[Form 4] Arteris, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Arteris, Inc. (AIP) Form 4 filing: 10% owner Bayview Legacy, LLC, managed by CEO K. Charles Janac, reported the sale of 50,000 common shares on 08/05/2025. The trade, executed under a Rule 10b5-1 plan adopted 03/05/2025, was coded “S” (open-market sale). Weighted-average price: $13.1199, with individual transactions between $12.35 and $14.20.

Following the sale, Bayview Legacy’s indirect beneficial ownership stands at 9,839,071 shares. No derivative transactions were reported. Janac has filed a separate Form 4 reflecting the same activity due to his control of the LLC.

The disposition represents roughly 0.5% of Bayview Legacy’s post-transaction holdings, leaving the insider with a substantial stake and signaling limited portfolio rebalancing rather than a material exit.

Positive

• Sale executed under a pre-disclosed Rule 10b5-1 plan, enhancing transparency and reducing potential insider-trading concerns.
• Insider retains 9.84 million shares, maintaining significant alignment with shareholder interests.

Negative

• 50,000 shares were sold by a 10% owner, which can be read as a modest bearish signal despite its small proportion of holdings.

Insights

Equity Analyst

TL;DR: Small 50k-share sale by 10% owner; negligible dilution, neutral impact.

The transaction equals about 0.5% of Bayview Legacy’s stake, suggesting routine liquidity rather than a directional view on AIP fundamentals. Execution under a pre-arranged 10b5-1 plan lowers the informational content of the trade, and the remaining 9.84 million shares continue to align insider interests with shareholders. I view the filing as neutral for valuation or near-term price action.

Corporate Governance Specialist

TL;DR: Transparent, plan-based sale supports governance best practices.

Use of a dated 10b5-1 trading plan and detailed price disclosure meet updated SEC guidance, reducing litigation risk and perception of opportunistic trading. With no derivative activity or board changes, governance posture remains intact. Insider still qualifies as 10% holder, so filing cadence should continue. Overall governance impact: neutral-to-positive.
