Among other clients, HPE is a giant defense contractor supporting military hardware and software.
HPE also inherited HP's research labs, which Dell never quite had anything similar too, and medical division where they make a lot of very important medical/hospital devices.
ETA: HP at one point was much more similar to GE than Dell, and HPE is all the "fun" stuff that wasn't Dell-like. (The Dell like side is what got spun off into "new" HP.)
