CEO, Dr. Steve Cutler commented, "ICON's results in quarter four were in-line with our expectations as we continue to manage through a challenging transition period in our business. Encouragingly, we saw progress in a number of key areas in quarter four.

Gross business wins increased 8% sequentially, indicative of a positive, albeit volatile, underlying demand environment in both the large pharma and biotech divisions. Cash management was strong in quarter four, bringing full year free cash flow in line with our targeted $1.1 billion. On a full year basis, we reported growth across key metrics, including revenue growth of 2% as well as adjusted diluted earnings per share growth of 9.5% year over year. Finally, we are reaffirming our previously issued full-year 2025 guidance ranges for revenue and adjusted diluted earnings per share."

Other Information

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 adjusted EBITDA, adjusted net income and adjusted diluted earnings per share. Adjusted EBITDA, adjusted net income and adjusted diluted earnings per share exclude amortization, stock compensation, foreign exchange gains and losses, restructuring and transaction-related / integration-related adjustments. Free cash flow reflects cash generated from operating activities less capital expenditure. 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.

(a)	Stock-based compensation expense represents the amount of recurring expense related to the company's equity compensation programs (inclusive of employer related taxes).
(b)	Foreign currency (gains)/ losses, net relates to gains or losses that arise in connection with the revaluation, or settlement, of non-US dollar denominated assets and liabilities. We exclude these gains and losses from adjusted EBITDA and adjusted net income because fluctuations from period- to- period do not necessarily correspond to changes in our operating results.
(c)	Restructuring relates to charges incurred in connection with the company's realignments of its workforce, with the elimination of redundant positions as well as reviewing its global office footprint and optimizing its locations to best fit the requirements of the company.
(d)	Transaction and integration related costs include expenses associated with our acquisitions and any other costs incurred directly related to the integration of these acquisitions.
(e)	Transaction-related financing costs includes costs incurred in connection with changes to our long-term debt and amortization of financing fees. We exclude these costs from adjusted EBITDA and adjusted net income because they result from financing decisions rather than from decisions made related to our ongoing operations.
(f)	Represents the tax effect of adjusted pre-tax income at our estimated effective tax rate.
(g)	On April 20, 2023, the Company completed the purchase of the majority investor's 51% majority voting share capital of Oncacare Limited ("Oncacare"). This gave rise to an acquisition-related gain of $6.2 million. This gain was excluded from adjusted EBITDA and adjusted net income.
