NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2024

NOTE 1 – BASIS OF PRESENTATION

These interim Condensed Consolidated Financial Statements of Babcock & Wilcox Enterprises, Inc. (“B&W,” “management,” “we,” “us,” “our” or the “Company”) have been prepared in accordance with GAAP and SEC instructions for interim financial information, and should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2023. The Notes to Condensed Consolidated Financial Statements are presented on the basis of continuing operations, unless otherwise stated.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these Condensed Consolidated Financial Statements contain all estimates and adjustments, consisting of normal recurring adjustments, required to fairly present the financial position, results of operations, and cash flows for the periods presented. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2024.

There have been no material changes to our significant accounting policies included in the Annual Report on Form 10-K for the year ended December 31, 2023.

Non-controlling interests are presented in the Condensed Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (non-controlling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in non-controlling interests are reported as equity in the Condensed Consolidated Financial Statements. Additionally, the Condensed Consolidated Financial Statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and non-controlling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control.

Liquidity and Going Concern

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

We have recurring operating losses primarily due to losses recognized on our B&W Solar business as described in Note 4 to the Consolidated Financial Statements included in Part II, Item 8 of our Form 10-K filed on March 15, 2024 as well as higher debt service costs. Our assessment of our ability to fund future operations is inherently subjective, judgment-based and susceptible to change based on future events. Currently, with existing cash on hand and available liquidity, we are projecting insufficient liquidity to fund operations through one year following the date that this Quarterly Report is issued. These conditions and events raise substantial doubt about our ability to continue as a going concern.

In response to the conditions, we are implementing several strategies to obtain the required funding for future operations and are considering other alternative measures to improve cash flow, including suspension of the dividend on our Preferred Stock. The following actions occurred during the three months ended March 31, 2024:

•entered into advanced negotiations related to the sale of one of our non-strategic businesses. Proceeds from the sale are expected to be approximately $40.0 million to $46.0 million, subject to due diligence and continuing negotiations. We cannot provide any assurances that such transaction will close or that proceeds will not be more or less than we anticipate;

•initiated the process to sell certain of our other non-strategic businesses;

•filed for a waiver of required minimum contributions to the Retirement Plan for Employees of Babcock & Wilcox Commercial Operations (the "U.S. Plan"), that if granted, would reduce cash funding requirements in 2024 and would increase contributions annually over the subsequent five-year period. We cannot provide any assurances that such waiver will be granted;

•initiated the process to sell several non-core real estate assets;

•initiated the sale of common shares pursuant to our At-The-Market Offering; and

•negotiated the settlement of a liability to the former owner of B&W Solar at a discount, resulting in future cash savings of $7.2 million.

Based on our ability to raise funds through the actions noted above and our Cash and cash equivalents as of March 31, 2024, we have concluded it is probable that such actions would provide sufficient liquidity to fund operations for the next twelve months following the date of this Quarterly Report. As a result, it is probable that our cash flow improvement plans and anticipated proceeds from the sale of non-strategic assets alleviate the substantial doubt about our ability to continue as a going concern.

Operations

Our operations are assessed based on three reportable market-facing segments consistent with our strategic initiative to accelerate growth and provide stakeholders improved visibility into our renewable and environmental growth platforms. Our reportable segments are as follows:

•Babcock & Wilcox Renewable: Technologies for efficient and environmentally sustainable power and heat generation, including waste-to-energy, biomass-to-energy and black liquor systems for the pulp and paper industry. Our technologies support a circular economy, diverting waste from landfills to use for power generation and replacing fossil fuels, while recovering metals and reducing emissions.

•Babcock & Wilcox Environmental: A full suite of emissions control and environmental technology solutions for utility, waste-to-energy, biomass-to-energy, carbon black, and industrial steam generation applications around the world. Our broad experience includes systems for cooling, ash handling, particulate control, nitrogen oxides and sulfur dioxides removal, chemical looping for carbon control, and mercury control.

•Babcock & Wilcox Thermal: Steam generation equipment, aftermarket parts, construction, maintenance and field services for plants in the power generation, oil and gas, and industrial sectors. We have an extensive global base of installed equipment for utilities and general industrial applications including refining, petrochemical, food processing, metals and others.

For financial information about our segments see Note 4 to the Condensed Consolidated Financial Statements.

NOTE 2 – LOSS PER SHARE

The following table sets forth the computation of basic and diluted loss per share of our common stock, net of non-controlling interest and dividends on preferred stock:


	Three Months Ended March 31,
(in thousands, except per share amounts)	2024		2023
Loss from continuing operations	$	(15,799)	$	(12,686)
Net loss attributable to non-controlling interest	(42)		(21)
Less: Dividend on Series A preferred stock	3,714		3,715
Loss from continuing operations attributable to stockholders of common stock	(19,555)		(16,422)
(Loss) income from discontinued operations, net of tax	(992)		211
Net loss attributable to stockholders of common stock	$	(20,547)	$	(16,211)



Weighted average shares used to calculate basic and diluted loss per share	89,479		88,733

Basic and diluted loss per share:
Continuing operations	$	(0.22)	$	(0.18)
Discontinued operations	(0.01)		$	—
Basic and diluted loss per share	$	(0.23)	$	(0.18)

Basic and diluted weighted average shares are the same because we incurred a net loss in the three months ended March 31, 2024 and 2023.

For the three months ended March 31, 2024 if we had net income, we would have had no additional dilutive shares. If we had net income for the three months ended March 31, 2023 we would have included 0.4 million in diluted shares.

We would have excluded 2.4 million and 2.2 million shares related to stock options from the diluted share calculation for the three months ended March 31, 2024 and 2023, respectively, because their effect would have been anti-dilutive.

NOTE 3 - ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS

During the third quarter of 2023, we committed to a plan to sell our B&W Solar business resulting in a significant change that would impact our operations. As of September 30, 2023, we met all of the criteria for the assets and liabilities of this business, formerly part of our B&W Renewable segment, to be accounted for as held for sale. In addition, we also determined that the operations of the B&W Solar business qualified as a discontinued operation, primarily based upon its significance to our current and historic operating losses.

We continued to meet the criteria to account for the B&W Solar business as held for sale and discontinued operations as of March 31, 2024.

The following table summarizes the operating results of the disposal group included in discontinued operations in the Condensed Consolidated Statements of Operations:

Contracts

During the three months ended March 31, 2024, seven contracts were terminated, resulting in gross profit of $1.2 million. There were no new loss contracts during the three months ended March 31, 2024. During the three months ended March 31, 2023, one B&W Solar project became a loss contract, and the related loss was immaterial to the condensed consolidated financial statements.

Changes in Contract Estimates

During the three months ended March 31, 2024 and 2023 B&W Solar recognized changes in estimated gross profit related to long-term contracts accounted for on the over time basis, which are summarized below:


	Three Months Ended March 31,
(in thousands)	2024		2023
Increases in gross profit for changes in estimates (1)	$	2,212	$	824
Decreases in gross profit for changes in estimates	(147)		(1,510)
Net changes in gross profit for changes in estimates	$	2,065	$	(686)

(1) Includes the $1.2 million contract termination benefit noted above.

Backlog

B&W Solar backlog was $72.4 million and $99.0 million at March 31, 2024 and December 31, 2023, respectively. The decrease was primarily driven by contract terminations of $17.0 million and revenue recognized of $11.4 million, partially offset by new bookings during the quarter. We expect to recognize substantially all of the remaining performance obligations as revenue during the year ended December 31, 2024.

NOTE 4 – SEGMENT REPORTING

We assess our operations based on three reportable segments as described in Note 1 to the Condensed Consolidated Financial Statements. An analysis of our operations by segment is as follows:


	Three Months Ended March 31,
(in thousands)	2024		2023
Revenues:
B&W Renewable segment
B&W Renewable	$	29,590	$	49,132

Total Revenues	$	207,556	$	241,258

At a segment level, the adjusted EBITDA presented below is consistent with the manner in which our chief operating decision maker ("CODM") reviews the results of operations and makes strategic decisions about the business and is calculated as earnings before interest, tax, depreciation and amortization adjusted for items such as gains or losses arising from the sale of non-income producing assets, net pension benefits, restructuring activities, impairments, gains and losses on debt extinguishment, legal and settlement costs, costs related to financial consulting, research and development costs, product development costs, costs and operating income from contracts being terminated, and other costs that may not be directly controllable by segment management and are not allocated to the segment. The following table is provided to reconcile our segment performance metrics to loss before income tax expense.


	Three Months Ended March 31,
(in thousands)	2024		2023(1)

B&W Renewable segment adjusted EBITDA	$	1,658	$	4,322

(1) Certain 2023 amounts have been reclassified in the reconciliation to conform to the 2024 presentation.

We do not separately identify or report assets by segment as our CODM does not consider assets by segment to be a critical measure by which performance is measured.

NOTE 5 – REVENUE RECOGNITION AND CONTRACTS

Revenue Recognition

We generate the vast majority of our revenues from the supply of, and aftermarket services for, steam-generating, environmental and auxiliary equipment. We also earn revenue from the supply of custom-engineered cooling systems for steam applications and related aftermarket services.

A performance obligation is a contractual promise to transfer a distinct product or service to the customer. A contract's transaction price is allocated to each distinct performance obligation and is recognized as revenue when (point in time) or as (over time) the performance obligation is satisfied.

Revenue from products and services transferred to customers at a point in time, which includes certain aftermarket parts and services, accounted for 22% and 17% of revenue for the three months ended March 31, 2024 and 2023, respectively. Revenue from products and services transferred to customers over time, which primarily relates to customized, engineered solutions and construction services, accounted for 78% and 83% of revenue for the three months ended March 31, 2024 and 2023, respectively.

Refer to Note 4 to the Condensed Consolidated Financial Statements for further disaggregation of revenue.

Revolving and Letter of Credit Agreements with Axos

We entered into a credit agreement in January 2024, with certain of our subsidiaries as guarantors, the lenders party thereto from time to time and Axos, as administrative agent, swingline lender and letter of credit issuer (the "Credit Agreement").

The Credit Agreement provides for an up to $150.0 million asset-based revolving credit facility (with availability subject to a borrowing base calculation) ("Credit Facility"), including a $100.0 million letter of credit sublimit. Our obligations under the

Credit Agreement are guaranteed by certain of our domestic and foreign subsidiaries. B. Riley has provided a guaranty of payment with regard to our obligations under the Credit Agreement, as further described below. We used and expect to use the proceeds and letter of credit availability under the Credit Agreement to (i) pay off our prior revolving credit facility with PNC, (ii) provide for working capital needs, (iii) provide cash collateral to secure letters of credit to be issued under the Credit Agreement, and (iv) provide for general corporate purposes.

The Credit Agreement has a maturity date of January 18, 2027, provided that if as of August 30, 2025 the 8.125% Senior Notes and 6.50% Senior Notes have not been refinanced pursuant to a Permitted Refinancing, as defined in the Credit Agreement, or the maturity date has not otherwise been extended to a date on or after July 18, 2027, then the maturity date of the Credit Agreement is August 30, 2025.

The interest rates applicable under the Credit Agreement are: (i) with respect to SOFR Loans, (a) SOFR plus 5.25% if the outstanding principal amount of loans is equal to or less than $100.0 million or (b) SOFR plus 4.00% if the outstanding principal amount of loans is equal to or greater than $100.0 million; (ii) with respect to Base Rate Loans, the greater of (a) the Federal Funds Rate plus 2.00% plus the Applicable Margin, (b) the prime rate as designated by Axos plus the Applicable Margin, and (c) Daily Simple SOFR plus 1.00% plus the Applicable Margin; and (iii) with respect to the default rate under the Credit Agreement, the then-existing interest rate plus 2.00%.

In connection with the Credit Agreement, we are required to pay (i) an origination fee of $1.5 million, (ii) a commitment fee equal to 0.50% per annum multiplied by the positive difference by which the Aggregate Revolving Commitments exceed the Total Revolvings Outstanding (as defined in the Credit Agreement), subject to adjustment, (iii) a facility fee equal to the Applicable Margin for SOFR Loans multiplied by the positive difference by which the actual daily amount of L/C Obligations the Administrative Agent is then holding Specified Cash Collateral exceeds the actual daily Outstanding Amount of Revolving Loans, and (iv) a collateral monitoring fee of $1,000 per month. We are permitted to prepay all or any portion of the loans under the Credit Agreement prior to maturity subject to the payment of an early termination fee. The Credit Agreement requires mandatory prepayments under certain circumstances, including in the event of an overadvance.

The obligations under the Credit Agreement are secured by substantially all assets of B&W and each of the guarantors, in each case subject to intercreditor arrangements. The Credit Agreement contains certain representations and warranties, affirmative covenants, negative covenants and conditions that are customarily required for similar financings. The Credit Agreement requires us to comply with certain financial maintenance covenants, including a quarterly fixed charge coverage test, a quarterly total net leverage ratio test, a cash repatriation covenant, a minimum liquidity covenant, an annual cap on maintenance capital expenditures and a limit on unrestricted cash.

The Credit Agreement also contains customary events of default (subject, in certain instances, to specified grace periods) including, but not limited to, the failure to make payments of interest or premium, if any, on, or principal under the Credit Agreement, the failure to comply with certain covenants and agreements specified in the Credit Agreement, defaults in respect of certain other indebtedness, and certain events of insolvency. If any event of default occurs, Axos may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding amounts under the Credit Agreement may become due and payable immediately. At March 31, 2024, we are in compliance with all financial and other covenants contained in the Credit Agreement.

In connection with our entry into the Credit Agreement, we entered into with B. Riley (i) a guaranty agreement in favor of (a) Axos, in its capacity as administrative agent under the Credit Agreement, for the ratable benefit of the Secured Parties and (b) such Secured Parties (the “B. Riley Guaranty”) and (ii) a fee and reimbursement agreement, made by B. Riley and accepted and agreed to by us (the “B. Riley Fee Agreement”). The B. Riley Guaranty provides for the guarantee of all of our obligations under the Credit Agreement. The B. Riley Guaranty is enforceable in certain circumstances, including, among others, certain events of default and the acceleration of our obligations under the Credit Agreement. The B. Riley Fee Agreement provides, among other things, for an annual fee to be paid to B. Riley by us in an annual amount equal to 2.00% of Aggregate Revolving Commitments under the Credit Agreement (or approximately $3 million) as consideration for B. Riley’s agreements and commitments under the B. Riley Guaranty. The B. Riley Fee Agreement also requires us to reimburse B. Riley to the extent the B. Riley Guaranty is called upon by the agent or lenders under the Credit Agreement and requires us to execute a junior secured promissory note with respect to the same within 60 days after the execution of the B. Riley Fee Agreement (or such other date as B. Riley may agree to).

the Increased Inventory Period commences on April 30 and ends on July 31 and would provide approximately $6.0 million additional available borrowings under the Credit Agreement. The Increased Inventory Period is available to us upon our election in subsequent years (subject to a $75,000 fee if we make such an election) and commences on March 1 and ends on July 31.

At March 31, 2024, we had a total of $90.1 million outstanding on the Axos Credit Agreement, which includes $36.8 million drawn on the revolving credit portion of the facility and $53.3 million drawn on the letter of credit portion. At March 31, 2024, cash collateralizing the letters of credit totaling $53.3 million is classified as Restricted cash, of which $11.9 million is classified as current and $41.4 million as long-term.

As of March 31, 2024, Loans payable in the Condensed Consolidated Balance Sheets totaled $103.2 million, net of debt issuance costs of $0.5 million, of which $4.5 million is classified as current and $98.7 million as long-term loans payable in the Consolidated Balance Sheets. In addition to the amounts outstanding on our revolving debt facilities, Loans payable also includes $12.1 million, net of debt issuance costs of $0.5 million, related to sale-leaseback financing transactions.

As of December 31, 2023, we had Loans payable of $41.6 million, net of debt issuance costs of $0.5 million, of which $6.2 million is classified as current and $35.4 million as long-term loans payable in the Consolidated Balance Sheets. Included in these amounts was approximately $12.3 million, net of debt issuance costs of $0.5 million, related to sale-leaseback financing transactions.

Revolving and Letter of Credit Agreements with PNC and MSD

In June 2021, we entered into a Revolving Credit Agreement (the “Revolving Credit Agreement”) with PNC, as administrative agent and a letter of credit agreement (the “Letter of Credit Agreement”) with PNC, pursuant to which PNC agreed to issue up to $110.0 million in letters of credit that is secured in part by cash collateral provided by MSD, as well as a reimbursement, guaranty and security agreement with MSD, as administrative agent, and the cash collateral providers from time to time party thereto, along with certain of our subsidiaries as guarantors, pursuant to which we are obligated to reimburse MSD and any other cash collateral provider to the extent the cash collateral provided by MSD and any other cash collateral provider to secure the Letter of Credit Agreement is drawn to satisfy draws on letters of credit (the “Reimbursement Agreement” and collectively with the Revolving Credit Agreement and Letter of Credit Agreement, the “Debt Facilities”). Our obligations under the Debt Facilities were guaranteed by certain of our existing and future domestic and foreign subsidiaries. B. Riley, a related party, provided a guaranty of payment with regard to our obligations under the Reimbursement Agreement. The Debt Facilities were effectively replaced by the Axos Credit Agreement in January 2024. The Revolving Credit Agreement was terminated in connection with our entry into the Axos Credit Agreement and we are transitioning letters of credit outstanding under the Letter of Credit Agreement and Reimbursement Agreement to the Axos Credit Agreement. We believe all outstanding letters of credit will be transitioned to the Axos Credit Agreement by June 30, 2024, at which time the Letter of Credit Agreement and Reimbursement Agreement is expected to be terminated. We recognized a Loss on debt extinguishment of $5.1 million in the three months ended March 31, 2024 related to the write-off of unamortized deferred financing fees on the Revolving Credit Agreement.

The Letter of Credit Agreement requires fees on outstanding letters of credit equal to (i) administrative fees of 0.75% and (ii) fronting fees of 0.25%. Prepayments under the Reimbursement Agreement are subject to a prepayment fee of 2.25% in the first year after closing, 2.0% in the second year after closing and 1.25% in the third year after closing with no prepayment fee payable thereafter. We have mandatory prepayment obligations under the Reimbursement Agreement upon the receipt of proceeds from certain dispositions or casualty or condemnation events.

The obligations under the Debt Facilities are secured by substantially all of our assets and each of the guarantors, in each case subject to inter-creditor arrangements. As noted above, the obligations under the Letter of Credit Facility are also secured by the cash collateral provided by MSD and any other cash collateral provider thereunder.

The Debt Documents contain certain representations and warranties, affirmative covenants, negative covenants and conditions that are customarily required for similar financings. The Debt Documents also contain customary events of default (subject, in certain instances, to specified grace periods) including, but not limited to, the failure to make payments of interest or premium, if any, on, or principal under the respective facility, the failure to comply with certain covenants and agreements specified in the applicable debt agreement, defaults in respect of certain other indebtedness and certain events of insolvency. If any event of default occurs, the principal, premium, if any, interest and any other monetary obligations on all then-outstanding amounts under the Debt Facilities may become due and payable immediately.

In November 2023, we entered into Amendment No. 3 to the Reimbursement Agreement (the “Third Amended Reimbursement Agreement”), which modified certain financial maintenance covenants for future periods beginning with the fiscal quarter ended on September 30, 2023. The Third Amended Reimbursement Agreement also imposed a leverage condition to the payment of dividends on preferred equity, which required us to provide a quality of earnings report and pay a $1.0 million fee to MSD prior to paying a dividend for the fiscal quarter ending December 31, 2023. The interest rates applicable to the Third Amended Reimbursement Agreement float at a rate per annum equal to SOFR plus 10% through December 31, 2023, SOFR plus 11% from January 1, 2024 through June 30, 2024 and will increase by 50 basis points as of the first day of each fiscal quarter thereafter.

In March 2024, we entered into Amendment No. 4 to the Reimbursement Agreement (the "Fourth Amended Reimbursement Agreement"), which modified certain financial maintenance covenants for periods beginning with the fiscal quarter ended on December 31, 2023. The Fixed Charge Coverage Ratio was amended to 0.93 to 1.0 for the fiscal quarter ending December 31, 2023, 0.82 to 1.0 for the fiscal quarter ending March 31, 2024, 0.90 to 1.0 for the fiscal quarter ending June 30, 2024, 0.95 to 1.0 for the fiscal quarter ending September 30, 2024, 1.1 to 1.0 for the fiscal quarter ending December 31, 2024, and 1.25 to 1.0 for the fiscal quarter ending March 31, 2025 and thereafter. The Senior Net Leverage Ratio condition to payment of any Permitted Restricted Payments, as defined in the Fourth Amended Reimbursement Agreement, was amended to 1.45 to 1.0 for the four quarter fiscal measurement period ending as of December 31, 2023 and 1.25 to 1.0 thereafter. The Fourth Amended Reimbursement Agreement also amends the minimum cash flow covenants set forth in the Reimbursement Agreement to no less than $10.0 million as of December 31, 2023 (for the preceding fiscal quarter), no less than $15.0 million as of December 31, 2024 (for the preceding fiscal year), and no less than $25.0 million as of December 31 of each fiscal year thereafter. The Applicable Margin with respect to Delayed Draw Term Loans and Cash Collateral Commitment Fees will increase by an additional 0.50% on each of April 30, 2024, July 1, 2024, October 1, 2024, January 1, 2025 and April 1, 2025 in each case if the Obligations are in excess of $15 million on the applicable date. At March 31, 2024, we are in compliance with all financial and other covenants contained in the Letter of Credit Agreement and Reimbursement Agreement.

A summary of usage of letters of credit under the domestic facilities is as follows. Due to the timing of the transition of our Letter of Credit Arrangements from PNC and MSD to Axos, balances as of March 31, 2024 are primarily with Axos and balances as of March 31, 2023 are with PNC and MSD.


	March 31,
	2024		2023
Letters of credit under domestic facilities:
Performance letters of credit	$	68,059	$	93,213
Financial letters of credit	11,511		13,648
Total outstanding	$	79,570	$	106,861




Backstopped letters of credit	$	17,169	$	32,397
Surety backstopped letters of credit	$	15,329	$	14,149
Letters of credit subject to currency revaluation	$	47,954	$	68,435

Other Letters of credit, bank guarantees and surety bonds

We have posted surety bonds to support contractual obligations to customers relating to certain contracts. We utilize bonding facilities to support such obligations, but the issuance of bonds under those facilities is typically at the surety's discretion. These bonds generally indemnify customers should we fail to perform our obligations under our applicable contracts. We, and certain of our subsidiaries, have jointly executed general agreements of indemnity in favor of surety underwriters relating to surety bonds the underwriters issue in support of some of our contracting activity.

The following table provides a summary of outstanding letters of credit issued outside of the domestic facilities, and outstanding surety bonds:


	March 31,
	2024		2023





Letters of credit under non-domestic facilities	39,041		52,970






Surety Bonds	$	146,838	$	269,444

Our ability to obtain and maintain sufficient capacity under our current debt facilities is essential to allow us to support the issuance of letters of credit, bank guarantees and surety bonds. Without sufficient capacity, our ability to support contract security requirements in the future will be diminished.

NOTE 14 – CAPITAL STOCK

Preferred Stock

During the three months ending March 31, 2024, our Board of Directors approved dividends totaling $3.7 million to holders of the Preferred Stock. There were no cumulative undeclared dividends of the Preferred Stock at March 31, 2024, and all declared dividends have been paid as of April 1, 2024.

Common Stock

On April 10, 2024, we entered into a sales agreement (the “Sales Agreement”) with B. Riley Securities, Inc., Seaport Global Securities LLC, Craig-Hallum Capital Group LLC and Lake Street Capital Markets, LLC (together, the “Agents”), in connection with the offer and sale from time to time of shares of our common stock, having an aggregate offering price of up to $50.0 million through the Agents. As of May 3, 2024, 1.5 million shares have been sold pursuant to the Sales Agreement. Refer to Note 22 to the Condensed Consolidated Financial Statements for additional discussion of the Sales Agreement.

(1) We added $2.0 million in project indemnity restricted cash collateral for a letter of credit agreement during the first quarter of 2024.

(2) Beginning in January 2024, we drew $53.3 million on the Axos Credit Agreement for letter of credit collateral, which is reflected in Current and Long-term restricted cash in the Condensed Consolidated Balance Sheets.

(3) The purchase price for FPS was $59.2 million, and included an initial hold-back of $5.9 million which was included in Current restricted cash and cash equivalents and Other accrued liabilities in the Condensed Consolidated Balance Sheets. The final payment was made in the amount of $3.0 million during the first quarter of 2024.

(4) On December 15, 2021, we entered into an agreement to place $11.4 million in an escrow account as security to ensure project performance. The remaining amount of $0.3 million will be reclassified from Long-term restricted cash to Current restricted cash on September 30, 2024, with a scheduled final settlement on September 30, 2025.

NOTE 16 – PROVISION FOR INCOME TAXES

In the three months ended March 31, 2024, income tax expense from continuing operations was $1.3 million, resulting in an effective tax rate of (8.9)%. In the three months ended March 31, 2023, income tax expense from continuing operations was $0.5 million, resulting in an effective tax rate of (4.0)%.

The effective tax rate for the three months ended March 31, 2024 is not reflective of the U.S. statutory rate due to valuation allowances against certain net deferred tax assets and discrete items. We have unfavorable discrete items of $0.5 million and $0.2 million for the three months ended March 31, 2024 and 2023, respectively, which primarily represent withholding taxes.

We are subject to federal income tax in the United States and numerous countries that have statutory tax rates different than the United States federal statutory rate of 21%. The most significant of these foreign operations are located in Canada, Denmark, Germany, Italy, Mexico, Sweden, and the United Kingdom, with effective tax rates ranging between approximately 19% and 30%. We provide for income taxes based on the tax laws and rates in the jurisdictions where we have operations. These jurisdictions may have regimes of taxation that vary in both nominal rates and the basis on which these rates are applied. The consolidated effective income tax rate can vary from period to period due to these foreign income tax rate variations, changes in the jurisdictional mix of our income, and valuation allowances.

NOTE 17 – CONTINGENCIES

Litigation Relating to Boiler Installation and Supply Contract

On December 27, 2019, a complaint was filed against us by P.H. Glatfelter Company (“Glatfelter”) in the United States District Court for the Middle District of Pennsylvania, Case No. 1:19-cv-02215-JPW, alleging claims of breach of contract, fraud, negligent misrepresentation, promissory estoppel and unjust enrichment (the “Glatfelter Litigation”). The complaint alleges damages in excess of $58.9 million. On March 16, 2020 we filed a motion to dismiss, and on December 14, 2020 the court issued its order dismissing the fraud and negligent misrepresentation claims. On January 11, 2021, we filed an answer and a counterclaim for breach of contract, seeking damages in excess of $2.9 million. On November 30, 2022, we and

Glatfelter each filed cross-motions for summary judgment. On June 21, 2023, the court granted our motion in part, dismissing Glatfelter’s promissory estoppel and unjust enrichment claims, dismissing Babcock & Wilcox Enterprises, Inc. entirely (Glatfelter's remaining claim is asserted against The Babcock & Wilcox Company), and finding that Plaintiffs’ claims for damages will be subject to the contractual cap on liability (defined as the $11.7 million purchase price, subject to certain adjustments), and denied Glatfelter’s motion for summary judgment. The case is now set for trial on August 5, 2024. We intend to continue to vigorously litigate the action. However, given the uncertainty inherent in the litigation, it is too early to determine if the outcome of the Glatfelter Litigation will have a material adverse impact on our financial position, results of operations or cash flows.

Other

Due to the nature of our business, from time to time, we are involved in routine litigation or subject to disputes or claims related to our business activities, including, among other things: performance or warranty-related matters under our customer and supplier contracts and other business arrangements; and workers' compensation, premises liability and other claims. Based on prior experience, except as disclosed above, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

NOTE 18 – COMPREHENSIVE INCOME

Gains and losses deferred in accumulated other comprehensive income (loss) AOCI are generally reclassified and recognized in the Condensed Consolidated Statements of Operations once they are realized.

NOTE 19 – FAIR VALUE MEASUREMENTS

The following tables summarize financial assets and liabilities carried at fair value, all of which were valued from readily available prices or using inputs based upon quoted prices for similar instruments in active markets (known as "Level 1" and "Level 2" inputs, respectively, in the fair value hierarchy established by ASC 820, Fair Value Measurements and Disclosures).

Investments in available-for-sale securities are presented in Other assets in the Condensed Consolidated Balance Sheets with contractual maturities ranging from 0-5 years.

Senior Notes

See Note 13 to the Condensed Consolidated Financial Statements for a discussion of the senior notes. The fair value of the senior notes is based on readily available quoted market prices as of March 31, 2024:


(in thousands)	March 31, 2024
Senior Notes	Carrying Value		Estimated Fair Value
8.125% Senior Notes due 2026 ("BWSN")	$	193,035	$	126,245
6.50% Senior Notes due 2026 ("BWNB")	$	151,440	$	84,443

Other Financial Instruments

We used the following methods and assumptions in estimating fair value amounts for other financial instruments:

•Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts reported in the accompanying Condensed Consolidated Balance Sheets for cash and cash equivalents and restricted cash and cash equivalents approximate their fair value due to their highly liquid nature.

•Revolving Debt. We base the fair value of debt instruments on quoted market prices. Where quoted prices are not available, we base the fair value on Level 2 inputs such as the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms. The fair value of Revolving Debt approximated its carrying amount at March 31, 2024.

NOTE 20 – RELATED PARTY TRANSACTIONS

We believe transactions with related parties were conducted on terms equivalent to those prevailing in an arm's length transaction.

Transactions with B. Riley

Based on Schedule 13D filings with the SEC, B. Riley beneficially owns approximately 32.4% of our outstanding common stock as of March 31, 2024. B. Riley currently has the right to nominate one member of our Board of Directors pursuant to the investor rights agreement we entered into with B. Riley in April 2019. The investor rights agreement also provides pre-emptive rights to B. Riley with respect to certain future issuances of our equity securities.

As described further in Note 22, in April 2024, we entered into a sales agreement with B. Riley Securities, Inc., among others, in connection with the offer and sale from time to time of shares of our common stock. B. Riley will be entitled to compensation equal to 3.0% of the gross proceeds from each sale of the shares sold through it as the designated Agent.

As described in Note 13 to the Condensed Consolidated Financial Statements, in connection with our entry into the Axos Credit Agreement in January 2024, we entered into a guaranty agreement and a fee and reimbursement agreement with B. Riley. The B. Riley Guaranty provides for the guarantee of all of our obligations under the Credit Agreement. The B. Riley Guaranty is enforceable in certain circumstances, including, among others, certain events of default and the acceleration of our obligations under the Credit Agreement. The B. Riley Fee Agreement provides, among other things, for us to pay an annual fee to B. Riley equal to 2.00% of Aggregate Revolving Commitments under the Credit Agreement (or approximately $3 million) as consideration for B. Riley’s agreements and commitments under the B. Riley Guaranty. The B. Riley Fee Agreement also requires us to reimburse B. Riley to the extent the B. Riley Guaranty is called upon by the agent or lenders under the Credit Agreement and requires us to execute a junior secured promissory note with respect to the same within 60 days after the execution of the B. Riley Fee Agreement (or such other date as B. Riley may agree to).

We entered into an agreement with BRPI Executive Consulting, LLC, an affiliate of B. Riley, in November 2018 and amended the agreement in November 2020 and December 2023 to retain the services of Mr. Kenneth Young, to serve as our Chief Executive Officer until December 31, 2028, unless terminated by either party with thirty days written notice. Under this agreement, payments are $0.75 million per annum, paid monthly. Subject to the achievement of certain performance objectives as determined by the Compensation Committee of the Board of Directors, a bonus or bonuses may also be earned and payable to BRPI Executive Consulting, LLC.

NOTE 21 – NEW ACCOUNTING PRONOUNCEMENTS AND STANDARDS

New accounting standards to be adopted

We consider the applicability and impact of all issued ASUs. Certain recently issued ASUs were assessed and determined to be not applicable. New accounting standards not yet adopted that could affect the Condensed Consolidated Financial Statements in the future are summarized as follows:

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The new guidance is intended to align U.S. GAAP and SEC requirements while facilitating the application of U.S. GAAP for all entities. The effective date of ASU 2023-06 depends on (1) whether an entity is already subject to the SEC's current disclosure requirements and (2) whether and, if so, when the SEC removed related requirements from its regulations. For entities that are already subject to the SEC's current disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If the SEC has not removed the related requirements from its regulations by June 30, 2027, the amendments made by ASU 2023-06 will be removed from the Codification and will not become effective for any entity. We are currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items in interim and annual periods and expands the ASC 280 disclosure requirements for interim periods. The ASU also explicitly requires public entities with a single reportable segment to provide all segment disclosures under ASC 280, including the new disclosures under the ASU. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within

fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of specific categories in the effective tax rate reconciliation and additional information for reconciling items that meet a quantitative threshold. The standard is intended to benefit investors by providing more detailed income tax disclosures to assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Adoption of the standard will only impact the income tax disclosures and is not expected to be material to the Condensed Consolidated Financial Statements.

NOTE 22 – SUBSEQUENT EVENT

On April 10, 2024, we entered into a sales agreement (the "Sales Agreement") with B. Riley Securities, Inc., Seaport Global Securities LLC, Craig-Hallum Capital Group LLC and Lake Street Capital Markets, LLC (together, the "Agents"), in connection with the offer and sale from time to time of shares of our common stock, having an aggregate offering price of up to $50.0 million through the Agents. Any shares to be offered and sold under the Sales Agreement will be issued and sold pursuant to our previously filed and currently effective registration statement on Form S-3 initially filed with the SEC on November 8, 2021 and declared effective by the SEC on November 22, 2021. A prospectus supplement relating to the offering of the Shares was filed with the SEC on April 10, 2024.

The shares may be offered and sold through the Agents over a period of time and from time to time by any method that is deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended. The Agents are not required to sell any specific aggregate principal amount of our shares but will act as our sales agents using commercially reasonable efforts consistent with their normal trading and sales practices, on our mutually agreed terms with the Agents. Under the Sales Agreement, the designated Agent will be entitled to compensation equal to 3.0% of the gross proceeds from each sale of the shares sold through it as the designated Agent. The amount of net proceeds we will receive from this offering, if any, will depend upon the actual aggregate principal amount of the shares sold, after deduction of the Agents’ commission and any transaction fees. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and net proceeds to us, if any, are not determinable at this time.

The Sales Agreement contains customary representations, warranties and covenants of the Company, indemnification obligations of the Company and the Agents, including for liabilities under the Securities Act, other obligations of the parties and termination provisions.

Through May 3, 2024, we have sold 1.5 million shares pursuant to the Sales Agreement.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial position and results of operations should be read in conjunction with the financial statements and the notes thereto included in the Condensed Consolidated Financial Statements in Item 1 of this Quarterly Report. The following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements as a result of many factors, including those described in more detail under "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023. See also "Cautionary Statement Concerning Forward-Looking Information" herein. All amounts referred to in this discussion and analysis are on a continuing operations basis, unless otherwise noted.

BUSINESS OVERVIEW

We are a growing, globally-focused renewable, environmental and thermal technologies provider with over 155 years of experience providing diversified energy and emissions control solutions to a broad range of industrial, electrical utility, municipal and other customers. Our innovative products and services are organized into three market-facing segments. Our reportable segments are as follows:

•Babcock & Wilcox Renewable: Our innovative hydrogen generation technology (BrightLoopTM) supports global climate goals including the decarbonization of industrial and utility steam and power producers. BrightLoopTM offers significant advantages over other hydrogen generation technologies as it generates competitively priced hydrogen from a wide range of fuels (including solid fuels such as biomass and coal) with a high rate of carbon captured resulting in low (or even negative) carbon intensity hydrogen. We also offer best-in-class technologies for efficient and environmentally sustainable power and heat generation, including waste-to-energy, oxygen-fired biomass-to-energy (OxyBrightTM), and black liquor systems for the pulp and paper industry. Our leading waste-to-energy technologies support a circular economy, diverting waste from landfills to use for power generation or district heating, while recovering metals and reducing emissions. To date, we have installed approximately 500 waste-to-energy and biomass-to-energy units at more than 300 facilities in approximately 30 countries which serve a wide variety of utility, waste management, municipality and investment firm customers.

•Babcock & Wilcox Environmental: Our full suite of best-in-class emissions control and environmental technology solutions for utility, waste-to-energy, biomass-to-energy, carbon black, and industrial steam generation applications supports environmental stewardship around the world. Our broad experience includes systems for cooling, ash handling, particulate control, nitrogen oxide and sulfur dioxide removal, dioxin and furan control, carbon dioxide capture, mercury control as well as other acid gas and pollutant control. Our ClimateBrightTM family of products including SolveBrightTM, OxyBrightTM, BrightLoopTM and BrightGenTM, places us at the forefront of hydrogen production and carbon dioxide capturing technologies and development with many of the aforementioned products already commercially available and others ready for commercial deployment. We believe these technologies position us to compete in the bioenergy with carbon capture and sequestration market. Our portfolio of clean power production solutions continues to evolve to reach customers at all stages of their energy transition.

•Babcock & Wilcox Thermal: Our vast installed base of steam generation equipment and related auxiliaries spans the globe and includes customers in a variety of end markets including power generation, oil and gas, petrochemical, food and beverage, metals and mining, and others. We provide aftermarket parts, construction, maintenance, engineered upgrades and field services for our installed base as well as the installed base of other OEMs; the substantial and stable cash flows generated from these businesses helps to fund our investments in new clean energy initiatives. In addition to our aftermarket offerings, we also provide complete steam generation systems including package boilers, watertube and firetube waste heat boilers, and other boilers to medium and heavy industrial customers. Our unique range of offerings, coupled with the strength of our brand, provides a competitive advantage in existing and emerging markets.

Market Update

Management continues to adapt to macroeconomic conditions, including the impacts from inflation, higher interest rates and foreign exchange rate volatility, geopolitical conflicts (including the ongoing conflicts in Ukraine and the Middle East) and global shipping and supply chain disruptions that have continued to have an impact in 2024. In certain instances, these situations have resulted in cost increases and delays or disruptions that have had, and could continue to have, an adverse impact on our ability to meet customers’ demands. We continue to actively monitor the impact of these market conditions on

current and future periods and actively manage costs and our liquidity position to provide additional flexibility while still supporting our customers and their specific needs. The duration and scope of these conditions cannot be predicted, and therefore, any anticipated negative financial impact on our operating results cannot be reasonably estimated.

Discontinued Operations

We continued to meet the criteria to account for the B&W Solar business as held for sale and discontinued operations as of March 31, 2024.

RESULTS OF OPERATIONS

Components of Our Results of Operations

Revenue

Revenue is the total amount of income generated by our business and consists primarily of income from the renewable, environmental and thermal technology solutions and services we provide to a broad range of industrial, electric utility and other customers. Revenue from our operations is assessed based on our three market-facing segments, B&W Renewable, B&W Environmental and B&W Thermal.

Operating (loss) income

Operating (loss) income consists primarily of revenue minus costs and expenses, including cost of operations, SG&A, and advisory fees and settlement costs.

Net loss

Net loss consists primarily of operating (loss) income minus other income and expenses, including interest income, foreign exchange and expense related to our benefit plans, and provision for income taxes.

Consolidated Results of Operations

The following discussion of our consolidated and business segment results of operations includes a discussion of adjusted EBITDA, which, when used on a consolidated basis, is a non-GAAP financial measure. Adjusted EBITDA differs from net loss, the most directly comparable measure calculated in accordance with GAAP. Management believes that this financial measure is useful to investors because it excludes certain expenses, allowing investors to more easily compare our operating performance period to period. A reconciliation of net loss to adjusted EBITDA is included in “Non-GAAP Financial Measures” below.

Revenues:
B&W Renewable segment	$	52,281	$	84,123	$	(31,842)

	$	207,556	$	241,258	$	(33,702)

Three months ended March 31, 2024 and 2023

Revenues decreased by $33.7 million to $207.6 million in the three months ended March 31, 2024 as compared to $241.3 million in the three months ended March 31, 2023. The decrease was primarily driven by a $22.1 million decrease in B&W Renewable segment revenue because fewer waste-to-energy projects were performed in the current year as, consistent with our stated strategy, we shift our focus to our higher-margin and lower-risk European Renewable parts and services business and a $6.2 million decrease in B&W Thermal segment revenue as a large project in our U.S. construction business was completed in 2023 that was not fully replaced in 2024.

Operating income for the three months ended March 31, 2024 was $4.3 million as compared to $1.3 million in the three months ended March 31, 2023. The increase in 2024 was driven by a $6.6 million reduction in Selling, general and administrative costs primarily attributable to a favorable final settlement of a liability to the former owner of B&W Solar, and offset by $3.4 million lower gross margin due to the reduced revenue. Gross margin is defined as Revenues less Cost of Sales. Loss from continuing operations increased by $3.1 million to $15.8 million in the three months ended March 31, 2024 as compared to $12.7 million in the three months ended March 31, 2023. The increase was driven by a $5.1 million Loss on debt extinguishment as the remaining deferred financing fees associated with the terminated PNC Revolving Credit Agreement were written off.

Bookings and Backlog

Bookings and backlog are our measures of remaining performance obligations under our sales contracts. In addition, we monitor Implied Bookings and Backlog, which are bookings (backlog) plus amounts related to projects that have been awarded to us but are not fully under contract and/or projects under contract that are not yet fully released for performance. We believe these metrics provide investors, lenders and other users of our financial statements with a leading indicator of future revenues. It is possible that our methodology for determining bookings and backlog may not be comparable to methods used by other companies.

We generally include expected revenue from contracts in our backlog when we receive written confirmation from our customers authorizing the performance of work and committing the customers to payment for work performed. Backlog may not be indicative of future operating results, and contracts in our backlog may be canceled, modified or otherwise altered by customers. Backlog can vary significantly from period to period, particularly when large new-build conversion projects or operations and maintenance contracts are booked because they may be fulfilled over multiple years. Because we operate globally, our backlog is also affected by changes in foreign currencies each period.

Bookings represent changes to the backlog. Bookings include additions related to booking new business or increases in project scope, subtractions due to customer cancellations or reductions in scope, changes in estimates that affect selling price and revaluation of backlog denominated in foreign currency. We believe comparing bookings on a quarterly basis or for periods less than one year is less meaningful than for longer periods, and that shorter-term changes in bookings may not necessarily indicate a material trend.

Changes in Contract Estimates

During the three months ended March 31, 2024 and 2023, we recognized changes in estimated gross profit related to long-term contracts accounted for on the over time basis, which are summarized as follows:


	Three Months Ended March 31,
(in thousands)	2024		2023
Increases in gross profit for changes in estimates for over time contracts	$	6,964	$	5,401
Decreases in gross profit for changes in estimates for over time contracts	(3,891)		(4,243)
Net changes in gross profit for changes in estimates for over time contracts	$	3,073	$	1,158

Non-GAAP Financial Measures

We use non-GAAP financial measures internally to evaluate our performance and in making financial and operational decisions. When viewed in conjunction with GAAP results and the accompanying reconciliation, we believe that the presentation of these measures provides investors with greater transparency and a greater understanding of factors affecting our financial condition and results of operations than GAAP measures alone. The presentation of non-GAAP financial measures should not be considered in isolation or as a substitute for the related financial results prepared in accordance with GAAP.

The following discussion of our business segment results of operations includes a discussion of Adjusted EBITDA on a consolidated basis, which is a non-GAAP metric and differs from the most directly comparable GAAP measure. Adjusted EBITDA on a consolidated basis is defined as the sum of the adjusted EBITDA for each of the segments, further adjusted for corporate allocations and research and development costs. At a segment level, the adjusted EBITDA presented below is consistent with the way our chief operating decision maker reviews the results of operations and makes strategic decisions about the business and is calculated as earnings before interest, tax, depreciation and amortization adjusted for items such as gains or losses arising from the sale of non-income producing assets, net pension benefits, restructuring activities, impairments, gains and losses on debt extinguishment, costs related to financial consulting, research and development costs and other costs that may not be directly controllable by segment management and are not allocated to the segment. We present consolidated adjusted EBITDA because we believe it is useful to investors to facilitate comparisons of the ongoing, operating performance before corporate overhead and other expenses not attributable to the operating performance of our revenue-generating segments.

Corporate	(6,005)		(5,080)
Research and development costs	(116)		(1,307)
	$	12,535	$	13,574

Corporate

Corporate costs in adjusted EBITDA include SG&A expenses that are not allocated to the reportable segments. These costs include, among others, certain executive, compliance, strategic, reporting and legal expenses associated with governance of the organization and being an SEC registrant. Corporate expenses not allocated to the reportable segments totaled $6.0 million and $5.1 million in the three months ended March 31, 2024 and 2023, respectively. The increase is primarily due to the timing of expenses incurred for professional fees.

Research and development

Our research and development activities are focused on improving our products through innovations to reduce their cost and improve competitiveness and/or reduce performance risk of our products to better meet our and our customers’ expectations.

Research and development expenses totaled $0.1 million and $1.3 million in the three months ended March 31, 2024 and 2023, respectively. In 2024, the focus of our development activities shifted to our BrightLoopTM and ClimateBrightTM portfolio, which is captured in the Product development category.

Benefit plans, net

We recognize benefits from our defined benefit and other postretirement benefit plans based on actuarial calculations primarily because expected return on assets is greater than service cost. Service cost is low because our plan benefits are frozen except for a small number of hourly participants. Pension benefits for defined benefit and other postretirement benefits plans before MTM were a benefit of $0.1 million for the three months ended March 31, 2024 and expense of $0.1 million for the three months ended March 31, 2023, respectively.

Our pension costs include MTM adjustments and are primarily a result of changes in the discount rate, curtailments and settlements. Any MTM charge or gain should not be considered to be representative of future MTM adjustments as such events are not currently predicted and are in each case subject to market conditions and actuarial assumptions as of the date of the event giving rise to the MTM adjustment. There were no MTM adjustments for the three months ended March 31, 2024 or 2023.

Refer to Note 12 to the Condensed Consolidated Financial Statements for further information regarding our pension and other postretirement plans.

Loss on asset sales, net

We, at times, will sell or dispose of certain assets that are unrelated to our operations, therefore, we believe it is useful to exclude these gains and losses from our non-GAAP financial measures in order to highlight the performance of the business. We had $0.1 million and $0.9 million in losses on sales in the three months ended March 31, 2024 and 2023, respectively.

Stock Compensation

The grant date fair value of stock compensation varies based on the derived stock price at the time of grant, valuation methodologies, subjective assumptions, and reward types. This may make the impact of this form of compensation on our current financial results difficult to compare to previous and future periods. Therefore, we believe it is useful to exclude stock-based compensation from our non-GAAP financial measures in order to highlight the performance of the business and to be consistent with the way many investors evaluate our performance and compare our operating results to peer companies.

Expenses related to restricted stock units are recorded at the Corporate level and are recognized on a straight-line basis over a 3-year vesting period, except for market-based restricted stock units which are recognized over a derived service period.

Stock compensation was $1.4 million and $3.2 million for the three months ended March 31, 2024 and 2023, respectively.

Restructuring activities and business service transition costs

Restructuring activities and business services transition actions across our business units and corporate functions resulted in expense of $1.6 million and $1.0 million in the three months ended March 31, 2024 and 2023, respectively. The restructuring charges primarily consist of severance and related costs associated with non-recurring actions taken to transform our operations with impacts on employees and facilities used in our businesses. Business services transition costs relate to new technology implementation, expected to provide future benefit and are included in Selling, general and administrative expenses in the Condensed Consolidated Statement of Operations.

Settlements and related legal costs

Settlements and related legal costs were a benefit of $4.1 million and $2.5 million in the three months ended March 31, 2024 and 2023, respectively. The current year benefit is driven by the favorable final settlement of amounts owed to the former owner of B&W Solar, offset by expenses related to several smaller litigation matters. The benefit in the prior year was driven by a $2.5 million litigation settlement.

Product development

Our product development activities include expenses that relate to sales, marketing, and other business development expenses for products and services still under development and not yet widely available. Product development expenses totaled $1.6 million and $1.4 million in the three months ended March 31, 2024 and 2023, respectively. The increase resulted primarily from timing of specific research and increased development efforts and activities related to our BrightLoopTM commercialization efforts and to further develop our ClimateBrightTM portfolio. Management excludes these expenses from adjusted EBITDA as they often may not correlate to revenue or other operations occurring in the current period.

Foreign exchange

Foreign exchange was a loss of $1.3 million and $0.5 million for the three months ended March 31, 2024 and 2023, respectively.

We translate assets and liabilities of our foreign operations into U.S. dollars at current exchange rates, and we translate items in the statement of operations at average exchange rates for the periods presented. We record adjustments resulting from the translation of foreign currency financial statements as a component of accumulated other comprehensive income (loss). We report foreign currency transaction gains and losses in the Condensed Consolidated Statements of Operations.

Financial advisory services

We had financial advisory services of $0.2 million in the three months ended March 31, 2024. There were no financial advisory services in 2023.

Contract Disposal

We are in the process of exiting our only remaining fixed fee operational and maintenance ("O&M") contract in our Renewable segment. Losses related to this contract totaled $0.6 million and $1.4 million in the three months ended March 31, 2024 and 2023, respectively. We believe it is useful to exclude the impact of this contract on our operating results in order to highlight the performance of the ongoing business.

Letter of credit fees

Letter of credit fees included in Cost of operations were $2.4 million and $1.6 million for the three months ended March 31, 2024 and 2023, respectively. Letter of credit fees are routinely incurred in the course of executing customer contracts. A portion of the fees are included in the contract prices with our customers. These amounts represent performance guarantees akin to insurance that are not passed along to our customers and are excluded from adjusted EBITDA as they do not reflect the performance of the business.

Interest Expense

Interest expense in the Condensed Consolidated Financial Statements consisted of the following components:


	Three Months Ended March 31,

Income tax expense	$	1,293		$	490		$	803
Effective tax rate	(8.9)		%	(4.0)		%

Income tax expense in the first quarter of 2024 reflects a full valuation allowance against our net deferred tax assets, except in Mexico, Canada, the United Kingdom, Brazil, Finland, Germany, Thailand, the Philippines, Indonesia, and Sweden. Deferred tax assets are evaluated each period to determine whether realization is more likely than not. Valuation allowances are established when management determines it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. Valuation allowances may be removed in the future if sufficient positive evidence exists to outweigh the negative evidence under the framework of ASC 740, Income Taxes ASC 740.

The effective tax rate for the first quarter of 2024 is not reflective of the United States statutory rate primarily due to a valuation allowance against certain net deferred tax assets and unfavorable discrete items. In certain jurisdictions where we anticipate a loss for the fiscal year or incurs a loss for the year-to-date period for which a tax benefit cannot be realized in accordance with ASC 740, we exclude the loss in that jurisdiction from the overall computation of the estimated annual effective tax rate.

Depreciation and Amortization

Depreciation expense was $2.1 million and $2.9 million in the three months ended March 31, 2024 and 2023, respectively.

Amortization expense was $2.3 million and $2.4 million in the three months ended March 31, 2024 and 2023, respectively.

RESULTS BY SEGMENT

B&W Renewable Segment Results


	Three Months Ended March 31,
(in thousands)	2024		2023		$ Change
Revenues	$	52,281	$	84,123	$	(31,842)
Adjusted EBITDA	$	1,658	$	4,322	$	(2,664)

Three months ended March 31, 2024 and 2023

Revenues in the B&W Renewable segment decreased 38% or $31.8 million, to $52.3 million in the three months ended March 31, 2024 compared to $84.1 million in the three months ended March 31, 2023. Consistent with our stated strategy, fewer waste-to-energy projects were performed in the current year as we shift our focus to our higher-margin and lower-risk European Renewable parts and services business, leading to a decrease in revenue of $22.1 million.

Adjusted EBITDA in the B&W Renewable segment decreased $2.7 million, to $1.7 million in the three months ended March 31, 2024 compared to $4.3 million in the three months ended March 31, 2023 driven by a decrease of $3.6 million due to the reduced volume of waste-to-energy projects, partially offset by an increase of $1.1 million attributable to the European Renewable parts and services business.

B&W Environmental Segment Results


	Three Months Ended March 31,
(in thousands)	2024		2023		$ Change
Revenues	$	48,354	$	39,440	$	8,914
Adjusted EBITDA	$	3,326	$	1,906	$	1,420

Three months ended March 31, 2024 and 2023

Revenues in the B&W Environmental segment increased 23%, or $8.9 million to $48.4 million in the three months ended March 31, 2024 compared to $39.4 million in the three months ended March 31, 2023. The increase is primarily driven by higher revenue of $2.0 million in SPIG, our Air-Cooled Condenser business, and $2.1 million in our Allen-Sherman-Hoff ("ASH") ash handling business, as well as slightly increased volume in our parts business.

Adjusted EBITDA in the B&W Environmental segment was $3.3 million in the three months ended March 31, 2024 compared to $1.9 million in the three months ended March 31, 2023. The increase is primarily attributable to the higher revenue from SPIG and ASH projects and improved operating performance as certain environmental projects were completed in the quarter.

B&W Thermal Segment Results


	Three Months Ended March 31,
(In thousands)	2024		2023		$ Change
Revenues	$	110,187	$	119,236	$	(9,049)
Adjusted EBITDA	$	13,672	$	13,733	$	(61)

Three months ended March 31, 2024 and 2023

Revenues in the B&W Thermal segment decreased 8%, or $9.0 million to $110.2 million in the three months ended March 31, 2024 compared to $119.2 million in the three months ended March 31, 2023. A large project in our U.S. construction business was active in 2023 and was not fully replaced in 2024, resulting in decreased revenue of $6.2 million.

Adjusted EBITDA in the B&W Thermal segment was unchanged at $13.7 million in the three months ended March 31, 2024 and 2023, as an increase in international sales of $1.6 million was largely offset by the decreased Adjusted EBITDA in the U.S. construction business.

Liquidity and Capital Resources

Liquidity

Our primary liquidity requirements include debt service, funding of dividends on preferred stock and working capital needs. We fund our liquidity requirements primarily through cash generated from operations, external sources of financing, including our Axos Credit Agreement and senior notes, and equity offerings, including the Sales Agreement (as defined below) and our Preferred Stock, each of which are described in the Notes to Condensed Consolidated Financial Statements included in Part I, Item I of this Quarterly Report in further detail.

On April 10, 2024, we entered into a sales agreement (the "Sales Agreement") with B. Riley Securities, Inc., Seaport Global Securities LLC, Craig-Hallum Capital Group LLC and Lake Street Capital Markets, LLC (together, the "Agents"), in connection with the offer and sale from time to time of shares of our common stock, having an aggregate offering price of up to $50.0 million, through the Agents. As of May 3, 2024, 1.5 million shares have been sold pursuant to the Sales Agreement. Refer to Note 22 to the Condensed Consolidated Financial Statement for additional discussion of the Sales Agreement.

We have recurring operating losses primarily due to losses recognized on our B&W Solar business as described in Note 4 to the Consolidated Financial Statements included in Part II, Item 8 of our Form 10-K filed on March 15, 2024 as well as higher debt service costs. Our net cash used in operating activities was $14.9 million and $12.9 million for the three months ended March 31, 2024 and 2023, respectively. Our assessment of our ability to fund future operations is inherently subjective, judgment-based and susceptible to change based on future events. Currently, with existing cash on hand and available liquidity, we are projecting insufficient liquidity to fund operations through one year from the date this Quarterly Report is issued. These conditions and events raise substantial doubt about our ability to continue as a going concern.

In response to the conditions, we are implementing several strategies to obtain the required funding for future operations, and are considering other alternative measures to improve cash flow, including suspension of the dividend on our Preferred Stock. The following actions occurred during the three months ended March 31, 2024:

•initiated the sale process of certain of our non-strategic businesses;

•initiated the process to sell several non-core real estate assets;

•initiated the sale of common shares pursuant to our At-The-Market Offering; and,

•negotiated the settlement of a liability to the former owner of B&W Solar at a discount, resulting in future cash savings of $7.2 million..

Cash and Cash Flows

At March 31, 2024, cash and cash equivalents, current restricted cash and long-term restricted cash totaled $102.5 million, which included $58.6 million of restricted cash related to collateral for certain letters of credit. We had total debt of $441.6 million as well as $191.7 million of gross preferred stock outstanding. Our foreign business locations held $25.9 million of our total unrestricted cash and cash equivalents at March 31, 2024. In general, our foreign cash balances are not available to fund our U.S. operations unless the funds are repatriated or used to repay intercompany loans made from the U.S. to foreign entities, which could expose us to taxes we have not made a provision for in our results of operations. We presently have no plans to repatriate these funds to the U.S.

Cash used in operations was $14.9 million in the three months ended March 31, 2024, which is primarily attributable to the year-to-date net loss of $16.8 million. Cash used in operations was $12.9 million in the three months ended March 31, 2023, which was primarily attributed to the year-to-date net loss of $12.5 million.

Cash flows used in investing activities was $2.8 million and $2.2 million in the three months ended March 31, 2024 and 2023, respectively, primarily due to capital expenditures.

Cash flows provided by financing activities of $51.3 million in the three months ended March 31, 2024, primarily due to net borrowings on the Axos Credit Agreement of $61.6 million, offset by the payment of preferred dividend of $3.7 million. Cash flows used in financing activities was $5.9 million in the three months ended March 31, 2023, primarily due to the payment of the preferred stock dividend of $3.7 million and loan repayments of $1.7 million.

Debt Facilities

As discussed in Note 13 to the Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report, we entered into a new Credit Agreement with Axos in January 2024. B. Riley, a related party, has provided a guaranty of payment with regard to our obligations under the Credit Agreement. This agreement substantially replaces the existing Reimbursement Agreement, Revolving Credit Agreement and Letter of Credit Agreement. We are transitioning letters of credit outstanding under the Letter of Credit Agreement and Reimbursement Agreement to the Axos Credit Agreement. We believe all outstanding letters of credit will be transitioned to the Axos Credit Agreement by June 30, 2024, at which time the Letter of Credit Agreement and Reimbursement Agreement is expected to be terminated.

On April 30, 2024, we, along with certain subsidiaries as guarantors, the lenders party to the Credit Agreement , and Axos, as administrative agent, entered into the First Amendment to Credit Agreement (the “First Amendment”). The First Amendment, among other things, amends the terms of the Credit Agreement to increase the amounts available to be borrowed based on inventory in the borrowing base under the Credit Agreement (the "Increased Inventory Period"). In 2024, the Increased Inventory Period commences on April 30 and ends on July 31 and would provide approximately $6.0 million additional available borrowings under the Credit Agreement. The Increased Inventory Period is available to us upon our election in subsequent years (subject to a $75,000 fee if we make such an election), and commences on March 1 and ends on July 31.

At March 31, 2024, usage under the Credit Agreement and Letter of Credit Agreement consisted of $11.5 million of financial letters of credit and $68.1 million of performance letters of credit at March 31, 2024.

Letters of Credit, Bank Guarantees and Surety Bonds

Certain of our subsidiaries, that are primarily outside of the United States, have credit arrangements with various commercial banks and other financial institutions for the issuance of letters of credit and bank guarantees in association with contracting activity. The aggregate value of all such letters of credit and bank guarantees outside of our Letter of Credit Agreement as of March 31, 2024 was $39.0 million. The aggregate value of the outstanding letters of credit provided under the Letter of Credit Agreement backstopping letters of credit or bank guarantees was $17.2 million as of March 31, 2024. Of the outstanding letters of credit issued under the Letter of Credit Agreement, $48.0 million are subject to foreign currency revaluation.

Other Indebtedness - Loans Payable

As of March 31, 2024, we had loans payable of $103.2 million, net of debt issuance costs of $0.5 million, of which $4.5 million is classified as current, and $98.7 million as long-term loans payable on the Consolidated Balance Sheet. This includes $90.1 million on the revolving debt facilities, which is comprised of $36.8 million drawn on the revolving credit portion of the facility and $53.3 million drawn on the letter of credit portion, and $12.1 million, net of debt issuance costs of $0.5 million, related to sale-leaseback financing transactions.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

For a summary of the critical accounting policies and estimates that we use in the preparation of our unaudited Condensed Consolidated Financial Statements, see "Critical Accounting Policies and Estimates" in the Annual Report on Form 10-K for the year ended December 31, 2023. There have been no significant changes to our policies during the three months ended March 31, 2024 from those disclosed in the Annual Report on Form 10-K for the year ended December 31, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risks has not changed materially from those disclosed under "Quantitative and Qualitative Disclosures About Market Risk" in the Annual Report on Form 10-K for the year ended December 31, 2023.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of the end of the period covered by this report, our management, with the participation of our Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the Securities and Exchange Commission under the Securities Exchange Act, as amended (the "Exchange Act")).

Based on this evaluation and because of the previously-reported material weaknesses in internal control over financial reporting, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2024.

Notwithstanding the conclusion by our Chief Executive Officer and Chief Financial Officer that our disclosure controls and procedures as of March 31, 2024 were not effective, our management, including our Chief Executive Officer and Chief Financial Officer, has concluded that the Condensed Consolidated Financial Statements as of and for the three months ended March 31, 2024 and 2023 present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

Remediation Plan and Status

As of March 31, 2024, the material weaknesses previously disclosed have not yet been remediated. In response to the material weaknesses in our internal control over financial reporting, management has initiated remediation efforts, which includes:

•continuing to hire qualified accounting professionals;

•developing and providing additional training to the accounting and financial reporting team;

•designing and implementing additional and/or enhanced controls in the areas of account reconciliations, contract accounting, financial statement analysis and complex and/or non-routine transactions;

•enhancing controls over IT user access and segregation of duties; and,

•developing and implementing a monitoring program to evaluate and assess whether controls are present and functioning appropriately.

We will continue to work towards full remediation of the material weaknesses to improve our internal control over financial reporting. The material weaknesses will not be considered remediated until the new and redesigned controls operate for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively. Accordingly, we will continue to monitor and evaluate the effectiveness of our internal control over financial reporting in the areas affected by the material weaknesses.

Changes in Internal Control Over Financial Reporting

There were no changes in internal control over financial reporting (as defined by Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations in Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures, or our internal controls, will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake or fraud. Additionally, controls can be circumvented by individuals or groups of persons or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements in our public reports due to error or fraud may occur and not be detected.

PART II

Item 1. Legal Proceedings

For information regarding ongoing investigations and litigation, see Note 17 to the Condensed Consolidated Financial Statements included in Part I, Item I of this Quarterly Report, which we incorporate by reference into this Item.

Item 1A. Risk Factors

We are subject to various risks and uncertainties in the course of our business. The discussion of such risks and uncertainties may be found under “Risk Factors” in the Annual Report on Form 10-K for the fiscal year ended December 31, 2023. There have been no material changes to the risk factors set forth in the Annual Report on Form 10-K for the year ended December 31, 2023.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

In accordance with the provisions of the employee benefit plans, we acquire shares in connection with the vesting of employee restricted stock that require us to withhold shares to satisfy employee statutory income tax withholding obligations. During the quarter ended March 31, 2024, we did not have any repurchases of shares related to employee restricted stock plans. Also, we do not have a general share repurchase program at this time.

EXECUTION COPY FIRST AMENDMENT TO CREDIT AGREEMENT This First Amendment to Credit Agreement (this “Amendment”) is made as of April 30, 2024, by and among: BABCOCK & WILCOX ENTERPRISES, INC., a Delaware corporation (the “ Borrower”); the Persons named on Schedule I hereto (individually, a “Guarantor”, and collectively, the “Guarantors”, and together with the Borrower, individually, a “Loan Party”, and collectively, the “Loan Parties”); the LENDERS party hereto; and AXOS BANK, as Administrative Agent; in consideration of the mutual covenants herein contained and benefits to be derived herefrom. W I T N E S S E T H: WHEREAS, reference is made to that certain Credit Agreement, dated as of January 18, 2024 (as amended, modified, extended, restated, renewed, replaced, or supplemented from time to time, the “Credit Agreement”), by, among others, the Loan Parties, the Lenders party thereto from time to time, and Axos Bank, as Administrative Agent; and WHEREAS, the parties hereto have agreed to amend certain provisions of the Credit Agreement as set forth herein. NOW, THEREFORE, in consideration of the mutual conditions and agreements set forth in this Amendment, and for good and valuable consideration, the receipt of which is hereby acknowledged, the undersigned hereby agree as hereinafter provided: 1. Defined Terms. Capitalized terms used in this Amendment shall have the respective meanings assigned to such terms in the Credit Agreement unless otherwise defined herein. 2. Amendments to Credit Agreement. The Credit Agreement is hereby amended as follows: (a) Section 1.01 of the Credit Agreement is hereby amended as follows: (i) By amending the definition of “Borrowing Base” by amending and restating clause (a) thereof to read in its entirety as follows: “ “(a) the least of (i) $25,000,000, (ii) 55% multiplied by the face amount of Eligible Trade Receivables, (iii) Cost of Eligible Inventory, multiplied by the NOLV Percentage, or (iv) the Cost of Eligible Inventory, multiplied by the Inventory Advance Rate; plus” (ii) By amending and restating the definition of “Early Termination Fee” to read in its entirety as follows: “ “Early Termination Fee” has the meaning specified in the Fee Letter described in clause (i) of the definition of such term.”

2 (iii) By amending and restating the definition of “Fee Letter” to read in its entirety as follows: “ “Fee Letter” means, collectively, (i) the letter agreement, dated as of the Closing Date, between the Borrower and the Administrative Agent, and (ii) the letter agreement, dated as of the First Amendment Effective Date, between the Borrower and the Administrative Agent.” (iv) By adding the following new definitions thereto in appropriate alphabetical order: “ “Increased Inventory Period” means the period between March 1 and July 31 of each calendar year (other than with respect to the calendar year 2024, in which case the period between the First Amendment Effective Date and July 31, 2024), to the extent elected by the Borrower for each applicable calendar year in a written notice to the Administrative Agent by February 1 of such calendar year; provided, further, that notwithstanding the foregoing, the Increased Inventory Period for the calendar year 2024 shall be the period commencing on the First Amendment Effective Date and ending on July 31, 2024. For the avoidance of doubt, except as provided in the second proviso in the immediately preceding sentence, (x) the Borrower may not elect to utilize an Increased Inventory Period for any calendar year that is shorter than the period between March 1 and July 31 of such calendar year, and (y) if the Administrative Agent has not received a written notice of election to utilize an Increased Inventory Period for any calendar year by February 1 of such calendar year, the Borrower shall be deemed to have declined its right to make any such election for such calendar year.” “ “NOLV Percentage” means, as of any date of determination, (i) at all times other than during an Increased Inventory Period, the product of the Appraisal Percentage multiplied by the Appraised Value of Eligible Inventory, and (ii) during an Increased Inventory Period, the greater of (x) the product of the Appraisal Percentage multiplied by the Appraised Value of Eligible Inventory, and (y) (1) during the period between March 1 and June 30 of such Increased Inventory Period, 30%, or (2) during the period between July 1 and July 31 of such Increased Inventory Period, 25%.” 3. Ratification of Loan Documents.

3 previously pledged to the Administrative Agent, for the benefit of the Secured Parties, pursuant thereto, shall continue to secure all applicable Obligations of the Loan Parties at any time and from time to time outstanding under the Credit Agreement and the other Loan Documents. 4.

(c) This Amendment, the Credit Agreement, the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent or the L/C Issuer, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Amendment shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. (d) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A

Unless otherwise defined herein, capitalized terms shall have the meanings set forth in the Credit Agreement or the First Amendment, as applicable. The Borrower has requested, and the Administrative Agent and the Lenders have agreed, to amend the Credit Agreement to, among other things, increase amounts available to be borrowed based on Inventory in the Borrowing Base. In connection with, and in consideration of, such amendments to the Credit Agreement, the Borrower hereby agrees as follows (this letter agreement being hereinafter referred to as this “First Amendment Fee Letter”): 1. Amendment Fee. The Borrower shall pay to the Administrative Agent, for the ratable benefit of the Revolving Lenders, an amendment fee (the “Amendment Fee”) in the amount of $75,000. The Amendment Fee shall be earned by, and payable in full by the Borrower to, the Administrative Agent on the First Amendment Effective Date. 2. Increased Inventory Fee. For each calendar year in which the Borrower elects to utilize an Increased Inventory Period, the Borrower shall pay to the Administrative Agent, for the account of each Revolving Lender in accordance with its Applicable Revolving Percentage, an increased inventory fee (the “Increased Inventory Fee”) equal to $75,000. Each Increased Inventory Fee shall be fully earned on March 1 of the calendar year for which such an election is made and shall be payable in full on the earliest to occur of (i) April 30 of such year, (ii) the occurrence of an Event of Default following March 1 of such year, and (iii) the last day of the Availability Period for the Revolving Facility. 3. General. All fees payable under this First Amendment Fee Letter constitute compensation for services rendered and do not constitute interest or a charge for the use of money. All fees payable hereunder shall be fully earned when due and shall not be subject to refund or rebate under any circumstances. All fees payable hereunder will be paid in immediately available funds and shall not be subject to reduction by way of setoff or counterclaim or otherwise affected under any

2 circumstance. All fees received by the Administrative Agent hereunder may be shared the Administrative Agent and its Affiliates as the Administrative Agent may determine in its sole discretion. Each of the foregoing fees shall be payable in Dollars in immediately available funds, free and clear of and without deduction for any and all present or future applicable taxes, levies, imposts, deductions, charges or withholdings and all liabilities with respect thereto and shall be in addition to any other fees, costs or expenses which may be due to the Administrative Agent and/or the Lenders pursuant to the terms of the Credit Agreement. You agree not to disclose any or all of the terms of this First Amendment Fee Letter to any Person other than (a) to your employees, attorneys, direct and indirect investors, consultants, or accountants, in each case, to whom it is necessary or advisable to disclose the information, and then only on a confidential basis in connection with the transactions contemplated hereby (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of the terms of this First Amendment Fee Letter and instructed to keep such terms confidential), and (b) as may be required by law or any court or regulatory agency having jurisdiction over you or any of your direct or indirect beneficial owners (in which case you agree to inform the Administrative Agent promptly thereof).

Each of the Loan Parties and each of the Administrative Agent and each Lender Party agrees that any Electronic Signature on or associated with this First Amendment Fee Letter shall be valid and binding on such Person to the same extent as a manual, original signature, and that any First Amendment Fee Letter entered into by Electronic Signature, will constitute the legal, valid and binding obligation of such Person enforceable against such Person in accordance with the terms thereof to the same extent as if a manually executed original signature was delivered. This First Amendment Fee Letter may be executed in as many counterparts as necessary or convenient, including both paper and electronic counterparts, but all such counterparts are one and the same instrument.

Notwithstanding anything contained herein to the contrary, the Administrative Agent is not under any

3 obligation to accept an Electronic Signature in any form or in any format unless expressly agreed to by the Administrative Agent pursuant to procedures approved by it; provided, further, without limiting the foregoing, (a) to the extent the Administrative Agent has agreed to accept such Electronic Signature, the Administrative Agent shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of any Loan Party without further verification and (b) upon the request of the Administrative Agent, any Electronic Signature shall be promptly followed by such manually executed counterpart.

The provisions of this First Amendment Fee Letter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent. Nothing in this First Amendment Fee Letter, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in Section 11.06(d) of the Credit Agreement and, to the extent expressly contemplated thereby, the Related Parties of each of the Administrative Agent, the L/C Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this First Amendment Fee Letter.

Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION These interim Condensed Consolidated Financial Statements of Babcock & Wilcox Enterprises, Inc. (“B&W,” “management,” “we,” “us,” “our” or the “Company”) have been prepared in accordance with GAAP and SEC instructions for interim financial information, and should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2023. The Notes to Condensed Consolidated Financial Statements are presented on the basis of continuing operations, unless otherwise stated. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these Condensed Consolidated Financial Statements contain all estimates and adjustments, consisting of normal recurring adjustments, required to fairly present the financial position, results of operations, and cash flows for the periods presented. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2024. There have been no material changes to our significant accounting policies included in the Annual Report on Form 10-K for the year ended December 31, 2023. Non-controlling interests are presented in the Condensed Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (non-controlling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in non-controlling interests are reported as equity in the Condensed Consolidated Financial Statements. Additionally, the Condensed Consolidated Financial Statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and non-controlling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Liquidity and Going Concern The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. We have recurring operating losses primarily due to losses recognized on our B&W Solar business as described in Note 4 to the Consolidated Financial Statements included in Part II, Item 8 of our Form 10-K filed on March 15, 2024 as well as higher debt service costs. Our assessment of our ability to fund future operations is inherently subjective, judgment-based and susceptible to change based on future events. Currently, with existing cash on hand and available liquidity, we are projecting insufficient liquidity to fund operations through one year following the date that this Quarterly Report is issued. These conditions and events raise substantial doubt about our ability to continue as a going concern. In response to the conditions, we are implementing several strategies to obtain the required funding for future operations and are considering other alternative measures to improve cash flow, including suspension of the dividend on our Preferred Stock. The following actions occurred during the three months ended March 31, 2024: •entered into advanced negotiations related to the sale of one of our non-strategic businesses. Proceeds from the sale are expected to be approximately $40.0 million to $46.0 million, subject to due diligence and continuing negotiations. We cannot provide any assurances that such transaction will close or that proceeds will not be more or less than we anticipate; •initiated the process to sell certain of our other non-strategic businesses; •filed for a waiver of required minimum contributions to the Retirement Plan for Employees of Babcock & Wilcox Commercial Operations (the "U.S. Plan"), that if granted, would reduce cash funding requirements in 2024 and would increase contributions annually over the subsequent five-year period. We cannot provide any assurances that such waiver will be granted; •initiated the process to sell several non-core real estate assets; •initiated the sale of common shares pursuant to our At-The-Market Offering; and •negotiated the settlement of a liability to the former owner of B&W Solar at a discount, resulting in future cash savings of $7.2 million. Based on our ability to raise funds through the actions noted above and our Cash and cash equivalents as of March 31, 2024, we have concluded it is probable that such actions would provide sufficient liquidity to fund operations for the next twelve months following the date of this Quarterly Report. As a result, it is probable that our cash flow improvement plans and anticipated proceeds from the sale of non-strategic assets alleviate the substantial doubt about our ability to continue as a going concern. Operations Our operations are assessed based on three reportable market-facing segments consistent with our strategic initiative to accelerate growth and provide stakeholders improved visibility into our renewable and environmental growth platforms. Our reportable segments are as follows: •Babcock & Wilcox Renewable: Technologies for efficient and environmentally sustainable power and heat generation, including waste-to-energy, biomass-to-energy and black liquor systems for the pulp and paper industry. Our technologies support a circular economy, diverting waste from landfills to use for power generation and replacing fossil fuels, while recovering metals and reducing emissions. •Babcock & Wilcox Environmental: A full suite of emissions control and environmental technology solutions for utility, waste-to-energy, biomass-to-energy, carbon black, and industrial steam generation applications around the world. Our broad experience includes systems for cooling, ash handling, particulate control, nitrogen oxides and sulfur dioxides removal, chemical looping for carbon control, and mercury control. •Babcock & Wilcox Thermal: Steam generation equipment, aftermarket parts, construction, maintenance and field services for plants in the power generation, oil and gas, and industrial sectors. We have an extensive global base of installed equipment for utilities and general industrial applications including refining, petrochemical, food processing, metals and others. For financial information about our segments see Note 4 to the Condensed Consolidated Financial Statements.

PROVISION FOR INCOME TAXES	Mar. 31, 2024
Income Tax Disclosure [Abstract]
PROVISION FOR INCOME TAXES	PROVISION FOR INCOME TAXES In the three months ended March 31, 2024, income tax expense from continuing operations was $1.3 million, resulting in an effective tax rate of (8.9)%. In the three months ended March 31, 2023, income tax expense from continuing operations was $0.5 million, resulting in an effective tax rate of (4.0)%. The effective tax rate for the three months ended March 31, 2024 is not reflective of the U.S. statutory rate due to valuation allowances against certain net deferred tax assets and discrete items. We have unfavorable discrete items of $0.5 million and $0.2 million for the three months ended March 31, 2024 and 2023, respectively, which primarily represent withholding taxes. We are subject to federal income tax in the United States and numerous countries that have statutory tax rates different than the United States federal statutory rate of 21%. The most significant of these foreign operations are located in Canada, Denmark, Germany, Italy, Mexico, Sweden, and the United Kingdom, with effective tax rates ranging between approximately 19% and 30%. We provide for income taxes based on the tax laws and rates in the jurisdictions where we have operations. These jurisdictions may have regimes of taxation that vary in both nominal rates and the basis on which these rates are applied. The consolidated effective income tax rate can vary from period to period due to these foreign income tax rate variations, changes in the jurisdictional mix of our income, and valuation allowances.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES Litigation Relating to Boiler Installation and Supply Contract On December 27, 2019, a complaint was filed against us by P.H. Glatfelter Company (“Glatfelter”) in the United States District Court for the Middle District of Pennsylvania, Case No. 1:19-cv-02215-JPW, alleging claims of breach of contract, fraud, negligent misrepresentation, promissory estoppel and unjust enrichment (the “Glatfelter Litigation”). The complaint alleges damages in excess of $58.9 million. On March 16, 2020 we filed a motion to dismiss, and on December 14, 2020 the court issued its order dismissing the fraud and negligent misrepresentation claims. On January 11, 2021, we filed an answer and a counterclaim for breach of contract, seeking damages in excess of $2.9 million. On November 30, 2022, we and Glatfelter each filed cross-motions for summary judgment. On June 21, 2023, the court granted our motion in part, dismissing Glatfelter’s promissory estoppel and unjust enrichment claims, dismissing Babcock & Wilcox Enterprises, Inc. entirely (Glatfelter's remaining claim is asserted against The Babcock & Wilcox Company), and finding that Plaintiffs’ claims for damages will be subject to the contractual cap on liability (defined as the $11.7 million purchase price, subject to certain adjustments), and denied Glatfelter’s motion for summary judgment. The case is now set for trial on August 5, 2024. We intend to continue to vigorously litigate the action. However, given the uncertainty inherent in the litigation, it is too early to determine if the outcome of the Glatfelter Litigation will have a material adverse impact on our financial position, results of operations or cash flows. Other Due to the nature of our business, from time to time, we are involved in routine litigation or subject to disputes or claims related to our business activities, including, among other things: performance or warranty-related matters under our customer and supplier contracts and other business arrangements; and workers' compensation, premises liability and other claims. Based on prior experience, except as disclosed above, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS We believe transactions with related parties were conducted on terms equivalent to those prevailing in an arm's length transaction. Transactions with B. Riley Based on Schedule 13D filings with the SEC, B. Riley beneficially owns approximately 32.4% of our outstanding common stock as of March 31, 2024. B. Riley currently has the right to nominate one member of our Board of Directors pursuant to the investor rights agreement we entered into with B. Riley in April 2019. The investor rights agreement also provides pre-emptive rights to B. Riley with respect to certain future issuances of our equity securities. As described further in Note 22, in April 2024, we entered into a sales agreement with B. Riley Securities, Inc., among others, in connection with the offer and sale from time to time of shares of our common stock. B. Riley will be entitled to compensation equal to 3.0% of the gross proceeds from each sale of the shares sold through it as the designated Agent. As described in Note 13 to the Condensed Consolidated Financial Statements, in connection with our entry into the Axos Credit Agreement in January 2024, we entered into a guaranty agreement and a fee and reimbursement agreement with B. Riley. The B. Riley Guaranty provides for the guarantee of all of our obligations under the Credit Agreement. The B. Riley Guaranty is enforceable in certain circumstances, including, among others, certain events of default and the acceleration of our obligations under the Credit Agreement. The B. Riley Fee Agreement provides, among other things, for us to pay an annual fee to B. Riley equal to 2.00% of Aggregate Revolving Commitments under the Credit Agreement (or approximately $3 million) as consideration for B. Riley’s agreements and commitments under the B. Riley Guaranty. The B. Riley Fee Agreement also requires us to reimburse B. Riley to the extent the B. Riley Guaranty is called upon by the agent or lenders under the Credit Agreement and requires us to execute a junior secured promissory note with respect to the same within 60 days after the execution of the B. Riley Fee Agreement (or such other date as B. Riley may agree to). We entered into an agreement with BRPI Executive Consulting, LLC, an affiliate of B. Riley, in November 2018 and amended the agreement in November 2020 and December 2023 to retain the services of Mr. Kenneth Young, to serve as our Chief Executive Officer until December 31, 2028, unless terminated by either party with thirty days written notice. Under this agreement, payments are $0.75 million per annum, paid monthly. Subject to the achievement of certain performance objectives as determined by the Compensation Committee of the Board of Directors, a bonus or bonuses may also be earned and payable to BRPI Executive Consulting, LLC.

NEW ACCOUNTING PRONOUNCEMENTS AND STANDARDS	Mar. 31, 2024
Accounting Policies [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS AND STANDARDS	NEW ACCOUNTING PRONOUNCEMENTS AND STANDARDS New accounting standards to be adopted We consider the applicability and impact of all issued ASUs. Certain recently issued ASUs were assessed and determined to be not applicable. New accounting standards not yet adopted that could affect the Condensed Consolidated Financial Statements in the future are summarized as follows: In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The new guidance is intended to align U.S. GAAP and SEC requirements while facilitating the application of U.S. GAAP for all entities. The effective date of ASU 2023-06 depends on (1) whether an entity is already subject to the SEC's current disclosure requirements and (2) whether and, if so, when the SEC removed related requirements from its regulations. For entities that are already subject to the SEC's current disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If the SEC has not removed the related requirements from its regulations by June 30, 2027, the amendments made by ASU 2023-06 will be removed from the Codification and will not become effective for any entity. We are currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items in interim and annual periods and expands the ASC 280 disclosure requirements for interim periods. The ASU also explicitly requires public entities with a single reportable segment to provide all segment disclosures under ASC 280, including the new disclosures under the ASU. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of specific categories in the effective tax rate reconciliation and additional information for reconciling items that meet a quantitative threshold. The standard is intended to benefit investors by providing more detailed income tax disclosures to assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Adoption of the standard will only impact the income tax disclosures and is not expected to be material to the Condensed Consolidated Financial Statements.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENT On April 10, 2024, we entered into a sales agreement (the "Sales Agreement") with B. Riley Securities, Inc., Seaport Global Securities LLC, Craig-Hallum Capital Group LLC and Lake Street Capital Markets, LLC (together, the "Agents"), in connection with the offer and sale from time to time of shares of our common stock, having an aggregate offering price of up to $50.0 million through the Agents. Any shares to be offered and sold under the Sales Agreement will be issued and sold pursuant to our previously filed and currently effective registration statement on Form S-3 initially filed with the SEC on November 8, 2021 and declared effective by the SEC on November 22, 2021. A prospectus supplement relating to the offering of the Shares was filed with the SEC on April 10, 2024. The shares may be offered and sold through the Agents over a period of time and from time to time by any method that is deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended. The Agents are not required to sell any specific aggregate principal amount of our shares but will act as our sales agents using commercially reasonable efforts consistent with their normal trading and sales practices, on our mutually agreed terms with the Agents. Under the Sales Agreement, the designated Agent will be entitled to compensation equal to 3.0% of the gross proceeds from each sale of the shares sold through it as the designated Agent. The amount of net proceeds we will receive from this offering, if any, will depend upon the actual aggregate principal amount of the shares sold, after deduction of the Agents’ commission and any transaction fees. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and net proceeds to us, if any, are not determinable at this time. The Sales Agreement contains customary representations, warranties and covenants of the Company, indemnification obligations of the Company and the Agents, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. Through May 3, 2024, we have sold 1.5 million shares pursuant to the Sales Agreement.

BASIS OF PRESENTATION (Policies)	3 Months Ended
BASIS OF PRESENTATION (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Liquidity and Going Concern	Liquidity and Going Concern The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. We have recurring operating losses primarily due to losses recognized on our B&W Solar business as described in Note 4 to the Consolidated Financial Statements included in Part II, Item 8 of our Form 10-K filed on March 15, 2024 as well as higher debt service costs. Our assessment of our ability to fund future operations is inherently subjective, judgment-based and susceptible to change based on future events. Currently, with existing cash on hand and available liquidity, we are projecting insufficient liquidity to fund operations through one year following the date that this Quarterly Report is issued. These conditions and events raise substantial doubt about our ability to continue as a going concern. In response to the conditions, we are implementing several strategies to obtain the required funding for future operations and are considering other alternative measures to improve cash flow, including suspension of the dividend on our Preferred Stock. The following actions occurred during the three months ended March 31, 2024: •entered into advanced negotiations related to the sale of one of our non-strategic businesses. Proceeds from the sale are expected to be approximately $40.0 million to $46.0 million, subject to due diligence and continuing negotiations. We cannot provide any assurances that such transaction will close or that proceeds will not be more or less than we anticipate; •initiated the process to sell certain of our other non-strategic businesses; •filed for a waiver of required minimum contributions to the Retirement Plan for Employees of Babcock & Wilcox Commercial Operations (the "U.S. Plan"), that if granted, would reduce cash funding requirements in 2024 and would increase contributions annually over the subsequent five-year period. We cannot provide any assurances that such waiver will be granted; •initiated the process to sell several non-core real estate assets; •initiated the sale of common shares pursuant to our At-The-Market Offering; and •negotiated the settlement of a liability to the former owner of B&W Solar at a discount, resulting in future cash savings of $7.2 million. Based on our ability to raise funds through the actions noted above and our Cash and cash equivalents as of March 31, 2024, we have concluded it is probable that such actions would provide sufficient liquidity to fund operations for the next twelve months following the date of this Quarterly Report. As a result, it is probable that our cash flow improvement plans and anticipated proceeds from the sale of non-strategic assets alleviate the substantial doubt about our ability to continue as a going concern.
Operations	Operations Our operations are assessed based on three reportable market-facing segments consistent with our strategic initiative to accelerate growth and provide stakeholders improved visibility into our renewable and environmental growth platforms. Our reportable segments are as follows: •Babcock & Wilcox Renewable: Technologies for efficient and environmentally sustainable power and heat generation, including waste-to-energy, biomass-to-energy and black liquor systems for the pulp and paper industry. Our technologies support a circular economy, diverting waste from landfills to use for power generation and replacing fossil fuels, while recovering metals and reducing emissions. •Babcock & Wilcox Environmental: A full suite of emissions control and environmental technology solutions for utility, waste-to-energy, biomass-to-energy, carbon black, and industrial steam generation applications around the world. Our broad experience includes systems for cooling, ash handling, particulate control, nitrogen oxides and sulfur dioxides removal, chemical looping for carbon control, and mercury control. •Babcock & Wilcox Thermal: Steam generation equipment, aftermarket parts, construction, maintenance and field services for plants in the power generation, oil and gas, and industrial sectors. We have an extensive global base of installed equipment for utilities and general industrial applications including refining, petrochemical, food processing, metals and others. For financial information about our segments see Note 4 to the Condensed Consolidated Financial Statements.
New accounting standards to be adopted	New accounting standards to be adopted We consider the applicability and impact of all issued ASUs.

For entities that are already subject to the SEC's current disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If the SEC has not removed the related requirements from its regulations by June 30, 2027, the amendments made by ASU 2023-06 will be removed from the Codification and will not become effective for any entity. We are currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items in interim and annual periods and expands the ASC 280 disclosure requirements for interim periods.
