Datronix (HKG:0889) entered into a new three-year master supply agreement with Datatronics Romoland to continue supplying magnetic components through December 2028, according to an Oct. 10 Hong Kong bourse filing.

Shares of the firm were up over 1% in Monday's late-morning trade.

The deal renews an existing agreement expiring at the end of this year.

The proposed annual caps are set at HK$40 million, HK$44 million, and HK$48 million for 2026, 2027, and 2028, respectively, the filing said.

Datronix said the renewal secures a stable income stream from a long-term US customer in the medical and aviation magnetics market, noting that products supplied under this agreement yield higher profit margins than other sales.
