LST has 3 divisions including a rapidly growing passive fire safety division (PFP) retrofitting specialist cavity closers to solve Grenfell Tower type risks, an Agtech division selling comprehensive solutions to food growers and a printed circuit board business providing bespoke products at relatively low volumes. The latter has effectively been a cash cow that has helped keep the lights on and offered steady growth post IPO, whilst the more recently acquired fire safety business offers huge growth potential with tens of thousands of buildings legally required to be made safe over the next few years and relatively few accredited competitors.
