Adyen seen down after new CFO appointment
** Shares in Adyen are seen down 2% to 3% after the Dutch fintech appointed a new CFO
** Niclas Neglen, current Klarna CFO, will join Adyen on February 1, 2027; previous CFO Ethan Tandowsky stepped down in a surprise move in May
** "Neglen will have to earn investors' confidence, given the perceived disconnect between the company's communication and investors' expectations," Jefferies says
** The broker notes that the volatile post-IPO period of Klarna during Neglen's tenure has left initial investor reactions rather negative
