Axcelis Technologies, Inc. (NASDAQ: ACLS) reported fourth‑quarter and full‑year 2025 results on February 17, 2026, with revenue of $238.3 million, a GAAP gross margin of 47.0 % and a GAAP operating margin of 15.2 %. Net income was $34.3 million, giving a diluted GAAP EPS of $1.10. The company’s non‑GAAP figures were higher, with a gross margin of 47.3 % and an operating margin of 21.1 %. The fourth‑quarter revenue was down 5.6 % from $252.4 million in Q4 2024, and the GAAP diluted EPS fell 28 % from $1.54 in the prior year, reflecting weaker demand and lower operating leverage.
The results were driven by a record quarter in the Customer Solutions & Innovations (CS&I) aftermarket segment, which generated $82 million in revenue—$10 million above the $70 million originally reported. Systems revenue was $156 million. The CS&I record was attributed to a strong installed base and a focus on upgrades and service contracts, as CEO Russell Low noted: "We achieved another record quarter of CS&I revenue, reflecting the strength of our growing installed base and our strategic focus on driving upgrades and service contracts." The strong mix helped lift the gross margin to 47.3 % non‑GAAP, while the lower volume and a higher proportion of memory‑system sales contributed to the 21.1 % non‑GAAP operating margin.
Axcelis beat consensus estimates on both revenue and earnings. Revenue of $238.3 million surpassed the $215.3 million consensus by $23.0 million, a 10.7 % beat. GAAP diluted EPS of $1.10 exceeded the $1.12 estimate by $0.02, a modest 1.8 % beat, while non‑GAAP diluted EPS of $1.49 beat the $1.12 estimate by $0.37, a 33 % beat. The earnings beat was largely driven by the CS&I record and the favorable mix of high‑margin memory and silicon‑carbide implantation sales, which offset weaker demand in power and general mature markets.
For the first quarter of 2026, Axcelis guided to revenue of approximately $195 million, GAAP EPS of $0.38 and non‑GAAP EPS of $0.71. The guidance is below analyst consensus of $204.1–$207.2 million for revenue and $0.90–$0.99 for EPS, reflecting management’s caution amid a mixed‑demand environment. CFO Jamie Coogan said: "We anticipate overall revenue to be relatively flat compared to 2025 levels. We expect revenue to be second half weighted. We anticipate growth in our memory market to offset a decline in our power and general mature markets." The sequential decline in Q1 gross margin is expected to be around 41 % due to a less favorable mix, lower volume, a higher proportion of memory systems, and a decline in CS&I upgrades.
Axcelis also highlighted its strategic focus on silicon‑carbide implantation for electric‑vehicle and data‑center customers, and the launch of the Purion H6 high‑current ion implanter. The company’s pending merger with Veeco Instruments, expected to close in the second half of 2026, is positioned to enhance its competitive standing in AI, electrification and next‑generation device architectures. Management expressed confidence in the combined company’s prospects: "We continue working toward closing our pending merger with Veeco and remain confident in the compelling prospects and potential of the combined company."
The full‑year 2025 revenue was $839.0 million, down 17 % from $1,017.9 million in 2024, and full‑year GAAP diluted EPS was $3.80, down from $6.15 in 2024. The decline reflects weaker demand in power and general mature markets, while the memory segment’s growth helped mitigate the impact. China accounted for 42 % of full‑year revenue, but its share fell to 32 % in Q4, indicating a shift as customers digest prior investments in mature‑node capacity.
Market reaction to the earnings release was negative, with the stock falling 14.8 % after the close. The drop was driven by the Q1 2026 guidance, which fell short of analyst expectations for both revenue and EPS, outweighing the strong Q4 earnings beat.
Axcelis’s financial health remains robust, with strong revenue growth, high margins, and a conservative leverage profile. The company generated more than $100 million of free cash flow in 2025 and returned over $120 million to shareholders through dividends and share repurchases.
