Simplify's take

What believers are saying

  • October 2026 raised $75 million and Genentech delivered $100 million upfront cash.
  • Management said liquidity now funds operations into the second half of 2029.
  • AL137 targets first-in-human dosing in Australia by April 2027, creating a near-term catalyst.

What critics are saying

  • GSK terminates the collaboration January 2, 2027, erasing latozinemab and nivisnebart economics.
  • October 2025 layoffs cut about 47% of staff, signaling a broken operating model.
  • AL137 lacks clinical proof; another failure would force more dilution or platform retrenchment.

What makes Alector unique

  • ABC blood-brain barrier platform drives antibodies, enzymes, and siRNA across the brain.
  • Genentech licensed AL050 on October 5, 2026, validating Alector's delivery science.
  • AL137, AL164, and AL062 target Alzheimer’s, tau, and alpha-synuclein through one platform.

Alector Inc. reported third-quarter net income of $124.6 million on Thursday, compared with a loss in the same period a year earlier. The South San Francisco-based biotechnology company earned $1.11 per share. Analysts surveyed by Zacks Investment Research had expected a loss of 23 cents per share. Revenue for the quarter was $162.9 million. Alector's shares hit $2.09 in the final minutes of trading on Thursday, up from $1.26 a year ago.

Alector shares gain 49.3% in a year despite Q2 revenue falling to $3.3M

Alector shareholders earned a 49.3% return over the past year, including dividends. The shares cost $1.48 at the start of the period and now trade at $2.15. Second-quarter 2026 revenue fell to $3.32 million from $7.874 million a year earlier. The net loss narrowed to $22.99 million from $30.524 million. Optimists saw a fair value of $3.83, assuming revenue growth of 64.8% a year and an 18.8% profit margin if late-stage latozinemab data supported commercial success. Pessimists saw $1, expecting revenue to fall 43.3% a year and a very small market for FTD GRN, a rare form of dementia. The latest results cut both ways. They challenge the steep revenue ramp, and the shift to profit remains unproven.

Alector enters global license agreement with Genentech for brain penetrant GCase Enzyme Replacement Therapy for Parkinson's Disease and other neurodegenerative diseases.

Alector enters global license agreement with Genentech for brain penetrant GCase Enzyme Replacement Therapy for Parkinson's Disease and other neurodegenerative diseases. October 05, 2026 07:00 ET | Source: Alector, Inc. Alector grants Genentech exclusive rights to develop and commercialize AL050, an investigational GCase Enzyme Replacement Therapy (ERT) enabled by Alector Brain Carrier (ABC), Alector's proprietary blood-brain barrier delivery platform Alector to receive $100 million upfront payment, with potential for up to $1.17 billion in additional milestone payments, as well as tiered royalties on net sales SOUTH SAN FRANCISCO, Calif., Oct. 05, 2026 (GLOBE NEWSWIRE) - Alector, Inc. (Nasdaq: ALEC), a biotechnology company focused on developing therapies to counteract the devastating progression of neurodegeneration, today announced it has entered into an exclusive global licensing agreement with Genentech, a member of the Roche Group, granting Genentech worldwide rights to develop and commercialize Alector's AL050 program, its brain-penetrant engineered glucocerebrosidase (GCase) ERT. AL050 is designed to address GCase deficiency, a driver of neurodegeneration in Parkinson's Disease that is most pronounced in - but not limited to - carriers of GBA1 mutations. It combines an Alector-engineered GCase, optimized for greater enzymatic activity and a longer half-life, with Alector's ABC, which is designed to transport therapeutics across the blood-brain barrier. Delivered into the brain, the enzyme is intended to break down glucosylsphingosine and glucosylceramide, lipids that accumulate in neurons and other brain cells upon GCase deficiency and contribute to neurodegeneration, with the aim of reducing cellular dysfunction and slowing disease progression. "Deficient GCase activity is increasingly recognized as a contributor to Parkinson's Disease, and there is still no approved therapy that addresses the underlying enzyme deficiency," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. "The challenge in treating GCase deficiency is twofold: engineering an enzyme with optimal activity and durability and successfully delivering it to the brain. AL050 addresses this by pairing an engineered GCase enzyme with our proprietary Alector Brain Carrier technology designed to cross the blood-brain barrier. Genentech's long-standing commitment to Parkinson's Disease makes them an ideal partner as this program moves toward the clinic". "Parkinson's Disease is one of the fastest-growing neurological conditions worldwide," said Boris L. Zaïtra, Head of Roche Corporate Business Development. "By partnering with companies such as Alector we aim to delay or halt the progression of Parkinson's so patients maintain and prolong their independence." Under the terms of the agreement, Alector will receive an upfront payment of $100 million and is also eligible to receive additional payments of up to $1.17 billion upon the achievement of development, regulatory, and commercial milestones. Alector is also eligible for tiered royalties on net sales. Under the collaboration, Genentech will be responsible for development, regulatory, manufacturing, and commercialization across all indications. Alector retains ownership of ABC and full rights to apply the platform across its wholly owned pipeline. "This partnership extends our cash runway into 2029, providing resources to advance our fully active, subcutaneously delivered, brain-enabled anti-Aβ antibody to multi-cohort clinical data in Alzheimer's patients, and move our subcutaneously delivered, brain-enabled Tau siRNA and alpha- synuclein siRNA programs through IND-enabling studies and to IND filings," said Dr. Rosenthal. Alector R&D Webinar on Wholly Owned Pipeline Alector will host a scientific webinar on Tuesday, October 13th, 2026, at 8:00 a.m. PT, focused on AL137, its brain-enabled anti-Aβ antibody; AL164, its tau siRNA program; and AL062, its alpha-synuclein siRNA program. Registration and webcast information will be available on the Events and Presentations page of the Alector corporate website.
