"shares issuable upon conversion of ... convertible promissory notes"

A convertible promissory note is a loan a company takes that can later be turned into shares instead of being paid back in cash; think of lending money now in exchange for a voucher that can become ownership later. Investors care because it mixes credit risk and potential ownership upside—it can protect lenders if a company struggles while also diluting existing shareholders when converted, affecting future share value and investor returns.

fixed conversion price financial

"which have a fixed conversion price of $0.10 per share"

Park Consulting Warrant financial

"shares issuable upon exercise of a five-year warrant"

gross proceeds financial

"up to an aggregate of $180,000 in gross proceeds"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.
