Adjusted to exclude one-time items, earnings per share were $1 even, a penny ahead of the consensus on Wall Street, where analysts were looking for revenues of $211.0 million.

“In Q1, we implemented new training programs, organizational changes in distribution, and launched external initiatives that will require time to drive more growth in the future,” chairman, president & CEO Michael Minogue said in prepared remarks. “We are confident in our ultimate global adoption because we know that our innovation improves clinical outcomes and patient quality of life.”

Abiomed said it now expects to report sales of $885 million to $925 million, down from $900 million to $945 million previously.
