Schall, Brown & Schwartz LLP said it is investigating Noble Corporation plc on behalf of investors over potential securities law violations following the company's second-quarter 2026 results. The firm said the review is centered on whether Noble issued false or misleading statements or failed to disclose material information to investors. Noble reported on July 27, 2026 that its second quarter was hurt by $43 million because both of its rigs in Brazil were operationally suspended, and it also lowered its full-year 2026 EBITDA guidance. Shares fell by almost 9.1% on July 28, 2026 after that update. The press release also invited shareholders who suffered losses to contact the firm and said the notice may be considered Attorney Advertising in some jurisdictions.
