Forward-Looking Statements Certain statements contained in this Presentation regarding matters that are not historical facts, are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, known as the PSLRA. These include statements regarding the sufficiency of our current cash and cash equivalents to support planned operations into Q4 2026; our planned clinical programs, including the timing and outcome of planned clinical trials; the timing and potential outcome of discussions with regulators regarding the results of the AMPLIFY-7P trial and plans for an ELI-002 7P Phase 3 trial; the potential for advancement of ELI-002 7P into a Phase 3 trial, including the timing and design of any such trial; the potential for clinical benefit, particularly for R0 resected pancreatic cancer patients; the promise of immunological targeting of mKRAS in patients considered to be refractory to immunotherapy; the potential of our product candidates, including the potential of ELI-002 7P; the potential market opportunity for ELI-002 7P; the potential for ELI-002 7P to address a significant unmet need in the adjuvant PDAC setting; the timing and outcomes of any financing or partnering opportunities; the potential for future expansion of ELI-002 to other indications, including in mKRAS positive lung cancer and other mKRAS positive cancers; the potential benefits and effectiveness of off-the-shelf immunotherapy approaches; and other statements regarding management’s intentions, plans, beliefs, expectations or forecasts for the future and, therefore, you are cautioned not to place undue reliance on them. No forward-looking statement can be guaranteed and actual results may differ materially from those projected. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by law. We use words such as “anticipates,” “believes,” “plans,” “expects,” “projects,” “future,” “intends,” “may,” “will,” “should,” “could,” “estimates,” “predicts,” “potential,” “continue,” “guidance,” and similar expressions to identify these forward-looking statements that are intended to be covered by the safe-harbor provisions of the PSLRA. Such forward-looking statements are based on our expectations and involve risks and uncertainties; consequently, actual results may differ materially from those expressed or implied in the statements due to a number of factors, including, but not limited to, our plans to develop and commercialize our product candidates, including ELI- 002 7P; the timing of initiation of our planned clinical trials; the timing of the availability of data from our clinical trials; the timing of any planned investigational new drug application or new drug application; our plans to research, develop and commercialize our current and future product candidates; and our estimates regarding future revenue, expenses, capital requirements and need for additional financing. New factors emerge from time to time, and it is not possible for us to predict all such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. These risks are more fully discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 12, 2026, as updated by subsequent reports and other documents filed from time to time with the SEC. Forward- looking statements included in this Presentation are based on information available to us as of the date of this Presentation. We do not undertake any obligation to update such forward-looking statements to reflect events or circumstances after the date of this Presentation, except to the extent required by law. 2 | Elicio Therapeutics

Biology of R1 Resected PDAC is Distinct from R0 Resected 14 R1 margins found in ~20% of PDAC resections indicate unique biology of disease underlying increased recurrence risk 1 Hernandez, et al. Annals Surg. 2009; 2Tummers, et al. Br J Surg. 2019; 3 Esposito, et al. Annals Surg Oncol. 2008 17 patients underwent extended surgery to convert R1 → R0 margins during the operation. Median OS was 11 months for R1 → R0, and 13 months in R1 without extra surgery, indicating that tumor biology beyond the presence of cancer cells at the margin is responsible.
