Red Bull said they were "surprised and disappointed" to be told by the FIA that they had broken cost cap rules for the 2021 season.
Formula 1's governing body finally gave out compliance certificates on Monday after delaying their announcements from last week. Of the 10 teams, Red Bull were the only ones the FIA said had overspent during last season. Aston Martin were also found guilty of a "procedural breach" but did not go over the cost cap.
But in a statement, Red Bull "noted" the FIA's findings but appeared unwilling to accept them. Instead, they still believe – as team principal Christian Horner said on many occasions last week – that they did not go over budget.
In a statement released on social media shortly after the FIA's announcement, the team said: "We note the findings by the FIA of 'minor overspend breaches of the financial regulations' with surprise and disappointment.
"Our 2021 submission was below the cost cap limit, so we need to carefully review the FIA's findings as our belief remains that the relevant costs are under the 2021 cost cap amount. Despite the conjecture and positioning of others, there is of course a process under the regulations with the FIA which we will respectfully follow while we consider all the options available to us."
The team's reaction fits in with earlier statements made by Horner, in which he appeared adamant that he did not expect his team to be implicated in any breach of the rules despite rumours to the contrary. "I'm absolutely confident in our submission," he said in Singapore.
"It's been through a process. It went in in March, in terms of [being] signed off fully by our auditors who are obviously one of the big three. And we believe that we are comfortably within the cap. So the FIA are following their process."
He did admit later, though, that because the rule is new there is the possibility it may be enforced in a way some teams do not expect. "There's always different interpretations to those regulations. So in the first year, it will be very interesting to see how that is applied. We've seen clarifications, even since the submissions were made, that apply to last year," he added.
"So it's always going to be a process of evolution. It's an enormous topic for the FIA to get their arms around, particularly when you look at the scale of the teams in the pit lane, many of which belong to even bigger conglomerates and organisations."
The FIA did not reveal anything about any potential punishments for the teams that were not in full compliance with the rules. Williams were given a £25,000 fine earlier this year for late submission of their paperwork on the topic, so a breach of the regulation is likely to incur a much more hefty penalty.
Sporting penalties are possible, meaning there is a chance Max Verstappen's maiden drivers' title could be in danger. But that does seem unlikely, with fines and the potential of lowering the cost cap for teams in the future other weapons in the FIA's armoury.
