ACM Research Inc (NASDAQ:ACMR) Reports Q3 2025 Revenue Beat Amid Margin Pressures

ACM Research Inc (NASDAQ:ACMR) reported its third-quarter 2025 financial results, presenting a complex picture of robust revenue growth against a backdrop of contracting profitability. The semiconductor equipment supplier's performance elicited a muted but positive pre-market response, with shares edging approximately 0.77% higher following the announcement.

Quarterly Performance Versus Expectations

The company demonstrated significant top-line strength during the quarter, comfortably exceeding analyst revenue projections while falling short on profitability metrics.

• Revenue: $269.2 million actual versus $255.2 million estimated, representing a 32% year-over-year increase.
• Earnings Per Share (Non-GAAP): $0.36 actual versus $0.54 estimated.

This divergence highlights a quarter where strong sales growth was accompanied by substantial pressure on profit margins. The company's shipment value for the quarter was $263.1 million, a slight 0.7% increase from the same period last year, indicating that recognized revenue is beginning to outpace current deliveries.

Financial Health and Capital Position

A standout feature of the quarter was the significant strengthening of ACMR's balance sheet. The company reported a substantial increase in its cash position, with cash, cash equivalents, restricted cash, and time deposits reaching $1.10 billion as of September 30, 2025. This represents more than a doubling from the $483.9 million reported at the end of the previous quarter.

This liquidity boost stems primarily from ACM Shanghai, the company's principal operating subsidiary, which completed a private offering in September 2025. The offering raised net proceeds of approximately $623 million, providing substantial capital for future growth initiatives while reducing ACM Research's equity stake in ACM Shanghai from 81.1% to 74.6%.

Margin Compression and Operational Metrics

Despite the revenue beat, the company experienced notable margin contraction compared to the year-ago period.

• Gross Margin: 42.0% (GAAP) versus 51.4% in Q3 2024.
• Operating Margin: 10.7% (GAAP) versus 21.7% in Q3 2024.

Management attributed the gross margin figure to the lower end of the company's long-term target range of 42% to 48%, citing expected variability due to product mix and other factors. Operating expenses also increased significantly, rising 38.9% year-over-year to $84.2 million, further pressuring operating income which declined to $28.9 million from $44.2 million in the prior year period.

Business Outlook and Analyst Expectations

Looking forward, ACM provided updated full-year 2025 revenue guidance, narrowing the range to $875 million to $925 million from the previous $850 million to $950 million. This refined outlook suggests management confidence in the current trajectory.

When compared to analyst estimates, which projected full-year 2025 sales of approximately $929.9 million, the company's guidance appears cautiously optimistic, with the midpoint of $900 million sitting slightly below consensus. For the upcoming fourth quarter, analysts are forecasting revenue of approximately $273.4 million, against which the company's performance will be closely watched.

Strategic Developments and Product Innovation

During the quarter, ACM announced several significant product milestones that expand its market reach. The company shipped its first High-Throughput Ultra Lith KrF Track System to a leading Chinese logic wafer fab customer, marking its entry into lithography-adjacent applications. Additionally, ACM launched its Ultra ECDP Electrochemical Deplating tool for compound semiconductor manufacturing, demonstrating continued innovation in specialized process equipment.

CEO Dr. David Wang emphasized that "AI and global datacenter investments are demanding new innovative technology requirements for next generation semiconductor equipment," positioning the company's expanding product portfolio to capitalize on these industry trends.

Market Reaction and Investment Perspective

The slight pre-market gain suggests investors are balancing the positive revenue surprise and strengthened balance sheet against the profitability miss and margin pressures. The company's progress on its long-term $4 billion revenue target and its successful capital raise provide fundamental support, while the margin performance indicates ongoing operational challenges in a competitive semiconductor equipment market.
