Bergen, 25 April 2023: The board of directors of BerGenBio ASA (the "Company")
has today, subject to approval by the Annual General Meeting (the "AGM") on 22
May 2023, resolved to carry out a rights issue of shares (the "New Shares") with
preferential subscription rights for existing shareholders (the "Rights Issue")
to raise gross proceeds of up to NOK 250 million. Subscribers in the Rights
Issue will for every two New Shares allocated and subscribed receive one warrant
to subscribe for one new share in the Company (the "Warrants"). Subsequent
exercise of Warrants will increase the gross proceeds to the Company.

Certain existing shareholders and external investors (jointly the
"Underwriters") have underwritten NOK 175 million of the Rights Issue and
certain existing shareholders have pre-committed to subscribe, including Meteva
AS and Investinor AS which have pre-committed to subscribe for NOK 65 million
and NOK 17.5 million respectively, which is included in the underwriting amount
of NOK 175 million. In addition, management and board members in the Company
will subscribe for New Shares in the Rights Issue with an aggregate subscription
price of at least NOK 0.5 million.

The net proceeds from the Rights Issue and exercised Warrants will be used to
further advance the Company's strategy for non-small cell lung cancer ("NSCLC"),
severe respiratory infections and general corporate purposes. After assessing
the significant drop in hospitalizations attributed to COVID-19 during the 2022
-23 winter season, the EU-SolidAct Trial Steering Committee in accordance with
the Company has decided to pause the trial until a potential acceleration in
COVID-19 hospitalizations warrant further evaluation ofbemcentinibin this
population.

Notice of the AGM, including proposed resolutions regarding the Rights Issue, is
expected to be sent to the shareholders on 28 April 2023.

Arctic Securities AS and Carnegie AS have been engaged as managers for the
Rights Issue (the "Managers"). H.C. Wainwright & Co. acted as financial advisor
to the Company. Advokatfirmaet Thommessen AS is acting as legal advisor to the
Company in connection with the Rights Issue.

Underwriting

Pursuant to, and subject to, the terms and conditions of the underwriting
agreements between the Company and the Underwriters (the "Underwriting
Agreements"), the Underwriters have undertaken on a pro-rata basis (not jointly)
to underwrite an aggregate subscription amount in the Rights Issue of NOK 175
million (the "Total Underwriting Obligation"), subject to potential reduction
for Meteva AS described below. Any New Shares subscribed in the Rights Issue
will reduce the underwriting commitment of the Underwriters but not pre
-commitments from existing shareholders.

Each Underwriter is entitled to an underwriting fee of 12% of its respective
underwriting obligation, to be settled in cash or new shares in the Company
issued at the subscription price in the Rights Issue, or through a combination
of cash and new shares, at the Underwriter's election. The selection of
shareholders who have been invited to underwrite has been based on objective
criteria.

The Underwriters have undertaken to vote any shares held by them at the time of
the AGM in favour of the Rights Issue.

Meteva AS' underwriting and pre-commitment to subscribe for New Shares are
limited such that Meteva AS' holding of shares in the Company shall not exceed
1/3, and any remaining underwriting and pre-commitment shall be satisfied in the
form of a convertible loan from Meteva AS. Such convertible loan shall be
convertible into new shares in the Company at a conversion price equal to the
subscription price in the Rights Issue and otherwise on terms similar to those
in the existing loan agreement between the Company and Meteva AS announced
through the Company's stock exchange announcement dated 25 October 2022 (the
"Meteva Loan").

Subscription price, subscription rights, Warrants and proceeds

The subscription price for the New Shares to be issued in the Rights Issue, and
thus the exact number of New Shares and the exact amount of the share capital
increase, will be proposed by the board of directors, based on a recommendation
from the Managers, the day prior to the AGM. Pursuant to the Underwriting
Agreements, the subscription price in the Rights Issue shall be the theoretical
ex rights price (TERP) based on the volume-weighted average price (VWAP) of the
Company's shares on the Oslo Stock Exchange the three trading days prior to the
AGM, less a discount of at least 37.5%. The board of directors' resolution in
this respect will be announced through a stock exchange announcement on the day
prior to the AGM and be reflected in the final proposed resolution to the AGM.

Pursuant to section 10-4 of the Norwegian Public Limited Companies Act, the
shareholders of the Company at the date of the AGM, and who are not resident in
a jurisdiction where such offering would be unlawful or, (in jurisdictions other
than Norway) require any prospectus, filing, registration or similar action,
will be granted a preferential right to subscribe for and be allocated the New
Shares in proportion to the number of shares in the Company they own as of that
date, and will according to the board of directors' proposal receive
subscription rights proportionate to their existing shareholding as registered
in the Company's shareholder register in the Norwegian Central Securities
Depository (the VPS) at the expiry of 24 May 2023. Provided that a purchase of
shares is made with ordinary T+2 settlement, shares purchased up to and
including 22 May 2023 will give the right to receive subscription rights,
whereas shares purchased from and including 23 May 2023, will not give the right
to receive subscription rights. The subscription rights will be tradable and
listed on the Oslo Stock Exchange from and including the first day of the
subscription period and until 16:30 (Oslo time) two trading days prior to the
expiry of the subscription period. Over-subscription and subscription without
subscription rights will be permitted.

The subscribers in the Rights Issue will without cost be allocated one Warrant
issued by the Company for every two New Shares allocated to, and paid by, them
in the Rights Issue. Each Warrant will give the holder a right to subscribe for
one new share in the Company at a subscription price equal to the volume
-weighted average price (VWAP) of the Company's shares on the Oslo Stock
Exchange on the three last trading days prior to the first date on which the
holder can exercise the warrant in each exercise period less 30%, but in any
event not exceeding the subscription price in the Rights Issue plus 30%. The
Warrants may be exercised during two exercise periods: (i) within the first 14
days after the Company's announcement of its Q3 2023 quarterly financial report
and (ii) from 1 April 2024 to 14 April 2024. Other terms and conditions for the
Warrants will be determined by the AGM. The Company shall use reasonable efforts
to seek to ensure that the Warrants are admitted to trading on a relevant
trading venue as soon as possible following completion of the Rights Issue but
there can be no assurance that such admittance to trading will be obtained.

The maximum gross proceeds from the Rights Issue will be NOK 250 million and the
minimum gross proceeds will be NOK 175 million (provided that a portion of such
gross proceeds may be in the form of a convertible loan from Meteva AS as
described above). If the Company draws on the existing Meteva Loan prior to the
start of the subscription period in the Rights Issue, Meteva AS has the right to
convert up to the aggregate drawdown amount to shares in the Rights Issue at the
subscription price in the Rights issue, and the gross cash proceeds from the
Rights Issue will in such event be correspondingly reduced.

The gross proceeds from the exercise of Warrants will depend on the number of
Warrants issued and exercised, as well as the final exercise price for the
Warrants, determined as described above.

Prospectus and indicative timeline

In connection with the Right Issue a prospectus (the "Prospectus") will be
prepared which is subject to the approval by the Norwegian Financial Supervisory
Authority (the "NFSA"), expected to be obtained on 26 May 2023. The prospectus
will be published prior to the commencement of the subscription period and will
form the basis for subscriptions in the Right Issue. Provided that the
prospectus is approved by the NFSA in time, the subscription period for the
Rights Issue will commence on 30 May 2023 and expire on 13 June 2023 at 16:30
hours (Oslo time). In the event that the prospectus is not approved in time to
uphold this subscription period, the subscription period will commence on the
second trading day on the Oslo Stock Exchange following the approval and expire
at 16:30 hours (Oslo time) two weeks thereafter. A further description of the
Rights Issue and of other circumstances that must be considered upon
subscription of shares in the Rights Issue will be included in the Prospectus.
