FOR IMMEDIATE RELEASE

Professional Diversity Network Advances AI Infrastructure Strategy with NVIDIA B300 System Order

CHICAGO, October 6, 2026 — Professional Diversity Network, Inc. (NASDAQ: IPDN) (“IPDN” or the “Company”) today announced a significant step in the development of its artificial intelligence (“AI”) infrastructure business through its wholly owned subsidiary, PDN Intelligence, Inc. (“PDN Intelligence”).

The Company has placed an order with AMAX Engineering Corporation (“AMAX”) on behalf of PDN Intelligence for one NVIDIA B300-based AI computing system and has paid 50% of the purchase price, with the remaining balance payable before shipment. PDN Intelligence is expected to acquire and hold title to the system before it is placed into service.

The order marks an important milestone in the Company’s execution of its AI infrastructure strategy and represents its initial investment in next-generation graphics processing unit (“GPU”) computing infrastructure.

The system is intended to support high-performance AI workloads, including AI model training, inference and other compute-intensive applications. Following delivery, installation and acceptance, the system is expected to be deployed at a third-party data-center facility and made available for commercial AI compute services.

PDN Intelligence will serve as the Company’s platform for developing and operating this business.

“We are moving from strategy to execution,” said Yiran Gu, Chief Executive Officer and Chief Financial Officer of Professional Diversity Network. “By placing our initial order and committing capital toward next-generation AI computing infrastructure, we are establishing the foundation for PDN Intelligence’s operations.”

“We believe demand for advanced computing capacity will continue to create opportunities across the AI ecosystem,” Gu continued. “Our approach is to begin with disciplined infrastructure deployment, establish operating capabilities and evaluate future expansion based on market demand, utilization and economics.”

The Company is also working with third-party infrastructure and operating partners to support the deployment and commercialization of its GPU computing capacity.

IPDN intends to continue evaluating opportunities to expand its AI infrastructure capabilities as the business develops, subject to market conditions, equipment availability, operating performance and capital resources.
