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, some 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 whom we are still unable to visit in person.

Based on recent conversations with customers, we do not expect to experience any material impairments or changes in accounting judgements related to COVID-19. 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)

Two additional issues are affecting national and global market conditions. First, supply chain disruptions have become more frequent in recent months for the Company and some of its customers. Thus far, we have not experienced material adverse effects regarding product shipments; however, timely sourcing of certain materials is of increased concern. Second, published articles and corporate announcements continue to address the global semiconductor chip shortage, which is anticipated to continue into 2022. It is affecting some of our customers which could 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, 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 September 30, 2021, as Tax Receivable, and as a credit to wages in the Statement of Operations during the nine months ended September 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 nine months ended September 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 nine months ended September 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 were eligible for this credit for the third quarter of 2021 in the amount of $153,713, which appears as a credit to wages in the Statement of Operations for the three and nine months ended September 30, 2021. $73,852 was applied as a credit to payroll taxes throughout the third quarter and the remainder appears on the balance sheet as Tax Receivable as of September 30, 2021.

In addition, the American Rescue Plan Act of 2021 allows eligible employers with fewer than 500 employees to qualify for a tax credit for providing paid time off for each employee receiving COVID-19 vaccinations and for any time needed to recover from the vaccine. The Company received a credit of $11,042 and this amount appears as a credit to wages in the Statement of Operations for the three and nine months ended September 30, 2021.

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

For the three months ended September 30, 2021, we had record total revenue of $5,211,169. This was an increase of $3,717,091 or 248.8%, compared to the three months ended September 30, 2020. For the nine months ended September 30, 2021, we had total revenue of $10,205,528. This was an increase of $2,666,068, or 35.4%, compared to the nine months ended September 30, 2020. The increase was principally due to higher raw material pricing for the 2021 third quarter, in addition to increased volume and improved product mix throughout the first nine months of 2021 compared to a year ago.

Gross profit was a record $1,302,368 for the three months ended September 30, 2021, compared to $459,139 for the same three months in 2020 and $2,667,958 and $1,406,261 for the nine months ended September 30, 2021, and 2020, respectively. These increases were due to volume, product mix, and improved manufacturing efficiency. In addition, $90,082 and $328,356 was related to the ERC and ARP credits for the three and nine months ended September 30, 2021, respectively.

Operating expenses were $425,341 and $391,582 for the three months ended September 30, 2021, and 2020, respectively and $1,187,353 and $1,223,459 for the nine months ended September 30, 2021, and 2020, respectively.

Income from operations was $877,027 and $67,557 for the three months ended September 30, 2021, and 2020, respectively, which included $164,755 related to the ERC and ARP credits during the third quarter of 2021. Income from operations was $1,480,605 and $182,802 for the nine months ended September 30, 2021, and 2020, respectively, which included $571,962 related to the ERC and ARP credits during the first nine months of 2021.

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 nine months ended September 30, 2021 (unaudited) compared to three and nine months ended September 30, 2020 (unaudited):

Revenue

For the three months ended September 30, 2021, we had total record revenue of $5,211,169. This was an increase of $3,717,091 or 248.8%, compared to the three months ended September 30, 2020. For the nine months ended September 30, 2021, we had total revenue of $10,205,528. This was an increase of $2,666,068 or 35.4%, compared to the nine months ended September 30, 2020. The increase was principally due to higher raw material pricing in the 2021 third quarter, in addition to increased volume and improved product mix throughout the first nine months of 2021. During 2020, total revenue was adversely impacted by lower volume, pricing, and COVID-19 related issues. We anticipate revenue for the fourth quarter of 2021 to be below the 2021 third quarter amount, primarily due to lower raw material pricing. Volume is expected to remain stable during the 2021 fourth quarter compared to the third quarter of 2021.

Gross profit

Gross profit was a record $1,302,368 for the three months ended September 30, 2021, compared to $459,139 for the same three months in 2020. This was an increase of $843,229 or 183.7%. Gross profit as a percentage of revenue (gross margin) was 25.0% for the third quarter of 2021 compared to 30.7% for the same period in 2020. Gross profit was $2,667,958 for the nine months ended September 30, 2021, compared to $1,406,261 for the first nine months of 2020. This was an increase of $1,261,697 or 89.7%. Gross margin was 26.1% for the first nine months of 2021 compared to 18.7% for the same period in 2020. These increases were due to volume, product mix, and improved manufacturing efficiency. In addition, $90,082 and $328,356 was related to the ERC and ARP credits for the three and nine months ended September 30, 2021, respectively.

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

General and administrative expense

General and administrative expense for the three months ended September 30, 2021, and 2020, was $306,997 and $263,444, respectively, an increase of 16.5%. General and administrative expense for the nine months ended September 30, 2021, and 2020, was $878,586 and $818,825, respectively, an increase of 7.3%. Increase in compensation, including year-end accruals, was partially offset by the ERC and ARP credits of $22,354 during the third quarter of 2021 and $79,354 for the nine months ended September 30, 2021.

Professional fees

Included in total expense was $44,385 and $39,694 for professional fees for the three months ended September 30, 2021, and 2020, respectively and $169,143 and $159,831 for the nine months ended September 30, 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 September 30, 2021, was $56,612 compared to $83,276 for the same period in 2020, a decrease of 32.0%. Research and development expense for the nine months ended September 30, 2021, was $149,208 compared to $260,601 for the same period in 2020, a decrease of 42.7%. This decrease was primarily related to the ERC and ARP credits of $29,224 during the third quarter of 2021 and $90,974 during the first nine 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 $61,732 and $44,862 for the three months ended September 30, 2021, and 2020, respectively. This was an increase of $16,870 or 37.6%. Compensation expense related to an increase in staff in 2021 was offset by the ERC and ARP credits of $23,095. Travel expenses were up slightly as we were able to attend one tradeshow, but some tradeshows have been cancelled or moved to virtual, including some scheduled for the fourth quarter of 2021. We continue to maintain regular contact, via phone and other electronic means, with other customers and suppliers whom we are still unable to visit in person due to the ongoing COVID-19 pandemic.

Marketing and sales expense was $159,559 and $144,033 for the nine months ended September 30, 2021, and 2020, respectively. This was an increase of 10.8%. Higher outside consulting expense and compensation expense related to an increase in staff in 2021 were partially offset by the ERC and ARP credits of $73,278.

Stock compensation expense

Included in total expenses were non-cash stock-based compensation costs of $8,670 and $31,182 for the three months ended September 30, 2021, and 2020, respectively, and $39,233 and $93,544 for the nine months ended September 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 $7,487 as of September 30, 2021, and will be recognized through 2023.

Interest

Interest expense was $8,156 and $9,058 for the three months ended September 30, 2021, and 2020, respectively. Interest expense was $24,808 and $20,427 for the nine months ended September 30, 2021, and 2020, respectively. Lower interest income during 2021 resulted in an increase to overall interest expense.

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

Income taxes

Income tax expense was $200,189 and $0 for the three months ended September 30, 2021, and 2020, respectively, and $338,282 and $1,900 for the nine months ended September 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 nine months of 2021 that could affect its view of the future realization of deferred tax assets and determined that no valuation allowance was necessary at September 30, 2021, and the deferred tax asset was $703,132 at September 30, 2021.

Income applicable to common shares

Income applicable to common shares for the three months ended September 30, 2021, and 2020, was $662,644 and $52,461, respectively. Income applicable to common shares for the nine months ended September 30, 2021, and 2020 was $1,424,701 and $142,361, respectively. These increases were primarily the result of higher revenue, improved gross profit, and the Employee Retention Credit for the three and nine months ended September 30, 2021, as well as forgiveness of the PPP Loan in the first quarter of this year.

Liquidity and Capital Resources

Cash

As of September 30, 2021, cash on hand was $3,953,385 compared to $2,917,551 at December 31, 2020, an increase of 35.5%.

Working capital

At September 30, 2021, working capital was $4,152,431 compared to $2,810,629 at December 31, 2020, an increase of $1,341,802, or 47.7%, primarily due to the increase in cash of $1,035,834.

Cash from operations

Net cash provided by operating activities during the nine months ended September 30, 2021, was $1,780,698 and $504,561 for the nine months ended September 30, 2020. This included depreciation and amortization of $329,104 and $338,616 and non-cash stock-based compensation costs of $39,233 and $93,544 for the nine months ended September 30, 2021, and 2020, respectively. In addition, due to orders received throughout 2021, accrued expenses and customer deposits increased $887,869, inventory increased $801,669, accounts receivable increased $298,706 and accounts payable increased $165,371.

Cash from investing activities

Cash of $615,088 and $49,023 was used in investing activities during the nine months ended September 30, 2021, and 2020, respectively, for the acquisition of production equipment.

Cash from financing activities

Cash of $123,715 and $84,238 was used in financing activities for principal payments to third parties for finance lease obligations during the nine months ended September 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 $279,919 at September 30, 2021, from $728,934 at December 31, 2020, a decrease of 61.6%. As previously mentioned, cash of $123,715 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.
