Exhibit 99.1

BKV Corporation

Unaudited Pro Forma Condensed Combined Financial Information

On September 29, 2025, BKV Upstream Midstream, LLC (“BKV Upstream Midstream”), a Delaware limited liability company and a wholly owned subsidiary of BKV Corporation, a Delaware corporation (“BKV” or the “Company”), completed the acquisition of 100% of the equity interests (the “Subject Interests”) of Bedrock Production, LLC, a Texas limited liability company (the “Target”), from Bedrock Energy Partners, LLC, a Delaware limited liability company (“Seller”) and certain of its subsidiaries (such transaction, the “Bedrock Acquisition”). The Bedrock Acquisition was completed pursuant to the Membership Interest Purchase Agreement, dated August 7, 2025 (the “Purchase Agreement”), by and among BKV Upstream Midstream, Seller and certain of its subsidiaries, and solely for certain limited purposes set forth therein, BKV.

The Target and its subsidiaries own certain oil and natural gas producing properties in the Barnett Shale. Following the closing, the Target is a wholly-owned subsidiary of BKV Upstream Midstream. Additionally, the Target and its subsidiaries have executed an assumption agreement in order to be added as guarantors and collateral grantors under BKV’s existing reserve-based lending agreement.

The aggregate consideration paid (or to be paid) to the Seller in the Bedrock Acquisition is $397.7 million (the “Purchase Price”), subject to customary adjustments, including, but not limited to estimated fair value of assets acquired and liabilities assumed. Pursuant to the Purchase Agreement, at the closing of the Bedrock Acquisition, BKV paid a portion of the Purchase Price consisting of (i) the Deposit (described below), (ii) approximately $179.5 million in cash to repay certain Target indebtedness, and (iii) the issuance to Seller of 5,233,957 shares of BKV common stock (the “Stock Consideration” and clauses (i) to (iii), collectively, the “Purchase Consideration Transactions”). The remainder of the Purchase Price of $53.1 million, subject to customary adjustments, as noted above, will be paid in cash by December 31, 2025.

As of September 29, 2025, the fair market value of the Stock Consideration was approximately $124.2 million based on the closing price of $23.74.

On August 8, 2025, BKV deposited 10% of the unadjusted Purchase Price (the “Deposit”) into a third-party escrow account. At the closing of the Bedrock Acquisition, the Deposit was retained as a holdback for any BKV indemnification claims until released on the terms and conditions contained in the Purchase Agreement.

BKV funded the cash consideration paid at the closing of the Bedrock Acquisition, and expects to fund the remainder of the Purchase Price, with a combination of the proceeds from the offering by BKV Upstream Midstream of $500,000,000 in aggregate principal amount of 7.500% senior unsecured notes due 2030 (the “2030 Senior Notes”), borrowings under BKV’s existing reserve-based lending agreement (the “RBL Credit Agreement”), and cash on hand. A portion of the borrowings under the 2030 Senior Notes was used to pay down $200.0 million of the RBL Credit Agreement balance (collectively, the “Financing Transactions”).

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.”

The historical financial statements of BKV and the unaudited books and records of the Target have been adjusted in the accompanying unaudited pro forma condensed combined financial information to give effect to the Bedrock Acquisition, the Purchase Consideration Transactions, and the Financing Transactions. The unaudited pro forma condensed combined financial information includes adjustments to account for the Bedrock Acquisition and the Purchase Consideration Transactions in accordance with U.S. GAAP as of the dates indicated (collectively, the “Acquisition Accounting Adjustments”). The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2025, gives effect to the Bedrock Acquisition and the Purchase Consideration Transactions as if they had occurred on January 1, 2024. The unaudited pro forma adjustments are based upon available information and certain assumptions that BKV’s management believes are reasonable.

The unaudited pro forma condensed combined financial information should be read in conjunction with the following:

The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2025, has been prepared for illustrative purposes only and is not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the Bedrock Acquisition occurred as of the dates indicated. The unaudited pro forma condensed combined statement of operations also should not be considered indicative of the future results of operations or financial position of BKV. An unaudited pro forma condensed combined balance sheet of the Company is not presented as of September 30, 2025, as the Company’s condensed consolidated balance sheet as of September 30, 2025 already reflects the consummated Bedrock Acquisition.

BKV Corporation Notes to Pro Forma Condensed Combined Financial Information

Note 1 - Basis of Presentation

The accompanying unaudited pro forma condensed combined financial information was derived from the historical financial statements of BKV Corporation for the nine months ended September 30, 2025, and the unaudited books and records of Bedrock Energy Partners, LLC (“Bedrock Partners”) from January 1, 2025, through September 29, 2025.

Note 2 - Pro Forma Purchase Price Allocation

The Bedrock Acquisition was accounted for as an asset acquisition as the fair value of substantially all the assets acquired were concentrated in a group of similar assets. Transaction costs incurred to acquire the assets, which amounted to $3.8 million, were capitalized and included in the cost basis of the acquired assets. The Company expects to complete the purchase price assessment by December 31, 2025, which is when the remainder of the purchase price consideration of approximately $53.1 million, subject to customary adjustment, is due. The stock consideration paid to Seller for the Bedrock Acquisition was valued at $124.3 million on the date of issuance (at closing) resulting in an aggregate value of consideration paid (or to be paid) to the Seller of $397.7 million, subject to customary adjustments, including, but not limited to estimated fair value of assets acquired and liabilities assumed. This purchase price allocation is reflected in the condensed consolidated balance sheet of BKV Corporation’s Quarterly Report on Form 10-Q as of September 30, 2025, as filed November 10, 2025.

Below is a reconciliation of the assets acquired and liabilities assumed (in thousands):

Note 3 - Adjustments to Unaudited Pro Forma Combined Consolidated Financial Statements

(b) Reflects the pro forma adjustments to record the depletion and accretion expenses calculated in accordance with BKV Corporation’s depletion rate.

(c) Increase of $7.6 million was comprised of (i) $28.1 million interest expense, including amortization of debt issuance costs, on BKV's $500 million 5-year senior notes with a weighted average interest rate of 7.50%, and (ii) $2.0 million estimated fees, less (iii) $12.4 million of interest expense on Bedrock Partners' debt that is not part of the Bedrock Acquisition, and (iv) $10.1 million interest expense savings from paying down $200.0 million on the RBL Credit Agreement balance.

(d) Income tax benefit of $3.0 million was comprised of (i) $2.8 million tax benefit impact on the financing and acquisition adjustments using a statutory rate of 23% and (ii) the elimination of $0.2 million of Bedrock Partners' income tax expense.

(e) Reflects the September 29, 2025 issuance of 5.2 million shares of BKV Corporation’s common stock to the holders of the Bedrock Interests to partially finance the Bedrock Acquisition at $23.74 per share, for total stock consideration of $124.3 million.

Note 4 - Earnings per Share

Basic net income attributable to BKV per common share for each period is calculated by dividing net income attributable to BKV by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share is calculated by dividing net income attributable to BKV by the diluted weighted average number of common shares outstanding for the respective period. Any remeasurement of the accretion to redemption value of the Class B Units subject to possible redemption was considered to be dividends paid to the noncontrolling interest. Diluted weighted average number of common shares outstanding and the dilutive effect of potential common shares is calculated using the treasury method. The Company includes potential shares of common stock for PRSUs and TRSUs in the calculation of diluted weighted average shares outstanding based on the number of common shares that would be issuable if the end of the reporting period was also the end of the performance period. During periods in which the Company incurred a net loss, diluted weighted average common shares outstanding were equal to basic weighted average of common shares outstanding because the effects of all potential common shares was anti-dilutive.

The following table presents the historical and pro forma calculation of basic and diluted net income per common share attributable to BKV for the nine months ended September 30, 2025:
