Executive Summary

For the six months ended June 30, 2022, we had record total revenue of $11,831,437. Higher pricing, primarily attributable to increased raw material costs, higher volume and product mix were key factors that contributed to the increase.

Gross profit was $2,371,769 for the six months ended June 30, 2022 compared to $1,365,590 for the same six months in 2021. The increase was due to higher volume, favorable product mix, and improved manufacturing efficiency. The first half of 2021 included a reduction of expenses of approximately $238,000 related to the Employee Retention Credit ("ERC") enacted in 2020.

Operating expenses were $1,166,033 and $762,012 for the six months ended June 30, 2022 and 2021, respectively. The first six months of 2021 included a reduction of expenses of approximately $169,000 related to the ERC.

Income from operations was $1,205,736 and $603,578 for the six months ended June 30, 2022 and 2021, respectively.

We expect to receive shipment of additional manufacturing equipment during the third quarter of 2022. This includes a hot press that will enable production of higher temperature materials with increased capacity. A final cash payment of $220,075 was made for the hot press during late July of this year.

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. Based on ongoing conversations with customers, we do not expect to experience any material impairments or changes in accounting judgements related to COVID-19. We continue to follow practical safety procedures as needed. During the first half of 2022, we resumed in-person meetings, participated onsite in industry trade shows, and continue to maintain regular contact, via phone and other electronic means, with all customers and suppliers.

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

Several issues continue to affect national and global market conditions. First, inflation has accelerated, impacting raw material costs and transportation expenses. We have generally been able to pass on these increases to customers but are unable to predict how future or sustained inflationary pressure may impact our results. Second, supply chain disruptions are adversely impacting customers in certain markets. Thus far, we have not experienced material adverse effects regarding product shipments; however, timely deliveries and sourcing of certain materials is of increased concern. Third, published articles and corporate announcements continue to address the global semiconductor chip shortage, which is anticipated to continue at least into the fourth quarter of 2022. This shortage is affecting some of our customers which could impact the Company's revenue, volume, and profitability. Fourth, there are increased political uncertainties affecting global markets. Although we currently have no customers or vendors in Russia or Ukraine, we continue to monitor the situation as some raw material comes from Russia for the PVD industry. 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 and appears as gain on extinguishment of debt in the Statements of Income during the six months ended June 30, 2021.

The Employee Retention Credit ("ERC"), as originally enacted on March 27, 2020, by the CARES Act, was a refundable tax credit against certain employment taxes equal to 50% of the qualified wages an eligible employer paid 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 sheets as of June 30, 2022 and December 31, 2021, as Tax Receivable, and as a credit to wages in the Statements of Income during the six months ended June 30, 2021.

The Relief Act extended and enhanced the ERC 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 paid 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 was available for all four quarters of 2021. However, the Infrastructure Investment and Jobs Act enacted on November 15, 2021, ended the ERC effective September 30, 2021.

During the first and second quarter of 2021, we were qualified to receive the ERC. The ERC of $150,507 and $151,701 on qualified wages paid in the first and second quarter of 2021, respectively, appears as a credit to wages in the Statements of Income.

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 increased production and 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 specialty bonding processes for Aerospace customers. Those products continue to require research and development expense to accelerate time to market.

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

RESULTS OF OPERATIONS

Three and six months ended June 30, 2022 (unaudited) compared to three and six months ended June 30, 2021 (unaudited):

Revenue

For the three months ended June 30, 2022, we had record total revenue of $6,505,005. This was an increase of $4,532,956 compared to the three months ended June 30, 2021. For the six months ended June 30, 2022, we had record total revenue of $11,831,437. This was an increase of $6,837,078 compared to the six months ended June 30, 2021. Higher pricing, primarily attributable to increased raw material costs, higher volume and product mix were key factors that contributed to the increase.

Gross profit

Gross profit was $1,377,668 for the three months ended June 30, 2022, compared to $562,554 for the same three months in 2021, an increase of $815,114. Gross profit as a percentage of revenue (gross margin) was 21.2% for the second quarter of 2022 compared to 28.5% for the same period in 2021. Gross profit was $2,371,769 for the six months ended June 30, 2022, compared to $1,365,590 for the first six months of 2021, an increase of $1,006,179. Gross margin was 20.0% for the first six months of 2022 compared to 27.3% for the same period in 2021.

The increases in gross profit were due to higher revenue during 2022. The Employee Retention Credit (ERC) reduced cost of revenue in the three and six months ended June 30, 2021, by approximately $87,000 and $238,000, respectively. The lower gross margin in 2022 compared to a year ago was due to higher raw material costs in the first half of 2022.

General and administrative expense

General and administrative expense for the three months ended June 30, 2022, and 2021, was $423,401 and $283,708, respectively, an increase of 49.2%. General and administrative expense for the six months ended June 30, 2022, and 2021, was $796,589 and $571,589, respectively, an increase of 39.4%. During 2022 there was an increase in staff resulting in higher compensation of approximately $44,000. Business liability insurance (due to higher revenue) and professional fees, primarily related to SEC compliance costs for legal, accounting and stockholder relations fees, increased approximately $59,000. The three and six months ended June 30, 2021 included the ERC of $21,000 and $57,000, respectively.

Research and development expense

Research and development expense for the three months ended June 30, 2022, was $92,085 compared to $54,377 for the same period in 2021, an increase of 69.3%. Research and development expense for the six months ended June 30, 2022, was $179,116 compared to $92,596 for the same period in 2021, an increase of 93.4%. The ERC of $22,750 and $61,750 was included in the three and six months ended June 30, 2021, respectively. 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 $108,140 and $46,434 for the three months ended June 30, 2022, and 2021, respectively. This was an increase of 132.9%. Marketing and sales expense was $190,328 and $97,827 for the six months ended June 30, 2022, and 2021, respectively, an increase of 94.6%.

Travel expenses increased approximately $22,000 and $39,000 during the three and six months ended June 30, 2022, respectively, versus the same periods in 2021, as we resumed in-person meetings with some customers and participated onsite in industry trade shows. The three and six months ended June 30, 2021, included the ERC of approximately $21,000 and $50,000, respectively.

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

Stock compensation expense

Included in total expenses were noncash stock-based compensation costs of $8,673 and $8,675 for the three months ended June 30, 2022, and 2021, respectively, and $31,972 and $30,563 for the six months ended June 30, 2022, and 2021, 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 $3,941 as of June 30, 2022 and will be recognized through 2023.

Interest

Interest expense was $5,769 for the three months ended June 30, 2022, and $9,014 for the three months ended June 30, 2021. Interest expense was $12,262 for the six months ended June 30, 2022, and $16,652 for the six months ended June 30, 2021. The decrease was due to final payments of multiple finance leases during 2021.

Income taxes

Income tax expense was $83,400 and $47,473 for the three months ended June 30, 2022, and 2021, respectively, and $144,200 and $138,093 for the six months ended June 30, 2022, and 2021, respectively. At December 31, 2021, the deferred tax asset was $663,820. Management considered new evidence, both positive and negative, during the first half of 2022 that could affect its view of the future realization of deferred tax assets and determined that no valuation allowance was necessary, and the deferred tax asset was $531,720 at June 30, 2022.

Income applicable to common stock

Income applicable to common stock for the three months ended June 30, 2022, and 2021, was $664,873 and $115,510, respectively. Income applicable to common stock for the six months ended June 30, 2022, and 2021, was $1,049,274 and $762,057, respectively. The increase was primarily the result of higher revenue and gross profit.

Liquidity and Capital Resources

Cash

As of June 30, 2022, cash on hand was $5,409,210 compared to $4,140,942 at December 31, 2021. The increase was principally due to record total revenue and higher gross profit for the first six months of 2022.

Working capital

At June 30, 2022 working capital was $5,085,961 compared to $3,907,135 at December 31, 2021, an increase of $1,178,826 or 30.2%. Cash increased $1,268,268, receivables increased $287,692, inventories increased $2,544,430, customer deposits increased $2,137,883, while prepaid expenses decreased $632,305.

In addition to the net income generated, this included depreciation and amortization of $249,992 and $273,688, and noncash stock-based compensation costs of $31,972 and $30,563 for the six months ended June 30, 2022, and 2021, respectively.

The decrease in prepaid expenses was related to the receipt of inventory paid for in December 2021 and received in January 2022. Inventories and customer deposits increased due to orders received late in 2021 and throughout the first six months of 2022.


                                       16

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

Cash from investing activities

Cash of $179,140 and $558,828 was used in investing activities during the six months ended June 30, 2022, and June 30, 2021, respectively, for the acquisition of production equipment.

Cash from financing activities

Cash of $47,824 and $87,422 was used in financing activities for principal payments to third parties for finance lease obligations during the six months ended June 30, 2022, and 2021, respectively. The decrease was due to final payments of multiple finance leases during 2021. A cash dividend payment of $24,152 was made to owners of our Series B preferred stock during the six months ended June 30, 2021.

Debt outstanding

Total debt outstanding was $195,392 at June 30, 2022, compared to $243,218 at December 31, 2021, a decrease of 19.7%. As previously mentioned, cash of $47,824 was used for principal payments for finance lease obligations during 2022.

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, 2021, 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.
