Caution Regarding Forward-Looking Information
In addition to historical information, this Form 10-Q contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (PSLRA). This statement is included for the express purpose of availing Isoray, Inc. of the protections of the safe harbor provisions of the PSLRA.
All statements contained in this Form 10-Q, other than statements of historical facts, that address future activities, events or developments are forward-looking statements, including, but not limited to, statements containing the words “believe,” “expect,” “anticipate,” “intends,” “estimate,” “forecast,” “project,” and similar expressions. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including any statements of the plans, strategies and objectives of management for future operations; any statements concerning proposed new products, services, developments or industry rankings; any statements regarding future revenue, economic conditions or performance; any statements of belief; and any statements of assumptions underlying any of the foregoing. These statements are based on certain assumptions and analyses made by us in light of our experience and our assessment of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. However, whether actual results will conform to the expectations and predictions of management is subject to a number of risks and uncertainties described under Item 1A - Risk Factors beginning on below that may cause actual results to differ materially.
Consequently, all of the forward-looking statements made in this Form 10-Q are qualified by these cautionary statements and there can be no assurance that the actual results anticipated by management will be realized or, even if substantially realized, that they will have the expected consequences to or effects on our business operations. Readers are cautioned not to place undue reliance on such forward-looking statements as they speak only of the Company’s views as of the date the statement was made. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
Critical Accounting Policies and Estimates
The discussion and analysis of the Company’s financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an on-going basis, management evaluates past judgments and estimates, including those related to bad debts, inventories, accrued liabilities, derivative liabilities and contingencies. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The accounting policies and related risks described in the Company’s annual report on Form 10-K as filed with the SEC on September 27, 2019 are those that depend most heavily on these judgments and estimates. As of September 30, 2019 there had been no material changes to any of the critical accounting policies contained therein.
Overview
Isoray is a brachytherapy device manufacturer with FDA clearance for a single medical device that can be delivered to the physician in multiple configurations as prescribed for the treatment of cancers in multiple body sites. The Company manufactures and sells this product as the Cesium-131 brachytherapy seed.
The brachytherapy seed utilizes Cesium-131, with a 9.7 day half-life, as its radiation source. The Company believes that it is the unique combination of the short half-life and the energy of the Cesium-131 isotope that are yielding the beneficial treatment results that have been published in peer reviewed journal articles and presented in various forms at conferences and tradeshows.
The Company has distribution agreements outside of the United States. These distributors are responsible for obtaining regulatory clearance to sell the Company’s products in their territories, with the support of the Company. As of the date of this Report, the Company has distributors in the Russian Federation and Peru with no reported revenues in these locations during the three months ended September 30, 2019.
The Company has a supply agreement with The Open Joint Stock Company <<Isotope>>, a Russian company, for the supply of Cesium-131, which was recently extended by an addendum through December 31, 2019 and the volume was also modified. Under the addendum, current pricing and volumes for Cesium-131 purchases remained in place until May 31, 2019. On July 11, 2019, another addendum was signed extending the pricing terms until August 4, 2019. On July 30, 2019, a new supply contract was signed with The Open Joint Stock Company for a term of August 2019 to December 2020 as the Company had purchased the maximum amount of Cesium-131 permitted under the prior agreement. The Company also has a consignment inventory agreement with MedikorPharma-Ural LLC (“Medikor”) to process the Company’s enriched barium at another nuclear reactor in Russia. The term of this consignment agreement began in November 2017 and is for 10 years. Our source of supply of Cesium-131 from Russia is historically produced using one of two nuclear reactors which supply the irradiation needed for Cesium-131 production. One of the Russian nuclear reactors was shut down from December 2017 until August 2018, and the other Russian nuclear reactor shut down in August 2019 and is scheduled to be shut down into 2020. As a result of these scheduled shutdowns, only one of the Company's historic Russian suppliers of Cesium-131 will be available during these periods.

Prostate Brachytherapy
Prostate sales growth of approximately 51% during the three months ended September 30, 2019 compared to the three months ended September 30, 2018 was achieved due to a sustained focus on acquiring new accounts through physician training programs and marketing campaigns along with continued support of existing customers to help them grow their business. While in a limited market release, the Blu Build™ loader also contributed to prostate revenue growth as it was sold to new customers that desired the intraoperative loader system. The Company continues to update its website and other marketing collateral as well as attending tradeshows to acquire new leads for our sales personnel. Also, the website along with some social media campaigns have been used to educate patients about the availability of Cesium-131 as a treatment option.
Management believes continued growth in prostate brachytherapy revenues will be the result of physicians, payors, and patients increasingly considering overall treatment advantages including costs compared with non-brachytherapy treatments, better treatment outcomes and improvement in the quality of life for patients. We believe the trend to use brachytherapy in lieu of other options is starting to improve our performance but there is no assurance as to how long this trend will continue.
Management believes increased pressure to deliver effective healthcare in both terms of outcome and cost drove treatment options, and accordingly drove the Company’s prostate revenues, during the three months ended September 30, 2019.
Other Sales
Other sales includes, but is not limited to, brain, lung, head/neck, gynecological treatments, and services. Other sales, net increased by 30% for the three months ended September 30, 2019 compared to the three months ended September 30, 2018. Initial applications for these other brachytherapy treatments are primarily used in recurrent cancer treatments or salvage cases that are generally difficult to treat aggressive cancers where other treatment options are either ineffective or unavailable.
Other brachytherapy treatments are subject to the influence of a small pool of innovative physicians who are the early adopters of the technology who also tend to be faculty at teaching hospitals training the next generation of physicians. This causes the revenue created by these types of treatment applications to be more volatile and varies significantly from year to year. Additionally, with other brachytherapy surgical procedures there remains inconsistency and uncertainty regarding reimbursement for the procedures. This unreliable reimbursement for these new procedures will remain until specific coding and coverage policies are established, which could take years. Individual centers weigh the value of the procedure with their other treatment priorities on a patient by patient basis. Isoray believes that additional clinical data will begin to build a compelling argument to support reimbursement and increased adoption of the procedures; however, any growth will be inconsistent in the near term.
GammaTile™
For several years the Company has focused on many different applications of its Cesium-131 brachytherapy seeds in the cranial cavity to target many forms of brain cancer. Most recently, the Company has focused on using braided strand configurations and on being a contract manufacturer of GammaTile™ Therapy which is owned by GT Medical Technologies, Inc. (GT Med Tech). GammaTile™ Therapy uses biodegradable “tiles” to deliver Cesium-131 brachytherapy seeds into contact with cancerous tumors in the brain.
Currently, GammaTile™ Therapy is cleared for treating recurrent brain cancers. Recently, GT Med Tech filed a 510k with the FDA on an expanded indication of GammaTile™ Therapy to include newly diagnosed brain tumors. If cleared this could lead to a growing opportunity for the expanded application of Cesium-131. As of September 30, 2019, we understand that GT Med Tech has an expanded indication under active review by the FDA. For the three months ended September 30, 2019, total revenues from sales to GT Med Tech were nominal. There were no sales to GT Med Tech for the three months ended September 30, 2018 as GT Med Tech began the limited market release of GammaTile™ Therapy in January 2019. While GT Med Tech continues to assure Isoray that its sales and marketing efforts will show steady improvements in sales there is no assurance this will occur.
Cost of sales consists primarily of the costs of manufacturing and distributing the Company’s products.
Contributing to the quarters ended September 30, 2019 and 2018 comparison were increased other direct materials purchases as well as increased labor to meet production demand due to improved sales. Although sales improved dramatically, the increase in cost of sales was only nominal primarily as a result of cost savings in isotope due to the termination of use of our domestic isotope supplier that occurred in fiscal year 2019 which resulted in lower isotope unit costs compared to the quarter ended September 30, 2018 and more efficient isotope usage driven by the increased revenue that led to lower losses of isotope due to decay.
Gross Profit
Contributing to the three months ended September 30, 2019 and 2018 gross profit comparison were increased sales and significantly lower isotope unit costs compared to the prior year comparable period, continued leverage of the fixed cost components within costs of sales, and more efficient isotope usage. The lower isotope unit costs are related to the previously discussed change in our supply chain made at the end of calendar year 2018.
Research and development
Total research and development expense decreased 45% as compared to the quarter ended September 30, 2018.
Proprietary research and development consists primarily of employee and third party costs related to research and development activities.
Contributing to the quarters ended September 30, 2019 and 2018 proprietary research and development comparison were a decrease in protocol expense primarily relating to a mutually-agreed termination of a grant agreement which resulted in a reversal of the accrual and a reduction in investment in the development of the Blu Build™ delivery system for real-time prostate brachytherapy.
Collaboration arrangement related costs are incurred, shared, and separately stated in connection with a collaborative research and development project.
Contributing to the quarters ended September 30, 2019 and 2018 comparison were decreased costs due to the fact that payments being made pursuant to the collaborative arrangement with GammaTile, LLC were no longer necessary, as the collaborative arrangement primarily related to work involved in obtaining 510(k) clearance, which has now been obtained.
Management believes that research and development expenses will return to near historic norms as we do not anticipate accrual reversals in the future and other increases are likely for new projects and collaborations planned in the future.
Sales and marketing expenses consist primarily of the costs related to the internal and external activities of the Company’s sales, marketing and customer service functions of the Company. As the Company increasingly focuses on improving sales, the cost associated with marketing and additional staffing continues to increase.
Contributing to the quarters ended September 30, 2019 and 2018 comparison was an increase in travel costs as a tradeshow that occurred in October 2018 occurred in September 2019. Incentive compensation increased for the quarter ended September 30, 2019 in connection with the increase in revenue.
General and administrative expenses consist primarily of the costs related to the executive, human resources/training, quality assurance/regulatory affairs, finance, and information technology functions of the Company.
Contributing to the quarters ended September 30, 2019 and 2018 comparison were various cost increases. Those include increase in headcount, salary increases implemented in July 2019, and incentive compensation related to the increase in revenue.
Liquidity and capital resources
The Company assesses its liquidity in terms of its ability to generate cash to fund its operating, investing and financing activities. The Company has historically financed its operations through selling equity to investors. During the quarters ended September 30, 2019 and 2018, the Company used existing cash reserves to fund its operations and capital expenditures (in thousands except current ratio):

Cash flows from operating activities
Net cash used by operating activities in the three months ended September 30, 2019 was primarily due to a net loss of approximately $809,000, net of approximately $37,000 in adjustments for non-cash activity such as depreciation and amortization expense, share-based compensation, and change in estimate of asset retirement obligation. Changes in operating assets and liabilities provided approximately $90,000 from operating activities; decreases to prepaid expenses and increases to accounts payable and accrued expenses and accrued payroll and related taxes were partially offset by increases in accounts receivable resulting from higher sales as well as a decrease in accrued protocol expense primarily relating to a mutually-agreed termination of a grant agreement.
Net cash used by operating activities in the three months ended September 30, 2018 was primarily due to a net loss of approximately $1.51 million, net of approximately $140,000 in adjustments for non-cash activity such as depreciation and amortization expense, and share-based compensation. Changes in operating assets and liabilities used approximately $249,000 to fund operating activities; increases to prepaid expenses and decreases to accounts payable and accrued expenses and accrued payroll and related taxes were partially offset by decreases in accounts receivable resulting from improved collections as well as an increase in accrued protocol expense.
Cash flows from investing activities
Investing activities for the three months ended September 30, 2019 consisted of transactions related to the purchase of fixed assets, including automation of production processes. Management will continue to invest in technology and machinery that improves and streamlines production processes and to invest in low-risk investment opportunities that safeguard assets and provide greater assurance those resources will be liquid and available for business needs as they arise.
Investing activities for the three months ended September 30, 2018 consisted of transactions related to the purchase of fixed assets, including automation of production processes, as well as the purchase and subsequent maturity of certificates of deposit.
Cash flows from Financing activities
There were no financing activities in the quarter ended September 30, 2019.
Financing activities in the quarter ended September 30, 2018 were due to the sale of common stock through a registered direct offering.
Projected fiscal 2020 liquidity and capital resources
Operating activities
Assuming no extraordinary expenses occur (whether operating or capital), if management is successful at implementing its strategy of renewed emphasis on driving the consumer to the prostate market, meets or exceeds its annual growth targets of twenty-five percent increase in revenue in fiscal 2020 and this annual growth continues, the Company anticipates reaching cash flow break-even in. The Company exceeded that target of twenty-five percent increased revenue in the first quarter of fiscal 2020. There is no assurance that targeted sales growth will continue over the next three to four years..
Capital expenditures
Management has completed the design of a future production and administration facility. If financing is obtained and the facility constructed, it is believed that the new facility will have non-cash depreciation cost equal to or greater than the monthly rental cost of the current facility.
Management is reviewing all aspects of production operations (including process automation), research and development, sales and marketing, and general and administrative functions to evaluate the most efficient deployment of capital to ensure that the appropriate materials, systems, and personnel are available to support and drive sales.
During the three months ended September 30, 2019, the Company invested approximately $72,000 in the automation of production processes. Beginning in fiscal 2017 and continuing through September 30, 2019, the Company has invested approximately $912,000 in the automation of five production processes, four of which have been placed in service as of the end of September 30, 2019. but there is no assurance that this amount will not be revised. This investment is designed to allow the Company to significantly increase the output of Cesium-131 brachytherapy seeds, while allowing the Company to decrease the labor costs related to seed production and also improving the overall safety of our operations.

Critical accounting policies and estimates
The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as revenue and expenses during the reporting periods. The Company evaluates its estimates and judgments on an ongoing basis. The Company bases its estimates on historical experience and on various other factors the Company believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Actual results could therefore differ materially from those estimates if actual conditions differ from our assumptions.
During the quarter ended September 30, 2019, there have been no changes to the critical accounting policies and estimates discussed in Part II, Item 7 of our Form 10-K for the year ended June 30, 2019.
ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There have been no material changes to the disclosure in the “Quantitative and Qualitative Disclosures about Market Risk Factors” section of our annual report on Form 10-K for the year ended June 30, 2019.
ITEM 4 – CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our principal executive officer and co-principal financial officers, we conducted an evaluation of the design and operation of our disclosure controls and procedures, as such term is defined under Rules 13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of September 30, 2019. Based on that evaluation, our principal executive officer and our co-principal financial officers concluded that the design and operation of our disclosure controls and procedures were effective. The design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. However, management believes that our system of disclosure controls and procedures are designed to provide a reasonable level of assurance that the objectives of the system will be met.
Changes in Internal Control over Financial Reporting
There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
