Thank you, operator. This is Ted Durbin, Head of Investor Relations of STEM. Welcome to our fourth quarter and full year 2023 earnings call. Before we begin, please note that some of the statements we will be making today are forward-looking. These matters involve risks and uncertainties that could cause our results to differ materially from those projected in these statements. We, therefore, refer you to our latest 10-K and other SEC filings. Our comments today also include non-GAAP financial measures. Additional details and reconciliations to the most directly comparable GAAP financial measures can be found in our earnings press release. We will be using a slide presentation today to discuss our results. Our earnings press release and presentation are on the Investor Relations section of our website at www.stem.com. John Carrington, our CEO; and Bill Bush, CFO, will start the call today with prepared remarks. Mike Carlson, COO; and Prakesh Patel, Chief Strategy Officer, will also be available for the question-and-answer portion of the call. And now, I will turn the call over to John.

Thank you, Ted. Good afternoon, everyone and thank you for joining us today. Beginning with Slide 3, our agenda today will cover fourth quarter and full-year highlights, outline our 2024 guiding principles and provide several business updates. Bill will then discuss our financial results and introduce our 2024 guidance. Please turn to Slide 4 on our fourth quarter and full year 2023 results and highlights. Starting on the left side of the page, we recognized $4.6 million of adjusted EBITDA. This is our first quarter of positive adjusted EBITDA in company history and meets a critical milestone goal we set for ourselves in 2022. We accomplished our goal through revenue and gross margin growth and ongoing operating expense discipline. For the quarter, our GAAP gross margin was 7% and non-GAAP gross margin was 13%. For the year, GAAP gross margin was 1% and non-GAAP gross margin was 15%, which is in line with our guidance. We also continue to grow our high-margin recurring revenue with CARR up 39% year-over-year and in line with the guidance range that was increased by 9% at the midpoint in November. Fourth quarter bookings brought us to just over $1.5 billion for the year, again, in line with guidance. Lastly, our operating cash flow improved significantly in the second half of 2023, up $35 million in the fourth quarter of 2023 versus fourth-quarter 2022 based on improved profitability and better working capital management. This is a metric we will highlight throughout 2024. Moving to the Q4 highlights on the right side of this slide. Our commercial momentum has continued, having signed approximately 800 megawatt hours of software-only contracts since the start of the year. That is a nearly 15% increase in our contracted storage AUM in just the first 2 months of 2024. Today, we announced a contract with Mercuria Energy Trading, our first PowerBidder Pro win and we continue to receive numerous accolades for our leading software platform, Athena. Our customers continue to recognize and value our differentiated offerings, as indicated by our high retention rates and top Net Promoter Scores. In December, we published a white paper that demonstrated through backcasting simulation that STEM outperformed competitive software offerings by 28% on average. Customers choose their energy storage partner based on this performance and we are excited to further evidence our superior software offering. Importantly, we expect to generate at least $50 million of operating cash flow in 2024. I'll leave the details on guidance to Bill but this positive cash flow and measured investments is a key reason why we expect to grow our cash balance this year and are confident we will not need to issue equity to fund operations going forward. Now, let's turn to Slide 5 to discuss our 3 guiding principles for the year ahead. First, cash flow generation. In 2024 and beyond, we expect to generate positive growing free cash flow. We will achieve this by meeting our revenue and margin targets with continued discipline on our operating expenses and reducing our working capital intensity. And again, we do not expect to issue equity to meet our plan. We believe building a business that can fund operating expenses from free cash flow is a critical goal in the maturation of our company and differentiates our business strategy and market opportunity across the sector. Second, build software services revenue. Later, we will talk about our momentum on software-only wins but we are also focused on converting our contracted software revenue into annual recurring revenue. As Bill will detail later, we have a significant amount of gross profit potential as these systems come online. We have also retooled some of our leadership team with a sole focus on professional services and software-only opportunities. Professional services drive high-margin revenue earlier in the installation process and is a service customers want STEM to provide. Achieving our growth targets for software services is a strategic imperative across the organization and we expect to provide midyear updates on our progress. Third, we will extend our technology leadership position. We plan to continue innovating Athena through the acceleration of software product launches into markets where we have a differentiated advantage such as public power entities. Generative AI and our India Center of Excellence are both enabling accelerated software development productivity. This global development platform delivers daily releases of software code at high velocity for our customers and enables new products for market expansion. We executed on most of our key commitments in 2023 and are confident in our 2024 plan. We are proud of achieving positive adjusted EBITDA in the second half of 2023 and hitting our gross margin, bookings and CARR targets. In addition, through disciplined management of operating expenses, we are on track to reach our cash OpEx target in 2024, 1 year earlier than our 2022 Analyst Day forecast. In fact, last year, we decreased our average wage expense by 31% while nearly doubling our contracted backlog year-over-year. Let's turn to Slide 6 on our commercial traction. Stem’s leading software solutions continue to resonate with a range of customers. As previously mentioned, we have signed approximately 800 megawatt hours of software-only storage contracts in ERCOT and CAISO, 2 of the fastest-growing regions for energy storage. We see this momentum as validation of our differentiated software strategy as Athena consistently delivers significant outperformance relative to competitors. We've seen multiple proof points of consistent customer satisfaction, retention rates are at all-time highs with solar at 99.2% and storage at 98.5%. Additionally, we are proud to announce consistently great Net Promoter Scores of 68 for storage and 62 for solar. These scores represent above-average likelihood of customers willing to recommend Stem. Please turn to Slide 7. In September, we introduced PowerBidder Pro, a full-featured energy trading toolkit for asset owners and traders. Today, we are announcing that Mercuria will be our first PowerBidder Pro customer. This software-only agreement will support bid optimization for their first ERCOT energy storage systems. Mercuria will have access to real-time performance metrics, industry-leading analytics, and customizable trading strategies. Mercuria is a leading independent energy and commodity group operating in over 50 countries with over 1,100 professionals. They are developing a 20-gigawatt renewable energy portfolio and directing more than 50% of their investments into the energy transition. PowerBidder Pro offers a scalable solution in line with Mercuria's renewable development strategy to seamlessly manage trading strategies across an entire footprint and across different power markets. I would note that this was a competitive process where STEM again exceeded all other offerings with robust, differentiated economics and granular control of energy storage assets. We are also announcing that we recently signed a PowerBidder Pro contract for a portfolio of assets controlled by 2 community choice aggregators in California. This is our first utility-scale software-only deployment in CAISO. This win highlights the momentum we continue to see in the public power, municipal and co-op space, as we noted last quarter, with STEM building to an approximate 15% market share in this fast-growing segment of the front of the meter market. In both cases, our software will be integrated into existing assets which underscores our focus on turning contracted revenue into annual recurring revenue as quickly as possible. Please turn to Slide 8. In ERCOT, our data science team has demonstrated Athena delivers best-in-class performance, as evidenced by our white paper published in December 2023. We showed through backcasting simulation that STEM outperformed competitive software offerings by 28% on average and as high as 90% in one case. We see two reasons for Athena's outperformance. First, highly accurate price forecasting. We generated 53% higher revenue than naive strategy that assumes historical prices persist in the future. ERCOT is an energy-only market with high price volatility, so advanced forecasting capabilities are essential. STEM is a market leader with a significant data advantage that has sites operating across multiple geographies. Second, advanced optimization. Our AI-driven solution takes into account thousands of individual variables and constraints to optimize across both day-ahead and real-time energy markets and different ancillary service products. Athena continuously co-optimizes across all market products as their values change over time. And again, our experience and data advantage allow us to consistently improve our optimization algorithms leading to superior asset performance. The white paper is published on our website and details a rigorous methodology to conduct these simulations, ensuring adherence to ERCOT market participation rules with capacities ranging from 10 megawatts to 100 megawatts across a diversity of electrical zones. Finally, it's worth noting that STEM's program management team, which adds a human touch, could enhance the automated results. I encourage everyone to download the white paper from our website to learn more about our analytical processes and performance. Our data science team has content showcasing our technology offerings for the ERCOT market, public power and solar plus storage, among others. Moving to Slide 9. Looking ahead for the balance of 2024, we continue to see positive macro tailwinds. Demand for energy storage and solar remains robust, catalyzed by sustainability initiatives, the Inflation Reduction Act decreasing battery prices and improved project economics. Over the last year, we have seen the solar business return to double-digit growth with 4 consecutive quarters of revenue and AUM growth. Solar software has performed increasingly well and remains in high demand from customers. As a market leader for energy storage and solar asset performance management solutions, we expect this robust demand will continue to drive strong, high-margin software revenue in both solar and storage. Energy storage hardware costs continue to decline, driving better economics for our customers and increased overall TAM and demand for our services. In the U.S., we are encouraged by the domestic supply continuing to ramp up and note that 38 battery gigafactories are either operational, under construction, or planned for construction. We believe that the U.S. domestic content provides compelling opportunities for improved project economics and are pursuing a vendor-neutral strategy to offer our customers access to top-tier suppliers without committing volumes to any single supplier. We are seeing favorable conditions in the supply chain with battery cell manufacturers potentially entering the market to offer integrated hardware solutions. We expect this will drive increased competition and better hardware costs and terms. This benefits our customers' project economics, enhancing our market opportunity and enabling geographic expansion. In addition to federal incentives, we are seeing more and more states introduce mandates for energy storage, including recent mandates in Maryland, New Mexico, and Michigan, which are targeting multiple gigawatt hours in each market. Overall, the macro environment remains favorable for STEM and we're excited to expand our software and services leadership position. I'll now turn the call over to Bill.

Thanks, John and thanks to everyone for joining us on the call today. I'll start on Page 11 with the results of our fourth quarter of 2023. The revenue increased 8% to $167 million as compared to the fourth quarter of 2022. That performance was despite interconnection and permitting delays and slower-than-expected deliveries from hardware suppliers, which negatively impacted our storage business. Solar revenue rose 27% year-over-year, faster than the growth in the U.S. C&I solar market as Power Trek continues to gain share with customers and differentiate itself in the market. In the fourth quarter of 2023, GAAP gross margin was relatively flat year-over-year, while non-GAAP gross margin expanded nearly 20% from 11% to 13%. GAAP gross margin was negatively impacted by one-time excess supplier costs and liquidated damages in the quarter. As John previously noted, we met our commitment to achieve positive adjusted EBITDA in the second half of 2023. That was a milestone achievement for our business and we are proud of our team for reaching this goal. Fourth quarter adjusted EBITDA was $4.6 million and second half 2023 EBITDA was $3.7 million. The year-over-year increase of $14 million in adjusted EBITDA was due to higher revenue, expanded gross margins, and lower cash operating costs. We continue to drive operating leverage and efficiencies with strict cost controls. For instance, cash OpEx declined approximately 16% sequentially. We recently restructured our BTM business to prioritize targeted opportunities, leading with software and services with partner channels and a direct-to-market approach. Finally, in the fourth quarter of 2023, operating cash flow was a negative $2.1 million, representing a year-over-year improvement of approximately $35 million. This is a significant improvement that positions us well to generate positive operating cash flow and fund operations in 2024 without the need to issue any additional equity or equity-linked securities. Cash operating expense for Q4 2023 was 13% of revenue as compared to 19% in Q4 2022. For the full year, we achieved cash operating expenses of 24% of revenue versus 31% in the full year 2022, roughly flat at $111 million in both years. We have added a new slide to the appendix that shows the reconciliation of GAAP to cash operating expenses and we do not forecast a meaningful increase in cash operating expenses in 2024. We ended 2023 with $114 million of cash and cash equivalents, which is below our goal, in part due to delayed customer payments, a significant amount of which was collected in the first week of January, including a $22 million payment in that week. Turning to Slide 12. CARR or Contracted Annual Recurring Revenue was increased 4% sequentially and 39% year-over-year to $91 million, exceeding our original guidance of $85 million at the midpoint and in line with our increased guidance range of $90 million to $95 million we provided last quarter. Storage assets under management grew 10% sequentially to 5.5 gigawatt hours and are now a 77% year-over-year increase. Backlog continues to predict future revenue growth with a sequential increase of 5% or $92 million, reflecting the impact of current period recognized sales and bookings. Backlog increased 99% year-over-year as we continue to execute large FTM transactions in the muni and co-op spaces and advance our software and professional services offerings. We focus on high-margin projects which meet our cash flow and project timing goals in markets where we can deliver differentiated services to our customers, which is reflected in the growth of the business. Solar assets under management increased 5% sequentially to 27.5 gigawatts. This was the fourth quarter in a row of AUM growth on the solar side of the business. And as John previously mentioned, we are confident that the solar business is back on track. We also continue to transition the older platforms to Power Track and can report that we have now converted nearly 50% of the customers and expect to conclude that process this year. This transition will maximize profitability and customer retention. Turning now to Slide 13. Annual revenue increased 27% to $462 million for the full year. Full-year 2023 sales were impacted by the revenue adjustment made in the third quarter as well as delays due to supplier permitting issues offset by positive results in the solar business. Solar business, as mentioned, grew 27%, reflecting the strong rebound in 2023 after a rough 2022 which was dominated by regulatory issues. GAAP gross margin was 1% for the full year 2023 versus 9% in the full year 2022. However, non-GAAP gross margin increased from 13% to 15% in the full year 2023, which was consistent with the 2023 guidance. The increase in the margin reflects a focus on higher-margin transactions in markets like public power, where we demonstrate differentiated software value to our customers. Adjusted EBITDA improved $27 million to negative $19.5 million in the full year 2023, reflecting the focus on accretive hardware sales, increasing in software and service sales, and strict cost controls on the business. With the achievement of positive adjusted EBITDA in the second half, we expect to generate positive adjusted EBITDA for the full year 2024, while focusing on free cash flow. Moving to Slide 14 and 15 which includes our 2024 guidance. Starting with revenue, we expect to recognize between $600 million and $700 million of revenue in 2024 and expect to see the typical seasonality during the year. Similar to prior years in the larger renewable sector, seasonality of revenue is back-end weighted, driven by the timing of the equipment delivery, increasing product sizes and our customers' tax equity and project financing considerations. We expect non-GAAP gross margin of 15% to 20% in 2024. We continue to focus the sales team on the highest margin opportunities, including software and professional services deals, where we can drive differentiated economics for our customers and for STEM. With respect to bookings, we expect to contract between $1.5 billion and $2 billion in 2024. The bookings have become increasingly lumpy and more challenging to predict with precision because of the larger project sizes. As a result, we have decided to stop providing quarterly guidance going forward but we will report the bookings metric quarterly. We expect CARR to exit 2024 at a run rate between $115 million and $130 million. This is a function of our bookings growth, including the software-only deal momentum we have previously mentioned. We expect adjusted EBITDA to be positive for the full year 2024 with a range of $5 million to $20 million. Finally, given the importance of free cash flow generation and our recent achievement of positive adjusted EBITDA, we have added a new key metric, operating cash flow, that underscores our commitment to profitable growth, as highlighted in our guiding principles. We expect to generate more than $50 million of operating cash flow for the full year in 2024 without the issuance of additional equity or equity-linked securities. Now to Slide 15 for more context around our 2024 guidance ranges. Our revenue range of $600 million to $700 million leaves room for potential upside from large FTM deals in the pipeline. As our focus on working capital increases and the project sizes increase, armored timing becomes increasingly lumpy and results in variable revenue on a quarterly basis. For example, our average FTM deal has more than doubled in 2022 and almost doubled again in 2023. Our non-GAAP gross margin range of 15% to 20% is driven by the expected mix of hardware and software revenue in the coming year. Improvement in potential upside is driven by professional services revenue and the assumption of a conservative pace of activating non-operational CARR using historical trends. The bookings range of $1.5 million to $2 million assumes modular ESS bookings may include hardware if STEM working capital is not utilized in these projects. As you are well aware, we have been offering customers a modular solution to source their hardware, what we call the modular ESS offering. We source different hardware components from different suppliers instead of the full BESS from one supplier. When we launched the offering, we assumed that our customers, especially the largest one, would procure their own batteries and we would source the rest of the components for them. During the sales cycle, we have found that many of our customers still want us to procure the battery packs on their behalf. We have learned that for many customers, energy storage is still a nascent industry and customers value our superior supplier relationships, configuration, expertise, and insight on various supplier cost roadmaps and performance. There is differentiation in our hardware offerings and customers value. The adjusted EBITDA range of $5 million to $20 million is driven by the expectation that we will meet our revenue and margin targets and continue to drive operating leverage. Our CARR range of $115 million to $130 million is driven by software-only deal momentum. And finally, operating cash flow is expected to be greater than $50 million, driven by a shift to adjusted EBITDA positive and reduction in working capital intensity. Through disciplined management of operating expenses, we are on track to reach our long-term cash OpEx goal of 10% to 20% in 2024. And now turning to Slide 16. As John mentioned, one of our guiding principles this year is building software services revenue which includes converting contracted ARR to revenue on the income statement. As you can see from the charts on the right, we have a significant amount of recurring revenue that has not been recognized, largely due to delays outside of our control. This represents substantial earnings power that will be recognized as systems are commissioned and become operational. We expect to exit 2024 with around $65 million of recurring contracted gross profit embedded in long-term contracts. This would nearly cover 2/3 of our expected cash OpEx run rate. As a rule of thumb for storage, every $1 billion of bookings represents around $23 million of recurring revenue and around $10 million of gross profit annually. Solar recurring revenue has gross margins of approximately 80% and converts from CARR to ARR within 3 to 4 months. We essentially have 2 cohorts of contracted annual recurring revenue. Those systems that were booked prior to 2023, which include the impact of logistics challenges and constrained product availability in the supply chain. These customers often executed bulk hardware buys in advance of final site locations. As a result, timelines are activating software for this group have been affected. For the second cohort, we expect the CARR to ARR conversion to trend to the lower half of the 2- to 12-month time frame represented here. We have several initiatives in place to accelerate the conversion of CARR to ARR through 2025 with software-only offerings, a focus on public power where the buying entity controls permitting and interconnection timelines, and the operational and contracting changes included in commencing software revenue once the system is energized versus waiting for the final approval to participate in wholesale energy markets. Turning to Slide 17. You have heard us mention on the call multiple times that we remain disciplined on growing operating expenses. Here, we present details behind the significant progress we have made in managing expenses. We are on track to achieve our long-term OpEx goal as a percentage of revenue of 10% to 20% in 2024 ahead of schedule. In 2023, we committed to reaching less than 25% cash OpEx as a percentage of revenue for the full year and we beat that coming in at 24%. Importantly, in 2023, we decreased our average wage expense by 31% while nearly doubling our contracted backlog year-over-year. As I noted earlier, we held cash OpEx flat in 2023 at $111 million as compared to 2022 and do not expect a meaningful increase in cash OpEx in 2024. We view the cash OpEx performance as critical to the achievement of our guiding principle for 2024, generating operating cash flow of at least $50 million. Turning to Slide 18. Since going public, we've seen strong growth in virtually all of our key metrics and we are proud of what we have achieved. Our CARR will nearly double over the next 2 years and we will continue to focus on the conversion of CARR to ARR. For revenue, we have shown steady growth driven by execution even in the face of industry headwinds. We added $27 million of adjusted EBITDA between 2022 to 2023 and we expect to add an additional $25 million to $40 million of adjusted EBITDA in 2024 per our guidance. And for operating cash flow, we are confident we can generate inflows this year as we increase our profitability and reduce our working capital intensity. Much like our execution in the second half of our 2023 EBITDA goal, we view our guiding principle for 2024 to center around operating cash flow of at least $50 million.

Thanks, Bill. Wrapping up on Slide 18 with our key takeaways. Our 2024 outlook is supported by solid 2023 execution. In 2023, we achieved positive adjusted EBITDA for the second half and fourth quarter, upholding our commitment to this important milestone set forth two years ago. In addition, we met our gross margin, bookings, and CARR targets for 2023. Through disciplined management of operating expenses, we are on track to reach our cash OpEx target in 2024 and do not expect a meaningful increase versus 2023, which was $111 million. We believe that 2024 is set up as an inflection point for building long-term profitable growth. We expect to generate free cash flow to fund operations without issuing equity, build recurring software revenue, and extend our technology leadership position. Before we turn the call over to questions, I have a couple of additional updates. First, we've initiated a director search with software industry expertise to be added to our Board of Directors, consistent with our long-term strategic direction. I would also like to announce that Bob Schaefer, the Co-Founder of Also Energy and a terrific asset to our integration efforts and a great business partner to me personally will be retiring on May 3. Bob has been the President of Also Energy, a business he cofounded in 2007. He and the team built a solar software monitoring platform that is market-leading and continues to gain share. We wish him and his wonderful wife, Donna, all the best on this next chapter and he will always be part of the STEM family. With that, I want to thank shareholders, employees, customers, channel partners, and suppliers. And now operator, let's open the lines for questions, please.

Certainly. We'll now begin the question and answer session. The first question comes from Brian Lee from Goldman Sachs.

This is actually Nick Cash on for Brian Lee. Can you guys hear me all right?

We can.

I was wondering why the revenue guidance seems somewhat limited considering your significant growth in the backlog and the indication that the demand environment is still strong. Additionally, with input costs decreasing, this might increase project internal rate of returns, leading to further demand. Could you provide more insight into your backlog conversion and cycle times?

Yes. Thanks. This is John Carrington. A couple of quick points. If you look at Slide 15, you'll see various commentary about the guidance. The main point to highlight is that we have several large deals that could increase our numbers. We will update everyone as those deals develop. There's some positive commentary on Slide 15 in the deck. Bill, do you have anything to add?

No. I think the other piece that I would say just more specifically is that the type of deals that we're signing have grown both in size and complexity, which means that they're longer duration. So for sure, one of the things that we've talked about here consistently is that backlog is getting longer. And so that's going to have an impact on the revenue guide. And I think, as we said in the deck in the prepared comments there is opportunity potentially for some deals. And if that happens, we'll be able to execute on that.

The next question comes from Dylan Nassano from Wolfe Research.

I want to go back to the opening comments. It sounds like you're pretty clear that you don't plan to issue equity this year. But do you see any potential for maybe needing to pull some other funding levers just to kind of work through the quarterly lumpiness as you get to the $50 million of operating cash flow?

Thanks, Dylan. We do not. I mean our prepared remarks are pretty clear around that. And so we're confident in that statement.

Great. And then I want to go back to the comment on domestic content and how that's favorable for project economics. Can you just provide a little bit more color around how STEM specifically sees that benefiting?

Dylan, this is Prakesh Patel. I think it helps in a couple of ways. First, the domestic manufacturing partners that we're engaged with, they receive certain manufacturing incentives. And then, of course, our customers can benefit from domestic ITC or other incentive adders. So in aggregate, all of these incentives improve project economics and in those cases, allows us to negotiate more favorable pricing or better margins. So that's how it flows to us. As you know, we don't manufacture hardware, so we're not direct beneficiaries of those incentives.

The next question comes from Thomas Boyes from TD Cowen.

Great. Maybe first one, obviously, great to see the agreement with Mercuria. Given they have a 20-gigawatt renewable energy portfolio, how does that kind of equate to an overall market opportunity for STEM, similar to the 10-gigawatt hour energy storage pipeline that was identified for SB Energy in China? Get some insight there.

Yes. Thomas, this is John. I'd say a couple of things. And I think you might have been one of the individuals on the call that were there for the demo at RE+ on PowerBidder Pro that we launched in the third quarter. And look, I'm really excited about this one because obviously Mercuria is a very significant player. What they've publicly committed to is directing over half or at 50% of their investments into the energy transition and planning a 20-gigawatt renewable energy pipeline. We'll work closely together with them as it relates to those projects. At this point, we're not committing to how much of that piece of the 20 gigs we'll go after that we will close, I should say. So more to come there but I think it's just a real statement of how important and valuable this PowerBidder Pro technology is for someone with the domain expertise that Mercuria represents.

I appreciate it. I did see the demo there at RE+; thought it was just great. As a follow-up, from an operations standpoint, is there an opportunity to transfer additional headcount to lower geographies? Or is that kind of largely been exhausted with everyone that can kind of move to India already having shifted there?

No, I’d say we're really continuing to focus on that initiative. The India Center of Excellence is improving as we bring more people on board. Besides direct sales, we’ve examined almost every function for potential relocation to India. This strategy has yielded positive results. We will always have personnel in various regions where we operate, but the slide illustrating a 30% reduction in wages clearly demonstrates our commitment. We plan to further explore opportunities in India as part of our ongoing strategy. Additionally, on the software development side, we benefit from a continuous development cycle that enhances our ability to create new applications, which we see as a sustainable option for the future. Our teams are collaborating effectively across different functions.

Great. Now that's helpful. And then if I could just sneak one more and then I'll jump back in the queue. I just wanted to get some insight on maybe some of the cross-selling opportunities that you have previously identified with the Also Energy portfolio. I think we saw the first really kind of conversion coming through last quarter. And I was just wondering how you're thinking about that opportunity to play out this year.

Thomas, this is Prakesh. We're pleased with our initial progress. In the full year '23, we highlighted some notable achievements and will continue to make progress in that area. As mentioned in the call, BTM is now primarily focused on exclusive software services, which will enhance our ability to cross-sell.

The next question comes from Justin Clare from ROTH MKM.

So I guess, first off, just on the 2024 guidance, I was wondering if you could give us a sense for what your expectations are in terms of the mix of hardware sales versus software sales or potentially give us an idea of what the growth expectations are? I know it sounds like many of your customers may prefer you to be sourcing the hardware for them still. So I also wanted to think about that in terms of the context of your long-term targets. So your hardware target of 25% to 35% growth, service is 65% to 85%. Should we be thinking about a change in those targets?

Thank you for the question. Historically, we have been at around 85% hardware and 15% software. We believe that over time, the value of software will continue to rise. However, the profit margins on hardware, especially storage hardware, are quite high, making it challenging to significantly alter that ratio. What you can expect over time is growth in software and services, which will lead to a larger absolute dollar growth in hardware.

Got it. Okay. And then just looking into Q4, it looks like the storage software revenue is flat year-over-year. So you could just help us understand why we didn't see more growth given the growth in the storage AUM? Is it specific issues with interconnection or permitting? And then, just wondering if you can give us some insight into whether those could be resolved as we move into 2024? Are there specific large projects that could come online potentially early in the year?

Yes, you are correct. There are issues related to interconnection and permitting. We have some large projects that we’ve discussed in previous quarters, including United, which is expected to launch in the first half of this year. This represents over 300 megawatt hours of projects coming online, and we are excited about that. We are actively working on several initiatives mentioned in our slide deck to expedite the conversion of CARR into ARR. This is a significant focus for us. One point made in the slide deck was that if we convert half of the CARR into ARR, it could yield an additional $20 million in revenue. There is considerable opportunity for us to enhance our services and positively affect our gross margin as well. We are investing in our deployment teams to accelerate ARR growth through the conversion of CARR, and we are concentrating on these efforts for 2024.

Justin, I'd highlight Slide 16 along the lines of what Bill said. There's some, I think, very good color there. And actually, it's the pro serve side of the business that we're very excited about as well. And we feel like that will be a continued growth area for us and upside to the numbers. So I encourage you to take a look at that. We're happy to follow up on any specific colors.

The next question comes from Julien Dumoulin-Smith from Bank of America.

Guys. This is actually Cameron Lochridge on for Julien here. Just wanted to come back and again, congrats on reaching the positive adjusted EBITDA figure in the fourth quarter. If we think about the longer term, right, understanding that there is an effort to accelerate that CARR conversion to the income statement. How are we thinking about the 2025 software and services target that you guys played out at Investor Day, just that 65% to 75% revenue CAGR that you guys have talked about? What are we thinking there? Is that still on the table? And if not, when can we kind of expect an update there?

Yes, I have a few points to share. First, we are not providing an update on the long-term forecast during this call and are primarily focused on 2024. The numbers Bill just highlighted indicate that if we convert 50% of the 2023 CARR, it would generate $20 million in services, which represents a 60% year-over-year growth, excluding the professional services I mentioned earlier. This does not factor in ProServ. We'll update these figures as we progress, but we are confident in the amount of CARR. As mentioned in the prepared remarks, transitioning from CARR to ARR is a key priority, and we have several initiatives underway, including the PowerBidder Pro event managers as software-only offerings and our commitment to public power, which we discussed in this call and previous ones. These entities are significant because they can influence the permitting and interconnection timelines Bill referred to, along with some operational and contracting adjustments we are implementing to accelerate revenue collection.

I'd like to add one more point. Looking at our guidance for 2024, we do not expect an accelerated software conversion, yet we still aim to meet our EBITDA and cash flow targets. There is potential for growth from converting CARR to ARR and gaining traction in the professional services area. Similar to 2023, even if we face some challenges, we believe we will achieve our EBITDA and free cash flow targets. Regarding the figures, particularly the free cash flow aspect, we have not experienced significant contract cancellations. Therefore, by generating the anticipated free cash flow, we position ourselves well to seize software conversion opportunities. When we consider being EBITDA positive and generating free cash flow, it presents a valuable opportunity, especially since the scale of our deals has increased and these will remain viable when the systems are operational, ultimately reflecting positively on the income statement and generating significant cash and gross margin.

This concludes the question-and-answer session. I would like to turn the conference back over to John Carrington for any closing remarks.

Great. Thank you, Brenda. And look, we look forward to speaking with you during our 1Q earnings call. And thank you all for joining us today.

This concludes today's conference call. You may disconnect your lines. Thank you for participating, and have a pleasant day.
