Sivantos last year spun out of Siemens, the huge German industrial conglomerate which restructured to focus on its core businesses. Siemens had long been one of the top three global hearing aid providers, and Sivantos, which is owned by a private equity group, still sells Siemens hearing aids while it is introducing its own products under its new Signia brand. Sivantos also acquired the Rexton hearing aid brand from Siemens as well as the HearUSA chain of hearing aid retail stores. It also recently acquired the Audibene online hearing care provider.
