Subsidiary invests USD 47.9 million in Teradyne equipment

The latest corporate catalyst is a capacity investment: according to Yahoo Taiwan on September 18, 2026, subsidiary ASE Singapore Pte. Ltd. is acquiring production machinery from Teradyne Asia with a total transaction value of USD 47,923,520, equivalent to roughly TWD 1,479,121,000.

The disclosure states that the equipment purchase covers the period from January 13, 2026 to September 18, 2026 and was approved at the general manager level, underscoring management’s confidence in sustained demand for advanced test capacity, particularly in areas linked to artificial intelligence and high-performance computing packaging workloads.

Stock performance and valuation backdrop

In parallel with the equipment announcement, ASE Technology’s Taipei listing shows strong momentum: data compiled by Zonebourse on September 18, 2026 show that the Taiwan-listed shares closed at 614.00 TWD on September 17, 2026, up 145.11% year to date, while the five-day change over the latest week was a more modest minus 5.54%.

The same overview cites an average analyst target price of 707.47 TWD, implying about 15.22% upside from the latest 614.00 TWD close, and an average rating in the buy range based on 18 contributing analyses, signaling that the sell-side still sees further appreciation potential from current elevated levels.

On the United States side, the New York Stock Exchange-listed American Depositary Shares provide an additional reference: according to MarketBeat, ASE Technology’s ASX ADR closed at USD 37.86 on September 16, 2026, up 2.01% on the session and about 135.5% higher than the USD 16.08 level at the beginning of 2026, broadly mirroring the strong advance seen in the Taiwan shares.

Recent revenue trend and earnings expectations

Investors are also tracking the company’s reported revenues, which are disclosed monthly: as MarketBeat notes, ASE Technology announced its monthly net revenues on September 9, 2026 via a press release distributed through PR Newswire, which serves as one of the latest data points for gauging the strength of demand heading into the next quarterly earnings report.

The same analysis highlights that Wall Street currently expects the company’s earnings per share to grow by 61.79% over the coming year, from USD 1.23 to USD 1.99, indicating that consensus still embeds a robust expansion in profitability on top of the share price rally, although realizing that growth trajectory will depend on the successful ramp of new capacity such as the Teradyne equipment package.
