Tower Semiconductor (TSEM) Stock Surges 14% on Oriole Networks Deal – CoinCentral

TLDR

• TSEM stock is up ~14% on Thursday and has gained over 33% since the Oriole Networks deal was announced Monday
• The deal focuses on ultra-low, deterministic-latency networking for AI architectures using Tower’s silicon photonics platform
• Tower also launched a new BCD Gen3 power management platform targeting AI data centers
• TSEM has also partnered with Salience Labs on optical circuit switching technology
• The stock is up more than 300% over the past 12 months

Tower Semiconductor (TSEM) jumped roughly 14% on Thursday, bucking a broader market decline. The move extends a rally that began earlier in the week when the company announced a partnership with Oriole Networks.

The Oriole Networks partnership centers on ultra-low, deterministic-latency networking built on Tower’s mature silicon photonics platform. The technology is aimed at AI infrastructure, where network speed and efficiency are under increasing pressure.

Oriole CEO James Regan said at the time of the announcement that AI growth is forcing the industry to rethink traditional network infrastructure. “As models grow, legacy architectures hit a hard latency wall — while Oriole’s low, deterministic latency simply steps over it,” he said.

The optical networking market that Tower is targeting could reach $80 billion by 2030, according to estimates cited alongside the deal.

New Power Platform Adds to the Story

Beyond the Oriole deal, Tower also launched its BCD Gen3 power management platform this week. The platform targets AI data centers and mobile power management, and the company says it delivers industry-leading LDMOS performance.

The launch positions Tower in the AI power management space, where demand for efficient, high-performance chips is growing.

Tower’s most recent quarterly revenue came in at roughly $1.44 billion, reflecting the company’s scale across multiple semiconductor markets.

Photonics Push with Salience Labs

Tower also has an active partnership with Salience Labs focused on optical circuit switching — moving data through light rather than electrical signals.

That work has progressed from development into pre-production, according to recent updates. The technology replaces traditional electronic switching with photonic circuits, which can handle the data demands of large AI clusters more efficiently.

Together, the Oriole and Salience partnerships give Tower a foothold in two different layers of AI networking infrastructure.

TSEM is up more than 300% over the past 12 months, making it one of the stronger performers in the semiconductor space over that period.

Thursday’s 14% gain came even as broader markets traded lower, underscoring how much investor attention the Oriole deal has drawn since Monday’s announcement.
