“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
Texas Instruments Inc. (NASD: TXN) offers a useful case study in long-term equity compounding. A hypothetical $10,000 investment in TXN made in September 2006 and held for 20 years, with dividends reinvested, would have grown to $129,100.75 by 09/02/2026. That equates to a total return of 1,190.75% and an annualized return of 13.64%.
The exercise highlights a point that is often obscured by short-term market volatility: for a high-quality dividend-paying semiconductor company, long holding periods can allow both operating performance and capital allocation discipline to meaningfully shape investor outcomes. In Texas Instruments’ case, the result came from a combination of share-price appreciation, cash dividends, and the incremental share accumulation produced by dividend reinvestment.

As the figures show, the hypothetical investment outcome was strong. Over the 20-year period ending 09/02/2026, a $10,000 initial investment grew to $129,100.75. [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
What Drove the Return
Texas Instruments’ long-term return was not solely a function of a higher stock price. The ending value reflects three distinct components:
- Share-price appreciation: the stock price rose from $32.03 to $254.80.
- Cash dividends: the company paid a cumulative $48.94 per share over the period examined.
- Dividend reinvestment: those dividends, when reinvested, increased the share count from 312.21 to 506.58 shares.
This distinction matters. Price return alone and total return can diverge materially over long periods, particularly for companies that regularly return capital to shareholders. In this case, reinvested dividends meaningfully amplified the ending position by purchasing additional shares over time, which then participated in future gains and future dividend payments.
How Dividend Reinvestment Changed the Outcome
For this calculation, dividends are assumed to be reinvested into additional shares using the closing price on the ex-dividend date. That assumption is central to the result. Without reinvestment, the investor would still have benefited from the dividend stream, but the compounding effect would have been lower because the share count would not have increased from 312.21 to 506.58.
Over long horizons, dividend reinvestment can be especially powerful when a company combines recurring free cash flow, a durable payout policy, and periods when the stock trades at varying valuations. Each dividend purchase adds small increments to ownership, and those increments accumulate over time.
Current Yield and Yield on Cost
Based on the most recent annualized dividend rate of $5.68 per share, TXN has a current yield of approximately 2.23% using the $254.80 ending share price in this example.
Another useful measure is yield on cost, which compares the current annualized dividend with the original purchase price. Using the same $5.68 annual dividend and the initial $32.03 purchase price, the yield on cost works out to 17.73%.
Yield on cost does not indicate what a new buyer would earn at today’s price, but it does illustrate how dividend growth can reshape the economics of a long-held position. For investors focused on income growth, that can be one of the clearest manifestations of long-term compounding.
Why Texas Instruments Is Often Studied as a Long-Term Dividend Compounder
Texas Instruments occupies a distinctive position within the semiconductor industry. The company has long emphasized analog and embedded processing chips, categories that tend to be tied to broad industrial and automotive demand and often carry longer product lives than leading-edge consumer processors. That business mix has historically supported strong cash generation and a shareholder-return model centered on dividends and buybacks.
That said, even strong long-term records in semiconductors rarely develop in a straight line. The sector is cyclical, capital intensive, and sensitive to swings in inventory, end-market demand, and broader economic conditions. The significance of TXN’s 20-year return is therefore not that volatility disappeared, but that the company produced a result in which long-run fundamentals ultimately outweighed multiple market cycles.
Key Takeaways
- A $10,000 investment in Texas Instruments in September 2006 grew to $129,100.75 by 09/02/2026, assuming dividends were reinvested.
- The position generated a 1,190.75% total return and a 13.64% annualized return.
- Dividends played a meaningful role, with $48.94 per share paid over the 20-year period examined.
- Reinvestment increased the share count from 312.21 to 506.58 shares, enhancing the compounding effect.
- At a current annualized dividend rate of $5.68, the implied current yield is about 2.23%, while yield on cost for the original 2006 purchase price is 17.73%.
