Recent figures define the baseline

Nanosonics supplies automated technology used in the cleaning and disinfection of medical instruments, with its installed base and recurring consumables providing the key operating context for the stock. The latest market evidence in the current reporting window is the share move to AUD 3.05 and the 4.45 percent daily gain recorded on September 21, 2026.

The company remains a health care equipment name on the Australian market, so peer performance provides a more useful near-term comparison than broad index direction.
