How do we acquire interest in SpaceLink, page-4

As far as I'm aware, no specific information has been released regarding an IPO.

EOS has previously stated that they believe Spacelink could possibly be funded by a combination of free cash flow from EOS, supplier credit, and debt backed by forward contracts. If they can pull this off then there will be no IPO, Spacelink will be 100% owned by EOS, and your share in EOS will also be your share in Spacelink.

EOS have also mentioned a SPAC (Special Purpose Acquisition Company) as another way to fund Spacelink. This would allow EOS to combine their money with other investors in the SPAC. The SPAC (Let's call it SPACelink Holdings) would then fund Spacelink. In this case there would be no Spacelink IPO, and probably no SPAC IPO either as these things are normally raised privately. Using a SPAC provides flexibility for EOS in how much extra money is raised from external sources. I would expect EOS to try very hard to retain at least 51% ownership of the SPAC, and therefore Spacelink. If this is the chosen pathway then your share in EOS would also be your share of SPACelink Holdings, and therefore also your indirect share in Spacelink.

The fact that EOS has referred to some of the funding commitments it has received as "pre-IPO" instruments implies to me that SPACelink Holdings is the most likely pathway. I wouldn't read that as a commitment to do an IPO. Those things are expensive, and time-consuming.

If there is an IPO you would receive shares in the new company in proportion to EOS's interest in Spacelink and your interest in EOS diluted by any additional funds raised in the IPO. If you are not eligible to own shares in the new company then you would receive cash. Eligibility is determined by jurisdictional regulations. For example you will see most prospectuses issued here in Australia state that they are not for distribution in certain other jurisdictions. This is because of eligibility rules.
