Key Terms

form s-3, shelf registration statement, at-the-market program, series a warrants, +4 more

8 terms

form s-3 regulatory

"filed a shelf registration statement on Form S-3 that would allow it to offer"

Form S-3 is a legal document companies use to register their stock sales with the government, making it easier and faster for them to raise money by selling shares to investors. It’s like having a pre-approved shopping list that lets a company quickly sell new shares when they need funds, without going through a lengthy approval process each time.

shelf registration statement regulatory

"has filed a shelf registration statement on Form S-3 that would allow it"

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.

at-the-market program financial

"established an at‑the‑market program to sell up to $6,000,000 of common stock"

An at-the-market program is a way for a company to sell new shares of its stock gradually over time directly into the stock market, rather than all at once. This approach allows the company to raise money as needed while giving investors the opportunity to buy shares at current market prices. It helps manage the timing and price of new stock offerings, providing flexibility for both the company and investors.

series a warrants financial

"Series A warrants, each exercisable for one share of common stock at an exercise price"

Series A warrants are financial tools that give the holder the right to buy shares of a company at a specific price within a certain period. They are often issued alongside investments to provide additional potential profit if the company's value increases. For investors, they can offer a chance to benefit from future growth without committing immediate capital to buying shares.

right-of-use lease asset financial

"The company recorded a right‑of‑use lease asset of $244,793 and related lease liabilities"

A right-of-use lease asset is the amount a company records on its balance sheet to show the value of its contractual right to use leased property or equipment over the lease term. Think of it like the recorded value of a long-term rental agreement—paired with a matching lease liability—and it matters to investors because it affects reported assets, debt levels, and profit timing, which influence assessments of a company’s financial strength and cash flow needs.

form s-8 regulatory

"filed a Form S-8 to register securities for issuance under its Amended and Restated"

A Form S-8 is a U.S. Securities and Exchange Commission registration that lets a public company set aside shares for employee benefit plans and stock-based compensation. Think of it as opening a dedicated account that authorizes the company to issue or reserve stock for workers and directors; it matters to investors because it enables share dilution when those awards are granted or exercised and signals how management is compensated and incentivized.

notice of allowance regulatory

"reported that it received a USPTO notice of allowance for patent application"

A notice of allowance is an official confirmation from a patent office that a patent application has met all necessary requirements and is approved for granting. It signals that the invention is likely to receive legal protection soon, which can be important for investors considering the value and exclusivity of a new product or technology. Think of it as a green light indicating that the invention is on track to become legally protected.

u.s. patent regulatory

"it was granted and issued U.S. Patent No. 12,524,507 by the U.S. Patent"

A U.S. patent is a government-granted right that gives its holder exclusive control over making, using, selling or importing a specific invention inside the United States for a limited time. Think of it like owning the only key to a locked box or a secret recipe for a product. For investors, patents can create a legal barrier against competitors, boost potential sales or licensing income, and therefore increase a company’s value — but they also require time and money to obtain and defend, and their protection ends when they expire.

Company developing privacy-first agentic platform for social media

NEW BRUNSWICK, N.J., April 15, 2026 (GLOBE NEWSWIRE) -- Myseum, Inc. (Nasdaq: MYSE) (“Myseum” or the “Company”), a privacy-first social media and technology innovator, today announced that it is now operating under the new name Myseum.AI, Inc. effective April 15, 2026. The rebrand illuminates the Company’s core technology platform that will integrate proprietary privacy-first artificial intelligence (AI) into its secure messaging and social media platforms. The Company is developing privacy-first agentic localized AI agents that assist in managing personal media such as photos, videos and messages, while maintaining privacy. The technology adapts to individual patterns and preferences to better assist the user while maintaining data integrity and encryption to ensure that user information is never shared with any other social platforms. Essentially, the personalized AI assistant learns from the user’s individual actions and never shares that information with traditional AI models.

In conjunction with the name change, Myseum.AI stock will continue to trade on Nasdaq under the ticker symbol “MYSE.”

“As a privacy-first AI and social media technology company, we continue to deliver on our commitment to innovation in the secure digital media space through our development of popular privacy-first user platforms. Our new name, Myseum.AI, identifies our core AI-based technology that secures our multi-tiered social media ecosystem,” said Darin Myman, CEO of Myseum.

About Myseum, Inc.

Myseum, Inc. (formerly DatChat Inc.) is a privacy-focused AI and social media technology company developing innovative platforms for secure digital sharing and storage. Its flagship platform, Picture Party, is a next-generation patented instant social networking experience designed to make it easier, more fun and private to share. The platform enables users to create curated albums, build encrypted galleries with controlled access, personalize their content feeds, and organize collections within a broader digital ecosystem. Picture Party by Myseum is currently available at the iOS app store and Google Play store, with a desktop version expected later this year.

Built on patented technology and proprietary software, Picture Party by Myseum’s platform is an instant private social network for any occasion designed to make it easier, more fun and private to share. The platform enables individuals, families and groups to securely store and share messages, photos, videos within a private, multi-layered digital library, with a focus on privacy, control and long-term accessibility. The Company also operates DatChat Messenger & Private Social Network, which extends this focus on privacy by giving users greater control over their communications, including the ability to determine how long messages can be viewed, delete messages or entire conversations after sending, prevent screenshots and protect encrypted content stored on devices, all while maintaining a familiar messaging experience.
