losses and cash burn for the foreseeable future, as well as recurring losses from operations, if the Company is unable to raise sufficient
capital through additional debt or equity arrangements, there will be uncertainty regarding the Company&#8217;s ability to maintain liquidity
sufficient to operate its business effectively, which raises substantial doubt as to the Company&#8217;s ability to continue as a going
concern within one year from the date of issuance of these condensed consolidated financial statements. The Company&#8217;s independent registered public
accounting firm, in its report on the Company&#8217;s consolidated financial statements for the year ended December 31, 2022, expressed
substantial doubt about the Company&#8217;s ability to continue as a going concern. These condensed consolidated financial statements
do not include any adjustments that might result from this uncertainty. There can be no assurance that such additional capital, whether
in the form of debt or equity financing, will be sufficient or available and, if available, that such capital will be offered on terms
and conditions acceptable to the Company. The Company&#8217;s primary focus is producing and selling its products. If the Company is unsuccessful
in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business
plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities. The Company believes that
its existing cash and cash equivalents as of September 30, 2023, plus expected receipts associated with product sales, will provide the
Company with liquidity to fund its planned operating needs into the first quarter of 2024.</p></ix:continuation>

market accounts, certificates of deposit, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all
highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original
maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments
with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate
classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company&#8217;s available-for-sale
investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income

are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to

or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction
price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or

at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for
transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly

following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was completed. Pursuant to
the completion of the Arrangement, each Peraso Share that was issued and outstanding immediately prior to December 17, 2021 was converted
into either newly issued shares of common stock of the Company or shares of Canco, which are exchangeable for shares of the Company&#8217;s
common stock (Exchangeable Shares), at the election of each former Peraso Tech stockholder. Of the shares issued to the holders of Peraso
Tech Shares, pursuant to the terms of the Agreement, the Company held in escrow an aggregate of <ix:nonFraction contextRef="c237" decimals="0" format="ixt:num-dot-decimal" name="prso:AggregateExchangeableShares" scale="0" unitRef="shares">1,312,878</ix:nonFraction> Exchangeable Shares and <ix:nonFraction contextRef="c238" decimals="0" format="ixt:num-dot-decimal" name="prso:ExchangeableSharesCommonStock" scale="0" unitRef="shares">502,567</ix:nonFraction>

on a pro rata basis from the aggregate consideration received by the holders of Peraso Shares, subject to the offset by the Company for
any losses in accordance with the Agreement. Such Escrow Shares shall be released, subject to any offset claim, upon the satisfaction
of the earlier of: (a) any date following the first anniversary of December 17, 2021 and prior to December 17, 2024 where the volume weighted
average price of the common stock for any 20 trading days within a period of 30 consecutive trading days is at least $<ix:nonFraction contextRef="c238" decimals="2" format="ixt:num-dot-decimal" name="us-gaap:SaleOfStockPricePerShare" scale="0" unitRef="usdPershares">8.57</ix:nonFraction> per share,

dividends and distributions, with respect to the Escrow Shares are suspended until the Escrow Shares are released from escrow.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Exchangeable Share structure is commonly used
for cross-border transactions of this nature so as to provide non-tax-exempt Canadian shareholders with the same economic rights and benefits
as holders of the Company&#8217;s shares into which the Exchangeable Shares are exchangeable, while allowing those Canadian shareholders
to benefit from the tax-rollover available on the issuance of the Exchangeable Shares. In general terms, by choosing to acquire Exchangeable
Shares from Canco, such a former Peraso Tech shareholder was able to rely on a rollover rule in the Income Tax Act (Canada) in order to
defer any capital gain that he/she/it would have otherwise realized.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Callco was incorporated to exercise the call rights,
while Canco was incorporated to acquire the shares of Peraso Tech from Canadian shareholders that wished to receive Exchangeable Shares
as consideration, so it was a tax deferred transaction for such Canadian shareholders. The use of a separate entity, Callco, helps maximize
cross border paid-up capital, which represents the amount that can generally be distributed free of Canadian withholding tax. The call
rights also allow Callco to &#8220;purchase&#8221; the Exchangeable Shares rather than having them redeemed by Canco on a redemption or
retraction or in connection with a liquidity event, thus avoiding the adverse deemed dividend tax consequences to shareholders that may
arise from a redemption or retraction of Exchangeable Shares.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Holders of Exchangeable Shares have the right

to the market price of a share of the Company&#8217;s common stock plus the full amount of all declared and unpaid dividends on such Exchangeable
Share (the Exchangeable Share Purchase Price). The Exchangeable Share Purchase Price is payable only by the Company delivering or causing
to be delivered to the relevant holder one share of the Company&#8217;s common stock for each Exchangeable Share purchased plus a cash
amount equal to the amount of any accrued and unpaid dividends on such Exchangeable Share. The Company and Callco each have an overriding
right, in the event that a holder of Exchangeable Shares exercises its Retraction Right, to redeem from such holder all, but not less
than all, of the Exchangeable Shares tendered for redemption.</p>

rights, as that is more beneficial to the holders of the Exchangeable Shares. Once Callco acquires the Exchangeable Shares from a holder,
it (Callco and the Company) is obligated to deliver the Company shares to the holder. Callco discharges this obligation by arranging for
the Company to issue and deliver those shares to the holders on behalf of Callco. As consideration for satisfying the delivery obligation,
Callco would issue its own shares to the Company.</p>

redemption and exchange scenarios are payable in a share of the Company&#8217;s common stock. Neither Canco, Callco, or the Company assume
any tax liabilities of a former Peraso Tech shareholder who acquired Exchangeable Shares under the plan of arrangement. The purchase price
computed upon the exercise of rights pertaining to retraction, redemption, or liquidation, or otherwise giving rise to a purchase or cancellation
of an Exchangeable Share, will, in all cases, consist of a 1:1 exchange involving the Company&#8217;s common stock, regardless of the
market price of a share of the Company&#8217;s common stock.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In connection with the Arrangement, on December
15, 2021, the Company filed the Certificate of Designation of Series A Special Voting Preferred Stock (the Certificate) with the Secretary
of State of the State of Delaware to designate Series A Special Voting Preferred Stock (the Special Voting Share) in accordance with the
terms of the Arrangement Agreement in order to enable the holders of Exchangeable Shares to exercise their voting rights. The Special
Voting Share was issued to a third-party administrative agent (the Agent) solely to facilitate the exercise of rights by holders of Exchangeable
Shares. The rights of the Agent, as holder of the Special Voting Share, are limited to effecting the rights of the holders of the Exchangeable
Shares; the Special Voting Share does not confer any independent rights to the Agent. Under the Certificate, when all of the Exchangeable
shares have been converted into shares of the Company&#8217;s common stock, the Special Voting Share shall be automatically cancelled
and shall not be reissued. Each Exchangeable Share is exchangeable for one share of common stock of the Company and while outstanding,
the Special Voting Share enables holders of Exchangeable Shares to cast votes on matters for which holders of the common stock are entitled
to vote, and by virtue of the share terms relating to the Exchangeable Shares, enable the Exchangeable Shares to receive dividends that
are economically equivalent to any dividends declared with respect to the shares of common stock. As the Special Voting Share does not
participate in dividends (only the Exchangeable Shares participate in dividends) and is not entitled to participate in the residual interest
of the Company, it is not classified as an equity instrument in the Company&#8217;s financial statements.</p>

into common stock at the option of the holder and have the same voting and dividend rights as common stock, are similar in substance to
shares of common stock. Further, Canco and Callco are non-substantive entities, which are looked through with the Exchangeable Shares
being, in substance, common stock of the Company. Therefore, the Exchangeable Shares have been included in the determination of outstanding

of common stock. Each pre-funded warrant was exercisable for one share of common stock. The purchase price of each pre-funded warrant
was $<ix:nonFraction contextRef="c252" decimals="2" format="ixt:num-dot-decimal" name="us-gaap:WarrantExercisePriceIncrease" scale="0" unitRef="usdPershares">0.99</ix:nonFraction>, and the exercise price of each pre-funded warrant was $<ix:nonFraction contextRef="c250" decimals="2" format="ixt:num-dot-decimal" name="us-gaap:WarrantExercisePriceIncrease" scale="0" unitRef="usdPershares">0.01</ix:nonFraction>&#160;per share. The pre-funded warrants were exercised in full
by the Investor in April 2023. Net proceeds to the Company from the registered direct offering, after offering costs, were approximately
$<ix:nonFraction contextRef="c249" decimals="-5" format="ixt:num-dot-decimal" name="us-gaap:DeferredOfferingCosts" scale="6" unitRef="usd">2.1</ix:nonFraction>&#160;million.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><span>In a concurrent

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; ">The 2023 Purchase Warrant
and the 2022 Purchase Warrant (collectively, the Purchase Warrants) provide for a value calculation using the Black Scholes model in the
event of certain fundamental transactions, as defined in the Purchase Warrants. The fair value calculation provides for a floor on the
volatility amount utilized in the value calculation at <ix:nonFraction contextRef="c0" decimals="2" format="ixt:num-dot-decimal" name="us-gaap:ShareBasedCompensationArrangementByShareBasedPaymentAwardFairValueAssumptionsExpectedVolatilityRateMaximum" scale="-2" unitRef="pure">100</ix:nonFraction>% or greater. The Company has determined that this provision introduces leverage
to the holder(s) of the Purchase Warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed
option on the Company&#8217;s own equity shares. Therefore, pursuant to ASC 815, the Company has classified the Purchase Warrants as liabilities
in its condensed consolidated balance sheets. The classification of the Purchase Warrants, including whether the Purchase Warrants should

formerly known as MoSys, Inc. (MoSys) and </span>were incorporated in California in 1991 and reincorporated in 2000 in Delaware. <span>On
September 14, 2021, we and our subsidiaries, 2864552 Ontario Inc. and 2864555 Ontario Inc., entered into an Arrangement Agreement (the
Arrangement Agreement) with Peraso Technologies Inc. (Peraso Tech), a corporation existing under the laws of the province of Ontario,
to acquire all of the issued and outstanding common shares of Peraso Tech (the Peraso Shares), including those Peraso Shares to be issued
in connection with the conversion or exchange of secured convertible debentures and common share purchase warrants of Peraso Tech, as
applicable, by way of a statutory plan of arrangement (the Arrangement) under the Business Corporations Act (Ontario).</span> On December
17, 2021, following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was completed <span>and
</span>we changed our name to &#8220;Peraso Inc.&#8221; and began trading on the Nasdaq Stock Market (the Nasdaq) under the symbol &#8220;PRSO.&#8221;</p><div>

and primary business objective is to be a profitable, IP-rich fabless semiconductor company offering integrated circuits, or ICs, antenna
modules and related non-recurring engineering services. We specialize in the development of mmWave semiconductors, primarily in the unlicensed
60 GHz spectrum band for 802.11ad/ay compliant devices and in the 28/39 GHz spectrum bands for 5G-compliant devices. We derive our revenue
from selling semiconductor devices, as well as antenna modules based on using those mmWave semiconductor devices. </span>We have pioneered
a high-volume mmWave production test methodology using standard low cost production test equipment. It has taken us several years to refine
performance of this production test methodology, and we believe this places us in a leadership position in addressing operational challenges
of delivering mmWave products into high-volume markets. The primary advantage provided by an antenna module is the silicon and the antenna
are integrated into a single device. A differentiating characteristic of mmWave technology is that the radio frequency amplifiers must
be as close as possible to the antenna to minimize loss, and by providing a module, we can guarantee the performance of the amplifier/antenna
interface.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><span>We also
acquired a memory product line marketed under the Accelerator Engine name. This memory product line comprises our Bandwidth Engine products,
which integrate our proprietary, 1T-SRAM high-density embedded memory and a highly-efficient serial interface protocol resulting in a
monolithic memory IC solution optimized for memory bandwidth and transaction access performance. Taiwan Semiconductor Manufacturing Corporation,
or TSMC, is the sole foundry that manufactures the wafers used to produce our memory IC products. TSMC recently informed us that it would
be discontinuing the foundry process used to produce wafers, in turn, necessary to manufacture our memory ICs. As a result, we have informed
our customers that we are initiating an end-of-life, or EOL, of our memory IC products. We have notified our customers to provide purchase
orders by December 22, 2023, and we commenced initial EOL shipments during the quarter ended September 30, 2023. We have requested customers
to pay a deposit upon purchase order placement to reserve supply and provide funding for our required inventory purchases. In addition,
we have requested customers to accelerate payments to improve our cash flows. Under our EOL plan, we expect shipments of our memory products
to continue until at least December 31, 2024. However, the timing of EOL shipments will be dependent on receipt of purchase orders from
customers, deliveries from our suppliers, and the delivery schedules requested by our customers.</span></p><div>

million for the nine months ended September 30, 2023 and $32.4 million for the year ended December 31, 2022, and we had an accumulated
deficit of&#160;approximately $157.5 million&#160;as of September 30, 2023. These and prior year losses have resulted in significant negative
cash flows and historically have required us to raise substantial amounts of additional capital. As discussed below, this raises significant
doubt about our ability to continue as a going concern. We will need to increase revenues substantially beyond levels that we have attained
in the past in order to generate sustainable operating profit and sufficient cash flows to continue doing business without raising additional
capital from time to time.</p><div>

to assist with the exploration of strategic alternatives, including a merger, sale of assets or other similar transaction, with the intention

in any strategic alternative, or as to its outcome or timing. We have neither set a timetable for completion of this process, nor have
we made any decisions related to strategic alternatives at this time. If a strategic process is unsuccessful and we are unable to raise
additional capital, we may be unable to continue our operations at planned levels and be forced to further reduce or terminate our operations.
These factors raise substantial doubt about our ability to continue as a going concern, as discussed below.</p><div>

2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020.
This negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation,
resulted in mandated closures and orders to &#8220;shelter-in- place&#8221; and created significant disruption of the financial markets.
While the U.S. national emergency expired in May 2023 and substantially all closures and &#8220;shelter-in-place&#8221; orders have ended,
there can be no assurance that the COVID-19 pandemic will not impact our operational and financial performance in the future, as the duration
and spread of the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread are uncertain,
out of our control, and cannot be predicted.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As a result of our expected operating losses and cash burn and recurring losses from operations, if we are unable to raise sufficient
capital through additional equity or debt arrangements, there will be uncertainty regarding our ability to maintain liquidity sufficient
to operate our business effectively, which raises substantial doubt as to our ability to continue as a going concern within one year from
the date of issuance of these condensed consolidated financial statements. The condensed consolidated financial statements presented in
Part I, Item 1 of this Report have been prepared assuming that we will continue as a going concern, and do not include any adjustments
that might result from the outcome of this uncertainty. There can be no assurance that such additional capital, whether in the form of
equity or debt financing, will be sufficient or available and, if available, that such capital will be offered on terms and conditions
acceptable to us. We are currently seeking additional financing in order to meet our cash requirements for the foreseeable future. If
the Company is unsuccessful in these efforts, it will need to implement additional cost reduction strategies, which could further affect
its near- and long-term business plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities.
In February 2023, we announced that we had implemented cost-reduction initiatives to reduce operating expenses by approximately $5 million
on an annualized basis. Most recently, in November 2023, we initiated a temporary lay-off in Canada of 16 positions, and eliminated three
full-time equivalent positions in the U.S. and Canada. We have the ability to recall the employees subject to temporary lay-off, however
such recalls would be dependent on improvements in business conditions and our financial condition, which we are unable to predict. If
we do not recall any of the affected employees in Canada, we would achieve annual total savings of approximately $2.8 million from these
reductions, excluding the impacts of any severance and related termination payments.</p><div>

offering of common stock and warrants for net proceeds to us of approximately $3.6 million. If we were to raise additional capital through
sales of our equity securities, our stockholders would suffer dilution of their equity ownership. If we engage in debt financing, we may
be required to accept terms that restrict our ability to incur additional indebtedness, prohibit us from paying dividends, repurchasing
our stock or making investments, and force us to maintain specified liquidity or other ratios, any of which could harm our business, operating
results and financial condition. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among other
things:</p><div>

the degree of compliance with the policies or procedures may deteriorate.</p><div>

the Securities Exchange Act of 1934. Based on this evaluation, our management concluded that, as of September 30, 2023, our disclosure

or TSMC, is the sole foundry that manufactures the wafers used to produce our memory IC products. TSMC has informed us that it will be
discontinuing the foundry process used to produce the wafers necessary to produce our memory ICs. We are not in a position to transition
wafer production to a new foundry and continue to manufacture these products. As a result, we have informed our customers that we are
initiating an end-of-life, or EOL, of our memory IC products. We expect to fulfill product EOL orders during 2024 and into 2025. Our memory
IC products represented over 50% of our revenues for the year ended December 31, 2022 and over 60% of our revenues for the nine months
ended September 30, 2023. The discontinuation of the production and sale of our memory IC products will negatively impact our future revenues,

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Our gross profit may fluctuate due to a number
of factors, including customer and product mix, market acceptance of our new products, yield, wafer pricing, packaging and testing costs,
competitive pricing dynamics, charges for inventory write-downs and geographic and market pricing strategies. To the extent we may offer
or be contractually obligated to offer certain customers favorable prices, it would decrease our average selling prices and likely impact
our gross profit. In the possible event our customers, including our larger customers, exert more pressure with respect to pricing and
other terms, it could put downward pressure on our profit.</p><div>

</div><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Because we do not operate our own wafer fabrication,
assembly, or testing facilities, we may not be able to reduce our costs as rapidly as companies that operate their own facilities, and
in fact, our costs may even increase, which could further reduce our gross profit. We seek yield improvements and volume-based cost reductions
to enable cost reductions. To the extent that such cost reductions do not occur at a sufficient level and in a timely manner, our business,
financial condition, and results of operations could be adversely affected and may vary from our estimates.</p><div>

inventories in anticipation of customer orders. If those customer purchase orders do not materialize in a timely manner or customers do
not honor those purchase orders, we can have excess or obsolete inventory which we would have to write-down, and our gross profit and
results of operations would be adversely affected.</p><div>

Price Rule&#8221;). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), we had a compliance period of 180 calendar days, or until July 31,
2023 (the &#8220;Compliance Period&#8221;) in which to regain compliance with the Minimum Bid Price Rule. We did not regain compliance
with the Minimum Bid Price Rule during the first 180-calendar-day Compliance Period and submitted a written request to Nasdaq to afford
us an additional 180-day compliance period to cure the deficiency. On August 1, 2023, we received written notification from the Listing
Qualifications Department of Nasdaq, granting our request for a 180-day extension to regain compliance with the Minimum Bid Price Rule.
We now have until January 29, 2024 to meet the requirement. If at any time prior to January 29, 2024, the bid price of our common stock
closes at $1.00 per share or more for a minimum of 10 consecutive business days, we will regain compliance with the Minimum Bid Price
Rule.</p><div>

Bid Price Rule during the additional 180-day extension, Nasdaq will provide written notification to us that our common stock will be delisted.
At that time, we may appeal the relevant delisting determination to a hearings panel pursuant to the procedures set forth in the applicable
Nasdaq Listing Rules. However, there can be no assurance that, if we do appeal the delisting determination by Nasdaq to the hearings panel,
that such appeal would be successful. Nor is there any assurance that we would obtain a further extension of time to meet this requirement.
We intend to actively monitor the closing bid price of our common stock and may, if appropriate, consider implementing available options
to regain compliance with the Minimum Bid Price Rule.</p><div>

time than we currently estimate and we may not be able to achieve the cost-efficiencies sought. In addition, the reduction in workforce
may negatively impact employee morale for those who are not directly impacted, which may increase employee attrition and hurt future recruiting

(the Company), formerly known as MoSys, Inc. (MoSys), </span>was incorporated in California in 1991 and reincorporated in 2000 in Delaware.
The Company is a fabless semiconductor company and derives revenue from selling its semiconductor devices and antenna modules, performance
of non-recurring engineering services and licensing of its technologies. The Company specializes in the development of millimeter wave
(mmWave), which is generally described as the frequency band from 24 Gigahertz (GHz) to 300GHz, wireless technology. In addition, the
Company also manufactures and sells high-performance memory semiconductor devices for a wide range of markets and receives royalties from
licensees of its memory technology.</p>

14, 2021, the Company and its subsidiaries, 2864552 Ontario Inc. (Callco) and 2864555 Ontario Inc. (Canco), entered into an Arrangement
Agreement (the Arrangement Agreement) with Peraso Technologies Inc. (Peraso Tech), a corporation existing under the laws of the province
of Ontario, to acquire all of the issued and outstanding common shares of Peraso Tech (the Peraso Shares), including those Peraso Shares
to be issued in connection with the conversion or exchange of secured convertible debentures and common share purchase warrants of Peraso
Tech, as applicable, by way of a statutory plan of arrangement (the Arrangement) under the Business Corporations Act (Ontario).</span>
On December 17, 2021, following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was
completed and<span>, </span>the Company changed its name to &#8220;Peraso Inc.&#8221; and began trading
on the Nasdaq Stock Market (the Nasdaq) under the symbol &#8220;PRSO.&#8221; <span>For accounting purposes,
Peraso Tech, the legal subsidiary, was treated as the accounting acquirer and the Company, the legal parent, was treated as the accounting
acquiree. The transaction was accounted for as a reverse acquisition in accordance with Financial Accounting Standards Board (FASB) Accounting
Standards Codification (ASC) 805, <i>Business Combinations</i></span>.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The accompanying condensed consolidated financial
statements of the Company have been prepared without audit. The condensed consolidated balance sheet as of December 31, 2022 has been
derived from the audited consolidated financial statements at that date. Certain information and disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted
in accordance with the rules&#160;and regulations of the Securities and Exchange Commission (SEC). The information in this report should
be read in conjunction with the Company&#8217;s consolidated financial statements and notes thereto included in its most recent annual
report on Form&#160;10-K filed with the SEC.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In the opinion of management, the accompanying
unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary
to summarize fairly the Company&#8217;s financial position, results of operations and cash flows for the interim periods presented. The
operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected
for the year ending December 31, 2023 or for any other future period.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><b><i>&#160;</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company incurred net losses of approximately
$7.9 million for the nine months ended September 30, 2023 and $32.4 million for the year ended December 31, 2022 and had an accumulated
deficit of approximately $157.5 million as of September 30, 2023. These and prior year losses have resulted in significant negative cash
flows and have required the Company to raise substantial amounts of additional capital. To date, the Company has primarily financed its
operations through offerings of equity and equity-linked securities, issuance of convertible notes and loans.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company expects to continue to incur operating
losses for the foreseeable future as it secures new customers for and continues to invest in the development of its products. Further,
the Company expects its cash expenditures to continue to exceed receipts for the foreseeable future, as its revenues will not be sufficient
to offset its operating expenses.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company will need to increase revenues substantially
beyond levels that it has attained in the past in order to generate sustainable operating profit and sufficient cash flows to continue
doing business without raising additional capital from time to time.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As a result of the Company&#8217;s expected operating
losses and cash burn for the foreseeable future, as well as recurring losses from operations, if the Company is unable to raise sufficient
capital through additional debt or equity arrangements, there will be uncertainty regarding the Company&#8217;s ability to maintain liquidity
sufficient to operate its business effectively, which raises substantial doubt as to the Company&#8217;s ability to continue as a going
concern within one year from the date of issuance of these condensed consolidated financial statements. The Company&#8217;s independent registered public
accounting firm, in its report on the Company&#8217;s consolidated financial statements for the year ended December 31, 2022, expressed
substantial doubt about the Company&#8217;s ability to continue as a going concern. These condensed consolidated financial statements
do not include any adjustments that might result from this uncertainty. There can be no assurance that such additional capital, whether
in the form of debt or equity financing, will be sufficient or available and, if available, that such capital will be offered on terms
and conditions acceptable to the Company. The Company&#8217;s primary focus is producing and selling its products. If the Company is unsuccessful
in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business
plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities. The Company believes that
its existing cash and cash equivalents as of September 30, 2023, plus expected receipts associated with product sales, will provide the
Company with liquidity to fund its planned operating needs into the first quarter of 2024.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The condensed consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been
eliminated in consolidation. The Company&#8217;s fiscal year ends on December 31 of each calendar year. Certain prior year amounts have
been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results
of operations or cash flows.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The global outbreak of the coronavirus disease
2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020.&#160;&#160;This
negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted
in mandated closures and orders to &#8220;shelter-in-place&#8221; and created significant disruption of the financial markets. While the
U.S. national emergency expired in May 2023 and substantially all closures and &#8220;shelter-in-place&#8221; orders have ended, there
can be no assurance that the COVID-19 pandemic will not impact the Company&#8217;s operational and financial performance in the future,
as the duration and spread of the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread
are uncertain, out of the Company&#8217;s control, and cannot be predicted.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">World unrest due to wars and terrorist attacks
have led to further economic disruptions. Mounting inflationary cost pressures and recessionary fears have negatively impacted the global
economy. Since mid-2022, the U.S. Federal Reserve has addressed elevated inflation by increasing interest rates, as inflation remains

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">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 revenues and expenses recognized
during the reported period. Material estimates may include assumptions made in determining reserves for uncollectible receivables, inventory
write-downs, impairment of long-term assets, valuation allowance on deferred tax assets, accruals for potential liabilities and assumptions
made in valuing equity instruments. Actual results could differ from those estimates.</p>

market accounts, certificates of deposit, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all
highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original
maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments
with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate
classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company&#8217;s available-for-sale
investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income
(loss). Realized gains and losses and declines in the value judged to be other-than-temporary are included in the other income, net line
item in the condensed consolidated statements of operations. The cost of securities sold is based on the specific identification method.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in">Level&#160;1&#8212;Inputs used to measure fair value are

of market information obtained through the Company&#8217;s investment advisors, rather than models. The Company does not adjust for, or
apply, any additional assumptions or estimates to the pricing information it receives from advisors. The Company&#8217;s Level&#160;2
securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, corporate
debt, and government agency and municipal debt securities from issuers with high-quality credit ratings. The Company&#8217;s investment
advisors obtain pricing data from independent sources, such as Standard&#160;&amp; Poor&#8217;s, Bloomberg and Interactive Data Corporation,
and rely on comparable pricing of other securities because the Level&#160;2 securities are not actively traded and have fewer observable
transactions. The Company considers this the most reliable information available for the valuation of the securities.</p>

by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are
generally determined using pricing models for which the assumptions utilize management&#8217;s estimates of market participant assumptions.
The determination of fair value for Level&#160;3 investments and other financial instruments involves the most management judgment and
subjectivity.</p>

such as cash and cash equivalents, accounts receivable, accounts payable, and other payables, approximate their fair values because of
the short maturity of these instruments. The carrying values of lease obligations and long-term financing obligations approximate their

of its warrant liabilities using Level 3 inputs.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b><i>&#160;</i></b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span><b><i>Derivatives

accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer
credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers.
A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances
are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers
deemed creditworthy in the judgment of management. The allowance for doubtful accounts receivable was approximately $30,000 as of September
30, 2023 and approximately $183,000 as of December 31, 2022.</p>

of cost, which approximates actual cost on a first-in, first-out basis, or net realizable value. Costs of inventories primarily consisted
of material and third party assembly costs. The Company records inventory reserves for estimated obsolescence or unmarketable inventories
based upon assumptions about future demand and market conditions. Once a reserve is established, it is maintained until the product to
which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional
adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis
of specific identification of obsolete inventory items and quantification of slow moving inventory items. The Company determined that
it had excess and obsolete inventory, primarily related to its mmWave products, and recorded write-downs of inventory of approximately
$793,000 and $420,000 during the nine months ended September 30, 2023 and 2022, respectively. If the Company&#8217;s recognition of excess
or obsolete inventory is, or if its estimates of inventory&#8217;s potential utility become, less favorable than currently expected, additional
inventory write-downs may be required.</p>

value of the customer relationships was determined by discounting estimated net future cash flows from the customer relationships. The
Company has revised the amortization period to conclude on December 31, 2024, as a result of the end-of-life announcement on May 1, 2023

has not identified any intangible asset impairments. However, current macroeconomic conditions, which have been impacted by inflation

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company recognizes revenue in accordance with
ASC Topic 606, <i>Revenue from Contracts with Customers</i>, and its amendments (ASC 606). As described below, the analysis of contracts
under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent
with the Company&#8217;s historical practice of recognizing product revenue when title and risk of loss pass to the customer.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company generates revenue primarily from sales
of integrated circuits and antenna module products, performance of engineering services and licensing of its intellectual property. Revenues
are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to
receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract,
or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction
price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or
as a performance obligation is satisfied.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Revenue is recognized when performance obligations
under the terms of a contract with a customer are satisfied. The majority of the Company&#8217;s contracts have a single performance obligation
to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally
at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for
transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly
to customers and through distributors generally under agreements with payment terms typically 60 days or less.</p>

provide for royalties based on the licensee&#8217;s use of the Company&#8217;s memory technology in its currently shipping commercial
products. The Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments
are received in the subsequent quarter. The Company also generates revenue from licensing its technology. The Company recognizes license
fees as revenue at the point of time when the control of the license has been transferred and the Company has no continuing performance
obligations to the customer.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Engineering services revenue </i></p>

the cost of net revenue of $600,000 associated with these shipments, and the amount deferred was presented as deferred cost of net revenue
in the condensed consolidated balance sheets. During the three months ended March 31, 2023, the Company recognized the associated revenue

liabilities were in a current position and included in deferred revenue.</p>

and restricted stock units to employees and non-employees. The Company accounts for such awards based on ASC 505 and ASC 718, whereby
the value of the award is measured on the date of award and recognized as compensation expense on a straight-line basis over the vesting
period. The fair value of the Company&#8217;s stock options is estimated using the Black-Scholes-Merton Option Pricing (Black Scholes)
model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the options, and future
dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes model. The assumptions used in the Black-Scholes

rate on the date of the transaction. All monetary assets and liabilities are remeasured at the end of each reporting period using the
exchange rate at that date. All non-monetary assets and related expense, depreciation or amortization are not subsequently remeasured
and are measured using the historical exchange rate. An average exchange rate may be used to recognize income and expense items earned
or incurred evenly over a period. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized
in the statement of operations, except for the gains and losses arising from the conversion of the carrying amount of the foreign currency
denominated convertible preferred shares into the functional currency that are presented as adjustment to the net loss to arrive at net
loss attributable to common stockholders.</p>

net loss for the period by the weighted-average number of exchangeable shares and shares of common stock outstanding during the period.
In addition, the Company includes the number of shares of common stock issuable under pre-funded warrants as outstanding. Diluted net
loss per share gives effect to all potentially dilutive exchangeable and common shares outstanding during the period. Potentially dilutive

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In 2010, the Company adopted the 2010 Equity Incentive
Plan and later amended it in 2014, 2017 and 2018 (the Amended 2010 Plan). The Amended 2010 Plan was terminated in August 2019 and remains
in effect as to outstanding equity awards granted prior to the date of expiration. No new awards may be made under the Amended 2010 Plan.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In August 2019, the Company&#8217;s stockholders
approved the 2019 Stock Incentive Plan (the 2019 Plan) to replace the Amended 2010 Plan. The 2019 Plan authorizes the board of directors
or the compensation committee of the board of directors to grant a broad range of awards including stock options, stock appreciation rights,
restricted stock, performance-based awards, and restricted stock units. Under the 2019 Plan, 182,500 shares were initially reserved for
issuance. In November 2021, in connection with the approval of the Arrangement, the Company&#8217;s stockholders approved an amendment
increasing the number of shares reserved for issuance under the 2019 Plan by 3,106,937 shares.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Under the 2019 Plan, the term of all incentive
stock options granted to a person who, at the time of grant, owns stock representing more than 10% of the voting power of all classes
of the Company&#8217;s stock may not exceed five years. The exercise price of stock options granted under the 2019 Plan must be at least
equal to the fair market value of the shares on the date of grant. Generally, awards under the 2019 Plan will vest over a three to four-year
period, and options will have a term of 10 years from the date of grant. In addition, the 2019 Plan provides for automatic acceleration
of vesting for options granted to non-employee directors upon a change of control of the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In connection with the Arrangement, the Company
assumed the Peraso Technologies Inc. 2009 Share Option Plan (the 2009 Plan) and all outstanding options granted pursuant to the terms
of the 2009 Plan. Each outstanding, unexercised and unexpired option under the 2009 Plan, whether vested or unvested, was assumed by the
Company and converted into options to purchase shares of the Company&#8217;s common stock No further awards will be made under the 2009
Plan.&#160;&#160;</p>

million and $3.4 million related to the vesting of stock options during each of the nine-month periods ended September 30, 2023 and 2022,
respectively. At September 30, 2023, the unamortized compensation cost was approximately $4.4 million related to stock options and is
expected to be recognized as expense over a weighted average period of approximately 1.2 years. The Company reflected compensation costs
of $0.8 million and $1.0 million related to the vesting of restricted stock during the nine months ended September 30, 2023 and 2022,
respectively. The unamortized compensation cost at September 30, 2023 was $1.3 million related to restricted stock units and is expected
to be recognized as expense over a weighted average period of approximately 1.3 years. There were no stock options granted or exercised
during the nine months ended September 30, 2023 and 2022.&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As discussed in Note 1, on December 17, 2021,
following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was completed. Pursuant to
the completion of the Arrangement, each Peraso Share that was issued and outstanding immediately prior to December 17, 2021 was converted
into either newly issued shares of common stock of the Company or shares of Canco, which are exchangeable for shares of the Company&#8217;s
common stock (Exchangeable Shares), at the election of each former Peraso Tech stockholder. Of the shares issued to the holders of Peraso
Tech Shares, pursuant to the terms of the Agreement, the Company held in escrow an aggregate of 1,312,878 Exchangeable Shares and 502,567
shares of common stock (collectively, the Escrow Shares). The Escrow Shares are escrowed pursuant to the terms of an escrow agreement
on a pro rata basis from the aggregate consideration received by the holders of Peraso Shares, subject to the offset by the Company for
any losses in accordance with the Agreement. Such Escrow Shares shall be released, subject to any offset claim, upon the satisfaction
of the earlier of: (a) any date following the first anniversary of December 17, 2021 and prior to December 17, 2024 where the volume weighted
average price of the common stock for any 20 trading days within a period of 30 consecutive trading days is at least $8.57 per share,
subject to adjustment for stock splits or other similar transactions; (b) the date of any sale of all or substantially all of the assets
or shares of the Company; or (c) the date of any bankruptcy, insolvency, restructuring, receivership, administration, wind-up, liquidation,
dissolution, or similar event involving the Company. All and any voting rights and other stockholder rights, other than with respect to
dividends and distributions, with respect to the Escrow Shares are suspended until the Escrow Shares are released from escrow.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"><b><i>&#160;</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Exchangeable Share structure is commonly used
for cross-border transactions of this nature so as to provide non-tax-exempt Canadian shareholders with the same economic rights and benefits
as holders of the Company&#8217;s shares into which the Exchangeable Shares are exchangeable, while allowing those Canadian shareholders
to benefit from the tax-rollover available on the issuance of the Exchangeable Shares. In general terms, by choosing to acquire Exchangeable
Shares from Canco, such a former Peraso Tech shareholder was able to rely on a rollover rule in the Income Tax Act (Canada) in order to
defer any capital gain that he/she/it would have otherwise realized.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Callco was incorporated to exercise the call rights,
while Canco was incorporated to acquire the shares of Peraso Tech from Canadian shareholders that wished to receive Exchangeable Shares
as consideration, so it was a tax deferred transaction for such Canadian shareholders. The use of a separate entity, Callco, helps maximize
cross border paid-up capital, which represents the amount that can generally be distributed free of Canadian withholding tax. The call
rights also allow Callco to &#8220;purchase&#8221; the Exchangeable Shares rather than having them redeemed by Canco on a redemption or
retraction or in connection with a liquidity event, thus avoiding the adverse deemed dividend tax consequences to shareholders that may
arise from a redemption or retraction of Exchangeable Shares.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Holders of Exchangeable Shares have the right
at any time (the Retraction Right) to retract or redeem any or all of the Exchangeable Shares owned by them for an amount per share equal
to the market price of a share of the Company&#8217;s common stock plus the full amount of all declared and unpaid dividends on such Exchangeable
Share (the Exchangeable Share Purchase Price). The Exchangeable Share Purchase Price is payable only by the Company delivering or causing
to be delivered to the relevant holder one share of the Company&#8217;s common stock for each Exchangeable Share purchased plus a cash
amount equal to the amount of any accrued and unpaid dividends on such Exchangeable Share. The Company and Callco each have an overriding
right, in the event that a holder of Exchangeable Shares exercises its Retraction Right, to redeem from such holder all, but not less
than all, of the Exchangeable Shares tendered for redemption.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Exchangeable Shares are subject to redemption
by the Company, Callco and Canco at the Exchangeable Share Purchase Price, on the &#8220;Redemption Date,&#8221; which date shall be no
earlier than the seventh anniversary of the date on which Exchangeable Shares are first issued, unless: (a) less than 10% of the aggregate
number of Exchangeable Shares issued remain outstanding; (b) there is a change in control of the Company (defined generally as (i) any
merger, amalgamation, arrangement, takeover bid or tender offer, material sale of shares or rights or interests that results in the holders
of outstanding voting securities of the Company directly or indirectly owning, or exercising control or direction over, voting securities
representing less than 50% of the total voting power of all of the voting securities of the surviving entity; or (ii) any sale or disposition
of all or substantially of the Company&#8217;s assets), and (c) upon the occurrence of certain other events. The Exchangeable Share Purchase
Price is payable only by the Company delivering or causing to be delivered to the relevant holder one share of the Company&#8217;s common
stock for each Exchangeable Share purchased plus a cash amount equal to the amount of any accrued and unpaid dividends on such Exchangeable
Share.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In the event of the liquidation, dissolution or
winding-up of Canco, holders of Exchangeable Shares have the right to receive in respect of each Exchangeable Share held by such holder,
an amount per share equal to the Exchangeable Share Purchase Price, which shall be satisfied in full by Canco by delivering to such holder
one Company Share, plus an amount equal to the Dividend Amount. The Company and Callco each have an overriding right to purchase from
all holders all but not less than all of the Exchangeable Shares upon the occurrence of such events.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In addition, the Company and Callco have the right
to purchase all outstanding Exchangeable Shares at the Exchangeable Share Purchase Price if there is a change of law that permits holders
of Exchangeable Shares to exchange their Exchangeable Shares for shares of common stock on a basis that will not require holders to recognize
any gain or loss or any actual or deemed dividend for Canadian tax purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The holders of Exchangeable Shares have an &#8220;automatic
exchange right&#8221; in the event of any insolvency, liquidation, dissolution or winding-up or in general, related proceedings, of the
Company for an amount per share equal to the Exchangeable Share Purchase Price.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">It is expected that Callco will exercise its call
rights, as that is more beneficial to the holders of the Exchangeable Shares. Once Callco acquires the Exchangeable Shares from a holder,
it (Callco and the Company) is obligated to deliver the Company shares to the holder. Callco discharges this obligation by arranging for
the Company to issue and deliver those shares to the holders on behalf of Callco. As consideration for satisfying the delivery obligation,
Callco would issue its own shares to the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">There are no cash redemption features, as all
redemption and exchange scenarios are payable in a share of the Company&#8217;s common stock. Neither Canco, Callco, or the Company assume
any tax liabilities of a former Peraso Tech shareholder who acquired Exchangeable Shares under the plan of arrangement. The purchase price
computed upon the exercise of rights pertaining to retraction, redemption, or liquidation, or otherwise giving rise to a purchase or cancellation
of an Exchangeable Share, will, in all cases, consist of a 1:1 exchange involving the Company&#8217;s common stock, regardless of the
market price of a share of the Company&#8217;s common stock.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">In connection with the Arrangement, on December
15, 2021, the Company filed the Certificate of Designation of Series A Special Voting Preferred Stock (the Certificate) with the Secretary
of State of the State of Delaware to designate Series A Special Voting Preferred Stock (the Special Voting Share) in accordance with the
terms of the Arrangement Agreement in order to enable the holders of Exchangeable Shares to exercise their voting rights. The Special
Voting Share was issued to a third-party administrative agent (the Agent) solely to facilitate the exercise of rights by holders of Exchangeable
Shares. The rights of the Agent, as holder of the Special Voting Share, are limited to effecting the rights of the holders of the Exchangeable
Shares; the Special Voting Share does not confer any independent rights to the Agent. Under the Certificate, when all of the Exchangeable
shares have been converted into shares of the Company&#8217;s common stock, the Special Voting Share shall be automatically cancelled
and shall not be reissued. Each Exchangeable Share is exchangeable for one share of common stock of the Company and while outstanding,
the Special Voting Share enables holders of Exchangeable Shares to cast votes on matters for which holders of the common stock are entitled
to vote, and by virtue of the share terms relating to the Exchangeable Shares, enable the Exchangeable Shares to receive dividends that
are economically equivalent to any dividends declared with respect to the shares of common stock. As the Special Voting Share does not
participate in dividends (only the Exchangeable Shares participate in dividends) and is not entitled to participate in the residual interest
of the Company, it is not classified as an equity instrument in the Company&#8217;s financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Exchangeable Shares, which can be converted
into common stock at the option of the holder and have the same voting and dividend rights as common stock, are similar in substance to
shares of common stock. Further, Canco and Callco are non-substantive entities, which are looked through with the Exchangeable Shares
being, in substance, common stock of the Company. Therefore, the Exchangeable Shares have been included in the determination of outstanding
common stock. The Special Voting Share was issued to a third-party administrative agent (the Agent) solely to facilitate the exercise
of rights by holders of Exchangeable Shares, The rights of the Agent, as holder of the Special Voting Share, are limited to effecting
the rights of the holders of the Exchangeable Shares; the Special Voting Share does not confer any independent rights to the Agent. Under
the Certificate, when all of the Exchangeable shares have been converted into shares of the Company&#8217;s common stock, the Special
Voting Share shall be automatically cancelled and shall not be reissued.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><b><i>June 2023 Registered Direct Offering</i></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">On May 31, 2023, the Company entered into a securities
purchase agreement (the SPA) with an institutional investor (the Investor), pursuant to which the Company sold to the Investor, in a registered
direct offering that closed on June 2, 2023, an aggregate of 2,250,000 shares of common stock at a purchase price of $0.70 per share.
Net proceeds to the Company from the registered direct offering, after offering costs, were approximately $3.6 million. The Company also
offered and sold to the Investor pre-funded warrants to purchase up to 3,464,286 shares of common stock (the 2023 PF Warrants). Each pre-funded
warrant is exercisable for one share of common stock. The purchase price of each pre-funded warrant was $0.69, and the exercise price
of each pre-funded warrant is $0.01 per share. The 2023 PF Warrants were immediately exercisable and may be exercised at any time until
all of such pre-funded warrants are exercised in full. In June 2023, the Investor exercised 967,286 of the 2023 PF Warrants, and in September
2023, the remaining 2,497,000 of the 2023 PF <span>Warrants were exercised by the Investor</span>. In
connection with the execution of the SPA, the Company and the Investor entered into an amendment (the Amendment) to the 2022 Purchase
Warrant. Pursuant to the terms of the Amendment, the 2022 Purchase Warrant (as defined below) was amended to reduce the exercise price
per share from $1.36 to $1.00, effective as of June 2, 2023.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; ">The 2023 Purchase Warrant
and the 2022 Purchase Warrant (collectively, the Purchase Warrants) provide for a value calculation using the Black Scholes model in the
event of certain fundamental transactions, as defined in the Purchase Warrants. The fair value calculation provides for a floor on the
volatility amount utilized in the value calculation at 100% or greater. The Company has determined that this provision introduces leverage
to the holder(s) of the Purchase Warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed
option on the Company&#8217;s own equity shares. Therefore, pursuant to ASC 815, the Company has classified the Purchase Warrants as liabilities
in its condensed consolidated balance sheets. The classification of the Purchase Warrants, including whether the Purchase Warrants should
be recorded as liabilities or as equity, is evaluated at the end of each reporting period with changes in the fair value reported in other
income (expense) in the condensed consolidated statements of operations and comprehensive loss.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; ">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; ">On June 2, 2023, the
2023 Purchase Warrant was initially recorded at a fair value at $3,162,401, and, as of September 30, 2023, the fair value of the warrant
liability was reduced to $634,828. As a result, the Company recorded a gain $2,527,572 for the nine months ended September 30, 2023 for
the change in fair value of the 2023 Purchase Warrant. The Company also recorded a gain of $1,711,527 for the nine months ended September
30, 2023 for the change in the fair value of the warrant liability for the 2022 Purchase Warrant.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; ">The fair value of the
Purchase Warrants at September 30, 2023 was determined using the Black Scholes model with the following assumptions: (i) expected term
based on the remaining contractual terms, (ii) risk-free interest rate of 4.16%, which was based on a comparable US Treasury 5-year bond,
(iii) expected volatility of 118% and (iv) an expected dividend of zero.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">On August 5, 2022, the Company entered into a
Technology License and Patent Assignment Agreement (the Intel Agreement) with Intel Corporation (Intel), pursuant to which Intel: (i)
licensed from the Company, on an exclusive basis, certain software and technology assets related to the Company&#8217;s Stellar packet
classification intellectual property, including its graph memory engine technology, and any roadmap variant, in the form existing as of
the date of the Agreement (the Licensed Technology); (ii) acquired from the Company certain patent applications and patents owned by the
Company; and (iii) assumed a professional services agreement, dated March 24, 2020, between Fabulous Inventions AB (Fabulous) and the
Company (the Fabulous Agreement), pursuant to which, among other things, the Company licensed from Fabulous certain technology incorporated
into the Licensed Technology.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As consideration for the Company to enter into
the Agreement, Intel agreed to pay the Company $3,062,500 at the closing of the transaction (the Closing) and $437,500 (the Holdback)
upon the satisfaction by the Company, as mutually agreed upon by the parties in good faith, of certain release criteria set forth in the
Agreement relating to various due diligence activities of Intel regarding the Licensed Technology (the Release Criteria).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company determined that the license and asset
sale did not qualify as a sale of a business, but as a sale of a non-financial asset, with the resultant gain recorded as income from
operations in accordance with ASC 610-20, <i>Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets</i>. During
the year ended December 31, 2022, the Company recognized a $2.6 million gain on this transaction, net of transaction costs. During the
nine months ended September 30, 2023, Intel paid the Holdback, and the Company recognized a $0.4 million gain, net of transaction costs,
which was recorded as a reduction of operating expenses in the condensed consolidated statements of operations and comprehensive loss.</p><span></span>

$7.9 million for the nine months ended September 30, 2023 and $32.4 million for the year ended December 31, 2022 and had an accumulated
deficit of approximately $157.5 million as of September 30, 2023. These and prior year losses have resulted in significant negative cash
flows and have required the Company to raise substantial amounts of additional capital. To date, the Company has primarily financed its
operations through offerings of equity and equity-linked securities, issuance of convertible notes and loans.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company expects to continue to incur operating
losses for the foreseeable future as it secures new customers for and continues to invest in the development of its products. Further,
the Company expects its cash expenditures to continue to exceed receipts for the foreseeable future, as its revenues will not be sufficient
to offset its operating expenses.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company will need to increase revenues substantially
beyond levels that it has attained in the past in order to generate sustainable operating profit and sufficient cash flows to continue
doing business without raising additional capital from time to time.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As a result of the Company&#8217;s expected operating
losses and cash burn for the foreseeable future, as well as recurring losses from operations, if the Company is unable to raise sufficient
capital through additional debt or equity arrangements, there will be uncertainty regarding the Company&#8217;s ability to maintain liquidity
sufficient to operate its business effectively, which raises substantial doubt as to the Company&#8217;s ability to continue as a going
concern within one year from the date of issuance of these condensed consolidated financial statements. The Company&#8217;s independent registered public
accounting firm, in its report on the Company&#8217;s consolidated financial statements for the year ended December 31, 2022, expressed
substantial doubt about the Company&#8217;s ability to continue as a going concern. These condensed consolidated financial statements
do not include any adjustments that might result from this uncertainty. There can be no assurance that such additional capital, whether
in the form of debt or equity financing, will be sufficient or available and, if available, that such capital will be offered on terms
and conditions acceptable to the Company. The Company&#8217;s primary focus is producing and selling its products. If the Company is unsuccessful
in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business
plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities. The Company believes that
its existing cash and cash equivalents as of September 30, 2023, plus expected receipts associated with product sales, will provide the
Company with liquidity to fund its planned operating needs into the first quarter of 2024.</p><span></span>

which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional
adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis
of specific identification of obsolete inventory items and quantification of slow moving inventory items. The Company determined that
it had excess and obsolete inventory, primarily related to its mmWave products, and recorded write-downs of inventory of approximately
$793,000 and $420,000 during the nine months ended September 30, 2023 and 2022, respectively. If the Company&#8217;s recognition of excess

ASC Topic 606, <i>Revenue from Contracts with Customers</i>, and its amendments (ASC 606). As described below, the analysis of contracts
under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent
with the Company&#8217;s historical practice of recognizing product revenue when title and risk of loss pass to the customer.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company generates revenue primarily from sales
of integrated circuits and antenna module products, performance of engineering services and licensing of its intellectual property. Revenues
are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to
receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract,
or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction
price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or
as a performance obligation is satisfied.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Product revenue</i></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Revenue is recognized when performance obligations
under the terms of a contract with a customer are satisfied. The majority of the Company&#8217;s contracts have a single performance obligation
to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally
at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for
transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly
to customers and through distributors generally under agreements with payment terms typically 60 days or less.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company may record an estimated allowance,
at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Royalty and other</i></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company&#8217;s licensing contracts typically
provide for royalties based on the licensee&#8217;s use of the Company&#8217;s memory technology in its currently shipping commercial
products. The Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments
are received in the subsequent quarter. The Company also generates revenue from licensing its technology. The Company recognizes license
fees as revenue at the point of time when the control of the license has been transferred and the Company has no continuing performance
obligations to the customer.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt">&#160;</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Engineering services revenue </i></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">Engineering and development contracts with customers
generally contain a single performance obligation that is delivered over time. Revenue is recognized using an output method that is consistent
with the satisfaction of the performance obligation as a measure of progress.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Deferred cost of net revenue</i></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">As of December 31, 2022, the Company had $1.1
million of product shipments for which the revenue recognition criteria under ASC 606 had not been met. Accordingly, the Company deferred
the cost of net revenue of $600,000 associated with these shipments, and the amount deferred was presented as deferred cost of net revenue
in the condensed consolidated balance sheets. During the three months ended March 31, 2023, the Company recognized the associated revenue
and cost of net revenue.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"><i>Contract liabilities &#8211; deferred revenue
</i></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company&#8217;s contract liabilities consist
of advance customer payments and deferred revenue. The Company classifies advance customer payments and deferred revenue as current or
non-current based on the timing of when the Company expects to recognize revenue. As of September 30, 2023 and December 31, 2022, contract
liabilities were in a current position and included in deferred revenue.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">During the nine months ended September 30, 2023,
the Company recognized approximately $157,000 of revenue that had been included in deferred revenue as of December 31, 2022.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">See Note 5 for disaggregation of revenue by geography.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The Company does not have significant financing
components, as payments from customers are typically due within 60 days of invoicing, and the Company has elected the practical expedient
to not value financing components that are less than one year. Shipping and handling costs are generally incurred by the customer, and,
therefore, are not recorded as revenue.</p><span></span>

model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the options, and future
dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes model. The assumptions used in the Black-Scholes

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months.</p></div>

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;span&gt;Peraso Inc.
(the Company), formerly known as MoSys, Inc. (MoSys), &lt;/span&gt;was incorporated in California in 1991 and reincorporated in 2000 in Delaware.
The Company is a fabless semiconductor company and derives revenue from selling its semiconductor devices and antenna modules, performance
of non-recurring engineering services and licensing of its technologies. The Company specializes in the development of millimeter wave
(mmWave), which is generally described as the frequency band from 24 Gigahertz (GHz) to 300GHz, wireless technology. In addition, the
Company also manufactures and sells high-performance memory semiconductor devices for a wide range of markets and receives royalties from
licensees of its memory technology.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;span&gt;On September
14, 2021, the Company and its subsidiaries, 2864552 Ontario Inc. (Callco) and 2864555 Ontario Inc. (Canco), entered into an Arrangement
Agreement (the Arrangement Agreement) with Peraso Technologies Inc. (Peraso Tech), a corporation existing under the laws of the province
of Ontario, to acquire all of the issued and outstanding common shares of Peraso Tech (the Peraso Shares), including those Peraso Shares
to be issued in connection with the conversion or exchange of secured convertible debentures and common share purchase warrants of Peraso
Tech, as applicable, by way of a statutory plan of arrangement (the Arrangement) under the Business Corporations Act (Ontario).&lt;/span&gt;
On December 17, 2021, following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was
completed and&lt;span&gt;, &lt;/span&gt;the Company changed its name to &#x201c;Peraso Inc.&#x201d; and began trading
on the Nasdaq Stock Market (the Nasdaq) under the symbol &#x201c;PRSO.&#x201d; &lt;span&gt;For accounting purposes,
Peraso Tech, the legal subsidiary, was treated as the accounting acquirer and the Company, the legal parent, was treated as the accounting
acquiree. The transaction was accounted for as a reverse acquisition in accordance with Financial Accounting Standards Board (FASB) Accounting
Standards Codification (ASC) 805, &lt;i&gt;Business Combinations&lt;/i&gt;&lt;/span&gt;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Liquidity and Going Concern&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company incurred net losses of approximately
$7.9 million for the nine months ended September 30, 2023 and $32.4 million for the year ended December 31, 2022 and had an accumulated
deficit of approximately $157.5 million as of September 30, 2023. These and prior year losses have resulted in significant negative cash
flows and have required the Company to raise substantial amounts of additional capital. To date, the Company has primarily financed its
operations through offerings of equity and equity-linked securities, issuance of convertible notes and loans.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company expects to continue to incur operating
losses for the foreseeable future as it secures new customers for and continues to invest in the development of its products. Further,
the Company expects its cash expenditures to continue to exceed receipts for the foreseeable future, as its revenues will not be sufficient
to offset its operating expenses.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company will need to increase revenues substantially
beyond levels that it has attained in the past in order to generate sustainable operating profit and sufficient cash flows to continue
doing business without raising additional capital from time to time.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As a result of the Company&#x2019;s expected operating
losses and cash burn for the foreseeable future, as well as recurring losses from operations, if the Company is unable to raise sufficient
capital through additional debt or equity arrangements, there will be uncertainty regarding the Company&#x2019;s ability to maintain liquidity
sufficient to operate its business effectively, which raises substantial doubt as to the Company&#x2019;s ability to continue as a going
concern within one year from the date of issuance of these condensed consolidated financial statements. The Company&#x2019;s independent registered public
accounting firm, in its report on the Company&#x2019;s consolidated financial statements for the year ended December 31, 2022, expressed
substantial doubt about the Company&#x2019;s ability to continue as a going concern. These condensed consolidated financial statements
do not include any adjustments that might result from this uncertainty. There can be no assurance that such additional capital, whether
in the form of debt or equity financing, will be sufficient or available and, if available, that such capital will be offered on terms
and conditions acceptable to the Company. The Company&#x2019;s primary focus is producing and selling its products. If the Company is unsuccessful
in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business
plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities. The Company believes that
its existing cash and cash equivalents as of September 30, 2023, plus expected receipts associated with product sales, will provide the
Company with liquidity to fund its planned operating needs into the first quarter of 2024.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The condensed consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been
eliminated in consolidation. The Company&#x2019;s fiscal year ends on December 31 of each calendar year. Certain prior year amounts have
been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results
of operations or cash flows.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company is subject to risks from, among other
things, competition associated with the industry in general, other risks associated with financing, liquidity requirements, rapidly changing
customer requirements, limited operating history and the volatility of public markets.&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;i&gt;COVID-19 and World Unrest&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The global outbreak of the coronavirus disease
2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020.&#160;&#160;This
negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted
in mandated closures and orders to &#x201c;shelter-in-place&#x201d; and created significant disruption of the financial markets. While the
U.S. national emergency expired in May 2023 and substantially all closures and &#x201c;shelter-in-place&#x201d; orders have ended, there
can be no assurance that the COVID-19 pandemic will not impact the Company&#x2019;s operational and financial performance in the future,
as the duration and spread of the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread
are uncertain, out of the Company&#x2019;s control, and cannot be predicted.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;World unrest due to wars and terrorist attacks
have led to further economic disruptions. Mounting inflationary cost pressures and recessionary fears have negatively impacted the global
economy. Since mid-2022, the U.S. Federal Reserve has addressed elevated inflation by increasing interest rates, as inflation remains
elevated. Given current market conditions, the Company may be unable to access the capital markets, and additional capital may only be
available to the Company on terms that could be significantly detrimental to the Company&#x2019;s existing stockholders and to the Company&#x2019;s
business.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&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 revenues and expenses recognized
during the reported period. Material estimates may include assumptions made in determining reserves for uncollectible receivables, inventory
write-downs, impairment of long-term assets, valuation allowance on deferred tax assets, accruals for potential liabilities and assumptions
made in valuing equity instruments. Actual results could differ from those estimates.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Cash Equivalents and Investments&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company has invested its excess cash in money
market accounts, certificates of deposit, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all
highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original
maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments
with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate
classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company&#x2019;s available-for-sale
investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income
(loss). Realized gains and losses and declines in the value judged to be other-than-temporary are included in the other income, net line
item in the condensed consolidated statements of operations. The cost of securities sold is based on the specific identification method.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Fair Value Measurements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company measures the fair value of financial
instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad
levels:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;1&#x2014;Inputs used to measure fair value are
unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&#160;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;2&#x2014;Pricing is provided by third party sources
of market information obtained through the Company&#x2019;s investment advisors, rather than models. The Company does not adjust for, or
apply, any additional assumptions or estimates to the pricing information it receives from advisors. The Company&#x2019;s Level&#160;2
securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, corporate
debt, and government agency and municipal debt securities from issuers with high-quality credit ratings. The Company&#x2019;s investment
advisors obtain pricing data from independent sources, such as Standard&#160;&amp;amp; Poor&#x2019;s, Bloomberg and Interactive Data Corporation,
and rely on comparable pricing of other securities because the Level&#160;2 securities are not actively traded and have fewer observable
transactions. The Company considers this the most reliable information available for the valuation of the securities.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;3&#x2014;Unobservable inputs that are supported
by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are
generally determined using pricing models for which the assumptions utilize management&#x2019;s estimates of market participant assumptions.
The determination of fair value for Level&#160;3 investments and other financial instruments involves the most management judgment and
subjectivity.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;The carrying amounts of financial assets and liabilities,
such as cash and cash equivalents, accounts receivable, accounts payable, and other payables, approximate their fair values because of
the short maturity of these instruments. The carrying values of lease obligations and long-term financing obligations approximate their
fair values because interest rates on these obligations are based on prevailing market interest rates. The Company measures the fair value
of its warrant liabilities using Level 3 inputs.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span&gt;&lt;b&gt;&lt;i&gt;Derivatives
and Liability-Classified Instruments &lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;span&gt;The Company
accounts for common stock warrants as either equity-classified or liability-classified instruments based on an assessment of the specific
terms of the warrants and the guidance provided by the Financial Accounting Standards Board (FASB) in ASC 480&lt;i&gt;, Distinguishing Liabilities
from Equity (ASC 480)&lt;/i&gt; and ASC 815, &lt;i&gt;Derivatives and Hedging (ASC 815)&lt;/i&gt;. The assessment considers whether the warrants are freestanding
financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and meet all of the requirements for
equity classification under ASC 815, including whether the warrants are indexed to the Company&#x2019;s own stock and whether the holders
of the warrants could potentially require net cash settlement in a circumstance outside of the Company&#x2019;s control, among other conditions
for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance
and as of each subsequent quarterly period end date while the warrants are outstanding.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Allowance for Doubtful Accounts&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company establishes an allowance for doubtful
accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer
credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers.
A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances
are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers
deemed creditworthy in the judgment of management. The allowance for doubtful accounts receivable was approximately $30,000 as of September
30, 2023 and approximately $183,000 as of December 31, 2022.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Inventories&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company values its inventories at the lower
of cost, which approximates actual cost on a first-in, first-out basis, or net realizable value. Costs of inventories primarily consisted
of material and third party assembly costs. The Company records inventory reserves for estimated obsolescence or unmarketable inventories
based upon assumptions about future demand and market conditions. Once a reserve is established, it is maintained until the product to
which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional
adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis
of specific identification of obsolete inventory items and quantification of slow moving inventory items. The Company determined that
it had excess and obsolete inventory, primarily related to its mmWave products, and recorded write-downs of inventory of approximately
$793,000 and $420,000 during the nine months ended September 30, 2023 and 2022, respectively. If the Company&#x2019;s recognition of excess
or obsolete inventory is, or if its estimates of inventory&#x2019;s potential utility become, less favorable than currently expected, additional
inventory write-downs may be required.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Intangible and Long-lived Assets&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Intangible assets are recorded at cost and amortized
on a straight-line method over their estimated useful lives of three to ten years. Amortization of developed technology and other intangibles
directly related to the Company&#x2019;s products is included in cost of net revenue, while amortization of customer relationships and
other intangibles not associated with the Company&#x2019;s products is included in selling, general and administrative expense in the condensed
consolidated statements of operations.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company regularly reviews the carrying value
and estimated lives of its long-lived assets and finite-lived intangible assets to determine whether indicators of impairment may exist
which warrant adjustments to carrying values or estimated useful lives. The determinants used for this evaluation include management&#x2019;s
estimate of the asset&#x2019;s ability to generate positive income from operations and positive cash flow in future periods as well as
the strategic significance of the assets to the Company&#x2019;s business objective. Should an impairment exist, the impairment loss would
be measured based on the excess of the carrying amount of the long-lived asset group over the asset&#x2019;s fair value.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Purchased Intangible Assets&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Intangible assets acquired in business combinations
are accounted for based on the fair value of assets purchased and are amortized over the period in which economic benefit is estimated
to be received. Intangible assets subject to amortization, including those acquired in business combinations were as follows (amounts
in thousands):&lt;/p&gt;

value of the customer relationships was determined by discounting estimated net future cash flows from the customer relationships. The
Company has revised the amortization period to conclude on December 31, 2024, as a result of the end-of-life announcement on May 1, 2023
(see Note 11). Amortization related to customer relationships of $0.2 million and $0.6 million for the three and nine months ended September

  &lt;/table&gt;



&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;To date, as of September 30, 2023, the Company
has not identified any intangible asset impairments. However, current macroeconomic conditions, which have been impacted by inflation
and other world unrest, could negatively impact our business and stock price and trigger the Company to test for impairment. The Company
will continue to evaluate for impairment indicators, as necessary, on a quarterly basis.&#160;&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company recognizes revenue in accordance with
ASC Topic 606, &lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt;, and its amendments (ASC 606). As described below, the analysis of contracts
under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent
with the Company&#x2019;s historical practice of recognizing product revenue when title and risk of loss pass to the customer.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company generates revenue primarily from sales
of integrated circuits and antenna module products, performance of engineering services and licensing of its intellectual property. Revenues
are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to
receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract,
or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction
price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or
as a performance obligation is satisfied.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Product revenue&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Revenue is recognized when performance obligations
under the terms of a contract with a customer are satisfied. The majority of the Company&#x2019;s contracts have a single performance obligation
to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally
at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for
transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly
to customers and through distributors generally under agreements with payment terms typically 60 days or less.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company may record an estimated allowance,
at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company&#x2019;s licensing contracts typically
provide for royalties based on the licensee&#x2019;s use of the Company&#x2019;s memory technology in its currently shipping commercial
products. The Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments
are received in the subsequent quarter. The Company also generates revenue from licensing its technology. The Company recognizes license
fees as revenue at the point of time when the control of the license has been transferred and the Company has no continuing performance
obligations to the customer.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Engineering services revenue &lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Engineering and development contracts with customers
generally contain a single performance obligation that is delivered over time. Revenue is recognized using an output method that is consistent
with the satisfaction of the performance obligation as a measure of progress.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Deferred cost of net revenue&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As of December 31, 2022, the Company had $1.1
million of product shipments for which the revenue recognition criteria under ASC 606 had not been met. Accordingly, the Company deferred
the cost of net revenue of $600,000 associated with these shipments, and the amount deferred was presented as deferred cost of net revenue
in the condensed consolidated balance sheets. During the three months ended March 31, 2023, the Company recognized the associated revenue
and cost of net revenue.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company&#x2019;s contract liabilities consist
of advance customer payments and deferred revenue. The Company classifies advance customer payments and deferred revenue as current or
non-current based on the timing of when the Company expects to recognize revenue. As of September 30, 2023 and December 31, 2022, contract
liabilities were in a current position and included in deferred revenue.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;During the nine months ended September 30, 2023,
the Company recognized approximately $157,000 of revenue that had been included in deferred revenue as of December 31, 2022.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company does not have significant financing
components, as payments from customers are typically due within 60 days of invoicing, and the Company has elected the practical expedient
to not value financing components that are less than one year. Shipping and handling costs are generally incurred by the customer, and,
therefore, are not recorded as revenue.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Cost of net revenue consists primarily of direct
and indirect costs of product sales, including amortization of intangible assets and depreciation of production-related fixed assets.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Stock-Based Compensation&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company periodically issues stock options
and restricted stock units to employees and non-employees. The Company accounts for such awards based on ASC 505 and ASC 718, whereby
the value of the award is measured on the date of award and recognized as compensation expense on a straight-line basis over the vesting
period. The fair value of the Company&#x2019;s stock options is estimated using the Black-Scholes-Merton Option Pricing (Black Scholes)
model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the options, and future
dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes model. The assumptions used in the Black-Scholes
model could materially affect compensation expense recorded in future periods.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Foreign Currency Transactions &lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The functional currency of the Company is the
U.S dollar. All foreign currency transactions are initially measured and recorded in an entity&#x2019;s functional currency using the exchange
rate on the date of the transaction. All monetary assets and liabilities are remeasured at the end of each reporting period using the
exchange rate at that date. All non-monetary assets and related expense, depreciation or amortization are not subsequently remeasured
and are measured using the historical exchange rate. An average exchange rate may be used to recognize income and expense items earned
or incurred evenly over a period. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized
in the statement of operations, except for the gains and losses arising from the conversion of the carrying amount of the foreign currency
denominated convertible preferred shares into the functional currency that are presented as adjustment to the net loss to arrive at net
loss attributable to common stockholders.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;Per-Share Amounts&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Basic net loss per share is computed by dividing
net loss for the period by the weighted-average number of exchangeable shares and shares of common stock outstanding during the period.
In addition, the Company includes the number of shares of common stock issuable under pre-funded warrants as outstanding. Diluted net
loss per share gives effect to all potentially dilutive exchangeable and common shares outstanding during the period. Potentially dilutive
common shares consist of incremental exchangeable shares and shares of common stock issuable upon the achievement of escrow terms, exercise
of stock options, vesting of stock awards and exercise of warrants. &#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The following table sets forth securities outstanding
that were excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive (in thousands):&lt;/p&gt;

$7.9 million for the nine months ended September 30, 2023 and $32.4 million for the year ended December 31, 2022 and had an accumulated
deficit of approximately $157.5 million as of September 30, 2023. These and prior year losses have resulted in significant negative cash
flows and have required the Company to raise substantial amounts of additional capital. To date, the Company has primarily financed its
operations through offerings of equity and equity-linked securities, issuance of convertible notes and loans.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company expects to continue to incur operating
losses for the foreseeable future as it secures new customers for and continues to invest in the development of its products. Further,
the Company expects its cash expenditures to continue to exceed receipts for the foreseeable future, as its revenues will not be sufficient
to offset its operating expenses.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company will need to increase revenues substantially
beyond levels that it has attained in the past in order to generate sustainable operating profit and sufficient cash flows to continue
doing business without raising additional capital from time to time.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As a result of the Company&#x2019;s expected operating
losses and cash burn for the foreseeable future, as well as recurring losses from operations, if the Company is unable to raise sufficient
capital through additional debt or equity arrangements, there will be uncertainty regarding the Company&#x2019;s ability to maintain liquidity
sufficient to operate its business effectively, which raises substantial doubt as to the Company&#x2019;s ability to continue as a going
concern within one year from the date of issuance of these condensed consolidated financial statements. The Company&#x2019;s independent registered public
accounting firm, in its report on the Company&#x2019;s consolidated financial statements for the year ended December 31, 2022, expressed
substantial doubt about the Company&#x2019;s ability to continue as a going concern. These condensed consolidated financial statements
do not include any adjustments that might result from this uncertainty. There can be no assurance that such additional capital, whether
in the form of debt or equity financing, will be sufficient or available and, if available, that such capital will be offered on terms
and conditions acceptable to the Company. The Company&#x2019;s primary focus is producing and selling its products. If the Company is unsuccessful
in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business
plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities. The Company believes that
its existing cash and cash equivalents as of September 30, 2023, plus expected receipts associated with product sales, will provide the
Company with liquidity to fund its planned operating needs into the first quarter of 2024.&lt;/p&gt;</prso:LiquidityAndGoingConcernPolicyTextBlock>

2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020.&#160;&#160;This
negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted
in mandated closures and orders to &#x201c;shelter-in-place&#x201d; and created significant disruption of the financial markets. While the
U.S. national emergency expired in May 2023 and substantially all closures and &#x201c;shelter-in-place&#x201d; orders have ended, there
can be no assurance that the COVID-19 pandemic will not impact the Company&#x2019;s operational and financial performance in the future,
as the duration and spread of the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread
are uncertain, out of the Company&#x2019;s control, and cannot be predicted.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;World unrest due to wars and terrorist attacks
have led to further economic disruptions. Mounting inflationary cost pressures and recessionary fears have negatively impacted the global
economy. Since mid-2022, the U.S. Federal Reserve has addressed elevated inflation by increasing interest rates, as inflation remains

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 revenues and expenses recognized
during the reported period. Material estimates may include assumptions made in determining reserves for uncollectible receivables, inventory
write-downs, impairment of long-term assets, valuation allowance on deferred tax assets, accruals for potential liabilities and assumptions

market accounts, certificates of deposit, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all
highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original
maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments
with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate
classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company&#x2019;s available-for-sale
investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income
(loss). Realized gains and losses and declines in the value judged to be other-than-temporary are included in the other income, net line

instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad
levels:&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;1&#x2014;Inputs used to measure fair value are
unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;2&#x2014;Pricing is provided by third party sources
of market information obtained through the Company&#x2019;s investment advisors, rather than models. The Company does not adjust for, or
apply, any additional assumptions or estimates to the pricing information it receives from advisors. The Company&#x2019;s Level&#160;2
securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, corporate
debt, and government agency and municipal debt securities from issuers with high-quality credit ratings. The Company&#x2019;s investment
advisors obtain pricing data from independent sources, such as Standard&#160;&amp;amp; Poor&#x2019;s, Bloomberg and Interactive Data Corporation,
and rely on comparable pricing of other securities because the Level&#160;2 securities are not actively traded and have fewer observable
transactions. The Company considers this the most reliable information available for the valuation of the securities.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;Level&#160;3&#x2014;Unobservable inputs that are supported
by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are
generally determined using pricing models for which the assumptions utilize management&#x2019;s estimates of market participant assumptions.
The determination of fair value for Level&#160;3 investments and other financial instruments involves the most management judgment and
subjectivity.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in"&gt;The carrying amounts of financial assets and liabilities,
such as cash and cash equivalents, accounts receivable, accounts payable, and other payables, approximate their fair values because of
the short maturity of these instruments. The carrying values of lease obligations and long-term financing obligations approximate their
fair values because interest rates on these obligations are based on prevailing market interest rates. The Company measures the fair value
of its warrant liabilities using Level 3 inputs.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;</us-gaap:FairValueMeasurementPolicyPolicyTextBlock>

accounts for common stock warrants as either equity-classified or liability-classified instruments based on an assessment of the specific
terms of the warrants and the guidance provided by the Financial Accounting Standards Board (FASB) in ASC 480&lt;i&gt;, Distinguishing Liabilities
from Equity (ASC 480)&lt;/i&gt; and ASC 815, &lt;i&gt;Derivatives and Hedging (ASC 815)&lt;/i&gt;. The assessment considers whether the warrants are freestanding
financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and meet all of the requirements for
equity classification under ASC 815, including whether the warrants are indexed to the Company&#x2019;s own stock and whether the holders
of the warrants could potentially require net cash settlement in a circumstance outside of the Company&#x2019;s control, among other conditions
for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance
and as of each subsequent quarterly period end date while the warrants are outstanding.&lt;/span&gt;&lt;/p&gt;</us-gaap:DerivativesPolicyTextBlock>

accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer
credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers.
A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances
are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers
deemed creditworthy in the judgment of management. The allowance for doubtful accounts receivable was approximately $30,000 as of September
30, 2023 and approximately $183,000 as of December 31, 2022.&lt;/p&gt;</us-gaap:TradeAndOtherAccountsReceivablePolicy>

of cost, which approximates actual cost on a first-in, first-out basis, or net realizable value. Costs of inventories primarily consisted
of material and third party assembly costs. The Company records inventory reserves for estimated obsolescence or unmarketable inventories
based upon assumptions about future demand and market conditions. Once a reserve is established, it is maintained until the product to
which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional
adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis
of specific identification of obsolete inventory items and quantification of slow moving inventory items. The Company determined that
it had excess and obsolete inventory, primarily related to its mmWave products, and recorded write-downs of inventory of approximately
$793,000 and $420,000 during the nine months ended September 30, 2023 and 2022, respectively. If the Company&#x2019;s recognition of excess
or obsolete inventory is, or if its estimates of inventory&#x2019;s potential utility become, less favorable than currently expected, additional
inventory write-downs may be required.&lt;/p&gt;</us-gaap:InventoryPolicyTextBlock>

estimate of the asset&#x2019;s ability to generate positive income from operations and positive cash flow in future periods as well as
the strategic significance of the assets to the Company&#x2019;s business objective. Should an impairment exist, the impairment loss would

ASC Topic 606, &lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt;, and its amendments (ASC 606). As described below, the analysis of contracts
under ASC 606 supports the recognition of revenue at a point in time, resulting in revenue recognition timing that is materially consistent
with the Company&#x2019;s historical practice of recognizing product revenue when title and risk of loss pass to the customer.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company generates revenue primarily from sales
of integrated circuits and antenna module products, performance of engineering services and licensing of its intellectual property. Revenues
are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to
receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract,
or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction
price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or
as a performance obligation is satisfied.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Product revenue&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Revenue is recognized when performance obligations
under the terms of a contract with a customer are satisfied. The majority of the Company&#x2019;s contracts have a single performance obligation
to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally
at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for
transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly
to customers and through distributors generally under agreements with payment terms typically 60 days or less.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company may record an estimated allowance,
at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Royalty and other&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company&#x2019;s licensing contracts typically
provide for royalties based on the licensee&#x2019;s use of the Company&#x2019;s memory technology in its currently shipping commercial
products. The Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments
are received in the subsequent quarter. The Company also generates revenue from licensing its technology. The Company recognizes license
fees as revenue at the point of time when the control of the license has been transferred and the Company has no continuing performance
obligations to the customer.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Engineering services revenue &lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Engineering and development contracts with customers
generally contain a single performance obligation that is delivered over time. Revenue is recognized using an output method that is consistent
with the satisfaction of the performance obligation as a measure of progress.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Deferred cost of net revenue&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As of December 31, 2022, the Company had $1.1
million of product shipments for which the revenue recognition criteria under ASC 606 had not been met. Accordingly, the Company deferred
the cost of net revenue of $600,000 associated with these shipments, and the amount deferred was presented as deferred cost of net revenue
in the condensed consolidated balance sheets. During the three months ended March 31, 2023, the Company recognized the associated revenue
and cost of net revenue.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;i&gt;Contract liabilities &#x2013; deferred revenue
&lt;/i&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company&#x2019;s contract liabilities consist
of advance customer payments and deferred revenue. The Company classifies advance customer payments and deferred revenue as current or
non-current based on the timing of when the Company expects to recognize revenue. As of September 30, 2023 and December 31, 2022, contract
liabilities were in a current position and included in deferred revenue.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;During the nine months ended September 30, 2023,
the Company recognized approximately $157,000 of revenue that had been included in deferred revenue as of December 31, 2022.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;See Note 5 for disaggregation of revenue by geography.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company does not have significant financing
components, as payments from customers are typically due within 60 days of invoicing, and the Company has elected the practical expedient
to not value financing components that are less than one year. Shipping and handling costs are generally incurred by the customer, and,
therefore, are not recorded as revenue.&lt;/p&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

period. The fair value of the Company&#x2019;s stock options is estimated using the Black-Scholes-Merton Option Pricing (Black Scholes)
model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the options, and future
dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes model. The assumptions used in the Black-Scholes

U.S dollar. All foreign currency transactions are initially measured and recorded in an entity&#x2019;s functional currency using the exchange
rate on the date of the transaction. All monetary assets and liabilities are remeasured at the end of each reporting period using the
exchange rate at that date. All non-monetary assets and related expense, depreciation or amortization are not subsequently remeasured
and are measured using the historical exchange rate. An average exchange rate may be used to recognize income and expense items earned
or incurred evenly over a period. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized
in the statement of operations, except for the gains and losses arising from the conversion of the carrying amount of the foreign currency
denominated convertible preferred shares into the functional currency that are presented as adjustment to the net loss to arrive at net
loss attributable to common stockholders.&lt;/p&gt;</us-gaap:ForeignCurrencyTransactionsAndTranslationsPolicyTextBlock>

net loss for the period by the weighted-average number of exchangeable shares and shares of common stock outstanding during the period.
In addition, the Company includes the number of shares of common stock issuable under pre-funded warrants as outstanding. Diluted net
loss per share gives effect to all potentially dilutive exchangeable and common shares outstanding during the period. Potentially dilutive
common shares consist of incremental exchangeable shares and shares of common stock issuable upon the achievement of escrow terms, exercise
of stock options, vesting of stock awards and exercise of warrants. &#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The following table sets forth securities outstanding

each of the three-month periods ended September 30, 2023 and 2022. Rent expense was approximately $0.6 million for each of the nine-month

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In the ordinary course of business, the Company
enters into contractual arrangements under which it may agree to indemnify the counterparties from any losses incurred relating to breach
of representations and warranties, failure to perform certain covenants, or claims and losses arising from certain events as outlined
within the particular contract, which may include, for example, losses arising from litigation or claims relating to past performance.
Such indemnification clauses may not be subject to maximum loss clauses. The Company has also entered into indemnification agreements
with its officers and directors. No material amounts were reflected in the Company&#x2019;s condensed consolidated financial statements
for the nine months ended September 30, 2023 and 2022 related to these indemnifications.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company has not estimated the maximum potential
amount of indemnification liability under these agreements due to the limited history of prior claims and the unique facts and circumstances
applicable to each particular agreement. To date, the Company has not made any payments related to these indemnification agreements.&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company warrants certain of its products to
be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim
experience and includes such costs in cost of net revenues. Warranty costs were not material for the nine months ended September 30, 2023
and 2022.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company is not a party to any legal proceeding
that the Company believes is likely to have a material adverse effect on its condensed consolidated financial position or results of operations.
From time to time the Company may be subject to legal proceedings and claims in the ordinary course of business. These claims, even if
not meritorious, could result in the expenditure of significant financial resources and diversion of management efforts.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

purchase obligations include non-cancelable purchase orders for inventory and computer-aided-design (CAD) software. At September 30, 2023,
the Company had outstanding non-cancelable purchase orders for inventory, primarily wafers and substrates, and related expenditures of
approximately $2.3 million and non-cancelable purchase orders for CAD software of $3.1 million.&lt;/p&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

accordance with ASC 280, &lt;i&gt;Segment Reporting&lt;/i&gt; (ASC 280). Management evaluates a reporting unit by first identifying its operating
segments under ASC 280. The Company then evaluates each operating segment to determine if it includes one or more components that constitute
a business. If there are components within an operating segment that meet the definition of a business, the Company evaluates those components
to determine if they must be aggregated into one or more reporting units. If applicable, when determining if it is appropriate to aggregate
different operating segments, the Company determines if the segments are economically similar and, if so, the operating segments are aggregated.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In 2010, the Company adopted the 2010 Equity Incentive
Plan and later amended it in 2014, 2017 and 2018 (the Amended 2010 Plan). The Amended 2010 Plan was terminated in August 2019 and remains
in effect as to outstanding equity awards granted prior to the date of expiration. No new awards may be made under the Amended 2010 Plan.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In August 2019, the Company&#x2019;s stockholders
approved the 2019 Stock Incentive Plan (the 2019 Plan) to replace the Amended 2010 Plan. The 2019 Plan authorizes the board of directors
or the compensation committee of the board of directors to grant a broad range of awards including stock options, stock appreciation rights,
restricted stock, performance-based awards, and restricted stock units. Under the 2019 Plan, 182,500 shares were initially reserved for
issuance. In November 2021, in connection with the approval of the Arrangement, the Company&#x2019;s stockholders approved an amendment
increasing the number of shares reserved for issuance under the 2019 Plan by 3,106,937 shares.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Under the 2019 Plan, the term of all incentive
stock options granted to a person who, at the time of grant, owns stock representing more than 10% of the voting power of all classes
of the Company&#x2019;s stock may not exceed five years. The exercise price of stock options granted under the 2019 Plan must be at least
equal to the fair market value of the shares on the date of grant. Generally, awards under the 2019 Plan will vest over a three to four-year
period, and options will have a term of 10 years from the date of grant. In addition, the 2019 Plan provides for automatic acceleration
of vesting for options granted to non-employee directors upon a change of control of the Company.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In connection with the Arrangement, the Company
assumed the Peraso Technologies Inc. 2009 Share Option Plan (the 2009 Plan) and all outstanding options granted pursuant to the terms
of the 2009 Plan. Each outstanding, unexercised and unexpired option under the 2009 Plan, whether vested or unvested, was assumed by the
Company and converted into options to purchase shares of the Company&#x2019;s common stock No further awards will be made under the 2009
Plan.&#160;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The 2009 Plan, the Amended 2010 Plan and the 2019
Plan are referred to collectively as the &#x201c;Plans.&#x201d;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company reflected compensation costs of $3.1
million and $3.4 million related to the vesting of stock options during each of the nine-month periods ended September 30, 2023 and 2022,
respectively. At September 30, 2023, the unamortized compensation cost was approximately $4.4 million related to stock options and is
expected to be recognized as expense over a weighted average period of approximately 1.2 years. The Company reflected compensation costs
of $0.8 million and $1.0 million related to the vesting of restricted stock during the nine months ended September 30, 2023 and 2022,
respectively. The unamortized compensation cost at September 30, 2023 was $1.3 million related to restricted stock units and is expected
to be recognized as expense over a weighted average period of approximately 1.3 years. There were no stock options granted or exercised
during the nine months ended September 30, 2023 and 2022.&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As discussed in Note 1, on December 17, 2021,
following the satisfaction of the closing conditions set forth in the Arrangement Agreement, the Arrangement was completed. Pursuant to
the completion of the Arrangement, each Peraso Share that was issued and outstanding immediately prior to December 17, 2021 was converted
into either newly issued shares of common stock of the Company or shares of Canco, which are exchangeable for shares of the Company&#x2019;s
common stock (Exchangeable Shares), at the election of each former Peraso Tech stockholder. Of the shares issued to the holders of Peraso
Tech Shares, pursuant to the terms of the Agreement, the Company held in escrow an aggregate of 1,312,878 Exchangeable Shares and 502,567
shares of common stock (collectively, the Escrow Shares). The Escrow Shares are escrowed pursuant to the terms of an escrow agreement
on a pro rata basis from the aggregate consideration received by the holders of Peraso Shares, subject to the offset by the Company for
any losses in accordance with the Agreement. Such Escrow Shares shall be released, subject to any offset claim, upon the satisfaction
of the earlier of: (a) any date following the first anniversary of December 17, 2021 and prior to December 17, 2024 where the volume weighted
average price of the common stock for any 20 trading days within a period of 30 consecutive trading days is at least $8.57 per share,
subject to adjustment for stock splits or other similar transactions; (b) the date of any sale of all or substantially all of the assets
or shares of the Company; or (c) the date of any bankruptcy, insolvency, restructuring, receivership, administration, wind-up, liquidation,
dissolution, or similar event involving the Company. All and any voting rights and other stockholder rights, other than with respect to
dividends and distributions, with respect to the Escrow Shares are suspended until the Escrow Shares are released from escrow.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Exchangeable Share structure is commonly used
for cross-border transactions of this nature so as to provide non-tax-exempt Canadian shareholders with the same economic rights and benefits
as holders of the Company&#x2019;s shares into which the Exchangeable Shares are exchangeable, while allowing those Canadian shareholders
to benefit from the tax-rollover available on the issuance of the Exchangeable Shares. In general terms, by choosing to acquire Exchangeable
Shares from Canco, such a former Peraso Tech shareholder was able to rely on a rollover rule in the Income Tax Act (Canada) in order to
defer any capital gain that he/she/it would have otherwise realized.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Callco was incorporated to exercise the call rights,
while Canco was incorporated to acquire the shares of Peraso Tech from Canadian shareholders that wished to receive Exchangeable Shares
as consideration, so it was a tax deferred transaction for such Canadian shareholders. The use of a separate entity, Callco, helps maximize
cross border paid-up capital, which represents the amount that can generally be distributed free of Canadian withholding tax. The call
rights also allow Callco to &#x201c;purchase&#x201d; the Exchangeable Shares rather than having them redeemed by Canco on a redemption or
retraction or in connection with a liquidity event, thus avoiding the adverse deemed dividend tax consequences to shareholders that may
arise from a redemption or retraction of Exchangeable Shares.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;Holders of Exchangeable Shares have the right
at any time (the Retraction Right) to retract or redeem any or all of the Exchangeable Shares owned by them for an amount per share equal
to the market price of a share of the Company&#x2019;s common stock plus the full amount of all declared and unpaid dividends on such Exchangeable
Share (the Exchangeable Share Purchase Price). The Exchangeable Share Purchase Price is payable only by the Company delivering or causing
to be delivered to the relevant holder one share of the Company&#x2019;s common stock for each Exchangeable Share purchased plus a cash
amount equal to the amount of any accrued and unpaid dividends on such Exchangeable Share. The Company and Callco each have an overriding
right, in the event that a holder of Exchangeable Shares exercises its Retraction Right, to redeem from such holder all, but not less
than all, of the Exchangeable Shares tendered for redemption.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Exchangeable Shares are subject to redemption
by the Company, Callco and Canco at the Exchangeable Share Purchase Price, on the &#x201c;Redemption Date,&#x201d; which date shall be no
earlier than the seventh anniversary of the date on which Exchangeable Shares are first issued, unless: (a) less than 10% of the aggregate
number of Exchangeable Shares issued remain outstanding; (b) there is a change in control of the Company (defined generally as (i) any
merger, amalgamation, arrangement, takeover bid or tender offer, material sale of shares or rights or interests that results in the holders
of outstanding voting securities of the Company directly or indirectly owning, or exercising control or direction over, voting securities
representing less than 50% of the total voting power of all of the voting securities of the surviving entity; or (ii) any sale or disposition
of all or substantially of the Company&#x2019;s assets), and (c) upon the occurrence of certain other events. The Exchangeable Share Purchase
Price is payable only by the Company delivering or causing to be delivered to the relevant holder one share of the Company&#x2019;s common
stock for each Exchangeable Share purchased plus a cash amount equal to the amount of any accrued and unpaid dividends on such Exchangeable
Share.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In the event of the liquidation, dissolution or
winding-up of Canco, holders of Exchangeable Shares have the right to receive in respect of each Exchangeable Share held by such holder,
an amount per share equal to the Exchangeable Share Purchase Price, which shall be satisfied in full by Canco by delivering to such holder
one Company Share, plus an amount equal to the Dividend Amount. The Company and Callco each have an overriding right to purchase from
all holders all but not less than all of the Exchangeable Shares upon the occurrence of such events.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In addition, the Company and Callco have the right
to purchase all outstanding Exchangeable Shares at the Exchangeable Share Purchase Price if there is a change of law that permits holders
of Exchangeable Shares to exchange their Exchangeable Shares for shares of common stock on a basis that will not require holders to recognize
any gain or loss or any actual or deemed dividend for Canadian tax purposes.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The holders of Exchangeable Shares have an &#x201c;automatic
exchange right&#x201d; in the event of any insolvency, liquidation, dissolution or winding-up or in general, related proceedings, of the
Company for an amount per share equal to the Exchangeable Share Purchase Price.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;It is expected that Callco will exercise its call
rights, as that is more beneficial to the holders of the Exchangeable Shares. Once Callco acquires the Exchangeable Shares from a holder,
it (Callco and the Company) is obligated to deliver the Company shares to the holder. Callco discharges this obligation by arranging for
the Company to issue and deliver those shares to the holders on behalf of Callco. As consideration for satisfying the delivery obligation,
Callco would issue its own shares to the Company.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;There are no cash redemption features, as all
redemption and exchange scenarios are payable in a share of the Company&#x2019;s common stock. Neither Canco, Callco, or the Company assume
any tax liabilities of a former Peraso Tech shareholder who acquired Exchangeable Shares under the plan of arrangement. The purchase price
computed upon the exercise of rights pertaining to retraction, redemption, or liquidation, or otherwise giving rise to a purchase or cancellation
of an Exchangeable Share, will, in all cases, consist of a 1:1 exchange involving the Company&#x2019;s common stock, regardless of the
market price of a share of the Company&#x2019;s common stock.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In connection with the Arrangement, on December
15, 2021, the Company filed the Certificate of Designation of Series A Special Voting Preferred Stock (the Certificate) with the Secretary
of State of the State of Delaware to designate Series A Special Voting Preferred Stock (the Special Voting Share) in accordance with the
terms of the Arrangement Agreement in order to enable the holders of Exchangeable Shares to exercise their voting rights. The Special
Voting Share was issued to a third-party administrative agent (the Agent) solely to facilitate the exercise of rights by holders of Exchangeable
Shares. The rights of the Agent, as holder of the Special Voting Share, are limited to effecting the rights of the holders of the Exchangeable
Shares; the Special Voting Share does not confer any independent rights to the Agent. Under the Certificate, when all of the Exchangeable
shares have been converted into shares of the Company&#x2019;s common stock, the Special Voting Share shall be automatically cancelled
and shall not be reissued. Each Exchangeable Share is exchangeable for one share of common stock of the Company and while outstanding,
the Special Voting Share enables holders of Exchangeable Shares to cast votes on matters for which holders of the common stock are entitled
to vote, and by virtue of the share terms relating to the Exchangeable Shares, enable the Exchangeable Shares to receive dividends that
are economically equivalent to any dividends declared with respect to the shares of common stock. As the Special Voting Share does not
participate in dividends (only the Exchangeable Shares participate in dividends) and is not entitled to participate in the residual interest
of the Company, it is not classified as an equity instrument in the Company&#x2019;s financial statements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Exchangeable Shares, which can be converted
into common stock at the option of the holder and have the same voting and dividend rights as common stock, are similar in substance to
shares of common stock. Further, Canco and Callco are non-substantive entities, which are looked through with the Exchangeable Shares
being, in substance, common stock of the Company. Therefore, the Exchangeable Shares have been included in the determination of outstanding
common stock. The Special Voting Share was issued to a third-party administrative agent (the Agent) solely to facilitate the exercise
of rights by holders of Exchangeable Shares, The rights of the Agent, as holder of the Special Voting Share, are limited to effecting
the rights of the holders of the Exchangeable Shares; the Special Voting Share does not confer any independent rights to the Agent. Under
the Certificate, when all of the Exchangeable shares have been converted into shares of the Company&#x2019;s common stock, the Special
Voting Share shall be automatically cancelled and shall not be reissued.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&#160;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;b&gt;&lt;i&gt;June 2023 Registered Direct Offering&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;On May 31, 2023, the Company entered into a securities
purchase agreement (the SPA) with an institutional investor (the Investor), pursuant to which the Company sold to the Investor, in a registered
direct offering that closed on June 2, 2023, an aggregate of 2,250,000 shares of common stock at a purchase price of $0.70 per share.
Net proceeds to the Company from the registered direct offering, after offering costs, were approximately $3.6 million. The Company also
offered and sold to the Investor pre-funded warrants to purchase up to 3,464,286 shares of common stock (the 2023 PF Warrants). Each pre-funded
warrant is exercisable for one share of common stock. The purchase price of each pre-funded warrant was $0.69, and the exercise price
of each pre-funded warrant is $0.01 per share. The 2023 PF Warrants were immediately exercisable and may be exercised at any time until
all of such pre-funded warrants are exercised in full. In June 2023, the Investor exercised 967,286 of the 2023 PF Warrants, and in September
2023, the remaining 2,497,000 of the 2023 PF &lt;span&gt;Warrants were exercised by the Investor&lt;/span&gt;. In
connection with the execution of the SPA, the Company and the Investor entered into an amendment (the Amendment) to the 2022 Purchase
Warrant. Pursuant to the terms of the Amendment, the 2022 Purchase Warrant (as defined below) was amended to reduce the exercise price
per share from $1.36 to $1.00, effective as of June 2, 2023.&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;In a concurrent private placement that closed
on June 2, 2023, the Company also sold to the Investor a warrant to purchase up to 5,714,286 shares of common stock (the 2023 Purchase
Warrant). The 2023 Purchase Warrant was immediately exercisable at an exercise price of $0.70 per share with a five-year term. As discussed
in Note 8, the 2023 Purchase Warrant is accounted for as a liability. Fair value of the warrant at the date of issuance was determined
to be $3,162,401 and was accounted for as a cost of the offering.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;span&gt;On November
28, 2022, the Company entered into a securities purchase agreement with the Investor, pursuant to which the Company sold to the Investor,
in a registered direct offering that closed on November 30, 2022, an aggregate of&#160;1,300,000&#160;shares of common stock at a negotiated
purchase price of $1.00&#160;per share. The Company also offered and sold to the investor pre-funded warrants to purchase up to&#160;1,150,000&#160;shares
of common stock. Each pre-funded warrant was exercisable for one share of common stock. The purchase price of each pre-funded warrant
was $0.99, and the exercise price of each pre-funded warrant was $0.01&#160;per share. The pre-funded warrants were exercised in full
by the Investor in April 2023. Net proceeds to the Company from the registered direct offering, after offering costs, were approximately
$2.1&#160;million.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&lt;span&gt;In a concurrent
private placement, the Company also sold to the Investor a warrant to purchase up to&#160;3,675,000&#160;shares of common stock (the 2022
Purchase Warrant). The 2022 Purchase Warrant became exercisable on May 29, 2023 at an initial exercise price of $1.36&#160;per share,
which was subsequently reduced to $1.00 per share per the Amendment, and expires on May 29, 2028. &lt;/span&gt;As discussed in Note 8, the 2022
Purchase Warrant is accounted for as a liability.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; "&gt;The 2023 Purchase Warrant
and the 2022 Purchase Warrant (collectively, the Purchase Warrants) provide for a value calculation using the Black Scholes model in the
event of certain fundamental transactions, as defined in the Purchase Warrants. The fair value calculation provides for a floor on the
volatility amount utilized in the value calculation at 100% or greater. The Company has determined that this provision introduces leverage
to the holder(s) of the Purchase Warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed
option on the Company&#x2019;s own equity shares. Therefore, pursuant to ASC 815, the Company has classified the Purchase Warrants as liabilities
in its condensed consolidated balance sheets. The classification of the Purchase Warrants, including whether the Purchase Warrants should
be recorded as liabilities or as equity, is evaluated at the end of each reporting period with changes in the fair value reported in other
income (expense) in the condensed consolidated statements of operations and comprehensive loss.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; "&gt;On June 2, 2023, the
2023 Purchase Warrant was initially recorded at a fair value at $3,162,401, and, as of September 30, 2023, the fair value of the warrant
liability was reduced to $634,828. As a result, the Company recorded a gain $2,527,572 for the nine months ended September 30, 2023 for
the change in fair value of the 2023 Purchase Warrant. The Company also recorded a gain of $1,711,527 for the nine months ended September
30, 2023 for the change in the fair value of the warrant liability for the 2022 Purchase Warrant.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in; "&gt;The fair value of the
Purchase Warrants at September 30, 2023 was determined using the Black Scholes model with the following assumptions: (i) expected term
based on the remaining contractual terms, (ii) risk-free interest rate of 4.16%, which was based on a comparable US Treasury 5-year bond,
(iii) expected volatility of 118% and (iv) an expected dividend of zero.&lt;/p&gt;

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

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;On August 5, 2022, the Company entered into a
Technology License and Patent Assignment Agreement (the Intel Agreement) with Intel Corporation (Intel), pursuant to which Intel: (i)
licensed from the Company, on an exclusive basis, certain software and technology assets related to the Company&#x2019;s Stellar packet
classification intellectual property, including its graph memory engine technology, and any roadmap variant, in the form existing as of
the date of the Agreement (the Licensed Technology); (ii) acquired from the Company certain patent applications and patents owned by the
Company; and (iii) assumed a professional services agreement, dated March 24, 2020, between Fabulous Inventions AB (Fabulous) and the
Company (the Fabulous Agreement), pursuant to which, among other things, the Company licensed from Fabulous certain technology incorporated
into the Licensed Technology.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;As consideration for the Company to enter into
the Agreement, Intel agreed to pay the Company $3,062,500 at the closing of the transaction (the Closing) and $437,500 (the Holdback)
upon the satisfaction by the Company, as mutually agreed upon by the parties in good faith, of certain release criteria set forth in the
Agreement relating to various due diligence activities of Intel regarding the Licensed Technology (the Release Criteria).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in"&gt;The Company determined that the license and asset
sale did not qualify as a sale of a business, but as a sale of a non-financial asset, with the resultant gain recorded as income from
operations in accordance with ASC 610-20, &lt;i&gt;Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets&lt;/i&gt;. During
the year ended December 31, 2022, the Company recognized a $2.6 million gain on this transaction, net of transaction costs. During the
nine months ended September 30, 2023, Intel paid the Holdback, and the Company recognized a $0.4 million gain, net of transaction costs,
which was recorded as a reduction of operating expenses in the condensed consolidated statements of operations and comprehensive loss.&lt;/p&gt;</us-gaap:AssetAcquisitionTextBlock>

Manufacturing Corporation (TSMC) is the sole foundry that manufactures the wafers used to produce the Company&#x2019;s memory IC products.
TSMC has informed the Company that TSMC is discontinuing the foundry process used to produce wafers, in turn, necessary to manufacture
the Company&#x2019;s memory ICs. As a result, in May 2023, the Company informed its customers that the Company would be initiating an end-of-life

expects shipments to extend until at least December 31, 2024.&lt;/span&gt;&lt;/p&gt;</us-gaap:ProductWarrantyDisclosureTextBlock>
