The Virtuosi outfit has run the Russian Time squad successfully for four years, with many staff remaining from its previous iteration, iSport.
Virtuosi-run Russian Time won the teams' championship in 2017 with Artem Markelov and Luca Ghiotto, and have won races with Markelov and Tadasuke Makino in 2018.
But as reported by Motorsport.com last month, the Russian Time team has handed over its cars, equipment and entry to UNI-Virtuosi.
UNI-Virtuosi team owner Andy Roche said: "We are pleased to announce that UNI-Virtuosi will race in Formula 2 next season.
"We have enjoyed a very successful four years with Russian Time and would like to wish Artem [Markelov] and Svetlana [Strelnikova, RT team principal] good luck with their future plans.
"UNI-Virtuosi Racing's owners, Paul Devlin, Declan Lohan and I are fully committed to continue with the same mind set which led Russian Time to the 2017 Teams' championship, 13 race wins and 38 podiums and the team will continue with the same engineering staff and structure to ensure this success continues in to 2019 and beyond.
"We are close to announcing drivers for 2019 and expect to a final decision very soon."
In the F2 post-season test last week in Abu Dhabi, Ghiotto and European Formula 3 frontrunner Guan Yu Zhou tested for the team, but no drivers have been announced in the new squad for 2019.
Motorsport.com understands at least one driver will be announced on Wednesday.
