Altice NV's shareholders approve the separation of Altice USA from Altice NV

May 18, 2018 - At today's annual general meeting of Altice N.V. ("Altice NV" or the "Company",

Euronext: ATC, ATCB) (the "AGM"), shareholders of Altice NV approved the intended separation of Altice USA, Inc. ("Altice USA", NYSE: ATUS) from Altice NV (which will be renamed "Altice Europe") (the "Separation").

The Separation is to be effected by a special distribution in kind by Altice NV of its 67.2% interest in Altice USA to Altice NV shareholders out of Altice NV's share premium reserve (the "Distribution").1 The Separation was announced by Altice NV on January 8, 2018.

In connection with the Separation, Altice NV today announces the following dates:

Altice NV shares will be traded ex-dividend as of May 22, 2018 on Euronext Amsterdam. The Distribution record date will be May 23, 2018. Each shareholder of the Company as of the

Distribution record date will be entitled to receive 0.4163 share of Altice USA common stock for every share held by such shareholder in the Company's capital. Between May 24, 2018 and June 4, 2018 ("the "Election Period"), each shareholder will be given the opportunity to elect the percentage of shares of Altice USA Class A common stock and shares of Altice USA Class B common stock such shareholder will receive in the Distribution, whereby the number of shares of Altice USA Class B common stock to be distributed will be subject to a cap of 50% of the total shares of Altice USA common stock being distributed (the "Class B Cap"); if the Class B Cap is exceeded, the shares of Altice USA Class B common stock delivered to the

Company's shareholders of record who elect to receive shares of Altice USA Class B common stock will be subject to proration, and such shareholders will receive shares of Altice USA

Class A common stock in lieu of the portion of shares of Altice USA Class B common stock that is cut back. If a shareholder of the Company does not make an election, the Distribution will be paid to such shareholder in the form of Altice USA Class A common stock. Based on the final results of the election and any proration, Altice NV will convert shares of Class B common stock into the requisite number of shares of Class A common stock for the Distribution, which we expect will take place on June 8, 2018.

The distribution will exclude shares indirectly owned by Altice NV through Neptune Holding US LP.

Prior to the start of the Election Period, Altice USA will publish a prospectus in connection with the planned Distribution on Altice N.V.'s website(www.altice.net/separation-altice-usa-altice-

nv). Shareholders of Altice NV should carefully read this entire prospectus before electing the percentage of shares of Altice USA Class A common stock and shares of Altice USA Class B common stock they wish to receive in the Distribution.

Attached to this press release is a memo on Altice NV's anticipated share price adjustment as a result of the Distribution.

Memo on Altice NV's anticipated share price adjustment

On January 8, 2018, Altice NV announced a Group reorganization and proposed the separation of Altice USA from Altice NV, to be effected by a spin-off of Altice NV's 67.2% interest in Altice USA2 through a distribution in kind out of Altice NV's share premium reserve to Altice NV shareholders (the "Separation"). On the same day, Altice USA announced that its Board of Directors approved in principle a $1.5bn special cash dividend to all Altice USA shareholders payable to shareholders prior to completion of the Separation. Thereafter, on May 15, 2018, the Board of Directors of Altice USA declared a one-time cash dividend of $2.035 per share of Altice USA Class A common stock and Class B common stock. The dividend is payable to Altice USA shareholders of record at the close of business on May 22, 2018. The payment date for the one-time cash dividend Altice USA declared will be two business days prior to the Separation date.

Following the vote in favour of the Separation by Altice NV shareholders at the Annual General Meeting held on May 18, 2018 and provided regulatory approval of a prospectus in connection with the distribution is obtained from the AFM, the Separation is currently expected to become effective on June 8, 2018. However, the date of the distribution is dependent on the timing of the AFM's approval.

A technical adjustment in the share price of Altice NV is expected, as follows.

Altice NV share price adjustment: On Separation, Altice NV shareholders of record at the close of business on May 23, 2018 will receive Altice USA shares at a ratio of 0.4163 per Altice NV share held. The expected share price adjustment will depend on the share prices and exchange rate prevailing on the dates in question, however the following example illustrates the pro forma impact assuming these closing prices and rate on May 21, 2018:

• - Altice NV price: 8 euros per share

• - Altice USA price: $20 per share

• - Altice USA special dividend: $2.035 per share

• - 1 euro = $1.1900 USD

Altice NV expected price adjustment = 0.4163 x (20 - 2.035) x 1/1.1900 = 6.2847 euros reduction, so the expected Altice NV share price following Separation would be 1.7153 euros.

The adjustment illustrated above is expected to occur in the opening price of Altice NV shares on May 22, 2018 and does not reflect any other factors that may affect the opening price of Altice NV shares on the ex-dividend date.

The distribution will exclude shares indirectly owned by Altice NV through Neptune Holding US LP.
