Leaving Tierra Biosciences? Mind the window.

If you hold options, leaving usually starts a post-termination exercise clock, often 90 days. Miss it and vested options can expire worthless; exercise blindly and you may owe real money (including possible AMT) on shares you can't yet sell. Neither panic nor autopilot is a plan. Knowing your window, your exercise cost, and the current estimated price is.

Tierra Biosciences equity, answered plainly

Is Tierra Biosciences a public company?

No. Tierra Biosciences is privately held, which is exactly why its share price doesn't show up in your brokerage app. Its shares still change hands between eligible buyers and sellers on the secondary market, producing an observable estimated price.

What is Tierra Biosciences's stock price?

Tierra Biosciences has an observed estimated share price from secondary-market activity, updated as new data is observed. ExitCue members see the current estimate and its full history free, along with what their own grants are approximately worth at that price.

Can you sell Tierra Biosciences stock before an IPO?

Sometimes. Private-share sales depend on Tierra Biosciences's transfer restrictions, rights of first refusal, and whether the company runs tender offers or permits secondary sales. Your grant documents and the company's policies govern, but "hard to sell today" is not the same as "worth zero."

What happens to my Tierra Biosciences options if I leave?

Most option grants have a post-termination exercise window, commonly 90 days, sometimes longer, after which unexercised options expire worthless. The exact terms are in your grant documents. ExitCue reads those documents, tracks the deadline, and reminds you before the window closes.

How much is my Tierra Biosciences equity worth?

Multiply what you hold by the estimated share price, separating vested from unvested, and netting out strike prices for options. That's precisely the arithmetic ExitCue does for you, continuously, at the current observed estimate. It's an educational estimate, not a guarantee, and a far better anchor than the $0 the internet suggests.

What's the difference between Tierra Biosciences's 409A valuation and what its shares trade at?

The 409A is a tax-compliance appraisal, usually conservative, used to set option strike prices. Secondary-market pricing reflects what buyers and sellers actually agree to. The two frequently differ, which is why evaluating an offer on the 409A alone undersells (or oversells) it.

When will Tierra Biosciences IPO?

Unless Tierra Biosciences has publicly announced a listing, nobody knows, including the people who sound confident on forums. The practical upside of secondary markets is that you don't have to wait for an IPO to know approximately what the shares trade at.

Do my unvested Tierra Biosciences RSUs count for anything?

Unvested equity isn't yours yet, but it has an estimable value and a schedule. Seeing vested and unvested value separately, in dollars at the current estimated price, turns "some RSUs" into a number you can plan around.
