Comparable business model mix of contractor + developer activities and similar exposure to Polish public and private infrastructure spending.

Competes with Instal Kraków on municipal water/wastewater and energy infrastructure tenders, and similarly diversifies into real estate development, making it the closest comparable Polish listed peer.
• Mostostal Zabrze S.A. Polish WSE-listed industrial and power-plant construction contractor. Highly comparable to Instal Kraków's energy-sector installation business, with similar exposure to flue gas desulfurization, boiler house and power infrastructure projects for Polish utilities.
