On September 29, 2022, the board of directors of Warner Music Group Corp. approved a change, effective for the 2023 fiscal year, from a modified 52/53-week reporting calendar, in which reporting periods ended on the last Friday of the calendar quarter, to a reporting calendar in which the reporting periods end on the last day of the calendar quarter. The company's fiscal year will begin on October 1 and end on September 30.

The company is not required to file a transition report because this change is not deemed to be a change in fiscal year for purposes of reporting under the Securities Exchange Act of 1934, as amended, pursuant to relevant Securities and Exchange Commission guidance.
