Abiomed (ABMD) - Get Report lost a quarter of its market value on Thursday after the provider of technologies to support blood circulation in the heart reported fiscal-first-quarter revenue that missed the Wall Street consensus and it revised its full-year revenue estimate lower.

The stock finished 26% lower at $204.84.

New training programs, organizational changes in distribution, and certain external initiatives implemented in the first quarter "will require time to drive more growth," said Michael Minogue, chairman, president and CEO, in a statement.

Revenue for the quarter was 15% higher than a year earlier at $207.7 million. The FactSet consensus was $210.7 million.

For all of fiscal 2020, the Danvers, Mass., company now estimates revenue of $885 million to $925 million, up 15% to 20% from a year earlier. The company expects operating margin for the year of 28% to 30%. In the company's report for the fourth quarter of fiscal 2019, Abiomed estimated total revenue for fiscal 2020 would range $900 million to $945 million, up 17% to 23%.
