Revenue Trajectory and Profitability Dynamics#
While revenue has shown a recent uptick, a deeper look at profitability reveals some shifts. Net income for 2024 stood at $4.41 billion, marking an +11.61% increase from $3.95 billion in 2023 (Monexa AI). However, it's crucial to note the significant decline from the $8.08 billion reported in 2021, reflecting a -18.25% 3-year CAGR for net income (Monexa AI). This decline can be partially attributed to increased operating expenses, which grew from $4.69 billion in 2021 to $8.24 billion in 2024 (Monexa AI), driven primarily by a substantial increase in research and development (R&D) expenses. R&D expenses surged from $2.91 billion in 2021 to $5.23 billion in 2024 (Monexa AI), a clear signal of REGN's commitment to pipeline investment.
Profitability ratios, while still robust, have compressed from their 2021 peaks. The net income ratio, for instance, decreased from 50.25% in 2021 to 31.07% in 2024 (Monexa AI). Similarly, the operating income ratio declined from 55.67% to 28.1% over the same period (Monexa AI). This trend is not necessarily a cause for alarm but rather a reflection of the significant reinvestment into the business, particularly in R&D, which now accounts for 36.23% of TTM revenue (Monexa AI). The company's gross profit ratio, however, has remained remarkably consistent, hovering around 86% over the past four years, highlighting efficient cost of goods management (Monexa AI).
Capital Allocation and Financial Strength#
REGN's balance sheet remains strong, providing ample liquidity and financial flexibility. As of December 31, 2024, total current assets stood at $18.66 billion against total current liabilities of $3.94 billion, yielding a healthy current ratio of 4.93x (Monexa AI). This indicates strong short-term liquidity. The company's total debt is manageable at $2.7 billion, with a debt-to-equity ratio of 0.09x (Monexa AI, signaling a conservative capital structure. Free Cash Flow (FCF) for 2024 was $3.66 billion, a slight decrease from $3.67 billion in 2023 (Monexa AI), but still substantial. The -0.08% year-over-year FCF growth and -17.51% 3-year FCF CAGR (Monexa AI) suggest that while the company generates significant cash, its growth in this metric has recently plateaued or slightly declined, likely due to increased capital expenditures and R&D. Regeneron also actively engages in share repurchases, with $3.63 billion allocated to common stock repurchases in 2024 (Monexa AI), demonstrating a commitment to returning value to shareholders.
Here's a snapshot of key financial metrics for REGN:

Beyond new approvals, Dupixent continues to strengthen its position in existing markets. Real-world data presented on June 24, 2025, for its use in chronic rhinosinusitis with nasal polyps (CRSwNP) confirmed sustained efficacy and improved patient-reported outcomes (Regeneron Clinical Trial Data, June 2025). This data provides crucial evidence of Dupixent's long-term benefits in a real-world setting, which is increasingly valued by healthcare providers and payers. In the competitive landscape of respiratory and inflammatory diseases, Dupixent has shown superiority in head-to-head comparisons against Xolair (omalizumab). Recent data in severe asthma demonstrated Dupixent's enhanced ability to reduce exacerbations and improve lung function, providing a distinct competitive advantage over existing therapies. This consistent clinical validation across multiple indications is key to Dupixent's sustained market dominance and its projected contribution of over $1 billion in additional annual sales by 2027 (Monexa AI).
Libtayo's Emerging Role in Oncology: Adjuvant CSCC Potential#
Libtayo (cemiplimab), REGN's immune checkpoint inhibitor, is carving out a significant niche in oncology, particularly in skin cancers. The drug has shown promising results in its Phase 3 clinical trial for the adjuvant treatment of high-risk cutaneous squamous cell carcinoma (CSCC). Updated data released in early June 2025 demonstrated a significant improvement in disease-free survival (DFS) compared to placebo, particularly in patients at high risk of recurrence (Regeneron Clinical Trial Data, June 2025). This is a critical development, as adjuvant therapy aims to prevent recurrence after initial treatment, addressing a significant unmet need in the CSCC patient population.
The adjuvant CSCC market represents a substantial commercial opportunity. With the positive trial outcomes, analysts project Libtayo could capture a considerable share of this market, estimated to be worth several hundred million dollars annually. Market penetration is anticipated to reach 40-50% within three years, contingent upon regulatory approvals and formulary access (Pharma Market Research, 2025). This growth trajectory underscores Libtayo's potential to become a key player in skin cancer immunotherapy, complementing REGN's existing portfolio and diversifying its revenue streams beyond immunology.
