Insights

CERO adds 10% convertible debt with variable-price equity conversion.

CERO Therapeutics has put in place an amended and restated promissory note for up to $1,413,600, replacing a prior note from May 28, 2026. The instrument carries a 10% annual interest rate and matures on May 28, 2027, adding a defined near‑term debt obligation.

The note is convertible at the lesser of $0.05 per share or 80% of the average of the five lowest intraday trading prices over the 20 days before conversion, with a 4.99% beneficial ownership limitation. This structure ties potential share issuance to future market prices.

The company committed to file a Form S-1 or S-3 registering resale of conversion shares, and relied on Section 4(a)(2) and Rule 506(b) for the initial issuance. Actual dilution and cash outflows will depend on future conversion elections and whether the note remains outstanding through May 28, 2027.

6 terms

amended and restated promissory note financial

"entered into an amended and restated promissory note (the “Note”) with SRX Health Solutions, Inc."

beneficial ownership limitation financial

"subject to certain adjustments and limitations, including a beneficial ownership limitation of 4.99%."

A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.

Section 4(a)(2) of the Securities Act regulatory

"The issuance of the Note was made in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended"

A legal exemption that allows a company to sell securities directly to a limited group of buyers without registering the offering with the Securities and Exchange Commission. Think of it like a private sale among known parties rather than a public auction: it can speed fundraising and reduce disclosure requirements, but it also means less public information, lower liquidity and resale restrictions—factors investors should consider when weighing risk and exit options.

Rule 506(b) regulatory

"and Rule 506(b) promulgated thereunder."

Rule 506(b) is a U.S. securities exemption that lets companies sell shares or debt privately without full public registration, provided sales are primarily to accredited investors, up to 35 non‑accredited but financially knowledgeable buyers, and there is no public advertising or solicitation. It matters to investors because offerings under 506(b) usually include less public disclosure than registered securities—like buying from a private seller rather than a retail store—so buyers must do more of their own fact‑checking and rely on their financial sophistication.

Form S-1 or S-3 regulatory

"a registration statement on Form S-1 or S-3, covering the resale of all of the shares"

unregistered sales of equity securities regulatory

"Item 3.02 Unregistered Sales of Equity Securities."
