Agreed with you that convertible notes bring dilution. However, the company will need funding to fulfill purchase orders, engage on marketing, distribution, expansion and introduction of new products. What is most important is how the company manage the convertible notes by ensuring the notes are either prepaid, or the revenue generated from the use of note amount is at least higher than the interest the company will pay on the notes. Secondly, dilution is one thing, having shareholders that would hold on is another. Mind you, once prepaid or conversion are completed or a larger percentage of it has been prepaid, the share price will return to actual level, as long as the company show revenue or on the right track toward generating significant revenue.
The other open question is this - would you as an investor/shareholder invest directly in the company so that convertible note become less attractive or completely off the table? Curious to know your response.
