The company can choose the anticipated effective date for corporate actions such as a name and ticker change as I understand it. The company may have picked a date in August as the Effective Date all along. We don't know for sure.
There is a place for it right on the FINRA paperwork.
2 FINRA forms are required for name and ticker change: 1 - The Transfer Agent Verification Form 2 - Issuer Company-Related Action Notification Form:
The Transfer Agent Verification Form is filled out by (you guessed it) the Transfer Agent, VStock Transfer LLC in our case.
Here is a filled-out Transfer Agent Verification Form as an example. Under the Name Change section it has a line for "Anticipated Effective Date for Corporate Action"
You can verify that this company did have a name change on their Anticipated Effective Date by looking them up on OTCmarkets and FINRA Daily List History.
Other supporting Documentation is required too, like the State Articles of Amendment for Name Change ect. We would have had to attach the WY SOS July 14 Name Change document on the FINRA EForm under the Documentation tab. That probably fell under a Request for Additional Information by FINRA.
