Shanghai, China – May 5, 2025 – Nisun International Enterprise Development Group Co., Ltd (“Nisun International” or the “Company”) (NASDAQ: NISN), a technology-driven organization focused on transforming supply chain and agricultural logistics, today announced the signing of a USD $50 million corn supply agreement with Sichuan Yingdafeng Agricultural Technology Co., Ltd. (“Yingdafeng”).

Under the agreement, Yingdafeng will supply high-quality yellow corn over a 12-month period. All shipments will comply with national food safety and quality standards, supporting Nisun International’s expanding role in China’s agricultural supply chain.

“This agreement enhances our sourcing capabilities and reflects our commitment to building a resilient and efficient agricultural supply chain,” said Mr. Xin Liu, CEO of Nisun International.

In support of long-term shareholder value, Nisun International will continue executing its existing stock repurchase plan, reflecting the management team’s confidence in the Company’s performance and its belief that the current share price undervalues the business. The buyback strategy is designed to strategically deploy capital while reinforcing investor confidence.

“We remain focused on delivering consistent growth and maximizing shareholder returns,” added Mr. Liu. “Our business fundamentals are strong, and our strategic initiatives are aligned for long-term value creation.”
