As confirmed by the latest editorial in Milannews.it, this week there will be a meeting to finalise the renewal of Matteo Gabbia's contract.

The defender has earned this extension, embodying the true Milan spirit, much like Davide Calabria.
Gabbia has shown that with time, dedication, and the desire to grow, the results come, and he has achieved significant success, becoming a key player in Milan's defence.
Besides Matteo Gabbia, there's Davide Calabria's contractual situation...
Speaking of Calabria, though, the source reports that he has never demanded a 4 million euros salary; he simply wants to discuss a renewal based on his current contract. Yet, from Casa Milan, there's been silence.
This isn't a great way to treat one of your own, especially considering they invested 15 million euros in Emerson Royal, not exactly a phenomenon that justifies discarding a reliable player so easily. And 2 million euros for a backup at a top club is the standard, not the exception.
