Ordinary Shares

**(b) Name of Issuer:**
West Enclave Merger Corp.

**(c) Address of Issuer's Principal Executive Offices:**
C. Calderon de la Barca 22, Ciudad de Mexico, O5, 11540

**Item 4. Purpose of Transaction**

On December 17, 2025, the Issuer issued an aggregate of 3,833,333 ordinary shares to Sponsor for an aggregate purchase price of $25,000. Third party designees of the sponsor purchased an aggregate of 147,500 of the private units Sponsor purchased, Jean-Michel Enriquez Dahlhaus, one of the Issuer's independent directors, purchased 5,000 of the private units Sponsor has purchased, and an entity affiliated with Hector Madero Rivero, another of the Issuer's independent directors, has purchased 20,000 of the private units Sponsor purchased, in each case at $10.00 per private unit. Sponsor transferred an aggregate of 1,380,000 ordinary shares of the Issuer (the "founder shares") on the closing of the initial public offering for an aggregate consideration of approximately $9,000, or approximately $0.0065 per founder share (including 40,000 founder shares to Mr. Enriquez and 160,000 founder shares to the entity affiliated with Mr. Madero). On May 1, 2026, the Issuer consummated its initial public offering ("IPO") and in connection with the consummation, Sponsor purchased an aggregate of 300,000 units for an aggregate purchase price of $3,000,000. On May 4, 2026, the underwriters of the Issuer, notified the Company of their exercise of the over-allotment option in full and purchased 1,500,000 additional units at $10.00 per unit upon the closing of the over-allotment option, generating gross proceeds of $15,000,000. The over-allotment option closed on May 6, 2026 simultaneously with a private placement of $412,500.

The reporting persons may acquire or dispose of additional securities or sell securities of the Issuer from time to time in the market or in private transactions, including as a result of ownership of the rights referred to above. However, reporting persons do not have any other agreements to acquire additional ordinary shares at this time. As Co-Chairmen and Co-Chief Executive Officers of the Issuer, Mr. Mahuad and Mr. Otero are involved in making material business decisions regarding the Issuer's policies and practices and may be involved in the consideration of various proposals considered by the Issuer's board of directors. Additionally, as the Issuer's business plan is to enter into a business combination, Mr. Mahuad and Mr. Otero, as Co-Chairmen and Co-Chief Executive Officers of the Issuer, are actively involved in pursuing a suitable target for the Issuer's business combination and will be actively involved in effecting any such business combination if the Issuer's business plan is successful, which may also result in a change in the Issuer's board of directors, corporate structure or charter.

As of the date of this Schedule 13D, except as set forth in this Schedule 13D above, the reporting persons do not have any plans or proposals which would result in:

(a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;
(b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;
(c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries;
(d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of the board of directors or management of the Issuer;
(e) Any material change in the present capitalization or dividend policy of the Issuer;
(f) Any other material change in the Issuer's business or corporate structure;
(g) Changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;
(h) Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association;
(i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or

Pursuant to the Private Units Purchase Agreement, Sponsor purchased an aggregate of 322,500 private placement units ("Placement Units") simultaneously with the consummation of the IPO and the over-allotment. The Placement Units and the securities underlying such Placement Units are subject to a lock up provision in the Private Units Purchase Agreement, which provides that such securities shall not be transferable, saleable or assignable until 30 days after the consummation of the Issuer's initial business combination, subject to certain limited exceptions as described in the Insider Letter (as defined below). The description of the Private Placement Units Purchase Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.4 to the Current Report on Form 8-K filed by the Issuer with the SEC on May 4, 2026 (and is incorporated by reference herein as Exhibit 10.1).

Pursuant to the Registration Rights Agreement, the initial shareholders, including Sponsor, and the other parties thereto are entitled to registration rights with respect to certain securities of the Issuer held by them. The holders of a majority of these securities are entitled to make up to three demands that the Issuer register such securities. In addition, the holders have certain piggy-back registration rights with respect to registration statements filed subsequent to consummation of the Issuer's Business Combination. The Issuer will bear the expenses incurred in connection with the filing of any such registration statements. The description of the Registration Rights Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.3 to the Current Report on Form 8-K filed by the Issuer with the SEC on May 4, 2026 (and is incorporated by reference herein as Exhibit 10.2).

Pursuant to the Letter Agreement, Sponsor agreed, among other things, to vote all ordinary shares owned by it, subject to applicable securities laws, in favor of a proposed Business Combination, not to sell or transfer any securities of the Issuer, subject to certain exceptions, until certain periods of time set forth in the Insider Letter Agreement and the Share Escrow Agreement and that it would not seek redemption rights with respect to any ordinary shares held by it. The description of the Insider Letter is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.1 to the Current Report on Form 8-K filed by the Issuer with the SEC on May 4, 2026 (and is incorporated by reference herein as Exhibit 10.3).

Pursuant to the Share Escrow Agreement, Sponsor agreed, among other things, that the shares held by it prior to the IPO may not be transferred, assigned, sold or released from escrow, except for certain permitted transfers, until six months after the date of the consummation of an initial Business Combination, or earlier, if, subsequent to an initial Business Combination, the Issuer consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of the Issuer's shareholders having the right to exchange their shares for cash, securities or other property. The description of the Share Escrow Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.8 to the Current Report on Form 8-K filed by the Issuer with the SEC on May 4, 2026 (and is incorporated by reference herein as Exhibit 10.4).
