(the "CB Commitment").

Further, Atlas has undertaken to finance the Company's remaining financial needs
until end of June 2025, up to a monthly cash requirement of NOK 4 million (the
"Financing Commitment"), complementing the proceeds from the Rights Issue
including proceeds from investors' exercise of the Warrants in December 2024. In
addition, as a related transaction to the Rights Issue, Atlas shall settle NOK
15 million of the amount owed to Atlas under the Investment Agreement and Bond
Terms by the issuance of new shares at the subscription price in the Rights
Issue (the "Conversion").

The final allocation of the new shares will take place tomorrow, on 9 July 2024,
in accordance with the allocation criteria set out in the Company's securities

About Circio

Building next generation RNA therapeutics

Circio Holding ASA is a biotechnology company developing novel circular RNA gene
therapies and immunotherapy medicines.

Circio has established a unique circular RNA (circRNA) platform for genetic
medicine. The proprietary circVec technology is based on a modular genetic
cassette design for efficient biogenesis of multifunctional circRNA from DNA and
viral vectors, which can be deployed in multiple disease settings. The circVec
platform has demonstrated enhanced and more durable protein expression than
classic mRNA vector systems, and has the potential to become the new gold
-standard for DNA and virus-based therapeutics in the future. The circRNA R&D
activities are being conducted by the wholly owned subsidiary Circio AB based at
the Karolinska Institute in Stockholm, Sweden.

In addition, Circio is developing a cancer vaccine, TG01, targeting KRAS driver
mutations. TG01 is currently being tested in three clinical trials: RAS-mutated
pancreatic cancer and lung and non-resectable pancreatic cancer in US, and
multiple myeloma in Norway. These studies are being run through academic
collaborative networks, supported by prestigious research grants from Innovation
Norway and the Norwegian Research Council, creating read-outs and future
optionality for the program at low cost to Circio.
