Aptiv (APTV) Q4 2025 earnings review
Record Revenue, But Margins and Earnings Compress
Aptiv delivered record full-year revenue and 5% growth in Q4, but profitability metrics deteriorated significantly. While the top line expanded to $5.2B, Net Income fell 48% YoY to $138M, hammered by a spike in tax expenses and margin compression in the high-tech Advanced Safety segment. The narrative is dominated by the upcoming Q1 2026 spin-off of the EDS business (to be named 'Versigent'), effectively splitting the company. While 2026 guidance implies a return to margin expansion, the immediate Q4 reality shows a company where sales growth is currently failing to flow through to the bottom line.
🐂 Bull Case
The ECG segment remains a bright spot, growing revenue 4% and Adjusted Operating Income 8% in Q4. It successfully expanded margins despite broader macro headwinds, demonstrating pricing power and operational efficiency.
The separation of 'Versigent' (EDS) is on track for Q1 2026. This creates two pure-play entities: a high-growth tech business (New Aptiv) and a cash-generative industrial business (Versigent), potentially eliminating the conglomerate discount.
🐻 Bear Case
The high-growth Advanced Safety & User Experience (AS&UX) segment saw profits dive 17% YoY in Q4 despite 3% revenue growth. This significant negative operating leverage questions the segment's near-term scalability.
Q4 tax expense tripled YoY ($196M vs $64M), and full-year results were marred by a $300M valuation allowance increase due to OECD Pillar Two rules. These non-operational items are severely depressing GAAP earnings.
⚖️ Verdict: ⚪
Neutral. The impending spin-off provides a clear catalyst, and 2026 guidance suggests improvement. However, the Q4 profit degradation in the core AS&UX segment and the messy GAAP earnings (taxes/impairments) make the current execution look sloppy.
Key Themes
Advanced Safety Segment Margin Compression
A major concern in Q4 was the performance of the Advanced Safety & User Experience (AS&UX) segment. While revenue grew 3% to $1.42B, Adjusted Operating Income fell 17% to $161M. This implies a significant margin contraction, likely driven by launch costs, mix shifts, or inability to offset commodity/FX pressures.
Electrical Distribution Systems (EDS) Volume Growth
Ahead of its spin-off, the EDS segment delivered the strongest top-line performance, with revenue up 8% to $2.30B. While profitability dipped slightly (-2%), the volume growth indicates robust demand for vehicle architecture and electrification solutions.
Tax Expense Volatility
GAAP Net Income is being crushed by tax items. Q4 tax expense was $196M (vs $64M prior year). For FY25, tax expense hit $700M (vs $223M prior year), driven by a $300M valuation allowance related to OECD Pillar Two guidance. This creates a massive wedge between Adjusted and GAAP figures.
Strategic Separation: Versigent
The spin-off of the EDS business, branded 'Versigent', is the central strategic narrative. Set for Q1 2026, guidance is already split: 'New Aptiv' targets ~18.6% Adj EBITDA margins, while 'Versigent' targets ~10.7%. This separates the software/tech margin profile from the industrial component profile.
FX and Commodity Headwinds
Commodity costs and foreign exchange impacted Q4 Adjusted Operating Income by $66M. For the full year, this impact was $207M. While the company is growing revenue, these external factors continue to erode the flow-through to profitability.
Engineered Components Profitability
The Engineered Components Group (ECG) was the standout performer for efficiency. It generated $270M in Adjusted Operating Income on $1.64B revenue, growing profit by 8% YoY. It was the only segment to grow profit in Q4, effectively offsetting inflation and FX pressures.
Other KPIs
Stable/Decelerating. Margin was 16.5% in 24Q4. The compression to 15.5% (calculated: $798M / $5,153M) reflects the inability to fully offset FX/commodity headwinds and the weakness in AS&UX profitability.
Decelerating. Down from $1,060 million in the prior year period. While full-year OCF of $2.19B remains healthy, the Q4 drop indicates working capital timing or cash tax headwinds affecting conversion.
Reversing. Collapsed from $1,787 million in FY24. Heavily impacted by a $648M non-cash goodwill impairment (Wind River) and $300M tax valuation allowance. While 'Adjusted' Net Income rose, the quality of reported earnings is very low this year.
Guidance
Accelerating. The midpoint ($21.47B) implies ~5.2% growth over FY25's $20.4B. This suggests management sees volume recovery or new program ramps outpacing the ~3% growth seen in 2025.
Accelerating. Guidance implies expansion from the ~15.8% level achieved in FY25. This relies on the successful execution of the spin-off and operational improvements in 'New Aptiv' (guided to 18.6% margin) vs 'Versigent' (10.7%).
Decelerating. The midpoint ($1.65) is below the Q4 2025 result of $1.86 and below Q1 2025's $1.69. This suggests the first quarter of the transition year will face seasonally weaker profitability or separation-related friction costs.
Stable/Weak. This range is notably lower than historical conversion rates would suggest for a $21B revenue company, likely due to separation costs ($440-540M OCF for New Aptiv seems low relative to EBITDA, implying heavy capex or one-time cash outflows).
Key Questions
Advanced Safety Margin Collapse
Adjusted Operating Income in the Advanced Safety & User Experience segment fell 17% in Q4 despite revenue growth. Was this driven by specific launch costs, pricing pressure, or mix? When should we expect this segment's margins to stabilize?
Versigent Margin Profile
The pro forma guidance for Versigent suggests an Adjusted EBITDA margin of ~10.7%. Given the 8% revenue growth in EDS this quarter, is this margin structurally capped, or is there a path to mid-teens profitability as a standalone entity?
Tax Expense Normalization
With the $300M valuation allowance and significant volatility in effective tax rates this year, what is the normalized cash tax rate we should model for the two separate entities (New Aptiv vs. Versigent) in 2026 and beyond?
Q1 2026 Earnings Step-Down
Q1 2026 EPS guidance at the midpoint ($1.65) is lower than Q1 2025 ($1.69). Given the 5% revenue growth trajectory, what specific headwinds (costs, separation dis-synergies) are weighing on Q1 profitability?
