PRESS RELEASE

For Immediate Release

CSG Systems INTERNATIONAL reports results

for SECOND quarter 2015

ENGLEWOOD, COLO. (August 5, 2015) — CSG Systems International, Inc. (Nasdaq: CSGS), a leading global provider of interactive transaction-driven solutions and services, today reported results for the quarter ended June 30, 2015.

Key Highlights:

• Second quarter 2015 results:

• Total revenues were $182.6 million.

• Non-GAAP operating income was $34.9 million, or 19.1% of total revenues and GAAP operating income was $26.2 million, or 14.3% of total revenues.

• Non-GAAP earnings per diluted share (EPS) was $0.61. GAAP EPS was $0.39.

• Cash flows from operations for the quarter were $39.6 million.

• CSG paid its quarterly cash dividend of $0.175 per share of common stock, or a total of approximately $6 million,to shareholders.

“While we had a slower than expected start to the first half of the year, we continue to make progress on our longer-term initiatives as we migrate new accounts and clients to our solutions, which increases our recurring revenue base.  The scale benefits of growing our recurring revenues, and our attention to cost management, has allowed us to reach the low end of our long-term non-GAAP operating margin target of 18-20%,” said Peter Kalan, chief executive officer of CSG International. “We continue to generate strong cash flows enabling us to continue to invest in our business while continuing to return cash to our shareholders. This is a hallmark of our business.”

Results of Operations

Revenues: Total revenues for the second quarter of 2015 were $182.6 million, a 1% decrease when compared to revenues of $184.6 million for the second quarter of 2014, and a 2% decrease when compared to the $185.6 million for the first quarter of 2015. The year-over-year decrease in revenues can be attributed to foreign currency movements which had a negative impact of $3.8 million, while the sequential quarterly decline is mainly due to lower client discretionary spending on ancillary services.

Non-GAAP Results: Non-GAAP operating income for the second quarter of 2015 was $34.9 million, or 19.1% of total revenues, compared to $29.8 million, or 16.1%, for the second quarter of 2014. Non-GAAP operating income for the first quarter of 2015 was $30.8 million, or 16.6% of total revenues. Non-GAAP EPS for the second quarter of 2015 was $0.61, compared to non-GAAP EPS of $0.52 for the second quarter of 2014 and $0.51 for the first quarter of 2015. The year-over-year increases in operating income and non-GAAP EPS are due primarily to lower operating expenses (driven primarily by foreign currency movements and focus on cost management) and higher processing revenues, while the sequential quarterly increases can be mainly attributed to lower expenses in the second quarter.

GAAP Results: GAAP operating income for the second quarter of 2015 was $26.2 million, or 14.3% of total revenues, compared to $21.8 million, or 11.8%, for the same period in 2014.

GAAP EPS for the second quarter of 2015 was $0.39 compared to $0.28 for the second quarter of 2014.

DISCLOSURES FOR NON-GAAP FINANCIAL MEASURES

Use of Non-GAAP Financial Measures and Limitations

To supplement its condensed consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), CSG uses non-GAAP operating income, non-GAAP EPS, non-GAAP adjusted EBITDA, and non-GAAP free cash flow. CSG believes that these non-GAAP financial measures, when reviewed in conjunction with its GAAP financial measures, provide investors with greater transparency to the information used by CSG’s management in its financial and operational decision making. CSG uses these non-GAAP financial measures for the following purposes:

• Certain internal financial planning, reporting, and analysis;

• Forecasting and budgeting;

• Certain management compensation incentives; and

• Communications with CSG’s Board of Directors, stockholders, financial analysts, and investors.

These non-GAAP financial measures are provided with the intent of providing investors with the following information:

• A more complete understanding of CSG’s underlying operational results, trends, and cash generating capabilities;

• Consistency and comparability with CSG’s historical financial results; and

• Comparability to similar companies, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures are not measures of performance under GAAP, and therefore should not be considered in isolation or as a substitute for GAAP financial information. Limitations with the use of non-GAAP financial measures include the following items:

• Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles;

• The way in which CSG calculates non-GAAP financial measures may differ from the way in which other companies calculate similar non-GAAP financial measures;

• Non-GAAP financial measures do not include all items of income and expense that affect CSG’s operations and that are required by GAAP to be included in financial statements;

• Certain adjustments to CSG’s non-GAAP financial measures result in the exclusion of items that are recurring and will be reflected in CSG’s financial statements in future periods; and

• Certain charges excluded from CSG’s non-GAAP financial measures are cash expenses, and therefore do impact CSG’s cash position.

CSG compensates for these limitations by relying primarily on its GAAP results and using non-GAAP financial measures as a supplement only. Additionally, CSG provides specific information regarding the treatment of GAAP

CSG Systems International, Inc.

amounts considered in preparing the non-GAAP financial measures and reconciles each non-GAAP financial measure to the most directly comparable GAAP measure.

Non-GAAP Financial Measures: Basis of Presentation

The table below outlines the exclusions from CSG’s non-GAAP financial measures:

Non-GAAP Exclusions	Operating Income		EPS
Restructuring and reorganization charges		X		X
Acquisition-related charges		X		X
Stock-based compensation		X		X
Amortization of acquired intangible assets		X		X
Amortization of original issue discount (“OID”)		—		X
Unusual income tax matters		—		X

CSG believes that excluding certain items in calculating its non-GAAP financial measures provides meaningful supplemental information regarding CSG’s performance and these items are excluded for the following reasons:

• Restructuring and reorganization charges are infrequent expenses that result from cost reduction initiatives and/or significant changes to CSG’s business, to include such things as involuntary employee terminations, changes in management structure, divestitures of businesses, facility consolidations and abandonments, and fundamental reorganizations impacting operational focus and direction. These charges are not considered reflective of CSG’s recurring core business operating results. The exclusion of these items in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to compare CSG’s current financial results with historical and future periods.

• Acquisition-related charges relate to direct and incremental expenses related to business acquisitions, and thus, are not considered reflective of CSG’s recurring core business operating results. These charges typically include expenses related to legal, accounting, and other professional services. The exclusion of these charges in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to compare CSG’s current financial results with historical and future periods.

• Stock-based compensation results from CSG’s issuance of equity awards to its employees under incentive compensation programs. The amount of this incentive compensation in any period is not generally linked to the level of performance by employees or CSG, but instead is more dependent on CSG’s stock price at the date the equity award is granted, and the employee service period over which the equity awards vest. The exclusion of these expenses in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to evaluate the non-cash expense related to compensation included in CSG’s results of operations, and therefore, the exclusion of this item allows investors to further evaluate the cash generating capabilities of CSG’s business.

• Amortization of acquired intangible assets is the result of business acquisitions. A portion of the purchase price in an acquisition is allocated to acquired intangible assets (e.g., software, client relationships, etc.), which are then amortized to expense over their estimated useful lives. This annual amortization expense is generally unchanged from the initial estimates, regardless of performance of the acquired business in any one period. Also, the value assigned to acquired intangible assets in a business combination is based on various estimates and valuation techniques, and does not necessarily represent the costs CSG would incur to develop such capabilities internally. Additionally, amortization of acquired intangible assets can be inconsistent in amount and frequency, and can be significantly affected by the timing and size of an acquisition. The exclusion of these expenses in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to evaluate the non-cash expense related to acquisitions included in CSG’s results of operations, and therefore, the exclusion of this item allows investors to further evaluate the cash generating capabilities of CSG’s business.

• The convertible debt securities OID is the result of allocating a portion of the principal balance of the debt at issuance to the equity component of the instrument, as required under current accounting rules. This OID is then amortized to interest expense over the life of the respective convertible debt instrument. The interest expense related to the amortization of the OID is a non-cash expense, and therefore, the exclusion of this item allows investors to further evaluate the cash interest costs of CSG’s convertible debt securities for cash flow, liquidity, and debt service purposes.

• Unusual items within CSG’s quarterly and/or annual income tax expense can occur from such things as income tax accounting timing matters, income taxes related to unusual events, or as a result of different treatment of certain items for book accounting and income tax purposes. Consideration of such items in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to compare CSG’s current financial results with historical and future periods.

CSG also reports non-GAAP adjusted EBITDA and non-GAAP free cash flow. Management believes non-GAAP adjusted EBITDA is a useful measure to investors in evaluating CSG’s operating performance, liquidity, debt servicing capabilities, and enterprise valuation. CSG defines non-GAAP adjusted EBITDA as income before interest, income taxes, depreciation, amortization, stock-based compensation, foreign currency transaction adjustments, and unusual items, such as restructuring and reorganization charges, as discussed above. Additionally, management uses non-GAAP free cash flow, among other measures, to assess its financial performance and cash generating capabilities, and believes that it is useful to investors because it shows CSG’s cash available to service debt, make strategic acquisitions and investments, repurchase its common stock, pay cash dividends, and fund ongoing operations. CSG defines non-GAAP free cash flow as net cash flows from operating activities less the purchases of property and equipment.

(1) These items (on a pretax basis) are calculated in accordance with GAAP, and are reflected as part of the results of operations in the accompanying Unaudited Condensed Consolidated Statements of Income.

(2) Non-GAAP EPS is calculated by taking the non-GAAP income before income taxes and deducting from this amount non-GAAP income taxes calculated by using the non-GAAP effective income tax rate for the period, and then dividing the result of this calculation by the outstanding diluted shares for the period.

(3) For the second quarter and six months ended June 30, 2015, the GAAP effective income tax rate was 43%, the non-GAAP effective income tax rate was approximately 38%, and the outstanding diluted shares were 33.1 million and 33.2 million, respectively. The difference between the GAAP and the non-GAAP effective income tax rates relates primarily to the timing of the 2015 R&D tax credit legislation. The anticipated quarterly benefit of the credits is included for non-GAAP purposes, but cannot be reflected for GAAP purposes until the legislation is actually passed.

(4) For the second quarter and six months ended June 30, 2014, the GAAP effective income tax rate was 47% and 45%, respectively, the non-GAAP effective income tax rate was approximately 36% for both periods, and the outstanding diluted shares were 33.5 million and 33.8 million, respectively. The difference between the GAAP and the non-GAAP effective income tax rates relates primarily to the timing of the 2014 R&D tax credit legislation. The anticipated quarterly benefit of the credits is included for non-GAAP purposes, but cannot be reflected for GAAP purposes until the legislation is actually passed.

Non-GAAP Financial Measures – 2015 Financial Guidance

Non-GAAP Operating Income Margin:

The reconciliation of GAAP operating income margin to non-GAAP operating income margin, as included in CSG’s 2015 full year financial guidance, is as follows:

	2015 Guidance
GAAP operating income margin		13.5	%
Restructuring and reorganization charges		0.0	%
Stock-based compensation (7)		3.0	%
Amortization of acquired intangible assets (8)		1.5	%
Non-GAAP operating income margin (“approximately 18.0%”)		18.0	%

(7) This represents the pretax impact of stock-based compensation expense of an estimated $22 million on CSG’s operating income margin as a percentage of the midpoint of 2015 revenue guidance.

(8) This represents the pretax impact of amortization of acquired intangible assets expense of an estimated $12 million on CSG’s operating income margin as a percentage of the midpoint of 2015 revenue guidance.

Non-GAAP EPS:

The reconciliation of GAAP EPS to non-GAAP EPS as included in CSG’s 2015 full year financial guidance is as follows (in thousands, except per share amounts):

	2015 Guidance Range
	Low Range				High Range
	Pretax Amount (9)		EPS (11)		Pretax Amount (9)		EPS (11)
GAAP income before income taxes	$	83,000	$	1.43	$	87,000	$	1.49
Restructuring and reorganization charges		1,000				1,000
Stock-based compensation		22,000				22,000
Amortization of acquired intangible assets		12,000				12,000
Amortization of OID		6,000				6,000
Non-GAAP income before income taxes (10)	$	124,000	$	2.33	$	128,000	$	2.40

(9) These items (on a pretax basis) are calculated in accordance with GAAP, and will be reflected as part of the results of operations in CSG’s Unaudited Condensed Consolidated Statements of Income.

(10) Non-GAAP EPS is calculated by taking the non-GAAP income before income taxes and deducting from this amount non-GAAP income taxes calculated by using the non-GAAP effective income tax rate for the period, and then dividing the result of this calculation by the outstanding diluted shares for the period.

(11) For 2015, the estimated effective income tax rate for non-GAAP purposes is expected to be approximately 38%, which assumes Congress will approve the 2015 R&D income tax credit legislation prior to the end of 2015. The weighted-average diluted shares outstanding are expected to be 33.0 million.
