At The Market Offering Agreement financial
"entered into that certain At The Market Offering Agreement (the “Sales Agreement”)"
An at-the-market offering agreement is a contract that lets a company sell newly issued shares directly into the open market through a broker, at whatever price the stock is trading at that moment. For investors this matters because it can increase the number of shares available (which may dilute existing ownership) while providing a flexible, often faster way for the company to raise cash without fixing a price, similar to a vendor selling small batches at current market stalls rather than setting a single fixed price.
shelf registration statement on Form S-3 regulatory
"pursuant to the Company’s shelf registration statement on Form S-3 (Registration No. 333-284663)"
A shelf registration statement on Form S-3 is a pre-approved filing with the Securities and Exchange Commission that lets an eligible public company register securities in advance and sell them later in one or more offerings without repeating the full registration process. Think of it like a pre-approved funding line: it gives management the flexibility to raise capital quickly when market conditions are right, a move that can affect share supply, dilution and investor returns, so investors monitor it as a signal of potential financing activity.
prospectus supplement regulatory
"a prospectus supplement which was filed with the SEC on May 1, 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.
emerging growth company regulatory
"Emerging growth company Item 1.01 Entry into a Material Definitive Agreement."
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.
aggregate offering price financial
"issuable pursuant to the ATM Offering to up to an aggregate offering price of up to $7,500,000"
The aggregate offering price is the total dollar amount that will be raised if all the securities in an offering are sold at the stated offering price, before fees or expenses are taken out. Investors use it to gauge the size of the fundraising and its potential effects—such as how much cash the company will get and how much existing ownership might be reduced—similar to totaling every item’s price in a shopping cart to see the full bill.
