Adyen falls to 4-month low as half-year miss leads guidance trimming

** Shares in Dutch-based fintech Adyen ADYEN fall around 19% to their lowest in more than 4 months, after its half-year net revenue missed market expectations and trimmed annual growth guidance

** The firm, which is among top losers on the pan-European index STOXX SXXP, reported a 20% rise in half-year revenue that still missed market expectations, as U.S. tariffs and weaker dollar bit into fintech's sales

** The company expects that previously announced slight acceleration of its topline growth will be "unlikely" due to a slowdown in market volume growth expected to persist through the remainder of the year

** KBC Securities analysts calls the results "underwhelming", highlighting negative impact of a large-size customer to the main segment of Digital volumes, and the 2025 guidance downgrade

** "Underlying business & growth remains solid, particularly in Unified Commerce", the analysts add

** Up to the previous session's close, shares were up 1.9% YTD
