Regulation FD Disclosure regulatory

"Item 7.01Regulation FD Disclosure. On June 11, 2026, the Registrant posted an updated investor presentation"

Regulation FD disclosure requires public companies to share important, market-moving information with everyone at the same time instead of tipping off analysts or large investors first. Think of it as making sure all players on a field hear the same announcement simultaneously; that fairness helps investors trust that stock prices reflect the same information and reduces the risk of sudden, unfair trading advantages or regulatory penalties for selective leaks.
