IsoRay Announces Fourth Quarter and Full-Year 2018 Financial Results

Year over year fourth quarter revenues increased 17%
Sixth Consecutive Quarter of Year-Over-Year Revenue Increases
Full year revenues increased 24%

RICHLAND, Wash., September 25, 2018 — IsoRay (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 fiscal fourth quarter and full-year ended June 30, 2018.

Revenue for the fourth quarter ended June 30, 2018 grew 17% to $1.60 million versus $1.37 million in the prior year comparable period. The revenue increase was driven by an increase in both new and existing accounts. Prostate brachytherapy represented 87% of total revenue for the fourth quarter of 2018 compared to 88% in the prior year comparable period. Gross profit as a percentage of revenues declined to 27.3% for the three months ended June 30, 2018 versus 36.4% in the prior year comparable period. The decrease was primarily due to an increase in raw material costs in anticipation of sales growth.

“I am excited to rejoin the company and bring new ideas and develop key opportunities for existing and new products. With the recent growth trajectory of the core business, the expected launches of Blu-Build™ delivery system and GammaTile™ Therapy along with our increasing progress in expanding applications for Cesium-131, we see promise on many fronts. We look forward to building on these important achievements to expand our market presence and fuel continued growth,” IsoRay Interim CEO Lori Woods said.

Total operating expenses in the fourth quarter increased 19% to $2.81 million compared to $2.36 million in the prior year period. Increases in research and development and general and administrative expenses were partially offset by decreases in sales and marketing expenses. General and administrative expenses of $1.56 million included $0.36 million attributable to the executive severance agreement of the former CEO during the quarter. The increase in research and development expense was related to new product development and collaborative research and development expenses related to GT Medical Technologies and the pending launch of GammaTile™ Therapy.

The net loss for the three months ended June 30, 2018 was $2.36 million or ($0.04) per basic and diluted share versus a net loss of $1.85 million or ($0.03) per basic and diluted share in the comparable prior year period.

Revenue for the full year ended June 30, 2018 increased 24% to $5.92 million versus $4.76 million in the prior year comparable period. Prostate brachytherapy represented 86% of total revenue for fiscal 2018 compared to 88% for the fiscal year 2017. Fiscal 2018 sales growth was driven by the revitalized sales and marketing strategy that included significant investments in website design, product support literature and social media and public relations which are increasing the awareness of the Company in the prostate brachytherapy treatment markets. Additionally, IsoRay’s Cesium-131 isotope received increasing interest from clinicians primarily focused on brain and pelvic cancers which resulted in other brachytherapy revenue growing faster than prostate brachytherapy revenue for the full fiscal year ended June 30, 2018. The Company realized a balance of overall revenue growth from both new and existing accounts. Gross profit as a percentage of revenue improved to 31.1% for the year ended June 30, 2018 versus 17.6% in the prior year comparable period. The improvement was driven by leveraging the manufacturing facility, personnel and better utilization of the isotope.

Total operating expenses for the 2018 fiscal year increased 20% to $8.57 million compared to $7.15 million in the prior year period. General and administrative expenses included $0.36 million attributable to the executive severance agreement of the former CEO during the fourth quarter. The increase in research and development expense was primarily related to new product development, specifically Blu-Build™, and collaborative research and development expenses related to GT Medical Technologies and the pending launch of GammaTile™ Therapy. The increase in sales and marketing expenses was related to travel and compensation for new employees and support for revenue growth.

The net loss for the fiscal year ended June 30, 2018 was $6.70 million or ($0.12) per basic and diluted share versus a net loss of $6.16 million or ($0.11) per basic and diluted share in the comparable prior year period.

Cash, cash equivalents, and certificates of deposits at the end of fiscal 2018 totaled $3.43 million versus $8.97 million in the prior year comparable period and the Company had no debt. During the fiscal first quarter of 2019 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.
