NYSE:OBDCII 19 November 2025

April 12, 2026, 9:04 AM EDT. Rio Tinto Group is exploring the sale of its U.S. boron assets, attracting over a dozen potential buyers, as part of a portfolio reshaping under new leadership. Simultaneously, its Richards Bay Minerals unit has inked a long-term solar power purchase agreement in South Africa, linked to the Bolobedu solar farm, supporting the company's decarbonisation goals and enhancing its ESG profile (environmental, social, governance criteria). The mining giant's shares have risen 3.4% last week and 22.7% year-to-date, trading above analyst target prices by around 4.5%. The boron asset sale could alter Rio Tinto's critical minerals exposure and unlock capital for new priorities. Investors should monitor how divestment proceeds and the renewable energy deal affect future earnings, especially given the current 16.1x price-to-earnings ratio and a dividend yield at 4.06%, which may face coverage risks.
