According to Bosnian media outlet Klix.ba, the Czech Republic imported more than 30,000 artillery shells from Pretis. Though Pretis is majority-owned by the Bosnian state, US arms firm Regulus Global, which has procured arms and ammunition for Ukraine and previously Syria, holds a 41.5 per cent stake through an offshore company and recently proposed a $100 million upgrade of the company.

Regulus also owns 25.7 per cent of shares in another Bosnian arms manufacturer called Binas d.d, with Regulus CEO Joe Wallis telling Al Jazeera Balkans in July: “We see the chance to build something that serves both the European defence needs and also helps economic growth in Bosnia and Herzegovina.”

With Russia’s war in Ukraine, Wallis said artillery “is back in the centre” of modern warfare.

Regulus says it has delivered “more than 100,000” 155mm artillery shells to Ukraine, though it is embroiled in a court dispute in London over a $1.7 billion contract to sell such shells to the Ukrainian government, the FT reported in May.
