Opening Summary
Xometry, Inc. (XMTR), an AI-powered online marketplace connecting buyers with a global network of custom-manufacturing suppliers, saw its stock fall sharply on Thursday. Shares traded down roughly 9.4% to about $91.33, compared with a prior-session close of $100.82, as investors reassessed the custom-manufacturing sector ahead of the company's third-quarter earnings release. The catalyst cited most broadly by markets was a peer-driven read-through: rival Proto Labs (PRLB) plunged after reporting that higher raw-material costs and factory investments squeezed its gross margin, raising concerns that similar pressures could reach XMTR.
Sector Sympathy After Proto Labs' Margin Warning
The primary driver of Thursday's decline was a sector-wide repricing of on-demand manufacturing stocks. Proto Labs posted record third-quarter revenue of $154.3 million and raised its full-year growth outlook, yet its shares still fell roughly 15% because its non-GAAP gross margin dropped to 44.5%, down 230 basis points sequentially. Management attributed the compression to higher raw-material costs, machine upgrades, and increased labor and contractor support.
The read-through for XMTR is direct. Xometry operates a similar marketplace model, and its own marketplace gross margin slipped to 34.7% in the second quarter, down from 35.4% a year earlier. With XMTR scheduled to report third-quarter results on November 3, investors are now asking whether the same cost inflation weighing on Proto Labs will also pressure Xometry's margins.
Valuation and Technical Pressures
Beyond the peer catalyst, XMTR entered the session priced for strong execution. The stock had run up sharply over the past year, and its valuation multiple remained elevated relative to its own history, leaving little room for disappointment. Against that backdrop, the stock had already pulled back roughly 18% over the prior month.
The selloff also carried a technical dimension. The shares broke below their 50-day moving average, and intraday trading saw the price slide toward the $90 level, a round-number support zone. This breakdown, combined with momentum indicators turning negative, amplified programmatic and momentum-driven selling during the session.
Market Context and Trading Activity
Trading was heavy as investors de-risked positions ahead of next week's earnings, with volume running well above the stock's typical daily average. The decline outpaced the broader market and aligned closely with weakness across custom-manufacturing and industrial-tech peers, signaling that Thursday's move was company- and sector-specific rather than a broad-market selloff.
The pullback also reflects heightened sensitivity to cost trends. While Xometry has delivered accelerating revenue growth and improving adjusted EBITDA in recent quarters, its international segment remains unprofitable, and gross margin has yet to reach the company's long-term target range of 35% to 40%. Recent insider selling by several executives added to the cautious tone heading into the print.
What Comes Next for XMTR
The immediate focus is XMTR's third-quarter earnings report on November 3. Investors will be watching whether marketplace revenue growth remains strong, whether gross margin holds up against rising input costs, and whether management reaffirms or adjusts its full-year revenue growth and adjusted EBITDA guidance. Analysts remain broadly constructive on the name, with consensus carrying a Buy rating, but the market's reaction to Proto Labs shows that strong top-line growth may not be enough if margin trends deteriorate.
Key risks include persistent raw-material inflation across the supplier network, the pace of international profitability improvement, and a valuation that remains sensitive to any guidance shortfall. Sector developments, particularly around manufacturing demand in aerospace, defense, robotics, and data centers, will also shape sentiment in the weeks ahead.
