Yodel said it was reviewing its “strategic options” as speculation grew over its future.
National media reports claimed the parcel delivery firm was considering calling in administrators after failing to find a buyer.
The company has been on the hunt for a new owner since last summer when it confirmed that it had received a number of “unsolicited approaches”.
It appointed corporate finance advisory service Clearwater International to lead a full strategic review on behalf of its shareholders.
Yodel has extended its financial year from June to December 2023 and was meant to have published figures for 2022 by the end of last year but they are currently overdue.
Last month it announced 2023 had been a record year, with volumes up 3% and revenues increasing by 3.4%.
However, Citizens Advice rated the firm as the joint worst of the UK’s largest courier companies, along with Evri.
Yodel scored just two stars out of a possible five when measured against customer service, delivery problems and accessibility needs.
It employs around 10,000 staff and delivers goods for retailers such as John Lewis, Argos and AO World.
Only this week it said it had appointed two senior executives to bolster its leadership team and strengthen its business.
Asked to comment on the media reports, a Yodel spokesman said: “A process to review strategic options is nearing its conclusion with a number of parties looking to acquire the business.
“In the meantime Yodel is focused on business as usual.”
