Nvidia added $150 billion to its share buyback program on Monday, an increase the firm says is the largest in history. The chipmaker now plans to buy back $235 billion worth of stock through January 2028.
But what does it actually mean for an investor when a company buys back its own stock?
Companies typically buy back shares when they have excess cash, often purchasing their own stock on the open market. Nvidia CEO Jensen Huang told CNBC’s “Squawk Box” the company expects to generate “a lot of cash in the coming years” and wants to return some of it to shareholders.
Indeed, buybacks, like dividends, are viewed as a way companies can give back to those who invest in their stock. Unlike a dividend, which comes directly to shareholders in the form of cash, a buyback reduces the number of shares in circulation, leaving existing shareholders with a slightly larger piece of the company.
Nvidia’s announcement comes as share buybacks remain near record levels. But whether a buyback announcement is good news for investors isn’t always straightforward.
“A buyback is a receipt, not a reason to buy,” says Aaron Gaines, a certified financial planner with Gaines Capital Management in Georgia. A buyback announcement only tells you that management intends to spend the company’s cash on its own stock, not “whether they got a good deal.”
How stock buybacks work
Companies can use excess cash in a number of ways, including paying down debt, investing in new projects or expanding the business.
Fast-growing companies may be more inclined to reinvest that money to fuel further growth. More mature, cash-rich companies may instead choose to return some of that money to shareholders through dividends or stock buybacks.
A dividend pays shareholders cash based on the number of shares they own. When a company declares a dividend, it also announces when eligible shareholders will receive the payment. Investors can take that payment as cash income or use it to buy more shares of the stock. In a taxable account, dividend payments are generally taxable income.
With a buyback, the commitment to return cash to shareholders is less firm. The company authorizes the purchase of its own shares, but it doesn’t necessarily have to follow through on the full amount.
When the company does repurchase shares, it reduces the number of shares in circulation, leaving investors who hold onto their stock owning a slightly larger piece of the company.
It can also boost earnings per share, or EPS, because the company’s earnings are divided among fewer shares. That can make a stock appear more attractive to investors, even when the company’s overall earnings haven’t changed.
“It’s inherently increasing the earnings per share, although synthetically,” says Rob Leiphart, a certified financial planner and vice president of financial planning at RB Capital Management.
Buybacks and dividends also differ in how much they commit a company to returning cash in the future. Once a company begins paying a regular dividend, investors tend to expect those payments to continue — and potentially increase over time. Investors can react negatively when a company cuts its dividend, Leiphart says.
“The same can’t really be said about a buyback,” he says.
What should investors make of a stock buyback?
A buyback can tell investors that a company has cash it wants to spend on its own shares and may signal that management believes the stock is undervalued. But that alone doesn’t say whether the company is a good investment.
Instead, investors can look at measures such as free cash flow and revenue growth, as well as the company’s leadership and how its stock has performed relative to its peers, Leiphart says.
When it comes to the buyback itself, the company’s balance sheet matters. A heavy debt load could be a red flag, particularly if the company is borrowing money to repurchase shares, Leiphart says.
The price the company pays for its shares matters, too. Buying back undervalued shares can be an effective use of cash, while overpaying for them can destroy value. One way investors can gauge a stock’s valuation is by comparing its price-to-earnings ratio with those of similar companies, according to Fidelity.
“A buyback is only a good deal if the company is buying its own stock at a good price,” says Mark Stancato, a certified financial planner with VIP Wealth Advisors in Georgia.
There’s also the question of what else the company could do with the money. Leiphart points to research and development and hiring as potential alternatives to buying back stock.
And the amount a company spends on buybacks doesn’t necessarily translate into an equivalent reduction in its share count. Companies may also issue new shares as employee compensation, meaning some repurchases simply offset that dilution, says Leiphart.
Assessing a company’s financial health and valuation can be complicated, though, which is where a financial advisor can help. Even for investment professionals, though, a buyback is just one factor to consider when deciding whether a company is a good investment.
“I might mention it, but it’s not sort of an ingredient by which I’m picking a stock or selecting something for a client’s portfolio,” says Leiphart.
