Aston Villa, Chelsea, Newcastle United and Nottingham Forest have all been fined by UEFA for breaching financial sustainability regulations.
All four Premier League clubs fell foul of UEFA's squad cost rule, while Newcastle also failed to comply with the football earnings rule.
Villa have been fined €22.5m (£19.4m), of which €15m (£12.9m) is suspended pending their continued compliance over a three-year period that began with an initial fine in July last year.
In addition, Villa will face a restriction on the registration of new players for next season's Champions League campaign, with UEFA expected to confirm details of this shortly.
Chelsea have been fined €3m (£2.6m), of which €2m (£1.7m) is suspended. Forest must pay €2.5m (£2.2m), and Newcastle €3m (£2.6m).
Meanwhile, Strasbourg, part of Chelsea owners BlueCo's multi-club model, have also been fined €13m (£11.2m) for breach of squad cost rule. This could rise by €12m (£10.3m) if they fail to comply with their settlement agreement.
UEFA's statement read: "Regarding Aston Villa FC and Chelsea FC, which had already been sanctioned in the previous season, the CFCB First Chamber took into consideration the improving trend in their squad cost ratio between 2024 and 2025 in line with projections submitted as part of their settlement agreement.
"As a result, part of the fine is conditional upon the clubs continuing to significantly decrease their squad cost ratio in 2026."
The Magpies acknowledged the sanction and indicated they would work with the European governing body to ensure full, ongoing compliance moving forward.
The statement read: "Newcastle United has entered into a settlement agreement with UEFA following a breach of its financial sustainability regulations in the three-year period ending June 2025.
"Following an overspend in relation to UEFA's football earnings threshold, the club has worked closely and constructively with the Club Financial Control Body (CFCB) to swiftly resolve the matter.
"Accordingly, the club has accepted the three-year settlement, which includes a €3m euro financial penalty, with a further €7m suspended pending future compliance.
"In addition, UEFA has determined that the club will pay a further €3m due to breaching UEFA's 70 per cent Squad Cost Ratio (SCR) target in calendar year 2025.
"Newcastle United thanks UEFA for its careful consideration and is committed to full ongoing compliance."
