Intuitive Machines CEO Stephen Altemus sold 13,751 shares of the company's stock on April 15th, 2026 for a total transaction value of $324,661. The sale was made to cover tax withholding obligations related to the vesting of Altemus' equity awards. Following the sale, Altemus still directly owns over 1.1 million shares in the Houston-based aerospace firm, which specializes in commercial lunar exploration and services.

Why it matters

Insider stock sales can provide insight into executive sentiment and the overall health of a company. While Altemus' sale represents a relatively small portion of his overall stake, it may signal that he is taking some chips off the table after a period of strong stock performance for Intuitive Machines.

The details

Altemus sold the 13,751 shares at an average price of $23.61 per share. This transaction reduced his direct ownership stake in Intuitive Machines by 1.17%. The company's stock has seen significant gains over the past year, rising from a low of $6.75 to a high of $28.22 as of Friday's close.

  • The stock sale took place on Wednesday, April 15th, 2026.
  • Intuitive Machines' stock opened at $27.58 on Friday, April 18th, 2026.
