"We're off to a good start in 2019, with solid volume growth from our expanded health plan access," said Steve Rusckowski, Chairman, President and CEO. "As we anticipated, volume accelerated through the quarter, and we look forward to continued progress as a member of UnitedHealthcare's Preferred Lab Network beginning July 1.

Note on Non-GAAP Financial Measures

As used in this press release the term "reported" refers to measures under the accounting principles generally accepted in the United States ("GAAP"). The term "adjusted" refers to non-GAAP operating performance measures that exclude special items such as restructuring and integration charges, amortization expense, excess tax benefit ("ETB") associated with stock-based compensation, and other items.

Non-GAAP adjusted measures are presented because management believes those measures are useful adjuncts to GAAP results. Non-GAAP adjusted measures should not be considered as an alternative to the corresponding measures determined under GAAP. Management may use these non-GAAP measures to evaluate our performance period over period and relative to competitors, to analyze the underlying trends in our business, to establish operational budgets and forecasts and for incentive compensation purposes. We believe that these non-GAAP measures are useful to investors and analysts to evaluate our performance period over period and relative to competitors, as well as to analyze the underlying trends in our business and to assess our performance. The additional tables attached below include reconciliations of adjusted measures to GAAP measures.
