Sustainable Manufacturing remains the core foundation of the company. Our 
high-performance  enzymes  enable  our  customers  to  reduce  the  cost  and 
increase  the  sustainability  of  product  manufacturing  through  higher  yields, 
less  energy  usage  and  lower  waste  generation.  This  segment  continues  to 
represent the majority of our revenues.

Our  pipeline  of  enzyme  catalysts  enabling  small  molecule  pharmaceutical 
processes continues to expand and remains a core driver of long-term growth 
for the company. In 2021, we executed on our largest annual product sale to 
Pfizer  for  one  of  our  proprietary  enzymes  to  be  used  in  the  manufacture  of 
their COVID-19 antiviral therapeutic. This project is expected to not only drive 
significant  growth  for  the  company  this  year  and  beyond,  but  also  provides 
tangible evidence of the critical impact our products can have on the health of 
people and the planet by enabling rapid and efficient manufacturing processes. 

Continuing  our  well-established  work  with  Merck’s  Januvia®  (sitagliptin),  we 
announced new multi-year agreements to extend our long-standing sitagliptin 
business into its generic chapter. These agreements include an extension of 
our enzyme supply contract with Merck through at least the end of 2026, as 
well  as  an  innovative  tri-party  relationship  with  Almelo  Private  Ltd.  and  RC2 
Pharma Connect LLC for the enzymatic production of low cost sitagliptin for 
the generic market. 

In  the  food  and  beverage  space,  we  expanded  the  research  collaboration 
and  entered  into  an  exclusive  supply  agreement  with  Kalsec,  Inc.  for  a  novel 
enzyme to produce a clean-label beverage ingredient, their newest natural hop 
acid. The new enzyme was engineered for improved functionality, stability, and 
efficiency, delivering consistent hop characteristics and taste that offer unique 
advantages for beverage products.

We also extended our partnership with Tate & Lyle to enhance the production 
of two new sweeteners. New enzyme variants, which replace existing Codexis 
enzymes on our two sweetener product collaborations with Tate & Lyle (DOLCIA 
PRIMA®  Allulose  and  TASTEVA®  M  Stevia  Sweetener),  will  enable  additional 
improvements  in  process  productivity  and  economics,  further  reducing  the 
already highly competitive cost of goods on the two products. 

We continue to invest in broadening the reach of our technology and products 
to  wide-ranging 
increasingly  targeting  new  customer 
segments  and  expanding  our  capacity  and  capability  to  both  improve  and 
economically produce enzymes in multiple organisms – a key requirement for 
success in industrial biotechnology.

Life Science Tools

Engineered  enzymes  enable  value  creating  performance 
improvements in genomics workflows, DNA and RNA synthesis 
and  numerous  other  life  science  applications.  To  date,  we  have 
launched three enzymes to address challenges for high-growth 
market  segments:  Codex®  HiFi  Hot  Start  DNA  polymerase  for 
next  generation  sequencing  (NGS)  library  prep  and  diagnostic 
molecular  assays;  Codex®  HiCap  RNA  polymerase  for  the 
manufacture of mRNA therapeutics; and, most recently, Codex® 
HiTemp  reverse  transcriptase  for  one-step  RT-qPCR  assays. 
We continue to invest significantly in Life Science Tools, both in 
our  own  program  and  in  partnered  programs,  to  accelerate  the 
cadence of our product launches. 

In late 2021, to address the market demand for viral diagnostics 
such  as  SARS-CoV-2  nucleic  acid  amplification  tests  and  in 
response  to  the  well-documented  challenges  faced  in  handling 
clinical  samples,  we  commercialized  Codex®  HiTemp  reverse 
transcriptase for use in one-step RT-qPCR assays. This enzyme 
is specifically engineered for enhanced thermostability to tackle 
complicated  RNA  structures  and  is  optimized  for  improved 
robustness  to  address  obstacles  such  as  sample  degradation, 
stability  at  room  temperature,  varying  pH  conditions,  and  the 
presence of impurities. 

Codexis  and  Molecular  Assemblies,  Inc.  (MAI)  are  established 
partners,  collaborating  to  revolutionize  DNA  production  using 
enzymatic synthesis. Since mid-2020, we have been applying our 
technology to improve the enzymes that are critical for DNA chain 
extension in MAI’s industrial scale manufacturing process. MAI has 
been leveraging Codexis’ highly engineered enzyme variants in its 
workflows  to  drive  process  performance  and  economics  to  the 
levels  required  for  successful  commercialization.  In  November 
2021,  Codexis  and  Casdin  Capital  invested  a  combined  $10 
million in the Series B funding round of MAI to accelerate its novel 
enzymatic DNA synthesis technology toward commercialization. 
Codexis  contributed  $7  million  of  this  investment,  becoming 
MAI’s second largest shareholder; this investment comes on top 
of previous investments by Codexis.

Biotherapeutics

We are leveraging our CodeEvolver® technology platform to improve 
multiple  protein  properties  in  parallel,  allowing  us  to  rapidly  build  and 
advance  a  high-value  pipeline  of  oral  enzyme  therapy  and  gene 
therapy candidates with the goal of addressing unmet patient needs. 
Our  current  focus  is  on  discovering  safe  and  efficacious  GI-active 
enzymes and transgenes for treatment of Inborn Errors of Metabolism 
(IEMs)  and  other  metabolic  diseases.  Our  application-focused  high 
throughput screens generate large data sets that we analyze with our 
bioinformatics  software,  enabling  us  to  generate  enzymes  uniquely 
designed for a specific therapeutic indication.

Two of our therapeutic enzyme candidates are in Phase 1 clinical trials. 
Our first Codexis-discovered candidate, CDX-6114, is being advanced 
by Nestlé Health Science for potential treatment of phenylketonuria. 
Our second clinical program, CDX-7108, is being assessed as potential 
treatment for exocrine pancreatic insufficiency (EPI) and is also being 
advanced  in  partnership  with  Nestlé  Health  Science.  CDX-7108  is  a 
lipase variant specifically engineered to overcome the limitations of the 
current  standard  of  care:  traditional  pancreatic  enzyme  replacement 
therapy  (PERT).  EPI  is  a  debilitating  condition  of  the  GI-tract  that 
is  caused  by  conditions  that  impair  pancreatic  function,  such  as 
pancreatitis,  pancreatic  cancer,  Crohn’s  disease,  celiac  disease,  and 
cystic  fibrosis.  CDX-7108  was  specifically  engineered  to  be  highly 
stable in the acidic conditions in the stomach and resistant to proteases 
in the upper intestines.

Our  wholly  owned  enzyme  therapy  programs  also  moved  forward 
in  2021.  Pre-clinical  data  on  CDX-6512  for  the  treatment  of 
homocystinuria (HCU) and enzyme variants for the treatment of maple 
syrup urine disease (MSUD) were presented at the 14th International 
Congress  of  Inborn  Errors  of  Metabolism  (ICIEM)  2021.  In  January 
2022,  the  FDA  granted  orphan  drug  designation  and  rare  pediatric 
disease designation for CDX-6512 for HCU. CDX-6512 is currently in 
IND-enabling studies.

We expanded our strategic collaboration and license agreement with 
Takeda for the research and development of an additional gene therapy 
for a lysosomal storage disorder, bringing the total number of programs 
under the agreement to four. To date, we have generated novel genetic 
sequences  that  encode  more  efficacious  enzymes  for  the  potential 
treatment  of  Fabry  and  Pompe  Diseases,  as  well  as  an  undisclosed 
blood factor deficiency.

Letter to Shareholders

Dear fellow shareholders, partners and employees: 

I am delighted to report that Codexis delivered another year 
of  exceptional  performance.  Total  revenue  for  2021  grew 
52%, year-over-year, to $105 million, up from $69 million in 
2020.  Product  revenue  more  than  doubled  to  $71  million 
in  2021,  up  from  $30  million  in  2020,  and  product  gross 
margin  reached  a  new  high  of  69%.  Over  the  past  year,  we 
continued to diversify our customer base with 30 customers 
contributing  over  $200,000  in  revenue  in  2021,  twelve  of 
these contributed over $2 million in revenue.

Beyond the financials, I am grateful for the commitment our 
employees  demonstrated  to  our  core  mission  and  vision: 
to  create  differentiated  enzymes  to  improve  the  health  of 
people and the planet. 

In  our  Biotherapeutics  business,  we  now  have  a  pipeline  of 
over a dozen programs and we are increasingly progressing 
selected  assets  into  clinical  development  on  our  own  to 
enhance their value for Codexis shareholders. This requires 
investment  on  a  product-by-product  basis  and  greater 
investment  to  grow  the  capacity  and  capabilities  of  the 
organization.  We  believe  strongly  in  the  reward  associated 
with  these  investments  and  expect  to  advance  several 
candidates toward clinical studies over the coming few years.

We  are  thrilled  to  have  entered  the  clinic  in  2021  with 
CDX-  7108  –  a  potential  treatment  for  exocrine  pancreatic 
insufficiency, which is co-owned with Nestlé Health Science. 
This is the second Codexis-designed therapeutic candidate
to  enter  Phase  1  clinical  trials,  after  CDX-6114  for  the 
potential treatment of phenylketonuria, which is now licensed 
to Nestlé Health Science. Two oral enzyme therapy programs 
co-owned with Nestlé Health Science and three self-funded
programs  are  advancing 
in  research  and  development.
Our  efforts  in  gene  therapy  have  also  made  tremendous
progress.  Our  collaboration  with  Takeda  to  advance  novel
gene  therapies  for  treatment  of  rare  diseases  expanded
to  four  programs  during  2021,  and  Codexis  is  generating
novel gene sequences to encode enzyme variants targeting 
enhanced efficacy by increasing activity, stability, and cellular 
uptake. Takeda is leveraging our improved transgenes with its 
gene therapy capabilities to develop novel candidates for the 
treatment of rare genetic disorders.

Our Sustainable Manufacturing business demonstrated step-
out growth in 2021, driven in large part by our ability to meet 
the  substantial  needs  of  Pfizer  with  one  of  our  proprietary 
enzymes to manufacture a critical intermediate for their 

new,  oral  COVID-19  antiviral  treatment.  We  are  pleased 
with the speed at which we were able to quickly scale up our 
supply chain and manufacturing partners in 2021 in order to 
support such a meaningful endeavor. We achieved multi- ton 
production of this enzyme within just a few months, enabling 
us to meet demand for tens of millions of treatment courses 
in the first half of 2022.

We  have  also  positioned  ourselves  well  for  the  upcoming 
generic  chapter  of  sitagliptin  by  extending  our  enzyme 
supply  agreement  with  Merck  and  establishing  a  multi-year 
agreement  with  Almelo  and  RC2  as  our  first  step  into  the 
generic  sitagliptin  market.  In  addition,  enzymes  sales  to 
other  innovative  pharmaceutical  customers  grew  in  2021, 
with three products using our enzymes achieving important 
regulatory approval milestones last year.

In  adjacent  markets  such  as  food  &  nutrition  and  industrial 
applications, we announced an expanded collaboration with 
Kalsec,  a  leading  producer  of  natural  extracts,  colors  and 
food  protection  for  the  food  and  beverage  industry.  We 
continue to serve Tate & Lyle in their production of low caloric 
sweeteners,  DOLCIA  PRIMA® Allulose  and  TASTEVA® M 
Stevia, and demand for our enzymes for production of these 
commercialized  food  ingredients  increased  meaningfully  in 
2021.  Our  ability  to  sustainably  manufacture  high-volume, 
non-pharmaceutical products is a long-term value driver for 
Codexis and has been increasingly recognized in the market 
by a growing number of partners.

In  our  exciting  and  dynamic  Life  Science  Tools  business, 
we  achieved  first  commercial  sales  on  two  key  products 
-  Codex® HiFi Hot  Start  DNA  Polymerase  for  genomic 
applications and  Codex®  HiCap  RNA  polymerase for mRNA 
production.  Our  latest  Life  Science  Tools  enzyme,  Codex®
HiTemp  Reverse  Transcriptase,  specifically  engineered  with 
improved  sensitivity  and  inhibitor  resistance  for  use  in  RT-
qPCR  for  RNA-based  disease  detection,  launched  in  the 
fourth quarter.

The partnership between Codexis and Molecular Assemblies, 
Inc.  is  also  making  great  strides,  bringing  the  disruptive 
enzymatic approach to DNA synthesis closer to reality. Given 
our  confidence,  both  in  the  partnership  and  in  the  market 
opportunity,  we  increased  our  equity  stake  in  Molecular 
Assemblies,  investing  $7  million  in  September  2021,  and 
becoming  their  second  largest  shareholder  in  the  process.

Molecular Assemblies. It is exciting to leverage our enzyme 
engineering  and  product  supply  capabilities  to  access 
downstream  value 
in  the  fast-growing  DNA  synthesis 
marketplace via these strategic moves.

To  support  this  rapid  business  growth,  and  to  continue 
investing  for  future  value  creation,  we  grew  our  employee 
base  by  over  40%  in  2021  and  added  several  strategic 
positions  to  strengthen  our  leadership  and  to  improve 
capacity  and  productivity.  Codexis  maintained  strong 
momentum throughout the year, executed on several high 
value opportunities in pharmaceuticals, food ingredients and 
life science tools, and advanced our second drug candidate 
into  the  clinic.  2021  was  a  very  strong  year  for  Codexis 
across all of our target sectors, and we have a bright outlook 
for 2022.

On  behalf  of  Codexis’  leadership  team,  employees,  and 
Board of Directors, I thank you for your continued support.

Letter to Shareholders

Dear fellow shareholders, partners and employees: 

I am delighted to report that Codexis delivered another year 
of  exceptional  performance.  Total  revenue  for  2021  grew 
52%, year-over-year, to $105 million, up from $69 million in 
2020.  Product  revenue  more  than  doubled  to  $71  million 
in  2021,  up  from  $30  million  in  2020,  and  product  gross 
margin  reached  a  new  high  of  69%.  Over  the  past  year,  we 
continued to diversify our customer base with 30 customers 
contributing  over  $200,000  in  revenue  in  2021,  twelve  of 
these contributed over $2 million in revenue.

Beyond the financials, I am grateful for the commitment our 
employees  demonstrated  to  our  core  mission  and  vision: 
to  create  differentiated  enzymes  to  improve  the  health  of 
people and the planet. 

In  our  Biotherapeutics  business,  we  now  have  a  pipeline  of

ITEM 1. BUSINESS 

COMPANY OVERVIEW 

We discover, develop and sell enzymes and other proteins that deliver value to our clients in a growing set of industries. We 

view proteins as a vast, largely untapped source of value-creating products, and we are using our proven technologies, which 
we have been continuously improving since our inception in 2002, to commercialize an increasing number of novel enzymes, 
both as proprietary Codexis products and in partnership with our customers. 

We are a pioneer in harnessing computational technologies to drive biology advancements. Since 2002, we have made 
substantial investments in the development of our CodeEvolver® protein engineering technology platform, the primary source 
of our competitive advantage. Our technology platform is powered by proprietary, artificial intelligence-based, computational 
algorithms that rapidly mine the structural and performance attributes of our large and continuously growing library of protein 
variants. These computational outputs enable increasingly reliable predictions for next generation protein variants to be 
engineered, enabling time- and cost-efficient delivery of the targeted performance enhancements. In addition to its 
computational prowess, our CodeEvolver® protein engineering technology platform integrates additional modular 
competencies, including robotic high-throughput screening and genomic sequencing, organic chemistry and bioprocess 
development which are all coordinated to rapidly innovate novel, fit-for-purpose products. 

The core historical application of the technology has been in developing commercially viable biocatalytic manufacturing 
processes for more sustainable production of complex chemicals. It begins by conceptually designing the most cost-effective 
and practical process for a targeted product. We then develop optimized biocatalysts to enable the designed process, using our 
CodeEvolver® platform. Engineered biocatalyst candidates, numbering many thousands for each project, are then rapidly 
screened and validated using high throughput methods under process-relevant operating conditions. This approach results in an 
optimized biocatalyst that enables cost-efficient processes that are relatively simple to run in conventional manufacturing 
equipment allowing for efficient technical transfer of our processes to our manufacturing partners. This also allows for efficient 
technical transfer of our processes to our manufacturing partners. 

The successful embodiment of our CodeEvolver® protein engineering technology platform in commercial manufacturing 

processes requires well-integrated expertise in a number of technical disciplines. In addition to those competencies directly 
integrated in our CodeEvolver® protein engineering platform, such as molecular biology, enzymology, microbiology, cellular 
engineering, metabolic engineering, bioinformatics, biochemistry and high throughput analytical chemistry, our process 
development projects also involve integrated expertise in organic chemistry, chemical process development, chemical 
engineering, bioprocess development and fermentation engineering. Our integrated, multi-disciplinary approach to product and 
process development is a critical success factor for the Company. 

We initially commercialized our CodeEvolver® protein engineering technology platform and products in the manufacture 
of small molecule pharmaceuticals, which remains a primary business focus. Our customers, which include many large, global 
pharmaceutical companies, use our technology, products and services in their process development and in manufacturing. 
Additionally, we have licensed our proprietary CodeEvolver® protein engineering technology platform to global pharmaceutical 
companies enabling them to use this technology, in house, to engineer enzymes for their own businesses. In May 2019, we 
entered into a Platform Technology Transfer and License Agreement (the “Novartis CodeEvolver® Agreement”) with Novartis 
Pharma AG (“Novartis”). The Novartis CodeEvolver® Agreement (Codexis’ third such agreement with large pharma 
companies) allows Novartis to use our proprietary CodeEvolver® protein engineering platform technology in the field of human 
healthcare. 

As evidence of our strategy to extend our technology beyond pharmaceutical manufacturing, we have also used the 
technology to develop biocatalysts and enzyme products for use in a broader set of industrial markets, including several large 
verticals, such as food, feed, consumer care and fine chemicals. In addition, we are using our technology to develop enzymes 
for various life science related applications, such as next generation sequencing (“NGS”), DNA and RNA synthesis and other 
molecular biology research applications. In December 2019, we entered into a license agreement to provide Roche Sequencing 
Solutions, Inc. ("Roche") with our first enzyme for this target market: the Company’s EvoT4™ DNA ligase. In June 2020, we 
entered into a co-marketing and enzyme supply collaboration agreement with Alphazyme LLC for the production and co-
marketing of enzymes for life science applications including, initially, high-fidelity DNA polymerase, T7 RNA polymerase and 
reverse transcriptase enzymes. In June 2020, we also entered into a Master Collaboration and Research Agreement with 
Molecular Assemblies, Inc. ("MAI") (the “MAI Agreement”) pursuant to which we are leveraging our CodeEvolver® platform 

4 

 
technology to improve the DNA polymerase enzymes that are critical for enzymatic DNA synthesis. We anticipate completing 
an enzyme engineering project with MAI in the first quarter of 2022.  

We have been using the CodeEvolver® protein engineering technology platform to develop early stage, novel 

biotherapeutic product candidates, both in partnership with customers and for our own proprietary Codexis drug candidates. 
Our first program was for the potential treatment of phenylketonuria ("PKU") in humans. PKU is an inherited metabolic 
disorder in which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient. In October 2017, 
we entered into a Global Development, Option and License Agreement (the “Nestlé License Agreement”) with Societé des 
Produits Nestlé S.A., formerly known as Nestec Ltd. (“Nestlé Health Science”) to advance CDX-6114, our enzyme 
biotherapeutic product candidate for the potential treatment of PKU. In February 2019, Nestlé Health Science exercised its 
option to obtain an exclusive license to develop and commercialize CDX-6114. Also in October 2017, we entered into a 
strategic collaboration agreement with Nestle Health Science (“Nestlé SCA”) pursuant to which we and Nestlé Health Science 
are collaborating to leverage the CodeEvolver® platform technology to develop other novel enzymes for Nestlé Health 
Science’s established Consumer Care and Medical Nutrition business areas.  

In March 2020, we entered into a Strategic Collaboration and License Agreement (“Takeda Agreement”) with Shire Human 

Genetic Therapies, Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Company Limited (“Takeda”), for the research 
and development of novel gene therapies for certain disease indications, including the treatment of lysosomal storage disorders 
and a blood factor deficiency.  

BUSINESS SEGMENTS 

We manage our business as two business segments: Performance Enzymes and Novel Biotherapeutics. See Note 15, 
“Segment, Geographical and Other Revenue Information” in the Notes to the Consolidated Financial Statements set forth in 
Item 8 of this Annual Report on Form 10-K. 

Performance Enzymes 

We initially commercialized our CodeEvolver® protein engineering technology platform and products in the manufacture 
of small molecule pharmaceuticals and, to date, this continues to be our largest market served. Our customers, which include 
many large global pharmaceutical companies, use our technology, products and services in their manufacturing processes and 
process development. We have also used the technology to develop customized enzymes for use in other industrial markets. 
These markets consist of several large industrial verticals, including food, feed, consumer care, and fine chemicals. We also use 
our technology in the life sciences markets to develop enzymes for customers using NGS and PCR/qPCR for in vitro molecular 
diagnostic and molecular biology research applications, as well DNA/RNA synthesis and health monitoring applications. 

Novel Biotherapeutics 

We are also targeting new opportunities in the pharmaceutical industry to discover, improve, and/or develop biotherapeutic 

drug candidates. We believe that our CodeEvolver® protein engineering platform technology can be used to discover novel 
biotherapeutic drug candidates that will target human diseases that are in need of improved therapeutic interventions. Similarly, 
we believe that we can deploy our platform technology to improve specific characteristics of a customer’s pre-existing 
biotherapeutic drug candidate, such as its activity, stability or immunogenicity. Our first lead program was for the potential 
treatment of hyperphenylalaninemia (“HPA”) (also referred to as PKU) in humans. PKU is an inherited metabolic disorder in 
which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient. In October 2017, we 
announced a global development, option and license agreement with Nestlé Health Science to advance CDX-6114, our own 
novel orally administrable enzyme therapeutic candidate for the potential treatment of PKU. In July 2018, we announced that 
we had dosed the first subjects in a first-in-human Phase 1a dose-escalation trial with CDX-6114, which was conducted in 
Australia. The initiation of the trial triggered a $4.0 million milestone payment from Nestlé Health Science. The $1.0 million 
milestone payment that was triggered by the achievement of a formulation relating to CDX-6114 was received in February 
2019. In January 2019, we received notice from the U.S. Food and Drug Administration ("FDA") that it had completed its 
review of our investigational new drug application ("IND") for CDX-6114 and concluded that we may proceed with the 
proposed Phase 1b multiple ascending dose study in healthy volunteers in the United States. In February 2019, Nestlé Health 
Science exercised its option to obtain an exclusive, worldwide, royalty-bearing, sub-licensable license for the global 
development and commercialization of CDX-6114 for the management of PKU. As a result of the option exercise, we earned a 
milestone and recognized $3.0 million in revenues in the first quarter of 2019. Upon exercising its option, Nestlé Health 
Science assumed all responsibilities for future clinical development and commercialization of CDX-6114.

In October 2017, we separately entered into the Nestlé SCA with Nestlé Health Science pursuant to which we and Nestlé 

Health Science are collaborating to leverage the CodeEvolver® platform technology to develop other novel enzymes for Nestlé 
Health Science’s established Consumer Care and Medical Nutrition business areas. The term of the Nestlé SCA has been 
extended through December 2022.  

In January 2020, we and Nestlé Health Science entered into a development agreement pursuant to which we and Nestlé 

Health Science are collaborating to advance CDX-7108, a lead candidate targeting a gastrointestinal disorder, discovered 
through the Nestlé SCA, into preclinical and early clinical studies. During 2021, we, together with Nestlé Health Science, 
continued to advance CDX-7108 towards initiation of a Phase 1 clinical trial with the first subject being dosed in November 
2021.  

In March 2020, we entered into the Takeda Agreement with Takeda pursuant to which we are collaborating to research and 

develop protein sequences for use in gene therapy products for certain disease indications in accordance with the respective 
program plans for Fabry Disease, Pompe Disease, and an undisclosed blood factor deficiency. In March 2020, we received a 
one-time, non-refundable cash payment of $8.5 million. Of these programs, the Fabry disease program is the most advanced, 
with multiple sequences, including CDX-6311, which were provided to Takeda. We also provided sequences to Takeda for the 
Pompe program. In May 2021, Takeda elected to exercise their option to initiate an additional program for a certain undisclosed 
rare genetic disorder and we received the option exercise fee during the third quarter of 2021. 

RECENT DEVELOPMENT - PFIZER (PAXLOVID™) 

In the first and second quarters of 2021, we began to receive purchase orders from Pfizer, Inc. (“Pfizer”) for large 
quantities of our proprietary enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical intermediate for its 
proprietary active pharmaceutical ingredient, nirmatrelvir. Pfizer markets, sells and distributes nirmatrelvir, in combination with 
the active pharmaceutical ingredient ritonavir, as its PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets) product, which 
received emergency use authorization by the U.S. Food and Drug Administration (“FDA”) in late 2021 for the treatment of 
COVID-19 in humans. 

In 2021, we recognized approximately $34.5 million in revenue from the sale of quantities of CDX-616 to Pfizer. In 
addition, as of December 31, 2021, we have received additional purchase orders from Pfizer for delivery of a significant 
quantity of CDX-616 in 2022. We have received and currently expect to receive additional purchase orders from Pfizer for 
significant quantities of CDX-616 during the course of 2022 for delivery in 2022 and 2023. As of December 31, 2021, we have 
not yet executed a long-term purchase and sale agreement with Pfizer for CDX-616; with or without a long-term purchase and 
sale agreement, we currently expect that future orders for quantities of CDX-616 by Pfizer will continue to be based on the 
needs of Pfizer for quantities of CDX-616 and there will be no minimum purchase obligation on the part of Pfizer. 

BUSINESS UPDATE REGARDING COVID-19 

We are subject to risks and uncertainties as a result of the current COVID-19 pandemic. The COVID-19 pandemic has 
presented a substantial public health and economic challenge around the world and is affecting our employees, communities 
and business operations, as well as the U.S. economy and other economies worldwide. The full extent to which the COVID-19 
pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future 
developments that are highly uncertain and may not be accurately predicted, including the duration and severity of the 
pandemic, the prevalence of more contagious and or virulent variants such as the Delta and Omicron variants, and the extent 
and severity of the impact on our customers, new information that may emerge concerning COVID-19, the actions taken to 
contain it or treat its impact and the economic impact on local, regional, national and international markets. 

In the United States, the impact of COVID-19, including governmental orders (“Orders”) governing the operation of 
businesses during the pandemic, caused the temporary closure of our Redwood City, California facilities in 2020 and disrupted 
our R&D operations. R&D operations for several projects were temporarily suspended from mid-March 2020 through the end 
of April 2020 in accordance with these Orders. In May 2020, we re-initiated limited R&D operations and have ramped up 
operations such that we are currently utilizing our normal R&D capacity while following county, state and federal COVID-19 
guidance for the protection of our employees. Additionally, we resumed manufacturing at our Redwood City pilot plant in May 
2020. 

To date, we and our collaboration partners have been able to continue to supply our enzymes to our customers worldwide. 

However, we are dependent on our manufacturing and logistics partners and consequently, disruptions in operations of our 
partners and customers may affect our ability to supply enzymes to our customers. Furthermore, our ability to provide future 
research and development (“R&D”) services will continue to be impacted as a result of governmental orders and any 
disruptions in operations of our customers with whom we collaborate. We believe that these disruptions have had a minimal 

6 

 
 
impact on our revenue for the year ended December 31, 2021. The extent to which the pandemic may impact our business 
operations and operating results will continue to remain highly dependent on future developments, which are uncertain and 
cannot be predicted with confidence. 

Our future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable 

amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the impact of any initiatives or 
programs that we may undertake to address financial and operations challenges faced by our customers. The near-and-long term 
impact of COVID-19 to our financial condition, liquidity, or results of operations remains uncertain. Although some of the 
Orders that were enacted to control the spread of COVID-19 have begun to be scaled back and the vaccine rollout has 
expanded, surges in the spread of COVID-19 due to the emergence of new more contagious or virulent variants or the 
ineffectiveness of the vaccines against such strains, may result in the reimplementation of certain Orders, which could adversely 
impact our business. The extent to which the COVID-19 pandemic may materially impact our financial condition, liquidity, or 
results of operations in the future is uncertain. 

As a result of the COVID-19 pandemic we have received purchase orders from Pfizer for large quantities of our proprietary 

enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical intermediate for its proprietary active 
pharmaceutical ingredient, nirmatrelvir, used by Pfizer in combination with the active pharmaceutical ingredient ritonavir, as its 
PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets) product for the treatment of COVID-19 infections in humans. These 
purchase orders have had a substantial impact on our revenue in 2021.  

For additional information on the various risks posed by the COVID-19 pandemic, see “Risk Factors” set forth in Item 1A 

of this Annual Report on Form 10-K. 

OUR STRATEGY 

Our strategy is to grow our revenues, profits, and stockholder value by leveraging our CodeEvolver® protein engineering 

technology platform in the following ways: 

Licensing our CodeEvolver® protein engineering technology platform. We intend to continue to pursue opportunities 

• 
to license our CodeEvolver® protein engineering technology platform to third parties so they can create cost-saving 
biocatalyst solutions utilizing their own in-house protein engineering capability.  

•  Growing our pharmaceutical biocatalysts business. We intend to continue to pursue opportunities in the 
pharmaceutical market to use our protein catalysis products and services to reduce the costs for manufacturing small 
molecule drugs. We intend to increase the number of pharmaceutical customers and processes that utilize and benefit from 
our novel, cost-saving biocatalyst solutions.  

•  Creating and advancing novel biotherapeutic drug candidates. We intend to continue to pursue opportunities to apply 
our protein engineering capabilities to the creation and development of novel biotherapeutic drug candidates, both in 
partnership with customers and as proprietary Codexis drug candidates. We have also invested in research and development 
in an effort to generate additional early stage novel biotherapeutic candidates. 

•  Extending our biocatalysts and industrial enzymes business into new markets. We intend to continue to pursue 
opportunities to use biocatalyst products and services to reduce the costs and improve sustainability for manufacturing in 
markets such as food and food ingredients. We intend to increase the number of customers and industrial verticals that 
utilize and benefit from our novel performance enzyme solutions. 

•  Developing high-performance enzymes for use in diagnostic applications. We intend to offer high-performance 
enzymes to customers using NGS and PCR/qPCR for in vitro molecular diagnostic applications. 

In this Annual Report, the “Company,” “we,” “us” and “our” refer to Codexis, Inc. and its subsidiaries on a consolidated 

basis. 

OUR MARKET OPPORTUNITIES 

Pharmaceutical Market 

We believe the pharmaceutical industry represents a significant market opportunity for us and is our primary business 
focus. Pharmaceutical companies are in constant search for new drugs to offer to their customers, and are under significant 
competitive pressure both to reduce costs and to increase the speed to market for their products. To meet these pressures, 
pharmaceutical companies are discovering and developing novel protein-based drug products, as well as seeking manufacturing 
processes for their new and existing drugs that reduce overall costs, simplify production and increase efficiency and product 
yield, while not affecting drug safety and efficacy. Cost reduction is even more important to developers (known as innovators) 

7 

 
of patent-protected pharmaceutical products when the patents for those products expire and such innovators are forced to 
compete with manufacturers of generic drugs. 

The pharmaceutical product lifecycle begins with the discovery of new chemical entities and continues through preclinical 

and clinical development, regulatory review and approval, commercial scale-up, product launch, and, ultimately, patent 
expiration and the transition from branded to generic products. As innovators develop, produce and then market products, 
manufacturing priorities and processes evolve. Historically, innovators have focused on production cost reduction in the later 
stages of clinical development and have been reluctant to make process changes after a product has been launched. However, as 
pressures to reduce costs have increased, innovators have pursued cost reduction measures much earlier in the pharmaceutical 
product lifecycle and are increasingly looking for opportunities to improve their operating margins, including making 
manufacturing process changes for marketed products after the products have been launched if these changes can result in 
significant cost reductions. As a result, innovators are investing in new technologies, including our CodeEvolver® protein 
engineering technology platform, to improve their manufacturing productivity and efficiency or outsourcing the manufacture of 
their intermediates and active pharmaceutical ingredients ("API"). 

Our Solutions for the Pharmaceutical Market  

Small Molecule Manufacturing Cost Reduction 

Our pharmaceutical customers, which include many large global pharmaceutical companies, use our technology, products 

and services in their manufacturing processes and process development. Our CodeEvolver® protein engineering technology 
platform enables us to deliver solutions to our customers in this market by developing and delivering optimized biocatalysts 
that perform chemical transformations at a lower cost and improve the efficiency and productivity of manufacturing processes. 
We provide value throughout the pharmaceutical product lifecycle. Our products and services allow us to provide benefits to 
our pharmaceutical customers in a number of cost saving ways, including any - and sometimes all - of the following: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

reducing the use of raw materials and reagents;  

eliminating multiple steps in the manufacturing process; 

improving purity, productivity and yield;  

using water as a primary solvent;  

eliminating hazardous inputs;  

enabling the use of simple equipment and reducing the need for capital expenditure; 

reducing energy requirements;  

reducing the generation of chemical byproducts or waste; and 

reducing the need for late-stage purifications.  

Early in a pharmaceutical product’s lifecycle, pharmaceutical manufacturers can use our biocatalyst products and services 
to reduce manufacturing costs. If an innovator incorporates our products or processes into an approved product, we expect the 
innovator to continue to use our products or processes at least over the patent life of the marketed drug. 

Pharmaceutical manufacturers can also use our products and services to reduce manufacturing costs after a product is 
launched. At this stage, changes in the manufacturing process originally approved by the drug regulator may require additional 
regulatory review. Typically, pharmaceutical companies will only seek regulatory approval for a manufacturing change if 
substantial cost savings are realizable. We believe that the cost savings associated with our products may lead our customers to 
change their manufacturing processes for approved products and, if necessary, seek regulatory approval of the new processes 
which incorporate our biocatalyst products. Moreover, we believe these cost savings are potentially attractive to generics 
manufacturers, who compete primarily on price. 

In addition, manufacturing processes that utilize our biocatalysts can frequently enable processes that are more sustainable 
and environmentally friendly compared to alternative, traditional manufacturing approaches. This has led us to earn three U.S. 
EPA Presidential Green Chemistry Challenge awards for improved pharmaceutical manufacturing processes since we were 
founded. All three of these awards were associated with blockbuster drug products. 

Licensing Our CodeEvolver® Protein Engineering Technology Platform 

Licensing our CodeEvolver® protein engineering technology platform to pharmaceutical companies enables them to 
rapidly develop custom-designed enzymes that are highly optimized for efficient manufacturing processes. To date, we have 
entered into platform technology licensing agreements with each of GlaxoSmithKline Intellectual Property Development 

8 

 
Limited, a subsidiary of GlaxoSmithKline plc ("GSK"), Merck, Sharp & Dohme ("Merck") and Novartis Pharma AG 
("Novartis"), and we intend to continue to enter into license arrangements with third parties that will allow them to use our 
CodeEvolver® protein engineering technology platform to discover and develop novel proteins for their internal use.  

GlaxoSmithKline 

We entered into our first CodeEvolver® protein engineering Platform Technology Transfer, Collaboration and License 
Agreement (“GSK CodeEvolver® Agreement”) in July 2014 with GlaxoSmithKline Intellectual Property Development Limited, 
a subsidiary of GSK, pursuant to which we granted GSK a non-exclusive, worldwide license to use our CodeEvolver® protein 
engineering technology platform in the field of human healthcare for its internal development purposes. 

Under the GSK CodeEvolver® Agreement, we licensed and transferred our certain patents, patent applications and know-
how from our CodeEvolver® protein engineering technology platform to GSK, completing the transfer in April 2016. Under this 
agreement, we have the potential to receive contingent payments that range from $5.75 million to $38.5 million per project 
based on GSK's successful application of the licensed technology. We are also eligible to receive royalties based on net sales, if 
any, of a limited set of products developed by GSK using our CodeEvolver® protein engineering technology platform. 

The term of the GSK CodeEvolver® Agreement continues, unless earlier terminated, until the expiration of all payment 
obligations under the GSK CodeEvolver® Agreement. GSK can terminate the GSK CodeEvolver® Agreement by providing 90 
days written notice to us.  

In 2019, we received a $2.0 million milestone payment on the advancement of an enzyme developed by GSK using our 
CodeEvolver® protein engineering platform technology. In 2021, we received two additional milestone payments from GSK 
under the GSK CodeEvolver® Agreement. 

Merck  

In August 2015, we entered into a CodeEvolver® Platform Technology Transfer and License Agreement (the “Merck 

CodeEvolver® Agreement”) with Merck. The Merck CodeEvolver® Agreement allows Merck to use our proprietary 
CodeEvolver® protein engineering platform technology in the field of human and animal healthcare.  

Under the terms of the Merck CodeEvolver® Agreement, we granted to Merck an exclusive license under certain patents, 

patent applications and know-how from our CodeEvolver® protein engineering technology platform for the research, 
development and manufacture of novel enzymes for use by Merck in the chemical synthesis of therapeutic products owned or 
controlled by Merck ("Merck Exclusive Field") and a non-exclusive worldwide license to use the CodeEvolver® protein 
engineering technology platform to research, develop and manufacture novel enzymes for use by Merck in its internal research 
programs (“Merck Non-Exclusive Field”).  

Under the terms of the Merck CodeEvolver® Agreement, Merck paid us upfront technology transfer and license fees and 
milestone payments over the technology transfer period of 15 months from August 2015. We also have the potential to receive 
product-related payments of up to $15.0 million for each API that is manufactured by Merck using one or more enzymes that 
have been developed or are in development using the CodeEvolver® protein engineering technology platform during the 10-
year period that begins on the conclusion of the 15-month technology transfer period. These product-related payments, if any, 
will be paid by Merck to us for each quarter that Merck manufactures API using a CodeEvolver®-developed enzyme. The 
payments will be based on the total volume of API produced using the CodeEvolver®-developed enzyme. 

In September 2016, we completed the full transfer of the engineering platform technology. In October 2018, we entered 
into an amendment to the Merck CodeEvolver® Agreement whereby we amended certain licensing provisions and one exhibit. 
In January 2019, we entered into an amendment to the Merck CodeEvolver® Agreement whereby we installed certain 
CodeEvolver® protein engineering technology upgrades into Merck’s platform license installation. We maintained those 
upgrades for a multi-year term that expired in January 2022. 

Novartis 

In May 2019, we entered into a Platform Technology Transfer and License Agreement (the “Novartis CodeEvolver® 

Agreement”) with Novartis. The Novartis CodeEvolver® Agreement allows Novartis to use our proprietary CodeEvolver® 
protein engineering platform technology in the field of human healthcare.  

Under the terms of the Novartis CodeEvolver® Agreement, Codexis granted to Novartis a worldwide license to use certain 

patents, patent applications and know-how from our CodeEvolver® protein engineering technology platform to research, 
develop and manufacture novel enzymes for use by or on behalf of Novartis as biocatalysts in the chemical synthesis of small 
molecule and bioconjugate active pharmaceutical ingredients (“API”). The license is exclusive for the research, development 

9 

 
and manufacture of novel enzymes for use by Novartis as biocatalysts in the chemical synthesis of API owned or controlled by 
Novartis (“Novartis Exclusive Field”) and non-exclusive license for the research, development and manufacture of novel 
enzymes for use by Novartis in the chemical synthesis of API not owned or controlled by Novartis or any third party (“Novartis 
Non-Exclusive Field”). 

In July 2021, we announced the completion of the technology transfer period during which we transferred our proprietary 

CodeEvolver® platform technology to Novartis (the “Technology Transfer Period”). 

Pursuant to the Novartis CodeEvolver® Agreement, we received an upfront payment of $5.0 million shortly after the 
effective date. We completed the second technology milestone transfer under the agreement and received a milestone payment 
of $4.0 million in 2020. We have also received an aggregate of $5.0 million for the completion of the third technology transfer 
milestone in 2021.  

In consideration for the continued disclosure and license of improvements to the technology and materials during a multi-

year period that began on the conclusion of the Technology Transfer Period (“Improvements Term”), Novartis will pay us 
annual payments over four years which amount to an additional $8.0 million in aggregate. We also have the potential to receive 
quantity-dependent, usage payments for each API that is manufactured by Novartis using one or more enzymes that have been 
developed or are in development using the CodeEvolver® platform technology during the period that began on the conclusion 
of the Technology Transfer Period and ends on the expiration date of the last to expire licensed patent. These product-related 
usage payments, if any, will be paid by Novartis to Codexis for each quarter that Novartis manufactures API using a 
CodeEvolver ® -developed enzyme.  

The licenses to Novartis are granted under patents, patent applications and know-how that Codexis owns or controls as of 

the effective date and that cover the CodeEvolver® platform technology. Any improvements to the CodeEvolver® platform 
technology during the Technology Transfer Period will also be included in the license grants from Codexis to Novartis. 

See also "Recent Development - Pfizer (PAXLOVID™)" above for information on our relationship with Pfizer. 

Biotherapeutic Discovery and Development Partnerships 

We are also targeting new opportunities in the pharmaceutical industry to discover or improve biotherapeutic drug 

candidates for our customers. We believe that our CodeEvolver® protein engineering platform technology can be used to 
discover novel biotherapeutic drug candidates that will target human diseases that are in need of improved therapeutic 
interventions. Similarly, we believe that we can deploy our platform technology to improve specific characteristics of a 
customer’s pre-existing biotherapeutic drug candidate, such as its activity, stability or immunogenicity. 

We approach biopharmaceutical companies to collaborate and utilize our platform technology for the discovery of specific 
novel biotherapeutic candidates. We currently have one such biotherapeutic discovery partnership in progress under the Nestlé 
SCA with Nestlé Health Science and another discovery partnership in progress under the Takeda Agreement with Takeda. We 
continue to pursue other partners who could benefit by the application of our CodeEvolver® protein engineering platform 
technology to improve the discovery and/or development of other biotherapeutics in partnership with us. 

Biotherapeutic Product Discovery and Development 

We are also using our platform technology to self-fund the development of our own early stage, novel enzyme therapeutic 
product candidates. The first product candidate that resulted from this is CDX-6114, an enzyme which we have engineered to 
be orally administered and is being developed by Nestlé Health Science as a potential treatment of PKU in humans. PKU is an 
inborn metabolic disorder in which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient. 
As a result, phenylalanine accumulates to toxic levels in the brain, causing serious neurological problems including intellectual 
disability, seizures and cognitive and behavioral problems. To avoid toxic levels of phenylalanine in their blood, individuals 
with PKU must follow a strict, life-long diet that is low in phenylalanine and supplement their diet with a synthetic 
phenylalanine-free formula to provide them with sufficient nutrients. Maintaining a strict, life-long diet can be challenging for 
individuals with PKU. There are an estimated 50,000 people with PKU in the developed world. 

Our self-funded biotherapeutic investments aim to discover therapeutic solutions for five additional rare disease conditions. 

Two of those programs are targeting potential enzyme substitution treatments for patients with inborn errors of amino acid 
metabolism diseases.  

CDX-6512 is an orally administrable enzyme substitution therapy candidate in IND-enabling studies for potential treatment 

of homocystinuria (HCU). The U.S. Food and Drug Administration (FDA) has granted the company orphan drug designation 
(ODD) and rare pediatric disease (RPD) designation for CDX-6512 for the treatment of HCU, an inborn metabolic disorder 
most commonly due to cystathionine beta-synthase (CBS) deficiency. CBS is an enzyme involved in the metabolism of 

10 

 
homocysteine, a methionine metabolite. As a result, methionine and/or homocysteine accumulate to toxic levels, that may lead 
to learning and intellectual disabilities, cardiovascular disease, osteoporosis, and stroke. To prevent blood levels of methionine 
and/or homocysteine to become toxic, individuals with HCU must follow a strict, life-long diet that is low in methionine and 
supplement their diet with a synthetic methionine-free formula to provide them with sufficient nutrients. Maintaining a strict, 
life-long diet can be challenging for individuals with HCU. World-wide about 1 in 150,000 people has HCU due to either a 
CBS or an MTHFR gene mutation. HCU is listed on the Recommended Uniform Screening Panel of disorders recommended by 
the Secretary of the Department of Health and Human Services for states to screen as part of their universal newborn screening 
programs. 

CDX-6210 is an orally administrable enzyme substitution therapy lead for potential treatment of Maple Syrup Urine 
Disease (MSUD). MSUD is an inborn metabolic disorder in which the branched-chain keto acid dehydrogenase enzyme that is 
involved in the metabolism of branched-chain amino acids such as leucine, isoleucine, and valine, is deficient. As a result, these 
amino acids and their ketoacid metabolites accumulate to toxic levels, that can lead to intellectual and developmental 
disabilities. To prevent blood levels of these amino acids and their metabolites to become toxic, individuals with MSUD must 
follow a strict, life-long diet that is low in branched-chain amino acids and supplement their diet with a synthetic branched-
chain amino acids-free formula to provide them with sufficient nutrients. Maintaining a strict, life-long diet can be challenging 
for individuals with MSUD. According to the Genetic and Rare Disease Information Center (GARD), about 1 in 150,000-
185,000 people is born with MSUD. MSUD is listed on the Recommended Uniform Screening Panel of disorders 
recommended by the Secretary of the Department of Health and Human Services for states to screen as part of their universal 
newborn screening programs. 

Our discovery program target a potential enzyme therapy for gluten management and potential treatments for patients with 

lysosomal storage diseases, via a specific novel transgene, or via a new AAV technology. We expect to continue to make 
additional investments with the aim of generating additional product candidates targeting these, and potentially other 
therapeutic areas. 

Nestlé Health Science 

In October 2017, we entered into the Nestlé License Agreement with Nestlé Health Science pursuant to which we granted 

to Nestlé Health Science, under certain of our patent rights and know-how: (i) an option to obtain an exclusive, worldwide, 
royalty-bearing, sublicensable license to develop and commercialize certain products (each, a “Product”) based on CDX-6114 
and our other therapeutic enzyme product candidates covered by specified patent applications for the treatment of HPA (also 
referred to as PKU), and (ii) an exclusive right of first negotiation (the “Right of First Negotiation”) for a period of five years to 
obtain an exclusive worldwide license to develop and commercialize up to two enzymes discovered by us for use in the field of 
the prevention, diagnosis, treatment and management of inborn errors of amino acid metabolism. We are not under any 
obligation to undertake any research and development activities relating to inborn errors of amino acid metabolism. HPA is a 
medical condition characterized by elevated concentrations of the amino acid phenylalanine in the blood. PKU can result in 
severe HPA.  

In February 2019, Nestlé Health Science exercised its option to obtain an exclusive, worldwide, royalty-bearing, sub-

licensable license for the global development and commercialization of CDX-6114 for the management of PKU. 

Upon exercising its option, Nestlé Health Science assumed all responsibilities for future clinical development and 
commercialization of CDX-6114, with the exception of the completion of an extension study, CDX-6114-004, which was 
substantially completed in the fourth quarter of 2019. The parties established a patent committee to discuss strategies and 
coordinate activities for the patents related to CDX-6114 and product containing CDX-6114, and we will jointly own all 
inventions and information that result from each party’s activities performed under the Nestlé License Agreement. The Nestlé 
License Agreement also contains customary representations and warranties by the parties, intellectual property protection 
provisions, certain indemnification rights in favor of each party and customary confidentiality provisions and limitations of 
liability. 

We are also eligible to receive payments from Nestlé Health Science under the Nestlé License Agreement that include (i) 

development and approval milestones of up to $85.0 million, (ii) sales-based milestones of up to $250.0 million in the 
aggregate, which aggregate amount is achievable if net sales exceed $1.0 billion in a single year, and (iii) tiered royalties, at 
percentages ranging from the mid-single digits to low double-digits, of net sales of products. 

In October 2017, we entered into the Nestlé SCA pursuant to which we and Nestlé Health Science are collaborating to 
leverage the CodeEvolver® protein engineering technology platform to develop novel enzymes for Nestlé Health Science’s 
established Consumer Care and Medical Nutrition business areas. The term of the Nestlé SCA has been extended through 
December 2022.  

11 

 
In January 2020, we entered into a development agreement with Nestlé Health Science pursuant to which we and Nestlé 

Health Science are collaborating to advance CDX-7108 into preclinical and early clinical studies. CDX-7108 is the lead 
candidate targeting exocrine pancreatic insufficiency discovered under the Nestlé SCA. During 2021, we, together with  Nestlé 
Health Science, continued to advance CDX-7108 towards initiation of a Phase 1 clinical trial with the first subject being dosed 
in November 2021. Additionally, the parties are progressing one orally administered enzyme therapy program under the Nestlé 
SCA targeting a gastrointestinal disorder. 

Shire Human Genetic Therapies/Takeda Pharmaceutical 

In March 2020, we entered into the Takeda Agreement with Takeda pursuant to which we are collaborating to research and 

develop protein sequences for use in gene therapy products for certain diseases (each, a “Field”) in accordance with each 
applicable program plan (each, a “Program Plan”). On execution of the Takeda Agreement, we received an upfront 
nonrefundable cash payment of $8.5 million and we initiated activities under three Program Plans for Fabry Disease, Pompe 
Disease, and an undisclosed blood factor deficiency, respectively (the “Initial Programs”). We are primarily responsible for the 
research and development of protein sequences under the Program Plans (the “Protein Sequences”) and we are eligible to earn 
up to $10.5 million of research and development fees and preclinical milestone payments for the Initial Programs. Takeda has 
the right, but not the obligation, to develop, manufacture and commercialize gene therapy products that include nucleic acid 
sequences that encode the protein sequences (“products”) at their expense. Takeda has the right to a certain number of 
additional disease indications (“Reserved Target Indications”) for a limited time period during which Takeda may initiate a 
Program Plan for one or more Reserved Target Indications (“Additional/Option Program,” with Initial Programs, the 
“Programs”), provided, (a) if Takeda elects to initiate an Additional/Option Program while the parties are collaborating on three 
other Programs at the time of such election, or (b) if Takeda elects to initiate an Additional/Option Program using the last 
remaining Reserved Target Indication, then Takeda must pay us an option exercise fee to initiate such Additional/Option 
Program. We will own all rights to the protein sequences and corresponding nucleic acid sequences and related intellectual 
property rights and Takeda will own all rights to products and related intellectual property rights. In May 2021, Takeda elected 
to exercise their option to initiate an additional program for a certain undisclosed rare genetic disorder; as a result we received 
the option exercise fee during the third quarter of 2021. We are also eligible to receive up to $8.3 million of research and 
development fees and preclinical milestone payments for the fourth program under the Takeda Agreement. 

We granted to Takeda an exclusive, worldwide, royalty-bearing, sublicensable license to use the protein sequences and

Fine Chemicals and Industrial Enzyme Markets 

Beyond the pharmaceutical industry, our CodeEvolver® protein engineering platform technology has enabled cost-savings 

for our partners in the fine chemicals markets, and the food industry in particular. In November 2016, we entered into an 
exclusive agreement with Tate & Lyle, a market-leading food ingredients company, to supply a proprietary enzyme for use in 
Tate & Lyle’s food ingredient production. In March 2017, we entered into a multi-year research and development agreement 
with Tate & Lyle for the development of a second ingredient for the food ingredient industry. We engineered a suite of enzymes 
that enable Tate & Lyle’s novel bioconversion route for the manufacture of their newly-launched zero-calorie TASTEVA® M 
Stevia sweetener.  In July 2021, we entered into a multi-year supply agreement with Kalsec to supply an enzyme product for 

12 

 
use in the production of Kalsec's newest natural hop acid.  

We are seeking to expand our enzyme offerings in the fine chemical and industrial enzyme markets within and beyond the 
food industry, including, for example, to the animal feed, agricultural chemicals, consumer care, flavors and fragrances markets.  

Molecular Biology and In Vitro Diagnostic Enzymes  

We believe that our protein engineering capability can also be deployed to commercialize novel enzymes as improvements 
to enzymes consumed by customers in many industrial sectors. As our first effort in this strategy, we have developed enzymes 
for customers using NGS and PCR/qPCR for in vitro molecular diagnostic applications. In December 2019, we entered into a 
license agreement to provide Roche with our EvoT4™ DNA ligase high-performance molecular diagnostic enzyme. This 
enzyme was developed using our proprietary CodeEvolver® protein engineering platform and is expected to be incorporated 
into Roche’s NGS library preparation kits and other sequencing products. During 2021, we commercialized three additional 
enzymes, our Codex® HiFi DNA Polymerase for use in next generation sequencing, our Codex® HiTemp Reverse Transcriptase 
for use in molecular diagnostic applications, and our Codex® HiCap RNA Polymerase for use in RNA synthesis applications. 

Biocatalyst Products and Services 

Our biocatalyst products and services can deliver value to our customers in multiple potential ways: 

• 

• 

• 

• 

• 

• 

manufacture their products at lower cost; 

manufacture their products with lower fixed capital investment; 

reduce the cost of development of complex chemical synthesis processes; 

enable their products to achieve higher product purity; 

allow the removal of entire steps from chemical production; and 

provide flexibility to apply at any point across their product’s lifecycle. 

Our products include biocatalysts, chemical intermediates and Codex® biocatalyst panels and kits. We sell our products 

worldwide primarily through our direct sales and business development force in the United States and Europe. 

In addition to products, we also offer research and development services to our customers. These research and development 

service agreements often contain service fee payments and intellectual property provisions under which we screen and/or 
engineer biocatalysts for customers in connection with their process development efforts. In these collaborations, we typically 
receive consideration in the form of one or more of the following: upfront payments, milestone payments, payments for 
screening and engineering services, licensing fees and royalties. 

Biocatalysts 

We often sell biocatalysts, by the gram or kilogram, that have already been engineered, scaled up, and installed in a 
customer’s commercial process. For example, we sell biocatalysts to Merck for their manufacture of Sitagliptin, the active 
ingredient in Januvia®. We also sell biocatalysts which are in developmental stages. These are enzymes that are sold by the 
batch or by the gram or kilogram that are in the process of being engineered or scaled up by Codexis, or are in the process of 
being trialed or approved for use in the customer’s process. We may sell batches of specific biocatalysts that are in the midst of 
protein engineering efforts, in order to test their performance at a larger scale or to accelerate a customer’s process 
development. We may also sell batches of specific biocatalysts for use in a customer’s developmental products (for example, 
for use in the manufacture of a customer’s Phase 2 drug candidate). Finally, we may sell batches of specific biocatalysts as a 
customer performs trials for approval in their commercial manufacturing operations. 

Chemical Intermediates 

In some cases, we sell intermediate chemicals products that are produced in a process that uses our biocatalysts. These 

chemical intermediates are then used by our customer for further chemical processing.  

Codex® Biocatalyst Panels and Kits 

We sell kits and panels of our biocatalysts. These kits and panels assemble a relevant subset of our engineered enzymes to 

enable customers to perform chemistry screening on their own. These kits and panels are organized by specific types of 
chemical reactions that are widely applicable in the pharmaceutical and fine chemical markets. 

13 

 
Biocatalyst Screening Services 

If a customer prefers, rather than purchasing our Codex® Biocatalyst Panels or Kits to use for its own screening, it may 

send us its starting materials and desired chemical reaction, and we will test against our existing libraries of enzymes on a 
research and development service fee basis. If we detect desired activity in a specific enzyme, we can supply the customer with 
this enzyme or perform engineering services to improve the performance of the enzyme. 

Protein Engineering Services 

We work with our customers throughout their product development lifecycle to optimize enzymes that have been 

engineered specifically to perform a desired process according to a highly selective set of specifications. We typically charge 
customers for research and development services by project or project-month. These are typically larger research and 
development service fees than screening services. 

The protein engineering process starts by identifying genes that code for enzymes known to have the general type of 

catalytic reactivity for a desired chemical reaction. Typically, we identify gene sequences from our extensive in-house 
collection or from published databases and then synthesize candidate genes having those sequences. Using a variety of 
biotechnology tools, we diversify these genes by introducing mutations, giving rise to changes in the enzymes for which they 
encode. The methods for diversifying these genes, and types of diversity being tested, often vary over the course of a protein 
engineering program. For finding initial diversity, methods typically include random mutagenesis and site-directed (included 
computational structure-guided) mutagenesis. We also test mutational variations from related enzymes found in different 
organisms. 

Once we have identified potentially beneficial mutations, we create libraries of thousands of variants with combinations of 

these mutations. With our proprietary genetic manipulation tools, we generate libraries of genes that have programmed and 
random combinations of mutations for testing. The pool of genes is used to transform host cells, which entails introducing the 
various genes into host cells. These cells are then grown into colonies. Cells from individual colonies are cultured in high 
throughput to produce the enzyme encoded by the genetic variant in those cells. The enzymes expressed by these cells are then 
screened in high throughput using test conditions relevant to the desired application. The screening results allow us to identify 
and catalog individual genes that produce improved enzymes with beneficial mutations as well as enzymes having detrimental 
ones. Using specifically developed test conditions and analytical methods, we can identify variant enzymes that exhibit various 
improved performance characteristics, such as stability, activity and selectivity, under conditions relevant to the desired 
chemical process. 

In the next step in our optimization process, we use our proprietary bioinformatics software to analyze protein sequence-

activity relationships. Our software and algorithms relate the screening results to the mutations and rank the individual and 
interacting protein sequence mutations with regard to their degree of benefit or detriment, relative to the process parameter(s) 
tested. Using this information, we can create a select pool of mutational diversity in the next iteration to further the 
accumulation of beneficial diversity and cancel out detrimental diversity in the individual genes in the resulting library. The 
gene that codes for the best performing enzyme in one iteration is used as the starting gene for the next iteration of 
recombination and screening. As the enzymes improve over these iterations, the screening conditions are made increasingly 
more stringent. In this way, the biocatalyst is rapidly optimized until all in-process performance requirements have been 
achieved and the economic objectives for the desired process have been met.

INTELLECTUAL PROPERTY 

Our success depends in large part on our ability to protect our proprietary products and technology under patent, copyright, 

trademark and trade secret laws. We also rely heavily on confidential disclosure agreements for further protection of our 
proprietary products and technologies. Protection of our technologies is important for us to offer our customers and partners 
proprietary services and products that are not available from our competitors, and to exclude our competitors from practicing 
technology that we have developed or exclusively licensed from other parties. For example, our ability to supply innovator 
pharmaceutical manufacturers depends on our ability to supply proprietary enzymes or methods for making pharmaceutical 
intermediates or APIs that are not available from our competitors. Likewise, in the generic pharmaceutical area, proprietary 
protection, through patent, trade secret or other protection of our enzymes and methods of producing a pharmaceutical product 
is important for us and our customers to maintain a lower cost production advantage over competitors.  

As of December 31, 2021, we owned or controlled approximately 1,900 issued patents and pending patent applications in 

the United States and in various foreign jurisdictions, many of which are directed to our enabling technologies and specific 
methods and products that support our business in the pharmaceutical markets. In addition, our portfolio includes patents and 
pending patent applications that support our businesses in the biotherapeutics, molecular diagnostics, food and other markets. 
Our patents and pending patent applications, if issued, have terms that expire between 2022 and approximately 2042. Our 
United States ("U.S.") patents and pending patent applications directed to the CodeEvolver® proprietary enabling technology 
platform developed internally by us have terms that expire between 2029 and approximately 2034. It is possible that some U.S. 
patents may be entitled to patent term extensions and/or patent term adjustments, which would extend the protection beyond 
these expiration dates. It is also possible that some patents in other jurisdictions will be entitled to additional patent term. Our 
current intellectual property rights also include patents, trademarks, copyrights, software and certain assumed contracts that we 
acquired from Maxygen, Inc. (“Maxygen”) in October 2010, which are associated with directed evolution technology, known as 
the MolecularBreeding™ technology platform developed by Maxygen. The intellectual property rights and assets that we 
acquired from Maxygen continue to be subject to existing exclusive and non-exclusive license rights granted by Maxygen to 
third parties. We continue to file new patent applications, for which terms generally extend 20 years from the non-provisional 
filing date in the United States.  

As of December 31, 2021, we owned 100 trademark registrations in the United States and foreign jurisdictions, as well as 

many common law trademarks. These include, but are not limited to: Codexis®, Codex®, CodeEvolver®, Mosaic®, Sage®, 
Microcyp®, MCYP®, ProSAR®, Unlock the Power of Proteins®, the Codexis Protein Engineering Experts® logo, Strategist™, 
Continuity®™, Ameli™, Forager®™, Analogene®™, Harvester®™, Atoms®™, Riptide®™, APS™ and a Codexis design mark 
(i.e., the stylized Codexis logo). 

COMPETITION 

We face differing forms of competition in the small molecule pharmaceuticals, biotherapeutics and fine chemicals markets, 

as set forth below. 

Small Molecule Pharmaceuticals 

We market our biocatalyst products and services to manufacturers of small molecule pharmaceutical intermediates and 

APIs. Our primary competitors in that market are companies marketing either conventional, non-enzymatic catalysts or 
alternative biocatalyst products and services. We also sometimes face competition from existing in-house technologies (both 
biocatalysts and conventional catalysts) within our client and potential client companies. The principal methods of competition 
and competitive differentiation in this market are price, product quality and performance, including manufacturing yield, safety 
and environmental benefits and speed of delivery of product. Pharmaceutical manufacturers that use biocatalytic processes can 
face increased competition from manufacturers that use more conventional processes and/or manufacturers that are based in 
regions (such as India and China) with lower regulatory, safety and environmental costs. 

The market for the manufacture and supply of APIs and intermediates is large, with many established companies. These 
companies include many of our large innovator and generic pharmaceutical customers, such as Merck, GSK, Novartis, Pfizer 
Inc. ("Pfizer"), Bristol-Myers Squibb Company ("Bristol-Myers"), KYORIN Pharmaceutical Co., Ltd. ("Kyorin"), Urovant 
Sciences GmbH ("Urovant"), and Teva Pharmaceutical Industries Limited ("Teva"), which have significant internal research 
and development efforts directed at developing processes to manufacture APIs and intermediates. The processes used by these 
companies include classical conventional organic chemistry reactions, chemo-catalytic reactions, biocatalytic reactions or 
combinations thereof. Our biocatalyst based manufacturing processes must compete with these internally developed routes.  

We also compete with companies developing and marketing conventional catalysts include Solvias AG, BASF, Johnson-

Matthey and Takasago International Corporation. 

15 

 
The market for supplying enzymes for use in pharmaceutical manufacturing is quite fragmented. There is competition from 
large industrial enzyme companies, such as Novozymes and Dupont, as well as subsidiaries of larger contract research/contract 
manufacturing organizations (“CRO/CMO”), such as Royal DSM N.V. (“DSM”), Cambrex Corporation, Lonza, WuXi STA and 
Almac Group Ltd. Some fermentation pathway design companies, like Ginkgo Bioworks and Zymergen, whose traditional 
focus has been to design microorganisms that express small molecule chemicals, could extend into designing organisms that 
express enzymes. There is also competition in the enzyme customization and optimization area from several smaller companies, 
such as BRAIN AG, Arzeda, c-LEcta GmbH and Evocatal GmbH. 

We believe that our principal advantage is our ability to rapidly deliver customized biocatalysts for existing and new 
intermediates and APIs in the pharmaceutical manufacturing market. This capability has allowed us to create a breadth of 
biocatalysts with improved performance characteristics including, for example, better activity, stability, and activity on a range 
of substrates, compared to traditional chemistry-based manufacturing processes and naturally occurring (and thus not 
optimized) biocatalysts. We believe that our CodeEvolver® protein engineering platform technology provides substantially 
superior results, in shorter time frames, than companies offering competing biocatalyst development services.  

Biotherapeutics 

There are other companies that participate in the biotherapeutics market generally and the PKU market specifically. Many 
of these companies are large, successful and well-capitalized. BioMarin Pharmaceutical Inc. (“BioMarin”) and Daiichi Sankyo 
Company market Kuvan® in the United States, Europe and Japan for the treatment of a certain type of PKU. In addition, 
BioMarin had gained FDA approval in May 2018 and began the commercial sales of Palynziq®, an injectable enzyme 
substitution therapy to address different options for care in the treatment of PKU. Subsequently in May 2019, BioMarin 
obtained marketing authorization for Palynziq® from the European Commission. Several companies, including Synlogic, 
Homology Medicines and Rubius have reported clinical efforts to develop biotherapeutic candidates for PKU. Beyond targeting 
PKU, Takeda, Genzyme / Sanofi S.A., BioMarin, and other companies market or are actively developing enzyme therapeutics. 
There are numerous companies that are developing other forms of therapeutics, such as small molecules, gene therapy, as well 
as therapies based on gene editing, which could compete with biotherapeutics. 

Fine Chemicals 

We face similar forms of competition in this market as in the small molecule pharmaceutical markets, with the exception 

that the risk of losing opportunities to larger competitors in fine chemicals is greater given the larger scale of opportunities 
available in the fine chemicals market compared to the pharmaceutical market. Our significant competitors in the fine 
chemicals markets include companies that have been in these marketplaces for many years, such as DuPont Industrial 
Biosciences ("DuPont Genencor"), DSM, Novozymes and A.B. Enzymes. These companies have greater resources in these 
markets than we do and have long-term supply arrangements already in place with customers. Our ability to compete in these 
markets may be limited by our relatively late entrance. We also face competition in both the fine chemicals and small molecule 
pharmaceutical markets from emerging companies, like Zymergen and Gingko Bioworks, who offer engineered microbe 
metabolic pathway approaches to these markets. 

Core Technology 

We are a leader in the field of protein engineering to create novel biocatalysts. Both our pharmaceuticals and fine 
chemicals businesses rely on our core technology. We are aware that other companies, organizations and persons have 
developed technologies that appear to have some similarities to our patented proprietary technologies. For example, we are 
aware that other companies, including Zymergen, Gingko Bioworks, Amyris, Absci and Amicus Therapeutics have alternative 
methods for obtaining and generating genetic diversity or use mutagenesis techniques to produce genetic diversity. In addition, 
academic institutions such as the California Institute of Technology, the Max Planck Institute and the Austrian Centre of 
Industrial Biotechnology are also working in this field. This field is highly competitive with companies and academic and 
research institutions actively seeking to develop technologies that could be competitive with our technologies. 

Technological developments by others may result in our products and technologies, as well as products manufactured by 

our customers using our biocatalysts, becoming obsolete. We monitor publications and patents that relate to directed molecular 
evolution to be aware of developments in the field and evaluate appropriate courses of action in relation to these developments.  

Many of our competitors have substantially greater manufacturing, financial, research and development, personnel and 

marketing resources than we do. As a result, our competitors may be able to develop competing and/or superior technologies 
and processes, and compete more aggressively and sustain that competition over a longer period of time than we could. Our 
technologies and products may be rendered obsolete or uneconomical by technological advances or entirely different 
approaches developed by one or more of our competitors.

OPERATIONS 

Our corporate headquarters are located in Redwood City, California and provide general administrative support to our 
business and are the center of our research, development and business operations. We have limited internal manufacturing 
capacity at our headquarters in Redwood City. We expect to rely on third-party manufacturers for commercial production of our 
biocatalysts for the foreseeable future. Our in-house manufacturing is dedicated to producing both Codex® biocatalyst panels 
and kits and enzymes for use by our customers in pilot scale production. We also supply initial commercial quantities of 
biocatalysts for use by our collaborators to produce pharmaceutical intermediates and manufacture biocatalysts that we sell. In 
the first quarter of 2021, we entered into an arrangement to lease a facility in San Carlos, California to serve as an additional 
office and research and development laboratory space which we occupied beginning December 2021. Please see Note 15, 
“Segment, Geographical and Other Revenue Information” in the Notes to the Consolidated Financial Statements set forth in 
Item 8 of this Annual Report on Form 10-K for a description of our revenues and long-lived assets both within and outside of 
the United States, and with respect to the San Carlos facility, please see Note 13, “Commitments and Contingencies” in the 
Notes to our Consolidated Financial Statements set forth in Item 8 of this Annual Report on Form 10-K. 

Our research and development operations include efforts directed towards engineering biocatalysts, bioprocess 
development, cellular engineering, biocatalyst screening, metabolites, strain improvement, fermentation development and 
process engineering. We conduct enzyme evolution, enzyme production development, microbial bioprocess development, 
cellular engineering, microbial evolution and process engineering evaluations and design primarily at our headquarters in 
Redwood City, California. Manufacturing of our enzymes is conducted primarily in four locations, at our in-house facility in 
Redwood City, California and at third-party contract manufacturing organizations, Lactosan GmbH & Co. KG (“Lactosan”) in 
Kapfenberg, Austria, ACS Dobfar S.p.A. ("ACSD") (formerly know as DPhar S.p.A.) in Anagni, Italy, and Alphazyme LLC 
("Alphazyme") in Florida, United States. Generally, we perform smaller scale manufacturing in-house and outsource the larger 
scale manufacturing and a large percentage of our production of novel enzymes to contract manufacturing organizations. 

GOVERNMENT REGULATION 

In the United States, the FDA extensively regulates, among other things, the research, development, testing, manufacture, 

quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, 
advertising, promotion, marketing, post-approval monitoring, and post-approval reporting of drug and biologic products under 
the Federal Food, Drug and Cosmetic Act, its implementing regulations and other laws, including, in the case of biologics, the 
Public Health Service Act. Our biotherapeutic product candidates are subject to regulation by the FDA as biologics. Biologics 
require the submission of a biologics license application (“BLA”) and licensure, which constitutes approval, by the FDA before 
being marketed in the United States. We, along with third-party contractors and our collaborators, will be required to navigate 
the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in 
which we wish to conduct studies or seek approval or licensure of our product candidates. The process of obtaining regulatory 
approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations require the 
expenditure of substantial time and financial resources. 

The process required by the FDA before a biologic product may be marketed in the United States generally involves the 

following: 

completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s good laboratory 

• 
practice (“GLP”) regulations; 

• 

submission to the FDA of an IND, which must become effective before clinical trials in the United States may begin; 

approval by an institutional review board (“IRB”), or ethics committee at each clinical site before the trial is 

• 
commenced; 

• 
performance of adequate and well-controlled human clinical trials to establish the safety, purity, and potency of the 
product candidate for each proposed indication, conducted in accordance with the FDA’s good clinical practice (“GCP”) 
regulations; 

• 

• 

• 

preparation and submission to the FDA of a BLA after completion of all pivotal clinical trials: 

satisfactory completion of an FDA Advisory Committee review, if applicable; 

a determination by the FDA within 60 days of its receipt of a BLA to file the application for review; 

• 
satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is 
produced to assess compliance with current good manufacturing practice (“cGMP”) regulations and to assure that the 
facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency, and 
of selected clinical investigation sites to assess compliance with Good Clinical Practices, or GCPs; and 

17 

 
• 

FDA review and approval of the BLA prior to any commercial marketing, sale or distribution of the product. 

Preclinical and Clinical Trials 

Once a product candidate is identified for development, it enters the preclinical testing stage. Preclinical studies include 
laboratory evaluations of drug chemistry, formulation and stability, as well as studies to evaluate toxicity in animals, which 
must be conducted in accordance with GLP requirements. The results of preclinical studies, together with manufacturing 
information and analytical data, are submitted to the FDA as part of an IND. An IND is a request for authorization from the 
FDA to administer an investigational new drug to humans. The central focus of an IND submission is on the general 
investigational plan and the protocol(s) for clinical studies. The IND automatically becomes effective 30 days after receipt by 
the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial, 
including concerns that human research subjects will be exposed to unreasonable health risks, and imposes a clinical hold. In 
such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin.  

A separate submission to an existing IND must also be made for each successive clinical trial conducted during product 
development, and the FDA must grant permission, either explicitly or implicitly by not objecting, before each clinical trial can 
begin. Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually 
to the FDA and written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected 
suspected adverse events, findings from other studies or animal or in vitro testing that suggest a significant risk for human 
subjects and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol 
or investigator brochure. 

Clinical trials involve the administration of the product candidate to human subjects under the supervision of qualified 
investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent 
for their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things, the 
objectives of the clinical trial and the parameters and criteria to be used in monitoring safety and evaluating effectiveness. Each 
protocol must be submitted to the FDA as part of the IND. An independent IRB for each investigator site proposing to 
participate in a clinical trial must also review and approve the clinical trial and its informed consent form before it can begin at 
that site, and the IRB must monitor the clinical trial until it is completed. The FDA, the IRB, or the sponsor may suspend or 
discontinue a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an 
unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an 
independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which 
provides authorization for whether or not a study may move forward at designated check points based on access to certain data 
from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other 
grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies 
and clinical study results to public registries. 

For purposes of BLA approval, clinical trials are typically conducted in three sequential phases, which may overlap or be 

combined. 

•  Phase 1 - Phase 1 clinical trials involve initial introduction of the investigational product into healthy human subjects 
or patients with the target disease or condition. These studies are typically designed to test the safety, dosage tolerance, 
absorption, metabolism and distribution of the investigational product in humans, the side effects associated with 
increasing doses, and, if possible, to gain early evidence of effectiveness. 

•  Phase 2 - Phase 2 clinical trials typically involve administration of the investigational product to a limited patient 
population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosage and dosing schedule 
and to identify possible adverse side effects and safety risks. 

•  Phase 3 - Phase 3 clinical trials typically involve administration of the investigational product to an expanded patient 
population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for 
safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the 
overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval and physician 
labeling. 

In some cases, the FDA may condition approval of a BLA on the sponsor’s agreement to conduct additional clinical trials 

to further assess the biologic’s safety and effectiveness after BLA approval. Such post-approval clinical trials are typically 
referred to as Phase 4 clinical trials. Concurrent with clinical trials, companies usually complete additional animal studies and 
must also develop additional information about the chemistry and physical characteristics of the biologic and finalize a process 
for manufacturing the biologic in commercial quantities in accordance with cGMP requirements. The manufacturing process 
must be capable of consistently producing quality batches of the product candidate and manufacturers must develop, among 
other things, methods for testing the identity, strength, quality and purity of the final biological product. Additionally, 

18 

 
appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product 
candidate does not undergo unacceptable deterioration over its shelf life. 

Although most clinical research performed in the United States in support of a BLA must be authorized in advance by the 

FDA, under the IND regulations and procedures described above, there are certain circumstances under which clinical trials can 
be conducted without submission of an IND. For example, a sponsor who wishes to conduct a clinical trial outside the United 
States may, but need not, obtain FDA authorization to conduct the clinical trial under an IND. 

BLA Submission and FDA Review 

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the 
results of preclinical studies and clinical trials, together with other detailed information, including extensive manufacturing 
information and information on the composition of the biologic, are submitted to the FDA in the form of a BLA requesting 
approval to market the biologic for one or more specified indications. The BLA must include all relevant data available from 
preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed 
information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. Data can 
come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of the product, or from a 
number of alternative sources, including studies initiated by investigators. The submission of a BLA requires payment of a 
substantial user fee unless a waiver is granted. Each BLA submitted to the FDA is reviewed for administrative completeness 
and reviewability within 60 days of the FDA’s receipt of the application. If the BLA is found to be complete, the FDA will file 
the BLA, triggering a full substantive review of the application. The FDA may refuse to file any BLA that it deems incomplete 
or not properly reviewable at the time of submission. 

Once a BLA has been accepted for filing under the Prescription Drug User Fee Act, the FDA has a goal of reviewing BLAs 

within ten months of the 60-day filing date for BLAs designated for standard review or six months for priority review, but the 
overall timeframe is often extended by FDA requests for additional information or clarification. The FDA reviews a BLA to 
determine, among other things, whether the biological product is safe, pure and potent and whether the facility or facilities in 
which it is manufactured meet standards designed to assure the product’s continued safety, purity and potency. The FDA may 
refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should 
be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such 
recommendations. 

Before approving a BLA, the FDA will inspect the facility or the facilities at which the biologic product is manufactured, 

and will not license the product unless cGMP compliance is satisfactory. The FDA may also inspect the sites at which the 
clinical trials were conducted to assess their compliance with GCP requirements, and will not license the biologic unless 
compliance with such requirements is satisfactory. If the FDA determines that the application, manufacturing process or 
manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional 
testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide 
that the application does not satisfy the regulatory criteria for approval. 

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product 
and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response Letter (“CRL”). An 
approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A 
CRL will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the 
data supporting the application are inadequate to support approval, the FDA may issue the CRL without first conducting 
required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the CRL, the FDA may 
recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional 
information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, 
require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of 
a product. 

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail 
limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a 
Risk Evaluation and Mitigation Strategy (“REMS”), to ensure the benefits of the product outweigh its risks. A REMS is a safety 
strategy implemented to manage a known or potential serious risk associated with a product and to enable patients to have 
continued access to such medicines by managing their safe use, and could include medication guides, physician communication 
plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. 
The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate 
controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-
marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require 
one or more Phase 4 post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness 
after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

Expedited Development and Review Programs 

The FDA maintains several programs intended to facilitate and expedite development and review of new drugs and 

biologics to address unmet medical needs in the treatment of serious or life-threatening diseases or conditions.  

For example a product candidate is eligible for Fast Track designation if it is intended to treat a serious or life-threatening 

disease or condition and demonstrates the potential to address unmet medical needs for such disease or condition. Fast Track 
designation applies to the combination of the product candidate and the specific indication for which it is being studied. Fast 
Track designation provides increased opportunities for sponsor meetings with the FDA during preclinical and clinical 
development, in addition to the potential for rolling review once a marketing application is filed, meaning that the FDA may 
review portions of the marketing application before the sponsor submits the complete application, if the sponsor provides a 
schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and determines that the 
schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.,  

In addition, a product candidate may be eligible for Breakthrough Therapy designation if it is intended to treat a serious or 

life-threatening disease or condition and preliminary clinical evidence indicates that the product candidate may demonstrate 
substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment 
effects observed early in clinical development. Breakthrough Therapy designation provides all the features of Fast Track 
designation in addition to intensive guidance on an efficient development program beginning as early as Phase 1, and FDA 
organizational commitment to expedited development, including involvement of senior managers and experienced review staff 
in a cross-disciplinary review, where appropriate. 

Any product candidate submitted to the FDA for approval, including a product candidate with Fast Track or Breakthrough 

Therapy designation, may also be eligible for additional FDA programs intended to expedite the review process, including 
Priority Review designation and Accelerated Approval. A BLA is eligible for Priority Review if the product candidate is 
designed to treat a serious or life-threatening disease or condition, and if approved, would provide a significant improvement in 
safety or effectiveness in the treatment, diagnosis or prevention of a serious disease or condition.  

Additionally, product candidates studied for their safety and effectiveness in treating serious or life-threatening diseases or 
conditions may receive Accelerated Approval if they can be shown to have an effect on a surrogate endpoint that is reasonably 
likely to predict clinical benefit, or an effect on a clinical endpoint that can be measured earlier than an effect on irreversible 
morbidity or mortality which is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical 
benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative 
treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-
controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or 
other clinical benefit. Products receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor 
fails to conduct the required post-marketing studies or if such studies fail to verify the predicted clinical benefit. In addition, the 
FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely 
impact the timing of the commercial launch of the product. 

Fast Track designation, Breakthrough Therapy designation, Priority Review designation and Accelerated Approval do not 
change the standards for approval but may expedite the development or review process. Even if a product qualifies for one or 
more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide 
that the time period for FDA review or approval will not be shortened. 

Orphan drug designation and exclusivity 

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or 
condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or 
a patient population greater than 200,000 individuals in the United States and when there is no reasonable expectation that the 
cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United 
States for that drug or biologic. Orphan drug designation must be requested before submitting a BLA. After the FDA grants 
orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the 
FDA. 

If a product candidate that has orphan drug designation subsequently receives the first FDA approval for a particular active 

ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means 
that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication 
for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug 
exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of 
sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was 
designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease 

20 

 
or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug 
designation are tax credits for certain research and a waiver of the BLA application user fee. 

A designated orphan drug many not receive orphan drug exclusivity if it is approved for a use that is broader than the 
indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States 
may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if a second 
applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the 
manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with 
the rare disease or condition.  

Post-Approval Requirements 

Licensed biologics that are manufactured and distributed in the United States are subject to pervasive and continuing 
regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product 
distribution, advertising and promotion and reporting of adverse experiences with the product. There is also a continuing, 
annual prescription drug program user fee. 

Any biologics manufactured or distributed pursuant to FDA approvals remain subject to ongoing regulation by the FDA. 
Manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, 
and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing 
regulatory requirements, including cGMP, which impose extensive procedural and documentation requirements. Failure to 
comply with statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as 
warning letters, suspension of manufacturing, product seizures, injunctions, civil penalties or criminal prosecution. 

Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or 

frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the 
approved labeling to add new safety information, requirements for post-market studies or clinical trials to assess new safety 
risks, imposition of distribution or other restrictions under a REMS. Other potential consequences include, among other things: 

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or 

• 
product recalls; 

• 

fines, warning letters, untitled letters, or holds on post-approval clinical trials; 

refusal of the FDA to approve applications or supplements to approved applications, or suspension or revocation of 

• 
product approvals; 

• 

product seizure or detention, or refusal to permit the import or export of products;  

•  mandated modification of promotional materials and labeling and the issuance of corrective information; 

the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing 

• 
warnings or other safety information about the product; or 

• 

injunctions or the imposition of civil or criminal penalties. 

The FDA closely regulates the post-approval marketing and promotion of biologics, including standards and regulations for 

direct-to-consumer advertising, off-label promotion, industry-sponsored scientific and educational activities, and promotional 
activities involving the internet and social media. A company can make only those claims relating to safety and efficacy that are 
approved by the FDA. Physicians may prescribe legally available biologics for uses that are not described in the product’s 
labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical 
specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. 

 The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose 
stringent restrictions on manufacturers’ communications regarding off-label use. Failure to comply with these requirements can 
result in adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. 

Biosimilars and Regulatory Exclusivity 

As part of the Patient Protection and Affordable Care Act enacted in 2010, as amended by the Health Care and Education 
Reconciliation Act of 2010, the Biologics Price Competition and Innovation Act (“BPCIA”) established an abbreviated pathway 
for the approval of biosimilar and interchangeable biological products. The abbreviated regulatory pathway provides legal 
authority for the FDA to review and approve biosimilar biologics based on their similarity to an existing brand product, referred 
to as a reference product, including the possible designation of a biosimilar as interchangeable with a brand product.  

21 

 
Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the 
reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical 
study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must 
demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for 
products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or 
switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to 
exclusive use of the reference biologic. 

Under the BPCIA, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date 

on which the reference product was first licensed. Moreover, the extent to which a biosimilar, once approved, will be 
substituted for a reference product in a way that is similar to traditional generic substitution for non-biological drug products is 
not yet clear and will depend on a number of marketplace and regulatory factors that are still developing. In addition, the period 
of exclusivity provided by the BPCIA only operates against third parties seeking approval via the abbreviated pathway, but 
would not prevent third parties from pursuing approval via the traditional BLA approval pathway. 

In addition, a biological product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if 
granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end 
of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in 
accordance with an FDA-issued “Written Request” for such a study. The BPCIA is complex and continues to be interpreted and 
implemented by the FDA. 

Other Healthcare Laws  

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and 

by authorities in the states and foreign jurisdictions in which they conduct their business and may constrain the financial 
arrangements and relationships through which we and our partners research, sell, market and distribute any products for which 
we obtain marketing approval. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false 
claims, data privacy and security and transparency laws regarding drug pricing and payments and other transfer of value to 
physicians and other healthcare providers. If their operations are found to be in violation of any of such laws or any other 
governmental regulations that apply, they may be subject to penalties, including, without limitation, administrative, civil and 
criminal penalties, damages, fines, disgorgement, the curtailment or restructuring of operations, integrity oversight and 
reporting obligations, exclusion from participation in federal and state healthcare programs and individual imprisonment. 

Coverage and Reimbursement  

Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as 
federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and 
the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of 
reimbursement to be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing 
reimbursements for medical products, drugs and services. In addition, the U.S. government, state legislatures and foreign 
governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and 
reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment 
measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales 
of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a 
product could reduce physician usage and patient demand for the product and also have a material adverse effect on sales.  

Healthcare Reform  

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education 

Reconciliation Act, each as amended (collectively known as the “ACA”), was enacted, which substantially changed the way 
healthcare is financed by both governmental and private insurers, and significantly affected the pharmaceutical industry. The 
ACA contained a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement 
adjustments and changes to fraud and abuse laws. For example, the ACA:  

increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 

• 
23.1% of the average manufacturer price;  

• 

required collection of rebates for drugs paid by Medicaid managed care organizations;  

required manufacturers to participate in a coverage gap discount program, under which they must agree to offer 70 

• 
percent point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their 
coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; and  

22 

 
imposed a non-deductible annual fee on pharmaceutical manufacturers or importers who sell “branded prescription 

• 
drugs” to specified federal government programs.  

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA. 

On June 17, 2021, the U.S Supreme Court dismissed the most recent judicial challenge to the AC brought by several states 

without specifically ruling on the constitutionality of the ACA.  Thus, the ACA will remain in effect in its current form. 

Other legislative changes have been proposed and adopted since the Affordable Care Act was enacted, including aggregate 

reductions of Medicare payments to providers of 2% per fiscal year, which was temporarily suspended from May 1, 2020 
through March 31, 2022, and reduced payments to several types of Medicare providers. Moreover, there has recently been 
heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has 
resulted in several Congressional inquiries, proposed and enacted legislation and executive orders issued by the President 
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and 
manufacturer patient programs, and reform government program reimbursement methodologies for drug products. Individual 
states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical 
product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and 
marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other 
countries and bulk purchasing. 

Data Privacy and Security Laws 

Numerous state, federal and foreign laws, including consumer protection laws and regulations, govern the collection, 
dissemination, use, access to, confidentiality, and security of personal information, including health-related information. In the 
United States, numerous federal and state laws and regulations, including data breach notification laws, health information 
privacy and security laws, and federal and state consumer protection laws and regulations (e.g., Section 5 of the Federal Trade 
Commission Act) that govern the collection, use, disclosure, and protection of health-related and other personal information 
could apply to our operations or the operations of our partners. In addition, certain state and non-U.S. laws, such as the 
California Consumer Privacy Act ("CCPA"), the California Privacy Rights Act ("CPRA"), and the General data Protection 
Regulation ("GDPR"), govern the privacy and security of personal information, including health-related information in certain 
circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and 
may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, were applicable, can 
result in the imposition of significant civil and /or criminal penalties and private litigation. Privacy and security laws, 
regulations, and other obligations are constantly evolving, may conflict with each other to make compliance efforts more 
challenging, and can result in investigations, proceedings, or actions that lead to significant penalties and restrictions on data 
processing. 

CUSTOMERS 

We rely on a limited number of key customers for the majority of our revenues. Customers that provided 10% or more of 

our total revenues in any of the past three fiscal years consist of the following:

As of December 31, 2021, we had 261 full-time employees and part-time employees worldwide. Of these employees, 159 
were engaged in research and development, 37 were engaged in operations and quality control and 65 were engaged in selling, 
general and administrative activities. None of our employees is represented by a labor union. Supported by our annual 
employee survey, we believe our relationship with our employees to be generally good. Our scientists, bioinformatics experts 
and other professionals work collaboratively as interdisciplinary teams to unlock and advance technological innovation.  

23 

 
  
 
 
Compensation, benefits and development 

Our goal is to attract, motivate and retain talent with a focus on encouraging performance, promoting accountability and 

adhering to our company values. We offer competitive compensation and benefit programs including a company-matched 
401(k) Plan, stock options for eligible employees, health savings and flexible spending accounts, paid time off, education and 
training programs, and employee assistance programs. We believe it is important to help build community and enabling our 
employees actively participate in community service projects and in company-sponsored philanthropic activities. 

Diversity, inclusion and belonging 

We are committed to our continued efforts to increase diversity and foster an inclusive work environment that supports the 

global workforce and the communities we serve. We recruit the best people for the job regardless of gender, ethnicity or other 
protected traits and it is our policy to fully comply with all laws applicable to discrimination in the workplace. Our diversity, 
equity and inclusion principles are also reflected in our employee training and policies. We continue to enhance our diversity, 
equity and inclusion policies which are guided by our executive leadership team. 

Health and safety 

We are committed to maintain a safe and healthy workplace for our employees. Our policies and practices are intended to 

protect our employees and surrounding communities in which we operate. 

In 2020, in response to the COVID-19 pandemic, we implemented safety protocols and new procedures to protect our 
employees. These protocols include complying with social distancing and other health and safety standards as required by state 
and local government agencies, taking into consideration guidelines of the Centers for Disease Control and Prevention and 
other public health authorities. In addition, we modified the way we conduct many aspects of our business including the 
practice of social distancing, wearing face coverings mandated by state and local regulations, and maintaining a quarantine for 
employees determined to be in close contact with a COVID-19 case. For example, we implemented day-time shift hours in our 
R&D and manufacturing at our Redwood City pilot plant to minimize the number of employees in close proximity to each other 
and we have significantly expanded the use of virtual interaction whenever possible in our business. For a detailed discussion of 
the impact of the COVID-19 pandemic on our human capital resources, see “Risk Factors" Item 1A of this Form 10-K. 

We previously launched the Employee-Requested Work from Home Policy in late 2020. This policy establishes the process 

and criteria to enable Redwood City employees to request permission to work from home on a regular basis.

ITEM 1A. RISK FACTORS  

You should carefully consider the risks described below together with the other information set forth in this Annual 
Report on Form 10-K, which could materially affect our business, financial condition or future results. The risks described 
below are not the only risks facing our company. Risks and uncertainties not currently known to us or that we currently 
deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.  

RISK FACTORS SUMMARY 

The following is a summary of the principal factors that cause an investment in the company to be speculative or risky: 

•  A significant portion of revenue growth in 2021 is as a result of the receipt of purchase orders from Pfizer for 
CDX-616. Revenues in 2022 and in future years from our sales of CDX-616 to Pfizer are subject to a number 
of factors which are outside of our control and may not materialize. 

•  We do not have a long term sale and purchase agreement with Pfizer for CDX-616 and we currently expect 

that future orders for quantities of CDX-616 by Pfizer will continue to be based on the needs of Pfizer for 
quantities of CDX-616. 

•  We have a history of net losses and we may not achieve or maintain profitability.  

•  We are dependent on our collaborators, and our failure to successfully manage these relationships could 

prevent us from developing and commercializing many of our products. 

•  We are dependent on a limited number of customers, including Pfizer. 

•  The ongoing COVID-19 pandemic has adversely affected and may continue in the future to, directly or 

indirectly, adversely affect our business, results of operations and financial condition. 

•  Our product supply agreements with customers have finite duration and may not be extended or renewed. 

•  With respect to customers purchasing our products for the manufacture of API, the termination or expiration 
of such patent protection may materially and adversely affect our revenues, financial condition or results of 
operations. 

•  We are dependent on a limited number of contract manufacturers for large scale production of substantially 

all of our enzymes, including CDX-616. 

• 

If we are unable to develop and commercialize new products for the target markets, our business and 
prospects will be harmed.  

•  Our biotherapeutic programs are early stage, highly regulated and expensive. 

• 

If either Nestlé Health Science or Takeda terminate their development programs under their respective license 
agreements with us, any potential revenue from those license agreements will be significantly reduced or non-
existent. 

•  Our efforts to deploy our technology platform in the fine chemicals market may fail. 

•  We may need additional capital in the future in order to expand our business.  

•  We have investments in non-marketable securities, which may subject us to significant impairment charges. 

•  Competitors and potential competitors who have greater resources and experience than we do may develop 

products and technologies that make ours obsolete. 

•  Ethical, legal and social concerns about genetically engineered products and processes could limit or prevent 

the use of our products, processes, and technologies and limit our revenues. 

• 

If we engage in any acquisitions, we will incur a variety of costs and may potentially face numerous risks that 
could adversely affect our business and operations. 

•  We use hazardous materials in our business and we must comply with environmental laws and regulations. 

•  Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to 

certain limitations. 

•  We or our customers may not be able to obtain regulatory approval for the use of our products in food and 

food ingredients, if required. 

•  Our ongoing efforts to deploy our technology in the life science tools market may fail. 

•  The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time 

consuming and inherently unpredictable, and we may be unable to obtain regulatory approval for our product 
candidates. 

25 

 
•  Clinical trials are difficult to design and implement, expensive, time-consuming and involve an uncertain 

outcome. 

•  Results of preclinical studies and early clinical trials of product candidates may not be predictive of results of 

later studies or trials. 

•  Even if we obtain regulatory approval for any products that we develop alone or with collaborators, such 

products will remain subject to ongoing regulatory requirements. 

•  Our business operations and future relationships with investigators, healthcare professionals, consultants, 
third-party payors, patient organizations and customers will be subject to applicable healthcare regulatory 
laws, which could expose us to penalties. 

•  The successful commercialization of product candidates developed by us or our partners will depend in part 

on the extent to which governmental authorities and health insurers establish adequate coverage, 
reimbursement levels and pricing policies. 

•  Compliance with European Union chemical regulations could be costly and adversely affect our business and 

results of operations. 

•  We rely on third parties to conduct our clinical trials and perform some of our research and preclinical studies, 
which if not satisfactorily carried out or fail to meet expected deadlines, may have an adverse effect on our 
business and prospects. 

•  We contract with third parties for the manufacturing and supply of product candidates, which supply may 

become limited or interrupted or may not be of satisfactory quality and quantity. 

•  Our efforts to prosecute and protect our intellectual property may not be successful. 

•  Our ability to compete may decline if we do not adequately protect our proprietary technologies or if we lose 

some of our intellectual property rights. 

•  Third parties may claim that we are infringing their intellectual property rights or other proprietary rights, 

which may subject us to costly and time-consuming litigation. 

•  We may be involved in lawsuits to protect or enforce our intellectual property rights, which could be 

expensive, time-consuming and unsuccessful. 

•  We may not be able to enforce our intellectual property rights throughout the world. 

• 

If our biocatalysts are stolen, misappropriated or reverse engineered, others could use these biocatalysts to 
produce competing products. 

•  We are subject to anti-takeover provisions in our certificate of incorporation and bylaws and under Delaware 

law that could delay or prevent an acquisition of our company. 

•  Our quarterly or annual operating results may fluctuate in the future. 

•  We do not intend to pay cash dividends for the foreseeable future. 

• 

If securities or industry analysts do not publish research or reports about our business, or publish negative 
reports about our business, our stock price and trading volume could decline. 

•  We face risks associated with our international business. 

•  Business interruptions resulting from disasters or other disturbances could delay us in the process of 

developing our products and could disrupt our sales. 

•  Confidentiality agreements with employees and others may not adequately prevent disclosures of trade 

secrets and other proprietary information. 

•  We are dependent on information technology systems, infrastructure and data, and any failure of these 

systems could harm our business. 

•  Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, 
standards and other requirements could adversely affect our business, results of operations, and financial 
condition. 

•  Evolving expectations around ESG matters may expose us to reputational and other risks.

Risks Relating to Our Business and Strategy  

A significant portion of our revenue growth in 2021 is as a result of the receipt of purchase orders from Pfizer for a 

proprietary enzyme product ("CDX-616") used by Pfizer in the manufacture of its active pharmaceutical ingredient 
nirmatrelvir for its COVID-19 antiviral therapeutic, PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets).  Revenues in 
2022 and in future years from our sales of CDX-616 to Pfizer are subject to a number of factors which are outside of 
our control and may not materialize.  

Starting the first and second quarters of 2021, we began to receive purchase orders from Pfizer, Inc. (“Pfizer”) for 

large quantities of our proprietary enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical 
intermediate for its proprietary active pharmaceutical ingredient, nirmatrelvir.  Pfizer markets, sells and distributes 
nirmatrelvir, in combination with the active pharmaceutical ingredient ritonavir, as its PAXLOVID™ (nirmatrelvir tablets; 
ritonavir tablets) product, which received emergency use authorization (“EUA”) by the U.S. Food and Drug Administration 
(“FDA”) in late 2021 for the treatment of COVID-19 infections in humans. 

In 2021, we recognized $34.5 million in revenue from the sale of quantities of CDX-616 to Pfizer.  In addition, as of 

December 31, 2021, we have received additional purchase orders from Pfizer for delivery of a significant quantity of CDX-
616 in 2022. We have received and currently expect to receive additional purchase orders from Pfizer for significant 
quantities of CDX-616 during the course of 2022 for delivery in 2022 and 2023. 

Revenues in 2022 and in future years from our sales of CDX-616 to Pfizer and other potential customers (including 
sublicensees of Pfizer technology from The Medicines Patent Pool) are subject to a number of factors which are outside of 
our control, including, without limitation, the following, all of which could reduce or eliminate our sales of CDX-616, and 
therefore materially and adversely affect our business, results of operations and financial condition: 

• 

•

Pfizer has no future binding commitment to purchase any particular quantity or quantities of CDX-616 from 
us, and we are dependent upon Pfizer continuing to place orders with us (whether on a spot basis or under a 
long term agreement, when and if executed) for their requirements, if any, for CDX-616; 

to our knowledge, sublicensees of Pfizer technology from The Medicines Patent Pool (MPP) have no 
obligation to purchase CDX-616 from us under their sublicenses with MPP; 

the EUA granted by the FDA for the use of PAXLOVID™ for the treatment of COVID-19 infections in 
humans could be withdrawn at any time; 

future vaccine development and usage and the development and usage of other new therapies for the 
treatment or elimination of COVID-19 may eliminate or reduce demand for PAXLOVID™; 

new variants of COVID-19 may emerge which PAXLOVID™ is not effective in treating; 

Pfizer may not ultimately receive full marketing authorization for PAXLOVID™ from the FDA and other 
international regulatory authorities; 

Pfizer could reformulate or make changes in the manufacturing process for nirmatrelvir which would 
eliminate or reduce demand for the use of CDX-616 in its manufacture; 

sublicensees of Pfizer technology for the manufacture, sale and distribution of PAXLOVID™ from the MPP 
may not utilize CDX-616 in the manufacture of nirmatrelvir; 

national and regional governmental authorities (including those of the United States government) may 
mandate that raw materials and intermediates used in the manufacture of PAXLOVID™ to be marketed, sold 
and distributed within the borders of that country be domestically produced, which could eliminate or reduce 
demand for the use of CDX-616 in such country; and 

•  we may be unable (because of lack of available manufacturing capacity at our contract manufacturers, supply 
chain disruptions or an inability to obtain applicable regulatory approvals) to manufacture the quantities of 
CDX-616 that Pfizer may desire to purchase from us. 

27 

 
We do not have a long term sale and purchase agreement with Pfizer for CDX-616.  \Whether or not a long term-
purchase and sale agreement is executed, we currently expect that future orders for quantities of CDX-616 by Pfizer will 
continue to be based on the needs of Pfizer for quantities of CDX-616 and there will be no minimum purchase 
obligation on the part of Pfizer. If Pfizer ceases to issue or delays the issuance of orders for CDX-616, our results of 
operations and financial condition will be materially and adversely affected. 

As of December 31, 2021, we have not yet executed a long term sale and purchase agreement with Pfizer for CDX-
616. All of the orders for CDX-616 that we have received from Pfizer to date have been in the form of purchase orders for 
individual deliveries of quantities of CDX-616 at mutually agreed upon pricing. Whether or not a long term purchase and 
sale agreement is executed, we currently expect that future orders for quantities of CDX-616 by Pfizer will continue to be 
based on the then current needs of Pfizer for quantities of CDX-616 and there will be no minimum purchase obligation on 
the part of Pfizer. If Pfizer's demand for CDX-616 declines or is eliminated, and Pfizer ceases to issue or delays the 
issuance of orders for CDX-616, our results of operations and financial condition will be materially and adversely affected.  

We have a history of net losses and we may not achieve or maintain profitability.  

We have incurred net losses since our inception, including losses of $21.3 million in 2021, $24.0 million in 2020 and 

$11.9 million in 2019. As of December 31, 2021 and 2020, we had an accumulated deficit of $387.7 million and 
$366.4 million, respectively. If we are unable to expand our business, through new or expanded collaborations, 
development of new products or services, or increased sales of existing products and services, our net losses may increase 
and we may never achieve profitability. In addition, some of our collaboration agreements, including our collaboration with 
Nestlé Health Science and Takeda, and our performance enzyme agreements, including the agreements with GSK, Merck 
and Novartis, provide for milestone payments, usage payments, and/or future royalty payments, which we will only receive 
if we and our collaborators develop and commercialize products. We also may fund development of additional proprietary 
performance enzymes and/or biotherapeutic products. There can be no assurance that any of these products will become 
commercially viable or that we will ever achieve profitability on a quarterly or annual basis. If we fail to achieve 
profitability, or if the time required to achieve profitability is longer than we anticipate, we may not be able to continue our 
business. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or 
annual basis.  

We are dependent on our collaborators, and our failure to successfully manage these relationships could prevent us 
from developing and commercializing many of our products and achieving or sustaining profitability, and could lead to 
disagreements with our current or former collaborators. 

Our ability to maintain and manage collaborations in our markets is fundamental to the success of our business. We 

currently have license agreements, research and development agreements, supply agreements and/or distribution 
agreements with various collaborators. For example, we have ongoing collaborations and agreements with GSK, Merck, 
Novartis, Nestlé Health Science and Takeda that are important to our business and financial results. We may have limited 
or no control over the amount or timing of resources that any collaborator is able or willing to devote to our partnered 
products or collaborative efforts. Any of our collaborators may fail to perform its obligations. These collaborators may 
breach or terminate their agreements with us or otherwise fail to conduct their collaborative activities successfully and in a 
timely manner. Further, our collaborators may not develop products arising out of our collaborative arrangements or devote 
sufficient resources to the development, manufacture, marketing or sale of these products. Moreover, disagreements with a 
collaborator could develop, and any conflict with a collaborator could lead to litigation and could reduce our ability to enter 
into future collaboration agreements and negatively impact our relationships with one or more existing collaborators. If any 
of these events occur, especially if they occur in our collaborations with GSK, Merck, Novartis, Nestlé Health Science or 
Takeda, or if we fail to maintain our agreements with our collaborators, we may not be able to commercialize our existing 
and potential products or grow our business or generate sufficient revenues to support our operations, we may not receive 
contemplated milestone payments and royalties under the collaboration, and we may be involved in litigation. Our 
collaboration opportunities could be harmed and our financial condition and results of operations could be negatively 
affected if: 

•  we do not achieve our research and development objectives under our collaboration agreements in a timely 

manner or at all; 

•  we develop products and processes or enter into additional collaborations that conflict with the business 

objectives of our other collaborators; 

•  we, our collaborators and/or our contract manufacturers do not receive the required regulatory and other 

approvals necessary for the commercialization of the applicable product; 

28 

 
•  we disagree with our collaborators as to rights to intellectual property that are developed during the 

collaboration, or their research programs or commercialization activities; 

•  we are unable to manage multiple simultaneous collaborations; 

• 

• 

• 

• 

our collaborators or licensees are unable or unwilling to implement or use the technology or products that we 
provide or license to them; 

our collaborators become competitors of ours or enter into agreements with our competitors; 

our collaborators become unable or less willing to expend their resources on research and development or 
commercialization efforts due to general market conditions, their financial condition or other circumstances 
beyond our control; or  

our collaborators experience business difficulties, which could eliminate or impair their ability to effectively 
perform under our agreements. 

Even after collaboration relationships expire or terminate, some elements of the collaboration may survive. For 
instance, certain rights, licenses and obligations of each party with respect to intellectual property and program materials 
may survive the expiration or termination of the collaboration. Disagreements or conflicts between and among the parties 
could develop even though the collaboration has ended. These disagreements or conflicts could result in expensive 
arbitration or litigation, which may not be resolved in our favor. 

Finally, our business could be negatively affected if any of our collaborators or suppliers undergoes a change of control 

or were to otherwise assign the rights or obligations under any of our agreements. 

We are dependent on a limited number of customers, including Pfizer.  

Our current revenues are derived from a limited number of key customers. For the years ended December 31, 2021 and 

2020, customers that each individually contributed 10% or more of our total revenue accounted for 44% and 56% of our 
total revenues in 2021 and 2020, respectively. In particular, in 2021 Pfizer accounted for $34.5 million, or approximately 
33%, of our total revenue. We expect a limited number of customers to continue to account for a significant portion of our 
revenues for the foreseeable future. This customer concentration increases the risk of quarterly fluctuations in our revenues 
and operating results. The loss or reduction of business from one or a combination of our significant customers could, 
materially adversely affect our revenues, financial condition and results of operations. 

The ongoing COVID-19 pandemic has adversely affected and may continue in the future to, directly or indirectly, 

adversely affect our business, results of operations and financial condition. 

The COVID-19 pandemic has had, and continues to have, a significant impact globally, prompting governments and 

businesses to take unprecedented measures in response. In the United States, the COVID-19 pandemic has and may 
continue in the future to, directly or indirectly, adversely affect our business, results of operations and financial condition, 
including as a result of compliance with governmental orders governing the operation of businesses during the pandemic, 
the temporary closure of our Redwood City, California facilities from mid-March 2020 through the end of April 2020 and 
disruption of our research and development operations.  

The extent and severity of the impact on our business and clinical trials will be determined largely by the extent of 
disruptions in the supply chains for our products and product candidates; disruptions in access by patients to therapies for 
which our products are components of the supply chain; delays in the performance of research and development ("R&D") 
service work, and delays in current and future clinical trials that we or our collaboration partners may conduct. In addition, 
the impact of the COVID-19 pandemic on the operations of the FDA and other health authorities may delay potential 
approvals of product candidates for which our products are components of the supply chain. To date, we and our 
collaboration partners have been able to continue to supply our enzymes to our customers worldwide, however there can be 
no guarantee this will continue. Furthermore, our ability to provide future R&D services will continue to be impacted as a 
result of governmental orders and any disruptions in operations of our customers with whom we collaborate. We believe 
that these disruptions have had a minimal impact on our revenue for the year ended December 31, 2021. The extent to 
which the pandemic may impact our business operations and operating results will continue to remain highly dependent on 
future developments, which are uncertain and cannot be predicted with confidence. 

In the future, our business could be materially adversely affected, directly or indirectly, by the widespread outbreak of 
contagious disease, including the ongoing COVID-19 pandemic. National, state and local governments in affected regions 
have implemented and may continue to implement safety precautions, including quarantines, border closures, increased 
border controls, travel restrictions, governmental orders and shutdowns, business closures, cancellations of public 

29 

 
gatherings and other measures. Organizations and individuals are taking additional steps to avoid or reduce infection, 
including limiting travel and staying home from work. These measures are disrupting normal business operations both in 
and outside of affected areas and have had significant negative impacts on businesses and financial markets worldwide. 

The potential impact and duration of COVID-19 or another pandemic or public health crisis has had and could 

continue to have, significant repercussions across regional, national and global economies and financial markets, and could 
trigger a period of regional, national and global economic slowdown or regional, national or global recessions. The 
outbreak of COVID-19 in many countries continues to adversely impact regional, national and global economic activity 
and has contributed to significant volatility and negative pressure in financial markets. As a result, we may experience 
difficulty accessing debt and equity capital on attractive terms, or at all, due to the severe disruption and instability in the 
global financial markets. In addition, our customers may terminate or amend their agreements for the purchase of our 
products or services due to bankruptcy, lack of liquidity, lack of funding, operational failures, or other reasons. 

We continue to monitor our operations and applicable government recommendations, and we have made modifications 

to our normal operations because of the COVID-19 pandemic, including requiring most office-based employees to work 
remotely. Notwithstanding these measures, the COVID-19 pandemic could affect the health and availability of our 
workforce as well as those of the third parties we rely on taking similar measures. If members of our management and 
other key personnel in critical functions across our organization are unable to perform their duties or have limited 
availability due to COVID-19, we may not be able to execute on our business strategy and/or our operations may be 
negatively impacted. We may also experience limitations in employee resources, including because of sickness of 
employees or their families or the desire of employees to avoid contact with individuals or large groups of people. In 
addition, we have experienced and will continue to experience disruptions to our business operations resulting from 
quarantines, self-isolations and other restrictions on the ability of our employees to perform their jobs. 

While it is not possible at this time to estimate the entirety of the impact that the COVID-19 pandemic will have on 
our business, operations, employees, customers, suppliers or our collaboration partners, the continued spread of COVID-19 
and the prevalence of more contagious and or virulent variants such as the Delta and Omicron variants, measures taken by 
governments, actions taken to protect employees and the broad impact of the pandemic on all business activities may 
materially and adversely affect our business, results of operations and financial condition. 

Our product supply agreements with customers have finite duration, may not be extended or renewed and generally 

do not require the customer to purchase any particular quantity or quantities of our products. 

Our product supply agreements with customers generally have a finite duration, may not be extended or renewed and 
generally do not require the customer to purchase any particular quantity or quantities of our products. While our products 
are not considered commodities and may not be easily substituted for by our customers, particularly when our products are 
used in the manufacture of active pharmaceutical ingredients, our customers may nevertheless terminate or fail to renew 
their product supply agreements with us or significantly curtail their purchases thereunder under certain circumstances. 
Any such termination or reduction could materially adversely affect our revenues, financial condition and results of 
operations. For the year ended December 31, 2021, we derived a majority of our product revenue from these product 
supply agreements. 

30 

 
 
 
With respect to customers purchasing our products for the manufacture of active pharmaceutical ingredients 
("API") for which they have exclusivity due to patent protection, the termination or expiration of such patent protection 
and any resulting generic competition may materially and adversely affect our revenues, financial condition or results 
of operations. 

With respect to customers purchasing our products for the manufacture of API, or lead to the manufacture of API, for 
which exclusivity due to patent protection has or is about to expire, we can expect that the quantity of our products sold to 
such customers for such products may decline as generic competition for the API increases. While we anticipate that we 
may, in some cases, also be able to sell products to these generic competitors for the manufacture of these APIs, or lead to 
the manufacture of these APIs, the overall effect on our revenues, financial condition and results of operations could be 
materially adverse. 

We are dependent on a limited number of contract manufacturers for large scale production of substantially all of 

our enzymes, including CDX-616. We are working to qualify new contract manufacturers to produce certain of our 
enzymes, including CDX-616, however those efforts may not be successful and therefore we may experience limitations 
on our ability to supply our enzymes to customers. 

Manufacturing of our enzymes is conducted primarily in four locations: our in-house facility in Redwood City, 
California, and at three third-party contract manufacturing organizations, Lactosan GmbH & Co. KG (“Lactosan”), in 
Kapfenberg, Austria, ACS Dobfar S.p.A. (“ACSD”) (formerly known as DPhar S.p.A.), in Anagni, Italy, and Alphazyme 
LLC in Florida, United States. Generally, we perform smaller scale manufacturing in-house and outsource the larger scale 
manufacturing to these contract manufacturers. We have limited internal capacity to manufacture enzymes. As a result, we 
are dependent upon the performance and capacity of third-party manufacturers for the larger scale manufacturing of the 
enzymes used in our pharmaceutical and fine chemicals business. 

Accordingly, we face risks of difficulties with, and interruptions in, performance by third party manufacturers, the 
occurrence of which could adversely impact the availability, launch and/or sales of our enzymes in the future. Enzyme 
manufacturing capacity limitations at our third party manufacturers and manufacturing delays could negatively affect our 
business, reputation, results of operations and financial condition. The failure of any contract manufacturer to supply us our 
required volumes of enzyme on a timely basis, or to manufacture our enzymes in compliance with our specifications or 
applicable quality requirements or in volumes sufficient to meet demand, would adversely affect our ability to sell 
pharmaceutical and fine and complex chemicals products, could harm our relationships with our collaborators or customers 
and could negatively affect our revenues and operating results. We may be forced to secure alternative sources of supply, 
which may be unavailable on commercially acceptable terms, and could cause delays in our ability to deliver products to 
our customers, increase our costs and decrease our profit margins. 

We currently have supply agreements in place with Lactosan, ACSD, and Alphazyme. In the absence of a supply 
agreement, a contract manufacturer will be under no obligation to manufacture our enzymes and could elect to discontinue 
their manufacture at any time. If we require additional manufacturing capacity and are unable to obtain it in sufficient 
quantity, we may not be able to increase our product sales, or we may be required to make substantial capital investments 
to build that capacity or to contract with other manufacturers on terms that may be less favorable than the terms we 
currently have with our suppliers. If we choose to build our own additional manufacturing facility, it could take two years 
or longer before our facility is able to produce commercial volumes of our enzymes. Any resources we expend on acquiring 
or building internal manufacturing capabilities could be at the expense of other potentially more profitable opportunities. In 
addition, if we contract with other manufacturers, we may experience delays of several months in qualifying them, which 
could harm our relationships with our collaborators or customers and could negatively affect our revenues or operating 
results. 

If we are unable to develop and commercialize new products for the pharmaceutical, fine chemicals, 

biotherapeutics, diagnostics and life science tools markets, our business and prospects will be harmed. 

We plan to launch new products for the pharmaceutical, fine chemicals, biotherapeutics, diagnostics and other life 

science tools markets. These efforts are subject to numerous risks, including the following:  

• 

customers in these markets may be reluctant to adopt new manufacturing processes that use our enzymes;  

•  we may be unable to successfully develop the enzymes or manufacturing processes for our products in a 

timely and cost-effective manner, if at all;  

31 

 
•  we may face difficulties in transferring the developed technologies to our customers and the contract 

manufacturers that we may use for commercial scale production of intermediates and enzymes in these 
markets;  

• 

• 

the contract manufacturers that we may use may be unable to scale their manufacturing operations to meet the 
demand for these products and we may be unable to secure additional manufacturing capacity;  

customers may not be willing to purchase these products for these markets from us on favorable terms, if at 
all;  

•  we may face product liability litigation, unexpected safety or efficacy concerns and product recalls or 

withdrawals;  

• 

• 

changes in laws or regulations relating to the pharmaceutical industry or the industries into which we sell our 
fine chemicals products, including the food industry, could cause us to incur increased costs of compliance or 
otherwise harm our business;  

our customers’ products may experience adverse events or face competition from new products, which would 
reduce demand for our products;  

•  we may face pressure from existing or new competitive products; and  

•  we may face pricing pressures from existing or new competitors, some of which may benefit from 

government subsidies or other incentives. 

Our biotherapeutic programs are early stage, highly regulated and expensive. Our ability to obtain additional 
development partners or additional funding for the programs, to advance our product candidates to clinical trials and to 
ultimately receive regulatory approvals is highly uncertain. 

We are developing and have developed novel biotherapeutic candidates, including CDX-6114, the novel oral enzyme 

product candidate for the treatment of PKU that we licensed to Nestlé Health Science. We are also developing protein 
sequences for use in gene therapy products for Fabry Disease, Pompe Disease, an undisclosed blood factor deficiency and a 
certain undisclosed rare genetic disorder for Takeda. The successful development of biotherapeutic candidates involves 
many risks and uncertainties, requires long timelines and may lead to uncertain results. In addition, drug development is 
highly regulated and requires areas of expertise and capital resources we do not currently possess. In order to market a 
biologic product in the United States, we or our collaborators must undergo the following process required by the FDA: 

• 

• 

• 

• 

• 

• 

• 

• 

completion of extensive preclinical laboratory tests and preclinical animal studies, all performed in 
accordance with GLP requirements; 

submission to the FDA of an IND, which must become effective before human clinical studies may begin in 
the United States; 

approval by an independent IRB representing each clinical site before the clinical study may be initiated at 
the site; 

performance of adequate and well-controlled human clinical studies (generally divided into three phases) in 
accordance with GCP requirements to establish the safety, purity and potency (or efficacy) of the product 
candidate for each proposed indication; 

preparation of and submission to the FDA of a BLA after completion of all clinical studies; 

potential review of the product candidate by an FDA advisory committee; 

satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities where the product 
candidate is produced to assess compliance with cGMP requirements; and 

FDA review and approval of a BLA prior to any commercial marketing or sale of the product in the United 
States. 

If we fail to comply with applicable FDA or other regulatory requirements at any time during the drug development 

process, clinical testing, the approval process or after approval, we may become subject to administrative or judicial 
penalties, including the FDA’s refusal to approve a pending application, withdrawal of an approval, warning letters, product 
recalls, and additional enforcement actions. 

Our efforts to advance our biotherapeutic candidates that we develop are subject to numerous risks, including the 

following: 

32 

 
•  The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time 

consuming and the results are inherently unpredictable. If we are ultimately unable to obtain regulatory 
approval for biotherapeutic product candidates, our business will be harmed. To obtain regulatory approval to 
market any product candidate, preclinical studies and costly and lengthy clinical trials are required, and the 
results of the studies and trials are highly uncertain. A failure of one or more preclinical or clinical trials can 
occur at any stage, and many companies that have believed their drug candidates performed satisfactorily in 
preclinical and clinical testing have nonetheless failed to obtain marketing approval of their product 
candidates. 

•  We may find it difficult to enroll patients in our clinical trials for product candidates. Any enrollment 

difficulties could delay clinical trials and any potential product approval. 

•  We may experience difficulty or delay in obtaining the FDA’s acceptance of an IND for product candidates 
we may seek to enter into clinical development, which would delay initiation of Phase 1 clinical testing. 
Delays in the commencement or completion of clinical testing could significantly affect our product 
development costs or the product development costs of our present and any future collaborators. We do not 
know whether planned clinical trials will begin on time or be completed on schedule, if at all. The 
commencement and completion of clinical trials can be delayed for a number of reasons. For example, a 
clinical trial may be suspended or terminated by us, by the IRB of the institution in which such trial is being 
conducted, or by the FDA due to a number of factors, including unforeseen safety issues, changes in 
governmental regulations or lack of adequate funding to continue the clinical trial. 

•  We have limited experience in drug development or regulatory matters related to drug development. As a 

result, we rely or will rely on third parties to conduct our preclinical and clinical studies, assist us with drug 
manufacturing and formulation and perform other tasks for us. If these third parties do not successfully carry 
out their responsibilities or comply with regulatory requirements, we may receive lower quality products or 
services, suffer reputational harm and not be able to obtain regulatory approval for product candidates. 

•  Our efforts to use CodeEvolver® protein engineering technology platform to generate new lead biotherapeutic 
candidates, whether under our collaborations with Nestlé Health Science, Takeda or otherwise, may not be 
successful in creating candidates of value. 

•  We will be exposed to potential product liability risks through the testing of experimental therapeutics in 

humans, which may expose us to substantial uninsured liabilities. 

•  Third parties may develop intellectual property that could limit our ability to develop, market and 

commercialize product candidates. 

•  Changes in methods of treatment of disease, such as gene therapy, could cause us to stop development of our 
product candidates or reduce or eliminate potential demand for CDX-6114, if approved, or any other product 
candidates that we may develop in the future. 

If either Nestlé Health Science or Takeda terminate their development programs under their respective license 
agreements with us, any potential revenue from those license agreements will be significantly reduced or non-existent, 
and our results of operations and financial condition will be materially and adversely affected. 

We have invested significant time and financial resources in the development of CDX-6114 and other product 

candidates for the treatment of HPA now included in the Nestlé License Agreement as well as in the development of 
candidates for the treatment of Fabry disease and Pompe disease which are now included in the Takeda Agreement. 

Under the Nestlé License Agreement, we are eligible to receive payments from Nestlé Health Science that include (i) 

development and approval milestones of up to $85.0 million, (ii) sales-based milestones of up to $250.0 million in the 
aggregate, which aggregate amount is achievable if net sales exceed $1.0 billion in a single year, and (iii) tiered royalties, at 
percentages ranging from the mid-single digits to low double-digits, of net sales of product. Under the Takeda Agreement, 
we are eligible to earn potential payments that include (i) reimbursement of research and development fees and preclinical 
development milestone payments for the three initial programs of $10.5 million, in aggregate, and $8.3 million for the 
fourth program, (ii) clinical development and commercialization-based milestone, per target gene, of up to $100.0 million, 
and (iii) tiered royalty payments based on net sales of applicable products at percentages ranging from the mid-single digits 
to low single-digits. While we have received milestone payments under the Nestlé License Agreement to date there is no 
guarantee that we will receive further milestone payments under the Nestlé Agreement or Takeda Agreement in the future. 

Under the Nestle Agreement and the Takeda Agreement, either Nestlé Health Science and Takeda, as applicable, may 

each terminate the entire agreement or specified programs thereunder at will under certain circumstances as described in 

33 

 
more detail under “Item 1. Business--Our Market Opportunities--Pharmaceutical Market--Our Solutions for the 
Pharmaceutical Market--Biotherapeutic Product Discovery and Development” in this Annual Report on Form 10-K.  

If Nestlé Health Science terminates its rights and obligations with respect to the Nestlé License Agreement and/or 
Takeda terminates its rights and obligations with respect to the Takeda Agreement, then depending on the timing of such 
event: 

• 

• 

the development of our product candidates subject to the respective agreements may be terminated or 
significantly delayed; 

our cash expenditures could increase significantly if it is necessary for us to hire additional employees and 
allocate scarce resources to the development and commercialization of product candidates; 

•  we would bear all of the risks and costs related to the further development and commercialization of product 

candidates that were previously the subject of the respective agreements, including the reimbursement of third 
parties; and 

• 

in order to fund further development and commercialization of new product candidates or programs, we may 
need to seek out and establish alternative collaboration arrangements with third-party partners; this may not 
be possible, or we may not be able to do so on terms which are acceptable to us, in which case it may be 
necessary for us to limit the size or scope of one or more of our programs or increase our expenditures and 
seek additional funding by other means. 

Our efforts to deploy our technology platform in the fine chemicals market may fail. 

We have recently begun to use our CodeEvolver® protein engineering technology platform to develop new products in 

the fine chemicals markets. We do not know if we can successfully compete in this new market. This new market is well 
established and consists of numerous large, well-funded entrenched market participants who have long and established 
track records and customer relationships. We have currently developed products in the food sector of this market and these 
products, or any other products that we may develop in the future for the fine chemicals market may not succeed in 
displacing current products. If we succeed in commercializing new products for the fine chemicals market, we may not 
generate significant revenues and cash flows from these activities. The failure to successfully deploy products in the fine 
chemicals space may limit our growth and have a material adverse effect on our financial condition, operating results and 
business prospects.  

We may need additional capital in the future in order to expand our business.  

Our future capital requirements may be substantial, particularly as we continue to develop our business. Although we 
believe that, based on our current level of operations, our existing cash, cash equivalents and equity securities will provide 
adequate funds for ongoing operations, planned capital expenditures and working capital requirements for at least the next 
12 months, we may need additional capital if our current plans and assumptions change. Our need for additional capital 
will depend on many factors, including the financial success of our performance enzyme business, our spending to develop 
and commercialize new and existing products and the amount of collaboration funding we may receive to help cover the 
cost of such expenditures, the effect of any acquisitions of other businesses, technologies or facilities that we may make or 
develop in the future, our spending on new market opportunities, including opportunities in the fine chemicals markets, and 
the filing, prosecution, enforcement and defense of patent claims. If our capital resources are insufficient to meet our 
capital requirements, and we are unable to enter into or maintain collaborations with partners that are able or willing to 
fund our development efforts or commercialize any products that we develop or enable, we will have to raise additional 
funds to continue the development of our technology and products and complete the commercialization of products, if any, 
resulting from our technologies. In addition, we may choose to raise additional capital due to market conditions or strategic 
considerations even if we believe we have sufficient funds for our current or future operating plans. We may seek to obtain 
such additional capital through equity offerings, debt financings, credit facilities and/or strategic collaborations. If future 
financings involve the issuance of equity securities, our existing stockholders would suffer dilution. If we raise debt 
financing or enter into credit facilities, we may be subject to restrictive covenants that limit our ability to conduct our 
business. Strategic collaborations may also place restrictions on our business. We may not be able to raise sufficient 
additional funds on terms that are favorable to us, if at all. If we fail to raise sufficient funds and fail to generate sufficient 
revenues to achieve planned gross margins and to control operating costs, our ability to fund our operations, take advantage 
of strategic opportunities, develop products or technologies, or otherwise respond to competitive pressures could be 
significantly limited. If this happens, we may be forced to delay or terminate research or development programs or the 
commercialization of products resulting from our technologies, curtail or cease operations or obtain funds through 
collaborative and licensing arrangements that may require us to relinquish commercial rights, or grant licenses on terms 

34 

 
that are not favorable to us. If adequate funds are not available, we will not be able to successfully execute our business 
plan or continue our business. 

We have investments in non-marketable securities, which may subject us to significant impairment charges. 

We have investments in illiquid non-marketable equity securities acquired in private transactions. At December 31, 
2021, 5.7% of our consolidated assets consisted of investment securities, which are illiquid investments. Investments in 
illiquid, or non-marketable, securities are inherently risky and difficult to value. We account for our non-marketable equity 
securities under the measurement alternative. Under the measurement alternative, the carrying value of our non-marketable 
equity investments is adjusted to fair value for observable transactions for identical or similar investments of the same 
issuer or impairment. We evaluate our investment in non-marketable securities when circumstances indicate that we may 
not be able to recover the carrying value. We may impair these securities and establish an allowance for a credit loss when 
we determine that there has been an “other-than-temporary” decline in estimated fair value of the equity security compared 
to its carrying value. The impairment analysis requires significant judgment to identify events or circumstances that would 
likely have a material adverse effect on the fair value of the investment. Because over 5% of our total assets consisted of 
non-marketable investment securities, any future impairment charges from the write down in value of these securities could 
have a material adverse effect on our financial condition or results of operations. 

Competitors and potential competitors who have greater resources and experience than we do may develop products 

and technologies that make ours obsolete or may use their greater resources to gain market share at our expense.  

The biocatalysis industry and each of our target markets are characterized by rapid technological change. Our future 
success will depend on our ability to maintain a competitive position with respect to technological advances. In addition, as 
we enter new markets, we will face new competition and will need to adapt to competitive factors that may be different 
from those we face today.  

We are aware that other companies, including Royal DSM, N.V. (“DSM”), BASF, Bayer and Novozymes have 
alternative methods for obtaining and generating genetic diversity or use mutagenesis techniques to produce genetic 
diversity. Academic institutions such as the California Institute of Technology, the Max Planck Institute and the Austrian 
Centre of Industrial Biotechnology are also working in this field. Technological development by others may result in our 
products and technologies, as well as products developed by our customers using our biocatalysts, becoming obsolete.  

Our primary competitors in the performance enzymes for pharmaceutical products are companies marketing either 
conventional, non-enzymatic processes or biocatalytic enzymes to manufacturers of pharmaceutical intermediates and 
APIs, and also existing in-house technologies (both biocatalysts and conventional catalysts) within our client and potential 
client companies. The principal methods of competition and competitive differentiation in this market are price, product 
quality and performance, including manufacturing yield, safety and environmental benefits, and speed of delivery of 
product. Pharmaceutical manufacturers that use biocatalytic processes can face increased competition from manufacturers 
that use more conventional processes and/or manufacturers that are based in regions (such as India and China) with lower 
regulatory, safety and environmental costs. 

The market for the manufacture and supply of APIs and intermediates is large with many established companies. These 

companies include many of our large innovator and generic pharmaceutical customers, such as Merck, GSK, Novartis, 
Pfizer, Bristol-Myers, Kyorin, Urovant and Teva which have significant internal research and development efforts directed 
at developing processes to manufacture APIs and intermediates. The processes used by these companies include classical 
conventional organic chemistry reactions, chemo catalytic reactions, biocatalytic reactions or combinations thereof. Our 
biocatalytic based manufacturing processes must compete with these internally developed routes. Additionally, we also 
face competition from companies developing and marketing conventional catalysts such as Solvias Inc., BASF and 
Takasago International Corporation. 

The market for supplying enzymes for use in pharmaceutical manufacturing is quite fragmented. There is competition 

from large industrial enzyme companies, such as Novozymes, and Dupont, as well as subsidiaries of larger contract 
research/contract manufacturing organizations (“CRO/CMO”), such as DSM, Cambrex Corporation, Lonza, WuXi STA, 
and Almac Group Ltd. Some fermentation pathway design companies, like Ginkgo Bioworks and Zymergen, whose 
traditional focus has been to design microorganisms that express small molecule chemicals, could extend into designing 
organisms that express enzymes. There is also competition in the enzyme customization and optimization area from several 
smaller companies, such as BRAIN AG, Arzeda, c-LEcta GmbH and Evocatal GmbH. 

We entered the fine chemicals market in 2013, by applying our protein engineering technology in the food market. We 
face similar forms of competition in this market as in the pharmaceutical markets with the exception that the risk of losing 

35 

 
opportunities to larger competitors in fine chemicals is greater given the larger scale of opportunities available in the fine 
chemicals market compared to the pharmaceutical market. Our significant competitors in the fine chemicals markets 
include companies that have been in these marketplaces for many years, such as DuPont Industrial Biosciences (DuPont 
Genencor), DSM, Novozymes and A.B. Enzymes. These companies have greater resources in these markets than we do 
and have long-term supply arrangements already in place with customers. Our ability to compete in these markets may be 
limited by our relatively late entrance. We also face competition in both the fine chemicals and pharmaceutical markets 
from emerging companies offering whole cell metabolic pathway approaches to these markets. 

There are numerous companies that participate in the biotherapeutics market generally and the PKU market 
specifically. Many of these companies are large, successful and well-capitalized. BioMarin Pharmaceutical Inc. 
(“BioMarin”) and Daiichi Sankyo Company market Kuvan® in the United States, Europe and Japan for the treatment of a 
certain type of PKU. In addition, BioMarin gained US FDA approval in 2018 and began commercial sales of PalynziqTM as 
an injectable enzyme substitution therapy for the potential treatment of PKU. Several companies, i.e., Synlogic, Homology 
Medicines, and Rubius have reported clinical efforts to develop biotherapeutic candidates for PKU. Beyond targeting PKU, 
Takeda (who recently acquired Shire Plc), Genzyme / Sanofi S.A., BioMarin, and other companies market or are actively 
developing new enzyme therapeutics. There are numerous companies that are developing other forms of therapeutics, such 
as small molecules, gene therapies, as well as therapies based on gene editing, which could compete with biotherapeutics. 

Our ability to compete successfully in any of these markets will depend on our ability to develop proprietary products 
that reach the market in a timely manner and are technologically superior to and/or are less expensive than other products 
on the market. Many of our competitors have substantially greater production, financial, research and development, 
personnel and marketing resources than we do. They also started developing products earlier than we did, which may allow 
them to establish blocking intellectual property positions or bring products to market before we can. In addition, certain of 
our competitors may also benefit from local government subsidies and other incentives that are not available to us. As a 
result, our competitors may be able to develop competing and/or superior technologies and processes, and compete more 
aggressively and sustain that competition over a longer period of time than we could. Our technologies and products may 
be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one or 
more of our competitors. We cannot be certain that any products we develop in the future will compare favorably to 
products offered by our competitors or that our existing or future products will compare favorably to any new products that 
are developed by our competitors. As more companies develop new intellectual property in our markets, the possibility of a 
competitor acquiring patent or other rights that may limit our products or potential products increases, which could lead to 
litigation.  

Our limited resources relative to many of our competitors may cause us to fail to anticipate or respond adequately to 

new developments and other competitive pressures. This failure could reduce our competitiveness and market share, 
adversely affect our results of operations and financial position, and prevent us from obtaining or maintaining profitability.  

Ethical, legal and social concerns about genetically engineered products and processes could limit or prevent the 

use of our products, processes, and technologies and limit our revenues.  

Some of our products and processes are genetically engineered or involve the use of genetically engineered products or 

genetic engineering technologies. If we and/or our collaborators are not able to overcome the ethical, legal, and social 
concerns relating to genetic engineering, our products and processes may not be accepted. Any of the risks discussed below 
could result in increased expenses, delays, or other impediments to our programs or the public acceptance and 
commercialization of products and processes dependent on our technologies or inventions. Our ability to develop and 
commercialize one or more of our technologies, products, or processes could be limited by the following factors:  

• 

• 

• 

public attitudes about the safety and environmental hazards of, and ethical concerns over, genetic research 
and genetically engineered products and processes, which could influence public acceptance of our 
technologies, products and processes;  

public attitudes regarding, and potential changes to laws governing ownership of genetic material, which 
could harm our intellectual property rights with respect to our genetic material and discourage collaborators 
from supporting, developing, or commercializing our products, processes and technologies; and  

governmental reaction to negative publicity concerning genetically modified organisms, which could result in 
greater government regulation of genetic research and derivative products. The subject of genetically 
modified organisms has received negative publicity, which has aroused public debate. This adverse publicity 
could lead to greater regulation and trade restrictions on imports of genetically altered products. The 
biocatalysts that we develop have significantly enhanced characteristics compared to those found in naturally 
occurring enzymes or microbes. While we produce our biocatalysts only for use in a controlled industrial 

36 

 
environment, the release of such biocatalysts into uncontrolled environments could have unintended 
consequences. Any adverse effect resulting from such a release could have a material adverse effect on our 
business and financial condition, and we may have exposure to liability for any resulting harm.  

If we engage in any acquisitions, we will incur a variety of costs and may potentially face numerous risks that could 

adversely affect our business and operations.  

We have made acquisitions in the past, and if appropriate opportunities become available, we expect to acquire 
additional businesses, assets, technologies, or products to enhance our business in the future. For example, in October 
2010, we acquired substantially all of the patents and other intellectual property rights associated with Maxygen’s directed 
evolution technology.  

In connection with any future acquisitions, we could:  

• 

• 

• 

• 

issue additional equity securities, which would dilute our current stockholders;  

incur substantial debt to fund the acquisitions;  

use our cash to fund the acquisitions; or  

assume significant liabilities including litigation risk.  

Acquisitions involve numerous risks, including problems integrating the purchased operations, technologies or 
products, unanticipated costs and other liabilities, diversion of management’s attention from our core businesses, adverse 
effects on existing business relationships with current and/or prospective collaborators, customers and/or suppliers, risks 
associated with entering markets in which we have no or limited prior experience and potential loss of key employees. We 
do not have extensive experience in managing the integration process and we may not be able to successfully integrate any 
businesses, assets, products, technologies, or personnel that we might acquire in the future without a significant 
expenditure of operating, financial and management resources, if at all. The integration process could divert management’s 
time from focusing on operating our business, result in a decline in employee morale and cause retention issues to arise 
from changes in compensation, reporting relationships, future prospects or the direction of the business. Acquisitions may 
also require us to record goodwill and non-amortizable intangible assets that will be subject to impairment testing on a 
regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, 
and incur large and immediate write offs and restructuring and other related expenses, all of which could harm our 
operating results and financial condition. In addition, we may acquire companies that have insufficient internal financial 
controls, which could impair our ability to integrate the acquired company and adversely impact our financial reporting. If 
we fail in our integration efforts with respect to any of our acquisitions and are unable to efficiently operate as a combined 
organization, our business and financial condition may be adversely affected.  

We use hazardous materials in our business and we must comply with environmental laws and regulations. Any 
claims relating to improper handling, storage or disposal of these materials or noncompliance of applicable laws and 
regulations could be time consuming and costly and could adversely affect our business and results of operations.  

Our research and development and commercial processes involve the use of hazardous materials, including chemical, 

radioactive, and biological materials. Our operations also produce hazardous waste. We cannot eliminate entirely the risk of 
accidental contamination or discharge and any resultant injury from these materials. Federal, state, local and foreign laws 
and regulations govern the use, manufacture, storage, handling and disposal of, and human exposure to, these materials. We 
may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our 
liability may exceed our total assets. Although we believe that our activities comply in all material respects with 
environmental laws, there can be no assurance that violations of environmental, health and safety laws will not occur in the 
future as a result of human error, accident, equipment failure or other causes. Compliance with applicable environmental 
laws and regulations may be expensive, and the failure to comply with past, present, or future laws could result in the 
imposition of fines, third party property damage, product liability and personal injury claims, investigation and remediation 
costs, the suspension of production, or a cessation of operations, and our liability may exceed our total assets. Liability 
under environmental laws can be joint and several and without regard to comparative fault. Environmental laws could 
become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with 
violations, which could impair our research, development or production efforts and harm our business. In addition, we may 
have to indemnify some of our customers or suppliers for losses related to our failure to comply with environmental laws, 
which could expose us to significant liabilities.  

37 

 
Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to certain 

limitations.  

In general, under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), a corporation that 

undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating loss 
carryforwards (“NOLs”), to offset future taxable income. If the Internal Revenue Service challenges our analysis that our 
existing NOLs are not subject to limitations arising from previous ownership changes, our ability to utilize NOLs could be 
limited by Section 382 of the Code. Future changes in our stock ownership, some of which are outside of our control, could 
result in an ownership change under Section 382 of the Code. Furthermore, our ability to utilize NOLs of companies that 
we may acquire in the future may be subject to limitations. For these reasons, we may not be able to utilize a material 
portion of the NOLs reflected in our financial statements, even if we attain profitability. 

Risks Related to Government Regulation and Clinical Product Development 

We or our customers may not be able to obtain regulatory approval for the use of our products in food and food 

ingredients, if required, and, even if approvals are obtained, complying on an ongoing basis with the numerous 
regulatory requirements applicable to these products will be time-consuming and costly.  

The products that we develop for our food and food ingredient customers are, and any other products that we may 
develop for the food and food ingredients market will likely be, subject to regulation by various government agencies, 
including the FDA, state and local agencies and similar agencies outside the United States, as well as religious compliance 
certifying organizations. Food ingredients are regulated by the FDA either as food additives or as substances generally 
recognized as safe (“GRAS”). A substance can be listed or affirmed as GRAS by the FDA or self-affirmed by its 
manufacturer upon determination that independent qualified experts would generally agree that the substance is GRAS for 
a particular use. While we generally self-affirm GRAS status for the ingredients used in the products that we develop for 
the food market, our customer(s) may be required to submit a GRAS notification to FDA to establish that ingredients in a 
final commercial product may be considered GRAS. There can be no assurance that our customer(s) will not receive any 
objections from the FDA with respect to any GRAS notification our customer(s) may submit. If the FDA were to disagree 
with our customer’s determination that their commercial product and/or its ingredients are GRAS or otherwise compliant, 
the FDA could ask such customer to voluntarily withdraw the final commercial product from the market or could initiate 
legal action to halt its sale. Such actions by the FDA could have an adverse effect on our business, financial condition, and 
results of our operations. Food ingredients that are not GRAS are regulated as food additives and require FDA approval 
prior to commercialization or must be the subject of an existing food additive regulation. The food additive petition process 
for ingredients that are not already authorized by regulation is generally expensive and time consuming, with approval, if 
secured, potentially taking years. 

Our ongoing efforts to deploy our technology in the life science tools markets may fail. 

We have recently begun to use our CodeEvolver® protein engineering technology platform to develop new products 
for customers using NGS and PCR/qPCR for in vitro molecular diagnostic applications. while we have entered into some 
license agreements for products in this market, we do not know if we can successfully compete in this new market. This 
new market is well established and consists of numerous large, well-funded entrenched market participants who have long 
and established track records and customer relationships. In December 2019, we licensed our first proprietary enzyme for 
this market, EvoT4™ DNA ligase, which is designed to improve library preparation for NGS users, to Roche. This 
enzyme, and any products that we may develop in the future for this market, may not succeed in displacing current 
products. If we succeed in commercializing new products for this market, we may not generate significant revenues and 
cash flows from these activities. The failure to successfully deploy products on timely basis in this space may limit our 
growth and have a material adverse effect on our financial condition, operating results and business prospects. 

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming and 

inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our 
business will be substantially harmed. 

We and any collaborators are not permitted to commercialize, market, promote or sell any product candidate in the 

United States without obtaining marketing approval from the FDA. Foreign regulatory authorities impose similar 
requirements. The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable, but 
typically takes many years following the commencement of clinical trials and depends upon numerous factors, including 
substantial discretion of the regulatory authorities. In addition, approval policies, regulations or the type and amount of 
clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and 

38 

 
may vary among jurisdictions. To date, neither we nor our collaborators have submitted a BLA to FDA or similar drug 
approval submissions to comparable foreign regulatory authorities for any product candidate. We and any collaborators 
must complete additional preclinical or nonclinical studies and clinical trials to demonstrate the safety, purity and potency 
(or efficacy) of our product candidates in humans to the satisfaction of the regulatory authorities before we will be able to 
obtain these approvals. Our product candidates could fail to receive regulatory approval for many reasons, including the 
following: 

• 

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our 
or our collaborators’ clinical trials; 

•  we or our collaborators may be unable to demonstrate to the satisfaction of the FDA or comparable foreign 

regulatory authorities that a product candidate is safe and effective for its proposed indication; 

• 

the results of clinical trials may not meet the level of statistical significance required by the FDA or 
comparable foreign regulatory authorities for approval; 

•  we or our collaborators may be unable to demonstrate that a product candidate’s clinical and other benefits 

outweigh its safety risks; 

• 

• 

• 

• 

• 

the FDA or comparable foreign regulatory authorities may disagree with our or our collaborators’ 
interpretation of data from preclinical studies or clinical trials; 

the data collected from clinical trials of product candidates may not be sufficient to support the submission of 
a BLA to obtain regulatory approval in the United States or elsewhere; 

the FDA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or 
facilities of third-party manufacturers with which we or our collaborators contract for clinical and commercial 
supplies; 

the FDA or comparable foreign regulatory authorities may fail to approve the companion diagnostics we 
contemplate developing with collaborators; and 

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly 
change in a manner rendering our or our collaborators’ clinical data insufficient for approval. 

This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to 

obtain regulatory approval to market our product candidates, which would significantly harm our business, results of 
operations and prospects. In addition, even if we were to obtain approval, regulatory authorities may approve any of our 
product candidates for fewer or more limited indications than we request, may impose significant limitations in the form of 
narrow indications, warnings, or a REMS. Regulatory authorities may not approve the price we or our collaborators intend 
to charge for products we may develop, may grant approval contingent on the performance of costly post-marketing 
clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or 
desirable for the successful commercialization of that product candidate. Any of the foregoing scenarios could materially 
harm the commercial prospects for our product candidates. 

Clinical trials are difficult to design and implement, expensive, time-consuming and involve an uncertain outcome, 
and the inability to successfully conduct clinical trials and obtain regulatory approval for our product candidates would 
substantially harm our business. 

Clinical testing is expensive and usually takes many years to complete, and its outcome is inherently uncertain. Failure 

can occur at any time during the clinical trial process, and product candidates in later stages of clinical trials may fail to 
show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. 
We do not know whether planned clinical trials will begin on time, need to be redesigned, recruit and enroll patients on 
time or be completed on schedule, or at all. Clinical trials can be delayed, suspended or terminated for a variety of reasons, 
including in connection with: 

• 

• 

• 

• 

the inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the 
initiation of clinical trials; 

applicable regulatory authorities disagreeing as to the design or implementation of the clinical trials; 

obtaining regulatory authorization to commence a trial; 

reaching an agreement on acceptable terms with prospective contract research organizations ("CROs"), and 
clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly 
among different CROs and trial sites; 

39 

 
• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

obtaining IRB approval at each site; 

developing and validating the companion diagnostic to be used in a clinical trial, if applicable; 

insufficient or inadequate supply or quality of product candidates or other materials necessary for use in 
clinical trials, or delays in sufficiently developing, characterizing or controlling a manufacturing process 
suitable for clinical trials; 

recruiting and retaining enough suitable patients to participate in a trial; 

having enough patients complete a trial or return for post-treatment follow-up; 

adding a sufficient number of clinical trial sites; 

inspections of clinical trial sites or operations by applicable regulatory authorities, or the imposition of a 
clinical hold; 

clinical sites deviating from trial protocol or dropping out of a trial; 

the inability to demonstrate the efficacy and benefits of a product candidate; 

discovering that product candidates have unforeseen safety issues, undesirable side effects or other 
unexpected characteristics; 

addressing patient safety concerns that arise during the course of a trial; receiving untimely or unfavorable 
feedback from applicable regulatory authorities regarding the trial or requests from regulatory authorities to 
modify the design of a trial; 

non-compliance with applicable regulatory requirements by us or third parties or changes in such regulations 
or administrative actions; 

suspensions or terminations by IRBs of the institutions at which such trials are being conducted, by the Data 
Safety Monitoring Board for such trial or by the FDA or other regulatory authorities due to a number of 
factors, including those described above; 

third parties being unable or unwilling to satisfy their contractual obligations to us; or 

changes in our financial priorities, greater than anticipated costs of completing a trial or our inability to 
continue funding the trial. 

In addition, disruptions caused by the COVID-19 pandemic may increase the likelihood that we encounter such 
difficulties or delays in initiating, enrolling, conducting or completing our planned and ongoing clinical trials. Many of the 
factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the 
denial of regulatory approval of our product candidates. Additionally, we or our collaborators may experience unforeseen 
events during or resulting from clinical trials that could delay or prevent receipt of marketing approval for or 
commercialization of product candidates. For example, clinical trials of product candidates may produce negative, 
inconsistent or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or 
abandon development programs. Regulators may also revise the requirements for approving the product candidates, or such 
requirements may not be as we anticipate. If we or our collaborators are required to conduct additional clinical trials or 
other testing of product candidates beyond those that we or our collaborators currently contemplate, if we or our 
collaborators are unable to successfully complete clinical trials or other testing of such product candidates, if the results of 
these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

incur unplanned costs; 

be delayed in obtaining or fail to obtain marketing approval for product candidates; 

obtain marketing approval in some countries and not in others; 

obtain marketing approval for indications or patient populations that are not as broad as intended or desired; 

obtain marketing approval with labeling that includes significant use or distribution restrictions or safety 
warnings, including boxed warnings; 

be subject to additional post-marketing testing requirements; 

be subject to changes in the way the product is administered; 

have regulatory authorities withdraw or suspend their approval of the product or impose restrictions on its 
distribution; 

be sued; or 

40 

 
 
• 

experience damage to our reputation. 

If we or our collaborators experience delays in the commencement or completion of our clinical trials, or if we or our 

collaborators terminate a clinical trial prior to completion, we may experience increased costs, have difficulty raising 
capital and/or be required to slow down the development and approval process timelines. Furthermore, the product 
candidates that are the subject of such trials may never receive regulatory approval, and their commercial prospects and our 
ability to generate product revenues from them could be impaired or not realized at all. 

Results of preclinical studies and early clinical trials of product candidates may not be predictive of results of later 

studies or trials. Our product candidates may not have favorable results in later clinical trials, if any, or receive 
regulatory approval. 

Preclinical and clinical drug development is expensive and can take many years to complete, and its outcome is 
inherently uncertain. Failure can occur at any time during the preclinical study or clinical trial process. Despite promising 
preclinical or clinical results, any product candidate can unexpectedly fail at any stage of preclinical or clinical 
development. The historical failure rate for product candidates in our industry is high. The results from preclinical studies 
or early clinical trials of a product candidate may not be predictive of the results from later preclinical studies or clinical 
trials, and interim results of a clinical trial are not necessarily indicative of final results. Product candidates in later stages 
of clinical trials may fail to show the desired safety and efficacy characteristics despite having progressed through 
preclinical studies and initial clinical trials.  

Many companies in the biopharmaceutical and biotechnology industries have suffered significant setbacks at later 

stages of development after achieving positive results in early stages of development, and we may face similar setbacks. 
These setbacks have been caused by, among other things, preclinical findings made while clinical trials were underway or 
safety or efficacy observations made in clinical trials, including previously unreported adverse events. Moreover, non-
clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed 
their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain 
regulatory approval. Even if any product candidates progress to clinical trials, these product candidates may fail to show 
the safety and efficacy in clinical development required to obtain regulatory approval, despite the observation of positive 
results in animal studies. Our or our collaborators’ failure to replicate positive results from early research programs and 
preclinical or greenhouse studies may prevent us from further developing and commercializing those or other product 
candidates, which would limit our potential to generate revenues from them and harm our business and prospects. 

For the foregoing reasons, we cannot be certain that any ongoing or future preclinical studies or clinical trials will be 

successful. Any safety or efficacy concerns observed in any one of our preclinical studies or clinical trials in a targeted area 
could limit the prospects for regulatory approval of product candidates in that and other areas, which could have a material 
adverse effect on our business and prospects.  

Even if we obtain regulatory approval for any products that we develop alone or with collaborators, such products 

will remain subject to ongoing regulatory requirements, which may result in significant additional expense. 

Even if products we develop alone or with collaborators receive regulatory approval, they will be subject to ongoing 
regulatory requirements for manufacturing, labeling, packaging, distribution, storage, advertising, promotion, sampling, 
record-keeping and submission of safety and other post-market information, among other things. Any regulatory approvals 
received for such products may also be subject to limitations on the approved indicated uses for which they may be 
marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing and 
surveillance studies. For example, the holder of an approved BLA in the United States is obligated to monitor and report 
adverse events and any failure of a product to meet the specifications in the BLA. In the United States, the holder of an 
approved BLA must also submit new or supplemental applications and obtain FDA approval for certain changes to the 
approved product, product labeling or manufacturing process. Similar provisions apply in the European Union. Advertising 
and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially 
applicable federal and state laws. Similarly, in the European Union any promotion of medicinal products is highly 
regulated and, depending on the specific jurisdiction involved, may require prior vetting by the competent national 
regulatory authority. In addition, product manufacturers and their facilities are subject to payment of user fees and 
continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP 
requirements and adherence to commitments made in the BLA or foreign marketing application.  

If we, our collaborators or a regulatory agency discovers previously unknown problems with a product such as adverse 

events of unanticipated severity or frequency or problems with the facility where the product is manufactured or disagrees 
with the promotion, marketing or labeling of that product, a regulatory agency may impose restrictions relative to that 

41 

 
product, the manufacturing facility or us or our collaborators, including requiring recall or withdrawal of the product from 
the market or suspension of manufacturing. 

Moreover, if any of our product candidates are approved, our product labeling, advertising, promotion and distribution 

will be subject to regulatory requirements and continuing regulatory review. The FDA strictly regulates the promotional 
claims that may be made about drug products. In particular, a product may not be promoted for uses that are not approved 
by the FDA as reflected in the product’s approved labeling. If we or our collaborators fail to comply with applicable 
regulatory requirements following approval of any potential products we may develop, authorities may: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

issue an untitled enforcement letter or a warning letter asserting a violation of the law; 

seek an injunction, impose civil and criminal penalties, and impose monetary fines, restitution or 
disgorgement of profits or revenues; 

suspend or withdraw regulatory approval; 

suspend or terminate any ongoing clinical trials or implement requirements to conduct post-marketing studies 
or clinical trials; 

refuse to approve a pending BLA or comparable foreign marketing application (or any supplements thereto) 
submitted by us or our collaborators; 

restrict the labeling, marketing, distribution, use or manufacturing of products; 

seize or detain products or otherwise require the withdrawal or recall of products from the market; 

refuse to approve pending applications or supplements to approved applications that we or our collaborators 
submit; 

refuse to permit the import or export of products; or 

refuse to allow us or our collaborators to enter into government contracts. 

Any government investigation of alleged violations of law could require us to expend significant time and resources in 
response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our or 
our collaborators’ ability to commercialize products and our ability to generate revenues. 

In addition, the FDA’s policies, and policies of foreign regulatory agencies, may change, and additional regulations 

may be enacted that could prevent, limit or delay regulatory approval of product candidates. We cannot predict the 
likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive 
action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the 
adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may be subject to 
enforcement action and we may not achieve or sustain profitability. 

Our business operations and future relationships with investigators, healthcare professionals, consultants, third-
party payors, patient organizations and customers will be subject to applicable healthcare regulatory laws, which could 
expose us to penalties.  

Our business operations and future arrangements with investigators, healthcare professionals, consultants, third-party 

payors, patient organizations and customers, may expose us to broadly applicable fraud and abuse and other healthcare 
laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we 
will conduct our operations, including how we research, market, sell and distribute our product candidates, if approved. 
Such laws include:

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from 
knowingly and willfully soliciting, offering, receiving or providing any remuneration (including any 
kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or 
reward, or in return for, either the referral of an individual for, or the purchase, lease, order or 
recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part,

42 

 
  
payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a 
false record or statement material to a false or fraudulent claim, or from knowingly making a false statement 
to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. In addition, the 
government may assert that a claim including items and services resulting from a violation of the U.S. federal 
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;

concealing or covering up a material fact or making any materially false statement, in connection with the 
delivery of, or payment for, healthcare benefits, items or services; similar to the U.S. federal Anti-Kickback 
Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it 
in order to have committed a violation;  

the U.S. federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, 
biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health 
Insurance Program to report annually to the government information related to certain payments and other 
transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and 
chiropractors), certain non-physician practitioners such as physician assistants and nurse practitioners, and 
teaching hospitals, as well as ownership and investment interests held by the physicians described above and 
their immediate family members;  

analogous U.S. state laws and regulations, including: state anti-kickback and false claims laws, which may 
apply to our future business practices, including but not limited to, research, distribution, sales and marketing 
arrangements and claims involving healthcare items or services reimbursed by any third-party payor, 
including private insurers; state laws that require pharmaceutical companies to comply with the 
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance 
promulgated by the U.S. federal government, or otherwise restrict payments that may be made to healthcare 
providers and other potential referral sources; state laws and regulations that require drug manufacturers to 
file reports relating to pricing and marketing information, which requires tracking gifts and other 
remuneration and items of value provided to healthcare professionals and entities; and state laws governing 
the privacy and security of health information in certain circumstances, many of which differ from each other 
in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts; and  

similar healthcare laws and regulations in the EU and other jurisdictions, including reporting requirements 
detailing interactions with and payments to healthcare providers and laws governing the privacy and security 
of certain protected information, such as the General Data Protection Regulation (“GDPR”), which imposes 
obligations and restrictions on the collection and use of personal data relating to individuals located in the 
European Economic Area (“EEA”) (including health data).

Ensuring that our internal operations and future business arrangements with third parties comply with applicable 
healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that 
our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving 
applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of 
the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to 
significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from government-
funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries or jurisdictions, 
disgorgement, individual imprisonment, contractual damages, reputational harm, diminished profits and the curtailment or 
restructuring of our operations.  

The successful commercialization of product candidates developed by us or our partners will depend in part on the 

extent to which governmental authorities and health insurers establish adequate coverage, reimbursement levels and 
pricing policies. Failure to obtain or maintain coverage and adequate reimbursement for such product candidates, if 
approved, could limit our or our partners’ ability to market those products and decrease our ability to generate revenue.  

The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare 

and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to afford 
prescription medications such as our product candidates, assuming FDA approval. Our ability to achieve acceptable levels 
of coverage and reimbursement for products by governmental authorities, private health insurers and other organizations 
will have an effect on our ability to successfully commercialize our product candidates. Assuming we obtain coverage for 
our product candidates by a third-party payor, the resulting reimbursement payment rates may not be adequate or may 

43 

 
require co-payments that patients find unacceptably high. We cannot be sure that coverage and reimbursement in the 
United States, the EU or elsewhere will be available for our product candidates or any product that we may develop, and 
any reimbursement that may become available may be decreased or eliminated in the future.  

Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many 
third-party payors may refuse to provide coverage and reimbursement for particular drugs or biologics when an equivalent 
generic drug, biosimilar or a less expensive therapy is available. It is possible that a third-party payor may consider our 
product candidates as substitutable and only offer to reimburse patients for the less expensive product. Even if we show 
improved efficacy or improved convenience of administration with our product candidates, pricing of existing third-party 
therapeutics may limit the amount we will be able to charge for our product candidates. These payors may deny or revoke 
the reimbursement status of a given product or establish prices for new or existing marketed products at levels that are too 
low to enable us to realize an appropriate return on our investment in our product candidates. For products administered 
under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because 
of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the 
treatment or procedure in which the product is used may not be available, which may impact physician utilization. If 
reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our 
product candidates, and may not be able to obtain a satisfactory financial return on our product candidates.  

No uniform policy for coverage and reimbursement for products exists among third-party payors in the United States. 
Therefore, coverage and reimbursement for products can differ significantly from payor to payor. As a result, the coverage 
determination process is often a time-consuming and costly process that will require us to provide scientific and clinical 
support for the use of our product candidates to each payor separately, with no assurance that coverage and adequate 
reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations regarding 
reimbursement change frequently, in some cases on short notice, and we believe that changes in these rules and regulations 
are likely.  

Outside the United States, international operations are generally subject to extensive governmental price controls and 

other market regulations, and we believe the increasing emphasis on cost-containment initiatives in Europe and other 
countries have and will continue to put pressure on the pricing and usage of our product candidates. In many countries, the 
prices of medical products are subject to varying price control mechanisms as part of national health systems. Other 
countries allow companies to fix their own prices for medical products, but monitor and control company profits. 
Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge 
for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our product 
candidates may be reduced compared with the United States and may be insufficient to generate commercially-reasonable 
revenue and profits.  

Moreover, increasing efforts by governmental and third-party payors in the United States and abroad to cap or reduce 
healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved 
products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to 
experience pricing pressures in connection with the sale of our product candidates due to the trend toward managed health 
care, the increasing influence of health maintenance organizations and additional legislative changes. The downward 
pressure on healthcare costs in general, particularly prescription drugs and biologics and surgical procedures and other 
treatments, has become intense. As a result, increasingly high barriers are being erected to the entry of new products.  

Compliance with European Union chemical regulations could be costly and adversely affect our business and 

results of operations. 

Some of our products are subject to the European Union regulatory regime known as The Registration, Evaluation and 

Authorization of Chemicals (“REACH”). REACH mandates that certain chemicals manufactured in, or imported into, the 
European Union be registered and evaluated for their potential effects on human health and the environment. Under 
REACH, we and our contract manufacturers located in the European Union are required to register certain of our products 
based on the quantity of such product imported into or manufactured in the European Union and on the product’s intended 
end-use. The registration, evaluation and authorization process under REACH can be costly and time consuming. Problems 
or delays in the registration, evaluation or authorization process under REACH could delay or prevent the manufacture of 
some of our products in, or the importation of some of our products into, the European Union, which could adversely affect 
our business and results of operations. In addition, if we or our contract manufacturers fail to comply with REACH, we 
may be subject to penalties or other enforcement actions, which could have a material adverse effect on our business and 
results of operations.

Risks Related to our Dependence on Third Parties 

We rely on third parties to conduct our clinical trials and perform some of our research and preclinical studies. If 

these third parties do not satisfactorily carry out their contractual duties or fail to meet expected deadlines, our 
development programs may be delayed or subject to increased costs, each of which may have an adverse effect on our 
business and prospects. 

We do not have the ability to conduct all aspects of our preclinical testing or clinical trials ourselves. As a result, we 
are and expect to remain dependent on third parties to conduct clinical trials of our product candidates. Specifically, we 
expect CROs, clinical investigators, and consultants to play a significant role in the conduct of these trials and the 
subsequent collection and analysis of data. However, we will not be able to control all aspects of their activities. 
Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with the applicable protocol 
and legal, regulatory and scientific standards, and our reliance on the CROs and other third parties does not relieve us of 
our regulatory responsibilities. We and our CROs are required to comply with GCP requirements, which are regulations 
and guidelines enforced by the FDA and comparable foreign regulatory authorities for all of our product candidates in 
clinical development. Regulatory authorities enforce these GCP requirements through periodic inspections of trial 
sponsors, clinical trial investigators and clinical trial sites. If we or any of our CROs or clinical trial sites fail to comply 
with applicable GCP requirements, the data generated in our clinical trials may be deemed unreliable, and the FDA or 
comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our 
marketing applications. In addition, our clinical trials must be conducted with product produced under cGMP regulations. 
Our failure to comply with these regulations may require us to stop and/or repeat clinical trials, which would delay the 
marketing approval process. 

There is no guarantee that any such CROs, clinical trial investigators or other third parties on which we rely will 
devote adequate time and resources to our development activities or perform as contractually required. If any of these third 
parties fail to meet expected deadlines, adhere to our clinical protocols or meet regulatory requirements, otherwise 
performs in a substandard manner, or terminates its engagement with us, the timelines for our development programs may 
be extended or delayed or our development activities may be suspended or terminated. If any of our clinical trial sites 
terminates for any reason, we may experience the loss of follow-up information on subjects enrolled in such clinical trials 
unless we are able to transfer those subjects to another qualified clinical trial site, which may be difficult or impossible. In 
addition, clinical trial investigators for our clinical trials may serve as scientific advisors or consultants to us from time to 
time and may receive cash or equity compensation in connection with such services. If these relationships and any related 
compensation result in perceived or actual conflicts of interest, or the FDA or comparable foreign regulatory authorities 
concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated 
at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which 
could result in the delay or rejection of any marketing application we submit by the FDA or any comparable foreign 
regulatory authority. Any such delay or rejection could prevent us from commercializing our product candidates. 

We contract with third parties for the manufacturing and supply of product candidates for use in preclinical testing 

and clinical trials and related services, which supply may become limited or interrupted or may not be of satisfactory 
quality and quantity. 

We do not have any manufacturing facilities. We produce in our laboratory relatively small quantities of products for 

evaluation in our research programs. We rely, and expect to continue to rely, on third parties for the manufacture of our 
product candidates for preclinical and clinical testing, as well as for commercial manufacture if any of our product 
candidates are approved. We currently have limited manufacturing arrangements and expect that each of our product 
candidates will only be covered by single source suppliers for the foreseeable future. This reliance increases the risk that 
we will not have sufficient quantities of our product candidates or products, if approved, or such quantities at an acceptable 
cost or quality, which could delay, prevent or impair our development or commercialization efforts. 

Furthermore, all entities involved in the preparation of therapeutics for clinical trials or commercial sale, including our 

existing contract manufacturers for our product candidates, are subject to extensive regulation. Components of a finished 
therapeutic product approved for commercial sale or used in clinical trials must be manufactured in accordance with cGMP 
requirements. These regulations govern manufacturing processes and procedures, including record keeping, and the 
implementation and operation of quality systems to control and assure the quality of investigational products and products 
approved for sale. Poor control of production processes can lead to the introduction of contaminants, or to inadvertent 
changes in the properties or stability of our product candidates that may not be detectable in final product testing. We or our 
contract manufacturers must supply all necessary documentation in support of a BLA on a timely basis and must adhere to 
the FDA’s cGMP regulations enforced by the FDA through its facilities inspection program. Comparable foreign regulatory 

45 

 
authorities may require compliance with similar requirements. The facilities and quality systems of our third-party 
contractor manufacturers must pass a pre-approval inspection for compliance with the applicable regulations as a condition 
of marketing approval of our product candidates. We do not control the manufacturing activities of, and are completely 
dependent on, our contract manufacturers for compliance with cGMP regulations. 

In the event that any of our manufacturers fails to comply with such requirements or to perform its obligations to us in 

relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted 
for other reasons, we may be forced to manufacture the materials ourselves, for which we currently do not have the 
capabilities or resources, or enter into an agreement with another third party, which we may not be able to do on 
commercially reasonable terms, if at all. In particular, any replacement of our manufacturers could require significant effort 
and expertise because there may be a limited number of qualified replacements. In some cases, the technical skills or 
technology required to manufacture our product candidates may be unique or proprietary to the original manufacturer and 
we may have difficulty transferring such skills or technology to another third party and a feasible alternative may not exist. 
In addition, certain of our product candidates and our own proprietary methods have never been produced or implemented 
outside of our company, and we may therefore experience delays to our development programs if and when we attempt to 
establish new third party manufacturing arrangements for these product candidates or methods. These factors would 
increase our reliance on such manufacturer or require us to obtain a license from such manufacturer in order to have 
another third party manufacture our product candidates. If we are required to change manufacturers for any reason, we will 
be required to verify that the new manufacturer maintains facilities and procedures that comply with quality standards and 
with all applicable regulations and guidelines. The delays associated with the verification of a new manufacturer could 
negatively affect our ability to develop product candidates in a timely manner or within budget.  

Our or a third party’s failure to execute on our manufacturing requirements, do so on commercially reasonable terms 

and comply with cGMP could adversely affect our business in a number of ways, including: 

▪ 

▪ 

▪ 

▪ 

▪ 

▪ 

an inability to initiate or continue clinical trials of our product candidates under development; 

delay in submitting regulatory applications, or receiving marketing approvals, for our product candidates; 

loss of the cooperation of future collaborators; 

subjecting third-party manufacturing facilities or our manufacturing facilities to additional inspections by 
regulatory authorities; 

requirements to cease development or to recall batches of our product candidates; and 

in the event of approval to market and commercialize our product candidates, an inability to meet commercial 
demands for our product or any other future product candidates. 

Risks Related to Intellectual Property and Information Technology 

Our efforts to prosecute and protect our intellectual property may not be successful. 

We will continue to file and prosecute patent applications and maintain trade secrets in an ongoing effort to protect our 

intellectual property. It is possible that our current patents, or patents which we may later acquire, may be successfully 
challenged or invalidated in whole or in part. It is also possible that we may not obtain issued patents from our pending 
patent applications or other inventions we seek to protect. We sometimes permit certain patents or patent applications to 
lapse or go abandoned under appropriate circumstances. Due to uncertainties inherent in prosecuting patent applications, 
sometimes patent applications are rejected, and we subsequently abandon them. It is also possible that we may develop 
proprietary products or technologies in the future that are not patentable or that the patents of others will limit or altogether 
preclude our ability to conduct business. In addition, any patent issued to us or to our licensor may provide us with little or 
no competitive advantage, in which case we may abandon such patent or license it to another entity, or terminate the 
license agreement. 

Our means of protecting our proprietary rights may not be adequate and our competitors may independently develop 
technology or products that are similar to ours or that compete with ours. Patent, trademark, copyright and trade secret laws 
afford only limited protection for our technology platform, services and products. The laws of many countries do not 
protect our proprietary rights to as great an extent as do the laws of the United States. Despite our efforts to protect our 
proprietary rights, unauthorized parties have in the past attempted, and may in the future attempt, to operate under aspects 
of our intellectual property, technology, services or products or to obtain and use information that we regard as proprietary. 
Third parties may also design around our proprietary rights, which may render our protected technology, services and 
products less valuable, if the design around is favorably received in the marketplace. In addition, if any of our products, 
services or technology is covered by third-party patents or other intellectual property rights, we could be subject to various 

46 

 
legal actions. We cannot assure you that our technology platform, services and products do not infringe patents held by 
others or that they will not in the future.  

Litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, to determine the 

validity and scope of the proprietary rights of others, or to defend against claims of infringement, invalidity, 
misappropriation, or other claims.  

Any such litigation could result in substantial costs and diversion of our resources. Moreover, any settlement of or 
adverse judgment resulting from litigation relating to intellectual property could require us to obtain a license to continue to 
make, use or sell the products or technology that is the subject of the claim, or otherwise restrict or prohibit our use of the 
technology, product or services. 

Our ability to compete may decline if we do not adequately protect our proprietary technologies or if we lose some 

of our intellectual property rights.  

Our success depends in part on our ability to obtain patents and maintain adequate protection of our intellectual 

property for our technologies, services and products in the United States and other countries. We have adopted a strategy of 
seeking patent protection in the United States and in foreign countries with respect to certain of the technologies used in or 
relating to our services, products and processes. As such, as of December 31, 2021, we owned or controlled approximately 
1,900 issued patents and pending patent applications in the United States and in various foreign jurisdictions. Our patents 
and patent applications, if issued, as of December 31, 2021, have terms that expire between 2022 and approximately 2042. 
We also have license rights to a number of issued patents and pending patent applications in the United States and in 
various foreign jurisdictions. Our owned and licensed patents and patent applications include those directed to our enabling 
technologies and to the methods and products that support our business in the biotherapeutics, molecular diagnostics, food 
and other markets. We intend to continue to apply for patents relating to our technologies, methods, services and products 
as we deem appropriate.  

Issuance of claims in patent applications and enforceability of such claims once issued involve complex legal and 

factual questions and, therefore, we cannot predict with any certainty whether any of our issued patents will survive 
invalidity claims asserted by third parties. Issued patents and patents issuing from pending applications may be challenged, 
invalidated, or circumvented. Moreover, the United States Leahy-Smith America Invents Act (“AIA”), enacted in 
September 2011, brought significant changes to the United States patent system, which include a change to a “first to file” 
system from a “first to invent” system and changes to the procedures for challenging issued patents and disputing patent 
applications during the examination process, among other things. While interference proceedings are possible for patent 
claims filed prior to March 16, 2013, many of our filings will be subject to the post- and pre-grant proceedings set forth in 
the AIA, including citation of prior art and written statements by third parties, third party pre-issuance submissions, ex 
parte reexamination, inter partes review, post-grant review, and derivation proceedings. We may need to utilize the 
processes provided by the AIA for supplemental examination or patent reissuance. These proceedings could result in 
substantial cost to us even if the outcome is favorable. Even if successful, any interference may result in loss of certain 
claims. Any litigation or proceedings could divert our management's time and efforts. Even unsuccessful claims brought by 
third parties could result in significant legal fees and other expenses, diversion of management time, and disruption in our 
business. Uncertainties resulting from initiation and continuation of any patent or related litigation could harm our ability 
to compete. We have not assessed the applicability of the AIA and new regulations on our patent portfolio. These changes 
could increase the costs and uncertainties surrounding the prosecution of our patent applications and the enforcement or 
defense of our patent rights. 

Additional uncertainty may result from legal precedent handed down by the United States Federal Circuit Court and 

Supreme Court as they determine legal issues concerning the scope and construction of patent claims and inconsistent 
interpretation of patent laws by the lower courts. Accordingly, we cannot ensure that any of our pending patent applications 
will result in issued patents, or even if issued, predict the breadth of the claims upheld in our and other companies' patents. 
Given that the degree of future protection for our proprietary rights is uncertain, we cannot ensure that: (i) we were the first 
to invent the inventions covered by each of our pending applications, (ii) we were the first to file patent applications for 
these inventions, or (iii) the proprietary technologies we develop will be patentable. In addition, unauthorized parties may 
attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our intellectual 
property is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, 
particularly in certain foreign countries where the local laws may not protect our proprietary rights as fully as in the United 
States. Moreover, third parties could practice our inventions in territories where we do not have patent protection. Such 
third parties may then try to import products made using our inventions into the United States or other countries. If 
competitors are able to use our technology, our ability to compete effectively could be harmed. In addition, others may 
independently develop and obtain patents for technologies that are similar to or superior to our technologies. If that 

47 

 
happens, we may need to license these technologies, and we may not be able to obtain licenses on reasonable terms, if at 
all, which could cause harm to our business. 

Third parties may claim that we are infringing their intellectual property rights or other proprietary rights, which 

may subject us to costly and time consuming litigation and prevent us from developing or commercializing our 
products.  

Our commercial success also depends in part on our ability to operate without infringing patents and proprietary rights 

of third parties, and without breaching any licenses or other agreements that we have entered into with regard to our 
technologies, services, products and business. We cannot ensure that patents have not been issued to third parties that could 
block our ability to obtain patents or to operate as we would like. There may be patents in some countries that, if valid, may 
block our ability to make, use or sell our products in those countries, or import our products into those countries, if we are 
unsuccessful in circumventing or acquiring rights to these patents. There also may be claims in patent applications filed in 
some countries that, if granted and valid, may also block our ability to commercialize products or processes in these 
countries if we are unable to circumvent or license them.  

The industries in which we operate and the biotechnology industry, in particular, are characterized by frequent and 
extensive litigation regarding patents and other intellectual property rights. Many biotechnology companies have employed 
intellectual property litigation as a way to gain a competitive advantage. Our involvement in litigation or other intellectual 
property proceedings inside and outside of the United States, to defend our intellectual property rights or as a result of 
alleged infringement of the rights of others, may divert our management’s time from focusing on business operations and 
could cause us to spend significant amounts of money. Any potential intellectual property litigation also could force us to 
do one or more of the following:  

• 

• 

• 

• 

• 

stop selling or using our products or technologies that use the subject intellectual property;  

pay monetary damages or substantial royalties;  

grant cross-licenses to third parties relating to our patents or proprietary rights;  

obtain from the third party asserting its intellectual property rights a license to sell or use the relevant 
technology, which license may not be available on reasonable terms, or at all; or  

redesign those products or processes that use any allegedly infringing technology, or relocate the operations 
relating to the allegedly infringing technology to another jurisdiction, which may result in significant cost or 
delay to us, could be technically infeasible or could prevent us from selling some of our products in the 
United States or other jurisdictions.  

We are aware of some patents and patent applications relating to aspects of our technologies filed by, and issued to, 

third parties. We cannot assure you that if this third party intellectual property is asserted against us that we would 
ultimately prevail. 

We may be involved in lawsuits to protect or enforce our intellectual property rights, which could be expensive, 

time-consuming and unsuccessful.  

Competitors may infringe our intellectual property rights or those of our licensors. To prevent infringement or 
unauthorized use, we have in the past filed, and may in the future be required to file, infringement claims, which can be 
expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that the intellectual 
property that we own or in-license is not valid, is unenforceable and/or is not infringed. In addition, in legal proceedings 
against a third party to enforce a patent directed at one of our technologies, services or products, the defendant could 
counterclaim that our patent is invalid and/or unenforceable in whole or in part. In patent litigation in the United States, 
defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a patent validity 
challenge include an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or 
non-enablement. Grounds for an unenforceability assertion could include an allegation that someone connected with 
prosecution of the patent withheld relevant information from the United States Patent and Trademark Office (“USPTO”) or 
made a misleading statement during prosecution. Third parties may also raise similar claims before the USPTO, even 
outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable, 
and prior art could render our patents or those of our licensors invalid. If a defendant were to prevail on a legal assertion of 
invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on such product. 
Such a loss of patent protection would have a material adverse impact on our business.  

Even if resolved in our favor, litigation or other legal proceedings relating to our intellectual property rights may cause 

us to incur significant expenses, and could distract our technical and management personnel from their normal 

48 

 
responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim 
proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a 
substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our 
expenses and reduce the resources available for operations and research and development activities. We may not have 
sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may 
be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial 
resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could 
compromise our ability to compete in the marketplace. Furthermore, because of the substantial amount of discovery 
required in connection with intellectual property litigation, there is a risk that some of our confidential information could 
be compromised by disclosure during this type of litigation.  

We may not be able to enforce our intellectual property rights throughout the world. 

The laws of some foreign countries where we do business do not protect intellectual property rights to the same extent 

as the laws of the United States. Many companies have encountered significant problems in protecting and defending 
intellectual property rights in certain foreign jurisdictions. The legal systems of certain countries, particularly certain 
developing countries, do not favor the enforcement of patents and other intellectual property, particularly those relating to 
biotechnology and/or bioindustrial technologies. Accordingly, our efforts to protect our intellectual property rights in such 
countries may be inadequate. This could make it difficult for us to stop the infringement of our patents or misappropriation 
of our other intellectual property rights. Additionally, proceedings to enforce our patent rights in foreign jurisdictions could 
result in substantial costs and divert our efforts and attention from other aspects of our business. 

If our biocatalysts, or the genes that code for our biocatalysts, are stolen, misappropriated or reverse engineered, 

others could use these biocatalysts or genes to produce competing products.  

Third parties, including our contract manufacturers, customers and those involved in shipping our biocatalysts, often 

have custody or control of our biocatalysts. If our biocatalysts, or the genes that code for our biocatalysts, were stolen, 
misappropriated or reverse engineered, they could be used by other parties who may be able to reproduce these biocatalysts 
for their own commercial gain. If this were to occur, it may be difficult for us to challenge this type of use, especially in 
countries with limited intellectual property protection or in countries in which we do not have patents covering the 
misappropriated biocatalysts. 

Risks Related to Owning our Common Stock  

We are subject to anti-takeover provisions in our certificate of incorporation and bylaws and under Delaware law 

that could delay or prevent an acquisition of our company, even if the acquisition would be beneficial to our 
stockholders.  

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition 

of us. Among other things, our amended and restated certificate of incorporation and bylaws provide for a board of 
directors which is divided into three classes, with staggered three-year terms and provide that all stockholder action must 
be effected at a duly called meeting of the stockholders and not by a consent in writing, and further provide that only our 
board of directors, the chairman of the board of directors, our chief executive officer or president may call a special 
meeting of the stockholders. In addition, our amended and restated certificate of incorporation allows our board of 
directors, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock in one or more 
series and to fix the rights, preferences, privileges and restrictions thereof. These provisions may also frustrate or prevent 
any attempts by our stockholders to replace or remove our current management by making it more difficult for 
stockholders to replace members of our board of directors, who are responsible for appointing the members of our 
management team. Furthermore, because we are incorporated in Delaware, we are governed by the provisions of 
Section 203 of the Delaware General Corporation Law which prohibits, with some exceptions, stockholders owning in 
excess of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents 
establish advanced notice requirements for nominations for election to our board of directors and for proposing matters that 
can be acted upon at stockholder meetings. Although we believe these provisions together provide for an opportunity to 
receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if an 
offer to acquire our company may be considered beneficial by some stockholders.

Our quarterly or annual operating results may fluctuate in the future. As a result, we may fail to meet or exceed the 

expectations of research analysts or investors, which could cause our stock price to decline.  

Our financial condition and operating results have varied significantly in the past and may continue to fluctuate from 
quarter to quarter and year to year in the future due to a variety of factors, many of which are beyond our control. Factors 
relating to our business that may contribute to these fluctuations include the following factors, as well as other factors 
described elsewhere in this report:

Due to the various factors mentioned above, and others, the results of any prior quarterly or annual periods should not 

be relied upon as indications of our future operating performance. 

We do not intend to pay cash dividends for the foreseeable future. 

We currently intend to retain our future earnings, if any, to finance the further development and expansion of our 
business and do not intend to pay cash dividends in the foreseeable future. Any future determination to pay dividends will 
be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital 
requirements, restrictions contained in future agreements and financing instruments, business prospects and such other 
factors as our board of directors deems relevant. 

General Risk Factors 

If securities or industry analysts do not publish research or reports about our business, or publish negative reports 

about our business, our stock price and trading volume could decline.  

The trading market for our common stock will be influenced by the research and reports that securities or industry 
analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts 
who cover us downgrade our stock or change their opinion of our stock in a negative manner, our stock price would likely 
decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could 
lose visibility in the financial markets, which could cause our stock price or trading volume to decline. 

51 

 
 
We face risks associated with our international business.  

While we have a limited number of employees located outside of the United States, we are and will continue to be 
dependent upon contract manufacturers located outside of the United States. In addition, we have customers and partners 
located outside of the United States. Conducting business internationally exposes us to a variety of risks, including: 

• 

• 
• 

• 

• 
• 

• 

• 

• 
• 
• 

changes in or interpretations of foreign regulations that may adversely affect our ability to sell our products, 
repatriate profits to the United States or operate our foreign-located facilities;  
the imposition of tariffs;  
the imposition of limitations on, or increase of, withholding and other taxes on remittances and other payments by 
foreign subsidiaries or joint ventures;  
the imposition of limitations on genetically-engineered products or processes and the production or sale of those 
products or processes in foreign countries;  
currency exchange rate fluctuations;  
uncertainties relating to foreign laws, regulations and legal proceedings including tax, import/export, anti-
corruption and exchange control laws;  
the availability of government subsidies or other incentives that benefit competitors in their local markets that are 
not available to us;  
increased demands on our limited resources created by our operations may constrain the capabilities of our 
administrative and operational resources and restrict our ability to attract, train, manage and retain qualified 
management, technicians, scientists and other personnel;  
economic or political instability in foreign countries;  
difficulties associated with staffing and managing foreign operations; and  
the need to comply with a variety of United States and foreign laws applicable to the conduct of international 
business, including import and export control laws and anti-corruption laws.  

Business interruptions resulting from disasters or other disturbances could delay us in the process of developing 

our products and could disrupt our sales. Our business continuity and disaster recovery plans may not adequately 
protect us from a serious disaster or other disturbance. 

Our headquarters and other facilities are located in the San Francisco Bay Area, which in the past has experienced both 

severe earthquakes and wildfires. Earthquakes, wildfires or other natural disasters could severely disrupt our operations, 
and have a material adverse effect on our business, results of operations, financial condition and prospects. We are also 
vulnerable to other types of disasters and other events that could disrupt our operations, such as riot, civil disturbances, 
war, terrorist acts, infections in our laboratory or production facilities or those of our customers or contract manufacturers 
and other events beyond our control. If a natural disaster or other event occurred that prevented us from using all or a 
significant portion of our headquarters, that damaged critical infrastructure, such as our enterprise financial systems or 
manufacturing resource planning and enterprise quality systems, or that otherwise disrupted operations, it may be difficult 
or, in certain cases, impossible, for us to continue our business for a substantial period of time. The disaster recovery and 
business continuity plans we have in place currently are limited and are unlikely to prove adequate in the event of a serious 
disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and 
business continuity plans. We do not carry insurance for earthquakes and we may not carry sufficient business interruption 
insurance to compensate us for losses that may occur. Any losses or damages we incur could have a material adverse effect 
on our cash flows and success as an overall business. 

Confidentiality agreements with employees and others may not adequately prevent disclosures of trade secrets and 

other proprietary information.  

We rely in part on trade secret and confidentiality protection to protect our confidential and proprietary information 

and processes. However, trade secrets and confidential information are difficult to protect. We have taken measures to 
protect our trade secrets and confidential and proprietary information, but these measures may not be effective. We require 
employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting 
arrangement with us. These agreements generally require that all confidential information developed by the individual or 
made known to the individual by us during the course of the individual’s relationship with us be kept confidential and not 
disclosed to third parties. These agreements also generally provide that inventions conceived by the individual in the course 
of rendering services to us shall be our exclusive property. Nevertheless, our confidential and proprietary information may 
be disclosed, third parties could reverse engineer our biocatalysts and others may independently develop substantially 

52 

 
 
 
 
 
 
equivalent confidential and proprietary information and techniques or otherwise gain access to our trade secrets. Costly and 
time-consuming litigation could be necessary to enforce and determine the scope of our confidential and proprietary rights, 
and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.  

We are dependent on information technology systems, infrastructure and data, and any failure of these systems 
could harm our business. Security breaches, loss of data, and other disruptions could compromise sensitive information 
related to our business or prevent us from accessing critical information and expose us to liability, which could 
adversely affect our business, results of operations and financial condition. 

Information technology helps us operate efficiently, interface with customers, maintain financial accuracy and 
efficiency, and accurately produce our financial statements. If we do not allocate and effectively manage the resources 
necessary to build and sustain the proper technology infrastructure, we could be subject to transaction errors, processing 
inefficiencies, the loss of customers, business disruptions, or the loss of or damage to intellectual property through security 
breach. If our data management systems do not effectively collect, store, process, and report relevant data for the operation 
of our business, whether due to equipment malfunction or constraints, software deficiencies, or human error, our ability to 
effectively plan, forecast, and execute our business plan and comply with applicable laws and regulations will be impaired, 
perhaps materially. Any such impairment could materially and adversely affect our financial condition, results of 
operations, cash flows, and the timeliness with which we report our internal and external operating results. 

Our business may require us to use and store personal information of our customers, employees, and business partners. 

This may include names, addresses, phone numbers, email addresses, contact preferences, tax identification numbers, and 
payment account information. We require usernames and passwords in order to access our information technology systems. 
We also use encryption and authentication technologies to secure the transmission and storage of data. However, these 
security measures may be compromised as a result of security breaches by unauthorized persons, employee error, 
malfeasance, faulty password management, or other irregularity, and result in persons obtaining unauthorized access to our 
data or accounts. Third parties may attempt to fraudulently induce employees or customers into disclosing usernames, 
passwords, or other sensitive information, which may in turn be used to access our information technology systems. For 
example, our employees have received “phishing” emails and phone calls attempting to induce them to divulge passwords 
and other sensitive information. 

In addition, unauthorized persons may attempt to hack into our products or systems to obtain personal data relating to 
employees and other individuals, our confidential or proprietary information or confidential information we hold on behalf 
of third parties. We also rely on external vendors to supply and/or support certain aspects of our information technology 
systems. The systems of these external vendors may contain defects in design or manufacture or other problems that could 
unexpectedly compromise information security of our own systems, and we are dependent on these third parties to deploy 
appropriate security programs to protect their systems. If we or our third-party vendors were to experience a significant 
cybersecurity breach of our or their information systems or data, the costs associated with the investigation, remediation 
and potential notification of the breach to counter-parties and data subjects could be material. Our remediation efforts may 
not be successful. Further, if such an event were to occur and cause interruptions in our operations, it could result in a 
material disruption of our development programs and our business operations, whether due to a loss, corruption or 
unauthorized disclosure of our trade secrets, personal information or other proprietary or sensitive information or other 
similar disruptions. Attacks upon information technology systems are also increasing in their frequency, levels of 
persistence, sophistication and intensity, and are being conducted by sophisticated and organized groups and individuals 
with a wide range of motives and expertise. As a result of the COVID-19 pandemic, we may also face increased 
cybersecurity risks due to our reliance on internet technology and the number of our employees who are working remotely, 
which may create additional opportunities for cybercriminals to exploit vulnerabilities. We have programs in place to 
detect, contain, and respond to data security incidents, and we make ongoing improvements to our information-sharing 
products in order to minimize vulnerabilities, in accordance with industry and regulatory standards. However, because the 
techniques used to obtain unauthorized access to or sabotage systems change frequently and may be difficult to detect, we 
may not be able to anticipate and prevent these intrusions or mitigate them when and if they occur. 

If a security breach or other incident were to result in the unauthorized access to or unauthorized use, disclosure, 
release or other processing of personal information, it may be necessary to notify individuals, governmental authorities, 
supervisory bodies, the media and other parties pursuant to privacy and security laws. Any security compromise affecting 
us, our service providers, vendors, strategic partners, other contractors, consultants, or our industry, whether real or 
perceived, could harm our reputation, erode confidence in the effectiveness of our security measures and lead to regulatory 
scrutiny. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or systems, 
or inappropriate disclosure of confidential or proprietary or personal information, we could incur liability, including 

53 

 
 
 
 
 
litigation exposure, penalties and fines, we could become the subject of regulatory action or investigation, our competitive 
position could be harmed and the further development of our products could be delayed. If such an event were to occur and 
cause interruptions in our operations, it could result in a material disruption of our business. Furthermore, federal, state and 
international laws and regulations can expose us to enforcement actions and investigations by regulatory authorities, and 
potentially result in regulatory penalties, fines and significant legal liability, if our information technology security efforts 
fail. We may also be exposed to a risk of loss or litigation and potential liability, which could materially and adversely 
affect our business, results of operations and financial condition. 

Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, 
standards and other requirements could adversely affect our business, results of operations, and financial condition. 

The global data protection landscape is rapidly evolving, and we are or may become subject to state, federal and 
foreign laws, regulations, decisions, and directives governing the privacy, security, collection, storage, transmission, use, 
processing, retention and disclosure of personal information. Any failure or perceived failure by us to comply with 
applicable laws or regulations, our internal policies and procedures or our contracts governing our processing of personal 
information could result in negative publicity, government investigations and enforcement actions, claims by third parties 
and damage to our reputation, any of which could have a material adverse effect on our operations, financial performance 
and business. 

In the United States, HIPAA imposes, among other things, certain standards relating to the privacy, security, 

transmission and breach reporting of individually identifiable health information. Certain states have also adopted 
comparable privacy and security laws and regulations, some of which may be more stringent than HIPAA. Such laws and 
regulations will be subject to interpretation by various courts and other governmental authorities, thus creating potentially 
complex compliance issues for us and our future customers and strategic partners. For example, the CCPA went into effect 
on January 1, 2020 , and introduces new compliance burdens on organizations doing business in California that collect 
personal information about California residents. It creates individual privacy rights for California consumers and increases 
the privacy and security obligations of entities handling certain personal information. The CCPA also provides for civil 
penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach 
litigation. Further, the CPRA recently passed in California. The CPRA will impose additional data protection obligations on 
covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for 
higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency 
authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The 
majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential 
business process changes may be required. Similar laws have passed in Virginia and Colorado, and have been proposed in 
other states and at the federal level, reflecting a trend toward more stringent privacy legislation in the United States.  These 
developments increase our compliance burden and our risk, including risks of regulatory fines, litigation and associated 
reputational harm. Any liability from failure to comply with the requirements of these laws could adversely affect our 
financial condition.  

Furthermore, the Federal Trade Commission (“FTC”) and many state Attorneys General continue to enforce federal 
and state consumer protection laws against companies for online collection, use, dissemination and security practices that 
appear to be unfair or deceptive. For example, according to the FTC, failing to take appropriate steps to keep consumers’ 
personal information secure can constitute unfair acts or practices in or affecting commerce in violation of Section 5(a) of 
the Federal Trade Commission Act. The FTC expects a company’s data security measures to be reasonable and appropriate 
in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost 
of available tools to improve security and reduce vulnerabilities. 

In Europe, the GDPR went into effect in May 2018 and imposes strict requirements for processing the personal data of 
individuals within the EEA. The GDPR imposes stringent requirements for controllers and processors of personal data and 
increases our obligations, for example, by imposing higher standards when obtaining consent from individuals to process 
their personal data, requiring more robust disclosures to individuals, strengthening individual data rights, shortening 
timelines for data breach notifications, limiting retention periods and secondary use of information, increasing 
requirements pertaining to health data as well as pseudonymized (i.e., key-coded) data, and imposing additional obligations 
when we contract with third-party processors in connection with the processing of personal data. The GDPR provides that 
EEA member states may make their own additional laws and regulations limiting the processing of genetic, biometric, or 
health data, which could limit our ability to use and share personal data or could cause our costs to increase and harm our 
business and financial condition. Failure to comply with the requirements of the GDPR can result in fines of up to the 
greater of €20 million and 4% of the total worldwide annual turnover of the preceding financial year and other 
administrative penalties. If we are required to comply with the new data protection rules imposed by GDPR, such 

54 

 
 
 
 
 
compliance may be onerous and adversely affect our business, financial condition, and results of operations. Among other 
requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that have not been 
found to provide adequate protection to such personal data, including the United States, and the efficacy and longevity of 
current transfer mechanisms between the EU and the United States remains uncertain. For example, in July 2020, the Court 
of Justice of the EU (“CJEU”) limited how organizations could lawfully transfer personal data from the EU/EEA to the 
United States by invalidating the Privacy Shield for purposes of international transfers and imposing further restrictions on 
the use of standard contractual clauses (“SCCs”). The European Commission issued revised SCCs on June 4, 2021 to 
account for the decision of the CJEU and recommendations made by the European Data Protection Board. The revised 
SCCs must be used for relevant new data transfers from September 27, 2021; existing standard contractual clauses 
arrangements must be migrated to the revised clauses by December 27, 2022. The new SCCs apply only to the transfer of 
personal data outside of the EEA and not the United Kingdom; the United Kingdom’s Information Commissioner’s Office 
launched a public consultation on its draft revised data transfers mechanisms in August 2021. There is some uncertainty 
around whether the revised clauses can be used for all types of data transfers, particularly whether they can be relied on for 
data transfers to non-EEA entities subject to the GDPR. As supervisory authorities issue further guidance on personal data 
export mechanisms, including circumstances where the SCCs cannot be used, and/or start taking enforcement action, we 
could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to 
transfer personal data between and among countries and regions in which we operate, it could affect the manner in which 
we provide our services, the geographical location or segregation of our relevant systems and operations, and could 
adversely affect our financial results. 

Further, from January 1, 2021, companies have had to comply with the GDPR and also the United Kingdom GDPR 
(“UK GDPR”), which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The 
UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (or up to £17.5 million for UK) or 
4% of global turnover. The relationship between the United Kingdom and the European Union in relation to certain aspects 
of data protection law remains unclear, and it is unclear how United Kingdom data protection laws and regulations will 
develop in the medium to longer term. The European Commission has adopted an adequacy decision in favor of the United 
Kingdom, enabling data transfers from EU member states to the United Kingdom without additional safeguards. However, 
the UK adequacy decision will automatically expire in June 2025 unless the European Commission re-assesses and renews 
or extends that decision. 

Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other 
legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner 
from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. 
Various federal, state and foreign legislative or regulatory bodies may enact new or additional laws and regulations 
concerning privacy, data-retention and data-protection issues, including laws or regulations mandating disclosure to 
domestic or international law enforcement bodies, which could adversely impact our business or our reputation with 
customers. For example, some countries have adopted laws mandating that certain personal information regarding 
customers in their country be maintained solely in their country. Having to maintain local data centers and redesign 
product, service and business operations to limit Personal Information processing to within individual countries could 
increase our operating costs significantly. Any failure, or perceived failure, by us to comply with federal, state or 
international privacy, data-retention or data-protection-related laws, regulations, orders or industry self-regulatory 
principles could result in proceedings or actions against us by governmental entities or others, a loss of customer 
confidence, damage to our brand and reputation and a loss of customers, any of which could have an adverse effect on our 
business. 

Evolving expectations around corporate responsibility practices, specifically related to environmental, social and 

governance (“ESG”) matters, may expose us to reputational and other risks. 

Investors, stockholders, customers, suppliers and other third parties are increasingly focusing on ESG and corporate 

social responsibility endeavors and reporting. Companies that do not adapt to or comply with the evolving investor or 
stakeholder expectations and standards, or which are perceived to have not responded appropriately, may suffer from 
reputational damage and result in the business, financial condition and/or stock price of a company being materially and 
adversely affected. Further, this increased focus on ESG issues may result in new regulations and/or third-party 
requirements that could adversely impact our business, or certain shareholders reducing or eliminating their holdings of our 
stock. Additionally, an allegation or perception that we have not taken sufficient action in these areas could negatively 
harm our reputation.

ITEM 1B. UNRESOLVED STAFF COMMENTS 

ITEM 2. PROPERTIES 

Our headquarters are located in Redwood City, California, where we lease approximately 77,300 square feet of office and 

laboratory space. 

Our lease (“RWC Lease”) with Metropolitan Life Insurance Company (“MetLife”) includes approximately 28,200 square 
feet  of  space  located  at  200  and  220  Penobscot  Drive,  Redwood  City,  California  (the  “200/220  Penobscot  Space”), 
approximately  37,900  square  feet  of  space  located  at  400  Penobscot  Drive,  Redwood  City,  California  (the  “400  Penobscot 
Space”) (the 200/220 Penobscot Space and the 400 Penobscot Space are collectively referred to as the “Penobscot Space”), and 
approximately  11,200  square  feet  of  space  located  at  501  Chesapeake  Drive,  Redwood  City,  California  (the  “Chesapeake 
Space”).  

We  entered  into  the  initial  lease  with  MetLife  for  our  facilities  in  Redwood  City  in  2004  and  the  RWC  lease  has  been 
amended multiple times since then to adjust the leased space and terms of the RWC Lease. In February 2019, we entered into 
an Eighth Amendment to the RWC Lease (the “Eighth Amendment”) with MetLife with respect to the Penobscot Space and the 
501 Chesapeake Space  to  extend  the  term of  the  RWC Lease for additional periods. Pursuant  to the Eighth Amendment, the 
term of the lease of the Penobscot Space has been extended through May 2027. The lease term for the 501 Chesapeake Space 
has been extended to May 2029. We have one (1) option to extend the term of the lease for the Penobscot Space for five (5) 
years, and one (1) separate option to extend the term of the lease for the 501 Chesapeake Space for five (5) years. 

In January 2021, we entered into a lease agreement with ARE-San Francisco No. 63, LLC (“ARE”) to lease a portion of a 
facility  comprising  approximately  36,593  rentable  square  feet  at  825  Industrial  Road,  San  Carlos,  California  to  serve  as 
additional office and research and development laboratory space (the “San Carlos Space”). In December 2021, we commenced 
occupancy of the San Carlos Space. The lease term for the San Carlos Space is through the end of November 2031. We have 
one (1) option to extend the term of the lease for the San Carlos Space for five (5) years. 

In  May  2021,  we  entered  into  a  short-term  office  lease  with  The  Inside  Source,  Inc.,  to  sublease  approximately  3,313 
square feet of office space in a building located at 985 Industrial Blvd.. San Carlos, California. This lease will expire in April 
2022. 

We believe that the facilities that we currently lease in Redwood City and San Carlos, California are adequate for our needs 

for the immediate future and that, should it be needed, additional space can be leased to accommodate any future growth.

Our common stock is quoted on the Nasdaq Global Select Market (“Nasdaq”), under the symbol “CDXS.”  

As of February 24, 2022, there were approximately 129 stockholders of record. A substantially greater number of 

stockholders may be “street name” or beneficial holders, whose shares are held of record by banks, brokers and other financial 
institutions. 

Dividend Policy 

We have never declared or paid cash dividends on our common stock, and we currently do not plan to declare dividends on 

shares of our common stock in the foreseeable future. We expect to retain our future earnings, if any, for use in the operation 
and expansion of our business. In addition, unless waived, the terms of our Credit Facility prohibit us from paying any cash 
dividends or making other distributions. The payment of cash dividends in the future, if any, will be at the discretion of our 
board of directors and will depend upon such factors as earnings levels, capital requirements, our overall financial condition 
and any other factors deemed relevant by our board of directors. 

Securities Authorized for Issuance under Equity Compensation Plans 

The information required by this item concerning securities authorized for issuance under equity compensation plans is 

incorporated by reference from the information that will be set forth in the Definitive Proxy Statement to be filed with the 
Securities and Exchange Commission in connection with the Annual Meeting of Stockholders to be held in 2022 (the “2022 
Proxy Statement”) under the heading “Executive Compensation—Equity Compensation Plan Information.”  

Stock Price Performance Graph 

The following tabular information and graph compare our total common stock return with the total return for (i) the Nasdaq 

Composite Index and (ii) the Nasdaq Biotechnology Index for the period December 31, 2016 through December 31, 2021. The

Business Overview 

We discover, develop and sell enzymes and other proteins that deliver value to our clients in a growing set of industries. We 

view proteins as a vast, largely untapped source of value-creating products, and we are using our proven technologies, which 
we have been continuously improving since our inception in 2002, to commercialize an increasing number of novel enzymes, 
both as proprietary Codexis products and in partnership with our customers. 

We are a pioneer in harnessing computational technologies to drive biology advancements. Since 2002, we have made 
substantial investments in the development of our CodeEvolver® protein engineering technology platform, the primary source 
of our competitive advantage. Our technology platform is powered by proprietary, artificial intelligence-based, computational 
algorithms that rapidly mine the structural and performance attributes of our large and continuously growing library of protein 
variants. These computational outputs enable increasingly reliable predictions for next generation protein variants to be 
engineered, enabling time- and cost-efficient delivery of the targeted performance enhancements. In addition to its 
computational prowess, our CodeEvolver® protein engineering technology platform integrates additional modular 
competencies, including robotic high-throughput screening and genomic sequencing, organic chemistry and bioprocess 
development which are all coordinated to rapidly innovate novel, fit-for-purpose products. 

The core historical application of the technology has been in developing commercially viable biocatalytic manufacturing 
processes for more sustainable production of complex chemicals. It begins by conceptually designing the most cost-effective 
and practical process for a targeted product. We then develop optimized biocatalysts to enable the designed process, using our 
CodeEvolver® platform. Engineered biocatalyst candidates, numbering many thousands for each project, are then rapidly 
screened and validated using high throughput methods under process-relevant operating conditions. This approach results in an 
optimized biocatalyst that enables cost-efficient processes that are relatively simple to run in conventional manufacturing 
equipment. This also allows for efficient technical transfer of our processes to our manufacturing partners. 

We initially commercialized our CodeEvolver® protein engineering technology platform and products in the manufacture 
of small molecule pharmaceuticals, which remains a primary business focus. Our customers, which include many large, global 
pharmaceutical companies, use our technology, products and services in their process development and in manufacturing. 
Additionally, we have licensed our proprietary CodeEvolver® protein engineering technology platform to global pharmaceutical 
companies enabling them to use this technology, in house, to engineer enzymes for their own businesses. In May 2019, we 
entered into a Platform Technology Transfer and License Agreement (the “Novartis CodeEvolver® Agreement”) with Novartis. 
The Novartis CodeEvolver® Agreement (Codexis’ third such agreement with large pharma companies) allows Novartis to use 
our proprietary CodeEvolver® protein engineering platform technology in the field of human healthcare. 

As evidence of our strategy to extend our technology beyond pharmaceutical manufacturing, we have also used the 
technology to develop biocatalysts and enzyme products for use in a broader set of industrial markets, including several large 
verticals, such as food, feed, consumer care and fine chemicals. In addition, we are using our technology to develop enzymes 
for various life science related applications, such as next generation sequencing (“NGS”) and polymerase chain reaction 
(“PCR/qPCR”) for in vitro molecular diagnostic and genomic research applications. In December 2019, we entered into a 
license agreement to provide Roche Sequencing Solutions, Inc. with our first enzyme for this target market: the Company’s 
EvoT4™ DNA ligase. In June 2020, we also entered into a Master Collaboration and Research Agreement with MAI (the “MAI 
Agreement”) pursuant to which we are leveraging our CodeEvolver® platform technology to improve the DNA polymerase 
enzymes that are critical for enzymatic DNA synthesis.  

59 

 
Approximately six years ago, we began using the CodeEvolver® protein engineering technology platform to develop early 

stage, novel biotherapeutic product candidates, both in partnership with customers and for our own proprietary Codexis drug 
candidates. Our first program was for the potential treatment of phenylketonuria ("PKU") in humans. PKU is an inherited 
metabolic disorder in which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient. In 
October 2017, we entered into a Global Development, Option and License Agreement (the “Nestlé License Agreement”) with 
Societé des Produits Nestlé S.A., formerly known as Nestec Ltd. (“Nestlé Health Science") to advance CDX-6114, our enzyme 
biotherapeutic product candidate for the potential treatment of PKU. In February 2019, Nestlé Health Science exercised its 
option to obtain an exclusive license to develop and commercialize CDX-6114. Also in October 2017, we entered into the 
Nestlé SCA pursuant to which we and Nestlé Health Science are collaborating to leverage the CodeEvolver® platform 
technology to develop other novel enzymes for Nestlé Health Science’s established Consumer Care and Medical Nutrition 
business areas. In March 2020, we entered into a Strategic Collaboration and License Agreement (“Takeda Agreement”) with 
Shire Human Genetic Therapies, Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Company Limited (“Takeda”), for 
the research and development of novel gene therapies for certain disease indications, including the treatment of lysosomal 
storage disorders and a blood factor deficiency. 

See Note 5, "Collaborative Arrangements" in the Notes to the Consolidated Financial Statements set forth in Item 8 of this 

Annual Report on Form 10-K for further information. 

Recent Development - Pfizer (PAXLOVID™) 

In the first and second quarters of 2021, we began to receive purchase orders from Pfizer, Inc. (“Pfizer”) for large 
quantities of our proprietary enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical intermediate for its 
proprietary active pharmaceutical ingredient, nirmatrelvir.  Pfizer markets, sells and distributes nirmatrelvir, in combination 
with the active pharmaceutical ingredient ritonavir, as its PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets) product, which 
received emergency use authorization by the U.S. Food and Drug Administration (“FDA”) in late 2021 for the treatment of 
COVID-19 in humans. 

In 2021, we recognized approximately $34.5 million in revenue from the sale of quantities of CDX-616 to Pfizer. In 
addition, as of December 31, 2021, we have received additional purchase orders from Pfizer for delivery of a significant 
quantity of CDX-616 in 2022. We have received and currently expect to receive additional purchase orders from Pfizer for 
significant quantities of CDX-616 during the course of 2022 for delivery in 2022 and 2023. As of December 31, 2021, we have 
not yet executed a long-term purchase and sale agreement with Pfizer for CDX-616; with or without a long-term purchase and 
sale agreement, we currently expect that future orders for quantities of CDX-616 by Pfizer will continue to be based on the 
needs of Pfizer for quantities of CDX-616 and there will be no minimum purchase obligation on the part of Pfizer. 

Business Segments 

We manage our business as two business segments: Performance Enzymes and Novel Biotherapeutics. See Note 15, 
“Segment, Geographical and Other Revenue Information” in the Notes to the Consolidated Financial Statements set forth in 
Item 8 of this Annual Report on Form 10-K. 

Performance Enzymes 

We initially commercialized our CodeEvolver® protein engineering technology platform and products in the manufacture 
of small molecule pharmaceuticals and, to date, this continues to be our largest market served. Our customers, which include 
many large global pharmaceutical companies, use our technology, products and services in their manufacturing processes and 
process development. We have also used the technology to develop customized enzymes for use in other industrial markets. 
These markets consist of several large industrial verticals, including food, feed, consumer care, and fine chemicals. We also use 
our technology in the life sciences markets to develop enzymes for customers using NGS and PCR/qPCR for in vitro molecular 
diagnostic and molecular biology research applications, as well DNA/RNA synthesis and health monitoring applications. 

Novel Biotherapeutics 

We are also targeting new opportunities in the pharmaceutical industry to discover, improve, and/or develop biotherapeutic 

drug candidates. We believe that our CodeEvolver® protein engineering platform technology can be used to discover novel 
biotherapeutic drug candidates that will target human diseases that are in need of improved therapeutic interventions. Similarly, 
we believe that we can deploy our platform technology to improve specific characteristics of a customer’s pre-existing 
biotherapeutic drug candidate, such as its activity, stability or immunogenicity.

Business Update Regarding COVID-19 

We are subject to risks and uncertainties as a result of the current COVID-19 pandemic. The COVID-19 pandemic has 
presented a substantial public health and economic challenge around the world and is affecting our employees, communities 
and business operations, as well as the U.S. economy and other economies worldwide. The full extent to which the COVID-19 
pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future 
developments that are highly uncertain and may not be accurately predicted, including the duration and severity of the 
pandemic, the prevalence of more contagious and or virulent variants such as the Delta and Omicron variants, and the extent 
and severity of the impact on our customers, new information that may emerge concerning COVID-19, the actions taken to 
contain it or treat its impact and the economic impact on local, regional, national and international markets. 

In the United States, the impact of COVID-19, including governmental orders (“Orders”) governing the operation of 
businesses during the pandemic, caused the temporary closure of our Redwood City, California facilities and has disrupted our 
R&D operations. R&D operations for several projects were temporarily suspended from mid-March 2020 through the end of 
April 2020 in accordance with these Orders. In May 2020, we re-initiated limited R&D operations and have ramped up 
operations such that we are currently utilizing our normal R&D capacity while following county, state and federal COVID-19 
guidance for the protection of our employees. Additionally, we resumed manufacturing at our Redwood City pilot plant in May 
2020. 

To date, we and our collaboration partners have been able to continue to supply our enzymes to our customers worldwide, 
however, there can be no guarantee this will continue. Furthermore, our ability to provide future R&D services will continue to 
be impacted as a result of governmental orders and any disruptions in operations of our customers with whom we collaborate. 
We believe that these disruptions have had a minimal impact on revenue for the year ended December 31, 2021. The extent to 
which the pandemic may impact our business operations and operating results will continue to remain highly dependent on 
future developments, which are uncertain and cannot be predicted with confidence. 

As a result of the COVID-19 pandemic we have received purchase orders from Pfizer for large quantities of our proprietary 

enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical intermediate for its proprietary active 
pharmaceutical ingredient, nirmatrelvir, used by Pfizer in combination with the active pharmaceutical ingredient ritonavir, as its 
PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets) product for the treatment of COVID-19 infections in humans. These 
purchase orders have had substantial impact on our revenue in 2021.  

For additional information on the various risks posed by the COVID-19 pandemic, please read Item 1A. Risk Factors 

included in this Annual Report on Form 10-K. 

Recent Investing and Financing Activities 

In June 2020, we entered into a Stock Purchase Agreement with MAI pursuant to which we purchased 1,587,050 shares of 

MAI's Series A preferred stock for $1.0 million. In connection with the transaction, John Nicols, our President and Chief 
Executive Officer, also joined MAI’s board of directors. Concurrently with our initial equity investment, we entered into the 
MAI Agreement pursuant to which we are performing services utilizing our CodeEvolver® protein engineering platform 
technology to improve DNA polymerase enzymes in exchange for compensation in the form of additional shares of MAI's 
Series A preferred stock. In April 2021, we purchased an additional 1,000,000 shares of MAI's Series A preferred stock for $0.6 
million. In September 2021, we purchased 9,198,423 shares of MAI's Series B preferred stock for $7.0 million. As of 
December 31, 2021, we have 16,705,320 shares of MAI's Series A and B preferred stock that we have earned or purchased 
since executing the Stock Purchase Agreement with MAI.  

In November 2020, we announced the SynBio Innovation Accelerator (“Accelerator”) collaboration with Casdin Capital, 

LLC ("Casdin"). The goal of the Accelerator is to fund the early-stage companies with disruptive technology platforms or 
unique product development capabilities in the field of synthetic and industrial biotechnology. The first investment by Codexis 
associated with the Accelerator collaboration was made in Arzeda Corp., a privately-held computational protein design 
company that focuses on computational approaches to designing novel enzyme functionality. We invested $1.0 million in 
Arzeda and received a convertible subordinated note issued by Arzeda Corp. In July 2021, we converted the non-marketable 
debt security with a carrying value of $1.3 million into 207,070 shares of Series B-2 preferred stock of Arzeda Corp. 

In December 2020, we completed an underwritten public offering of 4,928,572 shares of our common stock, par value 
$0.0001 per share, at a public offering price of $17.50 per share. The net proceeds to us were approximately $80.8 million after 
deducting offering costs, underwriting discounts and commissions and other offering expenses of $5.5 million. 

61 

 
In May 2021, we filed a Registration Statement on Form S-3 with the SEC, that automatically became effective upon its 
filing, under which we may sell common stock, preferred stock, debt securities, warrants, purchase contracts, and units from 
time to time in one or more offerings. In May 2021, we entered into an Equity Distribution Agreement ("EDA") with Piper 
Sandler & Co ("PSC"), under which PSC, as our exclusive agent, at our discretion and at such times that we may determine 
from time to time, may sell over a three-year period from the execution of the EDA up to a maximum of $50.0 million of shares 
of our common stock. Under the terms of the EDA, PSC may sell the shares at market prices by any method that is deemed to 
be an "at the market offering" as defined in Rule 415 under the Securities Act of 1933, as amended. During the year ended 
December 31, 2021, no shares of our common stock were issued pursuant to the EDA.  

Results of Operations Overview 

Revenues were $104.8 million in 2021, a 52% increase from $69.1 million in 2020. Product revenue, which consists 
primarily of sales of biocatalysts, pharmaceutical intermediates, and Codex® biocatalyst panels and kits, was $70.7 million in 
2021, an increase of 134% compared with $30.2 million in 2020. The increase in product revenue was primarily due to $34.5 
million in revenue from Pfizer related to the purchase of our performance enzyme products and an increase in demand for 
enzymes used in the manufacture of branded pharmaceutical products. 

Research and development revenues, which include license, technology access and exclusivity fees, research service fees, 

milestone payments, royalties, and optimization and screening fees, totaled $34.1 million in 2021, a 12% decrease compared 
with $38.8 million in 2020. The decrease in research and development revenue was primarily due to lower license fees from 
Takeda under the Takeda Agreement and lower revenues from Novartis under the Novartis CodeEvolver® Agreement 
recognized this year compared to the prior year, partially offset by higher license fees from other existing collaboration 
agreements. 

Our products’ profitability is affected by many factors including the mix of products we sell. Our profit margins are 
affected by many factors including the costs of internal and third-party fixed and variable costs, including materials and 
supplies, labor, facilities and other overhead costs. Profit margin data is used as a management performance measure to provide 
additional information regarding our results of operations on a consolidated basis. Product gross margins increased to 69% in 
2021, compared to 55% in 2020 due to improved product mix resulting from sales to Pfizer and an increase in customer 
demand for branded pharmaceutical products. 

Research and development expenses were $55.9 million in 2021, an increase of 26% from $44.2 million in 2020. The 

increase was primarily due to an increase in costs associated with higher headcount, higher lab supplies, higher depreciation 
and other outside services, partially offset by a decrease in costs associated with outside services relating to Chemistry, 
Manufacturing and Controls ("CMC") and regulatory expenses. 

Selling, general and administrative expenses were $49.3 million in 2021, an increase of 41% compared to $35.0 million in 

2020. The increase was primarily due to an increase in costs associated with a higher headcount, increase in legal fees, higher 
stock-based compensation costs, higher outside and temporary services, partially offset by lower allocable expenses. 

Net loss was $21.3 million, or a net loss of $0.33 per share, in 2021 compared to a net loss of $24.0 million, or a net loss of 

$0.40 per share, in 2020. The decrease in net loss was primarily related to an increase in product revenue with higher margins, 
partially offset by higher operating expenses and lower research and development revenues. 

Cash and cash equivalents decreased to $116.8 million as of December 31, 2021 compared to $149.1 million as of 
December 31, 2020. In addition, net cash used in operations was $14.3 million in 2021, as compared to net cash used in 
operations of $16.5 million in 2020. We believe that based on our current level of operations, our existing cash and cash 
equivalents will provide adequate funds for ongoing operations, planned capital expenditures and working capital requirements 
for at least the next 12 months. 

In June 2017, we entered into a loan and security agreement with Western Alliance Bank that allowed us to borrow up to 
$10.0 million under a term loan, and allow us to borrow up to $5.0 million under a revolving credit facility with 80% of certain 
eligible accounts receivable as a borrowing base (the “Credit Facility”). Obligations under the Credit Facility are secured by a 
lien on substantially all of our personal property other than our intellectual property. In September 2021, we entered into the 
Ninth Amendment to the Credit Facility whereby we may draw on the term debt and the Revolving Line of Credit at any time 
prior to December 31, 2021 and October 1, 2024, respectively. Draws on the term debt are subject to customary conditions for 
funding. Our ability to take draws on the term debt expired on December 31, 2021. As of December 31, 2021, no amounts were 
borrowed under the Credit Facility and we were in compliance with the covenants for the Credit Facility. See Note 13, 
“Commitments and Contingencies” in the Notes to the Consolidated Financial Statements set forth in Item 8 of this Annual 
Report on Form 10-K.

Revenues typically fluctuate on a quarterly basis due to the variability in our customers' manufacturing schedules and the 
timing of our customers' clinical trials. In addition, we have limited internal capacity to manufacture enzymes. As a result, we 
are dependent upon the performance and capacity of third party manufacturers for the commercial scale manufacturing of the 
enzymes used in our pharmaceutical and fine chemicals business.  

We accept purchase orders for deliveries covering periods from one day up to 14 months from the date on which the order 

is placed. However, some of our purchase orders can be revised or cancelled by the customer without penalty. Considering

provides meaningful information that can be relied on to predict actual sales for future periods. 

2021 compared to 2020  

Total revenues increased by $35.7 million in 2021 to $104.8 million, as compared to 2020. The increase was driven by 
growth in product revenue of $40.4 million, or 134%, but partially offset by a decrease in research and development revenue of 
$4.7 million, or 12%. 

Product revenues, which consist primarily of sales of biocatalysts, pharmaceutical intermediates, and Codex® biocatalyst 
panels and kits, were $70.7 million in 2021, an increase of 134% compared with $30.2 million in 2020. The increase in product 
revenue was primarily due to $34.5 million in revenue from Pfizer and an increase in demand for enzymes used in the 
manufacture of branded pharmaceutical products. 

Research and development revenue decreased by $4.7 million in 2021 to $34.1 million, or 12% compared with $38.8 
million in 2020, primarily due to lower license and research and development fees from Takeda under the Takeda Agreement 
and lower revenues from the Novartis CodeEvolver® Agreement recognized this year compared to the prior year, partially offset 
by higher license fees from other existing collaboration agreements.  

2020 compared to 2019  

Total revenues increased by $0.6 million in 2020 to $69.1 million, as compared to 2019. The increase was driven by 
growth in product revenue of $0.8 million, or 3%, offset by a decrease in research and development revenue of $0.2 million or 
nominal percent. 

Product revenues were $30.2 million in 2020, an increase of 3% compared with $29.5 million in 2019. The increase in 
product revenue is primarily due to higher customer demand for enzymes used in the manufacture of branded pharmaceutical 
products. 

Research and development revenues decreased by $0.2 million in 2020 to $38.8 million compared with 39.0 million in 
2019, primarily due to lower revenues from the Novartis CodeEvolver® Agreement, a prior year functional license fee revenue 
from Nestlé Health Science, and a prior year milestone payment from GSK under the GSK CodeEvolver® Agreement, partially 
offset by the recognition of license fees from Takeda under the Takeda Agreement, and recognition of functional license fees 
revenue from Porton.

(1) Cost of product revenue comprises both internal and third-party fixed and variable costs, including materials and supplies, labor, facilities and other overhead costs associated 

with our product revenue. 

(2) Product gross margin is used as a performance measure to provide additional information regarding our results of operations on a consolidated basis. 

2021 compared to 2020  

Cost of product revenue increased by $8.5 million in 2021 to $22.2 million, as compared to 2020. The increase was 
primarily due to a higher volume of product sales and variations in product mix. The product gross margin increased to 69% in 
2021 as compared to 55% in 2020, primarily due to the sale of higher margin branded products. 

2020 compared to 2019 

Cost of product revenue decreased by $1.9 million in 2020 to $13.7 million, as compared to 2019. The decrease was 
primarily due to lower costs compared to costs associated with prior year product revenue. The product gross margin increased 
to 55% in 2020 as compared to 47% in 2019 due to improved product mix. 

Research and Development Expenses  

Research and development expenses consist of costs incurred for internal projects as well as collaborative research and 
development activities. These costs primarily consist of (i) employee-related costs, which include salaries and other personnel-
related expenses (including stock-based compensation), (ii) various allocable expenses, which include occupancy-related costs, 
supplies, depreciation of facilities and laboratory equipment, and (iii) external costs. Research and development expenses are 
expensed when incurred.  

2021 compared to 2020 

Research and development expenses were $55.9 million in 2021 compared to $44.2 million in 2020, an increase of $11.7 

million, or 26%. The increase was primarily due to $7.6 million in costs associated with higher headcount, $0.8 million in 
higher stock-based compensation expenses, $2.6 million in higher lab supplies, $2.2 million in higher allocable expenses, $1.1 
million increase in outside services, and $1.0 million in higher depreciation expenses, partially offset by a $3.7 million decrease 
in costs associated with outside services related to CMC and regulatory expenses. 

2020 compared to 2019  

Research and development expenses were $44.2 million in 2020 compared to $33.9 million in 2019, an increase of $10.3 
million, or 30%. The increase was primarily due to $5.0 million in costs associated with outside services relating to CMC and 
regulatory expenses, $3.4 million in costs associated with higher headcount, $1.5 million in higher allocable expenses which 
include occupancy-related costs and supplies, $0.4 million in higher outside services, and $0.3 million in higher depreciation 
expense and were partially offset by a decrease of $0.4 million in lab supply expenses. 

Selling, General and Administrative Expenses  

Selling, general and administrative expenses consist of employee-related costs, which include salaries and other personnel-

related expenses (including stock-based compensation), hiring and training costs, consulting and outside services expenses 
(including audit and legal counsel related costs), marketing costs, building lease costs, and depreciation and amortization 
expenses. 

2021 compared to 2020  

Selling, general and administrative expenses were $49.3 million in 2021 compared to $35.0 million in 2020, an increase of 
$14.3 million, or 41%. The increase was primarily due to an increase of $6.6 million in costs associated with higher headcount 
to support our growth, $3.1 million in higher stock-based compensation costs, $5.1 million increase in legal fees, $1.1 million 
in higher outside and temporary services, $1.0 million in higher facilities cost, and $0.4 million increase in allowance for credit 
losses, partially offset by a decrease of $3.0 million in allocable expenses. 

2020 compared to 2019  

Selling, general and administrative expenses were $35.0 million in 2020 compared to $31.5 million in 2019, an increase of 
$3.5 million or 11%. The increase was primarily due to increases of $1.7 million in salaries and personnel costs associated with 
higher headcount, $0.6 million in stock-based compensation expense, $0.8 million in consultants costs, $0.8 million in legal and 

65 

 
accounting fees, $0.7 million in facilities costs, $0.7 million in outside and temporary services, and $0.4 million in licensed 
technology, which were partially offset by decreases of $1.6 million in allocable expenses and $0.8 million in travel expenses.

Interest income increased by $0.1 million in 2021 compared to 2020, primarily due to earned interest income on a non-
marketable debt security, partially offset by a reduction in interest income from lower average interest rates on lower average 
cash balances. Interest income decreased by $0.9 million in 2020 compared to 2019, primarily due to lower average interest 
rates on declining average cash balances. 

Other Income (Expense), net 

Other income (expense), net, increased by $1.3 million in 2021 compared to 2020, primarily due to a $1.0 million gain 

from remeasurement on the carrying value of our investment in MAI. Other expense decreased by $0.5 million in 2020 
compared to 2019, primarily due to a $0.5 million write-down in the fair value of our investment in CO2 Solutions and 
fluctuations in foreign currency in 2019.

The provision for income taxes for 2021 was primarily due to the income tax withholding imposed by foreign taxing 
authorities on income earned in certain countries outside of the Unites States and remitted to the Unites States and the accrual 
of interest and penalties on historic uncertain tax positions. The provision for income taxes in 2020 was primarily due to foreign 
withholding taxes on certain sales to non-U.S. customers. The provision for income taxes in 2019 was primarily due to the 
accrual of interest and penalties on historic uncertain tax positions.  

Net Loss 

Net loss for 2021 was $21.3 million, or a net loss per basic and diluted share of $0.33. This compared to a net loss of $24.0 

million, or $0.40 per basic and diluted share for 2020. The decrease in net loss was primarily related to an increase in product 
revenue with higher margins, partially offset by higher operating expenses and lower research and development revenues. 

The net loss for 2020 was $24.0 million, or $0.40 per basic and diluted share. This compared to a net loss of $11.9 million, 

or $0.21 per basic and diluted share for 2019. The increase in net loss was primarily related to an increase in costs associated 
with outside services relating to CMC and regulatory expenses, higher headcount, higher consultants, higher stock 
compensation expenses and higher facility expense.

2021 compared to 2020  

Revenues from the Performance Enzymes segment increased by $42.4 million, or 88%, to $90.5 million in 2021, compared 

to $48.1 million in 2020. The increase in product revenue of $40.4 million, or 134%, to $70.7 million in 2021, compared to 
$30.2 million in 2020 was primarily due to $34.5 million in revenue from Pfizer and higher customer demand for enzymes used 
in the manufacture of branded pharmaceutical products. The increase in research and development revenue of $2.0 million, or 
11%, to $19.9 million in 2021, compared to $17.9 million in 2020 was primarily due to higher licenses fees from existing 
collaboration arrangements, partially offset by lower revenues from Novartis under the Novartis CodeEvolver® Agreement. 

Revenues from the Novel Biotherapeutics segment decreased by $6.7 million, or 32%, to $14.2 million in 2021, compared 
to $21.0 million in 2020. The decrease in revenue was primarily due to lower license and research and development fees from 
Takeda under the Takeda Agreement recognized this year compared to the prior year and a decrease in research and 
development revenue from Nestlé Health Science compared to last year. 

2020 compared to 2019 

Revenues from the Performance Enzymes segment decreased by $10.1 million, or 17%, to $48.1 million in 2020, 

compared to $58.2 million in 2019. The increase in product revenue of $0.8 million, or 3%, to $30.2 million in 2020, compared 
to $29.5 million in 2019, was primarily due to higher customer demand for enzymes used in the manufacture of branded 
pharmaceutical products. The decrease in research and development revenue of $10.8 million, or 38%, to $17.9 million in 2020, 
compared to $28.7 million in 2019 was primarily due to lower revenues from Novartis under the Novartis CodeEvolver® 
Agreement, a prior year milestone payment from GSK under the GSK CodeEvolver® Agreement, and lower license fees and 
revenue from Merck, partially offset by the recognition of functional license fees revenue from Porton in 2020. 

Revenues from the Novel Biotherapeutics segment increased by $10.6 million, or 103%, to $21.0 million in 2020, 

compared to $10.3 million in 2019. The increase in revenue was primarily due to recognition of license fees from Takeda under 
the Takeda Agreement, partially offset by a decrease in prior year functional license fee revenue from Nestlé Health Science.

2021 compared to 2020 

Research and development expense in the Performance Enzymes segment increased by $2.2 million, or 11%, to $23.1 
million in 2021, compared to $20.9 million in 2020. The increase was primarily due to an increase in costs associated with 
higher headcount, higher outside services expenses, and higher lab supplies, partially offset by lower allocable expenses.

Selling, general and administrative expense in the Performance Enzymes segment increased by $2.5 million, or 26%, to 
$12.1 million in 2021, compared to $9.6 million in 2020. The increase was primarily due to an increase in costs associated with 
higher headcount and allocable expenses, partially offset by lower outside services expenses.  

Research and development expense in the Novel Biotherapeutics segment increased by $8.5 million, or 39%, to $30.2 
million in 2021, compared to $21.7 million in 2020. The increase was primarily due to higher costs associated with higher 
headcount and allocable expenses but partially offset by reduction in costs associated with outside services relating to CMC and 
regulatory expenses. 

Selling, general and administrative expense in the Novel Biotherapeutics segment increased by $0.4 million, or 17%, to 
$2.8 million in 2021, compared to $2.4 million in 2020. The increase was primarily due to increase in costs associated with 
higher headcount and higher allocable expenses, partially offset by lower outside services expenses. 

2020 compared to 2019 

Research and development expense in the Performance Enzymes segment increased by $1.5 million, or 8%, to $20.9 

million in 2020, compared to $19.4 million in 2019. The increase was primarily due to an increase in costs associated with 
higher headcount, higher stock-based compensation expense, higher repairs and maintenance expense, and were partially offset 
by lower lab supply expenses and lower allocable expenses. 

Selling, general and administrative expense in the Performance Enzymes segment increased by $1.1 million, or 13%, to 
$9.6 million in 2020, compared to $8.5 million in 2019. The increase was primarily due to an increase in costs associated with 
licensed technology, outside services, stock-based compensation expense, and higher allocable expenses which were partially 
offset by lower travel expenses. 

Research and development expense in the Novel Biotherapeutics segment increased by $8.4 million, or 63%, to $21.7 
million in 2020, compared to $13.3 million in 2019. The increase was primarily due to an increase in costs associated with 
outside services relating to CMC and regulatory expenses for CDX-7108 which we are developing pursuant to our development 
agreement with Nestlé Health Science, higher headcount, higher outside services, and higher allocable expenses and were 
partially offset by lower lab supply expenses and consultant expense.  

Selling, general and administrative expense in the Novel Biotherapeutics segment increased by $0.1 million, or 6%, to $2.4 

million in 2020, compared to $2.2 million in 2019. The increase was primarily due to an increase in costs associated with 
headcount, licensed technology, consultants and stock-based compensation expense which were partially offset by lower 
allocable expenses, outside services, and travel expenses.

Income from operations in the Performance Enzymes segment increased by $29.2 million, or 760%, to $33.1 million, in 

2021, compared to $3.8 million in 2020. The increase in income from operations was primarily due to higher product revenue 
and research and development revenue, partially offset by higher costs and operating expenses. 

Loss from operations in the Novel Biotherapeutics segment increased by $15.6 million, or 502%, to $18.7 million in 2021 

compared to a loss from operations of $3.1 million in 2020. The increase in loss from operations was primarily due to lower 
research and development revenue from Takeda under the Takeda Agreement and decrease in research and development

2020 compared to 2019 

Income from operations in the Performance Enzymes segment decreased by $10.8 million, or 74%, to $3.8 million, in 

2020, compared to $14.7 million in 2019. The decrease in income from operations was primarily due to decrease in research 
and development revenue and increases in research and development costs and selling, general and administrative expenses. 

Loss from operations in the Novel Biotherapeutics segment decreased by $2.1 million, or 40%, to $3.1 million in 2020 

compared to a loss from operations of $5.2 million in 2019. The decrease in loss from operation was primarily due to the 
recognition of license fees from Takeda under the Takeda Agreement, partially offset by a decrease in prior year functional 
license fee revenue from Nestlé Health Science, an increase in costs associated with outside services relating to CMC and 
regulatory expenses, higher headcount, higher outside services, and higher allocable expenses. 

Liquidity and Capital Resources 

Liquidity is the measurement of our ability to meet working capital needs and to fund capital expenditures. We have 
historically funded our operations primarily through cash generated from operations, stock option exercises and public and 
private offerings of our common stock. We also have the ability to borrow up to $5.0 million under our Credit Facility. We 
actively manage our cash usage and investment of liquid cash to ensure the maintenance of sufficient funds to meet our working 
capital needs. Our cash and cash equivalents are held in U.S banks. 

The following summarizes our cash and cash equivalents balance and working capital as of December 31, 2021, 2020 and 

2019 (in thousands):

In addition to our existing cash and cash equivalents, we are eligible to earn milestone and other contingent payments for 

the achievement of defined collaboration objectives and certain royalty payments under our collaboration agreements. Our 
ability to earn these milestone and contingent payments and the timing of achieving these milestones is primarily dependent 
upon the outcome of our collaborators’ research and development activities and is uncertain at this time. Under the Merck 
CodeEvolver® Agreement, we are eligible to receive payments of up to $15.0 million for each commercial API that is 
manufactured by Merck using one or more novel enzymes developed by Merck using the CodeEvolver® technology. In 
addition, under the GSK CodeEvolver® Agreement, depending upon GSK's successful application of the licensed technology, 
we have the potential to receive additional contingent payments that range from $5.75 million to $38.5 million per project.  

In May 2019, we entered into a Platform Technology Transfer and License Agreement with Novartis. The Novartis 
CodeEvolver® Agreement allows Novartis to use Codexis’ proprietary CodeEvolver® protein engineering platform technology 
in the field of human healthcare. Pursuant to the agreement, we received an upfront payment of $5.0 million shortly after the 
effective date. We completed the second technology milestone transfer under the agreement and received a milestone payment 
of $4.0 million in 2020. We have also received aggregate of $5.0 million for the completion of the third technology milestone in 
2021. In consideration for the continued disclosure and license of improvements to the technology and materials during a multi-
year period that began on the conclusion of the Technology Transfer Period (“Improvements Term”), Novartis will pay Codexis 
an additional $8.0 million in aggregate over four years. 

In October 2017, we entered into the Nestlé License Agreement with Nestlé Health Science. Pursuant to the Nestlé License 

Agreement, Nestlé Health Science paid us an upfront cash payment and milestone payments after dosing the first subjects in a 
first-in-human Phase 1a dose-escalation trail with CDX-6114 and achievement of a formulation relating to CDX-6114. We are 
also eligible to receive payments from Nestlé Health Science under the Nestlé License Agreement that include (i) development 
and approval milestones of up to $85.0 million, (ii) sales-based milestones of up to $250.0 million in the aggregate, which 
aggregate amount is achievable if net sales exceed $1.0 billion in a single year, and (iii) tiered royalties, at percentages ranging 
from the mid-single digits to low double-digits, of net sales of product.  

70 

 
  
 
 
 
We are actively collaborating with new and existing customers in the pharmaceutical and food industries. We believe that 

we can utilize our current products and services, and develop new products and services, to increase our revenues and gross 
margins in future periods. 

We have historically experienced negative cash flows from operations as we continue to invest in key technology 
development projects and improvements to our CodeEvolver® protein engineering technology platform, and expand our 
business development and collaboration with new customers. Our cash flows from operations will continue to be affected 
principally by product sales and product gross margins, sales from licensing our technology to major pharmaceutical 
companies, and collaborative research and development services provided to customers, as well as our headcount costs, 
primarily in research and development. Our primary source of cash flows from operating activities is cash receipts from our 
customers for purchases of products, collaborative research and development services, and licensing our technology to major 
pharmaceutical companies. Our largest uses of cash from operating activities are for employee-related expenditures, rent 
payments, inventory purchases to support our product sales and non-payroll research and development costs. 

Equity Distribution Agreement 

In May 2021, we entered into an Equity Distribution Agreement ("EDA") with Piper Sandler & Co ("PSC"), under which 

PSC, as our exclusive agent, at our discretion and at such times that we may determine from time to time, may sell over a three-
year period from the execution of the EDA up to a maximum of $50.0 million of shares of our common stock. During the year 
ended December 31, 2021, no shares of our common stock were issued pursuant to the EDA. As of December 31, 2021, $50.0 
million of shares remained available for sale under the EDA. Sales of our common stock under this arrangement could be 
subject to business, economic or competitive uncertainties and contingencies, many of which may be beyond our control, and 
which could cause actual results from the sale of our common stock to differ materially from expectations.  

Credit Facility 

In June 2017, we entered into the Credit Facility with Western Alliance Bank which consists of term debt for loans that 

allowed us to borrow up to $10.0 million and a revolving credit facility that allows us to borrow up to $5.0 million with a 
certain eligible accounts receivable borrowing base of 80% of eligible accounts receivable. In September 2021, we entered into 
the Ninth Amendment to the Credit Facility whereby we may draw on the Term Debt and the Revolving Line of Credit at any 
time prior to December 31, 2021 and October 1, 2024, respectively, subject to customary conditions for funding including, 
among others, that no event of default exists. Draws on the Credit Facility are secured by a lien on substantially all of our 
personal property other than our intellectual property. On October 1, 2024, loans drawn under the Term Debt mature and the 
Revolving Line of Credit terminate. Our right to take draws on the term debt expired on December 31, 2021 and no amounts 
were drawn under the Credit Facility as of December 31, 2021. The Credit Facility requires us to maintain compliance with 
certain financial covenants including attainment of certain lender-approved projections or maintenance of certain minimum 
cash levels. Restrictive covenants in the Credit Facility restrict the payment of dividends or other distributions. At 
December 31, 2021, we were in compliance with the covenants for the Credit Facility. For additional information about our 
contractual obligations, see Note 13, “Commitments and Contingencies” in the Notes to the Consolidated Financial Statements 
set forth in Item 8 of this Annual Report on Form 10-K. 

We believe that, based on our current level of operations, our existing cash and cash equivalents will provide adequate 
funds for ongoing operations, planned capital expenditures and working capital requirements for at least the next 12 months.  

71 

 
However, we may need additional capital if our current plans and assumptions change. In addition, we may choose to seek 
other sources of capital even if we believe we have generated sufficient cash flows to support our operating needs. Our need for 
additional capital will depend on many factors, including the financial success of our business, the spending required to develop 
and commercialize new and existing products, the effect of any acquisitions of other businesses, technologies or facilities that 
we may make or develop in the future, our spending on new market opportunities, and the potential costs for the filing, 
prosecution, enforcement and defense of patent claims, if necessary. If our capital resources are insufficient to meet our capital 
requirements, and we are unable to enter into or maintain collaborations with partners that are able or willing to fund our 
development efforts or commercialize any products that we develop or enable, we will have to raise additional funds to 
continue the development of our technology and products and complete the commercialization of products, if any, resulting 
from our technologies. If future financings involve the issuance of equity securities, our existing stockholders would suffer 
dilution. If we raise debt financing or enter into credit facilities, we may be subject to restrictive covenants that limit our ability 
to conduct our business. We may not be able to raise sufficient additional funds on terms that are favorable to us, if at all. If we 
fail to raise sufficient funds and fail to generate sufficient revenues to achieve planned gross margins and to control operating 
costs, our ability to fund our operations, take advantage of strategic opportunities, develop products or technologies, or 
otherwise respond to competitive pressures could be significantly limited. If this happens, we may be forced to delay or 
terminate research or development programs or the commercialization of products resulting from our technologies, curtail or 
cease operations or obtain funds through collaborative and licensing arrangements that may require us to relinquish commercial 
rights, or grant licenses on terms that are not favorable to us. If adequate funds are not available, we will not be able to 
successfully execute our business plan or continue our business.

common stock after deducting underwriting discounts and commission and related costs and proceeds from the exercises of 
employee stock options which were partially offset by the payment of taxes related to the net share settlement of equity awards. 

Off-Balance Sheet Arrangements 

As of December 31, 2021, we had no off-balance sheet arrangements as defined in Item 303(a)(4) of Regulation S-K as 

promulgated by the SEC. 

Critical Accounting Policies and Estimates 

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated 

financial statements. The consolidated financial statements have been prepared in conformity with generally accepted 
accounting principles in the United States and include our accounts and the accounts of our wholly owned subsidiaries. The 
preparation of our consolidated financial statements requires our management to make estimates, assumptions, and judgments 
that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 
financial statements, and the reported amounts of revenues and expenses during the applicable periods. Management bases its 
estimates, assumptions and judgments on historical experience and on various other factors that are believed to be reasonable 
under the circumstances. Different assumptions and judgments would change the estimates used in the preparation of our 
consolidated financial statements, which, in turn, could change the results from those reported. Our management evaluates its 
estimates, assumptions and judgments on an ongoing basis. 

The critical accounting policies requiring estimates, assumptions, and judgments that we believe have the most significant 

impact on our consolidated financial statements are described below. 

Revenue Recognition 

Our revenues are derived primarily from product revenue and collaborative research and development agreements. The 

majority of our contracts with customers typically contain multiple products and services. We account for individual products 
and services separately if they are distinct-that is, if a product or service is separately identifiable from other items in the 
contract and if a customer can benefit from it on its own or with other resources that are readily available to the customer.  

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under our product revenue 

and collaborative research and development agreements, we perform the following steps: (i) identification of the promised 
goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, 
including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the 

73 

 
constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated 
selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation. 

The majority of our collaborative contracts contain multiple revenue streams such as upfront and/or annual license fees, 
research and development services, contingent milestone payments upon achievement of contractual criteria, and royalty fees 
based on the licensees' product revenue or usage, among others. We determine the stand-alone selling price (“SSP”) and 
allocate consideration to distinct performance obligations. Typically, we base our SSPs on our historical sales. If an SSP is not 
directly observable, then we estimate the SSP taking into consideration market conditions, forecasted sales, entity-specific 
factors and available information about the customer. We estimate the SSP for license rights by using a discounted cash flow 
method which includes the following key assumptions: the development timelines, revenue forecasts, commercialization 
expenses, discount rate, and the probability of technical and regulatory success. For licenses that have been previously sold to 
other customers, we use historical information to determine SSP. 

We account for a contract with a customer when there is approval and commitment from both parties, the rights of the 
parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is 
probable. Non-cancellable purchase orders received from customers to deliver a specific quantity of product, when combined 
with our order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and 
constitute a contract with a customer. 

We measure revenue based on the consideration specified in the contract with each customer, net of any sales incentives 

and taxes collected on behalf of government authorities. We recognize revenue in a manner that best depicts the transfer of 
promised goods or services to the customer, when control of the product or service is transferred to a customer. We make 
significant judgments when determining the appropriate timing of revenue recognition. 

The following is a description of principal activities from which we generate revenue: 

Product Revenue 

Product revenue consist of sales of biocatalysts, pharmaceutical intermediates and Codex® biocatalyst panels and kits. A 
majority of our product revenue is made pursuant to purchase orders or supply agreements and is recognized either at a point in 
time when the control of the product has been transferred to the customer typically upon shipment or over time as the product is 
manufactured because we have a right to payment from the customer under a binding, non-cancellable purchase order, and there 
is no alternate use of the product for us as it is specifically made for the customer’s use.  

Certain of our agreements provide options to customers which they can exercise at a future date, such as the option to 
purchase our product during the contract duration at discounted prices and an option to extend their contract, among others. In 
accounting for customer options, we determine whether an option is a material right and this requires us to exercise significant 
judgment. If a contract provides the customer an option to acquire additional goods or services at a discount that exceeds the 
range of discounts that we typically give for that product or service, or if the option provides the customer certain additional 
goods or services for free, the option may be considered a material right. If the contract gives the customer the option to acquire 
additional goods or services at their normal SSPs, we would likely determine that the option is not a material right and, 
therefore, account for it as a separate performance obligation when the customer exercises the option. We primarily account for 
options which provide material rights using the alternative approach available under ASC 606, as we concluded we meet the 
criteria for using the alternative approach. Therefore, the transaction price is calculated as the expected consideration to be 
received for all the goods and services we expect to provide. We update the transaction price for expected consideration, subject 
to constraint, each reporting period if our estimate of future goods to be ordered by customers change.  

Research and Development Revenues 

We perform research and development activities as specified in each respective customer agreement. We identify each 
performance obligation in our research and development agreements at contract inception. We allocate the consideration to each 
distinct performance obligation based on the estimated SSP of each performance obligation. Performance obligations included 
in our research and services agreements typically include research and development services for a specified term, periodic 
reports and small samples of enzyme produced. 

The majority of our research and development agreements are based on a contractual rate per dedicated project team 

working on the project. The underlying product that we develop for customers does not create an asset with an alternative use to 
us and the customer receives benefits as we perform the work towards completion. Thus, our performance obligations are 
generally satisfied over time as the service is performed. We utilize an appropriate method of measuring progress towards the 
completion of our performance obligations to determine the timing of revenue recognition. For each performance obligation 
that is satisfied over time, we recognize revenue using a single measure of progress, typically based on hours incurred. 

74 

 
Our contracts frequently provide customers with rights to use or access our products or technology, along with other 
promises or performance obligations. Under ASC 606, we must first determine whether the license is distinct from other 
promises, such as our promise to perform research and development services. If we determine that the customer cannot benefit 
from the license without our services, the license will be accounted for as combined with the other performance obligations. If 
we determine that a license is distinct, we would recognize an allocable portion of the transaction price when the license is 
transferred to the customer, and the customer can use and benefit from it. We estimate the SSP for license rights by using 
historical information if licenses have been previously sold to customers and for new licenses, we consider multiple methods, a 
discounted cash flow method which includes the following key assumptions: the development timelines, revenue forecasts, 
commercialization expenses, discount rate, and the probability of technical and regulatory success.  

At the inception of each arrangement that includes variable consideration such as development milestone payments, we 

evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the 
transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the 
associated milestone value is included in the transaction price. Milestone payments that are not within our control or the 
licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The 
transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which we 
recognize revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent 
reporting period, we re-evaluate the probability of achievement of such development milestones and any related constraint, and 
if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up 
basis, which would affect license, collaboration and other revenues and earnings in the period of adjustment. 

Our CodeEvolver® platform technology transfer collaboration agreements typically include license fees, upfront fees, and 

variable consideration in the form of milestone payments, and sales or usage-based royalties. We have recognized revenues 
from our platform technology transfer agreements over time. 

We also have an agreement under which we have granted a functional license to some elements of our biocatalyst 

technology. We will recognize revenues for the functional license at a point in time when the control of the license transfers to 
the customer. 

For license agreements that include sales or usage-based royalty payments to us for which the license is the predominant 
item to which the royalty relates, we do not recognize revenue until the underlying sales of the product or usage has occurred. 
At the end of each reporting period, we estimate the royalty amount. We recognize revenue at the later of (i) when the related 
sale of the product occurs, or (ii) when the performance obligation to which some or all of the royalty has been allocated has 
been satisfied, or partially satisfied. 

Stock-Based Compensation 

We use the Black-Scholes-Merton option pricing model to estimate the fair value of options granted under our equity 
incentive plans. The Black-Scholes-Merton option pricing model requires the use of assumptions, including the expected term 
of the award and the expected stock price volatility. The expected term is based on historical exercise behavior on similar 
awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. We use 
historical volatility to estimate expected stock price volatility. The risk-free rate assumption is based on United States Treasury 
instruments whose terms are consistent with the expected term of the stock options. The expected dividend assumption is based 
on our history and expectation of dividend payouts. 

Restricted Stock Units (“RSUs”), Restricted Stock Awards (“RSAs”) and performance-contingent restricted stock units 
(“PSUs”) are measured based on the fair market values of the underlying stock on the dates of grant. Performance based options 
(“PBOs”) are measured using Black-Scholes-Merton option pricing model. The vesting of PBOs and PSUs awarded is 
conditioned upon the attainment of one or more performance objectives over a specified period and upon continued 
employment through the applicable vesting date. At the end of the performance period, shares of stock subject to the PBOs and 
PSUs vest based upon both the level of achievement of performance objectives within the performance period and continued 
employment through the applicable vesting date. 

Stock-based compensation expense is calculated based on awards ultimately expected to vest and is reduced for estimated 
forfeitures at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. 
The estimated annual forfeiture rates for stock options, RSUs, PSUs, PBOs, and RSAs are based on historical forfeiture 
experience. 

The estimated fair value of stock options, RSUs and RSAs are expensed on a straight-line basis over the vesting term of the 
grant and the estimated fair value of PSUs and PBOs are expensed using an accelerated method over the term of the award once 
management has determined that it is probable that the performance objective will be achieved. Compensation expense is 

75 

 
recorded over the requisite service period based on management's best estimate as to whether it is probable that the shares 
awarded are expected to vest. Management assesses the probability of the performance milestones being met on a continuous 
basis. 

Lease Accounting 

We determine if an arrangement is a lease at inception. Where an arrangement is a lease we determine if it is an operating 

lease or a finance lease. At lease commencement, we record a lease liability and corresponding ROU asset. Lease liabilities 
represent the present value of our future lease payments over the expected lease term which includes options to extend or 
terminate the lease when it is reasonably certain those options will be exercised. The present value of our lease liability is 
determined using our incremental collateralized borrowing rate at lease inception. ROU assets represent our right to control the 
use of the leased asset during the lease and are recognized in an amount equal to the lease liability for leases with an initial term 
greater than 12 months. Over the lease term we use the effective interest rate method to account for the lease liability as lease 
payments are made and the ROU asset is amortized to consolidated statement of operations in a manner that results in straight-
line expense recognition.  

We elected to apply the practical expedient for short-term leases and accordingly do not apply lease recognition 

requirements for short-term leases. Instead, we recognize payments related to these arrangements in the consolidated statement 
of operations as lease costs on a straight-line basis over the lease term. 

Investment in Non-Marketable Securities 

Investment in Non-Marketable Equity Securities 

We measure investments in non-marketable equity securities without a readily determinable fair value using a measurement 

alternative that measures these securities at the cost method minus impairment, if any, plus or minus changes resulting from 
observable price changes on a non-recurring basis. Gains and losses on these securities are recognized in other income 
(expense), net. 

Investment in Non-Marketable Debt Securities 

We measure available for sale investments in non-marketable debt at fair value. Unrealized gains and losses on these 

securities are recognized in other comprehensive income until realized. Non-marketable debt securities are classified as 
available-for-sale securities. 

We classify non-marketable debt securities as Level 3 in the fair value hierarchy because we estimate the fair value based 
on a qualitative analysis using the most recent observable transaction price and other significant unobservable inputs including 
volatility, rights, and obligations of the securities we hold. Significant changes to the unobservable inputs may result in a 
significantly higher or lower fair value estimate. We may value these securities based on significant recent arms-length 
transactions with sophisticated non-strategic unrelated new investors. 

We evaluate both equity and debt securities for impairment when circumstances indicate that we may not be able to recover 
the carrying value. We may impair these securities and establish an allowance for a credit loss when we determine that there has 
been an “other-than-temporary” decline in estimated fair value of the debt or equity security compared to its carrying value. We 
calculate the estimated fair value of these securities using information from the investee, which may include: 

• 

• 

• 

• 

• 

• 

Audited and unaudited financial statements; 

Projected technological developments of the company; 

Projected ability of the company to service its debt obligations; 

If a deemed liquidation event were to occur; 

Current fundraising transactions; 

Current ability of the company to raise additional financing if needed; 

• 
company; 

Changes in the economic environment which may have a material impact on the operating results of the 

• 

• 

Contractual rights, obligations or restrictions associated with the investment; and 

Other factors deemed relevant by our management to assess valuation. 

76 

 
• 

The valuation may be reduced if the company's potential has deteriorated significantly. If the factors that led 

to a reduction in valuation are overcome, the valuation may be readjusted. 

Recent Accounting Pronouncements 

See Note 2, “Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to the Consolidated 

Financial Statements set forth in Item 8 of this Annual Report on Form 10-K for a full description of recent accounting 
standards, including the respective dates of adoption and effects on our consolidated financial position, results of operations and 
cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Interest Rate Sensitivity 

Our unrestricted cash and cash equivalents total $116.8 million at December 31, 2021. We primarily invest these amounts 

in money market funds which are held for working capital purposes. We do not enter into investments for trading or speculative 
purposes. As of December 31, 2021, the effect of a hypothetical 10% decrease in market interest rates would have an 
immaterial impact on a potential loss in future interest income and cash flows. 

In June 2017, we entered into a Credit Facility with Western Alliance Bank consisting of term loans up to $10.0 million, 
and advances under a revolving line of credit up to $5.0 million. Term loans made under the Term Debt bear interest at variable 
rate through maturity at the greater of (i) 3.75% or (ii) the sum of (A) Index Rate (prime rate published in the Money Rates 
section of the Western Edition of The Wall Street Journal plus (B) 0.50%. Advances made under the Revolving Line of Credit 
bear interest at a variable annual rate equal to the greater of (i) 4.25% or (ii) the sum of (A) the prime rate plus (B) 1.00%. 
Increases in these variable interest rates will increase our future interest expense and decrease our results of operations and cash 
flows. Our right to take draws on the long term debt expired on December 31, 2021 and no amounts were drawn under the 
Credit Facility as of December 31, 2021. Our exposure to interest rates risk relates to our 2017 Credit Facility with variable 
interest rates, where an increase in interest rates may result in higher borrowing costs. Since we have no outstanding borrowings 
under our 2017 Credit Facility as of December 31, 2021, the effect of a hypothetical 10% change in interest rates would not 
have any impact on our interest expense. 

Foreign Currency Risk 

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. In 

periods when the USD declines in value as compared to the foreign currencies in which we incur expenses, our foreign-
currency based expenses increase when translated into United States dollars. Although substantially all of our sales are 
denominated in United States dollars, future fluctuations in the value of the USD may affect the price competitiveness of our 
products outside the United States. Our most significant foreign currency exposure is due to non-functional currency 
denominated monetary assets, primarily currencies denominated in other than their functional currency. These non-functional 
currency denominated monetary assets are subject to re-measurement which may create fluctuations in other expense, net, a 
component in our consolidated statement of operations and in the fair value of the assets in the consolidated balance sheets. As 
of December 31, 2021, the effect of a hypothetical 10% unfavorable change in exchange rates on currencies denominated in 
other than their functional currency would result in a potential loss in future earnings in our consolidated statement of 
operations and a reduction in the fair value of the assets of approximately $46 thousand. We did not engage in hedging 
transactions in 2021, 2020 and 2019. 

Investment in Non-Marketable Equity Securities 

We own investments in non-marketable equity securities without readily determinable fair values. We may value these 

equity securities based on significant recent arms-length equity transactions with sophisticated non-strategic unrelated 
investors, providing the terms of these security transactions are substantially similar to the security transactions terms between 
the investors and us. The impact of the difference in transaction terms on the market value of the portfolio company may be 
difficult or impossible to quantify.

Opinion on the Consolidated Financial Statements  

We have audited the accompanying consolidated balance sheets of Codexis, Inc. (the “Company”) as of December 31, 2021 and 
2020, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the 
period ended December 31, 2021, and the related notes (collectively referred to as the “Consolidated Financial Statements”). In 
our opinion, the Consolidated Financial Statements present fairly, in all material respects, the financial position of the Company 
at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period 
ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. 

We also have audited,  in  accordance with the standards of  the  Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in 
Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (“COSO”) and our report dated February 28, 2022 expressed an unqualified opinion thereon. 

Basis for Opinion 

These Consolidated Financial Statements are the responsibility of the Company’s management. Our responsibility is to express 
an  opinion  on  the  Company’s  Consolidated  Financial  Statements  based  on  our  audits.  We  are  a  public  accounting  firm 
registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)  (“PCAOB”)  and  are  required  to  be 
independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and 
regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit  to  obtain  reasonable  assurance  about  whether  the  Consolidated  Financial  Statements  are  free  of  material  misstatement, 
whether due to error or fraud.  

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  Consolidated  Financial 
Statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included 
examining, on a test basis, evidence regarding the amounts and disclosures in the Consolidated Financial Statements. Our audits 
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating 
the overall presentation of the Consolidated Financial Statements. We believe that our audits provide a reasonable basis for our 
opinion. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the Consolidated Financial 
Statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the Consolidated Financial Statements and (2) involved our especially challenging, subjective, 
or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the Consolidated 
Financial Statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate 
opinions on the critical audit matter or on the accounts or disclosures to which it relates. 

Revenue Recognition 

As described in Notes 2 and 3 to the Consolidated Financial Statements, the Company recognizes revenue in a manner that best 
depicts the transfer of promised  goods  or services to the customer,  when control of the product  or  service  is  transferred to  a 
customer.  The  Company's  contracts  with  customers  include  enzyme  supply,  licensing,  and  collaborative  research  and 
development agreements. Contracts with customers may contain multiple performance obligations and may contain up-front or 
annual  license  fees,  fees  for  full  time  employee  research  and  development  services,  contingent  milestone  payments  upon 
achievement  of  contractual  criteria,  and  royalty  fees  based on  the  licensees'  product  revenue  or  usage. The  Company makes 
significant judgments in determining revenue recognition for customer contracts.  

We identified management’s significant judgments and estimates related to revenue recognition for contracts with customers as 
a  critical  audit  matter. Auditing  the  evaluation  of  distinct  performance  obligations,  determination  and  estimation  of  material 
rights,  determination  of  standalone  selling  prices,  determination  of  the  pattern  of  transfer  of  control  for  each  distinct 

80 

 
 
 
 
 
 
 
 
 
 
 
 
performance  obligation  and  estimation  of  variable  consideration  required  significant  audit  effort  and  subjective  judgments  in 
evaluating management's estimates.  

The primary procedures we performed to address this critical audit matter included:  

•  Testing the design and operating effectiveness of internal controls relating to the identification of distinct performance 
obligations and  material  rights,  the  determination of the timing of revenue recognition, the estimation of  standalone 
selling prices, and the estimation of variable consideration.  

•  Examining a sample of revenue contracts and other source documents to test management's identification of significant 
terms  for  completeness,  including  the  identification  of distinct  performance  obligations,  material  rights  and  variable 
consideration including sending confirmations to a sample of customers to confirm our understanding of the parties’ 
rights and obligations. 

•  Assessing  the  reasonableness  of  management's  estimates  and  assumptions  used  in  determining  stand-alone  selling 

prices for new products and services and those products and services that are not sold separately.  

•  Evaluating the reasonableness of management’s judgments and estimates used to assess the stand-alone selling prices 
for  new  functional  licenses  when  granted  to  customers  as  part  of  contracts  containing  multiple  performance 
obligations. 

•  Evaluating  the  reasonableness  and  accuracy  of  management’s  judgments  and  estimates  used  in  accounting  for 
identified  material  rights,  including  transactions  accounted  for  under  the  alternative  approach  to  estimating  the 
standalone selling price of a material right. This includes testing management’s estimates of the expected consideration 
from the customer’s exercise of options. 

•  Assessing  the  reasonableness  of  management’s  judgments and  estimates  to  calculate  variable  consideration,  and  the 

timing of recognizing the related revenue subject to any constraints.   

•  Evaluating the appropriateness of management’s determination of whether identified performance obligations meet the 

criteria for over-time revenue recognition, including whether certain products and services have alternative use.

Opinion on Internal Control over Financial Reporting 

We have audited Codexis, Inc.’s (the “Company’s”) internal control over financial reporting as of December 31, 2021, based on 
criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (the “COSO criteria”). In our opinion, the Company maintained, in all material respects, effective 
internal control over financial reporting as of December 31, 2021, based on the COSO criteria.  

We also have audited, in  accordance with the standards of  the  Public Company Accounting Oversight Board (United States) 
(“PCAOB”),  the  consolidated  balance  sheets  of  the  Company  as  of  December 31,  2021  and  2020,  the  related  consolidated 
statements  of  operations,  stockholders’  equity,  and  cash  flows  for  each  of  the  three  years  in  the  period  ended  December 31, 
2021, and the related notes, and our report dated February 28, 2022 expressed an unqualified opinion thereon. 

Basis for Opinion 

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its 
assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in  the  accompanying  “Item  9A, 
Management’s  Report  on  Internal  Control  over  Financial  Reporting”.  Our  responsibility  is  to  express  an  opinion  on  the 
Company’s  internal  control  over  financial  reporting  based  on  our  audit.  We  are  a  public  accounting  firm  registered  with  the 
PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We  conducted  our  audit  of  internal  control  over  financial  reporting  in  accordance  with  the  standards  of  the  PCAOB.  Those 
standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control 
over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal 
control over financial  reporting, assessing the risk  that a material weakness exists, and testing  and evaluating the design  and 
operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures 
as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control over Financial Reporting 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted  accounting  principles. A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures 
that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and 
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
company; and (3) provide  reasonable  assurance  regarding prevention or timely detection  of unauthorized  acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements. 

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also, 
projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements 

Note 1. Description of Business  

In these notes to the Consolidated Financial Statements, the “Company,” “we,” “us,” and “our” refers to Codexis, Inc. and 

its subsidiaries on a consolidated basis. 

We discover, develop and sell enzymes and other proteins that deliver value to our clients in a growing set of industries to 

commercialize an increasing number of novel enzymes, both as proprietary Codexis products and in partnership with our 
customers. 

We report our financial results based on two reportable segments: Performance Enzymes and Novel Biotherapeutics. The 
segment information aligns with how the chief operating decision maker (CODM), who is our Chief Executive Officer (CEO), 
reviews and manages the business. 

Business Update Regarding COVID-19 

We are subject to risks and uncertainties as a result of the current COVID-19 pandemic. The COVID-19 pandemic has 
presented a substantial public health and economic challenge around the world and is affecting our employees, communities 
and business operations, as well as the U.S. economy and other economies worldwide. The full extent to which the COVID-19 
pandemic will directly or indirectly impact our business, results of operations and financial condition will depend on future 
developments that are highly uncertain and may not be accurately predicted, including the duration and severity of the 
pandemic, the prevalence of more contagious and or virulent variants such as the Delta and Omicron variants, and the extent 
and severity of the impact on our customers, new information that may emerge concerning COVID-19, the actions taken to 
contain it or treat its impact and the economic impact on local, regional, national and international markets. 

In the United States, the impact of COVID-19, including Orders governing the operation of businesses during the 

pandemic, caused the temporary closure of our Redwood City, California facilities and disrupted our R&D operations in 2020. 
R&D operations for several projects were temporarily suspended from mid-March 2020 through the end of April 2020 in 
accordance with these Orders. In May 2020, we initiated limited R&D operations and resumed manufacturing operations at our 
Redwood City pilot plant and have ramped up operations such that we are currently utilizing our normal R&D capacity while 
following county, state and federal COVID-19 guidance for the protection of our employees. 

To date, we and our collaboration partners have been able to continue to supply our enzymes to our customers worldwide, 

however, there can be no guarantee this will continue. Furthermore, our ability to provide future research and development 
("R&D") services may continue to be impacted as a result of governmental orders ("Orders") and any disruptions in operations 
of our customers with whom we collaborate. We believe that these disruptions have had a minimal impact on revenue for the 
year ended December 31, 2021. The extent to which the pandemic may impact our business operations and operating results 
will continue to remain highly dependent on future developments, which are uncertain and cannot be predicted with confidence. 

Note 2. Basis of Presentation and Summary of Significant Accounting Policies 

Basis of Presentation and Principles of Consolidation 

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting 

principles in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange 
Commission ("SEC") and include the accounts of Codexis, Inc. and its wholly-owned subsidiaries.  

Certain prior year amounts have been reclassified in the Consolidated Statements of Cash Flows to conform to the 2021 

presentation, however these reclassifications had no effect on the reported results of operations.  

The consolidated financial statements include the accounts of Codexis, Inc. and its wholly owned subsidiaries. All 

intercompany balances and transactions have been eliminated in consolidation. 

Use of Estimates 

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates, 

judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses and related 
disclosure of contingent assets and liabilities. We regularly assess these estimates which primarily affect revenue recognition, 

88 

 
 
 
inventories, valuation of equity investments, goodwill arising out of business acquisitions, accrued liabilities, stock awards, and 
the valuation allowances associated with deferred tax assets. Actual results could differ from those estimates and such 
differences may be material to the consolidated financial statements.  

Segment Reporting 

We report two business segments, Performance Enzymes and Novel Biotherapeutics, which are based on our operating 

segments. Operating segments are defined as components of an enterprise about which separate financial information is 
available that is evaluated regularly by the chief operating decision maker or decision making group (“CODM”), in deciding 
how to allocate resources, and in assessing performance. Our CODM is our Chief Executive Officer. Our business segments are 
primarily based on our organizational structure and our operating results as used by our CODM in assessing performance and 
allocating resources for the Company. We do not allocate or evaluate assets by segment. 

The Novel Biotherapeutics segment focuses on new opportunities in the pharmaceutical industry to discover or improve 

novel biotherapeutic drug candidates that will target human diseases that are in need of improved therapeutic interventions. 
Similarly, we believe that we can deploy our platform technology to improve specific characteristics of a customer’s pre-
existing biotherapeutic drug candidate, such as its activity, stability, or immunogenicity. The Performance Enzymes segment 
consists of biocatalyst products and services with focus on pharmaceutical, food, molecular diagnostics, and other industrial 
markets. 

Foreign Currency Translation 

The USD is the functional currency for our operations outside the United States. Accordingly, non-monetary assets and 
liabilities originally acquired or assumed in other currencies are recorded in USD at the exchange rates in effect at the date they 
were acquired or assumed. Monetary assets and liabilities denominated in other currencies are translated into United States 
dollars at the exchange rates in effect at the balance sheet date. Translation adjustments are recorded in other expense in the 
consolidated statements of operations. Gains and losses realized from non-USD transactions, including intercompany balances 
not considered as permanent investments, denominated in currencies other than an entity’s functional currency are included in 
other expense in the accompanying consolidated statements of operations. 

Revenue Recognition 

Our revenues are derived primarily from product revenue and collaborative research and development agreements. The 

majority of our contracts with customers typically contain multiple products and services. We account for individual products 
and services separately if they are distinct-that is, if a product or service is separately identifiable from other items in the 
contract and if a customer can benefit from it on its own or with other resources that are readily available to the customer.  

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under our product revenue 

and collaborative research and development agreements, we perform the following steps: (i) identification of the promised 
goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, 
including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the 
constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated 
selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation. 

The majority of our collaborative contracts contain multiple revenue streams such as upfront and/or annual license fees, 

fees for research and development services, contingent milestone payments upon achievement of contractual criteria, and 
royalty fees based on the licensees' product revenue or usage, among others. We determine the stand-alone selling price (“SSP”) 
and allocate consideration to distinct performance obligations. Typically, we base our SSPs on our historical sales. If an SSP is 
not directly observable, then we estimate the SSP taking into consideration market conditions, forecasted sales, entity-specific 
factors and available information about the customer. We estimate the SSP for license rights by using historical information if 
licenses have been previously sold to customers and for new licenses, we consider multiple methods, including a discounted 
cash flow method which includes the following key assumptions: the development timelines, revenue forecasts, 
commercialization expenses, discount rate, and the probability of technical and regulatory success. 

We account for a contract with a customer when there is approval and commitment from both parties, the rights of the 
parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is 
probable. Non-cancellable purchase orders received from customers to deliver a specific quantity of product, when combined 
with our order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and 
constitute a contract with a customer. 

89 

 
We measure revenue based on the consideration specified in the contract with each customer, net of any sales incentives 

and taxes collected on behalf of government authorities. We recognize revenue in a manner that best depicts the transfer of 
promised goods or services to the customer, when control of the product or service is transferred to a customer. We make 
significant judgments when determining the appropriate timing of revenue recognition. 

The following is a description of principal activities from which we generate revenue: 

Product Revenue 

Product revenue consist of sales of biocatalysts, pharmaceutical intermediates and Codex® biocatalyst panels and kits. A 
majority of our product revenue is made pursuant to purchase orders or supply agreements and is recognized either at a point in 
time when the control of the product has been transferred to the customer typically upon shipment or over time as the product is 
manufactured because we have a right to payment from the customer under a binding, non-cancellable purchase order, and there 
is no alternate use of the product for us as it is specifically made for the customer’s use.  

Certain of our agreements provide options to customers which they can exercise at a future date, such as the option to 
purchase our product during the contract duration at discounted prices and an option to extend their contract, among others. In 
accounting for customer options, we determine whether an option is a material right and this requires us to exercise significant 
judgment. If a contract provides the customer an option to acquire additional goods or services at a discount that exceeds the 
range of discounts that we typically give for that product or service for the same class of customer, or if the option provides the 
customer certain additional goods or services for free, the option may be considered a material right. If the contract gives the 
customer the option to acquire additional goods or services at their normal SSPs, we would likely determine that the option is 
not a material right and, therefore, account for it as a separate performance obligation when the customer exercises the option. 
We primarily account for options which provide material rights using the alternative approach available pursuant to the 
applicable accounting guidance, as we concluded we meet the criteria for using the alternative approach. Therefore, the 
transaction price is calculated as the expected consideration to be received for all the goods and services we expect to provide 
under the contract. We update the transaction price for expected consideration, subject to constraint, each reporting period if our 
estimates of future goods to be ordered by customers change.  

Research and Development Revenues 

We perform research and development activities as specified in each respective customer agreement. We identify each 
performance obligation in our research and development agreements at contract inception. We allocate the consideration to each 
distinct performance obligation based on the estimated SSP of each performance obligation. Performance obligations included 
in our research and services agreements typically include research and development services for a specified term, periodic 
reports and small samples of enzyme produced. 

The majority of our research and development agreements are based on a contractual rate per dedicated project team 

working on the project. The underlying product that we develop for customers does not create an asset with an alternative use to 
us and the customer receives benefits as we perform the work towards completion. Thus, our performance obligations are 
generally satisfied over time as the service is performed. We utilize an appropriate method of measuring progress towards the 
completion of our performance obligations to determine the timing of revenue recognition. For each performance obligation 
that is satisfied over time, we recognize revenue using a single measure of progress, typically based on hours incurred. 

Our contracts frequently provide customers with rights to use or access our products or technology, along with other 
promises or performance obligations. We must first determine whether the license is distinct from other promises, such as our 
promise to manufacture a product. If we determine that the customer cannot benefit from the license without our manufacturing 
capability, the license will be accounted for as combined with the other performance obligations. If we determine that a license 
is distinct and has significant standalone functionality, we would recognize revenues from a functional license at a point in time 
when the license is transferred to the customer, and the customer can use and benefit from it. We estimate the SSP for license 
rights by using historical information if licenses have been previously sold to customers and for new licenses, we consider 
multiple methods, including a discounted cash flow method which includes the following key assumptions: the development 
timelines, revenue forecasts, commercialization expenses, discount rate, and the probability of technical and regulatory success. 
For licenses that have been previously sold to other customers, we use historical information to determine SSP. 

At the inception of each arrangement that includes variable consideration such as development milestone payments, we 

evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the 
transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the 
associated milestone value is included in the transaction price. Milestone payments that are not within our control or the 
licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The 
transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which we 

90 

 
recognize revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent 
reporting period, we re-evaluate the probability of achievement of such development milestones and any related constraint, and 
if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up 
basis, which would affect license, collaboration and other revenues and earnings in the period of adjustment. 

Our CodeEvolver® platform technology transfer collaboration agreements typically include license fees, upfront fees, and 

variable consideration in the form of milestone payments, and sales or usage-based royalties. We have recognized revenues 
from our platform technology transfer agreements over time as our customer learns to use our technology. 

For license agreements that include sales or usage-based royalty payments to us, we do not recognize revenue until the 
underlying sales of the product or usage has occurred. At the end of each reporting period, we estimate the royalty amount. We 
recognize revenue at the later of (i) when the related sale of the product occurs, or (ii) when the performance obligation to 
which some or all of the royalty has been allocated has been satisfied, or partially satisfied. 

Practical Expedients, Elections, and Exemptions 

We apply certain practical expedients available which permit us not to adjust the amount of consideration for the effects of 

a significant financing component if, at contract inception, the expected period between the transfer of promised goods or 
services and customer payment is one year or less. 

We perform monthly services under our research and development agreements, and we use a practical expedient permitting 
us to recognize revenue at the same time that we have the right to invoice our customer for monthly services completed to date. 

We have elected to treat shipping and handling activities as fulfillment costs. 

We have elected to record revenue net of sales and other similar taxes. 

Contract Assets  

Contract assets include amounts related to our contractual right to consideration for completed performance obligations not 

yet invoiced. Contract assets are reclassified to receivables when the rights become unconditional.  

Contract Liabilities 

Contract liabilities are recorded as deferred revenues and include payments received in advance of performance under the 
contract. Contract liabilities are realized when the development services are provided to the customer or control of the products 
has been transferred to the customer. A portion of our contract liabilities relate to supply arrangements that contain material 
rights that are recognized using the alternative method, under which the aggregate amount invoiced to the customer for shipped 
products, including contractual fees, is higher than the amount of revenue recognized based on the transaction price allocated to 
the shipped products. 

Contract Costs 

We recognize a non-current asset for the incremental costs of obtaining a contract with a customer if the entity expects to 

recover such costs. Incremental costs are costs that would not have been incurred if the contract had not been obtained. 
Examples of contract costs are commissions paid to sales personnel. We do not typically incur significant incremental costs 
because the compensation of our salespeople is not based on contracts closed but on a mixture of company goals, individual 
goals, and sales goals. If a commission paid is directly related to obtaining a specific contract, our policy is to capitalize and 
amortize such costs on a systematic basis, consistent with the pattern of transfer of the good or service to which the asset 
relates. Contract costs are reported in other non-current assets. 

Cost of Product Revenue 

Cost of product revenue comprises both internal and third party fixed and variable costs including materials and supplies, 
labor, facilities, and other overhead costs associated with our product sales. Shipping costs are included in our cost of product 
revenue. Such charges were not significant in any of the periods presented. 

Fulfillment costs, such as shipping and handling, are recognized at a point in time and are included in cost of product sales. 

Cost of Research and Development Services 

Cost of research and development services related to services under research and development agreements approximate the 

research funding over the term of the respective agreements and is included in research and development expense. Costs of 

91 

 
services provided under license and platform technology transfer agreements are included in research and development 
expenses and are expensed in the periods in which such costs are incurred. 

Research and Development Expenses 

Research and development expenses consist of costs incurred for internal projects and partner-funded collaborative 

research and development activities, as well as license and platform technology transfer agreements, as mentioned above. These 
costs include our direct and research-related overhead expenses, which include salaries and other personnel-related expenses 
(including stock-based compensation), occupancy-related costs, supplies, and depreciation of facilities and laboratory 
equipment, as well as external costs, and are expensed as incurred. Costs to acquire technologies that are utilized in research 
and development and that have no alternative future use are expensed when incurred. 

Advertising 

Advertising costs are expensed as incurred and included in selling, general and administrative expenses in the consolidated 

statements of operations. Advertising costs were $0.3 million, $0.3 million and $0.5 million in the years ended December 31, 
2021, 2020 and 2019, respectively. 

Stock-Based Compensation 

We use the Black-Scholes-Merton option pricing model to estimate the fair value of options granted under our equity 
incentive plans. The Black-Scholes-Merton option pricing model requires the use of assumptions, including the expected term 
of the award and the expected stock price volatility. The expected term is based on historical exercise behavior on similar 
awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. We use 
historical volatility to estimate expected stock price volatility. The risk-free rate assumption is based on United States Treasury 
instruments whose terms are consistent with the expected term of the stock options. The expected dividend assumption is based 
on our history and expectation of dividend payouts. 

Restricted Stock Units (“RSUs"), Restricted Stock Awards (“RSAs”) and performance-contingent restricted stock units 
(“PSUs”) are measured based on the fair market values of the underlying stock on the dates of grant. Performance based options 
(“PBOs”) are measured using Black-Scholes-Merton option pricing model. The vesting of PBOs and PSUs awarded is 
conditioned upon the attainment of one or more performance objectives over a specified period and upon continued 
employment through the applicable vesting date. At the end of the performance period, shares of stock subject to the PBOs and 
PSUs vest based upon both the level of achievement of performance objectives within the performance period and continued 
employment through the applicable vesting date. 

Stock-based compensation expense is calculated based on awards ultimately expected to vest and is reduced for estimated 
forfeitures at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. 
The estimated annual forfeiture rates for stock options, RSUs, PSUs, PBOs, and RSAs are based on historical forfeiture 
experience. 

The estimated fair value of stock options, RSUs and RSAs are expensed on a straight-line basis over the vesting term of the 
grant and the estimated fair value of PSUs and PBOs are expensed using an accelerated method over the term of the award once 
management has determined that it is probable that the performance objective will be achieved. Compensation expense is 
recorded over the requisite service period based on management's best estimate as to whether it is probable that the shares 
awarded are expected to vest. Management assesses the probability of the performance milestones being met on a continuous 
basis. 

Cash and Cash Equivalents 

We consider all highly liquid investments with maturity dates of three months or less at the date of purchase to be cash 
equivalents. Cash and cash equivalents consist of cash on deposit with banks and money market funds. The majority of cash 
and cash equivalents is maintained with major financial institutions in the United States. Deposits with these financial 
institutions may exceed the amount of insurance provided on such deposits.  

Restricted Cash 

In 2016, we began the process of liquidating our Indian subsidiary. The local legal requirements for liquidation required us 

to maintain our subsidiary's cash balance in an account managed by a legal trustee to satisfy our financial obligations. This 
balance is recorded as current restricted cash on the consolidated balance sheets of $0.6 million as of December 31, 2021 and 
2020. 

92 

 
Pursuant to the terms of a lease agreement for our Redwood City, CA facilities, we obtained a letter of credit collateralized 
by cash deposit balances of $1.1 million as of December 31, 2021 and 2020. Pursuant to the terms of our new lease agreement 
for our San Carlos, CA facility, we also obtained a letter of credit collateralized by cash deposit balances of $0.5 million as 
of December 31, 2021. These cash deposits balances are recorded as non-current restricted cash on the consolidated balance 
sheets. For additional information, see Note 13, “Commitments and Contingencies”.  

Fair Value Measurements 

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly 

transaction between market participants at the measurement date. In determining fair value, we utilize valuation techniques that 
maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and we consider 
counterparty credit risk in our assessment of fair value. Carrying amounts of financial instruments, including cash equivalents, 
accounts receivable, accounts payable, and accrued liabilities, approximate their fair values as of the balance sheet dates 
because of their short maturities. 

The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data 

obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant 
assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value 
hierarchy consists of three broad levels, giving the highest priority to unadjusted quoted prices in active markets for identical 
assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value 
hierarchy are described below: 

•  Level 1: Inputs that are unadjusted, quoted prices in active markets for identical assets or liabilities at the 

measurement date. 

•  Level 2: Inputs that are either directly or indirectly observable for the asset or liability through correlation 

with market data at the measurement date and for the duration of the instrument’s anticipated life.  

•  Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the 
fair value of the assets or liabilities and which reflect management’s best estimate of what market participants would 
use in pricing the asset or liability at the measurement date. 

Concentrations of Credit Risk 

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and 

cash equivalents, accounts receivable and unbilled receivables, contract assets, non-marketable securities, and restricted cash. 
Cash that is not required for immediate operating needs is invested principally in money market funds. Cash and cash 
equivalents are invested through banks and other financial institutions in the United States, India, and the Netherlands. Such 
deposits in those countries may be in excess of insured limits. The Company has not experienced material losses on its deposits 
of cash and cash equivalents. 

We perform ongoing credit evaluations of our customer's financial condition whenever deemed necessary. We maintain an 

allowance for doubtful accounts based on the expected collectability of all financial assets, which takes into consideration an 
analysis of historical bad debts, specific customer creditworthiness and current economic trends. As of December 31, 2021, we 
had one customer that accounted for 62% of our accounts receivable balance. As of December 31, 2020, three customers 
accounted for 70% of our accounts receivable balance. We believe the accounts receivable balances from our largest customers 
do not represent a significant credit risk, based on cash flow forecasts, balance sheet analysis, and past collection experience. 

Financial Assets and Allowances 

We currently sell enzymes primarily to pharmaceutical and fine chemicals companies throughout the world by the 

extension of trade credit terms based on an assessment of each customer's financial condition. Trade credit terms are generally 
offered without collateral and may include an insignificant discount for prompt payment for specific customers. To manage our 
credit exposure, we perform ongoing evaluations of our customers' financial conditions. In addition, accounts receivable 
include amounts owed to us under our collaborative research and development agreements.  

We recognize accounts receivable at invoiced amounts and we maintain a valuation allowance for credit losses using an 
impairment model (known as the “current expected credit loss model” or “CECL”) based on estimates and forecasts of future 
conditions requiring recognition of a lifetime of expected credit losses at inception on our financing receivables measured at 
amortized costs which consisted of accounts receivable, contract assets, and unbilled receivables. We have determined that our 
financing receivables share similar risk characteristics including: (i) customer origination in the pharmaceutical and fine 
chemicals industry, (ii) similar historical credit loss pattern of customers (iii) no meaningful trade receivable differences in 
terms, (iv) similar historical credit loss experience and (v) our belief that the composition of certain assets are comparable to 

93 

 
our historical portfolio used to develop loss history. As a result, we measured the allowance for credit loss (“ACL”) on a 
collective basis. Our ACL methodology considers how long the asset has been past due, the financial condition of the 
customers, which includes ongoing quarterly evaluations and assessments of changes in customer credit ratings, and other 
market data that we believe are relevant to the collectability of the assets. Nearly all financing receivables are due from 
customers that are highly rated by major rating agencies and have a long history of no credit loss. We derive our ACL by 
establishing an impairment rate attributable to assets not yet identified as impaired. 

We derive our ACL by initially relying on our historical financing receivable loss rate which contemplates the full 
contractual life of the assets sharing similar risk characteristics, adjusted to reflect (i) the extent to which we have determined 
current conditions differ from the conditions that existed for the period over which historical loss information was evaluated 
and (ii) by taking into consideration the changes in certain macroeconomic historical and forecasted information. We apply the 
ACL to past due financing receivables and record charges to the ACL as a provision to credit loss expense in the Statement of 
Operations. Financing receivables we identify as uncollectible are also charged against the ACL. We adjust the impairment rate 
to reflect the extent to which we have determined current conditions differ from the conditions that existed for the period over 
which historical loss information was evaluated. Adjustments to historical loss information may be qualitative or quantitative in 
nature and reflect changes related to relevant data. 

Unbilled Receivable 

The timing of revenue recognition may differ from the timing of invoicing to our customers. When we satisfy (or partially 

satisfy) a performance obligation, prior to being able to invoice the customer, we recognize an unbilled receivable when the 
right to consideration is unconditional.  

Inventories 

Inventories are stated at the lower of cost or net realizable value. Cost is determined using a weighted-average approach, 

assuming full absorption of direct and indirect manufacturing costs, or based on cost of purchasing from our vendors. If 
inventory costs exceed expected net realizable value due to obsolescence or lack of demand, valuation adjustments are recorded 
for the difference between the cost and the expected net realizable value. 

Concentrations of Supply Risk 

We rely on a limited number of suppliers for our products. We believe that other vendors would be able to provide similar 

products; however, the qualification of such vendors may require substantial start-up time. In order to mitigate any adverse 
impacts from a disruption of supply, we attempt to maintain an adequate supply of critical single-sourced materials. For certain 
materials, our vendors maintain a supply for us. We outsource the large scale manufacturing of our products to contract 
manufacturers with facilities in Austria and Italy. 

Property and Equipment 

Property, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization 

calculated using the straight-line method over their estimated useful lives as follows: 

Asset classification 
Laboratory equipment 
Computer equipment and software 
Office equipment and furniture 
Leasehold improvements 

Estimated useful life 
5 years 
3 to 5 years 
5 years 
Lesser of useful life or lease term 

Property and equipment classified as construction in process includes equipment that has been received but not yet placed 

in service. Normal repairs and maintenance costs are expensed as incurred. 

Impairment of Long-Lived Assets 

We have not identified property and equipment by segment since these assets are shared or commingled. We evaluate the 
carrying values of long-lived assets, which include property and equipment and right-of-use assets, whenever events, changes in 
business circumstances or our planned use of long-lived assets indicate that their carrying amounts may not be fully recoverable 
or that their useful lives are no longer appropriate. If these facts and circumstances exist, we assess for recovery by comparing 
the carrying values of long-lived assets with their future net undiscounted cash flows. If the comparison indicates that 
impairment exists, long-lived assets are written down to their respective fair values based on discounted cash flows. Significant 

94 

 
 
 
 
 
 
 
management judgment is required in the forecast of future operating results that are used in the preparation of unexpected 
undiscounted cash flows. 

As of December 31, 2021 and 2020, there were no events or changes in circumstances which indicated that the carrying 

amount of our asset group might not be recoverable. No impairment charges for long-lived assets were recorded during the 
years ended December 31, 2021, 2020 and 2019. 

Investment in Non-Marketable Securities 

Investment in Non-Marketable Equity Securities 

We measure investments in non-marketable equity securities without a readily determinable fair value using a measurement 

alternative that measures these securities at the cost method minus impairment, if any, plus or minus changes resulting from 
observable price changes on a non-recurring basis. Gains and losses on these securities are recognized in other income 
(expense), net. 

Investment in Non-Marketable Debt Securities 

We measure available-for-sale investments in non-marketable debt at fair value. Unrealized gains and losses on these 

securities are recognized in other comprehensive income until realized. Non-marketable debt securities are classified as 
available-for-sale securities. 

We classify non-marketable debt securities as Level 3 in the fair value hierarchy because we estimate the fair value based 
on a qualitative analysis using the most recent observable transaction price and other significant unobservable inputs including 
volatility, rights, and obligations of the securities we hold. Significant changes to the unobservable inputs may result in a 
significantly higher or lower fair value estimate. We may value these securities based on significant recent arms-length 
transactions with sophisticated non-strategic unrelated new investors. 

We evaluate both equity and debt securities for impairment when circumstances indicate that we may not be able to recover 
the carrying value. We may impair these securities and establish an allowance for a credit loss when we determine that there has 
been an “other-than-temporary” decline in estimated fair value of the debt or equity security compared to its carrying value. We 
calculate the estimated fair value of these securities using information from the investee, which may include: 

• 

• 

• 

• 

• 

• 

Audited and unaudited financial statements; 

Projected technological developments of the company; 

Projected ability of the company to service its debt obligations; 

If a deemed liquidation event were to occur; 

Current fundraising transactions; 

Current ability of the company to raise additional financing if needed; 

• 
company; 

Changes in the economic environment which may have a material impact on the operating results of the 

• 

• 

• 

Contractual rights, obligations or restrictions associated with the investment; and 

Other factors deemed relevant by our management to assess valuation. 

The valuation may be reduced if the company's potential has deteriorated significantly. If the factors that led 

to a reduction in valuation are overcome, the valuation may be readjusted. 

Goodwill 

Goodwill represents the excess of the consideration transferred over the fair value of net assets of businesses acquired and 

is assigned to reporting units. We test goodwill for impairment considering amongst other things, whether there have been 
sustained declines in our share price. If we conclude it is more likely than not that the fair value of a reporting unit is less than 
its carrying amount, a quantitative fair value test is performed. We manage our business as two reporting units and we test 
goodwill for impairment at the reporting unit level. We allocated goodwill to the two reporting units using a relative fair value 
allocation methodology that primarily relied on our estimates of revenue and future earnings for each reporting unit. Using the 
relative fair value allocation methodology, we have determined that approximately $2.4 million, or 76%, of the goodwill is 
allocated to the Performance Enzymes segment and $0.8 million, or 24%, is assigned to the Novel Biotherapeutics segment.  

95 

 
We test goodwill for impairment annually on a reporting unit basis, on the last day of the fourth fiscal quarter, and between 

annual tests if events and circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its 
carrying amount. The annual impairment test is completed using either: a qualitative “Step 0” assessment based on reviewing 
relevant events and circumstances; or a quantitative “Step 1” assessment, which determines the fair value of the reporting unit. 
To the extent the carrying amount of a reporting unit is less than its estimated fair value, an impairment charge is recorded. 
Using the relative fair value allocation methodology for assets and liabilities used in both of our reporting units, we compare the 
allocated carrying amount of each reporting unit’s net assets and the assigned goodwill to its fair value. If the fair value of the 
reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. Any excess of the 
reporting unit’s carrying amount of goodwill over its fair value is recognized as an impairment. During 2021, 2020 and 2019, 
we did not record impairment charges related to goodwill. 

Lease Accounting 

We determine if an arrangement is a lease at inception. Where an arrangement is a lease, we determine if it is an operating 

lease or a finance lease. At lease commencement, we record a lease liability and ROU asset. Lease liabilities represent the 
present value of our future lease payments over the expected lease term which includes options to extend or terminate the lease 
when it is reasonably certain those options will be exercised. The present value of our lease liability is determined using our 
incremental collateralized borrowing rate at lease inception. ROU assets represent our right to control the use of the leased asset 
during the lease and are recognized in an amount equal to the lease liability for leases with an initial term greater than 12 
months. Over the lease term, we use the effective interest rate method to account for the lease liability as lease payments are 
made and the ROU asset is amortized to the consolidated statement of operations in a manner that results in straight-line 
expense recognition. We do not apply lease recognition requirements for short-term leases. Instead, we recognize payments 
related to these arrangements in the consolidated statement of operations as lease costs on a straight-line basis over the lease 
term. 

Income Taxes 

We use the liability method of accounting for income taxes, whereby deferred tax asset or liability account balances are 
calculated at the balance sheet date using current tax laws and rates in effect for the year in which the differences are expected 
to affect taxable income. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that 
will more likely than not be realized. 

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These 
estimates and judgments occur in the calculation of tax credits, benefits and deductions and in the calculation of certain tax 
assets and liabilities, which arise from differences in the timing of recognition of revenues and expenses for tax and financial 
statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in a 
subsequent period. 

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all 
of the deferred tax assets will be realized on a jurisdiction by jurisdiction basis. The ultimate realization of deferred tax assets is 
dependent upon the generation of taxable income in the future. We have recorded a valuation allowance against these deferred 
tax assets in jurisdictions where ultimate realization of deferred tax assets is more likely than not to occur. As of December 31, 
2021, we maintain a full valuation allowance in all jurisdictions against the net deferred tax assets as we believe that it is more 
likely than not that the majority of deferred tax assets will not be realized. 

We make estimates and judgments about our future taxable income that are based on assumptions that are consistent with 

our plans and estimates. Should the actual amounts differ from our estimates, the amount of our valuation allowance may be 
materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded in the statements of 
operations for the periods in which the adjustment is determined to be required. 

We account for uncertainty in income taxes as required by the provisions of ASU 2009-06, Income Taxes (Topic 740) 
Implementation Guidance on Accounting for Uncertainty in Income Taxes and Disclosure Amendments for Nonpublic Entities, 
which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The first step 
is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely 
than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The 
second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon 
ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires us to determine the 
probability of various possible outcomes. We consider many factors when evaluating and estimating our tax positions and tax 
benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes. 

The Tax Reform Act of 1986 and similar state provisions limit the use of net operating loss (“NOL”) carryforwards in 

96 

 
certain situations where equity transactions result in a change of ownership as defined by Internal Revenue Code 
Section 382. In the event we should experience such a change of ownership, utilization of our federal and state NOL 
carryforwards could be limited. 

Accounting Pronouncements 

Recently adopted accounting pronouncements 

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income 
Taxes which is intended to simplify various aspects related to accounting for income taxes. The standard is effective for fiscal 
years, and interim periods within those years, beginning after December 15, 2020, with early adoption permitted. The standard 
was adopted beginning January 1, 2021 on a retrospective basis. The adoption of ASU 2019-12 did not have an impact on our 
consolidated financial statements and related disclosures. 

In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements. ASU 2020-10 provides amendments to a 
wide variety of topics in the FASB’s Accounting Standards Codification, which applies to all reporting entities within the scope 
of the affected accounting guidance. We adopted the standard on January 1, 2021 and it had no impact on our consolidated 
financial statements and related disclosures. 

Recently issued accounting pronouncements not yet adopted 

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are 
adopted by us as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued 
standards that are not yet effective will not have a material impact on our consolidated financial statements upon adoption. 

In May 2021, FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments 
(Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own 
Equity (Subtopic 815-40), Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified 
Written Call Options, a consensus of the Emerging Issues Task Force. The standard establishes a principles-based framework in 
accounting for modifications of freestanding equity-classified written call options on the basis of the economic substance of the 
underlying transaction. The standard also requires incremental financial statement disclosures. The standard affects entities that 
present earnings per share in accordance with the guidance in Topic 260, Earnings Per Share. The standard is effective for fiscal 
years beginning after December 15, 2021, including interim periods within those fiscal years with early adoption is permitted 
by applying the standard as of the beginning of the fiscal year that includes that interim period. The standard may be adopted 
prospectively for modifications or exchanges occurring on or after the effective date. We have evaluated that the adoption of 
ASU 2021-04 will not have an impact on our consolidated financial statements and related disclosures. 

In August 2020, FASB issued ASU No 2020-06 Debt—Debt with Conversion and Other Options (Subtopic 470-20) and 

Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) No. 2020-06 August 2020 Accounting for 
Convertible Instruments and Contracts in an Entity’s Own Equity, to reduce the complexity and to simplify the accounting for 
convertible debt instruments and convertible preferred stock, and the derivatives scope exception for contracts in an entity's 
own equity. In addition, the guidance on calculating diluted earnings per share has been simplified and made more internally 
consistent. The standard is effective the for fiscal years beginning after December 15, 2021, and interim periods within those 
fiscal years, with early adoption permitted for fiscal periods beginning after December 15, 2020. The standard may be adopted 
on a modified retrospective or fully retrospective method of transition and on adoption, entities may irrevocably elect the fair 
value option in accordance with Subtopic 825-10, Financial Instruments—Overall, for any financial instrument that is a 
convertible security. We have evaluated that the adoption of ASU 2020-06 will not have an impact on our consolidated financial 
statements and related disclosures. 

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of 

Reference Rate Reform on Financial Reporting. The standard provides optional expedients and exceptions for applying GAAP 
to contracts, hedging relationships, and other transactions in which the reference LIBOR or another reference rate are expected 
to be discontinued as a result of the Reference Rate Reform. The standard is effective for all entities. The standard may be 
adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 through 
December 31, 2022, on a prospective basis. We will evaluate transactions or contract modifications occurring as a result of 
reference rate reform and determine whether to elect the optional expedients for contract modification; however, we believe that 
the adoption of ASU 2020-04 will have no significant impact on our consolidated financial statements and related disclosures.

We recognize accounts receivable when we have an unconditional right to recognize revenue and have issued an invoice to 

the customer. Our payment terms are generally between 30 and 90 days. We recognize unbilled receivables when we have an 
unconditional right to recognize revenue and have not issued an invoice to our customer. Unbilled receivables are transferred to 
accounts receivable on issuance of an invoice. Unbilled receivables are classified separately on the consolidated balance sheets 
as assets. We maintain a valuation allowance on accounts receivables and unbilled receivables. 

Contract assets represent our right to recognize revenue for custom products with no alternate use and under binding non-

cancellable contracts and are largely related to our procurement of product. We recognize contract assets when we have a 
conditional right to recognize revenue. The transfer of control of certain of products occurs in advance of the invoicing process, 
which generates contract assets. In addition, we recognize a contract asset related to milestones not eligible for royalty 
accounting when we assess it is probable of being achieved and there will be no significant reversal of cumulative revenues. 
Contract assets are classified separately on the consolidated balance sheets as an asset and transferred to accounts receivables 
when our rights to payment become unconditional.  

Contract liabilities, or deferred revenue, represent our obligation to transfer a product or service to the customer, and for 
which we have received consideration from the customer. We recognize a contract liability when we receive advance customer 
payments under development  agreements  for research and development  services, upfront license payments,  and from upfront 
customer  payments  received  under  product  supply  agreements.  Contract  liabilities  are  classified  as  a  liability  on  the 
consolidated balance sheet. 

Contract costs relate to incremental costs of obtaining a contract with a customer. Contract costs are amortized along with 

the associated revenue over the term of the contract.  

During the years ended December 31, 2021, 2020 and 2019, we had no asset impairment charges related to contract assets.  

We recognized the following revenues (in thousands): 

Revenue recognized in the period for: 
Amounts included in contract liabilities at the beginning of the period: 
     Performance obligations satisfied 
Changes in the period: 

Changes in the estimated transaction price allocated to performance 
obligations satisfied in prior periods

Note 4. Net Loss per Share 

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock 
outstanding, less restricted stock awards (“RSAs”) subject to forfeiture. Diluted net loss per share is computed by dividing net 
loss by the weighted-average number of shares of common stock shares outstanding, less RSAs subject to forfeiture, plus all 
additional common shares that would have been outstanding, assuming dilutive potential common stock shares had been issued 
for other dilutive securities. For all periods presented, diluted and basic net loss per share are identical since potential common 
stock shares are excluded from the calculation, as their effect was anti-dilutive. 

Anti-Dilutive Securities 

In periods of net loss, the weighted average number of shares outstanding, prior to the application of the treasury stock 
method, excludes potentially dilutive securities from the computation of diluted net loss per common share because including 
such shares would have an anti-dilutive effect.  

The following shares were not considered in the computation of diluted net loss per share because their effect was anti-

dilutive (in thousands):

GSK Platform Technology Transfer, Collaboration and License Agreement 

In July 2014, we entered into a CodeEvolver® protein engineering platform technology transfer collaboration and license 
agreement (the “GSK CodeEvolver® Agreement”) with GSK. Pursuant to the terms of the agreement, we granted GSK a non-
exclusive license to use the CodeEvolver® protein engineering platform technology to develop novel enzymes for use in the 
manufacture of GSK's pharmaceutical and health care products. We completed the transfer of the CodeEvolver® protein 
engineering platform technology to GSK in April 2016 and all revenues relating to the technology transfer have been 
recognized as of April 2016. Depending upon GSK's successful application of the licensed technology, we have the potential to 
receive additional contingent payments that range from $5.75 million to $38.5 million per project.  

In 2019, we received a $2.0 million milestone payment relating to the advancement of an enzyme developed by GSK using 
our CodeEvolver® protein engineering platform technology. In 2021, we received two additional milestone payments from GSK 
under the agreement. We recognized research and development revenue of $4.3 million, nil, and $2.0 million in the years ended 
December 31, 2021, 2020, and 2019, respectively.

Merck Platform Technology Transfer and License Agreement 

In August 2015, we entered into a CodeEvolver® platform technology transfer collaboration and license agreement (the 
“Merck CodeEvolver® Agreement”) with Merck, Sharp & Dohme (“Merck”) which allows Merck to use the CodeEvolver® 
protein engineering technology platform in the field of human and animal healthcare. In 2016, we completed the final phase in 
the transfer of CodeEvolver® technology to Merck under the Merck CodeEvolver® Agreement.  

We recognized research and development revenues of $0.6 million, $3.1 million, and $4.0 million in the years ended 

December 31, 2021, 2020 and 2019, respectively, for various research projects under our collaborative arrangement. 

We have the potential to receive payments of up to a maximum of $15.0 million for each commercial active pharmaceutical 

ingredient (“API”) that is manufactured by Merck using one or more novel enzymes developed by Merck using the 
CodeEvolver® protein engineering technology platform. The API payments, which are currently not recognized in revenue, are 
based on the quantity of API developed and manufactured by Merck and will be recognized as usage-based royalties. 

In October 2018, we entered into an amendment to the Merck CodeEvolver® Agreement which amended certain licensing 
provisions and one exhibit. In January 2019, we amended the Merck CodeEvolver® Agreement to install certain CodeEvolver® 
protein engineering technology upgrades into Merck’s platform license installation and maintain those upgrades for a multi-year 
term expiring in January 2022. The license installation was completed in 2019 and we recognized $0.9 million as license fee 
revenue accordingly under the amendment. We recognized $0.1 million, $0.1 million and $0.9 million in research and 
development revenues under the terms of the amendment in 2021, 2020 and 2019 respectively.  

Merck Sitagliptin Catalyst Supply Agreement 

In February 2012, we entered into a five-year Sitagliptin Catalyst Supply Agreement (“Sitagliptin Supply Agreement”) 
with Merck whereby Merck may obtain commercial scale enzyme for use in the manufacture of Januvia®, its product based on 
the active ingredient Sitagliptin. In December 2015, Merck exercised its options under the terms of the Sitagliptin Catalyst 
Supply Agreement to extend the agreement for an additional five years through February 2022. In September 2021, the 
Sitagliptin Catalyst Supply Agreement was amended to extend the agreement through December 2026.  

Effective as of January 2016, we and Merck amended the Sitagliptin Supply Agreement to prospectively provide for 
variable pricing based on the cumulative volume of sitagliptin enzyme purchased by Merck. We have determined that the 
variable pricing, which provides a discount based on the cumulative volume of Sitagliptin catalyst purchased by Merck, 
provides Merck material rights and we are recognizing product revenues over time using the alternative method. Under the 
alternative approach, we estimate the total expected consideration and allocate it proportionately with the expected sales. 

Pursuant to the terms of the Sitagliptin Supply Agreement, Merck may purchase supply of sitagliptin enzyme from us for a 
fee based on contractually stated prices. We recognized $9.8 million, $13.4 million and $15.1 million in product revenue under 
this contract for the years ended December 31, 2021, 2020 and 2019, respectively. Revenues recognized by us under the 
Sitagliptin Supply Agreement comprised 9%, 19%, and 22% of our total revenues for the years ended December 31, 2021, 2020 
and 2019, respectively. 

As of December 31, 2021, we recorded revenue of $2.8 million from sitagliptin enzyme sales that were recognized over 

time based on the progress of the manufacturing process. These products will be shipped within the six months period 
following the end of the quarter.  

Enzyme Supply Agreement 

In November 2016, we entered into a supply agreement whereby our customer may purchase quantities of one of our 
proprietary enzymes for use in its commercial manufacture of a product. Pursuant to the supply agreement, we received an 
upfront payment in December 2016 which was recorded as deferred revenue. Such upfront payment will be recognized over the 
period of the supply agreement as the customer purchases our proprietary enzyme. We additionally have determined that the 
volume discounts under the supply agreement provide the customer material rights and we are recognizing revenues using the 
alternative method. As of December 31, 2021 and 2020, we had deferred revenue balances from the supply agreement of $2.6 
million and $2.0 million. 

Research and Development Agreement 

In March 2017, we entered into a multi-year research and development services agreement with Tate & Lyle Ingredients 
Americas LLC (“Tate & Lyle”) to develop enzymes for use in the manufacture of Tate & Lyle’s zero-calorie TASTEVA® M 
Stevia sweetener. Under the agreement, we received an upfront payment which was recognized ratably over the maximum term 
of the service period of 21 months.  

101 

 
Commercial Agreement 

In April 2019, we entered into a multi-year commercial agreement with Tate & Lyle under which Tate & Lyle has received 

an exclusive license to use a suite of Codexis novel performance enzymes in the manufacture of Tate & Lyle’s zero-calorie 
stevia sweetener, TASTEVA® M, and other stevia products. Under the agreement, we will supply Tate & Lyle with its 
requirements for these enzymes over a multiple year period and receive royalties on stevia products. In November 2020, we 
amended the commercial agreement based on Tate & Lyle's intent to use a specific Codexis novel performance enzyme in its 
production of TASTEVA® M Stevia Sweetener and became eligible to receive milestone payments of up to $1.1 million. In the 
fourth quarter of 2020, we became eligible to receive a milestone payment of $0.4 million which we subsequently received in 
February 2021.  

Global Development, Option and License Agreement and Strategic Collaboration Agreement 

In October 2017, we entered into the Nestlé License Agreement with Nestlé Health Science and, solely for the purpose of 

the integration and the dispute resolution clauses of the Nestlé License Agreement, Nestlé Health Science S.A., to advance 
CDX-6114, our enzyme biotherapeutic product candidate for the potential treatment of PKU. 

We received an upfront cash payment of $14.0 million in 2017 upon the execution of the Nestlé License Agreement, a $4.0 
million milestone payment received in 2018 after dosing the first subjects in a first-in-human Phase 1a dose-escalation trial with 
CDX-6114, and a $1.0 million milestone payment received in 2019 upon achievement of a milestone relating to formulation of 
CDX-6114. The upfront payment and the variable consideration relating to the progress payment of $4.0 million and a 
milestone payment of $1.0 million were recognized over time as the development work was performed. Revenue was 
recognized using a single measure of progress that depicted our performance in transferring control of the services, which was 
based on the ratio of level of effort incurred to date compared to the total estimated level of effort required to complete all 
performance obligations under the agreement. We recognized nil, $13 thousand and $1.9 million in research and development 
revenue in 2021, 2020 and 2019, respectively.  

In January 2019, we received notice from the FDA that it had completed its review of our IND for CDX-6114 and 

concluded that we may proceed with the proposed Phase 1b multiple ascending dose study in healthy volunteers in the United 
States. In February 2019, Nestlé Health Science exercised its option to obtain an exclusive, worldwide, royalty-bearing, sub-
licensable license for the global development and commercialization of CDX-6114 for the management of PKU and made an 
option payment of $3.0 million which we recognized as research and development revenue in 2019. Upon exercising its option, 
Nestlé Health Science assumed all responsibilities for future clinical development and commercialization of CDX-6114. We are 
also eligible to receive payments from Nestlé Health Science under the Nestlé License Agreement that include (i) development 
and approval milestones of up to $85.0 million, (ii) sales-based milestones of up to $250.0 million in the aggregate, which 
aggregate amount is achievable if net sales exceed $1.0 billion in a single year, and (iii) tiered royalties, at percentages ranging 
from the mid-single digits to low double-digits of net sales of product. 

In October 2017, we entered into the Nestlé SCA pursuant to which we and Nestlé Health Science are collaborating to 
leverage the CodeEvolver® protein engineering technology platform to develop novel enzymes for Nestlé Health Science’s 
established Consumer Care and Medical Nutrition business areas. The term of the Nestlé SCA has been extended through 
December 2022. 

In January 2020, we entered into a development agreement with Nestlé Health Science pursuant to which we and Nestlé 

Health Science are collaborating to advance a lead candidate, CDX-7108, targeting a gastrointestinal disorder discovered 
through our Nestlé SCA into preclinical and early clinical studies. During 2021, we, together with Nestlé Health Science, 
continued to advance CDX-7108 towards initiation of a Phase 1 clinical trial with the first subject being dosed in November 
2021.  

Under the Nestlé SCA and the development agreement, we recognized $6.9 million, $7.9 million and $5.4 million in 

research and development revenue for the years ended December 31, 2021, 2020 and 2019, respectively. 

Strategic Collaboration Agreement 

In April 2018, we entered into the Porton Agreement with Porton to license key elements of our biocatalyst technology for 
use in Porton’s global custom intermediate and API development and manufacturing business. Under the Porton Agreement, we 
are eligible to receive annual collaboration fees and research and development revenues. We received initial collaboration 
payments of $0.5 million and $0.5 million within 30 days of the effective date and on the first anniversary of the effective date 
of the Porton Agreement, respectively. We also received annual collaboration payments of $1.0 million each during the first 
through third anniversaries of the effective date of the Porton Agreement and are eligible to receive $1.0 million on the fourth 
anniversary of the effective date of the Porton Agreement. We completed the technical transfer in the fourth quarter of 2018 and 

102 

 
recognized the related revenue in 2018. We recognized revenue related to the functional license provided to Porton at a point in 
time when control of the license was transferred to the customer. We recognized research and development revenue related to 
the Porton Agreement of $1.1 million, $1.1 million and nil in the years ended December 31, 2021, 2020 and 2019, respectively. 

Platform Technology Transfer and License Agreement 

In May 2019, we entered into a Platform Technology Transfer and License Agreement (the “Novartis CodeEvolver® 
Agreement”) with Novartis. The Agreement allows Novartis to use our proprietary CodeEvolver® protein engineering platform 
technology in the field of human healthcare. In July 2021, we announced the completion of the technology transfer period 
during which we transferred our CodeEvolver® protein engineering platform technology to Novartis (the “Technology Transfer 
Period”). As a part of this technology transfer, the Company provided to Novartis our proprietary enzymes, proprietary protein 
engineering protocols and methods, and proprietary software algorithms. In addition, our teams and Novartis scientists 
participated in technology training sessions and collaborative research projects at our laboratories in Redwood City, California 
and at a designated Novartis laboratory in Basel, Switzerland. Novartis has now installed the CodeEvolver® protein engineering 
platform technology at its designated laboratory. 

Pursuant to the agreement, we received an upfront payment of $5.0 million shortly after the effective date of the Novartis 
CodeEvolver® Agreement. We completed the second technology milestone transfer under the agreement in 2020 and received a  
milestone payment of $4.0 million. We have also received an aggregate of $5.0 million for the completion of the third 
technology milestone in 2021 In consideration for the continued disclosure and license of improvements to the technology and 
materials during a multi-year period that began on the conclusion of the Technology Transfer Period (“Improvements Term”), 
Novartis will pay Codexis annual payments over four years which amount to an additional $8.0 million in aggregate. The 
Company also has the potential to receive quantity-dependent, usage payments for each API that is manufactured by Novartis 
using one or more enzymes that have been developed or are in development using the CodeEvolver® protein engineering 
platform technology during the period that began on the conclusion of the Technology Transfer Period and ends on the 
expiration date of the last to expire licensed patent. Revenue for the combined initial license and technology transfer 
performance obligation was recognized using a single measure of progress that depicted our performance in transferring control 
of the services. Revenue allocated to improvements made during the Improvements Term are being recognized during the 
Improvement Term.  

We recognized $1.6 million, $6.2 million and $11.3 million in research and development revenue in the year ended 

December 31, 2021, 2020 and 2019, respectively.  

License Agreement 

In December 2019, we entered a license agreement with Roche Sequencing Solutions, Inc. (“Roche”) to provide Roche 

with our EvoT4 DNA™ ligase high-performance molecular diagnostic enzyme. The royalty bearing license grants Roche 
worldwide rights to include the EvoT4 DNA™ ligase in its nucleic acid sequencing products and workflows. Under the license 
agreement, we received an initial collaboration fee payment of $0.8 million within 45 days of the effective date of the 
agreement, and we received an additional $0.9 million milestone payment after the completion of technology transfer in 
October 2020. The agreement also contemplates milestone payments to Codexis upon the achievement of various development 
and commercialization events and royalty payments from commercial sales of the enzyme. We recognized research and 
development fees of $0.9 million and $0.9 million for the years ended December 31, 2021 and 2020, respectively. 

Strategic Collaboration and License Agreement 

In March 2020, we entered into a Strategic Collaboration and License Agreement (the “Takeda Agreement”) with Shire 
Human Genetic Therapies, Inc., a wholly-owned subsidiary of Takeda Pharmaceutical Co. Ltd. (“Takeda”) under which we are 
collaborating to research and develop protein sequences for use in gene therapy products for certain diseases (each, a “Field”) 
in accordance with each applicable program plan (each, a “Program Plan”). 

On execution of the Takeda Agreement in March 2020, we received an upfront nonrefundable cash payment of $8.5 million 

and we initiated activities under three Program Plans for Fabry Disease, Pompe Disease, and an undisclosed blood factor 
deficiency respectively (the “Initial Programs”). In May 2021, Takeda elected to exercise its option to initiate an additional 
program for a certain undisclosed rare genetic disorder; as a result, we received the option exercise fee during the third quarter 
of 2021. Pursuant to the Takeda Agreement, we are eligible to receive other payments that include (i) reimbursement of 
research and development fees and preclinical development milestones for the three initial programs of $10.5 million, in 
aggregate, and $8.3 million for the fourth program, (ii) clinical development and commercialization-based milestones, per 
target gene, of up to $100.0 million and (iii) tiered royalty payments based on net sales of applicable products at percentages 
ranging from the mid-single digits to low single-digits. 

103 

 
Revenue recognized relating to the functional licenses provided to Takeda was recognized at a point in time when the 
control of the license transferred to the customer. We recognized research and development revenue related to the Takeda 
Agreement of $7.4 million and $13.2 million in the years ended December 31, 2021 and 2020, respectively. As of 
December 31, 2021 and 2020, we had deferred revenue balances of $2.2 million and $1.5 million, respectively. 

Master Collaboration and Research Agreement and Stock Purchase Agreement 

In June 2020, we entered into a Stock Purchase Agreement with MAI in which we purchased 1,587,050 shares of MAI's 
Series A preferred stock for $1.0 million. In connection with the June 2020, transaction, John Nicols, our President and Chief 
Executive Officer, joined MAI’s board of directors. For additional information, see Note 14, "Related Party Transactions". 

Concurrent with our initial equity investment, we entered into a Master Collaboration and Research Agreement with MAI 

(the “MAI Agreement”) in June 2020, pursuant to which we are performing services utilizing our CodeEvolver® protein 
engineering platform technology to improve DNA polymerase enzymes in exchange for compensation in the form of additional 
shares of MAI's preferred stock. Based on these services, the Company is eligible to earn additional shares of MAI's preferred 
stock. MAI will combine its advanced chemistries with our enzymes to drive the process to commercialization. We are eligible 
to earn such non-monetary payments over 14 months, and any such shares would be issued thirty days in arrears after each 
calendar quarter-end. We are also eligible to receive amounts for bonuses, targets and milestones on achievement of timeline 
and project goals specified in the statement of work ("SOW"). Payments for bonuses, targets and milestones on achievement of 
timeline and project goals are to be issued thirty days after the Company provides notification of completion. Under the MAI 
Agreement, we will have the right to use and sell the engineered enzymes to third parties for any purpose other than for the 
synthesis of native DNA. Under the MAI Agreement, we would make a $0.5 million payment to MAI upon our achievement of 
a milestone of $5.0 million in aggregate commercial sales to third parties of the engineered enzymes or any product 
incorporating or derived from the engineered enzymes for any purpose other than the synthesis of native DNA. The MAI 
Agreement contemplates that we and MAI will enter into a Commercialization and Enzyme Supply Agreement (the “CESA”) 
within six months following the completion of certain timelines specified in the SOW. In addition, we and MAI have agreed to 
certain terms to be contained within the CESA in the event that the CESA becomes executed in the future. Those include: (a) 
that MAI would receive an exclusive license to use the DNA polymerase enzymes engineering by us under the MAI Agreement 
in the synthesis of native DNA and a non-exclusive license to use these enzymes for research and development on the synthesis 
of non-native DNA, and (b) we would become the exclusive manufacturer of these enzymes for MAI, its affiliates and 
licensees. 

We received 3,491,505 and 714,171 shares of MAI's Series A and B preferred stock and recognized $2.0 million and $0.9 

million from these services in the years ended December 31, 2021 and 2020, respectively. Payment for the services rendered 
was received in the form of additional MAI Series A and Series B preferred stock. 

Pfizer purchase orders 

In the first and second quarters of 2021, we began to receive purchase orders from Pfizer, Inc. (“Pfizer”) for large 
quantities of our proprietary enzyme product, CDX-616, for use by Pfizer in the manufacture of a critical intermediate for its 
proprietary active pharmaceutical ingredient, nirmatrelvir. Pfizer markets, sells and distributes nirmatrelvir, in combination with 
the active pharmaceutical ingredient ritonavir, as its PAXLOVID™ (nirmatrelvir tablets; ritonavir tablets) product, which 
received emergency use authorization by the U.S. Food and Drug Administration (“FDA”) in late 2021 for the treatment of 
COVID-19 infections in humans.   

We recognized product revenue of $34.5 million from the sale of quantities of CDX-616 enzyme products to Pfizer in 
2021. Revenues recognized by us from the sale to Pfizer comprised 33% of our total revenues for the year ended December 31, 
2021. As of December 31, 2021, we recorded revenue and contract assets of $1.7 million from the sale of this enzyme product 
that were recognized over time based on the progress of the manufacturing process.   

Note 6. Investments in Non-Marketable Securities 

Non-Marketable Debt Securities 

We classify non-marketable debt securities, which are accounted for as available-for-sale, within Level 3 in the fair value 
hierarchy because we estimate the fair value based on a qualitative analysis using the most recent observable transaction price 
and other significant unobservable inputs including volatility, rights, and obligations of the securities we hold. 

We determine gains or losses on the sale or extinguishment of non-marketable debt securities using a specific identification 
method. Unrealized gains and losses from bifurcated embedded derivatives, which represent share-settled redemption features, 
are recorded as other expense, net, in the consolidated statements of operations. Unrealized gains and losses on non-marketable 

104 

 
 
 
debt securities are recorded as a component of other comprehensive loss until realized. Realized gains or losses are recorded as 
a component of other income (expense), net.  

In November 2020, we purchased convertible subordinated notes issued by Arzeda Corp., an early-stage computational 

protein design company, for $1.0 million. The investment was classified as available-for-sale non-marketable interest-bearing 
debt securities with a carrying value of $1.0 million as of December 31, 2020. In July 2021, we converted the non-marketable 
debt security with a carrying value of $1.3 million into 207,070 shares of Series B-2 preferred stock of Arzeda Corp. During the 
year ended December 31, 2021, we recognized $0.3 million in interest income from interest earned on our investment in this 
debt security. 

There were no investments in non-marketable debt securities at December 31, 2021. As of December 31, 2020, the 

adjusted cost, carrying value and fair value of the non-marketable debt security is the following (in thousands):

Our non-marketable equity securities are investments in privately held companies without readily determinable market 

value and primarily relate to our investments in MAI and Arzeda Corp. These investments are accounted for under the 
measurement alternative and are measured at cost minus impairment, if any, plus or minus changes resulting from observable 
price changes for identical or similar security of the same issuer. Non-marketable equity securities are measured at fair value on 
a non-recurring basis and classified within Level 2 in the fair value hierarchy because we estimate the fair value of these using 
the observable transaction price paid by third party investors for the same or similar security of the same issuers. We adjust the 
carrying value of non-marketable equity securities which have been remeasured during the period and recognize resulting gains 
or losses as a component of other income (expense), net in the consolidated statements of operations.  

For the year ended December 31, 2021, we recognized a $1.0 million unrealized gain in other income (expense), net, in the 

consolidated statements of operations, and included as adjustment to the carrying value of our investment in MAI based on an 
analysis of observed transaction price from MAI's recent round of financing during the third and fourth quarter of 2021. There 
was no remeasurement event for our investment in MAI and Arzeda Corp that occurred during the remainder of 2021. We 
recognized no realized gains or losses during the years ended December 31, 2021 and 2020. The carrying value of our 
investment in MAI was $12.7 million and $1.5 million at December 31, 2021 and December 31, 2020, respectively. The 
carrying value of our investment in Arzeda Corp. was $1.3 million at December 31, 2021.

In 2019, our board of directors (the "Board") and stockholders approved the 2019 Incentive Award Plan (the "2019 Plan"). 
The 2019 Plan superseded and replaced in its entirety our 2010 Equity Incentive Plan (the “2010 Plan”) which was effective in 
March 2010, and no further awards will be granted under the 2010 Plan; however, the terms and conditions of the 2010 Plan 
will continue to govern any outstanding awards thereunder.  

The 2019 Plan provides for the grant of stock options, including incentive stock options and non-qualified stock options, 
stock appreciation rights, restricted stock awards ("RSAs"), restricted stock units ("RSUs"), performance-contingent restricted 
stock units ("PSUs"), performance-based options ("PBOs"), other stock or cash-based awards and dividend equivalents to 
eligible employees and consultants of the Company or any parent or subsidiary, as well as members of the Board.

The number of shares of our common stock available for issuance under the 2019 Plan is equal to the sum of (i) 7,897,144 

shares and (ii) any shares subject to awards granted under the 2010 Plan that were outstanding as of April 22, 2019 and 
thereafter terminate, expire, lapse or are forfeited; provided that no more than 14,000,000 shares may be issued upon the 
exercise of incentive stock options (“ISOs”). In June 2019, 8.1 million shares authorized for issuance under the 2019 Plan were 
registered under the Securities Act of 1933, as amended (the “Securities Act”). 

The 2010 Plan provided for the grant of incentive stock options, non-statutory stock options, RSUs, RSAs, PSUs, PBOs, 

stock appreciation rights, and stock purchase rights to our employees, non-employee directors and consultants. 

As of December 31, 2021, total shares remaining available for issuance under the 2019 Plan were 5.9 million shares. 

Stock Options 

The option exercise price for incentive stock options must be at least 100% of the fair value of our common stock on the 
date of grant and the option exercise price for non-statutory stock options is at least 85% of the fair value of our common stock 
on the date of grant, as determined by the Board. If, at the time of a grant, the optionee directly or by attribution owns stock 
possessing more than 10% of the total combined voting power of all of our outstanding capital stock, the exercise price for 
these options must be at least 110% of the fair value of the underlying common stock. Stock options granted to employees 
generally have a maximum term of ten years and vest over four years from the date of grant, of which 25% vest at the end of 
one year, and 75% vest monthly over the remaining three years. We may grant options with different vesting terms from time to 
time. Unless an employee's termination of service is due to disability or death, upon termination of service, any unexercised 
vested options will be forfeited at the end of three months or the expiration of the option, whichever is earlier. 

Restricted Stock Units ("RSUs") 

We also grant employees RSUs, which generally vest over either a three year period with 33% of the shares subject to the 
RSUs vesting on each yearly anniversary of the vesting commencement date or over a four-year period with 25% of the shares 
subject to the RSU vesting on each yearly anniversary of the vesting commencement date, in each case contingent upon such 
employee’s continued service on such vesting date. RSUs are generally subject to forfeiture if employment terminates prior to 
the release of vesting restrictions. We may grant RSUs with different vesting terms from time to time. 

Performance-contingent Restricted Stock Units ("PSUs") and Performance Based Options ("PBOs") 

The compensation committee of the Board approved, solely in respect of non-executive employees, delegated to our Chief 
Executive Officer the authority to approve grants of PSUs. The compensation committee of the Board also approved grants of 
PBOs and PSUs to our executives. The PSUs and PBOs vest based upon both the successful achievement of certain corporate 
operating milestones in specified timelines and continued employment through the applicable vesting date. When the 
performance goals are deemed to be probable of achievement for these types of awards, recognition of stock-based 
compensation expense commences. Once the number of shares eligible to vest is determined, those shares vest in two equal 
installments with 50% vesting upon achievement and the remaining 50% vesting on the first anniversary of achievement, in 
each case, subject to the recipient’s continued service through the applicable vesting date. If the performance goals are achieved 
at the threshold level, the number of shares eligible to vest in respect of the PSUs and PBOs would be equal to half the number 
of PSUs granted and one-quarter the number of shares underlying the PBOs granted. If the performance goals are achieved at 
the target level, the number of shares eligible to vest in respect of the PSUs and PBOs would be equal to the number of PSUs 
granted and half of the shares underlying the PBOs granted. If the performance goals are achieved at the superior level, the 
number of shares eligible to vest in respect of the PSUs would be equal to two times the number of PSUs granted and equal to 
the number of PBOs granted. The number of shares issuable upon achievement of the performance goals at the levels between 
the threshold and target levels for the PSUs and PBOs or between the target level and superior levels for the PSUs would be 
determined using linear interpolation. Achievement below the threshold level would result in no shares being eligible to vest in 
respect of the PSUs and PBOs.  

In 2021, we awarded PSUs ("2021 PSUs") and PBOs ("2021 PBOs"), each of which commenced vesting based upon the 

achievement of various weighted performance goals, including corporate revenue, performance enzyme segment gross margin, 
major new biotherapeutics publicity events, strategic performance enzyme and biotherapeutics deliverables, safety, and 
technology and strategic plan development. As of December 31, 2021, we estimated that the 2021 PSUs and 2021 PBOs 
performance goals would be achieved at 146% and 73% of the target level, respectively, and recognized stock-based 
compensation expenses accordingly. 

In 2020, we awarded PSUs ("2020 PSUs") and PBOs ("2020 PBOs"), each of which commenced vesting based upon the 

achievement of various weighted performance goals, including corporate revenue, performance enzyme segment gross margin, 
major new biotherapeutics publicity events, strategic performance enzyme and biotherapeutics deliverables, and strategic plan

development. In the first quarter of 2021, we determined that the 2020 PSUs and 2020 PBOs performance goals had been 
achieved at 88% and 44% of the target level, respectively, and recognized the stock-based compensation expenses accordingly. 
Accordingly, 50% of the shares underlying the 2020 PSUs and PBOs vested in the first quarter of 2021 and 50% of the shares 
underlying the 2020 PSUs and PBOs will vest in the first quarter of 2022, in each case, subject to the recipient’s continued 
service on each vesting date. 

In 2019, we awarded PSUs ("2019 PSUs") and PBOs ("2019 PBOs"), each of which commenced vesting based upon the 
achievement of various weighted performance goals, including sustained revenue and performance enzyme growth, strategic 
advancement of biotherapeutics, cash balance and strategic plan development. In the first quarter of 2020, we determined that 
the 2019 PSUs and 2019 PBOs performance goals had been achieved at 84% and 42% of the target level, respectively, and 
recognized the stock-based compensation expenses accordingly. Accordingly, 50% of the shares underlying the 2019 PSUs and 
PBOs vested in the first quarter of 2020 and 50% of the shares underlying the 2019 PSUs and PBOs vested in the first quarter 
of 2021, in each case subject to the recipient’s continued service on each vesting date.

Note 10. Capital Stock 

Equity Distribution Agreement 

We filed a Registration Statement on Form S-3 with the SEC, under which we may sell common stock, preferred stock, 
debt securities, warrants, purchase contracts, and units from time to time in one or more offerings. The registration statement 
became effective on May 7, 2021. In May 2021, we entered into an Equity Distribution Agreement ("EDA") with Piper Sandler 
& Co ("PSC"), under which PSC, as our exclusive agent, at our discretion and at such times that we may determine from time 
to time, may sell over a three-year period from the execution of the EDA up to a maximum of $50.0 million of shares of our 
common stock. Under the terms of the EDA, PSC may sell the shares at market prices by any method that is deemed to be an“at 
the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended.  

We are not required to sell any shares at any time during the term of the EDA. The EDA will terminate upon the earlier of: 
(i) the issuance and sale of all shares through PSC on the terms and conditions of the EDA, or (ii) the termination of the EDA in 
accordance with its terms. Either party may terminate the EDA at any time upon written notification to the other party in 
accordance with the EDA, and upon such notification, the offering will terminate. Under no circumstances shall any shares be 
sold pursuant to the EDA after the date which is three years after the registration statement is first declared effective by the 
SEC. We agreed to pay PSC a commission of 3% of the gross sales price of any shares sold pursuant to the EDA. With the 
exception of certain expenses, we will pay PSC up to 8% of the gross sales price of the shares sold pursuant to the EDA for a 
combined amount of commission and reimbursement of PSC's expenses and fees.  

During the year ended December 31, 2021, no shares of our common stock were issued pursuant to the EDA. As of 

December 31, 2021, $50.0 million of shares remained available for sale under the EDA.

Public Offerings 

In December 2020, we completed an underwritten public offering in which we issued and sold 4.9 million shares of our 
common stock, par value $0.0001 per share, at a public offering price of $17.50 per share. We received gross proceeds of $86.3 
million, net of underwriting discounts and commissions of $5.2 million and direct offering expenses of $0.3 million for net 
proceeds of $80.8 million. 

Private Placement 

In June 2019, we entered into a Securities Purchase Agreement with an affiliate of Casdin Capital, LLC ("Casdin") 

pursuant to which we issued and sold to Casdin 3,048,780 shares of our common stock at a purchase price of $16.40 per share. 
After deducting issuance costs of $0.1 million from the Private Offering, our net proceeds were $49.9 million. The Private 
Offering was exempt from registration pursuant to the exemption for transactions by an issuer not involving any public offering 
under Section 4(a)(2) the Securities Act, and Regulation D under the Securities Act. 

Note 11. 401(k) Plan 

In January 2005, we implemented a 401(k) Plan covering certain employees. Currently, all of our United States based 
employees over the age of 18 are eligible to participate in the 401(k) Plan. Under the 401(k) Plan, eligible employees may elect 
to reduce their current compensation up to a certain annual limit and contribute these amounts to the 401(k) Plan. We may make 
matching or other contributions to the 401(k) Plan on behalf of eligible employees. We recorded employer matching 
contributions expense of $1.1 million, $0.8 million, and $0.7 million in the years ended December 31, 2021, 2020, and 2019, 
respectively.

ASC 740 requires that the tax benefit of NOLs, temporary differences and credit carryforwards be recorded as an asset to 

the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is 
dependent on our ability to generate sufficient taxable income within the carryforward period. Because of our history of 
operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax

benefits is currently not more likely than not to be realized and, accordingly, has provided a valuation allowance against our 
deferred tax assets. Accordingly, the net deferred tax assets in all our jurisdictions have been fully reserved by a valuation 
allowance. The net valuation allowance increased by $9.6 million during the year ended December 31, 2021, increased by 
$6.4 million during the year ended December 31, 2020, and increased by $6.5 million during the year ended December 31, 
2019. At such time as it is determined that it is more likely than not that the deferred tax assets are realizable, the valuation 
allowance will be reduced.

Current U.S. federal and California tax laws include substantial restrictions on the utilization of NOLs and tax credit 

carryforwards in the event of an ownership change of a corporation. Accordingly, the Company's ability to utilize NOLs and tax 
credit carryforwards may be limited as a result of such ownership changes. We performed an analysis in 2020 and determined 
that there was not a limitation that would result in the expiration of carryforwards before they are utilized. 

Income tax expense or benefit from continuing operations is generally determined without regard to other categories of 
earnings, such as discontinued operations and other comprehensive income. An exception is provided in ASC 740 when there is 
aggregate income from categories other than continuing operations and a loss from continuing operations in the current year. In 
this case, the tax benefit allocated to continuing operations is the amount by which the loss from continuing operations reduces 
the tax expenses recorded with respect to the other categories of earnings, even when a valuation allowance has been 
established against the deferred tax assets. In instances where a valuation allowance is established against current year losses, 
income from other sources is considered when determining whether sufficient future taxable income exists to realize the 
deferred tax assets. 

In 2014, we determined that the undistributed earnings of our India subsidiary will be repatriated to the United States, and 

accordingly, we have provided a deferred tax liability totaling $23 thousand and $32 thousand as of December 31, 2021 and 
2020 respectively, for local taxes that would be incurred upon repatriation.  

We apply the provisions of ASC 740 to account for uncertain income taxes. A reconciliation of the beginning and ending

We recognize interest and penalties as a component of our income tax expense. Total interest and penalties recognized in 

the consolidated statements of operations were $61 thousand, $39 thousand and $32 thousand in 2021, 2020 and 2019, 
respectively. Total penalties and interest recognized in the balance sheet was $0.5 million, $0.4 million and $0.4 million as of 
December 31, 2021, 2020 and 2019, respectively. The total unrecognized tax benefits that, if recognized currently, would 
impact our company’s effective tax rate were $0.3 million as of December 31, 2021, 2020 and 2019. We do not expect any

Note 13. Commitments and Contingencies 

Operating Leases 

Our headquarters are located in Redwood City, California, where we occupy approximately 77,300 square feet of office 
and laboratory space in multiple buildings within the same business park of Metropolitan Life Insurance Company ("MetLife"). 
Our lease agreement with MetLife ("RWC Lease") includes approximately 28,200 square feet of space located at 200 and 220 
Penobscot Drive, Redwood City, California (the “200/220 Penobscot Space”) and approximately 37,900 square feet of space 
located at 400 Penobscot Drive, Redwood City, California (the “400 Penobscot Space”) (the 200/220 Penobscot Space and the 
400 Penobscot Space are collectively referred to as the “Penobscot Space”), and approximately 11,200 square feet of space 
located at 501 Chesapeake Drive, Redwood City, California (the “501 Chesapeake Space”). 

Until the end of January 2020, we also leased approximately 29,900 square feet of space located at 101 Saginaw Drive, 
Redwood City, California (the “Saginaw Space”). During January 2020, we subleased approximately 26,500 square feet of the 
Saginaw Space to Minerva Surgical, Inc. The lease and sublease for the Saginaw Space both expired at the end of January 2020. 
During the period from February 1, 2020 through April 30, 2020, we subleased approximately 3,400 square feet at 101 Saginaw 
Drive from Minerva Surgical, Inc. The sublease expired at the end of April 2020. 

We entered into the initial lease with MetLife for our facilities in Redwood City in 2004 and the RWC Lease has been 
amended multiple times since then to adjust the leased space and terms of the Lease. In February 2019, we entered into an 
Eighth Amendment to the Lease (the “Eighth Amendment”) with MetLife with respect to the Penobscot Space and the 501 
Chesapeake Space to extend the term of the Lease for additional periods. Pursuant to the Eighth Amendment, the term of the 
lease of the Penobscot Space has been extended through May 2027. The lease term for the 501 Chesapeake Space has been 
extended to May 2029. We have one (1) option to extend the term of the lease for the Penobscot Space for five (5) years, and 
one (1) separate option to extend the term of the lease for the 501 Chesapeake Space for five (5) years. 

Pursuant to the terms of the RWC Lease, we exercised our right to deliver a letter of credit in lieu of a security deposit. The 
letter of credit is collateralized by deposit balances held by the bank in the amount of $1.1 million as of December 31, 2021 and 
2020, and are recorded as non-current restricted cash on the consolidated balance sheets. 

We entered into a short-term office lease in San Carlos, California during the second quarter of 2021 and this lease will 

expire in April 2022. Our remaining future commitment pursuant to this lease is $40 thousand as of December 31, 2021. 

In January 2021, we entered into a lease agreement with ARE-San Francisco No. 63, LLC (“ARE”) to lease a portion of a 

facility comprising approximately 36,593 rentable square feet in San Carlos, California to serve as additional office and 
research and development laboratory space (the “San Carlos Space”). The budget provided a net tenant improvement allowance 
of $6.3 million and an additional allowance of up to $2.7 million. ARE will have an enforceable right to payment by us in the 
form of equal monthly additional rent payments at a certain interest rate through the lease term for the additional allowance. 
The terms include an initial annualized base rent of $2.5 million, subject to scheduled 3% annual rent increases, an annualized 
additional allowance payment of $0.4 million, plus certain operating expenses. The lease has a 10-year term from the lease 
commencement date with one option to extend the term for an additional period of 5 years. We have provided ARE with a $0.5 
million security deposit in the form of a letter of credit. We have the right to sublease the facility, subject to landlord consent. 
We commenced occupancy of the San Carlos Space in December 2021 and recognized the right of use asset and the 
corresponding operating lease liability. 

We are required to restore certain areas of the Redwood City and San Carlos facilities that we are renting to their original 

form. We are expensing the asset retirement obligation over the terms of the respective leases. We review the estimated 
obligation each reporting period and make adjustments if our estimates change. We recorded asset retirement obligations of 
$0.4 million and $0.2 million as of December 31, 2021 and 2020, respectively, which are included in other liabilities on the 
consolidated balance sheets. Accretion expense related to our asset retirement obligations was nominal in 2021 and 2020.

We enter into supply and service arrangements in the normal course of business. Supply arrangements are primarily for 
fixed-price manufacture and supply. Service agreements are primarily for the development of manufacturing processes and 
certain studies. Commitments under service agreements are subject to cancellation at our discretion which may require payment 
of certain cancellation fees. The timing of completion of service arrangements is subject to variability in estimates of the time 
required to complete the work.

In June 30, 2017, we entered into a credit facility (the "Credit Facility") with Western Alliance Bank consisting of term 

loans (“Term Debt”) up to $10.0 million, and advances ("Advances") under a revolving line of credit ("Revolving Line of 
Credit") up to $5.0 million with an accounts receivable borrowing base of 80% of eligible accounts receivable. In September 
2021, we entered into the Ninth Amendment to the Credit Facility whereby we may draw on the Term Debt and the Revolving 
Line of Credit at any time prior to December 31, 2021 and October 1, 2024, respectively. The right to take draws on the Term 
Debt expired on December 31, 2021 and no amounts were drawn under the Credit Facility as of December 31, 2021. On 
October 1, 2024, loans drawn under the Revolving Line of Credit terminate. Advances made under the Revolving Line of 
Credit bear interest at a variable annual rate equal to the equal to the greater of (i) 4.25% or (ii) the sum of (A) the prime rate 
plus (B) 1.00%.  

Our obligations under the Credit Facility are secured by a lien on substantially all of our personal property other than our 

intellectual property. The Credit Facility includes a number of customary covenants and restrictive financial covenants 
including meeting minimum product revenue levels and maintaining certain minimum cash levels with the lender. The Credit 
Facility's financial covenants restrict the ability of the Company to transfer collateral, incur additional indebtedness, engage in 
mergers or acquisitions, pay dividends or make other distributions, make investments, create liens, sell assets, or sell certain 
assets held at foreign subsidiaries. A failure to comply with these covenants could permit the lender to exercise remedies against 
us and the collateral securing the Credit Facility, including foreclosure of our properties securing the Credit Facility and our 
cash. At December 31, 2021, we were in compliance with the covenants for the Credit Facility.  

Legal Proceedings 

We are not currently a party to any material pending litigation or other material legal proceedings. 

Indemnifications 

We are required to recognize a liability for the fair value of any obligations we assume upon the issuance of a guarantee. 

We have certain agreements with licensors, licensees and collaborators that contain indemnification provisions. In such 
provisions, we typically agree to indemnify the licensor, licensee and collaborator against certain types of third party claims. 
The maximum amount of the indemnifications is not limited. We accrue for known indemnification issues when a loss is 
probable and can be reasonably estimated. There were no accruals for expenses related to indemnification issues for any periods 
presented. 

Note 14. Related Party Transactions  

Molecular Assemblies, Inc. 

In June 2020, we entered into a Stock Purchase Agreement with MAI pursuant to which we purchased 1,587,050 shares of 

MAI's Series A preferred stock for $1.0 million. In connection with the transaction, John Nicols, our President and Chief 
Executive Officer, also joined MAI’s board of directors. Concurrently with our initial equity investment, we entered into the 
MAI Agreement with MAI, pursuant to which we are performing services utilizing our CodeEvolver® protein engineering 
platform technology to improve DNA polymerase enzymes in exchange for compensation in the form of additional shares of 
MAI's Series A preferred stock. In April 2021, we purchased an additional 1,000,000 shares of MAI's Series A preferred stock 
for $0.6 million. In September 2021, we purchased 9,198,423 shares of MAI's Series B preferred stock for $7.0 million. In the 
fourth quarter of 2021, we became eligible to receive the primary milestone payment of $1.0 million which we received in the 
form of additional of 1,587,049 Series B preferred stock during December 2021. 

119 

 
 
 
 
 
 
 
 
 
 
  
 
We recognized $2.0 million and $0.9 million in research and development revenue from transactions with MAI in the years 
ended December 31, 2021 and 2020, respectively. We received 3,491,505 and 714,171 shares of MAI's Series A and B preferred 
stock from research and development services we provided to MAI for the years ended December 31, 2021 and 2020, 
respectively. As of December 31, 2021, we have 16,705,320 shares of MAI's Series A and B preferred stock that we have 
earned or purchased since executing the Stock Purchase Agreement with MAI.  

The carrying value of our investment in MAI Series A and B preferred stock was $12.7 million and $1.5 million at 

December 31, 2021 and 2020, respectively. We had $0.2 million and nil in deferred revenue as of December 31, 2021 and 2020, 
respectively, and nil and $0.5 million in contract assets due from MAI for services rendered as of December 31, 2021 and 2020, 
respectively. Payment for the services rendered was received in the form of additional Series A and Series B preferred stock. 
For additional information, see Note 5, "Collaborative Arrangements". 

AstraZeneca PLC 

Pam P. Cheng, who served as a member of our board of directors until June 2020, joined AstraZeneca PLC as Executive 
Vice President, Operations and Information Technology in June 2015. We sold biocatalyst products to AstraZeneca PLC and its 
controlled purchasing agents and contract manufacturers. We recognized $0.1 million of revenue in 2020, through the date of 
Ms. Cheng's departure from our board of directors. As of December 31, 2020, we had no receivables from AstraZeneca PLC 
and its controlled purchasing agents and contract manufacturers that was generated during the related party period. 

Note 15. Segment, Geographical and Other Revenue Information 

Segment Information 

We manage our business as two business segments: Performance Enzymes and Novel Biotherapeutics. Our chief operating 

decision maker ("CODM") is our Chief Executive Officer. Our business segments are primarily based on our organizational 
structure and our operating results as used by our CODM in assessing performance and allocating resources for the Company. 

We report corporate-related expenses such as legal, accounting, information technology, and other costs that are not 

otherwise included in our reportable business segments as "Corporate costs." All items not included in income (loss) from 
operations are excluded from the business segments. 

We manage our assets on a total company basis, not by business segment, as the majority of our operating assets are shared 

or commingled. Our CODM does not review asset information by business segment in assessing performance or allocating 
resources, and accordingly, we do not report asset information by business segment. 

Factors considered in determining the two reportable segments of the Company include the nature of business activities, 
the management structure directly accountable to our CODM for operating and administrative activities, availability of discrete 
financial information and information presented to the Board of Directors. Our CODM regularly reviews our segments and the 
approach provided by management for performance evaluation and resource allocation.  

Operating expenses that directly support the segment activity are allocated based on segment headcount, revenue 

contribution or activity of the business units within the segments, based on the corporate activity type provided to the segment. 
The expense allocation excludes certain corporate costs that are separately managed from the segments. This provides the 
CODM with more meaningful segment profitability reporting to support operating decisions and allocate resources.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL 
DISCLOSURES 

None. 

Evaluation of Disclosure Controls and Procedures 

ITEM 9A. CONTROLS AND PROCEDURES 

Our management, under the supervision of our Chief Executive Officer and Chief Financial Officer and with the participation 
of our disclosure committee, evaluated the effectiveness of the design and operation of our disclosure controls and procedures 
as of December 31, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the 
Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be 
disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported 
within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, 
controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit 
under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and 
Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our 
Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of 
December 31, 2021 at the reasonable assurance level. 

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 
is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed to 
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for 
external reporting purposes in accordance with United States generally accepted accounting principles. 

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial 
Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 
2021 based on the guidelines established in Internal Control-Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission ("COSO"). Based on the results of our evaluation, our management 
concluded that our internal control over financial reporting was effective as of December 31, 2021. We reviewed the results of 
management’s assessment with our Audit Committee. 

Our internal control over financial reporting as of December 31, 2021 has been audited by BDO USA, LLP, an independent 
registered public accounting firm, as stated in their report which is included in Item 8 of this Annual Report. 

Inherent Limitations on Effectiveness of Controls 

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, 
even if determined effective and no matter how well designed and operated, can provide only reasonable assurance of achieving 
the desired control objectives to prevent or detect misstatements. In addition, the design of disclosure controls and procedures 
must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the 
benefits of possible controls and procedures relative to their costs. Also, projections of any evaluation of effectiveness to future 
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate. 

Changes in Internal Control over Financial Reporting  

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) 
identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 of the Exchange Act, which 
occurred during the fourth fiscal quarter of the year ended December 31, 2021, which has materially affected, or is reasonably 
likely to materially affect, our internal control over financial reporting.
