Cat Holdings ("Red Cat" or the "Company") was originally incorporated in February 1984. Since April 2016, the
Company's primary business has been to provide products, services and solutions to the drone industry which it presently does
through its five wholly owned subsidiaries. Teal Drones is a leader in commercial and government UAV technology. Fat Shark Holdings
is a provider of First Person View (FPV) video goggles. Rotor Riot sells FPV drones and equipment, primarily
to the consumer marketplace. Skypersonic provides software and hardware
solutions that enable drones to complete inspection services in locations where GPS (global positioning systems) are not available,
yet still record and transmit data even while being operated from thousands of miles away. Red Cat Propware is developing drone
flight data analytics and storage solutions, as well as diagnostic products and services.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In
February 2021, the Company entered into Share Purchase and Liquidity Event Agreements (the "Skypersonic Agreements") with
the founder and majority shareholder of Skypersonic, Inc., ("Skypersonic") and the holders of common stock and equity based
agreements representing 97.46% of Skypersonic (the "Sellers"), pursuant to which, subject to the satisfaction of certain
closing conditions, the Company would acquire all of the issued and outstanding share capital of Skypersonic for an aggregate of
$&lt;span id="xdx_903_ecustom--AcquisitionShareConsiderationAcquiredValue_c20210501__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zMQYQY3Tbvrf"&gt;3,000,000 &lt;/span&gt;in
shares (the "Share Consideration") of the Company's common stock, based upon the VWAP of the Company's common stock at
closing of the transaction (the "Skypersonic Transaction"). Prior to the closing, the Company provided $&lt;span id="xdx_90D_ecustom--OperatingCostsOfAcquireePaidForByCompanyPriorToAcquisitionClosing_c20210501__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zVlWkoyQxBVe"&gt;75,000 &lt;/span&gt;to
fund operating costs of Skypersonic. This amount was capitalized as part of the purchase price. The transaction closed on May 7,
2021 and was paid through the issuance of &lt;span id="xdx_90E_ecustom--AcquisitionStockIssuedShares_c20210501__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zhkpTTwYl8lb"&gt;857,124 &lt;/span&gt;shares
of common stock which had a fair market value of $&lt;span id="xdx_900_ecustom--AcquisitionStockIssuedValue_c20210501__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zKr1RuGVzHX7"&gt;3,291,356&lt;/span&gt;.
Fifty (50%) percent of the Share Consideration (the "Escrow Shares") was deposited in an escrow account as security for indemnification obligations and any purchase price adjustments due to working capital
deficiencies and any other claims or expenses. Under the Skypersonic Agreements, closing
date working capital deficits in excess of $&lt;span id="xdx_907_ecustom--WorkingCapitalDeficitMaximumAmountToResultInReductionOfShareConsiderationValue_iN_di_c20210501__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zRry4YK8Ixvg"&gt;300,000 &lt;/span&gt;shall
result in a reduction of the Share Consideration on a dollar of dollar basis.&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt; &lt;/span&gt;In
October 2021, the Company and Skypersonic agreed to a reduction in the purchase price of $&lt;span id="xdx_908_ecustom--ReductionInPurchasePriceFromWorkingCapitalDeficitOfAquiree_c20211001__20211031__us-gaap--BusinessAcquisitionAxis__custom--BusinessAcquisition4Member_zAxYLo424rCj"&gt;601,622&lt;/span&gt; which resulted in the cancellation
of 149,829 shares held in escrow. A &lt;span&gt;revised summary of the purchase price and its related allocation&lt;/span&gt; is as follows:&lt;/p&gt;

foregoing amounts reflect our current estimates of fair value as of the May 7, 2021 acquisition date. The Company expects to recognize
fair values associated with the customer relationships acquired, as well as the Skypersonic brand name, but has not yet accumulated sufficient
information to assign such values. As additional information becomes known regarding the acquired assets and assumed liabilities, management
may make adjustments to the opening balance sheet of the acquired company up to the end of the measurement period, which is a one-year
period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related
determination of estimated lives of depreciable tangible and intangible assets) requires significant judgment.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On August 31, 2021, the Company closed the acquisition
of Teal Drones Inc., (&#x201c;Teal&#x201d;). The acquisition of Teal was made pursuant to an Agreement and Plan of Merger by and among Red
Cat Holdings, Inc., a Nevada corporation (the &#x201c;Company&#x201d;), Teal Acquisition I Corp., a Delaware corporation (&#x201c;Acquisition&#x201d;)
and wholly-owned subsidiary of the Company, and Teal, as amended and restated August 31, 2021 (the &#x201c;Merger Agreement&#x201d; or &#x201c;Merger&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On August 31, 2021, Teal entered into an Amended and
Restated Loan and Security Agreement with Decathlon Alpha IV, L.P. (&#x201c;DA4&#x201d;) (the &#x201c;Loan Agreement&#x201d;) in the amount
of $1,670,294 (the &#x201c;Loan&#x201d;), representing the outstanding principal amount previously due and owing by Teal to DA4. Interest
on the Loan accrues at a rate of ten (10%) percent per annum. Principal and interest under the term Loan is payable monthly in an amount
equal to $49,275 until maturity on December 31, 2024.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Pursuant
to the Merger Agreement, we acquired all of the issued and outstanding share capital of Teal in exchange for $14,000,000 of our
common stock, par value $0.001 per share (&#x201c;Common Stock&#x201d;) at the Volume Weighted Average Price (VWAP) of our Common
Stock for the 20 trading days ended  August 31, 2021 of $2.908 per share, reduced by the amount of Teal debt assumed consisting of
approximately $1.67 million payable to DA4, and approximately $1,457,000 in working capital deficit, for a net closing date payment
of $10,872,753. At closing, we issued 3,738,911 shares of our Common Stock (the &#x201c;Stock Consideration&#x201d;) which had a fair
market value of $10,431,562. Fifteen (15%) of the Share Consideration (the &#x201c;Escrow Shares&#x201d;) was deposited in an escrow
account for a period of eighteen (18) months as security for indemnification obligations,  any purchase price adjustments due to
working capital deficiencies and any other claims or expenses. In December 2021, the Company and
Teal agreed to a reduction in the purchase price of $438,058 which resulted in the cancellation of 150,639 shares held in escrow.
The fair market value of the cancelled shares was $420,283. A &lt;span&gt;revised summary of the purchase price
and its related allocation&lt;/span&gt; is set forth below.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Stock Consideration payable under the Merger
Agreement may be increased upon the achievement of certain milestones set forth in the Merger Agreement (the &#x201c;Earn-Out Consideration&#x201d;).
Additional shares of Common Stock may become issuable by the Company in the event that within twenty-four (24) months following closing
of the Merger, Teal realizes certain revenue targets. A total of Sixteen Million Dollars ($16,000,000) in additional shares of Common
Stock will be issued if sales and services of Teal's Golden Eagle drones equal at least Thirty-six Million Dollars ($36,000,000).
A total of Ten Million Dollars ($10,000,000) in additional shares of Common Stock will be issued if sales and services of Teal's
Golden Eagle drones equal at least $24 million ($24,000,000) but less than $36 million ($36,000,000). A total of Four Million Dollars
($4,000,000) in additional shares of Common Stock will be issued if sales and services of Teal's Golden Eagle drones equal at least
Eighteen Million Dollars ($18,000,000) but less than Twenty-Four Million Dollars ($24,000,000). Additional Share Consideration, if earned,
is issuable at the VWAP of the Company within thirty (30) days of the determination that Earn-Out Consideration is payable.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The foregoing amounts reflect our current estimates
of fair value as of the August 31, 2021 acquisition date. The Company expects to recognize fair values associated with the customer relationships
acquired, as well as the Teal brand name, but has not yet accumulated sufficient information to assign such values. As additional information
becomes known regarding the acquired assets and assumed liabilities, management may make adjustments to the opening balance sheet of
the acquired company up to the end of the measurement period, which is a one-year period following the acquisition date. The determination
of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible
and intangible assets) requires significant judgment.&#160;&lt;/p&gt;

&lt;p id="xdx_849_eus-gaap--BasisOfAccountingPolicyPolicyTextBlock_z7Zi5d7QRbw2" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&lt;b&gt;&lt;span id="xdx_867_zGnJEgTtUCHh"&gt;Basis
of Accounting&lt;/span&gt;&lt;/b&gt; - The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted
in the United States ("GAAP").&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_85B_zsPpZQ1ZdoOh" style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_840_eus-gaap--ConsolidationPolicyTextBlock_zOMxgUUTXWL7" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&lt;b&gt;&lt;span id="xdx_869_zWVCKBTqNNa9"&gt;Principles
of Consolidation&lt;/span&gt;&lt;/b&gt; - Our condensed consolidated financial statements include the accounts of our operating subsidiaries,
Red Cat Propware, Inc., Rotor Riot, Fat Sharking Holdings, Skypersonic, and Teal Drones. Intercompany transactions and balances have been
eliminated.&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_85C_zUU1I22imlc3" style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_84F_eus-gaap--UseOfEstimates_zNOsIE2H7NM1" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="xdx_867_zPpPP0CnjIY9"&gt;&lt;b&gt;Use
of Estimates&lt;/b&gt;&lt;/span&gt; - The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Significant estimates reflected in these financial statements include those used to (i) determine stock based compensation, (ii) complete
purchase price accounting for acquisitions, and (iii) the accounting for derivatives.&lt;/p&gt;

&lt;p id="xdx_85F_zkVCg0UbFxkk" style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_84D_eus-gaap--CashAndCashEquivalentsPolicyTextBlock_zEVxRIiDZkRh" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&lt;b&gt;&lt;span id="xdx_863_zmFOhO7NVXij"&gt;Cash
and Cash Equivalents&lt;/span&gt; &lt;/b&gt;- At October 31, 2021, we had cash of $&lt;span id="xdx_905_eus-gaap--Cash_iI_c20211031_z4uFJRnoSgdc"&gt;11,559,758&lt;/span&gt;&#160;in multiple commercial banks and financial services companies.
We have not experienced any loss on these accounts and believe they are not exposed to any significant credit risk.&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_856_ztAMyTNvMIr3" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_84A_eus-gaap--InvestmentPolicyTextBlock_zEjvyjQJIwlf" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&lt;b&gt;&lt;span id="xdx_866_z29QKPQHy1Ok"&gt;Investments&lt;/span&gt;
&lt;/b&gt;&#x2013; Our investments have been classified and accounted for as available-for-sale securities. Our investment manager can sell
any of our investment holdings at any time, and therefore, we have classified our investments as short term. Our available-for-sale securities
are carried at fair value, with unrealized gains and losses reported within investment income in our consolidated statements of
operations.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;We
have elected to present accrued interest receivable separately from investments on our consolidated balance sheets. Accrued interest
receivable was $&lt;span id="xdx_900_eus-gaap--AccruedInvestmentIncomeReceivable_iI_c20211031_z2gwTAq6eii2"&gt;371,095&lt;/span&gt; as of October 31, 2021 and was recorded as other current assets. We did not write off any accrued interest receivable
during the three months ended October 31, 2021.&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_858_zdFagDphsar" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Receivable, net&lt;/span&gt;&lt;/b&gt; - Accounts receivable are recorded at the invoiced amount less allowances for doubtful accounts. The
Company's estimate of the allowance for doubtful accounts is based on a multitude of factors, including historical bad debt levels
for its customer base, past experience with a specific customer, the economic environment, and other factors. Accounts receivable
balances are written off against the allowance when it is probable that the receivable will not be collected.&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_85C_ztjNcH59r4Qg" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;


&lt;p id="xdx_843_eus-gaap--InventoryPolicyTextBlock_zoZdBqjbP42i" style="font: 12pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&lt;b&gt;&lt;span id="xdx_864_zhZ22DTKhlYd"&gt;Inventories&lt;/span&gt;&lt;/b&gt;&#160;&#x2013;&#160;Inventories,
which consist of raw materials, work-in-process, and finished goods, are stated at the lower of cost or net realizable value, with cost
being determined by the average-cost method, which approximates the first-in, first-out method. Cost components include direct materials
and direct labor, as well as in-bound freight. At each balance sheet date, the Company evaluates ending inventories for excess quantities
and obsolescence.&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_853_z4kOrOOSFmmi" style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_849_eus-gaap--GoodwillAndIntangibleAssetsGoodwillPolicy_zTTaKXRZtZ5" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&lt;b&gt;&lt;span id="xdx_863_zU3xXP5MMERe"&gt;Goodwill&lt;/span&gt;
&lt;/b&gt;- Goodwill represents the excess of the purchase price of an acquisition over the estimated fair value of identifiable net assets
acquired. The measurement periods for the valuation of assets acquired and liabilities assumed ends as soon as information on the facts
and circumstances that existed as of the acquisition date becomes known, not to exceed 12 months. Adjustments in a purchase price allocation
may require a change in the amounts allocated to goodwill during the periods in which the adjustments are determined.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;We
perform an impairment test at the end of each fiscal year, or more frequently if indications of impairment arise. We have a single reporting
unit, and consequently, evaluate goodwill for impairment based on an evaluation of the fair value of the Company as a whole.&lt;/span&gt;&#160;&lt;/p&gt;

&lt;p id="xdx_85D_zNS0OOyZqsy8" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"/&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p id="xdx_847_eus-gaap--RevenueRecognitionLeasesOperating_zFRvUjEPGbF8" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="xdx_86E_zvwkkJtMB3ea" style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&lt;b&gt;Leases
&lt;/b&gt;&lt;/span&gt;&lt;b&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;- &lt;/span&gt;&lt;/b&gt;Effective August 1,
2021, the Company adopted Accounting Standards Codification (ASC) 842 titled &#x201c;Leases&#x201d; which requires the recognition of assets
and liabilities associated with lease agreements. The Company adopted ASC 842 on a modified retrospective transition basis which
means that it will not restate financial information for any periods prior to August 1, 2021. Upon adoption, the Company recognized
a lease liability obligation of $796,976 and a right-of-use asset for the same amount.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; background-color: white"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"&gt;The Company determines if
a contract is a lease or contains a lease at inception.&#160; Operating lease liabilities are measured, on each reporting date, based
on the present value of the future minimum lease payments over the remaining lease term.&#160; The Company's leases do not provide an
implicit rate.&#160;Therefore, the Company uses an effective discount rate of 12% based on its recent debt financings.&#160;Operating
lease assets are measured by adjusting the lease liability for lease incentives, initial direct costs incurred and asset impairments.&#160;
Lease expense for minimum lease payments is recognized on a straight line basis over the lease term with the operating lease asset reduced
by the amount of the expense. Lease terms may include options to extend or terminate a lease when they are reasonably certain to occur.&lt;/p&gt;

Values, Inputs and Valuation Techniques for Financial Assets and Liabilities and Related Disclosures&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
fair value measurements and disclosure guidance defines fair value and establishes a framework for measuring fair value. Fair value is
defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date. In accordance with this guidance, the Company has categorized its recurring basis financial assets
and liabilities into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and
the lowest priority to unobservable inputs (Level 3). The inputs used to measure fair value may fall into different levels of the fair
value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has
been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment
of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific
to the asset or liability.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
levels of the fair value hierarchy are described below:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

    1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability
    to access.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

    2 inputs utilize other than quoted prices included in Level 1 that are observable for the asset, either directly or indirectly, for
    substantially the full term of the asset. Level 2 inputs include quoted prices for similar assets in active markets, quoted prices
    for identical or similar assets in markets that are not active and inputs other than quoted prices that are observable in the marketplace
    for the asset. The observable inputs are used in valuation models to calculate the fair value for the asset.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

    3 inputs are unobservable but are significant to the fair value measurement for the asset, and include situations where there is
    little, if any, market activity for the asset. These inputs reflect management's own assumptions about the assumptions a market participant
    would use in pricing the asset.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;A
review of fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may
result in a reclassification of levels for certain securities within the fair value hierarchy.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
Company's financial instruments mainly consist of cash, receivables, current assets, accounts payable and accrued expenses and debt.
The carrying amounts of its cash, receivables, current assets, accounts payable, accrued expenses and current debt approximates fair
value due to the short-term nature of these instruments.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Securities and Derivatives&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;When
the Company issues convertible debt or equity instruments that contain embedded derivative instruments that are to be bifurcated and
accounted for as liabilities, the total proceeds from the convertible host instruments are first allocated to the bifurcated derivative
instruments.&#160;&#160;The remaining proceeds, if any, are then allocated to the convertible instruments themselves, resulting in those
instruments being recorded at a discount from their face value but no lower than zero. Any excess amount is recognized as a derivative
expense.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Liabilities&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
Company has financial instruments that are considered derivatives or contain embedded features subject to derivative accounting. Embedded
derivatives are valued separately from the host instrument and are recognized as derivative liabilities in the Company's balance sheet.
The Company measures these instruments at their estimated fair value and recognizes changes in their estimated fair value in results
of operations during the period of change.&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;In
October 2020 and January 2021, the Company entered into convertible note agreements which included provisions under which the conversion
price was equal to the lesser of an initial stated amount or the conversion price of a future offering. This variable conversion feature
was recognized as a derivative. Both financings included the issuance of warrants which contained similar variable conversion features.
The Company values these convertible notes and warrants using the multinomial lattice method that values the derivative liability within

change in the liability is reflected as change in derivative liability in the statement of operations.&lt;/span&gt;&lt;/p&gt;

Recognition&lt;/span&gt; &lt;/b&gt;- The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers", issued
by the Financial Accounting Standards Board ("FASB"). This standard includes a comprehensive evaluation of factors to be considered
regarding revenue recognition including (i) identifying the promised goods, (ii) evaluating performance obligations, (iii) measuring
the transaction price, (iv) allocating the transaction price to the performance obligations if there are multiple components, and (v)
recognizing revenue as each obligation is satisfied.&#160; The Company's revenue transactions include a single component, specifically,
the shipment of goods to customers as orders are fulfilled. Customers pay at the time they order and the Company recognizes revenue upon
shipment. The timing of the shipment of orders can vary considerably depending upon whether an order is for an item normally maintained
in inventory or an order that requires assembly or unique parts. Customer deposits totaled $117,842 and&#160;$46,096 at October 31, 2021
and April 30, 2021, respectively.&lt;/span&gt;&lt;/p&gt;

and Development&lt;/span&gt; &lt;/b&gt;- Research and development expenses include payroll, employee benefits, and other headcount-related expenses associated
with product development. Research and development expenses also include third-party development and programming costs, as well as a
proportionate share of overhead costs such as rent. Costs related to software development are included in research and development expense
until technological feasibility is reached, which for our software products, is generally shortly before the products are released to
production. Once technological feasibility is reached, such costs are capitalized and amortized as a cost of revenue over the estimated
lives of the products.&lt;/span&gt;&lt;/p&gt;

Taxes&lt;/span&gt;&lt;/b&gt; - Deferred taxes are provided on the liability method, whereby deferred tax assets are recognized for deductible temporary
differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences
between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the
effects of changes in tax laws and rates on the date of enactment.&#160;&lt;/span&gt;&lt;/p&gt;

Compensation&lt;/span&gt; &lt;/b&gt;- We use the estimated grant-date fair value method of accounting in accordance with ASC Topic 718, Compensation - Stock
Compensation. Fair value is determined using the Black-Scholes Model using inputs reflecting our estimates of expected volatility, term
and future dividends. We recognize forfeitures as they occur. We recognize compensation costs on a straight line basis over the service
period which is generally the vesting term.&lt;/span&gt;&lt;/p&gt;

and Diluted Net Loss per Share&lt;/span&gt;&lt;/b&gt; - Basic and diluted net loss per share has been calculated by dividing net loss by the weighted average
number of shares of common stock outstanding during the period. Common stock equivalents were excluded from the computation of diluted
net loss per share of common stock because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings
per share if we become profitable in the future.&lt;/span&gt;&lt;/p&gt;

that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Significant estimates reflected in these financial statements include those used to (i) determine stock based compensation, (ii) complete

&lt;/b&gt;&#x2013; Our investments have been classified and accounted for as available-for-sale securities. Our investment manager can sell
any of our investment holdings at any time, and therefore, we have classified our investments as short term. Our available-for-sale securities

Receivable, net&lt;/span&gt;&lt;/b&gt; - Accounts receivable are recorded at the invoiced amount less allowances for doubtful accounts. The
Company's estimate of the allowance for doubtful accounts is based on a multitude of factors, including historical bad debt levels
for its customer base, past experience with a specific customer, the economic environment, and other factors. Accounts receivable
balances are written off against the allowance when it is probable that the receivable will not be collected.&lt;/span&gt;&lt;/p&gt;

&lt;/b&gt;- Goodwill represents the excess of the purchase price of an acquisition over the estimated fair value of identifiable net assets
acquired. The measurement periods for the valuation of assets acquired and liabilities assumed ends as soon as information on the facts
and circumstances that existed as of the acquisition date becomes known, not to exceed 12 months. Adjustments in a purchase price allocation

perform an impairment test at the end of each fiscal year, or more frequently if indications of impairment arise. We have a single reporting

2021, the Company adopted Accounting Standards Codification (ASC) 842 titled &#x201c;Leases&#x201d; which requires the recognition of assets
and liabilities associated with lease agreements. The Company adopted ASC 842 on a modified retrospective transition basis which
means that it will not restate financial information for any periods prior to August 1, 2021. Upon adoption, the Company recognized
a lease liability obligation of $796,976 and a right-of-use asset for the same amount.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; background-color: white"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"&gt;The Company determines if
a contract is a lease or contains a lease at inception.&#160; Operating lease liabilities are measured, on each reporting date, based
on the present value of the future minimum lease payments over the remaining lease term.&#160; The Company's leases do not provide an
implicit rate.&#160;Therefore, the Company uses an effective discount rate of 12% based on its recent debt financings.&#160;Operating
lease assets are measured by adjusting the lease liability for lease incentives, initial direct costs incurred and asset impairments.&#160;
Lease expense for minimum lease payments is recognized on a straight line basis over the lease term with the operating lease asset reduced
by the amount of the expense. Lease terms may include options to extend or terminate a lease when they are reasonably certain to occur.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
fair value measurements and disclosure guidance defines fair value and establishes a framework for measuring fair value. Fair value is
defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date. In accordance with this guidance, the Company has categorized its recurring basis financial assets
and liabilities into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and
the lowest priority to unobservable inputs (Level 3). The inputs used to measure fair value may fall into different levels of the fair
value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has
been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment
of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific
to the asset or liability.&lt;/span&gt;&lt;/p&gt;

the Company issues convertible debt or equity instruments that contain embedded derivative instruments that are to be bifurcated and
accounted for as liabilities, the total proceeds from the convertible host instruments are first allocated to the bifurcated derivative
instruments.&#160;&#160;The remaining proceeds, if any, are then allocated to the convertible instruments themselves, resulting in those
instruments being recorded at a discount from their face value but no lower than zero. Any excess amount is recognized as a derivative

Company has financial instruments that are considered derivatives or contain embedded features subject to derivative accounting. Embedded
derivatives are valued separately from the host instrument and are recognized as derivative liabilities in the Company's balance sheet.
The Company measures these instruments at their estimated fair value and recognizes changes in their estimated fair value in results
of operations during the period of change.&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

October 2020 and January 2021, the Company entered into convertible note agreements which included provisions under which the conversion
price was equal to the lesser of an initial stated amount or the conversion price of a future offering. This variable conversion feature
was recognized as a derivative. Both financings included the issuance of warrants which contained similar variable conversion features.
The Company values these convertible notes and warrants using the multinomial lattice method that values the derivative liability within
the notes based on a probability weighted discounted cash flow model. The resulting liability is valued at each reporting date and the
change in the liability is reflected as change in derivative liability in the statement of operations.&lt;/span&gt;&lt;/p&gt;

Recognition&lt;/span&gt; &lt;/b&gt;- The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers", issued
by the Financial Accounting Standards Board ("FASB"). This standard includes a comprehensive evaluation of factors to be considered
regarding revenue recognition including (i) identifying the promised goods, (ii) evaluating performance obligations, (iii) measuring
the transaction price, (iv) allocating the transaction price to the performance obligations if there are multiple components, and (v)
recognizing revenue as each obligation is satisfied.&#160; The Company's revenue transactions include a single component, specifically,
the shipment of goods to customers as orders are fulfilled. Customers pay at the time they order and the Company recognizes revenue upon
shipment. The timing of the shipment of orders can vary considerably depending upon whether an order is for an item normally maintained
in inventory or an order that requires assembly or unique parts. Customer deposits totaled $117,842 and&#160;$46,096 at October 31, 2021
and April 30, 2021, respectively.&lt;/span&gt;&lt;/p&gt;

net loss per share of common stock because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings

the amount of $&lt;span id="xdx_901_ecustom--SBAPPPLoanAmountsReceived_c20210201__20210202__us-gaap--DebtInstrumentAxis__custom--DebtObligation4Member_z8r4k8XbYr1j"&gt;300,910&lt;/span&gt;.
The loan is unsecured, non-recourse, and accrues interest at one percent annually. All or a portion of the loan is forgivable if
used to fund qualifying payroll, rent and utilities. If not forgiven, the loan is payable over five years. Teal used the proceeds
for the purposes required and the Company is currently working with the SBA regarding the loan forgiveness process.&lt;/span&gt;&lt;/p&gt;

Capital is an affiliate of Shopify, Inc. which provides sales software and services to the Company.&#160; The Company processes customer
transactions ordered on the e-commerce site for Rotor Riot through Shopify.&#160; Shopify Capital has entered into multiple agreements
with the Company in which it has "purchased receivables" at a discount.&#160; Shopify retains a portion of the Company's daily
receipts until the purchased receivables have been paid.&#160; The Company recognizes the discount as a transaction fee, in full, in
the month in which the agreement is executed.&#160; The Company assumed an existing agreement when it acquired Rotor Riot in January
2020.&#160; This agreement was repaid in May 2020.&#160; Since then, the Company has entered into the following &lt;span&gt;agreements with Shopify&lt;/span&gt;:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;Our
operating subsidiary, Red Cat Propware, Inc., is incorporated and based in Puerto Rico which is a commonwealth of the United States.
We are not subject to taxation by the United States as Puerto Rico has its own taxing authority which passed the Export Services Act,
also known as Act 20, in 2012. Under Act 20, eligible businesses are subject to a special corporate tax rate of 4%. Since inception,
we have incurred net losses in each year of operations. Our current provision for the reporting periods presented in these financial
statements consisted of a tax benefit against which we applied a full valuation allowance, resulting in no current provision for income
taxes. In addition, there was no deferred provision for any of these reporting periods.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/105% Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;At
October 31, 2021 and April 30, 2021, we had accumulated deficits of approximately $&lt;span id="xdx_90B_eus-gaap--RetainedEarningsAccumulatedDeficit_iI_dxL_c20211031_zZVNrSqjF6M6" title="::XDX::-20%2C108%2C301"&gt;&lt;span style="-sec-ix-hidden: xdx2ixbrl1144"&gt;20,100,000&lt;/span&gt;&lt;/span&gt; and $&lt;span id="xdx_90A_eus-gaap--RetainedEarningsAccumulatedDeficit_iI_dxL_c20210430_zwZnlObKRAAk" title="::XDX::-15%2C809%2C928"&gt;&lt;span style="-sec-ix-hidden: xdx2ixbrl1145"&gt;15,800,000&lt;/span&gt;&lt;/span&gt;, respectively. Deferred
tax assets related to the future benefit of these net operating losses for tax purposes totaled approximately $&lt;span id="xdx_904_eus-gaap--DeferredTaxAssetsOperatingLossCarryforwards_iI_c20211031_zEPS15W4cl03"&gt;804,000&lt;/span&gt; and $&lt;span id="xdx_90D_eus-gaap--DeferredTaxAssetsOperatingLossCarryforwards_iI_c20210430_zNjSJuIpQF9j"&gt;632,000&lt;/span&gt;,
respectively, based on the Act 20 rate of 4%. &#160;Currently, we focus on projected future taxable income in evaluating whether it is
more likely than not that these deferred assets will be realized. Based on the fact that we have not generated an operating profit since
inception, we have applied a full valuation allowance against our deferred tax assets at October 31, 2021 and April 30, 2021.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In May 2021, the Company issued warrants to purchase

the placement agent of its common stock offering. The warrants have a five year term and an exercise price of $&lt;span id="xdx_90C_ecustom--WarrantsIssuedExercisePrice_c20210501__20210531_zH31eKgvrQq6"&gt;5.00.&lt;/span&gt;&lt;/p&gt;

which had been issued in October 2020 as part of the convertible note financings described in Note 6. Since these exercises resulted
in the elimination of the derivative liability in the warrants, the derivative liability was reduced by $&lt;span id="xdx_90C_ecustom--ReductionInDerivativeLiabilityResultingFromExerciseOfWarrants_c20210601__20210630_zzmyO1hWJke7"&gt;163,141 &lt;/span&gt;&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;with

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;The
Company completed financings in October 2020 and January 2021 which included notes and warrants containing embedded features subject
to derivative accounting. See Note 10 for a full description of these financings. Both the notes and the warrants included provisions
which provided for a reduction in the conversion and exercise prices, respectively, if the Company completed a future qualified offering
at a lower price. These provisions represent embedded derivatives which are valued separately from the host instrument (meaning the notes
and warrants) and recognized as derivative liabilities on the Company's balance sheet. The Company initially measures these financial
instruments at their estimated fair value and recognizes changes in their estimated fair value in results of operations during the period
of change. The Company also measures these financial instruments on the date of settlement (meaning when the note is converted or the
warrant is exercised) at their estimated fair value and recognizes changes in their estimated fair value in results of operations. Any
discount in the carrying value of the note is fully amortized on the date of settlement and recognized as interest expense. The Company
estimated the fair value of these embedded derivatives using a multinomial lattice mode1. The range of underlying assumptions used in
the binomial model to determine the fair value of the derivative warrant liability upon settlement of the derivative liability and as
of October 31, 2021 are set forth below. In addition, the Company's stock price on each measurement date was used in the model.&#160;&lt;/span&gt;&#160;&lt;/p&gt;
