NON INVASIVE MONITORING SYSTEMS INC /FL/ Files Amended S-1: RSU & Capital Gains Tax Exposure Calculator (Oct 6, 2026)

What Changed

Non-Invasive Monitoring Systems Inc filed an S-1/A on October 6, 2026, amending its registration for a public listing. The filing updates a prior S-1 originally submitted for review, signaling the issuer is closer to pricing shares for trading. The company submitted an 18MB disclosure package, consistent with a company revising financials, risk factors, or share structure ahead of an offering window.

The Numbers That Matter

Filing Stage	Typical Timeline to Pricing	Disclosure Size Signal	Investor Action Window
Initial S-1	60 to 90 days	Base financials, risk factors	Monitoring only
S-1/A (first amendment)	30 to 60 days	Updated financials, SEC comment responses	Watchlist entry
S-1/A (this filing, 18MB)	15 to 45 days	Expanded disclosure, likely near-final terms	Active position sizing
Effective registration	0 to 5 days	Final prospectus, pricing range set	Allocation decision

What This Means for Your Portfolio

An S-1/A filing of this size at this stage typically indicates a company nearing SEC effectiveness, not an early-stage registration. Micro-cap medical device issuers historically price with wide bid-ask spreads in the first 90 days, and the after-tax outcome depends heavily on whether the position is held in a taxable account or a tax-advantaged wrapper.

Scenario Analysis

Position Size	Allocation at 5%	Short-Term Gain Scenario (plus 30%, taxed at 37% ordinary)	Net After-Tax Proceeds
$500K	$25,000	$32,500 gross	$20,488
$1M	$50,000	$65,000 gross	$40,950
$2M	$100,000	$130,000 gross	$81,900

Micro-cap IPOs in the medical device and diagnostics space frequently see first-week volatility exceeding 30% in either direction. The after-tax figures above assume a holding period under 1 year, which triggers ordinary income tax rates rather than long-term capital gains treatment.

Frequently Asked Questions

Q: What does an S-1/A filing mean versus the original S-1? A: An S-1/A is an amended registration statement, and this is a sign the company is responding to SEC comments ahead of a possible effective date within 15 to 45 days.

Q: Does a larger filing size, 18MB in this case, indicate anything specific? A: A larger amendment typically means expanded financial disclosures or additional risk factor detail, often a precursor to final pricing terms.

Q: How should investors in pending small-cap medical device IPOs approach position sizing? A: Investors should consider their total portfolio size, existing healthcare sector exposure, and risk tolerance. Allocation decisions depend on individual financial circumstances and should be made in consultation with a qualified financial advisor.

Q: What is the tax treatment if shares are sold within the first year of an IPO allocation? A: Ordinary income tax rates of up to 37% federal apply to gains on positions held under one year, compared to a maximum 20% for positions held over one year.
