Shares of MYT Netherlands Parent B.V. (MYTE), the parent company of luxury e-commerce platform Mytheresa, plunged 6.6% in pre-market trading on Monday after announcing a strategic acquisition of online luxury fashion retailer YOOX NET-A-PORTER (YNAP) from Richemont.

Mytheresa has struck a deal to acquire YNAP in exchange for a 33% equity stake in the company. This transaction aims to create a leading global digital luxury group by merging YNAP's Luxury division with Mytheresa, combining their diverse multi-brand offerings.

While the acquisition could potentially bring benefits such as increased scale, product diversification, and synergies, investors appear to be concerned about the potential risks and challenges associated with the deal. These may include integration complexities, operational difficulties, and potential dilution of existing shareholders' stakes due to the issuance of new shares to Richemont.
