@Fereguru the debt structuring of Siteminder will change significantly following the listing as you will see much of it involves derivative financial instruments utilising convertible preference shares that are rewarding early investors. That’s why you will notice ~85% (~520m) of the raised funds are directed towards payments to selling shareholders which from a quick glance should reduce much of the debt to nil.
However, this is not financial advice (VIP) and I would suggest you do a much deeper dive and speak to your accountant to get approved financial advice so you fully understand the numbers.
In general companies typically IPO to pay down debt, reward early investors and to access capital for growth. This does not guarantee that the shares will pop on listing especially, if the market thinks the IPO is fully priced. Most of the time the pre-ipo beneficiaries are the ones who benefit most as they get multiple opportunities to get a capital appreciation especially if the listing actually takes place.
PS. On another note I see major investors involve BTI, Black-rock and Aussie Super.
