ACMR vs KLIC: Battle of the Semiconductor Equipment Stocks

ACM Research (NASDAQ:ACMR) and Kulicke & Soffa (NASDAQ:KLIC) both make semiconductor tools, but their latest earnings told very different stories. ACM posted record annual revenue while margins collapsed. Kulicke beat estimates and guided higher. Same sector, very different momentum.

Record Revenue, Shrinking Margins vs. A Clean Turnaround Quarter

ACM Research closed Q4 2025 with $244.43M in revenue, a 9.4% YoY gain that beat estimates. But the headline hid a bruising margin story. Gross margin fell to 40.9% from 49.6% a year earlier, squeezed by product mix shifts toward lower-margin semi-critical cleaning tools, competitive pricing pressure, and inventory charges. Non-GAAP EPS came in at $0.25, missing the $0.53 consensus by a wide margin. For the full year, ACM delivered $901.31M in revenue, up 15.2%, a genuine record, but EPS of $1.61 still missed estimates.

Kulicke’s Q1 FY2026 looked cleaner. Revenue hit $199.63M, up 20.2% YoY, beating the $190M estimate. Non-GAAP EPS of $0.44 crushed the $0.33 consensus. Gross margin held at 49.6%. After restructuring that included exiting its Electronics Assembly equipment business and absorbing roughly $86.6M in charges, the recovery trajectory is unmistakable.

China Concentration vs. Portfolio Discipline

ACM’s business remains heavily anchored in China, creating real exposure to export controls and trade policy shifts. CEO David Wang is pushing to diversify, pointing to the Singapore foundry deployment and an Oregon facility expected to open in the second half of 2026. Wang framed the ambition directly: “We believe ACM has the customers, the products, the capacity and the capital to execute on our global business plan and we remain committed to our long-term target of $4 billion in revenue.” That target is real, but the path runs through geopolitical uncertainty.

Kulicke shed its Electronics Assembly business entirely and doubled down on Power Semiconductor, Advanced Dispense, and Advanced Packaging technologies. Interim CEO Lester Wong described the logic: “Our prior investments in Power Semiconductor, Advanced Dispense, and Advanced Packaging, both Vertical Wire and Fluxless Thermo-Compression, strategically position us to further expand our market access over the long-term.” The restructuring cost them short-term, but Q1 FY2026 shows the cleaner model is working.

What to Watch Next

For ACM, the critical question is whether gross margins can recover toward 49.6%. The $1.08B to $1.175B FY2026 guidance implies strong growth, but if mix stays unfavorable, the bottom line won’t follow. Kulicke’s Q2 FY2026 guidance of approximately $230M in revenue and $0.67 non-GAAP EPS suggests the acceleration isn’t done.

ACM’s analyst target of $70.50 sits well above its current $46.92, and six analysts rate it buy or strong buy. But that EPS miss is hard to dismiss, and China risk is structural, not cyclical. Kulicke trades near its $66.67 analyst target at $66.15, and the earnings trajectory and margin profile are more predictable. Kulicke also pays a dividend, while ACM’s growth story carries higher execution risk tied to geographic concentration.
