supplement and the accompanying base prospectus are part of a registration statement that we have filed with the Securities and Exchange Commission (the &#147;SEC&#148;), utilizing a &#147;shelf&#148; registration process. Under the shelf
registration process, from time to time, we may sell any of the securities described in the accompanying base prospectus in one or more offerings. In this prospectus supplement, we provide you with specific information about this offering. This
prospectus supplement, the accompanying base prospectus and the documents incorporated by reference herein and therein include important information about us, our common stock and other information you should know before investing in our common
stock. This prospectus supplement also adds, updates and changes information contained in the accompanying base prospectus. You should read both this prospectus supplement and the accompanying base prospectus as well as the additional information
described in this prospectus supplement under the headings &#147;Where You Can Find More Information&#148; and &#147;Incorporation of Certain Documents by Reference&#148; before investing in our common stock. To the extent that any statement that we
make in this prospectus supplement is inconsistent with the statements made in the accompanying base prospectus or in any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, the statements
made in the accompanying base prospectus, or such an earlier filing, as applicable, are deemed modified or superseded by the statements made in this prospectus supplement. If any statement in one of these documents is inconsistent with a statement
in another document having a later date&#151;for example, a document incorporated by reference in the accompanying base prospectus&#151;the statement having the later date modifies or supersedes the earlier statement. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">You should rely only on the information contained or incorporated by reference in this prospectus supplement, in the accompanying base prospectus, in any
other prospectus supplement and in any free writing prospectus filed by us with the SEC. We have not, and the underwriters have not, authorized any other person to provide you with different information. If anyone provides you with different or
inconsistent information, you should not rely on it. We are not, and the underwriters are not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in
this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference herein and therein is accurate only as of each of their respective dates. Our business, financial condition, results of operations and prospects
may have changed since those dates. To the extent that any statement that we make in this prospectus supplement differs from or is inconsistent with statements made in the accompanying base prospectus or any documents incorporated by reference
therein, the statements made in this prospectus supplement will be deemed to modify or supersede those made in the accompanying base prospectus and such documents incorporated by reference therein. </P>

to, the offering of the common stock and the distribution of this prospectus outside the United States. This prospectus does not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any
securities offered by this prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This prospectus supplement contains forward-looking statements within the meaning of the federal securities laws. We make such forward-looking statements
pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and other federal securities laws. You can identify forward-looking statements by the use of the words &#147;believe,&#148; &#147;expect,&#148;
&#147;anticipate,&#148; &#147;intend,&#148; &#147;estimate,&#148; &#147;project,&#148; &#147;will,&#148; &#147;should,&#148; &#147;may,&#148; &#147;plan,&#148; &#147;assume&#148; and other expressions that predict or indicate future events and
trends and that do not relate to historical matters. You should not unduly rely on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, some of which are beyond our control. Forward-looking
statements also include the assumptions underlying or relating to any of the foregoing statements. These statements are not guarantees of future performance and are subject to risks, uncertainties, and assumptions that are difficult to predict.
Therefore, our actual results could differ materially from those expressed or implied in any forward-looking statements as a result of various factors. Such factors include, but are not limited to, the following: </P>

investment in headcount additions, Smith Micro continued to thrive in 2020 as the business remained profitable and generated $7.9&nbsp;million in cash from operations. To solidify our position as a leading white-label solution provider in the family
safety market, we purchased the operator business of Circle Media Labs Inc. (&#147;Circle&#148;) &#150; an acquisition that included multiple customer contracts and a perpetual source code license to Circle&#146;s robust parental control software.
Our development team spent the majority of 2020 integrating these features into our SafePath<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> platform, which enabled us to unveil what we believe is the most comprehensive family safety

segment, we sell primarily to large wireless carriers, cable operators, and OEMs, so there are a limited number of actual and potential customers for our current products, resulting in significant customer concentration.&nbsp;Revenues attributable
to <FONT STYLE="white-space:nowrap">T-Mobile</FONT> (and Sprint prior to its merger with <FONT STYLE="white-space:nowrap">T-Mobile)</FONT> and its affiliates accounted for 81% and 84% of the Company&#146;s total revenues for fiscal years 2020 and
2019, respectively. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">On April&nbsp;1, 2020, Sprint Corporation and <FONT STYLE="white-space:nowrap">T-Mobile</FONT> (US), Inc. <FONT
STYLE="white-space:nowrap">(&#147;T-Mobile&#148;)</FONT> completed their previously announced merger transaction, with the combined company continuing to operate as <FONT STYLE="white-space:nowrap">T-Mobile.</FONT> In connection with the <FONT

services business (&#147;Boost&#148;). A portion of our solutions sales to <FONT STYLE="white-space:nowrap">Sprint/T-Mobile</FONT> has historically included sales to Boost. The Company is working with <FONT STYLE="white-space:nowrap">T-Mobile</FONT>
and DISH on future product roadmaps and contract negotiations. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Customer Service and Technical Support </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We provide technical support and customer service through our online knowledge base, email, and live chat. OEM customers generally provide their own primary
customer support functions and rely on us for support to their technical support personnel. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Product Development </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The software industry, particularly the wireless market, is characterized by rapid and frequent changes in technology and user needs. We work closely with
industry groups and customers, both current and potential, to help us anticipate changes in technology and determine future customer needs. Software functionality depends upon the capabilities of the related hardware. Accordingly, we maintain
engineering relationships with various hardware manufacturers and we develop our software in tandem with their product development. Our engineering relationships with manufacturers, as well as with our major customers, are central to our product
development efforts. We remain focused on the development and expansion of our technology, particularly in the wireless space. Our research and development expenditures increased approximately 63% year over year, which is primarily a reflection of
additional headcount-related expenses and external contract development costs to support continued product development. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Competition </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The markets in which we operate are highly competitive and subject to rapid changes in technology. These conditions create new opportunities for Smith Micro,
as well as for our competitors, and we expect new competitors to continue to enter the market. We not only compete with other software vendors for new customer contracts, we also compete to acquire technology and qualified personnel. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We believe that the principal competitive factors affecting the mobile software market include domain expertise, product features, usability, quality, price,
customer service, speed to market and effective sales and marketing efforts. Although we believe that our products currently compete favorably with respect to these factors, there can be no assurance that we can maintain our competitive position
against current and potential competitors. We also believe that the market for our software products has been and will continue to be characterized by significant price competition. A material reduction in the price we obtain for our products would
negatively affect our profitability. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Many of our existing and potential customers have the resources to develop products that compete directly with our
products. As such, these customers may opt to discontinue the purchase of our products in the future. Our future performance is therefore substantially dependent upon the extent to which existing customers elect to purchase software from us rather
than designing and developing their own software. </P>

entered into a Membership Interest and Asset Purchase Agreement (the &#147;Purchase Agreement&#148;), with Avast plc and certain of its subsidiaries (&#147;Avast&#148;), to acquire substantially all of the assets of Avast and its subsidiaries
related to its Family Safety Mobile Software business (including application source code, license rights to shared source code, and both ownership and license rights to a patent portfolio) and certain specified assumed liabilities with respect
thereto, along with all of the outstanding membership interests of Location Labs, LLC, which comprises Avast&#146;s U.S. carrier business (the &#147;Avast Family Safety Mobile Business&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Avast Family Safety Mobile Business provides family safety mobile software, including mobile device location and parental controls features, including
screen time management and content filters. The Avast Family Safety Mobile Business also includes five mobile operator contracts, of which three are with Tier 1 U.S. operators and two are with European carriers. We also intend to enter into a
commercial partnership with Avast to provide further service to current and potential customers. Consequently, we believe the integration of the Avast Family Safety Mobile Business into Smith Micro will materially diversify and strengthen our
customer base. The acquisition also brings a robust patent portfolio covering various mobile technology innovations along with a highly skilled engineering and development talent pool specialized in digital safety applications. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We believe that the acquisition of the Avast Family Safety Mobile Business (the &#147;Avast Family Safety Mobile Acquisition&#148;) is a highly strategic,
transformational acquisition for Smith Micro that will pave the way for continued productive working relationships with major carriers, while allowing us to add critical headcount, both in the U.S. and Europe. With this acquisition, we intend to
further expand our white-label digital safety solutions, further strengthening our position as a leading family safety SaaS provider on a global basis. In particular, we believe the acquisition will enhance our core competency in digital marketing,
enabling us to accelerate our subscriber acquisition initiatives on behalf of existing carrier customers. We expect the acquisition to be immediately accretive to earnings. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Avast Family Safety Mobile Business includes certain legacy carrier contracts experiencing revenue declines. In some cases, these declines are the result
of ongoing migrations to Smith Micro&#146;s platform. In such instances, we currently expect to retain those acquired customer relationships despite the legacy nature of the acquired contracts. </P>

We expect the <FONT STYLE="white-space:nowrap">non-legacy</FONT> portion of the Avast Family Safety Mobile Business to represent between $18&nbsp;million and $19&nbsp;million of recurring revenue
on a full year basis in 2021. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Concurrently with closing, we intend to enter into a collaboration agreement with Avast that we believe will present
significant new growth opportunities for us, allowing us to jointly pursue greenfield carrier deployments incorporating <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">best-of-breed</FONT></FONT> family safety and IoT security
features. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Total consideration for the Avast Family Safety Mobile Acquisition is approximately $66.0&nbsp;million. We presently anticipate issuing
approximately $10.0&nbsp;million of Smith Micro unregistered shares of common stock as partial consideration of the purchase price, with the balance of the consideration paid with the net proceeds from this offering and cash on hand. Under the terms
of the Purchase Agreement, we will make the election whether to issue shares of common stock as partial consideration and the amount of shares to be issued, up to $51.0&nbsp;million, not less than ten business days prior to closing. Any shares of
common stock issued to Avast will be issued based on a price of approximately $6.85 per share, as set forth in the Purchase Agreement. We have also agreed to file a registration statement following the closing of the Avast Family Safety Mobile
Acquisition in order to register for resale any shares of our common stock that we elect to issue to the sellers in satisfaction of a portion of the purchase price. Of the total consideration amount, $4.95&nbsp;million will be held back for a period
of at least 12 months to secure performance of Avast&#146;s indemnification and other post-closing obligations under the Purchase Agreement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition,
if we are able to renew or otherwise enter into a contractual relationship, prior to the one year anniversary of the closing (the &#147;Anniversary Date&#148;), with a certain customer of the Avast Family Safety Mobile Business that is terminating
in the second half of 2021, then we would be obligated to pay up to an additional $14&nbsp;million of cash consideration to Avast, with such amount being reduced by $2.0&nbsp;million each month following the six-month anniversary of the closing of
the transaction. During the period beginning with the closing of the transaction and ending on the earlier of the Anniversary Date or the occurrence of the circumstances described in the preceding sentence, we shall share 75% of the gross revenues
received under the existing contract with such customer with Avast. In addition, Avast is required to deliver the Avast Family Safety Mobile Business to Smith Micro with approximately $4.5&nbsp;million in working capital at closing, and any excess
or deficit at closing will increase or decrease, respectively, the cash portion of the purchase price to be paid at closing. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The obligations of the
parties to consummate the transactions contemplated by the Purchase Agreement are subject to the satisfaction or waiver of, among other closing conditions, the accuracy of the representations and warranties in the Purchase Agreement, continued
operation of the Avast Family Safety Mobile Business by the sellers in the ordinary course up until closing (subject to our consent upon the occurrence of various events), sellers obtaining certain specified consents and approvals from third parties
to consummate the transaction, material compliance by the parties with their respective covenants and agreements under the Purchase Agreement, and delivery of other customary closing deliverables by the parties. The consummation of the Avast Family
Safety Mobile Acquisition is expected to occur in <FONT STYLE="white-space:nowrap">mid-April,</FONT> 2021. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In order to service these new customer
contracts and separate product offerings, Smith Micro will acquire approximately 160 employees from Avast and its subsidiaries. Those employees are located in (i)&nbsp;the United States and Serbia, which are existing locations for Smith Micro, and
(ii)&nbsp;the Czech Republic and Slovakia, which will become two new strategic European locations for Smith Micro. All of Smith Micro&#146;s markets provide an impressive talent population necessary to continue Smith Micro&#146;s product development
and growth. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We intend to fund a portion of the Avast Family Safety Mobile Acquisition and pay related fees, costs and expenses through the proceeds of
this offering. See &#147;Use of Proceeds.&#148; This offering is not conditioned on the closing of the Avast Family Safety Mobile Acquisition. We cannot assure you that the acquisition of the Avast Family Safety Mobile Business will be consummated

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Before deciding to invest in our common stock, you should consider carefully the following discussion of risks and uncertainties affecting us and our
common stock, as well as the risks and uncertainties incorporated by reference in this prospectus supplement and the accompanying prospectus from our Annual Report on Form <FONT STYLE="white-space:nowrap">10-K</FONT> for the fiscal year ended
December&nbsp;31, 2020, as filed with the SEC on March 8, 2021, our subsequent periodic reports and the other information contained or incorporated by reference in this prospectus supplement. If any of the events anticipated by these risks and
uncertainties occur, our business, financial condition and results of operations could be materially and adversely affected, and the value of our common stock could decline. The risks and uncertainties we discuss in this prospectus supplement and
the accompanying prospectus and in the documents incorporated by reference herein and therein are those that we currently believe may materially affect our company. Additional risks and uncertainties not presently known to us or that we currently
deem immaterial also may materially and adversely affect our business, financial condition and results of operations. </I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Related To This

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our management will have broad discretion with respect to the use of proceeds of this offering, including for any of the purposes described in the section of
this prospectus supplement entitled &#147;Use of Proceeds.&#148; You will be relying on the judgment of our management regarding the application of the proceeds of this offering, and you will not have the opportunity, as part of your investment
decision, to assess whether the proceeds are being used in ways you would agree with. The results and effectiveness of the use of proceeds are uncertain, and we could spend the proceeds in ways that you do not agree with or that do not improve our
results of operations or enhance the value of our common stock. Our failure to apply these funds effectively could harm our business and cause the price of our common stock to decline. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Although our common stock is listed on NASDAQ, we cannot assure you that an active public market will continue for our common stock. If an active public market
for our common stock does not continue, the trading price and liquidity of our common stock will be materially and adversely affected. If there is a thin trading market or &#147;float&#148; for our stock, the market price for our common stock may
fluctuate significantly more than the stock market as a whole. Without a large float, our common stock would be less liquid than the stock of companies with broader public ownership and, as a result, the trading prices of our common stock may be
more volatile. In addition, in the absence of an active public trading market, investors may be unable to liquidate their investment in us. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Furthermore,
the stock market is subject to significant price and volume fluctuations, and the price of our common stock could fluctuate widely in response to several factors, including: </P> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The stock market has experienced extreme price and volume fluctuations in recent years that have
significantly affected the quoted prices of the securities of many companies, including companies in our industry. The changes often appear to occur without regard to specific operating performance. The price of our common stock could fluctuate
based upon factors that have little or nothing to do with our company and these fluctuations could materially reduce our stock price. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>You may
experience dilution as a result of future equity offerings. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In order to raise additional capital, we may in the future offer additional shares of
our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price in this offering. We may sell shares or other securities in any other offering at a price that is less than
the price paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price at which we sell additional shares of our common stock, or securities
convertible or exchangeable into common stock, in future transactions may be higher or lower than the price paid by investors in this offering. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>We
do not anticipate paying dividends in the foreseeable future. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We do not currently pay dividends and do not anticipate paying any dividends for the
foreseeable future. Any future determination to pay dividends will be made at the discretion of our board of directors, subject to compliance with applicable laws and covenants under any future credit facility, which may restrict or limit our
ability to pay dividends. Payment of dividends will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our board of directors may deem relevant at that time. Unless and
until we declare and pay dividends, any return on your investment will only occur if our share price appreciates. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Our charter documents, Delaware
law and our commercial contracts may contain provisions that may discourage an acquisition of us by others and may prevent attempts by our stockholders to replace or remove our current management. </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Provisions in our charter documents, as well as provisions of the Delaware General Corporation Law (&#147;DGCL&#148;), could have an impact on the trading
price of our common stock by making it more difficult for a third party to acquire us at a price favorable to our shareholders. For example, our charter documents include provisions: classifying our board of directors such that only approximately <FONT
STYLE="white-space:nowrap">one-third</FONT> of the directors are elected each year; prohibiting the use of cumulative voting for the election of directors; authorizing the issuance of &#147;blank check&#148; preferred stock, the terms of which may
be established and shares of which may be issued by our board of directors without stockholder approval to defend against a takeover attempt; and establishing advance notice requirements for nominations for election to our Board of Directors or for
proposing matters that can be acted upon at stockholder meetings. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition, these provisions may frustrate or prevent any attempts by our stockholders
to replace or remove our board of directors or current management. We are subject to Section&nbsp;203 of the DGCL, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested
stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by our board of directors. This provision could have the effect of delaying or preventing a
change of control, whether or not it is desired by or beneficial to our stockholders, which could also affect the price that some investors are willing to pay for our common stock. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Finally, commercial contracts that we enter into with our vendors and customers in the course of our business operations may contain provisions with respect
to changes in control that could provide for termination rights or otherwise have a negative impact on our business or results of operations if a stockholder were to acquire a significant percentage of our outstanding stock. </P>

earnings basis that is not pursuant to GAAP and excluding transaction and integration costs) from and after the Avast acquisition, this expectation is based on assumptions, including about our and Avast&#146;s business, estimated costs and revenue
synergies, and other preliminary estimates, each of which may change materially. As a result, should the Avast Family Safety Mobile Acquisition occur, it may cause dilution to our earnings per share or the expected accretive effect of the Avast
Family Safety Mobile Acquisition may be less than anticipated, delayed or not occur at all, each of which may cause a decrease in the market price of our common stock. In addition, we could encounter additional transaction-related costs or other
factors, such as the failure to realize all of the strategic and financial benefits currently anticipated in the Avast Family Safety Mobile Acquisition, including anticipated cost and revenue synergies. All of these factors could cause dilution to
our earnings per share or decrease, delay or cause not to occur the expected accretive effect of the Avast Family Safety Mobile Acquisition and cause a decrease in the market price of our common stock. </P>

Family Safety Mobile Acquisition will be consummated on the terms described herein or at all. If the Avast Family Safety Mobile Acquisition is not consummated, we intend to use the net proceeds of this offering for general corporate purposes, which
may include future acquisitions. If the Avast Family Safety Mobile Acquisition is not consummated, this offering will cause dilution to our earnings per share, which may negatively affect the market price of our common
stock.&nbsp;&nbsp;&nbsp;&nbsp;In addition, if the Avast Family Safety Mobile Acquisition is not completed, we may experience negative reactions from the financial markets and from our customers. We also may be subject to litigation related to any
failure to complete the Avast Family Safety Mobile Acquisition. If the Acquisition is not completed, these risks may materialize and may adversely affect our business, financial results and financial condition, as well as the price of our common

of what our financial position or results of operations would have been had the Avast Family Safety Mobile Acquisition been completed on the dates indicated. The unaudited pro forma financial information has been derived from our audited historical
financial statements along with those audited abbreviated financial statements of the Avast Family Safety Mobile Business, and various adjustments and assumptions have been made regarding the combined company after giving effect to the Avast Family
Safety Mobile Acquisition. The assets and liabilities of the Avast Family Safety Mobile Business have been measured at fair value based on various preliminary estimates using assumptions that Avast&#146;s management believes are reasonable utilizing
information currently available. The process for estimating the fair value of acquired assets and assumed liabilities requires the use of judgment in determining the appropriate assumptions and estimates. These estimates and assumptions may be
revised as additional information becomes available and as additional analyses are performed. As a result, the historical financial information presented for the Avast Family Safety Mobile Acquisition may not be a reliable indicator of future
results. Differences between preliminary estimates in the pro forma financial information and the final acquisition accounting will occur and could have a material impact on the pro forma financial information and the combined company&#146;s
financial position and future results of operations. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect our financial condition or results of operations
following the Avast Family Safety Mobile Acquisition. Any potential decline in our financial condition or results of operations may cause significant variations in the trading price of our common stock following the Avast Family Safety Mobile
Acquisition. </P>

Acquisition. The purchase price for the Avast Family Safety Mobile Business is approximately $66,000,000 in a combination of cash and common stock. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The
Avast Family Safety Mobile Acquisition has been accounted for using the acquisition method of accounting. The preliminary purchase price has been allocated on a preliminary basis to the acquired assets and assumed liabilities in connection with the
acquisition based on their estimated fair values as of the closing date of the acquisition.&nbsp;The unaudited pro forma combined income statement reflects the effects of applying certain preliminary purchase accounting adjustments to the historical
consolidated results, including items expected to have a continuing impact on the consolidated results, such as amortization on acquired intangible assets. The unaudited pro forma combined income statement does not include <FONT
STYLE="white-space:nowrap">non-recurring</FONT> items such as transaction costs related to the acquisition. The final purchase price allocation is subject to the final determination of the fair values of acquired assets and assumed liabilities and,
therefore, that allocation and the resulting effect on income from operations may differ from the unaudited pro forma amounts included herein. </P>

which should be read in conjunction with this unaudited pro forma combined financial information. The pro forma adjustments described in the accompanying notes have been made based on available information and, in the opinion of management, are
reasonable. The unaudited pro forma combined financial information should not be considered indicative of actual results that would have been achieved had the acquisition occurred on the date indicated and do not purport to indicate results of
operations for any future period. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Note 2: Avast Family Safety Mobile Acquisition </B></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In order to facilitate the offering of the shares of common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the
price of the shares of common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater
than the number of shares available for purchase by the underwriters under the option to purchase additional securities. The underwriters can close out a covered short sale by exercising the option to purchase additional securities or purchasing
shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option to purchase
additional securities. The underwriters may also sell shares in excess of the option to purchase additional securities, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open
market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares of common stock in the open market after pricing that could adversely affect investors who
purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market in order to stabilize the price. These activities may raise or maintain the market
price of the shares of common stock above independent market levels or prevent or retard a decline in the market price of the shares. The underwriters may carry out these transactions on the Nasdaq Capital Market in the <FONT
STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">over-the-counter</FONT></FONT> market or otherwise. The underwriters are not required to engage in these activities and may end any of these activities at any time. </P>

representative may agree to allocate a number of shares to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters that will make internet distributions on the same basis as other
allocations. Other than the prospectus in electronic format, the information on these websites is not part of this prospectus supplement, the accompanying prospectus or the registration statement of which the accompanying prospectus forms a part,
has not been approved or endorsed by us or any underwriter in its capacity as underwriter, and should not be relied upon by investors. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Other </B></P>

registration process. Under this shelf registration process, we may offer from time to time securities having a maximum aggregate offering price of $75,000,000. Each time we offer securities, we will prepare and file with the SEC a prospectus
supplement that describes the specific amounts, prices and terms of the securities we offer. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The
prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable
prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable. You should read carefully both this prospectus and any prospectus supplement (and any free writing prospectus)
