~~Forward-Looking~~Item ~~Statements~~1.01 Entry into a Material Definitive Agreement

~~This~~Public Current Report on Form 8-K contains certain forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact included in this Current Report on Form 8-K, including statements regarding the Company’s future financial condition, results of operations, business operations and business prospects, are forward-looking statements. These statements are identified by the use of the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “may,” “continue,” “predict,” “potential,” “project” and similar expressions that are intended to identify forward-looking statements. All forward-looking statements are subject to important factors, risks, uncertainties, and assumptions, including industry and economic conditions that could cause actual results to differ materially from those described in the forward-looking statements. Such factors, risks, uncertainties and assumptions include, but are not limited to, the Company’s ability to successfully achieve its strategic initiatives, including its expectation that it will be able to secure additional miners; unexpected costs, charges or expenses resulting from the Acquisition; potential adverse reactions or changes to business relationships resulting from the completion of the Acquisition; risks related to the inability of the Company to successfully operate as a combined business; risks associated with the possible failure to realize certain anticipated benefits of the Acquisition, including with respect to future financial and operating results; competition in the Company’s markets; risks associated with the Company’s investment strategy, including digital asset market volatility, cybersecurity and custody of digital assets, potential changes in laws or accounting standards relating to digital assets and regulatory developments affecting digital assets; and volatility of the Company’s stock price. Forward-looking statements also are affected by the risk factors described in the Company’s filings with the U.S. Securities and Exchange Commission, including in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K. The risks and uncertainties that the Company has described are not the only ones the Company faces. Additional risks and uncertainties not presently known to the Company or that the Company currently deems immaterial may also affect the Company’s operations. All forward-looking statements speak only as of the date of this Current Report on Form 8-K. You should not place undue reliance on these forward-looking statements. Although the Company believes that its plans, objectives, expectations and intentions reflected in or suggested by the forward-looking statements are reasonable, it can give no assurances that these plans, objectives, expectations or intentions will be achieved. Forward-looking statements involve significant risks and uncertainties (some of which are beyond the Company’s control) and assumptions that could cause actual results to differ materially from historical experience. Actual results may differ materially from those in the forward-looking statements and the trading price for the Company’s common stock may fluctuate significantly Except as required by law, the Company undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events.Offering

On March 26, 2026, Datacentrex, Inc. (the “Company”) entered into a placement agency agreement (the “Placement Agency Agreement”) with Dominari Securities LLC (the “Placement Agent”), pursuant to which the Company agreed to issue and sell directly to investors (the “Investors”), in a best efforts offering (the “Offering”), an aggregate of (i) 4,510,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 (the “Common Stock”), at $2.00 per share and (ii) pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to an aggregate of 5,575,000 shares (the “Pre-Funded Warrant Shares” and together with the Shares and the Pre-Funded Warrants, the “Securities”) of the Company’s Common Stock at $1.99 per Pre-Funded Warrant.

Each Pre-Funded Warrant is exercisable until exercised in full at an exercise price of $0.01 per share. The Company is prohibited from effecting an exercise of the Pre-Funded Warrants to the extent that, as a result of such exercise, the holder together with the holder’s affiliates, would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of the Pre-Funded Warrant, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%.

Pursuant to the terms of the Placement Agency Agreement, the Company has agreed, for a period of six months from the Closing Date (as defined herein), not to issue (or enter into any agreement to issue) any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company, or file or caused to be filed any registration statement relating to the offering of any shares of capital stock of the Company or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company, subject to certain exceptions. In addition, each of the Company’s officers, and directors of the Company’s Common Stock have entered into lock-up agreements with the Company pursuant to which each of them has agreed not to, for a period of six months from the Closing Date, offer, sell, transfer or otherwise dispose of the Company’s securities, subject to certain exceptions. The Company’s Chief Financial Officer, Robert Steele, has entered into a separate “lock-up” agreement containing the restrictions described above, provided that such lock-up period will end on the earlier of (x) six months after the Closing Date and (y) the date on which he ceases to be an “Affiliate” of the Company, as such term is defined in Rule 405 of the Securities Act of 1933, as amended.

The Securities were offered and sold by the Company pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-286951) (as amended, the “Registration Statement”), including a base prospectus, initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 2, 2025, as amended and declared effective on May 30, 2025.

The closing of the Offering occurred on March 31, 2026 (the “Closing Date”). The gross proceeds to the Company from the Offering were approximately $20.2 million, before deducting Placement Agent fees and expenses and estimated Offering expenses payable by the Company. The Company intends to use the net proceeds received from the Offering for working capital and general corporate purposes.

Pursuant to the Placement Agency Agreement, the Company paid the Placement Agent a cash fee equal to 8% of the aggregate purchase price paid by the Investors in the Offering and a cash fee equal to 1% of the aggregate purchase price paid by the Investors in the Offering for non-accountable expenses. The Company also reimbursed the Placement Agent for all reasonable and out-of-pocket expenses incurred in connection with the Placement Agent’s engagement, including reasonable fees and expenses of the Placement Agent’s legal counsel in the amount of $250,000. Furthermore, the Company issued the Placement Agent a warrant (the “Placement Agent Warrant”) to purchase up to 806,800 shares of the Company’s Common Stock at an exercise price of $2.00 per share. The Placement Agent Warrant will be exercisable 180 days after the date of the Placement Agency Agreement and has a term of exercise equal to five years from the date of issuance.

The Placement Agency Agreement contains customary representations and warranties, agreements and obligations, conditions to closing and termination provisions. The foregoing descriptions of terms and conditions of the Placement Agency Agreement, the Pre-Funded Warrant and the Placement Agent Warrant do not purport to be complete and are qualified in their entirety by the full text of the Placement Agency Agreement, the form of Pre-Funded Warrant and the form of Placement Agent Warrant, copies of which are attached as Exhibits 1.1, 10.1 and 10.2, respectively, to this Current Report on Form 8-K and are incorporated by reference herein.
