Recent Financial Performance: A Deep Dive into Fiscal Year 2024#

Amgen's financial performance in fiscal year 2024 presented a mixed picture, characterized by strong top-line growth alongside a notable contraction in profitability. The company reported revenue of $33.42 billion for FY 2024, marking a substantial +18.57% increase from the $28.19 billion reported in FY 2023 [Monexa AI]. This impressive revenue growth signals successful market penetration for existing products and initial contributions from recent strategic initiatives, including the acquisition of Horizon Therapeutics.

However, this revenue expansion was accompanied by a significant downturn in net income. Amgen's net income for FY 2024 stood at $4.09 billion, a sharp -39.11% decrease from the $6.72 billion recorded in FY 2023 [Monexa AI]. This decline is primarily attributable to increased operating expenses, particularly a substantial rise in the cost of revenue and heightened research and development (R&D) expenditures. The cost of revenue surged to $12.86 billion in FY 2024, up from $8.41 billion in FY 2023, reflecting changes in product mix and potentially integration costs from the Horizon acquisition [Monexa AI].

Profitability and Expense Dynamics#

The gross profit margin experienced a noticeable compression, falling to 61.53% in FY 2024 from 70.15% in FY 2023 [Monexa AI]. This reduction underscores the impact of higher cost of goods sold relative to revenue growth. Operating income also saw a decline, settling at $7.26 billion in FY 2024, an -8.00% drop from $7.90 billion in the prior year, bringing the operating income ratio down to 21.71% from 28.01% [Monexa AI].

Research and Development (R&D) expenses increased significantly by +24.69% to $5.96 billion in FY 2024, up from $4.78 billion in FY 2023 [Monexa AI]. This substantial investment reflects Amgen's commitment to advancing its pipeline, including pivotal clinical trials for drugs like Imdelltra and MariTide. Selling, General, and Administrative (SG&A) expenses also climbed to $7.10 billion in FY 2024, a +14.89% increase from $6.18 billion in FY 2023, indicating increased commercialization efforts and operational overhead [Monexa AI]. These elevated expenses, while necessary for future growth, weighed heavily on the company's short-term profitability.

Strategic Pipeline Catalysts: Driving Future Growth#

Amgen's strategic focus on its pipeline is a critical component of its long-term growth narrative, especially as it navigates the impending patent expirations of key products. The company's substantial R&D investments are now beginning to yield promising clinical results for novel therapies, which are poised to become significant revenue drivers.

Imdelltra (Tarlatamab): A New Horizon in Oncology#

Imdelltra (tarlatamab) is emerging as a cornerstone of Amgen's oncology portfolio, particularly in the challenging landscape of small cell lung cancer (SCLC). Recent data published in the New England Journal of Medicine in June 2025 underscored its efficacy, demonstrating a 40% reduction in mortality risk for SCLC patients in the second-line setting. This clinical profile positions Imdelltra favorably against established competitors such as AstraZeneca's Imfinzi and Pfizer's Bavencio, which have traditionally dominated this space. Analysts project Imdelltra's peak sales to potentially reach between $700 million and $1.1 billion, with an anticipated market share of 15-20% in the second-line SCLC segment [Monexa AI, citing analyst consensus]. This represents a crucial commercial opportunity for Amgen, diversifying its oncology footprint beyond its existing portfolio and strengthening its competitive stance in a high-need area.

MariTide: Amgen's Bold Entry into Metabolic Diseases#

Amgen's strategic foray into the lucrative metabolic disease sector with MariTide marks another significant growth avenue. Unveiled at the American Diabetes Association's sessions in June 2025, MariTide's Phase 2 data revealed compelling results, demonstrating significant weight loss and improvements in glycemic control American Diabetes Association Sessions - MariTide Data. This positions MariTide as a potential disruptor in the burgeoning $100 billion metabolic disease market, where it is set to compete with the highly successful GLP-1 agonists from industry behemoths like Novo Nordisk and Eli Lilly.

MariTide's innovative mechanism of action offers a differentiated approach, which could allow Amgen to capture a meaningful share of this rapidly expanding market. The strategic importance of MariTide cannot be overstated, as it represents Amgen's commitment to expanding into high-growth therapeutic areas beyond its traditional strengths in oncology and inflammation. Success here would provide a substantial new revenue stream and significantly enhance Amgen's long-term growth prospects.

Navigating Competitive and Litigation Headwinds#

While Amgen's pipeline shows immense promise, the company is simultaneously navigating significant competitive pressures and the financial repercussions of recent litigation. These factors introduce a degree of uncertainty that investors must consider when assessing the company's future trajectory.

The Impact of PCSK9 Litigation on Repatha#

Amgen recently faced a setback in its PCSK9 litigation concerning its cholesterol-lowering drug, Repatha. A court ruling in June 2025 challenged Amgen's patent protection against Regeneron, potentially eroding Repatha's market exclusivity Amgen's PCSK9 Litigation Outcome. This development has prompted analysts to predict a 5-10% reduction in Repatha's sales projections over the coming years [Monexa AI, citing analyst consensus].

This litigation outcome necessitates a strategic recalibration for Amgen in the highly competitive PCSK9 inhibitor space. The company may need to explore more aggressive pricing strategies or intensify its marketing efforts to defend its market share against increasing competition. The long-term financial ramifications will depend on Amgen's ability to adapt its commercial strategy and potentially pursue alternative legal avenues or settlement discussions.

Looming Patent Expirations and Pipeline Diversification#

The strategic effectiveness of Amgen's R&D investments is further underscored by the impending patent expirations of several key products, including Prolia and Enbrel. These blockbusters have historically contributed significantly to Amgen's revenue, and their loss of exclusivity will create revenue headwinds. This makes the success of mid-to-late-stage pipeline assets, such as those in bone health, cardiovascular diseases, and neuroscience, even more critical.

Amgen is also exploring potential expansions for existing assets like Tepezza, which could provide additional revenue streams. The company's ability to successfully commercialize these new products and indications will be crucial for offsetting revenue declines from off-patent drugs and sustaining its overall growth momentum. This strategic pivot towards a diversified pipeline is a proactive measure to mitigate patent cliff risks and ensure long-term revenue stability.

Financial Health, Capital Allocation, and Shareholder Returns#

Amgen's balance sheet reflects a company that has undergone significant capital structure changes, largely influenced by strategic acquisitions. As of FY 2024, Amgen reported total assets of $91.84 billion, a -5.46% decrease from $97.15 billion in FY 2023 [Monexa AI]. This contraction is primarily due to a reduction in goodwill and intangible assets, which declined to $46.34 billion in FY 2024 from $51.27 billion in FY 2023, likely reflecting post-acquisition accounting adjustments [Monexa AI].

Total liabilities stood at $85.96 billion in FY 2024, a -5.46% decrease from $90.92 billion in FY 2023 [Monexa AI]. Long-term debt remained substantial at $56.55 billion, though it saw a -11.45% reduction from $63.86 billion in FY 2023, indicating some debt repayment efforts [Monexa AI]. The company's total debt-to-equity ratio, based on FY 2024 balance sheet figures, was approximately 10.22x (calculated as $60.10B total debt / $5.88B total stockholders' equity), reflecting a highly leveraged capital structure, which is common in the pharmaceutical industry following large acquisitions. The TTM debt-to-equity ratio is 9.24x [Monexa AI].

Cash Flow and Liquidity#

Despite the decline in net income, Amgen demonstrated robust cash flow generation. Net cash provided by operating activities surged to $11.49 billion in FY 2024, a significant +35.64% increase from $8.47 billion in FY 2023 [Monexa AI]. This strong operating cash flow translated into healthy free cash flow of $10.39 billion, representing a substantial +41.24% increase from $7.36 billion in the prior year [Monexa AI]. This strong free cash flow generation provides Amgen with considerable flexibility for debt reduction, R&D investments, and shareholder returns.

The current ratio, a measure of short-term liquidity, decreased to approximately 1.26x in FY 2024 from 1.65x in FY 2023 [Monexa AI]. While still above 1.0x, this indicates a slight tightening of short-term liquidity, possibly due to increased current liabilities or strategic deployment of current assets. The TTM current ratio is 1.17x [Monexa AI]. Cash and cash equivalents increased to $11.97 billion in FY 2024, up +9.41% from $10.94 billion in FY 2023, providing a solid cash buffer [Monexa AI].

Shareholder Returns and Dividend Sustainability#

Amgen maintains a commitment to shareholder returns through its dividend program. The company's last declared dividend was $2.38 per share for the payment on June 6, 2025, following a declaration on March 4, 2025 [Monexa AI]. The trailing twelve months (TTM) dividend per share is $9.26, yielding a 3.2% dividend yield [Monexa AI].

The dividend payout ratio stands at 82.64% based on TTM earnings [Monexa AI]. While this payout ratio is relatively high, the strong free cash flow generation of $10.39 billion in FY 2024, significantly exceeding the $4.83 billion paid in dividends [Monexa AI], suggests that the dividend remains sustainable. The company also engaged in modest common stock repurchases of $200 million in FY 2024, a significant reduction from $6.36 billion in FY 2022, likely prioritizing debt reduction post-acquisition [Monexa AI]. Management's execution of capital allocation appears disciplined, balancing R&D investment, debt management, and shareholder returns.

Analyst Expectations and Future Trajectory#

Analyst sentiment surrounding Amgen's future trajectory is generally positive, underpinned by the anticipated success of its pipeline and ongoing operational efficiency improvements. The company has consistently exceeded earnings estimates, with its actual earnings results surpassing estimated earnings in the last four reported quarters. For instance, in May 2025, Amgen reported an actual EPS of $4.90 against an estimated $4.27 [Monexa AI].

Future earnings per share (EPS) estimates reflect a positive outlook, with analysts forecasting EPS to grow from an estimated $20.86 in FY 2025 to $24.01 in FY 2029 [Monexa AI]. Similarly, estimated revenue is projected to increase from $35.28 billion in FY 2025 to $38.44 billion in FY 2029 [Monexa AI]. These projections highlight the market's confidence in Amgen's ability to drive top-line growth through its new product launches and manage the impact of patent expirations.

Valuation metrics also suggest a potentially attractive entry point. Amgen's trailing P/E ratio is 26.35x [Monexa AI]. However, its forward P/E ratio is estimated at 13.78x for 2025, declining to 11.98x by 2029 [Monexa AI]. The enterprise value to EBITDA (EV/EBITDA) is 16.49x (TTM), with forward EV/EBITDA estimates showing a similar downward trend, from 12.17x in 2025 to 11.17x in 2029 [Monexa AI]. These forward multiples indicate that the market anticipates improved earnings and EBITDA generation in the coming years, potentially making the stock more attractive relative to its future earnings power.

Strategic Effectiveness and Investor Implications#

Amgen's current strategic initiatives, particularly its aggressive investment in the oncology and metabolic disease pipelines, appear well-aligned with changing market conditions and the need to diversify revenue streams ahead of patent expirations. The substantial increase in R&D spending in FY 2024, while impacting short-term net income, is a necessary investment for long-term growth. The success of Imdelltra and MariTide will be critical litmus tests for the effectiveness of this strategy.

Historically, Amgen has demonstrated a robust capability in bringing innovative therapies to market. For instance, the company's expansion into biosimilars in the mid-2010s showcased its ability to adapt to evolving market dynamics and competitive pressures. However, the recent PCSK9 litigation outcome for Repatha serves as a reminder of the inherent risks in the pharmaceutical industry, particularly concerning intellectual property. Management's response to this challenge, whether through pricing adjustments or increased marketing, will be a key indicator of its execution capabilities.

The strong operating and free cash flow generation provide Amgen with financial flexibility, enabling continued investment in its pipeline, managing its substantial debt load, and sustaining its dividend. The company's balance between short-term financial performance and long-term strategic investments, as evidenced by its capital allocation patterns, suggests a disciplined approach to growth.

What This Means for Investors#

For investors, Amgen presents a compelling narrative of innovation and strategic adaptation within the biotechnology sector. The company's focus on high-potential areas like oncology and metabolic diseases, coupled with its proven R&D capabilities, positions it for future revenue growth. The anticipated commercial success of Imdelltra and MariTide represents significant catalysts that could drive future stock performance.

However, the decline in net income in FY 2024 and the ongoing patent litigation for Repatha highlight the inherent risks and complexities. Investors should closely monitor the commercial ramp-up of new drugs, the company's debt reduction efforts, and its ability to navigate competitive landscapes and regulatory hurdles. The sustainability of its dividend, supported by strong free cash flow, adds an attractive component for income-focused investors. Amgen's ability to execute its strategic vision and translate pipeline successes into sustained profitability will be the ultimate determinant of its long-term investment appeal.
