Announcement of Magyar Telekom Plc. regarding the dividend payment and the actual amount of gross dividend per share for business year 2021

Budapest - April 25, 2022 - Magyar Telekom (Reuters: MTEL.BU and Bloomberg: MTELEKOM HB, hereinafter the "Company"), the leading Hungarian telecommunications service provider announces that, in accordance with the resolution of the Company's Annual General Meeting held on April 12, 2022, the Company will pay its shareholders a total dividend of HUF 15,000,000,000 from the profit of 2021. The Company distributes the dividends for its own shares, currently 45,777,539 pcs., among the shareholders who are entitled for dividends, hence the actual amount of gross dividend per ordinary Magyar Telekom share (ISIN number: HU0000073507) for the business year 2021 shall be HUF 15.05. Dividend payment will start on May 10, 2022.

The record date related to the dividend payment is April 29, 2022. Shareholders shall be entitled to dividend who own Magyar Telekom shares at the record date and requested to be registered in the Share Register of the Company. The last day when shares can be bought on the Budapest Stock Exchange that will be entitled to the dividend paid for the 2021 business year is April 27, 2022. In line with the lapse period specified in the Civil Code the dividend for the business year 2021 can be collected for a further 5 years, starting from the first day of the dividend payment (i.e. not later than May 10, 2027).

The dividend will be transferred to shareholders' accounts - attached to securities accounts at the account-keepers, or to another bank account specified by the shareholder - from May 10, 2022. The dividend can only be transferred if the account keeper sends all information in the specified form to the KELER Központi Értéktár Zártkörűen Működő Részvénytársaság (hereinafter: "KELER Ltd."), acting as agent for the dividend payment of the Company. Neither the Company nor KELER Ltd. is responsible for any payment delay resulting from insufficient or incomplete information provided by account keepers or resulting from the time required for data processing. We would like to take this opportunity to remind our shareholders to contact their account keeper and check that they have all the information necessary for the dividend payment and draw their attention to submit their data in the course of the recording process. If the account keeper does not submit the data relating to the shareholder, required for dividend payment, in the course of the recording process to KELER Ltd., but at a later date, then the Company will transfer the dividend through KELER Ltd. once in a month, by the 5th working day following the month of the reporting.

In case of individuals

In case of individuals, the Company will, through its agent (KELER Ltd.), transfer the dividend after deduction of the personal income tax to the account-keeper's bank account, or to another bank account specified by the shareholder to its account keeper. In case of domestic private individuals, the following data is required for dividend payment: name (surname, forename), date of birth and tax ID of the shareholder, place of residence (address). In case of foreign private individuals, the following data is required for dividend payment: name (surname, forename), place and date of birth, passport number or tax ID issued by the Hungarian tax authority (in case both passport number and tax ID is missing, driving licence number or other document suitable for the identification of the private individual), permanent address of the shareholder and address (place of residence) in Hungary, if the shareholder has any. Dividends paid for business year 2021 are subject to a personal income tax of 15% [based on Section 8 (1) and Section 66 (1) a) of Act CXVII of 1995 on Personal Income Tax (hereinafter: the "Personal Income Tax Act")] except for equities entitled for dividend payment (in present case shares) held on long term investment account and recorded in the register of time deposits. In this case, based on the information provided by the credit institutions or investment firms where the account is held, dividends will be transferred to the individual shareholders without the deduction of personal income tax. Pursuant toSection 67/B (6) c) of the Personal Income Tax Act, credit institutions and investment firms notify the issuer, that in connection with this income, it shall not deduct the tax.

In case of foreign domiciled individual shareholders if an inter-state treaty exists then the tax rate (lower than 15%) according to the inter-state treaty will be deducted by the payer for shareholders who submit all documents specified in Annex 7 of the Personal Income Tax Act to the Issuer Department of KELER Ltd. (1074 Budapest, Rákóczi út 70-72.) not later than April 29, 2022. We remind account-keepers that we can only accept certificates of residency issued by foreign tax authorities regarding the tax year 2022; a copy of the document issued in English by the foreign tax authority or its Hungarian translation prepared by a specialist translator or a copy of any of these will be acceptable as certificate. If a foreign domiciled individual is not able to certify his or her residency, the payer can accept the written declaration on the residency. The payer shall keep the declaration and the certificate of residency. If a certificate of beneficial ownership is also required by the treaty on avoidance of double taxation, this certificate shall be translated into Hungarian by a specialist translator to be acceptable. The certificate of beneficial ownership can also be issued in Hungarian. If neither certificate of residency, nor a notice (declaration) that documents will be presented later, arrives at KELER Ltd. by April 29, 2022, the dividend will be transferred after deduction of 15% personal income tax. If a foreign domiciled individual shareholder has the documents specified in Annex 7 to the Personal Income Tax Act and there is an inter-state treaty on avoidance of double taxation based on which a preferential tax rate can be used, but the shareholder fails to submit the documents to KELER Ltd. by April 29, 2022 and therefore receives dividend after deduction of 15% income tax, the shareholder may apply, in accordance with Section 4 of Annex 7 to the Personal Income Tax Act, to the national tax and customs administration authority of Hungary, submitting certificate of residency and tax certificate issued by the payer, and claim the difference between the preferential tax rate and 15%. The tax authority shall remit the amount of such tax difference to the payment account specified by the foreign domiciled individual shareholder.

• In the lack of an inter-state treaty the dividends will be paid after deducting a personal income tax of 15%.

• In case of shares held on long term investment account ("Tartós Befektetési Számla")

• In case of shares held by domestic and foreign individuals on long term investment account, no tax (personal income tax) will be deducted from the dividends (pursuant to Section 67/B (6) c) and Annex 7 of the Personal Income Tax Act). Account-keepers are required to indicate to KELER Ltd., acting as agent in the dividend payment of the Company, that the shares held on a long term investment account (in the register of time deposits), simultaneously with claiming the dividend, otherwise the dividends will be paid after deducting a personal income tax of 15%.

In case of legal entities

In case of legal entities, the Company will, through its agent (KELER Ltd.), based on the specified data (in the case of Hungarian domiciled legal entities: company name, registered office (premises), tax ID number; in the case of foreign domiciled legal entities: company name and registered office, transfer the dividends to the bank account specified by the shareholder's account keeper. In case of legal entities, no tax will be deducted from the dividends.

In case of nominees

The dividends will be paid to nominees, as defined in the Act CXX of 2001 on the Capital Markets, based on the shareholder identification ordered for this purpose.

As a general rule, the dividends will be paid to nominees after deducting personal income tax of 15%.

If the account keeper of the nominee specifies in the course of the recording process the number of shares held by individual shareholders and the number of shares held by legal entities (not individual shareholders) from the total number of shares represented by the nominee, then the dividends will be paid after applying the relevant tax rate. In the case of dividends for shares held by legal entities, no tax will be deducted from the dividends. In the case of shares held by individual shareholders, personal income tax of 15% will be deducted from the dividends. If the shares represented by the nominee relate to foreign domiciled individual shareholders who intend to receive their dividends through the application of a preferred tax rate, then those shareholders should be recorded separately in the course of the recording process and they should act according to the above paragraph starting with "If a foreign domiciledindividual shareholder". If the shares represented by the nominee relate to domestic individual shareholders, suppling data required in case of individual shareholders (name (surname, forename), date of birth, tax ID, address of the shareholder) is compulsory. If data required in case of domestic individual shareholders is missing than dividend will not be paid.

We draw the attention of nominees that the Company will apply the tax rate and perform its data supply obligation based on the information received in the course of the identification procedure and according to the appropriate regulations. As the taxation of dividends paid to legal entities and those paid to private individuals are different, nominees will be liable for damages (e.g. consequences under tax law) caused by incorrect information provided by the nominees.

Tax certificates

The Company will issue and will send to its individual shareholders no later than January 31, 2023, a certificate stating the name of payer, the name (corporate name), tax identification number, registered office (sites) or home address of the income's recipient, the legal title of payment, the year when the dividend was paid, the date of issue of the certificate, the tax base and the amount of tax assessed.

In cases where dividends are paid to nominees and the nominee declares, pursuant to Section 8 of Annex 7 to the Personal Income Tax Act, in a duly signed document issued at the latest by the last day of the calendar year when the payment is made, in Hungarian or Hungarian and English language, the name (corporate name), permanent residence, registered offices, date and place of birth and nationality of the foreign persons to whom the dividend is (to be) paid and the amount of dividend (to be) paid to them in HUF, then the Company will issue the tax certificate and will perform its data supply obligation based on this nominee declaration.

If the above mentioned detailed declaration is not available, the Company will issue the tax certificate stating the name (corporate name) and registered office of the nominee and in the case of Hungarian domiciled entities, the tax identification number and the amount of dividends paid will be provided.

Dividend payment for previous years

The Company pays a HUF 25 gross dividend for the business year 2016, HUF 25.13 gross dividend for the business year 2017, HUF 25.21 gross dividend for the business year 2018, HUF 20.17 gross dividend for the business year 2019 and HUF 15 for business year 2020 per ordinary share.

The company started payment of the 2016 dividend on May 23, 2017. In line with the lapse period specified in the Civil Code, the dividend for business year 2016 can be collected for a further 5 years, starting from the first day of the dividend payment, i.e. not later than May 23, 2022.

We would like to remind shareholders who have still not received their dividends for previous business years to contact their securities account manager and request payment of the dividend within the lapse period specified.

Dividends paid for previous years for private individuals are subject to 15% personal income tax.

In case of legal entities, no tax will be deducted from the dividends for prior years.
