Information Contained in this Form 6-K Report

Completion of Business Combination and Change of Control

On April 24, 2026, OIO Group (the “Company”) completed its previously announced business combination with De Tomaso Automobili Holdings Limited (“De Tomaso”) (the “Business Combination”).

As a result of the Business Combination, De Tomaso became a subsidiary of the Company, and a change of control of the Company occurred.

Following closing, Norman Choi, founder of De Tomaso, became the Company’s largest shareholder and, based on the Company’s post-closing capitalization, beneficially owns approximately 67.6% of the Company’s issued and outstanding ordinary shares.

Reverse Stock Split

In connection with the Business Combination, the Company effected a one-for-three (1-for-3) reverse stock split of its issued and outstanding ordinary shares, effective April 24, 2026.

The reverse stock split was approved by the Company’s shareholders at the extraordinary general meeting held on June 10, 2025, with the final ratio determined by the Company’s board of directors immediately prior to effectiveness.

The Company’s ordinary shares commenced trading on The Nasdaq Capital Market on a split-adjusted basis under the ticker symbol “OIO” on April 24, 2026.

Issuance of Consideration Shares and Post-Closing Capitalization

In connection with the Business Combination, the Company issued an aggregate of 333,333,334 ordinary shares to the shareholders of De Tomaso as consideration for the transaction.

Following the effectiveness of the reverse stock split and the issuance of the consideration shares, the Company has 348,022,108 ordinary shares issued and outstanding.

Based on the Company’s post-closing capitalization, the former shareholders of De Tomaso hold approximately 95.8% of the Company’s issued and outstanding ordinary shares.

The foregoing ownership percentages are based on the Company’s issued and outstanding ordinary shares immediately following the closing of the Business Combination and the effectiveness of the reverse stock split, and do not give effect to the exercise of outstanding warrants, options or other convertible or exercisable securities, unless otherwise stated.

Board of Directors and Management

As of the date of this Report, the Company’s existing board of directors and management team remain in place. The Company intends to reconstitute its board of directors and implement related senior management changes following the filing of its annual report on Form 20-F for the fiscal year ended December 31, 2025. The Company expects such governance transition to align the Company’s leadership structure with its post-combination strategy. Details of such changes will be disclosed in a subsequent Report on Form 6-K and/or press release, as appropriate.

Prior Pro Forma Financial Information

The Company previously furnished unaudited pro forma condensed financial information reflecting the Business Combination in a Report on Form 6-K filed with the Securities and Exchange Commission on April 22, 2026. This Report does not include or re-furnish such pro forma financial information.

Strategic Positioning

Following the completion of the Business Combination, the Company is positioned as a Nasdaq-listed platform focused on building and supporting distinctive operating businesses with strong brand equity, engineering capability and long-term value creation potential.
