Samsung Profit Plunges 56% Amid AI Chip Woes, U.S. Export Curbs to China

Samsung Electronics reported a steep 56% year-on-year drop in Q2 operating profit, projecting earnings of 4.6 trillion won ($3.36 billion)—significantly below analyst expectations of 6.2 trillion won, according to LSEG SmartEstimate. This marks Samsung’s weakest quarterly performance in six quarters, as its semiconductor division continues to struggle with shifting global dynamics in the AI chip market.

The South Korean tech giant blamed its sharp decline on U.S. restrictions on AI chip exports to China, which have disrupted its sales pipeline. However, analysts pointed to delays in delivering high-bandwidth memory (HBM) chips to Nvidia as a major factor in its underperformance. Unlike rivals SK Hynix and Micron, which have seen strong AI-driven chip demand, Samsung has been slower to supply its latest HBM3E 12-layer chips, with customer evaluations still ongoing and no specific update on Nvidia shipments.

“Everything ultimately comes back to HBM,” said Ryu Young-ho, an analyst at NH Investment & Securities, noting that Samsung’s competitive edge hinges on reclaiming leadership in the HBM segment.

Revenue for the quarter is expected to come in nearly flat at 74 trillion won, down just 0.1% from a year ago. But the semiconductor division likely took the hardest hit, with analysts estimating its operating profit may have dropped over 90% to just 500 billion won, partly due to inventory value adjustments and unsold HBM stockpiles.

Adding to the challenges, potential U.S. tariffs and mounting competition in China—where Samsung still has a heavy market presence—are expected to weigh on both its chip and smartphone margins in the near term.

Samsung’s foundry business also saw falling earnings, attributed to low utilisation rates and inventory write-downs, stemming from the same U.S. AI chip export restrictions. However, the company expects foundry performance to gradually improve in the second half of 2025 as utilisation recovers with demand.

Despite the weak outlook, Samsung announced a 3.9 trillion won ($2.85 billion) share buyback, part of a broader 10 trillion won repurchase plan unveiled in late 2024. Investors remained cautious, with Samsung shares slipping 0.2%, while Korea’s benchmark KOSPI index rose 1.2% during morning trading.

Looking ahead, Samsung hopes to recover with upcoming phone launches and by expanding HBM sales beyond Nvidia to other customers. A full breakdown of business unit performance is expected on July 31, when the company releases its detailed Q2 earnings report.

Samsung Electronics Faces 39% Drop in Q2 Profit Amid Weak AI Chip Sales

Samsung Electronics is expected to report a 39% decline in its second-quarter operating profit, largely due to delays in supplying advanced memory chips to AI chip leader Nvidia, industry analysts said. The South Korean tech giant is forecast to announce an operating profit of 6.3 trillion won ($4.62 billion) for April to June, marking its lowest earnings in six quarters, according to LSEG SmartEStimate.

This downturn has raised concerns about Samsung’s ability to compete with rivals like SK Hynix and Micron in the rapidly growing market for high-bandwidth memory (HBM) chips used in artificial intelligence data centers. While its competitors have seen strong demand, Samsung’s growth has been limited by its heavy reliance on the China market, where U.S. export restrictions have curbed sales of advanced chips.

Analysts point out that Samsung’s latest HBM chips, specifically the HBM3E 12-high version, have not yet received Nvidia’s certification, slowing supply to the U.S. AI chip leader. Ryu Young-ho, senior analyst at NH Investment & Securities, noted that Samsung’s shipments to Nvidia are unlikely to be significant in 2025. Samsung has, however, started supplying the new chip to AMD since June.

Despite challenges in the chip segment, Samsung’s smartphone sales remain steady, supported by stockpiling ahead of potential U.S. tariffs on imported devices. Nonetheless, ongoing U.S. trade policies, including proposed tariffs on non-U.S.-made smartphones and possible restrictions on technology exports to Samsung’s Chinese plants, continue to create business uncertainty.

Samsung’s shares have underperformed this year compared to the KOSPI index, rising about 19% against the KOSPI’s 27.3% increase. As of Monday, Samsung shares dipped 1.9%, while the KOSPI rose 0.3%.

US May Target Samsung, Hynix, and TSMC Operations in China by Revoking Trade Authorizations

The U.S. Department of Commerce is considering revoking authorizations granted in recent years to major chipmakers Samsung, SK Hynix, and TSMC that allow them to receive U.S. goods and technology at their manufacturing plants in China, sources familiar with the matter said. This potential move would complicate operations for these foreign semiconductor firms in China, where they produce chips used across many industries.

While the likelihood of the U.S. actually withdrawing these authorizations remains uncertain, officials view the tactic as a contingency if the current trade truce between the U.S. and China deteriorates. A White House official emphasized that the U.S. is “just laying the groundwork” and expressed confidence the trade agreement would continue, including the agreed supply of rare earth minerals from China. The official clarified that “there is currently no intention of deploying this tactic,” but it remains a tool in case bilateral relations worsen.

Following early reports, shares of U.S. semiconductor equipment suppliers that serve Chinese plants dropped: KLA Corp fell 2.4%, Lam Research declined 1.9%, and Applied Materials sank 2%. Conversely, shares of Micron Technology, a key competitor to Samsung and SK Hynix in memory chips, rose 1.5%.

TSMC declined to comment, while Samsung and SK Hynix did not respond to requests for comment. Lam Research, KLA, and Applied Materials also did not immediately respond.

Background: In October 2022, the U.S. imposed broad restrictions on chipmaking equipment exports to China but provided foreign firms like Samsung and SK Hynix with letters authorizing shipments. In 2023 and 2024, these companies received “Validated End User” (VEU) status, which allows them to obtain U.S.-controlled products more quickly and reliably without needing multiple export licenses. However, VEU status comes with conditions such as equipment prohibitions and reporting requirements.

A Commerce Department spokesperson said chipmakers would still be able to operate in China if the authorizations are revoked. The enforcement mechanisms would align with licensing rules for other semiconductor firms exporting to China, ensuring the U.S. applies an equal and reciprocal approach.

Industry insiders warn that stricter U.S. controls could unintentionally benefit Chinese domestic competitors by making it harder for foreign companies to receive equipment, calling such a move “a gift” to China’s semiconductor industry.
