News Explained
Existing holders’ percentage ownership was diluted as common shares rose to 105,125,366 by June 30, 2026.
The August 6 release reports that Solid sold new shares through ATM sales, generating
An ATM program allows an issuer to sell new shares gradually at prevailing market prices, and issuing additional shares reduces an existing holder’s percentage ownership absent offsetting changes.
The disclosed share-count change establishes dilution for existing holders, while the release’s proceeds figures establish the cash raised; it does not provide a post-

CHARLESTOWN, Mass., Aug. 06, 2026 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB) (the “Company” or “Solid”), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, today reported financial results for the second quarter ended June 30, 2026, and provided a business update.
Bo Cumbo, President and CEO of Solid Biosciences, stated: “Our progress in the first half of 2026 positions us for continued momentum as we approach multiple key clinical and regulatory milestones across our Duchenne, Friedreich’s ataxia and broader precision genetic medicine platform over the next several quarters. In Duchenne, we continue to have confidence in SGT-003’s safety profile, which is achieved using a low-burden, steroid-only immunomodulation regimen. We are also highly encouraged by the strength of the biomarker data we have generated to date, which demonstrates promising biologic activity. As we prepare to analyze 12-month clinical data from initial participants in the INSPIRE DUCHENNE trial, we gain an important opportunity to evaluate the relationship between these biologic signals and clinical outcomes. We look forward to continued engagement with the FDA as we work with urgency to evaluate a potential accelerated approval pathway for SGT-003.”
Mr. Cumbo continued, “In FA, we continue to progress SGT-212 with two participants dosed in the FALCON clinical trial, and we look forward to sharing initial data in the first quarter of 2027, which will help inform future development pathways as we aim to bring SGT-212 rapidly to the FA patient community.”

- Cash Position: Solid had
$377.7 million in cash, cash equivalents and available-for-sale securities as of June 30, 2026, compared to$187.9 million as of December 31, 2025. The Company expects that its existing cash, cash equivalents, and available-for-sale securities will be sufficient to fund its operational runway into mid-2028. - At-the-Market (ATM) Proceeds: The
$377.7 million cash position at June 30, 2026, is inclusive of$60.8 million in net proceeds generated from ATM sales during the six months ended June 30, 2026. The Company generated an additional$15.7 million in net proceeds from ATM sales after June 30, 2026. - Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2026 were
$44.3 million , compared to$32.4 million for the second quarter of 2025. The increase of$11.9 million in research and development expenses was primarily due to a$12.2 million increase in costs for SGT-003 primarily related to manufacturing and clinical costs, a$3.2 million increase in personnel related expenses, and a$1.2 million increase in costs for SGT-212 primarily related to clinical and research costs, partially offset by a$2.2 million decrease in costs for SGT-601 related to lower manufacturing and research costs, a$1.4 million decrease in external expenses primarily related to laboratory supplies, and a$1.3 million decrease in costs for SGT-501 primarily related to lower license payments and research costs. - General and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2026 were
$13.1 million , compared to$9.3 million for the second quarter of 2025. The increase of$3.8 million was primarily due to a$2.6 million increase in personnel related costs, a$0.5 million increase in business development costs, a$0.4 million increase in equipment costs, and a$0.3 million increase in consulting services. - Net Loss: Net loss for the second quarter of 2026 was
$54.8 million , compared to a net loss of$39.5 million for the second quarter of 2025.
About SGT-003
SGT-003 is an investigational gene therapy containing a novel microdystrophin construct and a proprietary, next-generation capsid, POLARIS-101™ (formerly known as AAV-SLB101), which was rationally designed to target integrin receptors, and has shown enhanced cardiac and skeletal muscle transduction with decreased liver targeting in data from the Phase 1/2 INSPIRE DUCHENNE clinical trial and in nonclinical studies. SGT-003’s microdystrophin construct uniquely includes the R16/17 domains, which localize nNOS to the muscle. Nonclinical studies have shown that nNOS can improve blood flow to the muscle thereby reducing muscle breakdown from ischemia and muscle fatigue. Together, these design features suggest that SGT-003 could be a potential best-in-class investigational gene therapy for the treatment of Duchenne.
About the SGT-003 Development Program
The SGT-003 clinical development program consists of two multinational clinical trials – the Phase 1/2 INSPIRE DUCHENNE trial and the Phase 3 IMPACT DUCHENNE trial – which together were designed to generate a comprehensive data package to support potential global regulatory authorizations.
INSPIRE DUCHENNE is a first-in-human, open-label, single-dose, multicenter Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of a single dose of SGT-003 in pediatric participants with a genetically confirmed Duchenne diagnosis. The trial is being conducted at clinical sites in the United States, Canada, the United Kingdom and Italy.
IMPACT DUCHENNE is a Phase 3 placebo-controlled, randomized, double-blind clinical trial evaluating the efficacy of a single dose of SGT-003 in ambulatory participants with a genetically confirmed Duchenne diagnosis. Clinical trial sites are currently active in Australia and Canada, with additional clinical site activations expected in the second half of 2026, subject to site initiation activities and regulatory clearances.
About SGT-212
SGT-212 is a recombinant AAV-based gene replacement therapy for Friedreich’s ataxia (FA) designed to deliver full-length human frataxin (FXN) via a dual route of administration: intradentate nucleus (IDN) infusion, using an FDA-approved neurosurgical device in a stereotactic, precision MRI-guided technique, followed by an intravenous (IV) infusion, with the intent to increase therapeutic FXN levels in the cerebellar dentate nuclei, cardiomyocytes and other systemic tissues. Targeted delivery to the dentate nuclei will be confirmed in real time via MRI. Restoration of FXN levels is expected to repair the underlying mitochondrial dysfunction in neurons and cardiomyocytes to address neurologic, cardiac and systemic manifestations of the disease.
About the FALCON Clinical Trial
FALCON is a first-in-human, open-label, multi-center Phase 1b clinical trial designed to evaluate the safety and tolerability of SGT-212 in participants aged 18-40 who have been diagnosed with FA. FALCON is being conducted in the United States.
