AI demand hopes lift Soitec, then safety fears and tax hit drag it down

ZenSemi 300mm BCD-on-SOI partnership Soitec will supply Power-SOI substrates to ZenSemi for high-volume 300mm BCD-on-SOI production, targeting AI datacenters, EVs and robots. This adds a new customer and supports demand for Soitec's engineered substrates, a positive for future revenue.
New partnership directly expands demand for Soitec's core products.
Q2 revenue beat and raised guidance Soitec's Q2 revenue beat estimates by nearly 22%, and it later upgraded Q2 revenue growth guidance to around 50% year-on-year, driven by Photonics-SOI demand for AI data centers. Strong results and guidance support the stock.
Earnings beat and guidance raise are key positive fundamentals for the stock.
French tax dispute settlement Soitec agreed to settle a French tax dispute, forfeiting €320 million in tax loss carry-forwards and paying up to €60 million cash in Q3 2027. This reduces future cash tax savings and is a financial negative.
Settlement has a direct negative impact on Soitec's financials.
AI slowdown fears hit chip stocks AI leaders called for slower development, triggering a sharp sell-off in chip stocks. Soitec fell 12.6% as investors worried that slower AI buildout would cut demand for its Photonics-SOI products used in AI data centers.
This is the main negative driver this period, directly hitting Soitec's AI-linked demand outlook.
€500 million ORNANE bond issue Soitec raised €500 million in convertible bonds due 2033 at a low 0.5% coupon, with conversion price at a 55% premium. Proceeds will refinance debt and fund growth, showing investor confidence in its AI-related Photonics-SOI technology.
New financing strengthens balance sheet and signals confidence, a positive for the stock.

AI Optical Demand Lifted Shijia Photons, But US Sourcing Rules and Insider Selling Weighed

AI optical demand and capacity expansion Surging AI computing demand outpaced supply, driving volume shipments of 400G/800G optical chips and ramping 1.6T. The company raised 2.8 billion yuan to expand chip capacity, supporting future growth.
This is the core positive force behind the stock's sharp rise during the quarter.
Strong financial results First-half revenue rose 50.66% and profit increased 45.3%, reflecting robust demand for the company's optical chips and supporting investor confidence.
These results confirm the company's strong operational performance and underpin the stock's gains.
US sourcing rules threaten overseas access Morgan Stanley warned that US rules may require 65% of optical module parts to be US-sourced by 2028, threatening overseas access. The stock fell over 15% on this and reports of falling 1.6T chip prices.
This regulatory risk and pricing pressure caused a significant stock decline, representing a major counterweight.
Insider selling and dilution risk Insider selling cut a major shareholder's stake, and a private placement could dilute existing holders, raising concerns about future earnings per share.
These factors added selling pressure and uncertainty, weighing on the stock.

AI demand lifts Shijia, but US content rule and insider selling weigh

AI demand drives record chip shipments Shijia said 400G and 800G optical chips are shipping in large volumes and 1.6T in small volumes, with high-end chip supply still tight. Nvidia's CPO switches entering mass production adds a new source of demand. This supports revenue growth and the stock price.
It shows the core business is growing on AI demand, the main reason the stock has been strong.
Global AI money flows to smaller suppliers Asian small-cap AI stocks, including Shijia, jumped as much as 90% in August as investors spread bets beyond big chipmakers to data center suppliers. Nearly $2.4 trillion in AI investment commitments from US tech giants supports this trend, though these stocks remain tied to the same AI spending.
It explains the broad investor appetite that has lifted Shijia's shares, while noting the risk.
Insider selling and financing plan Shareholder Hebi Investment Group sold 3.22 million shares, cutting its stake from 6.64% to 5.93%. Separately, Shijia's application for a private share sale was accepted by the Shanghai Stock Exchange. The sale adds supply of shares and signals caution; the new issuance could dilute existing holders.
It shows concrete selling pressure and potential dilution that can cap the stock price.
US content rule threatens future supply chain Morgan Stanley warned that US rules may require 65% of optical module parts to come from US suppliers, starting with 3.2T products around 2028. Shijia fell over 15% on this, plus reports of falling 1.6T chip prices. The company says it has no price-cut news, but the policy could squeeze Chinese chip makers' overseas access.
It is the main new risk that caused a sharp sell-off and could reshape the industry long term.

Shijia Photon's 2.8B yuan raise and 45% profit jump ride AI optical demand

2.8 billion yuan private placement for optical chip capacity Shijia Photon plans to raise up to 2.8 billion yuan by selling new shares, funding high-speed AWG chips, laser chips and optical interconnect parts, plus working capital. This gives the company money to expand output for AI data centers, supporting future sales and earnings growth.
It is the period's biggest company-specific capital action and directly funds growth capacity.
First-half profit up 45.3%, revenue up 50.66% First-half 2026 revenue reached 1.495 billion yuan, up 50.66%, with net profit of 315 million yuan, up 45.3%. Management said AI computing demand drove rapid data communications market growth and more orders than a year earlier, confirming the business is expanding fast.
It is the clearest evidence that AI demand is already converting into actual sales and profit.
AI computing demand outruns supply, lifting optical names Domestic AI computing demand jumped 417% year-on-year in early 2026 while supply grew only 128%, leaving high-end chips scarce and expensive. As an optical component supplier in that chain, Shijia Photon benefits from this shortage and the resulting rush to build AI infrastructure.
It explains the broad industry force pushing demand toward Shijia Photon's products.
Semiconductor supply chain rally lifts STAR-listed shares A broad semiconductor rally, helped by HBM memory demand forecasts and new AI model releases, pushed Shijia Photon up 10-12% in a single session. This reflects strong investor appetite for AI-linked chip stocks, though such sharp daily swings can reverse quickly.
It shows the market sentiment currently amplifying the stock, while noting the risk of fast reversals.
