At The Market Offering Agreement financial
"entered into an At The Market Offering Agreement (the “Sales Agreement”) with H.C. Wainwright"
shelf registration statement regulatory
"being registered under the Securities Act pursuant to the Company’s shelf registration statement on Form S-3"
A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.
prospectus supplement regulatory
"and an accompanying prospectus supplement filed with the SEC on April 8, 2026"
A prospectus supplement is an additional document provided alongside a company's main offering details, offering updated or extra information about a specific financial product being sold. It helps investors understand the latest terms, risks, and details of the investment, similar to how an update or revision clarifies or expands on original instructions, ensuring they have current and complete information before making a decision.
Rule 415(a)(4) regulatory
"“at the market offerings” as defined in Rule 415(a)(4) under the Securities Act"
Rule 415(a)(4) is a U.S. Securities and Exchange Commission rule that lets a company add more securities to an already effective shelf registration, so those additional shares or bonds can be sold later without filing a completely new registration. For investors it matters because it gives the issuer the flexibility to raise cash quickly—like having an open credit line—while creating the possibility of dilution or changes in supply that can affect share price.
emerging growth company regulatory
"Emerging growth company"
An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

Item 1.01
Entry into a Material Definitive Agreement.
 
On April 8, 2026, Phio Pharmaceuticals Corp. (the “Company”) entered into an At The Market Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC, as sales agent (the “Sales Agent”), pursuant to which the Company may offer and sell, from time to time, through the Sales Agent, shares of the Company’s common stock, par value $0.0001 per share (the “Shares”). The offering and sale of up to $6,360,000 of the Shares pursuant to the Sales Agreement is being registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-279557), which was declared effective by the Securities and Exchange Commission (“SEC”) on July 1, 2024, which includes a base prospectus, and an accompanying prospectus supplement filed with the SEC on April 8, 2026.
 
Subject to the terms and conditions of the Sales Agreement, the Sales Agent will use its commercially reasonable efforts to sell the Shares from time to time, based upon the Company’s instructions. The Company provided the Sales Agent with customary indemnification rights and contribution rights, including for liabilities under the Securities Act, and the Sales Agent will be entitled to a commission of 3.0% of the gross proceeds from each sale of the Shares. In addition, the Company agreed to reimburse certain expenses incurred by the Sales Agent in connection with the Sales Agreement, including up to $75,000 for reasonable and documented fees and expenses incurred by the Sales Agent’s legal counsel in connection with entering into the transactions contemplated by the Sales Agreement, excluding periodic due diligence fees as set forth in the Sales Agreement.
 
Sales of the Shares, if any, under the Sales Agreement may be made in transactions that are deemed to be “at the market offerings” as defined in Rule 415(a)(4) under the Securities Act. The Company will designate the parameters for the sale of Shares, if any, including the number of Shares to be issued, the time period during which sales are requested to be made, limitations on the number of Shares that may be sold on any trading day and any minimum price below which sales may not be made. The Company has no obligation to sell any of the Shares and may at any time suspend offers under the Sales Agreement or terminate the Sales Agreement. The Sales Agent is not obligated to purchase any Shares on a principal basis pursuant to the Sales Agreement, except as otherwise specifically agreed by the Sales Agent and the Company in a separate agreement. No assurance can be given that any Shares will be sold under the Sales Agreement, or if such sales occur, no assurance can be given as to the price or number of Shares that will be sold, or the dates on which any such sales will take place.
 
The Sales Agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the Sales Agent and other obligations of the parties.
 
The information set forth herein shall not constitute an offer to sell or the solicitation of any offer to buy the Shares, nor shall there be an offer, solicitation or sale of the Shares in any state in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of such state.
