The AI rally continued this earnings season. However firms constructing the underlying {hardware} powering the growth warned that the Iran struggle 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 scenario within the Center East might influence its profitability, with costs for sure chemical compounds and gases more likely to improve. 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 because of the struggle.
The businesses’ scenario might worsen, Francisco Jeronimo, analyst at IDC, instructed CNBC.
“We are able to anticipate additional detrimental influence this yr…the worth of gasoline, power and freight are at an all-time excessive and are more likely to stay excessive for a couple of extra quarters, even when the scenario 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 struggle.
Helium, which is especially produced as a by-product of pure gasoline manufacturing, is essential to semiconductor manufacturing. Qatar, the world’s second-largest provider which owns a part of the world’s largest gasoline area, has seen its export capability hamstrung by Iranian strikes. Qatar offered over 30% of the market in 2025, in line with S&P World.
Entry to different supplies essential to the semiconductor manufacturing course of, akin to bromine and aluminium, have additionally been impacted. In March, chip consumers in Europe had been paying extra and tapping backup shops because the struggle disrupted air freight.
Chip firms “all perceive they should diversify to be much less depending on a selected 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 constantly 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 because of the struggle. Whereas the corporate stated it anticipated no materials influence on its 2026 full-year outlook, gross sales for its first quarter took successful of 20-25 million Swiss francs ($25.5 million to $32 million), the corporate reported.
Extended battle issues
Rising power prices are at present 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 important the second and third order impacts on part prices, vendor margins and total AI knowledge heart economics,” he added.
Provide chain impacts and rising prices which were uncovered this firm earnings season might simply mark the start of the headwinds ought to a U.S.-Iran stalemate proceed to play out.
“If the blockade continues by means of 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 gear maker Advantest stated in its earnings that the “enterprise setting surrounding the corporate stays unpredictable” because of “issues of escalating tensions within the Center East probably resulting in a slowdown within the international financial system.”
Whereas the direct influence on earnings was at present restricted, the corporate stated, sure prices, together with in logistics, had already arisen, and provide chain shortages might emerge.
However to date, the AI growth 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 Discipline, chief fairness strategist at Morningstar, instructed CNBC, pointing to massive positive factors 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 will probably 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 will probably be below rising value stress for the remainder of 2026.”
