About Alector

Alector makes medicines to fight brain diseases. These treatments help people with Alzheimer's and Parkinson's. The company works to stop brain cells from dying.

Fighting Brain Diseases

  • Alector Brain Carrier: Proprietary technology designed to transport drugs across the blood-brain barrier, which acts as the brain's protective wall.
  • Progranulin-Elevating Antibodies: Drugs like latozinemab that increase levels of progranulin, a protein essential for brain cell health.
  • siRNA Platform: Small interfering RNA technology that stops the body from creating toxic proteins linked to dementia.
  • Enzyme Replacement Therapy: Program AL050 features an engineered enzyme intended to treat Parkinson's disease and Lewy body dementia.

Growth and Funding Deals

  • Partnered with GlaxoSmithKline in July 2021 to develop antibodies for neurodegenerative conditions.
  • Updated the GlaxoSmithKline agreement in May 2023 to share research costs for certain clinical trials.
  • Secured a $50 million loan facility from Hercules Capital in November 2024 to support operations.
  • Raised $20 million in net proceeds through a stock sale agreement with TD Securities.

How Alector Stands Out

Alector uses its brain carrier technology to bypass the brain's natural protective wall. This allows therapeutics like antibodies and enzymes to reach brain tissue more effectively.

The Quarterly Scorecard

  • Revenue was $1 million in Q1 2026, down 71.5% from $3.7 million in Q1 2025.
  • Net loss narrowed 43.3% to $22.9 million for the period ended March 31, 2026.
  • Research and development spending decreased by $15.8 million year-over-year following staff cuts in 2025.
  • Cash and marketable securities totaled $206.5 million at the end of March 2026.
  • Free cash flow improved 17.9% to negative $49.9 million in the first quarter of 2026.

Bottom Line

Alector has shifted its focus to its proprietary brain-delivery platform following recent late-stage clinical trial failures. The company maintains its operations through strategic partnerships and existing cash reserves.
