EliteSiC M4 Advances SiC Roadmap, But Cyclical Headwinds Persist

What happened

onsemi introduced its fourth-generation silicon carbide platform, EliteSiC M4, promising up to 30% higher power density and 35% lower losses than the prior generation, targeting AI data centers, electric vehicles, and energy infrastructure. This product launch aligns with onsemi's strategic emphasis on SiC and wide-bandgap power as a key growth driver, as detailed in the company's long-term targets and recent acquisitions. However, the announcement comes amid a cyclical downturn: automotive and industrial demand remain weak, gross margins are compressed to ~38%, and fab utilization is only ~74%, far from levels needed for the targeted margin recovery. While the new technology may strengthen competitive positioning against peers like STMicro and Infineon, it does not address near-term revenue declines or the risk of LTSA amendments that have already weakened backlog quality. Therefore, the news is incrementally positive for the long-term SiC franchise, but it is unlikely to change the near-term financial trajectory or valuation concerns that underpin the current WAIT rating.

Implication

The product announcement demonstrates onsemi's continued innovation in silicon carbide, which could eventually help capture share in high-growth AI and EV power markets. However, meaningful revenue contribution from M4 is likely 12-18 months away, and design wins must be converted into orders against strong competition. Near-term, automotive and industrial end markets are still weak, and the company's gross margin recovery hinges on higher fab utilization and favorable mix, which are not directly impacted by a new product launch. The $6 billion buyback authorization remains a double-edged sword: it may support EPS but could stretch the balance sheet if free cash flow stays subdued. Until there is concrete evidence of demand recovery and margin expansion, the stock's ~77x trailing P/E leaves limited margin of safety, and we maintain a wait-and-see approach with an attractive entry near $50.

Thesis delta

The launch of EliteSiC M4 slightly strengthens onsemi's long-term competitive positioning in silicon carbide, but it does not alter near-term cyclical or valuation concerns. Our WAIT rating is unchanged; we will monitor design win traction and revenue conversion, but for now the product announcement is not enough to adjust our $50 attractive entry or $75 trim point.
