What JSW KOKS does

JSW KOKS S.A. is a Polish industrial manufacturer of metallurgical coke and coal-derived products, operating as a publicly listed joint-stock company (Warsaw Stock Exchange ticker: JKC) and a wholly-owned subsidiary of Jastrzębska Spółka Węglowa S.A. (JSW S.A.) within the JSW Capital Group. The company runs three coking plants—Koksownia Przyjaźń in Dąbrowa Górnicza (established 1987, the largest and most modern in Europe), Koksownia Radlin (operating for over 110 years), and Koksownia Jadwiga in Zabrze-Biskupice—producing over 3 million tonnes of coke annually for European and global steel industry customers. The registered share capital is 994,055,470 PLN, with the corporate headcount of 93 employees reflecting the standalone legal entity layer above the operational workforce.

The company's technology centers on coal carbonization at temperatures exceeding 1000°C in coking oven batteries, with a pioneering dry coke cooling (CDQ) installation at Koksownia Przyjaźń that recovers heat to generate approximately 110 MWe of electricity. The newly commissioned Battery No. 4 (ceremonially lit May 12, 2025) is among the most modern coke oven batteries in Europe, while the new EC Radlin cogeneration block (32 MWe electricity / 37 MWt heat, synchronized with the national power grid February 2026) converts excess coke oven gas into electricity and district heating for the Radlin municipality. By-products of carbonization—coke oven tar, raw benzene (containing aromatic hydrocarbons), sulfur (recovered via the Claus process), and ammonium sulfate—are sold to chemical industry customers, while processed coke oven gas and heat are distributed under regulated concessions.

Commercially, JSW KOKS sells its products through B2B direct sales channels, with the JSW S.A. Trading Office in Jastrzębie-Zdrój handling commercial operations. Revenue streams include one-time coke and carbon derivative sales, plus recurring revenue from heat distribution, electricity sales, and gas distribution under multi-year concessions. The company maintains certifications including ISO 9001 (since 1996), ISO 50001 (since 2011), and ISO/IEC 27001:2022, and has secured substantial public co-financing from Polish environmental funds (NFOŚiGW, WFOŚiGW) and EU structural funds for its modernization projects. Customer concentration is heavily skewed toward the European steel/metallurgy sector, with secondary exposure to the chemical industry and district heating/energy customers.

Broad incumbents

• ThyssenKrupp Steel Europe: ThyssenKrupp Steel Europe operates integrated steel production in Germany including coke-making facilities, making it a major European customer/producer of metallurgical coke. It is comparable in terms of blast furnace route, integrated value chain, and European regulatory exposure, though it captures value downstream in steel rather than specializing in coke.
• ArcelorMittal Poland: ArcelorMittal Poland operates integrated steelmaking facilities in Poland, including Koksownia Zdzieszowice, a metallurgical coke plant. It is both a potential customer and a competing coke producer in the Polish market, and represents a broader incumbent that captures value across the steelmaking value chain rather than specializing in coke.
• POSCO: POSCO is a Korean integrated steel producer with substantial in-house coke operations, historically one of the largest coke consumers globally. It is comparable in terms of integrated blast furnace operations and coke-making technology, though it is a vertically integrated incumbent that captures value primarily downstream rather than as a pure coke specialist.
• Nippon Steel Corporation: Nippon Steel operates integrated steelmaking in Japan with significant internal coke battery operations, making it a major global coke producer. It is comparable as a large integrated player with metallurgical coke production, though it operates at much larger scale and serves primarily Asian markets rather than competing directly in Europe.
• Tata Steel Europe: Tata Steel Europe operates integrated steelmaking in the UK and Netherlands with internal coke production. It is comparable as a European integrated steel customer/producer with metallurgical coke needs similar to those JSW KOKS serves, though it is broader in scope (downstream steel) and currently undergoing significant restructuring (e.g., Port Talbot transition).

Regional players

• Severstal: Severstal is a Russian integrated steel producer with own coke-making operations supporting its blast furnace route. It is comparable in terms of integrated coke production for steelmaking but operates primarily in Russian and CIS markets with limited direct competition with JSW KOKS in the European Union.
• METALINVEST: METALINVEST is a Russian/Ukrainian integrated steel and mining group that operates metallurgical coke production as part of its vertically integrated value chain. It is comparable in terms of integrated coke production serving blast furnace steel, but operates primarily in Eastern European/CIS markets rather than competing directly in JSW KOKS's core European customer base.

Others

• ThyssenKrupp Uhde: ThyssenKrupp Uhde is a leading engineering and technology provider for coke oven plants and coking technology globally, including Polish installations. It is comparable as an adjacent ecosystem participant that supplies technology and engineering services to the metallurgical coke industry, including potentially JSW KOKS's own modernization programs.

Direct peers

• SunCoke Energy: SunCoke Energy is a US-listed pure-play metallurgical coke producer, serving blast furnace steel customers in North and South America. It is the closest publicly traded pure-play comparable to JSW KOKS in terms of product focus (metallurgical coke) and customer segment (integrated steel mills), though it operates at slightly larger capacity and in a different geographic market.
• Koksownia Częstochowa Nowa (ISD Group): Koksownia Częstochowa Nowa is a Polish metallurgical coke producer operated by ISD Group, directly competing with JSW KOKS in the Polish and European metallurgical coke market. It is the most direct geographic competitor and operates in the same Polish/European regulatory environment as JSW KOKS.
