Basics of Employee Stock Ownership: Liquidity, Vesting, and Equity Types

Stock ownership is a powerful tool for aligning incentives between a company and its workforce, advisors, and board members. And if you’re an employee, your salary and bonus may not even be the main component of your compensation.

Equity ownership allows everyone to share in the success of the business and can serve as both a wealth-building mechanism and a retention strategy. However, the nuances of liquidity, vesting schedules, and different types of equity compensation play a crucial role in how employees and other stakeholders can access and benefit from their equity.

Liquidity: Public vs. Private Companies

One of the most significant considerations in employee stock ownership is liquidity—how easily employees can convert their shares into cash.

Public Companies: If a company is publicly traded, employees can generally sell their vested shares on the open market. Liquidity is relatively high, allowing employees to cash out when they choose (subject to potential lock-up periods after IPOs or trading restrictions around earnings announcements). But the downside of liquidity is that it can come with significant and unpredictable stock price fluctuations, directly impacting the value of holdings.

Private Companies: If the company is privately held, liquidity is far more limited. Employees typically need an exit event (such as an acquisition or IPO) to sell their shares. Some private companies offer tender offers or secondary sales, where employees can sell shares back to investors or the company itself. Otherwise, employees must wait until their shares become marketable. As a result, the value of privately held stock is far more speculative and uncertain compared to the value of a publicly traded stock. And the earlier the funding stage of the company – the more speculative and uncertain the value of its stock.

Vesting Schedules

Equity has two components: the grant of equity and the vesting schedule of the equity. Granting equity does not necessarily mean that you actually own it right away. In nearly all cases, your equity grant is subject to vesting – even for the CEO! Vesting determines when you can gain actual ownership of your equity grant over time, ensuring long-term commitment to the business. Vesting also prevents executives (and even company founders) from walking away with significant ownership of the company after a short-term stint of employment. Common vesting types include:

• Time-Based Vesting: Employees earn their promised equity gradually, often over four years—typically every quarter. If your vesting schedule includes a one-year cliff, that means that you would get nothing if your employment terminates within the first 12 months. One-year cliffs are very common for company founders but can also apply to lower-level employees. The cliff ensures employees (including executives) remain with the company for at least a year, which gives everyone enough time to assess if there’s a good mutual fit before the first tranche of equity.
• Performance-Based Vesting: Equity vests upon achieving specific milestones, such as revenue targets or company valuation goals.
• Hybrid Approaches: Some companies combine time-based and performance-based vesting to balance retention incentives with strategic growth.

Equity Types: RSUs vs. Stock Options

Understanding stock types is absolutely crucial to maximize the value and navigate their tax implications.

Restricted Stock Units (RSUs): RSUs are by far the easiest form of equity compensation to manage. They are actual shares in the company. You can receive grants when you join the company and then again every year. In either case, the grants are subject to vesting. RSUs are taxed as income every time they vest, simplifying the process compared to stock options. So, the mere grant of RSUs is not taxable because you haven’t earned it yet until a portion of it actually vests. RSUs are common in public companies where liquidity – and the value of the stock – is predictable.

Stock Options: Unlike RSUs, the mere grant of a stock option gives you absolutely no ownership in the company – even if the options fully vest! And this is because a stock option only gives you the right – but not the obligation -- to purchase the stock with your own money at a discounted “strike price” within a specific timeframe (usually 10 years). And you can exercise your option to buy the stock only after the option has vested and before the option expires. But whether you actually exercise your option and buy the stock at the strike price during that window is totally up to you.

Two Types of Stock Options: ISOs and NSOs

There are two types of stock option compensation – and they work very differently based on how they’re taxed. Navigating the tax implications and intricacies are best handled by a tax professional.

Employee Stock Purchase Plans (ESPP)

Many publicly traded companies also offer an optional type of equity compensation called Employee Stock Purchase Plans. ESPPs give employees the option to direct a portion of their paycheck into company stock, which is then purchased at a discount. Typically employees are given the option to participate in an ESPP twice per year; the maximum annual contribution is $25,000. Participating employees have money deducted from each paycheck during the ESPP period. At the end of that period, shares are bought at a discount off either at the price of the start of the ESPP period or at the end of the ESPP period–whichever is lower.

Because these shares are bought with after-tax money, they are only taxed when sold. Unlike stock that you buy on your own through a brokerage account, ESPP shares only receive long term capital gains treatment if held for more than two years.
