Onsemi, a US chipmaker specializing in power and sensing chips for electric vehicles (EVs), factories, and AI data centers, is selling two of its manufacturing sites. The company expects the moves to generate about $35 million in annual savings as it continues to streamline its operations.
Which Facilities Are Being Sold?
Onsemi plans to sell its Tarlac facility in the Philippines to Greatek Electronics, a Taiwan-based packaging and testing firm. That deal is expected to close within the next three to six months. It is also selling its Mountain Top site in Pennsylvania to Silex Microsystems, a Swedish company, with that transaction expected to close in January 2028.
The sales are part of Onsemi's broader "Fab Right" strategy, which involves keeping the plants that give the company a competitive edge and selling off the rest. By offloading these two fabs, Onsemi aims to reduce its fixed costs and focus its capital on more advanced manufacturing processes.
Why Onsemi Is Cutting Costs
Onsemi has been under pressure to improve its profitability as the semiconductor industry faces a mixed demand environment. While AI-related chips are in high demand, the market for automotive chips has softened as EV sales growth slows in some regions. The company's power management and sensing chips are used in everything from electric cars to factory automation and data centers, but the cyclical nature of the chip industry means manufacturers must constantly adjust their capacity.
By selling older or less strategic facilities, Onsemi can reduce its overhead and avoid the costs of maintaining underutilized plants. The $35 million in annual savings is a modest figure for a company with annual revenue of over $8 billion, but it signals a disciplined approach to capital allocation that investors often reward.
What This Means for Investors
For everyday investors, Onsemi's decision to sell these fabs is a sign that the company is focused on efficiency and profitability. In the chip industry, owning too many factories can be a drag on earnings when demand fluctuates. By trimming its manufacturing footprint, Onsemi is positioning itself to be more nimble and potentially more profitable over the long term.
The deals also highlight a broader trend in the semiconductor industry: companies are increasingly outsourcing manufacturing to specialized partners. Greatek, which is buying the Philippines plant, is a packaging and testing specialist, while Silex Microsystems focuses on microelectromechanical systems (MEMS). This allows Onsemi to focus on its core strengths—designing and selling chips—while leaving some production to others.
Investors should watch for updates on how Onsemi uses the proceeds from these sales. The company could reinvest the cash into research and development, pay down debt, or return it to shareholders through buybacks or dividends. Any of these moves could be positive for the stock.
Broader Market Context
Onsemi's cost-cutting comes at a time when many chipmakers are reassessing their manufacturing strategies. The industry is still dealing with the aftermath of a post-pandemic boom and bust, and companies are looking for ways to protect margins. Meanwhile, demand for AI chips continues to surge, as seen in Samsung's recent profit surge, but the automotive and industrial segments remain more uncertain.
Onsemi's focus on EVs and AI data centers puts it in a sweet spot for long-term growth, but the path to profitability requires careful management of costs. The sale of these two fabs is a step in that direction.
