NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

NavSight Holdings, Inc. (the “Company”) was incorporated in Delaware on May 29, 2020. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”).

Although the Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination, the Company intends to focus on businesses that provide expertise and technology to U.S. government customers in support of their national security, intelligence, and defense missions. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of June 30, 2021, the Company had not commenced any operations. All activity for the period from May 29, 2020 (inception) through June 30, 2021 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and, subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company’s Initial Public Offering was declared effective on September 9, 2020. On September 14, 2020, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the shares of Class A common stock included in the Units sold, the “Public Shares”), which includes the full exercise by the underwriter of the over-allotment option to purchase an additional 3,000,000 Units, at $10.00 per Unit, generating gross proceeds of $230,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 6,600,000 warrants (each, a “Private Placement Warrant” and, collectively, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to Six4 Holdings, LLC (the “Sponsor”), generating gross proceeds of $6,600,000, which is described in Note 4.

Transaction costs amounted to $13,056,945, consisting of $4,600,000 of underwriting fees, $8,050,000 of deferred underwriting fees and $406,945 of other offering costs.

Following the closing of the Initial Public Offering on September 14, 2020, an amount of $230,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and a portion of the net proceeds of the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) located in the United States and held as cash or invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account, as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding taxes payable on interest income earned from the Trust Account and the deferred underwriting commissions) at the time of the agreement to enter into the initial Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share amount to be distributed to public stockholders who redeem their Public

Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 6). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants.

The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law or stock exchange requirements and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor has agreed to vote their Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction.

Notwithstanding the above, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The Sponsor has agreed (i) to waive its redemption rights with respect to its Founder Shares and Public Shares held by it in connection with the completion of a Business Combination and (ii) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders with the opportunity to redeem their shares in conjunction with any such amendment.

The Company will have until September 14, 2022 to consummate a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes (less up to $100,000 to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

The Sponsor has agreed to waive its right to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriter has agreed to waive its rights to the deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ($10.00).

In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any

claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than our independent auditors), prospective target businesses or other entities with which the Company does business, execute agreements with the Company’s waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Proposed Business Combination

On February 28, 2021, the Company entered into a Business Combination Agreement (the “Transaction Agreement”) by and among the Company, NavSight Merger Sub Inc., a Delaware corporation and direct wholly owned subsidiary of NavSight (“Merger Sub”), Spire Global, Inc., a Delaware corporation (“Spire”), and certain of Spire’s stockholders (the “Founders”). Merger Sub will be merged with and into Spire (the “Merger” and together with the other transactions contemplated by the Transaction Agreement, the “Transactions”), with Spire surviving the Merger. As a result of the Transactions, as further described below, it is expected that the equityholders of Spire, as of immediately prior to the Merger, will hold approximately 65.7% of the fully diluted outstanding equity interests of the Company.

At the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any action on the part of the Company, Merger Sub, Spire or the holders of any of Spire’s securities, each share of outstanding capital stock of Spire (the “Company Capital Stock”) will be canceled and converted into (i) the right to receive at Closing the number of shares of the Company Class A Common Stock (the “Company Class A Common Stock”) based on the pro rata portion applicable to such share of Company Capital Stock, of an aggregate purchase price of approximately $1.1 billion, and (ii) the contingent “earn-out” right to receive a pro rata portion of up to 8,000,000 shares of the Company Class A Common Stock in the aggregate based on the achievement of certain trading price targets following the Closing, which amount of “earn-out” shares will be adjusted based on a formula set forth in the Transaction Agreement to reflect a portion of the value of such “earn-out” shares allocated to holders of Company options assumed by the Company in the Merger.

The Transaction Agreement contains customary representations and warranties of the parties, thereto and the closing is subject to certain conditions as further described in the Transaction Agreement.

For additional information regarding Spire, the Merger Agreement and the Business Combination, see the Current Report on Form 8-K filed by the Company on March 1, 2021. Other than as specifically discussed, this report does not assume the closing of the Business Combination.

Liquidity and Going Concern

As of June 30, 2021, the Company had $401,595 in its operating bank accounts and negative working capital of $1,318,938, which excludes franchise and income taxes payable, as such amounts can be paid from the interest earned in the Trust Account. Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for identifying and evaluating prospective acquisition candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to acquire, and structuring, negotiating and consummating the Business Combination. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans.

The Company will need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the initial stockholders or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants identical to the Private Placement Warrants, at a price of $1.00 per warrant at the option of the lender.

Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern through one year and one day from the date of issuance of these financial statements. These conditions raise substantial doubt about our ability to continue as a going concern. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Risks and Uncertainties

In March 2020, the World Health Organization declared the outbreak of a novel coronavirus (COVID-19) as a pandemic which continues to spread throughout the United States and the World. As of the date the financial statements were issued, there was considerable uncertainty around the expected duration of this pandemic. The Company has concluded that while it is reasonably possible that COVID-19 could have a negative effect on identifying a target company for a Business Combination, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
