NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. GENERAL

We have prepared the accompanying unaudited condensed consolidated financial statements as of March 31, 2024 and December 31, 2023, and for the quarters ended March 31, 2024 and 2023, in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) for interim financial information, and pursuant to the instructions to Form 10-Q and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of our management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of our financial position and operating results have been included. The unaudited Condensed Consolidated Financial Statements (the “Financial Statements”) should be read in conjunction with the Consolidated Financial Statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), contained in our Annual Report on Form 10-K for the year ended December 31, 2023 (our “2023 10-K”), filed with the SEC. The results of operations for the quarter ended March 31, 2024 are not necessarily indicative of the expected results for the entire year ending December 31, 2024.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates in Preparation of Financial Statements. The preparation of our Financial Statements requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our Financial Statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Revenue. The majority of our future revenue is related to our SaaS and related solutions customer contracts that include variable consideration dependent upon a series of monthly volumes and/or daily usage of services and have contractual terms ending from 2024 through 2036. Our customer contracts may include guaranteed minimums and fixed monthly or annual fees. As of March 31, 2024, our aggregate amount of the transaction price allocated to the remaining performance obligations was approximately $1.4 billion, which is made up of fixed fee consideration and guaranteed minimums expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). We expect to recognize over 75% of this amount by the end of 2026, with the remaining amount recognized by the end of 2036. We have excluded from this amount variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied.

The nature, amount, timing, and uncertainty of our revenue and how revenue and cash flows are affected by economic factors is most appropriately depicted by revenue type, geographic region, and customer vertical.

Revenue by type for the quarters ended March 31, 2024 and 2023 was as follows (in thousands):

	Quarter Ended
	March 31, 2024		March 31, 2023
SaaS and related solutions	$	261,695	$	257,876
Software and services		22,394		30,891
Maintenance		11,046		9,972
Total revenue	$	295,135	$	298,739

We use the location of the customer as the basis of attributing revenue to geographic regions. Revenue by geographic region for the quarters ended March 31, 2024 and 2023, as a percentage of our total revenue, was as follows:

	Quarter Ended
	March 31, 2024			March 31, 2023
Americas (principally the U.S.)		86	%		84	%
Europe, Middle East, and Africa		9	%		12	%
Asia Pacific		5	%		4	%
Total revenue		100	%		100	%

8

We generate our revenue primarily from the global communications markets; however, we serve an expanding group of customers in other markets including retail, financial services, healthcare, insurance, and government entities. Revenue by customer vertical for the quarters ended March 31, 2024 and 2023, as a percentage of our total revenue, was as follows:

	Quarter Ended
	March 31, 2024			March 31, 2023
Broadband/Cable/Satellite		51	%		52	%
Telecommunications		19	%		20	%
Other		30	%		28	%
Total revenue		100	%		100	%

Deferred revenue as of December 31, 2023 and 2022 recognized during the quarters ended March 31, 2024 and 2023 was $19.1 million and $20.2 million, respectively.

Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less as of the date of purchase to be cash equivalents. As of March 31, 2024 and December 31, 2023, our cash equivalents consist primarily of institutional money market funds and time deposits held at major banks. For the cash and cash equivalents denominated in foreign currencies and/or located outside the U.S., we do not anticipate any material amounts being unavailable for use in running our business, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls and potential negative economic consequences.

Restricted Cash. Restricted cash includes cash that is legally or contractually restricted, as well as our settlement and merchant reserve assets (discussed below). The nature of the restrictions on our settlement and merchant reserve assets consists of contractual restrictions with the merchants and restrictions arising from our policy and intention. It has historically been our policy to segregate settlement and merchant reserve assets from our operating cash balances and our intention is to continue to do so. As of both March 31, 2024 and December 31, 2023, we had $2.9 million of restricted cash that mainly serves to collateralize bank and performance guarantees included in other current and non-current assets in our unaudited Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”).

Settlement and Merchant Reserve Assets and Liabilities. Settlement assets and settlement liabilities represent cash collected on behalf of merchants via payments processing services which is held for an established holding period until settlement with the customer. The holding period is generally one to four business days depending on the payment model and contractual terms with the customer. During the holding period, cash is subject to restriction and segregation based on the nature of our custodial relationship with the merchants. Should we fail to remit these funds to our merchants, the merchant's sole recourse for payment would be against us. These rights and obligations are set forth in the contracts between us and the merchants. Settlement assets are held with various major financial institutions and a corresponding liability is recorded for the amounts owed to the customer. At any given time, there may be differences between the cash held and the corresponding liability due to the timing of operating-related cash transfers.

Merchant reserve assets/liabilities represent deposits collected from merchants to mitigate our risk of loss due to nonperformance of settlement obligations initiated by those merchants using our payments processing services, or non-payment by customers for services rendered by us. We perform a credit risk evaluation on each customer based on multiple criteria, which provides the basis for the deposit amount required for each merchant. For the duration of our relationship with each merchant, we hold their reserve deposits with major financial institutions. We hold these funds in separate accounts, which are offset by corresponding liabilities.

The following table summarizes our settlement and merchant reserve assets and liabilities as of the indicated periods (in thousands):

	March 31, 2024				December 31, 2023
	Assets		Liabilities		Assets		Liabilities
Settlement assets/liabilities	$	178,679	$	177,207	$	260,712	$	259,825
Merchant reserve assets/liabilities		14,283		14,291		13,987		13,992
Total	$	192,962	$	191,498	$	274,699	$	273,817

Financial Instruments. Our financial instruments as of March 31, 2024 and December 31, 2023 include cash and cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, accounts payable, and debt. Due to their short maturities, the carrying amounts of cash equivalents, settlement and merchant reserve assets and liabilities, accounts receivable, and accounts payable approximate their fair value.

We have chosen not to record our debt at fair value, with changes recognized in earnings each reporting period. The following table indicates the carrying value and estimated fair value of our debt as of the indicated periods (in thousands):

	March 31, 2024				December 31, 2023
	Carrying Value		Fair Value		Carrying Value		Fair Value
2023 Convertible Notes (par value)	$	425,000	$	420,856	$	425,000	$	428,506
2021 Credit Agreement (carrying value including     current maturities)		131,250		131,250		133,125		133,125

9

The fair value of our convertible notes was estimated based upon quoted market prices or recent sales activity, while the fair value of our credit agreement was estimated using a discounted cash flow methodology, both of which are considered Level 2 inputs. See Note 4 for a discussion regarding our debt.

Pillar Two. Numerous foreign jurisdictions have enacted or are in the process of enacting legislation to adopt a minimum effective tax rate. Pillar Two, which was established by the Organization for Economic Co-operation and Development (OECD), generally provides for a 15 percent minimum effective tax rate for multinational enterprises in every jurisdiction in which they operate. The U.S. has not yet adopted Pillar Two, however, various other governments around the world have. These rules did not have a material impact on our taxes for the three months ended March 31, 2024. We continue to monitor evolving tax legislation in the jurisdictions in which we operate.

Accounting Pronouncements Issued but Not Yet Effective. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), (“ASU 2023-07”), which enhances reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. ASU 2023-07 also requires disclosure of the title and position of the company’s Chief Operating Decision Maker (“CODM”) and how the CODM uses financial reporting to assess segment performance and allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires entities to disclose more detailed information about their effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are in the process of evaluating what impact this ASU will have on our Financial Statements and disclosures.

2023 Convertible Notes. The 2023 Convertible Notes will be convertible at the option of the noteholders before June 15, 2028, upon the occurrence of certain events. On or after June 15, 2028, and until the close of business on the second scheduled trading day immediately preceding September 15, 2028, the maturity date, noteholders may convert all or any portion of their notes at any time regardless of these conditions.

The 2023 Convertible Notes will be convertible at an initial conversion rate of 14.0753 shares of our common stock per $1,000 principal amount of the 2023 Convertible Notes, which is equivalent to an initial conversion price of $71.05 per share of our common stock, plus carryforward adjustments not yet effected pursuant to the terms of the indenture governing the 2023 Convertible Notes. Under the terms of the 2023 Convertible Notes, we will adjust the conversion rate for any quarterly dividends exceeding $0.28 per share.

We are required to satisfy our conversion obligation as follows: (i) paying cash up to the aggregate principal amount of notes to be converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we will satisfy the remaining conversion obligation in our common stock, cash, or a combination thereof, at our election. As of March 31, 2024, none of the conditions to early convert have been met.

We may not redeem the 2023 Convertible Notes prior to September 21, 2026. On or after September 21, 2026, we may redeem for cash all or part of the 2023 Convertible Notes, subject to a partial redemption limitation that requires at least $100.0 million of the principal amount of the 2023 Convertible Notes to remain outstanding if the last reported sales price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. The redemption price will equal the principal amount of the 2023 Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund has been established for the 2023 Convertible Notes.

In connection with the pricing of the 2023 Convertible Notes, we entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain of the initial purchasers of the 2023 Convertible Notes and other financial institutions (collectively, the “Option Counterparties”). As of March 31, 2024, all the Capped Call Transactions were outstanding and cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2023 Convertible Notes, 5.98 million shares of our common stock, the same number of shares of common stock underlying the 2023 Convertible Notes. The Capped Call Transactions will expire upon the maturity of the 2023 Convertible Notes.

2021 Credit Agreement. During the quarter ended March 31, 2024, we made $1.9 million of principal repayments on our $150.0 million aggregate principal five-year term loan (the “2021 Term Loan”). As of March 31, 2024, we had no borrowings outstanding on our $450.0 million aggregate principal five-year revolving loan facility (the "2021 Revolver"), however we had issued a standby letter of credit of $1.2 million that counts against our available 2021 Revolver balance. In April 2024, we borrowed $15.0 million on the 2021 Revolver, currently leaving $433.8 million available to us.

As of March 31, 2024, our interest rate on the 2021 Term Loan was 6.777% (adjusted Secured Overnight Financing Rate ("SOFR"), credit spread adjustment of 0.10%, plus 1.375% per annum), effective through June 2024, and our commitment fee on the 2021 Revolver was 0.15%.

The interest rates under the 2021 Credit Agreement are based upon our choice of an adjusted SOFR rate plus an applicable margin of 1.375% - 2.125%, or an alternate base rate (“ABR”) plus an applicable margin of 0.375% - 1.125%, with the applicable margin determined in accordance with our then-net secured total leverage ratio. We pay a commitment fee of 0.150% - 0.325% of the average daily unused amount of the 2021 Revolver, with the commitment fee rate also determined in accordance with our then-net secured total leverage ratio.

5. ACQUISITIONS

DGIT Systems Pty Ltd. On October 4, 2021, we acquired DGIT Systems Pty Ltd (“DGIT”), a provider of configure, price and quote (CPQ) and order management solutions for the telecommunications industry. We acquired 100% of the equity of DGIT for a purchase price of approximately $16 million, approximately $14 million paid upon close and the remaining consideration of approximately $2 million to be paid through 2025, subject to certain reductions, as applicable. During the first quarter of 2024, we made a purchase price payment of $0.5 million.

The DGIT acquisition includes provisions for up to approximately $13 million of potential future earn-out payments. The earn-out payments are tied to performance-based goals and a defined service period by the eligible recipients and are accounted for as post-acquisition compensation, as applicable. The earn-out period is through September 30, 2025.

Subsequent Event. On April 1, 2024, we acquired certain assets of a customer communication services business that operates in multiple industry verticals for a purchase price of $11.5 million, subject to customary working capital adjustments. The results of this acquisition will be included in our results of operations for the period subsequent to the acquisition date.

6. RESTRUCTURING AND REORGANIZATION CHARGES

During the first quarters of 2024 and 2023, we recorded restructuring and reorganization charges of $2.0 million and $5.2 million, respectively.

During the first quarter of 2024 we reduced our workforce by approximately 35 employees, mainly in the U.S., as a result of organizational changes and efficiencies. As a result, we incurred restructuring charges related to involuntary terminations of $1.6 million.

The activity in the restructuring and reorganization reserves during the first quarter of 2024 was as follows (in thousands):

	Termination Benefits			Other			Total
January 1, 2023, balance	$	1,434		$	8,100		$	9,534
Charged to expense during period		1,582			416			1,998
Cash payments		(1,288	)		(4,196	)		(5,484	)
Other		115			-			115
March 31, 2024, balance	$	1,843		$	4,320		$	6,163

As of March 31, 2024, $4.9 million of the restructuring and reorganization reserves were included in current liabilities.

7. COMMITMENTS, GUARANTEES AND CONTINGENCIES

Guarantees. In the ordinary course of business, we may provide guarantees in the form of bid bonds or performance bonds. As of March 31, 2024, we had $2.9 million of restricted assets used to collateralize these guarantees, with $0.4 million included in other current assets and $2.5 million included in other non-current assets.

We have performance guarantees in the form of surety bonds and a standby letter of credit, along with money transmitter bonds, issued through third-parties that are not required to be reflected on our Balance Sheets. As of March 31, 2024, we had performance guarantees of $6.0 million, which includes a $1.2 million standby letter of credit. We are ultimately liable for claims that may occur against these guarantees. We have no history of material claims or are aware of circumstances that would require us to pay under any of these arrangements. We also believe that the resolution of any claim that may arise in the future, either individually or in the aggregate, would not be material to our Financial Statements. As of March 31, 2024, we had total aggregate money transmitter bonds of $20.8 million outstanding. These money transmitter bonds are for the benefit of various states to comply with the states’ financial requirements and industry regulations for money transmitter licenses.

Warranties. We generally warrant that our solutions and related offerings will conform to published specifications, or to specifications provided in an individual customer arrangement, as applicable. The typical warranty period is 90 days from the date of acceptance of the solution or offering. For certain service offerings we provide a warranty for the duration of the services provided. We generally warrant that those services will be performed in a professional and skillful manner. The typical remedy for breach of warranty is to correct or replace any defective deliverable, and if not possible or practical, we will accept the return of the defective deliverable and refund the amount paid under the customer arrangement that is allocable to the defective deliverable. Our contracts also generally contain limitation of damages provisions in an effort to reduce our exposure to monetary damages arising from breach of warranty claims. Historically, we have incurred minimal warranty costs, and as a result, do not maintain a warranty reserve.

Solution and Services Indemnifications. Arrangements with our customers generally include an indemnification provision that will indemnify and defend a customer in actions brought against the customer that claim our products and/or services infringe upon a copyright, trade secret, or valid patent. Historically, we have not incurred any significant costs related to such indemnification claims, and as a result, do not maintain a reserve for such exposure.

Claims for Company Non-performance. Our arrangements with our customers typically limit our liability for breach to a specified amount of the direct damages incurred by the customer resulting from the breach. From time-to-time, these arrangements may also include provisions for possible liquidated damages or other financial remedies for our non-performance, or in the case of certain of our solutions, provisions for damages related to service level performance requirements. The service level performance requirements typically relate to system availability and timeliness of service delivery. As of March 31, 2024, we believe we have adequate reserves, based on our historical experience, to cover any reasonably anticipated exposure as a result of our nonperformance for any past or current arrangements with our customers.

Indemnifications Related to Officers and the Board of Directors. Other guarantees include promises to indemnify, defend, and hold harmless our directors, and certain officers. Such indemnification covers any expenses and liabilities reasonably incurred by a person, by reason of the fact that such person is, was, or has agreed to be a director or officer, in connection with the investigation, defense, and settlement of any threatened, pending, or contemplated action, suit, proceeding, or claim. We maintain directors’ and officers’ (“D&O”) insurance coverage to protect against such losses. We have not historically incurred any losses related to these types of indemnifications and are not aware of any pending or threatened actions or claims against any officer or member of our Board of Directors (the "Board"). As a result, we have not recorded any liabilities related to such indemnifications as of March 31, 2024. In addition, as a result of the insurance policy coverage, we believe these indemnification agreements are not significant to our results of operations.

Legal Proceedings. From time to time, we are involved in litigation relating to claims arising out of our operations in the normal course of business.

8. EARNINGS PER COMMON SHARE

Basic and diluted earnings per common share (“EPS”) amounts are presented on the face of our unaudited Condensed Consolidated Statements of Income (the "Income Statements").

The reconciliation of the basic and diluted EPS denominators related to common shares is included in the following table (in thousands):

	Quarter Ended
	March 31, 2024		March 31, 2023
Basic weighted-average common shares		28,516		30,418
Dilutive effect of restricted common stock		281		191
Diluted weighted-average common shares		28,797		30,609

13

The dilutive effect of restricted common stock is computed using the treasury stock method. The dilutive effect of the 2023 Convertible Notes is computed using the if-converted method and will only have an effect in those quarterly periods in which our average stock price exceeds the current effective conversion price.

Potentially dilutive common shares related to non-participating unvested restricted stock and stock warrants were excluded from the computation of diluted EPS, as the effect was anti-dilutive, and were not material in any period presented. Stock warrants (see Note 9) will only have a dilutive effect upon vesting in those periods in which our average stock price exceeds the exercise price of $26.68 per warrant.

9. STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION PLANS

Stock Repurchase Program. We currently have a stock repurchase program, approved by our Board, authorizing us to repurchase shares of our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). During the first quarter of 2024, we repurchased approximately 185,000 shares of our common stock for $9.6 million (weighted-average price of $51.96 per share) under a SEC Rule 10b5-1 Plan. We did not make any share repurchases during the first quarter of 2023.

The excise tax imposed as part of the 2022 Inflation Reduction Act, which is included as a cost of treasury stock, is not reflected in the share repurchase amount above.

As of March 31, 2024, the total remaining value of shares available for repurchase under the Stock Repurchase Program totaled $86.2 million.

Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the first quarters of 2024 and 2023, we repurchased and then cancelled approximately 159,000 shares of common stock for $8.5 million and approximately 166,000 shares of common stock for $9.3 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plan.

Cash Dividends. During the first quarter of 2024, our Board approved a quarterly cash dividend of $0.30 per share of common stock, totaling $8.9 million. During the first quarter of 2023, our Board approved a quarterly cash dividend of $0.28 per share of common stock, totaling $8.8 million.

Warrants. In July 2014, in conjunction with the execution of an amendment to our agreement with Comcast Corporation (“Comcast”), we issued stock warrants (the “Warrant Agreement”) for the right to purchase up to 2.9 million shares of our common stock (the “Stock Warrants”) as an additional incentive for Comcast to convert customer accounts onto our solutions based on various milestones. The Stock Warrants have a ten-year term and an exercise price of $26.68 per warrant.

As of March 31, 2024, 1.0 million Stock Warrants remain issued, none of which have vested. The remaining unvested Stock Warrants will be accounted for as a customer contract cost asset once the performance conditions necessary for vesting are considered probable.

Stock-Based Awards. During the first quarter of 2024 we granted restricted stock awards to key members of management in the form of: (i) performance-based awards of approximately 155,000 restricted common stock shares, which vest in the first quarter of 2026 upon meeting certain pre-established financial performance objectives over a two-year performance period; and (ii) market-based awards of approximately 52,000 restricted common stock shares, which vest in the first quarter of 2027 upon meeting a relative total shareholder return performance achievement tier. Certain of these awards may vest (i.e., vesting accelerates) upon the involuntary termination of employment or a change in control, as defined, and the subsequent involuntary termination of employment.

During the first quarter of 2024, we also granted restricted stock awards to key members of management in the form of time-based awards of approximately 414,000 restricted common stock shares, which vest annually over three years with no restrictions other than the passage of time. Certain of these awards may vest (i.e., vesting accelerates) upon the involuntary termination of employment, a change in control, as defined, and the subsequent involuntary termination of employment, or death.

We recorded stock-based compensation expense for the first quarters of 2024 and 2023 of $7.7 million and $6.4 million, respectively.

Management Overview of Quarterly Results

First Quarter Highlights. A summary of our results of operations for the first quarter of 2024, when compared to the first quarter of 2023, is as follows (in thousands, except per share amounts and percentages):

	Quarter Ended
	March 31, 2024			March 31, 2023
Revenue	$	295,135		$	298,739
Transaction fees (1)		25,062			21,973
Operating Results:
Operating income	$	31,797		$	38,193
Operating margin percentage		10.8	%		12.8	%
Diluted EPS	$	0.68		$	0.68
Supplemental Data:
Restructuring and reorganization charges (2)	$	1,998		$	5,194
Executive transition costs		352			-
Acquisition-related costs:
Amortization of acquired intangible assets		2,852			3,209
Transaction-related costs		-			158
Stock-based compensation (2)		7,869			6,757

(1)Transaction fees are primarily comprised of fees paid to third-party payment processors and financial institutions and interchange fees under our payment services contracts. Transaction fees are included in revenue in our Income Statement (and not netted against revenue) because we maintain control and act as the principal over the integrated service provided under our payment services customer contracts.

(2)Restructuring and reorganization charges include stock-based compensation, which is not included in the stock-based compensation line in the table above, and depreciation, which has not been recorded to the depreciation line on our Income Statement.

Revenue. Revenue for the first quarter of 2024 was $295.1 million, a 1.2% decrease when compared to revenue of $298.7 million for the first quarter of 2023. The decrease in revenue is primarily attributed to lower software and services revenue in the first quarter of 2024, resulting from the closure of approximately $10 million of software license upgrades in the first quarter of 2023. This was offset to a certain degree by the continued growth of our SaaS and related solutions revenue, to include our payments solutions.

Operating Results. Operating income for the first quarter of 2024 was $31.8 million, or a 10.8% operating margin percentage, compared to $38.2 million, or a 12.8% operating margin percentage for the first quarter of 2023. The decrease in operating income is mainly attributed to the higher software and services revenue recognized in the first quarter of 2023, discussed above, as the costs associated with this revenue is not generally dependent upon on the timing of the deal closure, offset to a certain degree by lower restructuring and reorganization charges.

Diluted EPS. Diluted EPS for the first quarter of 2024 and 2023 was $0.68, for both periods, with the first quarter of 2024 benefiting primarily from foreign currency movements and a lower share count.

Cash and Cash Flows. As of March 31, 2024, we had cash and cash equivalents of $120.8 million, as compared to $186.3 million as of December 31, 2023. Our cash flows used in operating activities for the first quarter of 2024 were ($29.4) million. Cash flows for the first quarter of 2024 were negatively impacted by unfavorable working capital changes, to include the payment of 2023 accrued employee incentive compensation. See the Liquidity section below for further discussion of our cash flows.

16

Significant Customer Relationships

A large percentage of our revenue is generated from a limited number of customers in the global communications industry, with our three largest customers being Charter Communications Inc. (“Charter”), Comcast, and DISH Network L.L.C.

Customer Concentration. We have significant customer concentration, with the following two customers exceeding 10% of our revenue (in thousands, except percentages):

	Quarter Ended
	March 31, 2024					December 31, 2023					March 31, 2023
	Amount		% of Revenue			Amount		% of Revenue			Amount		% of Revenue
Charter	$	60,849		21	%	$	60,128		20	%	$	61,532		21	%
Comcast		52,804		18	%		54,651		18	%		53,415		18	%

The percentages of net billed accounts receivable balances attributable to these customers as of the indicated dates were as follows:

	As of
	March 31, 2024			December 31, 2023			March 31, 2023
Charter		21	%		23	%		22	%
Comcast		18	%		17	%		19	%

See our 2023 10-K for additional discussion of our business relationships and contractual terms with Comcast and Charter.

Risk of Customer Concentration. We expect to continue to generate a large percentage of our future revenue from a limited number customers. There are inherent risks whenever a large percentage of total revenue is concentrated with a limited number of customers. Should a significant customer: (i) terminate or fail to renew their contracts with us, in whole or in part, for any reason; (ii) significantly reduce the number of customer accounts processed on our solutions, the price paid for our services, or the scope of services that we provide; or (iii) experience financial or operating difficulties, it could have a material adverse effect on our financial position and results of operations.

Critical Accounting Policies

The preparation of our Financial Statements in conformity with U.S. GAAP requires us to select appropriate accounting policies, and to make judgments and estimates affecting the application of those accounting policies. In applying our accounting policies, different business conditions or the use of different assumptions may result in materially different amounts reported in our Financial Statements.

We have identified the most critical accounting policies that affect our financial position and the results of our operations. Those critical accounting policies were determined by considering the accounting policies that involve the most complex or subjective decisions or assessments. The most critical accounting policies identified relate to the following items: (i) revenue recognition; (ii) impairment assessments of long-lived assets; (iii) income taxes; and (iv) loss contingencies. These critical accounting policies, as well as our other significant accounting policies, are discussed in our 2023 10-K.

Results of Operations

Revenue. Total revenue for the first quarter of 2024 was $295.1 million, a 1.2% decrease when compared to $298.7 million for the first quarter of 2023.

Revenue by type for the first quarters of 2024 and 2023 was as follows (in thousands):

	Quarter Ended
	March 31, 2024		March 31, 2023
SaaS and related solutions	$	261,695	$	257,876
Software and services		22,394		30,891
Maintenance		11,046		9,972
Total revenue	$	295,135	$	298,739

17

The decrease in revenue is primarily attributed to lower software and services revenue in the first quarter of 2024 resulting from the closure of approximately $10 million of software license upgrades in the first quarter of 2023. This was offset to a certain degree by the continued growth of our SaaS and related solutions revenue, to include our payments solutions.

We use the location of the customer as the basis of attributing revenue to individual countries. Revenue by geographic regions for the first quarters of 2024 and 2023 was as follows (in thousands):

	Quarter Ended
	March 31, 2024		March 31, 2023
Americas (principally the U.S.)	$	254,538	$	250,976
Europe, Middle East, and Africa		26,829		36,673
Asia Pacific		13,768		11,090
Total revenue	$	295,135	$	298,739

Total Operating Expenses. Total operating expenses for the first quarter of 2024 were $263.3 million, a 1.1% increase when compared to $260.5 million for the first quarter of 2023. The increases in total operating expenses are reflective of the higher SaaS and related solutions revenue between periods, partially offset by the decrease in restructuring and reorganization charges, discussed below.

The components of total operating expenses are discussed in more detail below.

Cost of Revenue (Exclusive of Depreciation). The cost of revenue for the first quarter of 2024 was $157.9 million, a 1.8% increase when compared to $155.0 million for the first quarter of 2023. The increase in cost of revenue between periods is reflective of the increase in SaaS and related solutions revenue year-over-year. Total cost of revenue as a percentage of revenue for the first quarters of 2024 and 2023 was 53.5% and 51.9%, respectively.

R&D Expense (Exclusive of Depreciation). R&D expense for the first quarter of 2024 was $36.1 million, a 1.8% increase when compared to $35.5 million for the first quarter of 2023. The increase in R&D expense between periods is mainly attributed to increased employee-related costs. Our R&D efforts are focused on the continued evolution of our solutions that enable us to launch, monetize, and scale new digital services quickly and across any channel, while delivering an exceptional customer experience. As a percentage of total revenue, R&D expense for the first quarters of 2024 and 2023 was 12.2% and 11.9%, respectively.

Selling, General, and Administrative ("SG&A") Expense (Exclusive of Depreciation). SG&A expense for the first quarter of 2024 was $61.7 million, a 4.4% increase when compared to $59.1 million for the first quarter of 2023. The increase in SG&A expense is primarily attributed to increases in employee-related costs, to include stock-based compensation and travel expense. As a percentage of total revenue, SG&A expense for the first quarters of 2024 and 2023 was 20.9% and 19.8%, respectively.

Restructuring and Reorganization Charges. Restructuring and reorganization charges for the first quarter of 2024 were $2.0 million, a $3.2 million decrease when compared to $5.2 million for the first quarter of 2023. The restructuring and reorganization charges for the first quarter of 2024 relate mainly to a reduction in workforce resulting in restructuring charges related to involuntary terminations of $1.6 million.

See Note 6 to our Financial Statements for additional discussion.

Operating Income. Operating income for the first quarter of 2024 was $31.8 million, or 10.8% of total revenue, compared to $38.2 million, or 12.8% of total revenue for the first quarter of 2023. The decrease in operating income is mainly attributed to the $10 million of software license revenue recognized in the first quarter of 2023, discussed above, as the cost associated with this revenue is not generally dependent upon on the timing of the deal closures, offset to a certain degree by lower restructuring and reorganization charges.

Interest Expense. Interest expense for the first quarter of 2024 was $7.5 million, a 4.0% increase when compared to $7.2 million for the first quarter of 2023. Our interest expense relates primarily to the 2023 Convertible Notes and 2021 Credit Agreement. The increase in interest expense between periods can be attributed to a higher outstanding debt balance during the first quarter of 2024, partially offset by a lower average interest rate.

See Note 4 to our Financial Statements for additional discussion of our long-term debt.

Interest Income. Interest income for the first quarter of 2024 was $2.6 million, a $2.0 million increase when compared to $0.6 million for the first quarter of 2023, with the increase primarily attributed to certain settlement assets being swept into overnight money market accounts on a daily basis.

Other, net. Other, net for the first quarter of 2024 was $0.6 million of other income, a $3.0 million change when compared to $2.4 million of other expense for the first quarter of 2023, with the change primarily attributed to foreign currency movements.

18

Income Tax Provision. The effective income tax rates for the first quarters of 2024 and 2023 were 29% and 28%, respectively. Our estimated full year 2024 effective income tax rate is approximately 29%, a slight increase when compared to our 2023 full year rate of approximately 28%.

Liquidity

Cash and Liquidity. As of March 31, 2024, our principal sources of liquidity included cash and cash equivalents of $120.8 million, compared to $186.3 million as of December 31, 2023.

As part of our 2021 Credit Agreement, we have a $450.0 million senior secured revolving loan facility with a syndicate of financial institutions that expires in September 2026, the 2021 Revolver. As of March 31, 2024, there were no borrowings outstanding on the 2021 Revolver balance, however we issued a standby letter of credit for $1.2 million that counts against the available 2021 Revolver balance. In April 2024, we borrowed $15.0 million on the 2021 Revolver, for general corporate purposes, currently leaving $433.8 million available to us. The 2021 Credit Agreement contains customary affirmative, negative, and financial covenants. As of March 31, 2024, and the date of this filing, we believe we are in compliance with the provisions of the 2021 Credit Agreement.

Our cash and cash equivalents balances as of the end of the indicated periods were located in the following geographical regions (in thousands):

	March 31, 2024		December 31, 2023
Americas (principally the U.S.)	$	87,718	$	142,515
Europe, Middle East and Africa		22,311		32,974
Asia Pacific		10,781		10,775
Total cash and cash equivalents	$	120,810	$	186,264

We generally have ready access to substantially all of our cash and cash equivalents, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls and potential negative economic consequences.

As of March 31, 2024 and December 31, 2024, we had $2.9 million, for both periods, of cash restricted as to use primarily to collateralize guarantees and outstanding letters of credit included in our other current and non-current asset balances. In addition, as of March 31, 2024 and December 31, 2023, we had $193.0 million and $274.7 million, respectively, of settlement and merchant reserve assets which are deemed restricted due to contractual restrictions with the merchants and restrictions arising from our policy and intention. It has historically been our policy to segregate settlement and merchant reserve assets from our operating cash balances and we intend to continue to do so.

Cash Flows from Operating Activities. We calculate our cash flows from operating activities beginning with net income, adding back the impact of non-cash items or non-operating activity (e.g., depreciation, amortization, impairments, gain/loss on items such as investments, lease modifications, and debt extinguishments/conversions, unrealized foreign currency transactions gain/loss, deferred income taxes, stock-based compensation, etc.), and then factoring in the impact of changes in operating assets and liabilities. See our 2023 10-K for a description of the primary uses and sources of our cash flows from operating activities.

Our cash flows from operating activities, broken out between operations and changes in operating assets and liabilities, for the indicated quarterly periods are as follows (in thousands):

	Operations		Changes in Operating Asset and Liabilities			Net Cash Provided by (Used In) Operating Activities – Totals
Cash Flows from Operating Activities:
2024:
March 31 (1)	$	51,655	$	(81,006	)	$	(29,351	)
2023:
March 31 (2)	$	50,158	$	(34,761	)	$	15,397

(1)Cash flows from operating activities for the first quarter of 2024 were negatively impacted by unfavorable working capital changes, to include the impact of the payment of the 2023 year-end accrued employee incentive compensation and timing of trade accounts receivable.

(2)Cash flows from operating activities for the first quarter 2023 reflect the impact of the payment of the 2022 year-end accrued employee incentive compensation.

Variations in our net cash provided by/(used in) operating activities are generally related to the changes in our operating assets and liabilities (related mostly to fluctuations in timing at quarter-end of customer payments, billing milestones, and changes in accrued expenses), and generally over longer periods of time, do not significantly impact our cash flows from operations.

19

Significant fluctuations in key operating assets and liabilities between 2024 and 2023 that impacted our cash flows from operating activities are as follows:

Billed Trade Accounts Receivable

Management of our billed trade accounts receivable is one of the primary factors in maintaining strong cash flows from operating activities. These balances include significant billings for several non-revenue items (primarily postage, sales tax, and deferred revenue items). As a result, we evaluate our performance in collecting our billed trade accounts receivable through our calculation of Days Billings Outstanding (“DBO”) rather than a typical Days Sales Outstanding (“DSO”) calculation.

Our gross and net billed trade accounts receivable and related allowance for expected losses (“Allowance”) as of the end of the indicated quarterly periods, and the related DBOs for the quarters then ended, are as follows (in thousands, except DBOs):

Quarter Ended	Gross		Allowance			Net Billed		DBOs
2024:
March 31	$	281,051	$	(5,692	)	$	275,359		67
2023:
March 31	$	261,028	$	(5,254	)	$	255,774		68

As of March 31, 2024 and 2023, approximately 95%, for both periods, of our net billed trade accounts receivable balances were less than 60 days past due.

We may experience adverse impacts to our DBOs if and when customer payment delays occur. However, these recurring monthly payments that cross a reporting period-end do not raise collectability concerns, as payment is generally received subsequent to quarter-end. All other changes in our gross and net billed accounts receivable reflect the normal fluctuations in the timing of customer payments at quarter-end, as evidenced by our relatively consistent DBO metric.

As a global provider of solutions and services, a portion of our trade accounts receivable balance relates to international customers. This diversity in the geographic composition of our customer base may adversely impact our DBOs as longer billing cycles (i.e., billing terms and cash collection cycles) are an inherent characteristic of international software and professional services transactions. As a result, we may experience fluctuations in our trade accounts receivable balance as our ability to invoice and collect arrangement fees is dependent upon, among other things: (i) the completion of various customer administrative matters, local country billing protocols and processes (including local cultural differences), and non-customer administrative matters; (ii) meeting certain contractual invoicing milestones and dates; (iii) the overall project status in certain situations in which we act as a subcontractor to another vendor on a project; or (iv) currency controls in certain foreign jurisdictions.

Unbilled Trade Accounts Receivable

Unbilled trade accounts receivable increased $2.1 million to $84.3 million as of March 31, 2024, from $82.2 million as of December 31, 2023. These unbilled trade accounts receivable balances relate primarily to large implementation projects where various milestone and contractual billing dates have not yet been reached or delayed. Unbilled trade accounts receivable are an inherent characteristic of certain software and services transactions and may fluctuate between quarters, as these types of transactions typically have scheduled invoicing terms over several quarters, as well as certain milestone billing events.

Accrued Employee Compensation

Accrued employee compensation decreased $40.4 million to $44.0 million as of March 31, 2024, from $84.4 million as of December 31, 2023, due primarily to the payment of the 2023 employee incentive compensation during the first quarter of 2024 that was fully accrued at December 31, 2023.

Other Current and Non-current Liabilities

Other current and non-current liabilities decreased $11.9 million to $34.5 million as of March 31, 2024, from $46.4 million as of December 31, 2023, primarily due to a decrease of $4.3 million related to accrued interest on our outstanding debt and payments related to the exit of our reseller agreements of $3.8 million.

Cash Flows From Investing Activities. Our typical investing activities consist of purchases of software, property, and equipment, which are discussed below.

Purchases of Software, Property, and Equipment

Our capital expenditures for the first quarters of 2024 and 2023 for software, property, and equipment were $4.8 million and $8.7 million, respectively, and consisted principally of investments in: (i) software and related equipment; and (ii) computer hardware.

20

Cash Flows From Financing Activities. Our financing activities typically consist of activities with our common stock, various debt-related transactions, and settlement and merchant reserve activity.

Cash Dividends Paid on Common Stock

During the first quarters of 2024 and 2023, our Board approved dividends totaling $8.9 million and $8.8 million, respectively, and we made dividend payments of $9.5 million and $9.1 million, respectively, with the differences between the amount approved and paid attributed to dividends accrued on unvested incentive shares that are paid upon vesting.

Repurchase of Common Stock

During the first quarter of 2024, we repurchased approximately 185,000 shares of our common stock under our Stock Repurchase Program for $9.6 million. We did not make any share repurchases during the first quarter of 2023.

Additionally, outside of our Stock Repurchase Program, during the first quarters of 2024 and 2023, we repurchased from our employees and then canceled approximately 159,000 and 166,000 shares of our common stock, respectively, for $8.5 million and $9.3 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted stock under our stock incentive plans.

Through the first quarters of 2024 and 2023, we have paid $18.0 million and $9.3 million, respectively, for our total repurchases of common stock, with any differences when compared to the amounts purchased attributed to the timing of the settlement.

See Note 9 to our Financial Statements for additional discussion of our repurchases of common stock.

Long-Term Debt

During the first quarters of 2024 and 2023, we made principal repayments on our 2021 Term Loan of $1.9 million during each period. Additionally, during the first quarter of 2023, we borrowed $30.0 million from our 2021 Revolver for general corporate purposes.

See Note 4 to our Financial Statements for additional discussion of our long-term debt.

Settlement and Merchant Reserve Activity

During the first quarters of 2024 and 2023, we had net settlement and merchant reserve activity of $82.2 million and $61.5 million, respectively, related to the cash collected, held on behalf, and paid to our merchants related to our payments services and the net change in deposits held on behalf of our merchants. These balances can significantly fluctuate between periods due to activity at the end of the period and the day in which the period ends.

See Note 2 to our Financial Statements for additional discussion of our settlement and merchant reserves.

Off-Balance Sheet Arrangements

Our off-balance sheet arrangements are mainly limited to money transmitter bonds, performance bonds, and a standby letter of credit. These arrangements do not have a material impact and are not reasonably likely to have a material future impact to our financial condition, results of operations, liquidity, capital expenditures, or capital resources. See Note 7 to our Financial Statements for additional information on these guarantees.

21

Capital Resources

The following are the key items to consider in assessing our sources and uses of capital resources:

Current Sources of Capital Resources. Below are the key items to consider in assessing our current sources of capital resources:

•Cash and Cash Equivalents. As of March 31, 2024, we had cash and cash equivalents of $120.8 million, of which approximately 66% is in U.S. dollars and held in the U.S. For the remainder of the monies denominated in foreign currencies and/or located outside the U.S., we do not anticipate any material amounts being unavailable for use in funding our business, but may face limitations on moving cash out of certain foreign jurisdictions due to currency controls and potential negative economic consequences.

•Operating Cash Flows. As described in the Liquidity section above, we believe we have the ability to generate strong cash flows to fund our operating activities and act as a source of funds for our capital resource needs, although we may experience quarterly variations in our cash flows from operations related to the changes in our operating assets and liabilities.

•Revolving Loan Facility. As part of our 2021 Credit Agreement, we have a $450.0 million revolving loan facility, the 2021 Revolver. As of March 31, 2024, we had no borrowings outstanding on the 2021 Revolver, however we had issued a standby letter of credit for $1.2 million that counts against the available 2021 Revolver balance. In April 2024, we borrowed $15.0 million on the 2021 Revolver, currently leaving $433.8 million available to us. Our long-term debt obligations are discussed in more detail in Note 4 to our Financial Statements.

Uses/Potential Uses of Capital Resources. Below are the key items to consider in assessing our uses/potential uses of capital resources:

•Common Stock Repurchases. We have made repurchases of our common stock in the past under our Stock Repurchase Program. As of March 31, 2024, we had $86.2 million authorized for repurchase remaining under our Stock Repurchase Program. Our 2021 Credit Agreement places certain limitations on our ability to repurchase our common stock.

Under our Stock Repurchase Program, we may repurchase shares in the open market or in privately negotiated transactions, including through an accelerated stock repurchase plan or under a SEC Rule 10b5-1 plan. The actual timing and amount of share repurchases are dependent on the current market conditions and other business-related factors. Our common stock repurchases are discussed in more detail in Note 9 to our Financial Statements.

During the first quarter of 2024, we repurchased approximately 185,000 shares of our common stock for $9.6 million (weighted-average price of $51.96 per share).

Outside of our Stock Repurchase Program, during the first quarter of 2024, we repurchased from our employees and then cancelled approximately 159,000 shares of our common stock for $8.5 million in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans.

•Cash Dividends. During the first quarter of 2024, the Board declared dividends totaling $8.9 million. Going forward, we expect to pay cash dividends each year in March, June, September, and December, with the amount and timing subject to the Board’s approval.

•Acquisitions. As a result of our previous acquisition activity, during the first quarter of 2024 we made $0.5 million of deferred acquisition payments. We expect to pay an additional $2.0 million in 2024 and $0.3 million in 2025 related to these past acquisitions. Additionally, there are provisions for up to approximately $13 million of potential future earn-out payments. The earn-out period is through September 30, 2025.

On April 1, 2024, we acquired certain assets of a customer communication services business that operates in multiple industry verticals for a purchase price of $11.5 million, subject to customary working capital adjustments.

Our acquisitions are discussed in more detail in Note 5 to our Financial Statements. As part of our growth strategy, we are continually evaluating potential business and/or asset acquisitions and investments in market share expansion with our existing and potential new customers and expansion into verticals outside the global communications market.

22

•Exit of Reseller Agreements. During 2023, we exited out of two reseller agreements that were acquired with the acquisition of Forte Payment Systems, Inc. in 2018, at a total cost of $9.9 million, of which $1.8 million was paid in 2023. We paid $3.8 million during the first quarter of 2024, with an additional $1.8 million to be paid in the second quarter of 2024. Of the remaining $2.5 million, $1.3 million will be paid in 2025 and $1.2 million will be paid in 2026.

•Capital Expenditures. During the first quarter of 2024, we spent $4.8 million on capital expenditures.

•Stock Warrants. In July 2014, we issued stock warrants with an exercise price of $26.68 per warrant to Comcast as an incentive for Comcast to convert new customer accounts onto our solutions. Once vested, Comcast may exercise the stock warrants and elect either physical delivery of common shares or net share settlement (cashless exercise). Alternatively, the exercise of the stock warrants may be settled with cash based solely on our approval, or if Comcast were to beneficially own or control in excess of 19.99% of the common stock or voting of the Company. As of March 31, 2024, 1.0 million stock warrants were outstanding, none of which were vested.

The stock warrants are discussed in more detail in Note 9 to our Financial Statements.

•Long-Term Debt. As of March 31, 2024, our long-term debt consisted of the following: (i) 2023 Convertible Notes in the principal aggregate amount of $425.0 million; and (ii) 2021 Credit Agreement term loan borrowings of $131.3 million.

2023 Convertible Notes. The 2023 Convertible Notes are convertible at the option of the note holders before June 15, 2028 upon the occurrence of certain events, however, there are no scheduled conversion triggers over the next twelve months. As a result, we expect our required debt service cash outlay during the next twelve months for the 2023 Convertible Notes to be limited to interest payments of $16.5 million.

2021 Credit Agreement. The mandatory repayments under our 2021 Credit Agreement for the next twelve months are $7.5 million and the cash interest expense (based upon then-current interest rates) for the 2021 Term Loan and 2021 Revolver (to include the $15.0 million that was borrowed in April 2024, assuming no further amounts are borrowed, and the amount is not paid down) is $9.9 million. We have the ability to make prepayments without penalties on our 2021 Credit Agreement.

Our long-term debt obligations are discussed in more detail in Note 4 to our Financial Statements.

In summary, we expect to continue to have material needs for capital resources going forward, as noted above. We believe that our current cash and cash equivalents balances and our 2021 Revolver, together with cash expected to be generated in the future from our current operating activities, will be sufficient to meet our anticipated capital resource requirements for at least the next twelve months. We believe we could obtain additional capital through other debt sources which may be available to us if deemed appropriate.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential loss arising from adverse changes in market rates and prices. As of March 31, 2024, we are exposed to various market risks, including changes in interest rates, fluctuations and changes in the market value of our cash equivalents and settlement and merchant reserve assets, and changes in foreign currency exchange rates. We have not historically entered into derivatives or other financial instruments for trading or speculative purposes.

Interest Rate Risk

Long-Term Debt. The interest rate on our 2023 Convertible Notes is fixed, and thus, as it relates to our convertible debt borrowings, we are not exposed to changes in interest rates.

The interest rates on our 2021 Credit Agreement are based upon an adjusted SOFR rate (including 0.10% credit spread adjustment) plus an applicable margin, or an ABR plus an applicable margin. See Note 4 to our Financial Statements for further details related to our long-term debt.

A hypothetical adverse change of 10% in the March 31, 2024 adjusted SOFR rate would not have a material impact upon our results of operations.

Market Risk

Cash and Cash Equivalents. Our cash and cash equivalents as of March 31, 2024 and December 31, 2023 were $120.8 million and $186.3 million, respectively. Certain of our cash balances are swept into overnight money market accounts on a daily basis, and at times, any excess funds are invested in low-risk, somewhat longer term, cash equivalent instruments. Our cash equivalents are invested primarily in institutional money market funds held at major banks. We have minimal market risk for our cash and cash equivalents due to the relatively short maturities of the instruments.

23

Settlement and Merchant Reserve Assets. We are exposed to market risk associated with cash held on behalf of our merchants related to our payment processing services. As of March 31, 2024 and December 31, 2023, we had $193.0 million and $274.7 million, respectively, of cash collected on behalf of our merchants. The cash is held in accounts with various major financial institutions in the U.S. and Canada in an amount equal to at least 100% of the aggregate amount owed to our merchants. These balances can significantly fluctuate between periods due to activity at the end of the period and the day in which the period ends. Certain settlement assets are swept into overnight money market accounts on a daily basis.

Long-Term Debt. The fair value of our convertible debt is exposed to market risk. We do not carry our convertible debt at fair value but present the fair value for disclosure purposes (see Note 2 to our Financial Statements). Generally, the fair value of our convertible debt is impacted by changes in interest rates and changes in the price and volatility of our common stock. As of March 31, 2024, the fair value of the 2023 Convertible Notes was estimated at $420.9 million, using quoted market prices.

Foreign Currency Exchange Rate Risk

Due to foreign operations around the world, our financial statements are exposed to foreign currency exchange risk due to the fluctuations in the value of currencies in which we conduct business. Our principal currency exposures include the British Pound, Euro, Australian Dollar, Saudi Riyal, and South African Rand. While we attempt to maximize natural hedges by incurring expenses in the same currency in which we contract revenue, the related expenses for that revenue could be in one or more differing currencies than the revenue stream. In particular, if the U.S. Dollar were to strengthen it would reduce the reported amount of our foreign-denominated cash, cash equivalents, trade receivables, total revenues and total expenses that we translate into U.S. Dollars and report in our consolidated financial statements for, and as of the end of, each reporting period.

During the first quarter of 2024, we generated approximately 89% of our revenue in U.S. dollars. We expect that, in the foreseeable future, we will continue to generate a very large percentage of our revenue in U.S. dollars.

We have analyzed our foreign currency exposure as of March 31, 2024. A hypothetical adverse change of 10% in the March 31, 2024 exchange rates would not have had a material impact upon our results of operations.

Item 4. Controls and Procedures

(a) Disclosure Controls and Procedures

As required by Rule 13a-15(b), our management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), conducted an evaluation as of the end of the period covered by this report of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e). Based on that evaluation, the CEO and CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

(b) Internal Control Over Financial Reporting

As required by Rule 13a-15(d), our management, including the CEO and CFO, also conducted an evaluation of our internal control over financial reporting, as defined by Rule 13a-15(f), to determine whether any changes occurred during the quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, the CEO and CFO concluded that there has been no such change during the quarter covered by this report.
