Notes to Consolidated Financial Statements

1. Basis of Presentation

The accompanying unaudited consolidated financial statements and related notes of Tetra Tech, Inc. (“we,” “us,” “our” or "Tetra Tech") have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and, therefore, should be read in conjunction with the audited consolidated financial statements and the notes contained in our Annual Report on Form 10-K for the fiscal year ended October ~~3, 2021.~~2, 2022.

These financial statements reflect all normal recurring adjustments that are considered necessary for a fair statement of our financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for any interim period are not necessarily indicative of results for the full fiscal year or for future ~~years~~fiscal yea.

~~Beginning in fiscal 2022, we aligned our operations to better serve our clients and markets, and created a new High Performance Buildings~~ ~~("HPB")~~ ~~division in our Commercial/International Services Group ("CIG") reportable segment. As a result, we transferred some related operations in our~~ ~~Government Services Group ("GSG") reportable segment to our CIG reportable segment. Prior~~rs. Certain prior year amounts ~~for reportable segments~~ have been reclassified to conform to the current year presentation.

2. Recent Accounting Pronouncements

In ~~December 2019,~~November 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to general principles in Topic 740 and amending certain existing guidance for clarity~~. We adopted this guidance in the first quarter of fiscal 2022, and the adoption did not have an impact on our consolidated financial statements.~~

~~In May 2020, the Securities and Exchange Commission issued guidance amending certain financial~~ disclosures about acquired and disposed businesses. The amendments are designed to assist registrants in making more meaningful determinations of whether a subsidiary or an acquired or disposed business is significant, and to improve the related disclosure requirements. ~~We adopted this guidance in the first quarter of fiscal 2022, and the adoption did not have an impact on our consolidated financial statements.~~

In October 2021, the FASB issued ASU 2021-08, which requires the recognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification Topic 606, "Revenue from Contracts with Customers" ("ASC 606"). Considerations to determine the amount of contract assets and contract liabilities to record at the acquisition date include the terms of the acquired contract, such as timing of payment, identification of each performance obligation in the contract and allocation of the contract transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception. ASU 2021-08 is effective for us beginning in the first quarter of fiscal 2023. ASU 2021-08 should be applied prospectively for acquisitions occurring on or after the effective date of the amendments. Early adoption of the proposed amendments would be permitted, including adoption in an interim period. We are currently assessing the impact this standard will have on our consolidated financial statements.

~~In November 2021, the FASB~~ issued ASU 2021-10, Government Assistance (Topic 832), which requires annual disclosures for transactions with a government authority that are accounted for by applying a grant or contribution model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity's financial statements. ASU 2021-10 iswas effective for us beginning in the first quarter of fiscal 2023.

In fiscal 2020, the Canadian federal government implemented the Canadian Emergency Wage Subsidy ("CEWS") program in response to the negative impact of the coronavirus disease 2019 ("COVID-19") pandemic on businesses operating in Canada. Our Canadian legal entities qualified for and applied for these CEWS cash benefits to partially offset the impacts of revenue reductions and on-going staffing costs. The $26.0 million total received was initially recorded in "Other current liabilities" until all potential amendments to the qualification criteria, including some that were proposed with retroactive application, were finalized in fiscal 2022. As there are no further contingencies, beginning in fiscal 2023, ~~with early adoption permitted. This guidance should~~the amounts received will be ~~applied prospectively~~distributed to all ~~transactions that are reflected~~Canadian employees. We expect to distribute approximately $9 million in the ~~financial statements~~next twelve months. Accordingly, this amount was reclassified from "Other current liabilities" to "Accrued compensation" on our consolidated balance sheet at ~~the date of initial application and~~October 2, 2022. The remaining $17.0 million, which we expect to ~~new transactions that are entered into after that date, or retrospectively.~~ distribute beyond one year, was reclassified to "Other non-current liabilities". We do not expect ~~the adoption of this guidance~~there will be any related impact to our operating income, and we have ~~a material impact on our consolidated financial statements.~~no outstanding applications for further government assistance.

3. Revenue and Contract Balances

Other than the U.S. federal government, no single client accounted for more than 10% of our revenue for the three and six months ended April 2, 2023 and April 3, ~~2022 and March 28, 2021.~~2022.

Contract Assets and Contract Liabilities

We invoice customers based on the contractual terms of each contract. However, the timing of revenue recognition may differ from the timing of invoice issuance.

Contract assets represent revenue recognized in excess of the amounts for which we have the contractual right to bill our customers. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones or completion of a contract. In addition, many of our time and materials arrangements are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Contract retentions, included in contract assets, represent amounts withheld by clients until certain conditions are met or the project is completed, which may extend beyond one year.

Contract liabilities consist of billings in excess of revenue recognized. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and increase as billings in advance of revenue recognition occur. Contract assets and liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. There were no substantial non-current contract assets or liabilities for the periods presented. Net contract assets/liabilities consisted of the ~~following:~~following (in thousands):

(1) Includes ~~$18.8~~$13.0 million and ~~$12.2~~$23.3 million of contract retentions ~~as of~~at April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, respectively.

In the first ~~halves~~half of fiscal ~~2022~~2023 and ~~2021,~~2022, we recognized revenue of approximately $121 million and $93 million, ~~and $90 million~~, respectively, from the amounts included in the contract liability balances at the end of fiscal 2022 and 2021, ~~and 2020,~~ respectively.

We recognize revenue primarily using the cost-to-cost measure of progress method to estimate progress towards completion. Changes in those estimates could result in the recognition of cumulative catch-up adjustments to the contract’s inception-to-date revenue, costs and profit in the period in which such changes are made. As a ~~result,~~result, we recognized net

favorable revenue and operating income adjustments of $4.0 million and $5.0 million in the first ~~half~~halves of fiscal 2023 and 2022, ~~and $1.1 million in the first half of fiscal 2021.~~respectively.

Changes in revenue and cost estimates could also result in a projected loss, determined at the contract level, which would be recorded immediately in earnings. ~~As of~~At April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, our consolidated balance sheets included liabilities for anticipated losses of ~~$11.6~~$7.8 million and ~~$12.7~~$10.0 million, respectively. The estimated cost to complete these related contracts ~~as of~~at April ~~3, 2022~~2, 2023 and October ~~3, 2021~~2, 2022 was approximately ~~$88~~$67 million and ~~$104~~$80 million, respectively.

Billed accounts receivable represent amounts billed to clients that have not been collected. Unbilled accounts receivable, which represent an unconditional right to payment subject only to the passage of time, include unbilled amounts typically resulting from revenue recognized but not yet billed pursuant to contract terms or billed after the period end date. Substantially all of our unbilled receivables at April ~~3, 2022~~2, 2023 are expected to be billed and collected within 12 months. The allowance for doubtful accounts represents amounts that are expected to become uncollectible or unrealizable in the future. We determine an estimated allowance for uncollectible accounts based on management's consideration of trends in the actual and forecasted credit quality of our clients, including delinquency and payment history; type of client, such as a government agency or a commercial sector client; and general economic and industry ~~conditions, including the potential impacts of the coronavirus disease 2019 ("COVID-19") pandemic, that may affect our clients' ability to pay.~~

~~Total accounts receivable at April 3, 2022 and October 3, 2021 included approximately~~ ~~$11 million f~~or each period, related to claims, including requests for equitable adjustment, on contracts that provide for price redetermination. This amount relates to a single claim in our RCM reportable segment. ~~In May 2022, we received a cash settlement for the $11 million claim in our RCM segment, which will result in an immaterial gain in the third quarter of fiscal 2022.~~ Claims are amounts in excess of agreed contract prices that we seek to collect from our clients or other third parties for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved as to both scope and price, or other causes of unanticipated additional costs. Factors considered in determining whether revenue associated with claims (including change orders in dispute and unapproved change orders in regards to both scope and price) should be recognized include the following: (a) the contract or other evidence provides a legal basis for the claim, (b) additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in our performance, (c) claim-related costs are identifiable and considered reasonable in view of the work performed, and (d) evidence supporting the claim is objective and verifiable. This can lead to a situation in which costs are recognized in one period and revenue is recognized in a subsequent period when a client agreement is obtained, or a claims resolution occurs.

~~We regularly evaluate all unsettled claim amounts and record appropriate adjustments to revenue when it is probable that the claim will result in a different contract value than the amount previously estimated.In the first halves of fiscal 2022 and fiscal 2021, we recorded no gains or losses related to claims.~~conditions.

Other than the U.S. federal government, no single client accounted for more than 10% of our accounts receivable at April ~~3, 2022~~2, 2023 and October ~~3, 2021.~~2, 2022.

Our RUPO represents a measure of the total dollar value of work to be performed on contracts awarded and in progress. We h~~ad $3.6~~had $4.2 billion of RUPO ~~as of~~at April ~~3, 2022.~~2, 2023. RUPO increases with awards from new contracts or additions on existing contracts, and decreases as work is performed and revenue is recognized on existing contracts. RUPO may also decrease when projects are canceled or modified in scope. We include a contract within our RUPO when the contract is awarded and an agreement on contract terms has been reached.

We expect to satisfy our RUPO ~~as of~~at April ~~3, 2022~~2, 2023 over the following ~~periods:~~periods (in thousands):


	Amount
	~~(in thousands)~~
Within 12 months	$	~~2,171,878~~2,879,867
Beyond	~~1,418,218~~1,356,085
Total	$	~~3,590,096~~4,235,952

Although RUPO reflects business that is considered to be firm, cancellations, deferrals or scope adjustments may occur. RUPO is adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate. Our operations and maintenance contracts can generally be terminated by the clients without a substantive financial penalty. Therefore, the remaining performance obligations on such contracts are limited to the notice period required for the termination (usually 30, 60, or 90 days).

4. Acquisitions

On September 23, 2022, we made an all cash offer to acquire all of the outstanding shares of RPS Group plc ("RPS"), a publicly traded company on the London Stock Exchange for 222 pence per share, through a scheme of arrangement, which was unanimously recommended by RPS' Board of Directors. On November 3, 2022, RPS' shareholders approved the scheme of arrangement.On January 19, 2023, the court-sanctioned scheme of arrangement to purchase RPS was approved, and we completed the acquisition on January 23, 2023. RPS employs approximately 5,000 associates in the United Kingdom, Europe, Asia Pacific and North America, delivering high-end solutions, especially in energy transformation, water and program management for government and commercial clients. Substantially all of RPS is included in our CIG segment.

The total purchase price of RPS was approximately £633 million ($784 million). In the second quarter and first half of fiscal 2023, we incurred $19.9 million and $23.7 million, respectively, related to acquisition and integration costs primarily for professional fees, substantially all of which were paid as of the end of the second quarter of fiscal 2023. On January 23, 2023, we also settled a foreign exchange forward contract that was integral to our plan to finance the RPS acquisition developed in the fourth quarter of fiscal 2022. The cash gain of $109.3 million did not qualify for hedge accounting. As a result, the gain was recognized as non-operating income over the life of the contract and not included in the purchase price allocation below. However, the cash proceeds of $109.3 million economically reduced the purchase price for the shares of RPS to approximately $675 million. This forward contract is explained further in Note 15, "Derivative Financial Instruments".

The table below represents the preliminary purchase price allocation for RPS based on estimates, assumptions, valuations and other analyses as of January 23, 2023, that has not been finalized in order to make a definitive allocation. The purchase consideration, excluding the aforementioned forward contract gain, is allocated to the tangible and intangible assets, and liabilities of RPS based on their estimated fair values, with any excess purchase consideration allocated to goodwill as follows (in thousands):

Supplemental Pro Forma Information (Unaudited)

Following are the supplemental consolidated financial results of Tetra Tech and RPS on an unaudited pro forma basis, as if the RPS acquisition had been consummated as of the beginning of fiscal 2022 (in thousands):


	Three Months Ended				Six Months Ended
	April 2, 2023		April 3, 2022		April 2, 2023		April 3, 2022

Revenue	$	1,203,538	$	1,040,645	$	2,310,839	$	2,074,544
Net Income including noncontrolling interests	$	40,200	$	36,104	$	103,901	$	59,043

For the period from January 23, 2023 through April 2, 2023, RPS had revenue of $169.5 million. RPS' net income, including interest expense, for this period was a loss of $2.0 million, or $0.03 per share, before intangible amortization. Intangible amortization for RPS was $7.7 million, or $0.11 per share.

In the second quarter of fiscal 2023, we also acquired Amyx, Inc. (“Amyx”), an enterprise technology services, cybersecurity and management consulting firm. Based in Reston, Virginia, Amyx, with over 500 employees, provides application modernization, cybersecurity, systems engineering, financial management and program management support on over 30 Federal Government programs. Amyx is included in our GSG segment. The total fair value of the purchase price of Amyx was $120.9 million, comprised of a $100.0 million payable in a promissory note issued to the sellers (paid subsequent to closing), $8.7 million of payables related to estimated post-closing adjustments, and $12.2 million for the estimated fair value of contingent earn-out obligations, with a maximum of $25.0 million, based upon the achievement of specified operating income targets in each of the three years following the acquisition date. Amyx was not considered significant to our consolidated financial statements. As a result, no pro forma information has been provided.

In fiscal 2022, we acquired The Integration Group of America ("TIGA"), Piteau Associates (“PAE”), and two other financially immaterial acquisitions.TIGA is based in Spring, Texas and is an industry leader in process automation and system integration solutions, including customized software and platform (SaaS/PaaS) applications, advanced data analytics, cloud data integration and platform virtualization. PAE is based in Vancouver, British ~~Columbia. PAE~~Columbia and is a global leader in sustainable natural resource analytics including hydrologic numerical modeling and dewatering system design. PAE is part of our ~~Commercial/International Services Group (“CIG”) segment. During~~CIG segment, and TIGA and the ~~first half of fiscal 2022, we completed~~ other financially immaterial acquisitions ~~which~~ are part of our GSG segment. The total fair value of the purchase price offor all four acquisitions ~~during the first half of fiscal 2022~~ was ~~$70.0~~$88.3 million. This amount is comprised of $44.0 million in initial cash payments made to the sellers, ~~$1.8~~$2.5 million of ~~payables~~receivables (net) related to estimated post-closing adjustments for the net assets acquired, $15.5 million payable in a promissory note issued to the sellers along with related transaction expenses of the sellers (which were subsequently paid in July 2022), and ~~$24.2~~$31.3 million for the estimated fair value of contingent earn-out obligations, with a maximum of ~~$35.5 million, based upon the achievement of specified operating income targets in each of the five years following the acquisitions.~~

In fiscal 2021, we acquired Coanda Research and Development Corporation ("CRD"), The Kaizen Company (“KZN”), IBRA-RMAC Automation Solutions (“IRM”), and the partnership interests of Hoare Lea, LLP and Subsidiaries ("HLE"). CRD is based in Burnaby, British Columbia and provides world-class expertise in computational fluid dynamics and utilizes industry-leading capabilities to solve complex engineering science problems for commercial customers, across a broad range of industries. KZN is based in Washington, DC and provides international development advisory and management consulting services offering a suite of innovative tools that support advanced solutions in health, education, governance, peace and stability, and sustainable economic growth. IRM is based in San Diego, California, and provides digital water transformation consulting services and an innovative suite of tools to address complex water system modernization challenges. HLE is a leader in sustainable engineering design based in Bristol, United Kingdom. It was established in 1862 and is an award-winning high-end consultancy firm in the United Kingdom, with more than 900 employees, providing innovative solutions to complex engineering and design challenges for sustainable infrastructure and high performance buildings. CRD and HLE are part of our CIG segment, and KZN and IRM are part of our GSG segment. The total fair value of the purchase price for these acquisitions was $151.7 million. This amount was comprised of $101.4 million in initial cash payments made to the sellers, and $50.3 million for the estimated fair value of contingent earn-out obligations, with a maximum of $74.0$47.0 million, based upon the achievement of specified operating income targets in each of the three to ~~four~~five years following the acquisitions.These acquisitions were not considered significant, individually or in the aggregate, to our consolidated financial statements. As a result, no pro forma information has been provided.

The majority of the goodwill from the fiscal 2023 acquisitions is not deductible for tax purposes, while the majority of the goodwill from the fiscal 2022 acquisitions is deductible for tax purposes. The results of fiscal 2022 and 2023 acquisitions were included in our consolidated financial statements beginning on the respective closing dates.

Goodwill additions resulting from the fiscal 2023 business combinations are primarily attributable to the significant technical expertise residing in embedded workforces that are sought out by clients, synergies expected to arise after the acquisitions in the areas of enterprise technology services, data management, energy transformation, water, program management, and data analytics and the long-standing reputations of RPS and Amyx. These acquisitions further expand and complement our market-leading positions in water, renewable energy and sustainable infrastructure; enhanced by a combined suite of differentiated data analytics and digital technologies, and expansion into existing and new geographies. Our fiscal 2022 ~~business combinations~~goodwill additions are primarily attributable to the significant technical expertise residing in embedded workforces that are sought out by clients, long-term management experience, the ~~reputation of PAE in its~~ industry reputations and the synergies expected to arise after the acquisitions in the areas of data management, digitization, modeling, water and natural resources. The fiscal 2021 goodwill additions represent the significant technical expertise residing in embedded workforces that are sought out by clients and the long-standing reputation of HLE. In addition, theseThese acquired capabilities, when combined with our existing global consulting and engineering business, result in opportunities that allow us to provide services under contracts that could not have been pursued individually by either us or the acquired companies. The results of these acquisitions were included in our consolidated financial statements from their respective closing dates. These acquisitions were not considered material, individually or in the aggregate, to our consolidated financial statements. As a result, no pro forma information has been provided.

These consist of client relations, backlog and trade ~~names with lives ranging from~~ ~~three~~ ~~to five years.~~names. For detailed information regarding our intangible assets, see Note 5, “Goodwill and Intangible Assets”.

Most of our acquisition agreements include contingent earn-out agreements, which are generally based on the achievement of future operating income thresholds. The contingent earn-out arrangements are based on our valuations of the acquired companies and reduce the risk of overpaying for acquisitions if the projected financial results are not achieved. The fair values of any earn-out arrangements are included as part of the purchase price of the acquired companies on their respective

acquisition dates. For each transaction, we estimate the fair value of contingent earn-out payments as part of the initial purchase price and record the estimated fair value of contingent consideration as a liability in “Current contingent earn-out liabilities” and ~~“Long-term~~“Non-current contingent earn-out liabilities” on the consolidated balance sheets. We consider several factors when determining that contingent earn-out liabilities are part of the purchase price, including the following: (1) the valuation of our acquisitions is not supported solely by the initial consideration paid, and the contingent earn-out formula is a critical and material component of the valuation approach to determining the purchase price; and (2) the former owners of acquired companies that remain as key employees receive compensation other than contingent earn-out payments at a reasonable level compared with the compensation of our other key employees. The contingent earn-out payments are not affected by employment termination.

We measure our contingent earn-out liabilities at fair value on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. We use a probability-weighted discounted income approach as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are operating income projections over the earn-out period (generally three to five years), and the probability outcome percentages we assign to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the contingent earn-out liability on the acquisition date is reflected as cash used in financing activities in our consolidated statements of cash flows. Any amount paid in excess of the contingent earn-out liability on the acquisition date is reflected as cash used in operating activities in our consolidated statements of cash flows.

We review and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the initial estimates. Changes in the estimated fair value of our contingent earn-out liabilities related to the time component of the present value calculation are reported in interest expense. Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income. InFor the first half of fiscal ~~2022,~~2023, we evaluated our estimates for contingent consideration liabilities for the remaining earn-out periods for each individual acquisition, which included a review of their financial results to-date, the status of ongoing projects in their RUPO, and the inventory of prospective new contract awards. ~~In addition, we considered the potential impact of the global economic disruption due to the COVID-19 pandemic on our operating income projections over the various earn-out peri~~

~~ods.~~

During the first ~~halves~~half of fiscal 2023, we recorded adjustments to our contingent earn-out liabilities and reported a related net loss in operating income of $8.5 million (largely in the second quarter). The net loss primarily resulted from increased valuations of the contingent consideration liabilities for our prior acquisitions of Segue Technologies, Inc. (SEG), Hoare Lea, LLP (HLE) and TIGA reflecting financial performance that exceeded our previous expectations.

For the second quarter and first half of fiscal 2022, ~~and 2021, the total~~ we had no material adjustments to our contingent earn-out liabilities in operating ~~income were immaterial.~~income.

At April ~~3, 2022,~~2, 2023, there was a total potential maximum of ~~$139.6~~$143.9 million of outstanding contingent consideration related to acquisitions. Of this amount, ~~$79.1~~$88.1 million was estimated as the fair value and accrued on our consolidated balance ~~sheet.~~sheet at April 2, 2023.

~~Our goodwill balances reflect the goodwill reallocation related to the creation of our new HPB division on the first day of fiscal 2022, which included a transfer of some related operations~~
~~in our GSG reportable segment to our CIG reportable segment.~~

The foreign currency translation adjustments resulted from our foreign subsidiaries with functional currencies that are

different than our reporting currency. These goodwill amounts are presented net of reductions from historical impairment adjustments. The gross amounts o~~f goodwill~~ for GSG were ~~$528.1~~$644.9 million and ~~$556.1~~$536.8 million at April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, respectively, excluding accumulated impairment of $17.7 million at each date. The gross amounts of goodwill for CIG were ~~$769.7~~$1,350.7 million and ~~$691.6~~$712.8 million at April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, respectively, excluding accumulated impairment of $121.5 million at each date.

We perform our annual goodwill impairment review at the beginning of our fiscal fourth quarter. Our most recent annual review at ~~June 28, 2021~~July 4, 2022 (i.e. the first day of our fourth quarter in fiscal ~~2021)~~2022) indicated that we had no impairment of goodwill, and all of our reporting units had estimated fair values that were in excess of their carrying values, including goodwill. ~~As of June 28, 2021,~~At July 4, 2022, and after the reallocation of goodwill on the first day of fiscal 2022, we had no reporting units that had estimated fair values that exceeded their carrying ~~values~~values by less than ~~150%~~165%.

We also regularly evaluate whether events and circumstances have occurred that may indicate a potential change in the recoverability of goodwill. We perform interim goodwill impairment reviews between our annual reviews if certain events and circumstances have occurred, such as a deterioration in general economic conditions; an increase in the competitive environment; a change in management, key personnel, strategy or customers; negative or declining cash flows; or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods. Although we believe that our estimates of fair value for these reporting units are reasonable, if financial performance for these reporting units falls significantly below our expectations or market prices for similar business decline, the goodwill for these reporting units could become impaired.

7. Stock Repurchase and Dividends

On October 5, 2021, ~~the~~our Board of Directors authorized a new stock repurchase program under which we could repurchase up to $400 million of our common stock ~~in addition to the~~ ~~$147.8 million remaining under the previous stock repurchase program at~~ ~~October 3, 2021~~. InWe did not repurchase any shares of our common stock in the first half of fiscal ~~2022, we repurchased and settled 618,236 shares with an average price of $161.75 per share for a total cost of $100.0 million in the open market.~~2023.

8. Leases

Our operating leases are primarily for corporate and project office spaces. To a much lesser extent, we have operating leases for vehicles and equipment. Our operating leases have remaining lease terms of one month to ~~twelve~~ten years, some of which may include options to extend the leases for up to five years.

We determine if an arrangement is a lease at inception. Operating leases are included in "Right-of-use assets, operating ~~lease right-of-use ("ROU") assets and current and long-term operating~~leases", "Short-term lease liabilities, operating leases" and "Long-term lease liabilities, operating leases" in the consolidated balance sheets. Our finance leases are primarily for certain information technology equipment. The related ROU assets and lease liabilities were immaterial, and are included in "Property and equipment, net", "Other current liabilities" and "Other long-term liabilities", accordingly, in the consolidated balance sheets at April 3, 2022 and October 3, 2021.immaterial.

~~ROU~~Right-of-use ("ROU") assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, incremental borrowing rates are used based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset at the commencement date also includes any lease payments made to the lessor at or before the commencement date and initial direct costs less lease incentives received. Lease terms may

include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.

9. Stockholders’ Equity and Stock Compensation Plans

We recognize the fair value of our stock-based awards as compensation expense on a straight-line basis over the requisite service period in which the award vests. Stock-based compensation expense for the three and six months ended April ~~3, 2022~~2, 2023 was $7.4 million and $14.6 million, respectively, compared to $6.6 million and $12.4 ~~million, respectively, compared to $5.7 million and $10.6~~ million for the same periods last year. Most of these amounts were included in selling, general and administrative expenses on our consolidated statements of income. In the first half of fiscal ~~2022,~~2023, we awarded ~~41,199~~56,214 performance share units (“PSUs”) to our non-employee directors and executive officers at a fair value of ~~$247.47~~$195.50 per share on the award date. All PSUs are performance-based and vest, if at all, after the conclusion of the three-year performance period. The number of PSUs that ultimately vest is based 50% on the growth in our diluted earnings per share and 50% on our relative total shareholder return over the vesting period. Additionally, we awarded ~~73,729~~100,977 restricted stock units (“RSUs”) to our non-employee directors, executive officers and employees at a fair value of ~~$186.91~~$156.41 per share on the award date. All executive officer and employee RSUs have time-based vesting over a four-year period, and the non-employee director RSUs vest after one year.

10. Earnings per Share (“EPS”)

Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding, less unvested restricted stock for the period. Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding and dilutive potential common shares for the period. Potential common shares include the weighted-average dilutive effects of outstanding stock options and unvested restricted stock using the treasury stock method.

11. Income Taxes

The effective tax rates for the first halves of fiscal 2023 and 2022 were 28.7% and ~~2021 were~~ 21.9% ~~and 19.2%~~, respectively. Income tax expense was reduced by ~~$4.8~~by $1.8 million and ~~$8.0~~$4.8 million of excess tax benefits on share-based payments in the first halves of fiscal 2023 and 2022, respectively. In addition, income tax expense in the first half of fiscal 2023 (all in the second quarter) included non-operating income tax expenses of $6.7 million to recognize the tax liability for foreign earnings, primarily in the U.K. and ~~2021, respectively.~~Australia, that are no longer indefinitely reinvested and to increase the liability for an uncertain tax position. Excluding the impact of the excess tax benefits on share-based payments and the non-operating tax expenses in the second quarter of fiscal 2023, our effective tax rates in the first halves of fiscal 2023 and 2022 were 26.5% and ~~2021 were~~25.0% an~~d 25.8%~~, r~~espectively.~~respectively.

~~As of~~At April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, the liability for income taxes associated with uncertain tax positions was ~~$13.9~~$42.4 million and ~~$14.1~~$10.6 million, respectively. These ~~uncertain tax positions substantially relate to ongoing examinations. It is reasonably possible that these~~ liabilities ~~may~~could materially decrease within the next 12 months as ~~certain~~some related examinations ~~are resolved.~~have commenced. These liabilities represent our current estimates of the additional tax liabilities that we may be assessed when the related audits are concluded. If these audits are resolved in a manner more unfavorable than our current expectations, our additional tax liabilities could be materially higher than the amounts currently recorded resulting in additional tax expense.

On December 28, 2021, the U.S. Department of the Treasury and the Internal Revenue Service released final regulations addressing aspects of the foreign tax credit regime, and represent the third and final regulations that have been issued with respect to the core provisions of the U.S. foreign tax credit regime following the 2017 Tax Cut and Jobs Act. These regulations were primarily effective on March 7, 2022, with certain provisions applicable to prior periods. We do not expect these new regulations to materially impact our consolidated financial statements.

12. Reportable Segments

We manage our operations under 2two reportable segments. Our GSG reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our CIG reportable segment primarily includes activities with U.S. commercial clients and international clients other than development agencies. ~~Additionally, we~~ continue to report the results of the wind-down of our non-core construction activities in the RCM reportable segment. There has been no remaining backlog for RCM since fiscal 2018 as the projects were complete.

GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local) and development agencies worldwide. GSG supports U.S. government civilian and defense agencies with services in water, environment, sustainable infrastructure, information technology and disaster management. GSG also provides engineering design services for U.S. ~~municipal~~based federal and ~~commercial~~municipal clients, especially in water infrastructure, flood protection and solid ~~waste, and high-end sustainable infrastructure designs.~~waste. GSG also leads our support for development agencies worldwide, especially in the United States, United Kingdom and Australia.

CIG primarily provides high-end consulting and engineering services to U.S. commercial clients, and international clients ~~that include both~~inclusive of the commercial and government sectors. CIG supports commercial clients across the Fortune 500, ~~clean~~renewable energy, industrial, high performance buildings and aerospace markets. CIG also provides sustainable infrastructure and related

environmental, engineering and project management services to commercial and local government clients across Canada, in Asia Pacific (primarily Australia and New Zealand), the United Kingdom, as well as Brazil and Chile.

At the beginning of fiscal 2022, we aligned our operations to better serve our clients and markets, and created a new HPB division in our CIG reportable segment. As a result, we transferred some related operations in our GSG reportable segment to our CIG reportable segment. Accordingly, amounts related to our segment reporting for the first quarter and first half of fiscal 2021 have been reclassified to conform to the current year presentation.

Management evaluates the performance of these reportable segments based upon their respective segment operating income before the effect of amortization expense related to acquisitions, and other unallocated corporate expenses. We account for inter-segment revenues and transfers as if they were to third parties; that is, by applying a negotiated fee onto the costs of the services performed. All significant intercompany balances and transactions are eliminated in consolidation. In the second quarter and first half of fiscal 2023, our Corporate segment operating losses included $19.9 million and $23.7 million of acquisition and integration expenses, respectively, as described in Note 4, “Acquisitions”.

13. Fair Value Measurements

The fair value of long-term debt was determined using the present value of future cash flows based on the borrowing rates currently available for debt with similar terms and maturities (Level 2 measurement, as described in “Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the fiscal year ended October ~~3, 2021)~~2, 2022). The carrying value of our long-term debt approximated fair value at April ~~3, 2022~~2, 2023 and October ~~3, 2021.~~2, 2022. At April ~~3, 2022,~~2, 2023, we had ~~borrowings o~~bor~~f $250.0 million outstan~~rowing~~ding~~s of $1.08 billion outstanding under our Amended Credit Agreement, which were primarily used to fund business acquisitions, working capital needs, ~~stock repurchases, dividends,~~and capital ~~expenditures and contingent earn-outs.~~expenditures.

14. Credit Facility

On October 26, 2022, we entered into a Third Amended and Restated Credit Agreement that provides for an additional $500 million senior secured term loan facility (the "New Term Loan Facility") increasing our total borrowing capacity to $1.55 billion.

On January 23, 2023, we drew the entire amount of the New Term Loan Facility to partially finance the RPS acquisition. The remaining purchase price was financed with existing cash on hand and borrowings under the existing Amended

Revolving Credit Facility. The New Term Loan Facility is not subject to any amortization payments of principal and matures on the third anniversary of the RPS acquisition closing date.

On February 18, 2022, we entered into Amendment No. 2 to Second Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that will mature in February 2027. The Amended Credit Agreement is a $750 million senior secured, five-year facility that provides for a $250 million term loan facility (the “Amended Term Loan Facility”) and a $500 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $300 million accordion feature that allows us to increase the Amended Credit Agreement to $1.05 billion subject to lender approval. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Credit Agreement dated ~~as of~~at July 30, 2018; (ii) finance open market repurchases of common stock, acquisitions, and cash dividends and distributions; and (iii) utilize the proceeds for working capital, capital expenditures and other general corporate purposes. The Amended Credit Agreement provides for a reduction in the interest grid for meeting certain sustainability targets related to the (i) reduction of greenhouse gas emissions through the Company’s projects and operational sustainability initiatives and (ii) improvement of peoples’ lives as a result of the Company’s projects that provide environmental, social and governance benefits. The Amended Revolving Credit Facility includes a $100 million sublimit for the issuance of standby letters of credit, a $20 million sublimit for swingline loans and a $300 million sublimit for multicurrency borrowings and letters of credit.

The entire Amended Term Loan Facility was drawn on February 18, 2022. The Amended Term Loan Facility is subject to quarterly amortization of principal at 5% annually commencing June 30, 2022. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a benchmark rate plus a margin that ranges from 1.000% to 1.875% per annum, or (b) a base rate for loans in U.S. dollars (the highest of the U.S. federal funds rate plus 0.50% per annum, the bank’s prime rate or the Secured Overnight Financing Rate ("SOFR") rate plus 1.00%, plus a margin that ranges from 0% to 0.875% per annum. In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The Amended Term Loan Facility is subject to the same interest rate provisions. The Amended Credit Agreement expires on February 18, 2027, or earlier at our discretion upon payment in full of loans and other obligations.

The Amended Credit Agreement contains certain affirmative and restrictive covenants, and customary events of default. The financial covenants provide for a maximum Consolidated Leverage Ratio of 3.25 to 1.00 (total funded debt/EBITDA, as defined in the Amended Credit Agreement) and a minimum Consolidated Interest Coverage Ratio of 3.00 to 1.00 (EBITDA/Consolidated Interest Charges, as defined in the Amended Credit Agreement). Our obligations under the Amended Credit Agreement are guaranteed by certain of our domestic subsidiaries and are secured by first priority liens on (i) the equity interests of certain of our subsidiaries, including those subsidiaries that are guarantors or borrowers under the Amended Credit Agreement, and (ii) the accounts receivable, general intangibles and intercompany loans and those of our subsidiaries that are guarantors or borrowers.

15. Derivative Financial Instruments

We ~~often~~ use certain interest rate derivative contracts to hedge interest rate exposures on our variable rate debt. ~~Also, we may~~We also enter ininto foreign currency derivative contracts with financial institutions to reduce the risk that cash flows and earnings could adversely be affected by foreign currency exchange rate fluctuations. Our hedging program is not designated for trading or speculative purposes.

We recognize derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value. We record changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as cash flow hedges in our consolidated balance sheets as accumulated other comprehensive income, and in our consolidated statements of income for those derivatives designated as fair value hedges. ~~The~~Our derivative contracts ~~to hedge interest exposure~~ are categorized within Level 2 of the fair value hierarchy.

In the fourth quarter of fiscal 2022, we entered into a forward contract to acquire GBP 714.0 million at a rate of 1.0852 for a total of USD 774.8 million that was integrated with our plan to acquire RPS. This contract matured on December 30, 2022. On December 28, 2022, we entered into an extension of the integrated forward contract to acquire GBP 714.0 million at a rate of 1.086 for a total of USD 775.4 million, extending the maturity date to January 23, 2023, the closing date of the RPS acquisition. Although an effective economic hedge of our foreign exchange risk related to this transaction, the forward contract did not qualify for hedge accounting. As a result, the forward contract was marked-to-market with changes in fair value recognized in earnings each period. The intrinsic value of the forward contract was immaterial at inception as the GBP/USD spot and forward exchange rates were essentially the same. The fair value of the forward contract at October 2, 2022 was $19.9 million, and an unrealized gain of the same amount was recognized in our fourth quarter of fiscal 2022 results. On January 23, 2023, the forward contract was settled at the fair value of $109.3 million. We recognized additional gains of

$68.0 million and $21.4 million in the first and second quarters of fiscal 2023, respectively. All gains related to this transaction were reported in “Other non-operating income" on our consolidated income statements for the respective periods.

In fiscal 2018, we ~~entere~~enterded into 5five interest rate swap agreements that we designated as cash flow hedges to fix the interest rate on the borrowings under our term loan facility. ~~As of~~At April ~~3, 2022,~~2, 2023, the notional principal of our outstanding interest swap agreements was ~~$206.3~~$193.8 million ($~~41.3~~38.8 million each.) The interest rate swaps have a fixed interest rate of 2.79%

and expire in July 2023 for all 5five agreements. At April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, the fair values of the effective portion of our interest rate swap agreements designated as cash flow hedges before tax effect were unrealized ~~losses~~gains of ~~$1.8~~$1.4 million and ~~$9.4~~$2.4 million, respectively, which were reported in "Other ~~current liabilities"~~non-current assets" on our consolidated balance sheets. Additionally, the related ~~gains~~loss of ~~$4.9~~$0.9 million and ~~$7.6~~$1.0 million for the three and six months ended April ~~3, 2022,~~2, 2023, compared to the related gains of ~~$1.9~~$4.9 million and ~~$3.4~~$7.6 million for the prior-year periods, were recognized and reported on our consolidated statements of comprehensive income. We expect to reclassify ~~$1.7~~a credit of $1.4 million from accumulated other comprehensive loss to interest expense ~~within~~during the ~~next twelve months.~~second half of fiscal 2023, up to the expiration date in July 2023. There were no other derivative instruments designated as hedging instruments for the ~~fir~~stfirst half ofof fiscal ~~2022.~~2023.

17. Commitments and Contingencies

We are subject to certain claims and lawsuits typically filed against the consulting and engineering profession, alleging primarily professional errors or omissions. We carry professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect, individually or in aggregate, on our financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters.

On July 15, 2019, following an initial January 14, 2019 filing, the Civil Division of the United States Attorney's Office filed an amended complaint in intervention in 3three qui tam actions filed against our subsidiary, Tetra Tech EC, Inc. ("TtEC"), in the U.S. District Court for the Northern District of California. The complaint alleges False Claims Act violations and breach of contract related to TtEC's contracts to perform environmental remediation services at the former Hunters Point Naval Shipyard in San Francisco, California. TtEC disputes the claims and will defend this matter vigorously. We are currently unable to determine the probability of the outcome of this matter or the range of reasonably possible loss, if any.

We are Leading with ~~Science®~~Science® throughout our operations, with domain experts across multiple disciplines supported by our advanced analytics, artificial intelligence, machine learning and digital technology solutions. Our ability to provide ~~innovation~~innovative and first-of-kind solutions is enhanced by partnerships with our forward-thinking clients. We are diverse, equitable and inclusive, embracing the breadth of experience across our talented workforce worldwide with a culture of innovation and entrepreneurship.

By combining ingenuity and practical experience, we have helped to advance sustainability by managing water, protecting the environment, providing clean energy, restoring ecosystems and engineering green solutions for our cities and communities.

We derive income from fees for professional, technical, program management, and construction management services. As primarily a professional services company, we are labor-intensive rather than capital-intensive. Our revenue is driven by our ability to attract and retain qualified and productive employees, identify business opportunities, secure new and renew existing client contracts, provide outstanding services to our clients and execute projects successfully. We provide services to a diverse base of U.S. federal government, U.S. state and local ~~government, U.S. federal~~ government, U.S. commercial and international clients.

The following table presents the percentage of our revenue by client sector:

We manage our operations under two reportable segments. Our Government Services Group ("GSG") reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our Commercial/International ~~Services~~ Group ("CIG") reportable segment primarily includes activities with U.S. commercial clients and international clients other than development agencies. Additionally, we continue to report the results of the wind-down of our non-core construction activities in the Remediation and Construction Management ("RCM") reportable segment. RCM's projects were complete at the end of fiscal 20~~18; however, there was an outstanding $11 million claim receivable in dispute resolution as of April 3, 2022.~~ ~~In May 2022, we received a cash settlement for this claim, which will result in an immaterial gain in the third quarter of fiscal 2022.~~ ~~There were no significant operating activities in RCM for the second quarters and first halves of fiscal 2022 and 2021.~~

Government Services Group (“GSG”). GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local) and development agencies worldwide. GSG supports U.S. government civilian and defense agencies with services in water, environment, sustainable infrastructure, information technology and disaster management. GSG also provides engineering design services for U.S. ~~municipal~~based federal and ~~commercial~~municipal clients, especially in water infrastructure, flood protection and solid ~~waste, and high-end sustainable infrastructure designs.~~waste. GSG also leads our support for development agencies worldwide, especially in the United States, United Kingdom and Australia.

Commercial/International ~~Services~~ Group (“CIG”). CIG primarily provides high-end consulting and engineering services to U.S. commercial clients, and international clients ~~that include both~~inclusive of the commercial and government sectors. CIG supports commercial clients across the Fortune 500, ~~clean~~renewable energy, industrial, high performance buildings and aerospace markets. CIG also provides sustainable infrastructure and related environmental, engineering and project management services to commercial and local government clients across Canada, in Asia Pacific (primarily Australia and New Zealand), the United Kingdom, as well as Brazil and Chile.

At the beginning of fiscal 2022, we aligned our operations to better serve our clients and markets, and created a new High Performance Buildings division in our CIG reportable segment. As a result, we transferred some related operations in our GSG reportable segment to our CIG reportable segment. Certain prior year amounts for reportable segments have been reclassified to conform to the current year presentation.

The following table presents the percentage of our revenue by reportable segment:


		Three Months Ended				Six Months Ended					Three Months Ended				Six Months Ended

Our services are performed under three principal types of contracts with our clients: fixed-price, time-and-materials and cost-plus. The following table presents the percentage of our revenue by contract type:


		Three Months Ended				Six Months Ended					Three Months Ended				Six Months Ended
		April 3, 2022		March 28, 2021		April 3, 2022		March 28, 2021			April 2, 2023		April 3, 2022		April 2, 2023		April 3, 2022

Under fixed-price contracts, clients agree to pay a specified price for our performance of the entire contract or a specified portion of the contract. Under time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and paid for other expenses. Under cost-plus contracts, some of which are subject to a contract ceiling amount, we are reimbursed for allowable costs plus fees, which may be fixed or performance-based. Profitability on these contracts is driven by billable headcount and our cost control. We recognize revenue from contracts using the cost-to-cost measure of progress method to estimate the progress towards completion to determine the amount of revenue and profit to recognize. Changes in those estimates could result in the recognition of cumulative catch-up adjustments to the contract’s inception-to-date revenue, costs and profit in the period in which such changes are made. On a quarterly basis, we review and assess our revenue and cost estimates for each significant contract. Changes in revenue and cost estimates could also result in a projected loss that would be recorded immediately in earnings.

Other contract costs include professional compensation and related benefits, together with certain direct and indirect overhead costs such as rents, utilities and travel. Professional compensation represents a large portion of these costs. Our "Selling, general and administrative expenses" ("SG&A") are comprised primarily of marketing and bid and proposal costs, and our corporate headquarters’ costs related to the executive offices, finance, accounting, administration and information technology. Our SG&A expenses also include a portion of stock-based compensation and depreciation of property and equipment related to our corporate headquarters, and the amortization of identifiable intangible assets. Most of these costs are unrelated to specific clients or projects, and can vary as expenses are incurred to support company-wide activities and initiatives.

We experience seasonal trends in our business. Our revenue and operating income are typically lower in the first half of our fiscal year, primarily due to the Thanksgiving (in the U.S.) and Canada), Christmas and New Year’s holidays. Many of our clients’ employees, as well as our own employees, take vacations during these holiday periods. Further, seasonal inclement weather conditions occasionally cause some of our offices to close temporarily or may hamper our project field work in the northern hemisphere's temperate and arctic regions. These occurrences result in fewer billable hours worked on projects and, correspondingly, less revenue recognized.

ACQUISITIONS AND DIVESTITURES

Acquisitions. We continuously evaluate the marketplace for acquisition opportunities to further our strategic growth plans. Due to our reputation, size, financial resources, geographic presence and range of services, we have numerous opportunities to acquire privately and publicly held companies or selected portions of such companies. We evaluate an acquisition opportunity based on its ability to strengthen our leadership in the markets we serve, the technologies and solutions they provide and the additional new geographies and clients they bring. Also, during our evaluation, we examine an acquisition's ability to drive organic growth, its accretive effect on long-term earnings and its ability to generate return on investment. Generally, we proceed with an acquisition if we believe that it will strategically expand our service offerings, improve our long-term financial performance and increase shareholder returns.

We view acquisitions as a key component in the execution of our growth strategy, and we intend to use cash, debt or equity, as we deem appropriate, to fund acquisitions. We may acquire other businesses that we believe are synergistic and will ultimately increase our revenue and net income, strengthen our ability to achieve our strategic goals, provide critical mass with existing clients and further expand our lines of service. We typically pay a purchase price that results in the recognition of goodwill, generally representing the intangible value of a successful business with an assembled workforce specialized in our areas of interest. Acquisitions are inherently risky, and no assurance can be given that our previous or future acquisitions will be successful or will not have a material adverse effect on our financial position, results of operations or cash flows. All acquisitions require the approval of our Board of Directors.

On January 23, 2023, we completed the acquisition of RPS Group plc ("RPS"), a publicly traded company on the London Stock Exchange in an all cash transaction totaling $784 million. We funded the RPS acquisition with debt, net of $109 million in proceeds from a foreign exchange forward contract that we entered into at the same time we made the formal offer to acquire RPS on September 23, 2022.

RPS employs approximately 5,000 associates in the United Kingdom, Europe, Asia Pacific and North America, delivering high-end solutions, especially in energy transformation, water and program management for government and commercial clients. In the second quarter of fiscal 2023, RPS contributed revenue of $169.5 million to our consolidated results. RPS contributed no material operating income to our results in the second quarter of fiscal 2023, as it was offset by $7.7 million of intangible amortization. Substantially all of RPS is included in our CIG segment.

For detailed information regarding acquisitions, see Note 4, “Acquisitions” of the “Notes to Consolidated Financial Statements”.

Divestitures. We regularly review and evaluate our existing operations to determine whether our business model should change through the divestiture of certain businesses. Accordingly, from time to time, we may divest or wind-down certain non-core businesses and reallocate our resources to businesses that better align with our long-term strategic direction.

OVERVIEW OF RESULTS AND BUSINESS TRENDS

General. As the coronavirus disease 2019 ("COVID-19") spread globally, we responded quickly to ensure the health and safety of our employees, clients and the communities we support. Our high-end consulting focus and the technologies we deployed have allowed our staff to support clients and projects remotely without interruption. We remain focused on providing clients with the highest level of service and our 450 global offices are operational, supporting our programs and projects. By ~~Leading with Science®, we are responding to the current global challenges including COVID-19, with the commitment of our~~ ~~21,000 associates~~ supported by technological innovation. The actions we have taken to navigate through this worldwide pandemic, the strength of our balance sheet, and our technical leadership position us well to address the global challenges of providing clean water, environmental restoration, and the impacts of climate change.

In the first half of fiscal ~~2022,~~2023, revenue increased ~~12.6%~~20.0% compared to the prior-year period. This year-over-year growth reflects increased activity ~~with U.S. state~~in all of our client sectors and ~~local government clients and commercial clients. Our international activities with both commercial and government clients have also contributed to~~the aforementioned RPS acquisition. Excluding RPS, our revenue ~~growth. Our revenue also includes contributions from acquisitions that did not contribute to our revenue~~increased 10.1% in the first half of fiscal ~~2021.~~2023 compared to the year-ago period.

U.S. Federal Government. InOur U.S. federal government revenue increased 26.6% in the ~~second~~first half of fiscal ~~2022, we~~2023 compared to the same quarter last year. This increase was primarily due to more international development and broad-based increases in our water and environmental programs. During periods of economic volatility, our U.S. federal government business has historically been the most stable and predictable. We expect our U.S. federal government revenue to continue to grow ~~year-over-year at a rate similar to~~in the ~~first half~~remainder of fiscal ~~2022 after normalizing for~~2023. Approximately $1 trillion in new U.S. federal funding passed in 2021 through the ~~extra week~~Infrastructure Investment and Jobs Act, the Inflation Reduction Act and the CHIPS and Science Act. Each of ~~operations~~these programs include substantial planned investments in our key end markets including water, environment and sustainable infrastructure over the ~~fourth quarter of fiscal 2021. We report results of operations based on 52/53 week periods ending on the Sunday nearest September 30. As a result, our fiscal 2021 had 53 weeks compared~~next five to ~~52 weeks this year with the extra week occurring in the fourth quarter of fiscal 2021.~~ten years.

U.S. State and Local Government. Our U.S. state and local government revenue ~~increased 23.7%~~decreased 4.5% in the first half of fiscal ~~2022~~2023 compared to the same quarter last year due to lower disaster response activity. Excluding disaster response, our state and local government revenue increased 20.2% in the first half of fiscal 2023 compared to the same period last year. The increase reflects continued broad-based growth in our U.S. state ~~and~~and local government ~~project-related~~ infrastructure business, particularly with increased revenue from municipal water infrastructure work, ~~in the metropolitan areas of California, Texas and Florida. Our disaster response activities also increased compared to the first half of fiscal 2021.~~including digital water projects. Most of our work for the U.S. state and local governments relates to critical water and environmental programs, which we expect to continue to grow ~~for~~in the remainder of fiscal ~~2022.~~

~~U.S. Federal Government.~~ Our U.S. federal government revenue decreased 2.5% in the first half of fiscal 2022 compared to the prior-year period. The decrease was due to reduced international development activity, especially in Afghanistan. This decline was partially offset by increased year-over-year revenue for both Department of Defense and civilian agencies. During periods of economic volatility, including during the COVID-19 pandemic, our U.S. federal government business has historically been the most stable and predictable. Our revenue also includes contributions from acquisitions that did not contribute to our revenue in the first half of fiscal 2021. We expect our U.S. federal government revenue to grow for the remainder of fiscal 2022 primarily due to increased advanced analytics activity and the current administration's focus on long-term infrastructure and climate change.2023.

U.S. Commercial. Our U.S. commercial revenue increased ~~15.6%~~16.9% in the first half of fiscal ~~2022~~2023 compared to the same ~~period~~quarter last year. Excluding the contribution from RPS, our U.S. commercial revenue increased 11.0% in the first half of fiscal 2023 compared to the first half of fiscal 2022. This increase was primarily due to more activity on renewable energy and environmental programs, including meeting net zero carbon goals and designing high performance buildings. We expect ~~these trends and the related~~ growth in our U.S. commercial work to continue ~~for~~in the remainder of fiscal ~~2022.~~2023.

International. Our international revenue increased ~~22.7%~~30.1% in the first half of fiscal ~~2022~~2023 compared to the ~~prior-year period. The~~same quarter last year. Excluding the contribution from RPS, our international revenue increased approximately 3% despite a stronger U.S. dollar and the adverse impact on our foreign currency translation year-over-year. On a constant currency basis, our international revenue, excluding RPS, increased approximately 12% in the first half of fiscal 2023 compared to the first six month of last year. This revenue growth ~~primarily~~ reflects government stimulus spending on infrastructure and commercial ~~activity~~activities related to an increased focus on ~~sustainability~~. ~~Our revenue also includes contributions from acquisitions that did not contribute to our revenue in the first half of fiscal 2021.~~sustainability.

(1) We believe that the presentation of “Revenue, net of subcontractor costs”, which is a non-U.S. GAAP financial measure, enhances investors’ ability to analyze our business trends and performance because it substantially measures the work performed by our employees. While providing services, we routinely subcontract various services and, under certain U.S. Agency for International Development programs, issue grants. Generally, these subcontractor costs and grants are passed through to our clients and, in accordance with U.S. GAAP and industry practice, are included in our revenue when it is our contractual responsibility to procure or manage these activities. The grants are included as part of our subcontractor costs. Because subcontractor services can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of our business trends. Accordingly, we segregate subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive of costs associated with external service providers.

Operating income ~~increased $13.7~~decreased $13.5 million, or ~~22.6%~~18.1%, in the second quarter of fiscal ~~2022~~2023 compared to the second quarter of last year. In the first half of fiscal ~~2022,~~2023, operating income ~~increased $34.7~~decreased $8.7 million, or ~~27.3%~~5.4%, compared to the first half of fiscal ~~2021.~~2022. The second quarter and first half of fiscal 2023 results include $19.9 million and $23.7 million of acquisition and integration expenses (primarily legal and other professional fees), respectively, for the RPS acquisition. The second quarter and first half of fiscal 2023 results also include losses of $7.5 million and $8.5 million, respectively, related to changes in the estimated fair value of contingent earn-out liabilities. The first half of fiscal 2022 results ~~include~~(all in the first quarter) included the benefit of ERC's totaling $4.5 million, which represents reimbursement from the U.S. federal government under the Coronavirus Aid, Relief and Economic Security Act for the costs that we incurred during the second quarter of fiscal 2020 to address the COVID-19 pandemic. These amounts were recognized in ~~the first quarter of~~ fiscal 2022 when the funds were received due to the uncertainty related to the computation of qualifying amounts and delayed processing times for our application. These amounts were primarily reflected as a reduction to "Other ~~Costs~~costs of ~~Revenue"~~revenue" in our ~~Consolidated Statement~~consolidated statement of ~~Income~~income and an increase to ~~"Cash Provided~~"Net cash provided by ~~Operations"~~operating activities" in our ~~Consolidated Statement~~consolidated statement of ~~Cash Flows~~cash flows for ~~the first half of~~ fiscal 2022, consistent with the presentation of the related costs recognized in the second quarter of fiscal 2020. ~~The ERC's increased operating income~~

We expect to incur additional integration expenses related to the RPS acquisition, primarily for information technology systems integration and real estate consolidation, in the second half of fiscal 2023. These costs may be material to our ~~GSG~~consolidated financial results.

Excluding the acquisition expenses, earn-out losses and ~~CIG segments by $3.1 million and $1.4 million, respectively. Excluding~~ the ERC's our adjusted operating income increased ~~$30.2~~$14.0 million, or ~~23.8%~~18.8% in the second quarter and $28.0 million, or 17.8%, in the first half of fiscal ~~2022~~2023 compared to ~~year-ago period.~~the same periods last year. These increases reflect improved results in both GSG and CIG segments, which are described below under "Government Services Group" and "Commercial/International ~~Services~~ Group", respectively.

Our net interest expense was $13.3 million in the second quarter and $18.7 million in the first half of fiscal 2023 compared to $3.1 million and $6.0 million, respectively, in the same periods of last year. Net interest expense in the first quarter of fiscal 2023 included $2.7 million of additional expense for the write-off of previously deferred debt origination fees due to the cancellation of the bridge loan facility that we entered to support our offer to acquire RPS, which was replaced with an amendment to our existing debt facility. Net interest expense in the second quarter of fiscal 2023 included $1.1 million of additional expense for the write-off of previously deferred debt origination fees due to the repayment and cancellation of RPS' debt facilities. Excluding these write-offs, our interest expense increased ~~$0.3~~$9.1 million in the second quarter and $8.9 million in the first half of fiscal 2023 compared to the same periods last year primarily due to the additional borrowings to fund the RPS acquisition.

Other non-operating income of $21.4 million and ~~$0.2~~$89.4 million in the second quarter and first half of fiscal ~~2022,~~2023, respectively, ~~compared to~~reflect gains on a foreign exchange forward contract integrated with the ~~prior-year periods. The increased interest expense~~RPS acquisition. Although an effective economic hedge of our foreign exchange risk related to ~~our contingent earn-out liabilities~~this transaction, the forward contract did not qualify for hedge accounting. As a result, the forward contract was ~~substantially offset by~~marked-to-market with changes in fair value recognized in earnings each period. The forward contract was settled on January 23, 2023, together with the ~~benefit~~closing of ~~lower average year-over-year borrowings.~~the RPS acquisition, with a cumulative gain of approximately $109 million.

The effective tax rates for the first halves of fiscal 2023 and 2022 were 28.7% and ~~2021 were~~ 21.9% ~~and 19.2%~~, respectively. Income tax expense was reduced by ~~$4.8~~$1.8 million and ~~$8.0~~$4.8 million of excess tax benefits on share-based payments in the first halves of fiscal 2023 and 2022, respectively. In addition, income tax expense in the first half of fiscal 2023 (all in the second quarter) included non-operating income tax expenses of $6.7 million to recognize the tax liability for foreign earnings, primarily in the U.K. and ~~2021, respectively.~~Australia, that are no longer indefinitely reinvested and to increase the liability for an uncertain tax position. Excluding the impact of ~~these~~the excess tax benefits on share-based payments and the non-operating tax expenses in the second quarter of fiscal 2023, our effective tax rates ~~for~~in the first halves of fiscal 2023 and 2022 were 26.5% and ~~2021 were~~ 25.0% ~~and 25.8%~~, respectively.

Our EPS was ~~$0.98~~$0.80 and ~~$2.23~~$2.98 in the second quarter and first half of fiscal ~~2022,~~2023 compared to ~~$0.83~~$0.98 and ~~$1.79~~$2.23 in the prior-year periods. Excluding the aforementioned non-operating and non-recurring items, our adjusted EPS was $1.06 in the second quarter of fiscal 2023 compared to $0.98 in the year-ago quarter, an increase of 8.2%. On the same basis, as our ~~adjusted operating income,~~first half adjusted EPS was $2.40 in fiscal 2023 compared to $2.17 last year, an increase of 10.6%. We estimate that RPS was $0.03 dilutive to our adjusted EPS in the second quarter and first half of fiscal 2023 before intangible amortization, which reduced our EPS by an additional $0.11. Excluding RPS, our adjusted EPS was $1.20 in the second quarter and $2.54 in the first half of fiscal 2023 representing increases of 22.4% and 17.1%, respectively, compared to the same periods in fiscal 2022.

Operating income increased ~~$8.9~~$1.9 million and ~~$17.4~~$11.0 million in the second quarter and first half of fiscal ~~2022,~~2023, respectively, compared to the prior-year periods. Operating income in the second quarter of fiscal 2023 from the aforementioned work in Ukraine was more than offset by lower operating income on disaster response projects. In addition, last year's first quarter and first half ~~of fiscal 2022~~results included $3.1 million of the aforementioned ERC's. ~~Excluding this benefit, operating income increased 17.0% in the first half of fiscal 2022 compared to the same period last year.~~ Our operating margin, based on revenue, net of subcontractor costs, ~~improved~~declined to ~~15.3% for~~14.3% in the first half of fiscal ~~2022~~2023 compared to ~~13.7% for~~15.3% in the first half of fiscal ~~2021~~2022. Excluding last year's ERC's, our operating margin was 14.9% in the first half of fiscal 2022. The lower operating margin in fiscal 2023 was due to a higher proportion of international development revenue in the first half of fiscal 2023 compared to the same period last year. Our international development revenue, including the activity in Ukraine this year, tends to have a lower operating margin than the rest of our revenue in the GSG segment.

Revenue increased $193.4 million, or 46.4%, and revenue, net of subcontractor costs, increased $171.9 million, or 47.5%, in the second quarter of fiscal 2023 compared to last year's second quarter. For the first half of fiscal 2023, revenue increased $216.7 million, or 26.0%, and revenue, net of subcontractor costs, increases $203.1 million, or 28.4%, compared to

the first half of fiscal 2022. The RPS acquisition contributed approximately $170 million to revenue growth in the second quarter and first half of fiscal 2023. The remaining revenue growth in both the second quarter and first half of fiscal 2023 primarily reflects increased activity on high performance buildings and renewable energy.

Operating income increased $12.0 million and $16.8 million, in the second quarter and first half of fiscal 2023, respectively, compared to the same periods last year. The RPS acquisition contributed approximately $7 million to operating income in the second quarter and first half of fiscal 2023. The fiscal 2022 operating income included $1.4 million of the aforementioned ERC's. Our operating margin, based on revenue, net of subcontractor costs, was 11.2% in the first half of fiscal 2023 compared to 12.0% in the prior-year period. Excluding RPS and the ERC's, our operating margin was ~~14.8%~~12.3% in the first half of fiscal 2023 compared to 11.8%% in the first half of fiscal 2022. The improved operating margin was primarily due to our increased focus on high-end consulting services, project execution and ~~improved labor utilization.~~

Revenue increased $81.5 million, or 24.3%, and revenue, net of subcontractor costs, increased $72.9 million, or 25.2%, in the second quarter of fiscal 2022 compared to last year's second quarter. For the first half of fiscal 2022, revenue increased $141.3 million, or 20.4%, and revenue, net of subcontractor costs, increased $124.6 million, or 21.1%, compared to the first half of fiscal 2021. The revenue growth in the first half of fiscal 2022 primarily reflects more activity on commercial environmental programs, including meeting net zero carbon goals and high performance buildings. These increases were also

due to international government stimulus spending on infrastructure. Additionally, revenue in the first half of fiscal 2022, includes contributions from acquisitions, which did not have comparable revenue in the first half of last year.

Operating income increased $9.5 million and $20.3 million, in the second quarter and first half of fiscal 2022, respectively, compared to the same periods last year. Operating income in the first half of fiscal 2022 included $1.4 million of the aforementioned ERC's. Excluding this benefit, operating income increased 28.9% in the first half of fiscal 2022 compared to fiscal 2021 period. Our operating margin, based on revenue, net of subcontractor costs, improved to 12.0% for the first half of fiscal 2022 compared to 11.1% for the prior-year period. Excluding the ERC's, our operating margin was 11.8% for the first half of fiscal 2022. The improved operating margin was primarily due to our increased focus on high-end consulting services and improved labor utilization.

Backlog

Backlog generally represents the dollar amount of revenues we expect to realize in the future when we perform the work. The difference between remaining unsatisfied performance obligations ("RUPO") and backlog relates to contract terms. Specifically, our backlog does not consider the impact of termination for convenience clauses within the contracts. The contract term and thus remaining performance obligation on certain of our operations and maintenance contracts, are limited to the notice period required for contract termination (usually 30, 60, or 90 ~~days)~~days). At April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~ 2, 2022, the differences between our backlog and RUPO o~~f $3.6~~of $4.2 billion for each period were immaterial.

Financial Condition, Liquidity and Capital Resources

Capital Requirements. ~~As of~~At April ~~3, 2022,~~2, 2023, we had ~~$194.4~~$231.4 million of cash and cash equivalents and access to an additional ~~$799.3~~$459.3 million of borrowings available under our amended credit ~~facility.~~facility described below. During the first half of fiscal ~~2022,~~2023, we generated ~~$177.5~~$113.1 million of cash from operations. ~~To date, we have not experienced any significant deterioration in our financial condition or liquidity due to the COVID-19 pandemic and our credit facilities remain available.~~

Our primary sources of liquidity are cash flows from operations and borrowings under our credit facilities. Our primary uses of cash are to fund working capital, ~~stock repurchases,~~ cash dividends, capital expenditures and repayment of debt, as well as to fund acquisitions and earn-out obligations from prior acquisitions. We believe that our existing cash and cash equivalents, operating cash flows and borrowing capacity under our credit agreement as amended for the RPS acquisition in the second quarter of fiscal 2023, as described below, will be sufficient to meet our capital requirements for at least the next 12 months.

We use a variety of tax planning and financing strategies to manage our worldwide cash and deploy funds to locations where they are needed. We ~~currently have no need or plans~~plan to repatriate undistributed foreign earnings ~~other than from Canada,~~as they become available to supplement our liquidity in the ~~foreseeable future; however, this could change due~~United States including to ~~varied economic circumstances.~~pay down the borrowings used to fund the RPS acquisition.

On October 5, 2021, ~~the~~our Board of Directors authorized a new stock repurchase program under which we could repurchase up to $400 million of our common ~~stock in addition to the $147.8 million remaining under the previous stock repurchase program at October 3, 2021.~~stock. In the first half of fiscal ~~2022,~~2023, we ~~repurchased and settled 618,236~~did not repurchase any shares ~~with an average price~~ of ~~$161.75 per share for a total cost of $100.0 million in the open market.~~our common stock. At April ~~3, 2022,~~2, 2023, we had a remaining balance of ~~$447.8~~$347.8 million under our stock repurchase program.

On November 15, 2021, the Board of Directors declared a quarterly cash dividend of $0.20 per share payable on December 20, 2021 to stockholders of record as of the close of business on December 2, 2021. On January 31,7, 2022, ~~the Board of Directors declared a quarterly cash dividend of $0.20 per share payable on February 25, 2022 to stockholders of record as of the close of business on February 11, 2022.~~

~~Subsequent Event.~~ ~~On May 2, 2022 the~~our Board of Directors declared a quarterly cash dividend of $0.23 per share payable on ~~May 27,~~December 9, 2022 to stockholders of record as of the close of business on November 21, 2022. On January 30, 2023, our Board of Directors declared a quarterly cash dividend of $0.23 per share payable on February 24, 2023 to stockholders of record as of the close of business on February 13, 2023.

Subsequent Event. On May ~~13, 2022.~~8, 2023, our Board of Directors declared a quarterly cash dividend of $0.26 per share payable on June 6, 2023 to stockholders of record as of the close of business on May 24, 2023.

Cash and Cash ~~Equivalents.~~Equivalents.. ~~As of~~At April ~~3, 2022,~~2, 2023, our cash and cash equivalents w~~ere $194.4~~were $231.4 million, an increase of ~~$27.8~~$46.3 million compared to the fiscal ~~2021~~2022 year-end. The increase was primarily due to ~~net~~ cash provided by operating activities ~~partially offset by stock repurchases, dividends, as well as payments for taxes on vested restricted stock.~~and cash obtained in the RPS acquisition.

Operating Activities. For the first half of fiscal ~~2022,~~ 2023, net cash provided by operating activities was ~~$177.5~~$113.1 million, ~~an increase~~a decrease of ~~$20.1~~$64.4 million compared toto the prior-year period. The ~~increase~~decrease was primarily ~~reflects an increase in earnings adjusted for non-cash items and improved working capital from faster collections of our receivables in the first half of fiscal 2022 compared~~due to the ~~fiscal 2021 period.~~timing of payments to our vendors and employees.

Investing Activities. For the first half of fiscal ~~2022,~~ 2023, net cash used in investing activities was ~~$35.6~~$755.2 million, an increase of ~~$28.3~~$719.7 million compared to the ~~prior-year~~ year-ago period. The increase was primarily due to ~~payments related to~~ the ~~acquisitions completed~~RPS acquisition in the ~~first half~~second quarter of fiscal ~~2022.~~2023.

Financing Activities.

The ~~increase was due to higher stock repurchases, taxes paid on vested restricted stock and stock options exercised. The increased uses of cash were partially offset by higher net borrowings~~financing activities in the first half of fiscal ~~2022, which was~~2023 primarily ~~used~~consisted of additional borrowings to fund ~~acquisitions.~~the RPS acquisition.

Debt Financing. On October 26, 2022, we entered into a Third Amended and Restated Credit Agreement that provides for an additional $500 million senior secured term loan facility (the "New Term Loan Facility") increasing our total borrowing capacity to $1.55 billion. On January 23, 2023, we drew the entire amount of the New Term Loan Facility to partially finance the RPS acquisition. The New Term Loan Facility is not subject to any amortization payments of principal and matures on the third anniversary of the RPS acquisition closing date.

On February 18, 2022, we entered into Amendment No. 2 to our Second Amended and Restated Credit Agreement (“Amended Credit Agreement”) with a total borrowing capacity of $1.05 billion that will mature in February 2027. The Amended Credit Agreement is a $750 million senior secured, five-year facility that provides for a $250 million term loan facility (the “Amended Term Loan Facility”) and a $500 million revolving credit facility (the “Amended Revolving Credit Facility”). In addition, the Amended Credit Agreement includes a $300 million accordion feature that allows us to increase the Amended Credit Agreement to $1.05 billion subject to lender approval. The Amended Credit Agreement provides for, among other things, (i) refinance indebtedness under our Credit Agreement dated as of July 30, 2018; (ii) finance open market repurchases of common stock, acquisitions and cash dividends and distributions; and (iii) utilize the proceeds for working capital, capital expenditures and other general corporate purposes. The Amended Credit Agreement provides for a reduction in the interest grid for meeting certain sustainability targets related to the (i) reduction of greenhouse gas emissions through the Company’s projects and operational sustainability initiatives and (ii) improvement of peoples’ lives as a result ofthe Company’s projects that provide environmental, social and governance benefits. The Amended Revolving Credit Facility includes a $100 million sublimit for the issuance of standby letters of credit, a $20 million sublimit for swingline loans and a $300 million sublimit for multicurrency borrowings and letters of credit.

~~As of~~At April ~~3, 2022,~~2, 2023, we had ~~$250.0 million.~~$1.08 billion in outstanding borrowings under the Amended Credit Agreement, which was comprised of ~~$250.0~~$237.5 million under the Amended Term Loan Facility, $500 million under the New Term Loan Facility, and ~~no outstanding borrowings~~$340 million under the Amended Revolving Credit Facility. The year-to-date weighted-average interest rate of the outstanding borrowings during April ~~3, 2022~~2, 2023 is ~~1.27%~~5.46%. In addition, we had $0.7 million in standby letters of credit under the Amended Credit Agreement. Our year-to-date weighted-average interest rate on borrowings outstanding under the Amended Credit Agreement, including the effects of interest rate swap agreements described in Note 15, “Derivative Financial Instruments” of the “Notes to Consolidated Financial Statements”, was ~~3.50%~~5.03%. At April ~~3, 2022,~~2, 2023, we had ~~$499.3~~$159.3 million of available credit under the Amended Revolving Credit Facility, all of which could be borrowed without a violation of our debt covenants.

The Amended Credit Agreement contains certain affirmative and restrictive covenants, and customary events of default. The financial covenants provide for a maximum Consolidated Leverage Ratio of 3.25 to 1.00 (total funded debt/EBITDA, as defined in the Amended Credit Agreement) and a minimum Consolidated Interest Coverage Ratio of 3.00 to 1.00 (EBITDA/Consolidated Interest Charges, as defined in the Amended Credit Agreement). Our obligations under the Amended Credit Agreement are guaranteed by certain of our domestic subsidiaries and are secured by first priority liens on (i) the equity interests of certain of our subsidiaries, including those subsidiaries that are guarantors or borrowers under the Amended Credit Agreement, and (ii) the accounts receivable, general intangibles and intercompany loans, and those of our subsidiaries that are guarantors or borrowers. At April ~~3, 2022,~~2, 2023, we were in compliance with these covenants with a consolidated leverage ratio of ~~0.82x~~2.44x and a consolidated interest coverage ratio of ~~28.09x.~~14.24x.

In addition to the Amended Credit Agreement, we maintain other credit facilities, which may be used for short-term cash advances and bank guarantees. At April ~~3, 2022,~~2, 2023, there were no ~~outstanding~~ borrowings under these facilities, and the aggregate amount of standby letters of credit outstanding was ~~$51.7~~$56.5 million. ~~As of~~At April ~~3, 2022,~~2, 2023, we had no bank overdrafts related to our disbursement bank accounts.

Inflation. We believe our operations have not been, and, in the foreseeable future, are not expected to be, materially adversely affected by inflation or changing prices due to the average duration of our projects and our ability to negotiate prices as contracts end and new contracts begin.

Dividends. Our Board of Directors has authorized the following dividends in fiscal ~~2022:~~2023:

Income Taxes

We evaluate the realizability of our deferred tax assets by assessing the valuation allowance and adjust the allowance, if necessary. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets. The ability or failure to achieve the forecasted taxable income in the applicable taxing jurisdictions could affect the ultimate realization of deferred tax assets. Based on projected future operating results in certain jurisdictions, it is unlikely that the current valuation allowance positions of those jurisdictions could be adjusted in the next 12 months.

~~As of~~ At April ~~3, 2022~~2, 2023 and October ~~3, 2021,~~2, 2022, the liability for income taxes associated with uncertain tax positions was $~~13.9~~42.4 million ~~and~~ an~~$14.1~~d $10.6 million, respectively.

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions may significantly decrease within the next 12 months. These liabilities represent our current estimates of the additional tax liabilities that we may be assessed when the related audits are concluded. If these audits are resolved in a manner more unfavorable than our current expectations, our additional tax liabilities could be materially higher than the amounts currently recorded resulting in additional tax expense.

Off-Balance Sheet Arrangements

In the ordinary course of business, we may use off-balance sheet arrangements if we believe that such arrangements would be an efficient way to lower our cost of capital or help us manage the overall risks of our business operations. We do not believe that such arrangements have had a material adverse effect on our financial position or our results of operations.

The following is a summary of our off-balance sheet arrangements:

•Letters of credit and bank guarantees are used primarily to support project performance and insurance programs. We are required to reimburse the issuers of letters of credit and bank guarantees for any payments they make under the outstanding letters of credit or bank guarantees. Our Amended Credit Agreement and additional letter of credit facilities cover the issuance of our standby letters of credit and bank guarantees and are critical for our normal operations. If we default on the Amended Credit Agreement or additional credit facilities, our inability to issue or renew standby letters of credit and bank guarantees would impair our ability to maintain normal operations. At April ~~3, 2022,~~2, 2023, we had $0.7 million in standby letters of credit outstanding under our Amended Credit Agreement and ~~$51.7~~$56.5 million inin standby letters of credit outstanding under our additional letter of credit facilities.

•From time to time, we provide guarantees and indemnifications related to our services. If our services under a guaranteed or indemnified project are later determined to have resulted in a material defect or other material deficiency, then we may be responsible for monetary damages or other legal remedies. When sufficient information about claims on guaranteed or indemnified projects is available and monetary damages or other costs or losses are determined to be probable, we recognize such guaranteed losses.

•In the ordinary course of business, we enter into various agreements as part of certain unconsolidated subsidiaries, joint ventures and other jointly executed contracts where we are jointly and severally liable. We enter into these agreements primarily to support the project execution commitments of these entities. The potential payment amount of an outstanding performance guarantee is typically the remaining cost of work to be

performed by or on behalf of third parties under engineering and construction contracts. However, we are not able to estimate other amounts that may be required to be paid in excess of estimated costs to complete contracts and, accordingly, the total potential payment amount under our outstanding performance guarantees cannot be

estimated. For cost-plus contracts, amounts that may become payable pursuant to guarantee provisions are normally recoverable from the client for work performed under the contract. For lump sum or fixed-price contracts, this amount is the cost to complete the contracted work less amounts remaining to be billed to the client under the contract. Remaining billable amounts could be greater or less than the cost to complete. In those cases where costs exceed the remaining amounts payable under the contract, we may have recourse to third parties, such as owners, co-venturers, subcontractors or vendors, for claims.

•In the ordinary course of business, our clients may request that we obtain surety bonds in connection with contract performance obligations that are not required to be recorded in our consolidated balance sheets. We are obligated to reimburse the issuer of our surety bonds for any payments made thereunder. Each of our commitments under performance bonds generally ends concurrently with the expiration of our related contractual obligation.

Critical Accounting Policies

Our critical accounting policies are disclosed in our Annual Report on Form 10-K for the fiscal year ended October ~~3, 2021.~~2, 2022. To date, there have been no material changes in our critical accounting policies as reported in our ~~2021~~2022 Annual Report on Form 10-K.

New Accounting Pronouncements

For information regarding recent accounting pronouncements, see “Notes to Consolidated Financial Statements” included in Part I, Item 1 of this Quarterly Report.

Financial Market Risks

We do not enter into derivative financial instruments for trading or speculation purposes. In the normal course of business, we have exposure to both interest rate risk and foreign currency transaction and translation risk, primarily related to the Canadian and Australian dollar, and British Pound.

We are exposed to interest rate risk under our Amended Credit Agreement. We can borrow, at our option, under both the Amended Term Loan Facility and Amended Revolving Credit Facility. We may borrow on the Amended Revolving Credit Facility, at our option, at either (a) a ~~benchmark~~Eurocurrency rate plus a margin that ranges from 1.000% to 1.875% per annum, or (b) a base rate for loans in U.S. dollars (the highest of the U.S. federal funds rate plus 0.50% per annum, the bank’s prime rate or the SOFR rate plus 1.00%) plus a margin that ranges from 0% to 0.875% per annum. In each case, the applicable margin is based on our Consolidated Leverage Ratio, calculated quarterly. The Amended Term Loan Facility is subject to the same interest rate provisions. Borrowings at the base rate have no designated term and may be repaid without penalty any time prior to the Facility’s maturity date. Borrowings at a SOFR rate have a term no ~~less~~less than 30 days and no greater than 180 days and may be prepaid without penalty. Typically, at the end of such term, such borrowings may be rolled over at our discretion into either a borrowing at the base rate or a borrowing at a SOFR rate with similar terms, not to exceed the maturity date of the Facility. The Facility matures on February 18, 2027. At April ~~3, 2022,~~2, 2023, we had ~~$250.0 million~~$1.08 billion in outstanding borrowings under the Amended Credit Agreement, which was comprised of ~~$250.0~~$237.5 million under the Amended Term Loan Facility, $500 million under the New Term Loan Facility, and ~~no outstanding borrowings~~$340 million under the Amended Revolving Credit Facility. The year-to-date weighted-average interest rate of the outstanding borrowings during fiscal ~~2022~~2023 was ~~1.27%~~5.46%.

In August 2018, we entered into five interest rate swap agreements with five banks to fix the variable interest rate on $250 million of our Amended Term Loan Facility. The ~~objective~~objective of these interest rate swaps was to eliminate the variability of our cash flows on the amount of interest expense we pay under our Credit Agreement. ~~As of~~At April ~~3, 2022,~~2, 2023, the notional principal of our outstanding interest swap agreements was ~~$206.3~~$193.8 million ($~~41.3~~38.8 million each.) Our year-to-date average effective interest rate on borrowings outstanding under the Credit Agreement, including the effects of interest rate swap agreements, at April ~~3, 2022,~~2, 2023, was ~~3.50%~~5.03%. For more information, see Note 15, “Derivative Financial ~~Instruments”~~Instruments” of the “Notes to Consolidated Financial Statements”.

~~Most~~The majority of our transactions are in U.S. dollars; however, some of our subsidiaries conduct business in foreign currencies, primarily the Canadian and Australian dollar, and British Pound. Therefore, we are subject to currency exposure and volatility because of currency fluctuations. We attempt to minimize our exposure to these fluctuations by matching revenue and expenses in the same currency for our contracts. ~~For the first half of fiscal 2021, we reported $1.3 million of~~We report our foreign currency gains and losses in

~~“Selling,~~ “Selling, general and administrative expenses” on our consolidated statements of income. The impact of the foreign currency ~~impact~~gains and losses was immaterial for the first ~~half~~halves of fiscal ~~2022 was immaterial.~~2023 and 2022.

We have foreign currency exchange rate exposure in our results of operations and equity primarily because of the currency translation related to our foreign subsidiaries where the local currency is the functional currency. To the extent the U.S. dollar strengthens against foreign currencies, the translation of these foreign currency denominated transactions will result in reduced revenue, operating expenses, assets and liabilities. Similarly, our revenue, operating expenses, assets and liabilities will increase if the U.S. dollar weakens against foreign currencies. For the first halves of fiscal ~~2022~~2023 and ~~2021,~~2022, 33.4% and 30.8% ~~and 28.3%~~ of our consolidated revenue, respectively, was generated by our international business. For the first half of fiscal ~~2022,~~2023, the effect of foreign exchange rate translation on the consolidated balance sheets was an increase in our equity by ~~$2.1~~$25.0 million compared to an increase in equity of ~~$43.4~~$2.1 million in the first half of fiscal ~~2021.~~2022. These amounts were recognized as adjustments to equity through other comprehensive income.
