The aggregate purchase price for all securities acquired by Samsara LP and Samsara Opportunity Fund in the May 2026 Offering was $2 million, which was funded by the working capital of each of Samsara LP and Samsara Opportunity Fund.

Rows 11 and 13 of each Reporting Person's cover page to this Schedule 13D/A set forth the aggregate number of shares of Class A common stock and percentages of the shares of Class A common stock beneficially owned by such Reporting Person and are incorporated by reference.

As of the date of the filing of this Schedule 13D/A, Dr. Akkaraju beneficially owns 9.99% of the outstanding Class A common stock. Due to field limitations of the EDGAR filing system, the percentage listed in Row 11 of Dr. Akkaraju's cover page has been rounded down to 9.9%.
