International Road Dynamics Inc. (USA) - Press Release: Quarterhill Awarded $5.3 Million Tennessee Statewide Weigh-In-Motion Contract.

• Quarterhill subsidiary IRD will install Weigh-In-Motion technology at 28 sites on various Interstate and State Routes.
• The sites will collect vehicle data related to road infrastructure protection and monitor commercial vehicle routes to improve highway safety.

Quarterhill Inc. ("Quarterhill" or the "Company") (TSX: QTRH) (OTCQX: QTRHF), a leading provider of tolling and enforcement solutions in the Intelligent Transportation System ("ITS") industry, announces that its wholly-owned subsidiary, International Road Dynamics Inc. ("IRD"), has been awarded a $5.3 million contract by the Tennessee Department of Transportation ("TDOT") to install Weigh-In-Motion ("WIM") systems at 28 sites on interstate and state routes across Tennessee. Installation is expected to be completed in May 2025. All financial information in this press release is reported in Canadian dollars.

TDOT is promoting the advancement of WIM in the state through the development of a statewide WIM program. The WIM systems will capture and record axle weights and gross vehicle weights as vehicles drive over the measurement sites at highway speeds. The sites will provide data on commercial vehicle characteristics in certain transit corridors for asset management and design improvements.

Some of the WIM sites are co-located with enforcement sites operated by the Tennessee Highway Patrol, who will integrate their commercial vehicle inspection program with the WIM data. In addition to collecting data, the WIM systems will be able to determine if trucks are overloaded so they can be routed to inspection stations for ticketing, thus cutting down on excessive highway wear-and-tear and the number of unsafe vehicles on the road. There is also the potential for future upgrades of the sites with E-screening technology to automate the evaluation of driver and trucking company safety ratings, resulting in enhanced enforcement capabilities and further improvements to highway safety.

"We are pleased to collaborate with TDOT on this project to elevate highway safety and efficiency in Tennessee," said Chuck Myers, CEO of Quarterhill. "The deployment of advanced WIM systems will provide vital data to facilitate effective enforcement, enhance asset management, and significantly improve the safety of Tennessee's highways. This project is our first major initiative in Tennessee, and we look forward to exploring opportunities to expand our footprint further in the State."
