ACLS Q1 2025: 0.8x Book-to-Bill Fuels Strong Order Growth
- Robust order momentum: The Q&A discussion highlighted a 0.8x book-to-bill ratio in Q1—significantly higher than the historical average of 0.5x—indicating strong order intake, particularly from the general mature and power segments, which bodes well for future revenue trends.
- Diversified international footprint: Comments in the Q&A pointed to sequential improvements in U.S. revenue and encouraging progress in markets like Korea and Japan. This diversification reduces reliance on China and supports growth through exposure to multiple regional dynamics.
- Secular growth driven by technology transitions: The executives emphasized ongoing transitions from 150- to 200-millimeter tools, along with a shift from planar to trench and superjunction technologies. This evolution increases implant complexity and capital intensity, positioning the company to benefit from long-term semiconductor trends.
- China revenue exposure is uncertain: Executives indicated that while China revenue was 37% in Q1, they expect it to drop year‑over‑year, with potential swings quarter‑to‑quarter. This uncertainty in the mix and reliance on a volatile market could pressure overall revenue growth.
- Reliance on a narrow memory segment: Although DRAM orders have increased, NAND remains muted—with recovery largely limited to DRAM. This concentration raises concerns about the breadth and sustainability of the memory business.
- Tariff and macroeconomic uncertainty: While the company has plans to mitigate tariff effects, the responses highlight that any upside from easing tariffs would be limited and that ongoing geopolitical pressures continue to pose risks to margins and demand.
| Metric | YoY Change | Reason |
|---|---|---|
Total Revenue | –24% ( ) | Q1 2025 total revenue dropped to $192.6 million from $252.4 million in Q1 2024 mainly due to lower system sales, which significantly reduced product revenue compared with the previous period. ( ) |
Product Revenue | –25% ( ) | Product revenue fell to $182.8 million from $243.4 million YoY, driven by a sharp decline in system sales, reflecting subdued capital spending relative to the previous quarter. ( ) |
Services Revenue | +9% ( ) | Services revenue increased to $9.74 million YoY, likely as customers relied more on maintenance and service contracts amid a drop in new system purchases, marking a shift in the revenue mix compared with Q1 2024. ( ) |
Operating Income | –48% ( ) | Operating income dropped to $29.2 million from $56.5 million, as the decline in overall revenue reduced gross profit and exposed fixed cost pressures, worsening operational leverage compared with the previous period. ( ) |
Net Income | –44% ( ) | With net income falling to $28.6 million from $51.6 million, the bottom line was strongly impacted by lower operating performance and revenue declines, consistent with the changes seen in operating income. ( ) |
Asia Pacific Revenue | –28% ( ) | Asia Pacific revenue fell to $134.4 million from $188.2 million, indicating a significant regional slowdown possibly due to softer market demand and economic pressures compared to the previous period. ( ) |
North America Revenue | –11% ( ) | North America revenue declined to $40.5 million from $45.5 million, reflecting a moderate drop in customer demand relative to Q1 2024. ( ) |
Europe Revenue | –6% ( ) | Europe revenue saw a modest decrease to $17.6 million, down roughly 6% YoY, suggesting that while the region experienced a downturn, the impact was less severe than in other regions. ( ) |
Cash and Cash Equivalents | +50% ( ) | Cash and cash equivalents surged to $184.0 million from $123.5 million by Q1 2025, primarily driven by the sale of held-to-maturity securities and subsequent reinvestment, which bolstered liquidity amid overall revenue declines. ( ) |

Margin Dynamics
Q: What drove Q1 margin performance?
A: Management explained that Q1 margins were boosted by a favorable mix—about 600 basis points from deferred revenue adjustments and high-margin spare sales—but they expect a 400 basis point softness in Q2 due to lower volumes and mix changes, with tariffs having only a small impact. -
China Revenue
Q: How did China revenue perform and what's the outlook?
A: They reported that China revenue dropped to 37% of total system sales in Q1, and while a sequential rebound is anticipated in Q2, overall China’s contribution for 2025 is expected to be lower compared to 2024, without further geographic breakdown. -
Order Book & Backlog
Q: How strong is the order book and what does the backlog indicate?
A: Management noted robust bookings with a 0.8x book-to-bill ratio and a sizeable backlog primarily reflecting general mature and power segments, though detailed geographic mix—especially for China—was not disclosed. -
Tariff Impact
Q: What is the margin effect of tariffs?
A: They emphasized that through diversification across a global supplier and manufacturing base, the tariff impact has been largely mitigated, resulting in a relatively small net effect on margins. -
Technology Transitions
Q: How are shifts from 150mm to 200mm and trench transitions progressing?
A: Management explained that moving from 150mm to 200mm formats and transitioning from planar to trench/superjunction technology enable higher-energy implants, thereby supporting future growth and leveraging their core strengths, though specific percentages weren’t provided. -
Inorganic Growth
Q: Are there plans for acquisitions?
A: They are keeping the option open for bolt-on acquisitions to complement their core technology and global operations, but no specific targets or transformative deals have been detailed. -
Memory Business
Q: How is the memory segment performing?
A: The growth in the memory segment is driven largely by DRAM orders, showing some modest pickup, while NAND activity remains subdued due to customers focusing on vertical capacity expansions. -
OpEx Guidance
Q: Why keep operating expenses flat amid lower revenue?
A: Management is sustaining flat OpEx as a strategic investment—in R&D and operational readiness—to position the business for a market turnaround, despite a potential decline in revenue. -
Japan Presence
Q: What progress is seen in Japan?
A: They reported positive developments in Japan with new placements in silicon carbide and general mature systems, anticipating that Japan’s revenue share will gradually increase as orders pick up. -
Image Sensor & NAND Activity
Q: How are image sensor and NAND orders behaving?
A: Image sensor sales are now embedded within general mature revenue, while NAND activity remains quiet because customers need more new wafer starts, keeping quoting activity low.
