GN AUDIO A/S

GN Audio A/S, despite its core business in audio, shows a surprising and rapid emergence in visual communication technologies, with Pictorial / Video Communications growing by 75.0% in 2024 and Image Processing by 100.0% in the same year, indicating a strategic shift towards integrated audio-visual solutions. While Loudspeakers & Microphones remains its largest category at 36.8% of its portfolio, the significant year-over-year declines in patenting across most categories in 2025 and so far in 2026 suggest a potential re-evaluation or consolidation of its R&D focus.
