Intuitive Surgical stock crashed late Thursday after the robotic surgery outlet reported lagging first-quarter sales and earnings that also decelerated.
Shares of Intuitive Surgical (ISRG) plummeted 6.2%, near 495, in after-hours trading on the stock market today. Intuitive Surgical stock ended the regular session 0.6% higher, at 528.06, during the regular session.
For the first quarter ended March 31, Intuitive Surgical earnings came in at $2.61 per share, on an adjusted basis. Intuitive Surgical earnings grew 7%, but decelerated from 20% growth in the fourth quarter. They also lagged the consensus of analysts polled by Zacks Investment Research for $2.70.
Revenue grew about 15% to $973.7 million, but that was also slower than 17% sales growth in the prior quarter. Analysts forecast $980 million in first-quarter sales.
Intuitive Surgical Earnings, Sales Fall Short
Procedure growth for Intuitive Surgical's robotic surgery system, da Vinci, remained in the double digits at 18%. The robotic surgery player also shipped 235 da Vinci systems, an increase of 27% vs. the year-earlier period.
"We are pleased with our first-quarter procedure and da Vinci system placements," Chief Executive Gary Guthart said in a written statement.
But the company didn't provide guidance for 2019. Analysts called for full-year Intuitive Surgical earnings of $11.99 per share on $4.31 billion in sales.
