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, such as the impact of the COVID-19 pandemic, 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, 2019.

The balance sheet at December 31, 2019 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. 2016-13 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 standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the modified retrospective approach through a cumulative-effect adjustment to retained earnings of $291,000, net of $96,000 of income taxes, on the opening consolidated balance sheet as of January 1, 2020. The Company's financial assets that are in the scope of the standard are contract assets and accounts receivables which are short-term in nature. Additionally, the Company has identified and implemented appropriate changes to the Company's business processes, policies and internal controls to support reporting and disclosures. Date of adoption: Q1 2020
ASU 2018-15 Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	The amendments in this update require an entity to apply the same requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract as the entity would for implementation costs incurred to develop or obtain internal-use software. The accounting for the service element is not affected by the amendments in this update.	The standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the prospective method of adoption, and the adoption did not have a material impact to the Company's financial statements. Date of adoption: Q1 2020

Recent Accounting Pronouncements Not Yet Adopted

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2019-12 Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes	The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and improve consistent application by clarifying and amending existing guidance. The amendments of this standard are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued, with the amendments to be applied on a respective, modified retrospective or prospective basis, depending on the specific amendment.	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 2021

(3) ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS

Accounts receivable consists of the following (in thousands):

	March 31, 2020			December 31, 2019
Trade accounts receivable	$	156,399		$	133,238
Costs in excess of billings	21,834			20,607
Total accounts receivables	178,233			153,845
Less allowance for doubtful accounts and contract assets	(5,781		)	(6,330		)
Accounts receivable	$	172,452		$	147,515

Refer to Note 4 "Revenue" concerning the Company's costs in excess of billings.

The Company is exposed to credit losses through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable and costs in excess of billings (collectively "accounts receivable") is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers' accounts receivables. Due to the short-term nature of such accounts receivable, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. Additionally, specific allowance amounts are established to record the appropriate provision for customers that no longer share risk characteristics similar with other accounts receivable. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company considered the current and expected future economic and market conditions surrounding the coronavirus ("COVID-19") pandemic and determined that the estimate of credit losses was not significantly impacted as of March 31, 2020.

Estimates are used to determine the allowance. It is based on assessment of anticipated payment and all other historical, current and future information that is reasonably available.

The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected.

Beginning balance as of January 1, 2020	$	6,330
Adoption of ASU 2016-13, cumulative-effect adjustment to retained earnings	387
Bad debt expense	69
Write-off charged against the allowance and other adjustments	(1,005		)
Ending balance as of March 31, 2020	$	5,781

The acquisitions of Delta Separations, Thermo Energy Systems and Apeks were funded from available cash on hand.

The Company incurred certain acquisition-related costs composed of legal and consulting fees. These costs were recognized as a component of selling, general, and administrative expenses in the consolidated statement of operations.

During the three months ended March 31, 2020, the Company incurred $1.3 million of acquisition-related costs. The Company did not incur any acquisition-related costs during the three months ended March 31, 2019.

In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. The Company considered the current and future macroeconomic and market conditions, along with its current market capitalization, projected cash flows and internal and external forecasts, and projections relating to the impact of the COVID-19 pandemic on each of its reporting units. The Company determined that a triggering event has not occurred which would require an interim impairment test to be performed.

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 three months ended March 31, which will convert to shares upon vesting, along with the weighted average grant date fair values:

	2020			2019
Awards	Number of Awards (1)	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value
Performance stock units	123,870	$	53.29	145,420	$	40.55
Restricted stock units	42,101	$	52.31	117,821	$	39.37

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance or market conditions. The number of shares to be issued may vary between 0% and 200% of the number of performance stock units granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on either the Company’s return on invested capital (“ROIC”) over a one-year period performance period or revenue, gross profit and operating profit thresholds over a two or three-year performance period. The Company's PSUs with a market condition are based on the ranking of the Company’s total shareholder return (“TSR”) performance, on a percentile basis, over a three year performance period compared to the S&P Small Cap Industrial sector, over the same three year performance period.

(2) Performance stock units granted in 2019 have converted to 168,688 shares to be issued to recipients in the first quarter of 2022, representing 116% of the targeted 2019 award, based on the Company’s actual ROIC compared to ROIC target for the performance period ended December 31, 2019.

Equity Based Awards - Settled in Cash

The Company's equity-based liability includes awards under a management stock purchase plan. As of March 31, 2020, the Company's total share-based liabilities recorded on the consolidated balance sheet were $28.7 million, of which $12.2 million was included in non-current liabilities. The share-based liabilities as of December 31, 2019 were $28.0 million, of which $13.2 million was included in non-current liabilities.

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 three months ended March 31,:

Overview

Gibraltar Industries, Inc. (the "Company") is a leading manufacturer and provider of products and services for the renewable energy, conservation, residential, industrial and infrastructure markets.

The Company operates and reports its results in the following three reporting segments:

• Renewable Energy and Conservation;

• Residential Products; and

• Industrial and Infrastructure Products.

The Company serves customers primarily in North America including renewable energy (solar) developers, institutional and commercial growers of food and plants, home improvement retailers, wholesalers, distributors, and contractors. As of March 31, 2020, we operated 45 facilities in 19 states, Canada, China and Japan which includes 33 manufacturing facilities and five distribution centers. Our operational infrastructure provides the necessary scale to support local, regional, and national customers in each of our markets.

Our businesses and the end markets that our businesses serve are subject to changes in economic conditions that are influenced by various factors that could cause actual results to differ materially from current expectations. Such factors include, but are not limited to:

• the impacts of the recent outbreak of the COVID-19 pandemic on the global economy, our customers, suppliers, employees, operations, business, liquidity and cash flows;

• general economic conditions and conditions in the particular markets in which we operate;

• changes in customer demand for residential construction, repair and remodeling, non-residential construction and infrastructure projects, botanical extraction equipment, and renewable energy sources;

22

• capital spending, competitive factors and pricing pressures;

• our ability to develop and launch new products in a cost-effective manner;

• our ability to realize synergies from newly acquired businesses, and our ability to derive expected benefits from restructuring, productivity initiatives, liquidity enhancing actions, and other cost reduction actions;

• changes in interest rates, exchange rates, commodity costs;

• changes in governmental policies and funding, tax policies and incentives, tariffs, trade policies;

• the need for protection of high value assets; and

• climate change.

The impact of the recent outbreak of COVID-19 pandemic on our future consolidated results of operations is uncertain and will depend on the duration of the outbreak and its impact on our customers, suppliers, employees and subcontractors. Refer to the Company's Outlook section in this management discussion and analysis for consideration relative to future periods. We are taking proactive measures to respond to the challenges to our business and are altering our operations accordingly to continue to serve our end markets and maintain the safety of our employees.

We believe the key elements of our strategy discussed below will allow us to respond timely to the challenges presented by the COVID-19 pandemic and changes in the other various factors that could cause our actual results to differ materially from current expectations.

Business Strategy

Gibraltar’s mission is to create compounding and sustainable value with strong leadership positions in higher growth, profitable end markets. At the beginning of 2019, after four years of steady improvement in operational execution and financial results under the leadership of Frank Heard, the Company announced the appointment of Bill Bosway as Chief Executive Officer, with Frank Heard vacating the CEO role and being appointed Executive Vice Chair of the Board through his planned retirement in March 2020. Under Mr. Bosway’s leadership, management completed a thorough evaluation of the markets the Company participates in, as well as its position in each market. This work solidified the Company’s strategy and defined plans to accelerate growth and further improve the Company’s margin profile, both through organic and inorganic investment. It has also helped focus and prioritize the Company's key investments to delivers increasing returns and sustainable value for its shareholders.

The Company migrated from a Four-Pillar strategy to a Three-Pillar strategy with the operating foundation focused on three core tenets: Business Systems, Portfolio Management, and Organizational Development.

1. Business Systems, which combines two of the Company's previous strategic pillars - operational excellence and product innovation is supported by an execution review of the Company's monthly business performance, implementation of key investments, information technology operating and digital systems performance, and new product and services innovation.

2. Portfolio Management, which combines the two other previous strategic pillars - acquisitions and portfolio management is focused on optimizing the Company’s business portfolio and ensuring our human and financial capital are invested to provide sustainable, profitable growth while expanding our relevance with customers and shaping our markets. The recent acquisitions of Apeks, LLC ("Apeks") in August 2019, Thermo Energy Systems, Inc. ("Thermo") in January 2020, and Delta Separations LLC and Teaching Tech LLC (collectively “Delta Separations”) in February 2020 were the direct result of our portfolio management strategy.

3. Organizational Development is the third pillar of our strategy. In order to execute Business Systems and Portfolio Management, the Company must have a strong organization to execute, and the organization must continuously develop and improve. The Company aspires to make our workplace the "Best Place to Work", by focusing on creating the best development and learning environment for our people, proactively operate businesses that mitigate environmental and climate related impacts, and engage and support the communities in which we are located. We believe doing so helps us attract and retain the best people, enhancing our ability to execute our business plans.

In addition to migrating from a Four-Pillar strategy to a Three-Pillar strategy, the Company:

• Implemented new management tools to complement our core 80/20 toolkit and drive improvements in our operating margins;

23

• Increased the percentage of our sales that are direct to end customers, allowing us to have a more meaningful connection with our end customers, providing the opportunity to better understand the challenges our customers face, and developing solutions to these challenges; and

• Continued to shift the focus of our portfolio to take advantage of rising tides in the renewable energy and conservation markets.

We believe the key elements of our strategy have, and will continue to enable us, to respond timely to changes in the end markets we serve, including evolving changes due to the outbreak of COVID-19. We have and expect to continue to examine the need for restructuring of our operations, including consolidation of facilities, reducing overhead costs, curtailing investments in inventory, and managing our business to generate incremental cash. We believe our enhanced strategy enabled us to better react to volatility in commodity costs and fluctuations in customer demand, along with helping to improve margins. We have used the improved cash flows generated by these initiatives to pay down debt, improve our liquidity position, and invest in growth initiatives. Overall, we continue to strive to achieve stronger financial results, make more efficient use of capital, and deliver higher shareholder returns.

Recent Developments

On February 13, 2020, the Company acquired the assets of California-based Delta Separations and Teaching Tech ("Delta Separations"), a privately held ethanol-based extraction systems manufacturer and training and laboratory design and operations consultative partner for $50 million in an all cash transaction.

Thermo is expected to contribute annual revenue at a run rate of approximately $75 million.

On August 30, 2019, the Company acquired all of the outstanding membership interests of Apeks LLC ("Apeks"), a designer and manufacturer of botanical oil extraction systems utilizing subcritical and supercritical carbon dioxide ("CO2"). The acquisition was financed through cash on hand of $12 million. Apeks had trailing twelve months of revenues as of June 30, 2019 of $17.7 million.

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 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. In connection with Mr. Bosway’s appointment, then Chief Executive Officer Frank Heard was appointed Executive Vice Chair of the Board and he announced his intention to retire on March 3, 2020.

Net Industrial and Infrastructure Products	49,523			54,871			(5,348		)
Consolidated	$	249,439		$	227,417		$	22,022

Consolidated net sales increased by $22.0 million, or 9.7%, to $249.4 million for the three months ended March 31, 2020 compared to the three months ended March 31, 2019. The 9.7% increase in revenue was driven by $15.7 million of sales generated from our acquisitions of Delta Separations and Thermo during the current year quarter and the prior year acquisition of Apeks. The organic growth in the quarter stemmed from a 2.8% increase in volume, primarily from our Renewable Energy and Conservation segment, which more than offset the volume decline in our Industrial and Infrastructure Products segment. Revenue in our Residential Products segment was essentially flat as compared to the prior year quarter.

Net sales in our Renewable Energy and Conservation segment increased 40.3%, or $27.7 million, to $96.5 million for the three months ended March 31, 2020 compared to $68.8 million for the three months ended March 31, 2019. Sales generated from the current year quarter acquisitions of Delta Separations and Thermo, along with the prior year acquisition of Apeks, contributed $15.7 million to the increase in the current year. In addition, strong organic growth was the result of healthy market dynamics and participation gains as evidenced by our 58% improvement in backlog year over year, or 13% on an organic basis.

25

Net sales in our Residential Products segment decreased 0.3%, or $0.3 million, to $103.4 million for the three months ended March 31, 2020 compared to $103.7 million for the three months ended March 31, 2019. The slight decrease from the prior year quarter was the result of product line simplification actions taken in 2019 and from lower volume for products sold directly to homeowners.

Net sales in our Industrial and Infrastructure Products segment decreased 9.7%, or $5.3 million, to $49.5 million for the three months ended March 31, 2020 compared to $54.9 million for the three months ended March 31, 2019. Increased volume in the Infrastructure business was more than offset by lower revenue in the Industrial businesses, driven by lower demand and lower steel prices impacting its core industrial products.

Our consolidated gross margin increased to 22.6% for the three months ended March 31, 2020 compared to 19.3% for the three months ended March 31, 2019. This increase was the result of improved operating execution compared to the prior year quarter which included $3.4 million of incremental costs for design refinement and field improvements for our solar tracking solution. Favorable alignment of material costs to customer selling prices, volume leverage and benefits from our 80/20 simplification initiatives also contributed to the improved gross margin year over year. Partially offsetting the above improvements were lower gross margins generated from our recent acquisitions.

Selling, general, and administrative (SG&A) expenses increased by $7.9 million, or 23.6%, to $41.2 million for the three months ended March 31, 2020 from $33.3 million for the three months ended March 31, 2019. The $7.9 million increase was largely the result of $3.7 million of incremental SG&A expenses recorded quarter over quarter for our recent acquisitions, along with costs incurred to effect the acquisitions closed during the quarter. SG&A expenses as a percentage of net sales increased to 16.5% for the three months ended March 31, 2020 compared to 14.7% for the three months ended March 31, 2019.

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 March 31, (in thousands):

	2020					2019					Total Change
Income from operations:
Renewable Energy and Conservation	$	5,699		5.9	%	$	1,632		2.4	%	$	4,067
Residential Products	13,725			13.3	%	12,090			11.7	%	1,635
Industrial and Infrastructure Products	3,989			8.1	%	4,129			7.5	%	(140		)
Unallocated Corporate Expenses	(8,223		)	(3.3	)%	(7,285		)	(3.2	)%	(938		)
Consolidated income from operations	$	15,190		6.1	%	$	10,566		4.6	%	$	4,624

The Renewable Energy and Conservation segment generated an operating margin of 5.9% in the current year quarter compared to 2.4% in the prior year quarter. The increase in operating margin was largely the result of $3.4 million of incremental costs incurred during the prior year quarter for design refinement and field improvements for our solar tracking solution. Volume leverage, improved operating execution and favorable alignment of material costs to customer selling prices also contributed to the improved margin year over year. Partially offsetting the above improvements were losses generated from our recent acquisitions which incurred seasonally lower volumes and include lower margin projects as compared to our organic margin profile.

Our Residential Products segment generated an operating margin of 13.3% during the three months ended March 31, 2020 compared to 11.7% during the three months ended March 31, 2019. The increase resulted from a favorable alignment of material costs to customer selling prices along with continued benefits from 80/20 simplification initiatives.

Our Industrial and Infrastructure Products segment generated an operating margin of 8.1% during the three months ended March 31, 2020 compared to 7.5% during the three months ended March 31, 2019. The increase in operating margin was the result of a more favorable alignment of material costs to customer selling prices, higher margin product mix and ongoing benefit from the Company's 80/20 initiatives.

Unallocated corporate expenses increased $0.9 million from $7.3 million during the three months ended March 31, 2019 to $8.2 million during the three months ended March 31, 2020. This increase from the prior year quarter was largely the result of costs incurred to effect the acquisitions closed during the quarter.

26

Interest income realized for the three months ended March 31, 2020 was negligible. The change from $2.1 million of interest expense incurred for the three months ended March 31, 2019 resulted from the redemption of the Company's outstanding 6.25% Senior Subordinated Notes during the first quarter of 2019. No amounts were outstanding under our revolving credit facility during the three months ended March 31, 2020 and 2019.

We recognized a provision for income taxes of $3.0 million and $1.6 million, with an effective tax rate of 19.8% for both the three months ended March 31, 2020, and 2019, respectively. The effective tax rate for the three months ended March 31, 2020 and 2019, respectively, was less than the U.S. federal statutory rate of 21% due to favorable discrete items partially offset by state taxes and nondeductible permanent differences.

Outlook

Gibraltar continues to accelerate growth and margin improvement through organic and inorganic investment in inherently attractive end markets that are vital to the economy’s core needs and less impacted by economic variables. Our higher growth businesses - renewable energy, commercial greenhouse growing, and processing - represented 39% of first quarter revenue and generated 58% growth in backlog as these markets continue to accelerate. The infrastructure business is also experiencing solid market growth and participation gains as reflected in backlog that has grown 13% over the prior year quarter.

The core residential building products businesses - ventilation, building accessories, and postal - delivered modest growth in the first quarter, but did see demand begin to slow after the end of the first quarter. The home improvement and industrial businesses have been the most impacted in today’s environment. Overall, the we expects demand in the immediate future to lag prior year until consumer confidence and spending improves. We have not seen a disruption from our suppliers. Our supply chain team remains in close contact with key suppliers and alternate supply sources to mitigate the risk of potential supply disruption.

We will continue to enhance our revenue and income streams and, backed by the strength of our balance sheet, will remain focused on executing our strategy, working to improve our business, and helping our team, customers, suppliers, and partners successfully navigate through today’s environment. We are leveraging our operating system - Business Systems, Portfolio Management, and Organization Development - to refine our business, strengthen the organization, and execute critical initiatives that will accelerate growth, profitability, asset utilization, and further improve return on invested capital.

Given the current economic environment and reduced visibility, it is difficult to provide guidance for the second quarter and full-year 2020. Therefore, we are going to rescind our previous guidance. However, we do expect to deliver positive earnings and generate cash from operations throughout 2020. We will revisit the practice of providing guidance as we complete the second quarter.

Liquidity and Capital Resources

Our principal capital requirements are to fund our operations' working capital and capital improvements and to provide capital for acquisitions. The following table sets forth our liquidity position as of:

(in thousands)	March 31, 2020		December 31, 2019
Cash and cash equivalents	$	85,966	$	191,363
Availability on revolving credit facility	394,100		393,991
	$	480,066	$	585,354

We believe that our cash on hand, lack of outstanding debt, and available borrowing capacity provided under the Senior Credit Agreement provide us with ample liquidity and capital resources to weather the economic impacts of the COVID-19 pandemic while continuing to invest in operational excellence, growth initiatives and the development of our organization. Given the economic uncertainty caused by the COVID-19 pandemic and federal, state and local governments response to it, we have currently paused our acquisition activities. We remain in contact with the companies aligned with our strategic initiatives and expect to re-engage in these acquisition processes when the economic impact becomes clearer. In the interim, we remain highly focused on managing our working capital, which may include adjusting scheduled deliveries of inventory to match current demand levels, closely monitoring customer credit and collection activities, and working to extend payment terms.

27

Our Senior Credit Agreement provides us with the 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 March 31, 2020, our foreign subsidiaries held $29.6 million of cash in U.S. dollars, of which $12.9 million is available to be repatriated to the U.S., net of $0.6 million of withholding tax. Subsequent cash generated by our foreign subsidiaries will be reinvested into their operations.

We are taking advantage of the option to defer remittance of the employer portion of Social Security tax as provided in the Coronavirus, Aid, Relief and Economic Security Act ("CARES Act"), and estimate that this deferral will allow us to retain approximately $4 million in cash during the remainder of 2020 that would have otherwise been remitted to the federal government. The deferred tax payments will be repaid equally in 2021 and 2022.

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. All 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, with the goal of creating compounding and sustainable shareholder value.

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 three months ended March 31, (in thousands):

	2020			2019
Cash (used in) provided by:

In addition to seasonal increases in inventory and trade receivables and payables, the investment in net working capital and other net assets was largely driven by an investment of $37.5 million in Thermo, one of our recent acquisitions, which was undercapitalized at purchase, along with the payments made during the quarter for the Company's performance based incentive plans, customer rebates, and settlements of multi-employer pension plans terminated during 2019.

Net cash used in operating activities of $37.5 million during the three months ended March 31, 2019 consisted of an investment in working capital and other net assets of $54.0 million offset by $10.2 million from non-cash charges including depreciation, amortization, stock compensation and other net charges as well as net income of $6.3 million.

Investing Activities

Net cash used in investing activities for the three months ended March 31, 2019 of $3.4 million consisted of capital expenditures of $3.1 million and a payment of $0.3 million related to the acquisition of SolarBOS.

28

Financing Activities

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Not applicable.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the risks discussed in “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operation, cash flows, and future prospects. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may materially adversely impact our business, financial condition, or operating results. We believe there have been no material changes from the risk factors previously disclosed in our Form 10-K. During the quarter ended March 31, 2020, there have been no material changes to the risk factors previously disclosed under Part I, Item 1A. “Risk Factors” in our 2019 Annual Report, except as follows:

The COVID-19 pandemic has significantly impacted worldwide economic conditions and could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

The COVID-19, or coronavirus, pandemic began to impact our operations late in the first quarter of 2020 and is likely to continue to affect our business as government authorities impose mandatory closures, work-from-home orders and social distancing protocols, seek voluntary facility closures or impose other restrictions to help control the spread of COVID-19. Although we cannot predict the duration or scope of the COVID-19 pandemic, current actions to control the spread of COVID-19 may adversely impact our business, including limiting our ability to implement our strategic growth initiatives, causing delays in our receipt of raw materials and other product components due to disruptions in our supply chain, limiting access to our distribution channels, reducing the availability of our workforce and subcontractors and increased threats of cyber attacks on our information technology infrastructure. The instability in global financial markets and unpredictable changes in our supply chain or our production capacity and customer demand resulting from the COVID-19 pandemic may pose material risk to our results of operations, financial condition, and cash flows. We are continuously monitoring the impact to our business and operations and taking action to mitigate the risks involved. However, prolonged disruption to the economy and the end markets we serve may have a material adverse impact our business, results of operations, financial condition, and cash flows.

Schedule Of Number Of Awards And Weighted Average Grant Date Fair Value

The following table sets forth the number of equity-based awards granted during the three months ended March 31, which will convert to shares upon vesting, along with the weighted average grant date fair values:

	2020			2019
Awards	Number of Awards (1)	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value

Restricted stock units	42,101	$	52.31	117,821	$	39.37

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance or market conditions. The number of shares to be issued may vary between 0% and 200% of the number of performance stock units granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on either the Company’s return on invested capital (“ROIC”) over a one-year period performance period or revenue, gross profit and operating profit thresholds over a two or three-year performance period. The Company's PSUs with a market condition are based on the ranking of the Company’s total shareholder return (“TSR”) performance, on a percentile basis, over a three year performance period compared to the S&P Small Cap Industrial sector, over the same three year performance period.

(2) Performance stock units granted in 2019 have converted to 168,688 shares to be issued to recipients in the first quarter of 2022, representing 116% of the targeted 2019 award, based on the Company’s actual ROIC compared to ROIC target for the performance period ended December 31, 2019.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles

Recent Accounting Pronouncements 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 standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the modified retrospective approach through a cumulative-effect adjustment to retained earnings of $291,000, net of $96,000 of income taxes, on the opening consolidated balance sheet as of January 1, 2020. The Company's financial assets that are in the scope of the standard are contract assets and accounts receivables which are short-term in nature. Additionally, the Company has identified and implemented appropriate changes to the Company's business processes, policies and internal controls to support reporting and disclosures. Date of adoption: Q1 2020
ASU 2018-15 Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	The amendments in this update require an entity to apply the same requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract as the entity would for implementation costs incurred to develop or obtain internal-use software. The accounting for the service element is not affected by the amendments in this update.	The standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the prospective method of adoption, and the adoption did not have a material impact to the Company's financial statements. Date of adoption: Q1 2020

The amendments of this standard are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued, with the amendments to be applied on a respective, modified retrospective or prospective basis, depending on the specific amendment.

ACQUISITIONS

ACQUISITIONS

On February 13, 2020, the Company purchased substantially all of the assets of Delta Separations, LLC, a California limited liability company, and Teaching Tech, LLC, a California limited liability company (collectively described as "Delta Separations"). Delta Separations was a privately-held engineering company primarily engaged in the assembly and sale of centrifugal ethanol-based extraction systems. The results of Delta Separations 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 preliminary purchase consideration for the acquisition of Delta Separations was $47.2 million, which includes a working capital adjustment and certain other adjustments provided for in the asset purchase agreement expected to be remitted in the next three to six months, at which time a final purchase price will be determined.

The purchase price for the acquisition of the assets was preliminarily allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and approximated $39.3 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 presence in the extraction processing markets.

The purchase price for the acquisition was preliminarily allocated to the assets acquired and liabilities assumed based upon their respective estimated fair values and the remaining consideration was recorded to goodwill. Goodwill of approximately $13.3 million was recorded, 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 commercial greenhouse markets.

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

Cash	$	58
Working capital	(16,464		)
Property, plant and equipment	1,029

On August 30, 2019, the Company acquired all of the outstanding membership interests of Apeks LLC ("Apeks"), a designer and manufacturer of botanical oil extraction systems and equipment. The results of Apeks 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 Apeks was $12.6 million, which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement.

The purchase price for the acquisition was preliminarily allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and approximated $5.9 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 presence in the extraction processing markets.

The preliminary 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	$	4,154
Working capital	(1,412		)
Property, plant and equipment	1,059
Acquired intangible assets	3,400
Other assets	508
Other liabilities	(1,081		)
Goodwill	5,933
Fair value of purchase consideration	$	12,561

	Fair Value		Weighted-Average Amortization Period
Trademarks	$	1,900	5 years
Technology	900		7 years
Customer relationships	600		6 years
Total	$	3,400

In determining the allocation of the purchase price to the assets acquired and the liabilities assumed, the Company uses all available information to make fair value determinations using Level 3 unobservable inputs in which little or no market data exists, and therefore, engages independent valuation specialists to assist in the fair value determination of the acquired long-lived assets.

The acquisitions of Delta Separations, Thermo Energy Systems and Apeks were funded from available cash on hand.

The Company incurred certain acquisition-related costs composed of legal and consulting fees. These costs were recognized as a component of selling, general, and administrative expenses in the consolidated statement of operations.

During the three months ended March 31, 2020, the Company incurred $1.3 million of acquisition-related costs. The Company did not incur any acquisition-related costs during the three months ended March 31, 2019.

Equity-Based Compensation

Share-based Payment Arrangement, Noncash Expense [Abstract]

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 three months ended March 31, which will convert to shares upon vesting, along with the weighted average grant date fair values:

	2020			2019
Awards	Number of Awards (1)	Weighted Average Grant Date Fair Value		Number of Awards (2)	Weighted Average Grant Date Fair Value
Performance stock units	123,870	$	53.29	145,420	$	40.55
Restricted stock units	42,101	$	52.31	117,821	$	39.37

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance or market conditions. The number of shares to be issued may vary between 0% and 200% of the number of performance stock units granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on either the Company’s return on invested capital (“ROIC”) over a one-year period performance period or revenue, gross profit and operating profit thresholds over a two or three-year performance period. The Company's PSUs with a market condition are based on the ranking of the Company’s total shareholder return (“TSR”) performance, on a percentile basis, over a three year performance period compared to the S&P Small Cap Industrial sector, over the same three year performance period.

(2) Performance stock units granted in 2019 have converted to 168,688 shares to be issued to recipients in the first quarter of 2022, representing 116% of the targeted 2019 award, based on the Company’s actual ROIC compared to ROIC target for the performance period ended December 31, 2019.

Equity Based Awards - Settled in Cash

The Company's equity-based liability includes awards under a management stock purchase plan. As of March 31, 2020, the Company's total share-based liabilities recorded on the consolidated balance sheet were $28.7 million, of which $12.2 million was included in non-current liabilities. The share-based liabilities as of December 31, 2019 were $28.0 million, of which $13.2 million was included in non-current liabilities.

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 three months ended March 31,:

Recent Accounting Pronouncements 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 standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the modified retrospective approach through a cumulative-effect adjustment to retained earnings of $291,000, net of $96,000 of income taxes, on the opening consolidated balance sheet as of January 1, 2020. The Company's financial assets that are in the scope of the standard are contract assets and accounts receivables which are short-term in nature. Additionally, the Company has identified and implemented appropriate changes to the Company's business processes, policies and internal controls to support reporting and disclosures. Date of adoption: Q1 2020
ASU 2018-15 Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	The amendments in this update require an entity to apply the same requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract as the entity would for implementation costs incurred to develop or obtain internal-use software. The accounting for the service element is not affected by the amendments in this update.	The standard is effective for the Company as of January 1, 2020. The Company adopted the amendments in this update using the prospective method of adoption, and the adoption did not have a material impact to the Company's financial statements.

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, in the sale and exiting of less profitable businesses or products lines, and the reduction in our manufacturing footprint.

Exit activity costs were incurred during the three months ended March 31, 2020 and 2019 which related to moving and closing costs, contract terminations, and severance incurred as a result of process simplification initiatives. No facilities were closed as a result of these initiatives during these respective periods.

The Company conducts its annual goodwill impairment test as of October 31 each year. All of the Company’s ten reporting units had fair values exceeding their carrying values as of October 31, 2019. In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. The Company considered the current and future macroeconomic and market conditions, along with its current market capitalization, projected cash flows and internal and external forecasts, and projections relating to the impact of the COVID-19 pandemic on each of its reporting units. The Company determined that a triggering event has not occurred which would require an interim impairment test to be performed.

Accounts receivable	$	172,452		$	147,515

Refer to Note 4 "Revenue" concerning the Company's costs in excess of billings.

The Company is exposed to credit losses through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable and costs in excess of billings (collectively "accounts receivable") is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers' accounts receivables. Due to the short-term nature of such accounts receivable, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. Additionally, specific allowance amounts are established to record the appropriate provision for customers that no longer share risk characteristics similar with other accounts receivable. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company considered the current and expected future economic and market conditions surrounding the coronavirus ("COVID-19") pandemic and determined that the estimate of credit losses was not significantly impacted as of March 31, 2020.

Estimates are used to determine the allowance. It is based on assessment of anticipated payment and all other historical, current and future information that is reasonably available.

The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected.
