The Short Version
A buyback (or share repurchase) is when a company purchases its own outstanding shares back from shareholders, either through a tender offer at a fixed premium or by buying gradually in the open market. Once repurchased, those shares are typically extinguished, reducing the total shares outstanding. Companies use buybacks to return surplus cash to shareholders, boost per-share metrics like EPS, or signal that management believes the stock is undervalued.
Explain It Like I'm 10
Imagine four friends jointly own a lemonade stand, each holding an equal slice. One friend decides they'd rather have cash than their slice, so the stand itself buys that friend's slice back and retires it. Now there are only three slices left, and the stand's same total profit gets divided three ways instead of four — meaning each remaining friend's slice is now worth more of the profit than before, even though the stand's actual business didn't grow at all.
Step-by-Step Example
- 1 A company has 100,000,000 shares outstanding and $100,000,000 in net income — EPS = $1.00.
- 2 It buys back and retires 10,000,000 shares using surplus cash.
- 3 Shares outstanding fall to 90,000,000, while net income (assuming it's unchanged) stays at $100,000,000.
- 4 New EPS = $100,000,000 ÷ 90,000,000 ≈ $1.11 — a higher EPS purely from fewer shares, with no actual improvement in the underlying business.
- 5 This is why EPS growth driven mainly by buybacks is worth distinguishing from EPS growth driven by genuine profit growth.
Quick Recap
- ✓ Tender offer buyback: the company offers to buy a fixed quantity of shares at a set (usually premium) price; shareholders can choose to participate proportionally.
- ✓ Open-market buyback: the company buys shares gradually on the exchange over time, like any other market participant.
- ✓ Reducing shares outstanding mechanically raises EPS and can raise ratios like ROE, even with no change in actual profit.
- ✓ Buybacks are typically funded from free reserves or securities premium and are capped/regulated by securities law (e.g., as a percentage of paid-up capital).
