An advertising entrepreneur is hatching ambitious plans to build a global media empire after taking his marketing firm off the stock market. Sources said Marc Boyan was weighing a move to reach4entertainment enterprises plc (AIM:R4E), which he runs with former BBC boss Lord Grade, with his Miroma Group Limited. R4E said it would be better off as a private firm after warning that the impact of lockdown had been severe', effectively shutting down the West End and Broadway and putting concerts around the world on hold. It said not being listed would help it save costs, make strategic decisions faster, and could even help it raise cash. Investors who do not sell their holdings in the company before it delists will be left with shares that could be hard to sell. City sources said Boyan is considering combining R4E with his privately-owned Miroma once the de-listing is completed.
