TSEM

Tower Semiconductor is rapidly transforming into a silicon photonics leader, now driving nearly half its revenue from AI optical content. Q2 2026 delivered record revenue of $460M, with 55% incremental operating leverage and a robust shift toward higher-margin 300mm SiPho and SiGe wafers. Management raised the 2028 model to $3.6B in revenue and $1.2B in net profit, underpinned by strong customer prepayments and fully funded capacity expansions.

Shares of United Microelectronics (NYSE:UMC | UMC Price Prediction) are dropping 7% Tuesday afternoon to $18.22, part of a broad foundry selloff tied to renewed fears about AI capital spending.

Tower Semiconductor Ltd. (TSEM) Q2 2026 Earnings Call Transcript

Tower Semiconductor NASDAQ: TSEM reported record second-quarter 2026 revenue and profitability, citing accelerating demand for silicon photonics and related data-center connectivity products. The company also raised its 2028 financial model and detailed a two-track expansion plan in Japan intended to increase 300-millimeter manufacturing capacity for silicon photonics, silicon germanium and advanced optical packaging.

Tower Semiconductor (NASDAQ:TSEM) has reported second quarter results above Wall Street expectations, including record revenue and profitability as the chipmaker continues to benefit from demand across its key business units. The company reported adjusted earnings per share of $0.88 for the second quarter, above the analyst consensus of $0.67.

Tower Semiconductor offers robust fundamentals, pristine balance sheet, and strong cash flows, but current valuation already prices in an aggressive 2028 outlook. TSEM's AI-driven silicon photonics expansion in Japan, supported by a $1bn government grant, underpins a near-doubling of revenue and profit targets by 2028. Despite operational strength and strategic positioning, TSEM trades at premium multiples—forward P/E of 66.53 and EV/Sales of 12.40—making valuation the central concern.

When artificial intelligence (AI) models scale, they inevitably run into a hard physical limit. Modern data centers currently rely on traditional copper wiring to connect servers and graphics processing units.

Tower Semiconductor (NASDAQ:TSEM) shares rose 13% on Tuesday after the company announced a strategic expansion of its silicon photonics, silicon germanium (SiGe), and advanced packaging capabilities in Japan with support from the Japanese government. The semiconductor foundry said the dual-track expansion plan is designed to significantly increase manufacturing capacity and support growing customer demand, particularly from artificial intelligence and data center applications requiring next-generation optical connectivity.
