Contract analysis

I. Executive Summary Calderwood & Harkness LLP has been engaged to represent Calloway-Briggs Renewables Inc. ("CBR" or the "Company") in connection with its proposed initial public offering of approximately $600,000,000 of common stock on the New York Stock Exchange (proposed ticker: CBRI). The purpose of this memorandum is to analyze whether CBR should proceed to IPO as a traditional C-corporation or restructure int

II. Background and Current Corporate Structure A. Overview of CBR Calloway-Briggs Renewables Inc. is a Delaware corporation organized as a C-corporation for federal income tax purposes, with Employer Identification Number 83-4027615. The Company is headquartered at 4200 Ridgeline Parkway, Suite 1100, Austin, Texas 78746. CBR's registered agent in Delaware is Capitol Statutory Services, Inc., located at 1209 Orange St

III. Overview of Structural Alternatives This section provides an overview of the three structural alternatives considered for the IPO: a traditional C-corporation structure, an Up-C (umbrella partnership–C-corporation) structure, and a Down-C variant. Each structure is described in terms of its general mechanics, tax characteristics, and applicability to the CBR transaction. A. Traditional C-Corporation Structure In

IV. Detailed Analysis: C-Corp vs. Up-C for CBR This section sets forth the detailed analysis supporting our recommendation that CBR proceed as a C-corporation. We examine the structural conversion costs, tax efficiency implications, Pinnacle Vista's exit horizon and liquidity considerations, market and investor perceptions, and accounting and financial reporting factors. A. Structural Conversion Costs and Complexity

1. Current Structure Requires No Conversion As described in Section II above, CBR is already organized as a Delaware C-corporation. The entity structure — CBR at the top, with CBR Holdings LLC and CB Operating LLC below, and project-level SPVs at the bottom — is fully compatible with a C-corp IPO. No restructuring, recapitalization, or formation of new entities is required. The S-1 registration statement currently be

2. Up-C Conversion Requirements If CBR were to adopt an Up-C structure, the following steps would be required: (a) Formation or Recapitalization of an Operating Partnership. Either a new operating partnership would need to be formed, or one of the existing LLC subsidiaries (most likely CBR Holdings LLC or CB Operating LLC) would need to be recapitalized as a partnership with multiple members. This would require conve

3. Conclusion on Conversion Costs The restructuring costs (estimated at $1.5 million to $3.0 million), timeline delays (estimated at four to six weeks), and incremental complexity of an Up-C conversion are significant. These costs and delays must be weighed against the incremental tax benefits of an Up-C structure, which are analyzed in Section IV.B below. On their own terms, the conversion costs and timeline impact

1. Double Taxation Under C-Corp Structure As described in Section III.A, CBR, as a C-corporation, pays corporate income tax at the current statutory rate of 21% under Section 11 of the Code. Shareholders are subject to a second level of tax on dividends or upon the disposition of their shares. However, two important mitigating factors significantly reduce the practical impact of double taxation for CBR: First, CBR do

2. Single Layer of Tax Under Up-C (for Pre-IPO Holders) In an Up-C structure, Pinnacle Vista and the Founders would hold their economic interests at the OpCo level in the form of partnership units. Their share of OpCo's income would be subject to only a single level of tax — at the individual partner level (or, in the case of Pinnacle Vista, at the fund level and then through to the fund's limited partners). No corpo

3. Impact of Renewables-Specific Tax Attributes CBR's projects generate significant ITCs and PTCs that are currently utilized to reduce CBR's corporate income tax liability at the C-corp level. The treatment of these credits in the two structural alternatives merits specific attention. C-Corp Structure: In the current C-corp structure, ITCs generated by CBR's solar and battery storage projects and PTCs generated by C

4. Conclusion on Tax Efficiency The Up-C structure provides a meaningful but uncertain tax benefit to the pre-IPO holders, with an estimated NPV of $80 million to $120 million over 15 to 20 years (of which 85% would be paid to Pinnacle Vista under a standard TRA, and 15% would be retained by the C-corp). The C-corp's retained benefit is estimated at only $12 million to $18 million (NPV), a modest amount relative to t

1. Fund Vintage and Exit Timeline PVCP III is a 2016-vintage fund with a total fund size of $4.8 billion. Private equity funds of this vintage typically have a fund life of ten years, with potential extensions of one to two years upon approval of the fund's limited partners. This implies a target full-liquidation date of 2026 to 2028 for PVCP III, with the bulk of monetization activity expected to occur within the fi

2. Implications for Up-C If CBR were organized as an Up-C, Pinnacle Vista would hold OpCo units rather than PubCo common stock. In order to sell shares in the public market, Pinnacle Vista would first need to exchange its OpCo units for PubCo common stock pursuant to the exchange agreement. This exchange process introduces several complications for Pinnacle Vista's exit strategy: (a) Exchange Mechanics. The exchange

3. Founder Considerations Garrett Calloway and Elaine Briggs (together holding approximately 24% of pre-IPO equity, or approximately 24,000,000 shares) are expected to remain with the Company as long-term holders. Unlike Pinnacle Vista, the Founders do not have a near-term exit imperative, and an Up-C structure could theoretically benefit them more than Pinnacle Vista due to their longer expected holding period, whic

4. Conclusion on Exit Horizon Pinnacle Vista's expected exit timeline and the Founders' preference for structural simplicity strongly favor the C-corp structure. The Up-C's exchange mechanism would introduce unnecessary friction and complexity into the sponsor's exit strategy, with limited offsetting benefit given the compressed timeline. The C-corp structure facilitates straightforward public-market sales without an

1. Investor Perception of Up-C Structures Up-C structures have faced increasing scrutiny from public-market investors in recent years. While the Up-C was once viewed as an innovative tax-efficient structure, investor sentiment has shifted in several important respects: TRA Liability as a Negative Signal. The TRA liability is viewed by many institutional investors as a contingent obligation that reduces the enterprise

2. Underwriter Input In conversations with Hargrove Keating & Co. (Oliver Marchetti, Managing Director, Equity Capital Markets; Sonia Tran, Director, Power & Renewables Investment Banking), the lead underwriter has indicated the following: • The renewables-sector investor base currently has no strong preference for an Up-C structure, and a clean C-corp structure is viewed as more investor-friendly for a $600 million

3. Comparables Analysis A review of recent renewables-sector IPOs indicates that both C-corp and Up-C structures have been used, but the trend for utility-scale developers and independent power producers is toward the C-corp structure. Up-C structures remain more common in the midstream energy sector (particularly for companies transitioning from MLP structures) and in certain real estate contexts (REIT-related IPOs)

4. S-1 Disclosure Simplicity A C-corp IPO registration statement is significantly simpler than an Up-C registration statement. As noted above, an Up-C S-1 requires extensive additional disclosure regarding the Up-C structure, the exchange agreement, the TRA, and the related tax consequences. This additional disclosure adds 20 to 30 pages to the prospectus, increases the time required for SEC review, and raises the li

1. C-Corp Reporting Under the C-corp structure, CBR will file consolidated financial statements prepared in accordance with GAAP, reflecting the financial position, results of operations, and cash flows of CBR and its consolidated subsidiaries. The financial statements are audited by Ashford & Pemberton LLP (Gregory Sondheim, lead engagement partner; Irene Valdez, audit manager). HLBV methodology is currently used on

2. Up-C Reporting Complications An Up-C structure would introduce significant additional accounting complexity: (a) OpCo-Level HLBV. If OpCo were a multi-member LLC with PubCo as managing member and the pre-IPO holders as limited partners, HLBV accounting would be required at the OpCo level to allocate income and loss among the members. This would add a second layer of HLBV on top of the existing project-level HLBV a

3. Conclusion on Accounting The C-corp structure avoids significant accounting complexity, including OpCo-level HLBV, TRA liability recognition, complex EPS calculations, and non-controlling interest presentation. These accounting simplifications reduce audit costs, minimize the risk of restatements or corrections, and enhance investor understanding of CBR's financial statements. The accounting considerations further

V. Tax Receivable Agreement Analysis A. What Is a TRA? A tax receivable agreement is a contractual arrangement typically entered into in connection with an Up-C IPO or a similar restructuring transaction. Under a TRA, the publicly traded C-corporation (PubCo) agrees to pay the pre-IPO holders a specified percentage — typically 85% — of the cash tax savings realized (or, in certain formulations, deemed to be realized)

VI. Interaction with Existing Tax-Equity Structures A. Solaris West Tax-Equity Partnership Solaris West Solar LLC is a project-level special purpose vehicle that holds CBR's 450 MW solar photovoltaic project located in Pecos County, Texas. The project reached commercial operation in the third quarter of 2020. Solaris West Solar LLC is party to a tax-equity partnership with Veltara Basin Financial LLC, a subsidiary of
