Antti Jääskeläinen, President and CEO of Posti, comments:

“Posti is the market leader in Finland in all three of our business areas: Postal Services, eCommerce and Delivery Services and Fulfillment and Logistics Services. Our direction for future value creation is clear. We will leverage our comprehensive distribution network, strong competitive position and well-known brand in building our future. Every Posti employee also has a key role as we develop Posti into an international, increasingly profitable delivery and fulfillment company. The listing is a significant step in Posti’s history.”

Sanna Suvanto-Harsaae, Chair of the Board of Directors of Posti, comments:

“I am very pleased that we can announce today the launch of Posti’s offering. Modern Posti is in good shape as a company and has a clear direction for the future. The listing will support Posti’s continued growth in line with its strategy. The key objective of the listing is to broaden the company’s ownership base – and I invite new investors to become owners of Posti.”

The background and reasons for the Listing

Posti is one of the leading delivery and fulfillment companies operating in Finland, Sweden and the Baltic countries. Posti offers services in three business areas: Postal Services, eCommerce and Delivery Services, and Fulfillment and Logistics Services. Postal Services’ offering includes delivery services, multichannel services and digital services, which cover, among other things, letters (both corporate and consumer letters), multichannel messaging solutions, newspaper and magazine delivery as well as addressed direct marketing services in Finland. eCommerce and Delivery Services’ offering covers parcel delivery services and groupage freight services in Finland and parcel delivery services in the Baltic countries. Fulfillment and Logistics Services covers contract logistics and in-house logistics in Finland and Sweden as well as a single warehouse in Norway.

The objectives of the Offering are to broaden the Company’s ownership base and enable the continued growth of Posti by improving its financial flexibility as a publicly listed company and strengthening recognition and awareness of Posti and its brand among investors, customers and other stakeholders.

Preliminarily a maximum of 1,000,000 Sale Shares are offered in the Public Share Sale for subscription by private individuals and entities in Finland. Private individuals subscribing for Sale Shares in the Bonus Share Sale will receive, for each ten Sale Shares allocated to them in the Bonus Share Sale, one Bonus Share at no additional cost, provided that the investor keeps the Sale Shares Entitling to Bonus Shares on their book-entry account continuously for a period of 12 months from the transfer of title, i.e., until on or about 10 October 2026. In order to participate in the Bonus Share Sale, the investor must also participate in the Listing Sale.

Preliminarily a maximum of 10,600,000 Sale Shares are offered in the Institutional Share Sale in private placements to institutional investors in Finland and internationally, including in the United States to persons reasonably believed by the Managers to be qualified institutional buyers as defined in Rule 144A under the U.S. Securities Act, pursuant to exemptions from the registration requirements of the U.S. Securities Act.

The Seller may decide, based on demand, to transfer Sale Shares without any restrictions between the Institutional Share Sale and the Public Share Sale in deviation from the preliminary number of Shares. The number of Sale Shares to be offered in the Public Share Sale is preliminarily approximately 8.6 percent of all Sale Shares. However, the minimum number of Sale Shares to be offered in the Public Share Sale shall be 1,000,000 Sale Shares (i.e., no less than 8.6 percent of all the Sale Shares) or, if the aggregate number of Sale Shares covered by the Commitments submitted in the Public Share Sale is smaller than this, such aggregate number of Sale Shares as covered by the Commitments.

In the Personnel Offering, preliminarily a maximum of 300,000 Personnel Shares and, in the event of oversubscription, a maximum of 200,000 additional Personnel Shares will be offered to the Personnel.

The Sale Price for the Sale Shares in the Share Sale is EUR 7.50 per Sale Share. The Sale Price may be changed during the subscription period, however, so that in the Public Share Sale the Sale Price will be no more than the original Sale Price of EUR 7.50 per Sale Share. The Subscription Price in the Personnel Offering is 10 percent lower than the Sale Price in the Public Share Sale. Thus, the Subscription Price per Personnel Share in the Personnel Offering is EUR 6.75.

The Seller is expected to grant the Managers (as defined below) an Over-allotment Option, exercisable by the Stabilization Manager on behalf of the Managers as stabilization manager within 30 days from commencement of trading in the Shares on the prelist of Nasdaq Helsinki (which is expected to be between 10 October 2025 and 9 November 2025), for up to 1,740,000 Additional Shares solely to cover over-allotments, if any. The Additional Shares correspond to approximately a maximum of 4.4 percent of the Shares and votes carried by them before the Personnel Offering and approximately a maximum of 4.3 percent after the Personnel Offering, assuming that all the Personnel Shares offered are subscribed for in full.

The Seller aims to raise gross proceeds of approximately EUR 100 million from the Share Sale (assuming that all Sale Shares are sold and that the Over-Allotment Option is used in full). The Company expects to receive gross proceeds of approximately EUR 2 million from the Personnel Offering.

The Company expects to enter into a placing agreement, together with the Seller, with the Managers on or about 9 October 2025 (the “Placing Agreement”). Pursuant to the Placing Agreement, the Seller agrees to sell the Sale Shares and the possible Additional Shares and the Company agrees to issue the Personnel Shares to subscribers procured by the Managers.

In connection with the Offering, the Company and the Seller are expected to commit to a lock-up arrangement of 360 days for the Company and 180 days for the Seller, calculated from the first day of trading in the Shares. As a precondition for participation in the Personnel Offering, persons eligible to participate in the Personnel Offering must undertake the lock-up upon submitting their subscriptions, which ends, for part of members of the Board of Directors and the Leadership Team of the Company, 360 days following the first day of trading in the Shares, and, for part of other personnel of the Company, 180 days following the first day of trading in the Shares. The participants of the Personnel Offering accept upon submitting their subscriptions that the above-mentioned lock-up will be binding upon them without any further action and that it will be recorded to their securities accounts on the order by the Company. The Sale Shares Entitling to Bonus Share will be subject to a transfer restriction for a period of 12 months from the transfer of title of such Sale Shares, i.e., until on or about 10 October 2026.

Before the execution of the Offering, the Shares of the Company have not been subject to trading on any regulated market or multilateral trading facility. The Company intends to submit a listing application to Nasdaq Helsinki to list the Shares on the Official List of Nasdaq Helsinki. Trading in the Shares is expected to commence on the prelist of Nasdaq Helsinki on or about 10 October 2025 and on the Official List of Nasdaq Helsinki on or about 14 October 2025.

The Finnish Financial Supervisory Authority is expected to approve the Finnish Prospectus on or about 29 September 2025. The Finnish Prospectus will be available on or about 29 September 2025 on the Company’s website at www.posti.com/listautuminen.

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 the Offering.
