Year Over Year First Quarter Revenues Increased 29%
Double Digit Revenue Increases Year Over Year for Sixth Consecutive Quarter

RICHLAND, Wash., Nov. 08, 2018 (GLOBE NEWSWIRE) — IsoRay, Inc. (NYSE AMERICAN: ISR), a medical technology company and innovator in seed brachytherapy powering expanding treatment options throughout the body, today announced its financial results for the first quarter fiscal 2019 ended September 30, 2018.

Revenue for the first quarter fiscal 2019 grew 29% to $1.56 million versus $1.21 million in the prior year comparable period. The revenue increase was driven by continued sales execution in the company’s core prostate brachytherapy markets as well as in brachytherapy sales for treatment of other cancers. Prostate brachytherapy represented 88% of total revenue for the first quarter of 2019 compared to 89% in the prior year comparable period. Additionally, year over year growth in non-prostate brachytherapy revenue was driven by growth in sales to treat brain, lung, and head and neck cancers.

Gross profit as a percentage of revenues increased to 33.5% for the three months ended September 30, 2018 versus 21.9% in the prior year comparable period. First quarter gross profit increased 98% to $0.52 million versus $0.27 million in the first quarter of fiscal 2018, largely attributed to increased sales and the company’s continued improvement in utilization of the isotope.

IsoRay Interim CEO Lori Woods said, “We are pleased with the continued growth in revenues and the demonstrated strong sales momentum that has continued into fiscal 2019. We intend to build on this momentum with the incremental growth of revenues from our new product, Blu-Build™, and from our role as the manufacturer of GammaTile™ Therapy for GT Medical Technologies, Inc.”

Woods concluded, “We have reached an important milestone with the successful completion of the first case involving the treatment of prostate cancer utilizing our customizable, intra-operative Cesium-131 Blu-Build delivery system. The case was completed on October 26 at the Medical University of South Carolina. We are confident that we have the right products at the right time that will allow us to execute our plans for future growth.”

Total operating expenses in the first quarter were $2.04 million compared to $1.82 million in the prior year period. Total research and development expenses increased 16% versus the prior year comparable period. The increase in total research and development expenses was primarily the result of increases in proprietary new product development expenses related to the Blu-Build delivery system, which was partially offset by the year-over-year decline in collaborative research and development expenses related to GT Medical Technologies and their pending launch of GammaTile Therapy. Sales and marketing expenses increased 6% versus the prior year comparable period. General and administrative expenses increased 16% versus the prior year comparable period, primarily the result of an increase in headcount and incentive compensation related to the increase in revenue.

The net loss for the three months ended September 30, 2018 was $1.51 million or ($0.02) per basic and diluted share versus a net loss of $1.55 million or ($0.03) per basic and diluted share in the comparable prior year period. Basic and diluted per share results are based on weighted average shares outstanding of approximately 66.1 million for the three months ended September 30, 2018 versus 55.0 million in the comparable prior year period.

During the quarter, the company closed a public offering of 11.0 million shares of its common stock at a price of $0.75 per share. Gross proceeds, before underwriting discounts, commissions and estimated offering costs, were approximately $8.25 million. Cash, cash equivalents, and short-term investments at the end of the first quarter of fiscal 2019 totaled $9.19 million and the company had no debt.
