Xometry, Inc. (XMTR) experienced a significant pre-market plunge of 7.26% on Tuesday. The sharp decline occurred as the market digested the company's announcement of a planned leadership transition.

The company announced that co-founder and CEO Randy Altschuler will step down from his role effective July 1, transitioning to Executive Chair of the board. President Sanjeev Singh Sahni, who joined the company in January 2025, will succeed him as Chief Executive Officer and join the board of directors. This news of a founder-CEO stepping down appears to have introduced uncertainty for investors, leading to the pre-market sell-off.

This negative market reaction unfolded despite the company concurrently reporting strong fourth-quarter 2025 financial results that beat analyst expectations for both revenue and adjusted EBITDA, alongside a positive revenue outlook for 2026. The immediate focus for traders in the pre-market session, however, was squarely on the implications of the upcoming change in leadership.
