Item 1.01 - Entry into a Material Definitive
Agreement.
On each of May 15, 2026 and May 29,
2026, we received $100,000 loans from Abuse Deterrent Pharma, LLC (“AD Pharma”). On June 24, 2026, we received a $200,000
loan from AD Pharma. These loans combined with previous loans made to the Company and combined with the $2,319,279 under the November 10,
2022 Amended Consolidated and Restated Secured Promissory Note, now has a principal balance of $10,694,279 with accrued interest of approximately
$1,160,000 as of June 24, 2026 and bears interest at 5.25% (“Note”). The Events of default under the Note include, among
other items, bankruptcy events, failure to pay interest and principal when due and such failure continues for 5 days, and if Acura is
generally not, or is unable to, or admits in writing its inability to, pay its debts as those debts become due. If any amount payable
hereunder is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration, or otherwise,
including upon an event of default, such overdue amount shall bear interest at the rate per annum of 7.5% from the date of such non-payment
until such amount is paid in full.
The funding provided by AD Pharma was used to
meet day-to-day operation activity. There can be no assurance we will be successful in receiving additional financing. In the absence
of the receipt of additional financing by late July 2026, we will be required to scale back our operations, including the furlough
and lay-off of employees, or to terminate operations and/or seek protection under applicable bankruptcy laws. This could result in a complete
loss of shareholder value in the Company. Even assuming we are successful in securing additional sources of financing to fund continued
operations, there can be no assurance that the proceeds of such financing will be sufficient to fund operations until such time, if at
all, that we generate sufficient revenue from our products and product candidates to sustain and grow our operation.
The inclusion of a description of the Note under
Item 1.01 of this Current Report on Form 8-K shall not be deemed an acknowledgement that the Note is a material agreement not made,
or deemed not to be made, in the ordinary course of our business.
Item 1.01 - Entry into a Material Definitive
Agreement.
On June 29, 2026, Acura Pharmaceuticals, Inc.
(“we” “Acura” or the “Company”), received the executed agreement to further amend the June 28,
2019 License, Development and Commercialization Agreement (“Amended Agreement”) with AD Pharma, for the development of LTX-03
(hydrocodone bitartrate with acetaminophen) immediate-release tablets utilizing Acura’s patented LIMITx technology which addresses
the consequences of excess oral administration of opioid tablets, the most prevalent route of opioid overdose and abuse.
This amendment #14 has an effective date of June 15,
2026 and extends the FDA’s acceptance date of a New Drug Application (“NDA”) for LTX-03 from June 30, 2026 to December 31,
2026 (“NDA Acceptance Date”) (“Amended Agreement”).
AD Pharma may terminate the Amended Agreement
at any time. Additionally, if the NDA for LTX-03 is not accepted by the FDA by the NDA Acceptance Date, AD Pharma may terminate the Amended
Agreement and take ownership of the intellectual property rights of LTX-03 from the Company. Should AD Pharma choose not to exercise this
option to terminate the Amended Agreement and the NDA for LTX-03 is subsequently accepted by the FDA, such option to terminate the Amended
Agreement expires.
The inclusion of a description of the Amended
Agreement with AD Pharma under Item 1.01 of this Current Report on Form 8-K shall not be deemed an acknowledgment that the Amended
Agreement is a material agreement not made, or deemed not to be made, in the ordinary course of our business.
Item 1.01 - Entry into a Material Definitive
Agreement.
On June 29, 2026, we received the executed
agreement to further amend the November 10, 2022 Amended, Consolidated and Restated Secured Promissory Note (the “Amended Note”)
with AD Pharma. This amendment #8 has an effective date of June 15, 2026 and changes the maturity date of the Amended Note from June 30,
2026 to December 31, 2026, at which time all principal and interest is due.
The inclusion of a description of the Amended
Note under Item 1.01 of this Current Report on Form 8-K shall not be deemed an acknowledgement that the Amended Note is a material
agreement not made, or deemed not to be made, in the ordinary course of our business.
Item 1.01 – Entry into a Material Definitive Agreement.
We previously announced on June 28, 2019,
we entered into a promissory note with John Schutte that consolidated existing promissory notes into a single note for $6.0 million bearing
interest at 7.5% (“$6.0 Million Note”). At that time, we also granted to Mr. Schutte conversion rights of the $6.0 Million
Note into Acura common stock at $0.16 per share, issued to him a warrant to purchase 10.0 million shares of the Company’s common
stock at a price of $0.01 per share having an expiration date of June 28, 2024 (“Warrant”) and granted a security interest
in all our assets (“Security Agreement”). With our consent, effective on June 28, 2019, Mr. Schutte assigned and
transferred to AD Pharma all of his right, title and interest in this $6.0 Million Loan, Security Agreement and Warrant. We previously
announced on June 9, 2021, we received notice of conversion from AD Pharma for the $6.0 Million Note and approximately $877 thousand
of accrued but unpaid interest on the $6.0 Million Note. The principal and interest on the $6.0 Million Note were converted into 42,984,375
shares of the Company’s common stock.
Effective June 15, 2026, in consideration
of further amending the November 10, 2022 Amended, Consolidated and Restated Secured Promissory Note (the “Note”) with
AD Pharma which changed the maturity date of the Note from June 30, 2026 to December 31, 2026, we amended the Warrant to change
the expiration date of the Warrant from June 30, 2026 to December 31, 2026.
The inclusion of a description of the Warrant
under Item 1.01 of this Current Report on Form 8-K shall not be deemed an acknowledgement that the Note is a material agreement not
made, or deemed not to be made, in the ordinary course of our business.
At June 15, 2026, AD Pharma directly owns
approximately 65% of the outstanding common stock of the Company. The ownership percentage of the Company held by AD Pharma does not include
their warrant to purchase 10.0 million shares of common stock of the Company. AD Pharma is an entity controlled by Mr. Schutte, of
which Mr. Schutte is the managing partner and investor. At June 15, 2026, Mr. Schutte directly owns approximately 13% of
the outstanding common stock of the Company.
Item 2.01 – Completion of Acquisition
or Disposition of Assets
The contents of all Items 1.01 are incorporated herein by reference.
Item 2.03 - Creation of a Direct Financial
Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant
