Despite facing some challenges with fab utilization and increased lease costs, the overall sentiment was positive, buoyed by strategic investments and a forecasted record revenue for the fourth quarter of 2025.
Strong Revenue and Profit Growth
Tower Semiconductor reported impressive financial results for the third quarter of 2025, with revenue reaching $396 million. This marks a 7% increase year-over-year and a 6% rise quarter-over-quarter. The net profit for the quarter was $54 million, which is a 15% increase from the previous quarter, underscoring the company’s strong financial performance.
Forecasted Record Q4 Revenue
The company has set its sights on achieving a record revenue of $440 million for the fourth quarter, with a margin of plus or minus 5%. This guidance reflects Tower Semiconductor’s commitment to maintaining quarter-over-quarter growth throughout the year.
RF Infrastructure and Silicon Photonics Growth
RF infrastructure has been a significant growth area for Tower Semiconductor, with revenue increasing from $67 million in Q3 2024 to $107 million in Q3 2025. This segment now accounts for 27% of the company’s revenue. Additionally, the silicon photonics segment experienced a remarkable 70% year-over-year growth, reaching $52 million in Q3 2025.
Increased Capacity and Strategic Investments
To support its growth trajectory, Tower Semiconductor announced an additional $300 million investment in expanding its silicon photonics and silicon germanium capacities. This builds on a previous investment of $350 million, highlighting the company’s strategic focus on high-margin platforms.
Fab Utilization Challenges
Despite the positive growth figures, Tower Semiconductor faces challenges with underutilization in some of its fabs. Fab 9 operated at 60% utilization, and Fab 2 in Israel at about 65%, indicating room for improvement in operational efficiency.
Newport Beach Fab Lease Costs
The extension of the Newport Beach fab lease has financial implications, requiring an upfront payment of $105 million and adding $6 million per quarter to the cost of goods sold (COGS). This will impact the company’s quarterly costs moving forward.
Forward-Looking Guidance
Looking ahead, Tower Semiconductor projects a record revenue of $440 million for the fourth quarter, continuing its trend of quarter-over-quarter growth. The company is also focusing on expanding its high-margin silicon photonics and silicon germanium platforms, with a goal of achieving a Q4 ’25 annualized revenue run rate exceeding $320 million.
In summary, Tower Semiconductor’s earnings call conveyed a positive outlook, driven by strong financial performance and strategic investments in growth areas like RF infrastructure and silicon photonics. While challenges such as fab utilization and increased lease costs exist, the company’s forward-looking guidance suggests continued growth and profitability.
