NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(1) CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited consolidated financial statements have been prepared by management in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for the fair presentation of results for the interim period have been included. The Company's operations are seasonal; for this and other reasons, financial results for any interim period are not necessarily indicative of the results expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual Form 10-K for the year ended December 31, 2018.

The balance sheet at December 31, 2018 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

(2) RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-02 Leases (Topic 842)	The standard requires lessees to recognize most leases as assets and liabilities on the balance sheet, but record expenses on the statement of operations in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The standard also requires additional disclosures about leasing arrangements and requires a modified retrospective transition approach for existing leases, whereby the standard will be applied to the earliest year presented. The provisions of the standard are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.	The Company has adopted this standard using the modified retrospective approach and elected the transition method to initially apply the new leases standard to all leases that exist at January 1, 2019. Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019. The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period. The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows. Date of adoption: Q1 2019

Recent Accounting Pronouncements Not Yet Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-13 Financial Instruments - Credit Losses (Topic 326)	The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The provisions of this standard are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.	The Company is currently evaluating the requirements of this standard. The standard is not expected to have a material impact on the Company's financial statements. Date of adoption: Q1 2020

(6)    ACQUISITIONS

On August 21, 2018, the Company acquired all of the outstanding stock of SolarBOS. SolarBOS is a provider of electrical balance of systems products, which consists of electrical components such as wiring, switches, and combiner boxes that support photovoltaic systems, for the U.S. solar renewable energy market. The Company expects the acquisition of SolarBOS to enable the Company to provide complementary product offerings to its existing customers and strengthen its position in the solar renewable energy market. The results of SolarBOS have been included in the Company's consolidated financial results since the date of acquisition (within the Company's Renewable Energy and Conservation segment). The aggregate purchase consideration for the acquisition of SolarBOS was $6.4 million, which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement. The acquisition was financed through cash on hand.

The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and approximated $2.9 million, all of which is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the solar renewable energy markets.

The allocation of the purchase consideration to the fair value of the assets acquired and liabilities assumed is as follows as of the date of the acquisition (in thousands):

Cash	$	915
Working capital	680
Property, plant and equipment	483
Acquired intangible assets	1,450
Other assets	13
Other liabilities	(51		)
Goodwill	2,879
Fair value of purchase consideration	$	6,369

The intangible assets acquired in this acquisition consisted of the following (in thousands):

	Fair Value		Estimated Useful Life
Trademarks	$	300	3 years
Technology	450		9 years
Customer relationships	700		9 years
Total	$	1,450

During the three and six month periods ended June 30, 2019, the Company incurred $4 thousand of acquisition-related costs. The Company did not incur any acquisition-related costs during the first half of 2018.

Senior Credit Agreement

On January 24, 2019, the Company entered into a Sixth Amended and Restated Credit Agreement ("2019 Senior Credit Agreement"), which amends and restates the Company’s Fifth Amended and Restated Credit Agreement dated December 9, 2015, and provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million. The Company can request additional financing from the lenders to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Senior Credit Agreement. The 2019 Senior Credit Agreement contains three financial covenants. As of June 30, 2019, the Company is in compliance with all three covenants.

(10) EQUITY-BASED COMPENSATION

On May 4, 2018, the shareholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2018 Equity Incentive Plan (the "2018 Plan"). The 2018 Plan provides for the issuance of up to 1,000,000 shares of common stock and supplements the remaining shares available for issuance under the existing Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "2015 Plan"). Both the 2018 Plan and the 2015 Plan allow the Company to grant equity-based incentive compensation awards, in the form of non-qualified options, restricted shares, restricted stock units, performance shares, performance stock units, and stock rights to eligible participants.

In 2016, the shareholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") which allows the Company to grant awards of shares of the Company's common stock to non-employee Directors of the Company and permits the Directors to defer receipt of such shares pursuant to the terms of the Non-Employee Directors Plan.

Equity Based Awards - Settled in Stock

The following table sets forth the number of equity-based awards granted during the six months ended June 30, which will convert to shares upon vesting, along with the weighted average grant date fair values:

	2019			2018
Awards	Number of Awards (1)	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value
Performance stock units	145,420	$	40.55	132,288	$	33.35
Restricted stock units	117,821	$	39.37	69,055	$	33.41
Deferred stock units	7,509	$	37.95	10,255	$	35.96
Common shares	7,509	$	37.95	2,113	$	35.50

(1) Performance stock units granted will convert to shares based on the Company's actual return on invested capital ("ROIC") relative to the ROIC targeted for the performance period ended December 31, 2019.

(2) Performance stock units granted in 2018 which will convert to 126,337 shares to be issued in the first quarter of 2021, representing 95.5% of the targeted 2018 award, based on the Company’s actual ROIC compared to ROIC target for the performance period ended December 31, 2018.

Equity Based Awards - Settled in Cash

The Company's equity-based liability includes awards under a management stock purchase plan. As of June 30, 2019, the Company's total share-based liabilities recorded on the consolidated balance sheet were $26.1 million, of which $21.5 million was included in non-current liabilities. The share-based liabilities as of December 31, 2018 were $38.4 million, of which $23.6 million was included in non-current liabilities.

During the six-months ended June 30, 2019, the Company paid $8.9 million to participants of cash-settled performance stock units awarded in 2016. The participants earned 200% of the target, or 256,000 units, which were converted to cash and valued at the trailing 90-day closing price of the Company's common stock as of December 31, 2018.

Management Stock Purchase Plan

The Management Stock Purchase Plan ("MSPP") provides participants the ability to defer a portion of their compensation, convertible to unrestricted investments, restricted stock units, or a combination of both, or defer a portion of their Directors’ fees, convertible to restricted stock units. Employees eligible to defer a portion of their compensation also receive a company-matching award in restricted stock units equal to a percentage of their compensation.

The deferrals and company-matching are credited to an account that represents a share-based liability. The portion of the account deferred to unrestricted investments is measured at fair market value of the unrestricted investments, and the portion of the account deferred to restricted stock units and company-matching restricted stock units is measured at a 200-day average of the Company stock price. The account will be converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.

The following table provides the number of restricted stock units credited to active participant accounts and the payments made with respect to restricted stock units issued under the MSPP during the six months ended June 30,:

	2019		2018
Restricted stock units credited	55,513		69,514
Share-based liabilities paid (in thousands)	$	5,742	$	4,717

(11) FAIR VALUE MEASUREMENTS

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. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities.

• Level 3 - Inputs that are unobservable inputs for the asset or liability.

The Company had no financial assets or liabilities measured at fair value on a recurring basis at June 30, 2019 and December 31, 2018. As of June 30, 2019, the Company does not have any financial instrument for which the carrying value differs from its fair value. At December 31, 2018, the Company's only financial instrument for which the carrying value differs from its fair value was the Company's Senior Subordinated 6.25% Notes, which were redeemed on February 1, 2019. At December 31, 2018, the fair value of the outstanding debt, net of unamortized debt issuance costs, was $210.8 million compared to its carrying value of $210.4 million.

(12) LEASES

The Company's leases are classified as operating leases and consist of manufacturing facilities, distribution centers, office space, vehicles and equipment. For leases with terms greater than twelve months, at lease commencement the Company recognizes a right-of-use asset and a lease liability. The initial lease liability is recognized at the present value of remaining lease payments over the lease term. Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheet. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups. Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.

Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from one month to fifteen years. The exercise of lease renewal options is at the Company's sole discretion. As of June 30, 2019, the Company's renewal options are not part of the Company's operating lease assets and operating lease liabilities. Certain leases also include options to purchase at fair value the underlying leased asset at the Company's sole discretion.

The Company uses the its incremental borrowing rate based on information available at the commencement date of a lease in determining the present value of lease payments as the rates implicit in most of the Company's leases are not readily determinable.

Upon adoption of ASU 2016-02 on January 1, 2019, the unrecognized deferred gain related to sale-leaseback transactions was recorded as a cumulative-effect adjustment to increase retained earnings, net of related income tax effects.

(13) EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS

The Company has incurred exit activity costs and asset impairment charges as a result of its 80/20 simplification and portfolio management initiatives. These initiatives have resulted in the identification of low-volume, low margin, internally-produced products which have been or will be outsourced or discontinued, the simplification of processes, and in the sale and exiting of less profitable businesses or products lines.

Exit activity costs were incurred during the six months ended June 30, 2019 which related to contract terminations, moving and closing costs, and severance incurred as a result of process simplification initiatives. No facilities were closed during the six months ended June 30, 2019.

During the six months ended June 30, 2018, the Company incurred exit activity costs resulting from the above initiatives. In conjunction with these initiatives, the Company closed one facility during the first half of 2018 and sold and leased back another facility which resulted in a gain, which was partially offset by inventory impairment charges incurred for discontinued products.

This segment's services and products are provided directly to developers, power companies, solar energy contractors, and institutional and commercial growers of plants.

As of June 30, 2019, we operated 41 facilities, comprised of 29 manufacturing facilities, five distribution centers, and seven offices, which are located in 18 states, Canada, China, and Japan, and are able to accommodate our capacity needs to meet current levels of demand throughout North America and, to a lesser extent, Asia.

Business Strategy

Our business strategy focuses on accelerating the growth and financial returns of the Company. We strive to deliver best-in-class, sustainable value creation for our shareholders, customers and team members, and we believe this can be achieved from a transformational change in the Company’s portfolio and strong operating performance. Our business strategy has four key elements, or "pillars," which are: operational excellence, innovation, portfolio management, and acquisitions as a strategic accelerator.

Operational excellence is our first pillar in this strategy. We focus on reducing complexity, adjusting costs and simplifying our product offering through 80/20 initiatives (“80/20”). 80/20 is the practice of focusing on our largest and best opportunities (the “80”) and eliminating complexity associated with less profitable opportunities (the “20”). The execution of 80/20 across our businesses, along with in-lining and market rate of demand replenishment initiatives, has and will continue to improve our service levels, overall profitability, and efficiency in the deployment of capital.

Innovation is our second strategic pillar. Our focus is on making innovation a strong competency across our organization to ensure we consistently bring new products, better processes, and value added services to our markets and customers. We are focused on delivering solutions that create more relevance for our end customers, and position our team as a trusted and reliable partner. Our trade focus initiatives are focused on connecting with our end user groups to better understand their needs and the market challenges we need to solve. This effort is expected to produce ideas and opportunities that generate profitable and sustainable growth for us and enhance the value we provide our customers. Our focus on innovation is centered on our current end markets, including, postal and parcel products, infrastructure, renewable energy and conservation. These respective markets are expected to grow based on demand for: centralized mail and parcel delivery systems, including solutions for the last mile of delivery; energy sources not dependent on fossil fuels, crops utilized in medical and recreational products, and the growing demand for locally grown produce.

The third pillar of our strategy is portfolio management, which is a natural adjunct to the 80/20 initiative. Using the 80/20 process, we conduct strategic reviews of our customers and end markets, and allocate leadership time, capital and resources to the platforms and businesses having the greatest potential revenues, profits and margins. As a result, we have sold and divested businesses and product lines which have helped contribute to the Company's realization of a higher rate of return on invested capital. We view portfolio management as a continuous process that will remain an important part of our strategy as we look to improve Gibraltar's long-term financial performance.

23

The fourth pillar of our strategy is acquisitions. We have targeted four key markets in which to make strategic acquisitions which are served by existing platforms within the Company. The target markets include: postal, parcel and storage solutions; infrastructure; renewable energy; and conservation. These platforms are all in large markets in which the underlying trends for customer convenience and safety, energy-savings and resource conservation are of increasing importance and are expected to drive long-term demand. We believe these markets also offer the opportunity for higher returns on our investments than those we have generated in the past. The acquisitions of Rough Brothers Manufacturing, Inc., RBI Solar, Inc., and affiliates, collectively known as "RBI" in June 2015, Nexus Corporation ("Nexus") in October 2016, Package Concierge in February 2017, and most recently, SolarBOS in August 2018, were the direct result of this fourth pillar strategy. We also consider businesses outside of these four markets, as we continually search out opportunities to grow our business in large markets with expected growth in demand for the foreseeable future, where we can add value through our manufacturing expertise, 80/20 process and purchasing synergies.

Overall, we believe our business strategy has enabled us to achieve stronger financial results, make more efficient use of capital and deliver higher shareholder returns. Going forward, we will continue to improve upon our operational excellence, optimize our assets and working capital efficiency, and invest in innovation and new product development to drive profitable and sustainable growth.

Recent Developments

On January 2, 2019, the Company appointed William T. Bosway as President and Chief Executive Officer of the Company and a member of the Board of Directors. Over the past 29 years, Mr. Bosway has worked for two Fortune 500 industrial companies and brings to the Company strong leadership skills and significant experience in acquisitions, driving organic growth, lean manufacturing and continuous improvement techniques.

On March 18, 2019, the Company appointed Patrick M. Burns as Chief Operating Officer. In his position as Chief Operating Officer, Mr. Burns will be responsible for all aspects of Gibraltar’s day to day operations across its businesses and such other executive duties as he is assigned from time to time by the Board of Directors and the Chief Executive Officer.

On January 24, 2019, we entered into the Company's Sixth Amended and Restated Credit Agreement (the "Senior Credit Agreement") which includes a 5-year, $400 million revolving credit facility. The Senior Credit Agreement also provides the Company the opportunity, upon request, to increase the amount of the revolving credit facility to $700 million.

In conjunction with entering into the Senior Credit Agreement on February 1, 2019, the Company redeemed all $210 million of its outstanding 6.25% Senior Subordinated Bonds. The amended Senior Credit Agreement provides the Company with access to capital and improves our financial flexibility.

On August 21, 2018, the Company acquired all of the outstanding stock of SolarBOS for an aggregate purchase price of $6.4 million which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement. The acquisition was financed through cash on hand. SolarBOS is a provider of electrical balance of systems products, which consists of electrical components such as wiring, switches, and combiner boxes that support photovoltaic systems, for the U.S. solar renewable energy market. The results of operations of SolarBOS have been included in the Renewable Energy and Conservation segment of the Company's consolidated financial statements from the date of acquisition.

Economic Conditions

The end markets our businesses serve are subject to economic conditions that are influenced by various factors. These factors include but are not limited to changes in general economic conditions, interest rates, exchange rates, commodity costs, demand for residential construction, demand for repair and remodeling, governmental policies and funding, tax policies and incentives, tariffs, trade policies, the level of non-residential construction and infrastructure projects, need for protection of high value assets, demand for renewable energy sources, and climate change. We believe the key elements of our strategy will allow us to respond timely to changes in these factors.

Results of Operations

Three Months Ended June 30, 2019 Compared to the Three Months Ended June 30, 2018

The following table sets forth selected results of operations data (in thousands) and its percentage of net sales for the three months ended June 30:

	2019					2018
Net sales	$	262,655		100.0	%	$	266,036	100.0	%
Cost of sales	199,097			75.8	%	195,533		73.5	%
Gross profit	63,558			24.2	%	70,503		26.5	%
Selling, general, and administrative expense	36,952			14.1	%	38,229		14.4	%
Income from operations	26,606			10.1	%	32,274		12.1	%
Interest expense	219			0.0	%	3,130		1.1	%
Other (income) expense	(13		)	0.0	%	13		0.0	%
Income before taxes	26,400			10.1	%	29,131		11.0	%
Provision for income taxes	6,487			2.5	%	6,294		2.4	%
Net income	$	19,913		7.6	%	$	22,837	8.6	%

The following table sets forth the Company’s net sales by reportable segment for the three months ended June 30, (in thousands):

	2019			2018			Total Change
Net sales:
Residential Products	$	130,433		$	131,128		$	(695	)
Industrial and Infrastructure Products	56,547			61,561			(5,014		)
Less: Intersegment sales	(329		)	(368		)	39
Net Industrial and Infrastructure Products	56,218			61,193			(4,975		)
Renewable Energy and Conservation	76,004			73,715			2,289
Consolidated	$	262,655		$	266,036		$	(3,381	)

Consolidated net sales decreased by $3.4 million, or 1.2%, to $262.7 million for the three months ended June 30, 2019 compared to the three months ended June 30, 2018. The 1.2% decrease was the net result of a 5.2% decrease in volume and a 2.7% increase in pricing to customers. Growth in our Renewable Energy and Conservation segment, including the contribution from our prior year acquisition of SolarBOS, and essentially flat revenues in our Residential Products segment were more than offset by lower demand in our Industrial business.

Net sales in our Residential Products segment decreased 0.5%, or $0.7 million, to $130.4 million for the three months ended June 30, 2019 compared to $131.1 million for the three months ended June 30, 2018. The slight decrease from the prior year quarter was the result of lower demand for our building products, due in part to unfavorable weather earlier in the quarter and labor shortages, largely offset by carryover customer selling price increases implemented during the second half of 2018.

Net sales in our Industrial and Infrastructure Products segment decreased 8.2%, or $5.0 million, to $56.2 million for the three months ended June 30, 2019 compared to $61.2 million for the three months ended June 30, 2018. Volumes for our core expanded metal products in the Industrial business were lower as customers made greater use of their existing inventories as steel prices declined during the quarter. Partially offsetting this decrease was increased volume in the Infrastructure business. In addition, during the quarter, we built growing backlogs in both our perimeter security solutions and infrastructure products.

25

Net sales in our Renewable Energy and Conservation segment increased 3.1%, or $2.3 million, to $76.0 million for the three months ended June 30, 2019 compared to $73.7 million for the three months ended June 30, 2018. The increase was the result of strong demand in our greenhouse solutions and a $3.2 million contribution from the prior year acquisition of SolarBOS. Partially offsetting this increase, as expected, were lower revenues in our solar business. We proactively paused on new solar tracker projects during the quarter while implementing field modifications to existing installations, and expect that these new installation projects will proceed as planned in the second half of 2019. We built growing backlogs in the segment during the quarter for both our greenhouse and solar solutions.

Our consolidated gross margin decreased to 24.2% for the three months ended June 30, 2019 compared to 26.5% for the three months ended June 30, 2018. This decrease was the result of an unfavorable alignment of material costs to customer selling prices, volume and incremental costs incurred for planned field improvements for our tracker solution. Benefits from our 80/20 simplification initiatives partially offset the decrease in margin.

Selling, general, and administrative (SG&A) expenses decreased by $1.3 million, or 3.3%, to $37.0 million for the three months ended June 30, 2019 from $38.2 million for the three months ended June 30, 2018. The $1.3 million decrease was the result of $4.8 million of lower performance-based compensation expenses, partially offset by a $1.7 million increase in senior leadership transition costs and a $1.4 million increase in exit activity costs related to our simplification initiatives, as compared to the prior year quarter. SG&A expenses as a percentage of net sales decreased to 14.1% for the three months ended June 30, 2019 compared to 14.4% for the three months ended June 30, 2018.

The following table sets forth the Company’s income from operations and income from operations as a percentage of net sales by reportable segment for the three months ended June 30, (in thousands):

	2019					2018					Total Change
Income from operations:
Residential Products	$	20,778		15.9	%	$	24,196		18.5	%	$	(3,418	)
Industrial and Infrastructure Products	4,069			7.2	%	6,604			10.8	%	(2,535		)
Renewable Energy and Conservation	9,649			12.7	%	9,556			13.0	%	93
Unallocated Corporate Expenses	(7,890		)	(3.0	)%	(8,082		)	(3.0	)%	192
Consolidated income from operations	$	26,606		10.1	%	$	32,274		12.1	%	$	(5,668	)

Our Residential Products segment generated an operating margin of 15.9% during the three months ended June 30, 2019 compared to 18.5% during the three months ended June 30, 2018. The decrease resulted from an unfavorable alignment of material costs to customer selling prices, reduced leverage on lower volume, and unfavorable product mix, partially offset by continued benefits from 80/20 simplification initiatives.

Our Industrial and Infrastructure Products segment generated an operating margin of 7.2% during the three months ended June 30, 2019 compared to 10.8% during the three months ended June 30, 2018. The decrease in operating margin was the result of volume, an unfavorable product mix and a less favorable alignment of material costs to pricing, partially offset by the continued benefit from the Company's 80/20 initiatives.

The Renewable Energy and Conservation segment generated an operating margin of 12.7% in the current year quarter compared to 13.0% in the prior year quarter. The decrease in operating margin was largely the result of $2.3 million in incremental costs related to the planned field improvements for our solar tracker solution which was largely offset by a favorable alignment of material costs to customer selling prices and mix.

Unallocated corporate expenses decreased $0.2 million from $8.1 million during the three months ended June 30, 2018 to $7.9 million during the three months ended June 30, 2019. This decrease from the prior year quarter was due to lower performance-based compensation expenses as compared to the prior year quarter nearly offset by senior leadership transition costs and exit activity costs incurred during the quarter.

Interest expense decreased by $2.9 million to $0.2 million for the three months ended June 30, 2019 compared to $3.1 million for the three months ended June 30, 2018. The decrease in expense resulted from the redemption of the Company's outstanding 6.25% Senior Subordinated Notes during the first quarter of 2019. During the three months ended June 30, 2019 and 2018, no amounts were outstanding under our then applicable revolving credit facility.

26

We recognized a provision for income taxes of $6.5 million and $6.3 million, with effective tax rates of 24.6% and 21.6% for the three months ended June 30, 2019, and 2018, respectively. The effective tax rate for the second quarter of 2019 was greater than the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences partially offset by favorable discrete items. The effective tax rate for the second quarter of 2018 exceeded the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences largely offset by favorable discrete items, including a $1.9 million tax benefit related to performance share unit vesting.

Six Months Ended June 30, 2019 Compared to the Six Months Ended June 30, 2018

The following table sets forth selected results of operations data (in thousands) and its percentage of net sales for the six months ended June 30:

	2019				2018

Net income	$	26,258	5.4	%	$	31,189		6.5	%

The following table sets forth the Company’s net sales by reportable segment for the six months ended June 30, (in thousands):

	2019			2018			Total Change
Net sales:
Residential Products	$	234,142		$	235,076		$	(934	)
Industrial and Infrastructure Products	111,735			116,185			(4,450		)
Less: Intersegment sales	(646		)	(589		)	(57		)
Net Industrial and Infrastructure Products	111,089			115,596			(4,507		)
Renewable Energy and Conservation	144,841			130,701			14,140
Consolidated	$	490,072		$	481,373		$	8,699

Consolidated net sales increased by $8.7 million, or 1.8%, to $490.1 million for the six months ended June 30, 2019 compared to the six months ended June 30, 2018. The 1.8% increase, the result of a 4.1% increase in pricing to customers, was partially offset by a 3.5% decrease in volume. Volume decline in our Industrial and Infrastructure Products segment was more than offset by strong growth in our Renewable Energy and Conservation segment which included a $5.8 million contribution from the prior year acquisition of SolarBOS.

Net sales in our Residential Products segment decreased 0.4%, or $0.9 million, to $234.1 million for the six months ended June 30, 2019 compared to $235.1 million in the six months ended June 30, 2018. The slight decrease from the prior year was the result of lower demand for our building products largely offset by carryover customer selling price increases implemented during the second half of 2018.

27

Net sales in our Industrial and Infrastructure Products segment decreased 3.9%, or $4.5 million, to $111.1 million for the six months ended June 30, 2019 compared to $115.6 million for the six months ended June 30, 2018. Volumes for our core expanded metal products in the Industrial business were lower as customers made greater use of their existing inventories as steel prices declined during the first half of the year. Partially offsetting this decrease was increased volume in the Infrastructure business. In addition, we built growing backlogs in both our perimeter security solutions and infrastructure products during the six months ended June 30, 2019.

Net sales in our Renewable Energy and Conservation segment increased 10.8%, or $14.1 million, to $144.8 million for the six months ended June 30, 2019 compared to $130.7 million for the six months ended June 30, 2018. The increase was the result of strong demand for our greenhouse solutions, the impact from our innovative products, and a $5.8 million contribution from the prior year acquisition of SolarBOS. We built growing backlogs in the segment for both our greenhouse and solar solutions during the six months ended June 30, 2019.

Our consolidated gross margin decreased to 21.9% for the six months ended June 30, 2019 compared to 24.7% for the six months ended June 30, 2018. This decrease was the result of an unfavorable alignment of material costs to customer selling prices, volume leverage and incremental costs incurred for planned field improvements for our tracker solution. Benefits from our 80/20 simplification initiatives partially offset the decrease in margin.

Selling, general, and administrative (SG&A) expenses decreased by $2.4 million, or 3.3%, to $70.3 million for the six months ended June 30, 2019 from $72.7 million for the six months ended June 30, 2018. The $2.4 million decrease was primarily due to a $7.1 million decrease in performance-based compensation expenses, partially offset by a $3.7 million increase in senior leadership transition costs and a $2.1 million increase in exit activity costs related to our simplification initiatives. SG&A expenses as a percentage of net sales decreased to 14.3% in the six months ended June 30, 2019 compared to 15.1% in the six months ended June 30, 2018.

The following table sets forth the Company’s income from operations and income from operations as a percentage of net sales by reportable segment for the six months ended June 30, (in thousands):

	2019					2018					Total Change
Income from operations:
Residential Products	$	32,868		14.0	%	$	37,434		15.9	%	$	(4,566	)
Industrial and Infrastructure Products	8,198			7.4	%	9,206			8.0	%	(1,008		)
Renewable Energy and Conservation	11,281			7.8	%	13,618			10.4	%	(2,337		)
Unallocated Corporate Expenses	(15,175		)	(3.1	)%	(14,141		)	(2.9	)%	(1,034		)
Consolidated income from operations	$	37,172		7.6	%	$	46,117		9.6	%	$	(8,945	)

Our Residential Products segment generated an operating margin of 14.0% during the six months ended June 30, 2019 compared to 15.9% during the six months ended June 30, 2018. The decrease in operating margin was due to an unfavorable alignment of material costs to customer selling prices, reduced leverage on lower volume, and unfavorable product mix, partially offset by benefits from 80/20 simplification initiatives.

Our Industrial and Infrastructure Products segment generated an operating margin of 7.4% during the six months ended June 30, 2019 compared to 8.0% during the six months ended June 30, 2018. The decrease in operating margin was the result of volume and an unfavorable alignment of material costs to pricing, which were partially offset by operational efficiencies resulting from the Company's 80/20 initiatives.

The Renewable Energy and Conservation segment generated an operating margin of 7.8% during the first half of the current year compared to 10.4% in the same period of the prior year. The decrease in operating margin was largely the result of additional costs related to the field improvements for our solar tracker solution which more than offset the benefits of favorable alignment of material costs to customer selling prices and volume leverage.

Unallocated corporate expenses increased $1.0 million from $14.1 million during the six months ended June 30, 2018 to $15.2 million during the six months ended June 30, 2019. This increase was due to senior leadership transition costs and exit activity costs charges partially offset by a decrease in performance-based compensation expenses.

28

The Company recorded other expense of $0.6 million for the six months ended June 30, 2019 and other income of $0.6 million for the six months ended June 30, 2018. The increase in other expense from the prior year was primarily the result of foreign currency fluctuations.

Interest expense decreased by $4.1 million to $2.3 million for the six months ended June 30, 2019 compared to $6.4 million for the six months ended June 30, 2018. The decrease in expense resulted from the redemption of the Company's outstanding 6.25% Senior Subordinated Notes during the first quarter of 2019. During the six months ended June 30, 2019 and 2018, no amounts were outstanding under our then applicable revolving credit facility.

We recognized a provision for income taxes of $8.1 million and $9.1 million, with effective tax rates of 23.5% and 22.6% for the six months ended June 30, 2019, and 2018, respectively. The effective tax rate for the six months ended June 30, 2019 exceeded the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences partially offset by favorable discrete items. The effective tax rate for the six months ended June 30, 2018 exceeded the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences partially offset by favorable discrete items, including a $1.9 million tax benefit related to performance share unit vesting.

Outlook

With our increased backlog levels built during the quarter, we expect positive end-market activity across our portfolio during the second half of the year. Our backlog demonstrates our ability to drive sustainable growth.

We continue to accelerate our 80/20 operating cadence, invest in new product development, and continue to get closer to our customers. We are actively assessing acquisitions that will strengthen our platforms, enhance our growth and margin profile, and expand our presence in the end markets that we serve.

The Company is maintaining its guidance for revenues and earnings for the full year 2019. We expect 2019 consolidated revenues to be in excess of $1 billion. GAAP EPS for full year 2019 is expected to be between $1.95 and $2.10, compared with $1.96 in 2018.

For the third quarter of 2019, the Company is expecting revenue in the range of $288 million to $298 million. GAAP EPS for the third quarter 2019 is expected to be between $0.71 and $0.78, compared to $0.60 in 2018.

Liquidity and Capital Resources

General

Our principal capital requirements are to fund our operations' working capital and capital improvements and to provide capital for acquisitions. We will continue to invest in growth opportunities as appropriate while focusing on working capital efficiency and profit improvement opportunities to minimize the cash invested to operate our businesses.

As of June 30, 2019, our liquidity of $475.9 million consisted of $81.9 million of cash and $394.0 million of availability under our revolving credit facility as compared to liquidity of $587.8 million as of December 31, 2018 and $501.0 million as of June 30, 2018.

On January 24, 2019, we entered into the Company's Sixth Amended and Restated Credit Agreement (the "Senior Credit Agreement") which includes a 5-year, $400 million revolving credit facility. The Senior Credit Agreement also provides the Company the opportunity, upon request, to increase the amount under the revolving credit facility to $700 million.

Utilizing existing cash on hand, the Company repaid $210 million of 6.25% Senior Subordinated Notes on February 1, 2019. We believe that our resulting low leverage and increased borrowing capacity along with enhanced flexibility in our new Senior Credit Agreement, provide us with ample liquidity. We believe our liquidity, together with the cash expected to be generated from operations, should be sufficient to fund working capital needs and simplification initiatives. We continue to search for strategic acquisitions. Larger acquisitions may require additional borrowings and/or the issuance of our common stock or other securities.

29

Our Senior Credit Agreement provides the Company with liquidity and capital resources for use by our U.S. operations. Historically, our foreign operations have generated cash flow from operations sufficient to invest in working capital and fund their capital improvements. As of June 30, 2019, our foreign subsidiaries held $23.0 million of cash in U.S. dollars, of which $13.9 million is available to be repatriated to the U.S. tax-free. Subsequent cash generated by our foreign subsidiaries will be reinvested into their operations.

Over the long-term, we expect that future investments, including strategic business opportunities such as acquisitions, may be financed through a number of sources, including internally available cash, availability under our revolving credit facility, new debt financing, the issuance of equity securities, or any combination of the above. Any potential acquisitions are evaluated based on our acquisition strategy, which includes the enhancement of our existing products, operations, or capabilities, expanding our access to new products, markets, and customers, and the improvement of shareholder value. Our 2018 acquisition of SolarBOS was funded by cash on hand.

These expectations are forward-looking statements based upon currently available information and may change if conditions in the credit and equity markets deteriorate or other circumstances change. To the extent that operating cash flows are lower than current levels, or sources of financing are not available or not available at acceptable terms, our future liquidity may be adversely affected.

Cash Flows

The following table sets forth selected cash flow data for the six months ended June 30, (in thousands):

	2019			2018
Cash provided by (used in):
Operating activities	$	6,486		$	(3,803	)
Investing activities	(6,469		)	(775		)
Financing activities	(216,176		)	(5,890		)
Effect of foreign exchange rate changes	1,035			(1,069		)
Net decrease in cash and cash equivalents	$	(215,124	)	$	(11,537	)

During the six months ended June 30, 2019, net cash provided by operating activities totaling $6.5 million was primarily driven by net income of $26.3 million and $18.7 million of non-cash charges including depreciation, amortization, stock compensation and other charges, offset by an investment in working capital and other net assets of $38.5 million. Net cash used in operating activities for the six months ended June 30, 2018 totaled $3.8 million was primarily driven by an investment in working capital and other net assets of $50.2 million, partially offset by net income of $31.2 million and $15.2 million from non-cash charges including depreciation, amortization, stock compensation, and exit activities.

During the six months ended June 30, 2019, the cash invested in working capital and other net assets of $38.5 million included a $41.2 million increase in accounts receivable, a $9.8 million decrease in accrued expenses and other non-current liabilities, and a $5.0 million increase in other assets, which was partially offset by a $13.5 million decrease in inventory and a $4.0 million increase in accounts payable. The increase in accounts receivable primarily relates to seasonal increases in manufacturing activity. The decrease in accrued expenses and other non-current liabilities was due to payments made pursuant to the Company's performance based incentive plans, interest on the redemption of the Company's 6.25% Senior Subordinated Notes on February 1, 2019, and accrued customer rebates, partially offset by costs correlated to the timing of customer payments. The decrease in inventory was driven by planned inventory management reduction initiatives. Total other current assets and other assets increased due to the timing of prepaid expenses. Accounts payable increased due to the seasonal increase in manufacturing activity.

Net cash used in investing activities for the six months ended June 30, 2019 of $6.5 million consisted of capital expenditures of $6.2 million and payment of $0.3 million related to the final purchase adjustment for the acquisition of SolarBOS. Net cash provided by investing activities for the six months ended June 30, 2018 of $0.8 million was the result of capital expenditures of $3.7 million and net proceeds of $2.9 million from the sale and lease-back of property and equipment.

30

Net cash used in financing activities for the six months ended June 30, 2019 of $216.2 million primarily consisted of long term debt repayments for the repayment of the $210.0 million of 6.25% Senior Subordinated Notes along with $2.0 million in other debt repayments, purchases of treasury stock of $3.2 million, and payment of debt issuance costs of $1.2 million, partially offset by proceeds received from the issuance of common stock of $0.2 million from stock options exercised. Net cash used in financing activities for the six months ended June 30, 2018 of $5.9 million consisted of the purchase of treasury stock of $6.0 million due to a large number of performance awards that vested in June 2018 and payment of long-term debt borrowings of $0.4 million partially offset by the proceeds received from the issuance of common stock of $0.5 million.

Senior Credit Agreement

Our new 2019 Senior Credit Agreement provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million.

Interest rates on the revolving credit facility are based on the LIBOR plus 1.125%. In addition, the revolving credit facility is subject to an undrawn commitment fee ranging between 0.15% and 0.25% based on the Total Leverage Ratio and the daily average undrawn balance.

CONSOLIDATED FINANCIAL STATEMENTS

CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited consolidated financial statements have been prepared by management in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for the fair presentation of results for the interim period have been included. The Company's operations are seasonal; for this and other reasons, financial results for any interim period are not necessarily indicative of the results expected for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual Form 10-K for the year ended December 31, 2018.

The balance sheet at December 31, 2018 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS

RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-02 Leases (Topic 842)	The standard requires lessees to recognize most leases as assets and liabilities on the balance sheet, but record expenses on the statement of operations in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The standard also requires additional disclosures about leasing arrangements and requires a modified retrospective transition approach for existing leases, whereby the standard will be applied to the earliest year presented. The provisions of the standard are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.	The Company has adopted this standard using the modified retrospective approach and elected the transition method to initially apply the new leases standard to all leases that exist at January 1, 2019. Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019. The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period. The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows. Date of adoption: Q1 2019

Recent Accounting Pronouncements Not Yet Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-13 Financial Instruments - Credit Losses (Topic 326)	The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The provisions of this standard are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.	The Company is currently evaluating the requirements of this standard. The standard is not expected to have a material impact on the Company's financial statements. Date of adoption: Q1 2020

ACQUISITIONS

On August 21, 2018, the Company acquired all of the outstanding stock of SolarBOS. SolarBOS is a provider of electrical balance of systems products, which consists of electrical components such as wiring, switches, and combiner boxes that support photovoltaic systems, for the U.S. solar renewable energy market. The Company expects the acquisition of SolarBOS to enable the Company to provide complementary product offerings to its existing customers and strengthen its position in the solar renewable energy market. The results of SolarBOS have been included in the Company's consolidated financial results since the date of acquisition (within the Company's Renewable Energy and Conservation segment). The aggregate purchase consideration for the acquisition of SolarBOS was $6.4 million, which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement. The acquisition was financed through cash on hand.

The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and approximated $2.9 million, all of which is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the solar renewable energy markets.

The allocation of the purchase consideration to the fair value of the assets acquired and liabilities assumed is as follows as of the date of the acquisition (in thousands):

Cash	$	915
Working capital	680
Property, plant and equipment	483
Acquired intangible assets	1,450

EQUITY-BASED COMPENSATION

EQUITY-BASED COMPENSATION

On May 4, 2018, the shareholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2018 Equity Incentive Plan (the "2018 Plan"). The 2018 Plan provides for the issuance of up to 1,000,000 shares of common stock and supplements the remaining shares available for issuance under the existing Gibraltar Industries, Inc. 2015 Equity Incentive Plan (the "2015 Plan"). Both the 2018 Plan and the 2015 Plan allow the Company to grant equity-based incentive compensation awards, in the form of non-qualified options, restricted shares, restricted stock units, performance shares, performance stock units, and stock rights to eligible participants.

In 2016, the shareholders of the Company approved the adoption of the Gibraltar Industries, Inc. 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") which allows the Company to grant awards of shares of the Company's common stock to non-employee Directors of the Company and permits the Directors to defer receipt of such shares pursuant to the terms of the Non-Employee Directors Plan.

Equity Based Awards - Settled in Stock

The following table sets forth the number of equity-based awards granted during the six months ended June 30, which will convert to shares upon vesting, along with the weighted average grant date fair values:

	2019			2018
Awards	Number of Awards (1)	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value
Performance stock units	145,420	$	40.55	132,288	$	33.35
Restricted stock units	117,821	$	39.37	69,055	$	33.41
Deferred stock units	7,509	$	37.95	10,255	$	35.96
Common shares	7,509	$	37.95	2,113	$	35.50

(1) Performance stock units granted will convert to shares based on the Company's actual return on invested capital ("ROIC") relative to the ROIC targeted for the performance period ended December 31, 2019.

(2) Performance stock units granted in 2018 which will convert to 126,337 shares to be issued in the first quarter of 2021, representing 95.5% of the targeted 2018 award, based on the Company’s actual ROIC compared to ROIC target for the performance period ended December 31, 2018.

Equity Based Awards - Settled in Cash

The Company's equity-based liability includes awards under a management stock purchase plan. As of June 30, 2019, the Company's total share-based liabilities recorded on the consolidated balance sheet were $26.1 million, of which $21.5 million was included in non-current liabilities. The share-based liabilities as of December 31, 2018 were $38.4 million, of which $23.6 million was included in non-current liabilities.

During the six-months ended June 30, 2019, the Company paid $8.9 million to participants of cash-settled performance stock units awarded in 2016. The participants earned 200% of the target, or 256,000 units, which were converted to cash and valued at the trailing 90-day closing price of the Company's common stock as of December 31, 2018.

Management Stock Purchase Plan

The Management Stock Purchase Plan ("MSPP") provides participants the ability to defer a portion of their compensation, convertible to unrestricted investments, restricted stock units, or a combination of both, or defer a portion of their Directors’ fees, convertible to restricted stock units. Employees eligible to defer a portion of their compensation also receive a company-matching award in restricted stock units equal to a percentage of their compensation.

The deferrals and company-matching are credited to an account that represents a share-based liability. The portion of the account deferred to unrestricted investments is measured at fair market value of the unrestricted investments, and the portion of the account deferred to restricted stock units and company-matching restricted stock units is measured at a 200-day average of the Company stock price. The account will be converted to and settled in cash payable to participants upon retirement or a termination of their service to the Company.

The following table provides the number of restricted stock units credited to active participant accounts and the payments made with respect to restricted stock units issued under the MSPP during the six months ended June 30,:

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

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. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities.

• Level 3 - Inputs that are unobservable inputs for the asset or liability.

The Company had no financial assets or liabilities measured at fair value on a recurring basis at June 30, 2019 and December 31, 2018. As of June 30, 2019, the Company does not have any financial instrument for which the carrying value differs from its fair value. At December 31, 2018, the Company's only financial instrument for which the carrying value differs from its fair value was the Company's Senior Subordinated 6.25% Notes, which were redeemed on February 1, 2019. At December 31, 2018, the fair value of the outstanding debt, net of unamortized debt issuance costs, was $210.8 million compared to its carrying value of $210.4 million.

Leases [Abstract]

Leases

LEASES

The Company's leases are classified as operating leases and consist of manufacturing facilities, distribution centers, office space, vehicles and equipment. For leases with terms greater than twelve months, at lease commencement the Company recognizes a right-of-use asset and a lease liability. The initial lease liability is recognized at the present value of remaining lease payments over the lease term. Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheet. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups. Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.

Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from one month to fifteen years. The exercise of lease renewal options is at the Company's sole discretion. As of June 30, 2019, the Company's renewal options are not part of the Company's operating lease assets and operating lease liabilities. Certain leases also include options to purchase at fair value the underlying leased asset at the Company's sole discretion.

Exit Activity Costs and Asset Impairments

Restructuring and Related Activities [Abstract]

EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS

EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS

The Company has incurred exit activity costs and asset impairment charges as a result of its 80/20 simplification and portfolio management initiatives. These initiatives have resulted in the identification of low-volume, low margin, internally-produced products which have been or will be outsourced or discontinued, the simplification of processes, and in the sale and exiting of less profitable businesses or products lines.

Exit activity costs were incurred during the six months ended June 30, 2019 which related to contract terminations, moving and closing costs, and severance incurred as a result of process simplification initiatives. No facilities were closed during the six months ended June 30, 2019.

During the six months ended June 30, 2018, the Company incurred exit activity costs resulting from the above initiatives. In conjunction with these initiatives, the Company closed one facility during the first half of 2018 and sold and leased back another facility which resulted in a gain, which was partially offset by inventory impairment charges incurred for discontinued products.

The following tables set forth the asset impairment charges and exit activity costs incurred by segment during the three and six months ended June 30, related to the restructuring activities described above (in thousands):

Accounting Policies [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-02 Leases (Topic 842)	The standard requires lessees to recognize most leases as assets and liabilities on the balance sheet, but record expenses on the statement of operations in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The standard also requires additional disclosures about leasing arrangements and requires a modified retrospective transition approach for existing leases, whereby the standard will be applied to the earliest year presented. The provisions of the standard are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.	The Company has adopted this standard using the modified retrospective approach and elected the transition method to initially apply the new leases standard to all leases that exist at January 1, 2019. Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019. The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period. The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows. Date of adoption: Q1 2019

Recent Accounting Pronouncements Not Yet Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2016-13 Financial Instruments - Credit Losses (Topic 326)	The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The provisions of this standard are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.	The Company is currently evaluating the requirements of this standard. The standard is not expected to have a material impact on the Company's financial statements. Date of adoption: Q1 2020
