NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. GENERAL

We have prepared the accompanying unaudited condensed consolidated financial statements as of March 31, 2023 and December 31, 2022, and for the quarters ended March 31, 2023 and 2022, 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, 2022 (our “2022 10-K”), filed with the SEC. The results of operations for the quarter ended March 31, 2023 are not necessarily indicative of the expected results for the entire year ending December 31, 2023.

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.

Reclassifications. Certain amounts within our net cash provided by operating activities on our Statement of Cash Flows for the first quarter of 2022 have been reclassified to conform to the March 31, 2023 presentation.

Revenue. The majority of our future revenue is related to our revenue management solution 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 2023 through 2036. Our customer contracts may include guaranteed minimums and fixed monthly or annual fees. As of March 31, 2023, our aggregate amount of the transaction price allocated to the remaining performance obligations is $1.6 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 approximately 75% of this amount by the end of 2025, with the remaining amount recognized by the end of 2036. We have excluded variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied from this amount.

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, 2023 and 2022 were as follows (in thousands):

	Quarter Ended
	March 31, 2023		March 31, 2022
SaaS and related solutions	$	257,876	$	234,977
Software and services		30,891		18,436
Maintenance		9,972		10,987
Total revenue	$	298,739	$	264,400

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, 2023 and 2022, as a percentage of our total revenue, were as follows:

	Quarter Ended
	March 31, 2023			March 31, 2022
Americas (principally the U.S.)		84	%		84	%
Europe, Middle East, and Africa		12	%		12	%
Asia Pacific		4	%		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 industry markets including retail, healthcare, financial services, insurance, and government entities. Revenue by customer vertical for the quarters ended March 31, 2023 and 2022, as a percentage of our total revenue, were as follows:

	Quarter Ended
	March 31, 2023			March 31, 2022
Broadband/Cable/Satellite		52	%		54	%
Telecommunications		20	%		19	%
Other		28	%		27	%
Total revenue		100	%		100	%

Deferred revenue recognized during the quarters ended March 31, 2023 and 2022 was $20.2 million and $28.0 million, respectively.

Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less at the date of the purchase to be cash equivalents. As of March 31, 2023 and December 31, 2022, our cash equivalents consist primarily of institutional money market funds, commercial paper, 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 March 31, 2023 and December 31, 2022, we had $0.9 million and $1.0 million, respectively, of restricted cash that serves to collateralize bank guarantees and outstanding letters of credit included in cash and cash equivalents in our unaudited Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”).

Short-term Investments. Our short-term investments as of March 31, 2023 and December 31, 2022 were zero and $0.1 million, respectively. Primarily all short-term investments held by us have contractual maturities of less than two years from the time of acquisition. Our short-term investments as of December 31, 2022 consisted of fixed income securities. Proceeds from the sale/maturity of short-term investments for the first quarters of 2023 and 2022 were $0.1 million and $21.9 million, respectively.

Settlement and Merchant Reserve Assets and Liabilities. Settlement assets and settlement liabilities represent cash collected on behalf of merchants via payment 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 would be against us, for payment. 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 payment 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 provide 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 and are fully 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, 2023				December 31, 2022
	Assets		Liabilities		Assets		Liabilities
Settlement assets/liabilities	$	155,418	$	154,444	$	219,368	$	218,525
Merchant reserve assets/liabilities		21,882		21,885		19,285		19,285
Total	$	177,300	$	176,329	$	238,653	$	237,810

Financial Instruments. Our financial instruments as of March 31, 2023 and December 31, 2022 include cash and cash equivalents, short-term investments, 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.

Our short-term investments and certain of our cash equivalents are considered “available-for-sale” and are reported at fair value in our Balance Sheets, with unrealized gains and losses, net of the related income tax effect, excluded from earnings and reported in a separate component of stockholders’ equity. Realized and unrealized gains and losses were not material in any period presented.

The following table represents the fair value hierarchy based upon three levels of inputs, of which Levels 1 and 2 are considered observable and Level 3 is unobservable, for our financial assets measured at fair value (in thousands):

4. DEBT

Our long-term debt, as of March 31, 2023 and December 31, 2022, was as follows (in thousands):

	March 31, 2023			December 31, 2022
2021 Credit Agreement:
2021 Term Loan, due September 2026, interest at adjusted LIBOR plus     applicable margin (combined rate of 6.784% at March 31, 2023)	$	138,750		$	140,625
Less – deferred financing costs		(2,469	)		(2,656	)
2021 Term Loan, net of unamortized discounts		136,281			137,969
$450 million revolving loan facility, due September 2026, interest at adjusted     LIBOR plus applicable margin (combined weighted-average rate of 6.756% at     March 31, 2023)		305,000			275,000
Total debt, net of unamortized discounts		441,281			412,969
Current portion of long-term debt, net of unamortized discounts		(37,500	)		(37,500	)
Long-term debt, net of unamortized discounts	$	403,781		$	375,469

2021 Credit Agreement. During the quarter ended March 31, 2023, 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, 2023 we had borrowed $305.0 million from our $450.0 million aggregate principal five-year revolving loan facility (the “2021 Revolver”), leaving us with $145.0 million available.

As of March 31, 2023, the interest rate on our 2021 Term Loan was 6.784% (adjusted LIBOR plus 1.625% per annum), the interest rates on our 2021 Revolver range from 6.385% to 6.784% (adjusted LIBOR plus 1.625% per annum), and our commitment fee on the unused $145.0 million was 0.20%.

The interest rates under the 2021 Credit Agreement are based upon our choice of an adjusted LIBOR 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, depending on 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 dependent upon our then-net secured total leverage ratio.

In April 2023, we entered into the First Amendment to the 2021 Credit Agreement (the “First Amendment”). The First Amendment replaces the interest rate benchmark, from LIBOR to the Secured Overnight Financing Rate ("SOFR"), and all references to “Eurodollar Borrowing(s)” or “Eurodollar Loans” have been replaced with “Term SOFR Borrowing(s)” or “Term SOFR Loans”. Any loan amounts outstanding at the effective date of the First Amendment, will continue to bear interest at the LIBOR rate, discussed above, until the end of the current interest election period applicable to such loan.

5. ACQUISITIONS

Keydok, LLC. On September 14, 2021, we acquired Keydok, a digital identity and document management platform provider, headquartered in Mexico. In March 2023, we decided to dissolve the Keydok business. See Note 6 for additional discussion.

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 escrowed funds of approximately $2 million to be paid through the first quarter of 2025, subject to certain reductions, as applicable. As of March 31, 2023, $0.3 million of the escrowed funds had been paid.

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. During 2022, $0.3 million of the earn-out had been achieved and was paid out in March 2023.

6. RESTRUCTURING AND REORGANIZATION CHARGES

During the first quarters of 2023 and 2022, we recorded restructuring and reorganization charges of $5.2 million and $13.1 million, respectively.

During the first quarter of 2023 we implemented the following restructuring and reorganizational activities:

•In March 2023 we decided to dissolve the Keydok business, which we had acquired in September of 2021. As a result, we recorded net impairment charges of $1.2 million, to include the write-off of the acquired goodwill. We also subsequently terminated approximately 30 Mexico-based employees, which resulted in restructuring charges related to involuntary terminations of $1.6 million.

•We reduced our workforce by approximately 30 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 $1.0 million.

•We recorded $0.4 million of additional operating lease right-of-use asset impairments on three of our leased real estate locations.

The activity in the restructuring and reorganization reserves during the first quarter of 2023 was as follows (in thousands):

	Termination Benefits			Other			Total
January 1, 2023, balance	$	2,491		$	-		$	2,491
Charged to expense during period		2,557			2,637			5,194
Cash payments		(2,751	)		(1,006	)		(3,757	)
Adjustment for asset impairment		-			(1,595	)		(1,595	)
Adjustment for accelerated depreciation		-			(36	)		(36	)
Other		351			-			351
March 31, 2023, balance	$	2,648		$	-		$	2,648

As of March 31, 2023, all 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, performance bonds, or standby letters of credit. As of March 31, 2023, we had $1.6 million of restricted assets used to collateralize these guarantees, with $0.9 million included in cash and cash equivalents and $0.7 million included in other non-current assets.

We have performance guarantees in the form of surety bonds and money transmitter bonds, both issued through a third-party that are not required to be on our Balance Sheet. As of March 31, 2023, we had performance guarantees of $3.5 million. 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, 2023, we had total aggregate money transmitter bonds of $19.0 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.

13

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 platform availability and timeliness of service delivery. As of March 31, 2023, 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, 2023. 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 the common shares is included in the following table (in thousands):

	Quarter Ended
	March 31,
	2023		2022
Basic weighted-average common shares		30,418		31,416
Dilutive effect of restricted common stock		191		394
Diluted weighted-average common shares		30,609		31,810

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 antidilutive, 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.

14

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”). We did not make any share repurchases during the first quarter of 2023. During the first quarter of 2022 we repurchased approximately 266,000 shares of our common stock for $16.0 million (weighted-average price of $60.13 per share) under a SEC Rule 10b5-1 Plan.

As of March 31, 2023, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 2.1 million shares.

Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the first quarters of 2023 and 2022, we repurchased and then cancelled approximately 166,000 shares of common stock for $9.3 million and approximately 123,000 shares of common stock for $7.8 million, respectively, 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 2023, our Board approved a quarterly cash dividend of $0.28 per share of common stock, totaling $8.8 million. During the first quarter of 2022, our Board approved a quarterly cash dividend of $0.265 per share of common stock, totaling $8.6 million.

Warrants. In 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, 2023, 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. A summary of our unvested restricted common stock activity during the quarter ended March 31, 2023 is as follows (shares in thousands):

	Quarter Ended
	March 31, 2023
	Shares			Weighted- Average Grant Date Fair Value
Unvested awards, beginning		1,147		$	53.34
Awards granted		600			52.01
Awards forfeited/cancelled		(19	)		54.51
Awards vested		(438	)		49.76
Unvested awards, ending		1,290		$	53.80

Included in the awards granted during the first quarter of 2023 are awards issued to members of executive management and certain key employees in the form of: (i) performance-based awards of approximately 134,000 restricted common stock shares, which vest in the first quarter of 2025 upon meeting certain pre-established financial performance objectives over a two-year performance period; and (ii) market-based awards of approximately 45,000 restricted common stock shares, which vest in the first quarter of 2026 upon meeting a relative total shareholder return performance achievement tier. Certain of these awards become fully vested upon a change in control, as defined, and the subsequent involuntary termination of employment.

The other restricted common stock shares granted during the first quarter of 2023 are primarily time-based awards, which vest annually over three years with no restrictions other than the passage of time. Certain shares of the restricted common stock become fully vested upon a change in control, as defined, involuntary terminations of employment, or death.

We recorded stock-based compensation expense for the first quarters of 2023 and 2022 of $6.4 million and $5.6 million, respectively.

Management Overview of Quarterly Results

First Quarter Highlights. A summary of our results of operations for the first quarter of 2023, when compared to the first quarter of 2022, is as follows (in thousands, except per share amounts and percentages):

	Quarter Ended
	March 31, 2023			March 31, 2022
Revenue	$	298,739		$	264,400
Transaction fees (1)		21,973			18,038
Operating Results:
Operating income	$	38,193		$	16,415
Operating income margin		12.8	%		6.2	%
Diluted EPS	$	0.68		$	0.19
Supplemental Data:
Restructuring and reorganization charges (2)	$	5,194		$	13,106
Executive transition costs		-			1,275
Acquisition-related costs:
Amortization of acquired intangible assets		3,209			3,656
Transaction-related costs		158			13
Stock-based compensation (2)		6,757			5,721
Loss on derivative liability upon debt conversion		-			7,456

(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 2023 was $298.7 million, a 13.0% increase when compared to revenue of $264.4 million for the first quarter of 2022. The increase can be primarily attributed to an increase in software and services revenue, due mainly to the timing of the closure of deals, as well as increased payment volumes, conversion of customer accounts onto our solutions, and other ancillary services.

Operating Results. Operating income for the first quarter of 2023 was $38.2 million, or a 12.8% operating margin percentage, compared to $16.4 million, or a 6.2% operating margin percentage for the first quarter of 2022. The increase in operating income can be mainly attributed to the higher revenue generated in the first quarter of 2023, discussed above, and to a lesser extent, the $7.9 million decrease in restructuring and reorganization charges between years.

Diluted EPS. Diluted EPS for the first quarter of 2023 was $0.68 compared to $0.19 for the first quarter of 2022, with the increase mainly attributed to the higher operating income in the first quarter of 2023, discussed above, and a $7.5 million loss on a derivative liability incurred in the first quarter of 2022 upon conversion of our 2016 Convertible Notes.

Cash and Cash Flows. As of March 31, 2023, we had cash, cash equivalents, and short-term investments of $167.7 million, as compared to $150.4 million as of December 31, 2022. Our cash flows provided by operating activities for the first quarter of 2023 were $15.4 million. See the Liquidity section below for further discussion of our cash flows.

17

Significant Customer Relationships

Customer Concentration. A large percentage of our historical revenue has been generated from our two largest customers, which are Charter Communications Inc. (“Charter”) and Comcast.

Revenue from these customers for the indicated periods was as follows (in thousands, except percentages):

	Quarter Ended
	March 31, 2023					December 31, 2022					March 31, 2022
	Amount		% of Revenue			Amount		% of Revenue			Amount		% of Revenue
Charter	$	61,532		21	%	$	58,006		20	%	$	52,069		20	%
Comcast		53,415		18	%		55,383		19	%		52,524		20	%

During the first quarter of 2023 we completed the final conversions of Charter's customer accounts onto our platforms, completing the consolidation of their residential and small and medium business internet, video, and landline voice customers that began in late 2021.

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

	As of
	March 31, 2023			December 31, 2022			March 31, 2022
Charter		22	%		22	%		20	%
Comcast		19	%		17	%		20	%

See our 2022 10-K for additional discussion of our business relationships and contractual terms with Charter and Comcast.

Charter. In April 2023, we entered into an Amended and Restated CSG Master Subscriber Management System Agreement (the “Agreement”) with Charter. The primary purpose of the Agreement was to consolidate the previous agreement and amendments into one document. The Agreement also formalizes the extension of the term through March 31, 2028, from December 31, 2027, as was contemplated in the previous agreement, in connection with the final conversion of Charter’s customer accounts, discussed above. The Agreement continues to provide that the term will automatically be extended for an additional one-year term, subject to Charter achieving certain conditional processing minimums on July 1, 2027, unless Charter provides us with written notice of non-renewal. All other material terms, provisions, and conditions of the previous agreement remain unchanged.

A copy of the Agreement, with confidential information redacted, will be filed with the SEC as an exhibit to our Form 10-Q for the period ended June 30, 2023.

Risk of Customer Concentration. We expect to continue to generate a significant percentage of our future revenue from our largest 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 significant financial or operating difficulties, it could have a material adverse effect on our financial condition 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 2022 10-K.

Results of Operations

Revenue. Total revenue for the first quarter of 2023 was $298.7 million, a 13.0% increase when compared to $264.4 million for the first quarter of 2022. During the first quarter of 2023, our software and services revenue increased $12.5 million, or 67.6% over the first quarter of 2022, primarily due to the timing of the closure of software license upgrades. Additionally, we saw continued year-over-year growth in our SaaS and related solutions revenue driven mainly by increased payments volumes, conversion of customer accounts onto our solutions, and other ancillary services, to include a strong quarter from our communication design and delivery centers. In the first quarter of 2023, we completed the final conversions of Charter's customer accounts onto our platforms, converting over nine million customer accounts in the past twelve months and more than fourteen million in total.

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 2023 and 2022 was as follows (in thousands):

	Quarter Ended
	March 31, 2023		March 31, 2022
Americas (principally the U.S.)	$	250,976	$	222,960
Europe, Middle East, and Africa		36,673		31,561

Total revenue	$	298,739	$	264,400

Total Operating Expenses. Total operating expenses for the first quarter of 2023 were $260.5 million, a 5.1% increase when compared to $248.0 million for the first quarter of 2022. The increase in total operating expenses is reflective of the higher revenue between periods, to include increased employee-related costs, offset to a certain degree by the $7.9 million 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 2023 was $155.0 million, a 12.0% increase when compared to $138.4 million for the first quarter of 2022. The increase in cost of revenue between periods is reflective of the increase in revenue year-over-year. Total cost of revenue as a percentage of revenue for the first quarters of 2023 and 2022 was 51.9% and 52.4%, respectively.

R&D Expense (Exclusive of Depreciation). R&D expense for the first quarter of 2023 was $35.5 million, a 7.5% increase when compared to $33.0 million for the first quarter of 2022, with the increase mainly attributed to higher employee-related costs. As a percentage of total revenue, R&D expense for the first quarters of 2023 and 2022 was 11.9% and 12.5%, respectively.

Our R&D efforts are focused on the continued evolution of our solutions that enable our customers worldwide to provide a more personalized experience while introducing new digital solutions. This includes the continued investment in our products and integration of acquired assets into our solutions.

Selling, General, and Administrative ("SG&A") Expense (Exclusive of Depreciation). SG&A expense for the first quarter of 2023 was $59.1 million, a 3.1% increase when compared to $57.3 million for the first quarter of 2022. This increase in SG&A expense is primarily attributed to increases in employee-related costs, to include incentive compensation; offset to a certain degree by lower building related costs due to our office closures in 2022. Our SG&A costs as a percentage of total revenue for the first quarters of 2023 and 2022 were 19.8% and 21.7%, respectively.

Restructuring and Reorganization Charges. Restructuring and reorganization charges for the first quarter of 2023 were $5.2 million, a $7.9 million decrease when compared to $13.1 million for the first quarter of 2022. The restructuring and reorganization charges for the first quarter of 2023 relate mainly to the following:

•net impairment charges of $1.2 million recorded related to the dissolution of the Keydok business;

•reduction in workforce resulting in restructuring charges related to involuntary terminations of $2.6 million; and

•real estate restructuring charges to include impairment charges of $0.4 million, as we continue to rationalize our real estate footprint to reflect our flexible work approach.

See Note 6 to our Financial Statements for additional discussion.

Operating Income. Operating income for the first quarter of 2023 was $38.2 million, or 12.8% of total revenue, compared to $16.4 million, or 6.2% of total revenue for the first quarter of 2022. The increase in operating income can be mainly attributed to the higher revenue generated in the first quarter of 2023, discussed above, and to a lesser extent, the $7.9 million decrease in restructuring and reorganization charges between years.

19

Interest Expense. Our interest expense relates primarily to our 2021 Credit Agreement. Interest expense for the first quarter of 2023 was $7.2 million, a $3.9 million increase when compared to $3.3 million for the first quarter of 2022, with the increase due to rising interest rates and a higher average outstanding debt balance during the first quarter of 2023.

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

Loss on Derivative Liability Upon Debt Conversion. In March 2022, we settled our 2016 Convertible Notes for approximately $242 million in cash. As a result of the conversion of the 2016 Convertible Notes, we recognized a $7.5 million loss on a derivative liability related to the change in our stock price over the observation period prior to settlement.

Other, net. Other, net for the first quarter of 2023 was $2.4 million of other expense, a $3.2 million change when compared to $0.8 million of other income for the first quarter of 2022, with the change primarily attributed to foreign currency movements.

Income Tax Provision. The effective income tax rates for the first quarters of 2023 and 2022 were as follows:

Quarter Ended
March 31, 2023			March 31, 2022
	28	%		8	%

Our estimated full year 2023 effective income tax rate is approximately 29%, a slight increase when compared to our 2022 full year rate of approximately 28%.

The first quarter of 2022 effective income tax rate was impacted by the combination of lower net income for the quarter and a discrete tax benefit related to the vesting of restricted common stock during the quarter.

Liquidity

Cash and Liquidity. As of March 31, 2023, our principal sources of liquidity included cash, cash equivalents, and short-term investments of $167.7 million, compared to $150.4 million as of December 31, 2022. We generally invest our excess cash balances in low-risk, short-term investments to limit our exposure to market and credit risks.

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. As of March 31, 2023, we had $305.0 million outstanding on the 2021 Revolver, leaving $145.0 million available to us. The 2021 Credit Agreement contains customary affirmative, negative, and financial covenants. As of March 31, 2023, and the date of this filing, we believe that we are in compliance with the provisions of the 2021 Credit Agreement.

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

	March 31, 2023		December 31, 2022
Americas (principally the U.S.)	$	110,319	$	91,569
Europe, Middle East and Africa		45,146		49,099
Asia Pacific		12,216		9,768
Total cash, equivalents, and short-term investments	$	167,681	$	150,436

20

We generally have ready access to substantially all of our cash, cash equivalents, and short-term investment balances, 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, 2023, we had $0.9 million of cash restricted as to use primarily to collateralize guarantees and outstanding letters of credit included in our total cash, cash equivalents, and short-term investments balance. In addition, as of March 31, 2023, we had $177.3 million 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, gains/losses on items such as investments and debt extinguishments/conversions, unrealized foreign currency gain/losses, deferred income taxes, stock-based compensation, etc.), and then factoring in the impact of changes in operating assets and liabilities. See our 2022 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):

						Net Cash
			Changes in			Provided by
			Operating			(Used In) Operating
			Assets and			Activities –
	Operations		Liabilities			Totals
Cash Flows from Operating Activities:
2023:
March 31 (1)	$	50,158	$	(34,761	)		15,397
2022:
March 31 (1)	$	49,687	$	(55,236	)	$	(5,549	)

(1)Cash flows from operating activities for the first quarters of 2023 and 2022 reflect the impact of the payment of the 2022 and 2021 year-end accrued employee incentive compensation in the first quarter subsequent to the year-end accrual for these items.

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 and changes in accrued expenses), and generally over longer periods of time, do not significantly impact our cash flows from operations.

Significant fluctuations in key operating assets and liabilities between 2023 and 2022 that impacted our cash flows from operating activities are as follows:

Billed Trade Accounts Receivable

Management of our billed accounts receivable is one of the primary factors in maintaining strong cash flows from operating activities. Our billed trade accounts receivable balance includes 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 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 doubtful accounts receivable (“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
2023:
March 31	$	261,028	$	(5,254	)	$	255,774		68
2022:
March 31	$	243,292	$	(4,924	)	$	238,368		70

As of March 31, 2023 and 2022, approximately 95% and 94%, respectively, of our billed accounts receivable balance were less than 60 days past due.

21

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 any 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 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 transactions. For example, our ability to invoice and collect arrangement fees may be 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; (iii) the overall project status in certain situations in which we act as a subcontractor to another vendor on a project; or (iv) due to currency controls in certain foreign jurisdictions.

Unbilled Trade Accounts Receivable

Unbilled trade accounts receivable increased $20.5 million to $73.3 million as of March 31, 2023, from $52.8 million as of December 31, 2022, due primarily to large implementation projects where various milestone and contractual billing dates have not yet been reached or delayed. Unbilled accounts receivable are an inherent characteristic of certain software and services transactions and may fluctuate between quarters, as these type of transactions typically have scheduled invoicing terms over several quarters, as well as certain milestone billing events.

Accrued Employee Compensation

Accrued employee compensation decreased $18.5 million to $49.8 million as of March 31, 2023, from $68.3 million as of December 31, 2022, due primarily to the payment of the 2022 employee incentive compensation during the first quarter of 2023 that was fully accrued at December 31, 2022.

Cash Flows from Investing Activities. Our typical investing activities consist of purchases/sales of short-term investments and purchases of software, property and equipment, which are discussed below.

Purchases/Sales of Short-Term Investments

During the first quarters of 2023 and 2022, we sold (or had mature) $0.1 million and $21.9 million, respectively, of short-term investments. We continually evaluate the appropriate mix of our investment of excess cash balances between cash equivalents and short-term investments in order to maximize our investment returns and liquidity.

Purchases of Software, Property and Equipment

Our capital expenditures for the first quarters of 2023 and 2022 for software, property and equipment were $8.7 million and $10.4 million, respectively, and consisted principally of investments in: (i) communication design and delivery center equipment and infrastructure; (ii) software and related equipment; and (iii) computer hardware.

Cash Flows from Financing Activities. Our financing activities typically consist of activities associated with our common stock, long-term debt, and settlement and merchant reserve activity.

Cash Dividends Paid on Common Stock

During the first quarters of 2023 and 2022, the Board approved dividends totaling $8.8 million and $8.6 million, respectively, and made dividend payments of $9.1 million and $8.9 million, respectively, through March 31, 2023 and 2022, with the differences between the amount approved and paid attributed to dividends on accrued unvested incentive shares that are paid upon vesting and previously approved.

Repurchase of Common Stock

During the first quarters of 2023 and 2022, we repurchased zero and approximately 266,000 shares of our common stock, respectively, under the guidelines of our Stock Repurchase Program for zero and $16.0 million, respectively.

Outside of our Stock Repurchase Program, during the first quarters of 2023 and 2022, we repurchased from our employees and then cancelled approximately 166,000 and 123,000 shares of our common stock, respectively, for $9.3 million and $7.8 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans.

Through the first quarters of 2023 and 2022, we have paid $9.3 million and $23.7 million, respectively, for our total repurchases of common stock, with the differences when compared to the amounts purchased attributed to the timing of the settlement.

22

Long-term Debt

During the first quarters of 2023 and 2022, we made principal repayments on our 2021 Term Debt of $1.9 million for both periods. Additionally, during the first quarter of 2023, we borrowed $30.0 million from our 2021 Revolver for general corporate purposes and during the first quarter of 2022, we borrowed $245.0 million from our 2021 Revolver to settle our 2016 Convertible Notes for $242.3 million.

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 2023 and 2022, we had net settlement and merchant reserve activity of $61.5 million and $23.5 million, respectively, related to the cash collected, held on behalf, and paid to our merchants related to our payment processing services and the net change in deposits held on behalf of our merchants.

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, bid bonds, and performance bonds. 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 operation, liquidity, capital expenditures, or capital resources. See Note 7 to our Financial Statements for additional information on these guarantees.

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, Cash Equivalents, and Short-term Investments. As of March 31, 2023, we had cash, cash equivalents, and short-term investments of $167.7 million, of which approximately 61% is in U.S. dollars and held in the U.S. Included in cash and cash equivalents is $0.9 million of restricted cash. 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, our 2021 Revolver. As of March 31, 2023, we had $305.0 million outstanding on our 2021 Revolver and had the remaining $145.0 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, 2023, we had 2.1 million shares 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 2023, we did not repurchase any of our common stock under our Stock Repurchase Program.

23

Outside of our Stock Repurchase Program, during the first quarter of 2023, we repurchased from our employees and then cancelled approximately 166,000 shares of our common stock for $9.3 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 2023, the Board declared dividends totaling $8.8 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 acquisition activity, we have the following potential future obligations:

oThe 2021 Kitewheel, LLC purchase acquisition agreement includes deferred purchase price payments, with the remaining $4.0 million to be paid in equal annual amounts on July 1, 2023 and 2024.

oThe 2021 DGIT acquisition purchase price includes escrowed funds of approximately $2 million to be paid through the first quarter of 2025, subject to certain reductions, as applicable. In 2022 we made escrowed payments of $0.3 million.

Additionally, there are provisions for up to approximately $13 million of potential future earn-out payments through September 30, 2025. During the first quarter of 2023 we made an earn-out payment of $0.3 million.

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.

•Capital Expenditures. During the first quarter of 2023, we spent $8.7 million on capital expenditures.

•Stock Warrants. In 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, 2023, 1.0 million stock warrants remain issued, none of which are vested.

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

•Long-Term Debt. As of March 31, 2023, our long-term debt consisted of our 2021 Credit Agreement which includes: (i) outstanding 2021 Term Loan borrowings of $138.8 million; and (ii) outstanding 2021 Revolver borrowings of $305.0 million.

Our 2021 Credit Agreement mandatory repayments 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 (assuming no further amounts are borrowed, and the amount is not voluntarily repaid) are $9.4 million and $21.0 million, respectively. 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 also believe we could obtain additional capital through other debt sources which may be available to us if deemed appropriate.

24

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, 2023, we are exposed to various market risks, including changes in interest rates, fluctuations and changes in the market value of our cash equivalents and short-term investments 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 current interest rates on our 2021 Credit Agreement are based upon an adjusted LIBOR rate plus an applicable margin, or an ABR plus an applicable margin. In April 2023, we amended the 2021 Credit Agreement to replace the LIBOR rate with the SOFR rate for interest periods entered into after the effective date of amendment. 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, 2023 adjusted LIBOR rate would not have a material impact upon our results of operations.

Market Risk

Cash Equivalents and Short-Term Investments. Our cash and cash equivalents as of March 31, 2023 and December 31, 2022 were $167.7 million and $150.4 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 and short-term investments. 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.

Our short-term investments as of March 31, 2023 and December 31, 2022 were zero and $0.1 million, respectively. Currently, we utilize short-term investments as a means to invest our excess cash only in the U.S. The day-to-day management of our short-term investments is performed by a large financial institution in the U.S., using strict and formal investment guidelines approved by our Board. Under these guidelines, short-term investments are limited to certain acceptable investments with: (i) a maximum maturity; (ii) a maximum concentration and diversification; and (iii) a minimum acceptable credit quality. At this time, we believe we have minimal liquidity risk associated with the short-term investments included in our portfolio.

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, 2023 and December 31, 2022, we had $177.3 million and $238.7 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.

Foreign Currency Exchange Rate Risk

Due to foreign operations around the world, our balance sheet and income statement are exposed to foreign currency exchange risk due to the fluctuations in the value of currencies in which we conduct business. 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.

During the first quarter of 2023, we generated approximately 86% 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.

As of March 31, 2023 and December 31, 2022, the carrying amounts of our monetary assets and monetary liabilities on the books of our non-U.S. subsidiaries in currencies denominated in a currency other than the functional currency of those non-U.S. subsidiaries are as follows (in thousands, in U.S. dollar equivalents):

	March 31, 2023					December 31, 2022
	Monetary			Monetary		Monetary			Monetary
	Liabilities			Assets		Liabilities			Assets
Pounds sterling	$	(2	)	$	669	$	(119	)	$	601
Euro		(595	)		5,148		(425	)		1,992
U.S. Dollar		(1,312	)		33,312		(597	)		31,646
Other		(40	)		929		(72	)		503
Totals	$	(1,949	)	$	40,058	$	(1,213	)	$	34,742

A hypothetical adverse change of 10% in the March 31, 2023 exchange rates would not have had a material impact upon our results of operations.

25

Item 4. Controls and Procedures

(a) Disclosure Controls and Procedures
