Speedy Hire's profits have been dented following an investigation into the disappearance of equipment worth over £20m.
The Newton-le-Willows-headquartered company ruled out fraud in May when it announced the £20.4m asset write off.
As a result the firm's pre-tax profits were slashed from £29.1m to £1.8m in the 12 months to March 31, 2023.
