Gem Diamonds reports a 36% decline in revenue to 98.4 million USD for 2025 and a net loss of 63.4 million USD (loss per share 0.68 USD). Causes were continued price weakness for rough diamonds, higher inventories, lower quality mix and fewer large stones sold; an impairment of 77.5 million USD on Letšeng contributed significantly to the result. Adjusted EBITDA was 3.9 million USD; the company launched a "Business Resilience Programme" in H2 2025 and plans to renew credit facilities before they expire in December 2026, but also expects a continued weak market in 2026. » Plus sur de.investing.com
