On July 1, 2025, the United Kingdom’s energy system operator, National Energy System Operator (“NESO”), published a report summarizing the findings of its investigation into the March 20, 2025 fire that caused Heathrow Airport to shut down. NESO’s report stated that the fire was caused by a known fault at an electrical substation owned by National Grid, which had been aware of the problem since 2018 but failed to fix it. Media outlets subsequently reported that Heathrow Airport was considering legal action against National Grid. 

On this news, National Grid’s American Depositary Receipt (“ADR”) price fell $3.77 per ADR, or 5.07%, to close at $70.61 per ADR on July 2, 2025.
