Description of Business one During the fourth 2021, first 2022 , 2, third 2022 , no no December 31, 2021, In alphabetical order, our business operating groups are as follows: • California, which is comprised of vertically integrated businesses in home markets across the state; • Central, which includes the vertically integrated Arizona region and regional civil construction businesses in Illinois, Florida and Texas. The Central group also includes the Federal division which performs civil construction across the continental United States and Guam, and the Tunnel division; and • Mountain, which is comprised of vertically integrated regional businesses in Alaska, Washington, Oregon, Utah and Nevada. The Mountain Group also includes national businesses in the Industrial & Energy division, which primarily focuses on commercial solar construction projects, Water Resources, which performs water well drilling and rehabilitation services and Mineral Services, which performs mineral exploration services for mining clients. Principles of Consolidation may 810, Consolidation may not two no no If we have determined we are not one 323, Investments - Equity Method and Joint Ventures, We also participate in “line-item” joint venture agreements under which each partner is responsible for performing certain discrete items of the total scope of contracted work. The revenue for each line-item joint venture partners’ discrete items of work is defined in the contract with the project owner and each joint venture partner bears the profitability risk associated only with its own work.

Recognize revenue Generally, our contracts contain one may not The transaction price is the amount of consideration to which we expect to be entitled in exchange for transferring goods and services to the customer. The contractual consideration from customers of our Construction segment may not one Subsequent to the inception of a contract in our Construction segment, the transaction price could change for various reasons, including executed or unapproved change orders, and unresolved contract modifications and/or affirmative claims. Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and/or affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which the Company believes it is entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third may may Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the estimated recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not Generally, performance obligations related to contracts in our Construction segment are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to revisions in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost.

Changes that are accounted for as an adjustment to existing performance obligations are allocated on the same basis at contract inception. Otherwise, changes are accounted for as separate performance obligation(s) and the separate transaction price is allocated as discussed above. Changes are made to the transaction price from unapproved change orders to the extent the amount can be reasonably estimated and recovery is probable. On certain projects we have submitted and have pending unresolved contract modifications and/or affirmative claims (“affirmative claims”) to recover additional costs and the associated profit, if applicable, to which the Company believes it is entitled under the terms of contracts with customers, subcontractors, vendors or others. The owners or their authorized representatives and/or other third may may Changes are made to the transaction price from affirmative claims with customers to the extent that additional revenue on a claim settlement with a customer is probable and estimable. A reduction to costs related to affirmative claims with non-customers with whom we have a contractual arrangement (“back charges”) is recognized when the estimated recovery is probable and estimable. Recognizing affirmative claims and back charge recoveries requires significant judgments of certain factors including, but not Generally, performance obligations related to contracts in our Construction segment are satisfied over time because our performance typically creates or enhances an asset that the customer controls as the asset is created or enhanced. We recognize revenue as performance obligations are satisfied and control of the promised good and/or service is transferred to the customer. Revenue in our Construction segment is ordinarily recognized over time as control is transferred to the customers by measuring the progress toward complete satisfaction of the performance obligation(s) using an input (i.e., “cost to cost”) method. Under the cost to cost method, costs incurred to-date are generally the best depiction of transfer of control. All contract costs, including those associated with affirmative claims, change orders and back charges, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract costs consist of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the forecasted revenue and cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach. There are a number of factors that can contribute to revisions in estimates of contract cost and profitability. The most significant of these include: • changes in costs of labor and/or materials; • subcontractor costs, availability and/or performance issues; • extended overhead and other costs due to owner, weather and other delays; • changes in productivity expectations; • changes from original design on design-build projects; • our ability to fully and promptly recover on affirmative claims and back charges for additional contract costs; • a change in the availability and proximity of equipment and materials; • complexity in original design; • length of time to complete the project; • the availability and skill level of workers in the geographic location of the project; • site conditions that differ from those assumed in the original bid; • costs associated with scope changes; and • the customer’s ability to properly administer the contract. The foregoing factors, as well as the stage of completion of contracts in process and the mix of contracts at different margins may All state and federal government contracts and many of our other contracts provide for termination of the contract at the convenience of the party contracting with us, with provisions to pay us for work performed through the date of termination including demobilization cost.

[1]Beginning in 2022, with the adoption of ASU 2020-06, we have applied the if-converted method for calculating diluted earnings per share (see Note 1).[2]Due to the net losses for the year ended December 31, 2020, RSUs representing approximately 589,000 shares, respectively, have been excluded from the number of shares used in calculating diluted net income (loss) per share, as their inclusion would be antidilutive.[3]The number of shares used in calculating diluted net income per share for the year ended December 31, 2020, excluded potential dilution from the 2.75% Convertible Notes converting into shares of common stock since the average stock price did not exceed $31.47.
