Overview

Datacentrex, Inc. is a digital infrastructure and capital deployment company that owns and operates Scrypt compute assets and evaluates strategic transactions across asset-backed operating businesses. Our current operating platform is centered on owned and operated Scrypt-based proof-of-work compute deployed through third-party colocation facilities. We monetize this compute primarily through hashrate marketplace mechanisms and manage a treasury of digital assets and cash in a manner intended to preserve capital and support opportunistic, accretive deployment.

Our Scrypt compute operations utilize specialized application-specific integrated circuit (“ASIC”) hardware to contribute hashrate to the Litecoin blockchain. Through merged-mining architecture, that same hashrate can simultaneously secure and validate additional Scrypt-based networks, including Dogecoin and other auxiliary Scrypt chains, without incremental energy consumption. This merged-mining attribute allows a single deployment of compute and power to produce economic exposure to multiple networks, subject to protocol rules and monetization mechanics.

As of the consummation of the transaction between Thumzup Media Corporation and Dogehash Technologies, Inc., the Company operates more than 3,100 Scrypt ASIC miners deployed across multiple geographically diversified colocation facilities.

Our results are primarily driven by (i) realized revenue rate per unit of hashrate deployed, (ii) power cost and curtailment exposure at the facility level, (iii) uptime and operational execution, (iv) availability and replacement cycle dynamics for Scrypt ASIC supply, and (v) treasury and capital allocation decisions, including decisions regarding holding, converting, or deploying digital assets and cash.

We are not a protocol developer. We do not control any blockchain network and do not generate revenues from maintaining or updating any open-source network protocol. Our results depend on our ability to procure and operate compute infrastructure economically and to monetize that compute in a manner that produces attractive risk-adjusted returns.

Recent Developments

Doge Acquisition

On August 18, 2025, Datacentrex entered into an Agreement and Plan of Merger (the “Merger Agreement”) with TZUP Merger Sub, Inc., a wholly-owned subsidiary of Datacentrex (“Merger Sub”), and Doge, a Nevada corporation, pursuant to which the Company agreed to acquire Doge (the “Acquisition”).

On December 15, 2025, Merger Sub and Doge filed Articles of Merger with the Nevada Secretary of State pursuant to which, effective as of December 15, 2025, Merger Sub merged with and into Doge with Doge surviving as a wholly-owned subsidiary of the Company. Pursuant to the terms of the Merger Agreement, the Company issued an aggregate of 13,835,188 shares of the Company’s Common Stock, and 16,239.812 shares of Series D Convertible Preferred convertible into an aggregate of 16,239,812 shares of Common Stock to the stockholders of Doge in exchange for 100% of the outstanding capital stock of Doge.

For a summary of the Acquisition, see “Issuance of Common Stock and Series D Convertible Preferred Stock” beginning on page 9 of this prospectus.

Name Change

On December 15, 2025, the Company filed a Certificate of Amendment to its Amended and Restated Articles of Incorporation with the Secretary of State of the State of Nevada to change its name to Datacentrex, Inc. from Thumzup Media Corporation.

Corporate Information

The Company was incorporated under the laws of the State of Nevada on October 27, 2020, under the name Thumzup Media Corporation and changed its name to Datacentrex, Inc., effective December 15, 2025, in connection with the Acquisition.

The Company’s operations are principally operated remotely at various data centers throughout the United States. The Company’s principal address is 470 W 200 N STE 18, Salt Lake City, UT 84103 and its telephone number is (800) 403-6150. The Company’s website address is www.datacentrex.com. The information provided on the Company’s website is not part of this prospectus and is not incorporated by reference into this prospectus.

Implications of Being an Emerging Growth Company

As a company with less than $1.235 billion in revenues during our last fiscal year, we qualify as an emerging growth company as defined in the Jumpstart Our Business Startups Act (“JOBS Act”) enacted in 2012. As an emerging growth company, we expect to take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:

	●	being permitted to present only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations”;

	●	not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended (“Sarbanes-Oxley Act”);

	●	reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and

	●	exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We may use these provisions until the last day of our fiscal year following the fifth anniversary of the completion of our initial public offering. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenues exceed $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period.

The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. As an emerging growth company, we intend to take advantage of an extended transition period for complying with new or revised accounting standards as permitted by The JOBS Act.

To the extent that we continue to qualify as a “smaller reporting company,” as such term is defined in Rule 12b-2 under the Securities Exchange Act of 1934, after we cease to qualify as an emerging growth company, certain of the exemptions available to us as an emerging growth company may continue to be available to us as a smaller reporting company, including: (i) not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes Oxley Act; (ii) scaled executive compensation disclosures; and (iii) the requirement to provide only two years of audited financial statements, instead of three years.

RISK FACTORS

Investing in our securities involves substantial risks. Please carefully consider the risk factors described below together with the risk factors described in our most recent Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 11, 2025, as amended April 30, 2025 and October 30, 2025 on Form 10-K/As, any subsequent updates in our Quarterly Reports on Form 10-Q, our Definitive Proxy Statement on Schedule 14A 14A filed with the SEC on October 30, 2025, and in any other filings we make with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), incorporated by reference herein, and the matters discussed under “Disclosure Regarding Forward-Looking Statements” below, before making an investment decision. Additional risk factors may be included in any prospectus supplements relating to securities described in this prospectus. The occurrence of any of those risks could materially and adversely affect our business, prospects, financial condition, results of operations or cash flow. Other risks and uncertainties that we do not now consider to be material or of which we are not now aware may become important factors that affect us in the future and could result in a complete loss of your investment.

A sale of a substantial number of shares of Common Stock by our stockholders may cause the price of our Common Stock to decline.

If our stockholders sell, or the market perceives that our stockholders intend to sell for various reasons, substantial amounts of our Common Stock in the public market, the price of our Common Stock may decline. Additionally, such conditions may make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate.

The price of our Common Stock may fluctuate substantially.

You should consider an investment in our Common Stock to be risky, and you should invest in our Common Stock only if you can withstand a significant loss and wide fluctuations in the market value of your investment. Some factors that may cause the market price of our Common Stock to fluctuate, in addition to the other risks mentioned in this “Risk Factors” section are:

	●	the results of operating and financial performance and prospects of other companies in the same industry;

	●	strategic actions by the Company or its competitors, such as acquisitions or restructurings;

	●	announcements of innovations, increased service capabilities, new or terminated customers or new, amended or terminated contracts by competitors;

	●	the public’s reaction to Company press releases, other public announcements, and filings with the Securities and Exchange Commission;

	●	lack of securities analyst coverage or speculation in the press or investment community about the Company or market opportunities in the social media marketing industry;

	●	changes in government policies in the United States and, as the Company’s international business increases, in other foreign countries;

	●	market and industry perception of the Company’s success, or lack thereof, in pursuing its growth strategy;

	●	changes in accounting standards, policies, guidance, interpretations or principles;

	●	any lawsuit involving the Company, its services or its products;

	●	arrival and departure of key personnel;

	●	sales of Common Stock by the Company, its investors or members of its management team; and

	●	changes in general market, economic and political conditions in the United States and global economies or financial markets, including those resulting from natural or man-made disasters.

In addition, if the market for stocks in our industry or industries related to our industry, or the stock market in general, experiences a loss of investor confidence, the trading price of our Common Stock could decline for reasons unrelated to our business, financial condition and results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management.

We will not receive any proceeds from the sale of the shares of Common Stock by the Selling Stockholders covered by this prospectus.

We are registering the shares of Common Stock that were, or may be, issued by us to the Selling Stockholders to permit the resale of these shares of Common Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the Selling Stockholders of the shares of Common Stock.

We do not intend to pay cash dividends on our shares of Common Stock so any returns will be limited to the value of our shares.

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the increase, if any, of our share price.

We are currently listed on The Nasdaq Capital Market. If we are unable to maintain listing of our securities on Nasdaq or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell their securities.

Although our Common Stock is currently listed on The Nasdaq Capital Market, we may not be able to continue to meet the exchange’s minimum listing requirements or those of any other national exchange. If we are unable to maintain listing on Nasdaq or if a liquid market for our Common Stock does not develop or is sustained, our Common Stock may remain thinly traded.

The Listing Rules of Nasdaq require listing issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, we should fail to maintain compliance with these listing standards and Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another national securities exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our stockholders:

	●	the liquidity of our Common Stock;

	●	the market price of our Common Stock;

	●	our ability to obtain financing for the continuation of our operations;

	●	the number of investors that will consider investing in our Common Stock;

	●	the number of market makers in our Common Stock;

●

the availability of information concerning the trading prices and volume of our Common Stock; and

●

the number of broker-dealers willing to execute trades in shares of our Common Stock.

DESCRIPTION OF SECURITIES

General

As of the date of this prospectus, our authorized capital stock consisted of 250,000,000 shares of Common Stock, $0.001 par value per share, and 25,000,000 shares of preferred stock, $0.001 par value per share. Our Board may establish the rights and preferences of the preferred stock from time to time. As of the date of this Prospectus, there were 32,238,955 shares of our Common Stock, 161,507.98 Shares of Series A Preferred Convertible Voting Stock, and 16,239.812 shares of Series D Convertible Preferred issued and outstanding. All outstanding shares of our Common Stock and preferred stock are fully paid and nonassessable.

The following is a summary description of the material terms and provisions of our Common Stock and Series D Convertible Preferred. For a more detailed description of these and our other securities, you should read the applicable provisions of Nevada law, our Articles of Incorporation, our Bylaws and the reports that we file with the SEC, which are incorporated herein by reference.

Common Stock

The following summarizes the rights of holders of our Common Stock:

●

a holder of Common Stock is entitled to one vote per share on all matters to be voted upon generally by the shareholders and are not entitled to cumulative voting for the election of directors;

●

subject to preferences that may apply to shares of Preferred Stock outstanding, the holders of Common Stock are entitled to receive lawful dividends as may be declared by our board of directors;

●

upon our liquidation, dissolution or winding up, the holders of shares of Common Stock are entitled to receive a pro rata portion of all our assets remaining for distribution after satisfaction of all our liabilities and the payment of any liquidation preference of any outstanding Preferred Stock;

●

there are no redemption or sinking fund provisions applicable to our Common Stock; and

●

there are no preemptive, subscription or conversion rights applicable to our Common Stock.

Series D Convertible Preferred Stock

Each share of Series D Preferred is convertible into 1,000 shares of Common Stock and contains a beneficial ownership limitation of 4.99% or 9.99% at the option of each holder. Holders of Series D Preferred are not entitled to vote. The Series D Preferred rank junior to the Company’s Series A Preferred Stock and is pari passu with the Common Stock. In the event of liquidation of the Company, the holders of Series D Preferred will share in the distribution of the Company’s net assets on an as-converted basis together with the Common Stock, subordinate only to the Series A Preferred Stock. The Series D Preferred conversion ratio is subject to equitable adjustment in the event of a stock split, reverse split and similar events.

Anti-Takeover Effects of Nevada Law and Our Articles of Incorporation and Bylaws

Some provisions of Nevada Revised Statutes, our articles of incorporation, and our bylaws contain provisions that could make the following transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise; or the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that shareholders may otherwise consider to be in their best interest or in our best interests, including transactions that provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Shareholder Meetings. Our bylaws provide that a special meeting of shareholders may be called only by our president, by all of the directors provided that there are no more than three directors, or if more than three, by any three directors, or by the holder of a majority of our capital stock.

Shareholder Action by Written Consent. Our bylaws allow for any action that may be taken at any annual or special meeting of the shareholders to be taken without a meeting and without prior notice, if a consent in writing, setting forth the action so taken, is signed by the holders of outstanding shares having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted.

Shareholders Not Entitled to Cumulative Voting. Our bylaws do not permit shareholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our Common Stock entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

Nevada Business Combination Statutes. The “business combination” provisions of Sections 78.411 to 78.444, inclusive, of the NRS, generally prohibit a Nevada corporation with at least 200 shareholders from engaging in various “combination” transactions with any interested shareholder for a period of two years after the date of the transaction in which the person became an interested shareholder, unless the transaction is approved by the board of directors prior to the date the interested shareholder obtained such status or the combination is approved by the board of directors and thereafter is approved at a meeting of the shareholders by the affirmative vote of shareholders representing at least 60% of the outstanding voting power held by disinterested shareholders, and extends beyond the expiration of the two-year period, unless:

	●	the was approved by the board of directors prior to the person becoming an interested shareholder or the transaction by which the person first became an interested shareholder was approved by the board of directors before the person became an interested shareholder or the combination is later approved by a majority of the voting power held by disinterested shareholders;

	●	the consideration to be paid by the interested shareholder is at least equal to the highest of: (a) the highest price per share paid by the interested shareholder within the two years immediately preceding the date of the announcement of the combination or in the transaction in which it became an interested shareholder, whichever is higher, (b) the market value per share of Common Stock on the date of announcement of the combination and the date the interested shareholder acquired the shares, whichever is higher, or (c) for holders of preferred stock, the highest liquidation value of the preferred stock, if it is higher.

A “combination” is generally defined to include mergers or consolidations or any sale, lease exchange, mortgage, pledge, transfer, or other disposition, in one transaction or a series of transactions, with an “interested shareholder” having: (a) an aggregate market value equal to 5% or more of the aggregate market value of the assets of the corporation, (b) an aggregate market value equal to 5% or more of the aggregate market value of all outstanding shares of the corporation, (c) 10% or more of the earning power or net income of the corporation, and (d) certain other transactions with an interested shareholder or an affiliate or associate of an interested shareholder. In general, an “interested shareholder” is a person who, together with affiliates and associates, owns (or within two years, did own) 10% or more of a corporation’s voting stock. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our shareholders the opportunity to sell their stock at a price above the prevailing market price.

Nevada Control Share Acquisition Statutes. The “control share” provisions of Sections 78.378 to 78.3793, inclusive, of the NRS apply to “issuing corporations” that are Nevada corporations with at least 200 shareholders, including at least 100 shareholders of record who are Nevada residents, and that conduct business directly or indirectly in Nevada. The control share statute prohibits an acquirer, under certain circumstances, from voting its shares of a target corporation’s stock after crossing certain ownership threshold percentages, unless the acquirer obtains approval of the target corporation’s disinterested shareholders. The statute specifies three thresholds: one-fifth or more but less than one-third, one-third but less than a majority, and a majority or more, of the outstanding voting power. Generally, once an acquirer crosses one of the above thresholds, those shares in an offer or acquisition and acquired within 90 days thereof become “control shares” and such control shares are deprived of the right to vote until disinterested shareholders restore the right. These provisions also provide that if control shares are accorded full voting rights and the acquiring person has acquired a majority or more of all voting power, all other shareholders who do not vote in favor of authorizing voting rights to the control shares are entitled to demand payment for the fair value of their shares in accordance with statutory procedures established for dissenters’ rights.

A corporation may elect to not be governed by, or “opt out” of, the control share provisions by making an election in its articles of incorporation or bylaws, provided that the opt-out election must be in place on the 10th day following the date an acquiring person has acquired a controlling interest, that is, crossing any of the three thresholds described above. We have not opted out of the control share statutes and will be subject to these statutes if we are an “issuing corporation” as defined in such statutes.

The effect of the Nevada control share statutes is that the acquiring person, and those acting in association with the acquiring person, will obtain only such voting rights in the control shares as are conferred by a resolution of the shareholders at an annual or special meeting. The Nevada control share law, if applicable, could have the effect of discouraging takeovers of us.

Amendment of Charter Provisions. The amendment of any of the above provisions would require approval by holders of at least a majority of the total voting power of all of our outstanding voting stock.

The provisions of Nevada law, our articles of incorporation, and our bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our Common Stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the composition of our board of directors and management. It is possible that these provisions could make it more difficult to accomplish transactions that shareholders may otherwise deem to be in their best interests.

The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the securities even if such securities would be disposed of by someone other than the holder. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any of the securities or with respect to any security that includes, relates to, or derives any significant part of its value from such securities.

SELLING STOCKHOLDERS

The shares of Common Stock being offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling Stockholders, upon conversion of the Series D Preferred Stock. For additional information regarding the issuances of those securities, see “Recent Developments – Doge Acquisition” above. We are registering the shares of Common Stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Except for the ownership of the shares of Common Stock, or as otherwise set forth herein the Selling Stockholders have not had any material relationship with us within the past three years.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of Common Stock by each of the Selling Stockholders. The second column lists the number of shares of Common Stock beneficially owned by each selling stockholder, based on its ownership of the shares of our securities, as of January 28, 2026, assuming conversion of the Series D Preferred Stock held by the Selling Stockholders on that date, without regard to any limitations on conversion.

The third column lists the shares of Common Stock being offered by this prospectus by the Selling Stockholders.

This prospectus generally covers the resale of the maximum number of shares of Common Stock issuable upon conversion of the Series D Preferred Stock, determined as if the outstanding Series D Preferred Stock were converted in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination. The fourth column assumes the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus. The Selling Stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

Each selling stockholder of the Registrable Securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on The Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling securities:

●

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●

ordinary trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

●

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

●

an exchange distribution in accordance with the rules of the applicable exchange;

●

privately negotiated transactions;

●

settlement of short sales;

●

in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

●

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

●

a combination of any such methods of sale; or

●

any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Registrable Securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the Registrable Securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the Registrable Securities may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

LEGAL MATTERS

The validity of the issuance of the securities offered hereby will be passed upon for us by Sheppard, Mullin, Richter & Hampton LLP, New York, NY. Additional legal matters may be passed upon for us or any underwriters, dealers, or agents by counsel that we will name in the applicable prospectus supplement.
