First Quarter 2017 Financial Results

“Consistent with our expectations for 2017 that we outlined with our guidance for the year, our team delivered solid growth in both revenue and Adjusted EBITDA. Most importantly, Adjusted EBITDA increased by 7.9%, and Adjusted Net Income increased approximately threefold, when compared to the first quarter of 2016. From a balance sheet perspective, we continue to make progress in reducing our long-term debt, which is down $7.7 million compared to December 31, 2016,” stated Tom Tomlinson, Chief Executive Officer and President of Alliance Healthcare Services. “While overall results were solid, we experienced same-store volume challenges in our Oncology business and in the MRI segment of our Radiology business. Fortunately, we have seen strengthening as we moved through the quarter and that improved pace has continued into April. We remain confident that we will deliver results for 2017 that are consistent with the guidance we have provided to investors,” continued Mr. Tomlinson.

Revenue for the first quarter of 2017 increased to $129.9 million, compared to $123.7 million in the first quarter of 2016. This increase was primarily due to increases in Radiology and Oncology revenue of $2.2 million and $4.0 million, respectively.

Adjusted EBITDA for the first quarter of 2017 increased to $32.8 million, compared to $30.4 million in the first quarter of 2016. The increase was primarily due to increases in earnings from Radiology and Oncology, partially offset by Corporate investments as well as a slight decline in the Interventional segment. Adjusted EBITDA growth in both Radiology and Oncology was driven by year-over-year same-store volume growth in PET/CT as well as the addition of new partnerships such as the Northern Alabama Cancer Care Network. The decline in the Interventional business was driven by challenges in physician capacity as well as additional platform investments made to strengthen management and development capabilities. Corporate / Other Adjusted EBITDA decreased due to additional investments in international expansion as well as organization, systems and infrastructure to support expanded workforce, entities and partnerships.

Net loss for the first quarter totaled $0.6 million, compared to net loss of $1.2 million in the first quarter of 2016. The $0.6 million increase in income is largely due to $2.4 million of Adjusted EBITDA generated by our segments, a $1.5 million decrease in share-based compensation expense related to a change in control in connection with Tahoe Investment Group Co., Ltd.’s (“Tahoe’s”) majority ownership purchase of common stock from the Company’s former shareholders on March 29, 2016 (“Tahoe Transaction”), partially offset by an increase of $1.8 million in depreciation and amortization due to our capital investments, a $1.2 million increase in interest expense, net and a $0.9 million decrease in income tax benefit.

GAAP net loss per share on a diluted basis for the first quarter of 2017 was $0.06 per share, compared to GAAP net loss per share of $0.11 in the first quarter of 2016. Excluding the impact of the expenses related to the Tahoe Transaction, GAAP net income per share on a diluted basis would have been $0.09 for the first quarter of 2017, compared to net loss per share of $0.06 in the first quarter of 2016. Adjusted Net Income Per Share was $0.17 and $0.04 for the first quarters of 2017 and 2016, respectively. GAAP net income per share on a diluted basis was impacted by net charges of $0.23 and $0.15 in the first quarters of 2017 and 2016, respectively, which were comprised of: severance and related costs; restructuring charges; transaction costs; shareholder transaction costs; deferred financing costs in connection with shareholder transaction; legal matters expense, net; changes in fair value of contingent consideration related to acquisitions; other non-cash (benefits) charges, net; and differences in the GAAP income tax rate from our historical income tax rate of 42.5%.

Cash flows provided by operating activities totaled $19.9 million for the first quarter 2017, compared to $22.7 million in the first quarter of 2016. Total capital expenditures, including cash paid for equipment purchases and deposits on equipment, totaled $7.3 million for the first quarter 2017 compared to $22.2 million in the first quarter of 2016. Growth capital expenditures totaled $3.9 million and maintenance capital expenditures totaled $3.4 million.

Alliance’s gross debt, defined as total long-term debt (including current maturities but excluding the impact of deferred financing costs), decreased $7.7 million to $565.5 million at March 31, 2017 from $573.2 million at December 31, 2016. Cash and cash equivalents were $21.5 million at March 31, 2017 and $22.2 million at December 31, 2016.

Alliance’s total debt, as defined above, divided by the last twelve months Consolidated Adjusted EBITDA was 4.00x for the twelve month period ended March 31, 2017, compared to 4.03x for the year ended December 31, 2016 and 4.22x for the quarter ended March 31, 2016.

ALLIANCE HEALTHCARE SERVICES, INC.NON-GAAP MEASURES

Total Adjusted EBITDA and Adjusted Net Income Per Share (the “Non-GAAP Measures”) are not measures of financial performance under generally accepted accounting principles in the U.S. (“GAAP”).

Total Adjusted EBITDA, as defined by the Company’s management, is consistent with the definition in the Company’s Credit Agreement and represents net (loss) income before: income tax (benefit) expense; interest expense, net; depreciation expense; amortization expense; share-based payment; severance and related costs; net income attributable to noncontrolling interest; restructuring charges; transaction costs; shareholder transaction costs; impairment charges; legal matters expense (income), net; changes in fair value of contingent consideration related to acquisitions; and other non-cash (benefits) charges, net, which include gain on sale of assets, net. The components used to reconcile net (loss) income to Total Adjusted EBITDA are consistent with our historical presentation of Total Adjusted EBITDA.

Adjusted Net Income Per Share, as defined by the Company’s management, represents net loss before: severance and related costs; restructuring charges; transaction costs; shareholder transaction costs; deferred financing costs in connection with shareholder transaction; legal matters expenses, net; changes in fair value of contingent consideration related to acquisitions; other non-cash (benefits) charges, net; and differences in the GAAP income tax rate compared to our historical income tax rate. The components used to reconcile net loss per share to Adjusted Net Income Per Share are consistent with our historical presentation of Adjusted Net Income Per Share.

Management uses the Non-GAAP Measures, and believes they are useful measures for investors, for a variety of reasons. Management regularly communicates the results of its Non-GAAP Measures and management’s interpretation of such results to its board of directors. Management also compares the Company’s results of its Non-GAAP Measures against internal targets as a key factor in determining cash incentive compensation for executives and other employees, largely because management feels that these measures are indicative of how our radiology, oncology and interventional businesses are performing and are being managed. The diagnostic imaging and radiation oncology industry continues to experience significant consolidation. These activities have led to significant charges to earnings, such as those resulting from acquisition costs, and to significant variations among companies with respect to capital structures and cost of capital (which affect interest expense) and differences in taxation and book depreciation of facilities and equipment (which affect relative depreciation expense), including significant differences in the depreciable lives of similar assets among various companies. In addition, management believes that because of the variety of equity awards used by companies, the varying methodologies for determining non-cash share-based compensation expense among companies and from period to period, and the subjective assumptions involved in that determination, excluding non-cash share-based compensation from Adjusted EBITDA enhances company-to-company comparisons over multiple fiscal periods and enhances the Company’s ability to analyze the performance of its radiology, oncology and interventional businesses.

In the future, the Company expects that it may incur expenses similar to the excluded items discussed above. Accordingly, the exclusion of these and other similar items in the Company’s non-GAAP presentation should not be interpreted as implying that these items are non-recurring, infrequent or unusual. The Non-GAAP Measures have certain limitations as analytical financial measures, which management compensates for by relying on the Company’s GAAP results to evaluate its operating performance and by considering independently the economic effects of the items that are or are not reflected in the Non-GAAP Measures. Management also compensates for these limitations by providing GAAP-based disclosures concerning the excluded items in the Company’s financial disclosures. As a result of these limitations and because the Non-GAAP Measures may not be directly comparable to similarly titled measures reported by other companies, however, the Non-GAAP Measures should not be considered as an alternative to the most directly comparable GAAP measure, or as an alternative to any other GAAP measure of operating performance.

ALLIANCE HEALTHCARE SERVICES, INC.SELECTED STATISTICAL INFORMATIONRADIOLOGY AND ONCOLOGY DIVISION SAME-STORE VOLUME

The Company utilizes same-store volume growth as a historical statistical measure of the MRI and PET/CT imaging procedure, linear accelerator (“Linac”) treatment and stereotactic radiosurgery (“SRS”) case growth at its customers in a specified period on a year-over-year basis. Same-store volume growth is calculated by comparing the cumulative scan, treatment or case volume at all locations in the current year quarter to the same quarter in the prior year. The group of customers whose volume is included in the scan, treatment or case volume totals is only those that received service from Alliance for the full quarter in each of the comparison periods.
