The story

Founding and J&P era (1986–2018)

The Avax Group traces its origins back to 1941, with the establishment of J&P Overseas. In 1986, Avax S.A. was founded, while in 1993, J&P Hellas began operating in Greece. Avax S.A. has been listed on the Athens Stock Exchange, since 1994. In 2002, Avax merged with J&P Hellas to form J&P Avax.

2018 - AVAX S.A. announced the completion of the absorption of its 100% subsidiary ATHENA S.A.

In 2017, J&P Avax was fined €18.3 million ($20.67 million) for colluding with other major Greek construction companies for 23 years (1989–2012) to rig the tenders for public work projects in their favour, including projects that received funding from the European Union.

Post-J&P era (2018–present)

Avax Group's then-parent company J&P Overseas (Joannou & Paraskevaides) collapsed and entered liquidation on 24 October 2018, with a deficit of around $750 million (€635.06 million) and a lot of unpaid wages. Writing for Forbes shortly after its collapse, Antonis Antoniou observed that J&P Overseas suffered from a feud between the Joannou and Paraskevaides families after its founders died, resulting in mismanagement: shortly before collapse, J&P Overseas sold off its stake in Queen Alia International Airport in Amman, which according to the Financial Mirror in 2018 was expected to earn J&P at least $100 million (€84.67 million).

On 27 March 2019, J&P Avax returned to its original name (Avax) to distance itself from its bankrupt parent, while also approving a €20 million ($22.39 million) fundraising effort to increase its liquidity. On 10 December 2019, Avax announced that they bought J&P Energy & Industrial Projects, a former subsidiary of J&P Overseas.
