Yongding Co. expects 1H 2026 net profit attributable to parent of 500–700 mln
yuan, up 57%–120% YoY. Prior-year period included an investment gain from an
associate’s disposal of a subsidiary; no comparable item occurred in the current
period. Profits at the automotive wiring-harness and overseas engineering
segments declined YoY. The profit increase is chiefly driven by the optical
communications unit, which benefited from accelerated digital-economy rollout
and a surge in AI compute demand that lifted fiber volumes and prices, producing
sizable margin gains.
