In the opinion of management, these statements reflect all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the financial position of IKONICS Corporation as of June 30, 2016, and the results of operations and cash flows for all periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. Therefore, these statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The results of operations for interim periods are not necessarily indicative of results that will be realized for the full fiscal year. For comparability, certain 2015 amounts related to deferred tax assets and liabilities have been reclassified to conform with classifications adopted in 2016. The reclassifications had no impact on net loss or stockholders’ equity.

Earnings Per Common Share (EPS)
Earnings Per Common Share (EPS)	4. Earnings Per Common Share (EPS) Basic EPS is calculated using net income (loss) divided by the weighted average of common shares outstanding. Diluted EPS is similar to Basic EPS except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if the potential dilutive common shares, such as those shares subject to options, had been issued. Shares used in the calculation of diluted EPS are summarized below: Three Months Ended Jun 30, 2016 Jun 30, 2015 Weighted average common shares outstanding Dilutive effect of stock options Weighted average common and common equivalent shares outstanding Six Months Ended Jun 30, 2016 Jun 30, 2015 Weighted average common shares outstanding Dilutive effect of stock options — — Weighted average common and common equivalent shares outstanding For the three months ended June 30, 2016, options to purchase 11,418 shares of common stock with a weighted average price of $15.99 were outstanding but were excluded from the computation of common share equivalents because they were anti-dilutive. For the three months ended June 30, 2015, options to purchase 6,250 shares of common stock with a weighted average price of $18.28 were outstanding but were excluded from the computation of common share equivalents because they were anti-dilutive. If the Company was in a net income position for the first six months of 2016, 4,750 options with a weighted average exercise price of $10.59 would have been included as part of the weighted average common and common equivalent shares outstanding as the options would have been dilutive, while 11, 418 options with a weighted average exercise price of $15.99 would have remained excluded as the options were anti-dilutive. If the Company was in a net income position for the first six months of 2015, 5,918 options with a weighted average exercise price of $12.49 would have been included as part of the weighted average common and common equivalent shares outstanding as the options would have been dilutive while 6,250 options with a weighted average exercise price of $18.28 would have remained excluded as the options were anti-dilutive .

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Stock-Based Compensation
Stock-Based Compensation	5. Stock-Based Compensation The Company maintains a stock incentive plan which authorizes the issuance of up to 442,750 shares of common stock. Of those shares, 16,168 were subject to outstanding options and 104,239 were reserved for future grants at June 30, 2016. The plan provides for granting eligible participants stock options or other stock awards, as described by the plan, at option prices ranging from 85% to 110% of fair market value at the date of grant. Options granted expire up to seven years after the date of grant. Such options generally become exercisable over a one - to three - year period. The Company charged compensation cost of approximately $6,500 against income for the three months ended June 30, 2016 and approximately $5,700 for the three months ended June 30, 2015. For the first six months of 2016, the Company charged compensation cost of approximately $11,800 and approximately $10,400 for the same period in 2015. As of June 30, 2016, there was approximately $46,000 of unrecognized compensation cost related to unvested share-based compensation awards. That cost is expected to be recognized over the next three years. The Company receives a tax deduction for certain stock option exercises during the period in which the options are exercised, generally for the excess of the market price at the time the stock options are exercised over the exercise price of the options, which increases additional paid in capital and reduces income taxes payable. Proceeds from the exercise of 5 00 stock options were approximately $4,000 for the six months ended June 30, 2016. No stock options were exercised during the six months ended June 30, 2015. The fair value of options granted during the six months ended June 30, 2016 and 2015 was estimated using the Black-Scholes option pricing model with the following assumptions: 2016 2015 Dividend yield 0% 0% Expected volatility 42.4% 42.3% - 42.4% Expected life of option Five Years Five Years Risk-free interest rate 1.3% 1.4% - 1.5% Fair value of each option on grant date $ 4.02 $5.43 - $6.14 There wer e 4,500 and 7,250 opti ons granted during each of the six months ended June 30, 2016 and 2015, respectively. Stock option activity during the six months ended June 30, 2016 was as follows: Weighted Average Exercise Shares Price Outstanding at January 1, 2016 $ Granted Exercised Outstanding at June 30, 2016 $ Exercisable at June 30, 2016 $ The aggregate intrinsic value of all options outstanding and for those exercisable at June 30, 2016 was approximately $3,000 and $1,000 , respectively.

LONG-TERM DEBT
LONG-TERM DEBT	6. Long-Term Debt On April 1, 2016, the Company entered into a financing agreement (the “Financing Agreement”) under which the Duluth Economic Development Authority (the “Issuer”) agreed to sell $3,415,000 of its Tax Exempt Industrial Revenue Bonds, Series 2016 (IKONICS Project) (the “Bonds”) to Wells Fargo Bank, National Association (the “Bank”), and the Bank agreed to lend to the Company the proceeds received from the sale of the Bonds (the “Loan”). The closing of the sale of the Bonds occurred on April 29, 2016. The proceeds from the Loan were used to finance the construction of a 27,300 -square foot building as well as related equipment for use in the Company’s manufacture of sound deadening technology used in the aerospace industry and products consisting of etched composites, ceramics, glass and silicon wafers, to be located in Duluth, Minnesota (the “Project”). The Loan requires monthly payments of approximately $18,000 , including interest. The Loan bears interest at a rate of 2.14% per year, payable monthly, and matures on April 1, 2041. Including debt costs of approximately $139,000 , the Loan’s effective interest rate is 2.77% per year. The Loan is subject to mandatory purchase provisions, under which any owners of the Bonds (the “Owners”) must tender the Bonds to the Issuer on April 1, 2021 and the Issuer, using solely funds furnished by the Company for such purpose, will purchase the Bonds at a purchase price of 100% of the principal amount of the outstanding Bonds, plus accrued and unpaid interest thereon. In the event the Bonds are not repurchased on April 1, 2021, the Bonds shall be subject to the interest rate and redemption provisions set forth in the associated covenant agreement. Subject to limitations in the associated covenant agreement, the Company may cause a redemption of the Bonds, in whole or in part, in authorized denominations at the redemption prices set forth in the Financing Agreement, together with any accrued or unpaid interest to the date of redemption. The Bonds are also subject to redemption in whole in the event of certain extraordinary events related to the Project. The Company is subject to certain customary covenants set forth in the associated covenant agreement, including a requirement that the Company maintain a debt service coverage ratio as of the end of each calendar quarter of not less than 1.25 to 1.00 on a rolling four-quarter basis. At June 30, 2016 the Company was in compliance with all financial and non-financial covenants under the Financing Agreement. The remaining principal payments required under the agreement for years ended December 31, and the current and long ‑term portion of the principal, are as follows: 2016 $ 2017 2018 2019 2020 Thereafter Total Principal Less: Current portion Long-term portion $ In connection with the agreement, the Company incurred debt issuance costs of approximately $139,000 during the six months ended June 30, 2016, which were deferred and are being amortized over the term of the Financing Agreement. Amortization of debt issuance costs was approximately $2,000 for the six months ended June 30, 2016 and is included in interest expense. Debt issuance costs of $124,000 and $13,000 are netted against long-term debt and current portion of long ‑term debt, respectively as of June 30, 2016. Amortization of debt costs is expected to be approximately $9,000 in 2016 and approximately $12,000 annually for each of the next four years. In addition to the $3,415,000 in indebtedness pursuant to the Loan, the Company has a bank line of credit providing for borrowings of up to $2,050,000 , expiring on May 31, 2017 that bears interest at 1.8 percentage points over the 30 ‑day LIBOR rate. The Company did not utilize this line of credit during the first six months of 2016 or 2015 and there were no borrowings outstanding as of June 30, 2016 and December 31, 2015. There are no financial covenants related to the line of credit. Both the $3,415,000 financing pursuant to the Loan and the line of credit are collateralized by substantially all assets of the Company.
