Business Combination Agreement financial

"entered into a Business Combination Agreement (the “Business Combination Agreement”) with NorthStar Earth and Space Inc."

A business combination agreement is a detailed contract that lays out the terms for two companies to join together—covering price, how ownership will be split, the steps needed to close the deal, and what each side promises to do or avoid before closing. For investors it matters because the agreement determines potential changes in value, control, timing, and risk exposure—think of it like the playbook for a merger that shows who wins, who pays, and what could still derail the plan.

Amendment No. 1 financial

"entered into Amendment No. 1 to Business Combination Agreement (the “Amendment”)."

Form F-4 regulatory

"intends to file with the Securities and Exchange Commission a registration statement on Form F-4"

Form F-4 is an official filing with the U.S. Securities and Exchange Commission used by non-U.S. companies when they offer securities in connection with mergers, acquisitions, exchange offers or similar transactions. It acts like a detailed product label or instruction manual that explains the deal, the securities being offered, financials, risks and voting requirements, and it matters to investors because it provides the essential facts needed to evaluate how the transaction could affect ownership, value and future returns.

Proxy Statement regulatory

"a proxy statement to be distributed to holders of Viking’s Class A ordinary shares"

A proxy statement is a document companies send to shareholders ahead of a meeting that lays out the items up for a vote—like who will sit on the board, executive pay, and major corporate decisions—and provides background so shareholders can decide how to cast their votes or appoint someone to vote for them. Think of it as an agenda plus a ballot and briefing notes, important because the outcomes can change control, strategy, and value.

PIPE Financing financial

"ability to successfully consummate the PIPE Financing, or obtain additional financing"

Pipe financing is a way for companies to raise money quickly by selling new shares or bonds directly to investors, often before their stock is publicly traded or in the early stages of a project. It’s similar to a company securing a loan from investors, providing quick capital needed for growth or operations. For investors, it can offer opportunities for early involvement and potentially higher returns, but it may also carry increased risk due to the immediate nature of the deal.

forward-looking statements regulatory

"includes forward-looking statements. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,”"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Forward-Looking Statements

This Current Report on Form 8-K includes forward-looking statements. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity; financing and other business milestones; potential benefits of the proposed Business Combination and other related transactions; and expectations relating to the proposed Business Combination and other related transactions. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K, and on the current expectations of NorthStar’s and Viking’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by an investor as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions. Many actual events and circumstances are beyond the control of NorthStar and Viking. These forward-looking statements are subject to a number of risks and uncertainties, including but not limited to changes in domestic and foreign business, market, financial, political, and legal conditions; the inability of the parties to successfully or timely consummate the proposed Business Combination and other related transactions, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions (such as any SEC statements or enforcements or other actions relating to SPACs) that could adversely affect the combined company or the expected benefits of the proposed Business Combination and other related transactions; failure to realize the anticipated benefits of the proposed Business Combination and other related transactions; ability to successfully consummate the PIPE Financing, or obtain additional financing; ability to attract and retain qualified personnel; global economic and political conditions; the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement; legal and regulatory changes; the outcome of any legal proceedings that may be instituted against Viking or NorthStar related to the proposed Business Combination; the effects of competition on NorthStar’s future business; the approval by Viking’s public shareholders of the Business Combination and related transactions, the amount of redemption requests made by Viking’s public shareholders. Additional risks related to NorthStar’s business include, but are not limited to: The development of advanced data analytics services is complex, and delays could adversely affect NorthStar’s business and prospects; NorthStar may be unable to adequately control the costs associated with its operations and the components necessary to develop and commercialize its data analytics technology; NorthStar may not accurately estimate future supply and demand for its analytics services, leading to inefficiencies and hindering its ability to generate revenue and profits; NorthStar’s expectations and targets regarding technical, pre-production, and production objectives depend on assumptions and analyses that may prove incorrect, affecting milestone achievement; if NorthStar’s existing customers do not continue to purchase its analytics services, its revenue and results of operations would be adversely impacted; NorthStar is an early-stage company with a history of financial losses and expects to incur significant expenses and continuing losses from operations; NorthStar’s business plan has yet to be tested, and it may not succeed in executing on its strategic plans, including commercialization; NorthStar relies heavily on its intellectual property portfolio. If it is unable to protect its intellectual property rights, its business and competitive position would be harmed; NorthStar may need to defend itself against intellectual property infringement claims, which may be time-consuming and could cause it to incur substantial costs or limit its ability to use certain technology; governmental trade controls, including export and import controls, sanctions, customs requirements and related regimes, could subject NorthStar to liability or loss of contracting privileges, limit its ability to transfer technology or compete in certain markets and affect its ability to hire qualified personnel; and changes in U.S., Canadian and foreign government policy, including the imposition of or increases in tariffs and changes to existing trade agreements, could have a material adverse effect on global economic conditions and NorthStar’s business, financial condition, results of operations and prospects. Additional risks related to Viking include those factors set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the IPO Prospectus, and in those documents that Viking has filed, or will file, with the SEC.

If any of these risks materialize or Viking’s or NorthStar’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Viking nor NorthStar presently know or that Viking and NorthStar currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Viking’s and NorthStar’s expectations, plans, or forecasts of future events and views as of the date of this Current Report on Form 8-K and are qualified in their entirety by reference to the cautionary statements herein. Viking and NorthStar anticipate that subsequent events and developments will cause Viking’s and NorthStar’s assessments to change. These forward-looking statements should not be relied upon as representing Viking’s and NorthStar’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither Viking, NorthStar nor any of their respective affiliates undertake any obligation to update these forward-looking statements, except as required by law.
