Perez has not achieved a podium finish since April at the Chinese Grand Prix, and has gained just 13 points in his last seven events.
This dismal run of form has hampered Red Bull's chances of claiming a third successive constructors' championship title, and they sit 53 points behind leaders McLaren with just two races remaining.
Perez's Red Bull future
Due to his poor performances, Perez's position in the team has been constantly questioned throughout 2024, despite seemingly retaining the support of Red Bull team principal Christian Horner.
Liam Lawson was promoted into the VCARB seat back in September, and Marko suggested that he and Yuki Tsunoda were involved in a shootout for the seat alongside Verstappen for 2025.
Now, Marko has suggested that there is a deadline for when their final decision around Perez's future will be made.
"There will be a meeting after Abu Dhabi and the result of this meeting will be presented to the shareholders and they will then decide what the driver situation for both teams will look like for next year," team advisor Marko told Austrian broadcaster ORF in Las Vegas.
"I don’t know the exact gap now, but I think Checo has over 200 points less than Max. And then it’s clear that the Constructors’ title is no longer possible.
"So if Sergio was anywhere near (Lewis) Hamilton and (George) Russell or Ferrari or even McLaren, then we would be well ahead again."
