Operating profit grew to £513,000, up 172% from a loss for the previous year of £706,000.
The events group attributed its performance to factors including a 52% growth in corporate events business; a "sharper focus on sales"; and a "considerable productivity improvement" of 23% - a measure of the ratio between gross profit and overheads.
Mike Davies, BI Worldwide’s managing director, said: "Without doubt, it is the hard work, commitment to quality, and loyalty of the whole team at BI Worldwide that has returned the business to a positive financial position.
"We are conscious that ‘one swallow does not a summer make' and continue to work hard to deliver further growth in the year ahead.
"However, we are pleased with the start we have made and are 7% ahead in the first quarter of the new financial year. We are also delighted that we have been able to give all associates a pay increase and bonus in line with the performance of the business."
