**Item 1.01. Entry Into a Material Definitive Agreement.**

As previously reported, on January 16, 2026, Allegro Merger Corp., a Delaware corporation ("<u>Allegro</u>"), entered into an Agreement and Plan of Merger ("<u>Merger Agreement</u>") with SeeQC, Inc., a Delaware corporation (the "<u>Company</u>" or "<u>SeeQC</u>"), and SEEQC Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of SeeQC ("<u>Merger Sub</u>"). Pursuant to the Merger Agreement, Allegro will merge with and into Merger Sub, with Allegro surviving the merger (the "<u>Merger</u>"). As a result of the Merger, Allegro will become a direct, wholly-owned subsidiary of SeeQC and the security holders of Allegro will become security holders of SeeQC. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in Allegro's Current Report on Form 8-K filed with the Securities and Exchange Commission on January 16, 2026.

On April 22, 2026, Allegro and SeeQC entered into agreements (the "<u>Allegro Warrant Support Agreements</u>") with the holders of approximately 48.5% of the outstanding warrants of Allegro (the "<u>Supporting Warrant Holders</u>"). Pursuant to the Allegro Warrant Support Agreements, the Supporting Warrant Holders agreed to vote or cause to be voted all Allegro Warrants beneficially held by them (i) in favor of all proposals necessary to effectuate an amendment to the Allegro Warrants whereby such warrants will, on the Closing, automatically convert into the right to receive one-tenth of one share of SeeQC Common Stock (the "<u>Warrant Amendment</u>"); and (ii) against (x) any proposal or offer from any other person (other than SeeQC or its affiliates) with respect to an alternative amendment to the Allegro Warrants; and (y) any action, proposal, transaction, or agreement that could reasonably be expected to materially impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Warrant Amendment or the fulfillment of Allegro's obligations under the Warrant Amendment. Pursuant to the agreement governing the Allegro Warrants, approval by 65% of the outstanding Allegro Warrants is required to effectuate the Warrant Amendment.

 

*The foregoing summary of the Allegro Warrant Support Agreements is qualified in its entirety by reference to the text of such agreements, the form of which is attached as Exhibit 10.1 and is incorporated herein by reference.*

**Additional Information and Where To Find It**

In connection with the Merger, SeeQC intends to file with the SEC a registration statement on Form S-4, which will include a prospectus with respect to the securities to be issued in connection with the Merger (the "prospectus"), as well as other relevant documents concerning the transactions. The registration statement is also expected to include an information statement with respect to the approval of the transactions by the Allegro stockholders. After the registration statement is declared effective by the SEC, the prospectus and information statement included in the registration statement will be mailed to Allegro shareholders. INVESTORS AND SHAREHOLDERS OF ALLEGRO ARE URGED TO READ CAREFULLY AND IN THEIR ENTIRETY THE PROSPECTUS AND INFORMATION STATEMENT WHEN THEY BECOME AVAILABLE, AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC, AS WELL AS ANY AMENDMENTS OR SUPPLEMENTS TO THOSE DOCUMENTS BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION. Investors and shareholders will be able to obtain a free copy of the prospectus and information statement, as well as other filings containing information about SeeQC and Allegro, without charge, once available, at the SEC's website, http://www.sec.gov.

**No Offer or Solicitation** 

This report shall not constitute a solicitation of a proxy, consent, or authorization with respect to any securities or in respect of the Transactions. This report shall also not constitute an offer to subscribe for, buy or sell, the solicitation of an offer to subscribe for, buy or sell or an invitation to subscribe for, buy or sell any securities or the solicitation of any vote or approval in any jurisdiction pursuant to or in connection with the Transactions or otherwise, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in contravention of applicable law. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act, and otherwise in accordance with applicable law.

**Cautionary Statement Regarding Forward-Looking Statements** 

Certain statements herein and the documents incorporated herein by reference may constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act, and Rule 175 promulgated thereunder, and Section 21E of the Securities Exchange Act of 1934, as amended, and Rule 3b-6 promulgated thereunder, which statements involve inherent risks and uncertainties. Examples of forward-looking statements include, but are not limited to, statements with respect to the expectations, hopes, beliefs, intentions, plans, prospects, financial results of strategies regarding Allegro, SeeQC, the Transactions and statements regarding the anticipated benefits and timing of the completion of the Transactions, the upside potential and opportunity for investors, regulatory conditions, future financial condition and performance and expected financial impacts of the Transactions, the satisfaction of closing conditions to the Merger and the PIPE, and SeeQC's and Allegro's expectations, intentions, strategies, assumptions or beliefs about future events, results of operations or performance that do not solely relate to historical or current facts. These forward-looking statements generally are identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "strategy," "future," "opportunity," "potential," "plan," "may," "should," "will," "would," "will be," "will continue," "will likely result," and similar expressions. Forward-looking statements are based on assumptions as of the time they are made and are subject to risks, uncertainties and other factors that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results expressed or implied by such forward-looking statements. Such risks, uncertainties and assumptions, include, but are not limited to:

● the risk that the Transactions may not be completed in a timely manner or at all;

● the failure by the parties to satisfy the conditions to the consummation of the PIPE and the Merger, including shareholder approvals;

● the failure to realize the anticipated benefits of the Transactions;

● the outcome of any potential legal proceedings that may be instituted against SeeQC, Allegro, or others following announcement of the Transactions;

● the failure of SeeQC to obtain or maintain the listing of its securities on any stock exchange on which the securities of SeeQC will be listed after closing of the Merger;

● costs related to the Transactions and as a result of SeeQC becoming a public company;

● technological developments and changes in business, market, financial, political and regulatory conditions;

● the risk that after consummation of the Merger, SeeQC could experience difficulties managing its growth and expanding operations;

● challenges in implementing SeeQC's business plan due to operational challenges, significant competition, regulatory changes or other factors;

● those risk factors discussed in documents of SeeQC and/or Allegro filed, or to be filed, with the SEC.

The foregoing list of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the "Risk Factors" section of Allegro's Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and the prospectus that will be filed by SeeQC, and other documents filed or to be filed by SeeQC and Allegro from time to time with the SEC. These filings do or will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. There may be additional risks that none of SeeQC or Allegro presently know or currently believe are immaterial that could also cause actual results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and none of the parties or any of their representatives assumes any obligation, or intends, to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of the parties or any of their representatives gives any assurance that SeeQC or Allegro will achieve its expectations.

Each Voting Party hereby (i) waives, and agrees not to assert or perfect, any rights of appraisal or rights to dissent from the Warrant Amendment that Voting Party may have by virtue of ownership of the Voting Securities and (ii) agrees not to commence or participate in any claim, derivative or otherwise, against Allegro relating to the negotiation, execution or delivery of this Agreement or the Warrant Amendment, including any claim (A) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Warrant Amendment or (B) alleging a breach of any fiduciary duty of the board of directors of Allegro in connection with this Agreement or the Warrant Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Redemption Rights</u>. Each Voting Party agrees not to exercise any right to redeem its Voting Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Acquisition of Additional Warrants</u>. In the event that, during the term of this Agreement, (a) any Voting Securities are issued to a Voting Party pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of Voting Securities or otherwise, (b) a Voting Party purchases or otherwise acquires beneficial ownership of any Voting Securities or (c) a Voting Party acquires the right to vote or share in the voting of any Voting Securities (collectively the "<u>New Securities</u>"), then such New Securities acquired or purchased by such Voting Party shall be subject to the terms of this Agreement to the same extent as if they constituted the Voting Securities owned by such Voting Party as of the date hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Termination</u>. This Agreement shall automatically terminate upon the earliest to occur of (i) the effective time of the Warrant Amendment, (ii) the date on which the Merger Agreement is terminated in accordance with its terms, and (iii) the effective date of a written agreement executed and delivered by the Company and each Voting Party terminating this Agreement. Upon termination of this Agreement, no party shall have any further obligations or liabilities under this Agreement; <u>provided</u>, that nothing in this <u>Section 9</u> shall relieve any party of liability for any willful breach of this Agreement occurring prior to termination. Notwithstanding the foregoing, Sections 6, 10, 11, 12, 13 and this Section 9 shall survive termination of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Specific Enforcement</u>. Each of the parties hereto agrees that irreparable harm for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that it does not fully and timely perform its obligations under or in connection with this Agreement (including failing to take such actions as are required of it hereunder) in accordance with its terms. Each of the parties hereto acknowledges and agrees that (i) the other parties will be entitled to an injunction, specific performance or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, without proof of damages and without posting a bond, this being in addition to any other remedy to which such other parties are entitled under this Agreement and (ii) the right to obtain an injunction, specific performance, or other equitable relief is an integral part of this Agreement and without that right, none of the parties would have entered into this Agreement. Each party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other parties have an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties acknowledge and agree that any party seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this <u>Section 10</u> shall not be required to provide any bond or other security in connection with any such injunction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Entire Agreement; Nonreliance; Amendments; Waivers</u>. This Agreement, together with the Merger Agreement, and any other documents, instruments and certificates explicitly referred to herein, constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes any and all prior discussions, negotiations, proposals, undertakings, understandings and agreements, whether written or oral, with respect thereto. No party has relied on any representations or commitments other than those explicitly contained in this Agreement and there are no restrictions, promises, representations, warranties, covenants or undertakings, other than those expressly provided for herein and therein. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or, in the case of a waiver, by the party against whom the waiver is to be effective. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. <u>Notices</u>. Any notice, request, demand, claim or other communication required or permitted to be delivered, given or otherwise provided under this Agreement must be in writing and must be delivered personally, delivered by nationally recognized overnight courier service, sent by certified or registered mail, postage prepaid, or sent by electronic mail to the applicable email address specified below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Governing Law*. This Agreement, the rights of the parties hereunder and any Legal Proceeding arising out of this Agreement, arising in whole or in part under or in connection herewith, will be governed by and construed and enforced in accordance with the internal laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule that would cause the application of the Applicable Laws of any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Jurisdiction*. Any Legal Proceeding arising out of this Agreement may be brought in any state or federal court sitting in the State of Delaware, but in no other court. Each of the parties to this Agreement, by its execution hereof, (i) hereby irrevocably submits to the jurisdiction of any state or federal court sitting in the State of Delaware, for the purpose of any Legal Proceeding relating to or arising in whole or in part under or in connection with this Agreement (whether in law or in equity, whether in contract or in tort, by statute or otherwise), (ii) hereby waives to the extent not prohibited by Applicable Law, and agrees not to assert, by way of motion, as a defense or otherwise, in any such Legal Proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that any such Legal Proceeding brought in one of the above-named courts should be dismissed on grounds of forum non conveniens, should be transferred or removed to any court other than one of the above-named courts, or should be stayed by reason of the pendency of some other Legal Proceeding in any other court other than one of the above-named courts or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such court and (iii) hereby agrees not to commence any such Legal Proceeding other than before one of the above-named courts. Notwithstanding the previous sentence a party may commence any Legal Proceeding in a court other than the above-named courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Service of Process*. Each of the parties to this Agreement hereby (i) consents to service of process in any Legal Proceeding among any of the parties hereto relating to or arising in whole or in part under or in connection with this Agreement (whether in law or in equity, whether in contract or in tort, by statute or otherwise) in any manner permitted by Applicable Law, (ii) agrees that service of process made in accordance with clause (i) or made by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to <u>Section 13</u>, will constitute good and valid service of process in any such Legal Proceeding and (iii) waives and agrees not to assert (by way of motion, as a defense, or otherwise) in any such Legal Proceeding, any claim that service of process made in accordance with clause (i) or (ii) does not constitute good and valid service of process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) *Waiver of Jury Trial*. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LEGAL REQUIREMENTS THAT CANNOT BE WAIVED, EACH OF THE PARTIES HEREBY WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR ANY OF THE TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE THEIR RESPECTIVE RIGHTS TO TRIAL BY JURY IN ANY ACTION WHATSOEVER BETWEEN OR AMONG THEM RELATING TO THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR ANY OF THE TRANSACTIONS AND THAT SUCH ACTIONS WILL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY. EACH PARTY ACKNOWLEDGES THAT NO PARTY HAS AGREED NOT TO ENFORCE THIS WAIVER OF THE RIGHT TO TRIAL BY JURY.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) *Severability*. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction will not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. In the event that any provision hereof would, under Applicable Law, be invalid or unenforceable in any respect, each party hereto intends that such provision will be construed by modifying or limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, Applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) *Counterparts; Electronic Delivery*. This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute but one and the same instrument. This Agreement will become effective when duly executed and delivered by each party hereto. Counterpart signature pages to this Agreement may be delivered by facsimile or electronic delivery (i.e., by email of a .PDF signature page or by DocuSign or similar electronic means) and each such counterpart signature page will constitute an original for all purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) *Titles and Headings*. The titles and captions in this Agreement are for reference purposes only, and shall not in any way define, limit, extend or describe the scope of this Agreement or otherwise affect the meaning or interpretation of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) *Succession and Assignment; No Third Party Beneficiaries*. This Agreement will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, each of which such successors and permitted assigns will be deemed to be a party hereto for all purposes hereof. No party may assign, delegate or otherwise transfer, including by operation of law or by merger, either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties hereto, and any attempt to do so will be null and void ab initio. Except as expressly provided herein, this Agreement is for the sole benefit of the parties hereto and their successors and permitted assignees and nothing herein expressed or implied will give or be construed to give any Person, other than the parties hereto and such successors and permitted assignees, any other right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) *No Ownership Interests*. Except as provided in this Agreement, nothing contained in this Agreement shall be deemed to vest in the Company or Allegro any direct or indirect ownership or incidence of ownership of or with respect to any Voting Securities. Except as provided in this Agreement, all rights, ownership and economic benefits relating to the Voting Securities shall remain vested in and belong to the Voting Parties. Nothing in this Agreement shall be interpreted as creating or forming a "group" with any other Person for purposes of Rule 13d-5(b)(1) of the Exchange Act or any other similar provision of Applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) *Expenses*. All fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees, costs and expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) *Further Assurances*.
