How to sell your Climeworks shares

Hold vested shares or options in Climeworks (climate tech, Switzerland)? Here's how a private secondary sale works, the rules that apply in Switzerland, who buys, and what to expect.

Climeworks is a private climate tech company headquartered in Switzerland. If you hold vested shares or options in Climeworks and want to turn part of that into cash before an IPO or acquisition, this is a plain-English guide to how a private secondary sale actually works — and what's specific to Climeworks and to Switzerland.

Can you sell Climeworks shares before an exit?

Often, yes. Selling existing shares you own in a private company to a private buyer, before the company is sold or lists, is called a secondary sale. It's possible for Climeworks shares if they're vested and transferable, and once you've cleared Climeworks's transfer rules. There's no public market for a private company, so a sale is a private, negotiated transfer — not a click of a button.

What you probably hold

First, pin down what you actually have. In Switzerland, startup equity is usually held as stock options or shares. You can generally only sell shares, so if you hold options you typically exercise them (pay the strike price to convert them into shares) before you can sell. Check your grant documents for your vested amount, strike price and any deadlines.

The rules that apply in Switzerland

How a sale works, and how it's taxed, depends on the rules in Switzerland — transfer formalities, any right of first refusal, and the tax on a gain. We've written a dedicated plain-English guide: how to get liquidity from startup equity in Europe. Read it alongside this page.

Who buys Climeworks shares

There are four realistic buyers, roughly in order: Climeworks itself (if it runs a buyback or tender), existing investors or shareholders (often via a right of first refusal), the investor in Climeworks's next funding round, and — when those don't apply — a private individual investor who wants exposure to Climeworks. Recognisable names like Climeworks tend to attract private-investor interest; the hard part is finding that buyer discreetly, which is the gap we fill.

What to expect on price

A private, minority, all-cash secondary usually happens at a discount to Climeworks's last headline valuation — because the buyer takes an illiquid stake with no guaranteed exit, and because you likely hold common shares, which are worth less than investors' preferred shares. That's normal, not a trick. See what discount is fair for a realistic range.

Can I sell my Climeworks shares before an exit?
