(the "Company") 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 any subsequent interim period or 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.~~2020.

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.

~~The Company is currently evaluating the requirements of this standard.~~ The standard is effective for the Company as of January 1, 2021.

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, for the three month period ended March 31, 2021, that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected.

The preliminary purchase consideration for the acquisition of TerraSmart was $223.7 million, which includes a preliminary working capital adjustment and certain other adjustments provided for in the stock purchase agreement.

The purchase price for the TerraSmart acquisition was preliminarily allocated to the assets acquired and liabilities assumed based upon their respective fair values estimated as of the date of acquisition. The Company has commenced the process to confirm the existence, condition and completeness of the assets acquired and liabilities assumed to establish fair values of such acquired assets and assumed liabilities and to determine the amount of goodwill to be recognized as of the date of acquisition. Due to the timing of the acquisition, we continue to gather information supporting the acquired assets and assumed liabilities. Accordingly, all amounts recorded are provisional. These provisional amounts are subject to change if new information is obtained concerning facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. The final determination of the fair value of certain assets and liabilities will be completed within a measurement period of up to one year from the date of acquisition. The final values may also result in changes to depreciation and amortization expense related to certain assets such as property, plant and equipment and acquired intangible assets. The preliminary excess consideration was recorded as goodwill and approximated $153.7 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 domestic solar energy market. The final purchase price allocation will be completed no later than December 31, 2021.

Business Strategy

~~Gibraltar’s~~The Company's mission is to create compounding and sustainable value for our stockholders and other stakeholders with strong and relevantleadership 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 Chairmarkets focused on addressing some of the ~~Board through his planned retirement in March 2020. Under Mr. Bosway’s leadership, management completed a thorough evaluation~~world's most challenging opportunities. The foundation of the ~~markets the Company participates in, as well as its position in each market. This work solidified the Company’s~~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~~is built on three core ~~tenets:~~pillars: Business ~~Systems,~~System, Portfolio Management, and ~~Organizational~~Organization 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.

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.

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,~~1.Business System reflects the ~~Company:~~

~~Implemented new~~necessary systems, processes, and management tools required to ~~complement~~deliver consistent and continuous performance improvement, every day. Our Business System is a critical enabler to grow, scale, and deliver our ~~core 80/20 toolkit~~plans. Our Business System is focused on deploying effective tools to drive growth, improve operating performance, and ~~drive improvements~~develop the organization. Our Business System challenges existing paradigms, drives day-to-day performance, forces prioritization of resources, challenges our business models, and brings focus to new product and services development and innovation.

2.Portfolio Management is focused on optimizing the Company’s business portfolio and ensures our financial capital and human resources are effectively and efficiently deployed to deliver sustainable, profitable growth while increasing our relevance with customers and shaping our markets. For a description of recent portfolio management activities, see the actions described below in the Recent Developments section.

3.Organization Development drives the Company’s continuous focus on strengthening and scaling the organization to execute the Company’s plans and meet commitments. The Company aspires to make our ~~operating margins;~~

~~Table~~place of ~~Contents~~

~~Increased~~work the ~~percentage of~~"Best Place to Work", where we focus on creating an environment for our ~~sales that are direct to end customers, allowing us~~people to have ~~a more meaningful connection with~~the best opportunity for success, continue to develop, grow, and learn. At core of this pillar is the Company’s development process focused on helping employees reach their potential, improve performance, develop career roadmaps, identify ongoing education requirements, and respective succession plans. We believe doing so helps us attract and retain the best people so we can execute our ~~end customers, providing the opportunity to better understand the challenges our customers face, and developing solutions to these challenges; and~~business plans.

~~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 COVID-19 and the ~~outbreak of COVID-19.~~challenges noted above. 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 has 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~~stockholder returns.

The $21.6 million, or 10.0% increase, in organic growth during the current year quarter was primarily the result of increased volume in both our Residential and ~~the prior year acquisition of Apeks.

participation gains across that offset challenges from inclement weather, supply chain dynamics. Sales from the prior year acquisition of Architectural Mailboxes also contributed $8.7 million to the increase in the current year quarter.

Net sales in our Agtech segment decreased 5.1%, or $2.5 million, to $46.7 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~~2021 compared to ~~homeowners.~~

~~Net sales in our Industrial and Infrastructure Products segment decreased 9.7%, or $5.3 million, to $49.5~~$49.2 million for the three months ended March 31, 2020. Organic revenue decreased $7.1 million, impacted by the pandemic, inclement weather, supply chain dynamics, along with slower but improving market conditions for greenhouse structure and processing extraction equipment serving the cannabis and hemp markets. Partially offsetting these impacts was continued growth and momentum in the produce market. Sales generated from Thermo and Delta Separations acquired in the first quarter of 2020, ~~compared~~contributed $4.6 million, partially offsetting the decrease in this segment. While backlog decreased 12% year over year, due to ~~$54.9~~the 2020 slowdown in the cannabis and hemp markets, which are improving but not fully recovered, sequentially, backlog increased 5% due primarily to strength in the produce business offsetting the impact of the slower demand in the cannabis and hemp markets.

Net sales in our Infrastructure segment decreased 2.6%, or $0.4 million, to $15.1 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~~2021 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~~$15.5 million for the three months ended March 31, ~~2020~~2020. While revenue was down modestly driven by delays in customer delivery schedules related to the timing of state and federal funding, backlog remained strong increasing 15% compared to the prior year quarter.

Our consolidated gross margin decreased to 20.9% for the three months ended March 31, 2021 compared to 23.1% for the three months ended March 31, 2020. This decrease was partly the result of costs incurred during the current year quarter related to the planned discontinuation of our organic solar tracker solution as we migrate towards the solution offered by our recently acquired TerraSmart business. Additionally, lower gross margins generated from ~~$33.3~~our recent acquisitions contributed to the decline as we continue to integrate them operationally. Partially offsetting the decrease was improved operating execution in all our core businesses compared to the prior year quarter.

Selling, general, and administrative ("SG&A") expenses increased by $10.1 million, or 27.3%, to $47.2 million for the three months ended March 31, ~~2019.~~2021 from $37.1 million for the three months ended March 31, 2020. The ~~$7.9~~$10.1 million increase was ~~largely the result of $3.7~~primarily due to $5.5 million of incremental SG&A expenses recorded quarter over quarter for our recent acquisitions and transaction costs to complete those acquisitions, along with ~~costs incurred~~$3.3 million of higher performance-based compensation expenses as compared to ~~effect~~ the ~~acquisitions closed during~~prior year quarter. Despite the ~~quarter.~~above increases, SG&A expenses as a percentage of net sales ~~increased~~decreased to ~~16.5%~~16.4% for the three months ended March 31, ~~2020~~2021 compared to ~~14.7%~~17.2% for the three months ended March 31, ~~2019.~~2020.

The ~~Renewable Energy and Conservation~~Renewables segment generated an operating margin of ~~5.9%~~(0.6)% in the current year quarter compared to ~~2.4%~~9.2% in the prior year quarter. The decrease in operating margin was the combined result of costs incurred during the current year quarter related to the discontinuation of our organic solar tracker solution along with expected lower margins generated by our recent acquisitions, the result of backlog amortization and integration costs, as we continue to integrate them operationally. Partially offsetting the lower margin is improvement in our core business resulting from continued strong execution in our manufacturing facilities and field operations and diligent price to cost management initiatives. Our acquisition integration plans remain on schedule and we expect to see margins expand during 2021.

The Residential segment generated an operating margin of 16.4% in the current year quarter compared to 13.3% in the prior year quarter. The increase in operating margin was ~~largely~~ the result of ~~$3.4 million~~volume leverage, solid management of ~~incremental~~price to input costs, and continued benefits from 80/20 simplification initiatives offsetting higher costs for materials, labor and logistics management challenges incurred during the ~~prior~~current 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.quarter.

We have completed the bulk of those lower margin projects that we acquired, substantially completed the integration of the processing businesses, and expect to see margins expand throughout the course of 2021.

which $58.0 million was outstanding as of March 31, 2021. Interest ~~income realized~~expense incurred 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.~~2020.

We recognized a provision for income taxes of ~~$3.0~~$1.6 million and ~~$1.6~~$2.3 million, with an effective tax ~~rate~~rates of ~~19.8% for both the three months ended March 31, 2020,~~12.9% and ~~2019, respectively.

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.~~

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. 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 business. The following table sets forth our liquidity position as of:

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. We believe our liquidity, together with the cash expected to be generated from operations, should be sufficient to fund working capital needs and growth initiatives.

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,~~2021, our foreign subsidiaries held ~~$29.6~~$15.2 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.dollars.

~~We are taking advantage of the option~~During 2020, we opted 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~~which allowed us to retain ~~approximately $4~~$4.4 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~~stockholder value.

These expectations are forward-looking statements based upon currently available plans and 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 or expected levels, or sources of financing are not available or not available at acceptable terms, our future liquidity may be adversely affected.
