Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations (continued)





Executive Summary


In March 2020, the World Health Organization declared the coronavirus disease (COVID-19) a global pandemic and recommended containment and mitigation measures worldwide. We continue to comply with executive orders issued in Ohio and U.S. Centers for Disease Control and Prevention guidelines regarding safety procedures directly related to the pandemic. These procedures include, but are not limited to: wearing masks, social distancing, staggering start times, remote working, and teleconferencing versus in person meetings. We are encouraging all employees to obtain a vaccine when available and eligible. We continue to maintain regular contact, via phone and other electronic means, with our customers and suppliers.

Based on recent conversations with customers, we do not expect to experience any material impairments and do not anticipate any changes in accounting judgements related to COVID-19. We are not aware of any material adverse impact on our supply chain and remain in contact with our suppliers. Although we continue to face a period of uncertainty regarding the ongoing impact of the COVID-19 pandemic and emergence of new variants on our projected customer demand, market conditions continue to gradually improve. In the midst of this challenging environment, we remain focused on taking the necessary steps to respond quickly to changes in our business through specific contingency plans including (but not limited to): reviewing and monitoring planned capital expenditures, reviewing all operating expenses for opportunities to reduce spending, and aligning inventory to estimated revenue.

We continue to monitor the evolving situation related to COVID-19 including guidance from federal, state, and local public health authorities and may take additional actions based on these recommendations. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan. As such, given the dynamic nature of this situation, we cannot reasonably estimate the impacts of COVID-19 or the emergence of new variants on our results of operations, cash flows and liquidity in the future.

There have recently been public reports and announcements of a global semiconductor chip shortage that is anticipated to continue into at least the second half of 2021. It is impacting companies across a wide range of industries, including some of our customers, which could temporarily impact the Company's revenue and volume. We continue to actively monitor these developments, including ongoing contact with our suppliers and customers, and adapting to their specific circumstances and forecasts.

On April 17, 2020 we entered into an unsecured promissory note under the Paycheck Protection Program (the "PPP"), with a principal amount of $325,300. The PPP was established under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and is administered by the U.S. Small Business Administration (the "SBA"). The SBA approved our Forgiveness Application in full on January 6, 2021.

The Employee Retention Credit, as originally enacted on March 27, 2020 by the CARES Act, is a refundable tax credit against certain employment taxes equal to 50% of the qualified wages an eligible employer pays to employees after March 12, 2020, and before January 1, 2021. The Taxpayer Certainty and Disaster Tax Relief Act (the "Relief Act"), enacted on December 27, 2020, amended, and extended the Employee Retention Credit. On March 1, 2021, the IRS released Notice 2021-20 to provide guidance on the original Employee Retention Credit, as modified by the Relief Act. During the first quarter of 2021 we filed Form 941-X to claim a credit of $105,000 on qualified wages paid in 2020. This receivable appears on the balance sheet as of March 31, 2021 as Tax Receivable and as a credit to wages in the Statement of Operations during the three months ended March 31, 2021.

The Relief Act extended and enhanced the Employee Retention Credit for qualified wages paid after December 31, 2020 through June 30, 2021. Under the Relief Act, eligible employers may claim a refundable tax credit against certain employment taxes equal to 70% of the qualified wages an eligible employer pays to employees after December 31, 2020 through June 30, 2021.

During the first quarter of 2021, we experienced a decline in gross receipts of 25% compared to the first quarter of 2019 which qualified us to receive this credit. We filed Form 941 for the first quarter of 2021 and claimed a credit of $150,507 on qualified wages paid in the first quarter of 2021. This receivable appears on the Balance Sheet as of March 31, 2021 as Tax Receivable and as a credit to wages in the Statement of Operations during the three months ended March 31, 2021. As previously mentioned, an employer that has a decline continues to be eligible until the end of the calendar quarter in which gross receipts are greater than 80% of its 2019 calendar quarter receipts. Thus, we expect to be eligible for this credit for a similar amount at least through the second quarter of 2021.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations (continued)

For the three months ended March 31, 2021, we had total revenue of $3,022,310. This was a decrease of $416,485, or 12.1%, compared to the three months ended March 31, 2020. The decrease was principally due to lower pricing in the first quarter of 2021, which was partially offset by higher volume and product mix.

Gross profit was $803,036 for the three months ended March 31, 2021 compared to $509,338 for the same three months in 2020. This increase was due to volume, product mix, improved manufacturing efficiency, and approximately $151,000 related to the Employee Retention Credit.

Operating expenses were $377,493 and $421,853 for the three months ended March 31, 2021 and 2020, respectively.

Income from operations was $425,543 and $87,485 for the three months ended March 31, 2021 and 2020, respectively which included $255,507 related to the Employee Retention Credit.

Consistent with our growth strategy, we have identified niche markets that can benefit from our expertise in custom powder solutions, such as near infrared doped phosphors and short-wave infrared applications. These applications enable extended life of phosphors for specific nighttime identification needs of defense personnel and first responders.

New initiatives are also being pursued that utilize our vacuum hot press, cold isostatic press, and kilns for development projects, including diffusion bonding. We recently manufactured and sold conductive metal oxides for direct current sputtering of Tungsten Oxide and Molybdenum Oxide materials. We continue to invest in developing new products for all our markets including transparent conductive oxide systems for the solar and display markets as well as with our transparent electronic products. Those products involve research and development expense to accelerate time to market.





RESULTS OF OPERATIONS


Three months ended March 31, 2021 (unaudited) compared to three months ended March 31, 2020 (unaudited):





Revenue


For the three months ended March 31, 2021, we had total revenue of $3,022,310. This was a decrease of $416,485, or 12.1%, compared to the three months ended March 31, 2020. The decrease was principally due to lower pricing in the first quarter of 2021, which was partially offset by higher volume and product mix.





Gross profit


Gross profit was $803,036 for the three months ended March 31, 2021 compared to $509,338 for the same three months in 2020. This was an increase of $293,698, or 57.7%. Gross profit as a percentage of revenue (gross margin) was 26.6% for the first quarter of 2021 compared to 14.8% for the same period in 2020. This increase was due to volume, product mix, improved manufacturing efficiency and the Employee Retention Credit of approximately $151,000.

General and administrative expense

General and administrative expense for the three months ended March 31, 2021 and 2020, was $287,881 and $283,165, respectively, an increase of 1.7%. Increases in compensation and professional fees were offset by the Employee Retention Credit of $36,000.





                                       17




Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations (continued)

Included in general and administrative expense was $62,425 and $63,582 for professional fees for the three months ended March 31, 2021 and 2020, respectively. These expenses were primarily related to SEC compliance costs for legal, accounting and stockholder relations fees.

Research and development expense

Research and development expense for the three months ended March 31, 2021, was $38,219 compared to $86,904 for the same period in 2020, a decrease of 56.0%. This decrease is primarily related to the Employee Retention Credit of $39,000. Specialty materials are being researched for use in niche markets which include custom applications and additive manufacturing. Our development efforts utilize a disciplined innovation approach focused on accelerating time to market for these applications and involve ongoing research and development expense.





Marketing and sales expense



Marketing and sales expense was $51,393 and $51,784 for the three months ended March 31, 2021 and 2020, respectively. Higher outside consulting expenses and compensation related to an increase in staff were offset by the Employee Retention Credit of approximately $30,000.





Stock compensation expense


Included in total expenses were non-cash stock-based compensation costs of $21,888 and $31,180 for the three months ended March 31, 2021 and 2020, respectively. Compensation expense for all stock-based awards is based on the grant date fair value and recognized over the required service (vesting) period. Unrecognized non-cash stock-based compensation expense was $9,851 as of March 31, 2021 and will be recognized through 2023.





Interest


Interest expense was $7,638 and $4,069 for the three months ended March 31, 2021 and March 31, 2020, respectively. Lower interest income during the first quarter of 2021 resulted in an increase to overall interest expense.





Income taxes


Income tax expense was $90,620 and $1,900 for the three months ended March 31, 2021 and 2020, respectively. In December 2020, we reversed in full our valuation allowance that had been recorded against the unrealizability of the deferred tax asset, which resulted in the recording of the asset of $1,019,317 at December 31, 2020. Management considered new evidence, both positive and negative, during the first quarter of 2021 that could affect its view of the future realization of deferred tax assets and determined that no valuation allowance was necessary at March 31, 2021, and the deferred tax asset was $931,475 at March 31, 2021.

Income Applicable to Common Stock

Income applicable to common stock for the three months ended March 31, 2021 and 2020, was $646,547 and $75,478, respectively. The increase was primarily the result of higher gross profit, as well as the forgiveness of the PPP Loan, and the Employee Retention Credit.

Liquidity and Capital Resources





Cash


As of March 31, 2021, cash on hand was $3,006,933 compared to $2,917,551 at December 31, 2020.

Cash increased $89,382, receivables increased $278,476 and short term notes payable (PPP Loan) decreased $252,577 during the first quarter of 2021. Accounts payable increased $151,304.





Cash from Operations


Net cash provided by operating activities was $452,394 and $170,612 during the three months ended March 31, 2021 and 2020 respectively. This included depreciation and amortization of $135,313 and $132,408, and non-cash stock-based compensation costs of $21,888 and $31,180 for the three months ended March 31, 2021 and 2020, respectively. Due to orders received during the first quarter of 2021 inventories increased $2,250,524 and accrued expenses and customer deposits increased $2,230,664. In addition, the extinguishment of debt of $325,000 related to the PPP loan occurred during the first quarter of 2021.

Cash from Investing Activities

During the three months ended March 31, 2021, $319,578 was used in investing activities for the purchase of production equipment. Cash of $157,237 was used in investing activities during the three months ended March 31, 2020, for the acquisition of production equipment.

Cash from Financing Activities

Cash of $43,454 and $24,152 was used in financing activities for principal payments to third parties for finance lease obligations during the three months ended March 31, 2021 and 2020, respectively. The increase is due to the commencement of a finance lease during the third quarter of 2020 for the rebuild of production equipment.





Debt outstanding


Total debt outstanding decreased to $360,179 at March 31, 2021, from $728,934 at December 31, 2020, a decrease of 50.6%. As previously mentioned, cash of $43,454 was used for principal payments for finance lease obligations and our PPP loan of $325,300 was forgiven in full by the SBA.

Off Balance Sheet Arrangements

We have no off-balance sheet arrangements including special purpose entities.





Critical Accounting Policies


The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported in the Financial Statements and accompanying notes. Note 2 to the Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2020, describes the significant accounting policies and methods used in the preparation of the Financial Statements. Estimates are used for, but not limited to, accounting for the allowance for doubtful accounts, inventory allowances, property and equipment depreciable lives, patents and licenses useful lives, revenue recognition, income tax expense, deferred tax assets and liabilities, realization of deferred tax assets, stock-based compensation and assessing changes in which impairment of certain long-lived assets may occur. Actual results could differ from these estimates. The following critical accounting policies are impacted significantly by judgments, assumptions and estimates used in the preparation of the Financial Statements. The allowance for doubtful accounts is based on our assessment of the collectability of specific customer accounts and the aging of the accounts receivable. If there is a deterioration of a major customer's credit worthiness or actual defaults are higher than our historical experience, our estimates of the recoverability of amounts due us could be adversely affected. Inventory purchases and commitments are based upon future demand forecasts. If there is a sudden and significant decrease in demand for our products or there is a higher risk of inventory obsolescence because of rapidly changing technology and customer requirements, we may be required to increase our inventory allowances and our gross margin could be adversely affected. The tax valuation allowance is based on our consideration of new evidence, both positive and negative, that could affect our view of the future realization of deferred tax assets. If we were to determine we would not be able to realize all or part of the deferred tax asset in the future, an adjustment to the deferred tax asset would be necessary which would reduce our net income for that period. Depreciable and useful lives estimated for property and equipment, licenses and patents are based on initial expectations of the period of time these assets and intangibles will benefit us. Changes in circumstances related to a change in our business, change in technology or other factors could result in these assets becoming impaired, which could adversely affect the value of these assets.
