In August 2015 LDC completed a significant investment to support the £23m management buyout of BOFA International (BOFA) to drive its international growth and product development.

In 2016 BOFA and LDC were delighted to pick up the 'Deal of the Year' at the prestigious Thames Valley Deal Awards, the deal was recognised due to the future potential of the opportunity for growth within the business.

In 2017 BOFA received a Queen’s Award for Enterprise for Innovation for it’s unique and revolutionary Intelligent Operating (iQ) system.

In 2018 BOFA was recognised for its fast-growing international sales in The Sunday Times HSBC International Track 200. The business was listed at number 163, thanks to the success of its US facility and German office, which has helped to drive international sales to over £21m. The business was also named Company of the Year at BDO's Central South Mid-Market awards they were commended by the judges for "strong leadership, vision and innovation, as well as business planning that focused on investing in new technologies."

In September 2018 LDC completed the sale of BOFA to NYSE-listed Donaldson Company, Inc. (NYSE:DCI), the leading worldwide manufacturer of filtration systems and parts. Donaldson agreed to acquire an 88% stake in BOFA for £79m valuing the business at £90m and marking an exit for LDC.

During the partnership revenues have almost doubled, thanks to continued investment in the company’s infrastructure to support the businesses’ global growth strategy. BOFA also established its first European on-the-ground presence with an office in Hamburg, Germany, invested in its US-based operation in Illinois, which since delivered 23% year-on-year growth and the business increased its employee numbers by more than 50%.


Innovation and customer service has long been at the heart of our ethos, and with the additional capital and expertise LDC has brought on board we've been able to elevate the business on the global stage, whilst keeping a steady momentum of new products in the pipeline so we remain at the forefront of the industry.
