The deal is done, provisionally. What most compliance teams still lack is a single document that converts the Omnibus political agreement into four concrete planning dates. That’s what this brief delivers.
Under the provisional agreement reached between the European Parliament, Council, and Commission, pending formal adoption and publication in the Official Journal, the deadline structure for EU AI Act obligations now looks like this:
August 2, 2026, Article 50(1) transparency rules take effect as scheduled
Standard transparency requirements under Article 50(1) are not covered by the reported deferrals. If your AI systems interact with natural persons, Article 50(1) disclosure obligations apply from this date. Nothing in the Omnibus changes that. Don’t expect a grace period here.
December 2, 2026, Article 50(2) synthetic content marking
Systems that generate or manipulate synthetic content and were placed on the EU market before August 2, 2026 get four additional months. The machine-readable marking obligation under Article 50(2) shifts from August 2 to December 2, 2026. Four months sounds reasonable. It isn’t much time if your labeling infrastructure isn’t built.
Warning
The provisional agreement is pending formal adoption by the European Parliament and Council, followed by Official Journal publication. The amended deadlines are not yet legally binding. Track formal adoption as the planning trigger, not the provisional agreement date.
December 2, 2027, Annex III standalone high-risk AI compliance
This is the big one for most enterprise AI deployers. Systems covered by Annex III, biometrics, employment screening, credit scoring, critical infrastructure, law enforcement applications, get a 16-month extension from the original August 2, 2026 date. According to the European Parliament’s confirmation of the agreement, standalone high-risk AI systems now face a December 2, 2027 compliance deadline. That’s 18 months from today.
August 2, 2028, Annex I product-embedded high-risk AI
AI components embedded in product-regulated categories, medical devices, radio equipment, lifts, machinery, have longer runway still. The Annex I compliance deadline shifts 12 months from the original August 2, 2027 date to August 2, 2028.
One addition, not a deferral: the Omnibus adds new Article 5 prohibitions banning AI-generated non-consensual intimate imagery (nudifiers) and AI-assisted CSAM. These aren’t deferred. They’re new absolute prohibitions that take effect with the agreement’s formal adoption.
One partially confirmed item: the provisional agreement is also reported to defer National AI Regulatory Sandbox obligations by 12 months to August 2, 2027, though this provision hasn’t been confirmed against official EU institutional text available to us.
Immediate Actions While Omnibus Is Pending Adoption
- Begin Annex III classification analysis for all AI systems, don't wait for OJ publication
- Confirm Article 50(1) transparency compliance for August 2, 2026, not deferred
- Assess Article 50(2) synthetic content marking infrastructure for December 2, 2026 target
- Track European Parliament and Council adoption vote dates
The catch is that “provisional” still matters here. The agreement requires formal adoption by both the European Parliament and the Council, followed by publication in the Official Journal, before any of the amended deadlines are legally binding. Organizations planning around the December 2027 date should track formal adoption as the trigger, not today’s announcement.
The real question is whether the 16-month Annex III extension creates genuine preparation time or a false sense of runway. Classification work, determining which of your systems fall under which Annex III category, can’t wait for the formal OJ publication. That analysis takes months, and the certification and documentation requirements that follow it take more.
Organizations that start Annex III classification now will be positioned to use the extension productively. Those that wait for formal adoption will find 18 months compresses quickly.
