Quarterhill Introduces TOPAS-Registered Intersection Solution in United Kingdom

Company expanding into the UK traffic signal market with the new TOPAS 2505B-registered version of its TMB-13X product

TORONTO, Sept. 24, 2026 /PRNewswire/ -- Quarterhill Inc. ("Quarterhill" or the "Company") (TSX: QTRH) (OTCQX: QTRHF) – a leading technology innovator providing next-generation, AI-driven Intelligent Transportation System ("ITS") solutions – today announced its proprietary, multilane intersection radar "TMB-13X" has achieved TOPAS 2505B registration, a requirement for any traffic signal detection technology deployed in the UK. This accomplishment enables Quarterhill to provide UK transport authorities with a reliable, easy-to-use and cost-efficient product; enabling safer and more efficient roads with industry-leading deployment times.

Designed for complex, multilane intersections, the TMB-13X provides traffic authorities with an above-ground alternative to traditional inductive loop detection, helping reduce the roadwork, installation costs and traffic disruption associated with in-road sensors. The product can monitor vehicles and cyclists across multiple lanes; and uses up to nine configurable virtual detection loops based on speed, direction of travel, movement and presence. It also features a compact four-meter blind zone and an intuitive browser-based configuration interface accessible via Wi-Fi to enable faster deployment and simpler ongoing maintenance.

The United Kingdom is one of the most significant markets for traffic signal detection technologies in Europe. Transport for London alone operates approximately 6,400 traffic signal sites, including approximately 4,000 signalized junctions and 1,500 pedestrian crossings, supported by more than 16,000 traffic detectors.¹ This registration builds on Quarterhill's existing presence in the UK market, extending the Company's ITS technologies into intersection detection alongside its established UK operations. With TOPAS approval now secured, Quarterhill can now offer the TMB-13X product to UK traffic signal controller manufacturers, system integrators and transport authorities across the country.

"Bringing together more than 30 years of radar-based product development in a solution designed to address the complexities of modern intersections, the TMB-13X reflects our continued focus on technologies that make transportation infrastructure safer and more efficient," said Donna Bergan, Vice President of Intelligent Transportation Systems at Quarterhill. "Securing TOPAS registration means we can extend these capabilities to customers across the UK, providing traffic engineers with a flexible solution that can simplify installation and ongoing maintenance, while minimizing disruption to road users."

The TOPAS registration reflects Quarterhill's broader approach to international growth: adapting its ITS technologies to meet the specific regulatory and technical standards of each market it enters. Quarterhill's Smart Transportation and Enforcement solutions are currently deployed across North America, Europe, Middle East and Asia-Pacific.

This milestone adds to continued momentum across Quarterhill's ITS business. In August 2026, the Company reported its strongest quarter of profitability in more than three years. Quarterhill is also progressing toward the expected fourth-quarter 2026 closing of its previously announced acquisition of Conduent's tolling solutions business, which is expected to significantly expand the Company's scale and further advance its strategy to build a larger, more focused ITS platform.

The TOPAS-registered TMB-13X is now available for order.
