ATM Prospectus regulatory

"this Prospectus Supplement amends and supplements certain information in the prospectus"

A prospectus for an "at-the-market" (ATM) offering explains a company’s plan to sell newly issued shares directly into the open market over time, at prevailing prices, through one or more broker-dealers. Investors should care because it creates a standing ability for the company to raise cash quickly and incrementally—like an open tab the company can draw on—which can dilute existing shareholders and affect share price and supply.

ATM Sales Agreement financial

"pursuant to the terms of the certain ATM Sales Agreement, dated May 3, 2024"

An ATM sales agreement is a standing arrangement that lets a company sell its shares directly into the open market at prevailing prices, often through a broker, instead of selling a large block all at once. Investors care because it gives the company a flexible, on-demand way to raise cash but can slowly increase the number of shares outstanding and put downward pressure on the stock price—think of it like drip-feeding new supply into a marketplace.

public float financial

"aggregate market value of our outstanding common stock held by non-affiliates"

Public float is the total number of a company's shares that are available for trading by the general public. It excludes shares held by company insiders or large stakeholders who are unlikely to sell them easily. This figure helps investors understand how much of the company's stock is actively available, which can influence its liquidity and how easily its price might change.

During the twelve calendar months prior to, and including, the date hereof, we have sold an aggregate of 1,203,544 shares of our Common Stock, as adjusted to reflect the one-for-fifteen reverse stock split effected on September 29, 2025, for aggregate gross proceeds of approximately $12.7 million through Wainwright under the Agreement. This Prospectus Supplement should be read in conjunction with the ATM Prospectus, and is qualified by reference thereto, except to the extent that the information herein amends or supersedes the information contained in the ATM Prospectus.
