- How did this transaction impact Antonio Viana's ownership structure?
Direct holdings declined to 4,704 shares, while indirect holdings via Viana Family Trust now total 64,620 shares, leaving Viana with a combined 69,324 shares post-transaction, or approximately 1.4% of his position at the start of the recent period. - What proportion of Viana's available shares was sold in this event?
This filing represents a disposition of 23.11% of total pre-transaction holdings, reducing Viana's direct holdings to 4,704 shares and indirect holdings to 64,620 shares. - Was this a routine disposition or a deviation from historical trade size?
Recent sale sizes, including this 20,839-share transaction, fall within the typical range for Viana's prior open-market sales, but reflect a shrinking base: the average sell-only trade in the past year was ~14,700 shares, and the diminished available holdings now cap future trade size. - Did the transaction timing align with market conditions?
Shares were sold at a weighted average price around $36.51, close to the June 4, 2026 closing price of $37.19, occurring during a period in which Arteris shares delivered a 332.28% one-year total return as of the transaction date.

What this transaction means for investors
The June 4 sale of Arteris stock by Board of Directors member Antonio Viana came at a time when shares were skyrocketing. They reached a 52-week high of $38.99 a day before Viana’s disposition.
This transaction involved moving 20,839 directly-held shares into the Viana Family Trust, then selling those shares from there. Although the sale happened when Arteris stock was rising, the move was a non-discretionary transaction.
It was executed as part of a pre-arranged Rule 10b5-1 trading plan, adopted in June of 2025. Such plans are often implemented by insiders to avoid accusations of trading based on insider information. Consequently, Viana’s sale is not a cause for investor concern.
Arteris stock is doing well thanks to strong business performance. The company reported revenue of $22.9 million in the first quarter, representing 39% year-over-year growth. Sales are soaring due to customer demand from across multiple sectors, including aerospace and defense, and artificial intelligence.
