NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2022

($ and share values in thousands, except per share data)

(Unaudited)


1.			NATURE OF OPERATIONS

Business Summary

Sterling Construction Company, Inc. (“Sterling,” “the Company,” “we,” “our” or “us”), a Delaware corporation, operates through a variety of subsidiaries within three segments specializing in E-Infrastructure, Transportation and Building Solutions in the United States (the “U.S.”), primarily across the Southern, Northeastern, Mid-Atlantic and the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. E-Infrastructure Solutions projects develop advanced, large-scale site development systems and services for data centers, e-commerce distribution centers, warehousing, transportation, energy and more. Transportation Solutions includes infrastructure and rehabilitation projects for highways, roads, bridges, airports, ports, light rail, water, wastewater and storm drainage systems. Building Solutions projects include residential and commercial concrete foundations for single-family and multi-family homes, parking structures, elevated slabs and other concrete work. From strategy to operations, we are committed to sustainability by operating responsibly to safeguard and improve society’s quality of life. Caring for our people and our communities, our customers and our investors – that is The Sterling Way.


2.			BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Presentation Basis—The accompanying Condensed Consolidated Financial Statements are presented in accordance with accounting policies generally accepted in the United States (“GAAP”) and reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See Note 5 - Consolidated 50% Owned Subsidiaries and Note 6 - Construction Joint Ventures for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation. Values presented within tables (excluding per share data) are in thousands. Reclassifications have been made to historical financial data in the Condensed Consolidated Financial Statements to conform to the current year presentation.

Estimates and Judgments—The preparation of the accompanying Condensed Consolidated Financial Statements in conformance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-lived assets, goodwill and purchase accounting estimates. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.

Significant Accounting Policies

Consistent with Regulation S-X Rule 10-1(a), the Company has omitted significant accounting policies in this quarterly report that would duplicate the disclosures contained in the Company’s annual report on Form 10-K for the year ended December 31, 2021 under “Part II, Item 8. - Notes to Consolidated Financial Statements.” This quarterly report should be read in conjunction with the Company’s most recent annual report on Form 10-K.

Accounts Receivable—Receivables are generally based on amounts billed to the customer in accordance with contractual provisions. Receivables are written off based on the individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. The Company performs a review of outstanding receivables, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At March 31, 2022 and December 31, 2021, our allowance for our estimate of expected credit losses was zero.

Contracts in Progress—For performance obligations satisfied over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Typically, Sterling bills for advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. However, the Company occasionally bills subsequent to revenue recognition, resulting in contract assets.

Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. At March 31, 2022 and December 31, 2021, contract assets included $33,016 and $47,308 of retainage, respectively, and contract liabilities included $66,361 and $46,882 of retainage, respectively. Retainage on active contracts is classified as current regardless of the term of the contract and is generally collected within one year of the completion of a contract. We anticipate collecting approximately 64% of our March 31, 2022 retainage during the next twelve months. These assets and liabilities are reported on the Condensed Consolidated Balance Sheet within “Contract assets” and “Contract liabilities” on a contract-by-contract basis at the end of each reporting period.

Revenue recognized for the three months ended March 31, 2022 that was included in the contract liability balance on December 31, 2021 was $227,079. Revenue recognized for the three months ended March 31, 2021 that was included in the contract liability balance on December 31, 2020 was $155,558.

Cash and Restricted Cash—Our cash is comprised of highly liquid investments with maturities of three months or less. Restricted cash of $6,990 and $6,853 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at March 31, 2022 and December 31, 2021, respectively. This primarily represents cash deposited by the Company into separate accounts and designated as collateral for standby letters of credit in the same amount in accordance with contractual agreements.


3.			ACQUISITIONS

General—On December 30, 2021 (the “Closing Date”), Sterling completed the acquisition (the “Acquisition”) of Petillo LLC and its related entities (collectively, “Petillo”). The Acquisition is accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations.

Purchase Consideration—Sterling completed the Acquisition for a purchase price of $196,763, net of cash acquired, detailed as follows:


Cash consideration transferred, net of cash acquired	$	175,000
Equity consideration transferred (759 shares at $26.87 per share(1))	20,406

Target working capital adjustment	1,357
Total consideration	$	196,763

(1) Sterling’s closing stock price on December 29, 2021.

Preliminary Purchase Price Allocation—The aggregate purchase price noted above was allocated to the assets and liabilities acquired based upon their estimated fair values at the acquisition closing date, which were based, in part, upon a preliminary external appraisal and valuation of certain assets, including specifically identified intangible assets. The excess of the purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired totaling $60,339 was recorded as goodwill. This goodwill represents the value of expected future earnings and cash flows, as well as the synergies created by the integration of the new business within our organization, including cross-selling opportunities to help strengthen our existing service offerings and expand our market position. Goodwill and intangibles of approximately $130,000 related to the Acquisition, are deductible and amortizable for tax purposes over the next 15 years.

The following table summarizes our purchase price allocation at the Acquisition Closing Date, net of cash acquired:


Net tangible assets:
Accounts receivable	$	45,016
Contract assets	5,953
Other current assets	193
Property and equipment, net	48,175
Other non-current assets, net	5,498
Accounts payable	(21,810)
Contract liabilities	(8,585)
Other current liabilities	(8,216)
Total net tangible assets	66,224
Identifiable intangible assets	70,200
Goodwill	60,339
Total consideration transferred	$	196,763

During the three months ended March 31, 2022 the total consideration and purchase price allocation changed by $7,800, primarily due to an updated estimate of the tax basis step-up payment. The purchase price allocation above is subject to further change when additional information is obtained. We have not finalized our assessment of the fair values primarily for intangible assets and property and equipment. We intend to finalize the purchase price allocation as soon as practicable within the measurement period, but in no event later than one year following the Closing Date of the Acquisition. Our final purchase price allocation may result in additional adjustments to various other assets and liabilities, including the residual amount allocated to goodwill during the measurement period.

Identifiable Intangible Assets—Intangible assets identified as part of the Acquisition are reflected in the table below and are recorded at their estimated fair value, as determined by the Company’s management, based on available information which includes a preliminary valuation from external experts. The estimated useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to future cash flows.


	Weighted Average Life (Years)	December 30, 2021 Fair Value
Customer relationships	25	$	42,700
Trade names	25	27,500
Total		$	70,200

Supplemental Pro Forma Information (Unaudited)—The following unaudited pro forma combined financial information (“the pro forma financial information”) gives effect to the Acquisition, accounted for as a business combination using the purchase method of accounting. The pro forma financial information reflects the Acquisition and related events as if they occurred at the beginning of the period and includes adjustments to (1) include compensation expense associated with the employment agreement the Company entered into with Mr. Petillo, (2) include additional intangible asset amortization associated with the Acquisition, (3) include additional interest expense associated with the Acquisition and (4) include the pro forma results of Petillo for the period ending March 31, 2021. This pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated. Further, the pro forma financial information does not purport to project the future operating results of the combined company following the Acquisition.


	Three Months Ended
	March 31, 2021
Pro forma revenue	$	343,539
Pro forma net income attributable to Sterling	$	10,814


4.			REVENUE FROM CUSTOMERS

Backlog—The following table presents the Company’s backlog, by segment:


	March 31, 2022		December 31, 2021
E-Infrastructure Solutions Backlog	$	541,150	$	432,613
Transportation Solutions Backlog	898,679		963,267
Building Solutions Backlog - Commercial	87,055		97,235
Total Backlog	$	1,526,884	$	1,493,115

The Company expects to recognize approximately 68% of its backlog as revenue during the next twelve months, and the balance thereafter.

Revenue Disaggregation—The following tables present the Company’s revenue disaggregated by major end market and contract type:


	Three Months Ended March 31,
Revenues by major end market	2022		2021
E-Infrastructure Solutions Revenues	$	168,927	$	96,572
Heavy Highway	112,745		99,516
Aviation	17,583		27,222
Water Containment and Treatment	19,887		14,219
Other	10,284		6,097
Transportation Solutions Revenues	160,499		147,054
Residential	54,270		44,174
Commercial	26,624		27,516
Building Solutions Revenues	80,894		71,690
Total Revenues	$	410,320	$	315,316

Revenues by contract type
Fixed-Unit Price	$	156,310	$	177,547
Lump-Sum	197,868		91,155
Residential and Other	56,142		46,614
Total Revenues	$	410,320	$	315,316

Each of these contract types presents advantages and disadvantages. Typically, the Company assumes more risk with lump-sum contracts, however, these types of contracts offer additional profits if the work is completed for less than originally estimated. Under fixed-unit price contracts, the Company’s profit may vary if actual labor-hour costs vary significantly from the negotiated rates. Also, because some contracts can provide little or no fee for managing material costs, the components of contract cost can impact profitability.

Variable Consideration

The Company has projects that it is in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to the Company’s customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken. Based upon the Company’s review of the provisions of its contracts, specific costs incurred and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, the Company concluded it was appropriate to include in project price amounts of $13,985 and $13,905, at March 31, 2022 and December 31, 2021, respectively, relating to unapproved change orders and claims. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.

Contract Estimates

Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes such profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Changes in contract estimates and scope resulted in a net increase of $15,400 and $8,300 for the three months ended March 31, 2022 and 2021, respectively, included in “Operating income” on the Condensed Consolidated Statements of Operations.


5.			CONSOLIDATED 50% OWNED SUBSIDIARIES

The Company has 50% ownership interests in two subsidiaries (“Myers” and “RHB”) that it fully consolidates as a result of its exercise of control over the entities. The earnings attributable to the 50% portions the Company does not own were approximately $1,000 and $1,800 for the three months ended March 31, 2022 and 2021, respectively, and are eliminated within “Other operating expense, net” in the Condensed Consolidated Statements of Operations. Any undistributed earnings for partners are included in “Members’ interest subject to mandatory redemption and undistributed earnings” within the Condensed Consolidated Balance Sheets and are mandatorily payable at the time of the noncontrolling owners’ death or permanent disability.

These two subsidiaries have individual mandatory redemption provisions which, under circumstances outlined in the partner agreements, are certain to occur and obligate the Company to purchase each partner’s remaining 50% interests for $20,000 ($40,000 in the aggregate). The Company has purchased two separate $20,000 death and permanent total disability insurance policies to mitigate the Company’s cash draw if such events were to occur. These purchase obligations are also recorded in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets.

The liability consists of the following:


	March 31, 2022		December 31, 2021
Members’ interest subject to mandatory redemption	$	40,000	$	40,000
Net accumulated earnings	15,754		15,115
Total liability	$	55,754	$	55,115

The Company must determine whether any of its entities, including these two 50% owned subsidiaries, in which it participates, is a VIE. The Company determined that Myers is a VIE and that the Company is the primary beneficiary because, pursuant to the terms of the Myers Operating Agreement, the Company is exposed to the majority of potential losses of the partnership.

Summary financial information for Myers is as follows:


	Three Months Ended March 31,
	2022		2021
Revenues	$	44,358	$	27,957
Operating (loss) income	$	(1,448)	$	718
Net income	$	1,737	$	352


6.			CONSTRUCTION JOINT VENTURES

Joint Ventures with a Controlling Interest—We consolidate any venture that is determined to be a VIE for which we are the primary beneficiary, or which we otherwise effectively control. The equity held by the remaining owners and their portions of net income (loss) are reflected in stockholders’ equity on the Condensed Consolidated Balance Sheets line item “Noncontrolling interests” and in the Condensed Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests,” respectively. The Company determined that a joint venture in which the Company’s Ralph L. Wadsworth Construction subsidiary is a 51% owner is a VIE and the Company is the primary beneficiary. Summary financial information for this construction joint venture is as follows:


	Three Months Ended March 31,
	2022		2021
Revenues	$	7,853	$	8,242
Operating income	$	552	$	2,527
Net income	$	554	$	2,528

Joint Ventures with a Noncontrolling Interest—The Company accounts for unconsolidated joint ventures using a pro-rata basis in the Condensed Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Condensed Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry. Combined financial amounts of joint ventures in which the Company has a noncontrolling interest and the Company’s share of such amounts which are included in the Company’s Condensed Consolidated Financial Statements are shown below:


	March 31, 2022		December 31, 2021
Current assets	$	119,561	$	130,898
Current liabilities	$	(74,243)	$	(91,121)
Sterling’s receivables from and equity in construction joint ventures	$	19,292	$	16,896


	Three Months Ended March 31,
	2022		2021
Revenues	$	58,559	$	49,417
Income before tax	$	6,777	$	4,635
Sterling’s noncontrolling interest:
Revenues	$	26,608	$	21,944
Income before tax	$	3,067	$	2,135

The caption “Receivables from and equity in construction joint ventures” includes undistributed earnings and receivables owed to the Company. Undistributed earnings are typically released to the joint venture partners after the customer accepts the project as completed and the warranty period, if any, has passed.

Other—The use of joint ventures exposes us to a number of risks, including the risk that our partners may be unable or unwilling to provide their share of capital investment to fund the operations of the venture or complete their obligations to us, the venture, or ultimately, the customer. Differences in opinions or views among joint venture partners could also result in delayed decision-making or failure to agree on material issues, which could adversely affect the business and operations of the joint venture. In addition, agreement terms may subject us to joint and several liability for our venture partners, and the failure of our venture partners to perform their obligations could impose additional performance and financial obligations on us. The aforementioned factors could result in unanticipated costs to complete the projects, liquidated damages or contract disputes, including claims against our partners.


7.			PROPERTY AND EQUIPMENT

The Company’s intangible amortization expense was $3,568 and $2,866 for the three months ended March 31, 2022 and 2021, respectively.


9.			DEBT

The Company’s outstanding debt was as follows:


	March 31, 2022		December 31, 2021
Term Loan Facility	$	441,081	$	446,888
Revolving Credit Facility	—		—
Credit Facility	441,081		446,888

Other debt	11,441		15,309
Total debt	452,522		462,197
Less - Current maturities of long-term debt	(30,368)		(28,230)
Less - Unamortized debt issuance costs	(4,823)		(5,379)
Total long-term debt	$	417,331	$	428,588

Credit Facility—Our amended credit agreement (as amended, the “Credit Agreement”) provides the Company with senior secured debt financing (collectively, the “Credit Facility”) consisting of (i) a senior secured first lien term loan facility (the “Term Loan Facility”) in the aggregate principal amount of $540,000 and (ii) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of $75,000 (with a $75,000 limit for the issuance of letters of credit and a $15,000 sublimit for swing line loans). The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and interests of other parties. The Credit Facility will mature on October 2, 2024.

The Term Loan Facility bears interest at either the base rate plus a margin, or at a one to twelve-month LIBOR rate plus a margin, at the Company’s election. At March 31, 2022, the Company calculated interest using a one-month LIBOR rate and an applicable margin of 0.21% and 2.50% per annum, respectively. We continue to utilize an interest rate swap to hedge against $200,000 of the outstanding Term Loan Facility, which resulted in a weighted average interest rate of approximately 3.28% per annum during the three months ended March 31, 2022. Scheduled principal payments on the Term Loan Facility are made quarterly and total approximately $23,200, $31,900, and $26,100 for each of the years ending 2022, 2023 and 2024, respectively. A final payment of all principal and interest then outstanding on the Term Loan Facility is due on October 2, 2024. The Company is required to make mandatory prepayments on the Credit Facility with proceeds received from issuances of debt, events of loss and certain dispositions, and is also required to prepay the Credit Facility with a certain percentage of its excess cash flow within 5 days after receipt of its annual audited financial statements. For the three months ended March 31, 2022, the Company made scheduled term loan payments of $5,806.

The Revolving Credit Facility bears interest at the same rate options as the Term Loan Facility. In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the facility as well as letter of credit fees on outstanding instruments. At March 31, 2022, we had no outstanding borrowings under the $75,000 Revolving Credit Facility.

Debt Issuance Costs—The costs associated with the Credit Facility are reflected on the Condensed Consolidated Balance Sheets as a direct reduction from the related debt liability and amortized over the term of the facility. Amortization of debt

issuance costs was $556 and $660 for the three months ended March 31, 2022 and 2021, respectively, and was recorded as interest expense.

Other Debt—Other debt has primarily consisted of a $10,000 subordinated promissory note to one of the Plateau sellers and short-term Paycheck Protection Program loans (the “PPP Loans”) received by the Company’s two 50% owned subsidiaries. During the first quarter of 2022, the Small Business Administration forgave the final outstanding PPP Loan of approximately $4,800, of which the Company recorded a gain on debt extinguishment of $2,428 for its 50% portion of the gain.

Compliance and Other—The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict the ability of us and our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain certain financial covenants. As of March 31, 2022, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Condensed Consolidated Balance Sheets. At March 31, 2022 and December 31, 2021, the carrying values of our debt outstanding approximated the fair values.


10.			FINANCIAL INSTRUMENTS

Interest Rate Derivative—We continue to utilize a swap arrangement to hedge against interest rate variability associated with $200,000 of the $441,081 outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) (“OCI”) until the underlying hedged item is recognized in earnings. At March 31, 2022, the fair value of the swap recorded in accumulated other comprehensive income (loss) (“AOCI”) was a net loss of $210.

Derivatives Disclosures

Fair Value—Financial instruments are required to be categorized within a valuation hierarchy based upon the lowest level of input that is significant to the fair value measurement. The three levels of the valuation hierarchy are as follows:

•Level 1—Fair value is based on quoted prices in active markets.

•Level 2—Fair value is based on internally developed models that use, as their basis, readily observable market parameters. Our derivative positions are classified within level 2 of the valuation hierarchy as they are valued using quoted market prices for similar assets and liabilities in active markets. These level 2 derivatives are valued utilizing an income approach, which discounts future cash flow based on current market expectations and adjusts for credit risk.

•Level 3—Fair value is based on internally developed models that use, as their basis, significant unobservable market parameters. The Company did not have any level 3 classifications at March 31, 2022 or December 31, 2021.

The following table presents the fair value of the interest rate derivative by valuation hierarchy and balance sheet classification:


	March 31, 2022								December 31, 2021
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

12.			COMMITMENTS AND CONTINGENCIES

The Company is required by its insurance providers to obtain and hold standby letters of credit. These letters of credit serve as a guarantee by the banking institution to pay the Company’s insurance providers the incurred claim costs attributable to its general liability, workers’ compensation and automobile liability claims, up to the amount stated in the standby letters of credit, in the event that these claims were not paid by the Company. These letters of credit are cash collateralized, resulting in the cash being designated as restricted.

The Company, including its construction joint ventures and its consolidated 50% owned subsidiaries, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the Condensed Consolidated Financial Statements of the Company. There are no significant unresolved legal issues as of March 31, 2022.


13.			INCOME TAXES

The Company and its subsidiaries are based in the U.S. and file federal and various state income tax returns. The components of the provision for income taxes were as follows:


	Three Months Ended March 31,
	2022		2021
Current tax expense	$	957	$	618
Deferred tax expense	5,640		4,142
Income tax expense	$	6,597	$	4,760

Cash paid for income taxes	$	—	$	—

The effective income tax rate for three months ended March 31, 2022 was 25.3% and varied from the statutory rate primarily as a result of state income taxes, non-taxed PPP loan forgiveness, nondeductible compensation and other permanent differences.

Due to net operating loss carryforwards, the Company expects no cash payments for federal income taxes for 2022 or 2021. The Company makes cash payments for state income taxes in states in which the Company does not have net operating loss carry forwards.

At December 31, 2021 the Company had federal and state net operating loss (“NOL”) carryforwards of $33,780 and $32,064, respectively, which expire at various dates in the next 17 years for U.S. federal income tax and in the next 6 to 16 years for the various state jurisdictions where we operate. Such NOL carryforwards expire beginning in 2028 through 2039.

As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.


14.			STOCK INCENTIVE PLAN

General—The Company has a stock incentive plan (the “Stock Incentive Plan”) and an employee stock purchase plan (the “ESPP”) that are administered by the Compensation and Talent Development Committee of the Board of Directors. Under the Stock Incentive Plan, the Company can issue shares to employees and directors in the form of restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance share units (“PSUs”). Changes in common stock, additional paid in capital and treasury stock during the three months ended March 31, 2022 primarily relate to activity associated with the Stock Incentive Plan, the ESPP and shares withheld for taxes.

Share Grants—During the three months ended March 31, 2022, the Company granted the following awards under the Stock Incentive Plan:


	Shares	Weighted Average Grant-Date Fair Value per Share

RSUs	100	$	26.70
PSUs (at target)	154	$	26.82
Total shares granted	254

Share Issuances—During the three months ended March 31, 2022, the Company issued the following shares under the Stock Incentive Plan and the ESPP:


						Shares

RSUs (issued upon vesting)						5
PSUs (issued upon vesting)						675
ESPP (issued upon sale)						8
Total shares issued						688

Stock-Based Compensation—During the three months ended March 31, 2022 and 2021, the Company recognized $2,296 and $1,835, respectively, of stock-based compensation, primarily within general and administrative expenses. Included within total stock-based compensation for the three months ended March 31, 2022 and 2021 is $34 and $25, respectively, of expense related to the ESPP. Additionally, the Company has liability-based awards for which the number of units awarded is not determined until the vesting date. During the three months ended March 31, 2022 and 2021, the Company recognized $1,225 and $0, respectively, within additional paid in capital for the vesting of liability-based awards. The Company recognizes forfeitures as they occur, rather than estimating expected forfeitures.

Shares Withheld for Taxes—The Company withheld 263 shares for taxes on RSU/PSU stock-based compensation vestings for $7,385 during the three months ended March 31, 2022.

AOCI—During the three months ended March 31, 2022, changes in AOCI were a result of net gains (losses) recognized in OCI and amounts reclassified from AOCI into earnings related to our interest rate derivative. See Note 10 - Financial Instruments for further discussion.

17.			SEGMENT INFORMATION

The Company’s internal and public segment reporting are aligned based upon the services offered by its operating segments. With the December 30, 2021 acquisition of Petillo, the Company realigned its operating groups to reflect management’s present oversight of operations. After realignment, the Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions, and Building Solutions, with the commercial business reclassified from the previously reported Specialty Services operating group into the newly formed Building Solutions operating group. The segment information for the prior period has been recast to conform to the current presentation.

The Company’s Chief Operating Decision Maker evaluates the performance of the operating segment based upon revenue and income from operations. We incur expenses at the corporate level that relate to our business as a whole. Certain of these amounts have been charged to our business segments by various methods, largely on the basis of usage, with the unallocated remainder reported in the “Corporate” line. Corporate overhead is primarily comprised of corporate headquarters facility expense, the cost of the executive management team, and expenses pertaining to certain centralized functions that benefit the entire Company but are not directly attributable to the businesses, such as corporate human resources, legal, governance and finance functions.

The following table presents total revenue and income from operations by reportable segment for the three months ended March 31, 2022 and 2021:


	Three Months Ended March 31,
Revenues	2022		2021

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

Cautionary Statement Regarding Forward-Looking Statements

This quarterly report on Form 10-Q (“Report”) contains statements that are, or may be considered to be, “forward-looking statements” regarding the Company which represent our expectations and beliefs concerning future events. These forward-looking statements are intended to be covered by the safe harbor for certain forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements included herein relate to matters that are not based on historical facts and reflect our current expectations as of the date of this Report, regarding items such as: our industry and business outlook, including relating to federal, state and municipal funding for infrastructure projects, the residential home building market and demand from our customers; business strategy, including the integration of recent acquisitions and the potential for additional future acquisitions; expectations and estimates relating to our backlog; expectations concerning our market position; future operations; margins; profitability; capital expenditures; liquidity and capital resources; and other financial and operating information.

OVERVIEW

General—Sterling Construction Company, Inc. (“Sterling” or “the Company”) operates through a variety of subsidiaries within three segments specializing in E-Infrastructure, Transportation and Building Solutions in the United States (the “U.S.”), primarily across the Southern, Northeastern, Mid-Atlantic and the Rocky Mountain States, California and Hawaii, as well as other areas with strategic construction opportunities. E-Infrastructure Solutions projects develop advanced, large-scale site development systems and services for data centers, e-commerce distribution centers, warehousing, transportation, energy and more. Transportation Solutions includes infrastructure and rehabilitation projects for highways, roads, bridges, airports, ports, light rail, water, wastewater and storm drainage systems. Building Solutions projects include residential and commercial concrete foundations for single-family and multi-family homes, parking structures, elevated slabs and other concrete work. From strategy to operations, we are committed to sustainability by operating responsibly to safeguard and improve society’s quality of life. Caring for our people and our communities, our customers and our investors – that is The Sterling Way.

Petillo Acquisition—On December 30, 2021, we completed our acquisition of Petillo for aggregate consideration of $196.8 million. Petillo is a leading specialty site development contractor based in Flanders, New Jersey and serves the Northeastern and Mid-Atlantic States, providing large-scale site infrastructure improvement services, including full-service excavation, underground utility construction, environmental remediation, drainage systems for commercial construction and water management and distribution systems. The results of Petillo are included within our E-Infrastructure Solutions segment. See Note 3 - Acquisitions for further discussion.

Impact of COVID-19—The Company continues to monitor closely the actual and expected impacts of the COVID-19 pandemic on our business, financial condition and results of operations. To date, we have not experienced significant shutdowns of project sites or operational interruptions. While the Company has not incurred significant disruptions thus far from the COVID-19 pandemic, the pandemic may impact our business, condensed consolidated results of operations and financial condition in the future. The significance of impacts on our operations going forward is not yet certain and depends on numerous evolving factors as discussed further in the Company’s 2021 Form 10-K under “Part I, Item 1A. Risk Factors.”

MARKET OUTLOOK AND TRENDS

The market outlook and trends currently reflect favorable opportunities for long-term growth despite the challenging market pressures that include inflation, supply chain issues and labor challenges. To remain competitive in the current market environments, Sterling remains focused on our strategic business elements and objectives as outlined. We continue to shift our focus from low-bid heavy highway, that now represents approximately 14% of our total revenue, and increasing margins in our E-Infrastructure and Building Solutions segments.

E-Infrastructure Solutions—Sterling’s E-Infrastructure Solutions business is primarily driven by investments in the development of data centers, e-commerce distribution centers and warehouses. The continued revenue growth of the Company’s complex site development business is directly related to the continued implementation of publicly announced multi-year capital infrastructure campaigns from end users, including Amazon, Facebook and Home Depot. In our growing East Coast market, project activity includes data centers, new warehouse and industrial development. Within this market, the current warehouse availability rate is at 4.1%, despite over 16.7 million square feet of new building deliveries in 2021. Additionally, the market experienced over 11.8 million square feet of absorption during Q4, bringing 2021 total absorption to 34.5 million square feet, more than any other year on record. Equipment availability, material delays and fuel price increases continue to be challenging factors. With the forecasted increases expected in land prices, the customer trends show projects for full site development versus staged site development. The trend for full site development is expected to continue in 2022.

Transportation Solutions—Sterling’s Transportation Solutions business is primarily driven by federal, state and municipal funding. Federal funds, on average, provide 50% of annual State Department of Transportation capital outlays for highway and bridge projects. In October 2018, the Federal Aviation Administration reauthorized $3.35 billion annually through 2023. This reauthorization also includes more than $1 billion a year for airport infrastructure grants and about $1.7 billion for disaster relief. In November 2020, various state and local transportation measures were passed securing, and in some cases increasing, funding of major initiatives in Texas ($7.5 billion) and California ($520 million). On November 5, 2021 Congress passed the Infrastructure Investments and Jobs Act (“IIJA”) that provided a new five-year reauthorization of highway and public transportation programs with historic investment increases of $284 billion for all modes of transportation. With the passing of the IIJA, additional funding is reserved for transportation infrastructure with $110 billion reserved for roads and bridges, $66 billion for rail and $25 billion for airports. This bill could add additional multi-year funding for highways, rail and airports starting in 2022, however current changes for funding allocation may cause project start delays. Even though several of the states in Sterling’s key markets have instituted actions to further increase annual spending, shorter project cycles and continued fluctuations in pricing are causing delays in project awards.

Building Solutions—Our Building Solutions segment is comprised of our residential and commercial businesses. The continued revenue growth of our residential business is directly related to the growth of new home starts in its key market of Dallas-Fort Worth, the continued expansion in the Houston market, and the mid-2021 entry into the Phoenix market.

Residential’s core customer base is primarily made up of leading national home builders as well as regional and custom home builders. Over the last several quarters, the residential market has experienced significant price volatility and availability for key materials including concrete, steel and lumber, as well as increases in subcontractor labor cost. While the Company has worked with customers to pass on the increases in material and labor cost, the Company may not be successful in recouping these additional costs in the future. For our commercial business, the outlook for the multi-family market continues to decline, as developers face economic concerns due to the COVID-19 pandemic and the availability and affordability of starter single family homes continues to rise.

BACKLOG

Our backlog (“Backlog”) of construction projects is the remaining amount of contracts that we expect to recognize as revenue in future periods. The contracts in Backlog are typically completed in 6 to 36 months. Our unsigned low-bid awards (“Unsigned Low-bid Awards”) are excluded from Backlog until the contract is executed by our customer. We refer to the combination of our Backlog and Unsigned Low-bid Awards as “Combined Backlog.” Our book-to-burn ratio, a non-GAAP measure, is determined by taking our additions to Backlog and dividing it by revenue for the applicable period. This metric allows management to monitor the Company’s business development efforts to ensure we grow our Backlog and our business over time, and management believes that this measure is useful to investors for the same reason.

At March 31, 2022, our Backlog was $1.53 billion, as compared to $1.49 billion at December 31, 2021, with a book-to-burn ratio of 1.1X for the three months ended March 31, 2022.

Unsigned Low-bid Awards were $142.3 million at March 31, 2022 and $22.5 million at December 31, 2021. Combined Backlog totaled $1.67 billion and $1.52 billion at March 31, 2022 and December 31, 2021, with a book-to-burn ratio of 1.4X for the three months ended March 31, 2022.

The Company’s margin in Backlog has increased to 12.8% at March 31, 2022 from 12.2% at December 31, 2021 and the Combined Backlog margin increased to 12.6% at March 31, 2022 from 12.2% at December 31, 2021, driven by a greater mix of E-Infrastructure Solutions backlog.

RESULTS OF OPERATIONS

Consolidated Results

Summary—For the first quarter of 2022, the Company had operating income of $28.3 million, income before income taxes of $26.1 million, net income attributable to Sterling common stockholders of $19.3 million and net income per diluted share attributable to Sterling common stockholders of $0.64.

Consolidated financial highlights for the three months ended March 31, 2022 as compared to the three months ended March 31, 2021 are as follows:

Gross margin			13.7		%				14.3		%

Revenues—Revenues were $410.3 million for the first quarter of 2022, an increase of $95.0 million or 30.1% compared with the first quarter of 2021. The increase in the first quarter of 2022 was driven by a $72.4 million increase in E-Infrastructure Solutions (including $47.3 million from Petillo), a $13.4 million increase in Transportation Solutions and a $9.2 million increase in Building Solutions.

Gross profit—Gross profit was $56.1 million for the first quarter of 2022, an increase of $11.1 million or 24.7% compared to the first quarter of 2021. The Company’s gross margin as a percent of revenue decreased to 13.7% in the first quarter of 2022, as compared to 14.3% in the first quarter of 2021. The increase in gross profit and decrease in margin as a percent of revenue was primarily driven by higher volume, partly offset by continued headwinds from inflation, labor and material supply issues in E-Infrastructure Solutions and Building Solutions.

Contracts in progress which were not substantially completed totaled approximately 259 and 201 at March 31, 2022 and 2021, respectively. These contracts are of various sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion, the more visibility the Company has in refining its estimate of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus, gross profit as a percent of revenues can increase or decrease from comparable and subsequent quarters due to variations among contracts and depending upon the stage of completion of contracts.

General and administrative expenses—General and administrative expenses were $23.1 million, or 5.6% of revenue, for the first quarter of 2022, compared to $17.1 million, or 5.4% of revenue, for the first quarter of 2021. The increase was primarily driven by the inclusion of $3.1 million of general and administrative expense generated from Petillo operations in the first quarter of 2022, as well as a continued impact due to inflation and supply-chain issues. The Company anticipates that general and administrative expense will be approximately 5% of revenue for the full year 2022.

Interest expense—Interest expense was $4.6 million for the first quarter of 2022 compared to $6.0 million for the first quarter of 2021. The decrease is due to a 2% lower applicable interest rate provided under the amended Credit Agreement, which was amended in the second quarter of 2021. The decrease was partly offset by the additional borrowings related to the Petillo Acquisition.

Income taxes—The effective income tax rate was 25.3% for the first quarter of 2022. The effective income tax rate for first quarter of 2022 benefited primarily from the non-taxed PPP loan forgiveness. See Note 9 - Debt for more information. The Company anticipates an effective income tax rate for the full year 2022 of 28% to 29%. Due to its net operating loss carryforwards, the Company expects no cash payments for federal income taxes for 2022 or 2021. See Note 13 - Income Taxes for more information.

Segment Results

With the December 30, 2021 acquisition of Petillo, the Company realigned its operating groups to reflect management’s present oversight of operations. After realignment, the Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions, with the commercial business reclassified from the previously reported Specialty Services operating group into the newly formed Building Solutions operating group. The segment information for the prior period has been recast to conform to the current presentation.

E-Infrastructure Solutions

Revenues—Revenues were $168.9 million for the first quarter of 2022, an increase of $72.4 million or 74.9% compared to the first quarter of 2021. The increase was primarily driven by the inclusion of $47.3 million of revenue generated from Petillo operations in the first quarter of 2022, as well as higher volume.

Operating income—Operating income was $21.3 million for the first quarter of 2022, an increase of $3.5 million, compared to the first quarter of 2021. The increase was primarily driven by the inclusion of three months of operating income generated from Petillo operations in the first quarter of 2022, partly offset by continued headwinds from inflation, supply chain issues and the related impact on productivity and efficiency. The operating income and margin in the first quarter of 2022 were impacted by Petillo’s seasonality of weather in the Northeastern and Mid-Atlantic U.S. region.

Transportation Solutions

Revenues—Revenues were $160.5 million for the first quarter of 2022, an increase of $13.5 million or 9.1% compared to the first quarter of 2021. The increase was primarily driven by higher heavy highway, water containment and treatment and other revenue, partly offset by lower aviation revenue. The increase in heavy highway revenue was primarily due to the ramp up of construction on large design-build projects. During the first quarter of 2022, our low-bid heavy highway revenue decreased by $0.2 million, which was offset by an increase of $13.5 million from heavy highway design build and other revenues compared to the first quarter of 2021.

Operating Income—Operating income was $3.7 million for the first quarter of 2022, an increase of $1.0 million, compared to the first quarter of 2021. The increase was the result of improved margin mix with the ramp up of construction on large design-build projects and the continuation of our planned revenue reduction from lower margin low-bid heavy highway work.

Building Solutions

Revenues—Revenues were $80.9 million for the first quarter of 2022, an increase of $9.2 million or 12.8%, compared to the first quarter of 2021. The revenue increased due to a higher volume of slabs poured in the first quarter of 2022, compared to the first quarter of 2021. We continue to see strong demand for new housing in our Texas footprint and our expansion into the Arizona market.

Operating income—Operating income was $9.4 million for the first quarter of 2022, an increase of $2.0 million, compared to the first quarter of 2021. The increase in operating income and margin was driven by the aforementioned higher volume; however, operating margins have continued to be impacted by higher material costs for concrete, steel and lumber, and the lack of consistent availability of these materials, as well as labor shortages and increased subcontractor labor costs. While the Company continues to work with customers to pass on the increases in material and labor cost, the Company may not be successful in recouping these additional costs in the future.

Corporate

Operating expense—The corporate overhead element of general and administrative expenses, which is not allocated to the business segments, was $5.8 million for the first quarter of 2022, an increase of $0.7 million compared to the first quarter of 2021. Corporate overhead is primarily comprised of corporate headquarters facility expense, the cost of the executive management team, and expenses pertaining to certain centralized functions that benefit the entire Company but are not directly attributable to the businesses, such as corporate human resources, legal, governance and finance functions.

LIQUIDITY AND SOURCES OF CAPITAL

Cash—Cash at March 31, 2022, was $80.4 million, and includes the following components:


(In thousands)	March 31, 2022		December 31, 2021
Generally Available	$	40,251	$	29,812
Consolidated 50% Owned Subsidiaries	18,873		30,429
Construction Joint Ventures	21,271		21,599
Total Cash	$	80,395	$	81,840

The following tables set forth information about our cash flows and liquidity:


(In thousands)	Three Months Ended March 31,
Net cash provided by (used in):	2022		2021

Operating activities	$	19,183	$	38,090
Investing activities	(14,563)		(11,001)
Financing activities	(5,928)		(32,502)
Net change in cash and cash equivalents	$	(1,308)	$	(5,413)

Operating Activities—During the three months ended March 31, 2022, net cash provided by operating activities was $19.2 million compared to net cash provided by operating activities of $38.1 million in the three months ended March 31, 2021. Cash flows provided by operating activities were lower despite higher net income, after adjusting for various non-cash items and changes in accounts receivable, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below, and other accrued liabilities.

Changes in Contract Capital—The change in operating assets and liabilities varies due to fluctuations in operating activities and investments in Contract Capital. The changes in the components of Contract Capital during the three months ended March 31, 2022 and 2021 were as follows:


	Three Months Ended March 31,
(In thousands)	2022		2021


Contracts in progress, net	$	(16,305)	$	(7,921)
Accounts receivable	5,703		7,238
Receivables from and equity in construction joint ventures	(2,396)		(1,513)
Accounts payable	(2,876)		12,799
Change in Contract Capital, net	$	(15,874)	$	10,603

During the three months ended March 31, 2022, the change in Contract Capital decreased liquidity by $15.9 million. The Company’s Contract Capital fluctuations are impacted by the mix of projects in Backlog, seasonality, the timing of new awards and related payments for work performed and the contract billings to the customer as projects are completed. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts payable payments for projects.

Investing Activities—During the three months ended March 31, 2022, net cash used in investing activities was $14.6 million, compared to net cash used of $11.0 million in the three months ended March 31, 2021. The use of cash was driven by purchases of capital equipment less cash proceeds from the sale of property and equipment. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment.

Financing Activities—During the three months ended March 31, 2022, net cash used in financing activities was $5.9 million, compared to net cash used of $32.5 million in the prior year. The financing cash outflow was driven by $5.9 million of repayments on the Term Loan Facility.

Capital Strategy—The Company will continue to explore additional revenue growth and capital alternatives to improve leverage and strengthen its financial position in order to take advantage of trends in the civil infrastructure and E-infrastructure markets. The Company expects to pursue strategic uses of its cash, such as, investing in projects or businesses that meet its gross margin targets and overall profitability and managing its debt balances.

Inflation—While inflation did not have a material impact on our financial results for many years, beginning in 2021, supply chain volatility has resulted in price increases in oil, fuel, lumber, concrete and steel which have increased our cost of operations, and inflation has increased our general and administrative expense. Anticipated cost increases are considered in our bids to customers; however, inflation has had, and may continue to have, a negative impact on the Company’s financial results.

JOINT VENTURES

We participate in various construction joint venture partnerships in order to share expertise, risk and resources for certain highly complex projects. The joint venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of our partners was unable to pay its share, we would be fully liable for such share under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner’s inability to contribute additional funds to the venture in the event that the project incurred a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project

completion to which it committed in the joint venture agreement. See the 2021 Form 10-K under “Part I, Item 1A. Risk Factors.”

At March 31, 2022, there was approximately $231.5 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $98.6 million represented our proportionate share. Due to the joint and several liability under our joint venture arrangements, if one of our joint venture partners fails to perform, we and the remaining joint venture partners would be responsible for completion of the outstanding work. As of March 31, 2022, we are not aware of any situation that would require us to fulfill responsibilities of our joint venture partners pursuant to the joint and several liability under our contracts.

NEW ACCOUNTING STANDARDS

There have been no material changes to the Company’s discussion of new accounting standards from those described in Note 2 - Basis of Presentation and Significant Accounting Policies of our 2021 Form 10-K.

CRITICAL ACCOUNTING ESTIMATES

There have been no material changes to the Company’s discussion of critical accounting estimates from those described in Item 7 of our 2021 Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

We continue to utilize a swap arrangement to hedge against interest rate variability associated with $200 million of the $441 million outstanding under the Term Loan Facility. The Company has designated its interest rate swap agreement as a cash flow hedging derivative. To the extent the derivative instrument is effective and the documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. The total fair value of the contract was a net loss of approximately $0.2 million at March 31, 2022. For the $241 million remaining portion of the Term Loan Facility not associated with the interest rate swap hedge, at March 31, 2022 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest expense by approximately $2.4 million per year.

Other

The carrying values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. At March 31, 2022, the fair value of the term loan, based upon the current market rates for debt with similar credit risk and maturities, approximated its carrying value as interest is based on LIBOR plus an applicable margin.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures include, but are not limited to, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of March 31, 2022. As previously disclosed, we completed the Petillo and Kimes Acquisitions on December 30, 2021 and December 28, 2021, respectively, and, as permitted by SEC guidance for newly acquired businesses, we have elected to exclude the acquired operations of Petillo and Kimes from the scope of design and operation of our disclosure controls and procedures for the quarter ended March 31, 2022. Based on the evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective at March 31, 2022 to ensure that the information required to be disclosed by the Company in this Report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to the Company’s management including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

The Company, including its construction joint ventures and its consolidated 50% owned subsidiaries, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. The Company regularly analyzes current information about these proceedings and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters.

In the opinion of management, after consultation with legal counsel, there are currently no threatened or pending legal matters that would reasonably be expected to have a material adverse impact on the Company’s Consolidated Results of Operations, Financial Position or Cash Flows.

Item 1A. Risk Factors

There have not been any material changes from the risk factors previously disclosed in “Part I, Item 1A. Risk Factors” of the 2021 Form 10-K. You should carefully consider such risk factors, which could materially affect the business, financial condition or future results.
