May 13 Trilogue Is the Last Realistic Window to Defer EU AI Act High-Risk Deadline

A third and potentially final trilogue session between the European Parliament, the Council of the European Union, and the European Commission is now locked in for 13 May 2026 — the last realistic slot to formally adopt the Digital Omnibus amendment before the August 2026 high-risk AI compliance deadline transforms from a distant regulatory target into an immediate legal obligation.

How the Negotiations Collapsed

Twelve hours of negotiations on 28 April ended without agreement, with the sticking point being technical rather than political. The three institutions had broadly aligned on the major commercial concessions embedded in the Omnibus — including a postponed compliance deadline for high-risk systems listed in Annex III (covering AI used in hiring, credit scoring, and critical infrastructure) and a simplified version of the Article 49 registration database. The dispute that killed the session was narrower: how to handle AI systems embedded in physical products already regulated by separate EU safety legislation, such as medical devices, industrial machinery, diagnostic equipment, and connected vehicles covered by Annex I.

The European Parliament favoured routing those AI systems through the relevant sectoral law, effectively exempting them from the AI Act's conformity-assessment architecture. The Council and Commission resisted, arguing that creating sector-specific carve-outs would fragment the horizontal framework the AI Act was designed to establish. MEP Michael McNamara publicly warned that moving AI governance into sectoral channels risked being "deregulatory rather than simplifying."

Civil society organisations echoed the concern. More than 40 groups filed objections arguing that Parliament's proposed carve-outs could remove meaningful accountability from high-stakes AI deployments in healthcare and critical infrastructure.

The May 13 Stakes

Legal analysts now characterise the compliance situation as binary: either a deal is reached by early summer — giving the Council time to publish the final text in the Official Journal before the Irish Presidency begins on 1 July — or the original AI Act timelines remain in force. Under that scenario, organisations deploying high-risk AI systems as defined in Annex III must comply fully with obligations including mandatory fundamental rights impact assessments, human oversight requirements, and technical documentation standards by 2 August 2026, roughly 90 days from today.

Probability estimates circulating among Brussels-based legal practitioners place a quick May 13 recovery at roughly 50%, a slower Q3 settlement under the Lithuanian Presidency at 25%, a split deal that separates Annex I and Annex III into separate tracks at 15%, and full stalemate at 10%.

The Annex I product categories — medical devices, machinery, diagnostics — are of particular commercial interest to German and northern European manufacturers, which may give the Council additional incentive to find a narrow compromise on conformity-assessment language without abandoning the horizontal framework entirely.

Immediate Compliance Implications

Regardless of the Omnibus outcome, Article 50 transparency requirements for generative AI systems are not under negotiation and become enforceable on 2 August 2026. Organisations planning to launch generative AI products in the EU market after that date must implement content marking and watermarking capabilities that satisfy the requirements now appearing in the second draft of the Code of Practice on AI-Generated Content.

For enterprises deploying high-risk AI, the uncertainty created by the stalled Omnibus presents a practical dilemma. Postponing compliance investments on the assumption the Omnibus will pass in time carries legal exposure if negotiations collapse again on May 13. Starting full compliance programmes now avoids that exposure but involves significant cost, particularly for smaller organisations.

What to Watch

If the May 13 session yields a text-level compromise on Annex I, the Omnibus could receive a final Council vote before the summer recess and reach the Official Journal by late June. That would give business approximately six weeks of confirmed transition time before August 2. If it fails again, the Lithuanian Presidency, which begins 1 July, will inherit the negotiation — but with the August deadline already active, enforcement would begin in parallel with ongoing legislative discussions, an uncomfortable precedent.
