<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&nbsp;1, 2019, we consummated the acquisition of substantially all of the assets of Peirce-Phelps, Inc., a Delaware corporation,
pursuant to an asset purchase agreement entered into by and among us, the selling shareholder and the other parties thereto, and issued to the selling shareholder an aggregate of 372,543 shares of Common stock of Watsco, Inc. We issued such shares
of Common stock in a private placement exempt from registration under the Securities Act of 1933, as amended, which we refer to as the Securities Act. In accordance with our obligations under a registration rights agreement entered into by and
between us and the selling shareholder on August&nbsp;1, 2019, we have agreed to register the resale of the Common stock offered by the selling shareholder hereby. Of the shares of Common stock offered hereby, 24,960 shares are subject to a
contractual restriction that generally prohibits the sale or other transfer of such shares by the selling shareholder for a period of two-years immediately following the date on which we consummated the acquisition described above. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The selling shareholder does not currently hold, and has not held within the past three years, any position or office with us or any of our
predecessors or affiliates, nor does the selling shareholder currently have, and has not had within the past three years, any other material relationship with us or any of our predecessors or affiliates. </P>

been independently verified by us. The information set forth in the following table regarding the beneficial ownership after resale of shares is based upon the assumption that the selling shareholder will sell all of the shares of Common stock owned
by it and covered by this prospectus supplement and the accompanying prospectus. </P> <P STYLE="font-size:12pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

and uncertainties described in any applicable prospectus supplement and in the other documents incorporated by reference in this prospectus. See the section entitled &#147;Where You Can Find More Information&#148; in this prospectus. The risks and
uncertainties we discuss in the documents incorporated by reference in this prospectus are those we currently believe may materially affect our company. Additional risks and uncertainties not presently known to us or that we currently believe are

</A>CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS </B></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Certain of the statements contained in this prospectus and in documents incorporated by
reference in this prospectus are &#147;forward-looking&#148; statements as defined in the Private Securities Litigation Reform Act of 1995. Generally, the words &#147;anticipate,&#148; &#147;estimate,&#148; &#147;could,&#148; &#147;should,&#148;
&#147;may,&#148; &#147;plan,&#148; &#147;seek,&#148; &#147;expect,&#148; &#147;believe,&#148; &#147;intend,&#148; &#147;target,&#148; &#147;will,&#148; &#147;project,&#148; &#147;focused,&#148; &#147;outlook,&#148; &#147;goal&#148; and similar
expressions identify forward-looking statements, which generally are not historical in nature. All statements which address future operating performance, events or developments that we expect or anticipate will occur in the future, and statements
about future operating results, are forward-looking statements, including statements regarding, among other items, (i)&nbsp;economic conditions, (ii)&nbsp;business and acquisition strategies, (iii)&nbsp;potential acquisitions and/or joint ventures
and investments in unconsolidated entities, (iv)&nbsp;financing plans and (v)&nbsp;industry, demographic and other trends affecting our financial condition or results of operations. Forward-looking statements are subject to certain risks and
uncertainties that could cause actual results to differ materially from our historical experience and our present expectations. As and when made, management believes that these forward-looking statements are reasonable. However, caution should be
taken not to place undue reliance on any such forward-looking statements since such statements speak only as of the date when made and there can be no assurance that such forward-looking statements will occur. We undertake no obligation to publicly
update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Factors exist that could cause our
actual results to differ materially from the expected results described in or underlying our forward-looking statements. Some of such factors are described under &#147;Risk Factors&#148; in our Annual Report on Form 10-K and in similar sections of
documents incorporated into this prospectus by reference. Such factors include: </P> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

Accordingly, the Board of Directors is empowered, without shareholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of
our Common stock and Class B common stock and, in certain instances, could adversely affect the market price of this stock. In the event of issuance, the preferred stock could be utilized, under certain circumstances, as a method of discouraging,
delaying or preventing a change in control of the Company or making removal of management more difficult. Please see &#147;Description of Capital Stock&#151;Material Provisions of our Amended and Restated Articles of Incorporation and Amended and

own nominees. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><U>Classified Board</U>. Our Amended and Restated Articles of Incorporation provide that our Board of Directors shall be divided into three

from obtaining control of our Board of Directors until the second annual shareholders&#146; meeting following the date the acquiring party obtains such a controlling interest. The classified board provision could discourage a potential acquiror from
making a tender offer or otherwise attempting to obtain control of the Company and could increase the likelihood that incumbent directors will retain their positions. </P>

may sell our securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and commissions from the purchasers for whom they may act as agents. Underwriters,
dealers and agents that participate in the distribution of our securities may be deemed to be underwriters under the Securities Act and any discounts or commissions they receive from us and any profit on the resale of our securities they realize may
be deemed to be underwriting discounts and commissions under the Securities Act. Any such underwriter or agent will be identified, and any such compensation received from us, will be described in the applicable prospectus supplement. Unless
otherwise set forth in the prospectus supplement relating thereto, the obligations of the underwriters or agents to purchase our securities will be subject to conditions precedent and the underwriters will be obligated to purchase all our offered
securities if any are purchased. The public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. </P>

stabilizing transactions, short covering transactions and penalty bids in accordance with securities laws. Over-allotment involves sales in excess of the offering size, which creates a short position. Stabilizing transactions permit bidders to
purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions.
Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the
securities to be higher than it would otherwise be. The underwriters may engage in these activities on any exchange or other market in which the securities may be traded. If commenced, the underwriters may discontinue these activities at any time.
