What J's management wrote with each quarter's results: the press release (8-K item 2.02, exhibit 99) and, when the company files them, its prepared remarks or the call transcript. The call itself is not filed with SEC, so most quarters have the release only.

Adjusted vs GAAP earnings per share

in the company's own words

In its release of 2026-08-04, J reported $1.16 per share under GAAP and $1.84 on its own adjusted basis: the adjusted number is +59% above GAAP.

The company's words, latest release
GAAP EPS of $1.16 (vs. release
EPS of $1.56 in Q3 2025) with GAAP EPS reflecting a temporarily higher tax rate associated with the PA acquisition transaction; adjusted EPS 2 of $1.84 increased 13.6% y/y release

What the company says its adjusted numbers leave out:

The Company’s adjusted net earnings from continuing operations and adjusted EPS from continuing operations for the third quarter of fiscal 2026 and fiscal 2025 exclude certain adjustments that are further described in the section entitled “Non-GAAP Financial Measures” at the end of this release. release Aug 4, 2026

Both numbers are read from the words of each release (usually the highlights), never computed by us; hover a number for its sentence. Quarters where the release gives them only in a table are not shown. The company decides what "adjusted" leaves out; the full reconciliation is in the release.

Robust Q3 Gross Revenue and Adjusted Net Revenue Growth of 34% and 8% y/y, Respectively

Record Backlog of $28.9 billion, Up 27% y/y, with TTM Book-to-Bill Ratio of 1.4x (1.2x Adj. NR)

Engineering News-Record (ENR) Ranks Jacobs #1 in 18 Categories Including Data Centers, Up 6 y/y

Generated $456 million in Cash from Operations in Q3, Resulting in Strong Free Cash Flow

Raising FY 2026 Guidance for the Third Consecutive Quarter, Reflecting Strong Business Momentum DALLAS, TEXAS - Jacobs Solutions Inc. (NYSE: J) today announced its financial results for the fiscal third quarter ended June 26, 2026.

• Gross revenue of $4.1 billion up 34.5% y/y; adjusted net revenue 2 of $2.4 billion up 8.3% y/y

• GAAP net earnings of $137.4 million (vs. net earnings of $181.2 million in Q3 2025) with GAAP net earnings reflecting a temporarily higher tax rate associated with the PA acquisition transaction; adjusted EBITDA 2 of $366.8 million increased 16.7% y/y

• GAAP EPS of $1.16 (vs. EPS of $1.56 in Q3 2025) with GAAP EPS reflecting a temporarily higher tax rate associated with the PA acquisition transaction; adjusted EPS 2 of $1.84 increased 13.6% y/y

• Q3 book-to-bill of 1.5x (1.4x TTM); Q3 adjusted net revenue book-to-bill of 1.1x (1.2x TTM)

Jacobs' Chair and CEO Bob Pragada commented, “We delivered robust overall third quarter results driven by strength in Infrastructure & Advanced Facilities (I&AF) as segment gross revenue increased 39% year-on-year and adjusted net revenue increased 10% - all organic. Within I&AF, revenue growth was broad- based, led by the Data Center, Semiconductor, Energy & Power, Transportation and Water sectors. Our private sector and utility clients continue to boost capital spending, contributing to accelerating organic growth in our I&AF segment and record performance in our Life Sciences & Advanced Manufacturing end market. Importantly, we are seeing diversified revenue growth. The combination of strong execution, a record backlog position and a rising pipeline of opportunities across both I&AF and PA Consulting gives us confidence in our long-term trajectory. Focusing on FY26, we are raising the midpoints of our guidance for adjusted net revenue growth and adjusted EPS for the third consecutive time this year."

Jacobs' CFO Venk Nathamuni added, “We're very pleased with our Q3 performance. We are now well ahead of our initial FY26 expectations and remain on track to reach or exceed all of our FY29 targets. As spending on the AI build-out has ramped up, we have been able to leverage our cross-cutting portfolio of solutions to help deliver increasingly complex manufacturing and compute facilities. Top-tier revenue growth, paired with good operating performance, drove solid quarter-over-quarter improvement in our margin profile, which was further complemented by $456 million in reported cash generated from operating activities during Q3. The resulting increase in free cash flow helped reduce our net leverage to below our year-end target, even as we repurchased $614 million of our shares year-to-date. In summary, we are exiting Q3 in a very strong financial position with good momentum in our business as we prepare for the next fiscal year."

3 Reconciliation of fiscal 2026 adjusted EBITDA margin, adjusted EPS and expectations for adjusted net revenue growth and adjusted FCF margin to the most directly comparable GAAP measure is not available without unreasonable efforts because the Company cannot predict with sufficient certainty all the components required to provide such reconciliation, including with respect to the costs and charges relating to transaction expenses, restructuring and integration to be incurred in fiscal 2026. 2 The Company’s outlook for fiscal 2026 is for adjusted net revenue to grow 9.5% to 10.0% over fiscal 2025 (versus prior forecast of 8.0% to 10.5%), adjusted EBITDA margin to range from 14.7% to 14.8% (versus prior forecast of 14.6% to 14.9%), adjusted EPS to range from $7.20 to $7.30 (versus prior forecast of $7.10 to $7.35) and adjusted free cash flow margin to be approximately 8% (versus prior forecast of 7.0% to 8.5%). 3

In this press release, the Company has included certain non-GAAP financial measures as defined in Regulation G promulgated under the Securities Exchange Act of 1934, as amended. These non-GAAP measures are described below.

Adjusted net revenue is calculated by adjusting revenue from continuing operations to exclude amounts we bill to clients on projects where we are procuring subcontract labor or third-party materials and equipment on behalf of the client (referred to as “pass throughs”). These amounts are considered pass throughs because we receive no or only a minimal mark-up associated with the billed amounts. We sometimes refer to our GAAP revenue as "gross revenue."

Jacobs adjusted operating profit, adjusted earnings from continuing operations before taxes, adjusted income tax expenses from continuing operations, adjusted net earnings from continuing operations, adjusted EPS from continuing operations, adjusted earnings attributable to noncontrolling interests from continuing operations and adjusted interest expense from continuing operations are calculated by:

1. Excluding items collectively referred to as "Restructuring, Integration, Transaction and Other Charges," which include:

a. recoveries, costs and other charges associated with (i) restructuring activities, (ii) cost reduction initiatives implemented in connection with mergers, acquisitions, strategic investments, including the PA Consulting Transaction, and divestitures, including the separation of the CMS/C&I business, such as advisor fees, involuntary terminations and related costs, costs associated with co-locating offices of acquired companies, separating physical locations of continuing operations, professional services and other personnel costs, (iii) involuntary termination programs and other related separations impacting management and employees, including related transition costs, and (iv) certain legal costs and expenses to the extent related to (i) - (iii) or determined to not be related to continuing operations (clauses (i) – (iv) collectively referred to as “Restructuring, integration, separation and other charges"); and

b. transaction costs and other charges incurred in connection with mergers, acquisitions, strategic investments and divestitures, including advisor fees, change in control payments, the impact of the quarterly adjustment to the estimated performance based payout of contingent consideration to certain sellers in connection with certain acquisitions, certain consideration amounts resulting from the PA Consulting Transaction that represent compensation expense to be distributed to PA Consulting employees (including the removal of the associated tax impacts), loss on the foreign exchange forward contract in connection with the PA Consulting Transaction, amortization of the discount on the deferred consideration agreed upon as part of the PA Consulting Transaction and similar transaction costs and expenses (collectively referred to as "Transaction Costs").

2. Excluding items collectively referred to as "Other Adjustments", which include:

b. impact of certain subsidiary level contingent equity-based agreements in connection with the transaction structure of our March 2, 2021 PA Consulting investment. Under the terms of the applicable agreements, the remaining unvested portion of the relevant grants vested upon completion of the PA Consulting Transaction on March 20, 2026, resulting in expense which is also included as an adjustment;

c. certain tax adjustments resulting from activities directly related to the PA Consulting Transaction;

d. revenue under the Company's transition services agreement (TSA) included in other income for U.S. GAAP reporting purposes, and any SG&A costs associated with the provision of such services;

e. pretax mark-to-market and other related gains or losses associated with the Company's former investment in Amentum stock recorded in connection with the Separation Transaction;

f. discounts and expenses related to the one-time exchange of the Company's former investment in Amentum shares for a portion of the Company's outstanding term loans, which term loans were canceled;

g. impacts resulting from the EPS numerator adjustment relating to the redeemable noncontrolling interests preference share repurchase and reissuance activities; and

h. mark-to-market gains or losses associated with investments in equity securities carried at fair value.

We eliminate the impact of “Restructuring, Integration, Transaction and Other Charges” and "Other Adjustments" because we do not consider these to be indicative of ongoing operating performance. Actions taken by the Company to enhance 13 efficiencies are subject to significant fluctuations from period to period. The Company's management believes the exclusion of the amounts relating to the above-listed items improves the period-to-period comparability and analysis of the underlying financial performance of the business.

Adjustments to derive adjusted net earnings from continuing operations and adjusted EPS from continuing operations are calculated on an after-tax basis.

Free cash flow (FCF) is calculated as net cash provided by operating activities from continuing operations as reported on the statement of cash flows less additions to property and equipment. Adjusted FCF is calculated as reported FCF, calculated as previously described, adjusted to exclude employee-related payments which were included as part of the initial consideration paid in connection with the PA Consulting Transaction. Adjusted FCF Margin is calculated as Adjusted FCF divided by adjusted net revenue.

Adjusted EBITDA is calculated by adding income tax expense, depreciation expense and adjusted interest expense to, and deducting interest income from, adjusted net earnings attributable to Jacobs from continuing operations.

I&AF Operating Margin is a ratio of I&AF operating profit for the segment to the segment's adjusted net revenue. For a reconciliation of revenue to adjusted net revenue, see "Segment Information".

Jacobs Adjusted Operating Margin is a ratio of adjusted operating profit for the Company to the Company's adjusted net revenue. For a reconciliation of revenue to adjusted net revenue, see "Segment Information".

We believe that the measures listed above are useful to management, investors and other users of our financial information in evaluating the Company’s operating results and understanding the Company’s operating trends by excluding or adding back the effects of the items described above and below, the inclusion or exclusion of which can obscure underlying trends. Additionally, management uses such measures in its own evaluation of the Company’s performance, particularly when comparing performance to past periods, and believes these measures are useful for investors because they facilitate a comparison of our financial results from period to period.

This press release also contains certain financial and operating metrics which management believes are useful in evaluating the Company's performance. Backlog r epresents revenue or gross profit, as applicable, we expect to realize for work to be completed by our consolidated subsidiaries and our proportionate share of work to be performed by unconsolidated joint ventures. Gross margin in backlog refers to the ratio of gross profit in backlog to gross revenue in backlog . For more information on how we determine our backlog, see our Backlog Information in our most recent annual report filed with the Securities and Exchange Commission. Adjusted EBITDA margin refers to a ratio of adjusted EBITDA to adjusted net revenue. Book-to-bill ratio is an operational measure equal to the ratio of period bookings, less cancellations, to revenue. It is calculated as change in backlog during the reporting period plus revenue for the period, divided by revenue for the same period. Adjusted net revenue book-to-bill is calculated using the same methodology; however, the ratio uses adjusted net revenue for the period, which excludes pass-through revenue, added to the change in adjusted net revenue bookings, less cancellations, divided by adjusted net revenue. These metrics provide visibility into performance on business pursuits with and without pass-through revenue, which can be volatile from period to period. We regularly monitor these operating metrics to evaluate our business, identify trends affecting our business, and make strategic decisions.

The Company provides non-GAAP measures to supplement U.S. GAAP measures, as they provide additional insight into the Company’s financial results. However, non- GAAP measures have limitations as analytical tools and should not be considered in isolation and are not in accordance with, or a substitute for, U.S. GAAP measures. In addition, other companies may define non-GAAP measures differently, which limits the ability of investors to compare non-GAAP measures of the Company to those used by our peer companies.

The following tables reconcile non-GAAP financial measures used herein to their respective U.S. GAAP measures. For the comparable period presented below, the adjustments to derive the non-GAAP financial measures consist of amounts incurred in connection with the items described above. Amounts are shown in thousands, except for per-share data (note: earnings per share amounts may not total due to rounding). 14 Reconciliation of Earnings from Continuing Operations Before Taxes to Adjusted Earnings from Continuing Operations Attributable to Jacobs Before Taxes (in thousands)

DALLAS, TEXAS - Jacobs Solutions Inc. (NYSE: J) today announced its financial
results for the fiscal third quarter ended June 26, 2026.
                                                                                
  Q3 2026 Highlights                                                            
                                                                                
                                                                                
  1                                                                             
                                                                                
:

• Gross revenue of $4.1 billion up 34.5% y/y; adjusted net revenue 2 of $2.4
billion up 8.3% y/y

• GAAP net earnings of $137.4 million (vs. net earnings of $181.2 million in Q3
2025) with GAAP net earnings reflecting a temporarily higher tax rate associated
with the PA acquisition transaction; adjusted EBITDA 2 of $366.8 million
increased 16.7% y/y

• GAAP EPS of $1.16 (vs. EPS of $1.56 in Q3 2025) with GAAP EPS reflecting a
temporarily higher tax rate associated with the PA acquisition transaction;
adjusted EPS 2 of $1.84 increased 13.6% y/y

• Backlog of $28.9 billion up 27.3% y/y

• Q3 book-to-bill of 1.5x (1.4x TTM); Q3 adjusted net revenue book-to-bill of
1.1x (1.2x TTM)

Jacobs' Chair and CEO Bob Pragada commented, “We delivered robust overall third
quarter results driven by strength in Infrastructure & Advanced Facilities
(I&AF) as segment gross revenue increased 39% year-on-year and adjusted net
revenue increased 10% - all organic. Within I&AF, revenue growth was broad-
based, led by the Data Center, Semiconductor, Energy & Power, Transportation and
Water sectors. Our private sector and utility clients continue to boost capital
spending, contributing to accelerating organic growth in our I&AF segment and
record performance in our Life Sciences & Advanced Manufacturing end market.
Importantly, we are seeing diversified revenue growth. The combination of strong
execution, a record backlog position and a rising pipeline of opportunities
across both I&AF and PA Consulting gives us confidence in our long-term
trajectory. Focusing on FY26, we are raising the midpoints of our guidance for
adjusted net revenue growth and adjusted EPS for the third consecutive time this
year."

Jacobs' CFO Venk Nathamuni added, “We're very pleased with our Q3 performance.
We are now well ahead of our initial FY26 expectations and remain on track to
reach or exceed all of our FY29 targets. As spending on the AI build-out has
ramped up, we have been able to leverage our cross-cutting portfolio of
solutions to help deliver increasingly complex manufacturing and compute
facilities. Top-tier revenue growth, paired with good operating performance,
drove solid quarter-over-quarter improvement in our margin profile, which was
further complemented by $456 million in reported cash generated from operating
activities during Q3. The resulting increase in free cash flow helped reduce our
net leverage to below our year-end target, even as we repurchased $614 million
of our shares year-to-date. In summary, we are exiting Q3 in a very strong
financial position with good momentum in our business as we prepare for the next
fiscal year."

Reconciliations at the end of the press release for additional detail .

3 Reconciliation of fiscal 2026 adjusted EBITDA margin, adjusted EPS and
expectations for adjusted net revenue growth and adjusted FCF margin to the most
directly comparable GAAP measure is not available without unreasonable efforts
because the Company cannot predict with sufficient certainty all the components
required to provide such reconciliation, including with respect to the costs and
charges relating to transaction expenses, restructuring and integration to be
incurred in fiscal 2026.
                                       2                                        
The Company’s outlook for fiscal 2026 is for adjusted net revenue to grow 9.5%
to 10.0% over fiscal 2025 (versus prior forecast of 8.0% to 10.5%), adjusted
EBITDA margin to range from 14.7% to 14.8% (versus prior forecast of 14.6% to
14.9%), adjusted EPS to range from $7.20 to $7.30 (versus prior forecast of
$7.10 to $7.35) and adjusted free cash flow margin to be approximately 8%
(versus prior forecast of 7.0% to 8.5%).

▪ general economic conditions, including inflation and the actions taken by
monetary authorities in response to inflation, changes in interest rates and
foreign currency exchange rates, changes in capital markets and stock market
volatility, instability in the banking industry, labor shortages, or the impact
of a possible recession or economic downturn or changes to monetary or fiscal
policies or priorities in the U.S. and the countries where we do business on our
results, prospects and opportunities;

▪ competition from existing and future competitors in our target markets, as
well as the possible reduction in demand for certain of our product solutions
and services, including delays in the timing of the award of projects or
reduction in funding, or the abandonment of ongoing or anticipated projects due
to the financial condition of our clients and suppliers or due to governmental
budget constraints or changes to governmental budgetary priorities, or the
inability of our clients to meet their payment obligations in a timely manner or
at all;

▪ our ability to fully execute on our corporate strategy, including the impact
of acquisitions (including the transaction to acquire the remaining stake in PA
Consulting (the "PA Consulting Transaction"), strategic alliances, divestitures,
and other strategic events resulting from evolving business strategies,
including on our ability to maintain our culture and retain key personnel,
customers or suppliers, or our ability to achieve the cost-savings and synergies
contemplated by our recent acquisitions within the expected time frames or to
achieve them fully and to successfully integrate acquired businesses while
retaining key personnel, and our ability to invest in and effectively deploy and
use the tools, technologies and capabilities needed to implement our strategy,
including

artificial intelligence and other emerging technologies, and to manage the
operational, legal, regulatory, cybersecurity, data privacy and reputational
risks associated with the use of such technologies;

▪ financial market risks that may affect us, including by affecting our access
to capital, the cost of such capital and/or our funding obligations under
defined benefit pension and post-retirement plans;

▪ legislative changes, including potential changes to the amounts provided for
under the Infrastructure Investment and Jobs Act, as well as other legislation
and executive orders, including any directive to federal agencies to reduce
federal spending or the size of the federal workforce, and changes in U.S. or
foreign tax laws, including the tax legislation enacted in the U.S. in July
2025, statutes, rules, regulations or ordinances, including the impact of, and
changes to, tariffs and retaliatory tariffs or trade policies, that may
adversely impact our future financial position or results of operations;

▪ increased geopolitical uncertainty and risks, including policy risks and
potential civil unrest, relating to the outcome of elections across our key
markets and elevated geopolitical tension and conflicts, including the Russia-
Ukraine conflict and on-going, escalated and/or future tensions and conflicts in
the Middle East, among others; and

▪ the impact of any pandemic, and any resulting economic downturn on our
results, prospects and opportunities, measures or restrictions imposed by
governments and health officials in response to the pandemic, as well as the
inability of governments in certain of the countries in which we operate to
effectively mitigate the financial or other impacts of any future pandemics or
infectious disease outbreaks on their economies and workforces and our
operations therein.

The foregoing factors and potential future developments are inherently
uncertain, unpredictable and, in many cases, beyond our control. For a
description of these and additional factors that may occur that could cause
actual results to differ from our forward-looking statements see the Company’s
filings with the U.S. Securities and Exchange Commission, including in
particular the discussions contained in our fiscal 2025 Annual Report on Form
10-K under Item 1 - Business, Item 1A - Risk Factors, Item 3 - Legal
Proceedings, and Item 7 - Management's Discussion and Analysis of Financial
Condition and Results of Operations; and in our most recently filed Quarterly
Report on Form 10-Q under Part I, Item 2 - Management's Discussion and Analysis
of Financial Condition and Results of Operations. The Company is not under any
duty to update any of the forward-looking statements after the date of this
press release to conform to actual results, except as required by applicable
law.

   Non-GAAP Financial Measures and Operating Metrics:                           
                                                                                
In this press release, the Company has included certain non-GAAP financial
measures as defined in Regulation G promulgated under the Securities Exchange
Act of 1934, as amended. These non-GAAP measures are described below.

Adjusted net revenue is calculated by adjusting revenue from continuing
operations to exclude amounts we bill to clients on projects where we are
procuring subcontract labor or third-party materials and equipment on behalf of
the client (referred to as “pass throughs”). These amounts are considered pass
throughs because we receive no or only a minimal mark-up associated with the
billed amounts. We sometimes refer to our GAAP revenue as "gross revenue."

Jacobs adjusted operating profit, adjusted earnings from continuing operations
before taxes, adjusted income tax expenses from continuing operations, adjusted
net earnings from continuing operations, adjusted EPS from continuing
operations, adjusted earnings attributable to noncontrolling interests from
continuing operations and adjusted interest expense from continuing operations
are calculated by:

1. Excluding items collectively referred to as "Restructuring, Integration,
Transaction and Other Charges," which include:

a. recoveries, costs and other charges associated with (i) restructuring
activities, (ii) cost reduction initiatives implemented in connection with
mergers, acquisitions, strategic investments, including the PA Consulting
Transaction, and divestitures, including the separation of the CMS/C&I business,
such as advisor fees, involuntary terminations and related costs, costs
associated with co-locating offices of acquired companies, separating physical
locations of continuing operations, professional services and other personnel
costs, (iii) involuntary termination programs and other related separations
impacting management and employees, including related transition costs, and (iv)
certain legal costs and expenses to the extent related to (i) - (iii) or
determined to not be related to continuing operations (clauses (i) – (iv)
collectively referred to as “Restructuring, integration, separation and other
charges"); and

b. transaction costs and other charges incurred in connection with mergers,
acquisitions, strategic investments and divestitures, including advisor fees,
change in control payments, the impact of the quarterly adjustment to the
estimated performance based payout of contingent consideration to certain
sellers in connection with certain acquisitions, certain consideration amounts
resulting from the PA Consulting Transaction that represent compensation expense
to be distributed to PA Consulting employees (including the removal of the
associated tax impacts), loss on the foreign exchange forward contract in
connection with the PA Consulting Transaction, amortization of the discount on
the deferred consideration agreed upon as part of the PA Consulting Transaction
and similar transaction costs and expenses (collectively referred to as
"Transaction Costs").

2. Excluding items collectively referred to as "Other Adjustments", which
include:

a. intangible assets amortization and impairment charges;

b. impact of certain subsidiary level contingent equity-based agreements in
connection with the transaction structure of our March 2, 2021 PA Consulting
investment. Under the terms of the applicable agreements, the remaining unvested
portion of the relevant grants vested upon completion of the PA Consulting
Transaction on March 20, 2026, resulting in expense which is also included as an
adjustment;

c. certain tax adjustments resulting from activities directly related to the PA
Consulting Transaction;

d. revenue under the Company's transition services agreement (TSA) included in
other income for U.S. GAAP reporting purposes, and any SG&A costs associated
with the provision of such services;

e. pretax mark-to-market and other related gains or losses associated with the
Company's former investment in Amentum stock recorded in connection with the
Separation Transaction;

f. discounts and expenses related to the one-time exchange of the Company's
former investment in Amentum shares for a portion of the Company's outstanding
term loans, which term loans were canceled;

g. impacts resulting from the EPS numerator adjustment relating to the
redeemable noncontrolling interests preference share repurchase and reissuance
activities; and

h. mark-to-market gains or losses associated with investments in equity
securities carried at fair value.

We eliminate the impact of “Restructuring, Integration, Transaction and Other
Charges” and "Other Adjustments" because we do not consider these to be
indicative of ongoing operating performance. Actions taken by the Company to
enhance
                                       13                                       
efficiencies are subject to significant fluctuations from period to period. The
Company's management believes the exclusion of the amounts relating to the
above-listed items improves the period-to-period comparability and analysis of
the underlying financial performance of the business.

Adjustments to derive adjusted net earnings from continuing operations and
adjusted EPS from continuing operations are calculated on an after-tax basis.

Free cash flow (FCF) is calculated as net cash provided by operating activities
from continuing operations as reported on the statement of cash flows less
additions to property and equipment. Adjusted FCF is calculated as reported FCF,
calculated as previously described, adjusted to exclude employee-related
payments which were included as part of the initial consideration paid in
connection with the PA Consulting Transaction. Adjusted FCF Margin is calculated
as Adjusted FCF divided by adjusted net revenue.

Adjusted EBITDA is calculated by adding income tax expense, depreciation expense
and adjusted interest expense to, and deducting interest income from, adjusted
net earnings attributable to Jacobs from continuing operations.

I&AF Operating Margin is a ratio of I&AF operating profit for the segment to the
segment's adjusted net revenue. For a reconciliation of revenue to adjusted net
revenue, see "Segment Information".

Jacobs Adjusted Operating Margin is a ratio of adjusted operating profit for the
Company to the Company's adjusted net revenue. For a reconciliation of revenue
to adjusted net revenue, see "Segment Information".

We believe that the measures listed above are useful to management, investors
and other users of our financial information in evaluating the Company’s
operating results and understanding the Company’s operating trends by excluding
or adding back the effects of the items described above and below, the inclusion
or exclusion of which can obscure underlying trends. Additionally, management
uses such measures in its own evaluation of the Company’s performance,
particularly when comparing performance to past periods, and believes these
measures are useful for investors because they facilitate a comparison of our
financial results from period to period.

This press release also contains certain financial and operating metrics which
management believes are useful in evaluating the Company's performance. Backlog
r epresents revenue or gross profit, as applicable, we expect to realize for
work to be completed by our consolidated subsidiaries and our proportionate
share of work to be performed by unconsolidated joint ventures. Gross margin in
backlog refers to the ratio of gross profit in backlog to gross revenue in
backlog . For more information on how we determine our backlog, see our Backlog
Information in our most recent annual report filed with the Securities and
Exchange Commission. Adjusted EBITDA margin refers to a ratio of adjusted EBITDA
to adjusted net revenue. Book-to-bill ratio is an operational measure equal to
the ratio of period bookings, less cancellations, to revenue. It is calculated
as change in backlog during the reporting period plus revenue for the period,
divided by revenue for the same period. Adjusted net revenue book-to-bill is
calculated using the same methodology; however, the ratio uses adjusted net
revenue for the period, which excludes pass-through revenue, added to the change
in adjusted net revenue bookings, less cancellations, divided by adjusted net
revenue. These metrics provide visibility into performance on business pursuits
with and without pass-through revenue, which can be volatile from period to
period. We regularly monitor these operating metrics to evaluate our business,
identify trends affecting our business, and make strategic decisions.

The Company provides non-GAAP measures to supplement U.S. GAAP measures, as they
provide additional insight into the Company’s financial results. However, non-
GAAP measures have limitations as analytical tools and should not be considered
in isolation and are not in accordance with, or a substitute for, U.S. GAAP
measures. In addition, other companies may define non-GAAP measures differently,
which limits the ability of investors to compare non-GAAP measures of the
Company to those used by our peer companies.

The following tables reconcile non-GAAP financial measures used herein to their
respective U.S. GAAP measures. For the comparable period presented below, the
adjustments to derive the non-GAAP financial measures consist of amounts
incurred in connection with the items described above. Amounts are shown in
thousands, except for per-share data (note: earnings per share amounts may not
total due to rounding).
