The firm filed a notice of intention to appoint an administrator last week as bosses battled to save the Sheffield based business.
But the Enquirer understands staff were sent an email last night confirming that the business will cease trading with an official announcement on its future due this morning.
The message sent by CEO Tom White said: “As you all know, our leadership team has been working tirelessly to secure the ongoing future of our business. Despite exploring all available options, it has now become clear that there is no near-term solution to secure our company’s future. Time has been against us and, as of this evening, all options have expired.
“I am devastated to say that as a result of this we must now take the necessary next steps. These will be detailed in an announcement at 11am tomorrow. We will host an online meeting and will send details of how to join ahead of this.
“We understand that some of you may wish to visit the factory in due course to collect any personal items or drop things off, and we will make arrangements to enable this, looking to have teams come in together where possible.
“Please know that we are fully committed to providing you with the support and information you need throughout this process. Your well-being remains our utmost priority, and we are here to assist you during this challenging time.
“I apologise for sending this message late in the day but I wanted to keep everybody as up to date with our situation as possible. Thank you for your understanding and cooperation.”
