Results of Operations

Revenues: Total revenues for the fourth quarter of 2011 were $187.6 million, a 22% increase when compared to revenues of $154.1 million for the fourth quarter of 2010, and a 3% increase when compared to revenues of $182.8 million for the third quarter of 2011. Total revenues for the full year 2011 were $734.7 million, a 34% increase when compared to revenues of $549.4 million for full year 2010. The year-over-year increases can be attributed to the inclusion of a full quarter and year of financial results in 2011 from Intec Telecom, acquired on November 30, 2010, as compared to the inclusion of only one month for the quarter and year ended December 31, 2010.

Non-GAAP Results: Non-GAAP operating income for the fourth quarter of 2011 was $40.0 million, or 21.3% of total revenues, which compares to $36.4 million, or 23.7%, for the same period in 2010. Non-GAAP operating income for the third quarter of 2011 was $33.3 million, or 18.2% of total revenues. Non-GAAP operating income for the full year 2011 was $139.0 million, or 18.9% of total revenues, which compares to $125.6 million, or 22.9%, for the full year 2010. The lower operating margin percentages in 2011 are consistent with the company’s expectations as it reflects the lower margin profile of Intec’s global software and services business.

Non-GAAP EPS for the fourth quarter of 2011 was $0.64, compared to non-GAAP EPS of $0.69 for the fourth quarter of 2010. Non-GAAP EPS for the full year 2011 was $2.25, compared to non-GAAP EPS of $2.30 for the full year 2010.

GAAP Results: GAAP operating income for the fourth quarter of 2011 was $27.0 million, or 14.4% of total revenues, compared to $20.7 million, or 13.4%, for the same period in 2010. GAAP operating income for the full year 2011 was $96.3 million, or 13.1% of total revenues, compared to $74.3 million, or 13.5% for the full year 2010.

GAAP EPS for the fourth quarter of 2011 was $0.35, compared to a loss of ($0.05) for the fourth quarter of 2010.

Additionally, GAAP EPS for the fourth quarter of 2011, when compared to GAAP EPS for the fourth quarter of 2010, was impacted by the following items:

• an additional $3.1 million of amortization of acquired intangible assets related to the Intec acquisition, which negatively impacted GAAP EPS by $0.05 per diluted share; and

• restructuring charges of $4.9 million, which negatively impacted GAAP EPS by $0.08 per diluted share.

GAAP EPS for the full year 2011 was $1.28, compared to $0.67 for the full year 2010. GAAP EPS for 2011 and 2010 were impacted by the following items:

• the Intec acquisition-related charges of $26.2 million for the year ended December 31, 2010 negatively impacted 2010 GAAP EPS by $0.52 per diluted share;

• the data center transition expenses of $20.5 million for the year ended December 31, 2010 negatively impacted 2010 GAAP EPS by $0.40 per diluted share;

• the loss on the repurchase of convertible debt securities of $12.7 million for the year ended December 31, 2010 negatively impacted 2010 GAAP EPS by $ 0.25 per diluted share;

• restructuring charges of $7.9 million for the year ended December 31, 2011 negatively impacted 2011 GAAP EPS by $0.13 per diluted share; and

• an additional $17.4 million of amortization of acquired intangible assets related to the Intec acquisition negatively impacted 2011 GAAP EPS by $0.29 per diluted share.

Balance Sheet and Cash Flows

Balance Sheet: Certain key balance sheet items as of the end of the indicated periods are as follows (in thousands):

	December 31, 2011			September 30, 2011			December 31, 2010
Cash, cash equivalents, and short-term investments	$	158,830		$	138,599		$	215,550
Net billed trade accounts receivable (1)		179,804			157,276			155,005
Total long-term debt:
Par value	$	340,000		$	342,500		$	410,149
Unamortized OID		(30,256	)		(31,435	)		(35,462	)
Net debt carrying amount	$	309,744		$	311,065		$	374,687

(1) The increase in billed accounts receivable at December 31, 2011 can be primarily attributed to the fluctuations in the timing of client payments at quarter-end and to several billing milestones being met towards the end of the fourth quarter of 2011.

Cash Flows: Certain key operating cash flow items for the indicated quarters then ended are as follows (in thousands):

	Quarter Ended December 31,						Year Ended December 31,
	2011			2010			2011 (2)			2010
Cash Flows from Operating Activities:
Operations	$	34,348		$	32,529		$	130,337		$	112,262

(2) The decrease in cash flows related to operating assets and liabilities for the full year 2011 relates primarily to: (i) the change in the monthly invoice timing for DISH, which was included as part of its contract renewal terms in January 2011, which had a negative $20 million impact; (ii) an increase in accounts receivable at December 31, 2011, as discussed above; (iii) the timing of payments for several items specific to the first quarter of 2011, including approximately $8 million of Intec acquisition-related expenses and the 2010 employee incentive bonuses, both of which were accrued at December 31, 2010; and (iv) $6 million payment of deferred income tax liabilities that became due in 2011 as a result of the repurchase of our 2004 Convertible Debt Securities.

SUPPLEMENTAL REVENUE ANALYSIS

CSG Systems International acquired Intec Telecom Systems on November 30, 2010. Therefore, CSG included Intec’s financial results for one month in its full year results ended December 31, 2010, and for twelve months in its full year results ended December 31, 2011.

By integrating Intec’s significantly higher global revenue base, CSG increased its geographic revenue diversification and decreased its customer concentration, as illustrated in the tables below:

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 purposes;

• 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 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
Data center transition expenses (1)		X		X
Intec acquisition-related charges (1)		X		X
Restructuring charges		X		X
Stock-based compensation		X		X
Amortization of acquired intangible assets		X		X
Amortization of original issue discount (“OID”)		—		X
Gain/loss on repurchase of convertible debt securities		—		X
Unusual income tax matters		—		X

(1) The data center transition project and the Intec acquisition were completed in 2010, and thus, there were no costs for these items in 2011.

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:

• The data center transition expenses 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 operating results with historical and future periods.

• The Intec acquisition-related charges relate to certain direct and incremental expenses related to the acquisition of Intec, and thus, are not considered reflective of CSG’s recurring core business operating results. These charges include expenses related to the following: (i) restructuring; (ii) investment banking, legal, accounting, and other professional services; and (iii) costs primarily related to the settlement of foreign currency hedging instruments associated with the funding of the Intec acquisition. 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.

• 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 operating results with historical and future periods.

• Stock-based compensation results from CSG’s issuance of its common stock to its employees under incentive compensation programs. The amount of this incentive compensation in any period is not

CSG Systems International, Inc.

February 7, 2012

Page 12

generally linked to the level of performance by employees or CSG, but instead is more dependent on CSG’s stock price at the stock grant date, 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. In addition, the stock-based compensation expense is a non-cash expense, 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 subsequent results of operations. In addition, the amortization of acquired intangible assets is a non-cash expense, 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.

• Gains and losses related to the repurchase of CSG’s convertible debt securities are not considered reflective of CSG’s recurring core business operating results. The exclusion of these gains and losses in calculating CSG’s non-GAAP financial measures allows management and investors an additional means to compare CSG’s current operating results with historical and future periods.

• 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, taxes,

CSG Systems International, Inc.

February 7, 2012

Page 13

depreciation, amortization, stock-based compensation, foreign currency transaction adjustments, and unusual items, such as the data center transition expenses, restructuring charges, and Intec acquisition-related 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, 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.

(2) 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.

(3) These items represent the estimated after-tax impact to net income on a per diluted share basis using the following: (i) the estimated income taxes related to these items, which includes the impact of the difference between GAAP and non-GAAP pretax income. This resulted in an overall estimated effective income rate for non-GAAP purposes of approximately 42% and 40%, respectively, for the quarter and year ended December 31, 2011; and (ii) the weighted-average diluted shares outstanding of 32.6 million and 33.0 million, respectively, for the quarter and year ended December 31, 2011.

(4) These items (excluding the one-time adjustments to income tax reserves discussed in Note 5 below) represent the estimated after-tax impact to net income on a per diluted share basis using the following: (i) the estimated income taxes related to these items, which resulted in an overall estimated effective income tax rate for non-GAAP purposes of approximately 31% and 35%, respectively, for the quarter and year ended December 31, 2010; and (ii) the weighted-average diluted shares outstanding of 32.9 million and 33.4 million, respectively, for the quarter and year ended December 31, 2010.

(5) CSG’s GAAP effective income tax rate for the fourth quarter and full year 2010 were approximately 179% and 33%, respectively. These rates differ significantly from CSG’s normal, historical effective income tax rates due to the impact of several unusual income tax matters, which are primarily related to the income tax benefits recorded upon the completion of CSG’s IRS examination during the second quarter of 2010, and the tax treatment of certain Intec acquisition-related charges in the fourth quarter of 2010. This represents the income tax impact of these items.

Free Cash Flow:

CSG’s calculation of non-GAAP free cash flow and the reconciliation of CSG’s non-GAAP free cash flow measure to cash flows from operating activities are provided below for the indicated periods (in thousands):

	Quarter Ended December 31,						Year Ended December 31,
	2011			2010			2011 (8)			2010
Cash flows from operating activities	$	31,825		$	47,074		$	60,959		$	121,309

Non-GAAP free cash flow	$	29,243		$	42,655		$	38,762		$	107,032

(8) The decrease in cash flows from operating activities for the year ended December 31, 2011 relates primarily to: (i) the change in the monthly invoice timing for DISH, which was included as part of its contract renewal terms in January 2011, which had a negative $20 million impact; (ii) an increase in accounts receivable at December 31, 2011, primarily attributed to the normal fluctuations in the timing of client payments made at year-end and to several billing milestones being met towards the end of the fourth quarter of 2011; (iii) the timing of payments for several items specific to the first quarter of 2011, including approximately $8 million of Intec acquisition-related expenses and the 2010 employee incentive bonuses, both of which were accrued at December 31, 2010; and (iv) $6 million payment of deferred income tax liabilities that became due in 2011 as a result of the repurchase of our 2004 Convertible Debt Securities.

Non-GAAP Financial Measures – 2012 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 2012 full year financial guidance, is as follows:

	2012 Guidance
GAAP operating income margin		12	%
Restructuring charges (9)		—
Stock-based compensation (10)		2	%
Amortization of acquired intangible assets (11)		3	%
Non-GAAP operating income margin (“approximately 17%”)		17	%

(9) This represents the pretax impact of restructuring charges of $1 million on CSG’s operating income margin as a percentage of the midpoint of 2012 revenue guidance.

(10) This represents the pretax impact of stock-based compensation expense of an estimated $14 million on CSG’s operating income margin as a percentage of the midpoint of 2012 revenue guidance.

(11) This represents the pretax impact of amortization of acquired intangible assets expense of an estimated $22 million on CSG’s operating income margin as a percentage of the midpoint of 2012 revenue guidance.

Non-GAAP EPS:

The reconciliation of GAAP EPS to non-GAAP EPS as included in CSG’s 2012 full year financial guidance is as follows:

	2012 Guidance Range (12)
	Low Range		High Range
GAAP EPS	$	0.93	$	1.03
Restructuring (13)		0.03		0.03
Stock-based compensation (14)		0.30		0.32
Amortization of acquired intangible assets (15)		0.48		0.51
Amortization of OID (16)		0.11		0.11
Non-GAAP EPS	$	1.85	$	2.00

(12) The estimated after-tax impact of these items is calculated using: (i) the estimated income taxes related to these items, which includes the impact of the difference between GAAP and non-GAAP pretax income, and the anticipated approval of R&D tax credits by the end of 2012, resulting in an estimated effective income rate for non-GAAP purposes of approximately 43%; and (ii) the estimated weighted-average diluted shares outstanding of 32.9 million.

(13) This represents the after-tax impact on a per diluted share basis of the full year restructuring charges of approximately $1 million.

(14) This represents the estimated after-tax impact on a per diluted share basis of the full year stock-based compensation expense of approximately $14 million.

(15) This represents the estimated after-tax impact on a per diluted share basis of the full year amortization of acquired intangible assets expense of approximately $22 million.
