Cricket Australia's Test naming rights sponsor has torn up its deal as player sponsors also jump ship following the ball-tampering scandal.
Investment firm Magellan said the conspiracy in the South African Test series was "so inconsistent with our values", it had to end its three-year deal.
The deal with the ASX-listed financial services provider was only signed in August 2017.
"We were delighted with the recent Magellan Ashes Series sponsorship and it is with a heavy heart that we have to end our partnership in these circumstances," co-founder and chief executive Hamish Douglass said in a statement to the stock market on Thursday.
ASICS is among the player sponsors to scrap deals.
