• Continued actions by an activist shareholder have had, and may continue to have, a significant negative impact on our ability to execute our business strategies and have had, and may continue to have, an adverse affect on our results of operations and financial condition.
• Stockholders may be diluted significantly through our efforts to obtain financing, satisfy obligations through the issuance of securities or use our stock as consideration in certain transactions.
• A small number of stockholders, including our General Counsel and Secretary, own a significant amount of our common stock and may have influence over the Company.
• Our operations are subject to currency rate fluctuations.
• Adverse changes in actuarial assumptions used to calculate retirement plan costs due to economic or other factors, or lower returns on plan assets could adversely affect Barnwell’s results and financial condition.

Legal proceedings

On March 26, 2025, the Company commenced a lawsuit against the Sherwood Group in the Delaware Chancery Court, seeking, among other remedies, declaratory judgment that the Sherwood Group’s purported notice to nominate certain individuals for election to the Company’s board of directors at the 2025 Annual Meeting of stockholders was invalid and injunctive relief to enjoin the Sherwood Group from presenting its slate of nominees at the 2025 Annual Meeting due to the failure of the Sherwood Group to comply with the advance notice provisions of the Company’s Bylaws.

On April 21, 2025, the Sherwood Group filed an answer to the Company’s complaint, counterclaims against the Company and a third-party complaint against Alexander Kinzler, Kenneth Grossman and Joshua Horowitz in the Delaware Chancery Court, seeking, amongst other things, dismissal of all claims brought by the Company against the Sherwood Group, declaratory judgment that the Company’s directors breached their fiduciary duties, and injunctive relief to enjoin the Company from (i) applying the Company’s Bylaws to prevent the Sherwood Group from nominating its slate of nominees set forth in the defective Sherwood nomination notice for election at the 2025 Annual Meeting and (ii) filing or distributing further proxy solicitation materials for the 2025 Annual Meeting until the Delaware Chancery Court issued a ruling determining whether the Sherwood Group complied with the advance notice provisions of the Company’s Bylaws.
