Why is Aptiv stock sliding today?
Aptiv (APTV) shares fell 5.8% to $41.65, a 52-week low, after reporting Q3 earnings that beat estimates but provided disappointing Q4 2026 guidance. Adjusted EPS was $1.42 vs. $1.33 expected, and revenue was $3.2B vs. $3.18B expected. Q4 2026 EPS guidance of $1.35-$1.55 (midpoint $1.45) was below the $1.62 consensus. Management cited semiconductor cost inflation and soft European markets. Janus Henderson exited its position, while StoneX maintained a Buy rating with a $75 target.
