Oman's Raysut Cement has halted production for up to 10 days after the tropical Cyclone Mekuna damaged its property.
Heavy rain and strong winds caused "external damage" and waterlogged the company's production facilities and stock yard.
Raysut Cement's chief executive officer, Joey Ghose, who took the top job in November 2017, said the company's buildings had been battered by Cyclone Mekuna for two days.
He said it was unclear how extensive the damage was, but added that Raysut insurers had been contacted over the issue.
"We will disclose the losses when it is available, and after loss evaluation and quantification [has been completed]," Ghose said in an update on the Muscat Securities Market (MSM).
Cyclone Mekuna hit Oman on Friday, 25 May.
The Sultan of Oman's Armed Forces and the Ministry of Defence have both been mobilised to deal with the weather conditions.
On Sunday 27 May, Oman's Ministry of Defence launched emergency engineering repair works to the Adonub Bridge in the Wilayat of Salalah, which was damaged by Cyclone Mekuna, according to the Oman News Agency.
Recovery and salvage operations have also been launched at the Salalah Port, which suffered "extensive damage" as a result of the storm, according to a statement on MSM.
Hilton Salalah Resort said it had been forced to close until further notice as a result of the storm, following damage to various parts of the building.
Sembcorp Salalah Power and Water Company said it had "temporarily shut down" its water plant due to a "severe worsening of sea conditions during the cyclone".
