Overall, I think Snap (NYSE:SNAP) will much more closely resemble Twitter (NYSE:TWTR) than Facebook (NASDAQ:FB), at least on most of the pertinent financial and operating metrics that investors evaluate. There is, however, one notable way that Snap is more like Facebook: voting.

There's been an annoying trend that's developed over the past two decades, most often found in Silicon Valley tech start-ups. In an effort to retain voting control, many start-ups establish dual share classes that preserve voting power for founders. The most prominent early example is a certain search giant, but there is no shortage of others. Expectedly, Snap similarly adopted multiple share classes for precisely this reason -- just like Facebook.

Who's the boss?

Any prospective investors considering buying shares of Snap once it goes public should accept that they will have quite literally no say in how the company is run or any other pertinent decisions that are typically put to shareholder votes. Snap has three share classes, and the Class A shares that will be sold to the public get exactly zero votes.

Share Class

Votes

Description

Class A

0

Being sold to public.

Class B

1

Convertible to Class A. Held mostly by early private investors, venture capitalists, and employees. Also used as currency for acquisitions.

Class C

10

Convertible to Class B. Held only by co-founders Evan Spiegel and Robert Murphy.

Since any Class B or Class C shares that are sold or transferred automatically convert to Class A (further concentrating voting power), public investors must have absolute faith in Spiegel and Murphy.

The same is true of Facebook, where Mark Zuckerberg rules with an iron fist thanks to his own supervoting shares. When Facebook when public in 2012, it had just two share classes, Class A and Class B. Class A shares were entitled to one vote, while Class B shares were entitled to 10. But last year Facebook created a third, non-voting Class C to further preserve his Zuckness's absolute authority even as he committed to donate 99% of his shares for philanthropic purposes. The date for the stock split has not been set yet. Public Facebook investors technically get a vote, but it's mostly an illusion of influence since Zuck Dawg personally controls 60% of all voting power, according to the company's 2016 proxy statement.

In contrast, Twitter took the high ground with corporate governance and did not go with a dual-class structure. Twitter has a single share class, and each share gets one vote. Nice and simple. All insiders collectively hold a modest 11% of voting power -- so investors' votes actually matter.
