Nanofilm Technologies International (MZH.SI) saw its stock price plummet 3.17% in Thursday's trading session, as concerns over weakening demand in the consumer electronics sector and a delay in a key customer's product upgrade weighed on investor sentiment.

The nanotechnology solutions provider faced increased downside risk due to softening demand in the consumer electronics market, according to OCBC Investment Research analyst Ada Lim. Adding to the pressure, Apple, a significant customer for Nanofilm, has reportedly postponed the upgrade of its 'Siri' digital assistant to next year, potentially impacting the expected refresh cycle that was anticipated to drive demand later this year.

Furthermore, Nanofilm's Industrial Equipment Business Unit could face challenges as clients become more cautious about capital expenditures for equipment, given the ongoing global supply chain reorganization in response to tariff developments. In light of these factors, OCBC has lowered its fair value estimate for Nanofilm to S$0.665 from S$0.735, while maintaining a hold rating on the stock.
