I know someone close to me who has been offered employee stock options (which they are supposed to buy later at a fixed price, potentially, when/if the business goes to IPO or something) and they asked for my advice.

I asked what is the total number of shares as I never invested in a business without understanding how much of it I’m buying.

However, the company refused to share this information on the basis that it is “confidential”.

It feels very strange since they have been bragging about how many millions they received in funding.

Do you consider for this to be a red flag?

  • Are the options being offered as a perq? Does the person actually work their yet? Or are these being offered for purchase? Commented May 17, 2021 at 18:16

    Is it possible that you are confusing the strike price of the option as a 'buy' price? They are not the same thing.

  • Need to specify country. I believe in the United States, the number of shares of a corporation needs to be specified by its charter (and amendments), which is publicly filed with the state government authority in charge of companies.

    @Fabio this is confusing. You typically don't "buy" stock options: they are granted by the company as a part of your compensation. Once they are vested you can choose the "exercise" them, i.e. buy actual stock at the strike price of the option. Before the exercise the employee doesn't pay for anything.

  • @Hilmar, yes, your way of describing is more accurate. And this is the problem, why would my friend stay in the company for several more years if they don't know what a share is going to be (meaning, % of the business)? Commented May 18, 2021 at 17:28

Because they don't want other people to know. There's no incentive for the company to share this information with you or anybody else. Why would they want your friend to know how much (or little) of the company your they are getting? They also don't want this information getting into the wild for the world to know.

But it DOES matter, and your friend should press for this. However, unless they are a particularly desirable or high-level candidate, they are unlikely to be successful.

Your friend might still choose to join the company even if they don't have all the information, but it's a bigger gamble and they need to know that they might not really have that much value in the options and consider the offer accordingly.

I've joined companies without knowing what fraction of the company my options represented and not regretted it. It is what it is.

Also, they should be very clear what the vesting schedule and triggers are. If they leave after 18 months, while the company is still private, do they keep any of the options? VERY important question! It is trendy these days (for tax reasons) for vesting to require both time AND a "liquidity event" (going public, getting acquired, etc). So your friend can get trapped where they have $1M in unvested options that they don't want to leave behind ("golden handcuffs"), but those options may NEVER vest.


You seem not to understand how stock option work, which makes it difficult to answer your question.

Here is quick overview:.

  1. Stock options granted to an employee as part of their compensation and/or hiring bonus.
  2. Stock options give the owner the right to buy stock in the future at a specific price, called "the strike price" which is typically the fair market value at time of grant
  3. Initially stock options are worthless: in order for them to create value the share price needs to go up.
  4. Stock options "vest" over time, i.e. you can only exercise after a waiting period (typically 4 years with partial vesting after one year).
  5. The employee doesn't have to pay anything until they choose to exercise any options
  6. Typically you don't exercise unless there is a way to actual sell the shares. That's easiest if the share are publicly traded, but there are other mechanisms as well.
  7. Exercising option and selling shares can have very complicated tax implications: it's strongly recommended that you discuss this with a financial advisor first. Some people in the US have been bankrupted by this!

why is the total number of shares a secret?

Because it doesn't matter. You are not getting "a percentage of the company" you are getting the right to buy shares for a certain price in the future.

In order to valuate the stock options you need to guestimate what the stock price in the future will be. For a non-public company the share price is typically set by the board of directors in regulars intervals, so you can track this and see where it goes. The total number of outstanding shares simply isn't relevant for the value of your options.

    This is the opposite of true. It matters greatly. They are paying you with options on a percentage of the company - an unknown percentage that depends on how many total shares are outstanding.

  • "For a non-public company the share price is typically set by the board of directors in regulars intervals, so you can track this and see where it goes." While this is possible and I have seen it myself, I would not say it is common - I would say it is more common that the only way to sell shares in a private company is to find a buyer yourself, perhaps even with limitations on who is allowed to buy shares as dictated by the incorporating documents. The key question to OP's friend is - *is there a method of actually cashing these shares out, and do you know how to estimate that price now?" Commented May 20, 2021 at 15:09
  • "to valuate the stock options you need to guestimate what the stock price in the future will be." Don't you also need to know the strike price, which you would subtract from the future stock price?
