C3.ai Digital Transformation Institute Grants In February 2020, the Company entered into an agreement establishing the C3.ai Digital Transformation Institute (“C3.ai DTI”), a program established to attract many of the world’s leading research institutions to join in a coordinated and innovative effort to advance the digital transformation of business, government, and society. As part of the agreement, the Company has agreed to issue grants to C3.ai DTI, which are subject to compliance with certain obligations. The grants shall be paid by the Company over five years in the form of cash, publicly traded securities, or other property of equivalent net value. As of July 31, 2022 and April 30, 2022, the total potential remaining contributions are $31.6 million and $31.6 million, respectively. The future grant payments are conditional in nature and subject to execution of the program in line with specific requirements. Leases On August 25, 2021, the Company entered into a new lease to acquire approximately 283,015 square feet of office space in several phases in Redwood City, California. Total undiscounted base rent payments over the term of this lease are approximately $103.1 million. In addition to base rent, the Company will be responsible for the Company’s allocated share of costs incurred and expenditures made by the landlord in the operation and management of the leased space. Under the terms of the lease agreement, the Company has a rent abatement with respect to each phase for the initial six months following the rent commencement date for such phase, with initial monthly base rent payments expected to commence April 1, 2023, which will be approximately $0.5 million at commencement and will increase up to a maximum monthly base rent of approximately $1.0 million. The lease agreement also includes an aggregate tenant improvement allowance of $44.2 million for certain costs. The term of the lease is 126 months from the date that rent commences with respect to phase one of the leased space, which will be nine months after the date when phase one of the leased space is delivered to the Company. Pursuant to the lease agreement, the Company provided the landlord an unconditional and irrevocable letter of credit of $12.6 million, which is subject to reduction pursuant to the terms of the lease agreement. The lease commencement date of the first two phases was determined to have occurred in the quarter ended January 31, 2022, when the landlord delivered the leased space to the Company. The Company recorded $26.5 million of lease liability in other long-term liabilities and corresponding right-of-use asset in other assets, non-current in the condensed consolidated balance sheets. Legal Proceedings The Company is involved in various legal proceedings and periodically receives claims arising in the ordinary course of business. In the Company’s opinion, resolution of these matters is not expected to have a material adverse impact on its condensed consolidated statement of operations, cash flows, or balance sheet. Securities Litigation On March 4, 2022, a putative securities class action complaint (captioned The Reckstin Family Trust v. C3.ai, Inc. et al., 22-cv-01413-HSG) was filed in the U.S. District Court for the Northern District of California against the Company, and certain current and former officers and directors. The complaint generally alleges that the defendants made material misstatements or omissions about the Company’s partnership with Baker Hughes and other strategic alliances, the Company’s market potential, and the uptake of the Company’s products. The complaint alleges that defendants made these misstatements or omissions in connection with the Company’s initial public offering (“IPO”) in violation of Sections 11 and 15 of the Securities Act of 1933 and between December 9, 2020 and February 15, 2022, inclusive, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaint seeks unspecified damages, interest, fees and costs. Additionally, on May 23, 2022, a putative shareholder derivative action (captioned Suri v. Siebel et al., 22-cv-03031) was filed in the U.S. District Court for the Northern District of California. The plaintiff asserts claims on the Company’s behalf against certain of the Company’s officers and directors for breach of fiduciary duty, gross mismanagement, abuse of control, unjust enrichment, and contribution under the Securities Exchange Act of 1934 based on allegations similar to those in the securities class action. The Company is named as a nominal defendant. The derivative complaint seeks unspecified damages, an award of costs and expenses, including reasonable attorneys’ fees, and corporate governance reforms. The Company does not believe the claims have merit. As of the date of this report, the Company does not believe it is probable that these cases will result in an unfavorable outcome; however, if an unfavorable outcome were to occur in these cases, it is possible that the impact could be material to the Company's results of operations in the period(s) in which any such outcome becomes probable and estimable. In addition, from time to time, the Company is involved in various other legal proceedings arising in the ordinary course of business. Apart from the foregoing, the Company is not presently a party to any other such litigation the outcome of which, the Company believes, if determined adversely to the Company, would individually, or taken together, have a material adverse effect on the Company’s business, operating results, cash flows, or financial condition.
