What this transaction means for investors
10x Genomics CEO Serge Saxonov’s May 22 and May 26 sale of company stock is not a red flag for investors. The May 22 disposition involving 18,175 shares was executed to cover tax withholding obligations related to the vesting of restricted stock units.
As for the May 26 sale of 10,718 shares, it was implemented as part of a Rule 10b5-1 trading plan, adopted in November of 2025. Such pre-arranged trading plans are often implemented by insiders to avoid accusations of making trades based on insider information.
The May 26 transaction occurred at a time when 10x Genomics shares were soaring. They eventually hit a 52-week high of $28.86 on May 29, just days after Saxonov’s disposition. Still, he retained over one million directly-held shares after the transaction, indicating that his stake in the company remains plentiful.
Although 10x Genomics revenue in the first quarter fell 3% year over year to $150.8 million, the company’s stock is up because it managed costs well, reducing its Q1 net loss to $13.5 million compared to a loss of $34.4 million in the prior year.
