NON-GAAP FINANCIAL MEASURES
To provide investors with additional information regarding our financial results, this press release includes a presentation of adjusted OIBDA, which is a non-GAAP financial measure, for Qurate Retail, QVC (and certain of its subsidiaries), Zulily (through May 23, 2023) and Cornerstone together with a reconciliation to that entity or such businesses’ operating income, as determined under GAAP. Qurate Retail defines adjusted OIBDA as operating income (loss) plus depreciation and amortization, stock-based compensation, and where applicable, separately identified impairments, litigation settlements, restructuring, acquisition-related costs, fire related costs, net (including Rocky Mount inventory losses), and (gains) losses on sale leaseback transactions. Further, this press release includes adjusted OIBDA margin, which is also a non-GAAP financial measure. Qurate Retail defines adjusted OIBDA margin as adjusted OIBDA divided by revenue.
Qurate Retail believes adjusted OIBDA is an important indicator of the operational strength and performance of its businesses by identifying those items that are not directly a reflection of each business’s performance or indicative of ongoing business trends. In addition, this measure allows management to view operating results and perform analytical comparisons and benchmarking between businesses and identify strategies to improve performance. Because adjusted OIBDA is used as a measure of operating performance, Qurate Retail views operating income as the most directly comparable GAAP measure. Adjusted OIBDA is not meant to replace or supersede operating income or any other GAAP measure, but rather to supplement such GAAP measures in order to present investors with the same information that Qurate Retail's management considers in assessing the results of operations and performance of its assets. Please see the attached schedules for applicable reconciliations.
In addition, this press release includes references to adjusted net income and adjusted earnings per share, which are non-GAAP financial measures, for Qurate Retail. Qurate Retail defines adjusted net income as net income, excluding the impact of acquisition accounting amortization (net of deferred tax benefit), mark-to-market adjustments on certain public debt and equity securities, (gain) loss on sale of fixed assets and other one-time adjustments. Qurate Retail defines adjusted earnings per share as diluted earnings per share plus the diluted per share effects of certain adjustments, net of tax.
