DUBLIN--(BUSINESS WIRE)--April 28, 2015--ICON plc (NASDAQ: ICLR), a global provider of drug development solutions and services to the pharmaceutical, biotechnology and medical device industries, today reported its financial results for the first quarter ended March 31, 2015.

In the first quarter net revenue grew 11% year on year to $388.2 million from $349.6 million in the same quarter last year.

Income from operations was $66.7 million or 17.2% of revenue, compared to $43 million or 12.3% for the same quarter last year.

Net income was $56 million or 90 cents per share on a diluted basis, compared with $36.2 million or 57 cents per share for the same quarter last year.

Operating income margin in quarter 1 included a one off foreign exchange revaluation gain of approximately $2.9 million. When this is excluded, operating income margin in the quarter equated to 16.4% and earnings per share were 86 cents.

Taking into account recent foreign exchange movements, earnings guidance for the full year 2015 has been increased from a range of $3.45 - $3.60 to a range of $3.60 - $3.70 and revenue decreased from a range $1,610 - $1,675 million to a range of $1,600 - $1,650 million.

Days sales outstanding, comprising accounts receivable and unbilled revenue less payments on account, were 47 days at March 31, 2015, compared with 40 days at the end of December 2014.

For the quarter ended March 31, 2015, cash generated from operating activities was $61.1 million and capital expenditure was $10.7 million. In addition during the quarter, the acquisition of MediMedia Pharma Solutions was completed for an initial cash consideration of $105 million. Consequently the company’s net cash amounted to $172 million at March 31, 2015, compared to net cash of $216 million at December 31, 2014.

CEO Ciaran Murray commented, "Our first quarter represents a solid start to 2015. Revenue grew by 13% year on year on a constant dollar organic basis. Excluding the one-time foreign exchange benefit, our operating margins expanded to 16.4% and earnings per share were 86 cents, an increase of 51% over last year. During the quarter we saw a further strengthening of the US dollar and as a result we have increased earnings guidance for the full year from a range of $3.45 - $3.60 to a range of $3.60 - $3.70 and decreased revenue guidance from a range of $1,610 - $1,675 million to a range of $1,600 - $1,650 million.”

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), this press release contains certain non-GAAP financial measures, including non-GAAP operating and net income and non-GAAP diluted earnings per share. While non-GAAP financial measures are not superior to or a substitute for the comparable GAAP measures, ICON believes certain non-GAAP information is useful to investors for historical comparison purposes.
