ON's Divestitures: Efficiency Boost, but Structural Risks Remain

What happened

ON's divestitures under its Fab Right strategy aim to cut costs and improve efficiency, targeting higher-margin growth in AI data centers, automotive, and industrial markets. However, the company's recent filings and master report show that these moves are part of a broader restructuring that has led to significant charges and a reset of its manufacturing footprint. Despite strong free cash flow generation and a $6B buyback, ON trades at a high multiple with limited margin of safety, as the market prices a clean cyclical recovery that internal plans suggest may be slower. Key risks include sustained weakness in auto/industrial demand, LTSA amendments, and the possibility that gross margins remain below 40% through 2027. The divestitures support the efficiency narrative, but without clearer evidence of demand recovery and margin expansion, the risk/reward remains unattractive at current levels.

Implication

If within 12 months gross margin sustains above 42% and auto revenue grows high-single digits, consider adding; otherwise, the structural reset and valuation offer insufficient downside protection.

Thesis delta

The divestitures are a positive step for cost efficiency but do not alter the fundamental assessment that ON's recovery is fragile and valuation is stretched. The Fab Right strategy reduces costs but also signals deeper structural issues, leaving the WAIT rating intact.
