United Microelectronics (UMC) Stock Falls 6% Despite Q2 Revenue Beat

TLDR

• UMC reported Q2 2026 revenue of NT$69 billion, up 13% quarter-over-quarter and 17% year-over-year, beating estimates by ~1.8%
• June monthly sales hit NT$23.1 billion, up 23% year-over-year
• Wedbush kept a Neutral rating with a NT$80 price target; Bernstein reiterated Underperform with a $7.40 target
• Higher average selling prices (ASPs) expected in Q3 2026 following pricing increases this month
• UMC stock fell around 6% premarket as chip stocks broadly sold off

United Microelectronics (UMC) reported stronger-than-expected revenue for Q2 2026, but the stock still dropped around 6% premarket on Monday as broader chip and AI-related names sold off.

United Microelectronics Corporation, UMC

The Taiwan-based chipmaker posted June monthly sales of NT$23.12 billion, up 22.85% from a year earlier. For the full second quarter, revenue came in at NT$69 billion — up 13% quarter-over-quarter and 17% year-over-year, beating consensus estimates by roughly 1.8%.

Total revenue for the first half of 2026 reached NT$129.7 billion, an 11.28% increase year-over-year.

Wedbush kept its Neutral rating and NT$80 price target on UMC following the results. Analysts led by Matt Bryson said the sales beat — achieved even before price increases — points to genuine improvement in UMC’s underlying business.

Bryson’s team credited two main drivers: continued growth in data center demand and a smaller-than-expected pullback in consumer electronics. They also flagged that margins should benefit from improved utilization rates quarter-over-quarter.

Pricing Power Coming in Q3

UMC began raising prices on portions of its product portfolio this month. Wedbush said Q3 should benefit from higher average selling prices, and noted their current model likely doesn’t fully capture that upside — especially given the stronger Q2 revenue base the company is building from.

Bernstein took a different view. The firm reiterated an Underperform rating and kept its $7.40 price target. Bernstein pointed to UMC’s valuation as a concern — the stock is currently trading at 5.3 times trailing price-to-book, compared to a pre-cycle average of 0.8 times. The company also carries a P/E of 42.85 and a PEG ratio of 3.29.

On the technology side, UMC’s 12-nanometer development remains on schedule. PDK delivery is targeted for 2026, tape-out in 2027, and initial production in late 2027. Early applications are expected to come from digital television, Wi-Fi connectivity, and high-speed interface products.

Positive Read-Through for Peers

Wedbush said UMC’s results carry positive implications for peers in the mature foundry space, including Vanguard International Semiconductor, GlobalFoundries (GFS), and Tower Semiconductor (TSEM).

However, Bryson noted that GlobalFoundries and Tower have less exposure to more commoditized end markets, which limits how much they benefit from near-term supply/demand tailwinds.

Earlier this year, UMC beat Q1 EPS estimates by posting $0.20 against expectations of $0.13 — a 53.85% earnings surprise. That said, Q1 revenue of $1.93 billion came in slightly below the $1.96 billion forecast.

Wafer shipments for Q2 were guided to grow by a high-single-digit percentage quarter-over-quarter, supported by consumer applications and a recovery in communications.

For Q1, UMC’s average selling price guidance suggested limited like-for-like price increases in the first half of 2026 — making the now-confirmed pricing moves for the second half a potential inflection point for margins.

UMC stock fell approximately 6% in premarket trading on Monday, July 7, 2026.
