About the proposed UK Retail Offer
The Company has filed a registration statement on Form S-1 (the "Registration Statement") with the SEC relating to the proposed initial public offering of shares of Class A common stock in the capital of the Company (the "Shares") (the "Global Offering"). If the Global Offering proceeds, it is expected that a public offer of Shares to persons who are resident and physically located in the United Kingdom ("UK Retail Investors") will be facilitated through the public offer platform ("POP") operated by RetailBook in accordance with the rules of the FCA (the "UK Retail Offer").
If the proposed Global Offering proceeds, a further announcement will be made by RetailBook to announce the launch of the UK Retail Offer. RetailBook would act as POP operator, an entity authorised by the FCA to operate an electronic system by means of which securities are offered to the public in the United Kingdom (the "POP Operator"). UK Retail Investors would be able to take part in the proposed UK Retail Offer through, and in order to participate would need to be a client of, a participating retail intermediary that has been onboarded by RetailBook (each a "Participating Intermediary"). Only Participating Intermediaries would be able to access the platform operated by RetailBook (the "RetailBook Platform").
There can be no assurance as to whether or when the Global Offering may be completed, or as to the actual size or terms of the Global Offering. The UK Retail Offer will not be completed without the Global Offering also being completed.
If the proposed UK Retail Offer proceeds, UK Retail Investors who apply to participate in the UK Retail Offer in US dollars would be applying for shares of Class A common stock in the capital of the Company and UK Retail Investors who apply to participate in the UK Retail Offer in pounds sterling would (unless otherwise informed by their Participating Intermediary) be applying for CREST depository interests representing rights to the shares of Class A common stock in the capital of the Company on a one-for-one basis ("CDIs"), and not the shares of Class A common stock themselves. CDIs are a separate instrument to the Shares, constituted under English law and held and settled through CREST (the UK's electronic settlement system). The terms of the CDIs, and the differences between holding CDIs and holding shares of Class A common stock in the capital of the Company, will, if the UK Retail Offer proceeds, be set out in the disclosure summary relating to the UK Retail Offer (the "Disclosure Summary"). References in this announcement to Shares include, where the context requires, CDIs.
There is no minimum allocation of Shares to the UK Retail Offer and the Company may decide not to allocate any Shares to the UK Retail Offer.

Neither the SEC nor any state securities commission has approved or disapproved of these Shares or passed on the adequacy or accuracy of the U.S. Prospectus. Any representation to the contrary is a criminal offence.
