"The container accidentally ran aground after a suspected gust of wind hit it", Evergreen Marine told AFP.
There was "a grounding incident" in the Suez Canal, said Mr Alok Roy, fleet director of BSM Hong Kong, the Ever Given's ship manager.
A United Nations database listed the Ever Gren as being owned by Shoei Kisen KK, a ship-leasing firm based in Imabari, Japan. "There have been no reports of injuries or pollution".
Egyptian tug boats have thus far failed to pull the ship free.
Canal authorities could not be immediately reached early Wednesday.
The Ever Given, a 59m long cargo ship en route from China to Rotterdam, has become stuck one of the narrowest parts of the canal. Because of the Ever Given's position, southbound traffic also was blocked by the ultra large container ship. Oil prices briefly rose on news of the disruption before pulling back. Shipping companies have been turning to mega-sized vessels to help improve economies of scale, while some key routes - including the Suez Canal - being widened and deepened over the years to accommodate them.
"The Egyptian government certainly did not expect the route to be blocked both ways by a single ship", said Flavio Macau, a supply chain management expert at Edith Cowan University in Australia, in an interview with The Washington Post.
About 12% of the world trade volume passes through the man-made canal, which is a major source of hard currency for Egypt.
Almost everything shipped from Asia and the Middle East to Europe and vice versa passes through the Suez Canal. About 12% of global trade, nearly 10% of seaborne oil trade and 8% of global LNG passes through the canal.
A number of ships waiting can also be seen waiting inside the canal and queuing in the Red Sea to the south, with dozens of others waiting at points inside the canal and in the Mediterranean to the north. In one of the most serious delays, the canal was closed for three days in 2004 after an oil tanker, Tropic Brilliance, got lodged.
Any prolonged disruption would mean ships need to reroute, which would likely drive up freight costs, said Chun Hyungjin, research fellow at Korea Maritime Institute.
Without it, vessels would have to sail all the way around the continent of Africa to get from Europe to Asia.
The shipping industry has had a tumultuous year since the Covid-19 pandemic began roiling global trade in 2020.
