CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended ("Exchange Act"). All statements in this report other than historical facts are forward-looking and are based on current estimates, assumptions, trends, and projections. Statements which include the words "believes," "seeks," "expects," "may," "should," "intends," "likely," "targets," "plans," "anticipates," "estimates," or the negative version of those words and similar expressions are intended to identify forward-looking statements. Numerous important factors, risks and uncertainties affect our operating results, including, without limitation, those described in our Annual Report on Form 10-K and in this Quarterly Report on Form 10-Q, and could cause our actual results to differ materially, from the results implied by these or any other forward-looking statements made by us or on our behalf. You should pay particular attention to the important risk factors and cautionary statements described in the section of our Annual Report on Form 10-K entitled "Risk Factors" and the section of this Quarterly Report on Form 10-Q entitled "Risk Factors." You should also carefully review the cautionary statements described in the other documents we file with the Securities and Exchange Commission, specifically the Annual Report on Form 10-K, all Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
You should not rely on forward-looking statements as predictions of future events, as we cannot guarantee that future results, levels of activity, performance or achievements will meet expectations. The forward-looking statements made herein are only made as of the date hereof, and we undertake no obligation to publicly update such forward-looking statements for any reason.

Certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with GAAP have been omitted from these interim unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 ("Annual Report") filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2023 was derived from the Company's audited consolidated financial statements but does not include all disclosures required under GAAP.

Deferred costs
Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are deferred and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. The Company determined the period of benefit by taking into consideration its customer contracts, expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for renewals), the Company's technology and other factors. The Company also defers amounts earned by employees other than sales representatives who earn incentive payments under compensation plans also tied to the value of customer contracts acquired. Deferred costs were $14.6 million and $15.1 million as of June 30, 2024 and December 31, 2023, respectively. Amortization expense for the deferred costs was $1.1 million and $1.5 million for the three months ended June 30, 2024 and 2023, respectively, and $2.4 million and $2.9 million for the six months ended June 30, 2024 and 2023, respectively. Amortization of deferred costs is included in selling and marketing expense in the accompanying unaudited condensed consolidated statements of comprehensive loss.

Dilutive potential common shares consist of shares issuable upon the vesting of restricted stock units ("RSUs") and market stock units ("MSUs"). Potential common shares determined to be antidilutive and excluded from diluted weighted average shares outstanding were approximately 1.9 million and 1.7 million for the three months ended June 30, 2024 and 2023, respectively, and 1.4 million and 1.7 million for the six months ended June 30, 2024 and 2023, respectively. In addition, potential common shares related to the convertible notes determined to be antidilutive and excluded from diluted weighted average shares outstanding were 6.5 million and 6.6 million for the three and six months ended June 30, 2024, respectively, and 5.8 million for the three and six months ended June 30, 2023.
7. Noncash Share-based Compensation
The Company's 2017 Equity Incentive Plan (as amended and restated, the "2017 Stock Plan") had an aggregate authorized limit of 7,650,000 shares for issuance. In May 2023, the Company's stockholders approved an amendment to the 2017 Stock Plan increasing the aggregate amount of shares available for issuance to 10,550,000. As of June 30, 2024, 3,254,841 shares remain available for issuance under the 2017 Stock Plan.
The following table presents the number of shares or units outstanding for each award type as of June 30, 2024 and December 31, 2023 (in thousands):

Award type |  | June 30, 2024 |  | December 31, 2023
Restricted stock units (time-based) |  | 2,969 |  |  | 2,767 |
Market stock units |  | 439 |  |  | 358 |

During the three months ended June 30, 2024, the Company granted 137,531 RS Us (time-based) with a weighted average grant-date fair value of $32.43 per share. During the six months ended June 30, 2024, the Company granted 1,333,618 RSUs (time-based) with a weighted average grant-date fair value of $35.35 per share.
The Company also granted 47,789 MSUs with a weighted average grant-date fair value of $36.87 to certain executive employees during the three months ended June 30, 2024, and 179,681 MSUs with a weighted average grant-date fair value of $39.95 to certain executive employees during the six months ended June 30, 2024. These MSUs vest on January 31, 2027, and the actual number of MSUs that will be eligible to vest is based on the total stockholder return of the Company relative to the total stockholder return of the Index over the performance period, as defined by each award's plan documents or individual award agreements. The maximum number of shares issuable upon vesting is 200% of the MSUs initially granted.
The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The weighted average assumptions used to value the MSUs granted during the three and six months ended June 30, 2024 were as follows:

At June 30, 2024, the Company had an estimated $91.6 million of total unrecognized compensation costs related to share-based compensation arrangements. These costs will be recognized over a weighted average period o f 2.8 years.
The Company's Employee Stock Purchase Plan (as amended, the "ESPP") permits eligible employees to purchase Company shares on an after-tax basis in an amount between 1% and 10% of their annual pay: (i) on June 30 of each year at a 15% discount of the fair market value of the Company's common stock on January 1 or June 30, whichever is lower, and (ii) on Dec ember 31 of each year at a 15% discount of the fair market value of the Company's common stock on July 1 or December 31, whichever is lower. An employee may not purchase more than $5,000 in either of the six-month measurement periods described above or more than $10,000 annually. In May 2021, the Company's stockholders approved an amendment to the ESPP increasing the aggregate amount of shares available for issuance under the ESPP to 1,000,000. During the three and six months ended June 30, 2024, the Company issued zero and 40,408 shares under the ESPP, respectively. As of June 30, 2024, 242,709 shares remain authorized and available for issuance under the ESPP. As of June 30, 2024, the Company held approximately $1.1 million on behalf of employees for future purchases under the ESPP, and this amount was recorded in accrued payroll and other employee benefits in the Company's unaudited condensed consolidated balance sheet.
8. Convertible Senior Notes
The following is a summary of the Company's convertible senior notes as of June 30, 2024 (in thousands):

| Date of Issuance |  | Unpaid Principal Balance |  |  |  | Contractual Interest Rates
1% Convertible Notes due in 2024 ("2024 Notes") | May 2019 |  | $ | — |  |  |  |  |  |  | 1%
2.25% Convertible Notes due in 2027 ("2027 Notes") | September 2020 and October 2023 |  | $ | 266,816 |  |  |  |  |  |  | 2.25%
Total Notes |  |  | $ | 266,816 |  |  |  |  |  |  |

The 2027 and 2024 Notes (collectively, the "Notes") are general unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated, are effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries (including trade payables but excluding intercompany obligations owed to the Company or its subsidiaries).

Table of Contents
The 2027 Notes mature on September 15, 2027, unless redeemed or converted in accordance with their terms prior to such date. The 2024 Notes matured on May 15, 2024 and the Company settled the outstanding principal balance of $21.7 million during the quarter ended June 30, 2024.
Interest related to the 2027 Notes is payable semi-annually in arrears in cash on March 15 and September 15 of each year, beginning on March 15, 2021. Interest related to the 2024 Notes was payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2019.
Each $1,000 of principal of the 2027 Notes will initially be convertible into 23.9137 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $41.82 per share and is subject to adjustment upon the occurrence of certain specified events. Each $1,000 of principal of the 2024 Notes was initially to be convertible into 15.1394 shares of the Company’s common stock, which was equivalent to an initial conversion price of approximately $66.05 per share and was subject to adjustment upon the occurrence of certain specified events.
On August 23, 2023, the Company entered into legally binding exchange agreements with a limited number of existing holders of the 2024 Notes to exchange approximately $122.0 million aggregate principal amount of the existing 2024 Notes for a principal amount of the 2027 Notes at an exchange ratio to be determined based on the daily volume-weighted average trading price of the Company’s common stock over a thirty-day trading period beginning August 24, 2023 (such exchange transactions, the “Exchange”). On October 10, 2023, the Company settled the exchange agreements for the exchange of $122.0 million aggregate principal amount of its outstanding 2024 Notes for newly issued $116.8 million aggregate principal amount of its outstanding 2027 Notes. Following the settlement of the Exchange, $21.7 million in aggregate principal amount of the 2024 Notes and $266.8 million in aggregate principal amount of the 2027 Notes remained outstanding with terms unchanged. The 2027 Notes issued in the Exchange constitute a further issuance of, and form a single series and will be fungible with, the existing 2027 Notes.
As of June 30, 2024, the 2027 Notes are not yet convertible and their remaining term is approximatel y 39 months.
As of June 30, 2024 and December 31, 2023, the fair value of the outstanding principal amount of the Notes in the aggregate was $256.7 million and $320.5 million, respectively. The estimated fair value was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the Company's stock price and interest rates, which represents level 2 in the fair value hierarchy.
The Notes consist of the following (in thousands):

| June 30, 2024 |  | December 31, 2023
Principal | $ | 266,816 |  |  | $ | 288,529 |
Debt premium, net of amortization | 8,427 |  |  | 9,776 |
Debt issuance costs, net of amortization | (3,690) |  |  | (4,313) |

Capped call transactions
In September 2020 and in May 2019, in connection with the offering of the 2027 and 2024 Notes, respectively, the Company entered into privately negotiated capped call transactions (collectively, the "Capped Call") with certain option counterparties. The Capped Call transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the Notes, at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The Capped Call transactions are intended
14

Table of Contents
to reduce potential dilution to the Company’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amounts upon any conversion of the Notes, and to effectively increase the overall conversion price of the 2027 Notes from $41.82 to $78.90 per share, and for the 2024 Notes from $66.05 to $101.62 per share. As the Capped Call transactions meet certain accounting criteria, they are recorded in stockholders’ (deficit) equity and are not accounted for as derivatives. The cost of the Capped Call was $25.3 million and $16.4 million for the 2027 and 2024 Notes, respectively, and was recorded as part of additional paid-in capital. On May 15, 2024, the 2024 Notes matured and the Capped Call associated with the 2024 Notes expired unexercised. The expiration of the 2024 Notes Capped Call did not have an impact on the unaudited condensed consolidated financial statements.
In August 2023, in connection with the Exchange, the Company entered into additional capped call transactions (the “Additional Capped Call”) with certain option counterparties. The Company agreed to pay a premium to the option counterparties for the Additional Capped Call for an amount to be determined based on the volume-weighted average trading price of the Company’s common stock over a thirty-day reference period beginning August 24, 2023. The conversion price of the Additional Capped Call is the same as the 2027 Notes Capped Call above. Initial funding of the Additional Capped Call occurred in the third quarter of 2023. The Additional Capped Call had a deferred premium component indexed to the Company's stock price and required to be settled in cash, and therefore the Additional Capped Call was a derivative instrument that, at inception, did not meet the qualifications for equity classification. On October 10, 2023, the Company settled the deferred premium on the Additional Capped Call resulting in a final value of $22.2 million. Once the deferred premium was settled, the instrument met the requirements for equity classification and the Company reclassified the Additional Capped Call to additional paid-in capital.
9. Commitments and Contingencies
Litigation
In the ordinary course of business, the Company regularly becomes involved in contract and other negotiations and, in more limited circumstances, becomes involved in legal proceedings, claims and litigation. The outcomes of these matters are inherently unpredictable. The Company is not currently involved in any outstanding litigation that it believes, individually or in the aggregate, will have a material adverse effect on its business, financial condition, results of operations or cash flows.
Purchase commitments
In the ordinary course of business, the Company enters into various purchase commitments for goods and services, mainly related to infrastructure platforms, business technology software and support, and other services. In January 2023, the Company entered into a noncancelable agreement for software support services with a four-year term. The remaining purchase commitment as of June 30, 2024 was $2.4 million and the agreement expires in March 2027. There were no other material changes outside the ordinary course of business to the noncancellable purchase commitments disclosed in the Annual Report.
10. Severance and Other Related Costs
In the first quarter of 2023, the Company made certain organizational changes and incurred approximately zero and $3.6 million of severance, employee benefits, outplacement and related costs during the three and six months ended June 30, 2023, respectively. These costs were recorded primarily as operating expenses in the unaudited condensed consolidated statements of comprehensive loss, mainly research and development, and sales and marketing. During the three and six months ended June 30, 2023, cash payments of $0.6 million and $3.7 million, respectively, were recorded for the incurred costs. The Company settled the remaining accrued expense within 2023.

The terms “we,” “us,” “PROS” and “our” refer to PROS Holdings, Inc. and all of its subsidiaries that are consolidated in conformity with generally accepted accounting principles in the United States.
This management's discussion and analysis of financial condition and results of operations should be read along with the unaudited condensed consolidated financial statements and unaudited notes to unaudited condensed consolidated financial statements included in Part I, Item 1 ("Interim Condensed Consolidated Financial Statements (Unaudited)"), as well as the audited consolidated financial statements and notes to consolidated financial statements and management's discussion and analysis of financial condition and results of operations set forth in our Annual Report.
Q2 2024 Financial Overview
In the second quarter of 2024, we continued to grow our subscription revenue, increasing subscription revenue by 14% and 15% for the three and six months ended June 30, 2024, respectively, as compared to the same periods in 2023. Total revenue increased by 8% and 9% for the three and six months ended June 30, 2024, respectively, as compared to the same periods in 2023.
For the three and six months ended June 30, 2024, recurring revenue (which consists of subscription revenue and maintenance and support revenue) accounted for 84% of total revenue. Our gross revenue retention rates remained above 93% during the twelve months ended June 30, 2024.
In the second quarter of 2024, we continued to improve on our profitability metrics. Our subscription gross profit margin was 78% for the three and six months ended June 30, 2024 as compared to 75% for the three and six months ended June 30, 2023.
Cash provided by operating activities was $1.8 million for the six months ended June 30, 2024 as compared to c ash used in operating activities of $12.7 million for the six months ended June 30, 2023. The improvement was primarily due to a significant reduction in our net loss and an increase in cash collections from our customers.
Factors Affecting Our Performance
Key factors and trends that have affected, and we believe will continue to affect, our operating results include:
•Macroeconomic and Geopolitical Environment. The companies we serve continue to navigate a difficult macroeconomic and regulatory environment impacted by inflation, higher interest rates, supply chain disruptions, tight labor markets, pricing volatility, rapid new regulations, geopolitical conflicts, including the Russia-Ukraine and Middle East conflicts, and other local and regional macroeconomic conditions. Uncertain macroeconomic, regulatory and industry conditions in the geographies where we operate create a continued challenging selling environment for enterprise technology deployments, including in some cases more complex customer review and approval cycles. For example, AI regulation, such as the EU AI Act, creates uncertainty and increases scrutiny by companies adopting AI, even where the AI utilized is compliant with applicable regulations. Despite this environment, we remain confident in our ability to help our customers drive profitable growth by optimizing their shopping and selling experiences. For example, pricing volatility and inflation can be meaningful catalysts for demand for our AI-driven price optimization and management solutions. We believe in the near term that new customers will continue to emphasize smaller scope initial purchases and fast return on their investments. We believe this emphasis will require solid execution by our teams to capitalize on these demand drivers.
•Profitable Growth as a Priority. We continue to focus on profitability by investing in a disciplined manner to drive revenue growth and support our long-term initiatives. This includes investments designed to accelerate our customer time-to-value, improve efficiency and operations, further leveraging AI in our business operations, provide out-of-the-box integration with third-party commerce solutions and develop new applications and technologies. We expect our product development, sales and marketing, and general and administrative expenses as a percentage of total revenues will decrease long-term as we increase our revenues and focus on profitability.
•Artificial Intelligence. The rapidly evolving market interest in generative AI and associated interest in all aspects of AI continues to drive businesses around the world and across industries to consider, invest in and use applications

leveraging AI. For example, companies use AI to extract insights from their data, improve and customize their offerings, and drive process and operating efficiencies. Our AI-powered solutions enable buyers to move fluidly and with personalized experiences across our customers’ sales channels, and our digital offer marketing solutions help our customers drive their buyers directly into their direct selling channels. The pace of change across industries helps fuel demand for our solutions as businesses look to replace manual processes with AI. We have utilized AI in our solutions for years and our deep experience in AI continues to influence our category-leading solutions. For example, our current AI uses a neural network to leverage all available data and attributes to improve prediction accuracy. We are also utilizing and considering new ways to expand AI use in our own business operations to drive efficienci es, improve knowledge management, gain insights and increase productivity.
•Travel Industry Dynamics. The travel industry continues to recover from the unprecedented disruption caused by the pandemic with global air passenger traffic exceeding pre-pandemic levels during 2024. Demand for air travel remains strong, and the airline industry is working to reestablish equilibrium in light of aircraft delivery issues and operational, cost and supply chain challenges. There is a growing awareness amongst airlines of the importance of competing for customers based on the total travel experience, while also improving financial performance. In some cases, this includes a renewed focus on revenue management systems. We believe our other solutions are also well-positioned, particularly as airlines look to enhance their digital marketing, booking capabilities, and ancillary offerings. However, operational challenges within the airline industry continue to impact sales cycles and approval processes.
•Digital Purchasing Driving Technology Adoption. We believe the long-term trends toward digital purchasing by both consumers and corporate buyers drives demand for technology that provides fast, frictionless and personalized buying experiences across direct sales, partner, online, mobile and emerging channels. Buyers often prefer not to interact with sales representatives as their primary source of research, and to buy online when they have already decided what to buy. For example, in the airline industry, the pandemic accelerated a long-term trend towards direct booking channels, and we anticipate airlines continuing to invest in technology to enhance their ability to capture a greater percentage of bookings and provide increasingly personalized offers through their own channels such as their websites. We believe companies increasingly compete based on customer experience and must adopt technologies which power consistent offers and experiences across sales channels.

Maintenance and support revenue decreased primarily as a result of existing maintenance customers migrating to our cloud solutions and, to a lesser extent, customer maintenance churn. We expect maintenance revenue to continue to decline as we continue to migrate maintenance customers to our cloud solutions.
Services revenue. During the three months ended June 30, 2024, services revenue decreased mainly due to the completion of several large implementations during the second quarter of 2023. During the six months ended June 30, 2024, services revenue increased primarily as a result of higher sales of professional services to our existing customers. Services

revenue varies from period to period depending on different factors, including the level of professional services required to implement our solutions, which in turn can vary depending on the mix of new versus existing customer software solution sales. Services revenue is also impacted by the timing of services revenue recognition on certain subscription contracts and efficiencies in our solutions implementations requiring less professional services during a particular period.

Cost of subscription. Cost of subscription increased primarily due to higher infrastructure cost to support the growth in our current subscription customer base and higher employee-related costs primarily due to an increase in headcount. These increases were partially offset by a decrease in amortization expense for intangible assets and internal-use software expense. O ur subscription gross profit percentages were 78% for the three and six months ended June 30, 2024, and 75% for the three and six months ended June 30, 2023.
Cost of maintenance and support. Cost of maintenance and support decreased mainly due to lower personnel costs as our maintenance customer base declined primarily with migrations to our subscription solutions. Maintenance and support gross profit percentages were 48% for the three and six months ended June 30, 2024, and 63% and 62% for the three and six months ended June 30, 2023, respectively. Gross profit percentages decreased in 2024 as compared to prior year primarily due to lower maintenance and support revenue an d the cost of maintenance and support being partially fixed.
Cost of services. Cost of services remained relatively unchanged during the three months ended June 30, 2024 as compared to the three months ended June 30, 2023. The decrease during the six months ended June 30, 2024 was primarily due to prior organizational headcount changes and other allocated overhead. Services gross profit percentages were 4% and 6% for the three months ended June 30, 2024 and 2023, respectively, and 4% and (4)% for the six months ended June 30, 2024 and 2023, respectively. Services gross profit percentages improved during the first half of 2024 compared to the same period in 2023 primarily due to an increase in services revenue as well as a decrease in cost of services. Services gross profit percentages vary period to period depending on different factors, including the level of professional services required to implement our solutions, the utilization of our employees and our effective man-day rates.

Selling and marketing expenses. S elling and marketing expenses decreased primarily due to a decrease in employee-related costs. The decrease in selling and marketing expense for the six months ended June 30, 2024 also included the impact from severance cost in prior year as well as a decrease in sales and marketing events and initiatives year-over-year.
Research and development expenses. Research and development expenses remained relatively unchanged for the three months ended June 30, 2024. During the six months ended June 30, 2024, research and development expenses increased primarily due to higher employee-related expenses mainly due to higher headcount, an increase in contract labor and noncash share-based compensation expense.

Convertible debt interest and amortization. Our convertible debt expense consisted of coupon interest and amortization of debt premium and debt issuance costs attributable to our Notes. The decrease in expense was related to the exchange of approximately 85% of PROS outstanding convertible notes that were due in May 2024 for newly issued convertible notes now due in September 2027. See Note 8 for more information.
Other income, net. The decrease in other income, net for the three months ended June 30, 2024 was primarily due to a decrease in interest income as compared to the same period in 2023. During the six months ended June 30, 2024, the change in other income, net was primarily related to loss on disposal of assets associated with a lease modification in the first quarter of 2024, see Note 5 for more information. The decrease was also due to lower interest income during the period as well as the impact of foreign currency fluctuations.
Income tax provision:

Income tax provision. The tax provision for the three and six months ended June 30, 2024 included both foreign income and withholding taxes. No tax benefit was recognized on jurisdictions with a projected loss for the year due to the valuation allowances on our deferred tax assets.
Our effective tax rate was (5)% and (1)% for the three months ended June 30, 2024 and 2023, respectively, and (4)% and (1)% for the six months ended June 30, 2024 and 2023, respectively. The income tax rate varies from the 21% federal statutory rate primarily due to the valuation allowances on our deferred tax assets. While our expected tax rate would be 0% due to the full valuation allowance on our deferred tax assets, the income tax provision and related effective tax rates was due to foreign income and withholding taxes.
Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation allowances on our deferred tax assets are excluded from the estimated annual federal effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.
Liquidity and Capital Resources
At June 30, 2024, we had $139.1 million of cash and cash equivalents and $36.2 million of working capital as compared to $168.7 million of cash and cash equivalents and $37.3 million of working capital at December 31, 2023. The decrease in cash and cash equivalents was primarily related to the settlement of the outstanding principal of our 2024 Notes of $21.7 million, which matured in May 2024.
Our principal sources of liquidity are our cash and cash equivalents, cash flows generated from operations and potential borrowings under our $50 million credit agreement (the "Credit Agreement"). In addition, we could access capital markets to supplement our liquidity position. Our material drivers or variants of operating cash flow are net income (loss) and the timing of invoicing and cash collections from our customers. Our operating cash flows are also impacted by the timing of payments to our vendors and the payments of other liabilities.

Table of Contents
We believe we will have adequate liquidity and capital resources to meet our operational requirements, anticipated capital expenditures, and coupon interest of our 2027 Notes for the next twelve months. Our future working capital requirements depend on many factors, including the operations of our existing business, growth of our customer subscription services, future acquisitions we might undertake, expansion into complementary businesses, timing of adoption and implementation of our solutions and customer churn. Capital markets have tightened in response to the macroeconomic environment making new financing more difficult and/or expensive and we may not be able to obtain such financing on terms acceptable to us or at all.
The following table presents key components of our unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2024 and 2023:

| Six Months Ended June 30,
(Dollars in thousands) | 2024 |  | 2023
Net cash provided by (used in) operating activities | $ | 1,776 |  |  | $ | (12,685) |
Net cash used in investing activities | (609) |  |  | (1,823) |
Net cash used in financing activities | (30,850) |  |  | (4,531) |
Effect of foreign currency rates on cash | 22 |  |  | (21) |
Net change in cash, cash equivalents and restricted cash | $ | (29,661) |  |  | $ | (19,060) |

Operating activities
Net cash provided by operating activities for the six months ended June 30, 2024 was $1.8 million. The improvement was primarily due to a significant reduction in our net loss and an increase in cash collections from our customers.
Investing activities
Net cash used in investing activities for the six months ended June 30, 2024 was $0.6 million. The decrease was mainly due to higher capital expenditures in 2023, primarily related to a third-party software license renewal.
Financing activities
Net cash used in financing activities for the six months ended June 30, 2024 was $30.9 million. The increase year-over-year was primarily due to the $21.7 million settlement of our 2024 Notes as they matured in May 2024 and higher tax withholding payments of $4.5 million related to the vesting of employee share-based awards.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material. We do not have any relationships with unconsolidated entities or financial partnerships, such as variable interest entities, that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.
Contractual Obligations and Commitments
Other than changes described in Note 9 above and noted below, there have been no material changes to our contractual obligations and commitments disclosed in our Annual Report.
Credit facility
As of June 30, 2024, there were no outstanding borrowings under our Credit Agreement. As of June 30, 2024, $0.6 million of unamortized debt issuance costs related to the Credit Agreement is included in prepaid and other current assets and other assets, noncurrent in the unaudited condensed consolidated balance sheets. For the three and six months ended June 30, 2024, we recorded an immaterial amount of amortization of debt issuance costs which is included in other income, net in the unaudited condensed consolidated statements of comprehensive loss.

See "Recently issued accounting pronouncements not yet adopted" in Note 2 above for discussion of recent accounting pronouncements including the respective expected dates of adoption, if any.
Critical accounting policies and estimates
Our unaudited condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures. Actual results could differ from those estimates. The complexity and judgment required in our estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in determining the nature and timing of satisfaction of performance obligations and determining the standalone selling price of performance obligations, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for credit losses, operating lease right-of-use assets and operating lease liabilities, useful lives of assets, depreciation, income taxes and deferred tax asset valuation, valuation of stock awards, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. Our critical accounting policies related to the estimates and judgments are discussed in our Annual Report under management's discussion and analysis of financial condition and results of operations.

PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
From time to time, we are a party to legal proceedings and claims arising in the ordinary course of business. We are not currently aware of any such proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition, results of operations or cash flows.
ITEM 1A. RISK FACTORS
Except as set forth below, there have been no material changes in the Company's risk factors from those disclosed in Part I, Item 1A, of our Annual Report.
We depend on third-party data centers, software, data and other unrelated service providers and any disruption from such third-party providers could impair the delivery of our service and negatively affect our business.
Our cloud products are dependent upon third-party hardware, software and cloud hosting vendors, including Microsoft Azure, IBM Softlayer and AWS, all of which must interoperate for end users to achieve their computing goals. We utilize third-party data center hosting facilities, cloud platform providers and other service providers to host and deliver our subscription services as well as for our own business operations. We host our cloud products from data centers in a variety of countries. While we control and generally have exclusive access to our servers and all of the components of our network that are located in our external data centers, we do not control the operation of these facilities and they are vulnerable to damage or interruption from hurricanes, earthquakes, floods, fires, power loss, telecommunications and human failures and similar events. They may also be subject to Security Incidents, break-ins, sabotage, intentional acts of vandalism and similar misconduct. Despite our failover capabilities, standard protocols and other precautions, the occurrence of a natural disaster or an act of terrorism, a decision to close the facilities without adequate notice or other unanticipated problems at these facilities could result in lengthy interruptions in our service. In addition, disruptions to the supply chain necessary to maintain these third-party systems or to run our business could impact our service availability and performance. These providers have no obligation to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew these agreements on commercially reasonable terms or at all, or if one of our data center operators is acquired, we may be required to transfer our servers and other infrastructure to new data center facilities, and we may incur significant costs and possible service interruption in connection with doing so.
Certain of our applications are essential to our customers’ ability to quote, price, and/or sell their products and services. Interruption in our service may affect the availability, accuracy or timeliness of quotes, pricing or other information and could require us to issue service credits to our customers, damage our reputation, cause our customers to terminate their use of our solutions, require us to indemnify our customers against certain losses, and prevent us from gaining additional business from current or future customers. In addition, certain of our applications require access to our customers' data which may be held by third parties, some of whom are, or may become, our competitors. For example, many of our travel industry products rely upon access to airline data held by large airline IT providers which compete against certain of our airline products. Certain of these competitors have in the past, and may again in the future, make it difficult for our airline customers to access their data in a timely and/or cost-effective manner.
We have experienced, and may experience in the future, system disruptions, outages and other performance problems due to third-party data centers, software, data and other service providers, many of which are shared by other SaaS providers. These disruptions could impair the delivery of our service and negatively affect our business, damage our reputation, negatively impact our future sales and/or cash flows and lead to legal liability and other costs, and the full impact of which may not be immediately known.
