MAR Article 17: Disclosing Inside Information

Key Takeaways

• MAR inside information disclosure requires issuers to publish price sensitive news as soon as possible under Article 17.
• Disclosure can be delayed only if three conditions are met, including no risk of misleading the public.
• A common mistake is delaying disclosure without keeping the required records or reviewing the conditions.
• Prompt, equal disclosure keeps all investors on the same footing and underpins fair pricing.

What It Is

This duty sits in Article 17 of the Market Abuse Regulation, Regulation (EU) No 596/2014, known as MAR. It applies to issuers whose financial instruments are admitted to trading on EU venues.

The rule is direct: an issuer must inform the public as soon as possible of inside information that directly concerns it. Inside information is precise, non public information that, if released, would likely have a significant effect on the price. The disclosure obligation makes sure such news reaches all investors at the same time, rather than seeping out to a privileged few.

The Intuition

Imagine a company learns it has won a contract that will transform its earnings. If only insiders know, they can trade ahead of everyone else, and the share price drifts on whispers rather than facts. Ordinary investors are left buying or selling against people who know more.

Article 17 fixes this by forcing the company to tell everyone at once. Prompt public disclosure collapses the information gap, so the price adjusts in the open and no one trades on a hidden advantage. The narrow option to delay exists because there are moments, such as the middle of a delicate negotiation, when instant disclosure would damage the company and could mislead the market. The rule lets the company wait, but only under strict guardrails.

How It Works

The default is immediate disclosure. As soon as inside information that directly concerns the issuer exists, it must be made public as soon as possible, through means that allow fast and complete access by the public, and posted on the issuer's website for a set period.

Article 17(4) permits a delay only if all three conditions hold at once. First, immediate disclosure would likely prejudice the issuer's legitimate interests. Second, the delay is not likely to mislead the public. Third, the issuer can ensure the confidentiality of the information. If any condition fails, the news must be released.

A delay is not a quiet decision. The issuer must keep records showing how each condition was met and must monitor whether they still hold. The moment the conditions stop applying, for example if the information leaks, the issuer must disclose as soon as possible. When the delayed information is finally published, the issuer must notify the competent authority that disclosure was delayed and, if asked, explain how the conditions were satisfied.

Protracted processes, which unfold in stages such as a multi step negotiation, can generate inside information at intermediate steps, not only at the end. Issuers must assess each significant stage, which is where delay provisions are most often used.

Worked Example

A listed manufacturer is negotiating a major acquisition. Partway through, the deal becomes precise enough that, if known, it would move the share price. At that point inside information exists.

Announcing the half finished deal would likely wreck the negotiation, harming the issuer's legitimate interest. The company judges that staying silent will not mislead the market, and it can keep the talks confidential through insider lists and tight controls. All three Article 17(4) conditions are met, so the issuer delays disclosure, recording its reasoning and reviewing it as the talks progress.

If the negotiation leaks to the press, confidentiality is broken, the third condition fails, and the company must disclose as soon as possible. When the deal is eventually announced, the issuer notifies the regulator that disclosure had been delayed and, on request, explains how the conditions were met during the delay.

Common Mistakes

1. Delaying without documentation. A valid delay requires records proving all three conditions were met and monitored. Issuers that delay informally, without a paper trail, cannot defend the decision if challenged.

2. Forgetting to disclose once conditions fail. A leak or a change in circumstances can break a condition, especially confidentiality. When that happens the news must be released immediately, yet some issuers keep waiting on a delay that no longer applies.

3. Treating disclosure as discretionary timing. The default is as soon as possible, not when convenient. Holding price sensitive news to suit a results calendar or a roadshow breaches the rule unless a valid delay applies.

4. Missing inside information in protracted processes. A staged negotiation can create inside information at intermediate steps, not just at signing. Assessing only the final outcome causes issuers to miss earlier disclosure or delay triggers.

5. Skipping the regulator notification. After a delayed disclosure, the issuer must notify the competent authority that the release was delayed. Overlooking this step is a separate failing from getting the timing right.

Frequently Asked Questions

What is MAR inside information disclosure in simple terms? MAR inside information disclosure is the rule that a listed company must announce price sensitive news to the public as soon as possible. It stops insiders trading on news before everyone else hears it.

How does MAR inside information disclosure affect investment decisions? It ensures material news reaches all investors at the same time, so prices reflect facts rather than leaks. Investors can rely on prompt announcements rather than fearing they trade against better informed insiders.

What is a real-world example of MAR inside information disclosure? A company in secret acquisition talks reaches a point where the deal would move its share price. It may delay disclosure under strict conditions, but must announce immediately if the talks leak.

How can issuers handle MAR disclosure effectively? Identify inside information early, disclose as soon as possible by default, and only delay when all three conditions are met and documented. Review the conditions continuously and notify the regulator after any delayed release.

How is MAR inside information disclosure different from the wider Market Abuse Regulation? Article 17 is the specific duty to publish price sensitive news. The wider Market Abuse Regulation also bans insider dealing, unlawful disclosure, and manipulation. Disclosure is one obligation within the broader anti abuse framework.
