What Amylyx Pharmaceuticals, Inc. reported on August 6, 2026

The quarter ending December 31, 2025, against the same quarter a year earlier.

These are single quarters, not a trailing year — the figures elsewhere on this site cover twelve months and will be much larger. A seasonal business swings a long way between the two: ServiceNow earns $2.0B of free cash flow in its December quarter and $0.5B in its June one.

Compared against the same quarter a year earlier, not against an analyst forecast. A “beat” or “miss” needs a consensus estimate, which is licensed data we do not carry — and getting it wrong is worse than leaving it out.

What management said

“With the last participant’s final study visit recently completed, we are eagerly anticipating the expected topline data readout of the pivotal Phase 3 LUCIDITY trial in post-bariatric hypoglycemia in late August or early September,”

What Amylyx Pharmaceuticals, Inc. does

Avexitide is an investigational, first-in-class glucagon-like peptide-1 (GLP-1) receptor antagonist that has been evaluated in five Phase 1 and Phase 2 clinical trials for post-bariatric hypoglycemia (PBH) and has also been studied in congenital hyperinsulinism (HI). The U.S. Food and Drug Administration (FDA) has granted avexitide Breakthrough Therapy Designation for both indications, Rare Pediatric Disease Designation in congenital HI, and Orphan Drug Designation for the treatment of hyperinsulinemic hypoglycemia (which includes PBH and congenital HI). In PBH, an exaggerated GLP-1 response leads to excessive insulin secretion, resulting in recurrent hypoglycemic events. Avexitide is a GLP-1 receptor antagonist designed to competitively bind to the GLP-1 receptor on pancreatic islet beta cells and inhibit the exaggerated GLP-1-driven insulin response characteristic of PBH, reducing inappropriate insulin secretion and stabilizing blood glucose levels. In two Phase 2 PBH clinical trials, avexitide demonstrated highly statistically significant reductions in hypoglycemic events.
