FOR THE PERIOD ENDED JUNE 30, 2016

(in thousands except share and per share amounts)

(unaudited)

Note 1. Basis of Presentation

The accompanying unaudited consolidated 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, 2015, including the audited consolidated 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, 2016 and for the three and six-month periods then ended 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 and make them easier to use, 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.

Fair Value Measurements

The carrying value of cash equivalents, treasury bills, trade receivables, accounts payable, and other financial working capital items approximates fair value at June 30, 2016 and December 31, 2015, due to the short maturity nature of these instruments.

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.

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 consolidated 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, contingent earn-out, and stock compensation expense. It is at least reasonably possible that these estimates may change in the near term.

The fair value of the money market funds, commercial paper and treasury bills is based on quoted market prices in an active market. The available-for-sale security is a limited-marketable company. There is an insignificant market for the limited-marketable company and the Company has determined its value based on financial and other factors, which are considered level 3 inputs in the fair value hierarchy. Management estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent earn-out, which is considered a level 3 input in the fair value hierarchy.

The change in level 3 liabilities at fair value on a recurring basis is summarized as follows:

	Period Ended June 30,
	2016			2015
Beginning Balance	$	455		$	472
Credit to earnings		(72	)		(17	)
Ending Balance	$	383		$	455

The decrease in the contingent liability reflects the Company’s expectation of moderately lower future contingent payments throughout the four year earn-out period.

Note Payable – Long Term	$	0

Note 5. Stock-Based Compensation

During the first quarter of 2016, the Company granted its Chief Executive Officer options to purchase 50,000 shares of common stock. The options were priced at fair market value and vested 20% on the grant date, with an additional 20% vesting on the first four anniversaries of the grant date. The options expire ten years from the date of grant.

The assumptions made in estimating the fair value of the options on the grant date based upon the BSM option-pricing model for the six months ended June 30, 2016 are as follows:

Dividend yield	0.00%
Expected volatility	36.17%
Risk free interest rate	1.31%
Expected life	6 years

As of June 30, 2016, there was approximately $124 of unrecognized compensation expense. The Company expects to recognize this expense over the next four years.

This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including statements regarding our expectations, beliefs, intentions or strategies regarding the future. Forward-looking statements include, but are not limited to, statements relating to our marketing efforts or our efforts to accelerate growth; 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. We consider 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, as 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 in these forward-looking statements. The forward-looking statements we make in this Quarterly Report 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, 2015.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our consolidated 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, 2015. No new estimates exist other than those discussed in our Annual Report.

The following table contains selected financial information, for the periods indicated, from our consolidated statements of comprehensive income expressed as a percentage of net sales.

The following discusses the Company’s performance for the three and six months ended June 30, 2016 and 2015.

RESULTS OF OPERATIONS (in thousands)

Net Sales

Net sales for the three-month period ended June 30, 2016 decreased $39 or 1.9% over the same period in 2015. Net sales for the six-month period ended June 30, 2016 decreased $208 or 5.3% over the same period in 2015. The second quarter decrease primarily resulted from lower sales in the north central US and overseas territories, each area declining 26% over the corresponding 2015 three-month period. These decreases were partially offset by a 51% increase in large-order performance. In addition, plant upgrades and expansions in the animal feed industry resulted in the Company achieving strong results in our analog sensor product line.

Gross Profit

Gross profit for the three months ended June 30, 2016 increased $48, or 4.3%, over the same period in 2015. Gross profit for the six months ended June 30, 2016 decreased $80, or 3.7%, over the same period in 2015 due to lower revenue in the 2016 period. Gross margin, as a percentage of net sales, increased to 58.4% in the 2016 three-month period from 55.0% in the prior year, and increased to 56.6% in the 2016 six-month period compared to 55.6% in the prior year. Gross margin percentages were higher in the 2016 periods due to production efficiencies.

Operating Expenses

Total operating expenses decreased $32, or 3.2%, for the three months ended June 30, 2016 when compared to the same period in 2015 and decreased as a percentage of sales from 48.8% to 48.1%. Total operating expenses increased $21, or 1.0%, for the six months ended June 30, 2016 when compared to the same period in 2015 and increased as a percentage of sales from 51.5% to 55.0%.

· Selling and marketing expenses increased $37, or 9.0%, in the 2016 three-month period over the prior year, and increased as a percentage of net sales to 22.3% from 20.1%. Selling and marketing expenses increased $57, or 7.0%, in the 2016 six-month period over the prior year period, and increased as a percentage of net sales to 23.5% from 20.8%. The increase in expense dollars for the 2016 three-month period resulted from an increase in wages and benefits due to hiring of additional personnel. The increase for the 2016 six-month period resulted from an increase in wages and benefits due to additional personnel, the cost of providing system demonstrations to potential customers and increased travel. The six month increase is partially offset by a decrease in commission paid to outside manufacturers’ representatives due to lower sales volume.

· General and administrative expenses decreased $68, or 17.0%, for the 2016 three-month period compared to the same period in 2015 and decreased as a percentage of net sales to 16.5% from 19.5%. For the 2016 six-month period, general and administrative expenses increased $8, or 1.0%, compared to the 2015 period and increased as a percentage of net sales to 21.8% from 20.4%. The decrease for the 2016 three-month period was due to a decrease in the accrual for the contingent earn-out liability related to the HazardPRO acquisition and the expensing of post-closing deliverables related to the HazardPRO acquisition in 2015. The increase for the 2016 six-month period was due to an increase in wages and benefits and stock compensation expense due to an option granted to the Chief Executive Officer in February 2016. The six month increase was partially offset by a decrease in depreciation expense, the decrease in the contingent earn-out liability related to the HazardPRO acquisition and the 2015 expensing of post-closing deliverables related to the HazardPRO acquisition. During the second quarter of 2016, the Company decreased the contingent earn-out by $72 compared to a decrease of $17 in the same period for 2015.

· Research and development expenses decreased $1, or 0.1%, in the 2016 three–month period from the same period in 2015 but increased as a percentage of net sales to 9.3% from 9.2%. For the 2016 six–month period, research and development expenses decreased $44, or 10.9%, over the 2015 period, and decreased as a percentage of net sales to 9.7% from 10.3%. The percentage increase for the 2016 three-month period was due to lower sales in 2016 than in 2015. For the 2016 six-month period, the decrease was the result of lower wages and benefits due to reduced staffing levels in 2016 and costs incurred in 2015 related to lab testing fees for the HazardPRO product line. The decrease was partially offset by an increase in contract engineering related to the HazardPRO product line.

Operating Income

Three-month operating income grew 63.0% to $207 from $127 due to the 2016 higher gross margin and lower operating expenses while six-month operating revenue decreased 63.1% to $59 from $160, due primarily to lower fiscal 2016 first quarter revenue.

Non-Operating Income

Non-operating income decreased by $627, or 98.4%, for the 2016 three-month period compared to the same 2015 period. Non-operating income decreased $1,429, or 98.4%, in the six months ended June 30, 2016, when compared to the same period in 2015. This decrease was due to the liquidation of shares in Rudolph Technologies, Inc. in the second quarter of 2015. During the 2015 second quarter, we sold 49,066 shares of Rudolph Technologies, Inc. stock and recognized gain on the sales of $632. During the six-month period ended June 30, 2015, we sold 122,649 shares of Rudolph Technologies, Inc. stock and recognized gain on the sales of $1,447.

Income Before Income Taxes

Income before income taxes was $217 for the three months ended June 30, 2016, representing a decrease of $547, or 71.6%, when compared to the same period in 2015. Income before income taxes was $82 for the six months ended June 30, 2016, representing a decrease of $1,530, or 94.9%, when compared to the same period in 2015.

The decrease for both periods in 2016 was the result of a decrease in the sale of available-for-sale securities recognized in 2016. During the six-month period ended June 30, 2015, we recognized $1,449 of gain on sale of available-for-sale securities (see “Non-Operating Income (Expense)”).

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $560 at June 30, 2016, and $569 at December 31, 2015. The Company maintains a small cash balance and invests the majority of its available funds in United States Treasury securities.

Cash used in operations was favorably impacted by a decrease in inventories, and an increase in operating income, net of income taxes. For the 2016 six-month period we used $284 less cash in operations compared to the 2015 six-month period. In the 2016 period, the Company had a small decrease in inventories due to increased sales late in the 2016 second quarter. The increase in operating income, net of income taxes, is due to increased tax expense in 2015 due to the sales of available-for-sale securities.

Cash generated from investing activities was $401 and $1,854 for the six months ended June 30, 2016 and 2015, respectively. During the 2016 and 2015 six-month periods, the Company had net proceeds of Treasury Bills with a maturity date of more than three months of $403 and $402, respectively. In addition, the Company generated $1,467 in proceeds on the sale of available-for-sale securities during 2015 from the sale of Rudolph stock.

Cash used in financing activities was $390 and $381 for respective 2016 and 2015 six-month periods. During the six months ended June 30, 2016 and 2015, we paid $390 and $381, respectively, on the long-term debt owed to Harvest Engineering, Inc. (“Harvest”) for the technology purchased in February 2014. As of June 30, 2016, the note payable to Harvest has been paid in full.

Our ongoing cash requirements will be primarily for capital expenditures, research and development, and working capital. Management believes that cash on hand and any cash provided by operations will be sufficient to meet our cash requirements through at least the next 12 months.

Off-balance Sheet Arrangements

As of June 30, 2016, the Company had no off-balance sheet arrangements or transactions.

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.  Although the Company is continuing to explore these external opportunities, it currently has no agreements or understandings with any third parties.

Nature Of Business And Significant Accounting Policies [Abstract]

Basis Of Presentation

Note 1.  Basis of Presentation

The accompanying unaudited consolidated 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, 2015, including the audited consolidated 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, 2016 and for the three and six-month periods then ended 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 and make them easier to use, with the ultimate goal of manufacturing the industry-preferred product for every market served. The Company sells these productsthrough 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. 

Fair Value Measurements 

The carrying value of cash equivalents, treasury bills, trade receivables, accounts payable, and other financial working capital items approximates fair value at June  30, 2016 and December 31, 2015, due to the short maturity nature of these instruments.

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.

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 consolidated 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, contingent earn-out, and stock compensation expense.  It is at least reasonably possible that these estimates may change in the near term.

The fair value of the money market funds, commercial paper and treasury bills is based on quoted market prices in an active market. The available-for-sale security is a limited-marketable company.  There is an insignificant market for the limited-marketable company and the Company has determined its value based on financial and other factors, which are considered level 3 inputs in the fair value hierarchy.  Management estimated the probability of meeting the revenue targets over the measurement period to determine the fair value of the contingent earn-out, which is considered a level 3 input in the fair value hierarchy.

The change in level 3 liabilities at fair value on a recurring basis is summarized as follows:

	Period Ended June 30,
	2016			2015
Beginning Balance	$	455		$	472
Credit to earnings	(72		)	(17		)
Ending Balance	$	383		$	455

The decrease in the contingent liability reflects the Company’s expectation of moderately lower future contingent payments throughout the four year earn-out period.

Stock-Based Compensation

Note 5.  Stock-Based Compensation 

During the first quarter of 2016, the Company granted its Chief Executive Officer options to purchase 50,000 shares of common stock.  The options were priced at fair market value and vested 20% on the grant date, with an additional 20% vesting on the first four anniversaries of the grant date.  The options expire ten years from the date of grant. 

The assumptions made in estimating the fair value of the options on the grant date based upon the BSM option-pricing model for the six months ended June 30, 2016 are as follows:

Dividend yield	0.00%
Expected volatility	36.17%
Risk free interest rate	1.31%
Expected life	6 years

As of June 30, 2016, there was approximately $124 of unrecognized compensation expense.  The Company expects to recognize this expense over the next four years.

Segment Information

Note 6.  Segment Information 

As of January 1, 2016, the Company has one reportable operating segment: Production Monitoring.  During 2015, the Company had two reportable operating segments: Production Monitoring and Investments.  The Production Monitoring Division manufactures and markets a complete line of production monitoring equipment.  ESI Investment Company held investments in marketable and non-marketable securities.

Fair Value Measurements

Fair Value Measurements 

The carrying value of cash equivalents, treasury bills, trade receivables, accounts payable, and other financial working capital items approximates fair value at June  30, 2016 and December 31, 2015, due to the short maturity nature of these instruments.

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.

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 consolidated 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, contingent earn-out, and stock compensation expense.  It is at least reasonably possible that these estimates may change in the near term.
