How Should We Inform Employees About a Company Name Change? Seeking Your Advice!

Dear all,

I wish to know the procedure to inform the employees regarding a company name change. Is there any necessity to provide a letter to employees who have worked in "Company A" and continued their employment with "Company B" after the name change? I am looking for valuable guidance as soon as possible.

Thank you.

Just prepare a general notice on the new company letterhead mentioning that the company name has changed with an effective date. In the last paragraph, mention that all the existing terms and conditions of employees will continue. Their date of joining will also remain unchanged.
