Shares of semiconductor equipment makers Axcelis Technologies and Veeco Instruments moved in opposite directions on Wednesday after the companies announced plans to merge in an all-stock transaction valued at $4.4 billion.
The deal, which is expected to close in the second half of 2026, will create the fourth-largest US wafer fabrication equipment company with a total addressable market of more than $5 billion.
Market reaction and transaction details
In early afternoon trading, Veeco stock jumped 7.5% to $32.72 while Axcelis shares fell 3.4% to $94.27.
The contrasting moves highlight the market’s mixed reaction to the proposed deal.
Under the terms of the agreement, Veeco shareholders will receive 0.3575 Axcelis shares for each Veeco share they own.
Upon completion, Axcelis investors will control 58% of the combined entity, with Veeco shareholders owning the remaining 42%.
The merger is structured as an all-stock transaction, and the combined enterprise value is pegged at $4.4 billion based on the most recent closing prices of both companies.
As of the last close, Axcelis had a market capitalization of $3.07 billion, while Veeco was valued at $1.83 billion, according to LSEG data.
Year-to-date, Axcelis shares had gained nearly 34% while Veeco shares were up about 21%.
Strategic rationale and growth prospects
Executives said the combination will expand product offerings, increase profitability, and add scale that strengthens Axcelis’s competitive position.
The companies expect the merger to generate $35 million in annual cost savings within two years of closing.
DA Davidson analyst Thomas Diffely noted in a report that the deal increases the combined company’s exposure to several high-growth markets, including artificial intelligence, power devices, and electrification.
He added that the move expands the addressable market to approximately $5 billion and positions Axcelis as both a stronger competitor and a potentially attractive target for larger industry players such as Lam Research.
Russell Low, Chief Executive Officer of Axcelis, and James Coogan, the company’s Chief Financial Officer, will retain their roles following the merger.
The companies emphasized that the integration will create a more efficient business with broader capabilities across the semiconductor equipment sector.
Industry context and outlook
The merger comes at a time of heightened demand for semiconductor equipment, driven by the growth of AI applications, electrification trends, and the expansion of power devices.
The semiconductor industry has been consolidating in recent years as firms seek greater scale to weather cyclical downturns and capitalize on structural growth opportunities.
While management remains optimistic about the long-term benefits, near-term investor reaction has been cautious.
Axcelis shareholders appear concerned about dilution and integration risks, even as Veeco investors welcomed the premium embedded in the exchange ratio.
If approved by regulators and shareholders, the transaction will reshape the US semiconductor equipment landscape, with the combined company emerging as a top-tier competitor.
Despite short-term market volatility, both firms see the merger as a strategic step to accelerate growth, capture efficiencies, and position themselves for rising demand in key technology markets.
