Alpha Cognition Inc. (the “Company,” “Alpha Cognition,” “we,” or us”) is a biopharmaceutical company dedicated to developing treatments for patients suffering from neurodegenerative diseases, such as Alzheimer’s disease (“Alzheimer’s disease” or “AD”), for which there are limited or no treatment options. On July 26, 2024, the Company received approval by the FDA of the Company’s New Drug Application (the “NDA”) for ZUNVEYL™ (benzgalantamine) previously known as ALPHA-1062 (“ZUNVEYL” or “ALPHA-1062”) a delayed release oral tablet formulation indicated for the treatment mild to moderate dementia of the Alzheimer’s type in adults (Alzheimer’s disease). The Company’s current focus is on the commercial manufacturing and sales of ZUNVEYL oral tablet formulation.

We are a biopharmaceutical company focused on discovering, developing, and commercializing potential best-in-class medicines for serious and rare diseases. We target disease areas where marketed therapies often leave room for improvements in efficacy, safety, and/or dosing convenience. We believe that first-generation medicines rarely represent optimal solutions, especially in rare disease areas, and that there is potential to develop differentiated, best-in-class medicines that could lead to improved patient outcomes, reduced side effects, improved quality of life, expanded market access, and augmented market competition.
We believe this strategy reduces the risks associated with discovering and developing novel therapeutics. Development of Therapies to Treat Thyroid Eye Disease (TED) We are developing therapies for the treatment of TED, a serious and debilitating rare autoimmune disease that causes inflammation within the orbit of the eye that can cause bulging of the eyes, redness and swelling, double vision, pain, and potential blindness. TED significantly impacts quality of life, imposing a high burden on activities of daily living and mental health for patients suffering from the disease. TED is a progressive disease consisting of an initial active phase (“active TED”), followed by a transition to a secondary chronic phase (“chronic TED”).

We believe that first-generation medicines rarely represent optimal solutions, especially in rare disease areas, and that there is potential to develop differentiated, best-in-class medicines that could lead to improved patient outcomes, reduced side effects, improved quality of life, expanded market access, and augmented market competition.
We believe that there are multiple opportunities to develop fast-follower therapeutics that improve on teprotumumab’s features, including dosing schedule, route of administration, and safety profile. We are developing two product candidates, veligrotug (formerly known as VRDN-001) for intravenous (“IV”) and VRDN-003 for subcutaneous (“SC”) administration, to treat patients who suffer from TED. Our most advanced program, veligrotug, is a differentiated humanized monoclonal antibody targeting IGF-1R intravenously administered for the treatment of TED. In previously presented in vitro nonclinical data, we showed that veligrotug is a potentially differentiated full antagonist of IGF-1R, compared to teprotumumab’s incomplete antagonism of IGF-1R. VRDN-003 has the same binding domain as veligrotug, and was engineered to have a longer half-life.

We prioritize product concepts that are aligned with clinical and commercial hypotheses, which we expect will provide an attractive balance of risk and opportunity, thereby representing a compelling allocation of our resources. We focus on advancing therapeutic proteins that we either in-license or discover internally, incorporating proprietary therapeutic protein and antibody discovery and optimization platforms to advance clinical candidates with unique characteristics.

In addition to developing therapies for TED, we are also developing a portfolio of engineered FcRn inhibitors, including VRDN-006 and VRDN-008. FcRn inhibitors have the potential to treat a broad array of autoimmune diseases, representing a possible significant commercial market opportunity. Our multi-pronged engineering approach has resulted in a portfolio of FcRn-targeting molecules that leverage the clinically and commercially validated mechanism of FcRn inhibition while potentially addressing the limitations of current agents such as incomplete immunoglobulin G (“IgG”) suppression, safety, and inconvenience of dosing. VRDN-006 is a highly selective Fc fragment that inhibits FcRn and is designed to be a convenient subcutaneous and self-administered option for patients.
As a result, we have the flexibility to develop and potentially commercialize products ourselves, or alternatively to enter collaborations with industry partners. •Advance our portfolio of FcRn inhibitors with the potential to treat a broad array of autoimmune disorders.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-11-11. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
