Alder contact

“When we invested in Powerbox, we recognised the Company’s strong name in the market, its long-term relationships with premium customers and large distribution network. Building on this, the management team managed to grow the custom design business, focus on premium distribution relationships, integrate two add-ons acquisitions and substantially improve profitability. Sales grew from SEK 300m to 400m and profitability developed from negative to substantial positive numbers”
