CV75/CV72 Edge AI SoC ramp • 2026-10-31

Base target: $68 / p=50% prob

Biggest risk

Gross margins declined year over year, GAAP losses continue, and Q3 margin guidance remains below prior-year levels. The Q2 beat and Q3 guide appear modest rather than transformational, while execution and demand durability remain unproven. Recent officer open-market sales may weigh on sentiment but do not establish operating deterioration.

Invalidation

Break below $52 or thesis failure.

What would change my mind?

Revenue growth, record Edge AI revenue, CV75/CV72 ramping, and commercial-vehicle momentum support a constructive operating trajectory. The Q3 revenue guide implies continued sequential growth. A multi-quarter shift toward advanced AI workloads could improve mix and ASPs.

Commentary

Post-earnings coverage was mixed but generally constructive: company results showed growth and management raised the sequential revenue baseline, while secondary coverage described a narrow beat and a matched Q3 sales outlook. The packet indicates the stock rose after the report, but no reliable magnitude or sustained-reaction data is available. Social, options, short-interest, and employee-sentiment data were unavailable; analyst revision evidence is also unavailable, so confidence remains moderate rather than high.

Risks

CEO, CFO, and other officers reported open-market share sales in June and July 2026; this is a sentiment risk but not direct evidence of weaker operations. [#SEC-FORM4-2026-07-02] [#SEC-FORM4-2026-06-18]
GAAP gross margin fell to 57.7% from 58.9% year over year, while non-GAAP gross margin fell to 59.3% from 60.5%. [#SEC-8K-2026-09-03]
No reliable post-earnings analyst target changes, estimate revisions, or detailed consensus data were available in the packet.
Q2 results included a non-recurring $9.0 million reduction in GAAP research-and-development expense related to release of a deposit liability, which limits comparability. [#SEC-8K-2026-09-03]
The Q3 outlook is seasonal and still carries execution risk around CV75/CV72 ramp timing, customer adoption, and automotive demand.

Peers
