Full Press Release Details
advancing commercial readiness with profound production metrics on initial NCT pilot run
Angeles, CA -- January 29, 2026 -- Today, eXoZymes Inc. (NASDAQ: EXOZ) ("eXoZymes") - a pioneer of AI-enhanced enzymes that
can transform sustainable feedstock into nutraceuticals and new medicines - reported detailed downstream performance results from its
recently completed 100-liter pilot production run of NCT. The results expand upon the previously announced 100 scale-up milestone
and provide new data demonstrating manufacturability, material recovery, and product quality at commercially relevant scale.
completion of the pilot run and product isolation and purification, eXoZymes achieved approximately 99% reaction conversion, 91% process-
recovery, and a 90% isolated yield, resulting in 535 grams of isolated NCT. Final product purity was measured at 99.6%, based on post-isolation
analytical characterization. Together, these metrics provide a full, end-to-end view of process performance spanning reaction, isolation,
makes this initial NCT pilot run profound is how counter to conventional experience these results are. In most biological systems, performance
typically degrades as you scale - reactions become harder to control, yields drop, and variability increases. With our AI-enhanced enzymes
- exozymes - we see the opposite trend." states co-founder of eXoZymes and VP of Development, Paul Opgenorth, PhD, and continues,
"At very small laboratory scale, where cell-free reactions are usually developed and optimized, performance can actually be
the weakest. It improves at the one-liter scale, and this scaled run at 100 liters further reinforces that the system benefits from operating
at larger volumes. Seeing that behavior carry through to high recovery, isolated yield, and pharma-grade purity supports that exozymes
represent a fundamentally different and more scalable biomanufacturing paradigm compared to existing approaches."
a NCT tech transfer package, the pilot production was executed by Cayman Chemical, which independently operated the cell-free
reaction, downstream processing, isolation, and analytical confirmation. This marks the first time the exozyme-based biomanufacturing
process has been run end-to-end by an external partner, demonstrating protocol transferability and operational robustness.
Lead of Biosolutions and R&D Services, Adrian Br ckner, PhD, adds, "What stood out to me in this run was not just the
impressive final performance numbers, but how straightforward and reliable the process proved to be under real operating conditions.
The reaction was executed using a written, step-by-step protocol by an external team, and it performed exactly as intended. From a process
perspective, that level of consistency - combined with high recovery, isolated yield, and purity at this scale - gives us confidence
that the system is not only scalable, but operationally robust and well suited for continued manufacturing development. Importantly,
this successful production of more than half a kilogram of pharma-grade purity NCT means that we're now ready to share formulation
samples with relevant partners."
has historically been difficult to supply at scale in purified form. Cell-based production methods commonly co-produce N-trans-feruloyltyramine
(NFT), a closely related compound that has been reported in the scientific literature to exhibit different activity profiles from NCT
in certain in-vitro and preclinical research settings, which can complicate interpretation when both compounds are present. Because of
their close structural similarity, separating NFT from NCT is also costly. The exozyme-based process avoids these limitations, enabling
direct production of highly pure NCT without co-production challenges.
ahead, eXoZymes expects 2026 to focus on establishing a commercial NCT supply chain, expanding production volumes, forming strategic
partnerships, and finalizing commercial technology-transfer packages. These efforts are expected to focus on improving manufacturing
efficiency and scalability as eXoZymes and NCTx evaluate pathways toward sustainable commercial economics.
can be shipped to partners
With isolated high-purity NCT now produced at pilot scale, eXoZymes is actively engaging with partners interested in formulation development,
product validation, and application-specific testing. The availability of high-purity material enables partners to move beyond feasibility
studies and into hands-on evaluation under relevant conditions. Companies seeking to explore potential use cases, assess performance,
or initiate collaborative development discussions are invited to contact eXoZymes to request samples and discuss next steps, right here:

are advanced enzymes enhanced through AI and bioengineering to thrive in a bioreactor without using living cells. Exozymes can replace
toxic petrochemical processes and inefficient biochemical extraction with sustainable and scalable biosolutions that transform biomass
into essential chemicals, nutraceuticals and medicines.
freeing enzyme-driven chemical reactions from the limitations imposed by cells, exozyme biosolutions eliminate the scaling bottleneck
that has hampered commercial success in the synthetic biology (SynBio) space, making exozymes the next generation of biomanufacturing.
the company, eXoZymes Inc., has introduced "exozymes" as a scientific concept, they are not trademarking the concept, as
they view it as a new nomenclature for wide adoption for this next generation of biomanufacturing that eXoZymes aims to pioneer and be
the market leader of.
