This presentation has been prepared by resTORbio, Inc. (“we,” ”us,” “our,” “resTORbio,” or the “Company”) and is made for informational purposes only and does not constitute an offer to sell or a solicitation of an offer to buy securities. This presentation may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements regarding the safety, efficacy and regulatory and clinical progress of our product candidates, including RTB101 alone and in combination with a rapalog, such as everolimus or sirolimus. All such forward-looking statements are based on management’s current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. The use of words such as, but not limited to, “may,” “might,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “intend,” “future,” “potential,” or “continue,” and other similar words or expressions are intended to identify forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, our clinical results and other future conditions. All statements other than statements of historical facts contained in this presentation, including statements regarding: future results of operations and financial position; business strategy; current and prospective product candidates; ongoing and planned clinical trials and preclinical activities, including the initiation, timing, enrollment, progress and results of our preclinical and clinical studies and our research and development programs; product approvals; research and development costs; current and prospective collaborations; the timing and likelihood of success of our Phase 1b/2a clinical trial of RTB101 alone and in combination with sirolimus in Parkinson’s Disease; the timing or likelihood of regulatory filings and approvals; expectations regarding market acceptance and size; plans for launch and commercialization; plans and objectives of management for future operations; and future results of anticipated product candidates, are forward-looking statements. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. No representations or warranties (expressed or implied) are made about the accuracy of any such forward-looking statements. These statements are also subject to a number of material risks and uncertainties that are discussed in the section entitled "Risk Factors" in resTORbio’s annual report on Form 10-K for the fiscal year ended December 31, 2018, as well as discussions of potential risks, uncertainties, and other important factors in resTORbio's subsequent filings with the Securities and Exchange Commission. Any forward-looking statement speaks only as of the date on which it was made. Neither we, nor our affiliates, advisors or representatives, undertake any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Certain information contained in this presentation relates to or is based on studies, publications, surveys and other data obtained from third-party sources and the Company’s own internal estimates and research. While we believe these third-party sources to be reliable as of the date of this presentation, we have not independently verified, and we make no representation as to the adequacy, fairness, accuracy or completeness of any information obtained from third-party sources. In addition, all of the market data included in this presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. Finally, while we believe our own internal research is reliable, such research has not been verified by any independent source. Forward-looking statements

Parkinson’s Disease Prevalence: Parkinson’s disease (PD) is the second most common neurodegenerative disease and affects 1% of population over 55 years of age Pathobiology: PD is characterized by loss of >50% of the neurons that produce the neurotransmitter dopamine in a specific area of the brain (substantia nigra) Clinical manifestations: Four cardinal motor symptoms: Resting tremor Bradykinesia (slowed movements) Muscle rigidity Postural instability All current therapies treat symptoms of PD but do not alter disease progression Image from Wikiwand
TORC1 inhibitors may be of therapeutic benefit in Parkinson’s disease Induction of autophagy with a TORC1 inhibitor leads to the clearance of a-synuclein aggregates in a preclinical PD model Malagelada et al. J Neurosci, 2010; Crews et al. PLoS one, 2010 # dead neurons Vehicle TOR inhibitor Vehicle TOR inhibitor Control MPTP Treatment Mouse TORC1 inhibition prevents neuronal loss and improves motor function in multiple PD preclinical models
TORC1 Inhibitors that will be evaluated in a Phase 1b/2a trial in Parkinson’s Disease SIrolimus: Allosteric inhibitor of TORC1 Consistently inhibits phosphorylation of only some targets downstream of TORC1 Approved for use in humans sirolimus (rapamycin) RTB101: ATP competitive catalytic site inhibitor of mTOR protein kinase Inhibits phosphorylation of all targets downstream of TORC1 May have advantages over rapalogs for PD Crosses the blood brain barrier in preclinical models RTB101

Summary Protein aggregation is a common pathogenic mechanism underlying multiple neurodegenerative diseases Induction of autophagy may have therapeutic benefit in neurodegenerative diseases by clearing toxic protein aggregates In preclinical models, TORC1 inhibition with RTB101 alone or in combination with a rapalog induces autophagy Phase 1b/2a study or RTB101 alone and in combination with sirolimus is underway
