Exhibit 99.1 DIANTHUS THERAPEUTICS HIGHLIGHTS RECENT BUSINESS ACHIEVEMENTS AND REPORTS Q2 2026 FINANCIAL RESULTS Advancing a neuromuscular franchise with claseprubart, a highly potent investigational classical pathway inhibitor, with best-in-disease potential across generalized M
How this was made
The 30-second read
Why it matters
Key trading focus is the combination of (1) a specific interim efficacy signal in CIDP (75% response in first 40), (2) safety observations (no related serious infections, no DIL/SLE to date), (3) FDA feedback that removes ANA screening criteria and routine ANA testing, and (4) explicit upcoming milestones (CAPTIVATE Part B guidance by YE’26, EMERGE top-line in 2H’28, MMN top-line in Dec ’26) plus cash of about $1.2B as of June 30, 2026.
Market read
The filing provides fresh, tradable catalysts: interim Phase 3 response rate, FDA protocol alignment, enrollment completion, and a stated cash runway into 2030.
What to watch
The filing does not provide full financial detail in the excerpt (beyond cash runway), and trial endpoints, effect sizes, and statistical robustness for CAPTIVATE Part A are not fully quantified here.
Background
This is an SEC Form 8-K (Item 2.02) with Q2 2026 financial results and a pipeline update for claseprubart, DNTH212, and DNTH312.
Ticker impact
Dianthus reports Q2 2026 results and updates claseprubart Phase 3 CAPTIVATE interim response (75% in first 40) plus MMN enrollment and cash runway.
Near-term upside bias as traders focus on CAPTIVATE Part B guidance by YE’26 and EMERGE top-line timing in 2H’28, tempered by biotech execution risk.
The filing is a primary disclosure (8-K with results and program updates) and includes specific interim efficacy and safety statements, plus explicit timing for upcoming guidance and cash balance.
Market effects
Adds incremental sentiment to complement-targeting and autoimmune biotech pipelines, but impact is company-specific rather than sector-wide.
Primarily affects US small/mid-cap biotech sentiment; limited direct regional spillover.
Global trial execution updates (China Phase 1 for DNTH212, global MMN trial) may modestly influence international biotech risk appetite.
Counterpoint
Interim responder analysis from only the first 40 participants may not translate into Part B success; timing gaps (YE’26 and 2H’28) reduce immediacy.
