(5) ACQUISITION
On July 5, 2023, the Company acquired the assets of a privately held Utah-based company that manufactures and distributes roof flashing and accessory products, and sells direct to roofing wholesalers. The results of this company have been included in the Company's consolidated financial results since the date of acquisition within the Company's Residential segment. The purchase consideration for this acquisition was $10.4 million, which includes a working capital adjustment and certain other adjustments provided for in the asset purchase agreement.
The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values estimated as of the date of acquisition. The Company has completed the process to confirm the existence, condition, and completeness of the assets acquired and liabilities assumed to establish fair value of such assets and liabilities and to determine the amount of goodwill to be recognized as of the date of acquisition. The excess consideration was recorded as goodwill and approximated $3.0 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 building products markets.
The 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):

Working capital | $ | 827 |
Property, plant and equipment | 195 |
Acquired intangible assets | 6,310 |
Other assets | 134 |
Other liabilities | (72) |
Goodwill | 3,023 |
Fair value of purchase consideration | $ | 10,417 |

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

Trademarks | $ | 250 |  |  | 3 years
Customer relationships | 6,060 |  |  | 12 years
Total | $ | 6,310 |  |  |

In determining the allocation of the purchase price to the assets acquired and 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 acquisition of the privately held Utah-based company was financed primarily through borrowings under the Company's revolving credit facility.

Revolving Credit Facility
On December 8, 2022, the Company entered into a Credit Agreement (the "Credit Agreement") which provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million. The Company can request additional financing to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Credit Agreement. The Credit Agreement contains two financial covenants. As of March 31, 2024, the Company was in compliance with all financial covenants. The Credit Agreement terminates on December 8, 2027.
Borrowings under the Credit Agreement bear interest, at the Company’s option, at a rate equal to the applicable margin plus (a) a base rate, (b) a daily simple secured overnight financing rate ("SOFR") rate, (c) a term SOFR rate or (d) for certain foreign currencies, a foreign currency rate, in each case subject to a 0% floor. Through March 31, 2023, the Credit Agreement had an initial applicable margin of 0.125% for base rate loans and 1.125% for SOFR and alternative currency loans. Thereafter, the applicable margin ranges from 0.125% to 1.00% for base rate loans and from 1.125% to 2.00% for SOFR and alternative currency loans based on the Company’s Total Net Leverage Ratio, as defined in the Credit Agreement. In addition, the Credit Agreement is subject to an annual commitment fee, payable quarterly, which was initially 0.20% of the daily average undrawn balance of the revolving credit facility and, from and after April 1, 2023, ranges between 0.20% and 0.25% of the daily average undrawn balance of the revolving credit facility based on the Company’s Total Net Leverage Ratio.
Borrowings under the Credit Agreement are secured by the trade receivables, inventory, personal property, equipment, and general intangibles of the Company’s significant domestic subsidiaries. Capital distributions are subject to certain Total Net Leverage Ratio requirements and capped by an annual aggregate limit under the Credit Agreement.
Standby letters of credit of $3.7 million have been issued under the Credit Agreement to third parties on behalf of the Company as of March 31, 2024. These letters of credit reduce the amount otherwise available under the revolving credit facility. The Company had $396.3 million and $396.1 million of availability under the revolving credit facility as of March 31, 2024 and December 31, 2023, respectively.
(8) EQUITY-BASED COMPENSATION

Amended and Restated 2018 Equity Incentive Plan (the "Amended 2018 Plan") which includes a total of 1,631,707 shares available for issuance.

The Gibraltar Industries, Inc. Amended and Restated 2016 Stock Plan for Non-Employee Directors ("Non-Employee Directors Plan") which includes 200,000 shares available for issuance, allows the Company to grant awards of shares of the Company's common stock to current 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 provides the number of stock units granted during the three months ended March 31, along with the weighted-average grant-date fair value of each award:

|  | 2024 |  | 2023
Awards |  | Number of Awards |  | Weighted- Average Grant-Date Fair Value |  | Number of Awards (2) |  | Weighted- Average Grant-Date Fair Value
Performance stock units (1) |  | 58,582 |  |  | $ | 77.70 |  |  | 81,611 |  |  | $ | 53.44 |
Restricted stock units |  | 29,671 |  |  | $ | 77.70 |  |  | 46,646 |  |  | $ | 53.44 |

(1) The Company’s performance stock units (“PSUs”) represent shares granted for which the final number of shares earned depends on financial performance. The number of shares to be issued may vary between 0% and 200% of the number of PSUs granted depending on the relative achievement to targeted thresholds. The Company's PSUs with a financial performance condition are based on the Company’s return on invested capital (“ROIC”) over a one-year performance period.
(2) PSUs granted in the first quarter of 2023 includes 7,825 units that were forfeited in the third quarter of 2023 and 147,572 units that will be converted to shares and issued to recipients in the first quarter of 2026, representing 200.0% of the target amount granted and not subsequently forfeited, based on the Company's actual ROIC compared to ROIC target for the performance period ended December 31, 2023.
Equity-Based Awards - Settled in Cash
The Company's equity-based awards that are settled in cash are the awards under the Management Stock Purchase Plan (the “MSPP”) which is authorized under the Company's equity incentive plans. The 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 deferred compensation.
The deferrals and related company match are credited to an account that contains 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’s 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.
Total MSPP liabilities recorded on the consolidated balance sheet as of March 31, 2024 were $23.0 million, of which $2.6 million was included in current accrued expenses and $20.4 million was included in non-current liabilities. Total MSPP liabilities recorded on the consolidated balance sheet as of December 31, 2023 were $20.0 million, of which $2.0 million was included in current accrued expenses and $18.0 million was included in non-current liabilities. The value of the restricted stock units within the MSPP liabilities was $20.0 million and $17.3 million at March 31, 2024 and December 31, 2023, respectively.
The following table provides the number of restricted stock units credited to active participant accounts and the payments made with respect to MSPP liabilities during the three months ended March 31,:

(10) 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, the sale and exiting of less profitable businesses or product lines, and a reduction in the Company's manufacturing footprint.
As a result of process simplification initiatives, the Company has incurred exit activity costs related to moving and closing costs and severance, along with asset impairment recoveries related to the write-down of inventory and other charges associated with discontinued product lines. Additionally, the Company has incurred the aforementioned costs resulting from the sale and/or closure of facilities including costs recorded during the three months ended March 31, 2023.

Recent Trends
The effect on the Company's customers in the Renewables business due to the trade related disruption in the supply of solar modules from the impacts of the Uyghur Forced Labor Prevention Act ("UFLPA") and the Department of Commerce's ("USDOC") anti-dumping and countervailing duties ("AD/CVD") investigation, both initiated in 2022, continues to diminish. These customers have continued to adapt to the ongoing disruption in this space and have identified alternative sources for modules not impacted by these regulatory items that require either traceability of components imported and/or potentially impose tariffs on the modules. However, some of these customers continue to pause on executing new renewable energy projects while they are awaiting final guidance from the Department of Treasury relative to rules under the Inflation Reduction Act (IRA) in order to maximize tax incentives. Furthermore, a continued challenge to manage project specific permitting delays from relevant government entities to build new solar fields has also affected the execution of new renewable energy projects. The Company believes that these dynamics will continue throughout 2024.
On April 24, 2024, a new petition was filed with the USDOC claiming potentially illegal trade practices with Cambodia, Malaysia, Thailand and Vietnam, the same four countries named in the 2022 AD/CVD case. The USDOC has 20 days to determine whether to initiate an investigation on the matter.
Business Strategy
The Company's mission is to make life better for people and the planet, fueled by advancing the disciplines of engineering, science, and technology. The Company is innovating to reshape critical markets in sustainable power, comfortable and efficient living, and productive growing throughout North America. Furthermore, the Company strives to create compounding and sustainable value for its stockholders and stakeholders with strong and relevant leadership positions in higher growth, profitable end markets focused on addressing some of the world's most challenging opportunities. The foundation of the Company's strategy is built on three core pillars: Business System, Portfolio Management, and Organization Development.
1.Business System reflects the necessary systems, processes, and management tools required to deliver consistent and continuous performance improvement, every day. The Company's business system is a critical enabler to grow, scale, and deliver its plans. The Company's focus is on deploying effective tools to drive growth, improve operating performance, and develop the organization utilizing 80/20 and lean quote-to-cash initiatives along with digital systems for speed, agility and responsiveness. The Business System pillar challenges existing operating paradigms, drives day-to-day performance, forces prioritization of resources, tests the Company's business models, and drives new product and services innovation.
2.Portfolio Management is focused on optimizing the Company’s business portfolio in higher growth markets with leadership positions while ensuring its financial capital and human resources are effectively and efficiently deployed to deliver sustainable, profitable growth while increasing its relevance with customers and shaping its markets. In 2023, the Company acquired the assets of a privately held Utah-based company in the Residential segment and sold its Japan-based solar racking business within the Renewables segment to help achieve these objectives.
3.Organization Development drives the Company’s continuous focus on ensuring it has the right design and structure to scale the organization in order to execute the Company’s plans and meet commitments. The Company's focus is on creating an environment for our people to have 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. The Company believes doing so helps it attract and retain the best people to execute its business plans.
The Company believes the key elements of the Company's strategy enable the Company to respond timely to changes in the end markets the Company serves, including the broader market dynamics experienced over the past few years. The Company continues to examine the need for restructuring of the Company's operations, including consolidation of facilities, reducing overhead costs, curtailing investments in working capital, and managing the Company's business to generate incremental cash. The Company believes its strategy enables the Company to respond to volatility in commodity and other input costs and fluctuations in customer demand, along with striving to maintain and improve margins. The Company has used cash flows generated by these initiatives to improve the Company's liquidity position, invest in growth initiatives and return capital to the Company's shareholders through share repurchases. Overall, the Company continues to strive to achieve stronger financial results, make more efficient use of capital, and deliver higher stockholder returns.

Consolidated net sales were essentially flat for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, the net result of a slight increase in pricing to customers offset by a decrease due to portfolio management activities in the prior year. Growth in the Company's Residential and Infrastructure segments, along with revenue of $1.3 million generated from a recent acquisition, was more than offset by $4.5 million of sales related to portfolio management along with an anticipated decline in revenue in the Company's Renewables segment. Consolidated backlog decreased 3% to $340 million, as compared to the end of the prior year quarter.
Net sales in the Company's Renewables segment decreased $7.7 million, or 13.0%, to $51.5 million for the three months ended March 31, 2024 compared to $59.2 million for the three months ended March 31, 2023. Revenue declined due to the rapid customer transition to a recently launched tracker product, which currently has a longer supply lead time than fixed tilt products which largely comprised the demand for prior year quarter's orders and revenues. Portfolio management activities related to the sale of the segment's Japan renewables business in December 2023 also contributed to the decline. Backlog increased 8% from the prior year, on pace with expectations, as end market demand remains robust even as customers await final domestic content tax credit guidance related to the Inflation Reduction Act and navigate project-specific permitting delays.

Net sales in the Company's Residential segment increased $5.6 million, or 3.1%, to $185.1 million for the three months ended March 31, 2024 compared to $179.5 million for the three months ended March 31, 2023. Organic growth of 2.4% was driven by continuing participation gains, growth with customers and geographic expansion. In addition, $1.3 million of revenue was generated by the recent acquisition.
Net sales in the Company's Agtech segment decreased 5.3%, or $1.8 million, to $34.0 million for the three months ended March 31, 2024 compared to $35.9 million for the three months ended March 31, 2023. The revenue declined due to $2.5 million of revenues recorded in the prior year related to portfolio management actions which were partially offset by a slight increase in volume. While backlog decreased 21% year over year due to timing of order flow, subsequent project bookings in April will contribute to backlog and revenue in the coming months.
Net sales in the Company's Infrastructure segment increased 17.1%, or $3.2 million, to $21.9 million for the three months ended March 31, 2024 compared to $18.7 million for the three months ended March 31, 2023. The increase in revenue was due to strong execution, continued solid end market demand and market participation gains. Backlog decreased 10% as expected from the prior year due to the continued progress on a large project, while demand, project design and quoting remain strong.
The Company's consolidated gross margin increased to 28.9% for the three months ended March 31, 2024 compared to 26.2% for the three months ended March 31, 2023. The increase was driven by improved price to material cost alignment, and continued operational efficiencies, along with 80/20 initiatives and favorable business and product mix.
Selling, general, and administrative ("SG&A") expenses increased by $5.1 million, or 10.7% to $52.7 million for the three months ended March 31, 2024 compared to $47.6 million for the three months ended March 31, 2023. The $5.1 million increase was primarily due to higher performance-based compensation expense as compared to the prior year quarter. SG&A expenses as a percentage of net sales increased to 18.1% for the three months ended March 31, 2024 compared to 16.2% for the three months ended March 31, 2023.
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):

The Renewables segment generated an operating margin of 3.2% in the current year quarter compared to 3.8% in the prior year quarter. The decrease in operating margin was a result of lower volumes and product line mix associated with the ramp up of the new tracker product line in the current year quarter.
The Residential segment generated an operating margin of 18.6% in the current year quarter compared to 16.4% in the prior year quarter. Operating margin improved year over year, driven by continued improvement in execution and ongoing improvement in price/cost management.
The Agtech segment generated an operating margin of 7.7% in the current year quarter compared to 6.5% in the prior year quarter. Operating margin improved year over year due to the impact of restructuring costs incurred in the prior year partially offset by project start date delays and market and product mix across the segment.
The Infrastructure segment generated an operating margin of 22.4% during the three months ended March 31, 2024 compared to 14.5% during the three months ended March 31, 2023. The margin improved year over year driven by increased volume, favorable price/cost alignment, ongoing strong operating execution, 80/20 productivity, and improving product mix.

Expense in the prior year quarter was the result of a $49.9 million outstanding balance on the Company's revolving credit facility as of March 31, 2023, while no amounts were outstanding during the three months ended March 31, 2024.
Other income increased year over year with $1.0 million recorded for the three months ended March 31, 2024, compared to $0.4 million recorded for the three months ended March 31, 2023. The change year over year is the combined result of $1.0 million of working capital and other adjustments recorded in the current year quarter, relating to the sale of the Company's Japan-based solar racking business within its Renewables segment and foreign currency translation fluctuations.
The Company recognized a provision for income taxes of $8.6 million and $7.2 million, with effective tax rates of 25.6% and 25.4% for the three months ended March 31, 2024, and 2023, respectively. The effective tax rate for the three months ended March 31, 2024, and 2023, respectively, was greater than the U.S. federal statutory rate of 21% due to state taxes and nondeductible permanent differences partially offset by favorable discrete items due to an excess tax benefit on stock-based compensation.
Liquidity and Capital Resources
The following table sets forth the Company's liquidity position as of (in thousands):

|  | March 31, 2024 |  | December 31, 2023
Cash and cash equivalents |  | $ | 146,665 |  |  | $ | 99,426 |
Availability on revolving credit facility |  | 396,257 |  |  | 396,056 |
|  | $ | 542,922 |  |  | $ | 495,482 |

Sources of Liquidity
The Company's primary sources of liquidity are comprised of cash on hand and its available borrowing capacity provided under the Company's Credit Agreement (the "Credit Agreement"). The Credit Agreement provides for a revolving credit facility and letters of credit in an aggregate amount equal to $400 million and terminates on December 8, 2027. The Company can request additional financing to increase the revolving credit facility to $700 million or enter into a term loan of up to $300 million subject to conditions set forth in the Credit Agreement. See Note 7 to the Company's consolidated financial statements in Part I, Item 1, Financial Statements, of this Quarterly Report on Form 10-Q for further information on the Credit Agreement.
Generally, the Company's foreign operations have generated cash flow from operations sufficient to invest in working capital and fund their capital improvements. As of March 31, 2024 and December 31, 2023, the Company's foreign subsidiaries held $4.7 million and $6.9 million of cash, respectively.
The Company believes that these sources, together with cash expected to be generated from operations, should provide the Company with ample liquidity and capital resources to meet its cash requirements and to continue to invest in operational excellence, growth initiatives and the development of the organization.
Uses of Cash / Cash Requirements
The Company's material short-term cash requirements primarily include accounts payable, certain employee and retiree benefit-related obligations, operating lease obligations, capital expenditures, and other purchase obligations originating in the normal course of business for inventory purchase orders and contractual service agreements. The Company's principal capital requirements are to fund its operations' working capital and capital improvements, as well as provide capital for acquisitions and to strategically allocate capital through repurchases of Company stock under the Company's current authorized program ending May 2, 2025. The Company 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 its business.
Over the long-term, the Company expects that future investments, including strategic business opportunities such as acquisitions, may be financed through a number of sources, including internally available cash, availability under

the Credit Agreement, new debt financing, the issuance of equity securities, or any combination of the aforementioned.
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, the Company's future liquidity may be adversely affected.
Except as disclosed above, there have been no material changes in the Company's cash requirements since December 31, 2023, the end of fiscal year 2023. See Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

The cash generated from working capital and other net operating assets was largely due to increases in accounts payable, the result of the timing of purchases and vendor payments, partially offset by investment in inventory to align with anticipated seasonal sales volumes increases.
Net cash provided by operating activities for the three months ended March 31, 2023 of $38.0 million consisted of net income of $21.1 million, non-cash net charges totaling $9.3 million, which include depreciation, amortization, stock-based compensation, exit activity recoveries and other non-cash charges, and $7.6 million of cash generated from working capital and other net assets.

(b)Changes in Internal Control over Financial Reporting

Except for the implementation of this ERP system, there have been no changes in the Company’s internal control over financial reporting (as defined by Rule 13a-15(f) or 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
