NOTES TO CONDENSED FINANCIAL STATEMENTS

FOR THE PERIOD ENDED JUNE 30, 2020

(in thousands except share and per share amounts)

(unaudited)

Note 1. Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions and regulations of the Securities and Exchange Commission to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.

This report should be read together with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, including the audited financial statements and footnotes therein.

Management believes that the unaudited financial statements include all adjustments, consisting of normal recurring accruals, necessary to fairly state the financial position and results of operations as of June 30, 2020 and for the three and six-month periods ended June 30, 2020 and 2019,  in accordance with accounting principles generally accepted in the United States of America. The results of interim periods may not be indicative of results to be expected for the year.

Nature of Business

Electro-Sensors, Inc. manufactures and markets a complete line of monitoring and control systems for a variety of industrial machinery. The Company uses leading-edge technology to continuously improve its products, with the ultimate goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturers’ representatives, and distributors to a wide variety of industries that use the products in a variety of applications to monitor process machinery operations. The Company markets its products to customers located throughout the United States, Canada, Latin America, Europe, and Asia.

Revenue Recognition

At contract inception, the Company assesses the goods and services promised to a customer and identifies a performance obligation for each distinct promised good or service. We also determine the transaction price for each performance obligation at contract inception. Our contracts, generally in the form of a purchase order, specify the product or service that is promised to the customer. The typical contract life is less than one month and contains a single performance obligation, to provide conforming goods or services to the customer. On some contracts, we have a second performance obligation, which typically is the initialization of the HazardPRO^TM product. For contracts that have multiple performance obligations, we allocate the transaction price to each performance obligation using the relative stand-alone selling price. We generally determine stand-alone selling prices based on the observable stand-alone prices charged to customers. We recognize product revenue at the point in time when control of the product is transferred to the customer, which typically occurs when we ship the products. We recognize service revenue at the point in time when we have provided the service. 

Fair Value Measurements 

The carrying value of trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2020 and December 31, 2019, due to the short maturity nature of these instruments.

Intangibles

Intangible assets are comprised of the HazardPRO technology and a technology license.  The Company amortizes the cost of these intangible assets on a straight-line method over their estimated useful lives.

Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected option life, and the expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2020, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next three years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, stock compensation expense, and the potential estimated impact on operations due to the COVID-19 pandemic as it relates to disruptions to our supply chain and customer demand. It is at least reasonably possible that these estimates may change in the near term.

Net Income (Loss) per Common Share

Basic and diluted net income (loss) per common share is determined by dividing net income (loss) attributable to common stockholders by the weighted-average common shares outstanding during the period. For the three and six month periods ended June 30, 2020 and 2019, 332,500 weighted average common shares for underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted income (loss) per common shares are the same.

Forward-looking statements include, but are not limited to, statements about the success of our marketing efforts; our efforts to accelerate future growth or income; our business development activities; our efforts to maintain or reduce production costs; our expected use of cash on hand; our cash requirements; and the sufficiency of our cash flows. Any statement that is not based solely upon historical facts, including our strategies for the future and the outcome of events that have not yet occurred, is a forward-looking statement.

All forward-looking statements in this document are based on information available to us as of the date of this Form 10-Q, and we assume no obligation to update any of these forward-looking statements, other than as required by law. Our actual results could differ materially from those projected or indicated in these forward-looking statements. These forward-looking statements are subject to certain risks and uncertainties that could cause future results to differ materially from our recent results or those projected in the forward-looking statements, including the accuracy of management’s assumptions with respect to industry trends, fluctuations in industry conditions, the accuracy of management’s assumptions regarding expenses and our cash needs and those listed under the heading “Cautionary Statements” under “Item 1—Business,” in our Annual Report on Form 10-K for the year ended December 31, 2019, as any effect that the COVID-19 pandemic may have on the efficiency of our business operations, our customer base and he domestic or worldwide economy.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make decisions based upon estimates, assumptions, and factors it considers relevant to the circumstances. These decisions include the selection of applicable accounting principles and the use of judgment in their application and affect reported amounts and disclosures. Changes in economic conditions or other business circumstances may affect the outcomes of management’s estimates and assumptions. An in-depth description of our accounting estimates can be found in the interim financial statements included in this report and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. We have not developed new estimates subsequent to those discussed in our Annual Report.

The following paragraphs discuss the Company’s performance for the three and six months ended June 30, 2020 and 2019.

RESULTS OF OPERATIONS (in thousands) 

Net Sales

Net sales for the three-month period ended June 30, 2020 were $2,092, a decrease of $168, or 7.4%, from $2,260 during the comparable period in 2019.  Net sales for the six months ended June 30, 2020 were $4,015, a decrease of $253, or 5.9%, over the same period in 2019. The second calendar quarter of 2020 represents the first full quarter impacted by the COVID-19 pandemic, and we believe much of the revenue decrease during the period relates to reduced spending by our customers due to the impact of the pandemic on their business.  While customers continued to place orders for smaller projects and maintenance items; many larger capital projects have been paused due to continued uncertainty surrounding the pandemic and its related effects.

Gross Profit

Gross profit for the second quarter of 2020 decreased $137, or 11.1%, over the same period in 2019. Gross profit for the six months ended June 30, 2020 decreased $205, or 8.9%, over the same period in 2019. Gross margin decreased in the second quarter of 2020 to 52.5% from 54.6% during the same period in 2019. Gross margin for the six months ended June 30, 2020 decreased to 52.2% from 53.9% over the same period in 2019.The decrease in gross margin percentage for both periods was primarily due to a change in product mix and higher material costs largely driven by the increase in government tariff charges that began to be assessed during the second half of 2019.

Total operating expenses decreased $68, or 5.9%, for the second quarter of 2020 compared to the same period in 2019, but increased as a percentage of net sales to 51.6% from 50.7%. Total operating expenses decreased $81, or 3.5%, for the six months ended June 30, 2020 compared to the same period in 2019, but increased as a percentage of net sales to 55.2% from 53.9%. 

● Selling and marketing expenses in the second quarter of 2020 decreased $73, or 14.1%, from the same period in 2019 and decreased as a percentage of net sales to 21.2% from 22.8%. Selling and marketing expenses in the six months ended June 30, 2020 decreased $100, or 10.0%, from the same period in 2019 and decreased as a percentage of net sales to 22.4% from 23.4%. The decrease in the second quarter resulted primarily from lower outside sales representative compensation due to changes in commission plans and decreased net sales and a decrease in travel expenses due to the COVID-19 pandemic.  The decrease in the six months resulted primarily from lower outside sales representative compensation due to changes in commission plans, decreased net sales, and fewer manufacturer representatives and decreases in travel and trade show expenses due to cancelled shows both due to the COVID-19 pandemic.

● General and administrative expenses increased $22, or 5.3%, for the second quarter of 2020 compared to the same period in 2019 and increased as a percentage of net sales to 21.0% from 18.5%. General and administrative expenses increased $15, or 1.7%, for the six months ended June 30, 2020 compared to the same period in 2019 and increased as a percentage of net sales to 22.5% from 20.9%. The increase in the second quarter was due primarily to amortization of the communication technology that began in October 2019 and higher legal fees. The increase for the six months was due primarily to the noted amortization and legal fees, partially offset by decreased expenses related to computer supplies, software, and training. 

● Research and development expenses decreased $17, or 8.0%, in the second quarter of 2020 from the same period in 2019 and was unchanged as a percentage of net sales at 9.4%. Research and development expenses increased $4, or 1.0%, in the six months ended June 30, 2020 from the same period in 2019 and increased as a percentage of net sales to 10.3% from 9.6%. The decrease for the quarter was due to lower contract engineering costs related to product enhancements.  The increase for the six months was due to third party product certification costs, partially offset by lower 2020 contract engineering costs related to product enhancements.

Non-Operating Income (Net)

Net non-operating income decreased by $43, or 100.0%, for the second quarter of 2020 compared to the same period in 2019. Net non-operating income decreased by $58, or 65.2%, for the six months ended of June 30, 2020 compared to the same period in 2019.  The decrease in both periods was primarily a result of less interest income earned as a result of lower interest rates on Treasury Bills.

Income (Loss) Before Income Tax Expense (Benefit)

Income before income tax expense was $19 for the second quarter of 2020, representing a decrease of $112, or 85.5%, compared to $131 for the same period in 2019. Loss before income tax benefit was $91 for the six months ended June 30, 2020, representing a decrease of $182, or 200.0%, compared to an income before income tax expense of $91 for the same period in 2019. The decrease for both periods was primarily the result of the lower net sales and higher cost of sales discussed above.

Income Tax Benefit

The Company's income tax expense decreased to $1, or 0.0% of net sales, in the second quarter of 2020 compared to an expense of $28, or 1.2% of net sales, in the second quarter of 2019. The Company's income tax benefit was $18, or 0.4% of net sales, for the six months ended June 30, 2020 compared to an expense of $19, or 0.4% of net sales, for the six months ended June 30, 2019.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $2,262 at June 30, 2020 and $8,785 at December 31, 2019. The decrease was primarily the result of cash used to purchase treasury bills considered as available-for-sale securities.  At December 31, 2019, all of the treasury bills were reported as cash equivalents and as of June 30, 2020, all but one of the treasury bills were reported as investments.

Cash generated from operating activities was $240 for the six months ended June 30, 2020 as compared to cash used in operating activities of $52 for the six months ended June 30, 2019. The $292 increase in cash generated from operations was due to a decrease in trade receivables partially offset by an increase in accounts payable. The decrease in trade receivables was due to decreased net sales and the timing of collections on accounts.  The increase in accounts payable was due to timing of inventory purchases and vendor payments.  

Cash used in investing activities was $6,760 for the six months ended June 30, 2020 as compared to cash generated from investing activities of $23 for the six months ended June 30, 2019. During the six months ended June 30, 2020, the Company had net purchases of treasury bills of $6,748 compared to net proceeds from maturities of treasury bills of $84 during the six months ended June 30, 2019. In addition, the Company purchased $12 and $61 of property and equipment during the six months ended June 30, 2020 and June 30, 2019, respectively.

Cash used in financing activities in the six months ended June 30, 2020 and 2019 was $3. The cash used in both periods was for principal payments on a financing lease on right-to-use assets.  In addition, during the second quarter of 2020, the Company received and subsequently repaid a Payroll Protection Loan of $645 from the Small Business Administration, as discussed in the next paragraph.

As previously disclosed, on May 5, 2020, we entered into a U.S. Small Business Administration Paycheck Protection Program promissory note in the principal amount of $645 (the “PPP Loan”). The PPP Loan was unsecured and was evidenced by a note in favor of US Bank National Association as the lender. Subsequent to receipt of the loan, our Board of Directors continued to monitor both our ongoing performance and the routinely issued clarifying guidance provided by the government. As a result of this analysis, the Board determined that given the strength of our operations and the government issued clarifications, we would repay the entire amount of the PPP Loan. We repaid the PPP Loan in full on June 4, 2020. There were no prepayment penalties in connection with this voluntary repayment.

Subject to the following section, the Company believe its ongoing cash requirements will be primarily for capital expenditures, research and development, working capital, and growth initiatives. Management believes that our cash on hand and any cash generated from operations will be sufficient to meet our cash requirements through at least the next 12 months.

COVID-19 Pandemic Discussion

As a result of the COVID-19 pandemic, we experienced weaker than anticipated performance in the first and second quarters of 2020.  Due to the ongoing uncertainty about the severity and duration associated with the COVID-19 pandemic, we considered furloughing or eliminating employees and taking other measures to reduce operating costs until there was more certainty about the short-term and long-term effects of the COVID-19 pandemic on the nation’s economy and the Company’s business.

As of the end of July 2020, however, we have not furloughed any employees.  We expect our third quarter financial results to continue to be negatively affected, potentially to a material degree, as the effects of the pandemic continue to permeate the economy.  Reductions in net sales have not been offset by a proportional decrease in expense, as we continue to incur cost related to employee compensation and operating expenses, resulting in a negative effect on the relationship between our costs and net sales.  

We believe the pandemic will continue to slow larger orders as customers delay projects in order to conserve cash, which will weaken the demand for our products. 

We, typically, have multiple sources for components.  Although we have experienced some extended delivery times as vendors have difficulty sourcing components, we continue to believe we have adequate sources for our key components to meet anticipated demand.

As of the date of this filing, we expect our business will continue to be negatively affected, but cannot currently determine the significance and duration of the pandemic on our business.

Future Business Development Activities

The Company continues to seek growth opportunities, both internally through the Company’s existing portfolio of products, technologies and markets, as well as externally through technology partnerships or related-product acquisitions. 

Off-balance Sheet Arrangements

As of June 30, 2020, the Company had no off-balance sheet arrangements or transactions.

Basis of Presentation [Abstract]

Basis of Presentation

Note 1. Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions and regulations of the Securities and Exchange Commission to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.

This report should be read together with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, including the audited financial statements and footnotes therein.

Management believes that the unaudited financial statements include all adjustments, consisting of normal recurring accruals, necessary to fairly state the financial position and results of operations as of June 30, 2020 and for the three and six-month periods ended June 30, 2020 and 2019,  in accordance with accounting principles generally accepted in the United States of America. The results of interim periods may not be indicative of results to be expected for the year.

Nature of Business

Electro-Sensors, Inc. manufactures and markets a complete line of monitoring and control systems for a variety of industrial machinery. The Company uses leading-edge technology to continuously improve its products, with the ultimate goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturers’ representatives, and distributors to a wide variety of industries that use the products in a variety of applications to monitor process machinery operations. The Company markets its products to customers located throughout the United States, Canada, Latin America, Europe, and Asia.

Revenue Recognition

At contract inception, the Company assesses the goods and services promised to a customer and identifies a performance obligation for each distinct promised good or service. We also determine the transaction price for each performance obligation at contract inception. Our contracts, generally in the form of a purchase order, specify the product or service that is promised to the customer. The typical contract life is less than one month and contains a single performance obligation, to provide conforming goods or services to the customer. On some contracts, we have a second performance obligation, which typically is the initialization of the HazardPRO^TM product. For contracts that have multiple performance obligations, we allocate the transaction price to each performance obligation using the relative stand-alone selling price. We generally determine stand-alone selling prices based on the observable stand-alone prices charged to customers. We recognize product revenue at the point in time when control of the product is transferred to the customer, which typically occurs when we ship the products. We recognize service revenue at the point in time when we have provided the service. 

Fair Value Measurements 

The carrying value of trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2020 and December 31, 2019, due to the short maturity nature of these instruments.

Intangibles

Intangible assets are comprised of the HazardPRO technology and a technology license.  The Company amortizes the cost of these intangible assets on a straight-line method over their estimated useful lives.

Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected option life, and the expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2020, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next three years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, stock compensation expense, and the potential estimated impact on operations due to the COVID-19 pandemic as it relates to disruptions to our supply chain and customer demand. It is at least reasonably possible that these estimates may change in the near term.

Net Income (Loss) per Common Share

Basic and diluted net income (loss) per common share is determined by dividing net income (loss) attributable to common stockholders by the weighted-average common shares outstanding during the period. For the three and six month periods ended June 30, 2020 and 2019, 332,500 weighted average common shares for underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted income (loss) per common shares are the same.

The fair value of the commercial paper and treasury bills is based on quoted market prices in an active market. There is no public market for the available-for-sale equity security owned by the Company. The Company has determined the fair value for this equity security based on financial and other factors that are considered level 3 inputs in the fair value hierarchy.  

The change in level 3 assets at fair value on a recurring basis are as follows:

Nature of Business

Nature of Business

Electro-Sensors, Inc. manufactures and markets a complete line of monitoring and control systems for a variety of industrial machinery. The Company uses leading-edge technology to continuously improve its products, with the ultimate goal of manufacturing the industry-preferred product for every market served. The Company sells these products through an internal sales staff, manufacturers’ representatives, and distributors to a wide variety of industries that use the products in a variety of applications to monitor process machinery operations. The Company markets its products to customers located throughout the United States, Canada, Latin America, Europe, and Asia.

Revenue Recognition

Revenue Recognition

At contract inception, the Company assesses the goods and services promised to a customer and identifies a performance obligation for each distinct promised good or service. We also determine the transaction price for each performance obligation at contract inception. Our contracts, generally in the form of a purchase order, specify the product or service that is promised to the customer. The typical contract life is less than one month and contains a single performance obligation, to provide conforming goods or services to the customer. On some contracts, we have a second performance obligation, which typically is the initialization of the HazardPRO^TM product. For contracts that have multiple performance obligations, we allocate the transaction price to each performance obligation using the relative stand-alone selling price. We generally determine stand-alone selling prices based on the observable stand-alone prices charged to customers. We recognize product revenue at the point in time when control of the product is transferred to the customer, which typically occurs when we ship the products. We recognize service revenue at the point in time when we have provided the service. 

Fair Value Measurements

Fair Value Measurements 

The carrying value of trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2020 and December 31, 2019, due to the short maturity nature of these instruments.

Intangibles

Intangibles

Intangible assets are comprised of the HazardPRO technology and a technology license.  The Company amortizes the cost of these intangible assets on a straight-line method over their estimated useful lives.

Stock-Based Compensation

Stock-Based Compensation

The Company records compensation expense for stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes-Merton (“BSM”) option pricing model. The Company uses historical data, among other factors, to estimate the expected price volatility, the expected option life, and the expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. 

As of June 30, 2020, there was approximately $11 of unrecognized compensation expense related to unvested stock options. The Company expects to recognize this expense over the next three years.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of economic lives of long-lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, stock compensation expense, and the potential estimated impact on operations due to the COVID-19 pandemic as it relates to disruptions to our supply chain and customer demand. It is at least reasonably possible that these estimates may change in the near term.

Net Income (Loss) per Common Share

Net Income (Loss) per Common Share

Basic and diluted net income (loss) per common share is determined by dividing net income (loss) attributable to common stockholders by the weighted-average common shares outstanding during the period. For the three and six month periods ended June 30, 2020 and 2019, 332,500 weighted average common shares for underlying stock options have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares outstanding used to calculate both basic and diluted income (loss) per common shares are the same.
