Synopsys Shares Plunge 35% on China Woes, Erasing 2025 Gains

/in /tarafından

Synopsys shares tumbled nearly 35% on Wednesday, putting the chip design software giant on track for its worst single-day drop on record and wiping out gains accumulated in 2025. The decline followed disappointing earnings and fresh concerns about its business in China, a key semiconductor market under tightening U.S. export restrictions.

The company reported Q3 revenue of $1.74 billion, missing analyst estimates, with weakness in its IP segment. CEO Sassine Ghazi blamed U.S. export curbs — which blocked sales of chip design software to China for more than a month — and setbacks at a “major foundry customer.” Although restrictions were lifted in July, analysts said Chinese customer confidence has eroded, leaving demand subdued.

Synopsys generates more than 10% of industry revenue from China, but geopolitical tensions have made that stream increasingly fragile. Shares of rival Cadence Design Systems also dropped nearly 7% in sympathy.

While Ghazi did not identify the foundry customer, analysts pointed to Intel, which has dramatically scaled back its 18A chip manufacturing technology and broader foundry ambitions. J.P. Morgan suggested Synopsys had dedicated significant IP resources to Intel’s program, only to see its potential curtailed.

The downturn comes as Synopsys completes its $35 billion acquisition of Ansys, a move aimed at diversifying its engineering software portfolio. However, the company also announced it will cut 10% of its workforce by 2026 as part of a strategic review.

With trade restrictions clouding its China outlook and reliance on slowing customers like Intel, Synopsys faces mounting pressure to stabilize its core business even as it integrates Ansys.

U.S. Warns of Hidden Radios in Solar-Powered Highway Infrastructure

/in /tarafından

U.S. transportation officials have issued a security advisory warning that solar-powered highway equipment — including electric vehicle chargers, weather stations, and traffic cameras — may contain undocumented cellular radios and other rogue devices hidden inside imported inverters and battery systems.

The advisory, circulated by the Federal Highway Administration (FHWA) on August 20 and reviewed by Reuters, follows discoveries of undocumented communications components in foreign-manufactured power inverters and battery management systems (BMS). While the note did not name a country of origin, many inverters are produced in China, and the warning aligns with rising U.S. scrutiny of Chinese technology in critical infrastructure.

Officials fear such hidden radios could allow remote tampering, enabling disruptions ranging from synchronized outages to the manipulation of roadside systems essential for autonomous vehicle operations. Anomadarshi Barua, a George Mason University researcher, said compromised inverters could be exploited to trigger power surges or send malicious commands, “creating a lot of havoc.”

Earlier this year, U.S. energy officials raised alarms after rogue communications hardware was found in Chinese-made inverters and batteries. Denmark’s grid operators also reported unexplained electronic components in imported energy equipment.

The FHWA memo urged transportation authorities to inventory inverters, conduct spectrum scans for unauthorized signals, remove undocumented radios, and ensure network segmentation to limit exposure.

China’s Embassy in Washington rejected the warnings, denouncing what it called the “distortion and smear of China’s achievements in energy infrastructure.”

The warning adds to broader U.S. measures targeting Chinese technology. Washington has already moved to ban most Chinese cars and trucks from the U.S. market by late 2026 over concerns that vehicle software and sensors could be used for data collection or surveillance.

Apple’s iPhone Event May Lack Spark, but Rumored Slim ‘iPhone Air’ Could Drive Upgrades

/in /tarafından

Apple is set to unveil its latest iPhone lineup on Tuesday, but analysts warn the launch could feel underwhelming compared with rivals’ rapid AI integration. The highlight may be the rumored “iPhone Air”, a slimmer model designed to echo the sleekness of Apple’s MacBook Air.

The thinner device would require Apple to solve battery and camera design challenges while fitting into a price band between the base iPhone 17 and Pro models. Analysts say this new form factor could entice iPhone 14–16 users to upgrade, offering Apple its first meaningful design shift in years.

Some see the “Air” as a stepping stone toward foldable iPhones and a more advanced Siri, though foldables are not expected until next year. Competitors like Samsung and Google already have folding models, but they remain a niche category at less than 2% of global sales. Apple faces added pressure in China, where foldables are popular and its market share has slipped.

Pricing remains a sensitive issue amid Trump’s tariff policies. Apple may quietly push margins higher through storage-based price increases, avoiding direct price hikes that could trigger political backlash, analysts say.

On the AI front, Apple has lagged rivals. Plans to revamp Siri were delayed by engineering hurdles, forcing the company to lean on OpenAI’s ChatGPT integration. Apple is also in early talks to use Google’s Gemini AI to strengthen Siri. Analysts expect the company to tout the AI processing power of its next-gen Apple Silicon chips, paving the way for an “agentic Siri” that can handle tasks in the background without draining device batteries.

While Apple’s customer base remains loyal, experts warn the company now has months, not years, to prove it can match competitors in AI and form-factor innovation. “By this time next year, if Siri still disappoints and the foldable isn’t out, Apple’s content base could erode,” said Bob O’Donnell of TECHnalysis Research.
