Price return on share buyback

All,

I can't seem to wrap my head around the implications of share buybacks. It seems, from a numerical standpoint, that they are value destructive - but that can't be, right?

Let's say a company has excess cash of 100. It's enterprise value is calculated with a DCF to be 900. Because equity value equals enterprise value minus net debt, and excess cash is negative net debt, the equity value is 1,000.

Now, the company decides to buy back its own shares - to the value of 75 in total. You would think this increases the share price, as the value of the company is divided by fewer shares, but I'm not sure.

The enterprise value will continue to be 900, following from the DCF. However, excess cash falls to 25, so equity value falls to 925. There are less shares for the total equity value to be divided among, but there is also less equity value to begin with.

Is the 75 spent on the share buyback now just gone? There doesn't seem to be any distribution (as is the case with dividends, where share price goes down but shareholders receive some cash in return) - or at least nothing that clearly (traceably) appears.

Thanks in advance!

Based on the most helpful WSO content, share buybacks can indeed seem a bit counterintuitive at first glance, but they're not necessarily value destructive. Let's break down the scenario you've described to understand the dynamics at play:

  1. Initial Scenario: You've got a company with an enterprise value (EV) of 900, calculated through a DCF model. With excess cash of 100, the equity value (EqV) is 1,000 (since EqV = EV - net debt, and excess cash reduces net debt, making it negative in this calculation).

  2. Share Buyback Action: The company decides to use 75 of its excess cash to buy back shares. This action reduces the company's excess cash to 25, and assuming no other changes, the equity value would adjust to 925.

  3. Impact on Share Price: The key here is understanding that while the equity value decreases from 1,000 to 925 due to the reduction in excess cash, the number of shares outstanding also decreases because of the buyback. This reduction in shares outstanding can increase the value of each remaining share because the equity value of 925 is now spread over fewer shares.

  4. Value Transfer vs. Value Destruction: It's crucial to differentiate between value transfer and value destruction. In the case of dividends, value is transferred from the company to the shareholders in the form of cash payments. With share buybacks, the company is essentially investing in itself, reducing the number of shares outstanding, which can increase the value of the remaining shares if the market perceives the buyback as a positive signal (e.g., the company believes its shares are undervalued).

  5. Perception and Market Reaction: The market's perception of the share buyback can significantly influence the actual impact on share price. If investors believe the buyback is a sign of confidence from management in the company's future prospects, the share price may increase. However, if the buyback is seen as a lack of better investment opportunities or a way to artificially inflate share price metrics, the reaction could be less favorable.

  6. Long-term vs. Short-term: The immediate accounting impact shows a reduction in cash and equity value, but the long-term effect on share price will depend on how the buyback influences investor perception, the company's future earnings, and its ability to generate value.

In summary, the 75 spent on the share buyback isn't "just gone"; it's used to purchase and retire shares, potentially increasing the value of the remaining shares if the buyback is perceived positively and if it aligns with the company's strategic goals and financial health.
