Tower Semiconductor Inc. reported fourth‑quarter 2025 results that surpassed Wall Street expectations, delivering record revenue of $440.21 million and diluted earnings per share of $0.70, well above the consensus of $0.68–$0.69.
Revenue grew 14% year‑over‑year and 11% quarter‑over‑quarter, driven by a 20% increase in silicon photonics sales and a 15% rise in RF infrastructure revenue. The company’s core analog and mixed‑signal segments also expanded, offsetting modest growth in legacy product lines.
Gross profit margin expanded to 26.7% from 22.4% a year earlier, reflecting higher pricing power in advanced analog nodes and a shift toward higher‑margin specialty products. Operating income rose to $55.14 million, up 30% from $42.5 million in Q4 2024, as cost controls and scale benefits offset the capital outlay for new silicon photonics capacity.
Management guided Q1 2026 revenue to $412 million, +/- 5%, a 15% year‑over‑year increase from the prior year’s $355 million. The company also announced a $270 million investment in silicon photonics equipment, bringing total spend to $920 million and positioning it to meet a 70%+ capacity reservation through 2028. CEO Russell Ellwanger said the firm plans to raise silicon photonics chip production by more than five times by year‑end 2026.
Investors reacted positively to the earnings beat, margin expansion, and forward guidance, citing the company’s strong foothold in AI‑driven data‑center markets. The company also highlighted a dispute with Intel over 300 mm wafer capacity, noting that mediation is underway and that affected customer flows are being redirected to Tower’s own fabs.
Full‑year 2025 revenue reached $1.566 billion, up 9% from $1.436 billion in 2024, while diluted EPS rose to $1.94 from $1.85. The results reinforce Tower’s strategy to shift from commodity analog to high‑margin specialty solutions, positioning it as a key supplier for AI infrastructure.
