Forward Looking Statements This presentation contains “forward-looking statements” that involve
substantial risks and uncertainties for purposes of the safe harbor provided by the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this presentation regarding strategy,
future operations, future financial position, future revenue, projected expenses, prospects, plans and objectives of management are forward-looking statements. In addition, when or if used in this presentation, the words “may,” “could,”
“should,” “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “predict” and similar expressions and their variants may identify forward-looking statements. Examples of forward-looking statements include, but are not limited to, the
approach we are taking to discover and develop novel therapeutics using synthetic biology; statements regarding the potential of our platform to develop therapeutics to address a wide range of diseases, including: inborn errors of metabolism,
liver disease, inflammatory and immune disorders, and cancer; the future clinical development of Synthetic Biotic medicines; the potential of our technology to treat hyperammonemia and phenylketonuria; the expected timing of our anticipated
clinical trial initiations; the benefit of orphan drug and fast track status; the adequacy of our capital to support our future operations and our ability to successfully initiate and complete clinical trials; the results of our collaborations;
and the difficulty in predicting the time and cost of development of our product candidates. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without
limitation: the uncertainties inherent in the preclinical development process; our ability to protect our intellectual property rights; and legislative, regulatory, political and economic developments, as well as those risks identified under
the heading “Risk Factors” in our filings with the SEC. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements
that are included herein and elsewhere, including the risk factors included in our Annual Report on Form 10-Q filed with the SEC on August 8, 2019. The forward-looking statements contained in this presentation reflect our current views with
respect to future events. We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements in the future, we specifically disclaim any obligation to do
so. These forward-looking statements should not be relied upon as representing our view as of any date subsequent to the date hereof.

UREA CYCLE DISORDERS (UCD) SYNB1020 for Hyperammonemia Indications Characterized by Systemic Ammonia
Accumulation Neuropsychiatric complication in patients with end-stage liver disease (cirrhosis)Liver dysfunction leads to ammonia accumulationToxic to brain, leading to HE crisis & hospitalizationPatients: 165,000 diagnosed overt patients
in USUp to 70% of patients with cirrhosis characterized as covert (subclinical)Treatment: Lactulose: laxative with significant side effectsRifaximin: reduction in overt HE recurrence Genetic defects in Urea CycleDeficiency in one of the six
enzymes Nitrogen accumulates as toxic ammonia leading to metabolic crisisPatients: ~2,000 diagnosed in US; similar in EUTreatment: Ammonia scavengers: Buphenyl® (sodium phenylbutyrate), Ravicti® (glycerol phenylbuterate)Low protein diet with
amino acid supplements Target Profile to Address Unmet Need:Reduce episodes of hospitalizationImprove cognitive outcomes, Quality of Life HEPATIC ENCEPHALOPATHY (HE) Target Profile to Address Unmet Need:Maintain blood ammonia in normal
range, avoid crisisProtein liberalization: 50-100% more per dayOral administration
Arginine Urea SYNB1020 Mechanism of Action: Dose-responsive ammonia lowering in multiple preclinical
models Conversion of Toxic Ammonia into Beneficial Arginine for the Treatment of UCD and HE Ammonia/NH4Cl UreaCycle Converts ammonia to Arginine Can re-enter the Urea Cycle Ammonia metabolism blocked in disease

PKU is a rare inherited amino acid metabolism disorder Causes build up of amino acid phenylalanine
(Phe) in the bodyToday, less than half of adults are at or below target Phe levels of 120-360 mmol / LIf left untreated, symptoms include cognitive impairment, convulsions, behavioral problems, skin rashPatients:16,500 diagnosed in US, similar
in EU5Treatment: Phenylalanine is found in all proteins therefore low protein diet is followed (no meat, dairy, nuts, eggs)KUVAN® (sapropterin dihydrochloride): PAH cofactor. 20-40% of patients are respondersPalynziqTM (pegvaliase-pqpz):
injectable, pegylated, bacterial enzyme (phenylalanine ammonia-lyase or PAL) for treatment of adult patients SYNB1618 for Phenylketonuria (PKU) Target Profile to Address Unmet Need:Manage Phe below target levels to prevent irreversible
cognitive damageIncrease natural protein intake: classic PKU patients’ natural protein intake is typically less than 10g Oral dosing without systemic toxicity Goal: Managing Plasma Phe Levels
