European Commission Adopts Delegated Regulations on Disclosures and Trading Under MAR

Why It Matters

The changes reduce compliance burden for issuers while tightening transparency around material events, and they give managers more flexibility to trade, potentially improving market liquidity. Regulators also gain clearer tools to detect manipulation in an increasingly digital trading environment.

Key Takeaways

• Disclosures exemption for intermediate steps in protracted processes
• New list defines final events requiring timely MAR disclosure
• Trading rule expands manager exemptions during closed periods
• Designated venues added for order‑data exchange under Article 25a
• Manipulation indicators updated to reflect recent technical developments

Pulse Analysis

The Market Abuse Regulation (MAR) has been the cornerstone of EU market integrity since 2014, but rapid advances in trading technology and the growing complexity of corporate actions have exposed gaps in its original framework. Regulators responded by issuing delegated regulations that can be updated more swiftly than primary legislation, allowing the European Commission to fine‑tune disclosure and trading rules without a full legislative overhaul. This agility is crucial as cross‑border issuers and digital asset platforms demand clearer, more adaptable guidance.

The new disclosure regulation targets the cumbersome requirement to report every intermediate step in lengthy corporate processes, such as multi‑stage mergers or phased emissions‑allowance allocations. By exempting these interim actions and providing a concise list of final events that trigger mandatory disclosure, the rule aims to cut down reporting noise while preserving investor‑relevant information. It also introduces a structured approach for delayed disclosures when inside information diverges from the latest public communication, giving issuers a defensible pathway to manage market expectations without breaching MAR.

On the trading side, the amendment expands the scope of managerial exemptions during closed periods, acknowledging that senior executives often need to adjust personal portfolios without jeopardizing market fairness. The addition of designated trading venues for order‑data exchange under Article 25a enhances transparency of large trades, while the refreshed manipulation indicators reflect algorithmic and high‑frequency trading techniques that have become commonplace. Together, these updates aim to balance flexibility for market participants with robust safeguards, positioning the EU to maintain a level playing field as financial markets continue to evolve.
