As of June 30,\n2026, cash and cash equivalents were approximately $30 million, which are\nexpected to fund operations into late-2027.\n\n“The partnership with Sentynl Therapeutics which we announced earlier today\nmarks a significant milestone for our alvelestat program and for the Company\nas a whole. We are now working together to refine the design of the global\nPhase 3 study for our potential first-in-class oral therapy for AATD-LD and\nlook forward to a continued close collaboration during the short option\nperiod. Assuming exercise of the license option by Sentynl, we plan to\ninitiate the Phase 3 trial in early 2027,” said Denise Scots-Knight, Chief\nExecutive Officer of Mereo BioPharma. “Additionally, alongside our partner\nUltragenyx, we have had initial regulatory interactions on setrusumab with the\nFDA and the MHRA and we expect to be in a position to provide an update on the\npotential path forward by the end of this year. We finished the quarter with\napproximately $30 million in cash. Thanks to our careful expense management,\nwe now expect that this cash will provide runway into late-2027, exclusive of\nthe potential $40 million in upfront and R&D payments that we are eligible to\nreceive on exercise of the alvelestat option by Sentynl.”\n\nSecond Quarter 2026 Highlights, Recent Developments, and Anticipated\nMilestones \n\nSetrusumab (UX143)\n* The Orbit and the Cosmic Phase 3 studies did not achieve statistical\nsignificance against the primary endpoints of reduction in annualized clinical\nfracture rate, however, both achieved high statistical significance against\nthe key secondary endpoint of improvement in bone mineral density, as well as\nreductions in vertebral fractures and improvements in patient reported\noutcomes (PROs) associated with disease severity, pain / discomfort and daily\nactivities, with these PRO improvements achieving statistical significance in\nthe Orbit study. Setrusumab also achieved meaningful reductions in fractures\nin certain bones and in patients with higher fracture frequencies. Both\nstudies demonstrated a safety profile consistent with that observed in\nprevious trials.\n* Mereo and its partner, Ultragenyx Pharmaceutical, Inc. (Ultragenyx), are\nengaged with regulatory agencies to determine a potential path forward for\nsetrusumab in pediatric OI patients and, to-date, have held discussions with\nthe regulators in the U.S. and the U.K. The FDA indicated openness to\nconsidering alternative approaches to fracture analysis, with additional\nconversations needed to further define what additional clinical data would be\nneeded to support a potential BLA. In recent communications with the MHRA,\nthey encouraged further dialogue on any future development proposal, and we\nplan to have further interactions following the FDA discussions.\nAlvelestat (MPH-966)\n* Mereo recently announced an option and license agreement with Sentynl\nTherapeutics, Inc. (Sentynl), a wholly owned subsidiary of Zydus Lifesciences\nLimited. Sentynl has the right to acquire a license for the U.S. commercial\nand global manufacturing rights to alvelestat for AATD-LD. * Sentynl is a\nCalifornia-based, commercial-stage biopharmaceutical company with three\ncurrently approved products for rare diseases.\n* Under the agreement, the companies will collaborate to refine the design of\nthe planned global Phase 3 trial of alvelestat and to advance the\nmanufacturing during the short option period. * Mereo will receive a\nnon-refundable option fee and, on option exercise, would also be eligible to\nreceive $40 million in upfront and R&D payments, up to $435 million in\nregulatory and commercial milestone payments, as well as double-digit tiered\nroyalties on U.S. net sales of alvelestat.\n* Mereo will lead the global Phase 3 study and regulatory interactions until\nstudy completion and will retain rest-of-world commercial rights for\nalvelestat.\n* On exercise of the option by Sentynl, the agreement provides funding for the\nglobal Phase 3 study, which could be initiated early in 2027.\nVantictumab (OMP18R5)\n* āshibio, Inc. (āshibio), Mereo’s development and commercial partner for\nvantictumab, is continuing to advance toward initiation of a Phase 2 clinical\ntrial in autosomal dominant osteopetrosis Type 2 (ADO2).\n* āshibio is responsible for the global clinical development of vantictumab.\nMereo has retained European commercial rights to the product, with āshibio\nholding commercial rights for the rest of the world.\nSecond Quarter 2026 Financial Results\n\nTotal research and development (“R&D”) expenses decreased by $3.6 million,\nfrom $5.4 million in the second quarter of 2025 to $1.8 million in the second\nquarter of 2026. The decrease was primarily due to a reduction of $2.6 million\nin R&D expenses for setrusumab and $1.0 million for alvelestat. The decrease\nin program expenses for setrusumab was primarily driven by reduction of, and\ndelays to, investment in manufacturing and ongoing activities, including\nmedical affairs activities in Europe during the second quarter of 2026. The\ndecrease in program expenses for alvelestat was primarily due to completion of\nactivities undertaken in preparation for the potential Phase 3 study during\n2025.\n\nGeneral and administrative (“G&A”) expenses decreased by $0.3 million,\nfrom $5.5 million in the second quarter of 2025 to $5.2 million in the second\nquarter of 2026. The decrease was primarily due to reductions of approximately\n$2.2 million driven by delays to investment in pre-commercial activities to\nlay the foundation for the potential commercial launch of setrusumab in Europe\nand other realized cost savings. These decreases were partially offset by the\nrecognition of a $1.9 million reduction in expenses in the second quarter of\n2025 for amounts received from our depository to reimburse certain expenses\nincurred by us in respect of our ADR program, whereas the corresponding amount\nin the current year was recognized in the first quarter of 2026.\n\nNet loss for the second quarter of 2026 was $7.0 million, compared to $14.6\nmillion for the second quarter of 2025, primarily reflecting reductions in R&D\nand G&A expenses and a lower net foreign currency translation loss.\n\nAs of June 30, 2026, the Company had cash and cash equivalents of $30.1\nmillion, compared to $41.0 million as of December 31, 2025. The Company\nexpects, based on current operational plans, that its existing cash and cash\nequivalents balance will enable it to fund its currently committed clinical\ntrials, operating expenses, and capital expenditure requirements into late\n2027. This guidance does not include any future potential payments associated\nwith business development activity around any of the Company’s programs.\n\nTotal ordinary shares issued as of June 30, 2026 were 798,093,044. Total ADS\nequivalents as of June 30, 2026 were 159,618,608, with each ADS representing\nfive ordinary shares of the Company. \n\nAbout Mereo BioPharma\n\nMereo BioPharma is a biopharmaceutical company focused on the development of\ninnovative therapeutics for rare diseases.

diseases, today announced financial results for the\nsecond quarter ended June 30, 2026, and provided an update on recent\ncorporate highlights.\n\nThe Company is also updating its previous cash runway guidance. As of June 30,\n2026, cash and cash equivalents were approximately $30 million, which are\nexpected to fund operations into late-2027.\n\n“The partnership with Sentynl Therapeutics which we announced earlier today\nmarks a significant milestone for our alvelestat program and for the Company\nas a whole. We are now working together to refine the design of the global\nPhase 3 study for our potential first-in-class oral therapy for AATD-LD and\nlook forward to a continued close collaboration during the short option\nperiod. Assuming exercise of the license option by Sentynl, we plan to\ninitiate the Phase 3 trial in early 2027,” said Denise Scots-Knight, Chief\nExecutive Officer of Mereo BioPharma. “Additionally, alongside our partner\nUltragenyx, we have had initial regulatory interactions on setrusumab with the\nFDA and the MHRA and we expect to be in a position to provide an update on the\npotential path forward by the end of this year. We finished the quarter with\napproximately $30 million in cash. Thanks to our careful expense management,\nwe now expect that this cash will provide runway into late-2027, exclusive of\nthe potential $40 million in upfront and R&D payments that we are eligible to\nreceive on exercise of the alvelestat option by Sentynl.”\n\nSecond Quarter 2026 Highlights, Recent Developments, and Anticipated\nMilestones \n\nSetrusumab (UX143)\n* The Orbit and the Cosmic Phase 3 studies did not achieve statistical\nsignificance against the primary endpoints of reduction in annualized clinical\nfracture rate, however, both achieved high statistical significance against\nthe key secondary endpoint of improvement in bone mineral density, as well as\nreductions in vertebral fractures and improvements in patient reported\noutcomes (PROs) associated with disease severity, pain / discomfort and daily\nactivities, with these PRO improvements achieving statistical significance in\nthe Orbit study. Setrusumab also achieved meaningful reductions in fractures\nin certain bones and in patients with higher fracture frequencies. Both\nstudies demonstrated a safety profile consistent with that observed in\nprevious trials.\n* Mereo and its partner, Ultragenyx Pharmaceutical, Inc. (Ultragenyx), are\nengaged with regulatory agencies to determine a potential path forward for\nsetrusumab in pediatric OI patients and, to-date, have held discussions with\nthe regulators in the U.S. and the U.K. The FDA indicated openness to\nconsidering alternative approaches to fracture analysis, with additional\nconversations needed to further define what additional clinical data would be\nneeded to support a potential BLA. In recent communications with the MHRA,\nthey encouraged further dialogue on any future development proposal, and we\nplan to have further interactions following the FDA discussions.\nAlvelestat (MPH-966)\n* Mereo recently announced an option and license agreement with Sentynl\nTherapeutics, Inc. (Sentynl), a wholly owned subsidiary of Zydus Lifesciences\nLimited. Sentynl has the right to acquire a license for the U.S. commercial\nand global manufacturing rights to alvelestat for AATD-LD. * Sentynl is a\nCalifornia-based, commercial-stage biopharmaceutical company with three\ncurrently approved products for rare diseases.\n* Under the agreement, the companies will collaborate to refine the design of\nthe planned global Phase 3 trial of alvelestat and to advance the\nmanufacturing during the short option period. * Mereo will receive a\nnon-refundable option fee and, on option exercise, would also be eligible to\nreceive $40 million in upfront and R&D payments, up to $435 million in\nregulatory and commercial milestone payments, as well as double-digit tiered\nroyalties on U.S. net sales of alvelestat.\n* Mereo will lead the global Phase 3 study and regulatory interactions until\nstudy completion and will retain rest-of-world commercial rights for\nalvelestat.\n* On exercise of the option by Sentynl, the agreement provides funding for the\nglobal Phase 3 study, which could be initiated early in 2027.\nVantictumab (OMP18R5)\n* āshibio, Inc. (āshibio), Mereo’s development and commercial partner for\nvantictumab, is continuing to advance toward initiation of a Phase 2 clinical\ntrial in autosomal dominant osteopetrosis Type 2 (ADO2).\n* āshibio is responsible for the global clinical development of vantictumab.\nMereo has retained European commercial rights to the product, with āshibio\nholding commercial rights for the rest of the world.\nSecond Quarter 2026 Financial Results\n\nTotal research and development (“R&D”) expenses decreased by $3.6 million,\nfrom $5.4 million in the second quarter of 2025 to $1.8 million in the second\nquarter of 2026. The decrease was primarily due to a reduction of $2.6 million\nin R&D expenses for setrusumab and $1.0 million for alvelestat. The decrease\nin program expenses for setrusumab was primarily driven by reduction of, and\ndelays to, investment in manufacturing and ongoing activities, including\nmedical affairs activities in Europe during the second quarter of 2026. The\ndecrease in program expenses for alvelestat was primarily due to completion of\nactivities undertaken in preparation for the potential Phase 3 study during\n2025.\n\nGeneral and administrative (“G&A”) expenses decreased by $0.3 million,\nfrom $5.5 million in the second quarter of 2025 to $5.2 million in the second\nquarter of 2026. The decrease was primarily due to reductions of approximately\n$2.2 million driven by delays to investment in pre-commercial activities to\nlay the foundation for the potential commercial launch of setrusumab in Europe\nand other realized cost savings. These decreases were partially offset by the\nrecognition of a $1.9 million reduction in expenses in the second quarter of\n2025 for amounts received from our depository to reimburse certain expenses\nincurred by us in respect of our ADR program, whereas the corresponding amount\nin the current year was recognized in the first quarter of 2026.\n\nNet loss for the second quarter of 2026 was $7.0 million, compared to $14.6\nmillion for the second quarter of 2025, primarily reflecting reductions in R&D\nand G&A expenses and a lower net foreign currency translation loss.\n\nAs of June 30, 2026, the Company had cash and cash equivalents of $30.1\nmillion, compared to $41.0 million as of December 31, 2025. The Company\nexpects, based on current operational plans, that its existing cash and cash\nequivalents balance will enable it to fund its currently committed clinical\ntrials, operating expenses, and capital expenditure requirements into late\n2027. This guidance does not include any future potential payments associated\nwith business development activity around any of the Company’s programs.\n\nTotal ordinary shares issued as of June 30, 2026 were 798,093,044. Total ADS\nequivalents as of June 30, 2026 were 159,618,608, with each ADS representing\nfive ordinary shares of the Company. \n\nAbout Mereo BioPharma\n\nMereo BioPharma is a biopharmaceutical company focused on the development of\ninnovative therapeutics for rare diseases.
