Simply Wall St · 2d ago

MoonLake Immunotherapeutics (MLTX) has drawn fresh attention after reporting third quarter and nine month 2026 results, with net losses widening even as loss per share from continuing operations narrowed compared with the prior year quarter.

MoonLake Immunotherapeutics shares have been volatile, with a 16.08% 30 day share price return and a 7.35% gain over the past week, but a 27.10% decline over 90 days at a last close of US$12.56.
