MANAGEMENT COMMENTARY

“The second phase of our business transformation strategy has been focused on the pursuit of stable, profitable growth, so we were pleased by our first quarter results which were highlighted by steady growth in our Services division and small-scale fabrication business,” said Richard Heo, Gulf Island’s President and Chief Executive Officer. “Our Services division experienced improved margins, leading to a year-over-year increase in operating income of almost 100%. Overall activity in our core Gulf Coast region remains robust, and we still expect growth in our Services Division and small-scale fabrication business during 2023.”

“While we are disappointed that we have not gained more clarity on our large fabrication project, which remains suspended, we remain encouraged by the favorable trends in the large fabrication business and are pursuing several new project opportunities, which we hope will be awarded in the second half of 2023,” continued Heo. “We will continue to look for opportunities to minimize the financial impact of the large fabrication project suspension as we pursue other large fabrication awards to replace the contract in the event the project is permanently suspended.”

“We remain encouraged by the stability of our Services division, with first quarter operating margins of 10.8%, an increase of over 500 basis points from the prior year,” stated Westley Stockton, Gulf Island’s Chief Financial Officer. “We ended the quarter with nearly $45 million in cash, which was consistent with year-end levels, and we remain confident that we have adequate liquidity and financial flexibility to fund growth opportunities in both our Services and Fabrication businesses.”

“With the wind down of our Shipyard operations nearing completion, we soon expect to be able to focus all of our resources and attention on our Services and Fabrication businesses,” noted Heo. “We are excited by the strong bidding activity in our markets, in particular the opportunities in our large fabrication business, and look forward to continuing to execute on our strategic initiatives,” concluded Heo.

STRATEGIC UPDATE

Gulf Island continues to execute on the second phase of its strategic transformation, which is focused on generating stable, profitable growth based on pursuing new growth end markets, growing and diversifying its services business, further strengthening project execution, and expanding its skilled labor workforce, while continuing to pursue opportunities in its traditional offshore markets. Below is an update on the progress made on each of these initiatives during the first quarter 2023:

Pursue traditional offshore markets – Gulf Island continues to fabricate structures associated with its traditional offshore markets, including subsea and offshore structures. Bidding activity in the Gulf of Mexico remains active as evidenced by continued new awards momentum during the first quarter 2023.

Pursue new growth end markets – Gulf Island has a strong foundation to pursue new growth opportunities in its core Gulf Coast region, primarily in the LNG, petrochemical, and energy transition markets, and bidding activity on large project opportunities remains active, driven by the strong industry fundamentals combined with limited industry capacity. Gulf Island was recently awarded a small fabrication contract in support of an aerospace project, and the Company is in discussions with several customers regarding additional fabrication opportunities.

Grow and diversify services business – Gulf Island continues to expand its Services business with first quarter revenues growing 4.5% compared to the first quarter 2022. Gulf Island remains encouraged by the positive customer reception to its new Spark Safety services line, which provides welding enclosures that create a safe environment for hot work to be carried out without the need to shut down operations. The Company commenced its second Spark Safety project in the first quarter and expects the business line to be a material contributor to growth in 2023.

Further strengthen project execution and maintain bidding discipline – Project execution remained strong in the first quarter with projects performing consistent with as-sold estimates. Gulf Island will continue to take a disciplined approach when bidding on large fabrication project opportunities, especially given the challenges with availability of skilled labor, while looking for ways to minimize the impact of the suspension of its large fabrication project.

Expand skilled workforce – Gulf Island made significant progress expanding its skilled services labor force through its acquisition of a complimentary services and industrial staffing business in late 2021, and the Services Division has successfully maintained its headcount levels despite the competitive industry-wide labor environment.

SEGMENT RESULTS FOR FIRST QUARTER 2023

Services Segment – Revenue for the first quarter 2023 was $21.6 million, an increase of 4.5% compared to the first quarter 2022. The increase was primarily due to incremental revenue associated with the division’s new welding enclosures business line (commenced in the third quarter 2022).

New project awards were $21.5 million for the first quarter 2023, representing a 10.7% year-over-year increase, and backlog totaled $1.2 million at March 31, 2023. The new award growth was driven by the welding enclosures business line. See “Non-GAAP Measures” below for the Company’s definition of new project awards and backlog.

Operating income was $2.3 million for the first quarter 2023, compared to $1.2 million for the first quarter 2022. EBITDA for the first quarter was $2.8 million (or 12.9% of revenue), versus $1.5 million (or 7.5% of revenue) for the prior year period. Operating results for the first quarter 2023 benefited from strong trends in the division’s legacy offshore services business and a more favorable project margin mix, including the benefit of the division’s welding enclosures business line. See “Non-GAAP Measures” below for the Company’s definition of EBITDA and a reconciliation of the Services Division operating income to EBITDA.

Fabrication Segment – Revenue for the first quarter 2023 was $39.7 million, an increase of $34.0 million compared to the first quarter 2022. The increase was due to higher small-scale fabrication activity and contribution from the division’s large fabrication project prior to its suspension (discussed below). A significant portion of the revenue recognized on the large fabrication project was related to procurement activities.

New project awards were $16.7 million for the first quarter 2023, representing a 101.4% year-over-year increase, and backlog totaled $87.3 million (inclusive of $75.9 million related to the division’s suspended large fabrication project) at March 31, 2023. The new award growth was driven by higher small-scale fabrication work. In February 2023, the Company received direction from its customer to suspend all activities on the division’s large fabrication project for offshore structures. No duration of the suspension or potential timing of recommencement of the project was provided. See “Non-GAAP Measures” below for the Company’s definition of new project awards and backlog.

Operating income was $2.2 million for the first quarter 2023, compared to an operating loss of $2.9 million for the first quarter 2022. EBITDA for the first quarter 2023 was $3.1 million, versus a loss of $2.1 million for the prior year period. The improved profitability in 2023 was the result of higher revenue and a decrease in the under-recovery of overhead costs due to improved utilization of facilities and resources and recoveries associated with the division’s large fabrication project prior to its suspension, offset partially by a lower margin mix relative to 2022 associated with small-scale fabrication work. See “Non-GAAP Measures” below for the Company’s definition of EBITDA and a reconciliation of the Fabrication Division operating income and loss to EBITDA.

Shipyard Segment – Revenue for the first quarter 2023 was $1.3 million, a decrease of $1.2 million compared to the first quarter 2022. Revenue for both quarters related entirely to the division’s seventy-vehicle ferry and forty-vehicle ferry projects.

Operating loss was $2.2 million for the first quarter 2023, compared to an operating loss of $1.2 million for the first quarter 2022. Operating results for the first quarter 2023 and 2022 included vessel holding costs and legal and advisory fees of $1.7 million and $0.9 million, respectively, associated with the Company’s MPSV Litigation (defined below).

Corporate Segment – Operating loss was $2.1 million for the first quarter 2023, compared to an operating loss of $2.0 million for the first quarter 2022.

Segment Descriptions – The Company’s divisions represent its reportable segments which are “Services”, “Fabrication”, “Shipyard” and “Corporate”. The Services Segment includes offshore and onshore services work performed at customer facilities, including offshore platforms. The Fabrication Segment includes all fabrication work performed on-site at the Company’s facilities, including pull-through fabrication work for the Services Segment. The Shipyard Segment includes two ferries under construction that are anticipated to be completed by the second quarter 2023 and holding costs and legal fees associated with the Company’s contract dispute for two multi-purpose supply vessels (“MPSV Litigation”). The Corporate Segment includes costs that are not directly related to the Company’s operating segments, including the costs of being a publicly traded company.

BALANCE SHEET AND LIQUIDITY

The Company’s cash and short-term investments balance at March 31, 2023 was $44.7 million, including $1.2 million of restricted cash associated with outstanding letters of credit. At March 31, 2023, the Company had no bank debt.

NON-GAAP MEASURES

This Release includes certain non-GAAP measures, including earnings before interest, taxes, depreciation and amortization (“EBITDA”), new project awards and backlog. The Company believes EBITDA is a useful supplemental measure as it reflects the Company's operating results excluding the non-cash impacts of depreciation and amortization. Reconciliations of the relevant EBITDA amount to the most comparable GAAP measure are presented under “Consolidated Results of Operations” and “Results of Operations by Segment” below.

The Company believes new project awards and backlog are useful supplemental measures as they represent work that the Company is obligated to perform under its current contracts. New project awards represent the expected revenue value of contract commitments received during a given period, including scope growth on existing contract commitments. Backlog represents the unrecognized revenue value of new project awards, and at March 31, 2023, was consistent with the value of remaining performance obligations for contracts as determined under GAAP.

Non-GAAP measures are not intended to be replacements or alternatives to GAAP measures, and investors are urged to consider these non-GAAP measures in addition to, and not in substitution for, measures prepared in accordance with GAAP. The Company may present or calculate non-GAAP measures differently from other companies.
