Analysis of the Impact of High Debt Ratio on R&D Investment of Pharmaceutical Enterprises

As a typical capital-intensive and technology-intensive industry, R&D investment is the core element for pharmaceutical enterprises to maintain long-term competitiveness. High debt ratio has far-reaching multi-dimensional impacts on R&D investment of pharmaceutical enterprises, which is particularly worthy of attention in the current capital market environment.

Based on the general laws of the pharmaceutical industry and the general financial behavior patterns of high-debt enterprises, the impact of high debt ratio on R&D investment is mainly reflected in the following aspects [1][2].

The primary problem faced by enterprises with high debt ratios is the continuous consumption of cash flow by interest expenses. Taking large pharmaceutical enterprises as an example, when the debt level is high, interest expenses will significantly occupy operating cash flow, leading to a substantial reduction in free funds available for R&D activities [3]. This cash flow squeeze effect forces enterprise management to make difficult choices between debt repayment and R&D investment.

High debt is usually accompanied by a tight debt maturity structure, and enterprises need to continuously refinance to repay maturing debts. This refinancing pressure makes enterprises face uncertainty when formulating long-term R&D plans, and may be forced to postpone or reduce R&D projects [4].

Financial pressure directly leads to enterprises cutting R&D budgets:

• Decline in R&D expense ratio
  : High-debt enterprises tend to reduce the proportion of R&D expenditure to operating income
• Adjustment of project priorities
  : Only retain high-certainty, short-cycle R&D projects
• Staff streamlining
  : Reduce the size of R&D teams, affecting innovation capabilities and project execution efficiency

To maintain R&D activities under limited resources, enterprises may adopt the following strategies:

• Prioritize late-stage clinical projects and reduce early R&D investment
• Increase the proportion of external cooperative R&D to reduce independent R&D risks
• Focus on core therapeutic areas and reduce pipeline breadth

Continuous reduction in R&D investment will lead to a decline in enterprises’ core competitiveness:

• Insufficient pipeline reserves
  : Decline in the number and quality of products under development
• Weakening of patent barriers
  : Lack of patent protection for future product launches
• Loss of market share
  : Slowdown in the launch rhythm of innovative drugs

The valuation of high-debt pharmaceutical enterprises in the capital market will be affected:

• Decline in R&D capabilities leads to lower future growth expectations
• Rise in debt risk premium pushes up financing costs
• P/E ratio multiples may come under pressure

Taking international pharmaceutical giants as examples, enterprises such as Merck & Co. and Pfizer can maintain strong R&D investment when their financial conditions are sound. Merck’s current debt risk rating is “moderate_risk”, with a conservative financial attitude, and its free cash flow in 2024 reached 18.096 billion US dollars, providing a solid foundation for sustained R&D investment [5]. In contrast, enterprises with greater financial pressure face the dilemma of restricted R&D investment.

For high-debt pharmaceutical enterprises, the following measures are recommended to mitigate the negative impact on R&D investment:

1. Optimize capital structure
   : Reduce debt ratio through equity financing
2. R&D outsourcing cooperation
   : Cooperate with CRO enterprises to share R&D risks and costs
3. Pipeline priority management
   : Focus on high-value pipelines to improve R&D efficiency
4. Apply for government subsidies
   : Actively seek government support funds related to R&D

The impact of high debt ratio on R&D investment of pharmaceutical enterprises is multi-level and far-reaching. In the short term, it directly squeezes the funds available for R&D; in the long term, it weakens the enterprise’s innovation capabilities and competitive advantages. Therefore, pharmaceutical enterprises should seek a balance between expansion and financial stability, ensure the sustainability and effectiveness of R&D investment, and maintain long-term competitiveness.
