Valtteri Bottas is taking a personal sponsor with him from Williams to Mercedes.
Throughout his career, the 27-year-old has been backed by Finnish industry conglomerate Wirhuri, which had prominent signage on Williams's livery.
Now that Bottas is moving, Finnish broadcaster MTV has revealed that Wirhuri is changing camps too.
The report says that Wihuri has signed a one-year sponsorship deal with Mercedes, in line with Bottas's new contract.
A Wihuri spokesperson said "everything worked well" with the now-concluding partnership between the company and Williams.
