Life insurance and pensions software firm Marlborough Stirling has announced the firm is up for sale and warned its recovery is taking longer than expected. Chairman Paul Fullagar, who was appointed only three months previously, is resigning having warned revenue will be less than expected this year. “Given this degree of short-term uncertainty, the board has concluded that shareholder value is likely to be optimised by pursuing joint venture or sale processes for some or all of the constituent parts of the group," said Marlborough Stirling.
