On 28 November 2024 the Commission opened infringement procedures against 23 Member States for missing the NIS2 transposition deadline — pressure that makes national laws land on short notice.
Status note. This item records the procedural step of 28 November 2024. Infringement procedures evolve — check the Commission's infringement register for the current stage per Member State.
What changed
On 28 November 2024 the European Commission sent letters of formal notice to 23 Member States that had not fully transposed the NIS2 Directive by the 17 October 2024 deadline, opening infringement procedures. The Member States concerned had two months to respond and complete their transposition. A letter of formal notice is the first step of the infringement procedure; subsequent steps (reasoned opinion, referral to the Court of Justice) follow if a Member State does not comply.
Why it matters
The infringement wave tells you where NIS2 national laws are still coming — and that they will come under deadline pressure. Entities in late-transposing countries get the shortest runway between publication of the national law and its obligations biting; the directive text is the only reliable preparation baseline in the meantime.
Who is affected
Essential and important entities in the late-transposing Member States — most of the EU at the time of this action — and groups operating across several countries whose compliance timelines now diverge per jurisdiction.

What to check next
- Track the transposition status of each Member State you operate in
- Identify which of your group entities sit in late-transposing countries
- Prepare alignment work against the directive text now rather than waiting for the national law to force the timetable
- Review the Commission's infringement register for the current procedural stage per country
