HII Huntington Ingalls Industries Inc

HII (NYSE: HII) today reported results for the third quarter of fiscal 2024 and provided an update on its outlook.

Highlights

• Third quarter revenues were $2.7 billion
• Third quarter net earnings were $101 million or $2.56 diluted earnings per share
• Third quarter free cash flow1 was $136 million
• Company is providing updated fiscal 2024 outlook
• Company is withdrawing 5-year free cash flow1 outlook

Third Quarter Results

Third quarter 2024 revenues of $2.7 billion were down 2.4% from the third quarter of 2023, driven by lower volume at Ingalls Shipbuilding and Newport News Shipbuilding, partially offset by growth at Mission Technologies.

Operating income in the third quarter of 2024 was $82 million and operating margin was 3.0%, compared to $172 million and 6.1%, respectively, in the third quarter of 2023. The decreases were primarily driven by lower segment operating income1 compared to the prior year.

Segment operating income1 in the third quarter of 2024 was $97 million and segment operating margin1 was 3.5%, compared to $187 million and 6.6%, respectively, in the third quarter of 2023. The decreases were driven primarily by performance at Newport News Shipbuilding, which included a net unfavorable cumulative adjustment of $78 million, as well as lower performance at Ingalls Shipbuilding.

Net earnings in the quarter were $101 million, compared to $148 million in the third quarter of 2023. Diluted earnings per share in the quarter was $2.56, compared to $3.70 in the third quarter of 2023.

Net cash provided by operating activities in the quarter was $213 million and free cash flow1 was $136 million, compared to net cash provided by operating activities of $335 million and free cash flow1 of $293 million in the third quarter of 2023.

New contract awards in the third quarter of 2024 were $3.6 billion, bringing total backlog to approximately $49.4 billion as of September 30, 2024. Awards in the third quarter of 2024 included approximately $565 million related to the multi-ship amphibious award at Ingalls Shipbuilding.

Commentary on Third Quarter Results

"Two issues have impacted our results and guidance for the year," said Chris Kastner, HII’s president and CEO.

"First, based on constructive discussions with our Navy partner, we expected to reach an agreement for Virginia-class Block V and Block VI and Columbia-class submarines in the second half of 2024.

"Starting this fall, some uncertainty emerged about the timing of that agreement. While we are confident an agreement will be reached and discussions continue, we have updated our profitability and cash flow assumptions based on the uncertain timing and structure of the award.

"We continue to pursue innovative contracting approaches that incentivize greater investments in our workforce, facilities and technology. These investments are critical to yield accelerated program schedules that meet the urgent needs of the Navy.

"Second, our assumptions of performance improvement and risk reduction have not been achieved, due to late critical material deliveries from the supply chain and reduced experience levels within our teams, both in production touch labor and supervision. This leads to labor inefficiency, and in some cases to rework, which can affect program schedules.

"It bears repeating that nearly all of the ships currently under construction were negotiated prior to COVID, and since those contracts were signed we have seen a significant loss of shipbuilding experience in our yards. Those ship contracts, which we are still operating under at Newport News, did not anticipate in their cost targets and risk limiting clauses the significant disruption of our workforce and supply chain, or extended periods of heightened cost inflation.

"Let me be clear: delays and cost increases on these ships are unacceptable to me, my team, and all of us at HII. Looking ahead, we continue to take decisive actions to focus on the fundamentals of shipbuilding to ensure that we finish these ships, get them delivered to the Navy, and transition to ships negotiated in the context of our current economic reality.

"To summarize, we remain focused on optimizing our operations, improving our cost structure and shipbuilding performance, and driving higher throughput. We firmly believe the actions we are taking will enable us to stabilize performance as we continue to work through these ship contracts."

Exhibit B: Non-GAAP Measures Definitions & Reconciliations

We make reference to “segment operating income,” “segment operating margin,” “shipbuilding revenue,” “shipbuilding operating margin,” "Mission Technologies EBITDA," “Mission Technologies EBITDA margin” and “free cash flow.”

We internally manage our operations by reference to segment operating income and segment operating margin, which are not recognized measures under GAAP. When analyzing our operating performance, investors should use segment operating income and segment operating margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. They are measures that we use to evaluate our core operating performance. We believe that segment operating income and segment operating margin reflect additional ways of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income and segment operating margin may not be comparable to similarly titled measures of other companies.

Shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin are not measures recognized under GAAP. They are measures that we use to evaluate our core operating performance. When analyzing our operating performance, investors should use shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP. We believe that shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. We believe these measures are used by investors and are a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of shipbuilding revenue, shipbuilding operating margin, Mission Technologies EBITDA and Mission Technologies EBITDA margin may not be comparable to similarly titled measures of other companies.

Free cash flow is not a measure recognized under GAAP. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for net earnings as a measure of our performance or net cash provided or used by operating activities as a measure of our liquidity. We believe free cash flow is an important measure for our investors because it provides them insight into our current and period-to-period performance and our ability to generate cash from continuing operations. We also use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. Free cash flow may not be comparable to similarly titled measures of other companies.

In reliance upon Item 10(e)(1)(i)(B) of Regulation S-K, reconciliations of forward-looking GAAP and non-GAAP measures are not provided because of the unreasonable effort associated with providing such reconciliations due to the variability in the occurrence and the amounts of certain components of GAAP and non-GAAP measures. For the same reasons, we are unable to address the significance of the unavailable information, which could be material to future results.

Segment operating income is defined as operating income for the relevant segment(s) before the Operating FAS/CAS Adjustment and non-current state income taxes.

Segment operating margin is defined as segment operating income as a percentage of sales and service revenues.

Shipbuilding revenue is defined as the combined sales and service revenues from our Newport News Shipbuilding segment and Ingalls Shipbuilding segment.

Shipbuilding operating margin is defined as the combined segment operating income of our Newport News Shipbuilding segment and Ingalls Shipbuilding segment as a percentage of shipbuilding revenue.

Mission Technologies EBITDA is defined as Mission Technologies segment operating income before interest expense, income taxes, depreciation, and amortization.

Mission Technologies EBITDA margin is defined as Mission Technologies EBITDA as a percentage of Mission Technologies revenues.

Free cash flow is defined as net cash provided by (used in) operating activities less capital expenditures net of related grant proceeds.

Operating FAS/CAS Adjustment is defined as the difference between the service cost component of our pension and other postretirement expense determined in accordance with GAAP (FAS) and our pension and other postretirement expense under U.S. Cost Accounting Standards (CAS).

Non-current state income taxes are defined as deferred state income taxes, which reflect the change in deferred state tax assets and liabilities and the tax expense or benefit associated with changes in state uncertain tax positions in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Certain of the financial measures we present are adjusted for the Operating FAS/CAS Adjustment and non-current state income taxes to reflect the company’s performance based upon the pension costs and state tax expense charged to our contracts under CAS. We use these adjusted measures as internal measures of operating performance and for performance-based compensation decisions.
