@Arizona, your instincts are good to initially look for the incentives in the Rem reports.
As did @mikebrisy, including a check on option strike prices to see if mgmt could be (but aren't) elevating share prices with buy backs to push their options into the money - sneaky!
Incentives
This instinct reminds me of Munger's "Show me the incentive and I'll show you the outcome."
Digging into this further, the STI is all cash and based on operational (not share price) targets.
The LTI is paid in ZEPOs (Zero Exercise Price Options) - mgmt have a lot of discretion in the award of these each year and LTI has been creeping up in recent years, hopefully for the right reasons...
However these are paid to KMP's not Directors and made up just 12% of their total comp in 2023 (9-10% in 2022), so not really a factor.
Skin in the game
Separately Directors (who ultimately decide on the Buy Back policy) have skin in the game (mainly the Chair and MD) holding 5.7% / $19.1m between them.
So they will be among the beneficiaries of a higher share price and specifically buying support, although it would be a very bad look and potential red flag to be selling into or shortly after a buy back program.
Capital Allocation
On balance I still think the buy back is primarily to keep the starting price high for any potential negotiation - but also likely a good use of cash given their increasing FCF yield and reduced need / perceived opportunity for it to reinvest in the business (Capex / R&D).
Other potential uses for this would be M&A - they've done a bit of this in the past (ESG related) but probably not anything obvious for them to do as they've built out their product suite slowly over a long period of time to the point where some modules are de facto industry standards or becoming so.
Dividends - would not be Fully Franked due to carried forward tax losses. Deferred Tax Assets - from accrued losses sit at $3.2m and stable across 2022 and 2023.
They have no debt to pay down (only leases) - so either have to let the cash pile up and earn circa 4% interest before tax (they are now profit making so taxable) or buy back stock.
The hurdle for buying back stock is therefore an after tax opportunity cost of about 3%, so this seems like wise capital allocation by mgmt to me.
Disc: Held.
