The AI rally continued this earnings season. However firms constructing the underlying {hardware} powering the increase warned that the Iran battle is placing stress on their provide chains and profitability.
A spiraling battle within the Center East has seen oil costs skyrocket and provide chains essential to the tech sector hamstrung. Shortages of key chipmaking supplies, together with helium, are anticipated because the U.S. and Iran stay locked in a standoff.
TSMC, which manufactures Nvidia chips, stated the state of affairs within the Center East may impression its profitability, with costs for sure chemical substances and gases prone to enhance. Foxconn, the world’s largest contract electronics producer, singled out occasions within the Center East as a key problem this yr. Chipmaker Infineon stated prices would rise for valuable metals, power and freight on account of the battle.
The businesses’ state of affairs may worsen, Francisco Jeronimo, analyst at IDC, instructed CNBC.
“We will count on additional damaging impression this yr…the value of fuel, power and freight are at an all-time excessive and are prone to stay excessive for a couple of extra quarters, even when the state of affairs de-escalates,” he stated. “Even with a possible ceasefire, the supply-side harm does not enhance in a single day.”
Rising prices
Provide chain disruption and power prices are two areas of concern for chip firms amid the Iran battle.
Helium, which is principally produced as a by-product of pure fuel manufacturing, is essential to semiconductor manufacturing. Qatar, the world’s second-largest provider which owns a part of the world’s largest fuel subject, has seen its export capability hamstrung by Iranian strikes. Qatar supplied over 30% of the market in 2025, based on S&P International.
Entry to different supplies essential to the semiconductor manufacturing course of, resembling bromine and aluminium, have additionally been impacted. In March, chip patrons in Europe had been paying extra and tapping backup shops because the battle disrupted air freight.
Chip firms “all perceive they should diversify to be much less depending on a particular area,” stated Jeronimo. From a short-term perspective, TSMC is constructing stock buffers and diversifying sourcing, he added.
The Taiwanese chipmaker’s technique was “to repeatedly develop multi-source provide options to construct a well-diversified international provider base and to enhance the native provide chain,” Chief Monetary Officer Wendell Huang stated on an earnings name in April.
VAT Group, which provides parts to chipmakers, stated it skilled provide chain disruption and needed to reroute shipments of products to clients on account of the battle. Whereas the corporate stated it anticipated no materials impression on its 2026 full-year outlook, gross sales for its first quarter took a success of 20-25 million Swiss francs ($25.5 million to $32 million), the corporate reported.
Extended battle considerations
Rising power prices are at the moment a “most acute” downside for producers and fabs, Sebastien Naji, analyst at William Blair, instructed CNBC.
However the longer the battle within the Center East lasts, the “extra vital the second and third order impacts on element prices, vendor margins and total AI knowledge heart economics,” he added.
Provide chain impacts and rising prices which were uncovered this firm earnings season may simply mark the start of the headwinds ought to a U.S.-Iran stalemate proceed to play out.
“If the blockade continues via the summer time, we usually tend to revisit the dangers and impacts in future earnings durations,” Naji stated.
As of Monday, there have been no indicators that the U.S. and Iran had been any nearer to reaching a deal as U.S. President Donald Trump ramped up threats to Tehran on Sunday.
Japanese semiconductor testing tools maker Advantest stated in its earnings that the “enterprise atmosphere surrounding the corporate stays unpredictable” on account of “considerations of escalating tensions within the Center East doubtlessly resulting in a slowdown within the international economic system.”
Whereas the direct impression on earnings was at the moment restricted, the corporate stated, sure prices, together with in logistics, had already arisen, and provide chain shortages may emerge.
However to date, the AI increase is cushioning any investor warning, with shares persevering with to rally.
“Any disruption to date has been utterly overshadowed by the upswing in investor confidence in AI,” Michael Area, chief fairness strategist at Morningstar, instructed CNBC, pointing to large features in latest weeks from chip firms.
Nasdaq’s PHLX Semiconductor Sector Index — comprising the 30 largest U.S.-traded chip firms — has risen 41% over the previous three months.
Philadelphia SE Semiconductor Index shares over the previous three months.
“The businesses that might be insulated [against impacts from the Iran war] are those with security inventory, diversified sourcing and pricing energy on manufacturing capability,” stated Jeronimo.
“Everybody else might be beneath growing price stress for the remainder of 2026.”
