pre-funded warrants financial
"not the maximum number of pre-funded warrants (or shares of common stock"
Pre-funded warrants are financial instruments that give investors the right to purchase a company's stock at a set price, but with most or all of the purchase price paid upfront. They function like a coupon or gift card for stock, allowing investors to buy shares later at a fixed price, which can be beneficial if they want to avoid future price increases. This makes them important for investors seeking flexibility and certainty in their investment plans.
Securities Purchase Agreement financial
"The Company is seeking requisite approval from the Purchasers to amend the Securities Purchase Agreement"
A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.
forward-looking statements regulatory
"These statements may be “forward-looking statements” within the meaning of Section 21E"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Item 1.01 Entry Into A Material Definitive Agreement.

 

On August 31, 2026, Shuttle Pharmaceuticals Holdings, Inc. (the “Company”) and United Dogecoin Inc. (“United Dogecoin”), a wholly-owned subsidiary of the Company as a result of the consummation on May 6, 2026 of that certain transaction contemplated by the Agreement and Plan of Merger dated April 30, 2026 (the “Merger Agreement”), by and among the Company, United Dogecoin and Shuttle Merger Sub, Inc., entered into a First Amendment to Merger Agreement (the “Amendment”). The Amendment amends the definition of “Milestone Event” (as defined in the Merger Agreement) by reducing the number of Mining Rigs (as defined in the Merger Agreement) from 2,000 to 500. No other terms of the Merger Agreement were amended or modified by the Amendment, and only the threshold for satisfying the Milestone Event has been amended and not the maximum number of pre-funded warrants (or shares of common stock underlying pre-funded warrants) that would be issuable or issued as a result of satisfying the Milestone Event.

 

A copy of the Amendment is attached to this Current Report on Form 8-K as Exhibit 10.1, and is incorporated by reference herein.

 

The Company is seeking to effect similar amendments to the definition of “Milestone Event” (the “Parallel Amendments”) found in the Company’s:

 

Securities Purchase Agreement (the “Securities Purchase Agreement”), which it entered into on April 30, 2026 with certain accredited investors (the “Purchasers”), pursuant to which the Company issued (i) 1,910 shares of Series B-2 convertible preferred stock, par value $0.00001 per share and (ii) common stock purchase warrants (the “PIPE Financing”), which PIPE Financing closed on May 6, 2026; and

 

Second Amendment (the “Second Amendment”) to Asset Purchase Agreement dated as of November 20, 2025, which it entered into on April 30, 2026 with 1563868 B.C. Ltd., a Canadian limited corporation and the Company’s wholly owned subsidiary, 1542770 BC Ltd., a Canadian limited corporation, and ZhiTian (Andy) Zhang.

 

The Company is seeking requisite approval from the Purchasers to amend the Securities Purchase Agreement, and from the parties to the Second Amendment to amend the Second Amendment, to effect the Parallel Amendments.
