Subject: CPV Group - Business updates regarding the Basin Ranch Project - Towards
construction of a power plant with a capacity of approx. 1.35 GW in Texas

1.
Pursuant to Section 5B2 of the Company's Interim Reports as of March 31, 2025,1 in connection with evaluating various alternatives for the purpose of raising the capital required to construct the Basin Ranch Project2 (hereinafter - the “Project”), including by combining financing with the subsidized loan expected from TEF3 (Texas Energy Fund), taking into account, inter alia, the Project’s timetables and market conditions, the Company is pleased to update that, as of the date of this report, the Company's Board of Directors intends to proceed with financing the CPV Group's share at an estimated approx. USD 530 million (approx. NIS 1.85 billion), out of the total equity required for the Project’s construction, by way of combining capital raising by the Company, if any, as stated in an immediate report published simultaneously with this Report, with obtaining bank financing by the CPV Group, subject to completing the negotiations, in accordance with the following in this Report (rather than by way of a private offering by the CPV Group4).
 

1
A gas-fired power plant with an estimated approx. 1.35 GW in capacity in West Texas (ERCOT Market), in Ward County, Texas, with future carbon capture potential, 70% of which is held by the CPV Group and 30% - by GE Vernova and constitutes, as of the report date, an associate included in the CPV Group’s financial statements. It is clarified that the said carbon capture potential may be considered as a separate component in the future, subject to commercial and technical feasibility and to various terms and conditions that have yet to be formulated, and this component is not included in the power plant project, which is at an advanced development, pre-construction stage as stated in this report.
2
Section 5B2 to the Company's Report of the Board of Directors as of March 31, 2025, published on May 21, 2025 (Ref. No.: 2025-01-035583) (hereinafter - the "Interim Report"), which is presented by way of reference.
3
For further details regarding the process of obtaining senior debt for the Project as part of the loan from TEF, see Section 5B2 to the Interim Report (hereinafter - the "TEF Loan"). As of the date of this report, the tests have yet to be completed, as have all the documents and processes involved in obtaining a TEF loan, and all of the terms and conditions and undertakings involved (which are expected to include first-lien collateral on the Project) have yet to be formulated. As of this date, and subject to completing the said terms and conditions and tests, the Company expects the TEF Loan Agreement to be signed during the second half of 2025. It should be noted that in addition to a TEF Loan, the Project is expected to enter into agreements with lenders to receive ancillary credit facilities for the Project, including the provision of secondary lien ancillary facilities.
4
The Company and the CPV Group may reconsider options for a private placement by the CPV Group (including introducing a partner into the CPV Group), in order to - among other things - promote the CPV Group’s backlog of projects under development, taking into account the relevant timetables, circumstances (such as the level of maturity, the required capital amount) and relevant market conditions. Such a private placement, if considered, involves prolonged processes (including, inter alia, formulating the optimal capital raising structure, identifying a relevant investor, completing negotiations to formulate agreed upon transaction terms and conditions, performing due diligence and obtaining regulatory approvals and third-party consents). It should be clarified that, as of the report date, such conditions have yet to mature in order to raise capital by the CPV Group, and there is no certainty whether capital raising will be considered or executed in the future, nor regarding its timing.
 


2.
Further to the aforesaid, as of the date of the report, the CPV Group is negotiating with Bank Leumi le-Israel B.M. (hereinafter - the "Lender") to enter into an agreement to provide a loan in the amount of approx. USD 300 million for financing part of the equity required for the CPV Group's share in the construction of the Project as stated above (hereinafter - the "Financing Agreement").

3.
Additional details regarding the Project

Further to that which is stated in the Interim Report and the Company's analyst presentation dated May 21, 2025 (Ref. No.: 2025-01-035589) with respect to the Project, following are additional data regarding the Project and its market of operation as of the date of this report:
 

a)
The ERCOT market

ERCOT administers the transmission of electricity to more than 27 million consumers in the state of Texas, accounting for approx. 90% of Texas's electricity consumption. ERCOT operates as an independent system operator (ISO) and is responsible for the reliability of the electricity grid and operation of the competitive wholesale electricity market.
 
ERCOT is unique in that it operates solely within the state of Texas, under local regulation (PUCT), and is not subject to the Federal Energy Regulatory Authority (FERC). In addition, ERCOT operates largely independently of electrical transmission systems in West and East Texas.

ERCOT operates a competitive wholesale electricity market, which includes a day-ahead market and a real time market for the sale of electricity and related services. However, there is no mechanism of capacity payments for power plants, unlike the in the PJM, NYISO and ISO-NE markets.

As of the report date, ERCOT's electricity market is seeing significant, continued growth in demand, partly against the backdrop of rapid growth in the population of Texas, the expansion of industrial activity, as well as an increase in demand for electricity from energy-intensive sectors such as data centers, the oil and gas industry, and cryptocurrency mining.

In recent years, the maximum demand for electricity in the ERCOT system reached new records, and forecasts published by ERCOT indicate an average annual growth rate of approx. 13.6% in energy demand by 2031.8

It is noted that the ERCOT market is characterized by relatively high price volatility relative to the other markets in which the CPV Group operates and does not involve, as aforesaid, guaranteed capacity payments. Accordingly, once commercially operational, the Project is expected to be further exposed to the risks involved with energy prices and market conditions, and in order to reduce exposure, it is expected to enter into hedging agreements as set forth below. (For the aforementioned risk factors as stated in section 8.9, 8.21.1, 8.21.2, and 8.21.10 to Chapter A to the 2024 Periodic Report. It is further clarified that the volatility of the ERCOT markets is substantially higher, such that any unplanned downtime of the Project (such as due to extreme weather, malfunctions, etc.) may be highly material in terms of Project’s performance and its results.9


6
As of the report date, the Company indirectly holds approx. 70% of the CPV group. For details regarding the other limited partners of the CPV Group, see Section 14.2.2 to Chapter A of the Company's 2024 Periodic Report dated March 12, 2025 (Ref. No. 2025-01-016318) (hereinafter - the “Periodic Report”) and Note 23A3 to the Financial Statements attached to the Periodic Report. In addition to the preparations made by the Company and CPV Group for providing the entire equity amount needed by the CPV Group for the Project’s construction, the Company intends to negotiate with the said limited partners with respect to providing their share of the equity for the Project, in accordance with the partnership agreement between the parties. It is clarified that, as of the date of this report, the process of providing their share in the investment of the Limited Partners as stated has not yet been completed and there is no certainty as to its terms or completion.
7
It is clarified that the provisions of this Report, in connection with entering into the Binding Financing Agreement, its final terms and conditions, and actual withdrawal of the loan (including the date thereof) include forward-looking information, as defined by the Securities Law, 1968 (hereinafter - the “Securities Law”), the materialization of which is uncertain and which may materialize differently than expected, including due to factors which are not dependent on the Company, including the completion of the required tests and approvals as stated above, a change in commercial or financing terms and conditions, non-compliance with any of the conditions precedent, completion of the due diligence and approval by the financing party, and other factors, as stated below in this report.

9
As stated above, unplanned downtimes of the Project may have a material adverse effect on the Project and its results (in such a case, significant costs may be incurred under the Project's hedging agreements and other agreements and result in non-compliance with obligations towards third parties, which may result in costs and/or sanctions) and even the results of the CPV Group and the Company. For details regarding the ERCOT market, see Section 8.1.2.2 to the Periodic Report. For further details regarding the ERCOT market and the risk factors to which CPV is exposed, see Sections 8.21 and 19 to the Periodic Report.

EOX projection for natural gas and electricity prices in the Project geographical area of activity10
 
As additional background to the Project’s geographical area of activity and to provide access to additional external data available, following are forecasts of electricity and natural gas prices in the area in which the power plant will operate, which were conducted by EOX and are based on future market prices of electricity and natural gas.
 
The data in the table below reflect the forecasts of electricity and natural gas prices as obtained from EOX, with respect to the forecast of electricity prices- the information was processed by CPV Group as follows:
 
-          At peak hours, electricity is sold at the maximum volume
 
-          The remaining electricity sales were made during off-peak hours
 
The spark spread in the table below is calculated according to the following formula:
 
Spark spread (USD/MWh) = electricity price USD/MWh) – [gas Price (USD/mmBTU) X thermal conversion rate* (heat rate) (mmBTU/MWh)]
