Alliance HealthCare Services Investor Presentation January 2017

Disclaimer This presentation includes certain supplemental measures of our performance and liquidity that are not required by, or presented in accordance with, U.S. generally accepted accounting principles (“GAAP“), including Adjusted EBITDA. We present Adjusted EBITDA because we believe that, in addition to GAAP metrics, this non-GAAP metric is a useful measure for investors, for a variety of reasons. Our management regularly communicates Adjusted EBITDA and their interpretation of such results to our board of directors. We also compare actual periodic Adjusted EBITDA against internal targets as a key factor in determining cash incentive compensation for executives and other employees, largely because we view Adjusted EBITDA results as indicative of how our radiology, radiation oncology and interventional healthcare services businesses are performing and are being managed. Adjusted EBITDA is a non-GAAP financial measures and should not be considered as an alternative to net (loss) income attributable to Alliance HealthCare Services, Inc. as a measure of financial performance or cash flows from operations as a measure of liquidity, or any other performance measure derived in accordance with GAAP. The presentation of a non-GAAP metric does not imply that the reconciling items presented are non-recurring, infrequent or unusual. In general, non-GAAP metrics have certain limitations as analytical financial measures and are used in conjunction with GAAP results to evaluate our operating performance and by considering independently the economic effects of the items that are, or are not, reflected in non-GAAP metrics. We compensate for such limitations by providing GAAP-based disclosures concerning the excluded items in our financial disclosures. As a result of these limitations, and because non-GAAP metrics may not be directly comparable to similarly titled measures reported by other companies, however, the non-GAAP metrics are not an alternative to the most directly comparable GAAP measure, or as an alternative to any other GAAP measure of operating performance. Please refer to page 42 of this presentation for reconciliations of Adjusted EBITDA attributable to Alliance HealthCare Services, Inc. The term “LTM ended September 30, 2016” used in this presentation means last twelve months ended September 30, 2016, which data has been calculated by subtracting the data for the nine months ended September 30, 2015 from the data for the year ended December 31, 2015 and adding the data for the nine months ended September 30, 2016.

Disclaimer During the course of this presentation, the Company may make projections or other forward-looking statements regarding, among other things, our business outlook, operations and strategy; service areas; competition; changes in laws and regulations and the impact of such changes on us; our estimates for future performance and operating results, including future revenues, cash flows and capital requirements. In some cases you can identify these statements by words such as “could,” “may,” “expects,” “anticipates,” “believes,” “intends,” “estimates,” or similar words. These forward-looking statements are based largely on the Company’s current expectations and are subject to a number of known or unknown risks and uncertainties (some of which are beyond the Company’s control).

Return to Growth Strategy Launched in 2014, the multi-faceted growth strategy has begun to gain traction. Annual Revenue Quarterly Revenue 5% 10% 13% 13% Q/Q Growth FY14 revenue closed at $436M which was $18M lower than FY13 due to the sale of 24/7 LLC as well as terminations of unprofitable contracts. Since that point in time, we’ve embarked on a return to growth strategy, with continuous revenue growth in 2015 and 2016 despite a strategic price resent that we executed in the radiology market place. FY16 guidance: $505 - $535. $121 $110 $124 $124 $109 $119 $125 6% $473 $436 $449 The term “LTM ended September 30, 2016” as used on this slide means last twelve months ended September 30, 2016, which data has been calculated by subtracting the data for the nine months ended September 30, 2015 from the data for the year ended December 31, 2015 and adding the data for the nine months ended September 30, 2016.
