The shareholders of Polygiene, the Swedish supplier of anti-viral solutions, have accepted a proposal to issue new shares to help finance the acquisition of Addmaster Holdings, its very profitable U.K.-based supplier of anti-microbial additives for hard surfaces, for SEK 374 million (€36.7m-$44.7m) in cash and shares. Polygiene, whose sales of Viraloff treatments for textiles are booming because of the Covid-19 pandemic, was founded in 2004 in a spin-off from the Perstorp Group following the outbreak of the SARS pandemic.
