Spotlight Stock: Yisheng's Order Visibility Rises as It Targets Niche Applications in Aerospace, Soaring at Open

Yisheng (5291-TW), a PCB manufacturer that has joined Taiwan's semiconductor national team, achieved a record revenue of NT$185 million in July 2026. Current order visibility has improved to a three-month horizon, and with the new Phase II plant now operational, overall monthly production capacity is expected to increase to 1.5 times the original level. As the company expands into applications such as AI, low Earth orbit satellites, and aerospace, its stock opened sharply higher in early trading, briefly hitting the daily limit at NT$60.8, with volume exceeding 1,300 shares.

Yisheng's after-tax net profit for the first half of 2026 was NT$36.67 million, with earnings per share (EPS) at NT$0.92.

Yisheng still has room for further growth, with key factors including the order mix in the second half, raw material supply, and whether order volume remains sufficient. Rising raw material prices in the first half of 2026 increased production costs, and for the majority of products—70% to 80%—these cost increases are expected to be reflected in shipment prices by the third quarter.

Yisheng's investment in expanding its Guishan Phase II facility is approximately NT$500 million, primarily aimed at expanding production lines and upgrading manufacturing processes to comprehensively enhance its high-end PCB production capabilities. The new plant will introduce advanced production equipment, automated material handling, and digitalized process management to further expand capacity for niche PCBs such as high-layer-count, high-precision, high-frequency/high-speed, and heavy-copper boards. According to Jian Rongkun, the expansion will help further increase the proportion of Yisheng's high-value-added products, expand revenue scale, and establish a solid foundation for gross profit structure.
