SiriusXM Reports Third Quarter 2013 Results

NEW YORK – October 24, 2013 – Sirius XM Radio (NASDAQ: SIRI) today announced third quarter 2013 financial and operating results, including record revenue of $962 million, up 11% from the third quarter 2012 revenue of $867 million. Net income for the third quarter of 2013 and 2012 was $63 million and $75 million, respectively, including losses on extinguishment of debt of $108 million and $107 million, respectively. Earnings per fully-diluted share were $0.01 each in the third quarter of 2013 and 2012.

Income before income taxes was $124 million in the third quarter 2013, an increase of 128% from $54 million in the third quarter of 2012. Adjusted EBITDA for the third quarter of 2013 reached a record $296 million, up 21% from $245 million in the third quarter of 2012.

“SiriusXM had a great quarter, with the 513,000 net subscriber additions and the 373,000 self-pay net additions setting post-merger records for the third quarter. We also saw double-digit growth in revenue for the seventh consecutive quarter, a new quarterly record for adjusted EBITDA and adjusted EBITDA margin, and significant growth in free cash flow. With continued growth in new automobile sales and an increasing number of existing self-pay subscribers selling their cars and rotating back into our trial funnel, we are increasing our guidance for net subscriber additions and reducing our guidance for self pay subscriber additions by equal amounts. We are also pleased to increase revenue guidance for 2013 and introduce new guidance for continued growth in 2014 in both revenue and adjusted EBITDA,” noted Jim Meyer, Chief Executive Officer, SiriusXM.

“We are proud of all we accomplished in the third quarter: strong operating results, significant improvements in our balance sheet, renewals of important long-term programming contracts, and the announced acquisition of the connected vehicle unit of Agero,” added Meyer.

Additional highlights of the third quarter include:

“We have taken significant steps over the past year to improve our balance sheet, lowering our average cost of debt from 9.2% last summer to just 5.5% following the redemption of the 7.625% Senior Notes due 2018. The new debt we have issued gives our Company greater flexibility to pursue capital returns and other strategic opportunities,” said David Frear, SiriusXM’s Executive Vice President and Chief Financial Officer.

“During the third quarter, we repurchased approximately 124 million shares of our common stock for $459 million, bringing our year-to-date purchases to approximately 477 million shares for approximately $1.6 billion. We have approximately $2.4 billion remaining under our recently increased share repurchase authorization, and we anticipate using $500 million of this authorization to repurchase shares directly from Liberty Media in three installments beginning next month. At the end of the third quarter, and pro forma for the announced redemption of the 7.625% Senior Notes due 2018, our outstanding debt was a very conservative 3.0x trailing adjusted EBITDA,” added Frear.

2013 AND 2014 GUIDANCE

The Company today increased its expectation for 2013 total net subscriber growth and revenue, reduced its estimate for 2013 self-pay net subscriber growth, and reiterated its existing guidance for adjusted EBITDA and free cash flow.

The Company also provided initial guidance for 2014 revenue and adjusted EBITDA:

Subscriber Data and Operating Metrics

The following table contains subscriber data and key operating metrics for the three and nine months ended September 30, 2013 and 2012, respectively:  

Glossary

Adjusted EBITDA - 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. We adjust 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 we (i) evaluate the performance of our businesses, (ii) base our internal budgets and (iii) compensate 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. We believe adjusted EBITDA is a useful measure of the underlying trend of our operating performance, which provides useful information about our business apart from the costs associated with our physical plant, capital structure and purchase price accounting. We believe investors find this Non-GAAP financial measure useful when analyzing our results and comparing our operating performance to the performance of other communications, entertainment and media companies. We believe investors use current and projected adjusted EBITDA to estimate our current and prospective enterprise value and to make investment decisions. Because we fund and build-out our satellite radio system through the periodic raising and expenditure of large amounts of capital, our 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. We also believe 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 our statements of comprehensive income of certain expenses, including share-based payment expense and certain purchase price accounting for the merger of Sirius and XM. We endeavor 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 our operating results after giving effect for these costs, should refer to net income as disclosed in our consolidated statements of comprehensive income. Since adjusted EBITDA is a Non-GAAP financial performance measure, our 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 net income to the adjusted EBITDA is calculated as follows (in thousands):

Adjusted Revenues and Operating Expenses - We define this Non-GAAP financial measure as our actual revenues and operating expenses adjusted to exclude the impact of certain purchase price accounting adjustments and share-based payment expense. We use this Non-GAAP financial measure to manage our business, set operational goals and as a basis for determining performance-based compensation for our employees. The following tables reconcile our actual revenues and operating expenses to our adjusted revenues and operating expenses for the three and nine months ended September 30, 2013 and 2012:

(a) Purchase price accounting adjustments included above exclude the incremental depreciation and amortization associated with the $785,000 stepped up basis in property, equipment and intangible assets as a result of the merger of Sirius and XM. The increased depreciation and amortization for the three months ended September 30, 2013 was $12,000.

(a) Purchase price accounting adjustments included above exclude the incremental depreciation and amortization associated with the $785,000 stepped up basis in property, equipment and intangible assets as a result of the merger of Sirius and XM. The increased depreciation and amortization for the three months ended September 30, 2012 was $13,000.

(a) Purchase price accounting adjustments included above exclude the incremental depreciation and amortization associated with the $785,000 stepped up basis in property, equipment and intangible assets as a result of the merger of Sirius and XM. The increased depreciation and amortization for the nine months ended September 30, 2013 was $37,000.

(a) Purchase price accounting adjustments included above exclude the incremental depreciation and amortization associated with the $785,000 stepped up basis in property, equipment and intangible assets as a result of the merger of Sirius and XM. The increased depreciation and amortization for the nine months ended September 30, 2012 was $41,000.

ARPU - is derived from total earned subscriber revenue, advertising revenue and other subscription-related revenue, net of purchase price accounting adjustments, divided by the

number of months in the period, divided by the daily weighted average number of subscribers for the period. Other subscription-related revenue includes the U.S. Music Royalty Fee. Purchase price accounting adjustments include the recognition of deferred subscriber revenues not recognized in purchase price accounting associated with the merger of Sirius and XM. ARPU is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

Average self-pay monthly churn - is defined as the monthly average of self-pay deactivations for the period divided by the average number of self-pay subscribers for the period.

Customer service and billing expenses, per average subscriber - is derived from total customer service and billing expenses, excluding share-based payment expense, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. We believe the exclusion of share-based payment expense in our calculation of customer service and billing expenses, per average subscriber, is useful given the significant variation in expense that can result from changes in the fair market value of our common stock, the effect of which is unrelated to the operational conditions that give rise to variations in the components of our customer service and billing expenses. Customer service and billing expenses, per average subscriber, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

Free cash flow - is derived from cash flow provided by operating activities, capital expenditures and restricted and other investment activity. The calculations for free cash flow and free cash flow per fully-diluted share are as follows (in thousands, except per share data):

New vehicle consumer conversion rate - is defined as the percentage of owners and lessees of new vehicles that receive our service and convert to become self-paying subscribers after the initial promotion period. At the time satellite radio enabled vehicles are sold or leased, the owners or lessees generally receive trial subscriptions ranging from three to twelve months. Promotional periods generally include the period of trial service plus 30 days to handle the receipt and processing of payments. We measure conversion rate three months after the period in which the trial service ends. The metric excludes rental and fleet vehicles.

Subscriber acquisition cost, per gross subscriber addition - or SAC, per gross subscriber addition, is derived from subscriber acquisition costs and margins from the sale of radios and accessories, excluding purchase price accounting adjustments, divided by the number of gross subscriber additions for the period. Purchase price accounting adjustments associated with the merger of Sirius and XM include the elimination of the benefit of amortization of deferred credits on executory contracts recognized at the merger date attributable to an OEM. SAC, per gross subscriber addition, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):
