William Blair recommends buying Xometry on post-earnings weakness

William Blair notes Xometry (XMTR) shares were down about 20% following the company reporting Q4 revenue and earnings that beat expectations and raising guidance for revenue growth in 2026 slightly. The analyst reports that investors the firm has heard from are “struggling to identify the reason for the pullback in the stock,” but most are pointing to two potential sources for concern – namely that cofounder and CEO Randy Altschuler announced that he will transition to executive chair of the board and some concerns regarding the deceleration in 2026 marketplace revenue growth incorporated into the guidance. The firm, which contends that the CEO transition was “well telegraphed for anyone following the company” and that management is likely starting the year with “somewhat conservative guidance,” keeps an Outperform rating on shares and recommends buying on weakness.
