Why Is GENUINE PARTS CO (GPC) Stock Down Today?

GPC stock closed down 9.74% at $110.50 after the company released second-quarter 2026 results that included both positive and negative updates. While the firm reported non-GAAP earnings per share of $2.15 and revenue of $6.5 billion, both above estimates, it also cut its full-year GAAP profit forecast. The stock opened with a small gap up but quickly reversed into a sharp decline, reaching a session low of $109.50 before settling near that level.
