The Durham, N.C.-based company saw its stock retreat to $185.16 in morning trading, extending a year-long decline to 9.6%. While IQVIA’s revenue projections for 2026—set between $17.15 billion and $17.35 billion—actually outpaced the $17.07 billion Wall Street expected, investors focused on a narrower-than-expected adjusted earnings per share (EPS) range of $12.55 to $12.85. According to data from FactSet, analysts had anticipated an average of $12.93 per share.

Interest Expenses Weigh on Outlook

Management attributed the conservative guidance to an expected $80 million increase in interest expenses. This spike stems from the annualization of financing activities initiated in 2025 and planned refinancing scheduled for 2026. Despite the cautious outlook, the company’s recent operational performance remained robust. IQVIA reported fourth-quarter net income of $514 million, or $2.99 per share, marking a significant jump from the $437 million earned during the same period the previous year.

Revenue for the final quarter grew by 10.3% to reach $4.36 billion, surpassing the $4.24 billion consensus forecast. However, the market reaction suggests that the immediate gains in top-line growth were not enough to offset concerns regarding rising debt costs and the company's long-term profitability trajectory.
