INTRODUCTORY NOTE

On July 21, 2025, Pinnacle Growth Acquisition Corp. ("Pinnacle" or "PGAC"), a Cayman Islands exempted company, consummated the previously announced business combination (the "Business Combination") pursuant to the Business Combination Agreement, dated as of April 14, 2025 (as may be amended, supplemented, or otherwise modified from time to time, the "BCA"), by and among Pinnacle, Pinnacle Merger Sub Inc., a Delaware corporation and direct wholly owned subsidiary of Pinnacle ("Merger Sub"), and Skybridge Fintech Ltd., a Delaware corporation ("Skybridge" or "SBF").

The BCA was previously filed as Exhibit 2.1 to the Current Report on Form 8-K filed by Pinnacle with the Securities and Exchange Commission (the "SEC") on April 14, 2025, and is described in detail in the Registration Statement on Form S-4 (File No. 333-294817) (the "Registration Statement"), which includes the proxy statement/prospectus forming a part thereof (the "Proxy Statement/Prospectus"), declared effective by the SEC on June 16, 2025. The description of the BCA and the transactions contemplated thereby contained herein and in the Proxy Statement/Prospectus is qualified in its entirety by reference to the full text of the BCA, which is incorporated herein by reference.

The Business Combination was consummated in two sequential steps:

(i) The Domestication. Pinnacle Growth Acquisition Corp. was re-domiciled from the Cayman Islands to the State of Delaware by deregistering as a Cayman Islands exempted company under the Cayman Islands Companies Act (As Revised) and domesticating as a corporation formed under the laws of the State of Delaware pursuant to Section 388 of the Delaware General Corporation Law (the "DGCL"). In connection with the Domestication, Pinnacle was renamed "Skybridge Fintech Holdings, Inc." (the "Domestication"). Each issued and outstanding ordinary share and warrant of Pinnacle (Cayman Islands) was converted into the corresponding security of the domesticated Delaware corporation, as described more fully in Item 2.01 below.

(ii) The Merger. Immediately following the Domestication, Merger Sub merged with and into Skybridge Fintech Ltd., with Skybridge surviving the Merger as a direct, wholly owned subsidiary of Skybridge Fintech Holdings, Inc. (the "Merger," and together with the Domestication, the "Closing"). The Merger was structured as a forward triangular merger under the DGCL.

As a result of the Closing, Pinnacle Growth Acquisition Corp. ceased to be a shell company as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Unless the context otherwise requires, the "Combined Company" refers to Skybridge Fintech Holdings, Inc., the Delaware corporation, following the consummation of the Business Combination. References to "Pinnacle" refer to Pinnacle Growth Acquisition Corp. prior to the consummation of the Business Combination and the Domestication. References to "Skybridge" or "SBF" refer to Skybridge Fintech Ltd. prior to the consummation of the Merger. Capitalized terms used but not otherwise defined in this Current Report on Form 8-K (this "Report") have the meanings ascribed to such terms in the BCA or the Proxy Statement/Prospectus, as applicable.

Tranche 1: 2,500,000 Earnout Shares will be issued to the former Skybridge stockholders (on a pro rata basis based on their respective ownership of Skybridge common stock immediately prior to the Merger) if the VWAP of the Combined Company's common stock equals or exceeds $12.50 per share for any twenty (20) trading days within any thirty (30) consecutive trading day period during the twenty-four (24)-month period commencing on the Closing Date.

Tranche 2: 2,500,000 Earnout Shares will be issued to the former Skybridge stockholders (on a pro rata basis) if the VWAP of the Combined Company's common stock equals or exceeds $15.00 per share for any twenty (20) trading days within any thirty (30) consecutive trading day period during the thirty-six (36)-month period commencing on the Closing Date.

The Earnout Agreement contains customary anti-dilution and equitable adjustment provisions that provide for proportional adjustments to the number of Earnout Shares and the applicable VWAP thresholds in the event of stock splits, reverse stock splits, stock dividends, reclassifications, recapitalizations, or similar transactions affecting the outstanding shares of Combined Company common stock. In addition, the Earnout Agreement provides that upon the consummation of a Change of Control (as defined therein) of the Combined Company during the applicable earnout measurement period, all then-unvested Earnout Shares will be deemed earned and will be issued immediately prior to the consummation of such Change of Control, regardless of whether the applicable VWAP thresholds have been achieved at such time.

ITEM 2.01 — COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS

Overview of the Business Combination

On July 21, 2025, the Business Combination contemplated by the BCA, dated as of April 14, 2025, was consummated. As a result of the Business Combination, Skybridge Fintech Ltd. became a direct, wholly owned subsidiary of Skybridge Fintech Holdings, Inc. (formerly known as Pinnacle Growth Acquisition Corp.), the shares of common stock of the Combined Company commenced trading on the Nasdaq Capital Market under the ticker symbol "SBFT," and the Combined Company ceased to be a shell company.

The Domestication. Immediately prior to the consummation of the Merger, the Domestication was completed. Pinnacle Growth Acquisition Corp. was re-domiciled from the Cayman Islands to the State of Delaware by filing a Certificate of Domestication under Section 388 of the DGCL with the Secretary of State of the State of Delaware, and by deregistering as a Cayman Islands exempted company. In connection with the Domestication, Pinnacle was renamed "Skybridge Fintech Holdings, Inc." and adopted an Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, each effective as of the Domestication.

In connection with the Domestication:

(a) Each issued and outstanding Class A ordinary share, par value $0.0001 per share, of Pinnacle (Cayman Islands) was converted on a one-for-one basis into one share of common stock, par value $0.0001 per share, of Skybridge Fintech Holdings, Inc. (Delaware).

(b) Each issued and outstanding Class B ordinary share, par value $0.0001 per share, of Pinnacle (Cayman Islands) held by the Sponsor was converted on a one-for-one basis into one share of common stock, par value $0.0001 per share, of Skybridge Fintech Holdings, Inc. (Delaware), after giving effect to the Sponsor forfeiture described below.

(c) Each outstanding warrant to purchase Class A ordinary shares of Pinnacle (Cayman Islands) became exercisable for one share of common stock of Skybridge Fintech Holdings, Inc. (Delaware) on the same terms and conditions as were in effect immediately prior to the Domestication, including an exercise price of $11.50 per share and the same expiration date.

The Merger. Following the completion of the Domestication, Merger Sub merged with and into Skybridge Fintech Ltd., with Skybridge surviving the Merger as a direct, wholly owned subsidiary of Skybridge Fintech Holdings, Inc. The Merger was structured as a forward triangular merger under the DGCL.

At the effective time of the Merger (the "Effective Time"):

(a) Each outstanding share of common stock of Skybridge Fintech Ltd. (other than shares held in treasury or held by Pinnacle or Merger Sub, which were cancelled for no consideration) was converted into the right to receive shares of common stock of the Combined Company at a deemed value of $10.00 per share, resulting in the issuance of an aggregate of 45,000,000 shares of Combined Company common stock to the former Skybridge stockholders, reflecting an implied equity value of $450,000,000 for Skybridge.

(b) Each outstanding option to purchase shares of Skybridge common stock, whether vested or unvested, was assumed by the Combined Company and converted into an option to purchase shares of Combined Company common stock, with appropriate adjustments to the exercise price and the number of shares subject to each such option, based on the exchange ratio established in the BCA, such that the aggregate intrinsic value of the option immediately after the Merger was equal to the aggregate intrinsic value of the option immediately prior to the Merger.

(c) Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time was converted into one validly issued, fully paid, and non-assessable share of common stock of Skybridge Fintech Ltd. (as the surviving entity in the Merger).

Consideration and Deal Value

The material terms of the consideration payable in the Business Combination are summarized as follows:

• Implied enterprise value of Skybridge: $450,000,000

• Per-share merger consideration: $10.00

• Total shares issued to former Skybridge stockholders: 45,000,000 shares of Combined Company common stock

• Implied valuation multiples: Approximately 5.15× Skybridge's fiscal year 2024 revenue of $87.3 million and approximately 4.76× Skybridge's fiscal year 2024 annualized recurring revenue ("ARR") of $94.6 million

The foregoing equity consideration excludes (i) up to 5,000,000 Earnout Shares issuable upon the achievement of specified stock price milestones as described in Item 1.01 above, (ii) shares issuable upon exercise of assumed Skybridge stock options, and (iii) shares issuable upon exercise of the Combined Company's outstanding warrants.

PIPE Closing. Concurrently with the Closing, the PIPE Investors purchased an aggregate of 15,000,000 shares of Combined Company common stock at a price of $10.00 per share, for aggregate gross proceeds to the Combined Company of $150,000,000, pursuant to the respective subscription agreements (the "Subscription Agreements") entered into in connection with the execution of the BCA. The PIPE investment was allocated among the PIPE Investors as follows:

The shares of Combined Company common stock issued to the PIPE Investors were issued in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), provided by Section 4(a)(2) thereof and/or Regulation D promulgated thereunder, and will be registered for resale pursuant to the Registration Rights Agreement described in Item 1.01 above.

Backstop. Pursuant to the Non-Redemption/Backstop Agreement, dated as of April 14, 2025 (the "Backstop Agreement"), Velthryn Strategic Investments, LP ("Velthryn"), committed to purchase up to 5,000,000 shares of Combined Company common stock from stockholders who had elected to redeem their shares in connection with the Business Combination, at a price of $10.25 per share, for a maximum aggregate commitment of $51,250,000. At the Closing, Velthryn purchased [●] shares from redeeming stockholders at $10.25 per share, for an aggregate purchase price of $[●]. In consideration of its backstop commitment, Velthryn received incentive shares equal to 10% of the number of backstop shares actually purchased, or [●] incentive shares. Richard Tsai, Managing Director of Velthryn, oversaw the execution and funding of the backstop commitment.

The foregoing description of the Backstop Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Backstop Agreement, a copy of which was previously filed as Exhibit 10.6 to the Current Report on Form 8-K filed on April 14, 2025, and is incorporated herein by reference.

Redemptions. In connection with the Extraordinary General Meeting of Pinnacle's shareholders held on July 18, 2025 (the "EGM"), at which the Business Combination and related proposals were approved, holders of [●] of the 30,000,000 issued and outstanding Class A ordinary shares of Pinnacle validly elected to exercise their redemption rights, representing approximately [●]% of the outstanding Class A ordinary shares. Each redeeming shareholder received a per-share redemption price of approximately $[●] (based on the aggregate trust balance of approximately $312,600,000 as of March 31, 2025, plus accrued interest through the date of redemption, divided by 30,000,000 shares, net of taxes payable on trust earnings and dissolution expenses allocable to the trust).

After giving effect to the redemptions and the backstop, [●] shares of Combined Company common stock that were formerly Class A ordinary shares of Pinnacle remained outstanding as part of the public float.

Sponsor Forfeiture. Pursuant to the Sponsor Support Agreement, dated as of April 14, 2025 (the "Sponsor Support Agreement"), Ridgeway Capital Holdings LLC (the "Sponsor") agreed to forfeit a portion of its 7,500,000 Class B ordinary shares of Pinnacle in connection with the Closing, as described below:

(a) At the Closing, the Sponsor forfeited 500,000 Class B ordinary shares of Pinnacle (prior to the conversion of such shares into shares of Combined Company common stock in the Domestication), for no consideration.

(b) In the event that redemptions exceeded 75% of the outstanding public shares (i.e., more than 22,500,000 of the 30,000,000 Class A ordinary shares were tendered for redemption), the Sponsor was required to forfeit an additional 500,000 Class B ordinary shares, resulting in a total forfeiture of 1,000,000 shares and the Sponsor retaining 6,500,000 shares of Combined Company common stock following the Domestication.

(c) In the event that redemptions did not exceed 75% of the outstanding public shares, the Sponsor retained 7,000,000 shares of Combined Company common stock following the Domestication (after the initial forfeiture of 500,000 shares).

The foregoing description of the Sponsor Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Sponsor Support Agreement, a copy of which was previously filed as Exhibit 10.4 to the Current Report on Form 8-K filed on April 14, 2025, and is incorporated herein by reference.

Trust Account Disbursement

In connection with the Closing, the funds held in Pinnacle's trust account at Glenridge National Bank, N.A. were released and applied as follows:

The Minimum Cash Condition set forth in the BCA was satisfied at Closing. The BCA required that the Combined Company have "Available Cash" (as defined in the BCA) of at least $200,000,000 at the Closing. Available Cash is defined as the sum of (a) the aggregate amount of cash remaining in the trust account (net of amounts paid to redeeming shareholders), plus (b) the aggregate gross proceeds received from the PIPE investment, plus (c) the aggregate gross proceeds received from the backstop investment, minus (d) aggregate transaction expenses payable at or in connection with the Closing. Based on the amounts described above, the Available Cash at the Closing was $[●], which exceeded the $200,000,000 minimum threshold.

The following table sets forth the pro forma capitalization of the Combined Company, assuming that no holders of Pinnacle's Class A ordinary shares exercised their redemption rights in connection with the Business Combination:

The table above excludes the following securities that were outstanding as of the Closing Date and that are exercisable for or convertible into shares of Combined Company common stock: (i) 8,000,000 private placement warrants held by the Sponsor, each exercisable for one share of common stock at an exercise price of $11.50 per share; (ii) 10,000,000 public warrants, each exercisable for one share of common stock at an exercise price of $11.50 per share; and (iii) up to 5,000,000 Earnout Shares issuable upon the achievement of specified VWAP milestones as described in Item 1.01 above.

Actual redemption levels and backstop purchases will determine the final capitalization of the Combined Company.

ITEM 3.01 — NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE OR STANDARD; TRANSFER OF LISTING

In connection with the Closing, on July 21, 2025, the Combined Company's shares of common stock and warrants commenced trading on the Nasdaq Capital Market under the new ticker symbols "SBFT" (common stock) and "SBFTW" (warrants), respectively. Pinnacle's Class A ordinary shares (formerly trading under the ticker symbol "PGAC"), units (formerly trading under the ticker symbol "PGACU"), and warrants (formerly trading under the ticker symbol "PGACW") ceased trading on the Nasdaq Capital Market prior to the open of trading on July 21, 2025. Each unit of Pinnacle that had not previously been separated into its component parts was automatically separated into one share of Combined Company common stock and one-half of one public warrant in connection with the Domestication and the Closing.

The Combined Company's listing application was submitted to The Nasdaq Stock Market LLC on May 5, 2025, and approval of the listing of the Combined Company's common stock and warrants on the Nasdaq Capital Market was received prior to the Closing Date.

ITEM 3.03 — MATERIAL MODIFICATION TO RIGHTS OF SECURITY HOLDERS

In connection with the Domestication, the rights of holders of the Combined Company's securities were materially modified as a result of the conversion of Pinnacle's Cayman Islands securities into securities of a Delaware corporation. As described in Item 2.01 above, each issued and outstanding Class A ordinary share of Pinnacle was converted on a one-for-one basis into one share of common stock of the Combined Company, and each issued and outstanding Class B ordinary share of Pinnacle (held by the Sponsor) was converted on a one-for-one basis into one share of common stock of the Combined Company (after giving effect to the Sponsor forfeiture). Accordingly, the dual-class share structure that existed under Pinnacle's Cayman Islands Memorandum and Articles of Association was eliminated. All shares of Combined Company common stock carry one vote per share.

Holders of Pinnacle's Cayman Islands ordinary shares now hold shares of common stock of a corporation organized under the laws of the State of Delaware. The rights, preferences, and privileges of such shares are governed by the DGCL and the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws of Skybridge Fintech Holdings, Inc. The following is a summary of the key changes in the rights of security holders as a result of the Domestication:

Elimination of Dual-Class Structure. Prior to the Domestication, Pinnacle had two classes of ordinary shares: Class A ordinary shares (held by public investors) and Class B ordinary shares (held by the Sponsor). Following the Domestication, the Combined Company has a single class of common stock. Each share of common stock is entitled to one vote on all matters submitted to a vote of stockholders.

Appraisal Rights. Under Cayman Islands law, shareholders of Pinnacle were entitled to fair value appraisal rights in certain circumstances as provided under the Cayman Islands Companies Act. Following the Domestication, stockholders of the Combined Company are entitled to appraisal rights under Section 262 of the DGCL in connection with certain mergers and consolidations, subject to the conditions and limitations set forth therein.

Classified Board of Directors. The Amended and Restated Certificate of Incorporation provides for a classified board of directors, divided into three classes, with each class serving staggered three-year terms.

ITEM 5.01 — CHANGES IN CONTROL OF REGISTRANT

As a result of the consummation of the Business Combination, a change of control of the registrant occurred. The former stockholders of Skybridge Fintech Ltd. collectively hold the largest block of shares of Combined Company common stock, consisting of 45,000,000 shares (representing approximately 46.4% of the outstanding shares of common stock, assuming no redemptions, or approximately 58.4% of the outstanding shares, in the maximum redemption scenario with the backstop).

The key pre-transaction stockholders of Skybridge and their approximate ownership interests in Skybridge (on a fully diluted basis) immediately prior to the Merger were as follows:

Following the Closing, the Sponsor (Ridgeway Capital Holdings LLC, which is controlled by Jonathan Mercer) holds 7,000,000 shares of Combined Company common stock (representing approximately 7.2% of the outstanding shares, assuming no redemptions) or 6,500,000 shares (representing approximately 8.4% of the outstanding shares, in the maximum redemption scenario). In addition, the Sponsor holds 8,000,000 private placement warrants exercisable for shares of Combined Company common stock at an exercise price of $11.50 per share.

The source of consideration used in effecting the change of control was the issuance of shares of Combined Company common stock to former Skybridge stockholders as merger consideration, the issuance of shares of Combined Company common stock to the PIPE Investors in exchange for aggregate cash proceeds of $150,000,000, and the release of funds held in Pinnacle's trust account at Glenridge National Bank, N.A. No cash consideration was paid to the former stockholders of Skybridge; the Merger was effected entirely through the issuance of equity securities.
