Why did $NVDA release preliminary earnings report and official report is only 2 weeks away?

Hello,

Today, $NVDA released preliminary earnings report which was disappointing and it was expected, IMO. However, why did Nvidia not wait until Aug 24th for official report? Is there any reason, you can think of, that made Nvidia release preliminary earnings report just 2 weeks before official ER?

I like Nvidia, but I think it is currently overpriced, especially when Fed is hiking rates.
