See Why Texas Instruments (TXN) Might Offer a Margin of Safety

Many investors turn to Benjamin Graham's so-called “Graham number” to calculate the fair price of a stock. The Graham number is √(22.5 * earnings per share * book value per share), which for Texas Instruments gives us a fair price of $48.25. In comparison, the stock’s market price is $168.24 per share. Therefore, Texas Instruments’s market price exceeds the upper bound that a prudent investor would pay for its shares by 248.7%.

Since the formula relies on Graham's assumptions about healthy price to book ratios, it doesn't accurately capture the value of modern technology companies, which are light on assets compared to the companies that Graham was analyzing in the mid twentieth century.

Furthermore, the Graham number is often used in isolation, but in fact it is only one part of a check list for choosing defensive stocks that he laid out in Chapter 14 of The Intelligent Investor. The analysis requires us to look at the following fundamentals of Texas Instruments:

Sales Revenue Should Be No Less Than $500 million

For Texas Instruments, average sales revenue over the last 3 years has been $15,729,333,333, so in the context of the Graham analysis the stock has impressive sales revenue. Originally the threshold was $100 million, but since the book was published in the 1970s it's necessary to adjust the figure for inflation.

Current Assets Should Be at Least Twice Current Liabilities

We calculate Texas Instruments's current ratio by dividing its total current assets of $13,685,000,000 by its total current liabilities of $2,569,000,000. Current assets refer to company assets that can be transferred into cash within one year, such as accounts receivable, inventory, and liquid financial instruments. Current liabilities, on the other hand, refer to those that will come due within one year. In Texas Instruments’s case, current assets outweigh current liabilities by a factor of 5.3.

The Company’s Long-term Debt Should Not Exceed its Net Current Assets

This means that its ratio of debt to net current assets should be 1 or less. Since Texas Instruments’s debt ratio is 0.7, the company has healthy debt levels. We calculate Texas Instruments’s debt to net current assets ratio by dividing its total long term of debt of $7,241,000,000 by its current assets minus total current liabilities.

The Stock Should Have a Positive Level of Retained Earnings Over Several Years

Texas Instruments had positive retained earnings from 2008 to 2021, during which time they averaged $42,622,666,667. Retained earnings are the sum of the current and previous reporting periods' net asset amounts, minus all dividend payments. It's a similar metric to free cash flow, with the difference that retained earnings are accounted for on an accrual basis.

There Should Be a Record of Uninterrupted Dividend Payments Over the Last 20 Years

Shareholders of Texas Instruments have received regular dividends since 2007. The company has returned an average dividend yield of 2.5% over the last five years.

A Minimum Increase of at Least One-third in Earnings per Share (EPS) Over the Past 10 Years

To determine Texas Instruments's EPS growth over time, we will average out its EPS for 2007, 2008, and 2009, which were $1.83, $1.44, and $1.15 respectively. This gives us an average of $1.47 for the period of 2007 to 2009. Next, we compare this value with the years 2019, 2020, and 2021, which were $1.12, $5.97, and $8.26, for an average of $5.12. Now we see that Texas Instruments's EPS growth was 248.3% during this period, which satisfies Ben Graham's requirement.

It may be trading far above its fair value, but Texas Instruments meets most of Benjamin Graham's criteria for a quality stock because it has:

  • impressive sales revenue
  • an excellent current ratio
  • healthy debt levels
  • positive retained earnings from 2008 to 2021
  • a solid record of dividends
  • EPS growth in excess of Graham's requirements
