Wigan shirt sponsor Premier Range will withdraw from their deal with the club following the appointment of Malky Mackay.
Mackay is currently being investigated by the Football Association for sending offensive texts, causing Wigan to be heavily criticised for hiring him.
Premier Range told the BBC: "Unfortunately, their recent appointment of Malky Mackay has put us in a position that we find untenable.
"Mr Mackay is currently under investigation by the FA for sending text messages that are at odds with the general ethos here at Premier Range - and, it would seem, Cardiff and QPR feel the same as us.
"The texts Mr Mackay has admitted to sending are wholly unacceptable - and the thoughts expressed within them are a shocking reminder of a past we thought football had left behind.
"A team that would employ a man who expresses views such these is not the kind of team Premier Range wish to deal with."
