CVC EarningsRelease 3-31-15 Exhibit 99.1

FOR IMMEDIATE RELEASE

CABLEVISION SYSTEMS CORPORATION REPORTS FIRST QUARTER 2015 RESULTS Bethpage, NY, May 4, 2015 - Cablevision Systems Corporation (NYSE:CVC) today reported financial results for the first quarter ended March 31, 2015.

First quarter consolidated net revenues increased 2.5% to $1.615 billion, consolidated adjusted operating cash flow ("AOCF")1 increased 4.5% to $454.0 million and consolidated operating income increased 8.0% to $223.8 million, all compared with the prior year period.
Operating highlights for the first quarter include:
• Average Monthly Cable Revenue per Customer ("RPC") of $155.34, an increase of
$7.12 or 4.8%, compared with the prior year period.
• Consolidated Free Cash Flow from Continuing Operations1 of $49.0 million.
Cablevision CEO James L. Dolan said, "Cablevision had a solid start to 2015 with growth in net revenue, AOCF and revenue per customer. As we move through the year, we will continue to address evolving consumer demand by expanding our product offerings to provide greater value and flexibility. Connectivity is the wave of the future, and we plan to leverage our industry-leading position to be the preferred choice for consumers in our market."

Cable

Cable includes our Optimum-branded digital cable television, high-speed Internet and voice services as well as Optimum WiFi, the nation's most robust WiFi network.
Cable net revenues for the first quarter 2015 increased 2.4% to $1.452 billion, AOCF increased 0.8% to $446.6 million and operating income increased 1.0% to $252.1 million, all compared with the prior year period. First quarter net revenue growth primarily reflects rate initiatives and continued disciplined pricing strategies, partially offset by a decline in customers. First quarter AOCF reflects the increase in revenue and lower employee and customer service-related costs, partially offset by higher programming and marketing costs, as compared to the prior year period.
The following table illustrates the change in the Cable customer base during the first quarter of
2015:

12.8% to $43.4 million and operating income increased 10.4% to $19.3 million, each as compared with the prior year period. First quarter results primarily reflect an increase in revenue from Ethernet services.

First quarter net revenues increased 0.4% to $81.8 million, AOCF deficit decreased 23.9% to
$35.9 million and operating loss decreased 20.6% to $47.6 million, all compared with the prior year period. First quarter net revenue growth primarily reflects increased advertising revenue at News
12 Networks partially offset by lower advertising revenue at Newsday. First quarter AOCF reflects a decrease in expenses at Newsday due to lower operating costs and a distribution agreement settlement, as well as reduced expenses at corporate and certain other businesses.

Other Matters

On May 1, 2015, the Board of Directors of Cablevision declared a quarterly dividend of $0.15 per share on each outstanding share of Cablevision NY Group Class A Common Stock and Cablevision NY Group Class B Common Stock. This quarterly dividend is payable on June 12, 2015 to shareholders of record at the close of business on May 22, 2015.
There were no stock repurchases during the first quarter of 2015. As of March 31, 2015, Cablevision had approximately $455 million available under its stock repurchase authorization.

Non-GAAP Financial Measures

We define adjusted operating cash flow ("AOCF"), which is a non-GAAP financial measure, as operating income (loss) before depreciation and amortization (including impairments), excluding share-based compensation expense and restructuring charges or credits. Because it is based upon operating income (loss), AOCF also excludes interest expense (including cash interest expense) and other non-operating income and expense items. We believe that the exclusion of share-based compensation expense allows investors to better track the performance of the various operating units of our business without regard to expense associated with awards of restricted shares, restricted stock units and stock options that are not expected to be made in cash.
We present AOCF as a measure of our ability to service our debt and make continuing investments, including in our capital infrastructure. We believe AOCF is an appropriate measure for evaluating the operating performance of our business segments and the company on a consolidated basis. AOCF and similar measures with similar titles are common performance measures used by investors, analysts and peers to compare performance in our industry. Internally, we use net revenues and AOCF measures as the most important indicators of our business performance, and evaluate management's effectiveness with specific reference to these indicators. AOCF should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), cash flows from operating activities, and other measures of performance and/or liquidity presented in accordance with U.S. generally accepted accounting principles ("GAAP"). Since AOCF is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies. For a reconciliation of AOCF to operating income (loss), please see page 6 of this release.
We define Consolidated Free Cash Flow from Continuing Operations ("Free Cash Flow"), which is a non-GAAP financial measure, as net cash from operating activities (continuing operations) plus any excess tax benefit related to share-based awards less capital expenditures (continuing operations), all of which are reported in our Consolidated Statement of Cash Flows. Net cash from operating activities excludes net cash from operating activities of our discontinued operations. We believe the most comparable GAAP financial measure of our liquidity is net cash from operating activities. We believe that Free Cash Flow is useful as an indicator of our overall liquidity, as the amount of Free Cash Flow generated in any period is representative of cash that is available for debt repayment and other discretionary and non-discretionary cash uses. It is also one of several indicators of our ability to make investments and/or return capital to our shareholders. We also believe that Free Cash Flow is one of several benchmarks used by analysts and investors who follow our industry for comparison of our liquidity with other companies in our industry, although our measure of Free Cash Flow may not be directly comparable to similar measures reported by other companies.
