ChipMOS's sales reached NT$2,538m in June, up 6.5% MoM and 37% YoY, for Q226 +886-28-722 7306

sales of NT$7,383m (6.5% QoQ growth), broadly in line with the UBS/consensus

GM to rise 3.4ppt QoQ to 17.2% on better pricing and a more favourable mix, with EPS

at NT$1.03 (+42% QoQ). We expect Q326 sales to grow 8% QoQ on driver IC

restocking and better DDR4/5 volume, while GM may improve another 0.7ppt QoQ to

17.9%, on greater scale, offset by higher electricity cost. We expect Q426 sales to stay

flattish, with steady memory demand, offset by a seasonal driver IC slowdown.

Valuation: Raise price target to NT$156; reiterate Buy rating

Our PT of NT$156 is based on 23x average 2027-28E PE (vs. a 5-27x historical

normalized range), in line with the average of OSAT peers. We do not believe its
