MDB Capital Holdings LLC

We own no real property. Our principal office is located in Addison, Texas. In July 2022, we secured a lease for approximately 5,500 square feet of office space, with the lease set to expire in July 2030. This space serves as our principal executive offices and for general office use. The base monthly rental rate is $12,556 until July 2024, after which it will increase to $12,786. Subsequent increases are scheduled as follows: to $13,016 in July 2025, $13,246 in July 2026, $13,476 in July 2027, $13,707 in July 2028, and finally, to $13,937 in July 2029, continuing through the end of the lease term in July 2030. During the year ended December 31, 2022, the Company utilized short-term office space of 1,300 square feet provided by the controlling member of the Company at a monthly charge of $1,600.

Additionally, we lease office and laboratory space across two suites in Monrovia, California. Following a modification to both leases on October 30, 2023, we now occupy approximately 9,800 square feet under a lease expiring in June 2029. The current base monthly rental rate is $27,648 until July 2024, set to increase to $28,405. Further increases are planned: to $29,184 in July 2025, $29,983 in July 2026, $30,806 in July 2027, and to $31,650 in July 2028, which will remain in effect until the lease concludes in June 2029.

We believe that each of our leased spaces is at local market rates, and there is sufficient space available in each location to permit the specific operations to obtain additional or other space if and when required. We do not believe that if there is additional space or other space required, that the cost will be prohibitive.
