DynaResource investor buys 1.9M units for $861K

Amendment No. 9 to the Schedule 13D details a new $861,250 unit financing and updated ownership stakes in DynaResource.

Rhea-AI Filing Summary

DynaResource, Inc. (DYNR) received a new equity investment from Golden Post Rail, LLC, disclosed in Amendment No. 9 to a Schedule 13D. On September 1, 2026, Golden Post purchased 1,913,889 units at $0.45 per unit, each unit consisting of one common share and a warrant to buy one share at an exercise price of $0.51, for aggregate consideration of $861,250.05.

The warrant is exercisable only after approval and filing of a charter amendment to increase authorized common shares or effect a reverse stock split, and remains exercisable until the later of 180 days after issuance or 30 days after that condition is satisfied. Following the transaction, Golden Post reports beneficial ownership of 4,987,579 shares (13.3%), Matthew K. Rose reports 7,479,058 shares (19.9%), and MKR 2022 Grantor Retained Annuity Trust reports 1,755,000 shares (4.69%), including shares issuable upon conversion of derivative securities.

Filing Explained

The warrant remains gated on an uncompleted charter change, while the agreed path could enable additional shares and dilute existing ownership if exercised.

This Schedule 13D amendment discloses a company commitment to prepare and file a proxy statement and convene a stockholder meeting; the charter change is proposed, not reported as approved or filed, so the warrant is not yet exercisable.

The proposed Charter Amendment would either increase authorized common shares or effect a reverse stock split, to satisfy reservation obligations for the warrant and all stated outstanding derivative securities, equity awards, and incentive plans. A proxy statement presents matters shareholders vote on, while a reverse stock split reduces the share count and proportionally raises the per-share price without changing company value by the split itself. Golden Post agreed to vote all of its shares entitled to vote at the meeting in favor of the amendment and waived certain preemptive and antidilution rights for 120 days.

If the warrant shares are later issued, the additional shares would reduce existing holders’ percentage ownership absent offsetting changes; the filing’s disclosed state is a warrant awaiting the Authorized Shares Condition, not an issuance of those warrant shares.

Securities Purchase Agreement financial

"Golden Post entered into a Securities Purchase Agreement with the Issuer"

A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.

Warrant financial

"each unit consisting of one share of Common Stock and one warrant"

A warrant is a time-limited financial contract that gives its holder the right to buy a company's shares at a set price before a specified date, like a coupon that lets you purchase stock at a fixed discount for a limited time. It matters to investors because warrants offer leveraged exposure to a stock’s upside and can dilute existing shareholders if exercised, so they affect potential gains and the company’s outstanding share count.

Grantor Retained Annuity Trust financial

"MKR 2022 Grantor Retained Annuity Trust"

A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.

reverse stock split financial

"to either increase its number of authorized shares ... or effect a reverse stock split"

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.

Registration Rights Agreement financial

"Amended and Restated Registration Rights Agreement, dated as of May 14, 2020"

A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.

beneficial owner financial

"the beneficial owner of any securities covered by this"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.
