Thomas E. Stiehle
Executive Vice President And Chief Financial Officer at Huntington Ingalls Industries
Thanks Chris and good morning. Today. I'll review our fourth quarter and full year results and also provide some additional color regarding our outlook for 2025. For more detail on the segment results, please refer to the earnings release issued this morning and posted to our website. Beginning with our consolidated fourth quarter results on Slide 6, our fourth quarter revenues of $3 billion decreased approximately 5% compared to the same period last year. This decline was driven by lower year over year revenue at all three segments. Ingall's revenues of $736 million decreased 64 million or 8% compared to the fourth quarter of 2023, driven primarily by lower volumes on amphibious assault ships, partially offset by higher surface combatant revenues at Newport News. Revenues of $1.6 billion declined 77 million or 4.6% from the fourth quarter of 2023, primarily due to lower RCOH volumes, unfavorable cumulative adjustments on the Virginia class and aircraft carrier construction programs partially offset by higher Columbia class volumes.
At Mission Technologies fourth quarter 2024 revenues of $713 million decreased 32 million or 4.3% from the fourth quarter of 2023, primarily driven by lower volumes in C5ISR due to non recurring product revenue in the fourth quarter of 2023. Moving to slide 7, segment operating income for the quarter was 103 million and segment operating margin was 3.4%. This compares to 330 million and 10.4% respectively in the fourth quarter of 2023. Fourth quarter 2023 results included two non recurring favorable items that make for a difficult year over year comparison. The first Item was a $70.5 million sale of a court judgment at Ingalls. The second was a $49.5 million insurance claim to settlement at Mission Technologies. Engil's operating income of $46 million and margin of 6.3% compares to 169 million and 21.1% respectively in the fourth quarter of 2023. The prior year period included both the favorable sale of a court judgment that I noted as well as a surface combatant related contract incentive.
Newport News Fourth quarter 2024 operating income of 38 million and margin of 2.4% compares to 110 million and 6.6% respectively in the fourth quarter of 2023. The declines were driven by lower performance on Virginia class submarine and new carrier construction partially offset by contract incentives on the Columbia class program. Shipbuilding margin for the fourth quarter of 2024 was 3.6%. Mission Technologies fourth quarter operating income of $19 million and segment operating margin of 2.7% compares to $51 million and 6.8% respectively in the fourth quarter of 2023. The declines were primarily driven by favorable insurance claim settlement that occurred in the fourth quarter of 2023. Net earnings in the quarter were 123 million compared to 274 million in the fourth quarter of last year. Diluted earnings per share in the quarter were $3.15 compared to $6.90 in the fourth quarter of the previous year.
Moving on to Consolidated Results for 2024 On Slide 8, revenues of $11.5 billion increased 81 million or approximately 1% compared to 2023. Growth was driven primarily by higher volumes at Mission Technologies, partially offset by lower volumes at Newport News Shipbuilding. Ingalls revenues of 2.8 billion in 2024 increased 15 million or 0.5% from 2023, driven primarily by higher volumes in surface combatants, largely offset by a lower amphibious assault ship and NSE program revenues.
At Newport News 2024 revenue of 6 billion decreased by 164 million or 2.7% from 2023, primarily due to unfavorable Virginia class cumulative adjustments as well as lower volumes in aircraft carriers and nuclear support services, partially offset by higher volume on the Columbia program. At Mission Technologies 2024, revenues of 2.9 billion increased 238 million or 8.8% from 2023, primarily driven by higher volumes in cyber, electronic warfare and space as well as C5ISR contracts. Moving to Slide 9, segment operating income for the year was 573 million and segment operating margin was 5%. This compares to 842 million and 7.4% respectively in 2023. Ingalls operating income of $211 million and margin of 7.6% in 2024 compares to $362 million and 13.2% respectively in 2023. The declines were primarily driven by the sale of the court judgment in 2023 as well as lower performance on amphibious assault ships and surface combatants. Newport News 2024 operating income 246 million and margin of 4.1% compared to 379 million and 6.2% respectively in 2023.
The decreases were primarily driven by lower Virginia class and aircraft carrier performance, partially offset by Columbia class contract incentives. Shipbuilding margin for 2024 was 5.2% within the revised guidance range we provided for the year. Net cumulative adjustments for the year were negative 126 million. Newport News net cumulative adjustment was negative 154 million, partially offset by positive net cumulative adjustments at both Ingalls and mission technologies of approximately 14 million. Mission technologies 2024 operating income of 116 million and segment operating margin of 3.9% both improved from 101 million and 3.7% respectively in 2023. The improvement was driven primarily by volume and performance in cyber, electronic warfare and space contracts, stronger performance in fleet sustainment as well as higher equity income.
Again, The Mission Technologies 2023 results included a favorable $49.5 million insurance claim, so we are lapping that difficult comparison and we believe our results still show strong absolute income growth and margin expansion. Mission Technologies 2024 results included approximately 99 million of amortization to purchase intangible assets compared to approximately 109 million in 2023. Mission Technologies EBITDA margin for 2024 was 7.9%. Company net earnings in 2024 were $550 million compared to $681 million in 2023. Diluted earnings per share in 2024 were $13.96 compared to $17.07 in 2023. Turning to cash and capital deployment on slide 102024 free cash flow was 40 million, consistent with our most recent guidance and reflecting factors previously discussed. During the year, the company invested $353 million in capital expenditures or 3.1% of sales.
As we continue to prioritize higher throughput in our shipyards, we paid $206 million in dividends while ending 2024 with $831 million in cash and cash equivalents on hand and liquidity of approximately 2.5 billion. Cash contributions to our pension and other post retirement benefit plans totaled 47 million in 2024. Our pension outlook for 2025 has modestly improved from the update that we provided in November giving this increase in discount rates partially offset by 2024 asset returns that was slightly below our expectations. Actual Asset returns for 2020 forward 7.7%. Our five year pension outlook has been updated and is available in the appendix of today's presentation on slide 13.
Turning to slide 11 and our financial outlook first, we are reaffirming our medium to long term growth targets for both shipbuilding and Mission Technologies. As Chris noted, we see a clear path to 15 billion in annual revenue by the end of the decade given our robust backlog and very strong demand across the portfolio. Regarding 2025 expectations, Chris provided our operational guidance, but let me provide a bit more color on our cash flow outlook. We expect 2025 free cash flow of between 300 and 500 million. Performance on contracts entered into prior to the commencement of the COVID pandemic has impacted our ability to achieve program milestones and corresponding cash receipts. We expect this headwind will continue in 2025, which along with elevated capital expenditures and cash taxes is impacting our overall cash generation. We expect 2025 capital expenditures to be approximately 4% of sales as we continue to thoughtfully invest in increasing our shipbuilding efficiency and throughput. Additionally, we expect our 2025 cash taxes will total approximately 220 million. Regarding our expectations for the first quarter in 2025, we expect approximately $2.1 billion for shipbuilding revenues and $680 million of mission technologies revenues.
With shipbuilding margin near 5.5% and Mission Technologies operating margin approximately 3% Consistent with normal cash flow cadence, we expect first quarter free cash flow to be negative, representing a use of between 300 and 500 million and working as working capital continues to build through mid year before we are able to reach program milestones in contract awards. Turning for a moment to capital allocation, as we have highlighted today, we will continue to invest in our business to maintain and grow the capacity of our shipyards. Our approach to dividends and returning excess cash to shareholders remains unchanged. Our focus now, of course, is working through challenged contracts and returning free cash flow to more normalized levels.
To close my remarks, achieving the throughput cost reduction and contract award initiatives that we have outlined are critical to stabilizing shipbuilding performance in 2025 and achieving the outlook we have provided. Similar to 2024, we expect that about 70% of the shipbuilding revenue generated in 2025 will be derived from pre Covid contracts. We forecast approximately 60% of 2026 shipbuilding revenue will be derived from pre Covid contracts. Finally, we expect that in 2027, a majority of the shipbuilding revenue will be derived from contracts that reflect the current operating environment and we will set the foundation for margin improvement and returns towards historical margin levels.
With that, I'll turn the call back over to Kristi for Q and A.
