My nutshell:
1. ARM gave a broad range of licenses to Nuvia to develop an ARM-based architecture for use in servers, with a license-fee to match this objective (probably a favorable one, because it's a field ARM aims to expand):
"Nuvia’s licensing fees and royalty rates reflected the anticipated scope and nature of Nuvia’s use of the Arm architecture. The licenses safeguarded Arm’s rights and expectations by prohibiting assignment without Arm’s consent, regardless of whether a contemplated assignee had its own Arm licenses."
2. Qualcomm acquires Nuvia with the intention to use the developed IP for (quote):
"powering flagship smartphones, next-generation laptops, and digital cockpits, as well as Advanced Driver Assistance Systems, extended reality and infrastructure networking solutions"
Sounds quite reasonable if the claim is validated: ARM gave favorable conditions to a startup which aimed to compete in a field where ARM is weak (servers). Now the biggest customer of the strongest revenue-market of ARM (mobile devices) has acquired that startup to repurpose their development and license to use in mobile devices, PCs, automotive, VR,...
