QUEST RESOURCE HOLDING CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. The Company and Description of Business

The accompanying condensed consolidated financial statements include the accounts of Quest Resource Holding Corporation (“QRHC”) and its subsidiaries, Quest Resource Management Group, LLC (“Quest”), Landfill Diversion Innovations, LLC (“LDI”), Youchange, Inc. (“Youchange”), Quest Vertigent Corporation (“QVC”), Quest Vertigent One, LLC (“QV One”), and Quest Sustainability Services, Inc. (“QSS”) (collectively, “we”, “us”, or “our company”).

Operations – We are a national provider of waste and recycling services to customers from across multiple industry sectors that are typically larger, multi-location businesses. We create customer-specific programs and perform the related services for the collection, processing, recycling, disposal, and tracking of waste streams and recyclables. In addition, we offer products such as antifreeze and windshield washer fluid and other minor ancillary services. We also provide information and data that tracks and reports the detailed transactional and environmental results of our services and provides actionable data to improve business operations. The data we generate also enables our customers to address their environmental and sustainability goals and responsibilities.

2. Summary of Significant Accounting Policies

Principles of Presentation and Consolidation

The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2023. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading.

The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at March 31, 2024 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2023 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary.

All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires incremental disclosures related to reportable segments, including significant segment expense categories and amounts for each reportable segment. Entities with a single reportable segment are required to provide the new disclosures required under Accounting Standards Codification (“ASC”) 280. This authoritative guidance is required to be applied retrospectively and will be effective for our annual disclosures beginning in 2024 and interim periods starting 2025. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires entities to provide additional disclosure related to the transparency and decision usefulness of income tax disclosures, including additional disclosure around the rate reconciliation and income taxes paid. The authoritative guidance should be applied prospectively and will be effective for us starting in 2025. Retrospective application is permitted. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.

3. Accounts Receivable, Net of Allowance for Doubtful Accounts

Our receivables, which are recorded when billed or when services are performed, are claims against third parties that will generally be settled in cash. The carrying value of our receivables, net of the allowance for doubtful accounts, represents the estimated net realizable value. We estimate our allowance for doubtful accounts based on consideration of a number of factors, including the length of time trade accounts are past due, our previous loss history, the creditworthiness of individual customers, economic conditions

6

affecting specific customer industries, and economic conditions in general. We write off past-due receivable balances after all reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to bad debt expense in the period we receive the payment.

The following table reflects the activity in our allowance for doubtful accounts of trade receivables for the three months ended March 31, 2024 and 2023:

	Three Months Ended March 31,
	2024			2023
	(Unaudited)
Beginning balance	$	1,581,595		$	2,176,010
Bad debt expense		568,675			243,909
Uncollectible accounts written off, net of recoveries		(192,208	)		(145,379	)
Ending balance	$	1,958,062		$	2,274,540

4. Property and Equipment, Net, and Other Assets

At March 31, 2024 and December 31, 2023, property and equipment, net, and other assets consisted of the following:

	March 31,		December 31,
	2024		2023
	(Unaudited)
Property and equipment, net of accumulated depreciation of $3,105,356    and $2,932,371 as of March 31, 2024 and December 31, 2023, respectively	$	3,879,118	$	2,129,176
Right-of-use operating lease assets		1,725,715		1,862,455
Security deposits and other assets		610,460		634,459
Property and equipment, net, and other assets	$	6,215,293	$	4,626,090

We compute depreciation using the straight-line method over the estimated useful lives of the property and equipment. Depreciation expense for the three months ended March 31, 2024 was $172,985, including $133,793 of depreciation expense reflected within “Cost of revenue” in our condensed consolidated statements of operations as it related to assets used in directly servicing customer contracts. Depreciation expense for the three months ended March 31, 2023 was $238,163, including $84,123 of depreciation expense reflected within “Cost of revenue.”

We purchased 116 compactors, which were previously leased, and related equipment in the first quarter of 2024 for approximately $1.6 million. We purchased an additional 92 compactors and related equipment, which were also previously leased, on April 1, 2024 for approximately $1.5 million. All of the equipment is located at various customer locations. We subsequently financed 80% of the aggregate purchase price with draws on our PNC equipment term loan in the second quarter of 2024. Refer to Note 7, Notes Payable for additional information.

Right-of-use operating lease assets related to our office leases are recognized in accordance with ASC 842. Refer to Note 8, Leases for additional information.

Revolving Credit Facility

On August 5, 2020, QRHC and certain of its domestic subsidiaries entered into a Loan, Security and Guaranty Agreement (the “PNC Loan Agreement”), which was subsequently amended on October 19, 2020, December 7, 2021, August 9, 2022, December 2, 2022, and March 29, 2024 with BBVA USA (which was subsequently succeeded in interest by PNC Bank, National Association (“PNC”)), as a lender, and as administrative agent, collateral agent, and issuing bank, and which provides for a credit facility (the “ABL Facility”) comprising an asset-based revolving credit facility in the maximum principal amount of $35.0 million with a sublimit for issuance of letters of credit of up to 10% of the maximum principal amount of the revolving credit facility. The revolving credit facility bears interest, at the borrowers’ option, at either the Base Rate, plus a margin of 1.25% (no borrowings as of March 31, 2024), or the Term SOFR Rate for the interest period in effect plus a margin of 2.25% (7.73% as of March 31, 2024). The maturity date of the revolving credit facility is April 19, 2026. The PNC Loan Agreement also provides for an equipment term loan facility in the maximum principal amount of $5.0 million. The equipment term loan, which had no borrowings as of March 31, 2024, bears interest, at the borrower’s option, at either the Base Rate, plus a margin of 2.0%, or the Term SOFR Rate for the interest period in effect plus a margin of 3.0%. As further discussed in Note 4, we drew $2.5 million on the equipment term loan in April 2024 to fund 80% of the aggregate purchase price of certain compactors and related equipment.

As of March 31, 2024, the ABL Facility borrowing base availability was $33,067,432, of which $17,480,269 principal was outstanding.

•A senior secured term loan facility in the principal amount of $53.3 million as of March 31, 2024. The senior secured term loan accrues interest at the SOFR Rate for SOFR Loans plus the Applicable Margin; provided, that if the provision of SOFR Loans becomes unlawful or unavailable, then interest will be payable at a rate per annum equal to the Base Rate from time to time in effect plus the Applicable Margin for Base Rate Loans. The maturity date of the term loan facility is October 19, 2026 (the “Maturity Date”). The senior secured term loan will amortize in aggregate annual amounts equal to 1.00% of the

9

original principal amount of the senior secured term loan facility with the balance payable on the Maturity Date. Proceeds of the senior secured term loan are permitted to be used for Permitted Acquisitions (as defined in the Credit Agreement).

•An accordion term loan facility in the maximum principal amount of $5.3 million. Loans under the accordion loan facility may be requested at any time until the Maturity Date. Each accordion term loan shall be on the same terms as those applicable to the senior secured term loan. Proceeds of accordion term loans are permitted to be used for Permitted Acquisitions.

At the same time as the borrowing of the initial $11.5 million under the Credit Agreement in October 2020, in a separate agreement, we issued Monroe Capital a warrant to purchase 500,000 shares of QRHC’s common stock exercisable immediately. For the delayed draw term loan facility, we issued a separate warrant to purchase 350,000 shares upon drawing on this facility on October 19, 2021. Both warrants have an exercise price of $1.50 per share and an expiration date of March 19, 2028. We estimated the value of the warrants issued using the Black Scholes option pricing model and recorded a debt discount (“OID”) of approximately $766,000 in 2020 for the 500,000-share warrant and $536,000 in 2021 for the 350,000-share warrant which are being amortized over the term of the Credit Agreement. We also executed a letter agreement that provides that the warrant holder will receive minimum net proceeds of $1 million less any net proceeds received from the sale of the warrant shares, which is conditional on the full exercise and sale of all the warrant shares at the same time and upon a date two years after the closing date of such agreement.

Green Remedies Promissory Note

On October 19, 2020, we issued an unsecured subordinated promissory note to Green Remedies Waste and Recycling, Inc. in the aggregate principal amount of $2,684,250, payable commencing on January 1, 2021 in quarterly installments through October 1, 2025 and subject to an interest rate of 3.0% per annum.

Interest Expense

The amount of interest expense related to borrowings for the three months ended March 31, 2024 and 2023 was $1,973,716 and $1,956,089, respectively. Interest expense related to amortization of debt issuance fees, and debt discount costs as well as interest related to vendor supply chain financing programs totaled $498,245 and $486,939, respectively, for the three months ended March 31, 2024 and 2023.

8. Leases

Our leases are primarily related to office space and are classified as operating leases.

Lease Costs

For the three months ended March 31, 2024 and 2023, we recorded approximately $178,000 and $190,000, respectively, of fixed cost operating lease expense.

Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the three months ended March 31, 2024 and 2023. We did not obtain any new operating lease right-of-use assets in the three months ended March 31, 2024.

Balance Sheet Classification

The table below presents the lease related assets and liabilities recorded on the balance sheet. Right-of-use assets and related liabilities related to finance leases at March 31, 2024 are de minimis.

9. Revenue

Operating Revenues

We provide businesses with services to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by their operations. Our service revenue is primarily generated from fees charged for the collection, transfer, disposal and recycling services and from sales of commodities by our recycling operations. In addition, we have product sales and other revenue primarily from sales of products such as antifreeze and windshield washer fluid, as well as minor ancillary services.

Revenue Recognition

We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements.

We generally recognize revenue for the gross amount of consideration received when we hold complete responsibility to the customer for contract fulfillment, making us the primary obligor (or principal). Depending on the key terms of the arrangement, which may include situations in which we are not the primary obligor, do not have credit risk, or we determine amounts earned using fixed percentage or fixed fee schedules, we may record the revenue net of certain cost amounts. During the three months ended March 31, 2024 and 2023, we had certain management fee contracts accounted for under the net basis method with net revenue totaling $121,005 and $71,236, respectively. We record amounts collected from customers for sales tax on a net basis.

Disaggregation of Revenue

The following table presents our revenue disaggregated by source. Two customers accounted for an aggregate of 36.3% of revenue for the three months ended March 31, 2024 and two customers accounted for 26.3% of revenue for the three months ended March 31, 2023. We operate primarily in the United States, with minor services in Canada.

	Three Months Ended March 31,
	2024		2023
	(Unaudited)
Revenue Type:
Services	$	69,801,492	$	71,306,740
Product sales and other		2,849,829		2,806,963
Total revenue	$	72,651,321	$	74,113,703

Deferred Revenue

We bill certain customers one month in advance, and, accordingly, we defer recognition of related revenues as a contract liability until the services are provided and control is transferred to the customer. As of March 31, 2024 and December 31, 2023, we had $2,017,261 and $1,509,690, respectively, of deferred revenue which was classified in “Other current liabilities.”

10. Income Taxes

Our statutory income tax rate is anticipated to be approximately 26%. We had income tax expense of $59,348 and $368,504 for the three months ended March 31, 2024 and 2023, respectively, which was attributable to state tax obligations for states with no net operating loss carryforwards, the continuing reserve against the benefit of net operating loss carryforwards at the federal level, and other timing differences.

We compute income taxes using the asset and liability method in accordance with FASB ASC Topic 740, Income Taxes. Under the asset and liability method, we determine deferred income tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities and measure them using currently enacted tax rates and laws. We provide a valuation allowance to reduce the amount of deferred tax assets that, based on available evidence, is more likely than not to be realized. Realization of our deferred tax assets was not reasonably assured as of March 31, 2024 and December 31, 2023, and we had recorded a valuation allowance of $17,565,000 and $17,413,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2024 and December 31, 2023, we had federal income tax net operating loss carryforwards of approximately $3,200,000 and $5,900,000, respectively, which expire at various dates ranging from 2034-2037.

11

11. Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, and notes payable. We do not believe that we are exposed to significant currency or credit risks arising from these financial instruments. Our variable rate indebtedness subjects us to interest rate risk as all of the borrowings under the senior secured credit facilities bear interest at variable rates. The fair values of our financial instruments approximate their carrying values, based on their short maturities or, for notes payable, based on borrowing rates currently available to us for loans with similar terms and maturities. Contingent liabilities are measured at fair value on a recurring basis. The fair value measurements are generally determined using unobservable inputs and are classified within Level 3 of the fair value hierarchy.

12. Stockholders’ Equity

Preferred Stock – Our authorized preferred stock consists of 10,000,000 shares of preferred stock with a par value of $0.001, of which no shares have been issued or are outstanding.

Common Stock – Our authorized common stock consists of 200,000,000 shares of common stock with a par value of $0.001, of which 20,229,821 and 20,161,400 shares were issued and outstanding as of March 31, 2024 and December 31, 2023, respectively.

Employee Stock Purchase Plan – On September 17, 2014, our stockholders approved our 2014 Employee Stock Purchase Plan (as amended, the “ESPP”). We recorded expense of $20,551 and $22,910 related to the ESPP for the three months ended March 31, 2024 and 2023, respectively.

Warrants – The following table summarizes the warrants issued and outstanding as of March 31, 2024:

Warrants Issued and Outstanding as of March 31, 2024
	Date of		Exercise		Shares of
Description	Issuance	Expiration			Common Stock
Exercisable Warrants	10/19/2020	3/19/2028	$	1.50		500,000
Exercisable Warrants	10/19/2021	3/19/2028	$	1.50		350,000
Total warrants issued and outstanding (Unaudited)						850,000

Stock Options – We recorded stock option expense of $145,816 and $250,254 for the three months ended March 31, 2024 and 2023, respectively. The following table summarizes the stock option activity for the three months ended March 31, 2024:

	Stock Options
					Weighted-
				Exercise	Average
	Number			Price Per	Exercise Price
	of Shares			Share	Per Share
Outstanding at December 31, 2023		2,869,013		$1.17 — $23.20	$	3.33
Exercised		(68,421	)	$3.83  — $6.40	$	4.79
Cancelled/Forfeited		(30,328	)	$1.83  — $6.30	$	3.55
Outstanding at March 31, 2024 (Unaudited)		2,770,264		$1.17 — $23.20	$	3.29

Deferred Stock Units – Nonemployee directors can elect to receive all or a portion of their annual retainers in the form of deferred stock units (“DSUs”). The DSUs are recognized at their fair value on the date of grant. Each DSU represents the right to receive one share of our common stock following the completion of a director’s service. During the three months ended March 31, 2024, we granted 2,772 DSUs and recorded director compensation expense of $20,598 related to the grants. In addition, during the three months ended March 31, 2024, we granted 1,195 DSUs to executive employees and recorded compensation expense of $58,329, which includes an accrual of anticipated bonus expense to be paid in DSUs for certain executive employees. We had 235,602 and 231,635 DSUs outstanding at March 31, 2024 and December 31, 2023, respectively.

Restricted Stock Units - Restricted Stock Units (“RSUs”) are recognized at their fair value on the date of grant. Each RSU represents the right to receive one share of our common stock once fully vested. All outstanding unvested RSUs currently have one year vesting terms. During the three months ended March 31, 2024, we recorded director compensation expense of $111,576 related to 2023 RSU grants. We had 61,056 RSUs outstanding at March 31, 2024 and December 31, 2023. These RSUs were not vested at March 31, 2024.

12

13. Net Loss per Share

We compute basic net loss per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for DSUs during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods where losses are reported, the weighted average number of shares of common stock outstanding excludes common stock equivalents because their inclusion would be anti-dilutive. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options and warrants. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method.

The computation of basic and diluted net loss per share attributable to common stockholders is as follows:

Business Overview

We are a national provider of waste and recycling services to customers from across multiple industry sectors that are typically larger, multi-location businesses. We create customer-specific programs and perform the related services for the collection, processing, recycling, disposal, and tracking of waste streams and recyclables. We also provide information and data that tracks and reports the detailed transactional and environmental results of our services and provides actionable data to improve business operations. The data we generate also enables our customers to address their business, sustainability, environmental, social and governance goals and responsibilities.

Our revenue is primarily generated from fees charged for our collection, transfer, disposal and services for both solid waste and recyclable materials and from sales of recyclable materials. In addition, we have product sales and other revenue primarily from sales of products such as antifreeze and windshield washer fluid, as well as minor ancillary services.

This “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is based on and relates primarily to the operations of QRHC and QRMG (collectively, “we,” “us,” “our,” or “our company”).

Three Months Ended March 31, 2024 and 2023 Operating Results

Three Months Ended March 31, 2024, compared to Three Months Ended March 31, 2023

Global Economic Trends

There has been heightened uncertainty in the macroeconomic environment, and concerns that the U.S. economy may fall into a recession since the Federal Reserve began aggressively raising interest rates in March 2022 to address persistently high inflation. There are also significant geopolitical concerns, including the current conflict between Ukraine and Russia and the Israel-Hamas war, which have created extreme volatility in the global capital markets and are expected to have further global economic consequences, including disruptions of the global supply chain and energy markets. Any such volatility and disruptions may have adverse consequences on us or the third parties on whom we rely. If the equity and credit markets continue to deteriorate, including as a result of political unrest or war, it may make any necessary debt or equity financing more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive. Inflation can adversely affect us by increasing our costs, including salary costs. Any significant increases in inflation and related increases in interest rates could have a material adverse effect on our business, results of operations and financial condition.

Revenue

For the quarter ended March 31, 2024, revenue was $72.7 million, a decrease of $1.5 million, or 2.0%, compared to $74.1 million for the quarter ended March 31, 2023.

The slight decline in revenue was attributable to lower volumes from three customers, whose margins were lower overall than the rest of the business, resulting in a decrease of revenues of approximately $7 million. This was partially offset by strong overall demand for the remaining business which contributed approximately $5 million in additional revenue, an increase of 8% from the same period in 2023.

Cost of Revenue/Gross Profit

Cost of revenue decreased $2.9 million to $58.6 million for the quarter ended March 31, 2024 from $61.5 million for the quarter ended March 31, 2023. The changes were primarily due to the same reasons impacting the decrease in revenue.

Gross profit for the quarter ended March 31, 2024 was $14.0 million, an increase of $1.4 million, compared to $12.6 million for the quarter ended March 31, 2023. The gross profit margin was 19.3% for the quarter ended March 31, 2024 compared to 17.0% for the same quarter of 2023. The changes in gross profit and gross profit margin percentage for the quarter were primarily due to the net impacts of the changes in both revenue and cost of revenue combined with broad margin gains across most of our business.

Revenue, gross profit, and gross profit margins are affected period to period by the volumes of waste and recyclable materials generated by our customers, the frequency and type of services provided, the price and mix of the services provided, price changes for recyclable materials, the cost and mix of subcontracted services provided in any one reporting period, and the timing of acquisitions and integration. Volumes of waste and recyclable materials generated by our customers is impacted period to period based on several factors including their production or sales levels, demand of their product or services in the market, supply chain reliability, and labor force stability, among other business factors.

Operating Expenses

Operating expenses were $12.2 million and $11.8 million for the quarters ended March 31, 2024 and 2023, respectively.

Selling, general, and administrative expenses were $9.8 million and $9.4 million for the quarters ended March 31, 2024 and 2023, respectively. Selling, general, and administrative expenses for the quarter were mostly flat compared to the prior year period.

Operating expenses for the quarters ended March 31, 2024 and 2023 included depreciation and amortization of $2.4 million and $2.4 million, respectively.

Interest Expense

Interest expense was $2.5 million and $2.4 million for the quarters ended March 31, 2024 and 2023, respectively. The slight increase is primarily due to increases in base interest rates, partially offset by reduced borrowings from voluntary paydowns on the term loan in 2023. We are amortizing debt issuance costs of $3.7 million and OID of $1.8 million to interest expense over the life of the related debt arrangements as discussed in Note 7 to our condensed consolidated financial statements.

Income Taxes

We recorded a provision for income tax of $59,348 and $368,504 for the quarters ended March 31, 2024 and 2023, respectively. The provision for income tax is primarily attributable to state tax obligations based on current estimated state tax apportionments for states with no net operating loss carryforwards.

We recorded a full valuation allowance against all our deferred tax assets (“DTAs”) as of both March 31, 2024 and December 31, 2023. We intend on maintaining a full valuation allowance on our DTAs until there is sufficient evidence to support the reversal of all

15

or some portion of these allowances. However, given our current earnings and anticipated future earnings, we believe that there is a reasonable possibility that within the next 12 to 24 months, sufficient positive evidence may become available to allow us to reach a conclusion that a significant portion of the valuation allowance will no longer be needed. Release of the valuation allowance would result in the recognition of certain DTAs and a decrease to income tax expense for the period the release is recorded. However, the exact timing and amount of the valuation allowance release are subject to change based on the level of profitability that we are able to actually achieve.

Net Loss

Net loss for the quarter ended March 31, 2024 was $(0.7) million compared to net loss of $(2.0) million for the quarter ended March 31, 2023. The explanations above detail the majority of the changes related to the change in net results.

Our operating results, including revenue, operating expenses, and operating margins, will vary from period to period depending on commodity prices of recyclable materials, the volumes and mix of services provided, as well as customer mix during the reporting period, and the timing of acquisitions and integration.

Loss per Share

Net loss per basic and diluted share attributable to common stockholders was $(0.03) and $(0.10) for the quarters ended March 31, 2024 and 2023, respectively.

The basic and diluted weighted average number of shares of common stock outstanding were approximately 20.4 million and 19.9 million for the three months ended March 31, 2024 and 2023, respectively.

Adjusted EBITDA

For the three months ended March 31, 2024, Adjusted EBITDA (as defined below), a non-GAAP financial measure, increased 28.4% to $5.1 million from $4.0 million for the three months ended March 31, 2023.

We use the non-GAAP measurement of earnings before interest, taxes, depreciation, amortization, stock-related compensation charges, and other adjustments, or “Adjusted EBITDA,” to evaluate our performance. Adjusted EBITDA is a non-GAAP measure that is also frequently used by analysts, investors and other interested parties to evaluate the market value of companies considered to be in similar businesses. We suggest that Adjusted EBITDA be viewed in conjunction with our reported financial results or other financial information prepared in accordance with GAAP. For the three months ended March 31, 2024, other adjustments included certain professional fees as well as certain administrative fees related to borrowings. For the three months ended March 31, 2023, other adjustments included earn-out adjustments, severance and project costs as well as certain administrative costs related to borrowings.

The following table reflects the reconciliation of net loss to Adjusted EBITDA for the three months ended March 31, 2024 and 2023:

	As Reported
	Three Months Ended March 31,
	2024			2023
	(Unaudited)

Income tax expense		59,348			368,504
Adjusted EBITDA	$	5,120,104		$	3,986,885

Adjusted Net Income and Adjusted Net Income per Diluted Share

Adjusted net income, a non-GAAP financial measure, was $1.7 million for the three months ended March 31, 2024, compared with $0.6 million for the three months ended March 31, 2023. We present adjusted net income and adjusted net income per diluted share, both non-GAAP financial measures, supplementally because they are widely used by investors as a valuation measure in the solid waste industry. Management uses adjusted net income and adjusted net income per diluted share as two of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We provide adjusted net income to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income has limitations due to the fact that it excludes items that have an impact on our financial condition and results of operations. Adjusted net income and adjusted net income per diluted share are not a substitute for, and should be used in conjunction with, GAAP financial measures. Other

16

companies may calculate these non-GAAP financial measures differently. Our adjusted net income and adjusted net income per diluted share for the three months ended March 31, 2024 and 2023 are calculated as follows:

As of March 31, 2024 and December 31, 2023, we had $0.6 million and $0.3 million in cash and cash equivalents, respectively. Working capital was $19.8 million and $15.7 million as of March 31, 2024 and December 31, 2023, respectively.

We derive our primary sources of funds for conducting our business activities from operating revenues; borrowings under our credit facilities; and the placement of our equity securities to investors. We require working capital primarily to carry accounts receivable, service debt, purchase capital assets, fund operating expenses, address unanticipated competitive threats or technical problems, withstand adverse economic conditions, fund potential acquisition transactions, and pursue goals and strategies.

We believe our existing cash and cash equivalents of $0.6 million, our borrowing availability under our $35.0 million ABL Facility (as defined and discussed in Note 7 to our condensed consolidated financial statements), and cash expected to be generated from operations will be sufficient to fund our operations for the next 12 months and thereafter for the foreseeable future. Our known current- and long-term uses of cash include, among other possible demands, capital expenditures, lease payments and repayments to service debt and other long-term obligations. We have no agreements, commitments, or understandings with respect to any such placements of our securities and any such placements could be dilutive to our stockholders.

Cash Flows

The following discussion relates to the major components of our cash flows for the three months ended March 31, 2024 and 2023.

Cash Flows from Operating Activities

Net cash used in operating activities was $(1.7) million for the three months ended March 31, 2024 compared with net cash provided by operating activities of $3.0 million for the three months ended March 31, 2023.

Net cash used in operating activities for the three months ended March 31, 2024 related primarily to the net effect of the following:

•net loss of $(0.7) million;

•non-cash items of $3.7 million, which primarily related to depreciation, amortization of intangible assets and debt issuance costs, provision for doubtful accounts, and stock-based compensation; and

•net cash used in the net change in operating assets and liabilities of $(4.7) million, primarily associated with relative changes in accounts receivable, accounts payable, and accrued liabilities. This includes an earn-out payment of $(1.0) million.

17

Net cash provided by operating activities for the three months ended March 31, 2023 related primarily to the net effect of the following:

•net loss of $(2.0) million;

•non-cash items of $3.3 million, which primarily related to depreciation, amortization of intangible assets and debt issuance costs, provision for doubtful accounts, and stock-based compensation; and

•net cash provided by the net change in operating assets and liabilities of $1.7 million, primarily associated with relative changes in accounts receivable, accounts payable, and accrued liabilities.

Our business, including revenue, operating expenses, and operating margins, may vary depending on the blend of services we provide to our customers, the terms of customer contracts, recyclable materials contracts, and our business volume levels. Fluctuations in net accounts receivable are generally attributable to a variety of factors including, but not limited to, the timing of cash receipts from customers, and the inception, increase, modification, or termination of customer relationships. Our operating activities may require additional cash in the future from our debt facilities and/or equity financings depending on the level of our operations.

Cash Flows from Investing Activities

Cash used in investing activities for the three months ended March 31, 2024 was $(2.3) million and primarily related to the purchase of $(1.6) million in compactors and related equipment. Cash used in investing activities for the three months ended March 31, 2023 was $(0.2) million. Other investing activities are primarily from purchases of intangible assets such as software development costs and other property and equipment.

Cash Flows from Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2024 was $4.2 million, primarily from net borrowings of $4.2 million on our ABL Facility. Net cash used in financing activities for the three months ended March 31, 2023 was $(2.5) million, primarily from net repayments of $2.3 million on our ABL Facility. See Note 7 to our condensed consolidated financial statements for a discussion of the ABL Facility and other notes payable.

Inflation

Although the overall economy has experienced some inflationary pressures, we do not believe that inflation had a material impact on us during the three months ended March 31, 2024 and 2023. We believe that current inflationary increases in costs, such as fuel, labor, and certain capital items, can be addressed by our flexible pricing structures and cost recovery fees allowing us to recover certain of the cost of inflation from our customer base. Consistent with industry practice, many of our contracts allow us to pass through certain costs to our customers or adjust pricing. Although we believe that we should be able to offset many cost increases that result from inflation in the ordinary course of business, we may be required to absorb at least part of these costs increases due to competitive pressures or delays in timing of rate increases. Although we have not been materially affected by inflation in the past, we can provide no assurance that we will not be affected in the future by higher rates of inflation and increases in interest rates.

Critical Accounting Estimates and Policies

Our discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. These areas include carrying amounts of accounts receivable, goodwill and other intangible assets, stock-based compensation expense, deferred taxes and the fair value of assets and liabilities acquired in asset acquisitions. We base our estimates on historical experience, our observance of trends in particular areas, and information or valuations and various other assumptions that we believe to be reasonable under the circumstances and which form the basis for making judgments about the carrying value of assets and liabilities that may not be readily apparent from other sources. Actual amounts could differ significantly from amounts previously estimated. For a discussion of our critical accounting policies, refer to Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2023 Annual Report. There have been no significant changes in our critical accounting policies during the three months ended March 31, 2024.

Off-Balance Sheet Arrangements

We have no off-balance sheet debt or similar obligations. We have no transactions or obligations with related parties that are not disclosed, consolidated into, or reflected in our reported results of operations or financial position. We do not guarantee any third-party debt.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of March 31, 2024.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error 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, misstatements, errors, and instances of fraud, if any, within our company have been or will be prevented or 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. Controls also can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. We base the design of any system of controls in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, internal controls may become inadequate as a result of changes in conditions, or through the deterioration of the degree of compliance with policies or procedures.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Principles of Presentation and Consolidation

The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2023. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading.

The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at March 31, 2024 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2023 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary.

All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires incremental disclosures related to reportable segments, including significant segment expense categories and amounts for each reportable segment. Entities with a single reportable segment are required to provide the new disclosures required under Accounting Standards Codification (“ASC”) 280. This authoritative guidance is required to be applied retrospectively and will be effective for our annual disclosures beginning in 2024 and interim periods starting 2025. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires entities to provide additional disclosure related to the transparency and decision usefulness of income tax disclosures, including additional disclosure around the rate reconciliation and income taxes paid. The authoritative guidance should be applied prospectively and will be effective for us starting in 2025. Retrospective application is permitted. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.

Receivables [Abstract]

Accounts Receivable, Net of Allowance For Doubtful Accounts

3. Accounts Receivable, Net of Allowance for Doubtful Accounts

Our receivables, which are recorded when billed or when services are performed, are claims against third parties that will generally be settled in cash. The carrying value of our receivables, net of the allowance for doubtful accounts, represents the estimated net realizable value. We estimate our allowance for doubtful accounts based on consideration of a number of factors, including the length of time trade accounts are past due, our previous loss history, the creditworthiness of individual customers, economic conditions

affecting specific customer industries, and economic conditions in general. We write off past-due receivable balances after all reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to bad debt expense in the period we receive the payment.

The following table reflects the activity in our allowance for doubtful accounts of trade receivables for the three months ended March 31, 2024 and 2023:

	Three Months Ended March 31,
	2024			2023

Depreciation expense for the three months ended March 31, 2023 was $238,163, including $84,123 of depreciation expense reflected within “Cost of revenue.”

We purchased 116 compactors, which were previously leased, and related equipment in the first quarter of 2024 for approximately $1.6 million. We purchased an additional 92 compactors and related equipment, which were also previously leased, on April 1, 2024 for approximately $1.5 million. All of the equipment is located at various customer locations. We subsequently financed 80% of the aggregate purchase price with draws on our PNC equipment term loan in the second quarter of 2024. Refer to Note 7, Notes Payable for additional information.

Revolving Credit Facility

On August 5, 2020, QRHC and certain of its domestic subsidiaries entered into a Loan, Security and Guaranty Agreement (the “PNC Loan Agreement”), which was subsequently amended on October 19, 2020, December 7, 2021, August 9, 2022, December 2, 2022, and March 29, 2024 with BBVA USA (which was subsequently succeeded in interest by PNC Bank, National Association (“PNC”)), as a lender, and as administrative agent, collateral agent, and issuing bank, and which provides for a credit facility (the “ABL Facility”) comprising an asset-based revolving credit facility in the maximum principal amount of $35.0 million with a sublimit for issuance of letters of credit of up to 10% of the maximum principal amount of the revolving credit facility. The revolving credit facility bears interest, at the borrowers’ option, at either the Base Rate, plus a margin of 1.25% (no borrowings as of March 31, 2024), or the Term SOFR Rate for the interest period in effect plus a margin of 2.25% (7.73% as of March 31, 2024). The maturity date of the revolving credit facility is April 19, 2026. The PNC Loan Agreement also provides for an equipment term loan facility in the maximum principal amount of $5.0 million. The equipment term loan, which had no borrowings as of March 31, 2024, bears interest, at the borrower’s option, at either the Base Rate, plus a margin of 2.0%, or the Term SOFR Rate for the interest period in effect plus a margin of 3.0%. As further discussed in Note 4, we drew $2.5 million on the equipment term loan in April 2024 to fund 80% of the aggregate purchase price of certain compactors and related equipment.

As of March 31, 2024, the ABL Facility borrowing base availability was $33,067,432, of which $17,480,269 principal was outstanding.

Monroe Term Loan

On October 19, 2020, QRHC and certain of its domestic subsidiaries entered into a Credit Agreement (the “Credit Agreement”), dated as of October 19, 2020, which was subsequently amended on September 3, 2021, December 1, 2021, December 7, 2021, December 2, 2022, and March 29, 2024 with Monroe Capital Management Advisors, LLC (“Monroe Capital”), as administrative agent for the lenders thereto. Among other things, the Credit Agreement provides for the following:

•A senior secured term loan facility in the principal amount of $53.3 million as of March 31, 2024. The senior secured term loan accrues interest at the SOFR Rate for SOFR Loans plus the Applicable Margin; provided, that if the provision of SOFR Loans becomes unlawful or unavailable, then interest will be payable at a rate per annum equal to the Base Rate from time to time in effect plus the Applicable Margin for Base Rate Loans. The maturity date of the term loan facility is October 19, 2026 (the “Maturity Date”). The senior secured term loan will amortize in aggregate annual amounts equal to 1.00% of the

original principal amount of the senior secured term loan facility with the balance payable on the Maturity Date. Proceeds of the senior secured term loan are permitted to be used for Permitted Acquisitions (as defined in the Credit Agreement).

•An accordion term loan facility in the maximum principal amount of $5.3 million. Loans under the accordion loan facility may be requested at any time until the Maturity Date. Each accordion term loan shall be on the same terms as those applicable to the senior secured term loan. Proceeds of accordion term loans are permitted to be used for Permitted Acquisitions.

At the same time as the borrowing of the initial $11.5 million under the Credit Agreement in October 2020, in a separate agreement, we issued Monroe Capital a warrant to purchase 500,000 shares of QRHC’s common stock exercisable immediately. For the delayed draw term loan facility, we issued a separate warrant to purchase 350,000 shares upon drawing on this facility on October 19, 2021. Both warrants have an exercise price of $1.50 per share and an expiration date of March 19, 2028. We estimated the value of the warrants issued using the Black Scholes option pricing model and recorded a debt discount (“OID”) of approximately $766,000 in 2020 for the 500,000-share warrant and $536,000 in 2021 for the 350,000-share warrant which are being amortized over the term of the Credit Agreement. We also executed a letter agreement that provides that the warrant holder will receive minimum net proceeds of $1 million less any net proceeds received from the sale of the warrant shares, which is conditional on the full exercise and sale of all the warrant shares at the same time and upon a date two years after the closing date of such agreement.

Green Remedies Promissory Note

On October 19, 2020, we issued an unsecured subordinated promissory note to Green Remedies Waste and Recycling, Inc. in the aggregate principal amount of $2,684,250, payable commencing on January 1, 2021 in quarterly installments through October 1, 2025 and subject to an interest rate of 3.0% per annum.

Interest Expense

The amount of interest expense related to borrowings for the three months ended March 31, 2024 and 2023 was $1,973,716 and $1,956,089, respectively. Interest expense related to amortization of debt issuance fees, and debt discount costs as well as interest related to vendor supply chain financing programs totaled $498,245 and $486,939, respectively, for the three months ended March 31, 2024 and 2023.

Revenue from Contract with Customer [Abstract]

Revenue

9. Revenue

Operating Revenues

We provide businesses with services to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by their operations. Our service revenue is primarily generated from fees charged for the collection, transfer, disposal and recycling services and from sales of commodities by our recycling operations. In addition, we have product sales and other revenue primarily from sales of products such as antifreeze and windshield washer fluid, as well as minor ancillary services.

Revenue Recognition

We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements.

We generally recognize revenue for the gross amount of consideration received when we hold complete responsibility to the customer for contract fulfillment, making us the primary obligor (or principal). Depending on the key terms of the arrangement, which may include situations in which we are not the primary obligor, do not have credit risk, or we determine amounts earned using fixed percentage or fixed fee schedules, we may record the revenue net of certain cost amounts. During the three months ended March 31, 2024 and 2023, we had certain management fee contracts accounted for under the net basis method with net revenue totaling $121,005 and $71,236, respectively. We record amounts collected from customers for sales tax on a net basis.

Disaggregation of Revenue

The following table presents our revenue disaggregated by source. Two customers accounted for an aggregate of 36.3% of revenue for the three months ended March 31, 2024 and two customers accounted for 26.3% of revenue for the three months ended March 31, 2023. We operate primarily in the United States, with minor services in Canada.

Total revenue	$	72,651,321	$	74,113,703

Deferred Revenue

We bill certain customers one month in advance, and, accordingly, we defer recognition of related revenues as a contract liability until the services are provided and control is transferred to the customer. As of March 31, 2024 and December 31, 2023, we had $2,017,261 and $1,509,690, respectively, of deferred revenue which was classified in “Other current liabilities.”

10. Income Taxes

Our statutory income tax rate is anticipated to be approximately 26%. We had income tax expense of $59,348 and $368,504 for the three months ended March 31, 2024 and 2023, respectively, which was attributable to state tax obligations for states with no net operating loss carryforwards, the continuing reserve against the benefit of net operating loss carryforwards at the federal level, and other timing differences.

We compute income taxes using the asset and liability method in accordance with FASB ASC Topic 740, Income Taxes. Under the asset and liability method, we determine deferred income tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities and measure them using currently enacted tax rates and laws. We provide a valuation allowance to reduce the amount of deferred tax assets that, based on available evidence, is more likely than not to be realized. Realization of our deferred tax assets was not reasonably assured as of March 31, 2024 and December 31, 2023, and we had recorded a valuation allowance of $17,565,000 and $17,413,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2024 and December 31, 2023, we had federal income tax net operating loss carryforwards of approximately $3,200,000 and $5,900,000, respectively, which expire at various dates ranging from 2034-2037.

Fair Value of Financial Instruments

11. Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, and notes payable. We do not believe that we are exposed to significant currency or credit risks arising from these financial instruments. Our variable rate indebtedness subjects us to interest rate risk as all of the borrowings under the senior secured credit facilities bear interest at variable rates. The fair values of our financial instruments approximate their carrying values, based on their short maturities or, for notes payable, based on borrowing rates currently available to us for loans with similar terms and maturities. Contingent liabilities are measured at fair value on a recurring basis. The fair value measurements are generally determined using unobservable inputs and are classified within Level 3 of the fair value hierarchy.

Deferred Stock Units – Nonemployee directors can elect to receive all or a portion of their annual retainers in the form of deferred stock units (“DSUs”). The DSUs are recognized at their fair value on the date of grant. Each DSU represents the right to receive one share of our common stock following the completion of a director’s service. During the three months ended March 31, 2024, we granted 2,772 DSUs and recorded director compensation expense of $20,598 related to the grants. In addition, during the three months ended March 31, 2024, we granted 1,195 DSUs to executive employees and recorded compensation expense of $58,329, which includes an accrual of anticipated bonus expense to be paid in DSUs for certain executive employees. We had 235,602 and 231,635 DSUs outstanding at March 31, 2024 and December 31, 2023, respectively.

Restricted Stock Units - Restricted Stock Units (“RSUs”) are recognized at their fair value on the date of grant. Each RSU represents the right to receive one share of our common stock once fully vested. All outstanding unvested RSUs currently have one year vesting terms. During the three months ended March 31, 2024, we recorded director compensation expense of $111,576 related to 2023 RSU grants. We had 61,056 RSUs outstanding at March 31, 2024 and December 31, 2023. These RSUs were not vested at March 31, 2024.

Earnings Per Share [Abstract]

Net Loss per Share

13. Net Loss per Share

We compute basic net loss per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for DSUs during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods where losses are reported, the weighted average number of shares of common stock outstanding excludes common stock equivalents because their inclusion would be anti-dilutive. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options and warrants. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method.

The computation of basic and diluted net loss per share attributable to common stockholders is as follows:

Accounting Policies [Abstract]

Principles of Presentation and Consolidation

Principles of Presentation and Consolidation

The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2023. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading.

The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at March 31, 2024 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2023 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary.

All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires incremental disclosures related to reportable segments, including significant segment expense categories and amounts for each reportable segment. Entities with a single reportable segment are required to provide the new disclosures required under Accounting Standards Codification (“ASC”) 280. This authoritative guidance is required to be applied retrospectively and will be effective for our annual disclosures beginning in 2024 and interim periods starting 2025. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires entities to provide additional disclosure related to the transparency and decision usefulness of income tax disclosures, including additional disclosure around the rate reconciliation and income taxes paid. The authoritative guidance should be applied prospectively and will be effective for us starting in 2025. Retrospective application is permitted. This guidance is only related to disclosures and is not expected to have a significant impact on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.
