Aether
Confidential
Imagine a future where
anything can be built atom
by atom

Confidential
Aether is building
this future by
designing molecular
assemblers
3
Modern molecular manufacturing is limited in the
products that can be built
Traditional scale-up is capex intensive, slow to
scale and damaging to the environment
Fixing this requires moving from brute force
chemistry to precisely assembling products
at the atomic scale
Confidential
Biology gave us a start, but we need to
push beyond what nature invented
proteins are nanoscale
machines that
manufacture molecules
from simple building
blocks
Current protein technologies
are limited to catalyzing
natural-like reactions
This limits the use of
proteins to applications
where the final product
or reaction is similar to
what already exists in
nature
Natural

Current protein application space

Confidential
We have to build
searchable indexes
of proteins
5
Every protein can catalyze thousands of diverse
non-natural reactions
However existing technologies test protein
designs against only a few reactions at a time
Building searchable indexes requires empirically
testing millions of protein - reaction combinations
Confidential
Aether is building
these indexes with
proprietary
technology
6
Aether’s platform runs miniaturized enzymatic
experiments on high density 1536 micro-plates
to reduce per sample cost
Acoustic and piezoelectric printers rapidly print
thousands of different molecules in order to
empirically test proteins at scale
Reactions are spotted onto metal chips and ionized
with UV lasers to maximize data rate per chip
Confidential
Enabling our
platform to generate
datasets of
unprecedented size
and diversity
7
Ultra-High Throughput: >20,000 samples/day
per laser, 20X faster than state of the art
Hypothesis Free Data: Proprietary screening
technology can detect over 10,000 different
reactions per screen
Scalability: Up to 10X lower per sample cost
through miniaturization and at 50X lower CapEx
than comparable tech
Confidential
These indexes help
Aether build
molecular product
lines with unique
properties
8
Detoxifying our drinking water supply
from harmful forever chemicals
Synthesizing completely new materials
with extraordinary strength to weight ratios
Extracting high value metals from new
sources accelerating the electrification of the
global economy
Confidential
Building these products requires overcoming
2 technological challenges
9
Reaction yield
isn't optimized for
scale
Once the product can be made in
small quantities, the protein yield
must be boosted to industrially
relevant conditions in order to
manufacture the final product
economically
No catalyst for
desired reaction class
Creating novel molecular
products requires identifying
proteins catalyzing new
reaction types that are either
impractical or impossible via
other conventional methods
Confidential
Aether’s technology creates breakthrough
solutions to both challenges
PROTEIN INDEXING PROTEIN OPTIMIZATION
10
Aether’s multi-parametric
optimization algorithms can
rapidly improve newly identified
reactions under industrially
relevant conditions, enabling
scale-up of new molecular
products
Aether can index proteins
against over 1000X more
molecules than conventional
technologies, enabling rapid
identification of new
reaction types
Confidential
We’ve only just
started indexing and
already identified
new reaction types
for 3 product lines
1
1
We’ve demonstrated the capability to screen over
30,000 molecules against individual proteins
Over 1000X more functional labels per protein
than state of the art screening technologies
protein leads identified for defluorination,
antiviral manufacturing, and aramid
polymerization, all forming potential novel IP
Aether’s Indexes enable the identification
of new reaction types for unique product
lines
PROTEIN INDEXING PROTEIN OPTIMIZATION
* new reaction type: patentable biocatalytic reaction between a specific protein and substrate(s) in which a specific type of bond change occurs
Confidential
And we can
optimize proteins to
industrial spec in
under 6 months protein identified during indexing chosen as starting
point for optimization
Algorithms combined with expert systems ran 15
iterations over 4 months, exceeding 6 month targets
Demonstrated 64X product yield improvement and
190X enantioselectivity improvement in 4 months

Our go to market strategy is designed to
address 3 main challenges
13
Disappointing
economics at
scale
Long development time,
incremental performance/lack of
green premiums and small
margins have plagued synbio
products with disappointing
economics when they finally reach
the market
Time and cost to
design and deploy
products
Companies can spend 3+ years
trying to develop new molecules
and spend $15M or more before
even attempting to scale
manufacturing
Identifying new
molecular
products
Identifying new and interesting
molecular products from the space
of possible molecules can be like
finding a needle in a haystack
Confidential
We derisk our
product lines by
mining our indexes
for novel and
proprietary
reactions
14
Aether simplifies searching for new molecular
products by mining our indexes for novel
reaction types on valuable molecular
classes
Every indexed reaction can be the foundation for
novel IP owned by Aether
Aether’s reaction-first approach reduces
early product R&D risks and ensures
sustainable competitive advantage
Confidential
Our platform allows
us to develop and
derisk products
rapidly, and at low
cost
15
5+ product lines can be started per year
Standardized expression system and biocatalysis
(instead of fermentation) allow for fast and low
risk process scale up
Lower per-program costs and rapid
timelines allow Aether to fail fast and
rapidly iterate to new molecular products
Confidential
And we focus on
applications where
we can capture the
most value
16
High Impact: We only work on applications that
can positively impact the lives of millions of human
beings
Differentiated Value: We filter applications by
whether the product enables radically new
properties, not marginal improvements to existing
products
Uniqueness: We only tackle programs where the
final product is impossible without Aether’s
proteins, enabling Aether to own more of the
value generated
Focusing on applications where our proteins
are the key enabling factor will allow Aether
to capture a large share of the value created
Confidential
We’ve already started on 3 Aether product
lines
1: Applying defluorination proteins to
degrade forever chemical in our
environment (soil and drinking water)
2: Applying novel polymerases to
design and build decarbonized
ultra-high performance materials with
unprecedented properties
3: Applying novel metal binding
proteins to extract high value metals
from previously inaccessible sources
Commercial strategy Potential total addressable market
Co-develop with partners working on
filtering and concentration of PFAS for
municipal water utilities or in soil. This
solution will enable them to finally
provide a full solution to PFAS removal
Develop a portfolio of minimum viable
products to validate specs, then license
products and manufacturing process to
advanced materials manufacturers
Develop and build pilot scale metal
refineries to validate both low cost and
generalizable metal extraction, then
either license or vertically integrate
depending on metal and margins.

Perfluorinated molecules (PFAS) do not degrade
in nature. They are present in almost all the
drinking water globally, and PFAS exposure is
associated with several types of cancer and
autoimmune disorders
18
The only method to degrade PFAS today requires
ultra-high pressures/temperatures, making it
completely impractical for the drinking water supply
Aether has developed the first novel proteins to
degrade PFAS molecules efficiently and
sustainably
1
With our novel
defluorinating
proteins, we will
degrade toxic
forever chemicals
(PFAS) from our
drinking water
Confidential
High Complexity Polymers (HCPs) with 2+
monomers cannot be synthesized* with modern
chemistry
19
* in any meaningful quantities, technically you could make ng level quantities with additive synthesis
Additionally, current approaches are highly energy
intensive with temperatures ranging from 0-400 ℃
for manufacturing polymers
Aether is developing protein that would enable the
manufacturing of HCPs with the potential for
dramatically greater tensile strength and
much better ballistic performance
proteins would also enable the decarbonization
of existing and future high performance
polymers

With our novel
aramidase
proteins, we will
design and build
previously
impossible high
tech materials
Confidential
15% of global lithium reserves are locked in
inaccessible brines in North America
20
Aether’s peptide technology could 30X domestic
production of lithium.
Aether is developing novel proteins that can bind to
and mineralize lithium even at low concentrations
with little to no pre-processing.
This technology will enable the direct
production of battery grade lithium from
US based sources at industry beating
cost.

With our novel metal
binding proteins, we
will dramatically
increase the
production of key
strategic metals in
the US, at
competitive cost
