The Globe and Mail reports in its Friday, April 26, edition that activist Engine Capital intensified its campaign against Dye & Durham on Thursday, stating that its efforts to work with the board had failed. The Globe's Sean Silcoff writes that Engine, which owns 6.6 per cent of Dye & Durham stock, released a letter to shareholders Thursday signed by managing partner Arnaud Ajdler in which he said he was "compelled to publicly raise our concerns about Dye & Durham's underperformance and strategic missteps." Those include its underperformance relative to the TSX and Nasdaq Composite indexes over the past year, three years and since its 2020 initial public offering. Mr. Ajdler accused Dye & Durham of being a poor allocator of capital, saying it had paid too much for acquisitions, bought back shares and months later issued stock at a lower price. He also said it mismanaged the refinancing of $345-million in convertible debt and made "unnecessary" expenditures totalling $134-million related to acquisition, restructuring and other costs over the past three years. That "exorbitant" outlay "reflects the frenetic pace of capital market activity under the current board."
