statements contain these identifying words. Forward-looking statements include statements concerning, among other things, plans related to the company’s research and development activities, and the timing and potential results thereof;
expectations regarding the company’s clinical trial designs, enrollment, event accumulation and progress, regulatory pathway, product profile, potential patient populations, indication, and administration paradigm for VYD2311, including with
respect to the company’s REVOLUTION clinical program and the timing of activities, expenditures, and results related thereto; the company’s commercialization plans, strategies, goals, and expectations, including with respect to its
preparations for the potential commercial launch of VYD2311, if approved; expectations regarding the COVID landscape and potential advantages of monoclonal antibodies (mAbs); estimates based on arithmetic extrapolation of systemic reactogenicity
symptom burden at the population level; the potential net symptomatic benefit of immunization from a very low vaccine efficacy mAb; the company’s plans and expectations with respect to the commercialization of PEMGARDA® (pemivibart); the
potential of VYD2311 as a novel mAb candidate that may be able to deliver clinically meaningful titer levels through more patient-friendly means; the company’s plans and expectations with respect to its other product candidates, including
VMS063 and VBY329; expectations about the market size and opportunity for the company’s product candidates, as well as its market position; expectations regarding the company’s ‘Antibodies for Any Body’ campaign and
partnership with Lindsey Vonn; the company’s business strategies and objectives, and ability to execute on them; the company’s potential to change COVID-19 prevention near-term with a potential best-in-class technology, and major follow-on opportunities; the company’s future prospects; and other statements that are not
historical fact. The company may not actually achieve the plans, intentions, or expectations disclosed in the company’s forward-looking statements and you should not place undue reliance on the company’s forward-looking statements. These
forward-looking statements involve risks and uncertainties that could cause the company’s actual results to differ materially from the results described in or implied by the forward-looking statements, including, without limitation:
uncertainties regarding the company’s expectations, projections, and estimates regarding future costs and expenses, future revenue, capital requirements, and the availability of and the need for additional financing; uncertainties regarding
market acceptance, payor coverage, and reimbursement, or future revenue generated by any authorized or approved product; how long the emergency use authorization (EUA) granted by the U.S. Food & Drug Administration (FDA) for PEMGARDA will
remain in effect and whether such EUA is revised or revoked by the FDA; the ability to maintain a continued acceptable safety, tolerability, and efficacy profile of any product candidate following regulatory authorization or approval; the success of
the company’s in-house sales force, and the company’s ability to maintain and expand sales, marketing, and distribution capabilities to successfully commercialize any authorized or approved
product; changes in expected or existing competition; changes in the regulatory environment; the outcome of the company’s engagement with regulators; uncertainties related to the regulatory authorization or approval process, and available
development and regulatory pathways; whether or not any preclinical candidate identified by the company is determined to be suitable for clinical development; the timing, progress, and results of the company’s discovery, preclinical, and
clinical development activities; clinical trial site activation, enrollment, and event accumulation rates; unexpected safety or efficacy data observed during preclinical studies or clinical trials; the risk that results of nonclinical studies or
clinical trials may not be predictive of future results, and interim data are subject to further analysis; the company’s ability to generate the data needed to support a potential Biologics License Application (BLA) submission for VYD2311;
potential variability in neutralizing activity of product candidates tested in different assays, such as pseudovirus assays and authentic assays; variability of results in models and methods used to predict activity against SARS-CoV-2 variants; whether the epitopes that pemivibart and VYD2311 target remain structurally intact and the company’s product candidates are able to demonstrate and
sustain neutralizing activity against major SARS-CoV-2 variants, particularly in the face of viral evolution; the risk that a lack of awareness of mAb therapies and
regulatory scrutiny of mAb therapies to prevent or treat COVID-19 or other infectious diseases may adversely impact the development or commercial success of the company’s product candidates; the
company’s reliance on third parties; whether the anticipated benefits of the company’s partnership with Lindsey Vonn are realized; complexities of manufacturing mAb therapies; macroeconomic and political uncertainties; the
company’s ability to continue as a going concern; and whether the company has adequate funding to meet future operating expenses and capital expenditure requirements. Other factors that may cause the company’s actual results to differ
materially from those expressed or implied in the forward-looking statements in this presentation are described under the heading “Risk Factors” in the company’s Annual Report on Form 10-K
