Third Quarter Operating Results

Segment Commentary

Global Loyalty net revenues increased by $15.4 million, or 35.9%, for the three months ended September 30, 2017 to $58.3 million as compared to $42.9 million for the three months ended September 30, 2016. Global Loyalty net revenues increased for the quarter primarily due to increased growth with existing clients and launches with new clients.

Global Loyalty Segment EBITDA increased by $8.0 million to $22.8 million for the three months ended September 30, 2017 as compared to $14.8 million for the three months ended September 30, 2016. For the quarter, Global Loyalty Segment EBITDA increased as the impact of the higher net revenue was partially offset by higher servicing costs.

Global Customer Engagement net revenues decreased by $1.9 million, or 2.1%, to $90.6 million for the three months ended September 30, 2017 as compared to $92.5 million for the three months ended September 30, 2016. Net revenues decreased primarily as a result of lower net revenues in our engagement solutions business primarily due to the timing of product launches with new clients, as well as lower revenue in our revenue enhancement business.

Global Customer Engagement Segment EBITDA decreased by $0.2 million to $17.0 million for the three months ended September 30, 2017 as compared to $17.2 million for the three months ended September 30, 2016. For the quarter, Global Customer Engagement Segment EBITDA decreased primarily due to lower net revenues, which were partially offset by lower operating expenses.

Insurance Solutions net revenues increased by $0.6 million, or 1.0%, to $59.9 million for the three months ended September 30, 2017 as compared to $59.3 million for the three months ended September 30, 2016. Insurance Solutions net revenues increased for the quarter primarily due to an increase in the average revenue per supplemental insured and a lower cost of insurance principally due to lower claims experience, which were partially offset by the impact of lower supplemental insureds.

Insurance Solutions Segment EBITDA increased by $0.3 million to $22.7 million for the three months ended September 30, 2017 as compared to $22.4 million for the three months ended September 30, 2016. Insurance Solutions Segment EBITDA increased for the quarter primarily due to higher net revenues, partially offset by slightly higher operating expenses.

Legacy Membership and Package net revenues decreased by $9.2 million, or 21.1%, to $34.4 million for the three months ended September 30, 2017 as compared to $43.6 million for the three months ended September 30, 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 with partners, including large financial institutions, as well as a decline in package revenue primarily due to the impact of lower average package members.

Legacy Membership and Package Segment EBITDA increased by $3.6 million to $11.8 million for the three months ended September 30, 2017 as compared to $8.2 million for the three months ended September 30, 2016. Legacy Member and Package Segment EBITDA increased for the quarter as lower net revenues were more than offset by lower general and administrative expenses, lower operating costs and lower marketing and commission expense.

Corporate costs include certain departmental service costs such as human resources, legal, corporate finance and accounting functions, 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.

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 and nine months ended September 30, 2017 and 2016 to Affinion Holdings’ Segment EBITDA, defined as income from operations before depreciation and amortization, and Adjusted EBITDA as defined in note (e) 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 (loss) attributable to Affinion Group Holdings, Inc., see Table 6.
