SiriusXM Reports Fourth Quarter and Full-Year 2014 Results

NEW YORK – February 5, 2015 – SiriusXM today announced fourth quarter and full-year 2014 operating and financial results, including record revenue of $1.09 billion and $4.18 billion for the fourth quarter and full-year, respectively, up 9% and 10% versus the prior year periods.

Net income of $143 million and $493 million in the fourth quarter and full-year 2014, respectively, compared to $65 million and $377 million in the fourth quarter and full-year 2013. Net income per diluted common share was $0.03 and $0.08, respectively, in the fourth quarter and full-year 2014, versus $0.01 and $0.06 in the fourth quarter and full-year 2013. Adjusted EBITDA was $381 million and $1.47 billion, respectively, in the fourth quarter and full-year, up 17% and 26% versus the prior year periods.

“As our results demonstrate, SiriusXM had a great year by delivering to subscribers new and exciting music, sports, and talk programming; executing on our growth plan; and driving 36% growth in free cash flow per diluted share, all while investing in the future of the connected car,” said Jim Meyer, Chief Executive Officer, SiriusXM.

“We have once again set ambitious targets for 2015 to grow our subscriber base, revenue, adjusted EBITDA, and free cash flow to new, record-high levels. I’m confident in our ability to be creative and innovative as the leader in audio entertainment, making our superior service an even better experience for our subscribers in 2015,” added Meyer.

FOURTH QUARTER 2014 HIGHLIGHTS

FULL-YEAR 2014 HIGHLIGHTS

“Our repurchases of 739 million shares in 2014 represented approximately 12% of the shares outstanding at the beginning of last year. Even as we returned $2.5 billion to our stockholders, SiriusXM’s leverage remained steady at about 3.1 times EBITDA, a result of rapid growth in adjusted EBITDA and the conversion of our 7% Exchangeable Notes into equity in December. In the two years since we began our capital return program with a special dividend, we have paid our shareholders over $4.8 billion and retired more than 1.3 billion shares,” noted David Frear, Chief Financial Officer, SiriusXM.

2015 GUIDANCE

The company also reiterated its 2015 guidance, originally given on January 7, 2015, for net subscriber additions, revenue, adjusted EBITDA, and free cash flow:

Key Operating Metrics

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 exclude the impact of other income and expense, loss on extinguishment of debt, loss on change in value of derivatives 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 share-based payment expense is not directly related to the operational conditions of our business.

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 from the merger of Sirius and XM and share-based payment expense. We use this Non-GAAP financial measure to manage our business, to 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 twelve months ended December 31, 2014 and 2013:

(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 December 31, 2014 was $9,000.

(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 December 31, 2013 was $10,000.

(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 year ended December 31, 2014 was $39,000.

(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 year ended December 31, 2013 was $47,000.

Adjusted Cash Operating Expenses - We define this Non-GAAP financial measure as our actual operating expenses adjusted to exclude the impact of certain purchase price accounting adjustments from the merger of Sirius and XM, depreciation and amortization expense, and share-based payment expense. The following table reconciles our actual operating expenses to our adjusted cash operating expenses for the three and twelve months ended December 31, 2014 and 2013:

ARPU - is derived from total earned subscriber revenue, advertising revenue and other subscription-related revenue, excluding revenue associated with our connected vehicle business, 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. 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 connected vehicle customer service and billing expenses and 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 as share-based payment expense is not directly related 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 and free cash flow per diluted share - are derived from cash flow provided by operating activities, capital expenditures and restricted and other investment activity. The calculation for free cash flow and free cash flow per diluted share are as follows (in thousands, except share and per share data):

New vehicle consumer conversion rate - is defined as the percentage of owners and lessees of new vehicles that receive our satellite radio 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. 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 installation - or SAC, per installation, 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 satellite radio installations in new vehicles and shipments of aftermarket radios 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 installation, is calculated as follows (in thousands, except for installation amounts):
