If you work at a publicly traded space or defense company, there’s a good chance RSUs are a meaningful part of your compensation. And there’s an equally good chance you have not given them much thought beyond watching the share price.

That’s a problem. The decisions you make around your RSUs, or don’t make, can have a real impact on your tax bill, your financial security, and how much of that equity you keep.

This is not generic stock compensation advice. The space and defense world comes with its own financial dynamics that most RSU content completely ignores. Let’s fix that.

RSU Meaning: What Are RSUs

A Restricted Stock Unit (RSU) is a promise from your employer to deliver company stock once certain conditions are met. At most space and defense companies, that condition is time. Stay employed through a vesting schedule and the shares are yours.

RSUs are not actual shares when they are granted. They become shares only when they vest. Until that happens, they cannot be sold, transferred, or used. Once they vest, the stock is delivered and becomes your property. At that point, taxes kick in immediately.

How RSU Stock Is Taxed

When RSUs vest, the value of the shares is treated as ordinary income, just like a bonus. This income is subject to federal income tax, state income tax where applicable, and Social Security and Medicare taxes.

Most employers automatically withhold shares to cover a portion of this tax. The problem is that standard withholding rates are often flat, typically 22% federally, and if you’re earning well into six figures at a space or defense company, your actual tax rate is probably higher than that. The gap between what gets withheld and what you actually owe can surprise people in April.

After vesting, any future change in the stock price is taxed separately. Sell later at a higher price and the additional gain may be taxed as a capital gain. If the price falls, you may realize a capital loss when sold.

That split tax treatment, ordinary income at vest and capital gains treatment after, is exactly why RSUs require a plan.

What Makes RSUs Different in the Space and Defense World

Here’s what most generic RSU content misses.

Volatility is real, specifically in this industry. Smaller space and defense companies are heavily dependent on government contracts, program funding, and geopolitical cycles. A contract win can move the stock significantly. So can a loss, a program delay, or a budget cut in Washington. Your RSUs vest into a stock that can swing hard based on factors completely outside the company’s control. Holding a large position without a plan is a real risk.

Your financial life is already concentrated here. Your salary comes from this company. Your benefits come from this company. Your career trajectory is tied to this company. Adding a large, undiversified stock position on top of that means a single bad quarter or a lost contract doesn’t just affect your portfolio. It potentially affects everything at once. That is a level of concentration risk that deserves serious attention.

The mission matters, and it can cloud financial judgment. People in the space and defense industry tend to believe deeply in what they are building. That is one of the things that makes this world different. But conviction in the mission is not the same as conviction in the stock. Holding RSUs purely out of loyalty to the company is a financial decision, and it should be treated like one.

How to Plan Around RSUs

Good RSU planning starts before the shares vest, not after.

First, understand your vesting schedule. Knowing when RSUs vest lets you anticipate income spikes and potential tax consequences. Large vesting events can push you into a higher tax bracket or trigger additional taxes. At companies with aggressive equity grant programs, this can happen more than once a year.

Second, decide whether to hold or sell once RSUs vest. Many employees default to holding because they believe in the company. But holding RSUs increases concentration risk, and in the space and defense world, that risk is already elevated by the nature of the industry. There’s no objectively right answer, but it should be a deliberate decision, not a default.

Third, plan for taxes beyond withholding. Standard withholding may not cover your actual liability. If your total income pushes you into the 32% or 37% bracket, you may owe more than what was withheld. Working with a tax professional before a large vest, not after, gives you time to adjust withholding or set aside the difference.

Fourth, think about what you would do in a liquidity event or major company transition. Space and defense companies are bought, merged, taken private, and restructured. If that happens, your vesting schedule, your holding period, and your tax situation can all change quickly. Having a plan means you can move decisively when the window is open.

The Bottom Line of RSUs and What You Need to Know Before Your Next Vest

RSUs are valuable. But the value you keep depends on how you handle them. In an industry as dynamic as space and defense, that means thinking through the tax implications, the concentration risk, and the hold-or-sell decision before shares start vesting. Not after.
