Ann: Notification of cessation of securities - RDG, page-2

Hmmm, very interesting that these options , expiring in 2026 have been cancelled.
All up, circa 27.5 million oppies just bit the dust. The expired portion certainly makes sense, but not so much the 12 million that don't expire until January and December next year. They were issued as remuneration, and cancelled by "mutual consent".
Could this simply be a case of tidying up the register in time for the end of financial year auditing and reporting?
Or a wee precursor to a change of control event - pure speculation / wishful thinking on my behalf
