#### SELLING STOCKHOLDER
On December 23, 2021, we completed the acquisition (the "Acquisition") of 60% of Arcadia Products, LLC, a Colorado limited liability company resulting from the conversion of Arcadia, Inc., a California corporation, following a tax reorganization ("Arcadia"). The Acquisition was completed pursuant to an equity purchase agreement by and among the Company, Arcadia, the shareholders of Arcadia, Inc. and certain other parties (the "Equity Purchase Agreement") entered into on December 16, 2021. At the closing of the Acquisition, the Company paid closing consideration of $284 million in cash (excluding $6 million in acquired cash) and 551,458 shares of its common stock, par value $0.05 per share. The shares of common stock were issued at closing to James Schladen and Victoria Schladen as trustees for the Schladen Family Trust, the selling stockholder hereunder. James Schladen is the former President of Arcadia. The selling stockholder may sell under this prospectus some, all or none of the 551,458 shares of common stock issued to it in the Acquisition.

The table below sets forth certain information regarding the selling stockholder and the shares of our common stock offered by it in this prospectus. Amounts in the "Ownership After Offering" columns represent the share ownership of the selling stockholder after completion of this offering based on the assumptions that (a) all 551,458 shares registered for resale by the registration statement of which this prospectus is a part will be sold and (b) that no other shares of our common stock are acquired by the selling stockholder or are sold prior to the completion of this offering by the selling stockholder. Percentage ownership numbers are based on 19,716,554 shares of common stock outstanding as of March 30, 2023.

The following summary is a description of the material U.S. federal income tax consequences relating to the purchase, ownership and disposition of our common stock by non-U.S. holders (as defined below) that acquire our common stock pursuant to this offering. The discussion is for general information only and does not consider all aspects of U.S. federal income taxation that may be relevant to the purchase, ownership and disposition of our common stock by a non-U.S. holder in light of its personal circumstances. In particular, this discussion does not address the U.S. federal income tax consequences of ownership of our common stock by investors that do not hold our common stock issued pursuant to this offering as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code") (generally, property held for investment), or the U.S. federal income tax consequences to beneficial owners subject to special treatment under the U.S. federal income tax laws, such as:

Non-U.S. holders subject to the special circumstances described above may be subject to tax rules that differ significantly from those summarized below.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax consequences of such partnership and the partners in such partnership generally will depend on the status of each of the partners and the activities of the partnership. Partners of partnerships considering the purchase of our common stock are encouraged to consult with their independent tax advisors.

This summary is based upon the Code, existing and proposed Treasury regulations promulgated thereunder, administrative pronouncements and judicial decisions, all in effect as of the date hereof, all of which are subject to differing interpretations or change, possibly on a retroactive basis. Such a change could affect the continuing validity of this discussion and may adversely affect a non-U.S. holder. We have not obtained, and do not intend to obtain, a ruling from the Internal Revenue Service, or the IRS, with respect to the U.S. federal income tax consequences of purchasing, owning and disposing of our common stock and there can be no assurance that the IRS will not challenge one or more of the conclusions described herein.

 **IF YOU ARE CONSIDERING THE PURCHASE OF OUR COMMON STOCK, YOU ARE ENCOURAGED TO CONSULT WITH AN INDEPENDENT TAX ADVISOR REGARDING THE APPLICATION OF U.S. FEDERAL INCOME AND ESTATE TAX LAWS, AS WELL AS OTHER U.S. FEDERAL TAX LAWS AND THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION, TO YOUR PARTICULAR SITUATION. THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL TAX CONSIDERATIONS RELATED TO THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK BY NON-U.S. HOLDERS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE.** 

#### Dividend Distributions
Any distributions with respect to the shares of our common stock, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute dividends for U.S. federal income tax purposes and will be subject to U.S. federal withholding tax at a 30% rate or such lower rate as specified by an applicable income tax treaty, provided that such dividends are not effectively connected with the non-U.S. holder's conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, are attributable to a U.S. "permanent establishment" maintained by such non-U.S. holder). Distributions in excess of our current and accumulated earnings and profits (as determined under U.S. federal income tax principles) will first constitute a return of capital that is applied against and reduces (but not below zero) the non-U.S. holder's adjusted tax basis in our common stock (determined on a share by share basis), and, to the extent such distribution exceeds the non-U.S. holder's adjusted tax basis, the excess will be treated as gain realized on the sale or other disposition of our common stock as described below under "Sale, Exchange or Other Taxable Disposition of Common Stock." Any such distributions will also be subject to the rules, regulations and obligations discussed below under the heading "FATCA."

Under the terms of an applicable U.S. income tax treaty (if any), the withholding tax might not apply, or might apply at a reduced rate. A non-U.S. holder who wishes to claim the benefit of an applicable income tax treaty is required to satisfy applicable certification and disclosure requirements (generally by providing our paying agent or a relevant withholding agent with an IRS Form W-8BEN or IRS Form W-8BEN-E). If a non-U.S. holder is eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty, such non-U.S. holder may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Dividends that are effectively connected with the conduct of a non-U.S. holder's trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S.

"permanent establishment" or "fixed base" maintained by such non-U.S. holder in the United States) are not subject to U.S. federal withholding tax if such non-U.S. holder provides our paying agent or a relevant withholding agent with an IRS Form W-8ECI, but generally will be subject to U.S. federal income tax on a net-income basis at applicable graduated individual or corporate rates, unless an applicable income tax treaty provides otherwise. A foreign corporation may be subject to an additional branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits attributable to such income.

#### Sale, Exchange or Other Taxable Disposition of Common Stock
Subject to the discussions below under "Information Reporting and Backup Withholding" and "FATCA," any gain realized by a non-U.S. holder upon the sale, exchange or other taxable disposition of shares of our common stock generally will not be subject to U.S. federal income tax unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • that gain is effectively connected with the non-U.S. holder's conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. "permanent establishment" or "fixed base" maintained by the non-U.S. holder);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • we are or have been a United States real property holding corporation (a "USRPHC") for U.S. federal income tax purposes at any time during the shorter of (i) the five-year period ending on the date of disposition and (ii) the non-U.S. holder's holding period for its shares of our common stock and, if shares of our common stock are "regularly traded on an established securities market," the non-U.S. holder held, directly or indirectly, at any time during such period, more than 5% of our issued and outstanding common stock.

Gain described in the first bullet point above will be subject to U.S. federal income tax in the same manner as that of a U.S. person, unless an applicable income tax treaty provides otherwise. If such non-U.S. holder is a foreign corporation, such gain may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits attributable to such income. A non-U.S. holder described in the second bullet point above generally will be subject to a 30% U.S. federal income tax (or a lower applicable tax treaty rate) on the gain derived from the disposition which may be offset by certain U.S.-source capital losses claimed during the taxable year.

We believe that we are not and do not anticipate becoming a USRPHC for U.S. federal income tax purposes. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. If we were a USRPHC, then so long as our common stock continued to be regularly traded on an established securities market within the meaning of the applicable Treasury regulations, only a non-U.S. holder who held more than 5% of our common stock at any time during the shorter of (i) its holding period and (ii) the five-year period preceding the date of disposition (a "greater-than-five-percent shareholder") would be subject to U.S. federal income tax on the disposition of our common stock. In such case, a greater-than-five-percent shareholder generally would be subject to U.S. federal income tax on the net gain derived from the sale in the same manner as a U.S. person, unless an applicable income tax treaty provides otherwise. Such a non-U.S. holder generally would be required to file a U.S. federal income tax return in respect of such gain. No withholding would be required upon any sale or other taxable disposition of our common stock if it is regularly traded on an established securities market. If we were a USRPHC and our common stock ceased to be regularly traded on an established securities market, a non-U.S. holder would be subject to tax on any gain recognized on the sale or other taxable disposition of our common stock, and withholding, generally at a rate of 15%, on the gross proceeds thereof, regardless of such non-U.S. holder's percentage ownership of our common stock. Non-U.S. holders are urged to consult their own tax advisors regarding the potential applicability of these rules, as well as any income tax treaty in their particular circumstances.

#### Information Reporting and Backup Withholding
We and other withholding agents generally must report annually to the IRS and to each non-U.S. holder of our common stock the amount of dividends or other distributions paid to non-U.S. holders on

------

[**TABLE OF CONTENTS**](#TOC)

shares of our common stock and the amount of tax we and other withholding agents withhold on these distributions. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides, under the provisions of an applicable income tax treaty. Information reporting also is generally required with respect to the proceeds from sales and other dispositions of our common stock to or through the U.S. office (and in certain cases, the foreign office) of a broker, unless the non-U.S. holder establishes that it is not a U.S. person for U.S. federal income tax purposes.

A non-U.S. holder will not be subject to backup withholding (the current rate of which is 24%) on reportable payments the non-U.S. holder receives on shares of our common stock if the non-U.S. holder provides proper certification (usually on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable IRS Form W-8 or successor form) of its status as a non-U.S. person.

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale or other disposition of shares of our common stock outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. However, information reporting will apply if a non-U.S. holder sells shares of our common stock outside the United States through a U.S. broker or a broker that is a controlled foreign corporation, a foreign person that derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States, or a foreign partnership that, at any time during its tax year, either is engaged in the conduct of a trade or business in the United States or has as partners one or more U.S. persons that, in the aggregate, hold more than 50% of the income or capital interests in the partnership. If a sale or other disposition is made through a U.S. office of any broker, the broker will be required to report the amount of proceeds paid to the non-U.S. holder to the IRS and to backup withhold on that amount unless the non-U.S. holder provides appropriate certification (usually on an IRS Form W-8BEN or IRS Form W-8BEN-E) to the broker certifying the non-U.S. holder's status as a non-U.S. person or other exempt status.

Any amounts withheld under the backup withholding rules will generally be allowed as a refund or a credit against a non-U.S. holder's U.S. federal income tax liability, provided the required information is properly furnished to the IRS on a timely basis.

#### FATCA
Sections 1471 through 1474 of the Code and Treasury regulations thereunder (commonly referred to as "FATCA") generally impose a 30% withholding tax on "withholdable payments," which include dividends on our common stock and gross proceeds from the disposition of our common stock paid to (i) a foreign financial institution (as defined in Section 1471 of the Code) unless it agrees to collect and disclose to the IRS information regarding direct and indirect U.S. account holders and (ii) a non-financial foreign entity unless it certifies certain information regarding substantial U.S. owners of the entity, which generally includes any U.S. person who directly or indirectly owns more than 10% of the entity. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under U.S. Treasury regulations and IRS guidance, the withholding obligations described above apply to payments of dividends on our common stock. While these withholding obligations would also apply to payments of gross proceeds from a sale or other disposition of our common stock, proposed Treasury regulations, the preamble of which states that taxpayers may rely on the proposed regulations until final regulations are issued, would eliminate withholding on payments of gross proceeds (but not on payments of dividends).

We will not pay any additional amounts to non-U.S. holders in respect of any amounts withheld, including pursuant to FATCA. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Prospective non-U.S. holders should consult their own tax advisors with respect to the potential tax consequences of FATCA.

#### PLAN OF DISTRIBUTION
The aggregate proceeds to the selling stockholder from the sale of the shares will be the purchase price less any discounts, commissions and expenses of the selling stockholder related to this offering. We expect that the selling stockholder will act independently of us in making decisions regarding the timing, manner and size of each sale. The selling stockholder reserves the right to accept and, together with its agents, to reject, any proposed purchase of shares to be made directly or through agents, for any reason, including if it deems the purchase price to be unsatisfactory at any particular time.

The shares offered by this prospectus may be sold from time to time to purchasers directly by the selling stockholder or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, commissions or agent's commissions from the selling stockholder or the purchaser(s) of the shares. These discounts, concessions or commissions may be in excess of those customary in the types of transaction involved.

The selling stockholder and any underwriters, broker-dealers or agents who participate in the sale or distribution of the shares may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act. Underwriters are subject to certain statutory liabilities, including, but not limited to, those relating to Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act. If the shares are sold through underwriters or broker-dealers, the selling stockholder will be responsible for underwriting discounts or commissions or agent's commissions. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us and the selling stockholder, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

The shares offered in this prospectus may be sold in one or more transactions at fixed prices, prevailing market prices at the time of sale, prices related to such prevailing market prices, varying prices determined at the time of sale, or negotiated prices.

These sales may be effected in one or more transactions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, including the NASDAQ;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in the over-the-counter market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in transactions otherwise than on such exchanges or services or in the over-the-counter market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in privately negotiated transactions, distributions or transfers (other than for value) by the selling stockholder to any corporation, partnership or other business entity that is a direct or indirect affiliate of the selling stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in ordinary brokerage transactions and transactions in which the broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in purchases by a broker or dealer as principal and resale by such broker or dealer for its account pursuant to this prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the writing of options (including the issuance by the selling stockholder of derivative securities), whether the options or such other derivative securities are listed on an options exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the settlement of short sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through any combination of the foregoing; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in any other manner permitted by law.

These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as an agent on both sides of the trade.

[**TABLE OF CONTENTS**](#TOC)

In connection with the sales of the shares, the selling stockholder may enter into hedging transactions. For example, the selling stockholder may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enter into transactions with a broker-dealer, an affiliate thereof or other third party in connection with which such other party may engage in sales of our common stock pursuant to this prospectus, in which case such other party may use shares of our common stock received from the selling stockholder to close out any short positions created;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • sell our common stock short itself pursuant to this prospectus and use shares of our common stock held by it to close out its short positions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enter into option or other types of transactions that require the selling stockholder to deliver our common stock to a broker-dealer or an affiliate thereof or other third party, who may then resell or transfer the common stock pursuant to this prospectus; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • loan or pledge our common stock to a broker-dealer or an affiliate thereof or other third party, who may sell the loaned shares or, in an event of default in the case of a pledge, sell the pledged shares pursuant to this prospectus.

The selling stockholder may pledge or grant a security interest in some or all of its shares. If the selling stockholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell the shares from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, and we will amend, if necessary, the name of the selling stockholder to include the pledgee, transferee or other successors in interest as selling stockholder(s) under this prospectus. The selling stockholder also may transfer and donate the shares in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The shares are listed on the NASDAQ under the symbol "BOOM".

There can be no assurance that the selling stockholder will sell any or all of the shares under this prospectus. Further, we cannot assure you that the selling stockholder will not transfer, devise or gift the shares by other means not described in this prospectus. In addition, any shares covered by this prospectus that qualify for sale under Rule 144 of the Securities Act may be sold under Rule 144 rather than under this prospectus. In addition, the selling stockholder may sell the common stock by any other legally available means. The shares may be sold in some states only through registered or licensed brokers or dealers. In addition, in some states the shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification is available and complied with.

The selling stockholder and any other person participating in the sale of the shares will be subject to the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the

------

[**TABLE OF CONTENTS**](#TOC)

timing of purchases and sales of any of the shares by the selling stockholder and any other person. These provisions may restrict certain activities of, and limit the timing of, purchases by the selling stockholder or other persons or entities. Furthermore, under Regulation M, persons engaged in a distribution of securities are prohibited from simultaneously engaging in certain activities with respect to such securities for a specified period of time prior to the commencement of such distributions, subject to special exceptions or exemptions. In addition, the anti-manipulation rules under the Exchange Act may apply to sales of the securities in the market. All of these limitations may affect the marketability of the shares and the ability of any person to engage in market-making activities with respect to the shares.

We have agreed to pay all of the expenses incidental to the registration of the shares to the public incurred by us, including the payment of federal securities law and state blue sky registration fees. We will not bear any underwriting discounts or commissions or transfer taxes relating to the sale of the shares nor any other fees or expenses incurred by the selling stockholder in connection with the registration of the shares.

Agents and underwriters may be entitled under agreements entered into with the selling stockholder to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents and underwriters may be customers of, may engage in transactions with, or perform services for, us and the selling stockholder in the ordinary course of business.

Certain entities that may act as underwriters and their respective affiliates may have, from time to time, performed, and may perform in the future, various financial advisory and investment banking services for us, the selling stockholder and affiliates, for which they received or will receive customary fees and expenses.

We will not receive any proceeds from sales of any securities by the selling stockholder.

Once sold under the registration statement of which this prospectus forms a part, the common stock will be freely tradable in the hands of persons other than our affiliates.
