SINGAPORE, August 21, 2025 – Rectitude Holdings Ltd. (Nasdaq: RECT; the “Company” or “Rectitude”), a Singapore-based provider of safety equipment and related industrial products, today announced the opening of a new branch at 65 Kaki Bukit Ave 1, Shun Li Industrial Park, Singapore. This strategic expansion strengthens the Company’s local presence, improves accessibility to high-demand product categories such as paint and power tools, and reinforces its position as a leading provider of safety and industrial solutions in the region.

The new branch officially opened in August 2025 and has been ramping up its operations since. The branch covers a total area of approximately 82 square meters (880 square feet) and the facility stocks in-demand products that local businesses and institutions rely on to maintain operation reliability and ensure worker safety.

Located just 10 minutes from the Central Business District, the Kaki Bukit branch is strategically positioned near key customer workplaces. It is also easily accessible via Kaki Bukit Road, ensuring access from all directions in Singapore and allowing expedited delivery capabilities. With guaranteed product availability across multiple categories, customers can easily obtain the right solutions when they need them.

We believe this new branch will help meet our growing business needs and demonstrate our commitment to providing our customers with a variety of safety equipment and related industrial products in a timely manner. As local businesses expand in Singapore, they need reliable suppliers like Rectitude to deliver quality products when and where they are required.”
