Herning, Denmark, 28 June 2023 - With reference to the announcement made 19 June
2023, Everfuel today provides a status update on the hydrogen trailer fleet.

The detailed investigation of the leak has identified the root cause for the
valve malfunction to a set of improper tightened bolts, eventually causing an O
-ring to burst. The root cause concludes an assembly error on the valve supplier
production line. The assembly error was not detected by valve supplier quality
control nor by the trailer suppliers' quality inspection. Mitigating actions
will be implemented at both trailer supplier and valve supplier to eliminate
similar situations and implement best market praxis. These include updated
procedures for continued verification of tightness throughout the lifetime of
the trailers.

To verify that the fault is not systematic a campaign is initiated in close
cooperation between Everfuel, trailer supplier and valve supplier. Following a
successful campaign, the trailers will sequentially be refilled and redeployed
to hydrogen stations in a prioritised order. Everfuel expects to provide an
estimated plan for the restart of our hydrogen distribution and hydrogen
stations by Monday 3 July.

Everfuel and our suppliers are sorry for the inconvenience that the situation
cause our customers. For most recent updates on trailers and stations follow:

Everfuel will also report further on the incident as part of the Q2 report on
august 30[th].
