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. Since then, most federal, state, and local executive orders have been lifted and we continue to follow practical safety procedures. These procedures include, but are not limited to: wearing masks, social distancing, staggering start times, and teleconferencing versus in person meetings. Almost all of our employees have been fully vaccinated. We recently resumed in person meetings with some customers and continue to maintain regular contact, via phone and other electronic means, with other customers and suppliers.

Based on recent conversations with customers, we do not expect to experience any material impairments or changes in accounting judgements related to COVID-19. We are not experiencing any material adverse impact in our supply chain and remain in frequent 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 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 and/or defer spending, and aligning inventory to planned shipments and 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.

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

There have been public reports and announcements of a global semiconductor chip shortage that is anticipated to continue into at least early 2022. It is affecting companies across a wide range of industries, including some of our customers, which could temporarily impact the Company's revenue, volume, and profitability. 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 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 (ERC), 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 ERC. On March 1, 2021, the IRS released Notice 2021-20 to provide guidance on the original ERC, as modified by the Relief Act. During 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 June 30, 2021, as Tax Receivable, and as a credit to wages in the Statement of Operations during the six months ended June 30, 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. As of the March 11, 2021, passage of the American Rescue Plan Act, the ERC is available for all four quarters of 2021.

During the first quarter of 2021, we experienced a decline in gross receipts of 25% compared to the first quarter of 2019. This decline, along with continued underutilization of certain manufacturing equipment, reduction in employee's workloads, travel restrictions and supply chain issues, 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. These funds were received during the second quarter of 2021 and appear as a credit to wages in the Statement of Operations during the six months ended June 30, 2021. 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 were eligible for this credit for the second quarter of 2021 in the amount of $151,701, which appears as a credit to wages in the Statement of Operations for the three and six months ended June 30, 2021.

$80,448 was applied as a credit to payroll taxes throughout the second quarter and the remainder appears on the balance sheet as Tax Receivable as of June 30, 2021.

During the second quarter of 2021, we experienced a decline in gross receipts of 30% compared to the second quarter of 2019. This decline, along with continued underutilization of certain manufacturing equipment, reduction in employee's workloads, travel restrictions and supply chain issues, qualified us to receive this credit for the third quarter of 2021. As previously mentioned, an employer that has a decline in gross receipts 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 during the third quarter of 2021.

For the three months ended June 30, 2021, we had total revenue of $1,972,049. This was a decrease of $634,538 or 24.3%, compared to the three months ended June 30, 2020. For the six months ended June 30, 2021, we had total revenue of $4,994,359. This was a decrease of $1,051,023, or 17.4%, compared to the six months ended June 30, 2020. The decrease was principally due to lower pricing in the three and six months ended June 30, 2021, which was partially offset by higher volume and product mix.

Gross profit was $562,554 for the three months ended June 30, 2021, compared to $437,784 for the same three months in 2020 and $1,365,590 and $947,122 for the six months ended June 30, 2021, and 2020, respectively. This increase was due to volume, product mix, and improved manufacturing efficiency. In addition, $87,287 and $238,275 was related to the Employee Retention Credit for the three and six months ended June 30, 2021, respectively.

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

Operating expenses were $384,519, and $410,024 for the three months ended June 30, 2021, and 2020, respectively and $762,012 and $831,877 for the six months ended June 30, 2021, and 2020, respectively.

Income from operations was $178,035 and $27,760 for the three months ended June 30, 2021, and 2020, respectively, which included $151,701 related to the Employee Retention Credit during the second quarter of 2021. Income from operations was $603,578 and $115,245 for the six months ended June 30, 2021, and 2020, respectively, which included $407,207 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 and six months ended June 30, 2021 (unaudited) compared to three and six months ended June 30, 2020 (unaudited):

Revenue

For the three months ended June 30, 2021, we had total revenue of $1,972,049. This was a decrease of $634,538, or 24.3%, compared to the three months ended June 30, 2020. For the six months ended June 30, 2021, we had total revenue of $4,994,359. This was a decrease of $1,051,023, or 17.4%, compared to the six months ended June 30, 2020. These increases were principally due to lower pricing in 2021, which was partially offset by higher volume and product mix. We anticipate revenue to increase significantly during the third quarter of 2021 based on orders received during the first half of 2021.

Gross profit

Gross profit was $562,554 for the three months ended June 30, 2021, compared to $437,784 for the same three months in 2020. This was an increase of $124,770, or 28.5%. Gross profit as a percentage of revenue (gross margin) was 28.5% for the second quarter of 2021 compared to 16.8% for the same period in 2020. Gross profit was $1,365,590 for the six months ended June 30, 2021, compared to $947,122 for the first six months of 2020. This was an increase of $418,468 or 44.2%. Gross margin was 27.3% for the first six months of 2021 compared to 15.7% for the same period in 2020. These increases were due to volume, product mix, and improved manufacturing efficiency. In addition, $87,287 and $238,275 was related to the Employee Retention Credit for the three and six months ended June 30, 2021, respectively. While we expect revenue and gross profit to increase during the third quarter of 2021, it is anticipated that gross margin will decrease due to higher raw material cost.

General and administrative expense

General and administrative expense for the three months ended June 30, 2021, and 2020, was $283,708 and $272,216, respectively, an increase of 4.2%. General and administrative expense for the six months ended June 30, 2021, and 2020, was $571,589 and $555,381, respectively, an increase of 2.9%. Increase in compensation was offset by the Employee Retention Credit of $21,000 during the second quarter of 2021 and $57,000 for the six months ended June 30, 2021.

Included in general and administrative expense was $53,561 and $56,555 for professional fees for the three months ended June 30, 2021, and 2020, respectively and $124,759 and $120,137 for the six months ended June 30, 2021, and 2020, respectively. These continued expenses were primarily related to SEC compliance costs for legal, accounting and stockholder relations fees.

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

Research and development expense

Research and development expense for the three months ended June 30, 2021, was $54,377 compared to $90,421 for the same period in 2020, a decrease of 39.9%. Research and development expense for the six months ended June 30, 2021, was $92,596 compared to $177,325 for the same period in 2020, a decrease of 47.8%. This decrease is primarily related to the Employee Retention Credit of $22,750 during the second quarter of 2021 and $61,750 during the first six months of 2021. 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 $46,434 and $47,387 for the three months ended June 30, 2021, and 2020, respectively. This was a decrease of 2.0%. Compensation expense related to an increase in staff in 2021 was offset by the Employee Retention Credit of approximately $20,663.

Marketing and sales expense was $97,827 and $99,171 for the six months ended June 30, 2021, and 2020, respectively. This was a decrease of 1.4%. Higher outside consulting expense and compensation expense related to an increase in staff in 2021 were offset by the Employee Retention Credit of $50,183, as well as lower travel expense.

Stock compensation expense

Included in total expenses were noncash stock-based compensation costs of $8,675 and $31,182 for the three months ended June 30, 2021, and 2020, respectively, and $30,563 and $62,362 for the six months ended June 30, 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 $8,669 as of June 30, 2021, and will be recognized through 2023.

Interest

Interest expense was $9,014 for the three months ended June 30, 2021, and $7,300 for the three months ended June 30, 2020. Interest expense was $16,652 for the six months ended June 30, 2021, and $11,369 for the six months ended June 30, 2020. Lower interest income during the first half of 2021 resulted in an increase to overall interest expense.

Income taxes

Income tax expense was $47,473 and $0 for the three months ended June 30, 2021, and 2020, respectively, and $138,093 and $1,900 for the six months ended June 30, 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 half of 2021 that could affect its view of the future realization of deferred tax assets and determined that no valuation allowance was necessary at June 30, 2021, and the deferred tax asset was $888,315 at June 30, 2021.

Income applicable to common stock

Income applicable to common stock for the three months ended June 30, 2021, and 2020, was $115,510 and $14,422, respectively. Income applicable to common stock for the six months ended June 30, 2021, and 2020 was $762,057 and $89,900, respectively. The increase was primarily the result of higher gross profit and the Employee Retention Credit for the three and six months ended June 30, 2021, as well as forgiveness of the PPP Loan in the first quarter of this year.

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

Liquidity and Capital Resources

Cash

As of June 30, 2021, cash on hand was $3,497,202 compared to $2,917,551 at December 31, 2020, an increase of 19.9%.

Working capital

At June 30, 2021, working capital was $3,269,696 compared to $2,810,629 at December 31, 2020, an increase of $459,067, or 16.3%, primarily due to the increase in cash of $579,651.

Cash from operations

Net cash provided by operating activities during the six months ended June 30, 2021, was $1,249,462 and $8,818 for the six months ended June 30, 2020. This included depreciation and amortization of $273,688 and $266,486, and noncash stock-based compensation costs of $30,563 and $62,362 for the six months ended June 30, 2021, and 2020, respectively. Due to orders received during the first half of 2021, inventories increased $3,065,409, accrued expenses and customer deposits increased $3,477,435 and accounts payable increased $286,866.

Cash from investing activities

Cash of $558,828 and $167,999 was used in investing activities during the six months ended June 30, 2021, and June 30, 2020, respectively, for the acquisition of production equipment.

Cash from financing activities

Cash of $87,422 and $48,620 was used in financing activities for principal payments to third parties for finance lease obligations during the six months ended June 30, 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. Also, a dividend payment of $24,152 was made to owners of our Series B preferred stock during the second quarter of 2021 and 2020.

Debt outstanding

Total debt outstanding decreased to $316,212 at June 30, 2021, from $728,934 at December 31, 2020, a decrease of 56.6%. As previously mentioned, cash of $87,422 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, tax valuation allowance, 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. 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.
