The Company’s GCR projects tend to be built over a 12- to 24-month schedule depending upon scope and complexity. Most major projects have a preconstruction planning phase, which may require months of planning before actual construction commences. The Company is occasionally employed to deliver a “fast-track” project, where construction commences as the preconstruction planning work continues. As work on the Company’s projects progress, it increases or decreases backlog to take into account its estimate of the effects of changes in estimated quantities, changes in conditions, change orders and other variations from initially anticipated contract revenue, and the percentage of completion of the Company’s work on the projects. Based on historical trends, the Company currently estimates that 83% of its GCR backlog as of December 31, 2023 will be recognized as revenue during 2024. Additionally, the reduction in GCR backlog has been intentional as the Company looks to focus on higher margin projects than historically, as well as its focus on smaller, higher margin owner direct projects.

Current wording

The Company’s GCR backlog was $140.0 million and $186.9 million as of December 31, 2024 and 2023, respectively.

Previous wording

Although the Company has been experiencing strong demand, certain events continue to impact its business, including global economic conditions, the inflationary cost environment, elevated labor costs, disruption in its supply chain, continued uncertainty around the COVID-19 pandemic and ongoing geopolitical instability caused by conflicts in Ukraine and the Middle East. The Company continued to experience elevated levels of cost inflation during 2023, which is expected to persist through 2024, although at lower levels than experienced in 2023. These headwinds have been partially mitigated in 2023 by pricing actions taken in response to the inflationary cost environment, supply chain productivity improvements and cost savings initiatives. The effects of inflation also have resulted in central banks raising short-term interest rates and, therefore, the Company has experienced an increase in its interest expense relative to its outstanding borrowings. While the impacts of COVID-19 on the Company's business have moderated, there still remains uncertainty around the pandemic, its effect on labor or other macroeconomic factors, its severity and duration, the continued availability and effectiveness of vaccines and actions taken by third parties or by government authorities in response, including restrictions, laws or regulations, or other responses. Also, the ongoing conflict between Russia and Ukraine, and the sanctions imposed in response to this conflict, have increased global economic and political uncertainty and the conflict in the Middle East may add to these issues.

Current wording

In 2024, the mechanical services industry experienced steady demand across key sectors, driven by continued investment in energy efficiency, infrastructure upgrades and maintenance of aging mechanical systems. However, the industry faced challenges related to economic uncertainty, labor shortages and supply chain volatility. Although the Company has been experiencing strong demand, these industry challenges continue to impact its business. The Company experienced elevated levels of cost inflation during 2023, which has continued into 2024, although at lower levels than those experienced in 2023. These headwinds have been partially mitigated in 2023 and 2024 by pricing actions taken in response to the inflationary cost environment, supply chain productivity improvements and cost savings initiatives. Economic conditions contributed to increases in interest rates during 2023; however, interest rates remained stable in the first half of 2024 and the Federal Reserve reduced its benchmark interest rate by a total of 100 basis points in the second half of 2024. Future interest rate changes would raise or lower the rates the Company pays on its leased fleet vehicles and borrowings under the Second A&R Wintrust Revolving Loan. However, the Company is party to an interest rate swap arrangement to manage the risk associated with a portion of its variable-rate revolving loan. Also, the ongoing conflict between Russia and Ukraine, and the sanctions imposed in response to this conflict, have increased global economic and political uncertainty and the conflict in the Middle East may add to these issues.

Previous wording

While the impact of these factors remains uncertain, the Company continues to evaluate the extent to which they may impact its business, financial condition or results of operations. There can be no assurance that the Company's actions will serve to mitigate such impacts in future periods. Further, while the Company believes its remaining performance obligations are firm, and its customers have not provided the Company with indications that they no longer wish to proceed with planned projects, prolonged delays in the receipt of critical equipment could result in the Company's customers seeking to terminate existing or pending agreements. Any of these events could have a material adverse effect on the Company’s business, financial condition and/or results of operations.

Current wording

While the impact of these factors remains uncertain, the Company continues to evaluate the extent to which they may impact its business, financial condition or results of operations. There can be no assurance that the Company's actions will serve to mitigate such impacts in future periods. In periods of economic uncertainty, businesses and organizations may delay or cancel large capital projects, such as new construction or major mechanical system upgrades. The Company’s service contracts and maintenance work often remain stable or even increase, as customers prioritize maintaining existing systems over capital-intensive replacements. Further, economic downturns may lead to increased competition and pricing pressures, impacting revenue and margins. The Company believes that its diversified service offerings reduce its exposure to market volatility. While the Company believes its remaining performance obligations are firm, and its customers have not provided the Company with indications that they no longer wish to proceed with planned projects, prolonged delays in the receipt of critical equipment could result in the Company's customers seeking to terminate existing or pending agreements. Any of these events could have a material adverse effect on the Company’s business, financial condition and/or results of operations.

Previous wording

In the Company’s GCR segment, its efforts continue to focus on improving project execution and profitability by pursuing opportunities that are smaller in size and shorter in duration than historically, and where it can leverage its captive design and engineering services. The Company believes that it is appropriate in the current contracting environment to reduce risk and exposure to large, complex, non-owner direct projects where the trend has been for such jobs to provide risks that are difficult to mitigate. Currently, management believes the historical industry pricing and associated risks for this type of work does not align with the Company’s stakeholders’ expectations, and therefore, the Company continues to take steps to actively reduce these risks as it looks at future job selection and as it completes current jobs.

Previous wording

The prices of products such as steel, pipe, copper and equipment from manufacturers are subject to fluctuation and increases. It is difficult to accurately measure the impact of inflation, tariffs and price escalation due to the imprecise nature of the estimates required. However, these effects are, at times, material to the Company’s results of operations and financial condition. During fiscal years 2023 and 2022, the Company experienced higher cost of materials on specific projects and delays in its supply chain for equipment and service vehicles from the manufacturers, and it expects these higher costs and delays in its supply chain to persist in 2024. When appropriate, the Company includes cost escalation factors into its bids and proposals, as well as limit the acceptance time of its bid. In addition, the Company is often able to mitigate the impact of future price increases by entering into fixed price purchase orders for materials and equipment and subcontracts on its projects. Notwithstanding these efforts, if the Company experiences significant disruptions to its supply chain, it may need to delay certain projects that would otherwise be accretive to its business, and this may also impact the conversion rate of its current backlog into revenue.

Previous wording

The increase in operating cash flows during the year ended December 31, 2023 compared to the year ended December 31, 2022 was primarily attributable to a $68.0 million period-over-period cash inflow related to the change in accounts receivable, which was due to the timing of cash receipts, inclusive of an aggregate $25.6 million in cash receipts associated with certain outstanding claim resolutions. This cash inflow was partially offset by a $38.4 million cash outflow period-over-period related to the aggregate change in the Company’s contract assets and liabilities and a $22.2 million change in accounts payable, including retainage. The increase in the Company’s overbilled position was due to the timing of contract billings and the recognition of contract revenue, as well as the successful resolution of certain outstanding claims. The cash outflows associated with its accounts payable were due to the timing of cash receipts and payments.

Current wording

The decrease in operating cash flows during the year ended December 31, 2024 compared to the year ended December 31, 2023 was primarily attributable to a $43.9 million year-over-year cash outflow related to the change in accounts receivable, which was due to the timing of cash receipts and the successful resolution of certain outstanding claims recognized in 2023. This cash outflow was partially offset by a $10.1 million increase in net income, a $6.2 million increase related to non-cash operating activities and an aggregate $4.3 million period-over-period change related to the Company’s contract assets and liabilities. The increase in the Company’s overbilled position was due to the timing of contract billings and the recognition of contract revenue.
