It does appear to be the case that they (Trek) did so.
Now, the question is; have they not actually signed him, or have they signed him, but forgot that they're not actually allowed to announce it yet?
At least I assume that they're not allowed to announce it... it's before August 1st next year.
Ayuso's contract with UAE was announced in April 2020, so I assume Trek will be allowed to announce this deal long in advance as well, provided AWP actually signs with them.
