Filed by Alliance HealthCare Services, Inc.

Pursuant to Rule 14a-12 under the Securities Exchange Act of 1934

Subject Company: Alliance HealthCare Services, Inc.

Commission File No.: 001-16609

On April 11, 2017, Alliance HealthCare Services, Inc. (“Alliance”) issued the following letter via e-mail to Alliance employees. The press release filed as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on April 11, 2017 was sent as an attachment to the e-mail.

Dear Team Members:

I am pleased to share with you that a merger agreement was signed today with our majority shareholder, Tahoe. This is an important step forward in the process that began in December 2016, and is subject to some remaining conditions. If those conditions are met, it means that Tahoe would acquire all of the outstanding common stock of Alliance that it does not beneficially own currently and the company will become private.

As mentioned previously, on December 12th, our Board of Directors received a letter from Tahoe in which they expressed an interest in acquiring all outstanding shares of Alliance HealthCare Services’ stock that are not currently owned by Tahoe. This merger agreement is the outcome of the work that has been done by the Special Committee of our Board of Directors and its advisors in response to that letter.

There are certain customary closing conditions that must be met in order for the transaction to complete. Most significantly, this merger agreement is subject to approval by holders of a majority of the outstanding shares of Alliance common stock that are not beneficially owned by the members of the Tahoe Group or certain senior executive officers of the Company. To give you a sense of the remaining timing, it is normal for this process to continue for at least the next few months.

What does this mean for our team and for each of you?

It is my strong desire, and also a desire of Tahoe’s, that becoming a private company results in better support our team and strategy, rather than impact us in a negative way. Personally, I am excited for this next step in our evolution. As a private company with an ownership group that is well capitalized and strategically aligned, we become more agile and are better able to capitalize on the opportunities before us. As we have discussed during recent strategy meetings, we are a market leader in the US in our segments and as a result are well positioned to be a leading player as these segments consolidate. While still very early on in our China expansion strategy, it is clear that we have a tremendous opportunity to bring high quality healthcare to this very large market.

It’s important for you and all Team Members to know that Alliance is expected to remain headquartered in southern California. As you know, we have recently signed an 8-year lease for an office space in Irvine for our Resource Center team and our expected move date is May 19th. Alliance’s executive management team is expected to remain in place, and all of Alliance’s divisions within the United States are expected to continue unaffected. I’m very pleased that Tahoe has been and continues to be very supportive of our efforts both in the United States and more recently in China.

If you have any specific questions, please send them to me or to [***] and we will compile a list of FAQs.

Thank you in advance for staying focused on supporting patient care throughout this process. As always, I will continue to update you with information as it becomes available.

Warm Regards,



Tom Tomlinson, CEO
