Solid is heading to the New Directions Conference next week! We’re excited to share insights across Duchenne muscular dystrophy, Friedreich’s ataxia and our next-generation muscle-tropic capsid, POLARIS-101™. Be sure to connect with our team and tune into a featured presentation from our Head of Discovery and Translational Development, Nicolas Christoforou, Ph.D. #NewDirections #GeneticMedicine #Duchenne #FriedreichsAtaxia #MuscleBiology #SolidInside

We’re excited to partner with NanoMosaic through this co-marketing agreement to help advance the next generation of gene therapies. At Solid, we believe that unlocking the full potential of AAV requires not only innovative, precision capsid design, like our POLARIS-101™ next-generation platform, but also the ability to deeply understand and characterize what’s being delivered. By collaborating with NanoMosaic and their Tessie™ platform, we’re helping enable a more complete picture of AAV payloads – measuring capsid and transgene together and clearly distinguishing full, partial and empty particles. This collaboration reflects our commitment to advancing the broader gene therapy ecosystem through the development of next-generation technologies. We’re proud to work with NanoMosaic to expand access to solutions that can help usher in the next wave of precision genetic medicines.

Solid Biosciences will participate in the @Jefferies Global Healthcare Conference on June 3rd, where our President and CEO, Bo Cumbo, will take part in a fireside chat at 7:35 AM ET. Join via a live webcast: event.summitcast.com/view/Ng… #JefferiesHealthcare #GeneticMedicine #Solidinside

Solid Biosciences was proud to participate in the @DPPSpain's International Congress 2026, where Patrick Gonzalez, PhD, Vice President and Head of Clinical Science, presented on SGT-003, our next-generation investigational gene therapy for Duchenne muscular dystrophy. The presentation provided an update on SGT-003, highlighting progress from both the Phase 1/2 INSPIRE DUCHENNE and the Phase 3 IMPACT DUCHENNE clinical trials. The session underscored the continued advancement of SGT-003 and its potential to deliver meaningful impact for individuals living with Duchenne. We are grateful for the opportunity to engage with the global Duchenne community and contribute to important conversations shaping the future of gene therapy and clinical innovation. #Duchenne #GeneTherapy #DuchenneCommunity #SGT003 #RareDisease #Biotech #HealthcareInnovation #SolidBiosciences

As we come to the end of FA Awareness Month, we’re proud to stand alongside the FA community in the shared mission to cure Friedreich’s ataxia. At Solid Biosciences, we’re advancing our novel, dual-route investigational gene therapy, SGT‑212, designed to target the neurologic cardiac and systemic manifestations of Friedreich’s ataxia. We’re committed to working with patient advocacy groups to move science forward and bring meaningful therapies to those who need them most. #FriedreichsAtaxia #FACommunity #GeneTherapy #RareDisease #CommunityToCureFA

It was a privilege to connect with so many members of the gene and cell therapy community at #ASGCT2026.  We are continually inspired by our industry's shared commitment to advancing innovation for patients. Thank you to everyone who attended our presentations, exchanged insights with our team, and discussed the latest clinical advancements we’re making across our pipeline. #SolidInside #ASGCT #GeneAndCellTherapy #PrecisionGeneticMedicine #RareDisease

We are excited to share that Solid Biosciences is a proud sponsor of the @CureDuchenne 2026 FUTURES National Conference in Orlando, FL, taking place May 21–24. Our SVP of Patient Advocacy, Annie Ganot, will be presenting and we'll have an exhibit table. Please be sure to stop by to learn more about our Duchenne gene therapy program. #CureDuchenne #2026FUTURES #WeWILLCureDuchenne

In his #FierceBiotechWeek keynote, Gabriel Brooks, M.D., Solid Biosciences’ Chief Medical Officer, highlighted why delivery approaches are as critical as the therapy itself, and explored how overcoming targeting constraints can help unlock the potential of genetic medicine. Solid’s neuromuscular development programs span two complementary precision targeting strategies: molecular lock‑and‑key capsid engineering for selective tissue engagement, and precision anatomic targeting to reach specific disease drivers. Together, these strategies reflect a platform mindset -- designing therapeutic delivery around disease biology to expand the impact of genetic medicines. #PrecisionTargeting #GeneTherapy #GeneticMedicine #SolidInside

Be sure to tune in to @CureFA_org's informational webinar with Solid Biosciences for people living with Friedreich's ataxia and their families on May 26 at 12 PM ET.    This community session will cover our investigational, dual-route administration gene therapy for FA, SGT-212, and our ongoing, Phase 1b FALCON clinical trial.  Register here: us02web.zoom.us/webinar/regi… #CureFA #FriedreichsAtaxia #FACommunity #CommunityToCureFA

Today, we recognize Friedreich’s Ataxia Awareness Day and the strength of the FA community. We are privileged to highlight two families living with FA, and the hope and support they draw from those around them. At Solid Biosciences, their resilience fuels our commitment to making meaningful progress. We are advancing SGT-212, our investigational, dual-route administration gene therapy for FA, which is being evaluated in the ongoing Phase 1b FALCON clinical trial. We are proud to stand alongside advocacy partners like Friedreich's Ataxia Research Alliance (FARA) and the @NAF_Ataxia, among others, to further support patients and families impacted by FA. Thank you Marinda Cauley, Liam Cauley, Marcy Freed, and Greyson Freed for helping us raise awareness for FA. #FAAwarenessDay #CureFA #FriedreichsAtaxia #FACommunity
