DM1 and FSHD Phase 1/2 cohort readouts • 2026-12-31

Base target: $19 / p=50% prob

Biggest risk

Q2 total revenue fell 34% year over year, and 2026 net product revenue guidance was narrowed to $1.2–$1.3 billion from $1.2–$1.4 billion. ELEVIDYS safety restrictions and the limits of small, externally controlled analyses could constrain uptake or confidence.

Invalidation

Break below $9 or thesis failure.

What would change my mind?

The September ELEVIDYS findings support the ambulatory evidence base, while positive DM1 or FSHD data could broaden the pipeline thesis. Sarepta reported $328.7 million of Q2 net product revenue and GAAP operating profit.

Commentary

Company-reported September clinical data support a cautiously positive news tone, but a verified post-release share-price reaction, social coverage, options skew and short-interest readings are unavailable; zero sentiment-field values denote unavailable data, not neutral measurements. [#PR-2026-09-30] https://investorrelations.sarepta.com/node/25481 The September 23 settlement excerpt says each party bears its own litigation costs but does not establish a material operating effect. [#8-K-2026-09-23] https://www.sec.gov/Archives/edgar/data/873303/000119312526399416/srpt-20260923.htm The deterministic prior is positive, but low coverage, safety risk and limited direct-peer evidence keep conviction moderate.

DM1 and FSHD Phase 1/2 cohort readouts
Sarepta said multiple-ascending-dose cohort readouts for its DM1 and FSHD studies remained on track for the second half of 2026. Safety and the strength of the results, rather than the timetable alone, will determine their significance. [#SEC-8K-2026-08-05] https://www.sec.gov/Archives/edgar/data/873303/000119312526335056/srpt-ex99_1.htm

Short-term Catalysts

Next few weeks

Market assessment of ELEVIDYS data
2026-10-31
Sarepta reported two-year functional benefits in 25 patients treated at ages 8–12 versus 99 matched external controls, with no new safety signal in that analysis. The small treated group and external-control design limit the inference; the next test is whether the evidence changes clinical confidence or uptake.

Sarepta expected full Cohort 8 enrollment by year-end 2026 and 12-week data from the full cohort in Q1 2027. Early biomarker and safety findings would add evidence but would not alone establish long-term functional benefit.

Lower ELEVIDYS sales contributed to the year-over-year Q2 revenue decline, while narrowed product-revenue guidance leaves execution risk. [#SEC-8K-2026-08-05] https://www.sec.gov/Archives/edgar/data/873303/000119312526335056/srpt-ex99_1.htm
The older-ambulatory ELEVIDYS analysis has only 25 treated patients and uses matched external controls; results may not translate into sustained commercial uptake. [#PR-2026-09-30] https://investorrelations.sarepta.com/node/25481
