CYABRA, INC. Files Amended S-1: RSU & Capital Gains Tax Exposure Calculator (Sep 2, 2026)

What Changed

Cyabra Inc. filed an amended S-1 registration statement on September 1, 2026. This is the company's second amendment ahead of a planned public offering, signaling final pricing and allocation are likely weeks away. The amended filing typically precedes roadshow completion and marks the 10 to 15 day window before shares begin trading.

The Numbers That Matter

The S-1/A does not yet contain final share count or pricing. Those figures appear in the final amendment, typically filed 1 to 2 days before the first trade. For employees holding pre-IPO equity, the 180-day lock-up standard applies unless the underwriting agreement specifies early release provisions.

What This Means for Your Portfolio

If you hold Cyabra RSUs or options as an employee or early investor, your liquidity window opens 180 days post-IPO under standard terms. On a $1M pre-IPO equity position, that delay costs you the ability to rebalance or derisk for two full quarters. If the stock trades down 20% in that period, the $1M position becomes $800K before you can execute a single share sale.

Scenario Analysis

Assumes IPO prices in early September 2026. Lock-up expiration is March 2027. Tax liability on RSU vesting is calculated at ordinary income rates (37% federal for high earners) plus applicable state tax. For California residents, add 13.3%. A $1M RSU vest triggers $503K in combined federal and state tax due in the year of vesting, regardless of whether you can sell shares.

Tax Timing and Execution Risk

RSUs vest and become taxable at IPO for most employees. You owe tax on the fair market value at vest, even during lock-up. If a $1M RSU position vests at IPO and you cannot sell for 180 days, you must cover $503K in tax from other assets. If the stock drops 20% during lock-up, you pay tax on $1M but sell into an $800K market value. That $200K difference is a permanent loss, not a deduction against ordinary income.

Net proceeds assume you sell all shares at lock-up expiration and pay long-term capital gains (23.8% federal, 13.3% CA) on any appreciation beyond the IPO vest price. Depreciation from vest price to sale price does not offset the ordinary income tax owed at vest.

What To Do With This

If you hold pre-IPO Cyabra equity, calculate your tax liability now. You need $503K in liquidity per $1M of vested RSUs, due April 2027 if the IPO prices in September 2026. Do not assume you can sell shares to cover tax, as lock-up restrictions prevent share sales for 180 days. Determine whether you have sufficient cash or available lines of credit to cover the tax liability. If you cannot cover the tax without selling, you may be forced into a same-day sale election at vest, which requires advance coordination with your equity administrator and may not be available under your plan terms.

The Scenario You Have Not Modeled

Underwriting agreements often include early release provisions if the stock trades above the IPO price by a specific percentage (commonly 25% to 33%) and the company reports earnings. If Cyabra trades up 30% and reports Q4 2026 earnings in late January 2027, underwriters may release 50% of locked shares 120 days post-IPO instead of 180. That compresses the liquidity window and may move the sale into a different tax year. Confirm early release terms in the final prospectus before you finalize tax withholding strategy.

Frequently Asked Questions

Q: When does the 180-day lock-up period start? A: The lock-up starts on the first day of public trading, not the S-1 filing date or pricing date.

Q: Can I sell shares before lock-up expires to cover my tax bill? A: No, unless the equity plan allows a same-day sale election at vest, which must be arranged before the IPO prices.

Q: What tax rate applies to RSUs that vest at IPO? A: Ordinary income rates apply at vest, up to 50.3% combined federal and California state for high earners.

Q: Does stock price depreciation during lock-up reduce my tax owed? A: No. Tax is due on the fair market value at vest regardless of subsequent price movement.
