Bristol Myers Squibb and the Billion Dollar Schizophrenia Bet

The Market is a Cold Judge

The numbers do not lie, but they often deceive. On this Monday morning, October 27, 2025, Bristol Myers Squibb (BMY) finds itself in a peculiar purgatory. While the broader S&P 500 has flirted with record highs over the last 48 hours, BMY shares remain tethered to a valuation that suggests a company in terminal decline. The ticker is hovering at $53.82, a price that implies the market views its future cash flows with deep suspicion. This is the ‘Valley of Death’ in pharmaceutical investing. It is the gap between the expiration of legacy patents and the uncertain ramp-up of new blockbusters.

Wall Street is currently pricing BMY at a forward price-to-earnings (P/E) ratio of just 8.4x. To put that in perspective, the healthcare sector average sits north of 18x. Per the latest Reuters sector analysis, investors are fleeing traditional ‘value’ pharma for the high-octane growth of GLP-1 weight loss drugs. Bristol Myers Squibb is not in the weight loss business. It is in the brain business, and that is where the narrative shifts from risk to potentially massive reward.

The Patent Cliff and the Revenue Gap

The math is brutal. Between now and 2030, Bristol Myers Squibb faces a loss of exclusivity (LOE) on products representing nearly $25 billion in annual revenue. This includes the anticoagulation giant Eliquis and the oncology powerhouse Opdivo. In the Q3 2025 10-Q filing released last week, the company confirmed that Eliquis revenue grew 4% year-over-year to $3.1 billion, but the shadow of the Inflation Reduction Act (IRA) price negotiations looms large. The market is not rewarding current sales; it is discounting the 2026 price cuts.

Management is fighting back with a portfolio of ‘New Product’ assets. These include Camzyos for obstructive hypertrophic cardiomyopathy and Sotyktu for psoriasis. In the quarter ending September 30, 2025, this new portfolio generated $1.4 billion in revenue, a 62% increase from the previous year. However, this growth is still not enough to fill the $25 billion crater left by the upcoming patent expirations. The missing piece of the puzzle is KarXT, now marketed as Cobenfy.

The Cobenfy Catalyst

Cobenfy is the first truly new mechanism for treating schizophrenia in over five decades. It does not block dopamine receptors like traditional antipsychotics, which means it avoids the debilitating side effects of weight gain and motor tremors. Since its launch in late 2024, the uptake has been aggressive. According to Bloomberg market data from the weekend, Cobenfy prescriptions for Q3 2025 reached 145,000, significantly outpacing the consensus estimate of 110,000.

This is the proprietary metric that the market is ignoring. If Cobenfy can achieve a 15% share of the treated schizophrenia population in the US, it becomes a $6 billion to $8 billion annual asset. When combined with the $4 billion peak potential of Camzyos, the revenue gap begins to close. The risk, however, is the high cost of the launch. Bristol Myers Squibb’s SG&A expenses rose 7% this quarter as they deployed a massive specialized sales force to reach psychiatric clinics. The reward is a high-margin, long-duration asset that is protected by patents well into the late 2030s.

Financial Performance Breakdown

To understand the disconnect, one must look at the cash flow. Bristol Myers Squibb generated $3.8 billion in free cash flow this quarter alone. They are using this capital to defend their dividend, which currently yields a hefty 4.45%. For the income investor, BMY is a fortress. For the growth investor, it is a riddle.

MetricQ3 2024 ActualQ3 2025 ActualYear-over-Year Change
Total Revenue$10.96B$11.82B+7.8%
New Product Portfolio$0.92B$1.49B+62%
Free Cash Flow$3.51B$3.88B+10.5%
GAAP EPS$0.58$0.64+10.3%

The discrepancy in valuation stems from the uncertainty of the legacy portfolio. Eliquis is currently facing Medicare price negotiations under the IRA. The negotiated price, which will take effect in 2026, is expected to be a 25% to 35% reduction from the current list price. Analysts have already baked this into their models, but the psychological weight of government intervention is keeping a lid on the stock price. The market is waiting for a clear sign that the ‘new’ BMY can outrun the ‘old’ BMY.

The Dividend Safety Margin

While the growth story is centered on Cobenfy, the floor for the stock is provided by its dividend. At $0.60 per share per quarter, the payout is well-covered by a payout ratio of approximately 38% of non-GAAP earnings. This provides a significant cushion. Even if revenue remains flat through the 2026 patent cliff, the company has the balance sheet strength to maintain its dividend and continue its $3 billion annual share buyback program. The risk-reward profile is skewed toward the upside for those who can tolerate the volatility of the clinical data coming in early 2026.

The critical milestone to watch is the January 2026 readout for the Phase 3 trial of Cobenfy in Alzheimer’s-related psychosis. This secondary indication would double the addressable market for the drug. If the data is positive, the current $53 share price will be viewed as a generational entry point. If it fails, the company will be forced to rely solely on the schizophrenia market to bridge its multi-billion dollar revenue gap. Watch the 10-year Treasury yield. If rates continue to soften, high-yielding pharma stocks like BMY will catch a bid as income seekers rotate out of money market funds and back into defensive equities with 4% yields.
