Just Retirement is to spend millions on a restructure after a 50% plunge in annuity sales following March's Budget.
Just Retirement said the one off reorganisation, which will cost £5 million, is expected to save the group £14 million next year.
It also said it would invest an additional £5 million into the business over the year.
'Together, these steps will ensure that we are ready with appropriate new product and distribution offerings in April 2015 when the new regime begins,' the firm told the stockmarket.
Chief executive Rodney Cook (pictured) added: 'Although operating conditions have become much tougher since the Budget, with sales at around half of pre-Budget levels, we are rapidly adapting our model to the new environment. I am confident that by continuing to offer customers a fairer deal in retirement we can deliver further shareholder value.'
It is not clear whether the restructure will result on job losses.

In the three months to 31 March, individual underwritten annuity sales were up 34% year-on-year at £288 million.
It also saw record quarterly lifetime mortgage advances at £159 million, a rise of 128%.
Shares in the firm plunged by 36% in the hours after the Budget.
