Insider Spends US$571k Buying More Shares In Butterfly Network

Butterfly Network, Inc. (NYSE:BFLY) shareholders (or potential shareholders) will be happy to see that the Independent Director, S. Phanstiel, recently bought a whopping US$571k worth of stock, at a price of US$3.08. That increased their holding by a full 65%, which arguably implies the sort of confidence required for a shy sweet-natured nerd to ask the most popular kid in the school to go out on a date.

Butterfly Network Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the CEO, President & Chairman of the Board, Joseph DeVivo, sold US$781k worth of shares at a price of US$2.44 per share. That means that even when the share price was below the current price of US$3.56, an insider wanted to cash in some shares. As a general rule we consider it to be discouraging when insiders are selling below the current price, because it suggests they were happy with a lower valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. It is worth noting that this sale was only 11% of Joseph DeVivo's holding.

Happily, we note that in the last year insiders paid US$653k for 235.26k shares. But insiders sold 670.78k shares worth US$1.5m. In total, Butterfly Network insiders sold more than they bought over the last year. The chart below shows insider transactions (by companies and individuals) over the last year. If you click on the chart, you can see all the individual transactions, including the share price, individual, and the date!

Does Butterfly Network Boast High Insider Ownership?

Looking at the total insider shareholdings in a company can help to inform your view of whether they are well aligned with common shareholders. We usually like to see fairly high levels of insider ownership. Butterfly Network insiders own 17% of the company, currently worth about US$155m based on the recent share price. This kind of significant ownership by insiders does generally increase the chance that the company is run in the interest of all shareholders.

So What Do The Butterfly Network Insider Transactions Indicate?

The recent insider purchase is heartening. On the other hand the transaction history, over the last year, isn't so positive. Overall, we'd prefer see a more sustained buying from directors, but with a significant insider holding and more recent purchases, Butterfly Network insiders are reasonably well aligned, and optimistic for the future. So these insider transactions can help us build a thesis about the stock, but it's also worthwhile knowing the risks facing this company. For instance, we've identified 3 warning signs for Butterfly Network (1 can't be ignored) you should be aware of.
