Safe and Green shares surge 63.16% intraday after rebranding to RenX, focusing on engineered soils and renewable materials.

Safe and Green Development (NASDAQ:SGD) surged 63.16% intraday following the announcement of its corporate name change to RenX Enterprises Corp. and ticker symbol transition to RENX, effective December 19, 2025. The rebranding, highlighted in multiple news releases, underscores the company’s strategic pivot toward engineered soils, renewable-material production, and vertically integrated sustainable solutions. CEO David Villarreal emphasized the name change aligns with long-term growth in high-margin soil products and regenerative land-use, signaling a shift from its prior real estate development focus. The move reflects expanded operations at its Florida organics processing facility and plans for advanced milling technology, including a pending Micotec Mill installation. While the stock’s meteoric rise may also reflect optimism over recent revenue growth and debt reduction, the name change and strategic repositioning were the primary catalysts, with investors likely interpreting the rebranding as a positive step toward scalable, environmentally aligned revenue streams.
