      Financial
    
    
      •In April 2025, Phase 1 LLC elected to terminate $250 million of commitments under its working capital facility due to a decrease in expected requirements for credit support during construction, which reduced the outstanding commitments under the working capital facility to $250 million and is expected to reduce related commitment fees by approximately $2 million annually.
    
    
      •In May 2025, our wholly-owned subsidiary Rio Grande LNG Super Holdings, LLC, entered into an amendment to the credit agreement with the lender of its existing senior secured loan (the "Super Holdings Loan") to increase the loan amount by $50
    
    
      
    
    
      million to a total of $225 million initial principal. Incremental proceeds from the Super Holdings Loan were disbursed at closing on May 14, 2025, and net proceeds can be used to fund working capital and general corporate purposes, including development expenses for expansion trains at the Rio Grande LNG Facility and specifically pre-FID expenses for Trains 4 and 5. Borrowings under the Super Holdings Loan bear interest at 12.0%, with interest payable quarterly. Interest may be paid in-kind until March 31, 2027 and up to 50% in-kind thereafter. The Super Holdings Loan matures December 31, 2030.
    
    
      •In conjunction with the closing of the May 2025 amendment to the Super Holdings Loan, we issued warrants that are exercisable for an aggregate of approximately 2.0 million shares of our common stock to the lender of the Super Holdings Loan. The warrants are exercisable for five years after the amendment date at $9.30 per share, which represented a 30% premium to the volume weighted average price for the 30 trading-day period immediately preceding the amendment date.
    
    
      •On September 9, 2025, in conjunction with the positive FID on Train 4 at the Rio Grande LNG Facility, we and certain of our subsidiaries closed an approximately $6.7 billion project financing for Train 4, which included the closing of:
    
    
      ◦A joint venture agreement which included approximately $1.69 billion of financial commitments from Global Infrastructure Partners, a part of BlackRock ("GIP"), GIC, Mubadala Investment Company, and TotalEnergies;
    
    
      ◦A commitment by the Company to invest approximately $1.13 billion in Train 4; and
    
    
      ◦A senior secured, non-recourse bank credit facility of $3.85 billion with a seven year maturity.
    
    
      •On September 9, 2025, to fully fund the Company's approximately $1.13 billion equity commitments for Train 4, certain of our wholly-owned subsidiaries entered into a delayed draw, senior secured term loan bank facility of $734 million with a five year maturity (the "FinCo Loan") and term loans of $600 million with a maturity date of the earlier of eight years or the 85th day prior to the maturity date of the FinCo Loan (the "SuperFinCo Loan").
    
    
      •On October 16, 2025, in conjunction with the positive FID on Train 5 at the Rio Grande LNG Facility, we and certain of our subsidiaries closed an approximately $6.7 billion project financing for Train 5, which included the closing of:
    
    
      ◦A joint venture agreement which included approximately $1.29 billion of financial commitments from GIP, GIC, and Mubadala Investment Company;
    
    
      ◦A commitment by the Company to invest approximately $1.29 billion in Train 5;
    
    
      ◦A senior secured, non-recourse bank credit facility of $3.59 billion with a seven year maturity; and
    
    
      ◦An offering of $500 million senior secured, non-recourse private placement notes, which will bear interest at 6.56%, will be funded in multiple tranches from December 2025 through October 2026, and will amortize over a period of 20 years beginning in September 2031.
    
    
      •On October 16, 2025, to fully fund the Company's approximately $1.29 billion equity commitments for Train 5, we contributed $233 million cash to Train 5 LLC, and certain of our wholly-owned subsidiaries increased the size of the FinCo Loan by $729 million, to a total of approximately $1.46 billion, and increased the size of the SuperFinCo Loan by $600 million, to a total of $1.2 billion.
    
    
      •In October 2025, Rio Grande LNG Super Holdings, LLC, entered into a term sheet with the lender of the Super Holdings Loan to refinance $50 million of the existing loan amount and provide $50 million of incremental capital in the form of an exchangeable loan with total initial principal of $100 million (the "Exchangeable Loan"). Upon consummation of the transaction, the Exchangeable Loan would bear interest at 8%, payable in cash or in-kind at the Company's election, and would mature in October 2030. The initial principal of the Exchangeable Loan, and any amounts of interest paid in-kind, would be exchangeable into shares of Company common stock at $9.50 per share. Additionally, the interest rate on the remaining balance of the Super Holdings Loan would be amended to 13.5%.
    
    
      Regulatory
    
    
      •In March 2025, the U.S. Court of Appeals for the D.C. Circuit (the "D.C. Circuit Court") issued a revision to its August 2024 decision regarding the Company's FERC order, resulting in a remand without vacatur of the FERC order for the first five liquefaction trains at the Rio Grande LNG Facility. Pursuant to the remand, FERC was to consider the issue of a supplemental Environmental Impact Statement ("SEIS") in view of several executive orders issued since January 20, 2025.
    
    
      •In July 2025, the FERC issued a final SEIS for the first five liquefaction trains at the Rio Grande LNG Facility, following a draft SEIS in March 2025.
    
    
      •In August 2025, the FERC issued a final order on remand reaffirming its authorization for the siting, construction, and operation of the first five liquefaction trains at the Rio Grande LNG Facility, and as of October 30, 2025, the order is no longer appealable to FERC.
    
    
      Rio Grande LNG Facility Activity
    
    
      Liquefaction Facilities Overview and Construction Progress
    
    
      We are constructing and developing the Rio Grande LNG Facility on the north shore of the Brownsville Ship Channel in south Texas. The site is located on approximately 1,000 acres of land, which has been leased long-term and includes 15,000 feet of frontage on the Brownsville Ship Channel. We believe the site is advantaged due to its proximity to abundant natural gas resources in the Permian
    
    
      
    
    
      Basin and Eagle Ford Shale, access to an uncongested waterway for vessel loading, and location in a region that has historically been subject to fewer and less severe weather events relative to other locations along the U.S. Gulf Coast. Trains 1 through 5 at the Rio Grande LNG Facility are under construction, and we are developing and advancing the permitting process for Trains 6 through 8. There is sufficient space at the Rio Grande LNG Facility site for up to 10 liquefaction trains.
    
    
      Construction commenced on Phase 1 at the Rio Grande LNG Facility in July 2023, on Train 4 in September 2025, and on Train 5 in October 2025, in each case following a positive FID and the closing of project financing by the Company's subsidiaries. Construction will be completed by Bechtel under fully wrapped, lump-sum turnkey EPC contracts, and the liquefaction trains will utilize Honeywell AP-C3MRTMliquefaction technology, which is the predominant liquefaction technology utilized globally.
    
    
      The combined scope of Phase 1, Train 4, and Train 5 includes five liquefaction trains with a total expected LNG production capacity of approximately 30 MTPA, four 180,000 cubic meter full containment LNG storage tanks, two jetty berthing structures designed to load LNG carriers up to 216,000 cubic meters in capacity, and associated site infrastructure and common facilities including feed gas pretreatment facilities, electric and water utilities, ground flares, roads, levees surrounding the entire site, and warehouses, administrative, operations control room and maintenance buildings.
    
    
      As of September 2025, progress on Phase 1 is ahead of schedule under the EPC contracts. During the third quarter of 2025, the construction team continued piping fabrication, rebar installation, equipment setting and concrete placement, and structural steel erection in the areas of Trains 1, 2, and 3. Roof raises were completed for the first two LNG storage tanks. Across the site, Bechtel also continued installing concrete foundations, instrument air receivers, floodgates, permanent fencing, temporary facilities, and other siteworks. In September 2025, the first compressor string and turbine for Train 1 arrived onsite.
    
    
      During September 2025, progress on Train 4 included advancement on engineering drawings, issuance of purchase orders for a range of equipment and materials, and commencement of area clearing.
    
    
      LNG Sale and Purchase Agreements for Trains 1 Through 5
    
    
      We have entered into long-term SPAs with 14 creditworthy counterparties for aggregate volumes of approximately 25.3 MTPA of LNG from Trains 1 through 5 at the Rio Grande LNG Facility. The SPAs have a weighted average term of 19.5 years. Under these SPAs, the customers will purchase LNG from the Rio Grande LNG Facility for a price consisting of a fixed fee per MMBtu of LNG plus a variable fee per MMBtu of LNG, with the variable fees structured to cover the expected cost of natural gas plus fuel and other sourcing costs to produce LNG. In certain circumstances, customers may elect to cancel or suspend deliveries of LNG cargoes, in which case the customers would still be required to pay the fixed fee with respect to cargoes that are not delivered. A portion of the fixed fee under each SPA will be subject to annual adjustment for inflation. The SPAs and contracted volumes to be made available under the SPAs are not tied to a specific train; however, the commencement of the term of each SPA is tied to a specified train.
    
    
      Each of these SPAs is currently effective, and deliveries of LNG under these SPAs will commence on the respective Date of First Commercial Delivery ("DFCD"), which is primarily tied to the substantial completion or guaranteed substantial completion dates of specific trains as defined in each SPA. In aggregate, the approximately 23.75 MTPA of Henry Hub-linked SPAs for Trains 1 through 5 have average fixed fees, unadjusted for inflation, totaling approximately $3.0 billion expected to be paid annually.
    
    
      Marketing of Uncontracted Volumes
    
    
      We expect to sell any commissioning LNG volumes and operational LNG volumes in excess of SPA volumes into the LNG market through spot, short-term, and medium-term agreements. We have entered into certain time charter agreements and expect to enter into additional time charter agreements with vessel owners to provide shipping capacity for LNG sales related to our 1.0 MTPA delivered ex-ship SPA, expected commissioning volumes, and expected portfolio volumes.
    
    
      Engineering, Procurement and Construction ("EPC")
    
    
      We have entered into fully wrapped, lump-sum turnkey contracts with Bechtel, a well-established and reputable LNG engineering and construction firm, for the engineering, procurement, and construction of Phase 1, Train 4, and Train 5 at the Rio Grande LNG Facility, under which Bechtel has generally guaranteed cost, performance, and schedule. Under these EPC contracts, Bechtel is responsible for the engineering, procurement, construction, commissioning, and startup of liquefaction trains and their respective related infrastructure.
    
    
      On July 12, 2023, we issued final notice to proceed to Bechtel under the EPC contracts for Phase 1. Total expected capital costs for Phase 1 are estimated to be approximately $18.0 billion, including estimated EPC costs, owner's costs, contingencies, and financing costs, and including amounts spent prior to FID under limited notices to proceed.
    
    
      On September 9, 2025, we issued final notice to proceed to Bechtel under the EPC contract for Train 4. Total expected capital costs for Train 4 are estimated to be approximately $6.7 billion, including estimated EPC costs, owner's costs, contingencies, financing costs, and other costs, including a payment to be made at the commencement of operations to the trains in commercial operation at such date for Train 4's proportionate share of the capital costs of the common facilities it will access, net of the capital cost of any common facilities constructed under the Train 4 EPC contract.
    
    
      On October 16, 2025, we issued final notice to proceed to Bechtel under the EPC contract for Train 5. Total expected capital costs for Train 5 are estimated to be approximately $6.7 billion, including estimated EPC costs, owner's costs, contingencies, financing costs, and other costs, including a payment to be made at the commencement of operations to the trains in commercial operation at such date for Train 5's proportionate share of the capital costs of the common facilities it will access, net of the capital cost of any common facilities constructed under the Train 5 EPC contract.
    
    
      
    
    
      Natural Gas Transportation and Supply
    
    
      We are in the process of executing a substantial and diversified natural gas feedstock sourcing and transportation strategy to spread risk exposure across multiple contracts, counterparties, and pricing hubs. We expect to enter into gas supply arrangements with a wide range of suppliers, and we also expect to leverage trading platforms and exchanges to lock in natural gas supply prices and/or hedge risk.
    
    
      We have entered into agreements for transportation of natural gas to the Rio Grande LNG Facility on both a firm and interruptible basis to support commissioning and operations and provide the ability to purchase natural gas supplies at the Agua Dulce Hub, giving us access to prolific gas production from the Permian Basin and Eagle Ford Shale and providing significant flexibility to obtain competitively priced natural gas feedstock.
    
    
      We believe our proximity to major reserve basins and shale plays, increasing pipeline capacity in the area, a significant amount of natural gas production and infrastructure investment, as well as our existing contacts and discussions with some of the largest regional operators, represent key elements of a comprehensive and effective feed gas strategy.
    
    
      NextDecade Economic Interest in Trains 1 Through 5
    
    
      Pursuant to a joint venture agreement with equity partners for ownership of Phase 1 at the Rio Grande LNG Facility, we expect to receive up to approximately 20.8% of distributions of available cash generated from Phase 1 operations, provided that a majority of the cash distributions to which we are otherwise entitled will be paid for any distribution period only after our equity partners receive an agreed distribution threshold in respect of such distribution period and certain other deficit payments from prior distribution periods, if any, are made.
    
    
      Pursuant to a joint venture agreement with equity partners for ownership of Train 4 at the Rio Grande LNG Facility, we expect to receive 40% of distributions of available cash generated from Train 4 operations, which will increase to 60% when the equity partners receive a certain return on their investments in Train 4.
    
    
      Pursuant to a joint venture agreement with equity partners for ownership of Train 5 at the Rio Grande LNG Facility, we expect to receive 50% of distributions of available cash generated from Train 5 operations, which will increase to 70% when the equity partners receive a certain return on their investments in Train 5.
    
    
      Development of Additional Liquefaction Capacity
    
    
      We are developing and advancing the permitting process for additional liquefaction capacity at the Rio Grande LNG Facility site. Trains 6 through 8 are currently wholly owned by NextDecade and are cumulatively expected to increase the Company's total liquefaction capacity by approximately 18 MTPA once constructed and placed into operation.
    
    
      Train 6 is being developed inside the existing levee at the Rio Grande LNG Facility site and adjacent to Trains 1 through 5. The Company expects to pre-file an application with FERC for Train 6 in 2025 and a full application with FERC in 2026. The Company is evaluating multiple areas on the site for the development of Trains 7 and 8.
    
    
      There is sufficient space at the Rio Grande LNG Facility site for up to 10 liquefaction trains.
    
    
      Governmental Permits, Approvals and Authorizations
    
    
      We have obtained all major permits required to build and export LNG from the first five liquefaction trains and related infrastructure at the Rio Grande Facility, including FERC approval and Department of Energy FTA and non-FTA authorizations.
    
    
      In March 2025, the D.C. Circuit Court issued a revision to its August 2024 decision regarding our FERC order, resulting in a remand without vacatur of the FERC order for the first five liquefaction trains at the Rio Grande LNG Facility. Pursuant to the remand, FERC was to consider the issue of a supplemental Environmental Impact Statement ("SEIS") in view of several executive orders issued since January 20, 2025.
    
    
      In March 2025, the FERC issued a draft SEIS for the first five liquefaction trains at the Rio Grande LNG Facility. In July 2025, the FERC issued a final SEIS for the first five liquefaction trains at the Rio Grande LNG Facility. In August 2025, the FERC issued a final order on remand reaffirming its authorization for the siting, construction, and operation of the first five liquefaction trains at the Rio Grande LNG Facility. In September 2025, a request for rehearing of the Remand Order was filed by certain intervenors and on October 30, 2025, the rehearing request was deemed denied by operation of law, rendering the Remand Order no longer appealable to FERC.
    
    
      Corporate and Other Activities
    
    
      We are required to maintain corporate and general and administrative functions to serve our business activities described above, including the construction of Trains 1 through 5, the development of Trains 6 through 8, and evaluating the potential development of a CCS project at the Rio Grande LNG Facility.
    
    
      Liquidity and Capital Resources
    
    
      Following FID on Trains 1 through 5 and the project financing obtained by the Company's subsidiaries, Phase 1 LLC, Train 4 LLC, and Train 5 LLC (together, the "Rio Grande Project Entities") operate with independent capital structures. Although our sources and uses are presented from a consolidated standpoint, certain restrictions under debt and equity agreements limit the ability of NextDecade and the Rio Grande Project Entities to use and distribute cash. The Rio Grande Project Entities are required to deposit all
    
    
      
    
    
      cash received under their respective debt agreements into restricted accounts. The usage or withdrawal of such cash is restricted to the payment of obligations related to their respective trains and common infrastructure and other restricted payments, and such cash and capital resources are not available to service the obligations of NextDecade.
    
    
      Phase 1 FID Rio Grande Financing
    
    
      In connection with the FID on Phase 1 at the Rio Grande LNG Facility, Phase 1 LLC obtained approximately $6.2 billion in equity capital commitments, inclusive of commitments from NextDecade, entered into senior secured non-recourse bank credit facilities of $11.6 billion, consisting of $11.1 billion in construction term loans and a $500 million working capital facility, and closed a $700 million senior secured non-recourse private notes offering. Phase 1 LLC expects to utilize these capital resources to fund the total cost of Phase 1, which is currently estimated at $18.0 billion and consists of EPC costs, owner's costs and contingencies, dredging for the Brazos Island Harbor Channel Improvement Project, conservation of more than 4,000 acres of wetland and wildlife habitat area and installation of utilities, interest during construction and other financing costs, and and including amounts spent prior to FID under limited notices to proceed. Phase 1 LLC has refinanced a total of over $1.85 billion of its original $11.1 billion term loan facilities since July 2023 through the issuance of senior secured notes and loans.
    
    
      In April 2025, Phase 1 LLC elected to terminate $250 million of commitments under its working capital facility due to a decrease in expected requirements for credit support during construction, which reduced the outstanding commitments under the working capital facility to $250 million.
    
    
      Train 4 FID Rio Grande Train 4 Financing
    
    
      In connection with the FID on Train 4 at the Rio Grande LNG Facility, Train 4 LLC obtained approximately $2.8 billion in equity capital commitments, inclusive of commitments from NextDecade, and entered into a senior secured non-recourse bank credit facility of approximately $3.9 billion. Train 4 LLC expects to utilize these capital resources to fund the total cost of Train 4 and related infrastructure, which is currently estimated at $6.7 billion and consists of EPC costs, owner's costs and contingencies, interest during construction and other financing costs, and other costs, including a payment for usage of common infrastructure at the Rio Grande LNG Facility.
    
    
      Train 5 FID Rio Grande Train 5 Financing
    
    
      In connection with the FID on Train 5 at the Rio Grande LNG Facility, Train 5 LLC obtained approximately $2.6 billion in equity capital commitments, inclusive of commitments from NextDecade, entered into a senior secured non-recourse bank credit facility of approximately $3.6 billion, and closed a $500 million senior secured non-recourse private notes offering. Train 5 LLC expects to utilize these capital resources to fund the total cost of Train 5 and related infrastructure, which is currently estimated at $6.7 billion and consists of EPC costs, owner's costs and contingencies, interest during construction and other financing costs, and other costs, including a payment for usage of common infrastructure at the Rio Grande LNG Facility.
    
    
      Near Term Liquidity and Capital Resources of NextDecade Corporation
    
    
      Following the respective FIDs of Phase 1, Train 4 and Train 5, costs associated with the EPC agreements, Rio Grande site lease, and other Phase 1, Train 4, and Train 5 related costs are being funded by debt and equity proceeds received by the Rio Grande Project Entities. Our primary corporate cash needs are capital contributions to Trains 4 and 5, development expenses for expansion projects and general and administrative expenses.
    
    
      In connection with the FIDs of Train 4 and Train 5, we committed to make approximately $2.4 billion in equity capital contributions for Train 4 and 5 in the aggregate. At the FIDs of Train 4 and Train 5, we used the net proceeds of the Super FinCo Loans and cash on hand to fund a portion of our equity commitments for Train 4 and Train 5. We will fund the remainder of our equity commitments to Trains 4 and 5 using borrowings under the FinCo Credit Agreement.
    
    
      At Train 4 FID, Train 4 LLC paid NextDecade LLC, our wholly owned subsidiary and the entity that manages the construction, commissioning and operation of the Rio Grande Facility on behalf of Phase 1, Train 4 and Train 5, $98 million, representing a $48 million development fee for activities prior to FID of Train 4 and a $50 million fee for services to be rendered by NextDecade LLC in support of Train 4. Train 4 LLC will also pay NextDecade LLC an additional $50 million services fee in September 2026. At Train 5 FID, Train 5 LLC paid NextDecade LLC $117 million, representing a $17 million development fee for activities prior to FID of Train 5 and a $100 million fee for services to be rendered by NextDecade LLC in support of Train 5.
    
    
      Because our businesses and assets are under construction or in development, we have not historically generated significant cash flow from operations, and we do not expect to do so until liquefaction trains at the Rio Grande LNG Facility begin operating. We intend to fund development activities for the foreseeable future with our cash and cash equivalents on hand, the services fee due in September 2026 and through the sale of additional equity, equity-based or debt securities in us or in our subsidiaries. There can be no assurance that we will succeed in selling such securities or, if successful, that the capital we raise will not be expensive or dilutive to stockholders.
    
    
      Long Term Liquidity and Capital Resources of NextDecade Corporation
    
    
      We will not receive significant cash flows from liquefaction trains at the Rio Grande LNG Facility until they are operational, and the commercial operation date for the first train is expected to occur in late 2027 based on the guaranteed schedule under the EPC contracts. Any future development of liquefaction trains and any potential CCS project at the Rio Grande LNG Facility will similarly take an extended period of time to develop, construct and become operational and will require significant capital deployment.
    
    
      
    
    
      We currently expect that the long-term capital requirements for future development of liquefaction trains and any potential CCS project at the Rio Grande LNG Facility will be financed predominantly through the proceeds from future debt, equity-based, and equity offerings by us or our subsidiaries. As a result, our business success will depend, to a significant extent, upon our ability to obtain financing required to fund future development and construction at the Rio Grande LNG Facility, to bring assets into operation on a commercially viable basis and to finance any required increases in staffing, operating and expansion costs during that process. There can be no assurance that we will succeed in securing additional debt and/or equity financing in the future to fund future development and construction at the Rio Grande LNG Facility or, if successful, that the capital we raise will not be expensive or dilutive to stockholders. Additionally, if these types of financing are not available, we will be required to seek alternative sources of financing, which may not be available on terms acceptable to us, if at all.

      Cash used in operating activities for the nine months ended September 30, 2025 increased by approximately $62.1 million compared to the same period in 2024 primarily due to higher pre-operational expenditures and working capital investments to support the commencement of operations at the Rio Grande LNG Facility.
    
    
      Cash used in investing activities for the nine months ended September 30, 2025 increased by approximately $1.0 billion compared to the same period in 2024 primarily due to increased expenditures associated with construction of the Rio Grande LNG Facility.
    
    
      Cash provided by financing activities for the nine months ended September 30, 2025 increased by approximately $1.4 billion compared to the same period in 2024. This was driven by an increase of approximately $217.3 million uptick in equity commitment receipts and the absence of approximately $1.3 billion of debt repayments in the current period.

      Net loss attributable to common stockholders was approximately $109.5 million, for the three months ended September 30, 2025 compared to net loss of approximately $123.2 million during the same period in 2024. The approximately $13.7 million decrease was primarily a result of the following:
    
    
      
    
    
      •General and administrative expenses increased by approximately $22.5 million, principally reflecting higher share-based compensation expense recognized in connection with FID on Train 4 and incremental headcount additions to support the commencement of operations at the Rio Grande LNG Facility.
    
    
      •The change in derivative (loss) gain of approximately $255.6 million was primarily driven by lower forward SOFR rates, which reduced the mark-to-market loss on the Company's interest rate swap portfolio.
    
    
      •Interest expense, net increased by approximately $22.7 million primarily due to additional borrowings to construct the Rio Grande LNG Facility.
    
    
      •Due to the above changes, net loss attributable to non-controlling interest for the three months ended September 30, 2025, decreased by approximately $194.6 million, reflecting the impact of derivative gains and interest expense recognized within Phase 1 Holdings, which are consolidated in the Company's results.
    
    
      Net loss attributable to common stockholders was approximately $259.2 million, for the nine months ended September 30, 2025 compared to net loss of approximately $127.4 million during the same period in 2024. The approximately $131.7 million increase was primarily a result of the following:
    
    
      •General and administrative expenses increased by approximately $53.1 million, principally reflecting higher share-based compensation expense recognized in connection with FID on Train 4 and incremental headcount additions to support the commencement of operations at the Rio Grande LNG Facility.
    
    
      •The change in derivative (loss) gain of approximately $255.9 million for the nine months ended September 30, 2025, was primarily driven by lower forward SOFR rates, which increased the fair-value loss on the Company's interest rate swap portfolio.
    
    
      •Loss on debt extinguishment decreased approximately $38.4 million due to the lack of debt repayments during the current period.
    
    
      •Interest expense, net increased by approximately $27.3 million primarily due to additional borrowings to construct the Rio Grande LNG Facility.
    
    
      •Due to the above changes, net loss attributable to non-controlling interest for the nine months ended September 30, 2025, increased by approximately $164.9 million, reflecting the impact of derivative losses and interest expense recognized within Phase 1 Holdings, which are consolidated in the Company's results.
