Disclaimer (cont'd) 3 Forward Looking Statements Certain statements included in this Presentation are not historical facts but are forward - looking statements, including for purp oses of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward - looking sta tements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect, " " should," "would," "plan," "project," "forecast," "predict," "potential," "seem," "seek," "future," "outlook," "target," and s imi lar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these w ord s does not mean that a statement is not forward - looking. These forward - looking statements include, but are not limited to, (1) s tatements regarding estimates and forecasts of other financial, performance and operational metrics and projections of market opportuni ty; (2) references with respect to the anticipated benefits of the Potential Business Combination and the projected future financ ia l performance of Tigo following the Potential Business Combination; (3) changes in the market for Tigo's services and technology, and expansion plans and opportunities; (4) Tigo's unit economics; (5) the sources and uses of cash of the Potential Business Combination; (6) the anticipated capitalization and enterprise value of the combined company following the consummation of th e P otential Business Combination; (7) the projected technological developments of Tigo , (8) current and future potential commercial and customer relationships; (9) the ability to operate efficiently at scale; (10) anticipated investments in capital resource s a nd research and development, and the effect of these investments; (11) the amount of redemption requests made by Roth CH's pu bli c shareholders; (12) the ability of the combined company to issue equity or equity - linked securities in the future; and (13) expec tations related to the terms and timing of the Potential Business Combination. These statements are based on various assumpti ons , whether or not identified in this Presentation, and on the current expectations of Roth CH's and Tigo's management and are not predictions of actual performance. These forward - looking statements are provided for illustrative purpos es only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Ma ny actual events and circumstances are beyond the control of Tigo . These forward - looking statements are subject to a number of risks and uncertainties, as set forth in the slide entitled "Summa ry Risk Factors" in the appendix to this Presentation and those set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward - Looking Statements" in the Registration Statement (as def ined below), Roth CH's IPO prospectus, filed with the U.S. Securities and Exchange Commission (the "SEC") on August 6, 2021, and in those documents that Roth CH has filed, or will file, with the SEC. If any of these risks materialize or our assumptions p rov e incorrect, actual results could differ materially from the results implied by these forward - looking statements. The risks and uncertainties above are not exhaustive, and there may be additional risks that neither Roth CH nor Tigo presently know or that Roth CH and Tigo currently believe are immaterial that could also cause actual results to differ from those contained in the forward - looking statements. In addition, forward looking statements reflect Roth CH's and Tigo's expectations, plans or forecasts of future events and views as of the date of this Presentation. Roth CH and Tigo anticipate that subsequent events and developments will cause Roth CH's and Tigo's assessments to change. However, while Roth CH and Tigo may elect to update these forward - looking statements at some point in the future, Roth CH and Tigo specifically disclaim any obligation to do so. These forward - looking statements should not be relied upon as representing Roth CH's and Tigo's assessments as of any date subsequent to the date of this Presentation. Accordingly, undue reliance should not be placed upon t he forward - looking statements. Trademarks Roth CH and Tigo own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of the ir respective businesses. This Presentation also contains trademarks, service marks, trade names and copyrights of third parties, which are the property of their respective owners. The use or display of third parties' trademarks, service ma rks , trade names or products in this Presentation is not intended to, and does not imply, a relationship with Roth CH or Tigo , an endorsement or sponsorship by or of Roth CH or Tigo , or a guarantee the Tigo or Roth CH will work or will continue to work with such third parties. Solely for convenience, the trademarks, service marks, t rade names and copyrights referred to in this Presentation may appear without the TM, SM,® or© symbols, but such references are not intended to indicate, in any way, that Roth CH, Tigo , or the any third - party will not assert, to the fullest extent under applicable law, their rights or the right of the applicabl e licensor to these trademarks, service marks, trade names and copyrights. Financial Information; Non - GAAP Financial Measures Some of the historical financial information contained in this presentation is unaudited and does not conform to Regulation S - X. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in any prox y statement or registration statement to be filed by Roth CH with the SEC. In addition, financial information and data containe d i n this Presentation, such as Adjusted EBITDA, Adjusted EBITDA margin, and Adjusted EBITDA less Capital Expenditures, have not be en prepared in accordance with United States generally accepted accounting principles ("GAAP"). Adjusted EBITDA is defined as ne t e arnings (loss) before interest expense, income tax expense (benefit), depreciation and amortization, as adjusted to exclude s toc k based compensation and merger transaction related expenses. These non - GAAP financial measures, and other measures that are calc ulated using such non - GAAP measures, are an addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to revenue, operating income, pro fit before tax, net income or any other performance measures derived in accordance with GAAP. For the same reasons, Tigo is unable to address the probable significance of the unavailable information, which could be material to future results. Roth CH and Tigo believe these non - GAAP measures of financial results, including on a forward - looking basis, provide useful information to manag ement and investors regarding certain financial and business trends relating to Tigo's financial condition and results of operations. Tigo's management uses these non - GAAP measures for trend analyses, for purposes of determining management incentive compensation, and for budgeting and planning purposes. Roth CH and Tigo believe that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comp ari ng Tigo's financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors. However, there are a number of limitations related to the use of these non - GAAP measures and their nearest GAAP equivalents. For example, other companies may calculate non - GAAP measures differently, or may use other measures to calculate their financial performance, and therefore Tigo's non - GAAP measures may not be directly comparable to similarly titled measures of other companies. See the Appendix for definit ions of these non - GAAP financial measures and reconciliations of these non - GAAP financial measures to the most directly comparable GAAP measures.

![](tm239295d1_425img030.jpg)

Risk Factors 30 All references to the "Company," "we," "us" or "our" refer to Tigo . The risks presented below are certain of the general risks related to the business of the Company and such list is not exha ust ive. The list below has been prepared solely for purposes of inclusion in this Presentation and not for any other purpose. You should carefully consider these risks and uncertainties, together with t he information in the Company's consolidated financial statements and related notes. Risks relating to the business of the Compa ny will be disclosed in future documents filed or furnished by the Company and/or ROCG with the SEC. The risks presented in such filings wi ll be consistent with those that would be required for a public company in their SEC filings, including with respect to the b usi ness and securities of the Company and may differ significantly from, and be more extensive than, those presented below. Risks Related to Our Business and Our Industry • We have a history of generating net losses, and if we are unable to achieve adequate revenue growth while our expenses increa se, we may not achieve or maintain profitability in the future. • Demand for our solar energy solutions may not grow or may grow at a slower rate than we anticipate and our business may suffe r. • The rapidly evolving and competitive nature of the solar industry makes it difficult to evaluate our future prospects. Our en try into adjacent markets is new and highly competitive and it is difficult to evaluate our future in these new markets as well. • Developments in alternative technologies or improvements in other forms of distributed solar energy generation may have a mat eri al adverse effect on demand for our offerings. • The market for our products is developing and may not develop as expected. • The solar industry has historically been cyclical and experienced periodic downturns. • Our integrated technological solution may not achieve broader market acceptance, which would prevent us from increasing our r eve nue and market share. • Mergers in the solar industry among our current or potential customers may adversely affect our competitive position. • Our recent and planned expansion into existing and new geographic markets or new product lines or services could subject us t o a dditional business, financial, and competitive risks. • Lithium - Ion used in our battery cells and packs can potentially catch fire or vent smoke and cause damage or injury. • If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve ou r anticipated level of growth and our business could suffer. • Any failure by management to properly manage growth could have a material adverse effect on our business, operating results, and financial condition. Risks Related to Legal, Compliance and Regulations • The reduction, elimination or expiration of government subsidies and economic incentives for on - grid solar electricity applicati ons could reduce demand for solar photo - voltaic ("PV") systems and harm our business. • Changes in current laws or regulations or the imposition of new laws or regulations, or interpretations thereof, in the solar en ergy sector or international trade, by federal or state agencies in the United States or foreign jurisdictions could impair o ur ability to compete, and could materially harm our business, financial condition and results of operations. • Our management has limited experience in operating a public company. The requirements of being a public company may strain ou r r esources and divert management's attention, and the increases in legal, accounting and compliance expenses that will result from being a public company may be greater than we anticipate. • As a private company, we have not been required to document and test our internal controls over financial reporting nor has o ur management been required to certify the effectiveness of our internal controls and our auditors have not been required to opi ne on the effectiveness of our internal control over financial reporting. Failure to maintain adequate financial, information te chn ology and management processes and controls could impair our ability to comply with the financial reporting and internal cont rol s requirements for publicly traded companies, which could lead to errors in our financial reporting and adversely affect our bu sin ess. • The installation and operation of our energy storage systems are subject to laws and regulations in various jurisdictions, an d t here is uncertainty with respect to the interpretation of certain environmental laws and regulations to our energy storage sy ste ms, especially as these regulations evolve over time. • Our significant international operations subject us to additional risks that could adversely affect our business, results of ope rations and financial condition. • Our business could be adversely affected by trade tariffs or other trade barriers. • Current or future litigation or administrative proceedings could have a material adverse effect on our business, financial co ndi tion and results of operations.

Risk Factors (cont'd) 31 Market Opportunity Risks • The market for our products is highly competitive and we expect to face increased competition as new and existing competitors in troduce or develop other smart energy products, which could negatively affect our results of operations and market share. Som e of competitors are significantly larger and have greater financial and operational capacities than us. • A drop in the retail price of electricity derived from the utility grid or from alternative energy sources may harm our busin ess , financial condition, results of operations, and prospects. • An increase in interest rates or tightening of the supply of capital in the global financial markets could make it difficult for end - users to finance the cost of a solar PV system and could reduce the demand for smart energy products and thus demand for ou r products. • Our limited operating history at current scale and our nascent industry make evaluating our business and future prospects dif fic ult. • If renewable energy technologies are not suitable for widespread adoption or sufficient demand for our hardware and software - ena bled services does not develop or takes longer to develop than we anticipate, our sales may decline and we may be unable to achieve or sustain profitability. • The failure of battery storage cost to continue to decline would have a negative impact on our business and financial conditi on. • If the estimates and assumptions we use to determine the size of our total addressable market are inaccurate, our future grow th rate may be affected and the potential growth of our business may be limited. Operating Risks • Our financial condition and results of operations and other key metrics are likely to be affected by seasonal trends and cons tru ction cycles, which could cause our results for a particular period to fall below expectations, resulting in a decline in the pr ice of our common stock. • Defects or performance problems in our products or delays, disruptions, or quality control problems in our manufacturing oper ati ons could result in loss of customers, reputational damage, and decreased revenue, and we may be the subject of numerous claims, including warranty, indemnity, and product liability claims arising from defective products. If any energy storage sy ste ms procured from original equipment manufacturers ("OEM") and provided to our customers contain manufacturing defects, our business and financial results could be adversely affected. • Future product recalls could materially adversely affect our business, financial condition and operating results. • If our estimates of useful life for our energy storage systems and related hardware and software - enabled services are inaccurate or if our OEM suppliers do not meet service and performance warranties and guarantees, our business and financial results cou ld be adversely affected. • We expect to incur research and development costs and devote resources to identifying and commercializing new products and se rvi ces, which may never result in revenue to us. • Any failure to offer high - quality technical support services may adversely affect our relationships with our customers and adver sely affect our financial results. • The loss of, or events affecting, one or more of our major customers could reduce our sales and have an adverse effect on our bu siness, financial condition and results of operations. • Our hardware and software - enabled services involve a lengthy sales and installation cycle, and if we fail to close sales on a re gular and timely basis it could adversely affect our business, financial condition and results of operations. • Our business is subject to risks associated with construction, utility interconnection, cost overruns and delays, including t hos e related to obtaining government permits and other contingencies that may arise in the course of completing installations. • We rely on distributors and installers to assist in selling our products to customers, and the failure of these providers to per form at the expected level, or at all, could have an adverse effect on our business, financial condition and results of our o per ations. • The growth of our business depends on customers renewing their monitoring services subscriptions. If customers do not continu e t o use our subscription service offerings our business and operating results will be adversely affected. • The threat of global economic, capital markets and credit disruptions pose risks to our business. • The ongoing COVID - 19 pandemic, and global measures taken in response thereto have adversely impacted, and may continue to advers ely impact, our operations and financial results. Third - Party Partner Risks • We have in some instances, and may in the future, enter into long - term supply agreements that could result in insufficient inven tory and negatively affect our results of operations. • We must maintain customer confidence in our long - term business prospects in order to grow our business. • We depend on sole - source and limited - source suppliers for key components, raw materials, and products. If we are unable to sourc e these components, raw materials, and products on a timely basis or at acceptable prices, we will not be able to deliver our products to our customers and production time and production costs could increase, which may adversely affect our business. • We depend upon a small number of outside contract manufacturers, and our business and operations could be disrupted if we enc oun ter problems with these contract manufacturers.

Risk Factors (cont'd) 32 Risks Related to Intellectual Property and Technology • Our patent applications may not result in issued patents, and our issued patents may not provide adequate protection, which m ay have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours. • Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our in tellectual property rights may be costly. • We may need to defend ourselves against claims that we infringe, have misappropriated, or otherwise violate the intellectual pro perty rights of others, which may be time - consuming and would cause us to incur substantial costs • Any unauthorized access to, disclosure, or theft of personal information we gather, store, or use could harm our reputation a nd subject us to claims or litigation. • A failure of our information technology and data security infrastructure could adversely affect our business and operations. Risks Related to Our Financial Condition and Liquidity • We are under continuous pressure to reduce the prices of our products, which has adversely affected, and may continue to adve rse ly affect, our gross margins. • If we do not forecast demand for our products accurately, we may experience product shortages, delays in product shipment, ex ces s product inventory, difficulties in planning expenses or disputes with suppliers, any of which will adversely affect our bus ine ss and financial condition. • Our focus on a limited number of specific markets increases risks associated with the modification, elimination or expiration of governmental subsidies and economic incentives for on - grid solar electricity applications.
