Pryme - Trading Update

Rotterdam, October 20th, 2025

Pryme (the "Company") has not yet resumed operations at its pilot plant, Pryme
One, since the August 25th, 2025, shutdown caused by a leak in a reactor seal.
The necessary repairs have required significant lead times for both component
deliveries and execution. The discovery and repairs of additional issues that
ultimately led to the failure of the seals have further delayed the repair work.
Currently, Pryme expects production at Pryme One to resume in the second half of
October 2025.

Pryme provides the following trading update with information regarding the Pryme
One production status, further perspective on the expected production
capacities, status of renegotiating Pryme's supply contract(s), Pryme's
liquidity status and need for funding, and updates on selected other items.

Pryme One Production Status

In Q4, 2024, Pryme issued multiple trading updates where the most significant
information was the reduction in the expected annual capacity of Pryme One from
around 30,000 to around 17,000 tons of pyrolysis oil. Such an estimation of the
Pryme One production capacity was based on observations at that time based on
the 2024 production runs. Expected plant availability, feeding time of the
reactor, reaction rates, feedstock to oil yields and other variables were taken
into consideration when estimating the overall Pryme One production capacity.
Many of these assumptions were based on data acquired at low feed rates.
Consequently, Pryme developed a testing plan to improve the accuracy of and
verify the capacity estimates. Unfortunately, the execution of the testing plan
to verify the assumptions for the expected annual production capacity of Pryme
One of 17,000 tons of pyrolysis oil has been significantly delayed due to
process and mechanical problems related to the reactor. 

Despite the slow progress of the testing program, Pryme has collected valuable
additional production data and has also improved some of the operating
parameters of Pryme One. During the production runs in July 2025, the achieved
feeding time of the reactor and feedstock to oil yield performance were all more
favorable than assumed for the 17,000 annual capacity estimates. 

Unfortunately, one of the most significant operating parameters, the reaction
rate in the reactor, was significantly below the assumed performance level. This
is due to a scaling buildup in the reactor that leads to a lower heat exchange
rate which again reduces the conversion rate of the reactor. Pryme is working on
solutions to resolve this problem through both mechanical- and process-oriented
solutions. The scaling problem has a strong influence on the overall estimated
capacity of Pryme One that unless resolved will lead to a capacity reduction of
around 50% compared to the earlier estimates to around 7,500 tons of pyrolysis
oil annually. The testing program is focusing on resolving the scaling issue and
is expected to deliver results within the next three months.

For Pryme's future plants, the scaling problem is not expected to have a strong
impact as the overall reaction rate can be improved by adding additional
reactors or using different reactors. For Pryme One, this is more difficult due
to lead times and space constraints in the current installation.

In addition to the reactor process problems, mainly the scaling problem, Pryme
has faced significant mechanical problems with the reactor which has led to the
plant availability being below the assumed values. This is caused by problems
with seal assemblies, bearings and bushings, the char dump valve and the failure
of individual heating elements. In combination, these issues have caused the
installation to be non-operational for 89% of the time over the last three
months. Pryme is working on solutions to these mainly mechanical issues which
are very time-consuming and further aggravated by a reactor design that does not
facilitate serviceability.

The testing program of Pryme One is expected to continue until the end of Q1
2026, at which time the production is expected to become more stable at higher
levels than achieved to date. The testing program focuses more on improving the
processes and solving the mechanical problems rather than maximizing production
output as Pryme's main priority is to develop a technology which can
successfully be applied to its future plants. Thus, the expected production
levels for Q4 2025 and Q1 2026 are estimated to be 600-1,000 tons of pyrolysis
oil for each of those quarters. As a reference, the Q3 2025 pyrolysis production
amounted to 468 tons of pyrolysis oil.

Please note that the above production ambitions and further financial
implications of the performance of the Company are not intended as a guidance to
Pryme's future performance but rather is intended to inform the market of
Pryme's operational ambitions and plans for Q4 2025 and Q1 2026.

Pryme Two Status

As noted in the Pryme One Production Status section, the expected production
capacity of Pryme Two is not projected to be affected by the lower capacity
observed to date in Pryme One due mainly to the low uptime and scaling problems
with Pryme One's reactor. The reason for this is that if no other alternatives
are found, additional reactor capacity may be added to compensate for this. If
additional reactors need to be incorporated into Pryme Two, this would increase
the overall capital expenditures. 

The Company assumes that Pryme Two will have an overall annual production
capacity in the range of 40,000-60,000 tons of pyrolysis oil. At that expected
Pryme Two overall capacity, the Company does not expect the EBITDA estimates per
ton of oil produced to change significantly compared to what was published in
the Company's investor presentation on 30th January 2025.

Sales Contract Renegotiation

As mentioned in earlier trading updates, quarterly reports and investor
presentations, Pryme has sought to renegotiate certain elements of its main
sales contract. These negotiations have now been completed. The key elements
that were renegotiated are pyrolysis oil pricing and specifications. 

Liquidity Status & Need for Funding

At the end of Q3 2025, Pryme's cash balance amounted to around EUR4.7 million. The
cash burn rate in Q3 was around EUR4.6 million. It is expected that the Q4 2025
and Q1 2026 cash burn rates will amount to EUR3.3 million and EUR4.3 million,
respectively, before the cash flow is expected to improve somewhat in Q2 2026
due to higher levels of pyrolysis oil production as per the plan. Although the
production volumes are expected to increase in Q4 2025 and Q1 2026, the Company
does not expect this to have significant effects on cash flow.

For Pryme to be funded for the period until the end of Q1 2026, additional
funding of around EUR5-6 million is required. Such funding would need to be
completed before the end of November 2025. 

The Company does not expect to be cash flow positive from Q2, 2026 onwards.
However, Pryme does expect to have improved the performance of Pryme One and to
have collected additional valuable production data by the end of Q1 2026. The
Company believes this will make it feasible to seek additional funding for the
period after Q1 2026 at that stage at terms expected to be favorable compared to
those that can be obtained before November 2025.

These revised cash flow estimates represent a deterioration versus earlier
estimates. This is mainly due to the slower increase in production volumes,
primarily triggered by the delays due to the reactor problems described earlier.
That leads to higher expected funding needs than previously estimated.

The Company is currently in the process of seeking additional funding as per the
indicated amounts and timeline.
