Samji Electronics: Sharp Profit Jump and Low Multiples, With a Pullback From the 52-Week High

Thesis

The data supports a business whose earnings have stepped up sharply: trailing operating income of ₩600.9B compares with ₩162.4B for full-year 2025, and operating margin rose to 8.7% from 3.8%. Trailing ROE of 44.4% is well above the 9.6% to 16.9% range of 2021-2025. Multiples are low against both peers and the company's own year-end history.

What the data does not settle is whether the jump is durable. Trailing net margin is only 3.5%, free cash flow is negative at ₩450.9B, and no news headlines are available to explain the change. The share price is 57.5% below its 52-week high of ₩64,500 but well above the low of ₩11,360, so sentiment has swung widely.

Business overview

Samji Electronics is a KOSDAQ-listed company in the electronics sector, founded in 1981 and listed in 1999. It has two representative directors, Park Doo-jin and Lee Tae-hoon, and 16,318,522 listed shares. Market capitalization is about ₩447.1B at a close of ₩27,400 on 2026-10-19.

Revenue grew from ₩2.5T in 2021 to ₩4.3T in 2025, with a dip of 13.5% in 2023. Trailing revenue to H1 2026 is ₩6.9T. The data does not describe products or segments.

Financial analysis

These figures come from filed financial statements. Revenue rose 33.0% in 2024 and 27.7% in 2025 to ₩4.3T. Operating income was ₩162.4B in 2025 and net income ₩75.7B. Operating margin sat between 3.0% and 3.8% from 2021 to 2025 before reaching 8.7% on a trailing basis.

Trailing net income is ₩242.4B, a 3.5% net margin. The gap between operating and net margin is notable and the data does not explain it. Liabilities to equity are 152.1%. Cash is ₩264.9B against borrowings of ₩36.9B. Free cash flow is negative ₩450.9B, which suggests heavy working capital or investment needs, though the cause is not given.

Valuation

The stock trades at a P/E of 1.8, P/B of 0.7 and P/S of 0.1, with a dividend yield of 2.0%. Year-end P/E ranged from 2.3 to 6.5 and P/B from 0.3 to 0.7 over 2021-2025, so the current P/E is below that range while P/B is at its upper end. Enterprise value is ₩219.1B; EV/EBITDA is not available.

Listed peers trade at higher multiples: Samsung Electronics P/E 8.5 and P/B 2.3, LG Electronics P/E 26.7 and P/B 1.0, Hanwha Vision P/E 17.5 and P/B 2.2, RFHIC P/E 41.7 and P/B 3.7, and KMW P/B 5.3 with no P/E. These companies are much larger and may differ in business mix.

The valuation model is a model estimate based on the assumptions shown: a 5-year discounted cash flow at a 7.6% rate on trailing figures to H1 2026. It gives ₩260,358 per share in the base case, ₩87,688 in the bear case and ₩559,226 in the bull case, against a share price of ₩27,400. The very wide range and the gap to the price show how sensitive the model is to its assumptions, especially whether the recent profit level persists. It is not a target.

Catalysts

• The half-year report filed on 2026-08-14 supplied the trailing figures showing operating income of ₩600.9B.
• A buyback trust contract was signed on 2026-07-06, and a status report on acquisitions under the trust was filed on 2026-10-12.
• Three 5%+ holding reports were filed between May and July 2026, showing changes in large shareholdings.
• Foreign investors were net buyers of about ₩2.4B over 20 days, though foreign ownership fell to 6.1% from 6.9% over 60 days.
• The next quarterly filing will show whether the higher margin continues.

Risks

• The earnings step-up may not persist, since margins were 3.0% to 3.8% for the five prior years.
• Free cash flow is negative ₩450.9B, which could strain liquidity if it continues.
• The share price has fallen 18.3% over three months and is volatile, with a 52-week range of ₩11,360 to ₩64,500.
• Liabilities to equity of 152.1% indicate meaningful leverage, even with low borrowings.
• The model's bear-to-bull range of ₩87,688 to ₩559,226 reflects high uncertainty, and no news is available to explain the profit change.

Closing view

The filings show a sharp improvement in profit and returns, and the stock trades at low multiples relative to peers and its own earnings. Against that, the improvement is recent, cash flow is negative, net margin is modest and the share price has pulled back from its peak. The evidence points to a company whose outlook depends on whether the new profit level holds, and the data given is not enough to resolve that question.
