After an extreme deep dive to uncover what is actually happening with Morphe, it appears that they have filed for Chapter 11 Bankruptcy. Very shortly after all of their US retail locations closed, they announced this filing. According to Dani James, Morphe struggled heavily throughout the pandemic, seeing as no one really needed makeup during lockdown. Additionally, Morphe has recently had to cut ties with multiple different partners for reasons that have not been officially disclosed. James also stresses that Morphe itself is not the one filing for bankruptcy, but rather the parent company, Forma has. Forma emphasized in the statement cited by James that rather than this being a business ending decision, it is rather a business repositioning decision. So although they are filing bankruptcy, they should not be ending as a business entirely.
