What Ingra does

Ingra d.d. is a Croatian publicly listed joint-stock company (Zagreb Stock Exchange: INGR) that provides integrated engineering, construction, and energy-infrastructure services. Founded in 1955 as an export association of industrial manufacturers from former Yugoslavia and fully privatized since 1995, the company operates across three primary divisions: Engineering (civil infrastructure, residential, tourism, healthcare and transportation facilities), Energy (hydroelectric, thermal, wind and solar power plants plus industrial facilities), and Reconstruction (facade renovations, structural rehabilitation, and consortium participation in commissioning). It also runs a Scientific Research arm that collaborates with the University of Zagreb on urban planning, grid integration, and hydrogen technology.

The company's business model is project-based professional services revenue generated through direct competitive bidding on public infrastructure tenders and consortium arrangements with international partners. Customers are overwhelmingly government and public-sector entities across 30+ countries, including the Croatian Government, City of Zagreb, and governments of Algeria, Iraq, Kosovo, Libya, Sudan, Niger, and Nigeria. Contract sizes range from facade renovations to landmark projects such as Arena Zagreb (over €115 million in total construction cost). Pricing is not publicly disclosed; contracts are won through competitive tendering or private negotiation.

Ingra completed 800 capital investment projects over its operating history — including 83 hydroelectric power plants, 11 power plants, 11 hotels, 9 hospitals, 5 seaports, 742 km of highways, and 100,000 m² of residential buildings. The company currently employs 51–100 people, operates from its Zagreb headquarters, and is actively pursuing post-restructuring growth via renewable-energy project development, including the first Croatian solar hydrogen power plant in Ivanić Grad. Ingra successfully exited pre-bankruptcy proceedings in September 2023 after completing operational restructuring in December 2021. Its sole disclosed subsidiary is LANIŠTE d.o.o., which holds the Arena Zagreb investment.
