Aptiv (APTV) is down sharply today after reporting Q1 2026 results that beat estimates but pairing them with guidance that came in light versus expectations. The key pressure point is the outlook: Aptiv guided Q2 2026 adjusted EPS of $1.30–$1.50 versus a $1.52 consensus estimate, and FY2026 adjusted EPS of $5.70–$6.10 versus $6.18 consensus, signaling a softer earnings trajectory than the market was positioned for.

For Q1 2026 (ended March 31, 2026), Aptiv reported revenue of $5.1 billion (+5% reported; +1% adjusted for FX/commodities) and adjusted EPS of $1.71, essentially matching the narrative of solid execution into the quarter. However, profitability indicators were less supportive: adjusted EBITDA margin was 14.8% versus 15.7% a year ago, with commodity costs and FX headwinds cited as key drivers, and free cash flow was negative in the quarter.

The guidance that investors are reacting to is framed as “New Aptiv” (excluding the Electrical Distribution Systems business following the April 1, 2026 spin into Versigent). Aptiv’s pro forma Q2 outlook calls for net sales of $3.2–$3.4 billion and adjusted EPS of $1.30–$1.50, while full-year 2026 net sales are guided at $12.8–$13.2 billion with adjusted EPS of $5.70–$6.10. With the stock setting a new baseline around the post-spin profile, any mismatch versus consensus expectations for the new reporting perimeter can translate into an outsized move. (aptiv.com)

Investors will likely focus on whether management can stabilize margins as FX and commodity pressures persist, and whether the slimmer New Aptiv can deliver cleaner conversion to cash flow in coming quarters after the Q1 outflow. Another near-term sensitivity is whether sell-side estimates reset lower to align with the company’s FY2026 EPS range, which can pressure valuation and sentiment even if underlying demand trends remain steady.
