Genuine Parts Company's stock tumbled 6.05% in pre-market trading on Tuesday following the release of its second-quarter earnings report, which included a lowered full-year profit outlook.

The automotive and industrial parts distributor narrowed its 2026 diluted earnings per share forecast to a range of $5.90 to $6.40, down from its previous projection of $6.10 to $6.60. The company cited softer regional demand and higher restructuring and separation-related costs for the adjustment. While it reaffirmed its adjusted EPS outlook of $7.50 to $8.00, the cut to its GAAP profit guidance weighed on investor sentiment.

Management attributed the more cautious stance to a challenging consumer environment marked by inflation and weaker spending, which are pressuring the automotive sector. For the second quarter, the company reported a decline in net income to $227.6 million, or $1.65 per share, down from $254.9 million, or $1.83 per share, a year ago, despite a 6% increase in net sales to $6.54 billion.
