April 1 broke Aptiv into two companies — and the market is repricing what's left.

Before. Pre-spin Aptiv was a $20B Tier-1 supplier with three gears: high-margin Engineered Components connectors at 26% gross margin, Advanced Safety/UX (ADAS plus Wind River software) at 19%, and Electrical Distribution wire harness at 12%. The bundle was priced like its lowest gear.

Pivot. On April 1, 2026 the wire-harness business spun off as Versigent (NYSE: VGNT) — one VGNT for every three APTV shares. Aptiv received a $2.125B cash distribution earmarked for $2.1B of debt paydown. RemainCo pro forma: ~$12.4B revenue, ~18.6% EBITDA margin, ~$750M FCF — a comp basket closer to Visteon and BorgWarner than Lear and Magna.

Today. APTV fell 10.7% on spin day; JPMorgan, UBS, and TD Cowen have all cut price targets in the three weeks since. The Street is repricing RemainCo, not the combined entity. The first standalone quarter prints May 5, 2026.

A single Q1 EBITDA margin print on May 5 will resolve a $60-wide debate.

• Re-rate case ($110). RemainCo's right comp set is Visteon (11.8% EBITDA margin, 19x P/E), BorgWarner (14.6%), and TE Connectivity. 12x EV/EBITDA on $2.7B of normalized EBITDA, with leverage falling from 2.8x to 2.0x as the $2.1B distribution clears debt.
• De-rate case ($48). RemainCo's adjusted op margin of 12.1% already trails BorgWarner (14.6%) and Visteon (11.8%) — same comps, opposite read. 9.5x on FY25's actual $2.23B EBITDA, no margin recovery, Mexico's January 2026 13% wage hike biting before stranded costs roll off.
• The Street can't agree. 19 of 23 analysts rate Strong Buy with a $91 average target — yet every disclosed move in April 2026 has been a cut: JPM $105→$83, UBS $97→$80, TD Cowen $93→$90. FY26 EPS consensus has dropped from $8.38 to $6.22 in 30 days.

FY2025 broke the headline number and left the cash line standing.

Operating margin halved on a Q3 Wind River goodwill impairment ($648M), separation costs, and a Swiss tax write-off — while operating cash flow held above $2.1B. The bull says GAAP is noise and cash conversion is intact. The bear says the FCF beat is partly capex at a 12-year low (3.2% of sales versus a 4.5% norm) plus working-capital release as OEM volumes drop. Two more quarters of operating cash flow tracking will resolve which is right.

A decade of transformative bets, mostly written down.

• Wind River. Paid $4.3B in December 2022 to anchor the software-defined-vehicle pitch; impaired $648M in Q3 2025. Management called the long-term thesis intact while citing slower 5G and SDV adoption — known headwinds absorbed for two years before the carrying value broke.
• Motional. The Hyundai robotaxi JV pitched as production-ready by 2023 went from a 50% stake to ~13% by year-end 2025; future funding obligations dropped. The robots-by-2023 promise faded into footnotes.
• Buybacks at the wrong end. Share count fell from 282.9M to 213.1M since 2024 at average prices well above today's $60. The $5B authorization was announced the same morning as a $1.1B revenue guide cut in Q2 2024. Insiders have not bought open-market through the halving — only one ~9k-share purchase by the chief accounting officer on April 24, 2026.
