How much can I invest?

With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors. With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000 are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, they are limited to investing 10% of the greater of the two amounts.

When I invest, what am I purchasing?

You are purchasing the securities described in the offering documents, such as a convertible note or SAFE. These securities represent an investment amount and may convert into equity in the future according to their terms.

How to open a Self-Directed IRA on StartEngine?

StartEngine makes it easy to invest using your retirement funds. You can open a self-directed IRA account through StartEngine. To get started, simply visit our IRA page for more information and step-by-step instructions. Already have a self-directed IRA with another provider? You can still invest on StartEngine, but please note that the process will be manual and may take longer to complete.

When will I receive confirmation of my investment?

At the close of an offering, all investors whose funds have cleared by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward. Please keep in mind that a company can conduct a series of closes or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

What will the return on my investment be?

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list securities on a secondary market or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

Can I cancel my investment?

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as Invested on your account dashboard, your investment can no longer be canceled. For Regulation A+, StartEngine allows for a four-hour cancellation period. Once the four-hour window has passed, it is up to each company to set their own cancellation policy. You may find the company’s cancellation policy in the company’s offering circular. Once your investment is canceled, there is a 10-day clearing period from the date your investment was submitted. After your funds have cleared the bank, you will receive your refund within 10 business days. Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to be sent back to the account associated with the investment.

What is the difference between Regulation Crowdfunding and Regulation A+?

Both Title III Regulation Crowdfunding and Title IV Regulation A+ help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.

Risks

A crowdfunding investment involves risk. You should not invest any funds in this offering unless you can afford to lose your entire investment. In making an investment decision, investors must rely on their own examination of the issuer and the terms of the offering, including the merits and risks involved. These securities have not been recommended or approved by any federal or state securities commission or regulatory authority. Furthermore, these authorities have not passed upon the accuracy or adequacy of this document. The U.S. Securities and Exchange Commission does not pass upon the merits of any securities offered or the terms of the offering, nor does it pass upon the accuracy or completeness of any offering document or literature. These securities are offered under an exemption from registration; however, the U.S. Securities and Exchange Commission has not made an independent determination that these securities are exempt from registration.

A Crowdfunding Simple Agreement for Future Equity (Crowdfunding SAFE) offers you the right to receive Crowdfunding Stock in Halcium Energy. The amount of Crowdfunding Stock you will receive in the future will be determined at the next equity round in which the Company raises at least $1,000,000.00 in a qualified equity financing. The highest conversion price per security is set based on a $11,000,000.00 Valuation Cap or if less, then you will receive a 20.00% discount on the price the new investors are paying. You will receive no interest on your investment. When the maturity date is reached, if the Crowdfunding SAFE has not converted then you are entitled to receive Crowdfunding Stock equal to your investment back at a price per security by dividing the Valuation Cap by the aggregate number of outstanding equity securities of the Company as of immediately prior (on a fully diluted basis).

*Bonus discount subject to adjustment of bonus discounts for StartEngine noteholders. See discount bonus below.

*In order to receive perks from an investment, one must submit a single investment in the same offering that meets the minimum perk requirement. Bonus discounts from perks will not be granted if an investor submits multiple investments that, when combined, meet the perk requirement. All perks occur when the offering is completed.

Crowdfunding investments made through a self-directed IRA cannot receive perks due to tax laws. The Internal Revenue Service (IRS) prohibits self-dealing transactions in which the investor receives an immediate, personal financial gain on investments owned by their retirement account. As a result, an investor must refuse those perks because they would be receiving a benefit from their IRA account.
