Convertible Promissory Note financial
"Alpha Wave Ventures holds a Convertible Promissory Note in the aggregate principal amount"
A convertible promissory note is a loan a company takes now that can later be turned into shares instead of being repaid in cash. Think of it as lending money with the option to accept ownership in the business down the road; that matters to investors because it affects who gets paid first, how much ownership existing shareholders keep, and the company’s future valuation and cash needs. Terms such as conversion price, interest and maturity determine the financial impact.
reverse split financial
"convertible into 0.741 shares of the Issuer's Class A common stock (after giving effect to the one-for-1.349 reverse split"
A reverse split is when a company reduces the number of its outstanding shares by combining several existing shares into one new share, so the price per share rises proportionally while the company’s overall value stays the same. Investors care because it can make a stock appear more respectable or meet exchange rules — like turning many small coins into a single larger bill — but it can also signal financial trouble and often affects trading liquidity and investor perception.
Reclassification financial
"shares will then be reclassified into shares of Common Stock pursuant to the Reclassification"
Reclassification is the formal change in how an asset, liability, security, transaction, or business activity is labeled on financial records or under rules. It matters to investors because the new label can alter reported profits, tax treatment, ownership rights or perceived risk—much like moving an item from 'personal' to 'business' use, it doesn't create value by itself but can change comparisons, taxes, and who controls outcomes.
Rule 16b-7 regulatory
"reclassification of each share of Class A common stock into one share of common stock in an exempt transaction pursuant to Rule 16b-7"
A U.S. Securities and Exchange Commission safe-harbor rule that shields corporate insiders (officers, directors and large shareholders) from automatic short-swing profit claims when they buy or sell their company’s stock under a pre-approved, written plan that follows specific timing and nondiscretionary rules. For investors, the rule matters because it distinguishes routine, formula-driven insider transactions from opportunistic trades that could trigger automatic profit recoveries—think of it as an approved autopilot for insider trading that reduces legal uncertainty when the plan’s conditions are met.
Section 16 of the Securities Exchange Act of 1934 regulatory
"For purposes of Section 16 of the Securities Exchange Act of 1934, each of the Reporting Persons expressly disclaims"
A provision of federal securities law that requires company insiders—directors, officers and large shareholders—to publicly report their stock holdings and trades and to surrender any “short-swing” profits from purchases and sales within a six-month window. It acts like a rule that forces leaders to announce their trades and prevents quick buy-sell windfalls, giving investors transparency into insider activity and reducing opportunities for unfair gain.
pecuniary interest financial
"disclaims beneficial ownership of the securities reported herein except to the extent of his or its pecuniary interest therein"
