Tower Semiconductor Reports 20% Revenue Growth in H1 2026, Announces Japan Expansion
Israeli chipmaker posts $158.2 million net profit for the first half as silicon photonics drives revenue gains and operational efficiency improves.
Financial Performance
Tower Semiconductor Ltd. (TSEM) reported revenue of $873.7 million for the six months ended June 30, 2026, representing a 19.6% increase from $730.2 million in the year-earlier period, according to its 6-K filing submitted August 17, 2026. The Israeli chipmaker attributed the $143.5 million revenue increase primarily to "a higher average selling price associated with a different product mix shipped," particularly more silicon photonics (SiPho) related products (6-K filing, 2026-08-17).
Net profit for the first half reached $158.2 million, compared to $85.3 million in H1 2025. Net profit attributable to the company stood at $155.8 million, up from $86.7 million year-over-year (6-K filing, 2026-08-17).
The company demonstrated significant margin expansion, with gross profit rising to $248.7 million from $153.2 million. Gross margin improved to 28.5% from 21.0% in the prior-year period, while operating profit more than doubled to $154.9 million from $72.8 million (6-K filing, 2026-08-17).
Operational Highlights
Cost of revenue increased to $625.0 million from $577.0 million, though the $48.0 million increase was proportionally smaller than the revenue gain, driving the margin improvement. Research and development expenses remained steady at 5.4% of revenue, totaling $47.1 million, while marketing, general and administrative expenses held at approximately 5.4-5.6% of revenue (6-K filing, 2026-08-17).
Cash flow from operations was robust at $686.9 million, which included a $282.6 million increase in customers' advances, net. The company invested $343.0 million in property and equipment during the period. Cash and cash equivalents stood at $231.2 million as of June 30, 2026, compared to $235.4 million at year-end 2025 (6-K filing, 2026-08-17).
Strategic Developments
Tower announced plans in July 2026 to expand its 300mm silicon photonics and silicon germanium capacity in Japan with government support. The initiative includes "repurposing the Arai facility, formerly Fab 6 (a 200mm fab that ceased its operations in 2022), for 300mm Silicon Photonics manufacturing" and potentially building an additional 300mm facility adjacent to its existing Fab 7 in Uozu. The expansion is supported by cash grants expected from Japan's Ministry of Economy, Trade and Industry (6-K filing, 2026-08-17).
The company is also restructuring its Japanese operations through a framework agreement signed March 25, 2026, with NTCJ. Under the arrangement, Tower will acquire full ownership of the Uozu fab while the Tonami facility remains with TPSCo, which will become wholly owned by NTCJ. Tower will receive a $25,000 payment from NTCJ at closing, expected April 1, 2027, subject to regulatory approvals (6-K filing, 2026-08-17).
Legal Matters
In March 2026, GlobalFoundries Inc. filed three patent infringement lawsuits against Tower in the U.S. International Trade Commission and U.S. District Court for the Western District of Texas, with an additional lawsuit filed in China. The company stated it "disputes these claims" (6-K filing, 2026-08-17).
MarginX data shows the company trading at a market capitalization of approximately $30 billion with shares last closing at $263.73. Tower is scheduled to present at the Jefferies Semiconductor conference August 25-26, 2026, and the Benchmark-StoneX Tech Conference on September 10, 2026.
