They already have been, multiple times, nowadays they belong to Micro Focus.
In July 2018, Micro Focus International, SUSE's parent company since 2014, announced its plan to sell the business unit to a subsidiary of EQT Partners in the first quarter of calendar year 2019.[7][8] This acquisition was completed on 15 March 2019, making SUSE a standalone business. Under new ownership, their legal name is SUSE Software Solutions Germany GmbH.
I stand corrected, it is still owned by them in 75% though.
