Silentium Ltd. develops software-based Active Acoustics solutions designed to manage in-cabin sound in vehicles. The Company’s technology reduces unwanted noise, enhances desired audio cues, and enables personalized, configurable acoustic experiences, thereby supporting improved comfort, safety, and perceived quality in modern vehicles.

Silentium’s solutions are primarily deployed in the automotive market and are designed to integrate with vehicle computing, control, and audio systems. Rather than relying on heavy mechanical insulation or dedicated hardware modules, the Company’s software leverages existing microphones, speakers, processors, and electronic control units (ECUs) to monitor, estimate, and dynamically shape acoustic fields inside the vehicle cabin. This software-centric approach aligns with the automotive industry’s transition toward software-defined vehicle architectures, in which functionality is increasingly implemented and updated through software rather than fixed hardware components.

The Company works directly with automotive original equipment manufacturers that design, engineer and produce vehicles under their own brands (“Auto OEMs”), companies that supply complete systems and modules directly to Auto OEMs (“Tier-1 suppliers”), and semiconductor and digital signal processing partners to support adoption across vehicle platforms and production programs. Silentium’s technology is typically embedded at the vehicle platform level and remains integrated throughout the production lifecycle of the model, which generally ranges from four to seven years.

Silentium is a development-stage company. To date, the Company’s commercialized products consist exclusively of road noise and engine noise cancellation solutions. As of September 30, 2026, Silentium’s technology was deployed in approximately 1.8 million vehicles across 26 models of vehicles (each model as defined by the applicable Auto OEM and collectively, “vehicle models”) and five Auto OEMs (see “Business — Our Key Performance Indicators”). As additional vehicles enter production, the number of vehicles incorporating our software increases, generating royalties over the production life of each multi-year vehicle production cycle for which the Company provides development services and per-unit royalty-bearing software licenses (“vehicle program”), and enhancing revenue visibility.

Revenues are derived from non-recurring engineering (“NRE”) fees generated during the software development and integration phases of specific vehicle programs, followed by per-vehicle royalties that become payable upon the commencement of serial production. Our royalty revenue depends on the Auto OEM’s production volumes over the multi-year lifespan of the vehicle program. The Company also integrates its algorithms into existing infotainment and audio system architectures through Tier-1 suppliers and semiconductor manufacturers, which can facilitate deployment across additional vehicle platforms.

Silentium operates globally, with its headquarters and principal research and development activities based in Israel and additional engineering, technical support and business development presence in North America, Europe and Asia. This enables close collaboration with Auto OEMs and Tier-1 suppliers across major automotive production hubs and supports ongoing program execution, calibration, and validation activities.

While automotive remains the Company’s core focus, its Active Acoustic Management (AAM) technology may also be applicable to other transportation and mobility use cases, including rail, commercial vehicles and heavy machinery, where noise reduction, communication clarity and acoustic zoning are relevant.
