Saudi Aramco has overtaken Apple as the world's most valuable company, underscoring the recent surge in oil prices that have boosted the energy giant this year.
Aramco is now worth about US$2.43 trillion, compared with Apple's $2.37 trillion, according to data from Refinitiv.
Market capitalizations fluctuate frequently: earlier this year, Apple hit the US$3 trillion mark, becoming the first to do so and making it by far the most valuable company on the planet.
Aramco at one point also held that mantle after a historic initial public offering in 2019, which propelled its valuation to US$2 trillion.
But the latest market moves point to how the outlook for energy and tech producers have shifted lately.
This year, oil prices have soared to record highs, particularly on concerns about disruptions of supply from Russia since its invasion of Ukraine.
Brent crude, the global benchmark, has climbed about 36 per cent so far this year, and was last trading at US$106.2 a barrel.
That has buoyed players like Saudi Aramco, whose shares are up 27 per cent so far this year.
Meanwhile, Apple's stock has fallen more than 17 per cent since January.
The iPhone maker has recently been weighed down by major supply chain headaches, particularly in China, where several of its suppliers' factories have been temporarily caught in the country's COVID lockdowns.
Last month, Apple warned of huge losses related to the ongoing situation, saying that production and logistics issues could hit its sales by as much as US$4 billion to $8 billion this quarter.
Apple's constraints were "primarily centered around the Shanghai corridor," CEO Tim Cook said in an earnings call.
Dan Ives, managing director of equity research at Wedbush Securities, called the impact of the lockdowns "the albatross for the June quarter," saying in a report that Apple's supply chain woes in China would likely remain the "peak worry" for investors in the short term.
But concerns may "subside" in the second half of the year, when the company is expected to launch a new iPhone 14, he added.
