Arun Narayanan
Thank you, Erin. Good afternoon everyone and thank you all for joining us today. I am pleased to be speaking with you one year after assuming the role of CEO and I could not be more proud of what the STEM team has accomplished over the past 12 months. Best in class execution, unwavering commitment to our customers and each other, and disciplined financial performance. 2025 was a transformative year that methodically yet decisively reshaped STEM into a software centric, operationally disciplined organization. Every commitment we made and the proof of our strategic transformation is in the results. Today I will take you through a look back on our fourth quarter and full year accomplishments. After that, I will walk you through our 2026 priorities and show you how we are determined to become the operating system for clean energy projects. And finally, I will give you a preview of guidance for the year ahead. Brian will follow with the detailed financial results and our complete 2026 outlook. In 2025 we delivered on guidance across every metric. Full year 2025 revenue grew 8% year over year to $156 million, with over 55% of that revenue coming from software and services. Evidencing our successful and ongoing transformation, Software Services and Edge hardware revenue grew by 25% year over year to $141 million year end ARR grew 16% year over year to $61 million. In 2025, we substantially expanded gross margins and considerably reduced our operating expenses. We achieved three consecutive quarters of positive adjusted ebitda, resulting in our first ever full year positive adjusted EBITDA of $7 million. We also achieved positive operating cash flow for full year 2025, another first and major accomplishment in the company's history. Throughout the year we continue to deepen and expand our PowerTrack platform, delivering meaningful improvements in platform stability, performance and customer experience. We added 6 gigawatts of solar assets to a total of 36 gigawatts under management and added $7 million in Powertrak ARR to reach $41 million in 2025. We accelerated our R&D efforts, leveraged AI tools and rebuilt our product roadmaps. We successfully launched two new products last year. Both products, PowerTrack Energy Management System (EMS) and PowerTrak Sage, have resonated well with our customers and we are encouraged by the early traction. We launched Powertrak Energy Management System (EMS) in September 2025 and it is a premier solution for utility scale projects. This morning we announced a new engagement with Everyray, a German clean energy developer and EPC. This 100 megawatt hour deal further expands STEM's presence in Germany and reinforces Powertrak Energy Management System (EMS)'s role as the control backbone for sophisticated utility scale storage deployments across Europe and other international markets. Commercial operations for those deployments are expected to commence in the summer of 2020. Our expansion into the utility scale market, both domestically and internationally, gained meaningful traction in the fourth quarter, with utility scale bookings increasing 10% sequentially. Notably, nearly all fourth quarter utility scale bookings were driven by international solar projects, underscoring growing demand in global markets. I talked with you about PowerTrack Sage, our AI powered assistant, in previous calls and I continue to be excited about it. We deployed PowerTrack Sage in the fourth quarter to more than 80 customers for a beta trial and the feedback has been overwhelmingly positive. PowerTrack Sage will be generally available at the end of this month. At launch, we will deploy a light version across the entire PowerTrack customer base, embedding AI assisted capabilities into the core platform from day one and accelerating adoption at scale. This universal rollout ensures immediate value realization while positioning AI as a foundational component of the PowerTrack experience. For customers seeking deeper automation, advanced analytics and expanded workflow functionality, we will soon offer premium tiers at incremental cost, creating a clear pathway for upselling monetization and long term platform expansion. Finally, our managed services business delivered solid fourth quarter performance highlighted by a new brownfield agreement. Under this deal we will operate and optimize A4Site energy storage portfolio for a Southern California utility. Our services include real time asset monitoring, enrollment and dispatch into California demand response programs, performance reporting to optimize site dispatches, and energy cost savings and more. This is a solid proof point for our differentiated managed services capabilities and validation of our brownfield strategy. Overall, the result of 2025 is this stem has established a stable, increasingly profitable software centric business model. 2025 was ability 2026 is about operational leverage and building for scale, so let's dive in. As we enter the new year with strong fourth quarter momentum, we are focused on three new priorities. Priority number one driving operational leverage, priority number two continuing to strengthen our core business and priority number three, building the foundation for accelerated growth in 2027 and beyond. Now let's dive deeper into each of these in turn. First, driving operational Leverage we have built a sustainable business model and in 2026 we intend to demonstrate the leverage it creates. Our software centric model delivers predictable high margin revenue and cost. Discipline is now embedded in the culture of this company. In 2026 we will continue integrating AI across the organization to drive productivity improvements and we will maintain our relentless focus on cost reductions, cash conservation and working capital management. Second, strengthening our core business we remain focused on driving core platform excellence for PowerTrak in 2026. The platform maintains its market leading position in commercial and industrial solar monitoring in the us. This year we will deliver further platform stability, scalability and simplified intelligent UI updates that drive customer value and retention. The domestic CNI solar market, where we already hold significant share, offers moderate growth in 2026, but this is a stable high retention base that continues to generate recurring revenue. Additionally, we are targeting a brownfield strategy to further increase our market share as well as a range of other adjacent offerings. Our other core business, managed services for energy storage continues to be a differentiated offering that sets STEM apart from competitors. Our Brownfield strategy remains a key focus as does actively pursuing greenfield opportunities. We are scaling in existing domestic markets, leading with our proof of performance and winning with our differentiated offerings. And finally to priority number three, building for growth in 2027 and beyond. Outside of our core CNI solar and storage businesses, we are focused on expanding our utility scale footprint domestically and internationally. We are targeting key markets across Europe, leveraging local support infrastructure that we have built and continue to invest in both the domestic and international utility scale storage and Solar markets are growing and we are well positioned to capture rising demand and take share. Powertrak Energy Management System (EMS) helps us differentiate in the utility scale space by providing a solution for hybrid solar plus storage sites and also standalone best sites which are increasingly common in the utility scale market. We expect meaningful revenue conversion of Powertrak Energy Management System (EMS) bookings to begin at the end of 2026 and the beginning of 2027. While we are bringing Powertrak Energy Management System (EMS) to market this year, we are also exploring other ways in which our team's expertise and our technology can deliver value. First, as part of our suite of professional services offerings, we are developing AI services that leverage our domain expertise and operational knowledge to help customers identify, prioritize and deploy the current iteration of generative AI solutions in a way that generates real economic outcomes. These offerings are distinct from PowerTrack SAGE and they are focused on helping customers unlock value across their broader operations. And our second area of opportunity is with data centers. More and more we are seeing data centers adopting renewables as a power source. We believe STEM has the foundational technology and deep expertise in both solar and storage to be a meaningful player in this market. I am encouraged by these options. We see a natural extension of our existing capabilities driving our entrance into the space and I look forward to updating you all on our progress in the coming quarters. 2026 is an optimization year focused on margin expansion and operating leverage. While we continue to invest selectively in the capabilities that will drive scale in 2027 and beyond, I want to be deliberate about that framing because it shapes how you should think about our trajectory. PowerTrack Energy Management System (EMS) was launched in late 2025. It accelerates through the end of 2026 and meaningfully scales in 2027 and beyond. Our utility scale team is building meaningfully in 2026 and this foundation will drive us towards taking share in 2027 and beyond. We believe that the market positions we are strengthening. Business on technology, our AI integration, improving stability and scalability on markets, international expansion and utility scale expansion here and abroad on products and offerings a comprehensive suite from solar monitoring to storage optimization on operations, building operating leverage and driving operational excellence. Expanding the value chain of our offerings today sets up the foundation for future growth. This is important to note because it ties into our core software centric vision for stem. We are determined to become the operating system for new energy projects across solar storage and hybrid assets and in different market segments and geographies. Before turning it over to Brian, let me introduce the key themes of our 2026 guidance. We are entering the year with a strong foundation from our 2025 execution and believe we are well positioned to execute on our commitments. We expect our software centric strategy to drive moderate top line revenue growth, strong gross margins and significant adjusted EBITDA expansion, supported by continued software momentum, our expanding product suite and the operational leverage we have built into the business. Brian will provide a more detailed look at our 2026 guidance and also dive deeper into our fourth quarter and full year 2025 financial results. With that, let me pass over the call to him.
Brian Musfelt
Thanks Arun and hello everyone. Let's walk through the results. For the full year 2025 we were in line or above all of the financial expectations we outlined on our third quarter call. We exceeded our profitability guidance, demonstrating the dedication to operational discipline that runs through this organization. For the full year of 2025, total revenue was 156 million, up 8% year over year. Most importantly, revenue from Software Services and Edge Hardware, the core of our software centric model was up 25% year over year to 141 million. Battery hardware resale was 15 million for the year, consistent with our strategic de emphasis of lower margin business. This shift in revenue mix is precisely what we committed to delivering and is reflected in our improved gross margin performance this year. Turning now to the Fourth Quarter, PowerTrak software revenue continued its strong performance, growing 14% year over year and Edge hardware revenue grew an impressive 21% year over year. Managed service revenue was up 51% year over year, driven in part by one time performance based revenue. Where we exceeded asset operational targets, battery resale revenue was down from 27 million to less than 1 million year over year. As expected, project and professional services revenue increased significantly year over year driven by approximately 11 million of one time DevCo revenue recognized in the Fourth Quarter. Excluding DevCo, Fourth Quarter project and professional services revenue was up 27% year over year. I also want to note that as of the end of the year, we have sold or written off all of the project assets associated with Devco from our financial statements and we do not intend to make any further investments in Devco assets moving forward. Now let's take a look at gross margins for the full year 2025. We achieved record Generally Accepted Accounting Principles (GAAP) gross margins of 38% and record non Generally Accepted Accounting Principles (GAAP) gross margins of 46% driven by decreased battery hardware sales, a favorable software and service revenue mix and improved Edge Hardware margins. Fourth quarter Generally Accepted Accounting Principles (GAAP) gross margins were 49% and non Generally Accepted Accounting Principles (GAAP) gross margins were 45%. Continuing our strong results, you can Again, find the detailed revenue and margin breakdowns we introduced last quarter in our supplemental materials on our IR website. Full year 2025 cash operating expenses were down 41% from 2024 and Fourth Quarter cash operating expenses were down an impressive 50% year over year. We are building sustainability into our cost structure, not temporary reductions but permanent structural efficiency while simultaneously developing new products and entering new markets. That combination is the foundation of our operating leverage thesis moving forward into 2026 and beyond. The improved margins and significantly reduced OPEX in 2025 drove positive adjusted EBITDA of approximately 7 million for the year above the high end of our guidance range and representing the first year of positive annual adjusted EBITDA in STEM's history. We achieved three consecutive quarters of positive adjusted EBITDA this year with the Fourth Quarter coming in at 5 million, a 30% improvement from Fourth Quarter of 2024. The improvement was primarily driven by improved gross profits and reductions in operating expenses, with modest additional benefit related to the final sales of the Devco project assets. Full year operating cash flow was 7 million, slightly above the high end of our revised guidance. The Fourth Quarter benefited from the sale of our Devco project assets and other favorable working capital movements. We ended the Fourth Quarter and full year 2025 with $49 million in cash, up from $43 million at the end of the third quarter. This is a solid liquidity position that supports our 26 plans. And now turning to our operating metrics, Fourth Quarter bookings were $33 million, up slightly from last quarter due to increased software and service bookings offset by decreased battery hardware bookings. Contracted backlog was 21 million, down 4% from 22 million last quarter due to decreased battery hardware bookings. Our end of year 2025 backlog is 2% higher than it was at the end of 2024 and excluding battery hardware is 23% higher than prior year. CAR decreased 3 million sequentially to 67 million due to lower managed services bookings and the cancellation of a managed service customer agreement. This customer cancellation, driven by adjacent non scalable product requests outside of our roadmap impacted car by 3 million, ARR by 1 million and AUM by 0.1 GWh. Despite this cancellation, total company ARR grew 1% sequentially and 16% year over year to 61 million supported by increased Powertrak software bookings. Turning now to our full year 2026 guidance, we are encouraged by the strong momentum we carried throughout 2025 and that we bring forward into 2026. We expect that performance to accelerate as we advance throughout the year. For revenue, we expect total revenue in the range of 140 to 190 million dollars. Within that range, we expect 130 to 150 million to come from high margin software services and edge hardware revenue, our core business. We expect the remaining balance of up to 40 million to be driven by battery hardware resales, which remain opportunistic and are not a strategic priority. We expect non Generally Accepted Accounting Principles (GAAP) gross margins of 40 to 50%, broadly in line with our 2025 performance. Higher battery hardware resales would cause gross margin percentage to trend toward the lower end of that range. We expect adjusted EBITDA of 10 to 15 million representing approximately 85% growth at the midpoint versus full year 2025, driven by revenue growth, operating expense, discipline and increased operating leverage. We expect operating cash flow of 0 to 10 million, reflecting stable cash generation from operations for the year. And finally, we expect ARR of 65 to 70 million representing approximately 10% growth at the midpoint. Continuing the momentum from 2025 I'm extremely proud of what the team has accomplished in 2025 and we are continuing to build a strong foundation into 2026 that sets us up for accelerated growth in 2027 and beyond. And I will now pass the call back over to Arun for closing remarks.
Arun Narayanan
Thank you, Brian. As I reflect on 2025, I am struck by the scope of what our team accomplished. We delivered a business transformation, executed a financial turnaround, completed two new product launches and demonstrated a clear strategic path forward. We said we would do it and we did it. As I look ahead through the remainder of 2026 and beyond, I am confident we have three clear strategic priorities to guide us in 2026. We have an ambitious but achievable adjusted EBITDA target and multiple growth drivers that de risk execution. And last but certainly not least, we have a team with a proven track record of executing. Our long term vision is to build a scalable, profitable software and services company that holds a market leadership position in clean energy intelligence. STEM is uniquely positioned to capitalize on the ongoing clean energy transformation with a market leading platform, a growing product suite and an expanding global footprint. To our customers, we are grateful for your continued partnership and trust to our investors. We appreciate your support through this transformation and your confidence in our vision. To our team, your execution through a challenging transformational year reflects your talent, your resilience and your dedication. Thank you. With that, I will ask the operator to open the line for questions.
OPERATOR
Thank you. We will now be conducting a question and answer session. If you would like to ask a question, please press STAR and the number one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press Star and the number two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment while we poll for questions. Our first question comes from Justin Claire with Roth. You may proceed with your question.
Justin Claire
Hi, thanks for taking our questions here. Wanted to start off on the powertrak EMS launch. So you mentioned that you could see an acceleration for Powertrak EMS in 2026, but more meaningful scale in 20. So just wondering how we should think about the timing of bookings for the product. Could we see an increase as early as Q1 or Q2? Or is that more of a second half dynamic? And then just wondering if you could talk through the typical sales cycle and lead times for the EMS deployments.
Arun Narayanan
Thank you for your question. This is Arun. Good to hear from you again. Powertrak EMS was launched in September 2025 and the reason we are so excited about it is it is the first time we are able to address a solar and storage solution and address a customer's need completely. If you think about even the press release that we put out today, we are able to work with newer customers in international markets as well as customers domestically as well. And the main sort of aspect of these solutions are geared towards utility scale projects. Inherently they are a longer life cycle and this means that we need to give time to build the business, build the pipeline, engage with the customer and make sure that the solution is a good fit and then work with the customer through the commissioning of the project all the way to revenue recognition. So it does take some time and we are working on that today. Okay. And then I guess, curious, would you anticipate the revenue, Is it a recurring revenue stream, and could you also help us understand that? Yeah, so it just depends on the components, right? So think about a project that we deploy. It would have hardware, software as well as service components, and the mix of these three components would be the totality of the contract that we are executing. Depending on the component we're talking about, the revenue recognition would follow specific timeline. So maybe hardware is recognized immediately upon delivery, but the service component would need to run through the commissioning life cycle. So if you look at the everyray press release that we announced today, we are encouraged by the feedback that we're getting from our customers that's a hundred megawatt hour project that we have deployed. And just connecting back to the remarks that we made earlier, we are looking at 2026 as a way to build the foundation and then see 2027 as the point at which we're able to scale the revenue.
Justin Claire
I see. Got it, got it. Okay. And then just on the 2026 guidance, it does look like the battery resale revenue up to 40 million. That's a fairly meaningful increase potentially from the 2025 storage resale revenue of 15 million. So just wondering if you could speak to what's driving the increase there. Considering you are shifting emphasis toward software and services, are you still seeing demand from customers where they prefer you to do the procurement?
Arun Narayanan
I would characterize Stem as a trusted advisor. We have really good relationships with our customer and the ability for our technical expertise in the organization to assist customers through that journey is very valuable to our customers. So we have de emphasized the OEM hardware resale component of the business. But when we see opportunities to help customers meaningfully and it doesn't use up our balance sheet, we do pursue it. And this is how we see the year develop and that's how we are guiding to it.
Justin Claire
Okay. And then just one more on margins. Wondering if you could give us a sense for how you see the gross margins evolving for software services and Edge hardware in 26 relative to 25. It looks like you could potentially have a higher mix of battery hardware resale, which is lower margin. But overall for the year, it looks like margins could be flat year over year. So it implies there could be an expansion in the software margins. So just checking, is that the right interpretation and how we should think about it?
Brian Musfelt
Yeah. Hey, Justin, this is Brian. Yeah, I mean, we've guided you to 40 to 50% for the year. You know, that is obviously at a mix of kind of revenue, software services and hardware. We do break out for you now in our slide deck the kind of detail by each revenue kind of line. You can look at that appendix for that. But yeah, I think you see that this year software was over 70% or just north of 70%. So I think you can, you can look at that from a mixed perspective and based on our guidance and what we're looking at for improved software revenue will drive that mix up a bit.
Justin Claire
Gotcha. Okay. I appreciate it.
OPERATOR
Thank you. As a reminder, if you'd like to ask a question, please press star and the number one on your telephone keypad. We'll take another moment to poll for any questions. There are no further questions at this time. This concludes our question and answer session. I'd like to turn the call back over to Arun for closing comments.
Arun Narayanan
I want to thank everyone for joining our fourth quarter and full year earnings call and we look forward to speaking with you next during our first quarter 2026 earnings call Thanks everyone.
OPERATOR
Ladies and gentlemen, thank you for your participation. This concludes today's conference. Please disconnect your lines and have a wonderful day.
