Why is Medpace stock sliding today?
Medpace Holdings Inc (MEDP) fell 1.6% in after-hours trading after its Q3 2026 earnings report. Adjusted EPS of $4.84 beat estimates, but full-year revenue guidance of $2.835B-$2.855B missed expectations. The board replaced a $527M stock buyback program with a $1B program. Insiders sold $467M in shares over the past year. The S&P 500, Dow Jones, and NASDAQ also declined during regular trading.
