billion in 2025 (up 51.8% year over year). Operating profit recovered sharply from ₩4.4 billion in 2024 to ₩19.1 billion in 2025 (up 334.0%), and net profit from ₩1.5 billion to ₩18.1 billion. The company stated directly in its DART filing that this rebound stemmed from "an improvement in the semiconductor business cycle." This growth is not a one-off flash: in the most recent quarter (Q1 2026) it continued, with revenue of ₩32.3 billion (up 46.8%), operating profit of ₩3.3 billion (up 12.0%) and net profit of ₩3.4 billion (up 31.3%). The reason this year's expected earnings run this high is clear: test parts are consumables that must be bought anew whenever a chip type changes, so demand grows as memory and non-memory production recovers and rises, and Q1 revenue already climbed nearly 47% year over year, showing that trend in actual numbers. On top of that, the company is expanding capacity with a new plant in Banwol-dong, Hwaseong, so if demand holds, the added capacity can flow through to revenue. The forward P/E on this year's expected earnings forming below peers reflects exactly this earnings-growth expectation.
Looking at the disclosure flow on a fact basis, first, the February 9, 2026 disclosure of a change in the profit-and-loss structure confirmed 2025 revenue of ₩111.7 billion and operating profit of ₩19.1 billion (up 334% year over year), verifying the sharp earnings rebound in numbers. As the next stage of growth, a new-facility investment to build a ₩14.3 billion plant in Banwol-dong, Hwaseong is under way (targeted completion June 16, 2026), and to fund it the company in January issued ₩10.5 billion of zero-coupon exchangeable bonds backed by treasury shares. In other words, it arranged the expansion funds without an interest burden. In February it paid part of its treasury shares as employee bonuses, and in May it held several IR sessions alongside the quarterly report to explain its results and business status directly. No dividend was paid in 2025 either.
This is a stock with clear strengths. Its business in consumable semiconductor-test parts benefits directly from rising chip production, its 2025 revenue and earnings actually jumped sharply, and that momentum continued into Q1 2026. On a solid balance sheet with a light debt burden, it is expanding capacity via a new plant, and the fact that a single company supplies the entire range of test parts is a differentiator. Points to keep an eye on together are that, since earnings dipped once in 2024 before recovering, the continuation of quarterly growth needs confirming, and that if the shares outstanding rise from exchangeable-bond conversion and treasury-share disposal, per-share value could be somewhat diluted. In sum, if back-end semiconductor demand persists and the new plant translates into revenue, its low valuation relative to peers can stand out as a strength; conversely, if quarterly growth cools or the cycle slows again, it could lose the momentum that expectation implies.
🔎 Valuation vs peers Fairly valued
Compared directly against makers of test parts with the same business substance, such as semiconductor test sockets and burn-in boards.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Leeno Industrial | 33.55x | 7.17x | 22.93% |
| ISC | 51.47x | 5.33x | 12.89% |
| TSE | 59.89x | 5.38x | 17.95% |
| Micro Contact Solution | 11.86x | 2.33x | 20.81% |
(a) Among fellow test-part makers, TFE's P/E of 28.4x and P/B of 4.71x are lower than Leeno Industrial, ISC and TSE (P/E of 42-69x) but higher than the smaller Micro Contact Solution (P/E of 11x), placing it in the middle of the peer set. (b) Relative to the large front-runners there is a discount, which can be seen as reflecting its still-small market cap (₩514.3 billion) and results track record; conversely, its top-of-peer revenue growth rate and upper-mid ROE are factors that narrow the discount. (c) The current P/E is a trailing value calculated on last year's confirmed earnings, which is a limitation for this company given its 2024 earnings plunge followed by a 2025 rebound, and the forward P/E on a seasonality approximation is somewhat lower than trailing. All told, it sits in the middle of the peer set as "neither cheap nor expensive," so we view it as within a fair range.

📖 Plain-language glossary — expand if you are new to this
- P/E
- How many times a year's net profit the price is worth (lower is cheaper relative to earnings). The P/E here is on trailing (last full-year) results; for companies whose earnings swing fast (memory chips and other cyclicals/high-growth), a forward P/E on this year's expected earnings is more accurate.
- P/B
- Price relative to net assets (equity). Around 1x means it trades near book value; below 1x means below book.
- P/S
- Price relative to a year's revenue — useful for growth companies with thin earnings.
- Net debt / EV
- Net debt = interest-bearing debt − cash. Negative means more cash than debt (net cash). EV (enterprise value) = market cap + net debt, closer to what it would cost to buy the whole business.
- EV/EBIT · EV/EBITDA · EV/Sales
- Enterprise value against operating profit (EBIT), EBITDA, or revenue. Unlike P/E these reflect debt and cash; lower is cheaper relative to earnings power or sales.
- FCF / FCF yield
- Free cash flow = operating cash − capex, the cash actually left over. FCF yield = FCF ÷ market cap; higher means more cash generated per unit of market value.
- Intrinsic value (DCF)
- Future free cash flow (or, for some capex-heavy but profitable names, forecast earnings) discounted to today to estimate per-share value. Because it shifts a lot with the discount-rate and growth assumptions, it is shown as a bear/base/bull range, and the basis and assumptions are disclosed in one line beneath it.
- ROE
- How much profit the company earns in a year on its equity (%). Higher means better returns on capital.
- EPS / BPS
- Earnings per share / net assets (book value) per share.
- Operating / net margin
- Profit left from the core business / final profit after tax and interest, per unit of revenue.
- Debt ratio
- Debt relative to equity (%). Higher means more reliance on borrowing (norms vary by sector).
- Current ratio
- Assets convertible to cash within a year against debt due within a year. Above 100% leaves some short-term headroom.
- Interest coverage
- How many times operating profit covers the interest owed. Below 1x means operating profit alone struggles to cover interest.
- Dividend yield / payout ratio
- The year's dividend as a % of today's price / the share of earnings paid out as dividends.
- Revenue CAGR
- Multi-year growth expressed as a single yearly average (compound annual growth rate).
- RSI (short-term signal)
- Whether recent price action is overheated or beaten down. Above 70 is overbought, below 30 oversold.
- MA20 / MA60 (moving averages)
- The 20- and 60-day average price. Price above them signals a firmer short-term trend.
- vs 52-week high
- How far below the past year's peak the price sits now (%).
