Karen Sedgwick
Executive Vice President and Chief Financial Officer at Sempra
Thank you, Justin. I'm excited to share our year end results and give you more details on our financial plan. Earlier today, Sempra reported fourth quarter 2023 GAAP earnings of $737 million or $1.16 per share. This compares to fourth quarter 2022 GAAP earnings of $438 million or $0.69 per share. On an adjusted basis, fourth quarter 2023 earnings were $719 million or $1.13 per share. This compares to our fourth quarter 2022 earnings of $743 million or $1.17 per share. Full year 2023 GAAP earnings were $3,030 million or $4.79 per share. This compares to 2022 GAAP earnings of $2,094 million or $3.31 per share. On an adjusted basis, full year 2023 earnings were $2,920 million or $4.61 per share. This compares to our previous full year 2022 adjusted earnings of $2,915 million or $4.61 per share. This year's results demonstrate the combined strength of our three growth platforms and sets us up for improved growth in 2024. Please turn to the next slide.
Now I will summarize the variance of full year 2023 adjusted earnings compared to the same period for last year. At Sempra California, we had $69 million of higher net interest expense, partially offset by net tax benefits, offset by $51 million of higher electric transmission and CPUC based operating margin and $52 million of higher regulatory interest income and regulatory awards. At Sempra Texas, we had $2 million of higher equity earnings attributable to increased invested capital, partially offset by higher interest and operating expenses. I'd note that earnings in 2022 and 2023 were impacted by the lack of capital trackers that can't be filed during a rate case.
At Sempra Infrastructure, we had $85 million of higher earnings attributable to non-controlling interests. $10 million of higher taxes partially offset by lower interest expense given increased capitalized interest, offset by $49 million of higher transportation tariffs, higher asset supply optimization, partially offset by lower equity earnings from Cameron LNG. For Port Arthur, while our ownership stake is approximately 20%, we consolidate the project for accounting purposes, thus capitalizing interest based on the project's in progress construction. As construction advances, you're seeing the impact of higher capitalized interest versus previous years. Ultimately, these capitalized costs will be amortized back as higher depreciation after the plant moves into commercial operations.
At Sempra Parent, there were $15 million of higher investment gains, partially offset by higher net interest expense and lower income tax benefits. Please turn to the next slide. Turning to new investments, as Jeff noted earlier, we're announcing a company record $48 billion capital plan, with over 90% of the planned investment allocated to our regulated utilities. This represents an impressive 20% increase over the previous plan and will ultimately serve as the foundation for our company's growth over the coming years. About $24.1 billion or roughly half of the capital plan is marked for investment at Sempra California's two utilities, which together have a weighted average ROE of approximately 10.5%.
At Sempra Texas, $19.5 billion includes our proportionate share of Oncor's planned capex, where recent legislative development should help Oncor reduce regulatory lag and improve its ability to help lessen the gap between the authorized and actual rates of return. The remaining $4.4 billion are primarily associated with Sempra Infrastructure's LNG projects under construction and their associated infrastructure. Please turn to the next slide.
With this record capital plan, I would like to illustrate some of the key sources and uses. As you know, Sempra raised equity in November 2023 to support our future investment needs and mitigate the financing risk associated with the capital plan. As a result, we are in a strong financial position and anticipate our reliable internal operating cash flows and regulatory authorized debt will provide the vast majority of our financing needs. We are a growing business, while maintaining balance sheet strength, all with the goal of delivering attractive total shareholder returns over the long term. Along those lines, Sempra will continue to target a 50% to 60% dividend payout ratio, providing plenty of reinvestment flexibility. Please turn to the next slide.
Moving to the utilities, our strong earnings trajectory is underpinned by long-term rate base growth. California and Texas rate base is expected to grow with 7% and 11% respectively from 2023 to 2028. Our rate base is split approximately evenly between California and Texas, where we benefit from constructive regulatory jurisdictions and strong macroeconomic growth. On a combined basis, we anticipate just over 9% annual growth through 2028 and this gives us added confidence in achieving our projected 6% to 8% long term EPS growth rate. Please turn to the next slide.
Given the strength of our 2023 results, we've narrowed our 2024 earnings guidance estimates and are now projecting EPS guidance for the year ranging from $4.60 to $4.90. Also we're announcing 2025 earnings per share guidance with a range of $4.90 to $5.25. This equates to a projected EPS bidpoint that's about 7% higher than 2024 guidance. Now let's break down a few of the assumptions embedded in these figures. At Sempra California, this already includes the cost of capital trigger. As for the GRC, we're assuming outcomes that are in the range of historical rate case decisions and continue to work constructively with the CPUC and interveners through the proceeding to achieve an outcome that allows us to continue to deliver safe, reliable and sustainable energy for our customers.
Turning to Texas, we said in the prior call the guidance took into effect Oncor's second DCRF. Subject to PUCT approval, the system resiliency plan will apply to 2025 through 2027 and due to timing differences between filing and construction of projects, we would expect minimal financial impact in 2025. At Sempra Infrastructure, there are a few things to highlight.
2022 and 2023 benefited from an attractive commodity price environment and in 2023 we've received the cumulative benefit of new tariffs on select Mexico pipelines. Due to the conservative nature of our project development process, we secured rights on the gas pipeline connecting ECA well in advance of COD. This allowed us to better optimize results during this period, but we would expect this impact to moderate as we go forward, particularly with a lower forward curve for natural gas.
And now with the magnitude of large projects currently under construction, we have better visibility into certain non-capitalized costs that have now been added to our 2024 plan. And we have ECA LNG Phase 1, expected to come online in the summer of 2025, with full year operations expected in 2026. And finally, regarding the share count, the main driver of the increase is our recent equity offering. As we've discussed, the green shoe of just over 2 million shares settled immediately in November of 2023. Over the course of this year, we're assuming weighted average diluted shares will increase by 4 million, which reflects the dividend reinvestment program, equity based plans and the drawdown of our forward settlement, which we now assume will occur in the second half of 2024. Thus, 2025 reflects those shares outstanding for the entire year, increasing our share count to approximately 654 million shares. Please turn to the next slide.
In addition to our new five year plan, we've added this slide in an effort to be more responsive to input from our many investors. Here, it shows the various categories of investments that we're tracking or developing that fall outside of our current plan. It totals over $10 billion and many of these opportunities could form part of our future capital campaign. Please turn to the next slide.
You've heard this from our other executives today, but it is important to note that we're excited by the investment opportunities in front of us. We are owners and operators of top tier T&D utility platforms located in North America's largest economies. Moreover, our utilities benefit from constructive regulation that support significant investment and help ensure safe, reliable, resilient and increasingly sustainable energy for our customers.
Over time, our key priorities remain largely the same. We will invest in our high quality T&D energy infrastructure to improve customer service, maintain a prudent balance sheet and provide compelling returns to shareholders. A record $48 billion capital plan focused on our regulated utilities will be the primary foundation for increasing rate base, growth and earnings power and gives us confidence in achieving our projected long term EPS growth rate of 6% to 8%.
We thank you for joining us as we continue to build North America's premier energy infrastructure company and we're as enthusiastic as ever about our opportunity to continue delivering attractive, risk adjusted returns. I've had the opportunity to meet with many of you over the last month and I'll be out on the road with the IR team in March and hope to connect with those of you I haven't had a chance to meet yet.
With that, I'd now like to open the call for some of your questions.
