Yes, take a look at this video. Here, John, AKA PokeMen talks about the future, SPOILERS, move tutor moves in USUM. He links this list, which shows us the different moves each Pokémon can learn through these tutors. In it, they show us the new UBs, Mythical, and Adhesive's evolution's stats and moves.
To answer your question, Adhesive's evolution is real and evolves "after Dragon Pulse is learned".
You will receive a level 40 Poipole from the Ultra Recon Squad after defeating Ultra Necrozma and, to evolve it, go to the Move Relearner on Mount Lanakila to teach it Dragon Pulse.
