No. If you look at the 2020 annual report (page 89) they show 100% equity interest in Italy and in Romania.

In Italy they have given an economic participation away, not necessarily an equity interest. This is what AR says (page 72):
As previously announced ADX completed a farmout with SDP Services Limited (“SDP”) where SDP can earn an interest of 50% interest in the d363 C.R-.AX Permit (License) containing the Nilde Oil Redevelopment Project by funding the work program commitments of Audax Energy Srl (Audax) a wholly owned subsidiary of ADX up to a maximum of EUR 20.82 million. The transaction is conditional upon the Italian Licensing Authorities ratifying the License. Upon ratification of the License SDP will receive 5% net profits royalty interest attributable to any future production from the Nilde Field. ADX will remain operator of the license.

In Romania they have given equity away, (to Reabold), so not quite sure of how they still put 100%, but they add the following note to the entry:

Note 2: ADX holds a 49.2% shareholding in Danube Petroleum Limited (Danube). The remaining shareholding in Danube is held by Reabold Resources Plc. Danube via ADX Energy Panonia Srl holds a 100% interest in the Parta Exploration license (including a 100% interest in the Parta Appraisal Sole Risk Project) and a 100% interest in the Iecea Mare Production license. ADX is the operator of the permit pursuant to a Services Agreement with Danube.
