A primary growth catalyst is the industry's shift to Gate-All-Around (GAA) architecture. Nova is in a "pole position" to capitalize on this transition, working with all four leading customers implementing this process. The company is on track to achieve an aggregate of $500 million in revenue from GAA by the end of 2026, with 2026 projected to be stronger than 2025, which in turn is stronger than 2024. Strong demand for GAA was observed in the first half of 2025, with stability expected in the second half.

Advanced packaging is another significant growth driver, with revenue more than doubling in 2024 to 15% of product revenue. Nova anticipates strong double-digit growth in advanced packaging revenue for 2025, expecting a higher share of total revenue compared to 2024. The memory market, particularly DRAM and High-Bandwidth Memory (HBM), also presents substantial opportunities, with HBM representing about one-third of Nova's advanced packaging business.

The service business continues its impressive growth trajectory, marking 10 consecutive quarters of revenue increase and another quarterly record in Q2 2025. Management projects 10% to 15% growth for the service business in 2025, driven by value-added services focused on productivity improvements and new application capabilities for its expanding installed base.

While China has been a significant market, its percentage contribution to total revenue is forecasted to decrease year-over-year due to higher investments in advanced nodes in other regions. However, nominal demand from China is expected to be moderately higher year-over-year for 2025, with revenues slightly skewed towards the first half. Overall, Nova expects to outperform WFE growth in 2025, historically modeling its outperformance at a ratio of 1.5 times WFE growth, which is anticipated to be higher in 2025 than in 2024.

Risks and Considerations

Despite a strong outlook, investors should consider several risks. The semiconductor industry is inherently cyclical, and while AI provides a secular tailwind, broader macroeconomic uncertainties could impact customer capital expenditure plans. The company's convertible senior notes, while providing significant capital, are unsecured obligations and are effectively junior to any secured indebtedness and structurally junior to liabilities of subsidiaries.

International trade dynamics and tariffs also present a risk. While Nova's diversified global production footprint across the U.S., Germany, and Israel helps mitigate operational impacts, tariffs could still affect gross margins. The company initially estimated a 30 to 50 basis point reduction but has since revised this to a more favorable 20 basis points due to improved visibility and localized supply chains. However, the situation remains fluid. Customer concentration, while not explicitly detailed quantitatively, is a general risk in the semiconductor equipment sector, potentially exposing Nova to shifts in a few key customers' investment strategies.
