reverse stock split financial
"The Certificate of Amendment effected a reverse stock split of the Company’s common stock at a ratio of 1-for-3"
A reverse stock split is when a company reduces the number of its shares outstanding, making each share more valuable. For example, if you own 100 shares worth $1 each, a 1-for-10 reverse split would turn your 100 shares into 10 shares worth $10 each. Companies often do this to boost their stock price and appear more stable to investors.
Certificate of Amendment regulatory
"the Company filed a Certificate of Amendment to the Company’s Third Amended and Restated Certificate of Incorporation"
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.
Third Amended and Restated Certificate of Incorporation regulatory

CUSIP number financial
"The new CUSIP number for the Company’s common stock is 26614N 201."
A CUSIP number is a nine-character code that uniquely identifies a specific U.S. or Canadian stock, bond, or other security, similar to a barcode or a social-security number for a financial instrument. It matters to investors because it removes confusion between similar securities, ensures trades and settlements are applied to the correct issue, and helps locate official documents and transaction records quickly.
