NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(dollars and shares in thousands, except per share data)

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Organization and Ownership Structure — Atkore Inc. (the “Company”, “Atkore” or “AI”) is a leading manufacturer of Electrical products primarily for the non-residential construction and renovation markets and Safety & Infrastructure solutions for the construction and industrial markets. Atkore was incorporated in the State of Delaware on November 4, 2010 under the name Atkore International Group, Inc. Atkore is the sole stockholder of Atkore International Holdings Inc. (“AIH”), which in turn is the sole stockholder of Atkore International Inc. (“AII”).

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable, and installation accessories. This segment serves contractors, in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security, and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended September 30, 2021, filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 18, 2021, and should be read in conjunction with those consolidated financial statements and the notes thereto. Certain information and disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited condensed consolidated financial statements include the assets and liabilities used in operating the Company’s business. All intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or disposed of are included in the unaudited condensed consolidated financial statements from the effective date of acquisition or up to the date of disposal.

These statements include all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. The results reported in these unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year.

Fiscal Periods — The Company has a fiscal year that ends on September 30. The Company’s fiscal quarters typically end on the last Friday in December, March and June as it follows a 4-5-4 calendar.

Use of Estimates — The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclose contingent assets and liabilities at the date of the condensed consolidated financial statements and report the associated amounts of revenues and expenses. Actual results could differ materially from these estimates.

Recent Accounting Pronouncements

A summary of recently adopted accounting guidance is as follows. Adoption dates are on the first day of the fiscal year indicated below, unless otherwise specified.

ASU	Description of ASU	Impact to Atkore	Adoption Date
2019-12 Simplifying the accounting for income taxes (Topic 740)	The ASU eliminates certain existing exceptions related to the general approach in ASC 740 relating to franchise taxes, reducing complexity in the interim period accounting for year to date loss limitations and changes in tax laws and clarifying the accounting for transactions outside of a business combination that result in a step up in the tax basis of goodwill.	The Company adopted this standard in the first quarter of 2022. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.	2022

2. REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company’s revenue arrangements primarily consist of a single performance obligation to transfer promised goods which is satisfied at a point in time when title, risks and rewards of ownership, and subsequently control have transferred to the customer. This generally occurs when the product is shipped to the customer, with an immaterial amount of transactions in which control transfers upon delivery. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations.

The Company has certain arrangements that require it to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of products to be returned. The Company principally relies on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of sale and to reduce the transaction price. These arrangements include sales discounts and allowances, volume rebates, and returned goods.

The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. The Company also expenses costs incurred to obtain a contract, primarily sales commissions, as all obligations will be settled in less than one year.

The Company typically receives payment 30 to 60 days from the point it has satisfied the related performance obligation. See Note 16, “Segment Information” for revenue disaggregated by geography and product categories.

3. ACQUISITIONS

From time to time, the Company enters into strategic acquisitions in an effort to better service existing customers and to obtain new customers.

Fiscal 2022

On June 22, 2022, Atkore International Inc., a wholly-owned subsidiary of the Company acquired all of the outstanding stock of United Poly Systems, LLC (“United Poly”), for a purchase price of $226,506. United Poly is a manufacturer of high density polyethylene (“HDPE”) pressure pipe and conduit, primarily serving the telecommunications, water infrastructure, renewables and energy markets. The purchase price allocation has not been finalized as the Company is finalizing working capital, inventory, intangible asset, deferred tax asset and liabilities and fixed asset fair values.

9

On May 19, 2022, Allied Tube and Conduit Corporation, wholly-owned subsidiary of the Company acquired the assets of Talon Products, LLC (“Talon”), for a purchase price of $4,193. Talon is a manufacturer of non-metallic, injection molded cable cleats, primarily serving the power distribution markets. The purchase price allocation has not been finalized as the Company is finalizing working capital and intangible asset fair values.

On December 21, 2021, Atkore HDPE, LLC and Allied Tube and Conduit Corporation, wholly-owned subsidiaries of the Company, acquired the assets of Four Star Industries LLC (“Four Star”), for a purchase price of $23,195. Four Star is a manufacturer of high density polyethylene (HDPE) conduit, primarily serving the telecommunications, utility, infrastructure and datacom markets. The Company finalized the purchase price allocation of Four Star in the third quarter of fiscal 2022.

On December 20, 2021, Columbia-MBF Inc., a wholly-owned subsidiary of the Company acquired all of the outstanding stock of Sasco Tubes & Roll Forming Inc. (“Sasco”), for a purchase price of $16,184, of which $13,320 was paid at closing and additional purchase price payable of $2,864 was accrued. Sasco is a Canadian manufacturer of metal framing and related products serving the electrical, mechanical, construction and solar industries. The Company finalized the purchase price allocation of Sasco in the third quarter of fiscal 2022.

The acquisitions in fiscal 2022 were funded using cash-on-hand. The Company incurred approximately $3,274 in acquisition-related expenses for these acquisitions, which were recorded as a component of selling, general and administrative expenses.

The purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values. The following table summarizes the Level 3 fair values assigned to the net assets acquired and liabilities assumed as of the acquisition date for fiscal 2022:

(in thousands)	United Poly		Other		Total
Fair value of consideration transferred:
Cash consideration	$	226,506	$	40,306	$	266,812
Purchase price payable	—		3,266		3,266

Accounts receivable	23,679		5,684		29,363
Inventories	13,266		4,821		18,087
Intangible assets	118,670		19,640		138,310
Fixed assets	14,091		2,784		16,875
Accounts payable	(11,940)		(3,995)		(15,935)
Income taxes	(12,189)		(2,075)		(14,264)
Other	(103)		(129)		(232)
Net assets acquired	156,925		26,730		183,655
Excess purchase price attributed to goodwill acquired	$	69,581	$	16,842	$	86,423

The Company estimates $11.7 million of the goodwill recognized on the United Poly acquisition is deductible for tax purposes. Goodwill recognized from the acquisitions in fiscal 2022 consists largely of the synergies and economies of scale from integrating this company with existing businesses.

Pro forma net income	256,356		175,107		696,012		378,795

The pro forma condensed financial information is presented for illustrative purposes only and does not indicate the actual financial results of the Company if the closing of the acquisitions in the current year had been completed on October 1, 2020, nor is it indicative of the results of operations in future periods. Included in the unaudited pro forma financial information for the three and nine months ended June 24, 2022 and June 25, 2021 were pro forma adjustments to reflect the results of operations of the acquisitions in the current year as though those acquisitions were completed as of the beginning of October 1, 2020, as well as the impact of amortizing certain acquisition accounting adjustments such as amortizable intangible assets. The pro forma financial information neither indicates the impact of possible business model changes nor considers any potential impact of current market conditions, expense efficiencies or other factors.

Net sales and net income of the acquired companies are included in the consolidated statement of operations for the quarter and nine months ended June 24, 2022 for the post-acquisition period.

Fiscal 2021

On February 24, 2021, Atkore Southwest, LLC, a wholly-owned subsidiary of the Company acquired the assets of FRE Composites USA Inc. and separately the Company acquired all of the outstanding stock of FRE Composites Inc., collectively described as FRE Composites Group (“FRE Composites”), for a purchase price of $36,993, net of cash received. FRE Composites is a leading manufacturer of fiberglass conduit for the electrical and industrial market. The purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values.

On October 22, 2020, Atkore Plastics Southeast, LLC, a wholly-owned subsidiary of the Company acquired the assets of Queen City Plastics, Inc. (“Queen City Plastics”), a leading manufacturer of PVC conduit, elbows and fittings for the electrical market. The purchase price was allocated to tangible assets acquired and liabilities assumed based on their fair values. The purchase price of $6,214 was deemed immaterial to the Company.

The purchase price for FRE Composites, which was finalized during the fourth quarter of fiscal 2021, was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values.

11

The acquisitions in fiscal 2021 were funded using cash-on-hand. The Company incurred approximately $646 in acquisition-related expenses for these acquisitions, which were recorded as a component of selling, general and administrative expenses.

The following table summarizes the Level 3 fair values assigned to the net assets acquired and liabilities assumed as of the acquisition date for fiscal 2021:

(in thousands)	FRE Composites
Fair value of consideration transferred:
Cash consideration	$	36,993
Fair value of assets acquired and liabilities assumed:
Cash	437
Accounts receivable	2,163
Inventories	3,355
Intangible assets	18,300
Fixed assets	8,509
Accounts payable	(1,186)
Income taxes	(4,293)
Other	(240)
Net assets acquired	27,045
Excess purchase price attributed to goodwill acquired	$	9,948

The Company estimates $1.6 million of the goodwill recognized on the FRE acquisition is deductible for tax purposes. Goodwill recognized from the acquisitions in fiscal 2021 consists largely of the synergies and economies of scale from integrating this company with existing businesses.

The following table summarizes the fair value of intangible assets as of the acquisition date:

	FRE Composites
(in thousands)	Fair Value		Weighted Average Useful Life (Years)
Customer relationships	$	14,700	12
Other	3,600		6
Total intangible assets	$	18,300

Net sales and net income of both the above acquisitions are included in the condensed consolidated statement of operations for the post-acquisition periods. Due to the immaterial nature of these acquisitions, both individually and in the aggregate, the Company did not include the full year pro forma results of operations for the acquisition year or previous years.

4. POSTRETIREMENT BENEFITS

The Company provides pension benefits through a number of noncontributory and contributory defined benefit retirement plans covering eligible U.S. employees. As of September 30, 2017, all defined pension benefit plans were frozen, whereby participants no longer accrue credited service. The net periodic benefit credit was as follows:

6. INCOME TAXES    

For the three months ended June 24, 2022 and June 25, 2021, the Company’s effective tax rate attributable to income before income taxes was 25.7% and 26.0%, respectively. For the three months ended June 24, 2022 and June 25, 2021, the Company’s income tax expense was $88,041 and $61,654 respectively. The decrease in the current period effective tax rate was primarily driven by the prior year one-time tax expense from the deferred remeasurement of our UK subsidiaries due to the enactment of the Finance Act of 2021 which, among other things, changed the UK corporate tax rate from 19% to 25%.

For the nine months ended June 24, 2022 and June 25, 2021, the Company’s effective tax rate attributable to income before income taxes was 24.4% and 24.8%, respectively. For the nine months ended June 24, 2022 and June 25, 2021, the Company’s income tax expense was $223,630 and $126,922 respectively. The decrease in the current period effective tax rate was driven by an increase in the excess tax benefit associated with stock compensation.

A valuation allowance has been recorded against certain net operating losses in certain foreign jurisdictions. A valuation allowance is recorded when it is determined to be more likely than not that these assets will not be fully realized in the foreseeable future. The realization of deferred tax assets is dependent upon whether the Company can generate future taxable income in the appropriate character and jurisdiction to utilize the assets. The amount of the deferred tax assets considered realizable is subject to adjustment in future periods.

13

The Company recognizes the benefits of uncertain tax positions taken or expected to be taken in tax returns in the provision for income taxes only for those positions that we have determined are more likely than not to be realized upon examination. We record interest and penalties related to unrecognized tax benefits as a component of income tax expense. During the nine months ended June 24, 2022, the balance of unrecognized tax benefits decreased by $1,893 primarily due to the resolution of a state tax matter.

For the nine months ended June 24, 2022, the Company made no additional provision for U.S. or non-U.S. income taxes for unrecognized deferred tax liabilities for temporary differences related to basis differences in investments in subsidiaries, as the investments are essentially permanent in duration.

7. EARNINGS PER SHARE

The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all of the net earnings for the period had been distributed. The Company’s participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders.

Basic earnings per common share excludes dilution and is calculated by dividing the net earnings allocated to common stock by the weighted-average number of common stock outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common stock by the weighted-average number of shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

The following table sets forth the computation of basic and diluted earnings per share:

	Three months ended				Nine months ended
(in thousands, except per share data)	June 24, 2022		June 25, 2021		June 24, 2022		June 25, 2021

Net income available to common shareholders	$	250,430	$	171,908	$	681,629	$	377,813
Denominator:
Basic weighted average common shares outstanding	43,072		46,602		44,553		46,771
Effect of dilutive securities: Non-participating employee stock options (1)	558		684		578		742
Diluted weighted average common shares outstanding	43,630		47,286		45,131		47,513
Basic earnings per share	$	5.81	$	3.69	$	15.30	$	8.08
Diluted earnings per share	$	5.74	$	3.64	$	15.10	$	7.95
(1) Stock options to purchase shares of common stock that would have been anti-dilutive are not included in the calculation. There were no anti-dilutive options outstanding during the three months ended June 24, 2022 and June 25, 2021. Additionally, there were no anti-dilutive options outstanding during the nine months ended June 24, 2022 and June 25, 2021.

9. INVENTORIES, NET

A majority of the Company’s inventories are recorded at the lower of cost (primarily last in, first out, or “LIFO”) or market or net realizable value, as applicable. Approximately 85% and 81% of the Company’s inventories were valued at the lower of LIFO cost or market at June 24, 2022 and September 30, 2021, respectively. Interim LIFO determinations, including those at June 24, 2022, are based on management’s estimates of future inventory levels and costs for the remainder of the current fiscal year.

11. GOODWILL AND INTANGIBLE ASSETS

Changes in the carrying amount of goodwill are as follows:    

(in thousands)	Electrical		Safety & Infrastructure		Total
Balance as of September 30, 2021	$	155,471	$	43,577	$	199,048

Goodwill balances as of September 30, 2021 and June 24, 2022 include $3,924 and $43,000 of accumulated impairment losses within the Electrical and Safety & Infrastructure segments, respectively.

The Company assesses the recoverability of goodwill and indefinite-lived trade names on an annual basis in accordance with ASC 350, “Intangibles - Goodwill and Other.” The measurement date is the first day of the fourth fiscal quarter, or more frequently, if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit or the respective indefinite-lived trade name is less than the carrying value.

17

The following table provides the gross carrying value, accumulated amortization and net carrying value for each major class of intangible asset:

		June 24, 2022						September 30, 2021
(in thousands)	Weighted Average Useful Life (Years)	Gross Carrying Value		Accumulated Amortization		Net Carrying Value		Gross Carrying Value		Accumulated Amortization		Net Carrying Value

Other intangible assets consist of definite-lived trade names, technology, non-compete agreements and backlogs. Amortization expense for the three months ended June 24, 2022 and June 25, 2021 was $8,624 and $8,707, respectively. Amortization expense for the nine months ended June 24, 2022 and June 25, 2021 was $25,554 and $25,063, respectively. Expected amortization expense for intangible assets for the remainder of fiscal 2022 and over the next five years and thereafter is as follows:

(in thousands)
Remaining 2022	$	14,334
2023	46,402

Actual amounts of amortization may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets and other events.

12. DEBT

Debt as of June 24, 2022 and September 30, 2021 was as follows:

(in thousands)	June 24, 2022		September 30, 2021
Senior Secured Term Loan Facility due May 26, 2028	$	371,310	$	371,095
Senior Notes due June 2031	400,000		400,000
Deferred financing costs	(11,311)		(12,709)
Long-term debt	$	759,999	$	758,386

The asset-based credit facility (the “ABL Credit Facility”) has aggregate commitments of $325,000. AII is the borrower under the ABL Credit Facility which is guaranteed by the Company and all other

18

subsidiaries of the Company (other than AII) that are guarantors of the Senior Notes. AII’s availability under the ABL Credit Facility was $312,905 and $315,499 as of June 24, 2022 and September 30, 2021.

13. FAIR VALUE MEASUREMENTS

Certain assets and liabilities are required to be recorded at fair value on a recurring basis.

The Company uses a forward currency contract to hedge the effects of foreign exchange relating to one of the Company’s intercompany balances denominated in a foreign currency. This derivative instrument is not formally designated as a hedge by the Company and the remaining term of the instrument is two months. Short-term forward currency contracts are recorded in either other current assets or other current liabilities and long-term forward currency contracts are recorded in either other long-term assets or other long-term liabilities in the condensed consolidated balance sheet. The fair value gains and losses are included in other income, net within the condensed consolidated statements of operations. See Note 5, “Other Income, net” for further detail.

The total notional amounts of undesignated forward currency contracts were £30.6 million and £37.4 million as of June 24, 2022 and September 30, 2021, respectively. Cash flows associated with derivative financial instruments are recognized in the operating section of the condensed consolidated statements of cash flows. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The following table presents the Company’s assets and liabilities measured at fair value:

	June 24, 2022				September 30, 2021
(in thousands)	Level 1		Level 2		Level 1		Level 2
Assets
Cash equivalents	$	97,476	$	—	$	489,987	$	—
Forward currency contracts	—		3,381		—		127
Liabilities
Forward currency contracts	—		472		—		183

The Company’s remaining financial instruments consist primarily of cash, accounts receivable and accounts payable whose carrying value approximate their fair value due to their short-term nature.

The estimated fair value of financial instruments not carried at fair value in the condensed consolidated balance sheets were as follows:

	June 24, 2022				September 30, 2021
(in thousands)	Carrying Value		Fair Value		Carrying Value		Fair Value
Senior Secured Term Loan Facility due May 26, 2028	$	373,000	$	369,852	$	373,000	$	371,486
Senior Notes due June 2031	400,000		340,000		400,000		415,828
Total Debt	$	773,000	$	709,852	$	773,000	$	787,314

In determining the approximate fair value of its long-term debt, the Company used the trading values among financial institutions, and these values fall within Level 2 of the fair value hierarchy. The carrying value of the ABL Credit Facility approximates fair value due to it being a market-linked variable rate debt.

14. COMMITMENTS AND CONTINGENCIES

The Company has obligations related to commitments to purchase certain goods. As of June 24, 2022, such obligations were $238,059 for the rest of fiscal year 2022 and $12,334 for fiscal year 2023 and beyond. These amounts represent open purchase orders for materials used in production.

Insurable Liabilities — The Company maintains policies with various insurance companies for its workers’ compensation, product, property, general, auto, and executive liability risks. The insurance policies that the Company maintains have various retention levels and excess coverage limits. The establishment and update of liabilities for unpaid claims, including claims incurred but not reported, is based on management's estimate as a result of the assessment by the Company's claim administrator of each claim and an independent actuarial valuation of the nature and severity of total claims. The Company utilizes a third-party claims administrator to pay claims, track and evaluate actual claims experience, and ensure consistency in the data used in the actuarial valuation.

Legal Contingencies — Historically, a number of lawsuits have been filed against the Company and the Company has also received other claim demand letters alleging that the Company's anti-microbial coated steel sprinkler pipe, which the Company has not manufactured or sold for several years, is incompatible with chlorinated polyvinyl chloride and caused stress cracking in such pipe manufactured by third parties when installed together in the same sprinkler system, which the Company refers to collectively as the “Special Products Claims.” Tyco International Ltd. (“Tyco”), now Johnson Controls, Inc. (“JCI”), has a contractual obligation to indemnify the Company in respect of all remaining and future claims of incompatibility between the Company's antimicrobial coated steel sprinkler pipe and CPVC pipe used in the same sprinkler system. When Special Products Claims arise, JCI has defended and indemnified the Company as required.

At this time, the Company does not expect the outcome of the Special Products Claims proceedings, either individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations or cash flows, and the Company believes that its reserves are adequate for all remaining contingencies for Special Products Claims.

In addition to the matters discussed above, from time to time, the Company is subject to a number of disputes, administrative proceedings and other claims arising out of the ordinary conduct of the Company’s business. These matters generally relate to disputes arising out of the use or installation of the Company’s products, product liability litigation, contract disputes, patent infringement accusations, employment matters, personal injury claims and similar matters. On the basis of information currently available to the Company, it does not believe that existing proceedings and claims will have a material adverse effect on its business, financial condition, results of operations or cash flows. However, litigation is unpredictable, and the Company could incur judgments or enter into settlements for current or future claims that could adversely affect its business, financial condition, results of operations or cash flows.

15. GUARANTEES

The Company had outstanding letters of credit totaling $12,095 supporting workers’ compensation and general liability insurance policies as of June 24, 2022. The Company also had surety bonds primarily related to performance guarantees on supply agreements and construction contracts, and payment of duties and taxes totaling $30,039 as of June 24, 2022.

In disposing of assets or businesses, the Company often provides representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal fees related to periods prior to disposition. The Company does not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, the Company has no reason to believe that these uncertainties would have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

20

In the normal course of business, the Company is liable for product performance and contract completion. In the opinion of management, such obligations will not have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

16. SEGMENT INFORMATION

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, restructuring costs and transaction costs.

Intersegment transactions primarily consist of product sales at designated transfer prices on an arm’s-length basis. Gross profit earned and reported within the segment is eliminated in the Company’s consolidated results. Certain manufacturing and distribution expenses are allocated between the segments on a pro rata basis due to the shared nature of activities. Recorded amounts represent a proportional amount of the quantity of product produced for each segment. Certain assets, such as machinery and equipment and facilities, are not allocated to each segment despite serving both segments. These shared assets are reported within the Safety & Infrastructure segment. The Company allocates certain corporate operating expenses that directly benefit our operating segments, such as insurance and information technology, on a basis that reasonably approximates an estimate of the use of these services.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read in conjunction with the unaudited condensed consolidated financial statements and related notes included in this report. The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in these forward- looking statements. Factors that could cause or contribute to these differences include those factors discussed below and included or referenced elsewhere in this report, particularly in the sections entitled “Forward-Looking Statements” and “Risk Factors.”

Incremental Market Uncertainties

The outbreak of the novel coronavirus (“COVID-19”) has continued to spread and is currently classified as a pandemic which is contributing to volatility and uncertainty in markets and the global economy. This heightened volatility and uncertainty makes it difficult for us to predict the extent of COVID-19’s impact on our operations going forward.

Factors that contribute to our ability to adjust to the outbreak include benefiting from mostly localized supply chains and continuing to take actions within our control to minimize the disruptive impacts of the outbreak. However, there can be no assurance that we will not be materially and adversely impacted in the future.

In addition to the uncertainties brought about by COVID-19, recent events, including central bank interest rate increases and the Russia-Ukraine conflict, are creating additional uncertainty in the global economy, generally, and in the markets we operate in. COVID-19, the Russia-Ukraine conflict and other factors have had and will continue to have adverse effects on global supply chains, which may impact some aspects of our business. Furthermore, with the onset of hurricane season, we are mindful of the effects that adverse weather can have on our domestic supply chain.

RESULTS OF OPERATIONS

The consolidated results of operations for the three months ended June 24, 2022 and June 25, 2021 were as follows:

Volume	(5.1)	%
Average selling prices	28.6	%
Foreign exchange	(0.8)	%
Acquisitions	1.6	%
Other	0.1	%
Net sales	24.4	%

Net sales increased by $207.9 million, or 24.4%, to $1,061.6 million for the three months ended June 24, 2022, compared to $853.7 million for the three months ended June 25, 2021. The increase in net sales is primarily attributed to increased average selling prices across the Company’s products of $244.0 million which were mostly driven by the PVC pipe and conduit product category within the Electrical segment and increased net sales of $13.8 million from companies acquired during fiscal 2021 and fiscal 2022. These increases are offset by decreased sales volume of $43.9 million across varying product categories within both the Electrical and the Safety & Infrastructure segments. Pricing for PVC products, as well as other parts of the business, is expected to return to more normal historical levels over time, but that time is uncertain.

Cost of sales

	% Change
Volume	(3.6)	%
Average input costs	19.1	%
Foreign exchange	(2.3)	%
Acquisitions	1.8	%
Other	3.1	%
Cost of sales	18.1	%

Cost of sales increased by $92.9 million, or 18.1%, to $607.3 million for the three months ended June 24, 2022 compared to $514.4 million for the three months ended June 25, 2021. The increase was primarily due to higher input costs of steel, copper and PVC resin of $98.0 million and recent acquisitions during fiscal 2021 and fiscal 2022 of $9.3 million partially offset by lower sales volume of $18.7 million across varying product categories within both the Electrical and the Safety & Infrastructure segments.

Selling, general and administrative

Selling, general and administrative expenses increased by $14.1 million, or 17.3%, to $96.0 million for the three months ended June 24, 2022 compared to $81.8 million for the three months ended June 25, 2021. The increase was primarily due to increased general spending on business improvement initiatives of $8.8 million, higher transaction costs of $1.7 million, higher sales commission expense of $3.6 million, higher variable compensation of $1.3 million and recent acquisitions in fiscal 2021 and 2022 of $1.0 million. These increases were partially offset by decreases of $2.3 million spread across a variety of other spend categories.

Intangible asset amortization

Intangible asset amortization expense remained relatively flat at $8.6 million for the three months ended June 24, 2022 compared to $8.7 million for the three months ended June 25, 2021.

Interest expense, net

Interest expense, net decreased by $0.8 million, or 10.5% to $7.2 million for the three months ended June 24, 2022 compared to $8.1 million for the three months ended June 25, 2021. The decrease is

25

primarily due to interest expense being derived from a lower average principal balance resulting from the Company’s fiscal 2021 debt restructuring transactions.

Other income, net

Other income, net decreased to $0.2 million other expense for the three months ended June 24, 2022 compared to $0.5 million other income for the three months ended June 25, 2021. The decrease was primarily due to foreign currency fluctuations.

Income tax expense

The Company’s income tax rate decreased to 25.7% for the three months ended June 24, 2022 compared to 26.0% for the three months ended June 25, 2021. The decrease in the current period effective tax rate was primarily driven by the prior year one-time tax expense from the deferred remeasurement of our UK subsidiaries due to the enactment of the Finance Act of 2021 which, among other things, changed the UK corporate tax rate from 19% to 25%.

SEGMENT RESULTS

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, restructuring costs and transaction costs. We define segment Adjusted EBITDA margin as segment Adjusted EBITDA as a percentage of segment Net sales.

The increase in net sales is primarily attributed to increased average selling prices of $200.1 million which were mostly driven by the PVC pipe and conduit product category and increased net sales of $6.9 million from companies acquired during fiscal 2021 and fiscal 2022. These increases are offset by decreased sales volume of $41.2 million across varying product categories. Pricing for PVC products, as well as other parts of the business, is expected to return to more normal historical levels over time, but that time is uncertain.

Adjusted EBITDA

Adjusted EBITDA for the three months ended June 24, 2022 increased by $83.6 million, or 31.2%, to $351.5 million from $267.8 million for the three months ended June 25, 2021. Adjusted EBITDA margins increased to 42.8% for the three months ended June 24, 2022 compared to 40.5% for the three months ended June 25, 2021. The increase in Adjusted EBITDA and Adjusted EBITDA margins was largely due to higher average selling prices over input costs.

The increase in cost of sales was primarily due to higher input costs for steel, copper and resin of $414.8 million and recent acquisitions in fiscal 2021 and fiscal 2022 of $25.2 million, partially offset by lower sales volume of $59.6 million across varying product categories within both the Electrical and the Safety & Infrastructure segments.

Selling, general and administrative

Selling, general and administrative expenses increased by $52.8 million, or 25.1% to $263.0 million for the nine months ended June 24, 2022 compared to $210.3 million for the nine months ended June 25, 2021. The increase was primarily due to higher sales commission expense of $19.7 million, increased general spending on business improvement initiatives of $18.2 million, transaction costs of $3.3 million, higher variable compensation of $5.5 million, and recent acquisitions in fiscal 2021 and 2022 of $2.6 million. The remaining increase of $3.5 million is spread across a variety of other spend categories.

Intangible asset amortization

Intangible asset amortization expense increased to $25.6 million for the nine months ended June 24, 2022 compared to $25.1 million for the nine months ended June 25, 2021. The increase in intangible asset amortization was driven by the acquisition of definite-lived intangible assets in fiscal 2022.

Interest expense, net

Interest expense, net, decreased by $3.1 million, or 12.5% to $21.7 million for the nine months ended June 24, 2022 compared to $24.8 million for the nine months ended June 25, 2021. The decrease is primarily due to the Company’s principal prepayments in fiscal 2020 and 2021, resulting in a lower principal balance in fiscal 2021 from which interest expense was derived.

Other income, net

Other income, net decreased to $1.0 million for the nine months ended June 24, 2022 compared to $8.2 million for the nine months ended June 25, 2021. The decrease was primarily due to a $6.0 million business interruption insurance recovery in fiscal 2021 from a flood at one of the Company’s manufacturing facilities.

Income tax expense

The Company’s income tax rate decreased to 24.4% for the nine months ended June 24, 2022 compared to 24.8% for the nine months ended June 25, 2021. The decrease in the six month period effective tax rate was primarily due to an increase in the excess tax benefit associated with stock compensation.

LIQUIDITY AND CAPITAL RESOURCES

We believe we have sufficient liquidity to support our ongoing operations and to invest in future growth and create value for stockholders. Our cash and cash equivalents were $186.7 million as of June 24, 2022, of which $46.8 million was held at non-U.S. subsidiaries. Those cash balances at foreign subsidiaries may be subject to withholding or local country taxes if the Company’s intention to permanently reinvest such income were to change and cash was repatriated to the United States.

In general, we require cash to fund working capital investments, acquisitions, capital expenditures, debt repayment, interest payments, taxes and share repurchases. We have access to the ABL Credit Facility to fund operational needs. As of June 24, 2022, there were no outstanding borrowings under the ABL Credit Facility and $12.1 million of letters of credit issued under the ABL Credit Facility. The borrowing base was estimated to be $325.0 million and approximately $312.9 million was available under the ABL Credit Facility as of June 24, 2022. Outstanding letters of credit count as utilization of the commitments under the ABL Credit Facility and reduce the amount available for borrowings.

The agreements governing the Senior Secured Term Loan Facility and the ABL Credit Facility (collectively, the "Credit Facilities") contain covenants that limit or restrict AII’s ability to incur additional indebtedness, repurchase debt, incur liens, sell assets, make certain payments (including dividends) and enter into transactions with affiliates. AII has been in compliance with the covenants under the agreements for all periods presented.

We may from time to time repurchase our debt or take other steps to reduce our debt. These actions may include open market repurchases, negotiated repurchases or opportunistic refinancing of debt. The amount of debt, if any, that may be repurchased or refinanced will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations.

Our use of cash may fluctuate during the year and from year to year due to differences in demand and changes in economic conditions primarily related to the prices of the commodities we purchase.

Capital expenditures have historically been necessary to expand and update the production capacity and improve the productivity of our manufacturing operations.

31

Our ongoing liquidity needs are expected to be funded by cash on hand, net cash provided by operating activities and, as required, borrowings under the ABL Credit Facility. We expect that cash provided from operations and available capacity under the ABL Credit Facility will provide sufficient funds to operate our business, make expected capital expenditures and meet our liquidity requirements for at least the next twelve months, including payments of interest and principal on our debt.

There have been no material changes in our contractual obligations and commitments since the filing of our Annual Report on Form 10-K.

Limitations on distributions and dividends by subsidiaries

AI, AII, and AIH are each holding companies, and as such have no independent operations or material assets other than ownership of equity interests in their respective subsidiaries. Each company depends on its respective subsidiaries to distribute funds to it so that it may pay obligations and expenses, including satisfying obligations with respect to indebtedness. The ability of our subsidiaries to make distributions and dividends to us depends on their operating results, cash requirements and financial and general business conditions, as well as restrictions under the laws of our subsidiaries' jurisdictions.

The agreements governing the Credit Facilities significantly restrict the ability of our subsidiaries, including AII, to pay dividends, make loans or otherwise transfer assets from AII and, in turn, to us. Further, AII's subsidiaries are permitted under the terms of the Credit Facilities to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to AII and, in turn, to us. The Senior Secured Term Loan Facility requires AII to meet a certain consolidated coverage ratio on an incurrence basis in connection with additional indebtedness. The ABL Credit Facility contains limits on additional indebtedness based on various conditions for incurring the additional debt. AII has been in compliance with the covenants under the agreements for all periods presented.

The table below summarizes cash flow information derived from our statements of cash flows for the periods indicated:

	Nine months ended
(in thousands)	June 24, 2022		June 25, 2021
Cash flows provided by (used in):
Operating activities	$	371,776	$	318,621
Investing activities	(336,693)		(74,303)
Financing activities	(421,241)		(135,412)

Operating activities

During the nine months ended June 24, 2022, the Company was provided $371.8 million by operating activities compared to $318.6 million during the nine months ended June 25, 2021. The $53.2 million increase in cash provided was primarily due to higher cash flows from the increase in operating income of $404.0 million. This increase in operating income was offset primarily by increased income tax impacts of $173.7 million and a $173.0 million increase in cash used in working capital primarily due to higher inventory build during the first two quarters of fiscal 2022,

Investing activities

During the nine months ended June 24, 2022, the Company used $336.7 million in investing activities compared to $74.3 million during the nine months ended June 25, 2021. Cash used in acquisitions increased in fiscal 2022 by $212.2 million primarily as a result of the acquisition of United Poly in the third quarter of fiscal 2022. The remaining increase in cash used in investing activities was driven by $47.7 million of additional capital expenditures.

32

Financing Activities

During the nine months ended June 24, 2022, the Company used $421.2 million in financing activities compared to $135.4 million used during the nine months ended June 25, 2021. The increase in cash used in financing activities is primarily due to $286.9 million more cash used to repurchase common stock during the nine months ended June 24, 2022 compared to the same period in the prior year.

There have been no material changes in our critical accounting policies and estimates since the filing of our Annual Report on Form 10-K.

RECENT ACCOUNTING STANDARDS

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements and cautionary statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are based on management’s beliefs and assumptions and information currently available to management. Some of the forward-looking statements can be identified by the use of forward-looking terms such as “believes,” “expects,” “may,” “will,” “shall,” “should,” “would,” “could,” “seeks,” “aims,” “projects,” “is optimistic,” “intends,” “plans,” “estimates,” “anticipates” or other comparable terms. Forward-looking statements include, without limitation, all matters that are not historical facts. They appear in a number of places throughout this Quarterly Report on Form 10-Q and include, without limitation, statements regarding our intentions, beliefs, assumptions or current expectations concerning, among other things, financial position; results of operations; cash flows; prospects; growth strategies or expectations; customer retention; the outcome (by judgment or settlement) and costs of legal, administrative or regulatory proceedings, investigations or inspections, including, without limitation, collective, representative or class action litigation; and the impact of prevailing economic conditions.

Forward-looking statements are subject to known and unknown risks and uncertainties, many of which may be beyond our control. We caution you that forward-looking statements are not guarantees of future performance or outcomes and that actual performance and outcomes, including, without limitation, our actual results of operations, financial condition and liquidity, and the development of the market in which we operate, may differ materially from those made in or suggested by the forward-looking statements contained in this Quarterly Report. In addition, even if our results of operations, financial condition and cash flows, and the development of the market in which we operate, are consistent with the forward-looking statements contained in this Quarterly Report, those results or developments may not be indicative of results or developments in subsequent periods. A number of important factors, including, without limitation, the risks and uncertainties discussed or referenced under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q, could cause actual results and outcomes to differ materially from those reflected in the forward-looking statements. Additional factors that could cause actual results and outcomes to differ from those reflected in forward-looking statements include, without limitation:

•work stoppage or other interruptions of production at our facilities as a result of disputes under existing collective bargaining agreements with labor unions or in connection with negotiations of new collective bargaining agreements, as a result of supplier financial distress, or for other reasons;

•changes in our financial obligations relating to pension plans that we maintain in the United States;

•reduced production or distribution capacity due to interruptions in the operations of our facilities or those of our key suppliers;

•loss of a substantial number of our third-party agents or distributors or a dramatic deviation from the amount of sales they generate;

•security threats, attacks, or other disruptions to our information systems, or failure to comply with complex network security, data privacy and other legal obligations or the failure to protect sensitive information;

•possible impairment of goodwill or other long-lived assets as a result of future triggering events, such as declines in our cash flow projections or customer demand and changes in our business and valuation assumptions;

•safety and labor risks associated with the manufacture and in the testing of our products;

•product liability, construction defect and warranty claims and litigation relating to our various products, as well as government inquiries and investigations, and consumer, employment, tort and other legal proceedings;

•our ability to protect our intellectual property and other material proprietary rights;

•risks inherent in doing business internationally;

•failure to generate sufficient cash flow from operations or to raise sufficient funds in the capital markets to satisfy existing obligations and support the development of our business; and

•other risks and factors described in this Quarterly Report and from time to time in documents that we file with the SEC.

You should read this Quarterly Report completely and with the understanding that actual future results may be materially different from expectations. All forward-looking statements attributable to us or persons acting on our behalf that are made in this Quarterly Report are qualified in their entirety by

34

these cautionary statements. These forward-looking statements are made only as of the date of this Quarterly Report, and we do not undertake any obligation, other than as may be required by law, to update or revise any forward-looking or cautionary statements to reflect changes in assumptions, the occurrence of events, unanticipated or otherwise, and changes in future operating results over time or otherwise.

Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes to the quantitative and qualitative disclosures about market risks previously disclosed in our Annual Report on Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes to our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

For a discussion of certain litigation involving the Company, see Note 14, “Commitments and Contingencies” to our unaudited condensed consolidated financial statements.

Item 1A. Risk Factors

There have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Issuer Purchases of Equity Securities

On November 16, 2021, the board of directors approved a share repurchase program, under which the Company may repurchase up to $400.0 million of its outstanding common stock. On April 26, 2022, the board of directors approved an amendment to the aforementioned plan, extending it to a total repurchase of the Company’s outstanding common stock of $800.0 million. As of June 24, 2022, there was $403.2 million of purchases remaining under the plan. The share repurchase program will be funded from the Company’s available cash balances. This share repurchase program does not obligate the Company to acquire any particular amount of common stock, and it may be terminated at any time at the Company’s discretion.

The following table shows our purchases of our common stock under this plan during fiscal 2022 (in thousands, except per share data):

Period (4-5-4 calendar)	Total Number Of Shares Purchased	Avg Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Maximum Value of Shares that May Yet Be Purchased Under the Program

Basis of Presentation

Organization and Ownership Structure — Atkore Inc. (the “Company”, “Atkore” or “AI”) is a leading manufacturer of Electrical products primarily for the non-residential construction and renovation markets and Safety & Infrastructure solutions for the construction and industrial markets. Atkore was incorporated in the State of Delaware on November 4, 2010 under the name Atkore International Group, Inc. Atkore is the sole stockholder of Atkore International Holdings Inc. (“AIH”), which in turn is the sole stockholder of Atkore International Inc. (“AII”).

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable, and installation accessories. This segment serves contractors, in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security, and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended September 30, 2021, filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 18, 2021, and should be read in conjunction with those consolidated financial statements and the notes thereto. Certain information and disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited condensed consolidated financial statements include the assets and liabilities used in operating the Company’s business. All intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or disposed of are included in the unaudited condensed consolidated financial statements from the effective date of acquisition or up to the date of disposal.

These statements include all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. The results reported in these unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year.

Fiscal Periods — The Company has a fiscal year that ends on September 30. The Company’s fiscal quarters typically end on the last Friday in December, March and June as it follows a 4-5-4 calendar.

Use of Estimates — The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclose contingent assets and liabilities at the date of the condensed consolidated financial statements and report the associated amounts of revenues and expenses. Actual results could differ materially from these estimates.

Recent Accounting Pronouncements

A summary of recently adopted accounting guidance is as follows. Adoption dates are on the first day of the fiscal year indicated below, unless otherwise specified.

ASU	Description of ASU	Impact to Atkore	Adoption Date
2019-12 Simplifying the accounting for income taxes (Topic 740)	The ASU eliminates certain existing exceptions related to the general approach in ASC 740 relating to franchise taxes, reducing complexity in the interim period accounting for year to date loss limitations and changes in tax laws and clarifying the accounting for transactions outside of a business combination that result in a step up in the tax basis of goodwill.	The Company adopted this standard in the first quarter of 2022. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements.	2022

REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue from Contract with Customer [Abstract]

REVENUE FROM CONTRACTS WITH CUSTOMERS

2. REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company’s revenue arrangements primarily consist of a single performance obligation to transfer promised goods which is satisfied at a point in time when title, risks and rewards of ownership, and subsequently control have transferred to the customer. This generally occurs when the product is shipped to the customer, with an immaterial amount of transactions in which control transfers upon delivery. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations.

The Company has certain arrangements that require it to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of products to be returned. The Company principally relies on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of sale and to reduce the transaction price. These arrangements include sales discounts and allowances, volume rebates, and returned goods.

The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. The Company also expenses costs incurred to obtain a contract, primarily sales commissions, as all obligations will be settled in less than one year.

The Company typically receives payment 30 to 60 days from the point it has satisfied the related performance obligation. See Note 16, “Segment Information” for revenue disaggregated by geography and product categories.

From time to time, the Company enters into strategic acquisitions in an effort to better service existing customers and to obtain new customers.

Fiscal 2022

On June 22, 2022, Atkore International Inc., a wholly-owned subsidiary of the Company acquired all of the outstanding stock of United Poly Systems, LLC (“United Poly”), for a purchase price of $226,506. United Poly is a manufacturer of high density polyethylene (“HDPE”) pressure pipe and conduit, primarily serving the telecommunications, water infrastructure, renewables and energy markets. The purchase price allocation has not been finalized as the Company is finalizing working capital, inventory, intangible asset, deferred tax asset and liabilities and fixed asset fair values.

On May 19, 2022, Allied Tube and Conduit Corporation, wholly-owned subsidiary of the Company acquired the assets of Talon Products, LLC (“Talon”), for a purchase price of $4,193. Talon is a manufacturer of non-metallic, injection molded cable cleats, primarily serving the power distribution markets. The purchase price allocation has not been finalized as the Company is finalizing working capital and intangible asset fair values.

On December 21, 2021, Atkore HDPE, LLC and Allied Tube and Conduit Corporation, wholly-owned subsidiaries of the Company, acquired the assets of Four Star Industries LLC (“Four Star”), for a purchase price of $23,195. Four Star is a manufacturer of high density polyethylene (HDPE) conduit, primarily serving the telecommunications, utility, infrastructure and datacom markets. The Company finalized the purchase price allocation of Four Star in the third quarter of fiscal 2022.

On December 20, 2021, Columbia-MBF Inc., a wholly-owned subsidiary of the Company acquired all of the outstanding stock of Sasco Tubes & Roll Forming Inc. (“Sasco”), for a purchase price of $16,184, of which $13,320 was paid at closing and additional purchase price payable of $2,864 was accrued. Sasco is a Canadian manufacturer of metal framing and related products serving the electrical, mechanical, construction and solar industries. The Company finalized the purchase price allocation of Sasco in the third quarter of fiscal 2022.

The acquisitions in fiscal 2022 were funded using cash-on-hand. The Company incurred approximately $3,274 in acquisition-related expenses for these acquisitions, which were recorded as a component of selling, general and administrative expenses.

The purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values. The following table summarizes the Level 3 fair values assigned to the net assets acquired and liabilities assumed as of the acquisition date for fiscal 2022:

(in thousands)	United Poly		Other		Total
Fair value of consideration transferred:
Cash consideration	$	226,506	$	40,306	$	266,812
Purchase price payable	—		3,266		3,266
Total consideration transferred	$	226,506	$	43,572	$	270,078
Fair value of assets acquired and liabilities assumed:

Accounts receivable	23,679		5,684		29,363
Inventories	13,266		4,821		18,087
Intangible assets	118,670		19,640		138,310
Fixed assets	14,091		2,784		16,875

Other	(103)		(129)		(232)
Net assets acquired	156,925		26,730		183,655
Excess purchase price attributed to goodwill acquired	$	69,581	$	16,842	$	86,423

The Company estimates $11.7 million of the goodwill recognized on the United Poly acquisition is deductible for tax purposes. Goodwill recognized from the acquisitions in fiscal 2022 consists largely of the synergies and economies of scale from integrating this company with existing businesses.

The following table summarizes the fair value of intangible assets as of the acquisition date:

	United Poly			Other
(in thousands)	Fair Value		Weighted Average Useful Life (Years)	Fair Value		Weighted Average Useful Life (Years)
Customer relationships	$	96,100	11	$	16,720	10
Other	22,570		8	2,920		8
Total intangible assets	$	118,670		$	19,640

The following table presents unaudited pro forma results of operations for the Company and all companies acquired in fiscal 2022 as if those acquisitions had occurred on October 1, 2020. The results presented below are for the three and nine months ended: 

	Three months ended				Nine months ended
(in thousands)	June 24, 2022		June 25, 2021		June 24, 2022		June 25, 2021
Pro forma net sales	$	1,096,866	$	883,980	$	2,992,265	$	2,068,169
Pro forma net income	256,356		175,107		696,012		378,795

The pro forma condensed financial information is presented for illustrative purposes only and does not indicate the actual financial results of the Company if the closing of the acquisitions in the current year had been completed on October 1, 2020, nor is it indicative of the results of operations in future periods. Included in the unaudited pro forma financial information for the three and nine months ended June 24, 2022 and June 25, 2021 were pro forma adjustments to reflect the results of operations of the acquisitions in the current year as though those acquisitions were completed as of the beginning of October 1, 2020, as well as the impact of amortizing certain acquisition accounting adjustments such as amortizable intangible assets. The pro forma financial information neither indicates the impact of possible business model changes nor considers any potential impact of current market conditions, expense efficiencies or other factors.

Net sales and net income of the acquired companies are included in the consolidated statement of operations for the quarter and nine months ended June 24, 2022 for the post-acquisition period.

Fiscal 2021

On February 24, 2021, Atkore Southwest, LLC, a wholly-owned subsidiary of the Company acquired the assets of FRE Composites USA Inc. and separately the Company acquired all of the outstanding stock of FRE Composites Inc., collectively described as FRE Composites Group (“FRE Composites”), for a purchase price of $36,993, net of cash received. FRE Composites is a leading manufacturer of fiberglass conduit for the electrical and industrial market. The purchase price was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values.

On October 22, 2020, Atkore Plastics Southeast, LLC, a wholly-owned subsidiary of the Company acquired the assets of Queen City Plastics, Inc. (“Queen City Plastics”), a leading manufacturer of PVC conduit, elbows and fittings for the electrical market. The purchase price was allocated to tangible assets acquired and liabilities assumed based on their fair values. The purchase price of $6,214 was deemed immaterial to the Company.

The purchase price for FRE Composites, which was finalized during the fourth quarter of fiscal 2021, was allocated to tangible and intangible assets acquired and liabilities assumed, based on their fair values.

The acquisitions in fiscal 2021 were funded using cash-on-hand. The Company incurred approximately $646 in acquisition-related expenses for these acquisitions, which were recorded as a component of selling, general and administrative expenses.

The following table summarizes the Level 3 fair values assigned to the net assets acquired and liabilities assumed as of the acquisition date for fiscal 2021:

(in thousands)	FRE Composites
Fair value of consideration transferred:
Cash consideration	$	36,993
Fair value of assets acquired and liabilities assumed:
Cash	437
Accounts receivable	2,163
Inventories	3,355
Intangible assets	18,300
Fixed assets	8,509
Accounts payable	(1,186)
Income taxes	(4,293)
Other	(240)
Net assets acquired	27,045
Excess purchase price attributed to goodwill acquired	$	9,948

The Company estimates $1.6 million of the goodwill recognized on the FRE acquisition is deductible for tax purposes. Goodwill recognized from the acquisitions in fiscal 2021 consists largely of the synergies and economies of scale from integrating this company with existing businesses.

The following table summarizes the fair value of intangible assets as of the acquisition date:

	FRE Composites
(in thousands)	Fair Value		Weighted Average Useful Life (Years)
Customer relationships	$	14,700	12
Other	3,600		6
Total intangible assets	$	18,300

Net sales and net income of both the above acquisitions are included in the condensed consolidated statement of operations for the post-acquisition periods. Due to the immaterial nature of these acquisitions, both individually and in the aggregate, the Company did not include the full year pro forma results of operations for the acquisition year or previous years.

INCOME TAXES

6. INCOME TAXES    

For the three months ended June 24, 2022 and June 25, 2021, the Company’s effective tax rate attributable to income before income taxes was 25.7% and 26.0%, respectively. For the three months ended June 24, 2022 and June 25, 2021, the Company’s income tax expense was $88,041 and $61,654 respectively. The decrease in the current period effective tax rate was primarily driven by the prior year one-time tax expense from the deferred remeasurement of our UK subsidiaries due to the enactment of the Finance Act of 2021 which, among other things, changed the UK corporate tax rate from 19% to 25%.

For the nine months ended June 24, 2022 and June 25, 2021, the Company’s effective tax rate attributable to income before income taxes was 24.4% and 24.8%, respectively. For the nine months ended June 24, 2022 and June 25, 2021, the Company’s income tax expense was $223,630 and $126,922 respectively. The decrease in the current period effective tax rate was driven by an increase in the excess tax benefit associated with stock compensation.

A valuation allowance has been recorded against certain net operating losses in certain foreign jurisdictions. A valuation allowance is recorded when it is determined to be more likely than not that these assets will not be fully realized in the foreseeable future. The realization of deferred tax assets is dependent upon whether the Company can generate future taxable income in the appropriate character and jurisdiction to utilize the assets. The amount of the deferred tax assets considered realizable is subject to adjustment in future periods.

The Company recognizes the benefits of uncertain tax positions taken or expected to be taken in tax returns in the provision for income taxes only for those positions that we have determined are more likely than not to be realized upon examination. We record interest and penalties related to unrecognized tax benefits as a component of income tax expense. During the nine months ended June 24, 2022, the balance of unrecognized tax benefits decreased by $1,893 primarily due to the resolution of a state tax matter.

For the nine months ended June 24, 2022, the Company made no additional provision for U.S. or non-U.S. income taxes for unrecognized deferred tax liabilities for temporary differences related to basis differences in investments in subsidiaries, as the investments are essentially permanent in duration.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

7. EARNINGS PER SHARE

The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all of the net earnings for the period had been distributed. The Company’s participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders.

Basic earnings per common share excludes dilution and is calculated by dividing the net earnings allocated to common stock by the weighted-average number of common stock outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common stock by the weighted-average number of shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

The following table sets forth the computation of basic and diluted earnings per share:

There were no anti-dilutive options outstanding during the three months ended June 24, 2022 and June 25, 2021. Additionally, there were no anti-dilutive options outstanding during the nine months ended June 24, 2022 and June 25, 2021.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

13. FAIR VALUE MEASUREMENTS

Certain assets and liabilities are required to be recorded at fair value on a recurring basis.

The Company uses a forward currency contract to hedge the effects of foreign exchange relating to one of the Company’s intercompany balances denominated in a foreign currency. This derivative instrument is not formally designated as a hedge by the Company and the remaining term of the instrument is two months. Short-term forward currency contracts are recorded in either other current assets or other current liabilities and long-term forward currency contracts are recorded in either other long-term assets or other long-term liabilities in the condensed consolidated balance sheet. The fair value gains and losses are included in other income, net within the condensed consolidated statements of operations. See Note 5, “Other Income, net” for further detail.

The total notional amounts of undesignated forward currency contracts were £30.6 million and £37.4 million as of June 24, 2022 and September 30, 2021, respectively. Cash flows associated with derivative financial instruments are recognized in the operating section of the condensed consolidated statements of cash flows. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The following table presents the Company’s assets and liabilities measured at fair value:

	June 24, 2022				September 30, 2021
(in thousands)	Level 1		Level 2		Level 1		Level 2
Assets
Cash equivalents	$	97,476	$	—	$	489,987	$	—
Forward currency contracts	—		3,381		—		127
Liabilities
Forward currency contracts	—		472		—		183

The Company’s remaining financial instruments consist primarily of cash, accounts receivable and accounts payable whose carrying value approximate their fair value due to their short-term nature.

The estimated fair value of financial instruments not carried at fair value in the condensed consolidated balance sheets were as follows:

	June 24, 2022				September 30, 2021
(in thousands)	Carrying Value		Fair Value		Carrying Value		Fair Value
Senior Secured Term Loan Facility due May 26, 2028	$	373,000	$	369,852	$	373,000	$	371,486
Senior Notes due June 2031	400,000		340,000		400,000		415,828
Total Debt	$	773,000	$	709,852	$	773,000	$	787,314

In determining the approximate fair value of its long-term debt, the Company used the trading values among financial institutions, and these values fall within Level 2 of the fair value hierarchy. The carrying value of the ABL Credit Facility approximates fair value due to it being a market-linked variable rate debt.

COMMITMENTS AND CONTINGENCIES

14. COMMITMENTS AND CONTINGENCIES

The Company has obligations related to commitments to purchase certain goods. As of June 24, 2022, such obligations were $238,059 for the rest of fiscal year 2022 and $12,334 for fiscal year 2023 and beyond. These amounts represent open purchase orders for materials used in production.

Insurable Liabilities — The Company maintains policies with various insurance companies for its workers’ compensation, product, property, general, auto, and executive liability risks. The insurance policies that the Company maintains have various retention levels and excess coverage limits. The establishment and update of liabilities for unpaid claims, including claims incurred but not reported, is based on management's estimate as a result of the assessment by the Company's claim administrator of each claim and an independent actuarial valuation of the nature and severity of total claims. The Company utilizes a third-party claims administrator to pay claims, track and evaluate actual claims experience, and ensure consistency in the data used in the actuarial valuation.

Legal Contingencies — Historically, a number of lawsuits have been filed against the Company and the Company has also received other claim demand letters alleging that the Company's anti-microbial coated steel sprinkler pipe, which the Company has not manufactured or sold for several years, is incompatible with chlorinated polyvinyl chloride and caused stress cracking in such pipe manufactured by third parties when installed together in the same sprinkler system, which the Company refers to collectively as the “Special Products Claims.” Tyco International Ltd. (“Tyco”), now Johnson Controls, Inc. (“JCI”), has a contractual obligation to indemnify the Company in respect of all remaining and future claims of incompatibility between the Company's antimicrobial coated steel sprinkler pipe and CPVC pipe used in the same sprinkler system. When Special Products Claims arise, JCI has defended and indemnified the Company as required.

At this time, the Company does not expect the outcome of the Special Products Claims proceedings, either individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations or cash flows, and the Company believes that its reserves are adequate for all remaining contingencies for Special Products Claims.

In addition to the matters discussed above, from time to time, the Company is subject to a number of disputes, administrative proceedings and other claims arising out of the ordinary conduct of the Company’s business. These matters generally relate to disputes arising out of the use or installation of the Company’s products, product liability litigation, contract disputes, patent infringement accusations, employment matters, personal injury claims and similar matters. On the basis of information currently available to the Company, it does not believe that existing proceedings and claims will have a material adverse effect on its business, financial condition, results of operations or cash flows. However, litigation is unpredictable, and the Company could incur judgments or enter into settlements for current or future claims that could adversely affect its business, financial condition, results of operations or cash flows.

15. GUARANTEES

The Company had outstanding letters of credit totaling $12,095 supporting workers’ compensation and general liability insurance policies as of June 24, 2022. The Company also had surety bonds primarily related to performance guarantees on supply agreements and construction contracts, and payment of duties and taxes totaling $30,039 as of June 24, 2022.

In disposing of assets or businesses, the Company often provides representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal fees related to periods prior to disposition. The Company does not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, the Company has no reason to believe that these uncertainties would have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

In the normal course of business, the Company is liable for product performance and contract completion. In the opinion of management, such obligations will not have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

Segment Reporting [Abstract]

SEGMENT INFORMATION

16. SEGMENT INFORMATION

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, restructuring costs and transaction costs.

Intersegment transactions primarily consist of product sales at designated transfer prices on an arm’s-length basis. Gross profit earned and reported within the segment is eliminated in the Company’s consolidated results. Certain manufacturing and distribution expenses are allocated between the segments on a pro rata basis due to the shared nature of activities. Recorded amounts represent a proportional amount of the quantity of product produced for each segment. Certain assets, such as machinery and equipment and facilities, are not allocated to each segment despite serving both segments. These shared assets are reported within the Safety & Infrastructure segment. The Company allocates certain corporate operating expenses that directly benefit our operating segments, such as insurance and information technology, on a basis that reasonably approximates an estimate of the use of these services.

Basis of Presentation

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s accounting policies and on the same basis as those financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended September 30, 2021, filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 18, 2021, and should be read in conjunction with those consolidated financial statements and the notes thereto. Certain information and disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited condensed consolidated financial statements include the assets and liabilities used in operating the Company’s business. All intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or disposed of are included in the unaudited condensed consolidated financial statements from the effective date of acquisition or up to the date of disposal.

These statements include all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. The results reported in these unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year.

Fiscal Periods

Fiscal Periods — The Company has a fiscal year that ends on September 30. The Company’s fiscal quarters typically end on the last Friday in December, March and June as it follows a 4-5-4 calendar.

Use of Estimates

Use of Estimates — The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclose contingent assets and liabilities at the date of the condensed consolidated financial statements and report the associated amounts of revenues and expenses. Actual results could differ materially from these estimates.
