What Polimex Mostostal does

Polimex Mostostal S.A. is a Polish engineering and construction company established in 1945 and listed on the Warsaw Stock Exchange (ticker: PXM) since 1997. Operating as a general contractor in the EPC formula, the group delivers turnkey industrial investments in five segments: Industrial Construction, Oil/Gas/Chemicals, Power Sector and Service, Infrastructure, and Manufacturing. Its primary customers are large enterprises in the energy and petrochemical industries, including PGE GiEK (Bełchatów), ENEA Wytwarzanie, PKN Orlen, PERN, and technology partners such as Alstom, Andritz, and RAFAKO; additional clients include BASF and TOTAL in Belgium and municipal/government buyers.

The capital group executes work through eleven wholly-owned subsidiaries: Naftoremont-Naftobudowa (petrochemical/refinery services), Polimex Budownictwo (general industrial construction), Polimex Energetyka (power), Mostostal Siedlce (steel structures with 3,000 tons/month capacity, ~50% exported), Polimex Operator (equipment rental), Stalfa (steel/aluminum processing), Polimex Infrastruktura (roads/bridges), Polimex-Mostostal ZUT, Energomontaż-Północ Bełchatów (general contracting at Bełchatów), Instal-Lublin (HVAC/heat/sanitary installations), and Czerwonogradzki Zakład Konstrukcji Stalowych. Certifications include ISO 9001:2015, ISO 14001:2015, PN-ISO 45001:2018, and UDT permits for regulated industrial equipment. Ownership is concentrated: ENEA (15.86%), PGE (15.92%), Orlen Technologie (15.85%), and Energa (15.85%) jointly hold 63.48% of voting rights.

Revenue is generated primarily through project-based EPC contracts secured via public procurement (zakupy.polimex.pl) and direct enterprise negotiation, supplemented by steel-structure manufacturing/hot-dip galvanizing exports and specialized industrial repair services. The 2025 financial year showed operating revenue of PLN 4,130 million (+45% YoY), EBITDA of PLN 243 million (versus PLN -351 million in 2024), and net profit of PLN 134 million at a 3.3% margin. Go-to-market is sales-led, driven by industrial tendering, multi-language corporate communications (PL/EN/DE/RU), and participation in industry events such as the Ukraine Recovery Conference. Strategic positioning has expanded in 2026 toward Ukraine reconstruction and small modular reactor deployment via partnerships with Budimex, AMW Sinevia, SGE and ATEC Group.
