Management Commentary:

“Ostrom Climate delivered a strong third quarter, with solid progress under our refined strategy and sustained momentum in our trading business,” said Navdeep Dhaliwal, Chairman and CEO of Ostrom Climate. “Revenue of $6.1 million and a return to profitability reflect the strength of our high-integrity VER trading and disciplined execution. We also continued to strengthen our balance sheet by reducing promissory note debt. Looking ahead, we remain focused on further balance sheet improvement and advancing key projects, including the UPRIIS Climate-Smart Rice Project and the expansion of our Canadian project pipeline, which we believe will drive long-term shareholder value.”
