SiriusXM Reports Fourth Quarter and Full-Year 2015 Results

NEW YORK – February 2, 2016 – SiriusXM today announced fourth quarter and full-year 2015 operating and financial results, including record revenue of $1.2 billion and $4.6 billion, respectively, up 10% and 9% versus the prior year periods.

Net income totaled $135 million and $510 million in the fourth quarter and full-year 2015, respectively, compared to $143 million and $493 million in the fourth quarter and full-year 2014. Net income per diluted common share was $0.03 and $0.09 in the fourth quarter and full-year 2015, respectively, versus $0.03 and $0.08 in the fourth quarter and full-year 2014. Adjusted EBITDA was $396 million and $1.66 billion in the fourth quarter and full-year, respectively, up 4% and 13% compared to the prior year periods.

“We produced our best subscriber growth in eight years, taking our subscriber base to approximately 29.6 million. The company also set records in 2015 for revenue, adjusted EBITDA, and free cash flow. We are investing in new marketing capabilities, our connected vehicle business, new satellites, a next generation wideband chipset and, most importantly, our world-class and exclusive content. We expect that these investments, together with our long-standing focus on execution, will help us continue our long history of strong, profitable growth” said Jim Meyer, Chief Executive Officer, SiriusXM.

“SiriusXM’s strong, resilient business model and ability to deploy capital to benefit our stockholders present a compelling investment opportunity. Our content bundle of commercial-free music channels, live sports events, expanded comedy and entertainment programming remains a unique value in audio entertainment. And the development and deployment of our next-generation SXM17 entertainment platform and telematics services in connected vehicles position us well to continue our enviable place in the dashboard,” added Meyer.

FULL-YEAR 2015 HIGHLIGHTS

“During the fourth quarter, we spent $369 million to repurchase 92 million of our shares. In January, as our stock fell alongside the worldwide market declines, we accelerated our repurchases to nearly $200 million, repurchasing an additional 52 million shares. Our stock repurchase plan has now delivered $6.5 billion into the hands of our stockholders in just three years. We continue to maintain modest leverage of just 3.3 times adjusted EBITDA, and with no near term maturities and growing free cash flow, we have ample options on how we deploy our capital going forward,” remarked David Frear, Chief Financial Officer, SiriusXM.

Glossary

Adjusted EBITDA – EBITDA is defined as net income before interest expense, net of amounts capitalized; income tax expense and depreciation and amortization. We adjust EBITDA to exclude the impact of other income, loss on disposal of assets, 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 on-going core operating results period over period, (ii) base our internal budgets and (iii) compensate management. As such, 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, (iii) share-based payment expense and (iv) other significant operating expense (income) that do not relate to the on-going performance of our business. 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 believe the exclusion of share-based payment expense and loss on disposal of assets is useful as they are not directly related to the operational conditions of our business. We also believe the exclusion of settlements related only to the historical use of pre-1972 sound recordings is useful as it does not represent an expense incurred as part of normal operations for the period.

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:

Adjusted Net Income and Adjusted Earnings Per Share - We define these Non-GAAP financial measures as our actual net income adjusted to exclude the impact of certain purchase price accounting adjustments, the pre-1972 sound recordings legal settlements, the loss on disposal of assets, and the loss on change in value of derivatives, net of income tax expense. Adjusted earnings per share is derived from adjusted net income divided by our weighted average common shares outstanding. The following table reconciles our actual income before

income taxes to our adjusted net income for the three and twelve months ended December 31, 2015 and 2014:

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, 2015 and 2014:

(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, 2015 was $8,000.

(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, 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 twelve months ended December 31, 2015 was $35,000.

(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 twelve months ended December 31, 2014 was $39,000.

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, share-based payment expense, the pre-1972 sound recordings historical legal settlements, and the loss on disposal of assets. The following table reconciles our actual operating expenses to our adjusted cash operating expenses for the three and twelve months ended December 31, 2015 and 2014:

ARPU - is derived from total earned subscriber revenue, advertising revenue and other subscription-related revenue, excluding revenue associated with our connected vehicle business, 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:

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:

Free cash flow and free cash flow per diluted share - are derived from cash flow provided by operating activities, net of additions to property and equipment, restricted and other investment activity, and the return of capital from investment in unconsolidated entity, excluding the $210,000 pre-1972 sound recordings legal settlement payment. The calculation for free cash flow and free cash flow per diluted share are as follows:

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, divided by the number of satellite radio installations in new vehicles and shipments of aftermarket radios for the period. SAC, per installation, is calculated as follows:
