SKC는 리튬이온 이차전지 소재인 전지박(Copper Foil) 등 제품을 생산, 판매하는 이차전지 소재사업, PO 등을 생산, 판매하는 화학사업, 반도체테스트용 실리콘러버소켓,테스트 장비 등을 판매하는 반도체 소재/부품 사업 등을 영위하고 있습니다.이차전지 소재사업의 전지박은 이차전지에서 음극집전체로 작용하는 핵심 소재로서 이차전지 산업과 밀접한 관련이 있으며, 전기차, ESS 및 기타 중소형 IT기기 산업에 적용되는 제품 입니다. 전지박 시장은 크게 사용 용도에 따라 IT기기 및 전동 공구 등에 적용되는 소형 전지 시장과 EV 및 ESS등에 적용되는 중대형 전지 시장으로 분류됩니다.화학사업부문은 프로필렌옥사이드(PO), 프로필렌글리콜(PG) 등을 생산하여 국내외 관련산업에 안정적으로 공급하고 있습니다. PO(Propylene Oxide)는 폴리우레탄의 원료인 PPG에 약 60% 가량이 소비되고 다음으로 PG(Propylene Glycol)가 전체 수요의 20%를 차지하며 나머지는 PGE(Propylene Glycol Ether), 계면활성제, 난연재 등의 제조에 사용됩니다. 국내 시장은 PO의 경우 수입에 의존하였으나, 1991년 SKC가 국내 최초로 생산설비를 갖추면서 내수 생산기반이 확보되었습니다.PG는 당사가 국내 최초로 상업화한 이후, 현재까지도 국내에서 유일하게 생산하고 있는 고부가 PG 제품입니다. 또한 다음과 같은 이유로 신규 경쟁자 진입이 용이하지 않습니다.- 세계 시장에서 PG의 기반 원료가 되는 PO 생산기술을 보유한 업체가 많지 않음- 신규 기술 개발도 PO 생산 업체 위주로 이루어져 과점 시장 형태- 대단위 투자비 필요반도체소재사업부분은 반도체 IC와 IT 디바이스등을 테스트하는 반도체테스트소켓 등을 생산, 판매하고 있습니다. 특히 반도체테스트용 실리콘러버 소켓은 세계 최초로 상용화, 양산화에 성공해 글로벌시장 약 90%를 점유하고 있습니다.회사의 종속기업인 SK엔펄스(주)는 2023년 2월 1일자로 SK텔레시스(주)를 흡수 합병하였습니다.반도체 후공정 핵심 소모품 사업 진입을 위하여 (주)ISC를 인수하였습니다(2023.10.04). 사업구조 재편을 위해 SK엔펄스(주)의 파인세라믹 사업부문을 매각하였습니다(2024.02.02). 그 외 성장사업 투자 확대를 위하여 SK피유코어(주)를 매각하였습니다(2024.02.29). 자산유동화를 위해 SK엔펄스(주)의 중국사업 관련 자회사 지분을 매각하였습니다(2024.09.12). 이에 대한 상세 내용은 2024.05.31 타법인 주식 및 출자증권 처분결정(자회사의 주요경영사항)

  • The summary is written separately from the filed text and is not the filer's wording, so it may phrase things differently from or omit parts of the original, which is shown alongside for checking.

VaR

5.15%
[3.22%, 8.50%] · As of 2026-10-02
VaR by window

The headline's measure for each of the three windows on one scale, the dot being the estimate and the bar its interval. The windows are nested and share their observations, so the three readings are not three independent measurements. The selected window is highlighted.

Daily return distribution

The issue's daily returns over the chosen window counted into equal-width bins. The vertical lines mark the VaR and cVaR above on the loss side. The published VaR sample applies exclusion rules for halts and first sessions that this raw daily series does not, so the bars and the marks can differ slightly at the edges.

Drawdown

Deepest drawdown 63.1% (2026-07-30). How far below its previous peak the issue stood each day over the chosen window, a description of the path already travelled.

A 252-day window rolled one day at a time over the longest daily span of the characteristic line. It shows when the beta against the KOSPI200 and the annualized volatility of the issue's excess return rose and fell, and unlike the headline figures above it carries no interval.

252-day rolling annualized volatility

Each point is one period's index excess return and issue excess return, and the line is the regression fitted to those points. The risk-free rate is the certificate of deposit rate.

Consolidated basis

Profit flowKRW 100M

This fiscal year shows a loss at gross profit, operating income, profit before tax or net income, so it is left to the table rather than drawn as a flow.

This diagram traces where revenue goes at each step on its way to net income, using the filed amounts as they are. The non-operating result is taken as the difference between profit before tax and operating income and is shown as income or expense by its sign, and whatever a step's items leave unexplained is shown separately as other.

Revenue compositionKRW 100M

Margins%

Cash flow by activityKRW 100M

Balance sheet compositionKRW 100M

Debt ratio%

The left bar splits assets into current and non-current and the right bar splits the financing of those assets into liabilities and equity, so the two bars stand at the same height.

Quarterly resultsKRW 100M

Year-on-year growth%

Each quarterly bar is that quarter's three months and is never mixed with an annual figure. The growth rate is computed only where the same quarter a year earlier is also shown here, and is left blank when the base was a loss.

Cash conversion cycledays

Free cash flow breakdownKRW 100M

Inventory days and receivable days stack upward, payable days hang downward, and the cash conversion cycle they net to is drawn as the line. Each day count uses the average balance with the prior year, so the oldest year is not drawn. A day count whose line was not filed is left out, and the cycle is shown only for years that carry all three.

Free cash flow is cash from operating activities less spending on property, plant and equipment, and all three bars keep the sign as filed.

Owners' net margin%

ROE%

ROE is the product of the owners' net margin, asset turnover and financial leverage. All three use period-end balances as denominators, and profit and equity are on the owners' basis, so the product matches the ROE in the table.

In the latest fiscal year operations consumed cash while investing and financing activities brought cash in.

A year whose own filing is absent is filled from the restated comparative in the following filing, and is marked as such. Operating indicators outside the statements, such as order backlogs, and audit opinions are not covered here, and per-share figures follow the filed values without retroactive adjustment for share splits.

The auditor's name and the opinion are transcribed verbatim from the filed audit report, and the wording follows the filer. A fiscal year shown twice means the filing carried two entries that the source does not distinguish.

Korean audit opinions come in four kinds, where an unqualified opinion (적정) finds the statements fairly presented, a qualified opinion (한정) does so except for a stated matter, an adverse opinion (부적정) finds them not fairly presented, and a disclaimer of opinion (의견거절) means the auditor could not obtain enough evidence to form a view.

Valuation

Valuation multiplesx

PER and PBR divide each period's closing price by the per-share figure filed for that same period, and a loss period is left blank. The quarterly view is a multiple of quarterly EPS.

Dividend historyKRW

The dividend-per-share bars are restated onto the current share basis for splits and par-value changes. The payout ratio and the dividend yield divide figures filed for the same period and are left unadjusted.

Payout ratio and dividend yield%

PER bandKRW

The price is the adjusted close and each band line multiplies the EPS of the latest completed fiscal year by a fixed multiple. The previous year's EPS stays in force until the next fiscal year ends, and the multiples divide the range between the lowest and highest annual PER on record into equal steps.

Discounted cash flow familyKRW

Each fiscal year's figures use that year's accounts and the treasury yield at its period end, with beta held at its current value, and splits or par changes are restated to the current share basis.

How the figures are calculated

Each model's formula is shown in symbols and then with this issue's own numbers substituted, step by step. Changing a value in the assumptions panel changes the numbers here too. Firm-level amounts are in hundred million won and per-share values in won.

Cost of equity

r=rf+β×ERPr = r_f + \beta \times \mathit{ERP}

r = 4.40% + 1.01 × 5.00% = 9.46%

Initial growth

g1=max⁡{ROE×(1−payout), 0},gt=g1+(gT−g1) t−1N−1g_1 = \max\{\mathit{ROE} \times (1 - \text{payout}),\,0\},\qquad g_t = g_1 + (g_T - g_1)\,\frac{t-1}{N-1}

g_1 = max(-88.26% × (1 − 0.00%), 0) = 0.00%

Growth starts at this value in the first year and falls by equal steps each year to reach the terminal rate in the fifth

Residual income model RIM

P0=B0+∑t=1NRIt(1+r)t+RIN(1+gT)(r−gT) (1+r)N,RIt=(ROE−r) Bt−1P_0 = B_0 + \sum_{t=1}^{N} \frac{\mathit{RI}_t}{(1+r)^t} + \frac{\mathit{RI}_N (1+g_T)}{(r - g_T)\,(1+r)^N},\qquad \mathit{RI}_t = (\mathit{ROE} - r)\,B_{t-1}

B_0 = 21,973 KRW, ROE = -88.26%, payout ratio = 0.00%, r = 9.46%, g_T = 2.00%

P_0 = 21,973 + -21,972 + -35 = -35 KRW

The cost of equity is the risk-free rate plus beta times the equity risk premium. Initial growth is the newest fiscal year's return on equity times its retention ratio, floored at zero, and falls by equal steps from that value in the first year to the terminal rate in the fifth. Only the Gordon model grows at the terminal rate from the start. Discounted cash flow starts from operating cash flow less capital expenditure, where FCFF adds after-tax interest paid and discounts at the weighted average cost of capital, and FCFE adds net borrowing and discounts at the cost of equity. The residual income model adds to book value per share the present value of earnings above the equity charge.
