TD Cowen has moved onsemi's rating down one notch to Hold from Buy, citing the chipmaker's recently announced plan to buy Synaptics as a factor that complicates what had been a clearer growth story. The brokerage also reduced its 12-month price target to $110, from $115, pointing to a stock rally earlier this year that leaves less room for upside.
The deal, disclosed late on Thursday, is structured as an all-stock transaction. onsemi presented the acquisition as a way to broaden its footprint in artificial intelligence-driven intelligent systems and to bolster its position in emerging Physical AI applications.
TD Cowen said the Synaptics purchase does add strategic breadth to onsemi's portfolio, but it also dilutes the company's identity as a focused beneficiary of automotive electrification and datacenter power requirements. Management emphasized that the combination would expand the addressable market in Physical AI, yet the broker warned the transaction also introduces material exposure to consumer and wireless segments through Synaptics, which could complicate the investment narrative for shareholders.
According to TD Cowen, the acquisition brings complementary product lines and customer relationships, but the firm questioned whether Synaptics' edge AI processors are large enough in scope to position onsemi as a major rival to bigger, diversified semiconductor companies. The analyst team highlighted that management provided limited detail on revenue synergies beyond cross-selling opportunities between the two companies' offerings.
The deal includes a targeted $200 million in annual synergies, which TD Cowen says are expected to come mainly from reductions in operating expenses. However, the brokerage expressed a preference for clearer manufacturing-related cost savings that could more structurally improve gross margins. TD Cowen projects that meaningful earnings accretion will not occur until 2028 or 2029 and estimates the transaction would result in roughly 12% equity dilution for existing onsemi shareholders.
Beyond the strategic questions tied to the acquisition, TD Cowen noted near-term headwinds in onsemi's core operations. These include elevated inventory levels, the drag on growth from certain business exits, and a recovery in margins that depends on higher production volumes to cut underutilization costs. The brokerage also flagged pricing pressure in the company's power discrete product line, which constitutes about half of onsemi's sales.
On June 25, onsemi said it reached a definitive agreement to acquire Synaptics in an all-stock transaction that places Synaptics' enterprise value at about $7 billion. The companies said the deal is expected to close in mid-2027 and remains subject to shareholder and regulatory approvals. Alongside the announcement, onsemi reiterated its financial outlook for the second quarter of 2026.
For investors and market participants, the transaction reshapes the profile of a company that had been positioned around automotive electrification and datacenter power solutions. While management frames the acquisition as expanding capabilities in AI-enabled systems, TD Cowen's assessment emphasizes the trade-offs in product mix, timing of financial benefits, and potential dilution that market participants will need to weigh as the deal moves through approvals.
