TYGO

Good afternoon. Welcome to Tigo Energy's fiscal first quarter 2026 earnings conference call. At this time, all participants are in listen-only mode. After the speaker's presentation, there will be a question and answer session. Joining us today, Tigo are Zvi Alon, CEO, and Bill Roeschlein, CFO. As a reminder, this call is being recorded. I would now like to turn the call over to Bill Roeschlein, Chief Financial Officer.

Thank you, operator, and it's a pleasure to join you today from our corporate offices in Los Gatos, California. Also with us is Zvi Alon, our CEO.

We'd like to remind everyone that some of the matters we'll discuss on this call, including our expected business outlook, our ability to increase our revenues and our overall long-term growth prospects, expectations regarding a recovery in our industry, including the timing thereof, statements about demand for our products, our competitive position and market share, the impact of tariffs, our current and future inventory levels, charges and reserves, and their impact on future financial results, inventory supply and its impact on our customer shipments, statements about our revenue and adjusted EBITDA and non-GAAP net loss for the second fiscal quarter 2026, and our revenue for the full fiscal year 2026, our ability to penetrate new markets and expand our market share, including expansion in international markets and investments in our product portfolio.

We're all forward-looking statements, and as such, are subject to known and unknown risks and uncertainties, including but not limited to those factors described in today's press release and discussed in the Risk Factors section of our most recent annual report on Form 10-K, our quarterly report on Form 10-Q for the fiscal quarter ended March 31st, 2026, and other reports we may file with the SEC from time to time. These risks and uncertainties may cause actual results to differ materially from those expressed on this call. Those forward-looking statements are made only as of the date when made. During our call today, we will reference certain non-GAAP financial measures. We include GAAP, non-GAAP to GAAP reconciliations in our press release furnished as an exhibit to our Form 8-K.

The non-GAAP financial measures should not be considered as a substitute for or superior to the measures of financial performance prepared in accordance with GAAP. Finally, I'd like to remind everyone that this conference call is being webcast, and a recording will be made available for replay on Tigo's investor relations website at investors.tigoenergy.com. With that, I'd like to now turn the call over to Tigo CEO, Zvi Alon. Zvi?

Thank you, Bill. To begin today's discussion, I will highlight key areas in our recent financial and operational performance before turning the call over to our CFO, Bill. He will discuss our financial results for the first quarter in more depth, as well as provide our guidance for the second quarter of 2026 and full year of 2026. After that, I will share some closing remarks, tell you about the outlook, and then open the call for questions from the analysts. Business update. We delivered a strong start to 2026, despite the typical weather-related seasonality in our end markets. To be more specific, in the first quarter of 2026, we reported a total revenue of $25.2 million, representing a 33.7% increase compared to the first quarter of 2025.

By geography, we saw seasonally stronger performance on a year-over-year basis with the EMEA region during the quarter, which comprised 69.5% of our revenue. Recently, we also announced that our enhanced Tigo GO Battery is now available in the European residential market and is expected to further strengthen our European presence with storage capacity up to 47.9 kilowatt hours and integrated heating for cold weather operations. Within Americas region, which comprised 20.9% of our revenue, we saw higher performance on a year-over-year basis, but lower results quarterly as the buyers accelerated purchases late last year ahead of the expiration of Residential Clean Energy tax credit. By country, we performed exceptionally well in Italy, which grew 140.8% sequentially, and again in APAC, in Australia, which grew 64.3% compared to Q4.

I would also like to highlight strong growth in the Czech Republic and Poland, where an unusually cold weather patterns during Q4 had significantly impacted solar installations, as mentioned in our last earnings call. These results were offset by seasonal softness in Germany and weaker results in the U.K. market, where vast growth in 2025 moderated for us in the current quarter. As we look at the energy sector as a whole, energy security is an increasingly important priority for governments, businesses, and homeowners across the globe. The recent geopolitical developments in Iran continue to highlight importance of energy independence worldwide. As energy markets remain volatile, we believe Tigo is well-positioned to support installers, homeowners, and commercial customers seeking flexible, reliable, and intelligent solar and storage solutions.

Finally, as we look forward or towards the rest of the year, I would like to share three specific growth catalysts that I expect will drive accelerated growth for Tigo. First is our partnership with EG4, which is just now beginning to kick off with the first deliveries occurring this month. This partnership is expected to provide the U.S. market with an Section 45X and Section 48E ITC credit-qualified optimized inverter solutions. Second, in our new line of Tigo GO ESS batteries for the U.S. and EMEA markets, this provides a compelling and complete solution for TPOs in the U.S. and addresses market requirements for additional storage capacity in EMEA region. Third is the positive activity we are seeing in our pipeline for large-scale utility deals, where we believe as a competitive advantage. With that, I would like to turn it over to Bill. Bill?

Thank you, Zvi. Turning now to our financial results for the first quarter ended March 31st, 2026. Revenue for the first quarter of 2026 increased 33.7% to $25.2 million from $18.8 million in the prior year period. On a sequential basis, revenues decreased 16.1%, despite improved results coming from many countries in the EMEA region, including the Czech Republic, Italy, and Spain. By region, EMEA revenue was $17.5 million, or 69.5% of total revenues, and a 3.2% sequential decrease. Americas revenue was $5.3 million, or a 20.9% of total revenues, and a 43% sequential decrease. APAC revenue was $2.4 million, or 9.6% of total revenues, and a 10.2% sequential decrease.

By product family, for the first quarter of 2026, MLPE revenue represented $20.8 million of revenue or 82.4% of total revenues. Go ESS represented $4 million or 15.8% of total revenues. Predict+ represented $0.5 million or 1.8% of total revenues during the quarter. Gross profit for the first quarter of 2026 was $10.8 million or 42.8% of revenue, compared to a gross profit of $7.2 million or 38.1% of revenue in the comparable year-ago period. Improvement in gross margin is largely due to the absence of warranty-related charges in the most recent quarter compared to the year-ago period.

Operating expenses for the first quarter increased 18.4% to $13.2 million compared to $11.2 million in the prior year period. The increase was driven primarily by bad debt expense of $1 million as a result of the bankruptcy of a European distributor during the quarter. We do expect a portion of this amount to be recoverable through insurance in a future period. Operating loss for the first quarter decreased by 19.4% to $4 million compared to operating loss of $4 million in the prior year period. GAAP net loss for the first quarter was $1.8 million compared to a net loss of $7 million for the prior year period.

Non-GAAP net loss, which we are introducing this quarter and reconciles from GAAP net loss solely by excluding stock-based compensation, totaled $0.1 million compared to a non-GAAP net loss of $5.4 million in the prior year period. We believe this measure provides investors with additional insight into our progress toward achieving consistent GAAP net income. Adjusted EBITDA loss for the first quarter decreased 76.8% to $0.5 million, compared to an Adjusted EBITDA loss of $2 million in the prior year period. As a reminder, Adjusted EBITDA is a non-GAAP measure that represents net loss as adjusted for interest and other expenses, income tax expense, depreciation, amortization, stock-based compensation, and M&A transaction expenses. Primary shares outstanding at the end of the quarter were 75.9 million.

Turning to the balance sheet, accounts receivable net increased this quarter to $14.2 million compared to $13.9 million last quarter and increased from $10.4 million in the year-ago comparable period. Inventories net decreased by $6.5 million or 20.7% to $24.8 million compared to $31.3 million last quarter and increased compared to $18.9 million in the year-ago comparable period. Cash, cash equivalents, and short and long-term marketable securities totaled $11.6 million at March 31, 2026. On a sequential basis, cash increased by $3.9 million as we successfully closed a registered direct offering of approximately $15 million during the quarter. In addition, we closed on a credit facility with Wells Fargo Bank at the end of the first quarter.

The facility provides up to $10 million of availability based upon a borrowing base formula consisting of certain accounts receivable and inventory held by the company. No drawdowns were taken during the first quarter. Turning now to our financial outlook for the second quarter of 2026 and full year of 2026. As a reminder, Tigo provides quarterly guidance for revenue as well as adjusted EBITDA, as we believe these metrics are key indicators for the overall performance of our business. For the second quarter of 2026, we expect revenues and adjusted EBITDA to be in the following range. We expect revenues in the second quarter ended June 30th, 2026 to range between $30 million and $32 million. We expect adjusted EBITDA to range between $1 million and $3 million.

For the full year of 2026, we continue to expect revenues to range between $130 million and $135 million. That completes my summary, I'd like to now turn the call back over to Zvi for final remarks. Zvi?

Thanks, Bill. We are pleased with how we have started 2026 and the traction we are seeing across our key markets. The continued predictability of our business reinforces our confidence in sustaining growth through the remainder of the year, and we expect to maintain our competitive outperformance. We enter the remainder of the year with a strong foundation and a clear path to follow, and we're excited about the opportunities ahead. With that, operator, please open the call for Q&A.

Thank you. At this time, we will conduct the question and answer session. As a reminder, to ask a question, you will need to press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. Please stand by while we compile the speaker roster. Our first question comes from the line of Philip Shen with ROTH Capital Partners. Philip, your line is live.

Hi, thanks for taking my questions. wanted to start with the potential for the EU to ban Chinese inverters and wanted to understand if you could be a beneficiary of that. What have you learned about this, and how quickly could this ban become effective? It seems like it could be or may be effective already. Are you seeing a change in the business at all already? Thanks.

We are aware of the change. It actually started, I would say probably last year sometime, and there are 2 countries already that are banning Chinese-controlled monitoring systems and devices. We do believe that it would actually increase the market share for our solutions out there. We see it as a positive contributor for our solutions in the market. We have been touting the security of us being the U.S., the monitoring in the U.S., solutions for quite some time, and that seems to be obviously working with those sentiments which are in the market in general.

Okay. Thanks, Zvi. Are you seeing a change in demand for your business because of this, or is it hard to discern that the demand is coming from this?

Yes. Right now, it is hard to actually say that it is correlated. In general, I can tell you that we have seen Europe starting to wake up towards the end of the quarter, the first quarter. From that perspective, we are fairly confident it will continue, and that addition of the banning of Chinese will just accelerate it and help more. I can tell you that our optimizers are doing exceptionally well in the market.

Great. Thanks, Zvi. Can you elaborate more on that? I know, you know, you had a lot of volume, most of it from Europe in the quarter. That mix of, you know, call it, 70% from EMEA or Europe. Do you think that mix stays similar through the rest of this year? Maybe give us a little more color on which countries are strong and maybe which countries have been less strong but could become stronger ahead.

We've been sort of trending in these percentages for a little bit of time here, about 65%-70% from EMEA. It was once higher than that. The U.S. has really picked up steam for us and with the Repowering that we've had and now with the introduction of our new hybrid inverter and battery solution, along with EG4 partnership for optimized inverters, we think that Europe, the U.S. could be a market where we pick up a good share regardless of the macro condition there. That might drive the EMEA region perhaps to be a little bit less than 7% by the time we get to the end of the year.

We'll just have to see how that plays out. Within the European area, we've historically been strong in Italy, Germany, those being the two biggest economies last year with the U.K. Germany has been by most accounts big but sluggish. I'd say we've had decent growth, but the areas where we've seen some really outsized growth that's really working in our favor, and I think it's gonna work out this way in 2026 as well, is the U.K. was really great because we came in with almost 0 market share and just quickly established a good revenue base coming into that country.

In 2026, we're making a concerted effort to go after more of the Eastern European theater, where we talked about them this call before, some competitors have withdrawn a bit or reduced their footprint. That's where Slovenia, Romania, Poland, even the Czech Republic, which again, we've been doing strong for a while now, but there's still additional market share to be picked up there. We're sort of, like, expanding beyond our traditional strength in Italy, Germany, and going a little bit more east and north, if you will.

Great. Thanks, Bill. You mentioned Repowering. Can you give us some sense of how the success that you're having there? It sounds like, you know, this is a big opportunity. If you can quantify anything in terms of how much of your total revenue or total U.S. revenue that could be for 2026, that could be very helpful.

Sure. It more than doubled. It was about, you know, 23% of Section 25D. Most recently, it was 20%. Again, Zvi mentioned, we believe we had some pull-in orders related to the Section 25D expiration that kind of muddled the overall measurement of that. We're still working with the same installers, who have a brisk book of business. We again expect another year of growth coming from that side of the house. We have a very unique hybrid inverter that, you know, fits nicely.

It's got the right form factor, and it's got the right ability to accept varying voltage levels and minimal amount of wiring, rewiring required. There's just a lot of advantages to our solution that fits in well with Repower. Really, I think you're gonna now layer in our initiative with our GO ESS battery hybrid inverter for the year, along with EG4, and I think the U.S. market could be very, very strong growth for us this year.

Actually, on the Repowering, one additional point is that the more those systems age, the better it is for us. We've identified this market early, and we've been playing in it for quite some time and gaining quite nice momentum. As it ages, it should be better for us.

Great. Okay. Last one for me. That sounds exciting. Let's move over to the utility scale solar opportunity. Zvi, you mentioned that there's a large pipeline of opportunity there. I'm guessing this is tied to Predict+, which is a software package that you guys have. Was wondering if this is also tied to your optimizer opportunity. Just give us a little more color on what that looks like and how that could drive 2026.

Yes, I did mention last time that we see an increase in activity in utility scale, and that continues. I don't want to make any pre-announcements, which is not the right thing to do, but in general, we do see a momentum in both the Predict+ as well as the optimization. On the optimization, I would add that we see two main drivers. One is obviously new installations, and we did mention the large installation in Spain, which is now operational, up and running, right next to the Madrid Airport, which we got late last year. It was 142 megawatts. We see in the pipeline similar sized projects and number of them. We are fairly excited about it and optimistic.

Great. Thank you very much. I'll pass it on.

Thank you.

Thank you. Our next question comes from Eric Craig-Hallum Capital Group. Eric, your line is live.

Hi, Zvi. Hi, Bill.

Hi.

Hi.

Hey. I know you talked about the EU, the outlook here in 2026, but it was kind of more from a strategic point of view. I'm wondering if you can just dig in a little bit on the market improvement. You know, people starting to talk about green shoots. You mentioned that you saw that towards the end of the quarter. I mean, where does that stand? I know that you mentioned, at least in Q1, some softness in Germany and the U.K., and those are two countries where, you know, you are starting to see indications of that improvement. When do you anticipate you might start to see the benefit from that? You know, is it Q2? It seems like that type of expectation is not necessarily part of your outlook.

You know, when might you see it, and when do you become convinced that it is something that is sustainable market improvement?

Thanks, Eric. So we started seeing an improvement in the second part of Q1. The first part of Q1 was very sleepy, to be honest, which is fine. That's normal. It's not like it was different. Despite the fact, we still have seen a 30% growth quarter-over-quarter, year-over-year. I believe that Q2, by the guidance we provided, is also demonstrating a nice growth year-over-year, and obviously, it is based on some of the confidence we see in all regions, including Europe, which is the largest region we have. From our perspective, we do believe that we will continue to see market share gain. Also, Bill mentioned that we expanded into Eastern Europe in some places where our competitors have left, and we've seen some fairly good momentum.

Europe for us is actually showing some fairly good signs despite the fact that Germany was a little bit slow. I will highlight that we have seen Germany starting to get back to life at the 2nd half of Q1, the same as what I've highlighted for Q1. We are not quite sure they will get back to the same full strength of last year or more, but we have seen an improvement there, which is causing us to feel a bit more optimistic. In addition, my mention on the success in the utility scale projects, a good portion of them are in Europe. We don't wanna get into specificity right now, but this is a new area for us, which is based on the success in Spain we had and some new opportunities we've identified.

We believe fairly strong that Europe is going to be a very good place for us going, moving forward.

Yep. Okay. That is helpful. I guess maybe sticking with utility scale, you know, I know that you have talked about several times, you've got a number of opportunities. You've set the guidance in a spot that you believe is a good place to be. It's obviously very good growth. You've also talked about these opportunities, whether it's GO ESS, EG4, that would mean potentially significant growth in 2026. I'm curious, I mean, where would you put utility scale in that? Is that something that you're starting to see good signs, but that's more of a 2027 event, where it really starts to impact financials? Or is it something that potentially, depending on timing, could be more of a 2026 event?

Let me categorically be very clear. The increase in utility footprint is in 2026, and not the end of the year, and I will just leave it there.

Okay.

It Yeah.

Okay.

I would just add that we're, we don't normally talk about pipeline, but the deals that we're working on are getting to the point where they are, you know, ripe for a decision. There's enough of those in our pipeline where we are at least finalists where we feel confident that we'll have something to talk about this year.

Yeah.

You have been following us for quite some time, so we generally are more conservative. We don't share unless our confidence is high.

Yep. That's why I'm asking. I mean, I would just assume we should put this in the category along with those others that could mean upside to kind of what your view is, now. Okay. Maybe last one for me. This is just more a clarification on the Repowering. I know that the primary focus there is on the inverter side, but is that also something that potentially develops from an optimizer side as well as some of these older systems as they upgrade and perhaps they decide, you know, they're 10 years old and decide that they want, you know, that control at the panel level?

It's an outstanding question, Eric. You just hit, you know, the nail on the head. It actually gives us an access to two potential expansions. One is the optimizer, as you described it, and the second one is all the solutions we provide with a hybrid inverter, adding a battery is very cost-effective. By virtue of increasing that market share with our solutions in the Repower, it will give us an opportunity to sell additional batteries as well at a very cost-effective way compared to any other solution.

Okay. Thank you.

Very welcome. Thank you.

Thank you. Our next question comes from the line of Sameer Joshi with H.C. Wainwright. Sameer, your line is open.

Thanks. Thanks for taking my questions. A lot of our topics have been covered, but I don't think we discussed enough the GO ESS opportunity and traction. It seems that, with $4 million in revenues, it is sort of high since 2023. Are you looking at the meaningful contribution from GO ESS during 2026, and is it a contributor to growth?

We believe that with our next generation that we have here, we expect that it will be widely accepted by the market and the feature functionality, price point, et cetera, and size all line up to what customers are asking for. In both in the U.S., with new sales, TPO opportunities, and even Repowering, which is a captive market for us to get battery revenue from. In Europe, we have gone or we've addressed the market's desire for a larger storage capacity for both three-phase and single-phase markets, especially in the three-phase market.

Our new generation of battery has both the cold weather functionality, which is important in that market, and ability expansion, ability up to almost 48 kWh. That's what the market's been asking for, and that's why we're excited about being able to introduce it now. We expect 2026 to be, we expect to gain a lot of positive momentum out of both markets. Yes.

Understood. Thanks for that color. The second question is, inventory was down quarter-over-quarter sequentially, $6.5 million down. Should we read anything into this? Part two of that question is, how is the supply chain and how quickly can you rebuild this inventory? Especially given traction or projections for second or outlook for second half, as well as the hinted progress on utility scale.

We're still in, you know, an 8-week factory to customer supply chain environment, so we're not seeing major hurdles there. We as a corporate metric, we try to keep 90 to 100 days of inventory. We were trending higher than that, us bringing it down was just part of us trying to again, run the working capital at an optimal level for us. We'll continue to do it that way. You know, we have no problem meeting the utility, any big utility win. The benefit of having an outsourced contract manufacturing business model allows you to scale up and down very quickly, it's not very difficult to do. We've got the floor space to do it.

We can add another line if and when we need to.

Understood. Thanks for that. The last one, just a quick one. On operating expenses through the year, should we expect to see any marginal increases, or you have enough manpower and resources, so that we won't see any meaningful increase in OpEx?

I think we're trending in that $12.5 million to $13 million range for the rest of the year. If I were to put a wider lens on it, you know, $12.5 million-$13.5 million, so midpoint 13, somewhere in there. We are able to grow this year without having to add a lot of OpEx, demonstrating the leverageability in our operating model. We've been at this level around $13 million for several quarters now, I think that's the right ballpark for it for the rest of the year.

Got it. Thank you. Thanks for taking my questions.

Thank you.

Thank you. At this time, this concludes our question and answer session. I'd now like to turn the call back over to Mr. Alon for closing remarks.

Thanks again, everyone, for joining us today. I especially want to thank our dedicated employees for their ongoing contributions, as well as our customers and partners for their continued hard work. I also want to thank our investors for their continued support. Operator?

Thank you for joining us today for Tigo's first quarter 2026 earnings conference call.
