‘@dhubaibm – Interesting set of questions. Not sure anyone on this site would have the true answers you are seeking. These are questions best asked of the company itself and people with more direct knowledge of the transactions. Some reasons why a company may pursue such a spin-off or carve out are typically aligned with organizational strategy or potential governmental regulatory concerns (monopolies, conflicts of interest, etc.). Success factors of such a divestiture would also be aligned with the thesis for the transaction, so again, questions best asked of the company rather than solicitation of speculative responses on this forum.
Have you tried to connect with people from the company – email, phone, social media (i.e. LinkedIn)? How about contacting their investor relations department? Have they publicly shared any information with news media outlets reporting this pending IPO/spin-off/carve out? Perhaps some information may be found through these resources too that may shed some light on your question.
