Record Full Year Revenue

Fiscal Fourth Quarter Revenue Increased 19% Year-Over-Year

RICHLAND, Wash., Sept. 21, 2021 (GLOBE NEWSWIRE) -- Isoray, Inc. (NYSE:ISR), a medical technology company and innovator in seed brachytherapy powering expanding treatment options throughout the body, today announced financial results for the fiscal fourth quarter and full-year ended June 30, 2021.

Revenue for the fourth quarter of fiscal 2021 grew 19% to $2.71 million versus $2.28 million in the prior year comparable period. The Company's core prostate brachytherapy revenue grew 5% when compared to the fiscal fourth quarter of 2020. Prostate brachytherapy represented 74% of total revenue for the fourth quarter of fiscal 2021 compared to 84% in the prior year comparable period. Record non-prostate brachytherapy revenue increased 92% versus the prior year comparable period. The majority of non-prostate brachytherapy revenue in the quarter was comprised of sales to treat brain cancer, including sales of GammaTile^® Therapy.

Gross profit as a percentage of revenues increased to 49.7% for the three months ended June 30, 2021, versus 47.0% in the prior year comparable period. Fourth quarter gross profit increased 26% to $1.35 million versus $1.07 million in the fourth quarter of fiscal 2020, largely attributed to increased sales which were partially offset by higher non-isotope material costs and increased payroll and benefits expense due to greater headcount versus the prior year comparable period.

Isoray CEO Lori Woods said, "Isoray's business is more diversified than it has ever been as represented by a quarter of the fourth quarter revenue being derived from our rapidly growing non-prostate cancer treatments. We continue to believe that the core prostate business is very well-positioned, and we expect to return to the higher pre-pandemic growth rates over time. We also look to continue to selectively diversify our portfolio of targeted radiation therapies and thus our market opportunities and revenue streams going forward."

Woods concluded, "With the talent we have assembled and our focus on growth and new opportunities, we intend to expand Isoray's role as a leader in the broader targeted radiation therapy market."

Total operating expenses increased 8% in the fourth quarter to $2.44 million compared to $2.26 million in the prior year comparable period. Total research and development expenses increased 45% versus the prior year comparable period. The increase in research and development expenses was primarily the result of increased payroll and benefits expense due to greater headcount and higher market research expenses versus the prior year comparable period. Sales and marketing expenses decreased 4% versus the prior year comparable period. The decreases in sales and marketing expenses were driven primarily by decreased incentive compensation which were partially offset by increased travel expenses compared to the prior year comparable period. General and administrative expenses increased 5% versus the prior year comparable period. The increases in general and administrative expenses were primarily the result of increased payroll and benefits expense due to greater headcount and employment hiring expenses which were partially offset by decreased public company related expenses versus prior year comparable period. Historically, the majority of annual employee and director stock grants have been granted in the fiscal fourth quarter, however this year's awards were granted in July 2021, subsequent to the close of the fiscal fourth quarter 2021, thus reducing share-based stock compensation expense in the fourth quarter and full-year fiscal year-end 2021 compared to the prior year quarter and fiscal year.

The net loss for the three months ended June 30, 2021, was $1.06 million or ($0.01) per basic and diluted share versus a net loss of $1.19 million or ($0.02) 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 141.7 million for the three months ending June 30, 2021, versus 68.1 million in the comparable prior year period.

Revenue for the full year ended June 30, 2021 increased 4% to a record $10.05 million versus $9.68 million in the prior fiscal year. Prostate brachytherapy represented 78% of total revenue for fiscal 2021 compared to 86% for the fiscal year 2020. The Company's core prostate brachytherapy product sales declined 6% for the fiscal year 2021 but were more than offset by 68% growth in non-prostate revenue. Full year non-prostate revenue growth was driven by growth in sales to treat brain cancers, including sales of GammaTile Therapy, lung, and head and neck cancers. Gross profit as a percentage of revenue declined to 50.9% for the year ended June 30, 2021 versus 52.9% in the prior fiscal year. The decline in gross margin was the result of increased total cost of product sales due primarily to higher isotope and non-isotope material costs as well as increased payroll and benefits due to an increase in headcount. The company anticipates gross margins in the first and second quarters of fiscal year 2022 to be negatively impacted by approximately 5-10 percentage points as a result of temporary increased costs of goods sold associated with greater isotope purchases related to the initial setup of a second nuclear reactor to support future growth. Gross profit for the full year ended June 30, 2021 was flat at $5.12 million.

Total operating expenses for the 2021 fiscal year decreased to $8.57 million compared to $8.60 million in the prior fiscal year. Total research and development expenses increased 27% versus the prior fiscal year. The year over year increase in total research and development expenses was primarily the result of increases in protocol, payroll, and market research consulting expenses versus the prior fiscal year. Sales and marketing expenses decreased 18% versus the prior year comparable period. The decrease in sales and marketing expenses were primarily driven by decreased incentive compensation and declines in travel and convention costs due to COVID-19 when compared to fiscal year 2020. General and administrative expenses increased 3% versus the prior year comparable period. The increase in general and administrative expenses was driven primarily by increased payroll and benefits expenses due to higher headcount and employment hiring expenses, and insurance premiums which were partially offset by decreases in public company related, legal, and travel expenses when compared to fiscal year 2020.

The net loss for the fiscal year ended June 30, 2021 improved to $3.39 million or ($0.03) per basic and diluted share versus a net loss of $3.47 million or ($0.05) 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 103.8 million for the fiscal year ended June 30, 2021, versus 67.6 million in the prior year comparable year.

Cash, cash equivalents, and certificates of deposit at the end of the fiscal year ended June 30, 2021 totaled $63.8 million and the company had no long-term debt. Stockholders' equity at the end of the fiscal year ended June 30, 2021 totaled $67.4 million.
