3D Systems (DDD) shares were falling past 5% in after-hours trading Wednesday after the company said it expects Q3 revenue of about $112.9 million, down from $123.8 million a year earlier.

Analysts polled by Capital IQ expect $115.7 million.

3D also said it will delay the filing of its quarterly report on Form 10-Q for the quarter ended Sept. 30.

"The delay in filing was caused by the need for an interim valuation of goodwill and long-lived assets, triggered by recent performance of the company's stock and market volatility as of September 30, 2024," the company said.

"This evaluation is normally conducted in the fourth quarter and so represented additional unplanned efforts for its completion in the third quarter. It has no impact on the company's operations," it said.

3D said it expects to release Q3 results the week of Nov. 25.
