Your question is from a long-gone era, when it was all about the "Linux distribution" as such (a time when I myself still worked for one of those big Linux companies). These days that's just a necessary but in the end secondary item. Instead the business is all about "enterprise stuff": clusters, storage, cloud, SAP, devops, HPC - i.e. "solutions". The Linux distribution merely is the vehicle and the basis, the actual business is well on top of it though, on another level. Check out what redhat.com and suse.com present on their respective homepages (no need to go deep, just the headlines - the SuSE pages show it a bit better I think, open the "Products & Solutions" menu on suse.com for an overview). I follow a few people I knew at SuSE and whenever they post something on social media it's cluster these, high availability stuff that, distributed storage here, containers there. It's never about the "boring" Linux OS level any more, always about software and solutions on top of it.
By the way, I just checked the job listings (https://www.suse.com/company/careers/) to see what they are up to, and there are 320 open positions? Really? Did they grow that much? When I left the Linux world almost 15 years ago that was about the total size of that company, that was just a few years after Novell had acquired it. It confirms the impression I had from loosely following some SuSE engineer's social media posts, getting handed over to new owners again and again does not seemed to have hindered them from growing quite a bit. Wikipedia says they have a thousand employees now.
