OPPORTUNE LLP DATA BREACH: Edelson Lechtzin LLP Launches Investigation Into Exposure of Social Security Numbers

National class action firm Edelson Lechtzin LLP is offering free case evaluations to individuals affected by the Opportune LLP data breach, which may have exposed names, Social Security numbers, and financial account, credit, or debit card information.

HOUSTON, Sept. 24, 2026 /PRNewswire/ -- Edelson Lechtzin LLP, a national class action law firm, is investigating data privacy claims arising from the Opportune LLP data breach. Opportune LLP is a Houston-based global business advisory and consulting firm that provides outsourced accounting services to the oil and gas industry, including the processing of royalty interest owner payments. The affected data belongs to individuals who receive, or previously received, royalty payments related to Phillips 66.

Key Facts at a Glance

• Company: Opportune LLP — a global business advisory and consulting firm headquartered in Houston, Texas, serving the energy sector.
• When it happened: The breach reportedly occurred on or around June 22, 2026, and was discovered on August 18, 2026.
• When disclosed: Opportune began mailing notification letters in September 2026 and filed notices in California, Massachusetts, and Vermont.
• People affected: More than 32,000 Texas residents, plus 322 Massachusetts and 56 Vermont residents (378 combined in those two states), with additional individuals potentially affected nationwide.
• Information exposed: Names, Social Security numbers, and financial information, including account numbers and credit or debit card numbers.

What Happened

Opportune LLP experienced a data security incident that may have compromised personal information it holds while providing royalty payment and accounting services. Notice letters were sent through Cyberscout. Importantly, Phillips 66's own systems are not alleged to have been breached; Opportune received the data in the course of its services.

What Information Was Exposed

The breach may have compromised:

• Names
• Social Security numbers
• Financial information, including account numbers and credit or debit card numbers

Because Social Security numbers and financial account details are highly sensitive, affected individuals face an increased and lasting risk of identity theft, fraudulent account creation, tax fraud, and targeted phishing.

Your Legal Options

Edelson Lechtzin LLP is investigating a potential class action to pursue legal remedies for individuals whose sensitive personal data may have been compromised. The firm is examining whether Opportune LLP implemented reasonable cybersecurity safeguards and whether additional measures could have prevented or reduced the breach's impact. The firm will evaluate your rights and potential claims at no cost.

Recommended Protective Steps

• Preserve your breach notification letter and enroll in the complimentary credit monitoring offered through Cyberscout before the stated deadline.
• Monitor your account statements and credit reports for unauthorized activity.
• Consider placing a fraud alert or security freeze with Equifax, Experian, and TransUnion.
• Be cautious of phishing calls, texts, and emails referencing the breach, and change passwords on affected accounts.
• Remember your rights under the federal Fair Credit Reporting Act, including a free credit report and the right to dispute inaccurate information.
