Applied Natural Gas Fuels Data Breach Exposes Sensitive Personal Information
Shamis & Gentile P.A., a class action law firm specializing in data breach cases, is investigating a cybersecurity incident involving Applied Natural Gas Fuels (Applied LNG), a leading producer and distributor of liquefied natural gas (LNG) and related fuels. The company, founded in 1995, serves transportation, industrial, and municipal sectors across the U.S. and Mexico, with production facilities in Topock, Arizona, and Midlothian, Texas, and headquarters in Westlake Village, California.
The breach was detected on or around December 22, 2025, prompting Applied LNG to initiate incident response protocols, secure affected systems, and launch an internal investigation. By February 20, 2026, the company confirmed that sensitive personally identifiable information (PII) may have been compromised. The incident was reported to the New Hampshire Attorney General on February 26, 2026, with at least one resident confirmed as affected.
Exposed data includes:
- Names
- Passport numbers
- Driver’s license numbers
- Social Security numbers
Applied LNG has begun notifying impacted individuals via first-class mail. Legal investigations are underway to determine eligibility for compensation under data breach laws, which may allow affected parties to seek damages for losses, time, and distress resulting from the incident.
