Savox Communications Plc ("Savox" or the "Company") supplements the Finnish prospectus dated 8 June 2026 (the "Finnish Prospectus") with the information disclosed in the stock exchange release published on 14 June 2026, as well as with information relating to the timetable for the Offering (as defined below) and the Listing (as defined below). The Finnish Financial Supervisory Authority (the "FIN-FSA") has today on 15 June 2026 approved the Finnish supplement to the Finnish Prospectus (the "Finnish Supplement").

Savox has an initial public offering (the "Offering") underway, consisting of (i) a public offering to private individuals and entities in Finland (the "Public Offering") and (ii) an institutional offering to institutional investors in Finland and, in accordance with applicable laws, internationally outside of the United States (the "Institutional Offering"). In addition, the Company has filed a listing application with Nasdaq Helsinki Ltd ("Nasdaq Helsinki") to list Savox's shares first on the prelist and then on the regulated market maintained by Nasdaq Helsinki (the "Listing").

Cancellation in accordance with the Prospectus Regulation

If the Finnish Prospectus is supplemented in accordance with the Regulation (EU) 2017/1129 of the European Parliament and of the Council of 14 June 2017 as amended (the "Prospectus Regulation") due to a significant new factor, material mistake or material inaccuracy in the Finnish Prospectus that has become known after the FIN-FSA has approved the Finnish Prospectus, but before trading in the offer shares begins on the prelist Nasdaq Helsinki, investors who have already given their commitments before the supplement or correction of the Finnish Prospectus have, in accordance with the Prospectus Regulation, the right to cancel their commitments within three working days after the supplement has been published. The use of the cancellation right requires that the significant new factor, material mistake or material inaccuracy that led to the supplement or correction has become known before the closing of the offer period or the delivery of the offer shares to the investors, whichever occurs first. Any cancellation of a commitment must concern the total number of shares covered by the commitment given by an individual investor.

Procedure to cancel a commitment

An investor who has already given their commitment to subscribe for or purchase offer shares prior to the publication of the Finnish Supplement has the right to cancel their commitment within three (3) working days from the publication of the Finnish Supplement, i.e. at the latest by 18 June 2026 at 4:00 p.m. (Finnish time).

The cancellation of a commitment must be notified to the subscription place where the initial commitment was made, within the time limit set for such cancellation, as follows:

• A commitment made to Nordea may be cancelled by telephone in Nordea's phone services.
• Investors who have submitted their subscriptions via Nordnet must send a written cancellation request within the set time limit by e-mail to iaservices.fi@nordnet.fi or by delivering the cancellation to Nordnet’s office, subject to the following exceptions: a commitment submitted by Nordnet’s own customers via Nordnet’s online service can be cancelled via Nordnet’s online service by accepting a separate cancellation of a commitment by using Nordnet’s bank identifier.

A cancellation of a commitment applies to the entire commitment. After the time limit set for cancellation has expired, the cancellation right is no longer valid. If the commitment is cancelled, the subscription place refunds the sum paid for the offer shares to the bank account specified in the commitment. To Nordnet's own customers who gave their commitments via Nordnet’s place of subscription, the amount to be refunded will be paid to a Nordnet cash account. The payment is refunded as soon as possible after the cancellation, approximately within five (5) banking days of serving the subscription place with the cancellation notice. If an investor's bank account is in a different bank than the place of subscription, the refund will be paid to the investor's Finnish bank account in accordance with the payment schedule of the financial institutions, approximately no later than two (2) banking days thereafter. No interest will be paid on the refunded amount.

Timetable of the Offering and the Listing

Due to the cancellation right caused by the Finnish Supplement, the subscription periods of the Public Offering as well as the Institutional Offering have been amended as follows:

• The subscription period for the Public Offering will end on or about 17 June 2026 at 4:00 p.m. (Finnish time).
• The subscription period for the Institutional Offering will end on or about 18 June 2026 at 4:00 p.m. (Finnish time).

The Finnish Supplement will be available today on Savox's website at ipo.savox.com, on Nordea Bank Abp's ("Nordea") website at www.nordea.com/fi/savox and on Nordnet Bank AB's ("Nordnet") website at www.nordnet.fi/savox. An English language supplement to the Offering Circular prepared on the basis of the Finnish Supplement will be available today on Savox's website at ipo.savox.com, on Nordea's website at www.nordea.com/fi/savox and on Nordnet's website at www.nordnet.fi/savox.

INFORMATION TO DISTRIBUTORS

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the shares have been subject to a product approval process, which has determined that the shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the shares may decline and investors could lose all or part of their investment; the shares offer no guaranteed income and no capital protection; and an investment in the shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to any offering of the shares.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the shares and determining appropriate distribution channels.
