Rothe Development, Inc. Files S-1: RSU & Capital Gains Tax Exposure Calculator (Sep 8, 2026)

What Changed

Rothe Development filed a 29 MB S-1 registration statement with the SEC on September 4, 2026. The company is preparing for an initial public offering. Pre-IPO shareholders holding equity compensation face a new liquidity window and a taxable event on vesting or exercise.

The Numbers That Matter

The filing itself does not trigger a tax event. Tax liability materializes at vest for RSUs or at exercise for ISOs. If you hold unvested equity in Rothe Development, your tax bill arrives on the vest date regardless of whether shares are publicly tradable.

What This Means for Your Portfolio

For a $1M pre-IPO equity position vesting post-IPO, expect $503K in combined federal and state tax liability in California. You owe this amount even if shares remain locked up under the typical 180-day restriction. Your net proceeds after tax and lockup expiration: $497K, assuming no price movement during the lockup period. If the stock declines 20% during lockup, your net proceeds drop to $397K, but your tax bill remains $503K unless you sell other shares to offset the loss.

Scenario Analysis

The asymmetry matters. You owe tax based on vest-date fair market value. Lockup-period price declines reduce sale proceeds but do not reduce the tax owed. You need liquidity to cover the tax bill on the vest date, either from the equity sale itself (if lockup has expired) or from other assets.

The Scenario You Have Not Modeled

If Rothe Development prices the IPO below the 409A valuation used for your most recent equity grant, your unvested shares may be worth less than the strike price or grant-date value. A down-round IPO does not erase your tax obligation on prior vests, but it does mean future vests generate a smaller tax bill and lower net proceeds. Run the calculation on your specific grant dates and strike prices. The 409A valuation is not the IPO price.

Liquidity Planning Before Lockup Expiration

You cannot sell shares during the lockup period, but you owe taxes at vest. Three liquidity sources:

1. Cash reserves. If you hold $500K in cash and your tax bill is $250K, you cover the liability without selling equity. Your equity position remains intact through lockup expiration.

2. Margin loan against other assets. Borrow against a taxable brokerage account to pay the tax bill. Interest cost on a $250K margin loan at 8%: $20K annually. Repay the loan after lockup expires and you sell shares.

3. Sell-to-cover at vest. Some equity plans allow immediate sale of a portion of vested shares to cover tax withholding, even during lockup. Verify whether Rothe Development's plan includes this provision. If not, you need liquidity from another source.

Lockup expiration typically does not coincide with the tax-payment deadline. Federal and state taxes are due April 15 of the year following vest, or earlier if you owe estimated quarterly payments. If your RSUs vest in Q1 2027 and lockup expires in Q3 2027, you may owe taxes before you can sell.

IPO Price Volatility and Tax Basis

Your tax basis equals the fair market value on the vest date. If shares vest at $50 and you sell at $60 post-lockup, you owe capital gains tax on the $10 gain. If shares vest at $50 and you sell at $40, you realize a $10 capital loss. The loss offsets other gains, but it does not refund the ordinary income tax you paid on the $50 vest-date value.

First-day IPO pops and subsequent declines create this scenario frequently. A stock that prices at $40, opens at $60, and vests employee shares at $60 generates a $60 tax basis. If the stock trades back to $40 within six months, employees who sell post-lockup report a $20 capital loss but have already paid ordinary income tax on $60.

Frequently Asked Questions

Q: Does the S-1 filing date trigger a taxable event for existing equity holders?
A: No. Tax liability occurs at vest for RSUs or at exercise for stock options, not at S-1 filing.

Q: What is the typical lockup period for pre-IPO employees after an IPO?
A: 180 days from the IPO pricing date, though some agreements specify 90 or 365 days.

Q: Can I defer taxes on RSUs by not selling the shares?
A: No. RSUs are taxed as ordinary income at vest regardless of whether you sell.

Q: How do I calculate my tax liability if I hold ISOs instead of RSUs?
A: ISO taxation is complex. ISOs may be subject to alternative minimum tax (AMT) at exercise and may qualify for favorable capital gains treatment if you meet holding period requirements. Consult a tax professional for your specific grants.
