Organization, Consolidation and Presentation of Financial Statements [Abstract]
Operations and Summary of Significant Accounting Policies	Operations and Summary of Significant Accounting Policies Nature of Operations Simpson Manufacturing Co., Inc., through Simpson Strong-Tie Company Inc. and its other subsidiaries (collectively, the “Company”), focuses on designing, manufacturing, and marketing systems and products to make buildings and structures safe and secure. The Company designs, engineers and is a leading manufacturer of wood construction products, including connectors, truss plates, fastening systems, fasteners and shearwalls, and concrete construction products, including adhesives, specialty chemicals, mechanical anchors, powder actuated tools and fiber reinforcing materials. The Company markets its products to the residential construction, industrial, commercial and infrastructure construction, remodeling and do-it-yourself markets. The Company operates exclusively in the building products industry. The Company’s products are sold primarily in the U.S., Canada, Europe and Pacific Rim. A significant portion of the Company’s business is dependent on economic activity within the North America segment. The Company's business is also dependent on the availability of steel, its primary raw material. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Simpson Manufacturing Co., Inc. and its subsidiaries. Investments in 50.0% or less owned entities are accounted for using either cost or equity method. All significant intercompany transactions have been eliminated. Certain prior years' amounts have been reclassified to conform to the fiscal 2024 presentation. These reclassifications had no impact on the Company's Consolidated Balance Sheets, Consolidated Statements of Operations, Consolidated Statements of Stockholders’ Equity or Consolidated Statements of Cash Flow. Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that these consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation under GAAP. Cash Equivalents The Company classifies investments that are highly liquid and have maturities of three months or less at the date of purchase as cash equivalents. As of December 31, 2024, and 2023, the value of these investments was $49.3 million and $163.6 million, respectively, consisting of money market funds. The value of the investments is based on cost, which approximates fair value based on Level 1 inputs. Current Estimated Credit Loss - Allowance for doubtful accounts The Company maintains an allowance for doubtful accounts receivable for estimated future expected credit losses resulting from customers' failure to make payments on its accounts receivable. The Company determines the estimate of the allowance for doubtful accounts receivable by considering several factors, including (1) specific information on the financial condition and the current creditworthiness of customers, (2) credit rating, (3) payment history and historical experience, (4) aging of the accounts receivable, and (5) reasonable and supportable forecasts about collectability . The Company also reserves 100.0% of the amounts deemed uncollectible due to a customer's deteriorating financial condition or bankruptcy. Every quarter, the Company evaluates the customer group using the accounts receivable aging report and its best judgment when considering changes in customers' credit ratings, level of delinquency, customers' historical payments and loss experience, current market and economic conditions, and expectations of future market and economic conditions. The changes in the allowance for credit losses for the year ended December 31, 2024 are outlined in the table below: Balance Balance (in thousands) December 31, 2023 Expense (Deductions), net Write-Offs 1 December 31, 2024 Allowance for credit losses $ 3,881 $ 115 $ 998 $ 2,998 1 Amount is net of recoveries and the effect of foreign currency fluctuations for the year ended December 31, 2024 Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash in banks, short-term investments in money market funds and trade accounts receivable. The Company maintains its cash on demand deposit and in money market accounts held in 35 banks, and at times these cash and investments may be in excess of amounts insured by the Federal Deposit Insurance Corporation (FDIC). However, we have not experienced any losses on these accounts. Inventory Valuation Inventories are stated at the lower of cost or net realizable value. Cost includes all costs incurred in bringing each product to its present location and condition, as follows: • Raw materials and purchased finished goods for resale — principally valued at a cost determined on a weighted average basis; and • In-process products and finished goods — the cost of direct materials and labor plus attributable overhead based on a normal level of activity. The Company applies net realizable value when making estimates for obsolescence to the gross value of inventory. Estimated net realizable value is based on estimated selling price less further costs expected to be incurred through completion and disposal. The Company impairs slow-moving products by comparing inventories on hand to projected demand. If on-hand supply of a product exceeds projected demand or if the Company believes the product is no longer marketable, the product is considered obsolete inventory. The Company revalues obsolete inventory to its net realizable value and has consistently applied this methodology. When impairments are established, a new cost basis of the inventory is created . An unexpected change in market demand, building codes or buyer preferences could reduce the rate of inventory turnover and require the recognition of more obsolete inventory. Other Current Assets Other current assets consist primarily of prepaid expenses, derivative assets-current, and other miscellaneous assets. Refer to Note 9 for more information for derivative assets-current. The remaining assets are less than 5% of the other current assets. Warranties and Recalls The Company provides product warranties for specific product lines and records estimated expenses in the period in which the recall occurs, none of which has been material to the consolidated financial statements. In a limited number of circumstances, the Company may also agree to indemnify customers against legal claims made against those customers by the end users of the Company’s products. Historically, payments made by the Company, if any, under such agreements have not had a material effect on its consolidated statement of operations, cash flows or financial position. Equity Investments The Company accounts for investments and ownership interests under either cost or the equity method accounting when it has the ability to exercise significant influence but does not have a controlling financial interest. The Company records its interest in the net earnings of its equity method investees, along with adjustments for unrealized profits or losses within earnings or loss from equity interests in the consolidated statement of operations. The investment is reviewed for impairment whenever factors indicate the carrying amount might not be recoverable and the decrease in value, if any, is recognized in the period the impairment occurs in the consolidated statement of operations. Fair Value of Financial Instruments Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unrelated market participants. As such, fair value is a market-based measurement that is determined based on assumptions that unrelated market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified under a three-tier fair valuation hierarchy based on the observability of the inputs available in the market: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying amounts of trade accounts receivable, accounts payable, accrued liabilities and other current liabilities approximate fair value due to the short-term nature of these instruments. The fair values of the Company's investments and liabilities in the deferred compensation plan are classified as Level 1 within the fair value hierarchy, and are subject to investment risks. The fair values of interest rate and foreign currency contracts are classified as Level 2 within the fair value hierarchy. The fair values of the Company’s contingent consideration related to acquisitions is classified as Level 3 within the fair value hierarchy, as these amounts are based on unobservable inputs such as management estimates and entity-specific assumptions and are evaluated on an ongoing basis. The following tables summarize the financial assets and financial liabilities measured at fair value for the Company as of December 31, 2024 and 2023: 2024 2023 (in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Cash equivalents (1) $ 49,273 $ — $ — $ 163,558 $ — $ — Term loan due 2027 (2) — 388,125 — — 410,625 — Revolver due 2027 (2) — — — — 75,038 — Derivative instruments - assets (3) — 32,355 — — 21,835 — Derivative instruments - liabilities (3) — 7,198 — — 30,111 — Investment in deferred compensation plan (4) 944 — — — — — Deferred compensation plan liabilities (4) 1,974 — — — — — Contingent considerations — — 5,400 — — 6,600 (1) The carrying amounts of cash equivalents, representing money market funds traded in an active market with relatively short maturities, are reported on the consolidated balance sheet as of December 31, 2024 and 2023 as a component of "Cash and cash equivalents". (2) The carrying amounts of our term loan and revolver approximate fair value as of December 31, 2024 and 2023 based upon their terms and conditions as disclosed in Note 14 (3) Derivatives for interest rate, foreign exchange, and forward swap contracts are discussed in Note 9 (4) Non-qualified deferred compensation plan. Derivative Instruments The Company uses derivative instruments as a risk management tool to mitigate the potential impact of certain market risks. Foreign currency and interest rate risk are the primary market risks the Company manages through the use of derivative instruments, which are accounted for as cash flow hedges or net investment hedges under the accounting standards and carried at fair value as other current or noncurrent assets or as other current or other long-term liabilities in the consolidated balance sheets. Assets and liabilities with the legal right of offset are not offset in the consolidated balance sheets. Net deferred gains and losses related to changes in fair value of cash flow hedges are included in accumulated other comprehensive income/loss ("OCI"), a component of stockholders' equity in the consolidated balance sheets; and are reclassified into the line item in the consolidated statement of operations in which the hedged items are recorded in the same period the hedged item affects earnings. The effective portion of gains and losses attributable to net investment hedges is recorded net of tax to OCI to offset the change in the carrying value of the net investment being hedged. Recognition in earnings of amounts previously recorded to OCI are limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. Changes in fair value of any derivatives that are determined to be ineffective are immediately reclassified from OCI into earnings. Deferred Compensation Plan The Company established a non-qualified deferred compensation plan ("DCP" or “the Plan”) in April 2023 for eligible employees and members of the Board of Directors. The Plan provides eligible participants the opportunity to defer and invest a specified percentage of their compensation, including the Company stock awards upon vesting. The Plan is a non-qualified plan that is informally funded by assets in a rabbi trust, which restricts the Company's use and access to the assets held but is subject to the claims of the Company's creditors in the event that the Company becomes insolvent. The amount of compensation to be deferred by participants are based on their own elections and are adjusted for any investment changes that the participants direct. This plan does not provide for employer contributions. The Plan permits diversification of vested shares (common stock) into other equity securities subject to a six-month holding period subsequent to vesting. Accounting for deferred common stock will be under either plan C or plan D. Accounting will depend on whether or not the employee has diversified the common stock. Under plan C, diversification is permitted but the employee has not diversified. Under plan D, diversification is permitted and the employee has diversified. For common stock that have not been diversified, the employer stock held in the deferred compensation plan is classified in a manner similar to treasury stock and presented separately on the consolidated balance sheets as the Company's common stock held by the non-qualified deferred compensation plan. Common stock will be recorded at fair value of the stock at the time it vested, subsequent changes in the value of the common stock is not recognized. The deferred compensation obligations are measured independently at fair value of the common stock with a corresponding charge or credit to compensation cost. Fair value is determined as the product of the common stock and the closing price of the stock each reporting period. Under plan D, assets held by the rabbi trust are subject to applicable GAAP. The deferred compensation obligation is measured independently at fair value of the underlying assets. The Company previously presented certain DCP transactions within existing financial statement line items of the consolidated balance sheets and consolidated statement of stockholders’ equity for periods ended December 31, 2023 . For the year ended December 31, 2024, the Company presented t he equity balances related to "Non-qualified deferred compensation plan share awards" as mezzanine equity for $7.8 million and they were combined with stock-based compensation expense in the consolidated statement of stockholders’ equity for the year ended December 31, 2024 . The Company has evaluated the errors both qualitatively and quantitatively and has concluded that they have immaterial impact on the periods presented. Business Combinations and Asset Acquisitions Business combinations are accounted for under the acquisition method in accordance with ASC 805, Business Combinations . The acquisition method requires identifiable assets acquired and liabilities assumed and any noncontrolling interest in the business acquired be recognized and measured at fair value on the acquisition date, which is the date that the acquirer obtains control of the acquired business. The amount by which the fair value of consideration transferred as the purchase price exceeds the net fair value of assets acquired and liabilities assumed is recorded as goodwill. Acquisitions that do not meet the definition of a business under the ASC are accounted for as an acquisition of assets, whereby all of the cost of the individual assets acquired and liabilities assumed, including certain transactions costs, are allocated on a relative fair value basis. Accordingly, goodwill is never recognized in an asset acquisition. Refer to Note 3 Property, Plant and Equipment Property, plant and equipment are carried at cost. Major renewals and betterments are capitalized while maintenance and repairs are expensed as incurred. When assets are sold or retired, their costs and accumulated depreciation are removed from the accounts, and the resulting gains or losses are reflected in the consolidated statements of operations. The ASC 350 Intangibles—Goodwill and Other provides guidance on capitalization of the costs incurred for computer software developed or obtained for internal use. The Company capitalizes qualified external costs and internal costs related to the purchase and implementation of software projects used for business operations and engineering design activities. Capitalized software costs primarily include purchased software, internal costs and external consulting fees. Capitalized software projects are amortized over the estimated useful lives of the software. Depreciation and Amortization Software, including amounts capitalized for internally developed software is amortized on a straight-line basis over an estimated useful life of three three improvements are amortized using the straight-line method over the shorter of the expected life or the remaining term of the lease. Purchased intangible assets with finite useful lives are amortized using the straight-line method over the estimated useful lives of the assets. Preferred Stock The Company’s Board of Directors has the authority to issue authorized and unissued preferred stock in one o r more series with such designations, rights and preferences as may be determined from time to time by the Board of Directors. Accordingly, the Board of Directors is empowered, without stockholder approval, to issue preferred stock with dividend, redemption, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of the Company’s common stock. Common Stock Subject to the rights of holders of any preferred stock that may be issued in the future, holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by the Board of Directors out of legally available funds, and in the event of liquidation, dissolution or winding-up of the Company, to share ratably in all assets available for distribution. The holders of common stock have no preemptive or conversion rights. Subject to the rights of any preferred stock that may be issued in the future, the holders of common stock are entitled to one vote per share on any matter submitted to a vote of the stockholders. A director in an uncontested election is elected if the votes cast “for” such director’s election exceed the votes cast “against” such director’s election, except that, if a stockholder properly nominates a candidate for election to the Board of Directors, the candidates with the highest number of affirmative votes (up to the number of directors to be elected) are elected. There are no redemption or sinking fund provisions applicable to common stock. Comprehensive Income or Loss Comprehensive income is defined as net income plus other comprehensive income or loss. Other comprehensive income or loss consists of changes in cumulative translation adjustments, changes in unamortized pension adjustments and changes in the fair value of derivative instruments classified as cash flow hedge instruments, all of which are recorded directly in accumulated other comprehensive income within stockholders’ equity. Foreign Currency Translation The local currency is the functional currency for all of the Company’s operations in Europe, Canada, Asia, Australia and New Zealand. Assets and liabilities denominated in foreign currencies are translated using the exchange rate on the balance sheet date. Revenues and expenses are translated using average exchange rates prevailing during the year. The translation adjustment resulting from this process is shown separately as a component of stockholders’ equity. Foreign currency transaction gains or losses are presented below operating income. Revenue Recognition Generally, the Company's revenue contract with a customer exists when (1) the goods are shipped, services are rendered, and the related invoice is generated, (2) the duration of the contract does not extend beyond the promised goods or services already transferred and (3) the transaction price of each distinct promised product or service specified in the invoice is based on its relative stated standalone selling price. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer at a point in time. Our shipping terms provide the primary indicator of the transfer of control. The Company's general shipping terms are Incoterm C.P.T. (F.O.B. shipping point), where the title, and risk and rewards of ownership transfer at the point when the products are no longer on the Company's premises. Other Incoterms are allowed as exceptions depending on the product or service being sold and the nature of the sale. The Company recognizes revenue based on the consideration specified in the invoice with a customer, excluding any sales incentives, discounts, and amounts collected on behalf of third parties (i.e., governmental tax authorities). Based on historical experience with the customer, the customer's purchasing pattern, and its significant experience selling products, the Company concluded that a significant reversal in the cumulative amount of revenue recognized would not occur when the uncertainty (if any) is resolved (that is, when the total amount of purchases is known). Contract liability is recorded when consideration is received from a customer and the Company has remaining unsatisfied performance obligations. The Company presents taxes collected and remitted to governmental authorities on a net basis in the consolidated statements of operations. Additionally, all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer (e.g., sales, use, value added, and some excise taxes) are excluded from revenue. Refer to Note 2 Cost of Sales Cost of sales includes material, labor, factory and tooling overhead, shipping, and freight costs. Major components of these expenses are steel and other materials, packaging and cartons, personnel costs, and facility costs, such as rent, depreciation and utilities, related to the production and distribution of the Company’s products. Inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, and other costs of the Company’s distribution network are also included in cost of sales. Tool and Die Costs Tool and die costs are included in product costs in the year incurred. Product and Software Research and Development Costs Product research and development costs, which are included in operating expenses and are charged against income as incurred, were $20.7 million, $24.8 million and $15.7 million in 2024, 2023 and 2022, respectively. Product research and development expenses include all related personnel costs including salary, benefits, retirement, stock-based compensation costs, as well as computer and software costs, professional fees, supplies, tools and maintenance costs. In 2024, 2023 and 2022, the Company incurred software development expenses related to its ongoing expansion into the component manufacturing and residential markets as well as ongoing development of construction-related applications that serve multiple end markets, and some of the software development costs were capitalized that were amortized over the estimated useful lives and reviewed for impairment. The Company amortizes acquired patents over their remaining lives and performs periodic reviews for impairment. The cost of internally developed patents is expensed as incurred. Refer to Note 1 0 Selling Costs Selling costs include expenses associated with selling, merchandising and marketing the Company’s products. Major components of these expenses are personnel, sales commissions, facility costs such as rent, depreciation and utilities, professional services, information technology costs, sales promotion, advertising, literature and trade shows. Advertising Costs Advertising costs are included in selling expenses and were $14.6 million, $12.3 million, and $12.6 million in 2024, 2023, and 2022, respectively. General and Administrative Costs General and administrative costs include personnel, information technology related costs, facility costs such as rent, depreciation and utilities, professional services, amortization of intangibles and bad debt charges. Accounting for Leases The Company has operating leases for certain facilities, equipment, autos and data centers. As an accounting policy for short-term leases, the Company elected to not recognize a right-of-use asset ("ROU asset") and liability if, at the commencement date, the lease (1) has a term of 12 months or less and (2) does not include renewal and purchase options that the Company is reasonably certain to exercise. Monthly payments on short-term leases are recognized on a straight-line basis over the full lease term. Stock-Based Compensation The Company recognizes stock-based compensation expense related to the estimated fair value of restricted stock awards on a straight-line basis, net of estimated forfeitures, over the requisite service period of the awards, which is generally the vesting term of three tock-based compensation related to performance share grants are measured based on grant date fair value and expensed on a graded basis over the service period of the awards, which is generally a performance period of three years. The performance conditions are based on the Company's achievement of revenue growth and return on invested capital over the performance period, and are evaluated for the probability of vesting at the end of each reporting period with changes in expected results cumulatively recognized as an adjustment to expense. The assumptions used to calculate the fair value of restricted stock grants are evaluated and revised, as necessary, to reflect market conditions and the Company’s experience. Income Taxes Income taxes are calculated using an asset and liability approach. The provision for income taxes includes federal, state and foreign taxes currently payable, and deferred taxes due to temporary differences between the financial statement and tax bases of assets and liabilities. In addition, future tax benefits are recognized to the extent that realization of such benefits is more likely than not. This method gives consideration to the future tax consequences of the deferred income tax items and immediately recognizes changes in income tax laws in the year of enactment. Net Income per Share Basic net income per common share is computed based on the weighted average number of common shares outstanding. Potentially dilutive shares are included in the diluted per-share calculations using the treasury stock method for all periods when the effect of their inclusion is dilutive. Accounting Standard Adopted In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update ("ASU") 2023-07 requiring enhanced segment disclosures. ASU 2023-07 requires disclosure of significant segment expenses regularly provided to the chief operating decision maker (“CODM”) included within segment operating profit or loss. Additionally, ASU 2023-07 requires a description of how the CODM utilizes segment operating profit or loss to assess segment performance. The requirements of the ASU are effective for the annual period ending December 31,2024, and requires companies to apply them retrospectively. The Company adopted the ASU using retrospective transition method, and it had no impact on the Company’s consolidated financial statements. Refer to Note 19 Accounting Standards Not Yet Adopted In December 2023, the FASB issued ASU 2023-09 requiring enhanced income tax disclosures. The ASU requires disclosure of specific categories and disaggregation of information in the rate reconciliation table. The ASU also requires disclosure of disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted and the amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is in the process of analyzing the impact of the ASU on its Consolidated Financial Statements. In November 2024, the FASB issued ASU 2024-03 requiring public companies to disclose, in interim and reporting periods, additional information about certain expenses in the financial statements. The ASU is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted and is effective on either a prospective basis or retrospective basis. The Company is currently assessing the potential impacts of adoption on the consolidated financial statements. The Company does not believe other new accounting pronouncements issued by the FASB will have a material impact on its consolidated financial statements.

Acquisitions

Acquisitions	12 Months Ended
	Dec. 31, 2024
Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	Acquisitions On April 1, 2022, the Company completed its acquisition of 100.0% of the outstanding equity interest of FIXCO Invest S.A.S. (together with its subsidiaries, "ETANCO") for total purchase consideration of $805.4 million, net of cash acquired (the "Acquisition"). The Acquisition was completed pursuant to the securities purchase agreement dated January 26, 2022, as amended (the “SPA”), by and among the Company, Fastco Investment, Fastco Financing, LRLUX and certain other security holders. The purchase price for the Acquisition was paid using cash on hand and borrowings in the amount of $250.0 million under the revolving credit facility and $450.0 million under the term loan facility. See Note 14 ETANCO is a manufacturer and distributor of fastener and fixing products headquartered in France and its primary product applications directly align with the addressable markets in which the Company operates. The Acquisition allows the Company to enter into new commercial building markets such as façades, waterproofing, safety and solar, as well as grow its share of direct business sales in Europe. ETANCO’s results of operations were included in the Company's consolidated financial statements from the April 1, 2022 acquisition date, and as such, only includes ETANCO's results of operations for the nine months ending December 31, 2022. ETANCO had net sales of $212.6 million and a net loss of $5.9 million for the nine months ended December 31, 2022, which includes costs related to fair-value adjustments for acquired inventory, amortization of acquired intangible assets, and expenses incurred for integration. Purchase price allocation The Acquisition was accounted for using the acquisition method of accounting in accordance with A SC 805, Business Combinations (“ASC 805”) which requires, among other things, assets acquired and liabilities assumed in a business combination be recorded at fair value as of the acquisition date with limited exceptions. The allocation of the $824.4 million purchase price, including cash, to the estimated fair values of the tangible and intangible assets acquired and liabilities assumed is as follows: (in thousands) Amount Cash and cash equivalents $ 19,010 Trade accounts receivable, net 63,607 Inventory 107,185 Other current assets 4,491 Property and equipment, net 89,695 Operating lease right-of-use assets 5,361 Goodwill 365,591 Intangible assets, net 357,327 Other noncurrent assets 2,881 Total assets 1,015,148 Trade accounts payable 46,457 Accrued liabilities and other current liabilities 22,079 Operating lease liabilities 5,176 Deferred income tax and other long-term liabilities 117,031 Total purchase price $ 824,405 Trade accounts receivable, net The gross amount of trade receivables acquired was approximately $67.4 million, of which $66.0 million was collected, in excess of the original collectible estimate of $63.6 million. Inventory Acquired inventory primarily consists of raw materials and finished goods consisting of building and construction materials products. The Company adjusted acquired finished goods higher by $13.6 million to estimated fair value based on expected selling prices less a reasonable amount for selling efforts. The fair value adjustment was fully recognized as a component of cost of sales over the inventory’s estimated turnover period during the nine months ended December 31, 2022. There were no such adjustments during the twelve months ended December 31, 2024 and 2023. Property and equipment, net Acquired property and equipment includes land of $16.1 million, buildings and site improvements of $32.5 million, and machinery, equipment, and software of $41.1 million. The estimated fair value of property and equipment was determined primarily using market and/or cost approach methodologies. The acquired fair value for buildings and site improvements will depreciate on a straight-line basis over the estimated useful lives of the assets for a period of up to sixteen years, and machinery, equipment and software will depreciate on an accelerated basis over an estimated useful life of three Goodwill The excess of purchase price over the net assets acquired is recognized as goodwill and relates to the value that is expected from the acquired assembled workforce as well as the increased scale and synergies resulting from the integration of both businesses. The goodwill recognized from the Acquisition is not deductible for local income tax purposes. Goodwill was allocated to components within ETANCO. Intangible assets, net The estimated fair value of intangible assets acquired was determined primarily using income approach methodologies. The values allocated to intangible assets and the useful lives are as follows: (in thousands except useful life) Weighted-average useful life (in years) Amount Customer relationships 15 $ 248,398 Trade names Indefinite 93,811 Developed technology 10 11,256 Patents 8 3,862 $ 357,327 The acquired definite-lived intangible assets will be amortized on a straight-line basis over estimated useful lives, which approximates the pattern in which these assets are utilized. Deferred taxes As a result of the increase in fair value of inventory, property and equipment, and intangible assets, deferred tax liabilities of $105.9 million were recognized, primarily due to intangible assets. Acquisition and integration related costs During the year ended December 31, 2022, the Company incurred acquisition and integration related expenses of $17.3 million. These costs were included in the Company's income from operations. Unaudited pro forma results The following unaudited pro forma combined financial information presents estimated results as if the Company acquired ETANCO on January 1, 2021. The unaudited pro forma financial information as presented below is for informational purposes only and does not purport to actually represent what the Company’s combined results of operations would have been had the Acquisition occurred on January 1, 2021, or what those results will be for any future periods. The following unaudited pro forma consolidated financial information has been prepared using the acquisition method of accounting in accordance with U.S. GAAP: Years Ended December 31, (in thousands) 2022 2021 Net sales $ 2,195,271 $ 1,884,654 Net income $ 363,527 $ 261,389 Pro forma earnings per common share: Basic $ 8.47 $ 6.03 Diluted $ 8.44 $ 6.00 Weighted average shares outstanding: Basic 42,925 43,325 Diluted 43,047 43,532 The unaudited pro forma results above includes the following non-recurring charges to net income: 1) Acquisition and integration related costs of $17.3 million which were incurred during the twelve months ended December 31, 2022, were adjusted as if such costs were incurred during the twelve months ended December 31, 2021. 2) The $13.6 million fair value adjustment for inventory recognized during the twelve months ended December 31, 2022, was adjusted as if incurred during the twelve months ended December 31, 2021. 3) Net income for ETANCO includes adjustments of $0.4 million and $3.2 million to conform ETANCO’s historical financial results prepared under French GAAP to U.S. GAAP for the twelve months ended December 31, 2022, and December 31, 2021, respectively. The U.S. GAAP adjustments are primarily related to share-based payments expense on awards that were settled prior to the Acquisition, and costs incurred and capitalized by ETANCO on its historical acquisitions. During the year ended December 31, 2024, the Company also completed three other acquisitions that were not material to the Company's consolidated financial statements, individually and in aggregate. Accordingly, pro-forma historical results of operations related to these business acquisitions during the year ended December 31, 2024 have not been presented, but summarized below. On June 1, 2024, the Company completed the acquisition of all of the operating assets and assumed liabilities of Calculated Structured Designs, Inc. ("CSD"), a software development company providing solutions for the engineered wood, engineering, design and building industries in North America, Australia and the UK. On August 1, 2024, the Company completed the acquisition of all of the operating assets and assumed liabilities of Monet DeSauw Inc. and certain properties of Callaway Properties, LLC (together with its subsidiaries, “Monet”) for a total purchase consideration of approximately $48.7 million net of cash received and liabilities assumed. Monet specializes in the production of large-scale saws and material handling equipment for the truss industry in the United States. On September 1, 2024, the Company completed the acquisition of all of the operating assets and assumed liabilities of QuickFrames USA, LLC (QuickFrames), a manufacturer of pre-engineered structural support systems for commercial construction with sales in North America. The following table summarizes the Company's preliminary purchase price allocations of assets acquired and liabilities assumed as of the acquisition dates for the twelve months ended December 31, 2024, including the related estimated useful lives, where applicable: Amounts (in thousands) Estimated Useful Life (in years) Net working capital $ 3,165 Land 310 Machinery and Equipment 396 1 - 5 Building Improvements 500 28 Intangible assets 8 Tradename and other (definite) 1,088 10 Tradename (indefinite) 11,900 Customer relationships 10,761 7 Developed technology 13,008 5 - 10 Patent 15,800 10 Goodwill 32,821 Liabilities assumed (10,482) Total net assets acquired and liabilities assumed $ 79,267 The valuations of assets acquired and liabilities assumed for CSD and QuickFrames have not yet been finalized as of December 31, 2024, and finalization of these valuations during the measurement period could result in a change in the amounts recorded. The completion of the valuations for CSD and QuickFrames will occur no later than one year from the acquisition dates as required by U.S. GAAP. The amount of goodwill generated from these acquisitions is deductible for tax purposes.

Revenue from Contracts with Cus

Revenue from Contracts with Customers	12 Months Ended
	Dec. 31, 2024
Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customer	Revenue from Contracts with Customers Disaggregated revenue The Company disaggregates net sales into the following major product groups as described in its segment information included in these financial statements under Note 1 9 Wood Construction Products Revenue . Wood construction products represented approximately 85.1%, 85.4%, and 87.0% of total net sales in the years ended December 31, 2024, 2023, and 2022 respectively. Concrete Construction Products Revenue. Concrete construction products represented approximately 14.8%, 14.5%, and 13.0% of total net sales in the years ended December 31, 2024, 2023 and 2022, respectively. Customer acceptance criteria. Generally, there are no customer acceptance criteria included in the Company’s standard sales agreement with customers. When an arrangement with the customer does not meet the criteria to be accounted for as a revenue contract under the standard, the Company recognizes revenue in the amount of nonrefundable consideration received when the Company has transferred control of the goods or services and has stopped transferring (and has no obligation to transfer) additional goods or services. The Company offers certain customers discounts for paying invoices ahead of the due date, which are generally 30 to 60 days after the issue date. Other revenue . Service sales, representing after-market repair and maintenance, engineering activities and software license sales and services were less than 0.5% of net sales for 2024, 2023 and 2022 and recognized as the services are completed or by transferring control over a product to a customer at a point in time. Services may be sold separately or in bundled packages. The typical contract length for services is generally less than one year. For bundled packages, the Company accounts for individual services separately when they are distinct within the context of the contract. A distinct service is separately identifiable from other items in the bundled package if a customer can benefit from it on its own or with other resources that are readily available to the customer. The consideration (including any discounts) is allocated between separate services in a bundle based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the services. Reconciliation of contract balances Contract assets are the right to receive consideration in exchange for goods or services that the Company has transferred to a customer when that right is conditional on something other than the passage of time. Contract liabilities are recorded for any services billed to customers and not yet recognizable if the contract period has commenced or for the amount collected from customers in advance of the contract period commencing. As of December 31, 2024 and 2023, the Company had no material contract assets from contracts with customers . Other accounting considerations Volume discounts. Volume discounts are accounted for as variable consideration because the transaction price is uncertain until the customer completes or fails to purchase the specified volume of purchases (consideration is contingent on a future outcome - occurrence or nonoccurrence). In addition, the Company applies the volume rebate or discount retrospectively, because the final price of each product or services sold depends on the customer's total purchases subject to the rebate program. Estimated rebates are deducted from revenues based on the gross transaction price and historical experience with the customer. Rights of return and other allowances. Rights of return create variability in the transaction price. The Company accounts for returned product during the return period as a refund to customer and not a performance obligation. The estimated allowance for returns is based on historical percentage of returns and allowance from prior periods and the customer's historical purchasing pattern. This estimate is deducted from revenues based on the gross transaction price. Principal versus Agent. The Company considered the principal versus agent guidance of the revenue recognition standard and concluded that the Company is the principal in a third-party transaction. The Company manufactures its products and has control over the transfer of its products to Dealer Distributors, Contract Distributors, and end customers. Costs to obtain or fulfill a contract. Costs incurred to obtain a contract are immaterial. Commission cost is not an incremental cost directly related to obtaining a contract. Shipping costs. The Company recognizes shipping and handling activities that occur after the customer has obtained control of goods as a fulfillment cost rather than as an additional promised service. Therefore, the Company recognizes revenue and accrues shipping and handling costs when the control of goods transfers to the customer upon shipment. Advertising costs. Cooperative advertising and partnership discounts are consideration payable to a customer and not payment in exchange for a distinct product or service at fair value. Estimated cooperative advertising and partnership discounts are reductions of the transaction price.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Stock Repurchases On August 16, 2022, the Inflation Reduction Act of 2022 ("IRA") was signed into law. The provisions included a new Corporate Alternative Minimum Tax "CAMT", an excise tax of 1.0% on stock buybacks, and significant tax incentives for energy and climate initiatives, all effective for tax year 2023 and onwards. The Company is not subject to the provisions of CAMT and does not expect the impact of the remaining provisions to be material. For the fiscal year ended December 31, 2024, the Company repurchased approximately 0.6 million shares of the Company’s common stock in the open market at an average price of $178.83 per share, for a total of $100.0 million under the previously announced $100.0 million share repurchase authorization (which expired at the end of 2024). As of December 31, 2024, the Company accr ued approximately $0.8 million for the excise tax, which is included as a cost of treasury stock; however, this is not reflected in the share repurchase amounts above.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company currently maintains the Simpson Manufacturing Co., Inc. Amended and Restated 2011 Incentive Plan (the “2011 Plan”) as its only equity incentive plan. Under the 2011 Plan, no more than 16.3 million shares of the Company’s common stock in aggregate may be issued, including shares already issued pursuant to prior awards granted under the 2011 Plan. Shares of common stock underlying awards to be issued pursuant to the 2011 Plan are registered under the Securities Act. Under the 2011 Plan, the Company may grant restricted stock and restricted stock units. The Company currently intends to award only performance-based stock units ("PSUs") and/or time-based restricted stock units ("RSUs"). The following table shows the Company’s stock-based compensation activity: Fiscal Years Ended December 31, (in thousands) 2024 2023 2022 Stock-based compensation expense recognized $ 13,112 $ 19,726 $ 12,503 Tax benefit of stock-based compensation expense in provision for income taxes 3,204 4,808 3,133 Stock-based compensation expense, net of tax $ 9,908 $ 14,918 $ 9,370 The Company allocates stock-based compensation expense amongst cost of sales, research and development and other engineering expense, selling expense, or general and administrative expense based on the job functions performed by the employees to whom the stock-based compensation is awarded. Stock-based compensation capitalized in inventory was immaterial for all periods presented. The following table summarizes the Company’s unvested restricted stock unit activity for the year ended December 31, 2024 : Shares (in thousands) Weighted- Aggregate Intrinsic Value * ( in thousands) Unvested Restricted Stock Units (RSUs) Outstanding as of January 1, 2024 378 $ 102.87 $ 74,850 Awarded 161 177.60 Vested (167) 103.64 Forfeited (36) 116.62 Outstanding as of December 31, 2024 336 130.42 55,333 Outstanding and expected to vest at December 31, 2024 327 54,249 * The intrinsic value for outstanding and expected to vest is calculated using the closing price per share of $165.83, as reported by the New York Stock Exchange on December 31, 2024. During the year ended December 31, 2024, the Company granted 156 thousand RSUs and PSUs to the Company’s employees, including officers at an estimated weighted average fair value of $177.73 per share, based on the closing price (adjusted for certain market factors primarily the present value of dividends) of the Company’s common stock on the grant date. The RSUs and PSUs granted to the Company’s employees may be time-based, performance-based or time- and performance-based. Certain of the PSUs are granted to officers and key employees, where the number of performance-based awards to be issued is based on the achievement of certain Company performance criteria established in the award agreement over a cumulative three years period. These awards cliff vest after three years. In addition, these same officers and key employees also receive time-based RSUs, which vest pursuant to a three-year graded vesting schedule. Time and performance-based RSUs granted to the Company’s employees excluding officers and certain key employees, vest ratably over the four-year life of the award and through 2020, required the underlying shares of the Company's common stock to be subject to a performance-based adjustment during the first year and starting in 2021, were time-based awards which vest ratable over the four-year life of the award. The Company’s seven non-employee directors serving during 2024 are entitled to receive approximately $0.9 million in equity compensation annually. The number of shares granted is based on the average closing share price for the Company over the 60 days period prior to approval of the award in the second quarter of each year . In May 2024, the Company granted 4,692 shares of the Company's common stock to the non-employee directors, based on the average closing price of $173.89 per share and recognized total expense of $0.8 million. The total intrinsic value of RSUs and PSUs vested during the years ended December 31, 2024, 2023 and 2022 was $31.8 million, $20.3 million and $25.6 million, respectively, based on the market value on the vest date. As of December 31, 2024, the Company’s aggregate unamortized stock compensation expense was approximately $24.2 million, which is expected to be recognized over a weighted-average period of approximately 2.2 years. Stock Bonus Plan The Company also maintains the Simpson Manufacturing Co., Inc. 1994 Employee Stock Bonus Plan (the “Stock Bonus Plan”), whereby it awards shares of the Company’s common stock to employees, who do not otherwise participate in any of the Company’s equity-based incentive plans and meet minimum service requirements. Shares have generally been awarded under the Stock Bonus Plan following the year in which the respective employee reached his or her tenth, twentieth, thirtieth, fortieth or fiftieth anniversary of employment with the Company or any direct or indirect subsidiary thereof. The Company awarded shares for service through 2024, 2023, and 2022 as shown below: December 31, 2024 2023 2022 Shares to be issued 21,266 9,800 9,300 Shares settled with cash (foreign employees) 763 4,900 7,400 Total awards 22,029 14,700 16,700 As a result, we recorded pre-tax compensation charges of $3.7 million, $1.9 million, and $1.5 million for years ended December 31, 2024, 2023, and 2022, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company enters into derivative instrument agreements, including forward foreign currency exchange contracts, interest rate swaps, and cross currency swaps to manage risk in connection with changes in foreign currency and interest rates. The Company hedges committed exposures and does not engage in speculative transactions. The Company only enters into derivative instrument agreements with counterparties who have highly rated credit. The Company produces certain of its concrete products from a wholly owned subsidiary in China, and as a result is exposed to variability in cash outflows associated with changes in the foreign exchange rate between the U.S. Dollar and the Chinese Yuan (CNY). In November 2022, the Company entered into a series of foreign currency derivative contracts that matured monthly between January 2023 and December 2023. These forward contracts are accounted for as cash flow hedges under the accounting standards, and fair value is included in other current assets or other current liabilities, as applicable, in the consolidated balance sheet. Net deferred gains and losses on these contracts relating to changes in fair value are included in accumulated other OCI and are reclassified into cost of sales in the consolidated statements of operations in the which the hedged items are recorded in the same period the hedged item affects earnings. There were $0.2 million in losses recorded on these contracts during the year ended December 31, 2023 and $0.2 million in losses recorded on these contracts during the year ending December 31, 2024. Beginning in March 2022, the Company entered into a forward foreign currency contract expiring in March 2029 to hedge its exposure to adverse foreign currency exchange rate movements for its operations in Europe and elected the spot method for designating this contract as a net investment hedge with the net interest income from forward points excluded and amortized to interest expense. During May 2022, the Company settled the March 2022 forward foreign currency contract for $3.9 million in cash, which included $0.4 million in recognized forward points, terminated the hedge accounting treatment and simultaneously entered into a new forward foreign currency contract expiring in March 2029 with the same notional amount at a new forward rate. The Company also elected the spot method for designating the May 2022 contract as a net investment hedge. The $3.5 million gain recognized on the March 2022 contract from recognized forward points is deferred in OCI and will remain in OCI until either the sale or substantially complete liquidation of the hedged subsidiaries. Beginning in March 2022, the Company also converted a Euro-denominated ("EUR"), fixed rate obligation into a U.S. Dollar fixed rate obligation using a receive fixed, pay fixed cross currency swap, which was designated as a cash flow hedge. During May 2022, the Company settled the March 2022 cross currency swap for $22.4 million in cash, which was comprised of $21.3 million gain on the swap excluding accrued interest and $1.1 million of net interest income accrued according to the terms of the swap. The Company terminated the hedge accounting treatment and simultaneously entered into a new cross currency swap expiring in March 2029 with a lower notional amount for the US dollar denominated leg at a new US dollar interest rate. An amount of $28.3 million was reclassified out of OCI into earnings to offset the currency loss on the underlying security being hedged resulting in a net $7.0 million hedge accounting balance reserved within OCI, which is being amortized to interest expense in the consolidated statements of operations through the termination of the underlying hedged intercompany debt in March 2029. In addition, the Company converted its domestic U.S. variable rate debt to fixed rate debt using a receive variable, pay fixed interest rate swap expiring March 2027. The interest rate swap contract is also designated as a cash flow hedge. As of December 31, 2024, the aggregate notional amount of the Company's outstanding interest rate contracts, cross currency swap contracts and EUR forward contracts were $388.1 million, $406.9 million, and $321.7 million, respectively. As of December 31, 2023, there were no outstanding forward contracts on its Chinese Yuan denominated purchases. Changes in fair value of any forward contracts that are determined to be ineffective are immediately reclassified from OCI into earnings. There were no amounts recognized due to ineffectiveness during the twelve months ended December 31, 2024. The effects of fair value and cash flow hedge accounting on the consolidated statements of operations for the periods ended December 31, were as follows: 2024 2023 (in thousands) Cost of sales Interest expense, net Other & foreign exchange loss, net Cost of sales Interest expense, net Other & foreign exchange loss, net Total amounts of income and expense line items presented in the Consolidated Statements of Operations in which the effects of fair value or cash flow hedges are recorded $ 1,206,288 $ 5,277 $ (1,209) $ 1,170,048 $ 3,391 $ (1,993) The effects of fair value and cash flow hedging Gain or (loss) on cash flow hedging relationships Interest contracts: Amount of gain or (loss) reclassified from OCI to earnings — 11,712 — — 15,722 — Cross currency swap contract Amount of gain or (loss) reclassified from OCI to earnings — 4,939 26,577 — 5,170 (12,704) Forward contract Amount of gain or (loss) reclassified from OCI to earnings (188) — — (155) — — The effects of derivative instruments on the consolidated statements of operations for the twelve months ended December 31, 2024 and December 31, 2023 were as follows: Cash Flow Hedging Relationships Gain (Loss) Recognized in OCI Location of Gain (Loss) Reclassified from OCI into Earnings Gain (Loss) Reclassified from OCI into Earnings (in thousands) 2024 2023 2024 2023 Interest rate contracts $ 8,589 $ 4,668 Interest expense $ 11,712 $ 15,722 Cross currency contracts 28,974 (14,737) Interest expense 4,939 5,170 Forward contracts (124) FX gain (loss) 26,577 (12,704) Cost of goods sold (188) (155) Total $ 37,563 $ (10,193) $ 43,040 $ 8,033 For the twelve months ended December 31, 2024 and 2023, a gain of $13.9 million and a loss of $11.4 million, respectively, on the net investment hedge were included in OCI. For the twelve months ended December 31, 2024 and 2023, deferred gains from the forward points of $5.1 million for both years were reclassified from OCI to interest expense. As of December 31, 2024, the aggregate fair values of the Company’s derivative instruments on the Consolidated Balance Sheet were comprised of an asset of $32.4 million, of which $13.6 million is included in other current assets other non-current assets deferred income tax and other long-term liabilities As of December 31, 2023, the aggregate fair values of the Company’s derivative instruments on the Consolidated Balance Sheet were comprised of an asset of $21.9 million, of which $14.5 million is included in other current assets other non-current assets deferred income tax and other long-term liabilities As of December 31, 2024, the Company expects it will reclassify net gains of approxi mately $15.0 million, cu rrently recorded in Accumulated Other Comprehensive Income (AOCI), into interest expense in earnings within the next twelve months. However, the actual amount reclassified could vary due to future changes in the fair value of these derivatives.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill The annual changes in the carrying amount of goodwill, by segment, as of December 31, 2024 and 2023, were as follows, respectively: (in thousands) North Europe Asia Total Balance as of January 1, 2023 $ 103,572 $ 390,799 $ 1,301 $ 495,672 Goodwill acquired (2,077) 1 1,497 — (580) Goodwill disposed — (5,678) 2 — (5,678) Foreign exchange 63 13,075 (2) 13,136 Balance as of December 31, 2023 101,558 399,693 1,299 502,550 Goodwill acquired 32,820 — — 32,820 Foreign exchange (230) (22,644) (113) (22,987) Balance as of December 31, 2024 $ 134,148 $ 377,049 $ 1,186 $ 512,383 Goodwill Impairment Testing The Company tests goodwill for impairment at the reporting unit level on an annual basis (in the fourth quarter). The goodwill balance is not amortized to expense, and the Company may assess qualitative or quantitative factors to determine whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount as a basis for determining whether it is necessary to complete quantitative impairment assessments. During fiscal year 2023, we re-evaluated our European reporting units after a full year of operations from our acquisition of ETANCO as it has become further integrated into our other European operations resulting in changes to the management, product distribution, and operations structure of our European operations. As a result of this re-evaluation, all European reporting units were consolidated for reporting purposes into one overall Europe reporting unit. A qualitative assessment was performed immediately preceding the reporting unit change and determined that it was not more likely than not that any impairment existed prior to the reporting unit change. For the Company’s remaining reporting units, the reporting unit level is generally one level below the operating segment, which is at the country level, except for the United States and Australia. The Company determined that the U.S. reporting unit includes four components: Northwest United States, Southwest United States, Northeast United States and Southeast United States. The Australia reporting unit includes two components: Australia and New Zealand. For each of these reporting units, the Company aggregated the components because management concluded that they are economically similar, and that the goodwill is recoverable from these components working in concert. In 2024, the Company applied the ("Step 0") approach to assess qualitative factors related to the goodwill of the reporting units to determine whether it is necessary to perform an impairment test. For this qualitative assessment, the Company assessed various assumptions, events and circumstances that would have affected the estimated fair value of the reporting units. Based on the qualitative assessment performed, the Company concluded that there was no evidence of events or circumstances that would indicate a material change from the Company’s prior year quantitative assessment by reporting unit and therefore, it was more likely than not that the estimated fair value of reporting units exceeded their respective carrying values. In 2023, the Company applied the ("Step 1") approach where the Company compares the fair value of the reporting unit to its carrying value. The fair value calculation uses both the income approach (discounted cash flow method) and the market approach, equally weighted. If the Company determines that the carrying value of the net assets assigned to the reporting unit, including goodwill, exceeds the fair value of the reporting unit, no further action is taken. If the Company determines that the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company will record an impairment charge equal to the difference between the implied fair value of the goodwill and the carrying value. The 2024 and 2023 annual testing of goodwill for impairment did not result in impairment charges. "See Item 7 - Critical Accounting Policies and Estimates - Goodwill and Other Intangible Assets ". Amortizable Intangible Assets Intangible assets from acquired businesses or asset purchases are recognized at their estimated fair values on the date of acquisition and consist of patents, unpatented technology, non-compete agreements, trademarks, customer relationships and other intangible assets. Finite-lived intangibles are amortized to expense over the applicable useful lives, ranging from three based on the nature of the asset and the underlying pattern of economic benefit as reflected by future net cash inflows. The Company performs an impairment test of finite-lived intangibles whenever events or changes in circumstances indicate their carrying value may be impaired. The total gross carrying amount and accumulated amortization of definite-lived intangible assets as of December 31, 2024, was $487.4 million and $112.3 million, respectively. The aggregate amount of amortization expense of intangible assets for the years ended December 31, 2024, 2023 and 2022 was $24.8 million, $23.5 million and $17.4 million, respectively. The weighted-average remaining amortization period for all amortizable intangibles on a combined basis is 9.6 years as of December 31, 2024.

Leases [Abstract]
Leases	Leases The Company has operating leases for certain facilities, equipment and automobiles. The existing operating leases expire at various dates through 2039, some of which include options to extend the leases for up to five years. The Company measured the lease liability at the present value of the lease payments to be made over the lease term. The lease payments are discounted using the Company's incremental borrowing rate.

Debt Disclosure [Abstract]
Debt	Debt On March 30, 2022, the Company entered into the Amended and Restated Credit Facility, which amends and restates the Company's previous Credit Agreement, dated July 27, 2012. The Amended and Restated Credit Facility provides for a 5-year $450.0 million revolving line of credit, which includes a letter of credit-sub-facility up to $50.0 million, and a 5-year term loan facility of $450.0 million. The Company borrowed $450.0 million under the term loan facility to finance a portion of the purchase price for the acquisition of ETANCO. In addition, the Company incurred $6.8 million of debt issuance costs, which are classified in long-term debt on the consolidated balance sheet, that have been deferred and are being amortized over the 5-year terms of the Amended and Restated Credit Facility. During 2024 and 2023, the Company made principal payments of $97.5 million on the Company's outstanding term loan facility. The Company is required to pay an annual revolving credit facility fee of 0.1% to 0.3% per annum on the available commitments under the terms of the Amended and Restated Revolving Credit Facility, regardless of usage, with the applicable fee determined on a quarterly basis based on the Company’s net leverage ratio. The fee is included within Interest expense, net and other in the Company's consolidated statements of operations. Amounts borrowed under the Amended and Restated Credit Facility will bear interest from time to time at either the Base Rate, Spread Adjusted Daily Simple SOFR, Spread Adjusted Term SOFR, Adjusted Eurocurrency Rate or Daily Simple RFR, in each case, as calculated under and as in effect from time to time under the Amended and Restated Credit Facility, plus the Applicable Margin, as defined in the Amended and Restated Credit Facility. The Applicable Margin is determined based on the Company’s net leverage ratio, and ranges (i) from 0.0% to 0.8% per annum for amounts borrowed under the term loan facility that bear interest at Base Rate, (ii) from 0.8% to 1.8% per annum for amounts borrowed under the term loan facility that bear interest at Adjusted Eurocurrency Rate, Spread Adjusted Daily Simple SOFR or Spread Adjusted Term SOFR, (iii) from 0.0% to 0.5% per annum for amounts borrowed under the revolving credit facility that bear interest at Base Rate, (iv) from 0.7% to 1.5% per annum for amounts borrowed under the revolving credit facility that bear interest at Daily Simple RFR (solely to the extent denominated in pound sterling) and (v) from 0.7% to 1.5% per annum for amounts borrowed under the revolving credit facility that bear interest at Daily Simple RFR (other than loans denominated in pound sterling) or Adjusted Eurocurrency Rate. Loans outstanding under the Amended and Restated Credit Facility may be prepaid at any time without penalty except for customary breakage costs and expenses. Based on current principal payment expectations, the annual interest rate on the outstanding debt will be approximately 2.0% over the life of the debt including the effects of the interest rate swap and other derivatives noted above. As of December 31, 2024, in addition to the Amended and Restated Credit Facility, certain of the Company’s domestic subsidiaries are guarantors for a credit agreement between certain of its foreign subsidiaries and institutional lenders. Together, all credit facilities provide the Company with a total of $458.3 million in available revolving credit lines and an irrevocable standby letter of credit in support of various insurance deductibles.

The discretionary amounts for 2024, 2023 and 2022 were equal to 7.0% of qualifying salaries or wages of the covered employees. The Company also has the Simpson Manufacturing Co., Inc. SMW Supplemental 401(k) Plan where it makes periodic contributions to this plan in accordance with the collective bargaining agreement.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Our cybersecurity risk management efforts are an integral part of our overall risk management processes, and we are deeply committed to safeguarding our digital and information technology environment for our employees, customers and vendors. We employ a robust, global and multi-layered security strategy, known as “defense-in-depth,” to assess, identify and manage cybersecurity risks and protect our cyber work environment from potential threats and vulnerabilities. These risks, threats and vulnerabilities include those that could result in significant operational disruption to the Company, such as production disruption, business downtime or loss of containment, as well as risks that could have significant reputational or compliance/regulatory impact. The Company's Information Security team monitors information security risks that target both technology and manufacturing environments and identifies potential risks to Simpson’s information security posture. Any identified risks are prioritized in terms of impact to Simpson’s information security posture and, if critical, addressed immediately or added to Simpson’s information security roadmap. To supplement our internal cybersecurity resources, we also engage external third parties to perform information security assessments, penetration tests and related services to enhance our information security program. Risks Associated with Third-Party Service Providers In addition, we implement robust processes to oversee and manage risks associated with our business arrangements with third-party service providers. All new Simpson third-party business agreements are reviewed and assessed by our Information Security team. We also perform information security program investigations on the security posture of, and assess any publicly known information security events related to, these third-party service providers. If a third party service provider with a business agreement with Simpson experiences an information security breach or incident, our Information Security Team reviews and assesses such event to understand Simpson’s overall exposure to the security incident. Insurance We maintain cybersecurity insurance coverage at industry standard levels as a part of our comprehensive insurance portfolio to help mitigate risk in the event an information security event occurs. Risks from Cybersecurity Threats Despite our security measures, our information technology and infrastructure may remain vulnerable to disruptions, including as a result of attacks by increasingly sophisticated intruders or others who attempt to cause harm to, or otherwise interfere with the normal use of our systems. We have experienced targeted and non-targeted cybersecurity attacks and incidents in the past that have resulted in unauthorized persons gaining access to our information systems and computer networks, and we could in the future experience similar attacks. When we do experience cybersecurity incidents like these and the one we disclosed in October 2023, we aim to utilize that experience to inform and strengthen our cybersecurity management efforts. In response to the October 2023 incident, we increased our phishing awareness training and testing, deployed a cybersecurity tool that continuously monitors and verifies the security posture of individual devices within our network, and deployed technology that provides visibility into our sensitive data across different cloud environments, allowing the identification of potential vulnerabilities and take proactive measures to protect data from unauthorized access, misuse, or theft. We do not believe any risks from cybersecurity threats, including as a result of any previous cybersecurity incident, have materially affected or are reasonably likely to materially affect the Company or our business strategy, results of operations, or financial condition. For additional information regarding the risks from cybersecurity threats we face, see the section captioned “ Risks Relating to Our Intellectual Property and Information Technology ” under Part I, Item 1A “Risk Factors” above.

Operations and Summary of Sig_2

Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of Simpson Manufacturing Co., Inc. and its subsidiaries. Investments in 50.0% or less owned entities are accounted for using either cost or equity method. All significant intercompany transactions have been eliminated. Certain prior years' amounts have been reclassified to conform to the fiscal 2024 presentation. These reclassifications had no impact on the Company's Consolidated Balance Sheets, Consolidated Statements of Operations, Consolidated Statements of Stockholders’ Equity or Consolidated Statements of Cash Flow.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that these consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation under GAAP.
Cash Equivalents	Cash Equivalents The Company classifies investments that are highly liquid and have maturities of three months or less at the date of purchase as cash equivalents. As of December 31, 2024, and 2023, the value of these investments was $49.3 million and $163.6 million, respectively, consisting of money market funds. The value of the investments is based on cost, which approximates fair value based on Level 1 inputs.
Allowance For Doubtful Accounts	Current Estimated Credit Loss - Allowance for doubtful accounts The Company maintains an allowance for doubtful accounts receivable for estimated future expected credit losses resulting from customers' failure to make payments on its accounts receivable. The Company determines the estimate of the allowance for doubtful accounts receivable by considering several factors, including (1) specific information on the financial condition and the current creditworthiness of customers, (2) credit rating, (3) payment history and historical experience, (4) aging of the accounts receivable, and (5) reasonable and supportable forecasts about collectability . The Company also reserves 100.0% of the amounts deemed uncollectible due to a customer's deteriorating financial condition or bankruptcy. Every quarter, the Company evaluates the customer group using the accounts receivable aging report and its best judgment when considering changes in customers' credit ratings, level of delinquency, customers' historical payments and loss experience, current market and economic conditions, and expectations of future market and economic conditions. The changes in the allowance for credit losses for the year ended December 31, 2024 are outlined in the table below: Balance Balance (in thousands) December 31, 2023 Expense (Deductions), net Write-Offs 1 December 31, 2024 Allowance for credit losses $ 3,881 $ 115 $ 998 $ 2,998 1 Amount is net of recoveries and the effect of foreign currency fluctuations for the year ended December 31, 2024
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash in banks, short-term investments in money market funds and trade accounts receivable. The Company maintains its cash on demand deposit and in money market accounts held in 35 banks, and at times these cash and investments may be in excess of amounts insured by the Federal Deposit Insurance Corporation (FDIC). However, we have not experienced any losses on these accounts.
Inventory Valuation	Inventory Valuation Inventories are stated at the lower of cost or net realizable value. Cost includes all costs incurred in bringing each product to its present location and condition, as follows: • Raw materials and purchased finished goods for resale — principally valued at a cost determined on a weighted average basis; and • In-process products and finished goods — the cost of direct materials and labor plus attributable overhead based on a normal level of activity. The Company applies net realizable value when making estimates for obsolescence to the gross value of inventory. Estimated net realizable value is based on estimated selling price less further costs expected to be incurred through completion and disposal. The Company impairs slow-moving products by comparing inventories on hand to projected demand. If on-hand supply of a product exceeds projected demand or if the Company believes the product is no longer marketable, the product is considered obsolete inventory. The Company revalues obsolete inventory to its net realizable value and has consistently applied this methodology. When impairments are established, a new cost basis of the inventory is created . An unexpected change in market demand, building codes or buyer preferences could reduce the rate of inventory turnover and require the recognition of more obsolete inventory.
Warranties and Recalls	Warranties and Recalls
Equity Investments	Equity Investments The Company accounts for investments and ownership interests under either cost or the equity method accounting when it has the ability to exercise significant influence but does not have a controlling financial interest. The Company records its interest in the net earnings of its equity method investees, along with adjustments for unrealized profits or losses within earnings or loss from equity interests in the consolidated statement of operations. The investment is reviewed for impairment whenever factors indicate the carrying amount might not be recoverable and the decrease in value, if any, is recognized in the period the impairment occurs in the consolidated statement of operations.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between unrelated market participants. As such, fair value is a market-based measurement that is determined based on assumptions that unrelated market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified under a three-tier fair valuation hierarchy based on the observability of the inputs available in the market: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying amounts of trade accounts receivable, accounts payable, accrued liabilities and other current liabilities approximate fair value due to the short-term nature of these instruments. The fair values of the Company's investments and liabilities in the deferred compensation plan are classified as Level 1 within the fair value hierarchy, and are subject to investment risks. The fair values of interest rate and foreign currency contracts are classified as Level 2 within the fair value hierarchy. The fair values of the Company’s contingent consideration related to acquisitions is classified as Level 3 within the fair value hierarchy, as these amounts are based on unobservable inputs such as management estimates and entity-specific assumptions and are evaluated on an ongoing basis. The following tables summarize the financial assets and financial liabilities measured at fair value for the Company as of December 31, 2024 and 2023: 2024 2023 (in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Cash equivalents (1) $ 49,273 $ — $ — $ 163,558 $ — $ — Term loan due 2027 (2) — 388,125 — — 410,625 — Revolver due 2027 (2) — — — — 75,038 — Derivative instruments - assets (3) — 32,355 — — 21,835 — Derivative instruments - liabilities (3) — 7,198 — — 30,111 — Investment in deferred compensation plan (4) 944 — — — — — Deferred compensation plan liabilities (4) 1,974 — — — — — Contingent considerations — — 5,400 — — 6,600 (1) The carrying amounts of cash equivalents, representing money market funds traded in an active market with relatively short maturities, are reported on the consolidated balance sheet as of December 31, 2024 and 2023 as a component of "Cash and cash equivalents". (2) The carrying amounts of our term loan and revolver approximate fair value as of December 31, 2024 and 2023 based upon their terms and conditions as disclosed in Note 14 (3) Derivatives for interest rate, foreign exchange, and forward swap contracts are discussed in Note 9 (4) Non-qualified deferred compensation plan. Derivative Instruments The Company uses derivative instruments as a risk management tool to mitigate the potential impact of certain market risks. Foreign currency and interest rate risk are the primary market risks the Company manages through the use of derivative instruments, which are accounted for as cash flow hedges or net investment hedges under the accounting standards and carried at fair value as other current or noncurrent assets or as other current or other long-term liabilities in the consolidated balance sheets. Assets and liabilities with the legal right of offset are not offset in the consolidated balance sheets. Net deferred gains and losses related to changes in fair value of cash flow hedges are included in accumulated other comprehensive income/loss ("OCI"), a component of stockholders' equity in the consolidated balance sheets; and are reclassified into the line item in the consolidated statement of operations in which the hedged items are recorded in the same period the hedged item affects earnings. The effective portion of gains and losses attributable to net investment hedges is recorded net of tax to OCI to offset the change in the carrying value of the net investment being hedged. Recognition in earnings of amounts previously recorded to OCI are limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. Changes in fair value of any derivatives that are determined to be ineffective are immediately reclassified from OCI into earnings. Deferred Compensation Plan The Company established a non-qualified deferred compensation plan ("DCP" or “the Plan”) in April 2023 for eligible employees and members of the Board of Directors. The Plan provides eligible participants the opportunity to defer and invest a specified percentage of their compensation, including the Company stock awards upon vesting. The Plan is a non-qualified plan that is informally funded by assets in a rabbi trust, which restricts the Company's use and access to the assets held but is subject to the claims of the Company's creditors in the event that the Company becomes insolvent. The amount of compensation to be deferred by participants are based on their own elections and are adjusted for any investment changes that the participants direct. This plan does not provide for employer contributions. The Plan permits diversification of vested shares (common stock) into other equity securities subject to a six-month holding period subsequent to vesting. Accounting for deferred common stock will be under either plan C or plan D. Accounting will depend on whether or not the employee has diversified the common stock. Under plan C, diversification is permitted but the employee has not diversified. Under plan D, diversification is permitted and the employee has diversified. For common stock that have not been diversified, the employer stock held in the deferred compensation plan is classified in a manner similar to treasury stock and presented separately on the consolidated balance sheets as the Company's common stock held by the non-qualified deferred compensation plan. Common stock will be recorded at fair value of the stock at the time it vested, subsequent changes in the value of the common stock is not recognized. The deferred compensation obligations are measured independently at fair value of the common stock with a corresponding charge or credit to compensation cost. Fair value is determined as the product of the common stock and the closing price of the stock each reporting period. Under plan D, assets held by the rabbi trust are subject to applicable GAAP. The deferred compensation obligation is measured independently at fair value of the underlying assets. The Company previously presented certain DCP transactions within existing financial statement line items of the consolidated balance sheets and consolidated statement of stockholders’ equity for periods ended December 31, 2023 . For the year ended December 31, 2024, the Company presented t he equity balances related to "Non-qualified deferred compensation plan share awards" as mezzanine equity for $7.8 million and they were combined with stock-based compensation expense in the consolidated statement of stockholders’ equity for the year ended December 31, 2024 . The Company has evaluated the errors both qualitatively and quantitatively and has concluded that they have immaterial impact on the periods presented.
Property, Plant and Equipment including Depreciation and Amortization	Property, Plant and Equipment Property, plant and equipment are carried at cost. Major renewals and betterments are capitalized while maintenance and repairs are expensed as incurred. When assets are sold or retired, their costs and accumulated depreciation are removed from the accounts, and the resulting gains or losses are reflected in the consolidated statements of operations. The ASC 350 Intangibles—Goodwill and Other provides guidance on capitalization of the costs incurred for computer software developed or obtained for internal use. The Company capitalizes qualified external costs and internal costs related to the purchase and implementation of software projects used for business operations and engineering design activities. Capitalized software costs primarily include purchased software, internal costs and external consulting fees. Capitalized software projects are amortized over the estimated useful lives of the software. Depreciation and Amortization Software, including amounts capitalized for internally developed software is amortized on a straight-line basis over an estimated useful life of three three improvements are amortized using the straight-line method over the shorter of the expected life or the remaining term of the lease. Purchased intangible assets with finite useful lives are amortized using the straight-line method over the estimated useful lives of the assets.
Common Stock and Preferred Stock	Preferred Stock The Company’s Board of Directors has the authority to issue authorized and unissued preferred stock in one o r more series with such designations, rights and preferences as may be determined from time to time by the Board of Directors. Accordingly, the Board of Directors is empowered, without stockholder approval, to issue preferred stock with dividend, redemption, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of the Company’s common stock. Common Stock Subject to the rights of holders of any preferred stock that may be issued in the future, holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by the Board of Directors out of legally available funds, and in the event of liquidation, dissolution or winding-up of the Company, to share ratably in all assets available for distribution. The holders of common stock have no preemptive or conversion rights. Subject to the rights of any preferred stock that may be issued in the future, the holders of common stock are entitled to one vote per share on any matter submitted to a vote of the stockholders. A director in an uncontested election is elected if the votes cast “for” such director’s election exceed the votes cast “against” such director’s election, except that, if a stockholder properly nominates a candidate for election to the Board of Directors, the candidates with the highest number of affirmative votes (up to the number of directors to be elected) are elected. There are no redemption or sinking fund provisions applicable to common stock.

Revenue Recognition	Revenue Recognition Generally, the Company's revenue contract with a customer exists when (1) the goods are shipped, services are rendered, and the related invoice is generated, (2) the duration of the contract does not extend beyond the promised goods or services already transferred and (3) the transaction price of each distinct promised product or service specified in the invoice is based on its relative stated standalone selling price. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer at a point in time. Our shipping terms provide the primary indicator of the transfer of control. The Company's general shipping terms are Incoterm C.P.T. (F.O.B. shipping point), where the title, and risk and rewards of ownership transfer at the point when the products are no longer on the Company's premises. Other Incoterms are allowed as exceptions depending on the product or service being sold and the nature of the sale. The Company recognizes revenue based on the consideration specified in the invoice with a customer, excluding any sales incentives, discounts, and amounts collected on behalf of third parties (i.e., governmental tax authorities). Based on historical experience with the customer, the customer's purchasing pattern, and its significant experience selling products, the Company concluded that a significant reversal in the cumulative amount of revenue recognized would not occur when the uncertainty (if any) is resolved (that is, when the total amount of purchases is known). Contract liability is recorded when consideration is received from a customer and the Company has remaining unsatisfied performance obligations. The
Cost of Sales	Cost of Sales Cost of sales includes material, labor, factory and tooling overhead, shipping, and freight costs.

The performance conditions are based on the Company's achievement of revenue growth and return on invested capital over the performance period, and are evaluated for the probability of vesting at the end of each reporting period with changes in expected results cumulatively recognized as an adjustment to expense. The assumptions used to calculate the fair value of restricted stock grants are evaluated and revised, as necessary, to reflect market conditions and the Company’s experience.
Income Taxes	Income Taxes

Leases [Abstract]
Lease, Cost	Leases The Company has operating leases for certain facilities, equipment and automobiles. The existing operating leases expire at various dates through 2039, some of which include options to extend the leases for up to five years. The Company measured the lease liability at the present value of the lease payments to be made over the lease term. The lease payments are discounted using the Company's incremental borrowing rate. The Company measured the right-of-use ("ROU") assets at the amount at which the lease liability is recognized plus initial direct costs incurred or prepayment amounts. The ROU assets are amortized on a straight-line basis over the lease term. The following table provides a summary of operating leases included on the consolidated balance sheets as of December 31, 2024, and 2023, and consolidated statements of operations, and consolidated statements of cash flows for the years ended December 31, 2024 and 2023: Consolidated Balance Sheets Line Item As of December 31, (in thousands) 2024 2023 Assets Operating lease right-of-use assets $ 93,933 $ 68,792 Liabilities Accrued expenses and other current liabilities $ 19,415 $ 14,954 Operating lease liabilities 76,184 55,324 Total operating lease liabilities $ 95,599 $ 70,278 The components of operating lease expense were as follows: Consolidated Statements of Operations Line Item Years Ended (in thousands) 2024 2023 Lease cost General administrative expenses and $ 19,938 $ 16,936 Supplemental cash flow information related to leases is as follows: Years Ended (in thousands) 2024 2023 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 19,243 $ 15,859 Operating right-of-use assets obtained in exchange for new lease liabilities Operating leases $ 46,482 $ 23,074 The following table summarizes the Company’s lease terms and discount rates as of December 31, 2024 : Years Ended 2024 2023 Weighted-average remaining lease terms (in years): Operating leases 6.4 5.5 Weighted-average discount rate: Operating leases 5.3 % 4.9 %
