**SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. Any statements contained in this Quarterly Report on Form 10-Q that are not statements of historical facts, including statements regarding our future results of operations and financial position, business strategy and plans, objectives of management for future operations, long term operating expenses, and expectations for capital requirements, may be deemed to be forward-looking statements.

These statements involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from the information expressed or implied by these forward-looking statements.

These forward-looking statements reflect our management's beliefs and views with respect to future events and are based on estimates and assumptions as of the date of this Quarterly Report on Form 10-Q and are subject to risks and uncertainties. Actual results could differ materially from those contained in these forward-looking statements for a variety of reasons, including, but not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 31, 2024, Part I, Item 1A, "Risk Factors," as well as those discussed elsewhere in this Quarterly Report. As a result of these factors, we cannot assure you that the forward-looking statements in this Quarterly Report on Form 10-Q will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified timeframe, or at all. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe that such information provides a reasonable basis for these statements, such information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on them.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance, or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. Such forward-looking statements relate only to events as of the date of this Quarterly Report on Form 10-Q. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report on Form 10-Q to conform these statements to actual results or to changes in our expectations, except as required by law.

You should read this Quarterly Report on Form 10-Q and the documents that we reference and have filed as exhibits with the understanding that our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements in this Quarterly Report on Form 10-Q by these cautionary statements.

The Company was incorporated in the state of Delaware on March 10, 2000 and is headquartered in New York, NY.

***Basis of Presentation***

The accompanying condensed consolidated financial statements are prepared in accordance with the accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K (the "Form 10-K") for the year ended December 31, 2024, filed with the Securities and Exchange Commission ("SEC") on March 3, 2025.

The consolidated balance sheet as of December 31, 2024, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including certain notes required by GAAP on an annual reporting basis.

In the opinion of the Company, the accompanying condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of its financial position and its results of operations, changes in stockholders' equity, and cash flows for the interim periods. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for any subsequent quarter or for the year ending December 31, 2025.

There have been no material changes to the Company's significant accounting policies as described in the Form 10-K.

***Restructuring Charges***

During the three and nine months ended September 30, 2025, the Company incurred $0.8 million of employee severance and benefits costs relating to a reorganization intended to improve operational and cost efficiency. During the year ended December 31, 2024, the Company incurred $1.4 million of employee severance and benefits costs relating to a workforce reduction.

The majority of the remaining $1.0 million of severance accrued as of September 30, 2025 is anticipated to be paid during the year ending December 31, 2025, while approximately $0.1 million is expected to be paid during the first quarter of 2026.

The following table displays a rollforward of the charges and payments to the accrued balance as of September 30, 2025:

---

| | |
|:---|:---|
| **(in thousands)** | **Restructuring Charges** |
| Balance, December 31, 2024 | $1262 |
| Restructuring charges | 802 |
| Cash payments | (1080) |
| Balance, September 30, 2025 | $984 |

---

During the three and nine months ended September 30, 2025 there was $0.8 million of restructuring charges recorded in sales and marketing expense in the condensed consolidated statements of operations. During the three months ended September 30, 2024, there was no restructuring expense recorded.

***Use of Estimates***

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, revenue recognition, provision for transaction losses, allowance for doubtful accounts, impairment assessment of goodwill, the determination of useful lives, income taxes, and the valuation of leases. The Company evaluates its estimates and assumptions on an ongoing basis. Actual results could differ from those estimates and such differences may be material to the condensed consolidated financial statements.

***Segment Information***

An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision maker ("CODM"). The Company operates and manages its business as one reportable and operating segment. The Company's chief executive officer, who is the chief operating decision maker, reviews financial information on a consolidated basis for purposes of evaluating financial performance and allocating resources. The Company's single reportable and operating segment contains one reporting unit, which consists of the Company's online marketplace that enables commerce between sellers and buyers. The CODM regularly reviews the GAAP consolidated statement of operations from a significant expense perspective when evaluating financial performance and allocating resources. While the CODM also reviews other funnel metrics regularly (i.e. Gross Merchandise Value ("GMV"), Number of Orders, etc.), there are no additional significant segment expenses other than those disclosed in the condensed consolidated statements of operations.

***Cash, Cash Equivalents, and Restricted Cash***

The following represents the Company's cash, cash equivalents, and restricted cash as of the periods presented:

---

| | | |
|:---|:---|:---|
| **(in thousands)** | **September 30, 2025** | **September 30, 2024** |
| Cash and cash equivalents | $19938 | $22018 |
| Restricted cash, non-current | 3696 | 3641 |
| Total cash, cash equivalents, and restricted cash | $23634 | $25659 |

---

The Company considers all short-term, highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Certain cash equivalents consist of investments in debt securities that are classified as available-for-sale. As of September 30, 2025 and 2024, the Company's restricted cash, non-current relates to $3.7 million and $3.6 million in Letters of Credit for its office leases, respectively. The carrying value of the restricted cash approximates fair value. During the three and nine months ended September 30, 2025, the Company purchased $2.9 million and $15.2 million of available-for-sale securities classified as cash equivalents, respectively. During the three and nine months ended September 30, 2024 the Company purchased zero and $25.6 million of available-for-sale securities classified as cash equivalents, respectively.

***Recently Issued Accounting Pronouncements***

In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2025-06 – Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which simplifies the capitalization guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The amendments in this update permit an entity to apply the new guidance using a prospective, retrospective or modified transition approach. The Company is currently in the process of evaluating the effects of this pronouncement on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides all entities with a practical expedient of developing reasonable and supportable forecasts as part of estimating expected credit losses, that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently in the process of evaluating the effects of this pronouncement on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures. The standard will require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The new standard is effective for annual periods beginning after December 15, 2024. The Company adopted the standard during the year ended December 31, 2025. Adoption requires additional disclosures in the December 31, 2025 Form 10-K and will not have a financial impact on the Company's consolidated balance sheets and statement of operations.

**2. Fair Value of Financial Instruments**

Certain assets and liabilities are carried at fair value in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Valuation techniques used to measure fair value require the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1—Quoted prices in active markets for identical assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies, and similar techniques.

Sublease income is recognized as an offset to lease expense on a straight-line basis over the lease term and is included in general and administrative expenses on the Company's condensed consolidated statement of operations. The sublease ends on December 31, 2029, the expiration date of the Company's former New York City headquarter's lease. In November 2023, the Company entered into a lease agreement, as the lessee, for the Company's new corporate headquarters in New York City (the "Lease Agreement") which commenced in January 2024 with a five year term and an option to extend the lease for an additional five years.

***Stock-Based Compensation Expense***

The following table summarizes the classification of the Company's stock-based compensation expense in the condensed consolidated statements of operations:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **(in thousands)** | **Three Months Ended September 30,** | **Three Months Ended September 30,** | **Nine Months Ended September 30,** | **Nine Months Ended September 30,** |
| **(in thousands)** | **2025** | **2024** | **2025** | **2024** |
| Cost of revenue | $89 | $86 | $277 | $253 |
| Sales and marketing | 670 | 975 | 2194 | 2686 |
| Technology development | 896 | 1050 | 2869 | 2824 |
| General and administrative | 1591 | 1791 | 5498 | 5245 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total stock-based compensation expense | $3246 | $3902 | $10838 | $11008 |

---

Stock-based compensation costs capitalized in connection with the Company's internal-use software was less than $0.1 million for the three and nine months ended September 30, 2025, and the three months ended September 30, 2024. For the nine months ended September 30, 2024, stock-based compensation costs capitalized in connection with the Company's internal-use software was $0.1 million. As of September 30, 2025, total unrecognized compensation expense related to unvested stock-based awards was $18.1 million, which is expected to be recognized over a weighted-average period of 2.1 years.

**11. Income Taxes**

The Company's income tax provision was immaterial for the three and nine months ended September 30, 2025 and 2024 due to the net loss before income taxes expected to be incurred for the year ending December 31, 2025 and incurred for the year ended December 31, 2024, as well as the Company's continued maintenance of a full valuation allowance against its net deferred tax assets. The Company's history of pre-tax losses represents sufficient evidence to establish and continue to maintain a full valuation allowance is appropriate. As of September 30, 2025, the Company had no material liabilities for interest and penalties accrued.

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law in the U.S., which contains a broad range of tax reform provisions affecting businesses. The Company is in the process of evaluating the impact of OBBBA to its financial statements. However, it is currently not expected to have a material impact.

**12. Net Loss Per Share**

The following table summarizes the computation of basic and diluted net loss per share for the three and nine months ended September 30, 2025 and 2024:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended September 30,** | **Three Months Ended September 30,** | **Nine Months Ended September 30,** | **Nine Months Ended September 30,** |
| **(in thousands, except share and per share amounts)** | **2025** | **2024** | **2025** | **2024** |
| **Numerator:** |  |  |  |  |
| Net loss | $(3506) | $(5683) | $(12625) | $(13423) |
| **Denominator:** |  |  |  |  |
| Weighted average common shares outstanding—basic and diluted | 36338544 | 36719249 | 35913430 | 38321518 |
| Net loss per share—basic and diluted | $(0.10) | $(0.15) | $(0.35) | $(0.35) |

---

The Company's potentially dilutive securities, which include outstanding stock options and restricted stock units have been excluded from the computation of diluted net loss per share from each period as including them would have had an anti-dilutive effect. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potentially dilutive securities for each period presented:

---

| | | |
|:---|:---|:---|
| | **September 30,** | **September 30,** |
| | **2025** | **2024** |
| Options to purchase common stock | 3329979 | 3563611 |
| Restricted stock units | 4720172 | 4684455 |

**13. Commitments and Contingencies**

***Contractual Obligations***

The Company has $23.9 million of non-cancelable contractual commitments as of September 30, 2025, primarily related to its operating lease agreements for both its current and former corporate headquarters in New York, NY, not including any offset for sublease income, as well as other software and support services. For those agreements with variable terms, the Company does not estimate what the total obligation may be beyond any minimum obligations. The following table represents the Company's commitments under its purchase obligations as of September 30, 2025 (in thousands):

---

| | | | |
|:---|:---|:---|:---|
| **Fiscal Year Ending December 31,** | **Lease Obligations** | **Other Obligations** | **Total Obligations** |
| 2025 (remaining) | $1369 | $301 | $1670 |
| 2026 | 5429 | 1088 | 6517 |
| 2027 | 5429 | 318 | 5747 |
| 2028 | 5429 | 41 | 5470 |
| 2029 | 4458 |  | 4458 |
| 2030 | 41 |  | 41 |
| Total | $22155 | $1748 | $23903 |

---

***Legal Proceedings***

The Company is subject to various claims and contingencies, which are in the scope of ordinary and routine litigation incidental to its business, including those related to regulation, litigation, business transactions, employee-related matters, and taxes, among others. When the Company becomes aware of a claim or potential claim, the likelihood of any loss or exposure is assessed. If it is probable that a loss will result and the amount of the loss can be reasonably estimated, the Company records a liability for the loss. The liability recorded includes probable and estimable legal costs incurred to date and future legal costs to the point in the legal matter where the Company believes a conclusion to the matter will be reached. The Company does not believe that it is party to any pending legal proceedings that are probable to have a material effect on its business, financial condition, or results of operations for the three and nine months ended September 30, 2025. If the loss is not probable or the amount of the loss cannot be reasonably estimated, the Company discloses the claim if the likelihood of a potential loss is reasonably possible. The Company recently received a $1.4 million complaint from a trustee in a third-party bankruptcy proceeding seeking recovery of amounts paid for various purchases made on the Company's platform after the commencement of the bankruptcy proceedings. This complaint is similar to hundreds of other similar cases commenced in connection with the bankruptcy proceeding, and the Company intends to defend against the trustee's claim vigorously. The Company does not believe potential losses are estimable or probable at this time.

***Indemnification***

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners, and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its Board and officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications.

***Sales and other indirect tax contingencies***

The Company conducts operations in many tax jurisdictions for which indirect taxes, such as sales, use and other indirect taxes, are assessed on its operations. Although the Company is diligent in collecting and remitting such taxes, there is uncertainty as to what constitutes sufficient presence or responsibility for a jurisdiction to levy taxes, fees, and surcharges for sales made on an e-commerce platform. The Company recognized liabilities for contingencies related to sales and indirect taxes deemed probable and estimable totaling $1.0 million and $1.1 million as of September 30, 2025 and December 31, 2024, respectively, which are included in other current liabilities in the Company's condensed consolidated balance sheets.

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

*You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements based upon current plans, expectations, and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under "Risk Factors" in our Annual Report on Form 10-K. Our historical results are not necessarily indicative of the results that may be expected for any period in the future.*

**Company Overview**

We are one of the world's leading online marketplaces for connecting design lovers with many of the best sellers and makers of vintage, antique, and contemporary furniture, home décor, jewelry, watches, art, and fashion. We believe we are a leading online marketplace for these luxury design items based on the aggregate number of listings on our online marketplace and our Gross Merchandise Value ("GMV"). Our sellers, who undergo an evaluation by our in-house experts to vet the integrity of their listings, in-depth marketing content, and custom-built technology platform create trust in our brand and facilitate high-consideration purchases of luxury design items online. By disrupting the way these items are bought and sold, we are both expanding access to, and growing the market for, luxury design.

1stDibs began over two decades ago with the vision of bringing the magic of the Paris flea market online by creating a listings site for top vintage and antique furniture sellers. The quality of our initial seller base enabled us to build a reputation in the design industry as a trusted source for unique luxury design. Since then, we have strengthened our brand as well as deepened and broadened our seller relationships. We launched our e-commerce platform in 2013 and transitioned to a full e-commerce marketplace model in 2016.

**Key Operating and Financial Metrics**

We use the following key metrics and non-GAAP measures to evaluate our performance, identify trends affecting our business, and make strategic decisions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• GMV;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Number of Orders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Active Buyers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA (see "Non-GAAP Financial Measures" for a discussion of Adjusted EBITDA and a reconciliation of net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA).

For GMV, Number of Orders, and Active Buyers, these metrics are based on internal company data, assumptions, and estimates and are used in managing our business. We believe that these figures are reasonable estimates, and we actively take measures to improve their accuracy, such as eliminating known fictitious or duplicate accounts. There are, however, inherent challenges in gathering accurate data across large online and mobile populations. For example, individuals may have multiple email accounts in violation of our terms of service, which would result in an Active Buyer being counted more than once, thus impacting the accuracy of our number of Active Buyers. In addition, certain metrics, such as the number of Active Buyers, Number of Orders, and GMV are measured based on such numbers as reported in a given month, minus cancellations within that month. As we do not retroactively adjust such numbers for cancellations occurring after the month, the metrics presented do not reflect subsequent order cancellations. We regularly review and may adjust our processes for calculating these metrics to improve their accuracy. These key operating and financial metrics may vary from period to period and should not be viewed as indicative of other metrics.

------

***Gross Merchandise Value***

We define GMV as the total dollar value from items sold by our sellers through 1stDibs in a given month, minus cancellations within that month, and excluding shipping and U.S. sales taxes. GMV includes all sales reported to us by our sellers, whether transacted through the 1stDibs online marketplace or reported as an offline sale. We view GMV as a measure of the total economic activity generated by our online marketplace and as an indicator of the scale, growth, and health of our online marketplace. Our historical performance for GMV may not be indicative of future performance in GMV.

***Number of Orders***

We define Number of Orders as the total number of orders placed or reported through the 1stDibs online marketplace in a given month, minus cancellations within that month. Our historical performance for Number of Orders may not be indicative of future performance in Number of Orders.

***Active Buyers***

We define Active Buyers as buyers who have made at least one purchase through our online marketplace during the 12 months ended on the last day of the period presented, net of cancellations. A buyer is identified by a unique email address; thus an Active Buyer could have more than one account if they were to use a separate unique email address to set up each account. We believe this metric reflects scale, engagement and brand awareness, and our ability to convert user activity on our online marketplace into transactions. Our historical performance for Active Buyers may not be indicative of future performance in Active Buyers.

***Adjusted EBITDA***

We define Adjusted EBITDA as net loss excluding depreciation and amortization, stock-based compensation expense, other income, net, provision for income taxes, restructuring expenses and strategic alternative expenses. Adjusted EBITDA is a key performance measure used by our management and board of directors to assess our operating performance and the operating leverage of our business. We believe that Adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of the income and expenses that we exclude from Adjusted EBITDA. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results, enhances the overall understanding of our past performance and future prospects, and allows for greater transparency with respect to key financial metrics used by our management in their financial and operational decision-making. See "Non-GAAP Financial Measures" for more information and for a reconciliation of net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA.

**Components of Results of Operations**

***Net Revenue***

Our net revenue consists principally of seller marketplace services. Seller marketplace services primarily consist of marketplace transactions, subscriptions, and listing fees. Marketplace transaction fees are collected when sellers pay us commissions ranging from 5% to 50% of GMV and processing fees, which are approximately 3% of the buyer's total payment, net of expected refunds. If a seller accepts a return or refund for an on-platform purchase, the related commission and, in some cases, processing fees are refunded. Subscriptions provide access to our online marketplace, allowing sellers, who are our customers, to execute successful purchase transactions with buyers. We offer our sellers various subscription pricing tiers which allows them to choose the plan that best fits their business, with choices of a higher monthly subscription fee and lower commission rates or lower monthly subscription fee and higher commission rates. Listing fee revenue is collected when sellers pay us for promoting certain products on their behalf and at their discretion through our online marketplace. Advertisements consist of impression-based ads displayed on our online marketplace on the seller's behalf.

***Cost of Revenue***

Cost of revenue includes payment processor fees and hosting expenses. Cost of revenue also includes payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with personnel supporting revenue-related operations and logistics, consulting costs, and amortization expense related to our capitalized internal-use software.

In certain transactions where our shipping services are elected by sellers, we facilitate shipping of items purchased from the seller to the buyer. The difference between the amount collected for shipping and the amount charged by the shipping carrier is included in cost of revenue in our condensed consolidated statements of operations. We facilitate fulfillment and shipping, but do not take ownership of or manage inventory.

***Gross Profit and Gross Margin***

Gross profit is net revenue less cost of revenue, and gross margin is gross profit as a percentage of net revenue. Gross profit has been, and will continue to be, affected by various factors, including leveraging economies of scale, the costs associated with

------

hosting our platform, the level of amortization of our internal-use software, the fluctuations in shipping costs including our ability to pass these costs on to buyers, and the extent to which we expand our operations. We expect that our gross margin will fluctuate from period to period depending on the interplay of these various factors.

***Sales and Marketing***

Sales and marketing expenses include payroll, employee benefits, stock-based compensation, other headcount-related expenses associated with sales and marketing personnel, advertising expense, consulting costs, and promotional discounts offered to new and existing buyers. Advertising expenses consist primarily of costs incurred promoting and marketing our services, such as costs associated with acquiring new users through performance-based marketing, social media programs, email, and events. Promotional discounts and incentives represent incentives solely to buyers and, therefore, are not considered payments made to our customers. Buyers are not our customers because access to the 1stDibs online marketplace is free for buyers, and we have no performance obligations with respect to buyers; we consider our sellers to be our customers.

***Technology Development***

Technology development expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with engineering and product development personnel and consulting costs related to technology development. We expense all technology development expenses as incurred, except for those expenses that meet the criteria for capitalization as internal-use software.

***General and Administrative***

General and administrative expenses include payroll, employee benefits, stock-based compensation, and other headcount-related expenses associated with finance, legal, facility and human resources related personnel, lease expense, net of sublease income, business liability insurance, accounting, professional fees, consulting costs, and depreciation of property and equipment. We expense all general and administrative expenses as incurred.

***Provision for Transaction Losses***

Provision for transaction losses primarily consists of transaction loss expense associated with our buyer protection program, including damages to products caused in shipping and transit, items that were not received or not as described by the seller, and reimbursements to buyers at our discretion if they are dissatisfied with their experience. The provision for transaction losses also includes bad debt expense associated with our seller accounts receivable balance.

| Net revenue | $21972 | $21190 | $782 | 4% |

---

------

Net revenue was $22.0 million for the three months ended September 30, 2025, as compared to $21.2 million for the three months ended September 30, 2024. The increase of $0.8 million, or 4%, was primarily driven by an increase in GMV which was mainly due to an increase in average order value for the three months ended September 30, 2025. While the impacts are difficult to isolate and quantify, we believe our GMV, number of orders, and net revenue have continued to be impacted negatively, both directly and indirectly, by macroeconomic factors, including significant housing market volatility, significant capital market volatility, and global economic and geopolitical developments. We believe we have, and continue to work to position the business to benefit from an improvement in macroeconomic factors.

Our marketplace transaction fees represent the majority of our net revenue and accounted for 74% of our net revenue for each of the three months ended September 30, 2025 and 2024. Subscription fees accounted for 21% and 22% of our net revenue for the three months ended September 30, 2025 and 2024, respectively.

---

Cost of revenue was $5.6 million for the three months ended September 30, 2025, as compared to $6.2 million for the three months ended September 30, 2024. The decrease of $0.5 million, or 8%, was primarily driven by a $0.3 million decrease in net shipping expenses, partially due to an insurance recovery relating to a shipping matter and a $0.1 million decrease in credit card processing fees due to better pricing negotiated with one of our main payment processors.

***Gross Profit and Gross Margin***

Gross profit was $16.3 million and gross margin was 74.3% for the three months ended September 30, 2025, as compared to gross profit of $15.0 million and gross margin of 71.0% for the three months ended September 30, 2024. The increase in gross profit and gross margin for the three months ended September 30, 2025 was primarily driven by the decrease in cost of revenue, and to a lesser extent, the increase in net revenue, as outlined above.

The decrease of $1.2 million, or 13%, was mainly due to a $1.2 million decrease in performance-based marketing and promotional campaigns. We also had $0.7 million in savings from our January 2025 reduction in workforce which was offset by the $0.8 million of severance expense due to our September 2025 reorganization.

Other income, net was $1.2 million for the three months ended September 30, 2025, as compared to $1.7 million for the three months ended September 30, 2024. The decrease of $0.5 million, or 28%, was due mainly to lower interest income driven by lower cash, cash equivalents, and short-term investments for the three months ended September 30, 2025 coupled with lower interest rates.

---

Net revenue was $66.7 million for the nine months ended September 30, 2025, as compared to $65.5 million for the nine months ended September 30, 2024. The increase of $1.2 million, or 2%, was primarily driven by an increase in GMV which was mainly due to an increase in average order value.

Our marketplace transaction fees represent the majority of our net revenue and accounted for 74% of our net revenue for each of the nine months ended September 30, 2025 and 2024. Subscription fees accounted for 21% and 22% of our net revenue for the nine months ended September 30, 2025 and 2024, respectively.

---

Cost of revenue was $18.1 million for the nine months ended September 30, 2025, as compared to $18.5 million for the nine months ended September 30, 2024, The decrease of $0.4 million, or 2%, was primarily driven by a $0.5 million decrease in credit card processing fees due to better pricing negotiated with one of our main payment processors, partially offset by a $0.3 million increase in salaries and benefits due to annual compensation increases in March.

***Gross Profit and Gross Margin***

Gross profit was $48.6 million and gross margin was 72.8% for the nine months ended September 30, 2025, as compared to gross profit of $47.0 million and gross margin of 71.7% for the nine months ended September 30, 2024. The increase in gross profit and gross margin for the nine months ended September 30, 2025 was primarily driven by the decrease in cost of revenue and increase in net revenue as outlined above.

---

Sales and marketing expense was $25.2 million for the nine months ended September 30, 2025, as compared to $27.6 million for the nine months ended September 30, 2024. The decrease of $2.4 million, or 9%, was mainly due to a $1.5 million decrease in performance-based marketing and promotional campaigns, and a $0.8 million decrease in salaries, benefits, and stock-based compensation resulting from decreases in headcount primarily related to our reduction in workforce in January 2025. The decrease in salaries and benefits were partially offset by the severance expense related to our September 2025 reorganization.

**Non-GAAP Financial Measures**

We have included Adjusted EBITDA, which is a non-GAAP financial measure, because it is a key measure used by our management team to help us to assess our operating performance and the operating leverage in our business. We also use this measure to analyze our financial results, establish budgets and operational goals for managing our business, and make strategic decisions. We believe that Adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of the income and expenses that we exclude from Adjusted EBITDA. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations, enhances the overall understanding of our past performance and future prospects, and allows for greater transparency with respect to key financial metrics used by our management in their financial and operational decision-making. We also believe that the presentation of this non-GAAP financial measure provides an additional tool for investors to use in comparing our core business and results of operations over multiple periods with other companies in our industry, many of which present similar non-GAAP financial measures to investors, and to analyze our operating performance.

The non-GAAP financial measures presented may not be comparable to similarly titled measures reported by other companies due to differences in the way that these measures are calculated. The non-GAAP financial measures presented should not be considered as the sole measure of our performance and should not be considered in isolation from, or as a substitute for, comparable financial measures calculated in accordance with GAAP. Further, these non-GAAP financial measures have certain limitations in that they do not include the impact of certain expenses that are reflected in our condensed consolidated statements of operations. Accordingly, these non-GAAP financial measures should be considered as supplemental in nature, and are not intended, and should not be construed, as a substitute for the related financial information calculated in accordance with GAAP. These limitations of Adjusted EBITDA include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exclusion of certain recurring, non-cash charges, such as depreciation and amortization of property and equipment. While these are non-cash charges, we may need to replace the assets being depreciated in the future and Adjusted EBITDA does not reflect cash requirements for these replacements or new capital expenditure requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exclusion of stock-based compensation expense, which has been a significant recurring expense and will continue to constitute a significant recurring expense for the foreseeable future, as equity awards are expected to continue to be an important component of our compensation strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exclusion of other income, net, which includes interest income related to our cash, cash equivalents and short-term investments and realized and unrealized gains and losses on foreign currency exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exclusion of discrete restructuring expenses such as severance and benefit costs from reductions in force and reorganizations that are fundamentally different in strategic nature from ongoing initiatives. We believe the exclusion of these items facilitates a more consistent comparison of operating performance over time because they are distinct from ongoing operational costs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exclusion of strategic alternative expenses in connection with capital return strategies, buy and sell-side mergers, acquisitions, partnerships and divestitures, including integration costs.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net loss and our other GAAP results.

We define Adjusted EBITDA as our net loss, excluding: (1) depreciation and amortization; (2) stock-based compensation expense; (3) other income, net; (4) provision for income taxes; (5) restructuring expenses; and (6) strategic alternative expenses. The following table provides a reconciliation of net loss, the most directly comparable GAAP financial measure, to Adjusted EBITDA:

**Liquidity and Capital Resources**

As of September 30, 2025, we had cash, cash equivalents and short-term investments of $93.4 million and an accumulated deficit of $345.0 million. Net cash used in operating activities was $6.7 million in the nine months ended September 30, 2025. We expect operating losses to continue in the foreseeable future as we continue to strategically invest in growth activities. Our cash flows, including net cash used in or provided by operating activities, may vary from quarter to quarter, due to the timing of payments to sellers, vendor contracts and prepayments, annual bonuses, marketing related expenses, and other factors. Our principal use of cash is to fund our operations including platform development to support our strategic initiatives and anticipated share repurchases under our Stock Repurchase Programs.

Based on our current plans, we believe our existing cash, cash equivalents and short-term investments will be sufficient to fund our operations and capital expenditure requirements through at least the next 12 months. We expect to continue to incur substantial expenditures in the near term to support our ongoing activities. While management believes that our current cash, cash equivalents and short-term investments are sufficient to fund our operating expenses and capital expenditure requirements for at least the next 12 months, we may need to borrow funds or raise additional equity to achieve our longer-term business objectives.

Our future capital requirements will depend on many factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the emergence of competing online marketplaces and other adverse market developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing and extent of our sales and marketing and technology development expenditures; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any investments, acquisitions or other similar strategic endeavors we may choose to pursue in the future.

A change in the outcome of any of these or other variables could significantly impact our operating plans, and we may need additional funds to meet operational needs and capital requirements associated with such plans. In addition, any future borrowings may result in additional restrictions on our business and any issuance of additional equity would result in dilution to investors. If we are unable to raise additional capital when we need it, it could harm our business, results of operations, and financial condition.

**Stock Repurchase Program**

In August 2023, the Board of Directors authorized the 2023 Stock Repurchase Program to repurchase up to an aggregate of $20.0 million of our common stock. In June 2024, the Board of Directors authorized an increase to our 2023 Stock Repurchase Program to an aggregate authorized repurchase amount of $25.5 million. On June 10, 2024, we announced the completion of our 2023 Stock Repurchase Program.

In August 2024, the Board of Directors authorized the 2024 Stock Repurchase Program to repurchase up to an aggregate of $10.0 million of our common stock.

During the nine months ended September 30, 2025, 477,992 shares of our common stock were purchased for a total cost of $1.8 million and approximately $2.0 million remains available under our 2024 Stock Repurchase Program.

Subsequent to September 30, 2025, in November 2025, our Board of Directors authorized us to repurchase up to an aggregate of $12.0 million of our common stock ("2025 Stock Repurchase Program"). The Board also terminated the 2024 Stock Repurchase Program it previously authorized in August 2024.

*Cash Flows from Operating Activities*

Net cash used in operating activities was $6.7 million for the nine months ended September 30, 2025 and was due mainly to changes in operating assets and liabilities, including a $3.1 million decrease in operating lease liabilities due to our operating lease payments, a $1.8 million increase in prepaid expenses and other current assets due to timing of prepaid contracts, a $1.5 million decrease in payables due to sellers as a result of timing of when sellers are paid, and a $1.1 million decrease in accounts payable and accrued expenses due to the timing of vendor invoices and related invoices.

Net cash used in operating activities was $5.7 million for the nine months ended September 30, 2024, and was driven primarily by a $2.2 million decrease in accounts payable and accrued expenses due to the timing of payments and invoices, a $2.2 million decrease in operating lease liabilities due to the continued lease payments on our previous and current NYC headquarters, partially offset by our sublease income, and a $1.8 million decrease in other current liabilities and other liabilities related to payments to settle multiple Sales and other non-income tax contingencies. Theses decreases were partially offset by a $2.7 million increase in payables due to sellers due to timing of the bi-weekly payments we make to our sellers.

*Cash Flows from Investing Activities*

Net cash provided by investing activities was $4.2 million for the nine months ended September 30, 2025, and was mainly due to by $56.8 million in maturities and sales of short-term investments, partially offset by $51.9 million in purchases of short-term investments.

Net cash provided by investing activities was $15.3 million for the nine months ended September 30, 2024, and was driven primarily by $85.6 million maturities and sales of short-term investments, partially offset by $68.9 million purchases of short-term investments.

*Cash Flows from Financing Activities*

Net cash used in financing activities was $3.8 million for the nine months ended September 30, 2025, and was driven primarily by $2.0 million of payments for taxes related to net share settlements of stock-based compensation awards and $1.8 million in repurchases of our common stock as part of our 2024 Stock Repurchase Program.

Net cash used in financing activities was $25.2 million for the nine months ended September 30, 2024, and was driven primarily by $22.8 million in repurchases of our common stock as part of our 2023 and 2024 Stock Repurchase Programs and $3.2 million of payments for taxes related to net share settlements of stock-based compensation awards, partially offset by $0.8 million in proceeds from the exercise of stock options.

**Interim Goodwill Impairment Assessment**

During the three months ended September 30, 2025, the Company performed a quantitative assessment of our goodwill as a result of the continued decline in our stock price and related overall market capitalization, as well as the impact of macroeconomic factors. While there was no impairment recorded, the fair value of our reporting unit, without the use of an implied control premium, exceeded its carrying value by less than 10%, indicating that goodwill may be at risk of impairment in the future.

**Contractual Obligations**

As of September 30, 2025, there were no material changes in commitments under contractual obligations compared to the contractual obligations disclosed in our Form 10-K.

------

**Recent Accounting Pronouncements**

See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies" to our condensed consolidated financial statements for a description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations, or cash flows.

**Emerging Growth Company**

We are an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that (i) we are no longer an emerging growth company or (ii) we affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

**Critical Accounting Policies and Estimates**

Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

There have been no significant changes to our critical accounting policies and estimates included in our Form 10-K.

**Item 3. Quantitative and Qualitative Disclosures about Market Risk**

We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our business, including the effects of interest rate changes and foreign currency fluctuations. Information relating to quantitative and qualitative disclosures about these market risks are described below. At times, our cash balances with individual banking institutions are in excess of federally insured limits. We have not experienced any credit losses related to our cash, cash equivalents, and short-term investments balances.

***Interest Rate Sensitivity***

Interest rate risk relates to the loss we could incur in our cash, cash equivalents and short-term investments due to a change in interest rates. As of September 30, 2025, we had cash, cash equivalents and short-term investments of $93.4 million. Our cash and cash equivalents consist primarily of demand, money market accounts, and available-for-sale debt securities with an original maturity of 90 days or less. Our short-term investments consist primarily of U.S. Government agency and Treasury securities, as well as commercial paper and corporate notes which have an original maturity greater than 90 days and are highly liquid in nature. Due to the nature of our cash, cash equivalents and short-term investments, we would expect a hypothetical 100 basis point increase or decrease in interest rates to result in an approximate increase or decrease of $0.7 million in our cash, cash equivalents and short-term investments. While these are our best estimates of the impact of the specified interest rate scenario, actual results could differ from those projected. The sensitivity analysis presented assumes interest rate changes and parallel shifts in the yield curve are instantaneous. In reality, interest rate changes of this magnitude are rarely instantaneous or parallel.

Our principal use of cash, cash equivalents and short-term investments is to fund our operations including platform development to support our strategic initiatives and anticipated share repurchases under our Stock Repurchase Programs. The remainder of cash, cash equivalents and short-term investments are held for working capital purposes and other potential uses including strategic investment opportunities. We do not enter into investments for trading or speculative purposes.

***Foreign Currency Risk***

Our net revenue is primarily denominated in U.S. dollars, Euros, and British pounds, depending on the currency selection of the seller. Our cost of revenue and operating expenses are primarily denominated in U.S. dollars. As our online marketplace continues to grow globally, our results of operations and cash flows may be subject to fluctuations due to the change in foreign exchange rates. To date, fluctuations due to changes in the Euro and the British pound have not been significant, but we may experience material foreign exchange gains and losses in our statement of operations in the future. As of September 30, 2025, we would expect an adverse 10% change in current exchange rates to result in no more than a $2.4 million decrease in net revenue for the nine months ended September 30, 2025.

------

***Credit Risk***

We are exposed to credit risk on accounts receivable balances. This risk is mitigated by requiring upfront payment for many of our services due to our diverse seller base, dispersed over various geographic regions and industry sectors. For the three and nine months ended September 30, 2025 and 2024, no single customer accounted for more than 10% of our net revenue. We maintain provisions for potential credit losses and such losses to date have been within our expectations. We evaluate the solvency of our customers on an ongoing basis to determine if additional allowances for doubtful accounts need to be recorded.

***Inflation Risk***

Our results of operations and financial condition are presented based on historical cost. While it is difficult to accurately measure the impact of inflation due to the imprecise nature of the estimates required, we believe certain metrics have continued to be impacted negatively, both directly and indirectly, by macroeconomic factors, including significant housing market volatility, significant capital market volatility, and global economic and geopolitical developments. Additionally, if our costs were to become subject to inflationary pressures, we might not be able to fully offset such higher costs through net revenue and GMV increases. Our inability or failure to do so could harm our business, financial condition, and results of operations. We cannot assure you that our business will not be affected in the future by inflation.

**Item 4. Controls and Procedures**

***Evaluation of Disclosure Controls and Procedures***

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2025. "Disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended ("Exchange Act"), are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2025 at the reasonable assurance level.

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

***Changes in Internal Control over Financial Reporting***

There were no changes in our internal control over financial reporting identified during the three months ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

***Inherent Limitations on Effectiveness of Controls***

Our management, including our Chief Executive Officer and our Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting 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 a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by the collusion of two or more people or by management override of controls. The design of any system of controls is also based in part upon 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; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

------

**Part II - Other Information**

**Item 1. Legal Proceedings**

From time to time, we are involved in legal proceedings and subject to claims arising both inside and outside the ordinary course of business. The Company recently received a $1.4 million complaint from a trustee in a third-party bankruptcy proceeding seeking recovery of amounts paid for various purchases made on the Company's platform after the commencement of the bankruptcy proceedings. This complaint is similar to hundreds of other similar cases commenced in connection with the bankruptcy proceeding, and we intend to defend against the trustee's claim vigorously. The results of this claim, and other litigation and claims in the ordinary course, cannot be predicted with certainty, and the Company does not believe potential losses are estimable or probable at this time. Even if any particular litigation or claim is not resolved in a manner that is adverse to our interests, such litigation can have a negative impact on us because of defense and settlement costs, diversion of management resources from our business, and other factors.

**Item 1A. Risk Factors**

We operate in a rapidly changing environment that involves a number of risks that could materially and adversely affect our business, financial condition, prospects, operating results or cash flows. For a detailed discussion of certain risks that affect our business, refer to the section entitled "Risk Factors" in our 2024 Annual Report on Form 10-K. There have been no material changes to the risk factors disclosed in our 2024 Form 10-K.

The risks described in our 2024 Form 10-K are not the only risks we face. We describe in Management's Discussion and Analysis of Financial Condition and Results of Operations in Part I of this Quarterly Report on Form 10-Q certain known trends and uncertainties that affect our business. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, operating results and financial condition.

**Item 2. Unregistered Sales of Equity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities**

None.

**Item 5. Other Information**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c) Adoption or Termination of Insider Trading Arrangements**
