In early 2021, after operating for less than two years, it was taken over by National Australia Bank (NAB), and merged into its UBank subsidiary.[9] This was approved by the Australian Competition & Consumer Commission, despite concerns about reducing competition.[10] In October 2021, after the take-over by NAB, Robert Bell stepped down as CEO, to be replaced by Philippa Watson, CEO of UBank, who combined the roles of CEO of both NAB subsidiaries.[4][11] The brand was retired in May 2022,[12] becoming part of the newly rebranded "ubank."
According to NAB, the "visual identity, technology, and innovation capability of 86 400" was adopted by ubank.[13]
