Please go ahead, Jason.

Hello, everyone. Thank you for joining our earnings conference call for the fourth quarter and the full year of 2025. The fiscal year 2025 was a definitive transitional period for CBAK Energy, characterized by our comprehensive structural upgrade of our product portfolio, aggressive capacity expansion and deliberate pivot toward next-generation form factors. Despite the short-term bottom-line pressure inherent to some massive capacity transitions, our top line growth demonstrated positive momentum. In the fourth quarter, our consolidated net revenue surged by 131.80% year-over-year to $58.80 million. For the full year, consolidated net revenue reached $195.19 million, representing an 11% increase over 2024. Let me detail the structural transition driving our core business. At our Dalian facility, our customers are actively transitioning away from our legacy 26-series battery product line with over a decade of history and 1 gigawatt hour capacity to our newly introduced highly advanced Model 40135 cells. To support this paradigm shift, we successfully commissioned a new 40135 product line with 2.3 gigawatt hour capacity at the end of 2025. The market reception has been truly unprecedented. Demand for the 40135 cells currently far exceeds our available supply. Meaning, we are selling every single unit we can produce, and our order book heavily outpace our current ramp-up trajectory. Similarly, at our Nanjing facility, to alleviate the severe supply shortage for our highly sought after model 32140 cells, we successfully added 2 new production lines at our Phase II facility at the end of 2025. This expansion adds 3.0 gigawatt hour of much needed capacity to complement the 1.5 gigawatt hour already operational in Phase I. And we expect these 2 new high-speed lines to reach full capacity by early 2027. Both our Dalian and Nanjing expansion are currently in an intensive capacity ramp-up phase. While this initial phase carries…

Thank you, Jason. 2025 demonstrated the resilient dialectical nature of our vertically integrated business model. While our Battery segment faced margin compression due to the aggressive ramp-up of our new production lines and rising raw material costs, our Hitrans raw materials segment capitalized on this exact macroeconomic environment. Looking at our fourth quarter results. Consolidated net revenues reached $58.80 million, a 131.8% increase compared to Q4 2024. This hyper growth effectively decoupled from the temporary bottom line pressures caused by our ongoing capacity transactions. Within this, our Battery Business revenues were about $30.82 million, an increase of 35.8% year-over-year. Despite a 10.6% decrease in energy storage sector caused by the phaseout out of legacy Model 26650 cells at Dalian, we offset this decline through explosive growth in the LEV revenues, which skyrocketed by 524.2% to $12.92 million in the fourth quarter. Our Hitrans segment generated $27.98 million in Q4 2025, a massive 944.1% surge from Q4 2024, directly reflecting the escalating upward cycle of raw material pricing and robust downstream order placements. Our gross profit for Q4 2025 was about $4.28 million, representing a gross margin of 7.3% compared to 13.1% in Q4 2024. This sharp margin compression was fundamentally driven by the transactional friction costs, suboptimal yields and disproportionately high fixed cost absorption inherent to the initial ramp-up phase of the new Model 40135 in Dalian and Phase 2 Models 32140 lines in Nanjing. Consequently, operating loss for the fourth quarter was about $8.01 million, and the net loss attributable to shareholders was $7.38 million. For the full year 2025, net revenues were $195.19 million, up by about 11% year-over-year. Hitrans contributed $89.21 million, up by 123%, while the Battery Business contributed $105.98 million. Gross profit for the year was about $18.42 million, representing a margin of 9.4%, down…

[Operator Instructions] We will now take the first question, question is from the line of Brian Lantier from Zacks Small-Cap Research.

Fantastic news to see Hitrans suddenly turning things around. I wonder if you could talk a little bit about where you see gross margins in the Battery Business? And when you think they might normalize as you ramp up capacity?

Thank you, Brian. Let me answer your question. So I think it was back in Q3 and Q4 when our Nanjing Phase 2 and our Dalian operations and new products kick in, our gross margin was affected severely. So right now, we are in a phase of ramping up capacity. And we believe that the Dalian facility ramp-up would be completed in the first half of this year, which we have already received way enough orders for these new products. And for Nanjing Phase 2 because it's much bigger, so our time line is for early 2027, but we have confidence to try our best to catch up the time line. So our target would be also the second half of 2026, but the reasonable timetable will be early 2027. So ideally, in the second half of this year, our gross margin will gradually revolve. And I believe in the full year of 2026, the gross margin number at least looks better than right now.

Great. And could you describe a little bit more about the cell packing business? And do you see that becoming a growth opportunity for the company, particularly in the LEV market?

I will answer the question first and then, Yvonne, please help with the interpretation for Jason, and Jason I think can add some points. So we have received a substantial order from one of our major African customers who actually originally from India, and starting early 2025, this substantial order kick in and they use most -- I think all the cells purchase were from Nanjing 32140. And in order to do that, we have already set up a battery pack assembly unit within our structure, and this unit is dedicated to purchase cells from our Nanjing factory and put the cells into a battery pack and sell it to the African customer. And this customer has already become 1 of our top 5 customers as of 2025. And we are also looking forward to a much deeper and more comprehensive collaboration with each other. Maybe in the future, our collaboration will extend beyond the area of LEV into energy storage sector. So I think this is what I want to add. Please Jason, see if anything you want to add?

There's only 1 thing that Jason would like to add, which is the advantage of our battery cell use in the LEV market. So this has already been demonstrated in the Southeast Asia market and Indian market. So our product, no matter our cell or battery pack, are -- performs really well in high temperature. This is very critical to this kind of application. So we think we may meet the same success as we already did in the Southeast and Indian market.

Great. That's really helpful. I guess 1 final question. Are you seeing anything on the energy storage front as it relates to grid storage best companies? And is that impacting your R&D plans for new cell formats that could come out at the end of the decade?

I think that's a question for Jason.

[Foreign Language]

[Foreign Language]

So currently, for the ESS market, I think we are only focusing on the home ESS, balcony ESS and also portable ESS, so which are all like smaller size. But in addition, we are also in research and development of our big prismatic cell, which can be used in what you just mentioned, the grid size energy storage system. So that will be like one of our like target product for this.

[Operator Instructions] We will now take the next question, this is from the line of [ Charles Nemec ], Individual shareholder.

Now I've reviewed the 40135 ramp-up data and the margin compression. And I have a structural and validated solution for the thermal wall and charging limitations impacting you daily in production. Now I submitted a brief to your executive inbox, and I sent one to your engineer as well, and I'm just wanting to confirm that you've received that. And if we could make a time to discuss those matters in a private forum?

Which engineer or which e-mail address you contacted through?

The e-mail I sent it to is -- let me find it here, ir@cbak.com.cn.

Okay. There are just -- daily, there are thousands of e-mails coming in, so maybe in the junk box or maybe it just be in [ filtered ]. So can you just resend the e-mail and we'll make sure that related personnels would just look into it.

Okay. I can resend them all. I sent them on the 28th early in the morning, but I can resend them. There's one to the CEO, the second in command and your engineer, all of you got a copy through that e-mail and I tagged you call.

Okay. We will just review it.

Seeing no more questions in the queue, so let me turn the call back to Jason for closing remarks.

Thank you, operator, and thank you all for participating in today's call and for your support. We appreciate your interest and look forward to reporting to you again next quarter on our progress.

Thank you all again. This concludes the call. You may now disconnect.
