FALLS CHURCH, Va., Aug. 05, 2021 (GLOBE NEWSWIRE) --  PAE Incorporated (“PAE” or the “Company”) (NASDAQ: PAE, PAEWW) today announced second-quarter 2021 financial and operating results.

CEO Commentary

PAE Interim President and CEO Charlie Peiffer said, “We delivered strong adjusted EBITDA and margins with solid revenue performance in the quarter. We started to see a pickup in contract awards activity, which provides the foundation for revenue growth heading into the second half of the year.”

Second-Quarter 2021 Results

Revenues for the quarter of $747.2 million increased $103.9 million, or 16.2%, compared to the prior year period. The increase was attributable to $93.1 million of revenue from recent acquisitions and by a $10.8 million net increase from new business awards and other changes in contract volume. The Global Mission Services and National Security Solutions segments’ revenues increased by approximately $3.5 million and $100.4 million, respectively.

Operating income for the quarter was $30.8 million, compared with operating income of $34.3 million in the prior year period. The decrease resulted from higher selling, general and administrative expenses and increased amortization of intangible assets, which decrease was partially offset by higher revenue volume.

The net income attributed to PAE for the quarter was $14.4 million, or $0.15 per diluted share, compared with a net loss of approximately $3.4 million, or $(0.04) per diluted share in the prior year period. The improvement in net income for the second quarter of 2021 was primarily driven by changes in fair value of the warrants, which increase was partially offset by the factors impacting operating income.
  
Adjusted EBITDA for the quarter was $53.3 million, or 7.1% of revenue, compared to $48.4 million, or 7.5% of revenue, in the prior year period. Adjusted EBITDA increased due to higher revenue volume while margins declined due primarily to higher selling, general and administrative expenses in the current period.

Global Mission Services
GMS revenues for the quarter of $511.3 million increased $3.5 million, or about 1.0%, compared to the prior year period. The increase was attributable to new business awards, which increase was partially offset by reductions in contract volume on certain programs.

GMS operating income for the quarter was $28.7 million, compared to $31.5 million in the prior-year period. The decrease was driven by higher selling, general and administrative expenses which was partially offset by higher revenue volume.

GMS adjusted operating income2 for the quarter was $34.6 million, or 6.8% of revenue, compared to $37.4 million, or an operating margin of 7.4% of revenue, in the prior year period. The reduction in GMS adjusted operating income and margins2 was driven by higher selling, general and administrative expenses, which decrease was partially offset by higher revenue volume.

National Security Solutions
NSS revenues for the quarter of $235.9 million increased $100.4 million, or 74.1%, compared to the prior year period. The increase was attributable to $93.1 million of revenue from recent acquisitions and a $7.4 million increase from in contract volume.

NSS operating income for the quarter was $9.2 million, compared to $7.7 million in the prior year period. The increase resulted from higher revenue volume and improved program performance, which increase was partially offset by higher selling, general and administrative expenses.

NSS adjusted operating income3 for the quarter was $18.7 million, or 7.9% of revenue, compared to $11.0 million, or 8.1% of revenue, in the prior year period. The variances in NSS adjusted operating income and margins3 were driven by the increase in revenue volume and program performance, which increases were partially offset by higher selling, general and administrative expenses.  

Cash Flow Summary

Net cash used in operating activities for the quarter of $11.9 million decreased $56.5 million over the prior year period, primarily as a result of lower comparable cash collections due to timing of customer payments, partially offset by customer advances and billings in excess of costs and net income growth.

As of June 27, 2021, PAE had cash and cash equivalents totaling $94.7 million and had no outstanding borrowings on its senior secured revolving credit facility.

Business Development Highlights and Contract Awards

Net bookings totaled $731 million in the second quarter and $2.9 billion over the trailing 12 months, representing a book to bill ratio of 1.0x for both the second quarter and trailing 12 months.

Notable second quarter awards received include:

Notable New Business Awards:

  • DIA SIA 3 task order: Edge Analytic Solutions, LLC, a joint venture between NSS and Prescient Edge Corporation, was awarded a task order, of which, approximately $65 million is attributable to NSS, to provide counter and human intelligence support services to a national security customer.
  • Contract Field Teams’ Maintenance Service Contract: GMS was awarded an approximate $30 million task order on the Contract Field Teams’ Maintenance Services Contract for aviation maintenance and logistics, which supports the U.S. Army’s 1106th Theater Aviation Sustainment Maintenance Group in Fresno, California.

Notable Recompete Awards:

  • Naval Expeditionary Forensics and Biometrics: NSS was awarded a contract, valued at approximately $95 million, to provide support to U.S. Navy efforts related to forensics and biometrics requirements.

Notable IDIQ Awards:

  • Naval Facilities Engineering Systems Command Far East: GMS was awarded a single award, indefinite delivery, indefinite quantity contract valued at approximately $74 million by Naval Facilities Engineering Systems Command Far East for base operating support services at Marine Corps Air Station Iwakuni, Japan.
  • U.S. Air Force Engineering Assessment, Procurement, Integration and Contractor Logistics Support: GMS won a seat on the 10-year, $950 million Engineering Assessment, Procurement, Integration and Contractor Logistics Support contract to support foreign military sales transactions focused on engineering, sustainment and integration-based solutions for intelligence, surveillance and reconnaissance platforms.

The Company’s backlog at the end of the quarter was $7.4 billion, of which approximately $1.2 billion was funded.

Following the end of the second quarter, GMS was awarded an approximately $402 million contract by the National Aeronautics and Space Administration to provide a wide range of facility support services at Lyndon B. Johnson Space Center in Houston, Texas. This award was subsequently protested by a competitor, and the protest is currently pending at the Government Accountability Office.

2021 Financial Outlook

PAE is reiterating the fiscal 2021 guidance it issued on March 11, 2021, based on the Company's financial results for the first six months of 2021 and its current outlook for the remainder of the year. The table below summarizes the Company's 2021 financial guidance:

Revenue: $3,050 million - $3,150 million
Adjusted EBITDA:      $205 million - $215 million
Cash flow provided by operations:  At least $120 million

Adjusted EBITDA is a non-GAAP financial measure. The Company is not providing a quantitative reconciliation of adjusted EBITDA in its 2021 financial guidance in reliance on the “unreasonable efforts” exception for forward-looking non-GAAP measures set forth in Securities and Exchange Commission rules because certain financial information, the probable significance of which cannot be determined, is not available and cannot be reasonably estimated without unreasonable effort and expense. In this regard, the Company does not provide a reconciliation of forward-looking adjusted EBITDA (non-GAAP) to GAAP net income, due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation. Because certain deductions for non-GAAP exclusions used to calculate projected net income may vary significantly based on actual events, the Company is not able to forecast on a GAAP basis with reasonable certainty all deductions needed to provide a GAAP calculation of projected net income at this time. The amounts of these deductions may be material and, therefore, could result in actual GAAP net income being materially less than is indicated by estimated adjusted EBITDA (non-GAAP). Due to the uncertainty of estimates and assumptions used in preparing forward-looking non-GAAP measures, actual results could differ materially from these non-GAAP financial projections.

Conference Call Information

As previously announced, PAE will host a conference call and webcast today, August 5, 2021, at 8 a.m. ET. Management will review the Company's second-quarter 2021 financial results, followed by a question-and-answer session.

Backlog represents the estimated amount of future revenues to be recognized under negotiated contracts and task orders as work is performed and excludes contract awards which have been protested by competitors until the protest is resolved in our favor. PAE segregates backlog into two categories, funded backlog and unfunded backlog.

Funded backlog refers to the value on contracts for which funding is appropriated less revenues previously recognized on these contracts.

Unfunded backlog represents the estimated future revenues to be earned from negotiated contracts for which funding has not been appropriated or authorized, and unexercised priced contract options. Unfunded backlog does not include any estimate of future potential task orders expected to be awarded under indefinite delivery, indefinite quantity contracts, U.S. General Services Administration schedules or other master agreement contract vehicles.

Non-GAAP Financial Measures

The Company uses EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted operating income per segment and adjusted operating income margin per segment as supplemental non-GAAP measures of performance. PAE defines EBITDA as net income excluding (i) interest expense, (ii) provision for or benefit from income taxes and (iii) depreciation and amortization. Adjusted EBITDA and adjusted operating income per segment exclude certain amounts included in EBITDA as provided in the reconciliations provided herein. Adjusted EBITDA is equal to the sum of adjusted operating income for each segment. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by revenues expressed as a percentage and adjusted operating income margin is calculated as adjusted operating income divided by revenues expressed as a percentage.

For 2021 and 2020, the Company’s net income was impacted by certain events, as described in the footnotes to the reconciliation tables, that do not reflect the cost of our operations and which may affect the period-over-period assessment of operating results. The non-GAAP financial measures demonstrate the impact of these events.

These non-GAAP measures of performance are used by management to conduct and evaluate its business during its regular review of operating results for the periods presented. Management and the Company’s board utilize these non-GAAP measures to make decisions about the use of the Company’s resources, analyze performance between periods, develop internal projections and measure management performance. PAE believes these non-GAAP measures are useful to investors in evaluating the Company’s ongoing operating and financial results and understanding how such results compare with the Company’s historical performance.

In addition to the above non-GAAP financial measures, the Company has included backlog, net bookings, and book-to-bill ratio in this release. Backlog is an operational measure representing the estimated amount of future revenues to be recognized under negotiated contracts and task orders as work is performed and excludes contract awards which have been protested by competitors until the protest is resolved in our favor. Net bookings are an operational measure representing the change in backlog between reporting periods plus reported revenue for the period and book-to-bill ratio is an operational measure representing net bookings divided by reported revenues for the same period. We believe backlog, net bookings and book-to-bill ratio are useful metrics for investors because they are an important measure of business development performance and revenue growth. These metrics are used by management to conduct and evaluate its business during its regular review of operating results for the periods presented.
