AFFINION GROUP HOLDINGS, INC. ANNOUNCES RESULTS FOR THE FIRST QUARTER

ENDED MARCH 31, 2017

REAFFIRMS FULL YEAR GUIDANCE FOR 2017

STAMFORD, Conn., May 12, 2017 – Affinion Group Holdings, Inc. (“Affinion Holdings” or the “Company”), a global leader in loyalty and customer engagement, announced today the financial results for the three month period ended March 31, 2017 (the “first quarter” or “quarter”) for itself and selected financial information for its wholly-owned subsidiary, Affinion Group, Inc. (“Affinion”).

Key Highlights

“Affinion is off to a strong start in 2017,” said Todd Siegel, the Company’s Chief Executive Officer. “Our core businesses continue to perform well, building on the positive momentum from last year. In particular, we are pleased with the results in our Global Loyalty segment with over 40% revenue growth, driven by our industry leading solutions with existing clients as well as our new client launches during the first quarter.”

“In addition, we recently closed on a transaction that extends our debt maturities to 2022,” continued Siegel. “The transaction provides the Company with sufficient runway to continue to invest in and capitalize on growth opportunities across our core businesses. For the remainder of 2017, we will continue to focus on maintaining and enhancing our broad range of content offerings, service capabilities and technology platforms. Our view remains that the overall business will return to growth in 2017 on a currency consistent basis.”

Notes: The Company does not provide reconciliations of guidance for Adjusted EBITDA to Income from operations, in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K. The Company is unable, without unreasonable efforts, to forecast certain items required to develop meaningful comparable GAAP financial measures. These items include business optimization, restructuring and stock compensation costs, foreign exchange rate changes, as well as other non-cash and unusual items and other adjustments as defined under the Company’s debt agreements, that are difficult to predict in advance in order to include in a GAAP estimate.

Results Highlights

Notes: Adjusted EBITDA as referred to above excludes any pro forma impact of acquisitions and other actions. See Table 5 for a complete description of Adjusted EBITDA by segment and the related reconciliations to GAAP measures. See Tables 6 and 7 for a complete description of Adjusted EBITDA and the related reconciliations to GAAP measures.

First Quarter Net Revenues

First Quarter Operating Results

Segment Commentary

Global Loyalty net revenues increased by $17.1 million, or 42.9%, for the three months ended March 31, 2017 to $57.0 million as compared to $39.9 million for the three months ended March 31, 2016. Global Loyalty net revenues increased for the quarter due to increased growth with existing clients and launches with new clients.

Global Loyalty Segment EBITDA increased by $6.5 million to $20.1 million for the three months ended March 31, 2017 as compared to $13.6 million for the three months ended March 31, 2016. For the quarter, Global Loyalty Segment EBITDA increased as the impact of the higher net revenue was partially offset by higher servicing costs and a charge recorded in relation to the remediation of an external gift card inventory theft. An insurance claim related to the theft is currently being pursued with our carriers and we expect a recovery in a future period which will be recorded when received.

Global Customer Engagement net revenues decreased by $14.4 million, or 13.9%, to $89.2 million for the three months ended March 31, 2017 as compared to $103.6 million for the three months ended March 31,

2016. On a currency consistent basis, net revenues decreased $9.5 million primarily from lower revenue in our revenue enhancement business principally caused by the timing of marketing campaign launches, as well as lower net revenues in our engagement solutions business primarily due to the timing of product launches with new clients. Net revenues declined $4.9 million in the first quarter from the unfavorable impact of foreign exchange.

Global Customer Engagement Segment EBITDA decreased by $6.7 million to $12.9 million for the three months ended March 31, 2017 as compared to $19.6 million for the three months ended March 31, 2016. For the quarter, Global Customer Engagement Segment EBITDA decreased primarily due to lower revenues which were partially offset by lower marketing and commission expense and lower operating and general and administrative expenses. The lower marketing and commission expense was primarily due to the timing of campaign launches and the favorable impact of foreign exchange. The lower operating and general and administrative expenses were primarily related to the favorable impact of foreign exchange.

Insurance Solutions net revenues decreased by $0.7 million, or 1.2%, to $56.7 million for the three months ended March 31, 2017 as compared to $57.4 million for the three months ended March 31, 2016. Insurance Solutions net revenues decreased for the quarter primarily due to lower average supplemental insureds, which were mostly offset by an increase in the average revenue per supplemental insured and a lower cost of insurance principally due to lower claims experience.

Insurance Solutions Segment EBITDA decreased by $1.7 million to $20.0 million for the three months ended March 31, 2017 as compared to $21.7 million for the three months ended March 31, 2016. Insurance Solutions Segment EBITDA decreased for the quarter primarily due to lower revenues and higher operating costs, principally from higher marketing and commission expense.

Legacy Membership and Package net revenues decreased by $16.0 million, or 29.5%, to $38.2 million for the three months ended March 31, 2017 as compared to $54.2 million for the three months ended March 31, 2016. Legacy Membership and Package net revenues decreased for the quarter primarily due to the expected attrition of legacy members and cessation of new marketing campaigns and terminated programs from large financial institution partners, as well as a decline in Package revenue primarily due to the impact of lower average Package members.

Legacy Membership and Package Segment EBITDA decreased by $1.1 million to $9.0 million for the three months ended March 31, 2017 as compared to $10.1 million for the three months ended March 31, 2016. Legacy Member and Package Segment EBITDA decreased for the quarter primarily due to the lower net revenues which were partially offset by lower marketing and commission expense, lower operating costs and lower general and administrative expenses.

Corporate costs include certain departmental service costs such as human resources, legal, corporate finance and accounting, and unallocated portions of information technology. Expenses, such as professional fees related to debt financing activities and stock compensation costs, are also recorded in corporate. Corporate costs decreased by $4.5 million to $12.6 million for the three months ended March 31, 2017 as compared to $17.1 million for the three months ended March 31, 2016. Corporate costs decreased for the quarter primarily the result of lower legal costs and cost savings initiatives.

UNAUDITED OPERATING SEGMENT RESULTS

(In millions)

Net revenues, Segment EBITDA and Adjusted EBITDA by operating segment are as follows, including a reconciliation of Affinion Holdings’ income from operations for the three months ended March 31, 2017 and 2016 to Affinion Holdings’ Segment EBITDA, defined as income from operations before depreciation and amortization, and Adjusted EBITDA as defined in note (f) of Table 6:

TABLE 5 –cont’d

We believe that Adjusted EBITDA for each segment provides supplemental information useful to investors as it is frequently used by the financial community to analyze performance period to period, to analyze a company’s ability to service its debt and to facilitate comparisons among companies. We believe Adjusted EBITDA also provides additional supplemental information to compare results among our segments. However, Adjusted EBITDA by segment is not a measurement of financial performance under U.S. GAAP, and Adjusted EBITDA by segment may not be comparable to similarly titled measures of other companies. You should not consider Adjusted EBITDA by segment as an alternative to operating or net income determined in accordance with U.S. GAAP, as an indicator of operating performance or as an alternative to cash flows from operating activities, determined in accordance with U.S. GAAP, or as an indicator of cash flows, or as a measure of liquidity. For a discussion of the definition of Adjusted EBITDA and the reconciliation of Adjusted EBITDA to consolidated net income attributable to Affinion Group Holdings, Inc., see Table 6.
