OMS Energy Technologies Inc.’s Indonesian Subsidiary Secures API Spec 11D1 Certification, Reinforcing Its Industry Leadership

Broadens Product Range with In-House Developed Certified Parts, Unlocking Fresh Revenue Streams Across Asia Pacific

SINGAPORE, Nov. 26, 2025 — OMS Energy Technologies Inc. (“OMS” or the “Company”) (NASDAQ: OMSE), a manufacturer focused on growth in surface wellhead systems (“SWS”) and oil country tubular goods (“OCTG”) for the oil and gas sector, today revealed that its fully-owned subsidiary, PT OMS Oilfield Services (“OMS Indonesia”), has successfully obtained the American Petroleum Institute’s API Spec 11D1 certification. This achievement allows OMS Indonesia to broaden its product catalog with certified, proprietary-developed, and locally manufactured packers, essential components for petroleum and natural gas extraction. This significant accomplishment reinforces OMS’s dedication to upholding leading industry benchmarks and boosts its capacity to secure new contracts in challenging oilfield environments.

The API Spec 11D1 standard outlines criteria for the design, production, testing, and quality assurance of packers and bridge plugs, guaranteeing that equipment can withstand demanding conditions and thereby fostering increased reliance and assurance among operators and service providers. Following the acquisition of API Spec 11D1 certification, OMS Indonesia will expand its existing range of API-6A-certified surface wellheads and Christmas trees by incorporating comprehensive product design, qualification, and manufacturing of retrievable mechanical and hydraulic packers. These components are designed for effortless integration with both OMS’s surface wellhead systems and equipment from other producers, providing clients with adaptable, high-performance options and generating varied income streams.

We intend to maintain our focus on attaining the most rigorous standards for quality and safety, thereby solidifying OMS’s standing as a reliable collaborator for prominent energy producers throughout the Asia Pacific region.”

The API Spec 11D1 certification serves not only to bolster OMS’s technical prominence but also strategically positions the company for expedited expansion within both national and global markets. As OMS continues to enlarge its international presence, this certification will be instrumental in fostering client trust and forging new strategic alliances across the globe.
