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, 2018.2019.

The balance sheet at December 31, 20182019 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.

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.

Refer to Note 4 of the Company's consolidated financial statements included in this quarterly report on Form 10-Q for additional information"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.

(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 September 30, 2019 and December 31, 2018. As of September 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 September 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.

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 ablesubject to accommodate our capacity needschanges in economic conditions that are influenced by various factors that could cause actual results to meetdiffer materially from current levels of demand throughout North America and, to a lesser extent, Asia.expectations. Such factors include, but are not limited to:
Business Strategy
Our business strategy focuses on accelerating the growth and financial returnsimpacts of the Company. We strive to deliver best-in-class, sustainable value creation forrecent outbreak of the COVID-19 pandemic on the global economy, our shareholders, customers, suppliers, employees, operations, business, liquidity and team members,cash flows;
general economic conditions and we believe this can be achieved from a transformational changeconditions in the Company’s portfolioparticular markets in which we operate;
changes in customer demand for residential construction, repair and strong operating performance. Our business strategy has four key elements, or "pillars," which are: operational excellence, innovation, portfolio management,remodeling, non-residential construction and acquisitions as a strategic accelerator.

Operational excellence is our first pillar in this strategy. We focus on reducing complexity, adjusting costsinfrastructure projects, botanical extraction equipment, 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.

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 fourth pillarimpact 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 acquisitions.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;

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 targeted four key marketsand expect to continue to examine the need for restructuring of our operations, including consolidation of facilities, reducing overhead costs, curtailing investments in whichinventory, and managing our business 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.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 markets also offer the opportunity for higher returns oninitiatives to pay down debt, improve our investments than those we have generatedliquidity position, and invest 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, Inc. ("Package Concierge") in February 2017, SolarBOS in August 2018, and most recently, Apeks in August 2019, 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.

initiatives. Overall, we believe our business strategy has enabled uscontinue to strive 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.

Consolidated net sales increased by $27.8 million, or 3.7%, to $789.3 million for the nine months ended September 30, 2019 compared to the nine months ended September 30, 2018. The 3.7% increase was the result of a 2.5% increase in pricing to customers, partially offset by a 0.6% decrease in volume. Strong organic growth in our Renewable Energy and Conservation segment along with $13.0 million of sales generated from both the current year acquisition of Apeks and the prior year acquisition of SolarBOS, more than offset the volume decline in our Industrial and Infrastructure segment.

Net sales in our Renewable Energy and Conservation segment increased 14.1%, or $32.4 million, to $261.6 million for the nine months ended September 30, 2019 compared to $229.2 million for the nine months ended September 30, 2018. The increase was led by strong organic growth resulting from our continued efforts to be more relevant to our customers as evidenced by our 72% improvement in backlog year over year in our conservation and renewable energy business. Additionally, incremental sales of $13.0 million combined from the current year acquisition of Apeks and the 2018 acquisition of SolarBOS contributed to the increase.

Net sales in our Residential Products segment of $360.4 million for the nine months ended September 30, 2019 were essentially flat as compared to $360.9 million for the nine months ended September 30, 2018. Slight decreases in volume were nearly offset by increases in carryover pricing to customers implemented in 2018.

Net sales in our Industrial and Infrastructure Products segment decreased 2.4%, or $4.1 million, to $167.3 million for the nine months ended September 30, 2019 compared to $171.4 million for the nine months ended September 30, 2018. Increased volume in the Infrastructure business was more than offset by lower revenues in our Industrial businesses, driven by lower steel prices impacting its core industrial products.
Our consolidated gross margin decreased to 23.3% for the nine months ended September 30, 2019 compared to 24.8% for the nine months ended September 30, 2018. This decrease was the result of incremental costs incurred for field improvements for our tracker solution largely offset by improved operating execution, including benefits from our 80/20 simplification initiatives and a favorable alignment of material costs to customer selling prices.
Selling, general, and administrative (SG&A) expenses increased by $1.9 million, or 1.6%, to $115.4 million for the nine months ended September 30, 2019 from $113.6 million for the nine months ended September 30, 2018. The $1.9 million increase was primarily due to a $6.0 million increase in senior leadership transition costs, $4.1 million of incremental SG&A expenses recorded year over year for our recent acquisitions, along with a $3.4 million increase in exit activity costs related to our simplification initiatives. These increases were partially offset by $10.5 million of lower performance-based compensation expenses, as compared to the prior year. SG&A expenses as a percentage of net sales decreased to 14.6% in the nine months ended September 30, 2019 compared to 14.9% in the nine months ended September 30, 2018.

The Renewable Energy and Conservation segment generated an operating margin of 11.8% during the first nine months of the current year compared to 12.5% in the same period of the prior year. The decrease in operating margin was the result of additional costs related to the field improvements for our solar tracker solution largely offset by the benefits of volume leverage, favorable alignment of material costs to customer selling prices and higher margin product mix.

Our Residential Products segment generated an operating margin of 13.8% during the nine months ended September 30, 2019 compared to 16.0% during the nine months ended September 30, 2018. The decrease in operating margin was due to increased exit activity costs, an unfavorable alignment of material costs to customer selling prices and unfavorable product mix, partially offset by benefits from 80/20 simplification initiatives.
Our Industrial and Infrastructure Products segment generated an operating margin of 8.2% during the nine months ended September 30, 2019 compared to 7.1% during the nine months ended September 30, 2018. The increase in operating margin was the result of a more favorable mix of higher margin products and operational efficiencies resulting from the Company's 80/20 initiatives.

Unallocated corporate expenses increased $3.0 million from $22.8 million during the nine months ended September 30, 2018 to $25.9 million during the nine months ended September 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.

The Company recorded other expense of $0.7 million for the nine months ended September 30, 2019 and other income of $0.1 million for the nine months ended September 30, 2018. The increase in other expense from the prior year was primarily the result of foreign currency fluctuations.

Interest expense decreased by $7.0 million to $2.3 million for the nine months ended September 30, 2019 compared to $9.3 million for the nine months ended September 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 nine months ended September 30, 2019 and 2018, no amounts were outstanding under our then applicable revolving credit facility.

The effective tax rate for the nine months ended September 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 nine months ended September 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 $2.6 million tax benefit related to performance share unit vesting.differences.

Outlook

We expectGibraltar 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 profitableto 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 finalfirst 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 baseduntil consumer confidence and spending improves. We have not seen a disruption from our suppliers.

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 opportunitiesThe following table sets forth our liquidity position as appropriate while focusing on working capital efficiency and profit improvement opportunities to minimize the cash invested to operate our businesses.of:

As of September 30, 2019, our liquidity of $531.6 million consisted of $137.6 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 $535.9 million as of September 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 leveragecash on hand, lack of outstanding debt, and increasedavailable borrowing capacity along with enhanced flexibility in our newprovided under the Senior Credit Agreement provide us with ample liquidity.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 believe our liquidity, togetherremain in contact with the cash expectedcompanies aligned with our strategic initiatives and expect to be generated from operations, should be sufficient to fundre-engage in these acquisition processes when the economic impact becomes clearer. In the interim, we remain highly focused on managing our working capital, needswhich may include adjusting scheduled deliveries of inventory to match current demand levels, closely monitoring customer credit and simplification initiatives. We continuecollection activities, and working to search for strategic acquisitions. Larger acquisitions may require additional borrowings and/or the issuance of our common stock or other securities.extend payment terms.

Our Senior Credit Agreement provides us with 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 September 30, 2019,March 31, 2020, our foreign subsidiaries held $27.3$29.6 million of cash in U.S. dollars, of which $13.8$12.9 million is available to be repatriated to the U.S. tax-free., 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. AnyAll 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 the improvement ofsustainable shareholder value. Our acquisition of Apeks during this quarter and our 2018 acquisition of SolarBOS were 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.

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, 2018.2019. 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.
