EXPLANATORY NOTE

On February 7, 2024, Warner Music Group Corp. (the "Company") filed a Current Report on Form 8-K(the "Original Form 8-K")to report, among other things, a strategic restructuring plan (the "Plan") designed to free up more funds to invest in music and accelerate the Company's growth for the next decade. The Company is now filing this Amendment No.1 to the Original Form 8-Kin order to amend and supplement the Company's disclosure under Item 2.05 of the Original Form 8-K.The Original Form 8-Kotherwise remains unchanged.

ITEM 2.05

COST ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES.

Plan Estimates in Original Form 8-K

As disclosed in the Original Form 8-K,the Company expected the Plan to generate pre-taxcost savings of approximately $200 million on an annualized run-ratebasis by the end of fiscal year 2025 and for the Company to incur total non-recurringpre-taxcharges of approximately $140 million or approximately $105 million of total non-recurringafter-taxcharges. The expected pre-taxcharges included approximately $85 million of severance payments and other related termination costs and approximately $55 million of non-cashimpairment charges primarily in connection with the disposal or winding down of the Company's non-coreowned and operated media properties including the Company's in-houseadvertising sales function (the "O&O Media Properties"). The Plan anticipated a reduction in headcount of approximately 600 or 10%, a majority of which were expected to be related to the O&O Media Properties, Corporate and various support functions.

As disclosed in the Original Form 8-K,the Company expected the majority of the charges associated with the Plan - approximately $120 million of total non-recurringpre-taxcharges or approximately $90 million of total after-taxcharges - to be incurred by the end of fiscal year 2024. The anticipated pre-taxcharges included approximately $65 million in severance payments and other termination related costs and approximately $55 million in non-cashimpairment charges primarily in connection with the disposal or winding down of the O&O Media Properties. The approximately $65 million of severance payments and other termination related costs were expected to be paid by the end of fiscal year 2025, with approximately $35 million of those payments and costs expected to be paid by the end of fiscal year 2024.

Revised Plan Estimates

As a result of ongoing implementation and evaluation of the Plan, the Company has revised certain estimates that were previously disclosed in the Original Form 8-K.The Company now expects the Plan to generate pre-taxcost savings of approximately $260 million, a significant majority of which will be achieved by the end of fiscal year 2025, and for the Company to incur total non-recurringpre-taxcharges of approximately $210 million or approximately $135 million of total non-recurringafter-tax charges. The now expected pre-taxcharges include approximately $150 million of severance payments and other termination costs and $5 million of other non-cashcharges, along with the unchanged amount of approximately $55 million of non-cashimpairment charges primarily in connection with the disposal or winding down of the O&O Media Properties. The Company now anticipates a reduction in headcount of approximately 750 or 13%, a majority of which are still expected to be related to the O&O Media Properties, Corporate and various support functions.

The Company still expects the majority of the charges associated with the Plan - approximately $180 million of total pre-taxcharges or approximately $115 million of total after-taxcharges - to be incurred by the end of fiscal year 2024. The anticipated pre-taxcharges in fiscal year 2024 are now expected to include approximately $125 million in severance payments and other termination costs and approximately $50 million in non-cashimpairment charges primarily in connection with the disposal or winding down of the O&O Media Properties and $5 million of other non-cashcharges. The significant majority of the approximately $150 million of severance payments and other termination costs are now expected to be paid by the end of fiscal year 2026, with approximately $30 million of those payments and costs now expected to be paid in fiscal year 2024 and approximately $85 million of those payments and costs now expected to be paid in fiscal year 2025.

The Company's implementation and evaluation of the Plan are ongoing and could result in additional charges above the revised estimates.

This Item 2.05 contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements related to expected costs and expected cost savings. These forward-looking statements are based on the Company's current expectations and inherently involve significant risks and uncertainties. The Company's actual results and the timing of events, including the expected

completion timing of the Plan, could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, risks related to cost reduction efforts. In addition, the Company's restructuring costs may be greater than anticipated and the headcount reductions may have an adverse impact on the Company's business. Investors should not rely on forward-looking statements because they are subject to a variety of risks, uncertainties, and other factors that could cause actual results to differ materially from the Company's expectations. Please refer to the Company's Form 10-K,Form 10-Qsand other filings with the U.S. Securities and Exchange Commission concerning factors that could cause actual results to differ materially from those described in the Company's forward-looking statements.
