to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization
of its products. 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. 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. 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-size: 10pt"><b><i>&#160;</i></b></span></p></ix:continuation></ix:continuation><div>

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.

June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, <i>Financial Instruments&#8212;Credit Losses</i>. This ASU
added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred
losses. Under the new guidance, an entity recognizes an allowance for its estimate of expected credit losses and applies to most debt
instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not
have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that
have a low risk of loss. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within
those fiscal years for smaller reporting companies. The adoption of ASU 2016-13 did not have a significant impact on the Company&#8217;s
condensed consolidated financial statement presentation or disclosures.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "><span style="font-size: 10pt">&#160;</span></p></ix:continuation></ix:continuation><div>

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="c159" decimals="-3" format="ixt:num-dot-decimal" name="us-gaap:ExcessStockSharesIssued" scale="3" unitRef="shares">1,312,878</ix:nonFraction> Exchangeable Shares and <ix:nonFraction contextRef="c159" decimals="-3" format="ixt:num-dot-decimal" name="prso:ExchangeableSharesCommonStock" scale="3" unitRef="shares">502,567</ix:nonFraction> 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 $<ix:nonFraction contextRef="c159" decimals="2" format="ixt:num-dot-decimal" name="us-gaap:SharesIssuedPricePerShare" scale="0" unitRef="usdPershares">8.57</ix:nonFraction> 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p></ix:continuation><div>

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p></ix:continuation><div>

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p></ix:continuation><div>

strategy 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><span style="font-size: 10pt">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.</span></p><div>

also acquired a memory product line marketed under the Accelerator Engine name. This memory product line comprises our Bandwidth Engine

losses of&#160;approximately $3.1 million for the three months ended March 31, 2023 and $32.4 million for the year ended December 31,
2022, and we had an accumulated deficit of&#160;approximately $152.7 million&#160;as of March 31, 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.</span></p><div>

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 memory IC 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 during 2023 that we expect to fulfill during 2024. We are requiring
customers to pay a deposit upon purchase order placement to reserve supply and provide funding for our required inventory purchases.
Under our EOL plan, we intend to complete all shipments of our memory products during 2024, and, as a result, we do not anticipate any
shipments of our memory products after December 31, 2024. However, the timing of EOL shipments will be dependent on deliveries from our
suppliers, as well as the delivery schedules requested by our customers.</span></p><div>

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. Since March 2020, from time to time, this has 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. The full extent of the COVID-19 impact on our operational and financial
performance will depend on future developments, including the duration and spread of the pandemic and related actions taken by the U.S.
and foreign government agencies to prevent disease spread, all of which are uncertain, out of our control, and cannot be predicted.</span></p><div>

of COVID-19 has also led to disruption and volatility in the global capital markets. The Russian invasion of Ukraine in February 2022
has 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, we may be unable to access the capital markets, and additional capital may only be available
to us on terms that could be significantly detrimental to our existing stockholders and to our business.</span></p><div>

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 we expect 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.</span></p><div>

customer, generally at the time of shipment of products. Revenue is measured as the amount of consideration we expect to receive in exchange
for transferring products and is generally based upon a negotiated, formula, list or fixed price. We sell our products both directly
to customers and through distributors generally under agreements with payment terms typically 60 days or less.</span></p><div>

increased for the three months ended March 31, 2023 compared with the same period of 2022 primarily due to recognition of revenue of
approximately $1.1 million for shipments during the three months ended September 30, 2022 upon payment by the customer and satisfaction
of the revenue recognition criteria. We initiated price increases on certain of our antenna module products in 2022, however, through
March 31, 2023, we had not realized any material increase in revenue as a result of those price increases. The increase in memory IC
sales was mainly due to larger shipments to one customer. In late 2022, we implemented modest price increases on our memory products,
and, during the three months ended March 31, 2023, contributed $0.1 million to the revenue increase.</span></p><div>

revenue perspective during the remainder of 2023, as compared with 2022, based on current customer forecasts. Given the planned EOL
discussed above, we do not expect revenue from these products beyond 2024.</span></p><div>

significant negative cash flows and have required us to raise substantial amounts of additional capital. To date, we have primarily financed

to increase revenues beyond the 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. 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 August 2022, we entered into an exclusive technology license and patent assignment
agreement with Intel Corporation, under which we collected $3.1 million in August 2022 and $0.4 million in January 2023. We expect
this transaction to result in a reduction of operating expenses of approximately $2.7 million on annual basis. In November 2022, we
completed a registered direct offering of common stock and warrants for net proceeds to us of approximately $2.1 million. Further,
in February 2023, we announced that we had implemented cost-reduction initiatives to reduce operating expenses by approximately $5
million on an annualized basis.</span></p><div>

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:</span></p><div>

to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization
of its products. 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. 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. 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-size: 10pt"><b><i>&#160;</i></b></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-size: 10pt"><b><i>Basis of Presentation</i></b></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">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

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 short-term and long-term 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

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

Company values its inventories at the lower of cost, which approximates actual cost on a first-in, first-out basis, or net realizable

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 recorded write-downs of inventory of approximately $361,000 and $114,000 during the three

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt"><i>&#160;</i></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt"><i>Product revenue</i></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">Revenue is recognized

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

added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred
losses. Under the new guidance, an entity recognizes an allowance for its estimate of expected credit losses and applies to most debt
instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not
have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that
have a low risk of loss. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within
those fiscal years for smaller reporting companies. The adoption of ASU 2016-13 did not have a significant impact on the Company&#8217;s

option on the Company&#8217;s own equity shares. Therefore, pursuant to ASC 815, the Company has classified the Purchase Warrant as a
liability in its condensed consolidated balance sheets. The classification of the Purchase Warrant, including whether the Purchase Warrant
should be recorded as liability 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "><span style="font-size: 10pt">The

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

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">The

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

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">The
holders of Exchangeable Shares have an &#8220;automatic exchange right&#8221; in the event of any insolvency, liquidation, dissolution

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-size: 10pt"><b><i>Warrants </i></b></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"><span style="font-size: 10pt">As of March 31,

2022 and had an accumulated deficit of approximately $152.7 million as of March 31, 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

to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization
of its products. 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. 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. 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-size: 10pt"><b><i>&#160;</i></b></span></p><span></span>

is provided by third party sources 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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"><span style="font-size: 10pt">Level&#160;3&#8212;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&#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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"><span style="font-size: 10pt">The carrying amounts of financial
assets and liabilities, such as cash and cash equivalents, accounts receivable, accounts payable, notes 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 liability using Level 3 inputs.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-size: 10pt"><b><i>&#160;</i></b></span></p><span></span>

Company values its inventories at the lower of cost, which approximates actual cost on a first-in, first-out basis, or net realizable

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 recorded write-downs of inventory of approximately $361,000 and $114,000 during the three

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.</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt"><i>&#160;</i></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt"><i>Product revenue</i></span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">&#160;</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"><span style="font-size: 10pt">Revenue is recognized

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

added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred
losses. Under the new guidance, an entity recognizes an allowance for its estimate of expected credit losses and applies to most debt
instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not
have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that
have a low risk of loss. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within
those fiscal years for smaller reporting companies. The adoption of ASU 2016-13 did not have a significant impact on the Company&#8217;s

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>

Inc. (the Company), formerly known as MoSys, Inc. (MoSys), &lt;/span&gt;&lt;span style="font-size: 10pt"&gt;was incorporated in California in 1991
and reincorporated in 2000 in Delaware. The Company is a fabless semiconductor company specializing in the development of millimeter
wave (mmWave), which is generally described as the frequency band from 24 Gigahertz (GHz) to 300GHz, wireless technology. 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. The Company derives revenue from selling its semiconductor devices and antenna modules, performance of non-recurring
engineering services and licensing of its technologies.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt; "&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; &lt;span style="font-size: 10pt"&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; (ASC 805)&lt;/span&gt;.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;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&#x2019;s consolidated financial statements and notes thereto
included in its most recent annual report on Form&#160;10-K filed with the SEC.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;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&#x2019;s financial position, results of operations and cash flows for
the interim periods presented. The operating results for the three months ended March 31, 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.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Liquidity and Going Concern&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The Company incurred
net losses of approximately $3.1 million for the three months ended March 31, 2023 and $32.4 million for the year ended December 31,
2022 and had an accumulated deficit of approximately $152.7 million as of March 31, 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 multiple offerings of common stock and issuance of convertible notes and loans to investors
and affiliates.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The Company expects
to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization
of its products. 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. 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. 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.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Basis of Presentation&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Risks and Uncertainties&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;COVID-19&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;Since March 2020, from time to time, this has 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. The full extent of the COVID-19 impact
on the Company&#x2019;s operational and financial performance will depend on future developments, including the duration and spread of
the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread, all of which are uncertain,
out of the Company&#x2019;s control, and cannot be predicted.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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, purchase price allocations, 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Cash Equivalents and Investments&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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 short-term and long-term 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.

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The carrying amounts of financial
assets and liabilities, such as cash and cash equivalents, accounts receivable, accounts payable, notes 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 liability using Level 3 inputs.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt; "&gt;&lt;b&gt;&lt;i&gt;Derivatives

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;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Allowance for Doubtful Accounts&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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 zero as of March 31, 2023 and approximately $183,000 as of December 31, 2022.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Inventories&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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 recorded write-downs of inventory of approximately $361,000 and $114,000 during the three
months ended March 31, 2023 and 2022, respectively.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Tax Credits &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-indent: 0.5in"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The

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 SG&amp;amp;A

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Purchased Intangible Assets&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="text-align: left; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;Intangible

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Product revenue&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Royalty and
other&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Engineering

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

months ended September 30, 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 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Contract liabilities

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 March 31, 2023
and December 31, 2022, contract liabilities were in a current position and included in deferred revenue.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;During the three
months ended March 31, 2023, the Company recognized approximately $88,000 of revenue that had been included in deferred revenue as of
December 31, 2022.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;See Note 5 for

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Cost of Net Revenue&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Stock-Based Compensation&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Foreign Currency Transactions

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&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"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Per-Share Amounts&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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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. 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The following table

June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, &lt;i&gt;Financial Instruments&#x2014;Credit Losses&lt;/i&gt;. This ASU
added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred
losses. Under the new guidance, an entity recognizes an allowance for its estimate of expected credit losses and applies to most debt
instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not
have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that
have a low risk of loss. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within
those fiscal years for smaller reporting companies. The adoption of ASU 2016-13 did not have a significant impact on the Company&#x2019;s
condensed consolidated financial statement presentation or disclosures.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;Management
does not believe that any other recently issued, but not yet effective, authoritative guidance, if currently adopted, would have a material

net losses of approximately $3.1 million for the three months ended March 31, 2023 and $32.4 million for the year ended December 31,
2022 and had an accumulated deficit of approximately $152.7 million as of March 31, 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 multiple offerings of common stock and issuance of convertible notes and loans to investors
and affiliates.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The Company expects
to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization
of its products. 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. 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. 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.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;</prso:LiquidityAndGoingConcernPolicyTextBlock>

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 short-term and long-term investments are carried at fair value, with the unrealized

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

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,

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 zero as of March 31, 2023 and approximately $183,000 as of December 31, 2022.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;</us-gaap:TradeAndOtherAccountsReceivablePolicy>

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 recorded write-downs of inventory of approximately $361,000 and $114,000 during the three
months ended March 31, 2023 and 2022, respectively.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;</us-gaap:InventoryPolicyTextBlock>

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Product revenue&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Royalty and
other&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Engineering

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

months ended September 30, 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 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&lt;i&gt;Contract liabilities

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 March 31, 2023
and December 31, 2022, contract liabilities were in a current position and included in deferred revenue.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;During the three
months ended March 31, 2023, the Company recognized approximately $88,000 of revenue that had been included in deferred revenue as of
December 31, 2022.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;See Note 5 for

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;&#160;&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

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

June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, &lt;i&gt;Financial Instruments&#x2014;Credit Losses&lt;/i&gt;. This ASU
added a new impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred
losses. Under the new guidance, an entity recognizes an allowance for its estimate of expected credit losses and applies to most debt
instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not
have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that
have a low risk of loss. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within
those fiscal years for smaller reporting companies. The adoption of ASU 2016-13 did not have a significant impact on the Company&#x2019;s
condensed consolidated financial statement presentation or disclosures.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;Management

warrant to purchase shares of our common stock at an exercise price of $1.00&#160;per share (the Purchase Warrant) was issued on November
30, 2022 in conjunction with a registered direct offering to an institutional investor. &lt;/span&gt;&lt;span style="font-size: 10pt"&gt;The stock
purchase agreement governing the Purchase Warrant provides for a value calculation for the Purchase Warrant using the Black Scholes model
in the event of certain fundamental transactions (as defined in the stock purchase agreement). 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 this provision introduces
leverage to the holder of the Purchase Warrant 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 Warrant as a
liability in its condensed consolidated balance sheets. The classification of the Purchase Warrant, including whether the Purchase Warrant
should be recorded as liability 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;The

5-year bond, (iii) expected volatility of 114% and (iv) an expected dividend of zero.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; "&gt;&lt;span style="font-size: 10pt"&gt;As

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 three months ended March 31, 2023 and 2022 related to these indemnifications.&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The Company has

its reporting units in 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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;Management has

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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;The 2009 Plan,

compensation costs of $1.1 million related to the vesting of stock options during each of the three-month periods ended March 31, 2023
and 2022, respectively. At March 31, 2023, the unamortized compensation cost was approximately $6.6 million related to stock options
and is expected to be recognized as expense over a weighted average period of approximately 1.6 years. The Company reflected compensation
costs of $0.2 million and $0.1 million related to the vesting of restricted stock during the three months ended March 31, 2023 and 2022,
respectively. The unamortized compensation cost at March 31, 2023 was $1.8 million related to restricted stock units and is expected
to be recognized as expense over a weighted average period of approximately 1.8 years. There were no stock options granted or exercised

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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/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;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&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;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&lt;span style="font-size: 10pt"&gt;&lt;b&gt;&lt;i&gt;Warrants &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-indent: 24.5pt"&gt;&lt;span style="font-size: 10pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;span style="font-size: 10pt"&gt;As of March 31,

necessary to manufacture the Company&#x2019;s memory ICs. As a result, effective May 1, 2023, the Company began informing its memory IC
customers that the Company would be initiating an end-of-life, or EOL, of its memory IC products. The Company has notified its customers
to provide purchase orders during 2023 that the Company expects to fulfill during 2024. However, the timing of EOL shipments will be
