What Does The Institutional Ownership Tell Us About ADTRAN Holdings?

Institutions typically measure themselves against a benchmark when reporting to their own investors, so they often become more enthusiastic about a stock once it's included in a major index. We would expect most companies to have some institutions on the register, especially if they are growing.

We can see that ADTRAN Holdings does have institutional investors; and they hold a good portion of the company's stock. This can indicate that the company has a certain degree of credibility in the investment community. However, it is best to be wary of relying on the supposed validation that comes with institutional investors. They too, get it wrong sometimes. When multiple institutions own a stock, there's always a risk that they are in a 'crowded trade'. When such a trade goes wrong, multiple parties may compete to sell stock fast. This risk is higher in a company without a history of growth. You can see ADTRAN Holdings' historic earnings and revenue below, but keep in mind there's always more to the story.

Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. Our data indicates that hedge funds own 5.3% of ADTRAN Holdings. That's interesting, because hedge funds can be quite active and activist. Many look for medium term catalysts that will drive the share price higher. The Vanguard Group, Inc. is currently the largest shareholder, with 10% of shares outstanding. In comparison, the second and third largest shareholders hold about 9.7% and 6.7% of the stock. In addition, we found that Thomas Stanton, the CEO has 1.2% of the shares allocated to their name.

After doing some more digging, we found that the top 11 have the combined ownership of 51% in the company, suggesting that no single shareholder has significant control over the company.

While it makes sense to study institutional ownership data for a company, it also makes sense to study analyst sentiments to know which way the wind is blowing. There are plenty of analysts covering the stock, so it might be worth seeing what they are forecasting, too.

Insider Ownership Of ADTRAN Holdings

The definition of an insider can differ slightly between different countries, but members of the board of directors always count. The company management answer to the board and the latter should represent the interests of shareholders. Notably, sometimes top-level managers are on the board themselves.

I generally consider insider ownership to be a good thing. However, on some occasions it makes it more difficult for other shareholders to hold the board accountable for decisions.

Shareholders would probably be interested to learn that insiders own shares in ADTRAN Holdings, Inc.. In their own names, insiders own US$14m worth of stock in the US$778m company. Some would say this shows alignment of interests between shareholders and the board. But it might be worth checking if those insiders have been selling.

General Public Ownership

The general public-- including retail investors -- own 13% stake in the company, and hence can't easily be ignored. While this size of ownership may not be enough to sway a policy decision in their favour, they can still make a collective impact on company policies.

Private Equity Ownership

Private equity firms hold a 6.7% stake in ADTRAN Holdings. This suggests they can be influential in key policy decisions. Some might like this, because private equity are sometimes activists who hold management accountable. But other times, private equity is selling out, having taking the company public.

It's always worth thinking about the different groups who own shares in a company. But to understand ADTRAN Holdings better, we need to consider many other factors.
