Ann: Share Purchase Plan-TMX.AX, page-7

Looks to me like any selling could guarantee you get cut from getting any shares. Very smart strategy IMO also the ex-date has passed! See the Share Purchase Plan at the end of the announcement says - TMX’s discretion with regard to application

TMX may accept or reject any application under the Plan at its discretion. When determining if an application is to be accepted or rejected, or the amount (if any) by which to scale back an application, the Company may take into account a number of factors, including the size of an applicant’s shareholding, the extent to which Eligible Shareholders have sold or bought additional shares after the Record Date and the date an application was made

Without limiting the above, TMX may issue to any person fewer Shares than the person applied for under the Plan if the issue of Shares applied for would contravene any applicable law or the Listing Rules of ASX

If TMX rejects or scales-back an application or purported application, TMX will promptly return to the shareholder the relevant application monies, without interest
