that are not historical facts but are forward-looking statements within the meaning of the federal securities laws. Forward-looking statements
generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,”
“anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “project,”
“forecast,” “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, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include,
but are not limited to, statements regarding the development, energization, capacity, cost and timing of the Dyersburg, Tennessee site;
the anticipated benefits of the Valley Oasis acquisition; Atlantic’s utility-approved capacity and development pipeline; changes
in the market for Atlantic’s services and technology, expansion plans and opportunities; and the anticipated benefits, terms and
timing of the Proposed Business Combination. 3 These statements are based on various assumptions,
whether or not identified in this press release, and on the current expectations of Aperture’s and Atlantic’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 any 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 will differ from assumptions. Many actual events
and circumstances are beyond the control of Aperture and Atlantic. These forward-looking statements are subject to a number of risks and
uncertainties, including, but not limited to: the risk that Atlantic may not be able to complete utility construction or fully fund the
[utility construction costs and/or complete substation transformer upgrades at Atlantic’s sole cost to serve the full 29 MW contract
demand at the Dyersburg, Tennessee site; the availability, cost and timing of permits and other development approvals for the site; the
site lease covers approximately one acre and expires in March 2036 without an option to extend, and additional acreage that Atlantic may
require has not been secured and may not be secured on acceptable terms or at all; changes in utility rules and applicable TVA rate schedules;
the risk that the transactions contemplated by the Business Combination Agreement, including the domestication and the merger (the “Transactions”),
may not be completed in a timely manner or at all, which may adversely affect the price of Aperture’s securities; the risk that
the Transactions may not be completed by Aperture’s business combination deadline; the failure by the parties to the Business Combination
Agreement to satisfy the conditions to the consummation of the Transactions, including the approval of Aperture’s shareholders;
failure to realize the anticipated benefits of the Transactions; the level of redemptions of Aperture’s public shareholders which
may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing, or trading of the
Aperture common stock; the failure of Aperture to obtain or maintain the listing of its securities on any national securities exchange
on which Aperture common stock will be listed after the closing of the Proposed Business Combination (the “Closing”); costs
related to the Transactions and as a result of becoming a public company; changes in business, market, financial, political and regulatory
conditions; Atlantic has historically derived substantially all of its revenue to date from bitcoin mining operations and remains heavily
dependent on bitcoin mining for the foreseeable future; volatility in the price of bitcoin and increases in network difficulty may adversely
affect Atlantic’s mining revenue and profitability; Atlantic’s dependence on a single mining pool operator for substantially
all of its mining revenue, and the ability of the pool operator to adjust fee rates; Atlantic’s AI/HPC infrastructure business has
not generated material revenue to date, and there can be no assurance that Atlantic will successfully execute its planned transition from
bitcoin mining to AI/HPC infrastructure services or that it will secure definitive customer agreements for such services; the development
of the Ohio AI Campus is in its early stages, with additional utility approvals, interconnection agreements and infrastructure upgrades
required before full commercial operation, the timing and outcome of which are uncertain; Atlantic has a limited operating history and
a small workforce, which may limit its ability to execute its growth strategy and respond to operational demands; Atlantic’s fixed-delivery
hashrate purchase and sale arrangements and the related derivative liability, including the consequences of non-delivery of bitcoin under
such arrangements; concentration of Atlantic’s equipment supply chain among a limited number of suppliers; Atlantic holds all mined
digital assets in self-custody without a third-party custodian, and does not currently maintain insurance covering loss or theft of digital
assets; Atlantic’s facilities are located in a limited number of states, and any adverse regulatory, environmental or utility-related
development affecting those jurisdictions could disproportionately affect Atlantic’s operations; the reallocation of existing digital
asset mining capacity at the Ohio site to AI/HPC use and the resulting effect on mining revenue; and those risk factors discussed in the
Registration Statement and the other documents that Aperture has filed, or will file, with the SEC relating to the Proposed Business Combination.
If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied
by these forward-looking statements. The risks and uncertainties above are not exhaustive, and there may be additional risks that neither
Aperture nor Atlantic presently know or that Aperture and Atlantic 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 Aperture’s and
Atlantic’s expectations, plans or forecasts of future events and views as of the date of this press release. Aperture and Atlantic
anticipate that subsequent events and developments will cause Aperture’s and Atlantic’s assessments to change. However, while
Aperture and Atlantic may elect to update these forward-looking statements at some point in the future, Aperture and Atlantic specifically
disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing Aperture’s and Atlantic’s
assessments as of any date subsequent to the date of this press release. Accordingly, undue reliance should not be placed upon the forward-looking
statements. Item 9.01 Financial Statements and Exhibits. (d) Exhibits Exhibit No. Description 99.1 Press Release, dated September 30, 2026. 99.2 Investor Presentation, dated September 30, 2026 104 Cover Page Interactive Data File (embedded within the Inline XBRL document). 4 SIGNATURE Pursuant
