TECFUSIONS INC. | CONFIDENTIAL 3 Important Disclaimer Financial and Other Information The financial information contained in this presentation has been taken from or prepared based on unaudited historical financial statements of TECfusions and its constituent businesses. The audit of these financial statements of TECfusions is in process. Accordingly, such financial information and data may not be included in, may be adjusted in or may be presented differently in any proxy statement/prospectus to be filed with the SEC by Apex Treasury or TECfusions in connection with the proposed transaction. This presentation contains certain preliminary financial results and key operating metrics for the period ended December 31, 2025. This information is preliminary and subject to change. As such, TECfusions's results may differ from the preliminary results presented herein and will not be finalized until TECfusions' audit for the period ended December 31, 2025, is completed. This presentation includes certain non-GAAP financial measures (including on a forward-looking basis) such as EBITDA. These non-GAAP measures are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to net income or any other measures derived in accordance with GAAP. TECfusions believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about TECfusions. TECfusions' management uses forward-looking non-GAAP measures to evaluate TECfusions' projected financial and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including [that they exclude significant expenses that are required by GAAP to be recorded in TECfusions' financial measures]. In addition, other companies may calculate non-GAAP measures differently or may use other measures to calculate their financial performance, and therefore, TECfusions' non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. Investors and security holders of Apex Treasury are used to read the Registration Statement and the proxy statement/prospectus which forms a part thereof and other relevant documents that will be filed with the SEC carefully and in their entirety when they become available because they will contain important information about the proposed transaction. Use of Projections The financial projections, estimates and targets in this presentation are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond TECfusions or Apex Treasury's control. While all financial projections, estimates and targets are necessarily speculative, TECfusions and Apex Treasury believe that the presentation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the financial projections, estimates and targets to be a reliable prediction of future events. Neither TECfusions nor Apex Treasury's independent auditors have reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and, accordingly, neither of them has expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. Additional Information About the Proposed Transaction and Where to Find It The proposed transaction will be submitted to shareholders of Apex Treasury for their consideration. Apex Treasury and TECfusions intend to file a registration statement on Form S-4 (the "Registration Statement") with the SEC, which will include preliminary and definitive proxy statements to be distributed to Apex Treasury's shareholders in connection with Apex Treasury's solicitation for proxies for the vote by Apex Treasury's shareholders in connection with the proposed transaction and other matters to be described in the Registration Statement, as well as the prospectus relating to the offer of the securities to be issued to TECfusions' shareholders in connection with the completion of the proposed transaction.

Risk Factors For a description of certain risks relating to TECfusions, including its business and operations, and to the proposed transaction, we refer you to "Risk Factors" at the end of this presentation. Use of Data Information in this presentation is based on data and analyses from various sources as of July 2026, unless otherwise indicated. References in this presentation to "$" are to the lawful currency of the United States. This presentation also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other industry data. These estimates and other statistical data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates and other statistical data. We have not independently verified the statistical and other industry data generated by independent parties and contained in this presentation and, accordingly, we cannot guarantee their accuracy or completeness. In addition, expectations, assumptions, estimates and projections of the future performance of relevant markets in which TECfusions operates are necessarily subject to a high degree of uncertainty and risk.

Accordingly, such information and data may not be included in, may be adjusted in, or may be presented differently in, any registration statement, prospectus, proxy statement or other report or document to be filed or furnished with the SEC by TECfusions, Apex Treasury or the Combined Company in connection with the proposed transaction. Use of Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, including Net Income from Operations. Net Income from Operations is defined as net income (loss) plus interest expense, net, provision for income taxes plus depreciation and amortization. TECfusions believes that this non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to TECfusions' financial condition and results of operations. Management of TECfusions does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. We have not reconciled the non-GAAP forward-looking information to their corresponding GAAP measures because we do not provide guidance for the various reconciling items such as provision for income taxes and depreciation and amortization, as certain items that impact these measures are out of our control or cannot be reasonably predicted without unreasonable efforts. You should review TECfusions' and its subsidiaries, financial statements, which will be included in Apex Treasury's proxy statement filings with the SEC, and not rely on any single financial measure to evaluate TECfusions' business. Other companies may calculate Net Income from Operations and other non-GAAP measures differently, and therefore TECfusion's Net Income from Operations and other non- GAAP measures may not be directly comparable to similarly titled measures of other companies.

TECFUSIONS INC. | CONFIDENTIAL 12 Fast & Vertical: Used Factory Plant Reconfiguration CORE CONCEPT TECfusions acquires and repurposes existing industrial buildings into sustainable, high-performance data centers—delivering faster deployment, lower environmental impact, and infrastructure that serves both the digital economy and local communities. Time & Cost Advantage • Time-to-Market: Our Adaptive Reuse model makes us significantly faster than average greenfield construction, driven by existing zoning, structural shell, and expected utility access • Capital Efficiency: significantly lower upfront CapEx vs. ground-up builds through reuse of existing site infrastructure • Permitting & Zoning: Industrial-zoned sites generally reduce entitlement risk, approval cycles, and environmental review complexity vs. greenfield parcels • Infrastructure in Place: Existing power corridors, utility easements, road access, drainage, and structural shells materially reduce scope, cost, and schedule risk Competitive Differentiation • Time-to-Market: Competitors typically optimize for scale over speed, accepting multi-year development cycles and higher upfront capital intensity • Multidisciplinary Due Diligence: Adaptive reuse demands integrated evaluation across engineering, power, environmental, zoning, and financial domains—capabilities many competitors are not structured to execute simultaneously • Target Portfolio: Focus on underutilized or legacy industrial properties in power-constrained or strategically emerging markets • Capital Deployment: Adaptive reuse allows TECfusions to deploy capital incrementally, matching supply with contracted demand while preserving balance-sheet efficiency We believe TECfusions competes where greenfield developers may have difficulties unlocking speed, capital efficiency, and scalability through its disciplined reuse of existing industrial infrastructure. Source: Management estimates.

TECFUSIONS INC. | CONFIDENTIAL 13 Fast & Vertical: On-Site Power Generation A HUGE DIFFERENTIATOR VS. COMPETITORS TECfusions integrates on-site power generation directly into its data center development model—structurally separating itself from many of the traditional operators that remain dependent on constrained utility grids. Power Economics • Predictable, contracted energy pricing; reduced exposure to congestion pricing, demand charges, and curtailment risk • Modular MW-block deployment aligned to leasing for rapid energization and scalable expansion • Integrated power + optimized cooling supports lower total delivered $/kW and improved operating leverage Reliability & Control • Utility-independent uptime and enterprise- grade SLAs for hyperscale and AI workloads • Reduced exposure to grid outages, congestion events, load shedding, and interconnection delays • Purpose-built turbine-led and microgrid- ready architectures with layered redundancy for always-on compute vs. Competitors • Most operators rely on grid power, subject to congestion, demand charges, and third- party interconnection timelines • New capacity constrained by multi-year utility queue backlogs and regional transmission approvals • TECfusions develops power, site, and facility as one integrated system—enabling faster energization and cost control

TECFUSIONS INC. | CONFIDENTIAL 14 Power Strategy: Grid-Dependent vs. TECfusions Integrated Model (1) Grid-Dependent Model Utility Grid Substation Data Center • Reliant on utility grid capacity • Long interconnection queues • Exposed to rate volatility • Limited scalability in constrained markets • Schedule risk tied to utility timelines TECfusions Integrated Model (1) On-Site Power Generation TECfusions Power Control Data Center Campus • On-site power owned & controlled • Grid as supplement, not dependency • Predictable energy costs • Faster deployment in constrained markets • Scalable capacity beyond grid queues TECfusions removes grid dependency by integrating on-site power—unlocking speed, cost control, and scalability that is difficult for traditional models to replicate.

TECFUSIONS INC. | CONFIDENTIAL 24 TECfusions : 3-Year Financial Forecast 2026 $110M Total Revenue 2027 $289M Total Revenue 2028 $2.14B Total Revenue $4.81B $6.77B Total Expenses ($23M) Net Income ($20M) Interest Expense ($66M) D&A ($41M) Net Income from Operations $87M Total Expenses ($47M) Net Income ($10M) Interest Expense ($145M) D&A ($107M) Net Income from Operations $242M Total Expenses ($252M) Net Income $189M Interest Expense ($1.0B) D&A ($681M) Net Income from Operations $1.88B ($652M) ($1.02B) Key assumptions • Revenue is primarily derived from recurring monthly fees based on the quantum of power per client at a fixed price per kW, with annual escalators and subject to multi-year contractual obligations. • Additional revenue is assumed to be derived through the build out of compute capacity and is assumed to be placed in service with the addition of 42 MW during 2026, a further 350 MW during 2027 and a further 1,045 MW during 2028. These expansions are factored into the revenue forecast during various points during each year. • At the end of 2026, 2027 and 2028 the total capacity in service, and generating revenue, is assumed to be 92 MW, 422 MW and 1,467 MW respectively. • Additional revenue is assumed to accrue from having an on-site power plant operating at New Kensington from Q4 '27 onwards and is assumed to contribute approximately $0.5B in revenue during 2028. • Capital expenditures, incurred to build out the additional capacity, including the New Kensington power plant, are assumed to be $1.4B, $16.9B and $16.1B in each of 2026, 2027 and 2028, respectively, and are assumed to be debt financed with annual interest rates in the range of approximately 6% to 13%. • The capitalized data center infrastructure costs and power plant costs are assumed to be depreciated over the estimated useful life of 25 years. Key risks • TECfusions may be unable to expand capacity at the pace forecasted, in which case revenue may be be less than forecast. • TECfusions may be unable to secure the cash required to adequately fund its capital expenditure requirements on terms acceptable to TECfusions, at the assumed interest rates, noted, or at all. • TECfusions may be unable to acquire customers to occupy its data centers on terms subject to the above assumptions, or at all, which would materially affect projected revenue.
