NET Power Inc

Our corporate offices are in Durham, North Carolina, where we lease approximately 12,000 square feet under a lease that expires in December 2028, and in Houston, Texas, where we lease approximately 9,800 square foot under a lease that commenced in July 2024. The Houston office lease has an initial lease term of 68 months with an option to extend the term for an additional five years. Most of the facilities are used for our research and development and corporate operations.

Our Demonstration Plant is in La Porte, Texas, where we lease approximately 218,900 square feet of land from Air Liquide under a lease that expires on the earlier of (i) January 31, 2031 and (ii) the termination of our oxygen supply agreement with Air Liquide, pursuant to which Air Liquide supplies oxygen for our use at the Demonstration Plant. The term of the oxygen supply agreement is perpetual but may be terminated by us or by Air Liquide upon 30 days’ written notice.

We believe these facilities are adequate to meet our current needs. However, in order to accommodate anticipated growth, we may need to seek additional facilities.
