Mizuho Initiates Tower Semiconductor at Outperform, Cites AI-Driven Optical Chip Growth

Mizuho initiated coverage of Tower Semiconductor (TSEM) with an Outperform rating and a $300 price target on Friday, citing the company's leading position in the rapidly expanding market for silicon photonics chips essential for artificial intelligence infrastructure.

The AI Optics Thesis

In a note to clients, Mizuho analyst Vijay Rakesh identified Tower as the leading and fastest-growing contract manufacturer for silicon photonics (SiPho). These specialized chips are critical for the optical connections that enable high-speed data transfer between servers in AI data centers. "Optical connectivity is key to scaling data center (DC) bandwidth and fueling the AI DC revolution for the next decade," Rakesh wrote.

Mizuho projects the market for SiPho chip manufacturing will surge from approximately $1.3 billion in 2025 to $8.5 billion by 2029, representing a compound annual growth rate (CAGR) of 60%. The firm believes Tower is positioned to outpace this market growth significantly.

Mizuho forecasts that Tower's revenue from silicon photonics will grow at a 76% CAGR to reach approximately $3.8 billion by 2029. The analyst attributes the company's market leadership to its heterogeneous packaging technology, an advantage gained from its 2008 merger with Jazz Semiconductor. Based on this technology, Mizuho estimates Tower will command over 40% of the SiPho market in 2026.

The bank's overall financial projections for Tower are also bullish, anticipating robust growth across key metrics through 2029:

• Total Revenue: Projected to grow 33% annually to $4.9 billion, ahead of the consensus estimate of $4.5 billion.
• Gross Margin: Expected to expand from about 23% to 50%.
• Earnings Per Share: Forecast to increase roughly sevenfold to $16.51.
• Free Cash Flow: Predicted to reach approximately $1.8 billion.
