The April 17 sale of 30,000 Ouster shares by its CTO Mark Frichtl is not a warning sign for investors. Frichtl sold the stock under a Rule 10b5-1 trading plan adopted in December of 2025. Such plans are often implemented by executives to avoid accusations of making trades based on insider information.
In addition, Frichtl retained over 700,000 shares after the transaction, and possesses nearly 200,000 stock options that can be exercised after vesting. This shows he continues to maintain a substantial stake in the company.
Ouster shares are up significantly from the 52-week low of $6.58 reached in April of 2025, but are quite volatile as evidenced by the beta of nearly three. Its sales are skyrocketing, with 2025 revenue growing 52% to $169 million compared to 2024. This is why its stock price increased.
Despite the massive sales growth, the company is not profitable. It exited 2025 with a net loss of $60.4 million. But because the share price is up, Ouster’s price-to-sales ratio of eight is about double what it was a year ago, suggesting its stock valuation is elevated, and contributing to the volatility.
Given Ouster’s sales multiple, now is a good time to sell shares as Frichtl has done, but for investors looking to buy, wait for the price to dip first.
