“It was a busy October for Liberty. We completed a transaction with Comcast which resulted in our repurchase of 6.3 million Liberty Media shares or 5.2% of our outstanding shares which takes total repurchases to over 51%,”
said Greg Maffei, President and CEO of Liberty Media. “We also reached an agreement with SiriusXM for them to repurchase $500 million of their shares from us.

Liberty Media
On January 11, 2013, Liberty Media was separated from Starz. Therefore, as of the first quarter of 2013 Liberty began presenting Starz as discontinued operations. Liberty acquired its controlling interest in SiriusXM on January 18, 2013 and has applied purchase accounting and consolidated the results of SiriusXM since that date. Prior to the acquisition of Liberty's controlling interest, we accounted for the investment in SiriusXM using the equity method.

Liberty Media's revenue increased $956 million to $1,110 million in the third quarter. Adjusted OIBDA increased by $350 million to $379 million and operating income increased $238 million to $248 million. The increase in revenue, adjusted OIBDA and operating income was primarily due to the acquisition of a controlling interest in SiriusXM as discussed above.

SiriusXM
SiriusXM reported its stand-alone third quarter results on October 24, 2013. For presentation purposes in this release, we include below the results of SiriusXM, as reported by SiriusXM, without regard to the purchase accounting adjustments applied by us for purposes of our financial statements. Liberty Media believes the presentation of financial results as reported by SiriusXM is useful to investors as the comparability of those results are best understood in the context of SiriusXM's historical financial presentation. For a reconciliation of revenue, adjusted OIBDA (as defined by Liberty Media) and operating income for SiriusXM's stand-alone operating results as reported by SiriusXM, to those results as reported by Liberty Media, see Liberty Media's Form 10-Q for the quarter ended September 30, 2013.

Highlights of SiriusXM's earnings release included the following:
Record revenue of $962 million, up 11% from third quarter of 2012
Net income of $63 million
Adjusted EBITDA grew 21% to a record $296 million
Repurchased $1.6 billion in shares from January 1 through September 30, 2013
Issued initial 2014 guidance; revenue of over $4.0 billion and Adjusted EBITDA of approximately $1.38 billion.

All such amounts are representative of SiriusXM's stand-alone operating results and are not indicative of what is included in Liberty Media's financial statements due to certain purchase accounting adjustments resulting from our January 18, 2013 acquisition of SiriusXM. SiriusXM is a separate publicly traded company and additional information about SiriusXM can be obtained through its website and filings with the Securities and Exchange Commission.

On October 9, 2013, Liberty entered into a share repurchase agreement with SiriusXM in which SiriusXM will acquire a to be determined number of shares for $500 million, in three separate tranches between the fourth quarter of 2013 and second quarter of 2014, at a purchase price to be determined based on a 1.5% discount to the average of the daily volume weighted average price (VWAP) per share of SiriusXM common stock over a period of ten days beginning

2



on the third trading day following the date of the public release of SiriusXM's third quarter 2013 earnings subject to a cap on the average VWAP of $4.18 and a floor on the average VWAP of $3.64. The repurchase of shares will approximate 1% of the outstanding shares of SiriusXM on an as adjusted basis as the shares will be retired at the SiriusXM level.  The purchase of SiriusXM shares on a consolidated basis is not expected to significantly impact the consolidated results except for an adjustment to noncontrolling interest as the shares are repurchased and retired.  Liberty expects to continue holding a majority of the SiriusXM common stock after the completion of share repurchases.

Share Repurchases
Liberty Media and Comcast completed a transaction in October in which a subsidiary of Comcast exchanged approximately 6.3 million LMCA shares at a price per share of $132.01 for a newly created subsidiary of Liberty Media which holds Leisure Arts, Inc., approximately $417 million in cash and Liberty Media's rights in and to a revenue sharing agreement relating to the carriage of CNBC. The exchange is intended to be tax-free.

From August 1, 2013 through October 31, 2013, 6.3 million shares of Series A Liberty Capital common stock (Nasdaq: LMCA) were acquired (pursuant to the transaction discussed above) at an average cost per share of $132.01 for total cash and other consideration of $830.2 million ($417 million cash, and negotiated fair values of Leisure Arts and Liberty Media's rights in and to a revenue sharing agreement related to the carriage of CNBC). After the completion of the Starz separation on January 11, 2013 through October 31, 2013, 7.4 million shares of Series A Liberty Capital common stock (Nasdaq: LMCA) were purchased at an average cost per share of $128.71 for total cash and other consideration of $953.2 million. Since the reclassification of the original Liberty Capital tracking stock on March 4, 2008 through October 31, 2013, 65.9 million shares have been repurchased at an average cost per share of $43.37 for total cash and other consideration of $2.9 billion. These repurchases represent 51.0% of the shares outstanding at the time of the introduction of the original Liberty Capital stock. Liberty Media has approximately $327.0 million remaining under its current stock repurchase authorization.

(4)
Includes margin loans, net of repayments, entered into during the quarter ended June 30, 2013 in connection with the Charter Communications investment.

Total Liberty Media cash and liquid investments increased $249 million, primarily as a result of cash flows from operations at SiriusXM during the quarter and net borrowings at Sirius XM during the quarter. These cash inflows were partially offset by repurchases of stock by SiriusXM. Included in the third quarter consolidated cash and liquid investments is $717 million at SiriusXM. Although SiriusXM is a consolidated subsidiary, it is a separate public company with a significant noncontrolling interest, therefore Liberty does not have ready access to that cash.

Total Liberty Media debt increased by $616 million primarily as a result of senior notes issued by SiriusXM during the quarter, net of other debt repayments. Subsequent to quarter end, SiriusXM used approximately $561 million of the cash raised, from the issuance of SiriusXM debt during the quarter, to retire approximately $490 million outstanding principal of SiriusXM's 7.625% Senior Secured Notes due 2018.

NON-GAAP FINANCIAL MEASURES

SCHEDULE 1

This press release includes a presentation of adjusted OIBDA, which is a non-GAAP financial measure, for Liberty Media, together with a reconciliation to operating income, as determined under GAAP. Liberty Media defines adjusted OIBDA as revenue less operating expenses, and selling, general and administrative expenses, excluding all stock based compensation, and excludes from that definition depreciation and amortization, restructuring and impairment charges and legal settlements that are included in the measurement of operating income pursuant to GAAP.

Liberty Media believes adjusted OIBDA is an important indicator of the operational strength and performance of its businesses, including each business' ability to service debt and fund capital expenditures. 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, Liberty Media 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 Liberty Media's management considers in assessing the results of operations and performance of its assets. Please see the attached schedules for applicable reconciliations.

The following table provides a reconciliation of adjusted OIBDA for Liberty Media to operating income calculated in accordance with GAAP for the three months ended September 30, 2012, December 31, 2012, March 31, 2013, June 30, 2013 and September 30, 2013, respectively.

SCHEDULE 2

This press release also includes a presentation of Adjusted EBITDA, which is a non-GAAP financial measure used by SiriusXM, together with a reconciliation to SiriusXM's stand-alone net income, as determined under GAAP. SiriusXM defines Adjusted EBITDA as follows: EBITDA is defined as net income before interest and investment income (loss); interest expense, net of amounts capitalized; income tax expense and depreciation and amortization. SiriusXM adjusts EBITDA to remove the impact of other income and expense, loss on extinguishment of debt as well as certain other charges discussed below. This measure is one of the primary non-GAAP financial measures on which SiriusXM (i) evaluates the performance of its businesses, (ii) bases its internal budgets and (iii) compensates management. Adjusted EBITDA is a non-GAAP financial performance measure that excludes (if applicable):  (i) certain adjustments as a result of the purchase price accounting for the merger of Sirius and XM, (ii) depreciation and amortization and (iii) share-based payment expense. The purchase price accounting adjustments include: (i) the elimination of deferred revenue associated with the investment in XM Canada, (ii) recognition of deferred subscriber revenues not recognized in purchase price accounting, and (iii) elimination of the benefit of deferred credits on executory contracts, which are primarily attributable to third party arrangements with an OEM and programming providers. SiriusXM believes adjusted EBITDA is a useful measure of the underlying trend of SiriusXM's operating performance, which provides useful information about its business apart from the costs associated with its physical plant, capital structure and purchase price accounting. SiriusXM believes investors find this non-GAAP financial measure useful when analyzing its results

and comparing its operating performance to the performance of other communications, entertainment and media companies. SiriusXM believes investors use current and projected adjusted EBITDA to estimate its current and prospective enterprise value and to make investment decisions. Because SiriusXM funds and builds-out its satellite radio system through the periodic raising and expenditure of large amounts of capital, its results of operations reflect significant charges for depreciation expense. The exclusion of depreciation and amortization expense is useful given significant variation in depreciation and amortization expense that can result from the potential variations in estimated useful lives, all of which can vary widely across different industries or among companies within the same industry. SiriusXM also believes the exclusion of share-based payment expense is useful given the significant variation in expense that can result from changes in the fair value as determined using the Black-Scholes-Merton model which varies based on assumptions used for the expected life, expected stock price volatility and risk-free interest rates.
        
Adjusted EBITDA has certain limitations in that it does not take into account the impact to SiriusXM's statements of comprehensive income of certain expenses, including share-based payment expense and certain purchase price accounting for the merger of Sirius and XM. SiriusXM endeavors to compensate for the limitations of the non-GAAP measure presented by also providing the comparable GAAP measure with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the Non-GAAP measure.  Investors that wish to compare and evaluate SiriusXM's operating results after giving effect for these costs, should refer to net income as disclosed in its consolidated statements of comprehensive income. Since adjusted EBITDA is a non-GAAP financial performance measure, SiriusXM's calculation of adjusted EBITDA may be susceptible to varying calculations; may not be comparable to other similarly titled measures of other companies; and should not be considered in isolation, as a substitute for, or superior to measures of financial performance prepared in accordance with GAAP. The reconciliation of SiriusXM's stand-alone net income to adjusted EBITDA is calculated as follows (in thousands):
