Castellum Aktiebolag ("Castellum") has today, 13 February 2025, acquired 100
shares in Entra ASA ("Entra") at a price of NOK 110.40 per share. Following the
acquisition, Castellum holds 60,710,724 shares in Entra, representing
approximately 33.333355% of the outstanding shares and votes in the company. 

As a result of the acquisition, Castellum will hold shares representing more
than 1/3 of the votes in Entra, triggering an obligation to make a mandatory
offer for the remaining shares in Entra pursuant to chapter 6 of the Norwegian
Securities Trading Act.

Castellum intends to make a mandatory offer to acquire the remaining shares in
Entra within the four-week period set out in the Norwegian Securities Trading
Act, subject to approval of an offer document and the offer by Oslo Børs ASA in
its capacity as takeover supervisory authority in Norway (the "Offer"). The
Offer will be made at NOK 110.40 per share in Entra.

Entra's largest shareholder, Fastighets AB Balder, controlling approximately
39.98% of the shares and votes in Entra, has informed Castellum that it will not
accept the Offer.

Joacim Sjöberg, Chief Executive Officer of Castellum, says: 

"Entra is a very fine company with a high-quality property portfolio mainly in
central Oslo. A strong customer base with long leases and a large and attractive
project portfolio makes the company well positioned for the future. We have now
acquired additional shares and as a consequence we will make a mandatory offer
and are happy to further increase our shareholding."

Advisor
Nordea Bank Abp, filial i Sverige, is acting as financial advisor to Castellum.

Notice to U.S. Holders 

Holders of shares of Entra in the United States ("U.S. Holders") are advised
that Entra's shares are not listed on a U.S. securities exchange and that Entra
is not subject to the periodic reporting requirements of the U.S. Securities
Exchange Act of 1934, as amended (the "U.S. Exchange Act"), and is not required
to, and does not, file any reports with the U.S. Securities and Exchange
Commission (the "SEC") thereunder. 

The Offer will be made for the issued and outstanding shares of Entra, a company
incorporated under Norwegian law, and is subject to Norwegian disclosure and
procedural requirements, which may be different from those of the United States.
The Offer will be made in the United States pursuant to Section 14(e) of the
U.S. Exchange Act and Regulation 14E thereunder, to the extent applicable and
subject to any available exemptions, and otherwise in compliance with the
disclosure and procedural requirements of Norwegian law, including with respect
to the Offer timetable, settlement procedures and timing of payments, which may
be different from requirements or customary practices in relation to U.S.
domestic tender offers. The Offer will be made to U.S. Holders on the same terms
and conditions as those made to all other holders of shares of Entra to whom an
offer is made. Any information document, including the Offer Document, will be
disseminated to U.S. Holders on a basis comparable to the method that such
documents are provided to Entra's other shareholders to whom an offer is made.
The Offer will be made by Castellum and no one else. U.S. Holders are encouraged
to consult with their own advisors regarding the Offer.

To the extent permissible under applicable law or regulations, Castellum and its
affiliates or brokers (acting as agents for Castellum or its affiliates, as
applicable) may from time to time and during the pendency of the Offer, and
other than pursuant to the Offer, directly or indirectly, purchase or arrange to
purchase, shares in Entra, or any securities that are convertible into,
exchangeable for or exercisable for such shares, outside the United States, so
long as those acquisitions or arrangements comply with applicable Norwegian law
and practice and the provisions of such exemption. These purchases may occur
either in the open market at prevailing prices or in private transactions at
negotiated prices. To the extent information about such purchases or
arrangements to purchase is made public in Norway, such information will be
disclosed by means of an English language press release via an electronically
operated information distribution system in the United States or other means
reasonably calculated to inform U.S. Holders of such information. If the
consideration paid by Castellum or its affiliates in any transaction after the
public announcement of the Offer, but prior to the expiry of the acceptance
period for the Offer, is greater than the Offer price, the Offer price shall be
increased to match that price. In addition, the financial advisors to Castellum
may also engage in ordinary course trading activities in securities of Entra,
which may include purchases or arrangements to purchase such securities as long
as such purchases or arrangements are in compliance with applicable law. To the
extent required in Norway, any information about such purchases will be made
public in Norway in the manner required by Norwegian law.

Neither the SEC nor any U.S. state securities commission has approved or
disapproved the Offer, passed upon the merits or fairness of the Offer, or
passed any comment upon the adequacy, accuracy or completeness of the disclosure
in this announcement. Any representation to the contrary is a criminal offense
in the United States.

It may be difficult for Entra's shareholders to enforce their rights and any
claims they may have arising under the U.S. federal securities laws in
connection with the Offer, since Castellum and Entra are located in non-U.S.
jurisdictions, and some or all of their respective officers and directors may be
residents of non-U.S. jurisdictions. Entra's shareholders may not be able to sue
Castellum or Entra or their respective officers or directors in a non-U.S. court
for violations of the U.S. federal securities laws. It may be difficult to
compel Castellum and Entra and their respective affiliates to subject themselves
to a U.S. court's judgment.
