Amgen Inc. is headquartered in United States and Bank of America Corporation operates from United States, and those different home markets shape how each company competes.

Amgen Inc.: A Japanese brewery kept Amgen alive. The upfront payment kept Amgen's laboratory lights on. Five years later, EPO became the first blockbuster drug in biotechnology history. The Kirin deal was not charity; it was a calculated exchange of geographic rights for survival capital. Without it, there might be no Amgen. The FTC sued to block the deal, arguing that Amgen could use its portfolio rebate structures to foreclose competing drugs from formularies. The companies won in court and closed the transaction. The companies won. The acquisition closed. It was the most expensive biotech deal of the year and among the largest in a decade, financed primarily with debt that raised Amgen's leverage ratio significantly. Thousand Oaks, California, 1980. In 1983, scientist Fu-Kuen Lin cloned the gene for erythropoietin, the hormone that signals bone marrow to produce red blood cells. Chemotherapy destroys bone marrow's ability to produce those cells, leaving cancer patients severely anemic and requiring frequent blood transfusions. A synthetic EPO could eliminate the need for transfusions. The FDA approved Epogen in 1989.

Bank of America Corporation: Amadeo Giannini opened for business the morning after the 1906 San Francisco earthquake from a plank laid across two barrels on the sidewalk, lending money from his personal safe to survivors who needed to rebuild. No other bank in San Francisco was open. That story — the Bank of Italy making loans while its competitors kept their vaults locked — is not just founding mythology. It established a customer philosophy that shaped Bank of America's strategy for the next 120 years: serve customers that large banks avoid. Bank of America Corporation is the second-largest bank in the United States by assets, with approximately $3.3 trillion on its balance sheet and $113.1 billion in revenue for FY2025. Headquartered in Charlotte, North Carolina — not San Francisco, where it was founded, because the 1998 merger of BankAmerica with NationsBank made the Charlotte-based acquiring entity the surviving legal entity — the company employs approximately 213,000 people and serves 68 million consumer and small business clients. CEO Brian Moynihan has run the company since 2010, implementing what he calls "responsible growth" — organic expansion without dramatic acquisitions, with emphasis on returning capital through dividends and buybacks rather than leveraging up for defining deals. The contrast with the 2008-2009 crisis acquisitions of Countrywide Financial and Merrill Lynch, which cost the company over $40 billion in combined write-downs and legal settlements, is deliberate and explicit. The digital banking platform, with over 58 million digital users and 46 million mobile users, processes billions of transactions annually and represents the largest self-service banking infrastructure in the country. Erica, the AI-powered virtual assistant, handles hundreds of millions of client interactions per year — a volume that would require several thousand additional human employees if served through call centers.

Amgen Inc. and Bank of America Corporation pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Amgen Inc. and Bank of America Corporation.

Amgen Inc. business model: This segment has lower margins than branded biologics but provides volume growth and demonstrates Amgen's commitment to lower-cost medicine access — a narrative that carries important political value during a period of intense congressional scrutiny of drug pricing. The problem is, Amgen's operating margins have typically run between 30% and 35% on a GAAP basis and higher on an adjusted basis, reflecting both the pricing power of its branded biologics and decades of operational refinement. Amgen's financial profile in fiscal year 2024 reflected both the far-reaching impact of the Horizon Therapeutics acquisition and the ongoing pressure from patent expirations and pricing pattern. Ten drugs were subject to the first round of negotiations for 2026 pricing, and Enbrel was among the drugs selected for the second cycle of negotiations targeting 2027. It added Tepezza for thyroid eye disease and Krystexxa for chronic refractory gout — rare disease assets with high per-patient pricing and limited competition.

Bank of America Corporation business model: The 68 million consumer and small business clients generate net interest income (the spread between what the bank pays depositors and what it earns lending that money out), plus interchange fees every time someone swipes a debit card. Thousands of financial advisors manage trillions in client balances, earning asset-based fees that compound as markets rise. Revenue comes from loan spreads, treasury fees, and investment banking fees for underwriting and M&A advisory. The bank earns more from her at every stage, and the switching cost compounds because moving one product means disrupting all of them. Revenue model: Bank of America earns net interest income from deposits and loans, fees from cards and payments, wealth-management fees, trading revenue, and investment-banking fees. Its investment bank generates higher fees. SoFi and Chime attract younger depositors with slick apps and no-fee structures, potentially intercepting the 28-year-old who would have opened a Bank of America checking account a decade ago. They just need to peel off the entry-level relationships that feed the higher-margin businesses upstream. The wealth management segment adds stability: fee-based revenue that grows with asset prices regardless of rate cycles. Yet the wealth management franchise converts commodity banking relationships into high-margin advisory fees. The mechanism is Preferred Rewards: a program that gives customers escalating benefits (better card rewards, rate discounts, fee waivers) based on their combined Bank of America and Merrill balances. The underrated factor here: digital engagement data helps the bank identify when a consumer client is ready for a wealth management referral, making the cross-sell pipeline more efficient without feeling pushy. A Merrill advisory relationship on a $500,000 portfolio generates $5,000+ in annual fees.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Amgen Inc. stack up against those of Bank of America Corporation.

Amgen Inc. competitive advantage: Before the first human clinical trial ever tested a biotech-derived protein drug, a small group of venture-backed scientists in a repurposed building in Newbury Park, California, were betting that living cells could be engineered to manufacture medicines at industrial scale — a concept so novel in 1980 that most of Wall Street barely had a vocabulary for it. What makes Amgen genuinely unusual among its peers is the combination of scientific credibility, manufacturing scale, and financial discipline it has maintained over four decades. That singular achievement — turning living cells into life-saving medicines at global scale — is the defining fact of Amgen's half-century existence. Amgen's business model is built on one of the most capital-intensive and intellectually demanding processes in American enterprise: translating fundamental biological discoveries into regulated, manufactured medicines that can be sold at scale. Amgen's manufacturing organization is among the most sophisticated in the biopharma industry, running validated large-scale biologic production at facilities in Thousand Oaks, California; West Greenwich, Rhode Island; Juncos, Puerto Rico; Breda, Netherlands; and Singapore. While Amgen's MariTide program represents a genuine opportunity, it enters a market where Eli Lilly's Zepbound (tirzepatide) and Novo Nordisk's Wegovy (semaglutide) have already established billion-dollar revenue bases and massive manufacturing advantages. Amgen's most durable competitive advantage is its manufacturing expertise in large-molecule biologics. Financially, Amgen's scale generates operating use that smaller biotech firms cannot match. EPO had been identified and partially characterized in previous research, but no one had successfully cloned the human EPO gene and produced recombinant EPO protein at meaningful scale. The recombinant DNA tools available in 1980 were primitive by modern standards, but they were sufficient to do something that had never been done: clone human genes, insert them into bacterial or mammalian cell cultures, and produce therapeutic proteins at commercial scale.

Bank of America Corporation competitive advantage: It's JPMorgan Chase — and the reason is simple: Jamie Dimon's bank does everything Bank of America does, does most of it better by measurable margins, and gets rewarded with a valuation premium that compounds the advantage. Competitive position: Bank of America's advantage is its large deposit base, Merrill wealth platform, corporate banking relationships, payments reach, and digital banking scale. The wealth management pipeline — converting checking account holders into advisory clients paying 1% annually on growing portfolios — is something JPMorgan hasn't replicated at the same scale. The moat exists. The question is whether the moat is widening or slowly silting up while JPMorgan's gets deeper. Bank of America's competitive advantage in consumer banking is increasingly technology-driven. This digital scale creates a compounding advantage — more users generate more behavioral data, enabling better personalization, which drives higher engagement and lower attrition, further increasing scale.

Future prospects matter as much as current results. The growth strategies below explain how Amgen Inc. and Bank of America Corporation each plan to expand from here.

Amgen Inc. growth strategy: But those same drugs carry price tags that have triggered congressional hearings, federal investigations, and public outrage. Amgen generates revenue through four primary mechanisms: branded biologic product sales in the United States, international product sales in Europe and other markets, licensing and royalty income from partnerships, and a rapidly expanding biosimilars portfolio. Key pipeline assets include MariTide (maridebart cafraglutide), an investigational obesity and diabetes drug that targets both GLP-1 receptor agonism and GIP receptor antagonism — a mechanism that could position Amgen to compete directly with Eli Lilly's tirzepatide and Novo Nordisk's semaglutide in the exploding weight loss drug market. The company has also advanced AMG 133 through Phase 2 trials with weight loss data that attracted significant investor attention in 2024 and 2025. The capital investment required to build and validate these facilities — routinely running into hundreds of millions or billions of dollars per site — creates a structural barrier that reinforces Amgen's competitive position. The company has invested in next-generation multiproduct manufacturing facilities that can be adapted to different biologic drug types with shorter reconfiguration times, improving capital efficiency. Capital allocation historically favored a combination of R&D reinvestment, dividend payments (the quarterly dividend reached $2.25 per share in 2024, yielding approximately 3%), and share repurchases. While the United States accounted for approximately 75% of product revenues in 2024, the company has been growing its ex-U.S. Presence, particularly in Europe where biosimilars face more receptive regulatory and market environments than in the U.S. Amgen's European commercial infrastructure, bolstered by its 2013 acquisition of deCODE Genetics in Iceland and longstanding partnerships across major EU markets, provides both revenue diversification and access to genomic research populations that inform drug discovery. Amgen Inc. was established at the dawn of the biotechnology era and has grown to become the archetype of what a successful independent biotech company can achieve. The company is organized into research and development divisions focused on oncology, cardiovascular and metabolic diseases, inflammation, bone health, rare diseases, and neuroscience. Amgen's competitive posture has evolved from a largely defensive stance in the early 2010s — when it was focused primarily on defending Enbrel and Neulasta from biosimilar competition — toward a more aggressive offensive strategy combining pipeline development, strategic acquisitions, and biosimilar market entry. The question of how much revenue Amgen can sustain through the mid-2020s patent cliff cycle while simultaneously growing new franchises defines the company's near-term financial trajectory. Amgen's growth strategy rests on four interdependent pillars that CEO Robert Bradway has consistently articulated to investors since 2020. Tepezza has significant underpenetrated market opportunity — the vast majority of thyroid eye disease patients remain undertreated despite Tepezza's strong clinical evidence — and Amgen has invested heavily in patient identification programs, specialist education, and payer coverage expansion since the acquisition closed. The third pillar is building the biosimilars business into a durable revenue contributor. Amgen has committed to launching biosimilar versions of multiple high-revenue biologics as they lose exclusivity through 2030, using its manufacturing capabilities to achieve cost structures that enable profitable competition at biosimilar price points. The fourth pillar is disciplined financial management — specifically debt reduction from the Horizon acquisition while preserving R&D investment and the dividend. Management has targeted returning to investment-grade credit metrics by 2027, which would restore full capital allocation flexibility including potential smaller bolt-on acquisitions in therapeutic categories where Amgen wants to build pipeline depth. The geographic growth opportunity in emerging markets, particularly China and Japan, where Amgen is building direct commercial presence, represents a longer-term revenue diversification vector. Amgen is attempting to offset this through volume growth in Repatha, Otezla, Tepezza, and biosimilars, while simultaneously advancing pipeline assets in oncology including tarlatamab (AMG 757), a bispecific T-cell engager targeting DLL3 for small cell lung cancer that received FDA accelerated approval in May 2024. Tarlatamab's launch performance will be an important indicator of Amgen's ability to build new oncology franchises beyond its historical reliance on supportive care drugs. Bowes, a partner at the venture firm U.S. Venture Partners, conceived the idea of building a biotech company from the ground up with experienced professional management at its helm rather than waiting for academics to evolve into businesspeople. Rathmann was not a molecular biologist, but he was a scientist with deep industry experience and an intuitive understanding of how to build research organizations. The company's initial scientific strategy was deliberately broad: it would pursue multiple research directions in protein biology simultaneously, betting that some would eventually yield commercial products without pre-committing to any single therapeutic hypothesis. Amgen moved its operations to a leased building in Newbury Park, California (later incorporated into Thousand Oaks), hiring scientists from Caltech, UCLA, and major pharmaceutical companies. This partnership, unconventional in the extreme — a biotechnology company licensing its core technology to a brewery — demonstrated the creative financial pragmatism that would characterize Amgen's management style for decades. The dual-product base gave the company the financial stability to invest in a research pipeline that would take two more decades to produce its next generation of commercially significant medicines.

Bank of America Corporation growth strategy: Bank of America is focused on responsible growth, deposit scale, digital engagement, wealth-management flows, global markets, payments, treasury services, and disciplined expense management.

A closer look at the financial trajectory of Amgen Inc. and Bank of America Corporation rounds out the comparison.

Amgen Inc.: Amgen reported FY2025 total revenues of $36.8 billion, up 10% year over year, and GAAP net income of $7.7 billion.
