Red flags were thrown up by analysts today regarding the prospects of Stratasys, Ltd. (NASDAQ:SSYS), after the 3D printing giant reported disappointing results for the third quarter and lackluster guidance for the next. In reaction, Stratasys shares tumbled 15% as of this writing.

Stratasys reported revenues and EPS of $157.2 million and $0.00 compared with prior consensus expectations for the period of $174.5 million and $0.06, respectively. The company lowered its guidance for revenues from $662M to $673M, compared to the previously provided ranges of $700M to $730M.

As such, Canaccord analyst Robert Burleson reiterated a Hold rating on shares of Stratasys, while lowering the price target to $20 (from $18), which represents a slight upside potential from current levels.

Burleson noted, “We are reducing our estimates on Q4 guidance and our expectation for continuing weak demand into 2017. Excess capacity at customers and increasing competition are pressuring systems sales. While consumables delivered healthy Y/Y growth, we see risk of slowing high margin consumables going forward if systems don’t pick. We could get more constructive with evidence of better systems demand.”
