Series B Non-Voting Convertible Preferred Stock financial
"Certificate of Designation of Preferences, Rights, and Limitations of Series B Non-Voting Convertible Preferred Stock."
A Series B non-voting convertible preferred stock is a class of company shares that gives holders financial priority—such as fixed dividends and first claim on assets if the company is sold—while not granting voting rights. It can be converted into regular common shares under set conditions, which matters to investors because conversion can increase upside participation but also dilute existing owners; the preference reduces downside risk like a safety buffer.
Mandatory Conversion financial
"the Issuer may elect to convert ... in a "Mandatory Conversion"."
Mandatory conversion is a rule that forces certain convertible securities—like bonds or preferred shares—to be turned into common stock when specific conditions are met (for example, a date arrives or a price target is hit). For investors this matters because it increases the number of shares outstanding and can dilute existing ownership, shifting value from fixed-income holders into equity holders and changing a company’s risk and return profile, much like an automatic trade that swaps a guaranteed payment for an ownership stake.
Conversion Ratio financial
"calculated based on the Conversion Ratio (defined as 1,000 shares of Common Stock issuable..."
The conversion ratio is the number of common shares an investor receives when a convertible security (like a bond or preferred share) or an exchangeable instrument is turned into ordinary stock. It matters because it tells investors how much ownership or dilution will occur — similar to knowing how many slices you get when you trade in a coupon — and directly affects the value you get from the convertible and the company’s future share count.
Certificate of Amendment regulatory
"the Issuer filed a Certificate of Amendment (the "Amendment") to the Certificate of Designation..."
A certificate of amendment is an official filing that updates a company’s founding documents—its legal “rulebook” that sets share structure, voting rules, name and basic purpose. Think of it like changing the blueprint of a building: small changes are paperwork, big ones can alter who owns how much and who controls decisions. Investors watch these filings because they can affect share counts, voting power, dilution and company value.
