Insider‑trading Risks in M&A: What South African Deal Teams Must Know Under the Financial Markets Act

Last reviewed: 8 July 2026

Every public‑company acquisition or notifiable merger in South Africa creates a window of acute insider‑trading exposure. The Financial Markets Act 19 of 2012 (FMA), principally Sections 78 and 81, imposes strict prohibitions on dealing, tipping and misleading disclosure that apply to every person on a deal team, from the board and its advisers down to the data‑room administrators who handle price‑sensitive information. With the FSCA stepping up enforcement activity through early 2026 and A2X Markets publishing updated trading‑rule directives that affect dual‑listed targets, the compliance landscape for insider trading in M&A in South Africa has shifted materially.

This guide provides a practitioner playbook, checklists, templates, annotated examples and a step‑by‑step process, designed to be used from the first confidential approach through to post‑closing recordkeeping.

Quick Answers for Deal Teams

What does Section 78 of the FMA prohibit?
Section 78 prohibits any person who has inside information from dealing in the listed securities to which that information relates, from encouraging another person to deal, and from disclosing inside information to anyone who might reasonably be expected to deal. Inside information is specific, non‑public information that would likely have a material effect on the price of a security.

What does Section 81 of the FMA prohibit?
Section 81 prohibits any person from making a statement, promise or forecast that is misleading, false or deceptive in connection with securities, whether in a SENS announcement, circular, press release or oral briefing. It also prohibits the reckless or negligent dissemination of such information.

What should deal teams do immediately?
The moment information becomes price‑sensitive: (1) compile an insider list, (2) issue written trading restrictions to every person on that list, (3) draft board resolutions authorising controlled disclosure, and (4) ensure all SENS wording is reviewed by legal counsel for Section 81 compliance. The eight‑step playbook later in this article provides the full sequence.

What the Financial Markets Act Requires in M&A

The FMA is the primary statute governing market abuse in South Africa. For M&A practitioners, two provisions dominate the risk landscape: Section 78 (insider trading) and Section 81 (false or misleading statements). Both carry administrative penalties imposed by the FSCA and may also give rise to civil claims by affected investors. Understanding the precise elements of each prohibition is the first step toward a defensible compliance framework for insider trading M&A South Africa transactions.

Section 78, Elements, Defences and Examples

Section 78 creates three distinct prohibitions. First, an insider who possesses inside information may not deal, directly or indirectly, in the securities to which that information relates. Second, an insider may not encourage or cause another person to deal. Third, an insider may not disclose inside information to any other person, unless the disclosure is made in the proper performance of the insider’s duties.

The statute defines an insider broadly. It includes directors and officers of the issuer, persons who have access by virtue of their employment or professional engagement, and any person who obtains inside information, even second‑ or third‑hand. In an M&A context, that means legal advisers, accountants, data‑room providers, company secretaries, investor‑relations consultants and even external printers of circulars can all fall within the definition.

Defences are narrow. Section 78 provides a limited safe harbour where the insider can prove, among other things, that the dealing was not motivated by the inside information and that no unfair advantage was gained. In practice, the safest approach is to prohibit all dealing once a person is placed on the insider list.

Section 81, False or Misleading Statements and Communications

Section 81 is often overlooked by deal teams, yet it creates significant liability for anyone responsible for public communications about a transaction. The section prohibits making or publishing any statement that is misleading, false or deceptive regarding a material fact, if the person knows or ought reasonably to know that the statement is misleading. It also prohibits reckless or negligent publication of such statements.

In M&A, the risk arises most commonly in SENS announcements, cautionary notices, scheme circulars and investor briefings. Overly optimistic synergy estimates, selective disclosure of conditions precedent, or failure to update a cautionary notice when circumstances change can all trigger Section 81 exposure.

2026 Rule Changes and Enforcement Signals, What Changed and Why It Matters

The regulatory environment for insider trading in M&A in South Africa has tightened appreciably in 2026. Two developments demand deal‑team attention: updated trading rules published by A2X Markets and an acceleration in FSCA enforcement activity.

A2X Trading Rules, Key Points for M&A

A2X Markets, now a significant secondary exchange for many JSE‑listed issuers, published updated trading rules and directives in early 2026. The practical effect for M&A is threefold. First, deal teams must now account for A2X‑specific trading windows when imposing blackouts, a freeze on JSE trading alone is insufficient where the target is dual‑listed on A2X. Second, A2X directives require co‑ordinated announcements; a SENS release must be matched by a contemporaneous A2X market notice to avoid information asymmetry between exchanges. Third, the speed of intra‑day trading on A2X means that even short delays in imposing trading restrictions after information becomes price‑sensitive can expose insiders to liability.

Industry observers expect that the practical consequence of these changes will be tighter, more prescriptive blackout protocols and a growing need for deal teams to appoint a dedicated compliance co‑ordinator responsible for multi‑exchange notification.

FSCA Enforcement Pattern 2024–2026

The FSCA has published enforcement actions through its Enforcement Matters page at an increasing rate. The regulator’s willingness to impose substantial administrative penalties, and to refer matters to the Financial Services Tribunal, signals that insider‑trading enforcement is no longer limited to the most egregious, public scandals. The Steinhoff / Jooste proceedings remain the highest‑profile example: the FSCA brought administrative penalty proceedings under Section 78 against former executives in connection with dealing while in possession of inside information relating to the group’s accounting irregularities. More recently, the FSCA has turned its attention to smaller transactions and mid‑market deals, pursuing individual directors, connected persons and even advisers who traded during sensitive periods.

Early indications from the first quarter of 2026 suggest a pattern of proactive surveillance rather than reactive investigation, with the regulator cross‑referencing trading data against SENS announcement timelines to identify suspicious activity. Deal teams should assume that every notifiable merger will attract some level of post‑hoc regulatory scrutiny.

Common M&A Scenarios That Create Insider‑Trading Risk

Market‑abuse risk in M&A is not confined to the classic “director tips a friend” scenario. Below are the situations that most frequently create exposure, drawn from enforcement outcomes, the JSE Insider Trading Booklet and advisory practice.

Target‑Side Risks

• Board leakage before a formal approach. A director mentions an unsolicited indicative offer at a social event. Any person who receives that information becomes an insider and must not deal.
• Working‑capital and due‑diligence disclosures. Detailed financial information shared in a virtual data room is almost always price‑sensitive. Every recipient, including junior analysts and IT administrators with access, must be placed on the insider list.
• Selective investor briefings. Target management meets major shareholders to “sound out” appetite for a scheme. If deal‑specific information is disclosed, those shareholders become insiders and must be notified in writing.
• Delayed cautionary announcements. A target board decides to “wait and see” whether an approach becomes firm before publishing a cautionary. The delay increases the window during which insiders may inadvertently deal.

Bidder‑Side Risks

• Pre‑announcement stake building. A bidder purchases target shares in the market before announcing an offer. If the bidder already possesses inside information about the proposed transaction, those purchases contravene Section 78.
• Synergy‑estimate communications. Overstating expected cost savings in a SENS announcement or press conference can trigger Section 81 liability if the estimates lack a reasonable basis.

Adviser and Employee Risks

• Personal account dealing by advisory staff. An analyst at the sponsoring broker buys shares in the target before the formal announcement. This is the scenario the FSCA most commonly investigates.
• Informal tipping within a firm. Information shared between “Chinese‑walled” departments, whether accidentally or deliberately, can create liability for both the tipper and the recipient if either deals.

Deal‑Team Playbook, Immediate Steps When a Transaction Is Live

The following eight‑step playbook is designed for in‑house counsel, corporate secretaries and transaction lawyers managing insider trading M&A South Africa compliance from the moment a transaction becomes real. It can be adapted to suit both bidder and target perspectives.

Step 1, Identify insiders and create the insider list. As soon as information about the transaction becomes specific and price‑sensitive, compile a list of every natural person and legal entity with access. Record each person’s full name, identity or passport number, role in the transaction, and the date and time they first received inside information. Update the list in real time as new persons are granted access.

Step 2, Implement trading blackout and written instructions. Issue a written notice to every person on the insider list confirming that they may not deal, directly or indirectly, in any securities of the target (and, where relevant, the bidder) until a public announcement is made or the transaction is terminated. The notice should identify the relevant securities, state the statutory basis (Section 78 of the FMA), and require written acknowledgement of receipt.

Step 3, Pass board resolutions authorising controlled disclosure. The target’s board (and the bidder’s, where applicable) should pass a formal resolution authorising specific persons to share inside information with named recipients, advisers, financiers, regulators, on the basis that such disclosure is necessary for the proper performance of their duties. This creates the foundation for the safe‑harbour defence under Section 78.

Step 4, Require adviser NDAs and control data‑room access. Every external adviser, legal, accounting, financial, environmental, technical, should execute a non‑disclosure agreement that expressly references the FMA prohibitions and imposes equivalent trading restrictions on the adviser’s personnel. Virtual data‑room access logs should be maintained and exported at each milestone.

Step 5, Draft vendor/bidder disclosure covenants. The sale and purchase agreement or implementation agreement should include mutual covenants confirming that each party will comply with insider‑trading obligations and will not selectively disclose deal information outside the agreed insider list.

Step 6, Conduct monitoring and trading surveillance. Designate a compliance officer or external counsel to monitor trading in the relevant securities (and derivatives) from the date the insider list is first compiled. Cross‑reference any unusual trading patterns against insider‑list membership and data‑room access logs.

Step 7, Co‑ordinate FSCA and exchange notices. If the transaction requires a notifiable merger disclosure, co‑ordinate the timing so that the SENS announcement, any A2X market notice and any regulatory filing are published simultaneously. Staggered disclosure creates an information gap that can give rise to both market‑abuse risk and regulatory criticism.

Step 8, Maintain post‑closing records. Retain the insider list, all trading‑restriction notices, acknowledgement of receipt forms, data‑room access logs, board resolutions and SENS drafts for a minimum of five years after the transaction closes. These records are the deal team’s primary defence if the FSCA opens an investigation.

Sample Insider‑List Fields

Example Board Resolution and SENS Wording

Board resolution excerpt (annotated): “The board hereby authorises [Name], [Name] and [Name] to disclose information relating to the proposed transaction to [Named Adviser] for the purpose of obtaining financial, legal and tax advice, and notes that such disclosure is necessary for the proper performance of the company’s duties in relation to the proposed transaction. Each person so authorised shall ensure that the recipient executes the prescribed NDA and is placed on the company’s insider list prior to any disclosure.”

SENS cautionary notice excerpt (annotated): “Shareholders are advised that the company is engaged in discussions that, if successfully concluded, may have a material effect on the price of the company’s securities. Shareholders are therefore advised to exercise caution when dealing in the company’s securities until a further announcement is made. The company is under no obligation to proceed with any transaction and there can be no certainty that any transaction will be concluded.” This wording avoids the Section 81 risk of creating a misleading impression of certainty while still providing the required cautionary notice. Note the absence of forward‑looking synergy estimates or indicative pricing, both of which could create liability if they prove inaccurate.

Practical Templates and Annotated Examples

Effective compliance depends on having the right templates deployed before a deal gathers momentum. The following assets are designed for immediate use in South African M&A transactions and address the core requirements of the FMA insider‑trading regime.

• Insider‑list template (spreadsheet). A structured spreadsheet containing the fields set out in the table above. Populate it from the first confidential meeting and update it each time a new person receives access. Export and archive a time‑stamped version at every transaction milestone (LOI signing, data‑room opening, board approval, announcement).
• Trading‑restriction notice (letter template). A one‑page letter addressed to each insider, identifying the relevant securities, citing Section 78 of the FMA, prohibiting all dealing (including derivatives and CFDs) and requiring a signed acknowledgement. Include a clause confirming that the restriction remains in force until written notice of termination is issued by the company secretary or compliance officer.
• Board resolution template. A resolution authorising controlled disclosure to named advisers, confirming compliance with the “proper performance of duties” safe harbour, and mandating the maintenance of the insider list. The resolution should be minuted separately from general board minutes to ensure easy retrieval.
• SENS template (cautionary and firm‑intention announcements). Pre‑drafted cautionary and firm‑intention SENS announcements with annotated margin notes highlighting the Section 81 risk zones, pricing language, synergy estimates, conditions precedent and forward‑looking statements. Each template includes a sign‑off block for legal counsel.
• Sample email to insiders. A short, clear email to be sent simultaneously with the trading‑restriction notice, confirming the insider’s obligations in plain language and providing a direct contact for questions. Draft the email to be understood by non‑lawyers, data‑room administrators, IT staff and junior analysts are as much at risk as directors.

For transactional practitioners dealing with related conveyancing changes in South Africa, awareness of the broader regulatory framework for commercial disclosure is equally important. Similarly, entities operating in regulated sectors such as gambling licence holders in South Africa face overlapping disclosure and trading obligations that must be co‑ordinated with FMA compliance.

Enforcement, Sanctions and Litigation Risk, What Happens if the Rules Are Breached

The consequences of non‑compliance with Sections 78 and 81 are severe and have become increasingly tangible as FSCA enforcement accelerates.

Typical Administrative Penalty Calculation

The FMA empowers the FSCA to impose administrative penalties for contraventions of Sections 78 and 81. The penalty calculation typically takes into account the profit made or loss avoided by the insider, the seriousness of the contravention, the degree of co‑operation with the investigation and any history of prior contraventions. There is no statutory cap expressed as a single rand figure, the FSCA has discretion to impose penalties that reflect the full benefit derived from the insider trading, plus an additional punitive component.

Persons subject to administrative penalties may appeal to the Financial Services Tribunal, which has the power to confirm, set aside or vary the FSCA’s decision. Tribunal proceedings are quasi‑judicial, and decisions are reported and available on the FSCA’s website.

Civil Remedies and Private Litigation

Beyond administrative penalties, Section 82 of the FMA creates a civil right of action. Any person who dealt in securities at a price that was affected by insider trading may claim compensation from the insider. In practice, these claims are typically pursued by institutional investors through class‑action or representative proceedings. The reputational damage of a public insider‑trading finding is often as costly as the financial penalty, directors may face disqualification, and advisory firms risk losing regulatory licences.

The Steinhoff group litigation remains the most significant illustration: FSCA enforcement proceedings under Section 78 ran in parallel with massive civil claims by shareholders in multiple jurisdictions. The likely practical effect of this precedent is that any future insider‑trading finding in a major M&A context will trigger both regulatory and civil proceedings.

Insider Trading M&A South Africa: Cross‑Border and Multi‑Exchange Issues

Where a South African target is dual‑listed, on both the JSE and A2X, or on the JSE and an overseas exchange, deal teams must navigate overlapping regulatory regimes. The following checklist addresses the core co‑ordination issues.

Co‑ordinating Exchange Rules

• Align blackout windows. Ensure that trading restrictions apply to all exchanges simultaneously. A blackout that covers JSE trading but not A2X (or vice versa) is ineffective and creates enforcement risk.
• Synchronise announcements. The SENS announcement on the JSE must be matched by a contemporaneous market notice on A2X. Where the target is listed overseas, confirm the equivalent announcement obligations with local counsel.
• Apply the strictest standard. Where two exchange rule sets apply, default to the more restrictive requirement for insider lists, blackout periods and disclosure content.

When to Notify Other Regulators

• Overseas securities regulators. If the target is listed in London, the FCA’s Market Abuse Regulation (UK MAR) applies in parallel with the FMA. Deal teams must confirm compliance with both regimes.
• Competition authorities. Notifiable merger disclosure to the Competition Commission is a separate obligation but should be co‑ordinated so that the timing of public announcement does not create an information gap.
• Sector regulators. Transactions involving regulated entities (banks, insurers, telecommunications providers) may require prior regulatory approval. Selective disclosure to a sector regulator is permissible but must be documented and added to the insider list.

Conclusion, Five Actions Every Deal Team Should Take Today

Managing insider trading M&A South Africa compliance is not an afterthought, it is a core transaction workstream that must begin at the earliest stage of a deal. The five non‑negotiable actions are:

1. Compile the insider list from the first confidential meeting and update it in real time.
2. Issue written trading‑restriction notices to every insider and obtain signed acknowledgements.
3. Ensure all SENS announcements and public communications are reviewed by legal counsel for Section 81 compliance before release.
4. Co‑ordinate blackout windows across all exchanges on which the target’s securities are traded, including A2X.
5. Retain all compliance records, insider lists, notices, data‑room logs, board minutes, for a minimum of five years post‑closing.

Deal teams operating in South Africa’s commercial transactions space should treat these steps as standard operating procedure. The cost of non‑compliance, administrative penalties, civil liability, reputational damage and potential director disqualification, far outweighs the administrative burden of a well‑run insider‑trading compliance programme.
