Results of Operations

Revenues: Total revenues for the third quarter 2013 were $186.2 million, a 2% decrease when compared to revenues of $190.0 million for the third quarter of 2012, and relatively consistent when compared to the $186.1 million reported for the second quarter of 2013. The year-over-year decrease can be attributed primarily to the impact of the Comcast and Time Warner pricing adjustments that were effective in 2013.

Non-GAAP Results: Non-GAAP operating income for the third quarter of 2013 was $29.4 million, or 15.8% of total revenues, compared to $31.1 million, or 16.4%, for the third quarter of 2012. Non-GAAP operating income for the second quarter of 2013 was $30.4 million, or 16.3% of total revenues. The year-over-year decrease in operating income and operating income margin reflects the impact of the Comcast and Time Warner pricing adjustments that were effective in 2013.

Non-GAAP EPS for the third quarter of 2013 was $0.52, compared to non-GAAP EPS of $0.50 for the third quarter of 2012. Non-GAAP EPS for the second quarter of 2013 was $0.57.

GAAP Results: GAAP operating income for the third quarter of 2013 was $20.6 million, or 11.0% of total revenues, compared to $21.7 million, or 11.4%, for the same period in 2012.

GAAP EPS for the third quarter of 2013 was $0.47, compared to $0.29 for the third quarter of 2012, with the increase primarily related to an unusually low GAAP effective income tax rate for the current quarter of 8%. This third quarter income tax rate benefited primarily from the recognition of incremental R&D income tax credits claimed for development activities from previous years, which provided a benefit of approximately $0.17 per diluted share for the third quarter of 2013.

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 Systems International, Inc.

October 29, 2013

Page 11

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 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 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 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, and facility consolidations and abandonments. 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 adjusted EBITDA as income before interest, income taxes, depreciation, amortization, stock-based compensation, foreign currency transaction adjustments, and unusual items, such as restructuring 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.

Non-GAAP income before income taxes (2)	$	80,118	$	1.58	$	91,340	$	1.66

(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 third quarter and nine months ended September 30, 2013, the estimated effective income tax rate for non-GAAP purposes was approximately 36% for both periods, and the weighted-average diluted shares outstanding were 32.7 million and 32.6 million, respectively.

For the third quarter and nine months ended September 30, 2013, the GAAP effective income tax rate was unusually low at approximately 8% and 14%, respectively, driven in part by incremental R&D income tax credits claimed for development activities from previous years. The lower tax rates provided a benefit of approximately $0.17 per diluted share for both the quarter and nine months ended September 30, 2013. These unusual tax benefits are excluded from our non-GAAP effective income tax rates for these same periods.

In addition to this, the rate for the nine months ended September 30, 2013 also benefited from the recognition of the 2012 R&D tax credits of approximately $0.18 per diluted share, that were recognized for GAAP purposes in the first quarter of 2013 since the credit legislation was passed by Congress in January 2013. The effective income tax rate for non-GAAP purposes of approximately 36% for the nine months ended September 30, 2013 excludes the impact of these 2012 tax credits, as they were reflected in the 2012 non-GAAP effective income tax rate.

(4) For both the third quarter and nine months ended September 30, 2012, the estimated effective income rate for non-GAAP purposes was approximately 41%, and the weighted-average diluted shares outstanding were 32.4 million.

Non-GAAP Financial Measures – 2013 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 2013 full year financial guidance, is as follows:

	2013 Guidance
GAAP operating income margin		11.0	%
Restructuring charges (7)		0.5	%
Stock-based compensation (8)		2.0	%
Amortization of acquired intangible assets (9)		2.5	%
Non-GAAP operating income margin (“approximately 16%”)		16.0	%

(7) This represents the pretax impact of restructuring charges of an estimated $4 million on CSG’s operating income margin as a percentage of the midpoint of 2013 revenue guidance.

(8) This represents the pretax impact of stock-based compensation expense of an estimated $16 million on CSG’s operating income margin as a percentage of the midpoint of 2013 revenue guidance.

(9) This represents the pretax impact of amortization of acquired intangible assets expense of an estimated $19 million on CSG’s operating income margin as a percentage of the midpoint of 2013 revenue guidance.

Non-GAAP EPS:

The reconciliation of GAAP EPS to non-GAAP EPS as included in CSG’s 2013 full year financial guidance is as follows (in thousands, except per share amounts):

	2013 Guidance Range
	Low Range				High Range
	Pretax Amount (10)		EPS (12)		Pretax Amount (10)		EPS (12)
GAAP income before income taxes	$	61,000	$	1.49	$	66,000	$	1.61

Stock-based compensation		16,000				16,000
Amortization of acquired intangible assets		19,000				19,000
Amortization of OID		5,000				5,000
Non-GAAP income before income taxes (11)	$	105,000	$	2.05	$	110,000	$	2.15

(10) 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.

(11) 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.

(12) For 2013, the estimated effective income tax rate for non-GAAP purposes is expected to be approximately 36%, and the weighted-average diluted shares outstanding are expected to be 32.8 million.

The GAAP effective income tax rate is expected to be approximately 20% for the year, driven in part by incremental R&D income tax credits claimed for development activities from previous years. The lower tax rate provides a benefit of approximately $0.17 per diluted share. These unusual tax benefits are excluded from our non-GAAP effective income tax rates for the year.

In addition to this, the GAAP effective income tax rate also benefited from the recognition of the 2012 R&D tax credits of approximately $0.18 per diluted share, that were recognized for GAAP purposes in the first quarter of 2013 since the credit legislation was passed by Congress in January 2013. The effective income tax rate for non-GAAP purposes of approximately 36% also excludes the impact of these 2012 tax credits, as they were reflected in the 2012 non-GAAP effective income tax rate.
