Amylyx Pharmaceuticals, Inc.
After carefully weighing both arguments, the bear case is significantly more compelling. While the bull thesis correctly identifies deep value characteristics and downside protection from cash holdings, it fundamentally misunderstands the scientific implications of the PHOENIX trial failure. The core mechanism of AMX0035 targeting mitochondrial dysfunction and ER stress failed definitively in ALS, and these same pathways are common across neurodegenerative diseases. The probability that this mechanism will succeed in the more complex Alzheimer's pathology is extremely low. The bull case's reliance on liquidation value as downside protection ignores the reality of biotech wind-down costs and the cash burn dynamics that will destroy value even before liquidation. Management integrity, while admirable, doesn't overcome scientific failure. The acquisition thesis lacks credibility given that strategic buyers avoid failed mechanisms and damaged scientific credibility. The asymmetric risk-reward strongly favors the short side, with limited upside (even in best case scenarios) versus substantial downside as the Alzheimer's program likely fails and cash burns toward zero.

Amylyx Pharmaceuticals represents the rare intersection of genuine deep value and asymmetric upside that emerges when markets completely abandon a fundamentally misunderstood situation. The October 2024 voluntary withdrawal of Relyvrio from the ALS market—following a failed Phase 3 confirmatory trial—has created what Benjamin Graham would recognize as a classic "cigar butt" opportunity, but with a critical twist: this company possesses hidden optionality that the market is pricing at zero.
The investment case rests on three pillars that the market is systematically undervaluing: a robust balance sheet trading below liquidation value, a misunderstood Alzheimer's program with billion-dollar potential, and management integrity that paradoxically creates acquisition appeal in an industry notorious for ethical shortcuts.
At current levels, Amylyx trades at approximately 0.8x tangible book value, placing it firmly in Graham's net-net category. The company reported $364 million in cash and equivalents as of their last filing, against total liabilities of roughly $85 million, yielding net current assets of approximately $279 million. With a current market capitalization of roughly $240 million, investors are essentially purchasing the company's cash pile at a 14% discount while receiving the Alzheimer's program, intellectual property portfolio, and regulatory expertise for free.
This liquidation value floor provides exceptional downside protection. Even in a worst-case scenario where the Alzheimer's program fails completely, the company could return approximately $9-11 per share to shareholders through orderly liquidation, representing 13-38% upside from current levels with minimal execution risk.
The cash runway extends through 2026 based on current burn rates, providing ample time for value realization events without the dilutive equity raises that plague most biotech investments. This financial cushion transforms what appears to be a distressed situation into a well-capitalized option on multiple value catalysts.
The market's conflation of ALS and Alzheimer's pathology represents a fundamental analytical error that creates the core investment opportunity. While both are neurodegenerative diseases, their underlying mechanisms differ substantially. ALS primarily affects motor neurons through protein aggregation and oxidative stress, while Alzheimer's involves complex interactions between amyloid plaques, tau tangles, and neuroinflammation across multiple brain regions.
AMX0035's dual mechanism—combining sodium phenylbutyrate (a histone deacetylase inhibitor) with taurursodiol (an endoplasmic reticulum stress reducer)—targets mitochondrial dysfunction and cellular stress pathways that may prove more relevant in Alzheimer's pathophysiology. The ongoing PEGASUS Phase 2 trial in mild Alzheimer's disease represents a $2-4 billion net present value opportunity if successful, based on comparable Alzheimer's drug valuations.
Recent Alzheimer's approvals like Aduhelm (despite its controversies) and Leqembi have established precedent for FDA acceptance of modest cognitive benefits in this indication. AMX0035's combination approach could potentially demonstrate superior efficacy to monotherapies by addressing multiple pathological pathways simultaneously. Even modest success—defined as statistically significant improvement on cognitive assessments—would likely drive the stock to $20-30 range based on peak sales projections of $1-2 billion annually.
The binary nature of this catalyst creates exceptional risk-adjusted returns. PEGASUS trial readout, expected in late 2025, provides a clear timeline for value realization. Success probability, while difficult to quantify given the ALS failure, may be higher than the market's implied 10-15% based on the differentiated pathology and mechanism of action.
Amylyx's voluntary withdrawal of Relyvrio—foregoing hundreds of millions in potential revenue—represents unprecedented integrity in biotechnology. This decision, while immediately destructive to shareholder value, establishes management credibility that commands premium valuations in strategic transactions.
Large pharmaceutical companies increasingly value ethical management teams following numerous industry scandals. Amylyx's demonstrated willingness to prioritize patient outcomes over short-term profits makes them an attractive acquisition target for companies seeking to enhance their reputational capital. This "integrity premium" could drive acquisition multiples 30-50% above comparable distressed biotech transactions.
Strategic acquirers would gain not only the Alzheimer's program but also proven regulatory expertise, established clinical trial infrastructure, and management talent with demonstrated FDA navigation capabilities. The company's accelerated approval experience with Relyvrio, despite the ultimate outcome, provides valuable institutional knowledge worth significant premiums in strategic transactions.
Multiple acquisition scenarios create additional value realization pathways beyond the Alzheimer's program success. Large pharmaceutical companies face mounting pressure to replenish pipelines as patent cliffs approach major revenue drivers. Amylyx's combination therapy platform, regulatory relationships, and clinical expertise represent strategic assets that could command $15-20 per share in acquisition scenarios.
The company's intellectual property portfolio around combination therapies for neurodegeneration provides defensive value and potential licensing opportunities. Even failed programs generate valuable data that can inform future development efforts, creating option value that the market currently prices at zero.
Tax considerations further enhance acquisition appeal. Amylyx's significant net operating losses could provide substantial tax benefits to profitable acquirers, effectively subsidizing acquisition premiums through reduced tax liabilities.
This investment requires careful risk management given the binary nature of biotech catalysts. The recommended 2-3% position size reflects high conviction in the asymmetric risk-reward profile while acknowledging execution risks inherent in drug development.
Key risks include Alzheimer's trial failure, management departure, and potential dilutive financings if cash burn accelerates. However, the strong balance sheet and clear catalyst timeline mitigate many traditional biotech risks. The liquidation value floor provides exceptional downside protection rarely available in growth-oriented biotech investments.
Monitoring metrics include cash burn rates, clinical trial enrollment progress, and competitive landscape developments in Alzheimer's disease. Any positive interim data or partnership announcements could drive immediate revaluation toward fair value estimates.
Amylyx Pharmaceuticals represents the rare convergence of deep value characteristics with transformational upside optionality. The market's emotional reaction to the Relyvrio withdrawal has created a classic contrarian opportunity where patient capital can generate exceptional returns through multiple value realization pathways.
The combination of liquidation value downside protection, billion-dollar Alzheimer's optionality, and acquisition premium potential creates risk-adjusted return profiles rarely available in public markets. While the investment requires tolerance for binary outcomes and extended holding periods, the asymmetric payoff structure justifies concentrated position sizing for investors capable of withstanding volatility.
This opportunity exemplifies Graham's principle that the market's short-term voting machine behavior creates long-term weighing machine profits for disciplined value investors willing to act when others cannot.

The bullish narrative surrounding Amylyx Pharmaceuticals represents a dangerous conflation of management ethics with investment merit. While the voluntary withdrawal of Relyvrio may demonstrate admirable scientific integrity, it simultaneously exposes the fatal flaw in the company's core value proposition: their lead mechanism of action has been definitively proven ineffective in human neurodegenerative disease.
The market's current valuation of approximately $240 million assumes that lightning can strike twice—that the same combination therapy that failed catastrophically in ALS will somehow succeed in Alzheimer's disease. This assumption ignores fundamental neurobiology, statistical probability, and the harsh realities of biotech investing. Amylyx represents a classic value trap where apparent deep value metrics mask an inexorable march toward zero.
The core investment thesis collapse begins with the uncomfortable truth about AMX0035's mechanism of action. The combination of sodium phenylbutyrate and taurursodiol targets mitochondrial dysfunction and endoplasmic reticulum stress—pathways that are common to virtually all neurodegenerative diseases, not unique to ALS.
The PHOENIX Phase 3 trial didn't fail due to ALS-specific factors; it failed because the fundamental hypothesis about mitochondrial protection in neurodegeneration was wrong. The 48-week study with 664 patients provided definitive evidence that this mechanism cannot meaningfully alter disease progression in human neurodegenerative conditions. The statistical power was more than adequate to detect clinically meaningful effects, yet the results showed no benefit whatsoever.
This failure has profound implications for the Alzheimer's program that bulls systematically ignore. While ALS and Alzheimer's differ in their initiating pathologies, both diseases share the downstream mitochondrial dysfunction and cellular stress pathways that AMX0035 purports to address. If the drug cannot protect neurons from death in ALS—where the pathological cascade is relatively straightforward—the probability of success in Alzheimer's, with its vastly more complex multi-pathway pathology, approaches zero.
The PEGASUS trial in Alzheimer's represents a desperate attempt to salvage value from a fundamentally flawed therapeutic approach. Management's continued pursuit of this program despite the ALS failure suggests either scientific denial or deliberate shareholder deception to maintain funding runway.
Bulls tout the company's $364 million cash position as providing downside protection, but this analysis ignores the accelerating cash burn that accompanies clinical failure. The company's quarterly burn rate has averaged $40-50 million, translating to an 18-24 month runway under current operations. However, this calculation assumes static expenses when the reality involves escalating costs from the ongoing Alzheimer's trial, increased regulatory expenses, and the operational overhead of maintaining a public company infrastructure with no revenue prospects.
More critically, the cash pile represents a melting ice cube with no replenishment mechanism. The Relyvrio withdrawal eliminated any near-term revenue potential, while the damaged credibility from the ALS failure makes equity fundraising prohibitively dilutive. Any future capital raises will occur at substantial discounts to current levels, creating a vicious cycle of dilution that destroys per-share value even if absolute cash balances temporarily increase.
The liquidation value analysis that bulls rely upon fails to account for the substantial costs associated with winding down clinical operations, satisfying regulatory obligations, and managing the complex legal and financial structures of a failed biotech company. Historical precedent suggests that biotech liquidations typically recover 60-70% of stated cash values after accounting for wind-down costs, professional fees, and operational commitments. This reality transforms the supposed $11 per share liquidation value into a more realistic $6-7 range, providing minimal downside protection at current levels.
The Alzheimer's drug development landscape represents one of the most efficient value destruction mechanisms in modern capitalism. Over the past two decades, pharmaceutical companies have invested hundreds of billions of dollars in Alzheimer's research with virtually nothing to show for it beyond Aduhelm's controversial approval and Leqembi's marginal benefits.
The fundamental challenge in Alzheimer's drug development isn't merely scientific—it's mathematical. The disease's complex, multi-factorial pathology means that any single intervention faces overwhelming odds of failure. AMX0035's combination approach, while theoretically appealing, targets pathways that are downstream consequences rather than root causes of Alzheimer's pathology. Even if the drug successfully reduces mitochondrial dysfunction and ER stress, these improvements may prove irrelevant to clinical outcomes in a disease driven by amyloid accumulation, tau pathology, and neuroinflammation.
The recent modest successes with anti-amyloid therapies like Leqembi actually work against AMX0035's prospects by establishing a new standard of care that targets disease-specific pathology rather than generic neuroprotection. Regulatory agencies and physicians increasingly expect Alzheimer's treatments to demonstrate mechanism-specific benefits, not just theoretical neuroprotection that has failed repeatedly across multiple disease contexts.
PEGASUS trial design further undermines success probability. The study's endpoints rely on cognitive assessments that are notoriously variable and subject to placebo effects. Even if AMX0035 demonstrates statistical significance on some measures, the clinical meaningfulness of any improvements remains highly questionable given the drug's failure to show benefits in the more straightforward ALS indication.
The market's positive interpretation of management's Relyvrio withdrawal represents a fundamental misunderstanding of biotech investment dynamics. While the decision may demonstrate scientific integrity, it simultaneously reveals management's inability to generate shareholder value from their core assets.
Effective biotech management requires the ability to navigate regulatory challenges, optimize clinical trial design, and maximize commercial potential from approved products. Amylyx's management demonstrated failure across all these dimensions. The initial accelerated approval of Relyvrio based on inadequate Phase 2 data suggests poor clinical development strategy, while the subsequent Phase 3 failure indicates fundamental misunderstanding of their own drug's mechanism and patient population.
The voluntary withdrawal, while ethically commendable, represents the ultimate admission of management incompetence. Successful biotech companies find ways to salvage value even from challenging regulatory situations through indication expansion, combination strategies, or partnership arrangements. Amylyx's immediate capitulation suggests a management team that lacks the creativity and persistence necessary for biotech success.
This management track record becomes particularly concerning when evaluating the Alzheimer's program. The same team that misread ALS pathology and clinical trial design now asks investors to trust their judgment in an even more complex therapeutic area. The probability of execution success approaches zero when management has already demonstrated fundamental incompetence in their core competency.
Bulls frequently cite acquisition potential as a downside protection mechanism, but this analysis ignores the realities of pharmaceutical M&A. Strategic acquirers seek assets that enhance their competitive position, not failed programs that carry substantial reputational risk.
Amylyx's damaged scientific credibility makes them radioactive to potential acquirers. The Relyvrio failure raises fundamental questions about the company's research capabilities, clinical development expertise, and regulatory strategy. No major pharmaceutical company wants to inherit these liabilities, particularly when the core mechanism has been definitively disproven in human trials.
The intellectual property portfolio that bulls tout as valuable actually represents a liability in acquisition scenarios. Patents around failed mechanisms provide no competitive advantage and may actually impede future research by creating freedom-to-operate issues. Strategic buyers increasingly avoid acquiring failed IP portfolios that could complicate their own development efforts.
Tax benefits from net operating losses provide minimal acquisition incentive given the relatively small size of Amylyx's losses compared to major pharmaceutical companies' tax obligations. The administrative burden and reputational risk of acquiring a failed biotech far outweigh any potential tax advantages.
The investment case against Amylyx doesn't rely on a single failure mode but rather the convergence of multiple destructive forces that make recovery virtually impossible. The scientific failure of their core mechanism eliminates any realistic path to product revenue, while the cash burn dynamic ensures continuous dilution and eventual bankruptcy absent miraculous clinical success.
The Alzheimer's trial represents the company's final roll of the dice, but the odds are overwhelmingly against success. Even in the unlikely event of positive results, the regulatory pathway for approval remains treacherous given the ALS failure and FDA's increasing skepticism toward marginal Alzheimer's treatments.
Market dynamics further compound these challenges. The biotech sector's risk appetite has contracted significantly following numerous high-profile failures, making it increasingly difficult for companies like Amylyx to access capital markets. The window for speculative biotech investments has largely closed, leaving Amylyx stranded without viable funding alternatives.
The most likely scenario involves continued cash burn through 2025, followed by increasingly desperate attempts to raise capital at progressively lower valuations. The Alzheimer's trial failure—which represents the highest probability outcome—will trigger a final collapse in valuation as the last vestiges of hope disappear.
Amylyx Pharmaceuticals represents everything wrong with applying traditional value investing principles to biotech companies without understanding the underlying science and regulatory dynamics. The apparent deep value characteristics mask a fundamentally worthless asset that will methodically destroy shareholder capital over the coming months.
The company's trajectory toward zero is not a matter of speculation but mathematical certainty given the combination of proven mechanism failure, unsustainable cash burn, and absence of viable strategic alternatives. Investors clinging to liquidation value analysis or acquisition fantasies will discover that biotech value traps can be far more destructive than traditional industrial value traps because the underlying assets have no salvage value whatsoever.
The current price of $7.99 represents not an opportunity but a trap for investors who mistake management integrity for investment merit. The inexorable decline toward $2-4 per share over the next 12-18 months offers one of the most asymmetric short opportunities in the current market, where the maximum gain potential far exceeds the limited upside risk.
