Investors Under Scrutiny: Pomerantz Law Firm's Investigation Into National Grid Plc

Investor Alert: Investigation into National Grid plc

The Pomerantz Law Firm has officially announced it is conducting investigations on behalf of investors of National Grid plc (NYSE: NGG). The firm is delving into crucial claims that the company may have engaged in securities fraud or other illegal business practices, particularly in light of a recent significant incident involving Heathrow Airport.

On July 1, 2025, the United Kingdom's energy system operator, National Energy System Operator (NESO), released a report concerning a devastating fire that occurred on March 20, 2025. This fire disrupted operations at Heathrow Airport, forcing it to shut down. The NESO report disclosed that the fire was triggered by a pre-existing fault at an electrical substation owned by National Grid. Alarmingly, National Grid was aware of this issue since 2018 yet failed to take corrective action. This negligence has raised serious concerns among investors and implications of potential legal action against National Grid by Heathrow Airport are now being reported in various media outlets.

Following the publication of the NESO report, National Grid's American Depositary Receipt (ADR) experienced a sharp decline in value, plummeting $3.77, or 5.07%, to close at $70.61 on July 2, 2025. This downturn reflects the immediate market response to the serious allegations surrounding the company's failure to act on critical security concerns.

Known for its rigorous defense of shareholders' rights, Pomerantz was founded by Abraham L. Pomerantz, whose legacy as a pioneer in the field of securities class actions continues today.
