Executive Summary

For the three months ended March 31, 2023, we had total revenue of $5,797,147 compared to $5,326,432 for the three months ended March 31, 2022. Higher volume was the key factor that contributed to the increase, despite lower raw material costs compared to the same period last year.

Gross profit was $1,324,597 for the three months ended March 31, 2023 compared to $994,101 for the same three months in 2022. The increase was due to higher revenue and favorable product mix.

Operating expenses were $677,344, and $542,407 for the three months ended March 31, 2023 and 2022, respectively.

Income from operations was $647,253 and $451,694 for the three months ended March 31, 2023 and 2022, respectively.

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 presses, 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 involve research and development expense to accelerate time to market.

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 remains at historically high levels, impacting labor, 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 in 2023. 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, including identifying additional suppliers and adapting to our customers' specific circumstances and forecasts.

RESULTS OF OPERATIONS

Three months ended March 31, 2023 (unaudited) compared to three months ended March 31, 2022 (unaudited):

Revenue

For the three months ended March 31, 2023, we had revenue of $5,797,147. This was an increase of $470,715, compared to the three months ended March 31, 2022. Higher volume was the key factor that contributed to the increase, despite lower raw material costs compared to the same period last year.

Gross profit

Gross profit was $1,324,597 for the three months ended March 31, 2023, compared to $994,101 for the same three months in 2022, an increase of $330,496. The increase was due to higher revenue and favorable product mix. Gross profit as a percentage of revenue (gross margin) was 22.8% for the first quarter of 2023 compared to 18.7% for the first quarter of 2022. The improved gross margin in 2023 was due to product mix and lower raw material costs.

General and administrative expense

General and administrative expense for the three months ended March 31, 2023 and 2022, was $432,413, and $373,188, respectively, an increase of 15.9%. This increase was attributed to higher compensation of $42,119, an increase in business liability insurance (due to higher revenue) of $12,938, and professional fees, primarily related to SEC compliance costs for legal, accounting and stockholder relations fees, of $7,328.

Research and development expense

Research and development expense for the three months ended March 31, 2023, was $135,360 compared to $87,031 for the same period in 2022, an increase of 55.5%. This increase was attributed to higher compensation of $19,121, outside consulting of $16,789 and materials and supplies of $12,614. 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 $109,571 and $82,188 for the three months ended March 31, 2023, and 2022, respectively. This was an increase of 33.3%. Compensation expense and travel expense increased $17,525 and $9,225 during the three months ended March 31, 2023, and 2022, respectively. We exhibited at a major international photonics trade show for the first time during the first quarter of 2023.

Stock compensation expense

Included in total expenses were noncash stock-based compensation costs of $45,090 and $23,299 for the three months ended March 31, 2023 and 2022, 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 $394 as of March 31, 2023 and will be recognized through April of 2023.

Interest

Interest income was $48,977, for the three months ended March 31, 2023. Interest expense was $6,493 for the three months ended March 31, 2022. The improvement was due to our approximately $2.0 million investment in marketable securities and the overall increase in interest rates. Interest expense has decreased as we continue to reduce our debt outstanding.

Income taxes

Income tax expense was $158,210, and $60,800 for the three months ended March 31, 2023, and 2022, respectively. At December 31, 2022, the deferred tax asset was $151,164. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Accordingly, management determined that no valuation allowance was necessary, and the deferred tax asset was $34,231 at March 31, 2023.

Net income

Net income for the three months ended March 31, 2023, and 2022, was $538,020, and $384,401, respectively. The increase was primarily the result of higher revenue, gross profit and interest income partially offset by higher operating and income tax expenses.

Liquidity and Capital Resources

Cash

As of March 31, 2023, cash on hand was $4,495,169 compared to $3,947,966 at December 31, 2022 due to net cash provided by operating activities in conjunction with investment in our manufacturing footprint and acquisition of production equipment.

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, 2022, 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 and current expected credit losses, 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 creditworthiness 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.
