Understanding Stock Options in Private Companies

Quick answer

• Stock options in private companies grant you the right to buy company stock at a predetermined price (the strike price) within a specific timeframe.
• Vesting schedules determine when you can exercise your options, often spread over several years.
• Exercising options means buying the stock; you then own shares that may increase in value.
• The primary benefit is potential financial gain if the company’s valuation increases significantly.
• Key risks include the possibility of the stock value not rising above the strike price, or the company never having a liquidity event (like an IPO or acquisition).
• Understanding tax implications, especially for Incentive Stock Options (ISOs) versus Non-Qualified Stock Options (NSOs), is crucial.

Who this is for

• Employees of startups and private companies who have been granted stock options as part of their compensation.
• Individuals looking to understand the potential financial upside and risks associated with their equity grants.
• Anyone curious about how private company equity can translate into personal wealth.

What to check first (before you act)

Your Grant Agreement and Company Policy

Review your official stock option grant document carefully. This is the contract outlining the specific terms of your options. Pay close attention to:

• Number of options granted: This is the total number of shares you have the right to purchase.
• Strike price (or exercise price): This is the fixed price per share at which you can buy the stock.
• Vesting schedule: This details when your options become exercisable. Common schedules include a cliff (e.g., no options vest for one year, then 25% vest) followed by monthly or quarterly vesting over several more years.
• Expiration date: This is the absolute deadline by which you must exercise your vested options, or they will be forfeited.

Your Goals and Timeline

Consider what you hope to achieve with these options. Are you looking for a significant financial windfall in the long term, or is this more of a supplemental benefit? Your personal financial goals and risk tolerance will influence how you approach managing your options. Think about how long you anticipate staying with the company and when you might need access to funds.

Company Valuation and Potential Liquidity Events

Understand the company’s current valuation and its prospects for growth. While private companies don’t have publicly traded stock, their internal valuation can give you an idea of the potential value of your options. Research the company’s funding rounds and any indications of future plans, such as an Initial Public Offering (IPO) or acquisition (often referred to as a “liquidity event”). Without such an event, your options may remain illiquid.

Your Personal Financial Situation

Assess your current financial health. Do you have an adequate emergency fund? Can you afford to pay the exercise price for your options, plus any potential taxes, without jeopardizing your immediate financial stability? Exercising options requires capital, and you need to ensure this doesn’t strain your existing budget.

Step-by-step (how do options work in a private company)

1. Receive Your Grant Notification:

• What to do: You’ll be informed that you’ve been granted stock options, usually in writing. This document will contain initial details.
• What “good” looks like: Clear communication from your employer with access to your grant agreement.
• Common mistake: Assuming all options are immediately available or understanding the terms without reading the official documents.
• Avoid it by: Requesting and thoroughly reading your official stock option grant agreement.

2. Understand Your Vesting Schedule:

• What to do: Study the vesting schedule outlined in your grant agreement. This determines when you earn the right to exercise your options.
• What “good” looks like: A clear understanding of the timeline for when your options become exercisable.
• Common mistake: Not realizing that unvested options have no value to you yet.
• Avoid it by: Mapping out your vesting milestones on a calendar or spreadsheet.

3. Monitor Company Performance and Valuation:

• What to do: Stay informed about your company’s progress, growth, and any changes in its valuation.
• What “good” looks like: Being aware of the company’s trajectory and potential future value.
• Common mistake: Ignoring the company’s performance, assuming your options will automatically become valuable.
• Avoid it by: Participating in company updates, reading internal communications, and understanding industry trends.

4. Exercise Vested Options:

• What to do: Once options have vested according to your schedule, you have the right to purchase them at the strike price. You initiate this process through your employer.
• What “good” looks like: Successfully executing the purchase of vested shares.
• Common mistake: Missing the window to exercise vested options before they expire.
• Avoid it by: Setting reminders well before the expiration date.

5. Pay the Exercise Price and Any Applicable Taxes:

• What to do: You’ll need to pay the total cost to acquire the shares (number of vested options multiplied by the strike price) and potentially taxes.
• What “good” looks like: Having the necessary funds readily available to cover the exercise cost and immediate tax liabilities.
• Common mistake: Not having enough cash on hand to exercise, or being surprised by immediate tax obligations.
• Avoid it by: Budgeting for exercise costs and consulting with a tax advisor about potential tax implications beforehand.

6. Hold the Acquired Shares:

• What to do: After exercising, you become a shareholder. You now own the actual stock.
• What “good” looks like: Possessing shares in the company with the potential for future appreciation.
• Common mistake: Not understanding the difference between having the right to buy stock (options) and actually owning the stock.
• Avoid it by: Confirming that the transaction is complete and you have received proof of ownership.

7. Wait for a Liquidity Event:

• What to do: For private company stock, you typically need a liquidity event (IPO, acquisition) to sell your shares and realize their value.
• What “good” looks like: The company achieving a milestone that allows shareholders to sell their stock.
• Common mistake: Expecting to be able to sell your private company shares on demand like public stock.
• Avoid it by: Understanding that liquidity is not guaranteed and can take many years, if it happens at all.

8. Sell Shares During a Liquidity Event:

• What to do: When a liquidity event occurs, you’ll have the opportunity to sell your shares, usually at the prevailing market value at that time.
• What “good” looks like: Successfully selling your shares and receiving cash based on the company’s valuation.
• Common mistake: Not being prepared for the tax implications of selling shares, which can be significant.
• Avoid it by: Consulting with a tax professional well in advance of a planned liquidity event.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not reading the grant agreement	Missed deadlines, forfeiture of options, misunderstanding terms	Read every word of your grant agreement and any accompanying documentation.
Forgetting to track vesting	Exercising options too late, losing the right to buy	Create a calendar or spreadsheet to track vesting dates and deadlines.
Assuming options will always be valuable	Exercising worthless options, losing money on exercise costs and taxes	Regularly assess company performance and market conditions. Don’t exercise if the strike price is higher than the stock’s value.
Not having cash for exercise/taxes	Inability to exercise vested options, forfeiture, missing out on potential gains	Save diligently for exercise costs and potential tax liabilities.
Exercising too early (especially ISOs)	Triggering Alternative Minimum Tax (AMT) or losing favorable tax treatment	Consult a tax advisor before exercising to understand the tax implications.
Holding private stock indefinitely	Missing liquidity events, potential for shares to become worthless if company fails	Stay informed about company plans and be ready to act during liquidity events.
Not understanding post-termination exercise rules	Forfeiting vested options if you leave the company before exercising them	Be aware of the specific rules in your grant agreement regarding exercising options after leaving employment.
Over-concentrating wealth in one stock	Significant financial risk if the company underperforms or fails	Diversify your overall financial portfolio; don’t let company stock become your sole source of wealth.
Ignoring the expiration date	Complete forfeiture of all vested, unexercised options	Mark expiration dates clearly on your calendar and set multiple reminders.
Assuming private stock is easily sellable	Inability to access funds when needed, missed opportunities, unexpected liquidity issues	Understand that private stock is illiquid and requires a specific event to be sold.

Decision rules (simple if/then)

• If your options are vested and the company’s valuation is significantly higher than your strike price, then consider exercising to capture potential gains because holding them longer could increase their value, but also carries risk.
• If you are considering exercising Incentive Stock Options (ISOs), then consult a tax advisor before doing so because of potential Alternative Minimum Tax (AMT) implications.
• If you are nearing the expiration date of your options, then you must exercise any vested options you wish to keep, because they will be forfeited otherwise.
• If you are leaving the company, then immediately review your grant agreement for post-termination exercise windows because you may have a limited time to exercise vested options.
• If you don’t have sufficient cash to cover the exercise price and potential taxes, then you may need to forgo exercising some or all of your vested options because you cannot acquire shares you cannot afford.
• If the company’s valuation is below your strike price, then it generally does not make financial sense to exercise your options because you would be paying more for the stock than it is currently worth.
• If you are unsure about the tax treatment of your specific option type (ISO vs. NSO), then seek professional tax advice because different rules apply and can significantly impact your net proceeds.
• If the company is approaching a liquidity event (IPO or acquisition), then begin planning for the tax consequences of selling your shares because capital gains taxes will likely apply.
• If you have a large number of vested options, then consider exercising them incrementally over time if possible, to spread out the financial outlay and tax burden.
• If the company’s future prospects seem uncertain, then it may be prudent to exercise only a portion of your vested options, or none at all, to mitigate risk.

FAQ

What is the difference between Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs)?

ISOs offer potential tax advantages, where you might not pay ordinary income tax upon exercise, but could owe AMT. NSOs are taxed as ordinary income on the “spread” (difference between strike price and market value) at exercise.

When can I exercise my stock options?

You can typically only exercise options that have “vested” according to your grant agreement’s schedule. Unvested options are not yet yours to buy.

What is a “strike price” or “exercise price”?

This is the fixed price per share you agree to pay when you exercise your option to buy the company’s stock. It’s set when the options are granted.

What happens if I leave the company?

Most grant agreements have a “post-termination exercise period,” often 90 days, during which you must exercise any vested options. If you don’t, they are usually forfeited.

How do I know if my options are worth exercising?

You should compare the current market value of the company’s stock to your strike price. If the market value is higher, exercising could be profitable, assuming a future sale.

What is a “liquidity event”?

This is a significant event that allows shareholders to sell their shares and convert their equity into cash. The most common are an Initial Public Offering (IPO) or an acquisition of the company.

Can I sell my private company stock anytime?

Generally, no. Private company stock is illiquid, meaning it’s not easily bought or sold on a public market. You typically must wait for a liquidity event.

What is “vesting” and why is it important?

Vesting is the process by which you earn the right to exercise your stock options over time. It’s a way for companies to incentivize employees to stay with the company long-term.
