0. Bottom line first

4Q25 operating profit of KRW 1.5 billion was a clear shock, missing the KRW 48.3 billion consensus by 96.9%. But the source argues that after removing roughly KRW 50 billion of turnaround and year-end one-off costs, adjusted operating profit would be about KRW 51.5 billion, making the quarter look more like a big bath that lowers the burden for 2026.

4Q25

KRW 1.5B OP

Down 98.2% QoQ and 96.9% below consensus.

One-offs

~KRW 50B

Maintenance, bonuses/provisions, and negative raw-material lag were concentrated in the quarter.

1Q26 view

KRW 84.9B

The source forecasts a 5,378% QoQ rebound in operating profit.

Official fact: Kumho Petrochemical announced 4Q25 consolidated revenue of KRW 1,589.7 billion, operating profit of KRW 1.5 billion, and net income of KRW 2.7 billion through its January 29, 2026 DART filing. The filing is here: DART January 29, 2026 filing.

Interpretation: The headline numbers look like fundamental damage, but if the issue is cost timing, they can also create a lower base for 2026. The key confirmation point is the speed of 1Q26 normalization.

1. Reference material and framework

The source first lists Yoon Jae-sung's Telegram https://t.me/energy_youn, a 4Q25 preview material https://vo.la/naiskZQ, and the DART filing https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260129800356. I read the post by separating fourth-quarter cost quality, first-quarter normalization, and structural 2026 drivers.

Operating profit fell 98.2% QoQ and pre-tax profit turned to a KRW 9.8 billion loss. The source breaks the drivers into turnaround maintenance, year-end bonuses/provisions, and negative raw-material lag from oil and naphtha price volatility.

3. Segment read: EPDM holds, NB Latex remains the swing factor

Synthetic rubberKRW 15.8B OP, 2.6% OPMStayed profitable despite one-off costs; SSBR and NdBR for tires helped.
NB LatexLow-60% utilizationHigh BD cost and low utilization hurt, but 2026 utilization is the leverage point.

Synthetic resinKRW 266.2B revenue, KRW 9.5B operating lossABS demand weakness plus maintenance costs caused a loss.
Phenol derivativesKRW 22.3B operating lossBPA maintenance and weak epoxy-related demand; potential bottoming process.

Interpretation: This was not a quarter where everything broke. EPDM still produced double-digit OPM, and synthetic rubber stayed profitable. The issue is how fast NB Latex, phenol, and resin utilization recover.

4. 1Q26 rebound mechanism

The source forecasts 1Q26 operating profit of KRW 84.9 billion and controlling-shareholder net income of KRW 106.8 billion. The 5,378% QoQ OP increase assumes a low base, removal of one-offs, and positive raw-material lag.

  • About KRW 50 billion of fourth-quarter maintenance and one-off costs disappears.
  • The average December 2025 butadiene price was in the mid-USD 800 per ton range, while the 1Q26 market price is around USD 1,250 per ton.
  • Low-cost feedstock flowing into production while selling prices rise can improve synthetic-rubber spreads.
  • Rising feedstock prices can trigger tire-customer restocking and improve price pass-through.
  • Kumho Mitsui Chemicals' MDI price increase and removal of 4Q costs can lift net income.

5. 2026 Triple Crown

Structural 2026 DriversMDI, synthetic rubber, and shareholder returns
LNG and MDICore input for R-PUF insulation
BD and rubberNCC restructuring and supply shortage
NB Latex and SSBRGlove normalization and EV tires
Returns40% return ratio, treasury cancellation
The re-rating case is a move from commodity chemical to energy-infrastructure and high-function material exposure.

MDI is essential for LNG carrier insulation. LNG must be kept at minus 163 degrees Celsius, and membrane LNG carriers use reinforced polyurethane foam, or R-PUF, where MDI is a key curing agent. The source describes Kumho Mitsui Chemicals as Korea's only MDI producer.

Kumho Mitsui completed a 2024 expansion from 410,000 tons to 610,000 tons per year, and plans to invest KRW 140 billion in 2026-2027 to debottleneck capacity to 710,000 tons by 2027. The source expects the additional expansion alone to add about KRW 250 billion in annual sales, and equity-method income for Kumho Petrochemical to rise from KRW 93.4 billion in 2024 to KRW 180.0 billion in 2026.

6. Synthetic rubber, NB Latex, and SSBR

As Asian and European NCC operating rates fall because of China-driven ethylene oversupply, C4 fractions and butadiene output decline. The source argues that this BD shortage can support synthetic-rubber price pass-through and wider spreads.

NB Latex is described as recovering after 2023-2024 destocking. Medical glove demand is growing more than 7% annually, and major glove-maker utilization recovered to about 70% by late 2025. Kumho Petrochemical secured 950,000 tons per year of NB Latex capacity through 2024 expansion and expects utilization around 65% in 2026, according to the source.

EV tires require better abrasion resistance and grip because EVs are heavier and deliver higher initial torque. SSBR expansion is therefore a high-value mix improvement that can reduce commodity-rubber volatility.

7. Balance sheet, shareholder returns, and risks

The source expects Kumho Petrochemical to shift to a net-cash position in 2026. The company targets a 40% total shareholder return ratio for 2024-2026, paying 20-25% of separate net income as cash dividends and using the rest for treasury share purchases and cancellation. The post also notes a KRW 50 billion treasury cancellation plan for 2025 and a plan to cancel all treasury shares held over three years, about 2.62 million shares.

Risks

  • U.S. and China slowdown could weaken auto and appliance demand.
  • If butadiene rises on supply issues without demand support, pass-through may fail and margins can compress.
  • Middle East and Russia-Ukraine geopolitical risks can increase oil and naphtha volatility.

8. 2026 outlook and my view

Metric2026 estimateYoY
RevenueKRW 7,091.9B+2.6%
Operating profitKRW 447.8B+64.8%
Controlling net incomeKRW 516.7B+76.8%
EPSKRW 17,783+79.8%

The source cites an average broker target price of about KRW 170,000-180,000, implying 20-25% upside from its reference point. The source uses a BUY framing; I would verify the thesis through 1Q26 normalization, MDI equity-method income, NB Latex utilization recovery, and actual treasury-share cancellation execution.
