AMERICAN SHARED HOSPITAL SERVICES

REPORTS FOURTH QUARTER AND 2009 RESULTS

San Francisco, CA, March 23, 2010 AMERICAN SHARED HOSPITAL SERVICES (NYSE AMEX:AMS), a

leading provider of turnkey technology solutions for advanced radiosurgical and radiation therapy

services, today announced financial results for the fourth quarter and 2009.

Fourth Quarter Results

For the three months ended December 31, 2009, revenue decreased to $4,092,000 compared to

$4,740,000 for the fourth quarter of 2008, but increased sequentially from $3,926,000 reported for

the third quarter of 2009. Pre-tax income was $159,000 and the net loss for the fourth quarter of

2009 was $137,000, or ($0.03) per share. This compares to net income of $83,000, or $0.02 per

diluted share, for the fourth quarter of 2008, and to net income of $17,000, or $0.00 per share,

for the third quarter of 2009. Income tax expense was $296,000 primarily due to disproportionately

high income tax expense relating to our profitable operating subsidiary.

The total number of Gamma Knife procedures performed during this year s fourth quarter decreased

1% versus prior year, but increased 5% sequentially. The decrease in revenue also reflected a

shift in volume toward centers with relatively lower payment rates per procedure compared to the

fourth quarter of 2008.

Selling and administrative expenses increased in the quarter versus prior year, primarily to

support the Company s international growth initiatives. This effort culminated in the signing in

February 2010 of the Company s first international radiosurgery contract, a six-year agreement with

the Peruvian Air Force ( FAP ) to supply Gamma Knife services at Hospital Central FAP in Lima,

Cash flow, as measured by earnings before interest, taxes, depreciation and amortization (EBITDA),

was $2,175,000 for the fourth quarter and $8,535,000 for 2009, compared to EBITDA of $2,513,000 for

the fourth quarter of 2008 and $9,811,000 for the year as a whole.

At December 31, 2009, AMS reported cash, cash equivalents and certificates of deposit of

$9,833,000. This compares to cash and cash equivalents of $10,286,000 at December 31, 2008.

Shareholders equity at December 31, 2009 was $22,755,000, or $4.95 per outstanding share. This

compares to shareholders equity at December 31, 2008 of $22,938,000, or $4.87 per outstanding

The Company repurchased 119,000 of its common shares during 2009 for an average purchase price of

$2.28 per share. The number of common shares outstanding at December 31, 2009 was 4,595,070

compared to 4,712,183 at December 31, 2008.

For the twelve months ended December 31, 2009, revenue decreased to $16,768,000 compared to

$19,099,000 for 2008. Pre-tax income was $59,000 and the net loss for 2009 was $188,000, or

($0.04) per share, which included transaction costs of $342,000. This compares to net income for

2008 of $477,000, or $0.10 per diluted share.

As previously disclosed, in 2009 the Company engaged in discussions concerning the possible sale of

its 81% interest in GKF, the operating subsidiary for the Company s Gamma Knife business. These

discussions were terminated on May 28, 2009. Under applicable accounting rules, the Company is

required to expense the legal, accounting, investment banking and other costs incurred for these

activities, which are classified separately as transaction costs.

Discussion and Analysis

Chairman and Chief Executive Officer Ernest A. Bates, M.D. announced today that he was pleased to

announce three exciting new directions for the company.

The first is the resurgence of the Gamma Knife business, a result of the introduction of

the new Perfexion Gamma Knife unit. We are installing two new Perfexion units this year and have

plans to purchase five (5) additional Perfexion systems over the next two years. Treatment

expansion should be aided by recently published articles from the University of Texas M.D. Anderson

Cancer Center and the Karolinska University

Hospital in Sweden that have stated the advantages of the Gamma Knife for treatment of certain

brain tumor patients (180,000 per year) over linear accelerator based whole brain

radiation treatment.

The second new direction is the stretching of our business model across international borders with

the recently announced contract in Peru and two contracts in final negotiation stages in Brazil and

the United Kingdom. The international sales staff has also initiated talks in Mexico and India.

The third exciting new direction involves the company s investment in Still River Systems, Inc.,

the manufacturer of a compact proton beam system that is a cost-effective, disruptive new

technology. Still River has an order backlog of over $200 million. Also, Joe Jachinowski was

recently appointed Chief Executive Officer of Still River Systems. Mr. Jachinowski is one of the

most successful entrepreneurs in America and was previously the co-founder and CEO of IMPAC Medical

Systems. Still River now has three sites under construction at Barnes-Jewish Hospital in St.

Louis, MO, Robert Wood Johnson University Hospital in New Brunswick, NJ and Oklahoma University

Medical Center in Oklahoma City, OK. I am anticipating FDA approval in December of 2011.

Dr. Bates continued, Even as we place additional Gamma Knife, Perfexion and related systems, we

remain focused on building our position in proton beam radiation therapy (PBRT), the next great

growth opportunity in radiation oncology. We recently engaged Siebert Brandford Shank Co. LLC,

one of the nation s leading underwriters of public debt, to act as placement agent in connection

with the debt financing of single and two room PBRT treatment centers that AMS is developing in San

Francisco, New York City, Boston, Orlando and Long Beach, California. We have many additional PBRT

projects in various stages of development, so this is a giant step toward bringing our ambitious

PBRT development program to fruition.
