NOTES

[A]	WarnerMedia segment results as reported in AT&T's consolidated financial statements, including Otter, Xandr and Playdemic.
[B]	Vrio business unit results within the Latin America segment as reported in AT&T's consolidated statements. AT&T retained the investment in Sky Mexico.
[C]	Adjustments for impacts from receivable securitizations related to WarnerMedia and the recharacterization of programming intangible assets amortization for released programming acquired in the Time Warner acquisition, which we continued to report with the WarnerMedia segment operating expenses.
[D]	Adjustments for AT&T's retention of the addressable TV advertising business, Invidi, and historically allocated general corporate overhead costs that do not meet the requirements for presentation in discontinued operations.
[E]	Video business results as reported in AT&T's consolidated financial results; quarters ended 2021 include retained depreciation on assets supporting U-verse products.
[F]	Other dispositions include the held-for-sale businesses, Crunchyroll, Government Solutions and operations in Puerto Rico that do not meet the requirements for presentation in discontinued operations.
[G]	After the DIRECTV transaction, we expect to retain incurred operations and support costs in the range of ~$500M per quarter and depreciation of network infrastructure that provides both U-verse video and broadband services to customers of ~$150M per quarter, of which approximately 60% will be received from DIRECTV through transition service agreements and commercial arrangements. These estimated net retained costs have been applied to prior periods for comparability.
[H]	Estimated equity in net income of affiliates from DIRECTV. Calculated at 70% of Video EBITDA, which excludes the noncash depreciation and amortization of fair value accretion expected to result from DIRECTV’s revaluation of assets and purchase price allocation.
[I]	Reflects the use of proceeds to pay down approximately $39.0 billion of borrowings and the resulting reduction to interest expense. The estimated impact of interest expense reduction was determined using the weighted-average interest rate of AT&T’s long-term debt portfolio, including credit agreement borrowings and the impact of derivatives, of 3.8%. As of the date of the filing to which these unaudited pro forma financial statements are attached, the Company has committed to approximately $10.1 billion of term loan repayments with a weighted-average rate of 1.1% and make-whole or other redemptions totaling $9.3 billion with a weighted-average rate of 3.5%. This adjustment is required for forma financial information prepared in accordance with Article 11 of Regulation S-X.
[J]	Estimated tax impact of pro forma and other adjustments at AT&T's adjusted effective tax rate of 20.0% for the year ended December 31, 2021, and 19.6% for the year ended December 31, 2020.
[K]	Under GAAP, AT&T removed transactions involving dealing between segments, including channel distribution of WarnerMedia content, and advertising arrangements.

1 As reported in AT&T’s Form 8-K filed April 22, 2021, July 23, 2021, October 21, 2021 and January 26, 2022, recast for consistency to include gains on benefit-related and other cost investments as noted above. Adjusting items include items considered non-operational or non-recurring in nature, including dispositions and merger integration and transaction costs, actuarial gains and losses, significant abandonments and impairments, severance and other material gains and losses.

2 Includes adjustments to equity in net income of affiliates, including adjustment for DIRECTV intangible amortization (proportionate share).

[M] Adjustment to reflect AT&T's first-quarter 2022 reclassification of certain administrative costs born by AT&T where the business units did not influence decision making. These costs are not expected to continue in standalone AT&T.
