Reach4Entertainment Enterprise PLC (LON:R4E) cautioned a staff restructure would affect this year’s results.
Terrorist incidents in London and Manchester had affected trading and the firm said one-off costs would take a further £1mln off profits in 2017.
Marc Boyan took over as chief executive in July, with Michael Grade becoming non-executive chairman.
They have set out a strategy to expand into promoting non-theatre productions and new geographic markets.
The switch of focus is expected to contribute to improved group profitability in 2018.
Boyan added Reach4 occupies strong market positions in the leading theatre markets of London and New York and can build upon these and expand beyond them.
