Research and Development (R&D)

Research and Development (R&D) is the engine room of innovation. It's the set of activities a company undertakes to discover new knowledge, which it then uses to create new products, services, or processes, or to improve existing ones. Think of it as a company's investment in its own future. For technology giants, it’s the quest for the next game-changing gadget; for pharmaceutical firms, it's the painstaking search for a life-saving drug. This spending is reported as an expense on the company’s income statement, directly reducing its reported profits for the period. While essential for long-term survival and growth in many industries, R&D is also a significant cost with no guarantee of a payoff. For an investor, understanding a company's approach to R&D is crucial for distinguishing between a business that is planting seeds for a future harvest and one that is just digging expensive holes.

R&D: An Expense or an Investment?

This question gets to the heart of a major quirk in accounting. According to standard accounting rules, R&D costs are treated as an expense in the year they are incurred. This means they are immediately subtracted from revenue, lowering a company's net income and making it appear less profitable. The logic is that the future benefits of R&D are too uncertain to be reliably recorded as an asset on the balance sheet. However, from a business and value investing perspective, R&D is clearly an investment. A company spends money today with the expectation of generating greater cash flows in the future. Legendary investor Ben Graham noted this discrepancy. By expensing R&D, a company's reported earnings can be significantly understated. A company investing heavily and successfully in its future might look less profitable on paper than a competitor that is coasting on past glories and starving its innovation pipeline. The savvy investor learns to look past the accounting treatment to see the economic reality.

How Value Investors Analyze R&D

A value investor doesn't just accept the R&D number at face value. Instead, they dig deeper to assess its quality and productivity. The goal is to figure out if the R&D spending is creating long-term value.

Looking Beyond the Numbers

The absolute amount spent on R&D is less important than its effectiveness. A company could spend billions with little to show for it, while a smaller, more focused competitor could generate breakthrough products with a modest budget. To assess this, you should investigate:

The R&D-to-Sales Ratio

A simple but powerful metric is the R&D-to-Sales ratio, calculated as: R&D Expense / Total Sales. This ratio helps you:

For context, a software or biotech company might have an R&D-to-Sales ratio of 15-25% or more, while a food manufacturer or a bank might be below 1%.

Capitalizing R&D for Valuation

For a more advanced analysis, some investors “capitalize” R&D to get a truer picture of a company's earning power. This involves adjusting the financial statements to treat R&D as a capital expenditure (CapEx) rather than an operating expense. The process, in simplified terms, is:

  1. 1. Adjust Operating Income: Add back the current year's R&D expense to the company's operating income.
  2. 2. Create an R&D Asset: Estimate the value of past R&D investments that still have a useful life (e.g., the last 5 years of spending). This becomes a new “asset” on the balance sheet.
  3. 3. Subtract Amortization: Instead of expensing the full R&D cost, you subtract an amortization charge (e.g., one-fifth of your new R&D asset).

This adjustment typically results in higher earnings and a larger asset base, which can dramatically change key valuation metrics like the Price-to-Earnings (P/E) ratio and Return on Invested Capital (ROIC), giving you a more economically realistic view of the business.
