**PART III — NARRATIVE**

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As previously reported by Eloxx Pharmaceuticals, Inc. (the "Company") in its Form 12b-25 (NT 10-K) filed with the Securities and Exchange Commission on April 1, 2025 and on April 1, 2024, the Company was not able to file its Annual Reports on Form 10-K for the fiscal years ended December 31, 2004 and 2023 because the Company was unable to allocate the financial resources necessary to engage its independent public accounting firm to perform audits of the Company's financial statements for the years ended December 31, 2024 and 2023 to be included in the Form 10-K for each of those years. Such financial constraints are ongoing, and the Company is unable to engage its independent public accounting firm to conduct a review of the unaudited condensed consolidated financial statements (the "Second Quarter Financial Statements") to be included in the Company's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 (the "Form 10-Q"). Therefore, the Company is unable to File the Form 10-Q within the prescribed time period without unreasonable effort at expense.
