FOR IMMEDIATE RELEASE

Williams Reports Second Quarter 2021 Financial Results

Backlog $664.4 Million; Revenue Growth 26.2%; EPS $0.11

ATLANTA, GA, August 18, 2021 – Williams Industrial Services Group Inc. (NYSE American: WLMS) (“Williams” or the “Company”), an energy and industrial infrastructure services company, today reported its financial results for the fiscal second quarter ended June 30, 2021.

Recent Highlights

● Williams posted revenue of $91.6 million in the second quarter of 2021, an increase of 26.2% year-over-year,  compared with $72.5 million in the prior-year period

● The Company reported net income of $2.9 million, an increase of 14.6% year-over-year, or $0.11 per share, in the second quarter versus net income of $2.5 million, or $0.10 per share, in the second quarter of 2020

● Adjusted EBITDA¹ was $4.9 million for the second quarter of 2021 compared with $5.0 million in the prior-year period

● As of June 30, 2021, the Company’s backlog was $664.4 million, an increase of 44.2%, compared to $460.6 million as of March 31, 2021, with approximately $199.5 million expected to be converted to revenue over the following twelve months and $123.4 million expected to be converted by the end of the fiscal year

● The Company announced on June 1, 2021 that it had been granted an expansion of its nuclear decommissioning scope with Holtec and CDI with the addition of three units at the Indian Point Energy Center (“IPEC”), a multi-year project increase

“I’m pleased to report that Williams’ second quarter results met our expectations,” said Tracy Pagliara, President and CEO of Williams. “Revenue rose 26% year-over-year, while our backlog climbed over $200 million from the end of the first quarter. We are successfully expanding existing customer relationships and are actively engaged in new business development initiatives that leverage our role as a leading, respected provider of infrastructure services across the energy and industrial end markets. This is enabling us to further strengthen our core nuclear business while continuing to diversify into adjacent areas, positioning Williams for the bright future envisioned by our strategic plan. Given the Company’s performance, we are once again reaffirming our prior financial guidance for 2021 and believe we are on track for even greater results in 2022 and beyond.”  

Second Quarter 2021 Financial Results Compared to Second Quarter 2020

Revenue in the second quarter of 2021 was $91.6 million compared with $72.5 million in the second quarter of 2020, reflecting higher revenue across a broad range of the Company’s customers, more than offsetting $12.3 million of lower revenue tied to the Vogtle 3 & 4 nuclear construction project.

Gross profit was $9.4 million, or 10.2% of revenue, compared with $9.4 million, or 12.9% of revenue, in the prior-year period, with the lower margin reflecting changes in project mix and lower Vogtle-related work. Gross margins in the second quarter of 2021 were also impacted by the timing of a contract incentive related to a multi-year customer contract. The incentive related to the second quarter of 2020 was earned and recorded in the second quarter of 2020 for $1.1 million; the incentive related to

2021 is anticipated to be recorded in the third quarter. Operating expenses were $6.6 million compared with $5.6 million in the second quarter of 2020, reflecting investment in new business developmentand an increase in stock compensation expense. The Company reported operating income of $2.7 million versus $3.8 million in the prior-year period. Interest expense was $1.2 million in the second quarter of 2021 versus $1.6 million in 2020, as a result of the Company’s refinancing which was completed in the fourth quarter of 2020.

The Company reported net income of $2.9 million, or $0.11 per share, in the second quarter of 2021 compared with net income of $2.5 million, or $0.10 per share, in the prior-year period.

Balance Sheet

Total liquidity (the sum of unrestricted cash and availability under the Revolving Credit Facility) was $20.6 million at the end of the second quarter. The Company anticipates using its cash generation, supported by significant net operating losses (NOLs), to lower indebtedness during the remainder of fiscal 2021. As of June 30, 2021, the Company had $7.7 million of unrestricted cash and cash equivalents, $0.5 million of restricted cash, and $33.6 million of bank debt compared with $8.7 million of unrestricted cash and cash equivalents, $0.5 million of restricted cash, and $32.1 million of bank debt as of December 31, 2020.

Backlog

Total backlog as of June 30, 2021 was $664.4 million compared with $460.6 million on March 31, 2021. The Company recognized revenue of $91.6 million in the second quarter, booked new awards of $262.2 million, and saw net adjustments and cancellations of $33.2 million, primarily reflecting work scope expansion.

	Three Months Ended June 30, 2021		Six Months Ended June 30, 2021
Backlog - beginning of period	$	460,550	$	443,850
New awards		262,213		299,454

Revenue recognized		(91,571)		(152,422)
Backlog - end of period	$	664,357	$	664,357

Williams estimates that approximately $199.5 million, or 30.0% of total backlog, will be converted to revenue in the following twelve months and $123.4 million, or 18.6%, of total backlog, will be converted to revenue within the remainder of the fiscal year. This compares with $182.4 million of backlog on March 31, 2021 that the Company anticipated would be converted to revenue over the succeeding twelve-month period.

NOTE 1 — Non-GAAP Financial Measures

Adjusted EBITDA-Continuing Operations

Adjusted EBITDA is not calculated through the application of GAAP and is not the required form of disclosure by the U.S. Securities and Exchange Commission. Adjusted EBITDA is the sum of the Company’s income (loss) from continuing operations before interest expense, net, and income tax (benefit) expense and unusual gains or charges. It also excludes non-cash charges such as depreciation and amortization. The Company’s management believes adjusted EBITDA is an important measure of operating performance because it allows management, investors and others to evaluate and compare the performance of its core operations from period to period by removing the impact of the capital structure (interest), tangible and intangible asset base (depreciation and amortization), taxes and unusual gains or charges (stock-based compensation, other professional fees, franchise taxes, foreign currency (gain) loss, and settlement expenses), which are not always commensurate with the reporting period in which such items are included. Williams’ credit facilities also contain ratios based on EBITDA. Adjusted EBITDA should not be considered an alternative to net income or as a better measure of liquidity than net cash flows from operating activities, as determined by GAAP, and, therefore, should not be used in isolation from, but in conjunction with, the GAAP measures. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.

Note Regarding Forward-Looking Non-GAAP Financial Measures

The Company does not provide a reconciliation of forward-looking non-GAAP financial measures to their comparable GAAP financial measures because it could not do so without unreasonable effort due to the unavailability of the information needed to calculate reconciling items and due to the variability, complexity and limited visibility of the adjusting items that would be excluded from the non-GAAP financial measures in future periods. When planning, forecasting and analyzing future periods, the Company does so primarily on a non-GAAP basis without preparing a GAAP analysis.
