Shares of Swiss hearing aid manufacturer Sonova Holding AG have increased by over 20% since August 2024, outperforming competitors in the sector.

This rise follows the launch of the Audeo Sphere Infinio, a device from its Phonak brand that uses artificial intelligence to enhance speech clarity in noisy environments.

The Audeo Sphere Infinio features a dual-chip system, marking a significant advancement in hearing aid technology.

Sonova’s stock now trades at 27 times expected earnings, raising concerns about whether growth can justify its high valuation.

The company is set to report its fiscal year results in May, with analysts closely watching for earnings performance.
