Key questions

• How did the size of this sale compare to Heystee's historical sale activity?
  The 9,316 shares sold in this transaction is below the historical average sale size of approximately 16,938 shares, a reduction primarily attributable to diminished direct holdings after prior sales.
• What proportion of Heystee's stake was involved and what remains?
  The transaction accounted for roughly 21% of her direct ownership at the time, leaving a direct holding of 35,093 shares, which is approximately 0.06% of Ouster's outstanding shares as of the latest disclosure.
• Was there any use of indirect ownership vehicles or derivative securities in this trade?
  No; the entire transaction involved the direct sale of common stock, with no indirect holdings (such as trusts or LLCs) or derivative instruments (such as options) reported.
• How does the timing of this sale relate to Ouster's market performance?
  The sale was executed as the stock closed at $35.09 on May 21, 2026 — up 254.8% over the past year — suggesting Heystee continued to raise liquidity as the available direct share base declined, rather than signaling an outsized change in disposition strategy.

What this transaction means for investors

The May 21 sale of Ouster stock by Board of Directors member Susan Heystee does not appear to be a red flag for investors. Company shares soared in May, eventually hitting a 52-week high of $45.95 on May 27, just days after Heystee’s transaction.

Her disposition looks like she was capitalizing on the rising stock price to capture some gains. She still retained over 35,000 shares after the sale, suggesting she is not in a rush to dispose of her holdings.

Ouster stock surged after the company announced first quarter earnings on May 5. It reported record Q1 product revenue and 13 straight quarters of sales growth. Its Q1 revenue of $48.6 million represented a whopping 49% year-over-year increase.

The company’s success is thanks to the rise of artificial intelligence. Physical AI systems, such as self-driving cars and robots, benefit from Ouster’s lidar products.

As a result, it is likely to see ongoing revenue growth as AI adoption expands. In fact, Ouster predicts Q2 sales to accelerate to around $50 million. This means shareholders are wise to retain holdings to capture further upside, as it seems Heystee is doing.
