AMERICAN SHARED HOSPITAL SERVICES
REPORTS FOURTH QUARTER AND 2007 RESULTS

San Francisco, CA, March 3, 2008 — AMERICAN SHARED HOSPITAL SERVICES (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 2007.

Fourth Quarter Results

For the three months ended December 31, 2007, revenue increased to $8,311,000, which included $3,200,000 from the sale of a Leksell Gamma Knife Perfexion^TM system to a clinical partner whose lease agreement on a Gamma Knife expired under its terms in January 2008. This compares to revenue of $4,793,000 for the fourth quarter of 2006.

The 6.6% increase in revenue for the fourth quarter of 2007 versus prior year, net of revenue from the sale of the Perfexion system, primarily reflected the contribution of the IGRT and related equipment and services AMS began supplying another current Gamma Knife customer in September 2007. AMS also completed the upgrade of a clinical partner site from the Gamma Knife to the Perfexion system in October 2007. “Due to its increased therapeutic utility, we believe that per-site revenue from the Perfexion system may ultimately exceed per-site revenue from the previous Gamma Knife models,” said Chairman and Chief Executive Officer Ernest A. Bates, M.D. He added that AMS expects to upgrade two additional sites to the Perfexion system over the next several quarters.

The increase in SG&A expenses for the fourth quarter of 2007 versus prior year primarily reflected higher business development costs. “In view of the expansion of AMS’ growth opportunity, we have increased our investment in marketing and intensified our efforts to win additional contracts from current and new clinical partners,” Dr. Bates said.

Net income for the fourth quarter of 2007 was $178,000, or $0.04 per diluted share, which reflected a 57% effective income tax rate. This compares to net income for the fourth quarter of 2006 of $347,000, or $0.07 per diluted share, which reflected a 50% effective income tax rate. The higher effective income tax rate for the fourth quarter of 2007 reflected adjustments to estimated income taxes for the year primarily due to higher-than- anticipated separate state income taxes at the subsidiary level.

“The new proton beam radiation therapy (PBRT) systems, Leksell Gamma Knife Perfexion systems, IGRT systems, and other next-generation devices for radiation oncology delivery now coming onto the market have the potential to dramatically improve patient outcomes in the treatment of many formerly intractable cancers and other life-threatening conditions. The incremental revenue we anticipated would be triggered by the introduction of the IGRT and Perfexion units has now begun. We expect AMS to be a major participant in this long-term growth opportunity, as we use our creative financing solutions to make the new systems available and affordable to clinical partners who might otherwise find the equipment beyond their reach,” Dr. Bates said.

2007 Results

For the twelve months ended December 31, 2007, revenue increased to $22,622,000 compared to $20,385,000 for 2006.

Net income for 2007 was $951,000, or $0.19 per diluted share, reflecting a 49% effective income tax rate. For 2006, net income was $1,656,000, or $0.33 per diluted share, reflecting a 42% effective income tax rate. The higher effective income tax rate for 2007 is primarily the result of

higher than anticipated state income taxes at the subsidiary level. The Company currently expects its effective income tax rate for 2008 to be approximately 50%. This estimated rate will be reviewed and modified as necessary, at the end of each successive interim period in 2008, to the Company’s best estimate of its annual effective income tax rate.

Balance Sheet Highlights

At December 31, 2007, AMS reported cash, cash equivalents, and short and long-term securities of $10,010,000. At December 31, 2006, AMS reported cash, cash equivalents and short and long-term securities of $8,906,000.
