UNITED STATES LIME & MINERALS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.    Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by United States Lime & Minerals, Inc. (the “Company”) without independent audit.  In the opinion of the Company’s management, all adjustments of a normal and recurring nature necessary to present fairly the financial position, results of operations, comprehensive income and cash flows for the periods presented have been made.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) have been condensed or omitted.  These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2016.  The results of operations for the three- and nine-month periods ended September 30, 2017 are not necessarily indicative of operating results for the full year.

2.    Organization

The Company is headquartered in Dallas, Texas, and operates through two business segments.  Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), industrial (including paper and glass manufacturers), metals (including steel producers), roof shingle, oil and gas services and agriculture (including poultry and cattle feed producers) industries.  The Company operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company – Shreveport, U.S. Lime Company – St. Clair and U.S. Lime Company – Transportation.

The Company’s Natural Gas Interests segment is held in its wholly owned subsidiary, U.S. Lime Company – O & G, LLC (“U.S. Lime O & G”).  Under a lease agreement (the “O & G Lease”), U.S. Lime O & G has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest, resulting in an overall average revenue interest of 34.7%, with respect to oil and gas rights in 33 wells drilled and currently producing on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. Through U. S. Lime O & G, the Company also has a drillsite and production facility lease agreement and subsurface easement (the “Drillsite Agreement”) relating to approximately 538 acres of land contiguous to the Company’s Johnson County, Texas property.  Pursuant to the Drillsite Agreement, the Company receives a 3% royalty interest and a 12.5% non-operating working interest, resulting in a 12.4% revenue interest, in the six wells drilled and currently producing from pad sites located on the Company’s property.

3.    Accounting Policies

Revenue Recognition.  The Company recognizes revenue for its Lime and Limestone Operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues.  The Company’s returns and allowances are minimal.  External freight billed to customers included in 2017 and 2016 revenues was $5.8 million and $6.7 million for the three-month periods, and $17.8 million and $17.6 million for the nine-month periods, respectively, which approximates the amount of external freight included in cost of revenues. Sales taxes billed to customers are not included in revenues.  For its Natural Gas Interests, the Company recognizes revenue in the month of production and delivery.

Successful-Efforts Method Used for Natural Gas Interests.  The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures.  Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method.  Costs to drill exploratory wells that do not find proved reserves are expensed.

6

Comprehensive Income.  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  Certain changes in assets and liabilities, such as mark-to-market gains or losses on interest rate and foreign exchange derivative instruments designated as hedges, are reported as a separate component of the equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income.

Fair Values of Financial Instruments.  Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”  The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities.  These tiers include:  Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.  Specific inputs used to value the Company’s foreign exchange hedges were Euro to U.S. Dollar exchange rates for the expected future payment dates for the Company’s commitments denominated in Euros. See Note 6.  There were no changes in the methods and assumptions used in measuring fair value. 

The Company’s financial assets and liabilities measured at fair value on a recurring basis at September 30, 2017 and December 31, 2016, respectively, are summarized below (in thousands):

					Significant Other

New Accounting Pronouncements.  In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers,” which stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  To achieve this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract(s); (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract(s); and (5) recognize revenue when (or as) the entity satisfies a performance obligation.  The new guidance will be effective for the Company beginning January 1, 2018, with early adoption permitted for annual periods beginning after December 15, 2016.  Almost all of the Company’s purchase orders, contracts or purchase agreements do not contain performance obligations other than delivery of the agreed upon product, which is primarily FOB shipping point.  Thus, the Company generally recognizes revenue upon shipment of the product.  While the Company is still in the process of completing an analysis of all of its revenue generating activities and the contracts which might impact its revenue generating activities in light of the new standard, the Company does not believe that any of its revenue streams will be materially affected by the adoption of ASU 2014-09, and therefore it does not expect its Consolidated Statements of Operations will be materially affected.  The Company plans to adopt ASU 2014-09 beginning January 1, 2018 using the modified retrospective approach and recognize a cumulative effect of the change, if any, to opening retained earnings in the year of adoption.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous guidance.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and interim periods within those periods, with early adoption permitted.  ASU 2016-02 must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented.  As of December 31, 2016, the Company’s undiscounted minimum contractual commitments under long-term leases, which were not recorded on the Company’s December 31, 2016 Consolidated Balance Sheet, was $6.8 million, which is an estimate of the effect on total assets and total liabilities that the new

7

accounting standard could have on that date.  The Company is currently evaluating the effect that this standard will have on the Company’s Consolidated Financial Statements.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), “Compensation – Stock Compensation,” which requires that excess tax benefits (which represent the excess of actual tax benefits received at the date of vesting or settlement over the vesting period or upon issuance of share-based payments) and tax deficiencies (which represents the amount by which actual tax benefits received at the date of vesting or settlement is lower than the benefits recognized over the vesting period or upon issuance of share-based payments) be recorded in the income statement as a reduction or increase of income taxes when an award vests.  It also requires excess tax benefits to be classified as an operating activity in the statement of cash flows rather than a financing activity.  In addition, it simplifies other aspects of share-based payment transactions, including classification of awards that permit repurchase to satisfy statutory tax withholding requirements and classification of tax payments on behalf of employees on the statement of cash flows.  The Company adopted this guidance in the first quarter 2017, and it did not have a material effect on the Company’s Condensed Consolidated Financial Statements. 

In August 2017, the FASB issued Accounting Standards Update No. 2017-12 (“ASU 2017-12”), “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.”  This standard better aligns an entity’s risk management activities and financial reporting for hedging relationships and enhances the transparency and understandability of hedge results through improved disclosures.  ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years.  The Company is currently assessing the effect that this standard will have on the Company’s Consolidated Financial Statements.

4.   Business Segments

The Company has identified two business segments based on the distinctness of their activities and products:  Lime and Limestone Operations and Natural Gas Interests.  All operations are in the United States.  In evaluating the operating results of the Company’s segments, management primarily reviews revenues and gross profit.  The Company does not allocate corporate overhead or interest costs to its business segments.

The following table sets forth operating results and certain other financial data for the Company’s two business segments (in thousands):

(1) Excludes 7.5 stock options for the 2016 periods as anti-dilutive because the exercise price exceeded the average per share market price for the period.

6.    Accumulated Other Comprehensive Income (Loss)

The following table presents the components of comprehensive income (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Net income	$	5,667	$	6,081	$	15,565	$	13,834
Mark to market of foreign exchange hedges		92		—		532		—
Deferred income tax expense		(34)		—		(195)		—
Comprehensive income	$	5,725	$	6,081	$	15,902	$	13,834

In November 2016, to hedge against potential losses due to changes in the Euro to U.S. Dollar exchange rates, the Company entered into foreign exchange (“FX”) hedges with Wells Fargo Bank, N.A. as the counterparty to the FX hedges to fix the exchange rate for 5.5 million Euros in connection with a contractual obligation related to the St. Clair kiln project.  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the FX hedges.  The FX hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the FX hedges are reflected in comprehensive income.  Due to the weakening of the U.S. Dollar, compared to the Euro, in the 2017 periods, the change in the fair value of the remaining 3.7 million Euro FX hedges resulted in an asset of $181 thousand at September 30, 2017, which is included in prepaid expenses and other current assets ($142 thousand) and other assets, net ($39 thousand) at September 30, 2017.  Due to the strengthening of the U.S. Dollar, compared to the Euro, in the period from when the Company entered into the FX hedges through December 31, 2016, the fair value of the FX hedges resulted in a liability of $352 thousand at December 31, 2016, which is included in accrued expenses ($309 thousand) and other liabilities ($43 thousand) at December 31, 2016.

7.    Inventories, Net

Inventories are valued principally at the lower of cost, determined using the average cost method, or market.  Costs for raw materials and finished goods include materials, labor, and production overhead.  Inventories, net consisted of the following (in thousands):

	September 30,		December 31,
	2017		2016
Lime and limestone inventories:
Raw materials	$	4,502	$	4,811

	$	6,354	$	6,881
Service parts inventories		6,177		5,552
	$	12,531	$	12,433

8.   Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”) provides for a $75 million revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion feature to borrow up to an additional $50 million on the same terms, subject to approval by the Lender or another lender selected by the Company.  The Revolving Facility and any incremental loan mature on May 7, 2020.  Interest rates are, at the Company’s option, LIBOR plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate plus a margin of 0.000% to 1.000%; and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving Facility.  The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.  Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property.  The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs.  The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.  As of October 27, 2016, the Company amended its credit agreement to increase the letter of credit sublimit under the Revolving Facility from $5 million to $10 million. 

The Company may pay dividends so long as it remains in compliance with the provisions of the Company’s credit agreement, and may purchase, redeem or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

As of September 30, 2017, the Company had  no debt outstanding and no draws on the Revolving Facility other than $7.0 million of letters of credit, including $6.5 million related to the St. Clair kiln project, which count as draws against the available commitment under the Revolving Facility.

9.    Income Taxes

The Company has estimated that its effective income tax rate for 2017 will be 20.3%.  The primary reasons for the effective rate being below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income, and income tax credits associated with the ongoing construction of the St. Clair kiln project.

10.    Dividends

On September 15, 2017, the Company paid $0.8 million in cash dividends, based on a dividend of $0.135 (13.5 cents) per share on its common stock, to shareholders of record at the close of business on August 25, 2017.  On June 16, 2017, the Company paid $0.8 million in cash dividends, based on a dividend of $0.135 (13.5 cents) per share on its

10

common stock, to shareholders of record at the close of business on May 26, 2017.  On March 17, 2017, the Company paid $0.8 million in cash dividends, based on a dividend of $0.135 (13.5 cents) per share on its common stock, to shareholders of record at the close of business on February 24, 2017.

11.    Subsequent Event

On October 26, 2017, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.135 (13.5 cents) per share on the Company’s common stock.  This dividend is payable on December 15, 2017 to shareholders of record at the close of business on November 24, 2017.

Overview.

The Company has two operating segments:  Lime and Limestone Operations and Natural Gas Interests.  Revenues and gross profit are the primary items utilized to evaluate the operating results of the Company’s segments and to allocate resources.

Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), industrial (including paper and glass manufacturers), metals (including steel producers), roof shingle, oil and gas services and agriculture (including poultry

12

and cattle feed producers) industries.  The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company – Shreveport, U.S. Lime Company – St. Clair and U.S. Lime Company – Transportation.  The Lime and Limestone Operations represent the Company’s principal business.

The Company’s Natural Gas Interests are held in its wholly owned subsidiary, U.S. Lime Company – O & G, LLC, and consist of royalty and non-operating working interests under the O & G Lease with EOG Resources, Inc. (“EOG”) and the Drillsite Agreement with XTO Energy, Inc. related to the Company’s Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime Company conducts its lime and limestone operations.  Affilliated companies of Enervest, Ltd. have purchased EOG’s interests in the O & G Lease, and an affiliate of Enervest, Ltd. is now the successor operator of the wells drilled under the O & G Lease.  No new wells have been drilled or completed on the O&G Properties since 2011.  The Company cannot predict if any additional wells will be drilled on the O & G Properties, or their results.

Revenues from the Company’s Lime and Limestone Operations decreased 4.4% in the third quarter 2017, compared to the third quarter 2016, and increased 4.1% in the first nine months 2017, compared to the first nine months 2016.  The decrease in revenues in the third quarter 2017 resulted from decreased sales volumes of 4.4% for the Company’s lime and limestone products, principally from its environmental and construction customers, offset in part by increased demand from its oil and gas services customers.  The Company’s facilities in the affected region suffered only minor damages due to Hurricane Harvey, but demand from certain of its construction customers during the third quarter was adversely impacted by the storm. 

The increase in the Company’s lime and limestone revenues in the first nine months 2017 resulted primarly from increased sales volumes of 3.1%, due to increased demand from its oil and gas services and construction customers, partially offset by reduced demand from its environmental customers.  Prices realized for the Company’s lime and limestone products were flat in the third quarter 2017, compared to the third quarter 2016, and 0.2% higher in the first nine months 2017, compared to the comparable 2016 period. 

The Company’s gross profit from its Lime and Limestone Operations decreased by 9.8% in the third quarter 2017 and increased by 2.1% in the first nine months 2017, compared to the comparable 2016 periods.  The decreased gross profit for the Company’s Lime and Limestone Operations in the third quarter 2017, compared to the third quarter 2016, resulted primarily from the decreased revenues in the third quarter 2017 discussed above.  The increased gross profit in the first nine months 2017, compared to the comparable 2016 period, resulted primarily from the increased revenues in the first nine months 2017 discussed above.

Revenues from the Company’s Natural Gas Interests decreased 8.7% in the third quarter 2017, compared to the third quarter 2016.  The decrease in revenues from Natural Gas Interests in the third quarter 2017 resulted primarily from a 12.5% decrease in production volumes due to the normal declines in production rates on the Company’s 39 existing wells, partially offset by 3.8%  higher natural gas and natural gas liquids prices. Revenues from the Company’s Natural Gas Interests increased 13.8% in the first nine months 2017, compared to the comparable 2016 period, primarily from 26.6% higher natural gas and natural gas liquids prices, partially offset by a 12.8% decrease in production volumes due to the normal declines in production rates on the Company’s 39 existing wells.  The Company’s gross profit from its Natural Gas Interests was flat at $0.1 million in each of the third quarters 2017 and 2016 and increased to $0.4 million in the first nine months 2017, compared to a loss of $19 thousand in the comparable 2016 period, which resulted primarily from the increase in revenues in the first nine months 2017 discussed above.

In the fourth quarter 2016, the Company began a modernization and expansion and development project at its St. Clair plant in Oklahoma, including construction of a new, more fuel-efficient vertical kiln and related plant improvements.  Work on the St. Clair kiln project is moving forward.  Through September 30, 2017, the Company had incurred approximately $10.3 million of costs on the St. Clair kiln project, and had remaining outstanding commitments of approximately $20.0 million related to the project as of such date.  The Company estimates that the St. Clair kiln project will cost approximately $50 million and be completed by the end of 2018.

13

In December 2015, the Company commenced a publicly announced share repurchase program to purchase up to $10 million of its common stock.  In November 2016, the Company announced a 12-month extension of the repurchase program to repurchase up to the $7.2 million of its common stock remaining under the program.  No shares have been repurchased under the program since the first quarter 2016, when the Company repurchased 50,068 shares at a weighted-average price of $53.52 per share. Since the commencement of the share repurchase program through the date of this Report, the Company has repurchased 53,154 shares at a weighted-average price of $53.59 per share.

The Company paid its regular quarterly cash dividend of $0.135 (13.5 cents) per share on its common stock in each of the first three quarters 2017.  On October 26, 2017, the Company’s Board of Directors declared a regular quarterly cash dividend of $0.135 (13.5 cents) per share on the Company’s common stock.  This dividend is payable on Decembr 15, 2017 to shareholders of record at the close of business on November 24, 2017.

Liquidity and Capital Resources.

Net cash provided by operating activities was $24.0 million in the first nine months 2017, compared to $25.9 million in the comparable 2016 period, a decrease of $1.9 million, or 7.4%.  Net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”), deferred income taxes and other non-cash items included in net income, and changes in working capital.  In the first nine months 2017, cash provided by operating activities was principally composed of $15.6 million net income and $12.7 million DD&A, partially offset by a $1.2 million decrease in deferred income taxes, compared to $13.8 million net income and $12.0 million DD&A in the first nine months 2016.  The most significant changes in working capital items in the first nine months 2017 were an increase in trade receivables, net of $1.5 million, an increase in inventories, net, of $0.4 million, an increase in prepaid expenses and other current assets of $0.3 million and a decrease in accounts payable and accrued expenses of $2.0 million.  The most significant changes in working capital items in the first nine months 2016 were an increase in trade receivables, net, of $3.5 million, a decrease in inventories of $2.0 million and a decrease in prepaid expenses and other current assets of $0.7 million.  The increase in trade receivables, net in the 2017 and 2016 first nine-month periods primarily resulted from increased revenues in the third quarter 2017, compared to the fourth quarter 2016, and increased revenues in the third quarter 2016, compared to the fourth quarter 2015, respectively.

The Company had $14.5 million in capital expenditures in the first nine months 2017, including approximately $6.4 million on the St. Clair kiln project, compared to $12.2 million in the comparable period last year. 

Net cash used in financing activities was $2.4 million and $4.8 million in the 2017 and 2016 first nine months, respectively, consisting of purchase of treasury shares of $0.2 million and $2.8 million in the first nine months 2017 and 2016, respectively.  Additionally, the Company paid $2.3 million and $2.1 million in dividends during the first nine months 2017 and 2016, respectively. 

Cash and cash equivalents increased $7.5 million to $82.2 million at September 30, 2017, from $74.7 million at December 31, 2016. 

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”) provides for a $75 million revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion feature to borrow up to an additional $50 million on the same terms, subject to approval by the Lender or another lender selected by the Company.  The Revolving Facility and any incremental loan mature on May 7, 2020.  Interest rates are, at the Company’s option, LIBOR plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate plus a margin of 0.000% to 1.000%; and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving Facility.  The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.  Pursuant to a security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property.  The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs.  The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.  As of October 27, 2016, the

14

Company amended its credit agreement to increase the letter of credit sublimit under the Revolving Facility from $5 million to $10 million. 

The Company may pay dividends so long as it remains in compliance with the provisions of the Company’s credit agreement, and may purchase, redeem or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

The Company is not contractually committed to any planned capital expenditures until actual orders are placed for equipment.  As of September 30, 2017, the Company had no material open orders or commitments that are not included in current liabilities on the September 30, 2017 Condensed Consolidated Balance Sheet other than approximately $20.0 million related to the St. Clair kiln project. 

In November 2016, to hedge against potential losses due to changes in the Euro to U.S. Dollar exchange rates, the Company entered into foreign exchange (“FX”) hedges with Wells Fargo Bank, N.A. as the counterparty to the FX hedges to fix the exchange rate for 5.5 million Euros in connection with a contractual obligation related to the St. Clair kiln project.  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the FX hedges.  The FX hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the FX hedges are reflected in comprehensive income.  Due to the weakening of the U.S. Dollar, compared to the Euro, in the 2017 periods, the fair value of the FX hedges resulted in an asset of $181 thousand at September 30, 2017, which is included in prepaid expenses and other current assets ($141 thousand) and other assets, net ($40 thousand) at September 30, 2017.  Due to the strengthening of the U.S. Dollar, compared to the Euro, in the period from when the Company entered into the FX hedges through December 31, 2016, the fair value of the FX hedges resulted in a liability of $352 thousand at December 31, 2016, which is included in accrued expenses ($309 thousand) and other liabilities ($43 thousand) at December 31, 2016.

As of September 30, 2017, the Company had no debt outstanding and no draws on the Revolving Facility other than $7.0 million of letters of credit, including $6.5 million related to the St. Clair kiln project, which count as draws against the available commitment under the Revolving Facility.  The Company believes that, absent a significant acquisition, cash on hand and cash flows from operations will be sufficient to meet the Company’s operating needs, ongoing capital needs, including current and possible modernization and expansion and development projects, including the kiln project at St. Clair, and liquidity needs and allow it to continue to repurchase up to $7.2 million of its common stock remaining to be repurchased under its extended share repurchase program as well as pay its regular cash dividends for the near future.

Results of Operations.

Revenues in the third quarter 2017 were $36.9 million, compared to $38.7 million in the comparable prior year quarter, a decrease of $1.7 million, or 4.4%.  Revenues from the Company’s Lime and Limestone Operations in the third quarter 2017 decreased $1.7 million, or 4.4%, to $36.4 million from $38.1 million in the comparable 2016 quarter, while revenues from its Natural Gas Interests decreased $48 thousand, or 8.7%, to $506 thousand from $554 thousand in the comparable prior year quarter.  In the first nine months 2017, revenues were $109.6 million, compared to $105.1 million in the comparable 2016 period, an increase of $4.5 million, or 4.3%.  Revenues from the Company’s Lime and Limestone Operations in the first nine months 2017 increased $4.3 million, or 4.1%, to $107.9 million from $103.6 million in the comparable 2016 period, while revenues from its Natural Gas Interests increased $0.2 million, or 13.8%, to $1.7 million from $1.5 million in the comparable prior year period.

As discussed above, the decrease in lime and limestone revenues in the third quarter 2017, as compared to the third quarter 2016, resulted from decreased sales volumes of the Company’s lime and limestone products, while the increase in the Company’s lime and limestone revenues in the first nine months 2017, as compared to last year’s comparable period, resulted primarily from increased sales volumes.  Prices realized for the Company’s lime and limestone products were flat in the third quarter, compared to the third quarter 2016, and slightly higher in the first nine months 2017, compared to the comparable 2016 period.

15

Production volumes from the Company’s Natural Gas Interests in the third quarter 2017 totaled 137 thousand MCF, sold at an average price of $3.69 per MCF, compared to 156 thousand MCF, sold at an average price of $3.56 per MCF, in the comparable 2016 quarter.  Production volumes in the first nine months 2017 from Natural Gas Interests totaled 425 thousand MCF, sold at an average price of $3.98 per MCF, compared to the first mime months 2016 when 473 thousand MCF was produced and sold at an average price of $3.15 per MCF.  The Company’s 2017 average prices per MCF were higher than the prior year’s average prices primarily due to increases in market prices for natural gas and natural gas liquids.

The Company’s gross profit was $9.6 million in the third quarter 2017, compared to $10.6 million in the comparable 2016 quarter, a decrease of $1.0 million, or 9.6%. Gross profit in the first nine months 2017 was $26.6 million, an increase of $1.0 million, or 3.8%, from $25.7 million in the first nine months 2016.

Included in gross profit in the third quarter and first nine months 2017 were $9.5 million and $26.2 million, respectively, from the Company’s Lime and Limestone Operations, compared to $10.5 million and $25.7 million, respectively, in the comparable 2016 periods.  The decreased gross profit for the Company’s lime and limestone operations in the third quarter 2017, compared to the third quarter 2016, resulted primarily from the decreased revenues discussed above.  The increased gross profit in the first nine months 2017, compared to the comparable 2016 period, resulted primarily from the increased revenues discussed above.  The Company’s gross profit margin as a percent of revenues from its Lime and Limestone Operations decreased to 26.0% and 24.3% in the third quarter and first nine months 2017, respectively, from 27.6% and 24.8% in the third quarter and first nine months 2016, respectively.  The decreased gross profit and gross profit margin in the third quarter 2017 resulted primarily from the decrease in revenues discussed above.

Gross profit from the Company’s Natural Gas Interests was flat at $0.1 million in each of the third quarters 2017 and 2016.  For the first nine months 2017, gross profit from the Company’s Natural Gas Interest increased to $0.4 million from a loss of $19 thousand in the comparable 2016 period, which resulted primarily from the increase in revenues in the first nine months 2017 discussed above.

Selling, general and administrative expenses (“SG&A”) were $2.7 million and $7.6 million in the third quarter and first nine months 2017, respectively, compared to $2.5 million and $7.2 million in the third quarter and first nine months 2016, respectively.  As a percentage of revenues, SG&A was 7.2% and 6.9% in the third quarter and first nine months 2017, respectively, compared to 6.4% and 6.9%, in the third quarter and first nine months 2016, respectively.  The increase in SG&A as a percentage of revenues in the third quarter 2017 compared to the third quarter 2016 was primarily due to the decrease in revenues in the 2017 period, compared to the comparable 2016 period.  The increase in SG&A in the 2017 periods, compared to the comparable 2016 periods, was principally due to increased non-cash stock-based compensation costs, which is primarily due to the increases in the price per share of the Company’s common stock for grants expensed during the 2017 periods, compared to the comparable 2016 periods.

Interest expense was $0.1 million in each of the 2017 and 2016 third quarters, and $0.2 million in each of the 2017 and 2016 first nine months. Other income, net was $0.3 million in the third quarter 2017, compared to $0.1 million in the third quarter 2016, and $0.7 million in the first nine months 2017, compared to $0.2 million in the first nine months 2016, primarily due to increased interest earned on the Company’s cash balances. 

Income tax expense decreased to $1.4 million in the third quarter 2017, compared to $2.1 million in the third quarter 2016, a decrease of $0.6 million or 30.4%.   In the first nine months 2017, income tax expense decreased to $4.0 million from $4.7 million in the comparable 2016 period, a decrease of $0.7 million, or 15.1%.  The decrease in income tax expense in the third quarter and the first nine months 2017, compared to the comparable 2016 periods, was primarily due to a decrease in the Company’s estimated effective income tax rate resulting from income tax credits associated with the ongoing St. Clair kiln project, partially offset for the first nine months 2017 by the increase in the Company’s income before income taxes.

The Company’s net income was $5.7 million ($1.01 per share diluted) in the third quarter 2017, compared to net income of $6.1 million ($1.09 per share diluted) in the third quarter 2016, a decrease of $0.4 million, or 6.8%.  Net

16

income in the first nine months 2017 was $15.6 million ($2.79 per share diluted), an increase of $1.7 million, or 12.5%, compared to the first nine months 2016 net income of $13.8 million ($2.48 per share diluted).

ITEM 3:     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

The Company would be exposed to changes in interest rates, primarily as a result of floating interest rates on the Revolving Facility.  There was no outstanding balance on the Revolving Facility subject to interest rate risk at September 30, 2017.  Any future borrowings under the Revolving Facility would be subject to interest rate risk.  See Note 8 of Notes to Condensed Consolidated Financial Statements.

Foreign Exchange Risk.

The Company could be exposed to changes in the Euro to U.S. Dollar exchange rate for its 3.7 million Euros obligation related to a contract for the St. Clair kiln project.  The Company entered into FX hedges to fix its U.S. Dollar liability at $4.2 million.  See Note 6 of Notes to Condensed Consolidated Financial Statements.

ITEM 4:     CONTROLS AND PROCEDURES

The Company’s management, with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this Report.  Based upon that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures as of the end of the period covered by this Report were effective.

No change in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II.     OTHER INFORMATION

ITEM 2:     UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In December 2015, the Company commenced a publicly announced share repurchase program to repurchase up to $10 million of its common stock.  In November 2016, the Company announced a 12-month extension of the repurchase program to repurchase up to the $7.2 million of its commons stock remaining under the program.  The Company did not repurchase any shares pursuant to this program the the third quarter 2017.

ITEM 4:    MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S‑K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC.  The operation of the Company’s quarries, underground mine and plants is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977.  The required information regarding certain mining safety and health matters, broken down by mining complex, for the quarter ended September 30, 2017 is presented in Exhibit 95.1 to this Report.

The Company believes it is responsible to employees to provide a safe and healthy workplace environment. The Company seeks to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety standards and establishing and improving safe work practices; involving employees in safety processes; and recording, reporting and investigating accidents, incidents and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar penalties assessed for citations and orders issued in recent years.
