Unimicron reported Q3 2026 EPS of 6.32 on 2026-10-27, beating the 4.30 consensus by 2.02 (+47.0%).

Print-day reaction was −2.3%, as the stock opened higher but sold off to close below the prior session's level despite a substantial EPS beat. The overnight gap to the T+1 open recovered sharply, adding +8.0%, suggesting initial sellers may have been premature. Over trading days 1–3, however, price drifted −10.1% from the T+1 open through the T+3 close, fully reversing the overnight rebound and then some. With a total 3-day return of −8.8% and no valid benchmark CAR available, the PEAD verdict is none — the conflicting signals and drift reversal do not establish a clean directional read; the holding window nominally extends to 2027-01-22.
