XVARY composite: 63/100 — average
Solid Biosciences develops gene therapies for Duchenne muscular dystrophy and other rare muscle and heart diseases.
You are buying 4 pipeline shots, not a sales machine. That is the whole game here, because a $570M stock can rerate on one data set while revenue stays at $0M. SGT-001 is in Phase I/II, which means early human testing. Plain English: the company is still proving the drug works and stays safe.

clinical-stage asset · $570M valuation tied to the readout
this is the only clinical-stage asset on the page, and its success or failure does most of the work behind the current $570M market value.

management plans an IND submission in late 2026, which makes this a real program but still a distant one compared with SGT-003.

Collaboration Revenue
$8M · +18%
the company generated $8M here, up 18%, but that is still support revenue rather than proof of a commercial franchise.
not the thesis
$570M
market cap
You are paying $570M for a company with $0M TTM revenue. That is a pipeline price, not a sales price.
$20M
long-term debt
Debt is only $20M, or 3% of capital. That limits leverage risk, not trial risk.
1.55
beta
A 1.55 beta means a 1% market move tends to become a 1.55% move here. You own extra volatility.
100
employees
100 employees is lean. That keeps the cost base small, but it also shows how early this business still is.
B
Strength
  • balance sheet grade B — adequate — nothing special
  • risk rank 1 — safer than 95% of stocks
  • price stability 5 / 100
  • long-term debt $20M (3% of capital)
B — functional but not a standout on the balance sheet.

The -$0.48 EPS matters because there is no sales cushion behind it.

The #1 risk here is clinical disappointment in SGT-003. This is not a diversified biotech page — one program carries most of a $570M market value.

Med
SGT-003 fails, and most of the story goes with it
The company is pre-commercial and SGT-003 is the only clinical-stage asset shown here. Negative safety or efficacy data would not trim the thesis — it would rewrite it.
Impact: this directly hits the asset supporting a $570M valuation.
Med
Runway risk does not disappear just because financing happened
The page shows a $120M cash balance and then a $240M oversubscribed financing in March 2026. That helps, but it also tells you the business still depends on external capital while product revenue remains at zero.
Impact: dilution can keep funding the science while still reducing your share of any eventual upside.
Med
Competition leaves little room for execution mistakes
The page points to a 5% estimated market share in 2026 against Sarepta. Even if the science works, Solid still has to earn relevance in a market where someone else already has scale.
Impact: the commercial win case can end up smaller than the clinical win case.
A weak readout from SGT-003 would hit the asset behind most of the $570M valuation. The March financing improves runway, but it does not turn a one-program biotech into a diversified business.

Catalyst
The next SGT-003 update
March 2026 interim data supported a planned Q1 2026 trial start. The next clinical update is the event that can move this stock the most.
Financial
Cash after the $240M raise
The page shows $120M in cash and then a March 6, 2026 financing for $240M. You want clarity on how much runway that actually buys.
Competition
Whether the 5% share assumption still looks real
The current market-share assumption is modest, but it still depends on SGT-003 staying competitive with Sarepta. In a small market, a few data points can change the whole commercial picture.
Pipeline
SGT-601 late-2026 IND timing
SGT-601 is the only visible backup plan on the page. If that late-2026 IND slips, SLDB looks even more like a one-asset company.
earnings predictability
60 / 100
in human-speak, analysts can model the losses directionally, but single-stock biotech events still create ugly surprises.
price stability
5 / 100
This stock does not trade like a steady operating business. It trades like a clinical headline waiting to happen.
