What Is an Appendix 3Y? The ASX Form That Tracks Director Share Transactions

An Appendix 3Y is a disclosure form that ASX-listed company directors must lodge whenever their interest in the company's securities changes. It's the mechanism that puts director share transactions on the public record — and the primary data source behind every transaction on AUDirectorPulse.

What triggers a filing

Under ASX Listing Rule 3.19A, a director must lodge an Appendix 3Y within five business days of any change to their relevant interests in securities. This includes:

• On-market purchases — buying shares through the ASX exchange using personal funds
• On-market sales — selling shares through the exchange
• Options exercises — converting previously granted options into shares
• Share issues — receiving shares as remuneration, under an employee share plan, or in a capital raising
• Off-market transfers — moving shares between related entities such as a family trust or SMSF

The same form covers all of these — which means not every filing carries the same signal.

Why on-market buys stand out

When a director buys shares on-market, they're spending real cash at the prevailing market price. No discount, no obligation, no remuneration structure. It's a voluntary, price-exposed decision made with their own money.

That's meaningfully different from receiving shares as part of a pay package or exercising options granted years ago at a lower strike price. Both show up in Appendix 3Y filings, but only the on-market buy represents a director choosing to put personal capital into the company at today's price.

Large on-market buys — or clusters of buying by multiple directors at the same company within a short period — are what most investors watch for.

What the form contains

Each Appendix 3Y records the director's name, the company, the date of the transaction, the number of securities, the price paid (for on-market trades), the nature of the change, and the director's total holding after the transaction. AUDirectorPulse parses each filing and structures this data so you can filter and browse by company, director, or transaction type without manually reading PDFs.

Where filings are published

All Appendix 3Y filings are lodged with the ASX and published on the ASX announcements platform, typically within five business days of the transaction. AUDirectorPulse aggregates them as they're filed.

Director transactions are public data, not investment advice. Directors buy and sell for many reasons, and past buying activity is not a reliable predictor of future price movements.
