Item 1.01 Entry Into a Material Definitive Agreement.

Agreement and Plan of Merger

On December 10, 2025, Enova International, Inc. ("Enova"), a Delaware corporation, and Grasshopper Bancorp, Inc. ("Grasshopper"), a Delaware corporation and the parent holding company of Grasshopper Bank N.A. ("Grasshopper Bank"), a national bank and wholly-owned subsidiary of Grasshopper, entered into an Agreement and Plan of Merger (the "Merger Agreement"). Under the terms and subject to the conditions of the Merger Agreement, among other things, (1) Grasshopper will merge with and into Enova, with Enova continuing as the surviving corporation (the "Merger"), and (2) immediately following the Merger, an interim national bank and wholly owned subsidiary of Enova to be formed following the date hereof will merge with and into Grasshopper Bank, with Grasshopper Bank continuing as the surviving bank (the "Bank Merger" and, together with the Merger, the "Mergers"), each as more fully described in the Merger Agreement. The Merger Agreement was unanimously approved by the Board of Directors of each of Enova and Grasshopper.

Merger Consideration

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each share of common stock, par value $0.01 per share, of Grasshopper ("Grasshopper Common Stock"), excluding certain specified shares owned by Enova or Grasshopper and shares held by stockholders who properly exercise appraisal rights, that is issued and outstanding immediately prior to the Effective Time, will be converted, at the election of the applicable stockholder and subject to procedures applicable to oversubscription and undersubscription for cash consideration as described in the Merger Agreement, into the right to receive either (i) 0.07637 of a share of common stock, par value $0.00001 per share, of Enova ("Enova Common Stock"), with cash paid in lieu of fractional shares (the "Stock Consideration"), or (ii) $9.69 (the "Cash Consideration" and, together with the Stock Consideration, the "Per Share Merger Consideration"), which Per Share Merger Consideration is subject to adjustment pursuant to the terms of the Merger Agreement such that the total consideration for all outstanding shares of Grasshopper Common Stock remains no higher than approximately $350 million in the aggregate (the "Merger Consideration"). The Merger Agreement provides that the aggregate amount of Cash Consideration will equal 50% of the Merger Consideration.

At the Effective Time, each stock option in respect of Grasshopper Common Stock ("Grasshopper Stock Option") will be fully vested then cancelled and converted into the right to receive from Enova a cash payment (less any required tax withholding) equal to the product, rounded up to the nearest cent, of (a) the number of shares of Grasshopper Common Stock subject to such Grasshopper Stock Option immediately prior to the Effective Time, multiplied by (b) the difference, if positive, between the Cash Consideration and the exercise price of the Grasshopper Stock Option. Any Grasshopper Stock Option with an exercise price that equals or exceeds the Cash Consideration will be canceled with no consideration being paid to the optionholder.

At the Effective Time, each warrant in respect of Grasshopper Common Stock ("Grasshopper Warrant"), whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time will be canceled and the holder thereof will have no further rights with respect to such Grasshopper Warrant, unless the holder of such Grasshopper Warrant executes a warrant cancelation agreement prior to the Effective Time, in which case, such Grasshopper Warrant subject to an executed warrant cancelation agreement will instead be canceled and converted into the right to receive from Enova a cash payment (less any required withholding) equal to a pro rata amount of the aggregate amount payable by Enova in respect of the Grasshopper Warrants of $2,500,000.

Corporate Governance

The directors and officers of Enova in office immediately prior to the Effective Time will serve as the directors of Enova as the surviving corporation of the Merger from and after the Effective Time in accordance with the certificate of incorporation and bylaws of Enova. Michael Butler, Grasshopper's CEO, will serve as President of the surviving bank, reporting to Steve Cunningham, who will be appointed CEO of the surviving bank.

Representations and Warranties; Covenants

The Merger Agreement contains customary representations and warranties from both Enova and Grasshopper, and each party has agreed to customary covenants, including, among others, covenants relating to (a) the conduct of each party's business during the interim period between the execution of the Merger Agreement and the Effective Time, (b) Grasshopper's obligation to call a meeting of its stockholders for purposes of obtaining approval of the Merger Agreement and the transactions contemplated thereby and to recommend that its stockholders approve the same, and (c) non-solicitation obligations of Grasshopper relating to alternative acquisition proposals or entering into negotiations, inquiries or discussions or providing information in connection with, any alternative acquisition.

Each of the parties has agreed to use its reasonable best efforts to obtain as soon as reasonably practicable all consents required to be obtained from any third parties and regulatory authorities that are necessary or advisable to consummate the transactions contemplated by the Merger Agreement (including the Mergers). Notwithstanding such general obligation to obtain such consents of regulatory authorities, Enova and its subsidiaries are not required, and Grasshopper and its subsidiaries are not permitted (without Enova's prior written consent in its sole discretion), to take any action, or commit to take any action, or to accept any restriction, commitment or condition, involving itself or its subsidiaries, which would reasonably be expected to be materially financially burdensome to the business, operations, financial condition or results of operations of Enova and its subsidiaries, taken as a whole after giving effect to the Mergers and certain other transactions contemplated by the Merger Agreement (a "Burdensome Condition").

Closing Conditions

The completion of the Merger is subject to customary conditions, including, among others, (a) receipt of the approval of the stockholders of Grasshopper; (b) receipt of all required regulatory approvals (or waivers), including from the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency; (c) absence of any law or order (whether temporary, preliminary or permanent) by any court or regulatory authority of competent jurisdiction prohibiting, restricting or making illegal the consummation of the transactions contemplated by the Merger Agreement (including the Mergers); (d) effectiveness of the registration statement, including the proxy statement/prospectus, relating to the approval of the Merger by the stockholders of Grasshopper and the issuance of Enova Common Stock in the Merger; (e) approval for listing on the New York Stock Exchange of the shares of Enova Common Stock to be issued in the Merger; (f) each party's receipt of an opinion from Covington & Burling LLP to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; and (g) the absence of a material adverse effect on the other party since the date of the Merger Agreement. Each party's obligation to complete the Merger is also subject to certain additional customary conditions, including (i) subject to certain exceptions, the accuracy of the representations and warranties of the other party, subject to customary bring-down materiality standards; and (ii) performance in all material respects by the other party of its obligations under the Merger Agreement.

Enova's obligation to consummate the Merger is also subject to customary conditions, including, among others: (a) receipt of required regulatory approvals without the imposition of a Burdensome Condition; (b) that holders of not more than 2% of the outstanding shares of Grasshopper Common Stock have properly demanded appraisal rights for such shares pursuant to Delaware law; (c) Grasshopper's satisfaction of certain regulatory capital requirements, including being "well capitalized" pursuant to applicable law and having a tier 1 leverage ratio of no lower than 8%; and (d) termination of certain contracts of Grasshopper and of certain Grasshopper Warrants.

Termination

The Merger Agreement provides certain termination rights for both Enova and Grasshopper and further provides that a termination fee of $5,000,000 will be payable by Enova, upon termination of the Merger Agreement under certain circumstances. The Merger Agreement also provides that, subject to certain conditions, either party can terminate the Merger Agreement after the 360th day following the execution thereof unless Enova and Grasshopper agree, and Enova pays Grasshopper $5,000,000, to extend the date at which either party can terminate the Merger Agreement to the 450th day following the execution thereof.

Additional Information

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Exhibit 2.1 hereto and is incorporated herein by reference.

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement (other than, in the case of certain covenants, third party beneficiaries expressly identified therein), may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between Enova and Grasshopper instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (a) will not survive consummation of the Merger, unless otherwise specified therein, and (b) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties' public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding Enova or Grasshopper, their respective affiliates or their respective businesses.

The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding Enova, Grasshopper, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the registration statement on Form S-4 to be filed by Enova (the "registration statement") under the Securities Act of 1933, as amended (the "Securities Act") that will include a proxy statement of Grasshopper and a prospectus of Enova (the "proxy statement/prospectus"), as well as in the Forms 10-K, Forms 10-Q and other filings that Enova makes with the Securities and Exchange Commission ("SEC").

Voting Agreements

In addition, the Voting Agreements provide that such stockholders will not transfer (i) any of their shares of Grasshopper Common Stock, subject to certain exceptions, prior to the earlier to occur of the Effective Time, the termination of the Merger Agreement and the termination of the Voting Agreement and (ii) any shares of Enova common stock received in the Merger during the period commencing as of the Effective Time until the 270th day following the date of the consummation of the Merger, provided that this restriction will cease to apply with respect to 33% of such shares as of the 90th day following the date of the consummation of the Merger, and with respect to 66% of such shares as of the 180th day following the date of the consummation of the Merger.

The stockholders of Grasshopper that are parties to Voting Agreements own in the aggregate approximately 56.3% of the outstanding shares of Grasshopper Common Stock with voting rights as of December 8, 2025.
