Good afternoon, everyone. Thank you for joining our earnings call. Despite the impact of the pandemic, geopolitical conflicts and the other extreme multifaceted uncertainties which have created unprecedented challenges for the overall semiconductor market, Hua Hong Semiconductor maintained a steady growth in the fourth quarter of 2022. Revenues reached $630.1 million, setting a new sales record for the 10th consecutive quarter and growing 90.3% year-over-year. Annual revenue for 2022 was $1.476 billion, an increase of 51.8% compared to 2021. The company focused our diversified specialty technology, continuing to upgrade technology and expand capacity to meet new market demands in a timely manner.
The company has continued to optimize its product mix, maintain high capacity utilization at all fabs, and obtain reasonable sales price increases, resulting in an improved gross margin of 38.2% in the fourth quarter, an increase of 5.7 percentage points year-over-year. Annual gross margin for 2022 reached 34.1%, up 6.4 percentage points from 2021. Return on equity also improved significantly, reaching 22% in the fourth quarter. Return on equity from 2022 reached 15.2%, up 5.5 percentage points from 2021. An excellent outstanding performance was achieved in 2022. I would like to sincerely thank all our employees and partners for their tireless efforts to this end.
Looking ahead to 2023, we will continue to strengthen our competitive edge in various specialty technologies and dynamically adjust our marketing strategies in line with market demand trends to better meet the needs of our domestic and international customers with more extensive and more competitive process solutions. In terms of capacity, we will continue to implement the strategy, including continuous optimization of the 8-inch platform, technology upgrade of the 12-inch platform and the 12-inch capacity ramp up. The Phase 1 of the 12-inch expansion has been fully completed, with the 12-inch production line operating at 65,000 wafers a month in 2022. All the equipment for the expansion Phase 2 is in place, and the capacity will be increased throughout 2023 to 95,000 wafers a month.
Work on the construction of a new fab will start in due course, continuing the progress of our differentiated specialty technology to more advanced nodes. The midpoint of an S-curve growth of revenue is the fastest growth rate with the most turbulence and challenges. When our employees must work harder and smarter for success, there will always be challenges as we grow our business, and we must persevere at these critical times. Hua Hong Semiconductor is well-prepared and confident to address our new opportunities and challenges in the new year. I would like to hand the call over to our CFO, Mr. Daniel Wang, for his comments.
Thank you, Mr. Tang, for your comments. Let me begin with a summary of our financial performance for the fourth quarter and the recap of the whole year 2022, followed by an outlook on revenue and margin for the first quarter 2023. We will move on to the question and answer session. First, let me summarize financial performance as of the fourth quarter. Revenue reached $630.1 million, up 19.3% year-over-year, and flat to the prior quarter. Gross margin rose to 38.2%, 5.7 percentage points higher than Q4 2021, primarily due to improved average selling price, partially offset by increased depreciation costs, and 1 percentage point above Q3 2022, primarily due to improved average selling price.
Operating expenses were $59.6 million, 87% over Q4 2021, primarily due to decreased government grants for research and development, and 19.1% below Q4 2022, mainly due to increased government grants for research and development. Other income net was $35.6 million, 27.9% over Q4 2021, primarily due to increased interest income and share of profit of associates, partially offset by increased finance costs. There was an other loss net of $57.8 million in Q3 2022, mainly due to large foreign exchange losses. Income tax expenses was $30.9 million, 2.3% above Q4 2021.
Profit for the period was $185.8 million, 35.4% above Q4 2021, and 183.9% over Q3 2022. Net profit attributable to shareholders of the parent company was $159.1 million, 19.2% above Q4 2021, and 53.2% over Q3 2022. Basic earnings per share was $0.122, 18.4% above Q4 2021, and 52.5% over Q3 2022. Annualized ROE was 22%, 2.8 percentage points higher than Q4 2021, and 7.6 percentage points above Q3 2022. Now, I will provide more details on our revenue from Q4 2021.
From geographical perspective, revenue from China was $456.9 million, contributing 72.6% of total revenue, and an increase of 14.5% over Q4 2021, mainly due to increased demand for MCU, IGBT, super junction, and smart car ICs, partially offset by decreased demand for logic products. Revenue from North America was $86 million, an increase of 60.6% over Q4 2021, mainly due to increased demand for MCU products. Revenue from Asia was $42.1 million, a decrease of 16.7% compared to Q4 2021, mainly due to decreased demand for discrete and logic products. Revenue from Europe was $33.7 million, an increase of 81% over Q4 2021, mainly due to increased demand for smart car ICs, general MOSFET, and IGBT products.
Revenue from Japan was $11.5 million, an increase of 7.1% over Q4 2021, mainly due to increased demand for MCU products. With respect to technology platforms. Revenue from embedded nonvolatile memory was $236.3 million, an increase of 75.7% over Q4 2021, mainly due to increased demand for MCU and smart car ICs. Revenue from stand-alone nonvolatile memory was $36.6 million, a decrease of 6.3% over Q4 2021, primarily due to decreased demand for NOR flash products. Revenue from discrete was $213 million, an increase of 21.3% over Q4 2021, mainly due to increased demand for IGBT and super junction products.
Revenue from logic and RF was $42.9 million, a decrease of 49.5% compared to Q4 2021, mainly due to decreased demand for CIS and logic products. Revenue from analog and power management IC was $100.9 million, an increase of 7.8% over Q4 2021, mainly due to increased demand for other power management IC products. Let's now take a look at the cash flow statement. Net cash flows generated from operating activities was $184.4 million in Q4 2022, 10.8% below Q4 2021, primarily due to increased payments for materials and maintenance, partially offset by increased revenue.
Capital expenditures were $331.1 million in Q4 2022, including $310.9 million for the 12-inch fab and $20.2 million for the three 8-inch fabs. Other cash flow generated from investing activities was $27.9 million in Q4 2022, including $24.7 million of receipts of government grants for equipment and $7.3 million of interest income, partially offset by $4 million of investment in associate.
Net cash flows generated from financing activities was $120.1 million in Q4 2022, including $181.5 million proceeds from bank borrowings, $11.1 million of receipts of government grants for finance costs, and $1.6 million proceeds from share option exercises, partially offset by $30.8 million of bank principal payment, $32 million of interest payments, $0.8 million of listing fee, $0.8 million of restricted deposits, and $0.7 million of lease payments. Now, let's move to the balance sheet. Cash and cash equivalents was $2,008.8 million on December 31st, 2022, compared to $1,984.2 million on September 30th, 2022.
Inventories increased from $509.6 million on September 30th, 2022, to $575.4 million on December 31st, 2022, primarily due to increased manufacturing supplies against potential pandemic risk. Property, plants, and equipment was $3,367.7 million on December 31st, 2022, compared to $3,140.2 million on September 30th, 2022. Total assets increased from $6,660.4 million on September 30th, 2022, to $7,052.7 million on December 31st, 2022. Our total bank borrowings increased to $1,908.3 million on December 31st, 2022, from $1,778 million on September 30th, 2022.
Total liabilities increased to $2,800.8 million on December 31st, 2022, from $2,917.2 million on September 30th, 2022, primarily due to increased bank borrowings. Debt ratio decreased to 41.4% on December 31st, 2022, from 42.1% on September 30th, 2022. I would like to give you a recap of our performance for the entire year of 2022. Revenue was $2,475.5 million, an all-time high and an increase of 51.8% over the prior year. Gross margin was 34.1percentSix point four percentage points over 2021, mainly due to improved average selling price and product mix, partially offset by increased depreciation costs.
Operating expenses were $279.1 million, 33.2% over 2021, largely due to decreased government grants for research and development and increased labor expenses. Other loss net was $68.5 million versus other income net of $54.3 million in 2021, primarily due to foreign exchange losses versus foreign exchange gains in the prior year. Net profit was $406.6 million, 76% over 2021. Net profit attributable to shareholders of the parent company was $449.9 million, 72.1% over 2021. Basic earnings per share was $0.345, 71.6% over 2021. ROE was 15.2%, 5.5 percentage points over 2021.
Finally, let me give you a high-level outlook for the first quarter 2023. We expect revenue to be approximately $630 million, and our gross margin between 32% and 34%. This concludes my financial remarks. Now we would like to start the question and answer session. Operator, please assist. Thank you.
Thank you. To ask a question, you'll need to press star one and one on your telephone and wait for your name to be announced. To withdraw your question, you can press star one and one again. That's star one one for any questions. Thank you. We'll now take our first question. Please stand by. This is from the line of Randy Abrams from Credit Suisse. Please go ahead.
Okay. Yes, thank you. A good result. I wanted to ask actually on outlook for first quarter holding quite firm relative to your peers. If you could go into some of the areas by application continuing to hold up and just in terms of the industry weakness, I'm curious if you expect moving through coming quarters, enough strength from these applications to stay resilient, like to continue to put up this type of outperformance relative to peers, or you see potential, a delayed correction that may eventually start to impact your business?
Thank you, Randy. Very good question. I think with Q1 is gonna be a very stable quarter, okay. I think our company will continue to thrive. We expect overall, we're gonna be flat compared to Q4. normally Q1 is always a low year, a low quarter. We continue to believe that we we're gonna hold $630 million for the quarter, okay. We expect some of the areas continue to be very, very strong. Smart car ICs will continue to grow. MCU will continue to do well, I think most likely will be flat.
Discrete overall will grow again, probably a very good digit, double-digit growth, expect particularly for IGBT and super junction and the medium voltage products, okay. Also, stand-alone nonvolatile memory, I think we'll continue to have a nice growth on that. Overall, I think we're gonna have a very good quarter. I think the product mix will get better. I think our ASP will continue to hold well for Q1. , I mean, we expect, we're we're very confident with the entire year 2023, okay. There are gonna be some challenges, but I think just in general, I think it's gonna be we think just overall it's gonna be a good year for us.
Okay. Thanks. Thanks, Daniel. The follow-up to that, just on the margin, because you mentioned, like, the improving mix. Just for first quarter, I know you usually leave a little bit of conservatism, but for the Q1 decline. Maybe talk about the factors, whether it's pricing or depreciation, like or seasonal factors like maintenance, but just if you could go into the factors influencing the first quarter lower margin. Do you think through the year it stays a bit lower or it comes back up to the recent, like, very good margin performance?
Yeah. , Randy, it's, I already mentioned I think overall ASP will hold well throughout Q1. I think overall, in general, Q1 is a low quarter, as I mentioned. It's largely because of the margin is gonna be slightly lower than Q4. It's largely because just gonna be additional depreciation expenses coming out of the capacity expansion from the 12-inch fab and also the additional costs just in general facility costs. Secondly, we did annual maintenance for fab one to fab three, the two 8-inch fabs. each the impact is about five days for each fab. The fixed costs certainly will have an impact on the gross margin.
I think approximately it's about 2 percentage points on the margin. also we accrued some annual bonus that would be basically coming out into the cost of goods sold in Q1. The impact is also gonna be about 2 percentage points. These are the points I think will impact the overall margin. That's why we said the margin is gonna be between 32% and 34%. , the company will continue to try our best to make sure that we will do better.
Okay. No, thanks for that helpful color on that. It sounds like those, a few of those points are only first quarter impact, the annual bonus and the maintenance. For the expansion of the 12-inch, the additional 30K. Maybe, two questions to it. How quickly does that capacity come on? Do you see, as far as, like, filling it, like for shipments through the year for the additional 30K? Then if you could give a view this time implication for this year CapEx and depreciation, like if you have a guidance for 2023 for those?
Yeah. Very, very good question. We expect the we add 30,000 wafers in 2022. This additional 30K will basically start to be released. The 30,000 wafers will start to be released into the operations this year. We expect by in a sort of gradual fashion, I thought by end of this year we're gonna get to Q3 or Q4, the wafer load will get to about 95,000 wafers.
Okay. Do you have the-?
When you talk about the depreciation expenses for the 12-inch fab I would say, last year it was about $325 million. We expect this number would go up. I think but we we're gonna manage that number, huh. It's probably gonna get close to $400 million for the year. Okay? We're gonna, you'll see a gradual increase on depreciation costs throughout the quarters. Randy?
Randy, are you still on the line?
Randy, your line is still open. Shall we move on to the next question?
Yeah. Maybe we move on the next question. If Randy come back, we can ask his question again.
Sure. Thank you. We'll take our next question. Please stand by. This is from the line of Szeho Ng from China Renaissance. Please go ahead.
Oh, hi, gentlemen. Congratulations on a great result. Two questions from my side. First one, regarding the next new fab in Wuxi. When would we start having some capacity coming on board?
Szeho, you're talking about the second fab?
Right.
Okay. The plan is to start the construction hopefully soon, sometime this year, definitely within the H1 of this year, 2023. It would normally take about a year to build the fab. We expect as soon as the fab is complete, construction fab is complete, we're gonna start the production ramp up. It'd be sometime H2 next year, I would think, imagine, expect.
I see. I see. Right. Upon a full completion, a portion of the fab will be allocated for 40 by 40 nano production, right? Correct me if I'm wrong.
Yeah, it's gonna be the fab will be between 40 and 55, and some part discrete, like IGBT and super junction.
I see. for 40-45, it won't be a huge portion, right?
Will be what? Sorry.
Will not be a huge portion for the 40/45 nano.
Well, I would think for the next fab, it's gonna be as far as technology nodes, it's gonna be between 55 and 40.
Ah.
Even, evenly.
Okay. I see. Second question on the OpEx side. For this year, we should expect the operating expense to be kept linear, I think, across the four quarters.
Well, yeah we have to. , I think just overall, the cap expenditures will be for Shanghai, it'll be around $200 million the most. Okay? That's the budget. I don't think we're even going to go that far. Probably it's gonna be $100 million. For Wuxi, is just to the construction of the fab, it's gonna be around $500 million.
I see. Okay. Right. Okay. Okay. All right.
Yeah. , this is gonna something we're gonna have to spend this year. As far as the tools, well, most likely, expenditures for the tools will happen next year.
Oh, okay. Okay. All right. Yeah. Actually, my question is on the operating expense side, maybe you can also elaborate on that part. Yeah.
For the second part?
Operating expense, yeah. Can we assume it's kind of steady and something like $70 million-$75 million a quarter?
For which? For overall or?
For overall. Overall, yeah. This year.
Oh, for overall. Wuxi or including the 8-inch operations?
I think for the group maybe, including both 8-inch and 12-inch.
Okay.
Just for model.
, it's about. Yeah, you're right. It's around $70 million a quarter overall.
Okay. All right.
It's. Yeah. , that was for 2022. I think overall the operating expenses should be pretty stable throughout 2023.
Okay. I got you. Yeah. Thank you. Thanks very much. Congratulations again.
Thank you. Thank you.
Thank you. We'll now take our next question. Please stand by. This is from the line of Leping Huang from Huatai. Please go ahead.
Okay. Thank you for taking my question. Congratulations for the very good results. From the page 9 of your presentation materials, we see a very big change of your product mix. I just want to clarify. First that whether the IC capacity and the power discrete capacity is not interchangeable. If my understanding correct, can you explain, since the IC side, overall industrial demand is very weak, how you... What's the magic you do that you maintain such a high utilization rate and what are the new application which fill the capacity? Thanks for your question. As for our capacity allocation, we always focus on our 5 major technology platforms.
From the feedback of the H2 last year, our marketing feedback of our all 5 technology platforms are very good. Especially our traditional technology platforms with privileges, like HV IGBT, MCU Flash, are well received, especially by our customers. Thanks to the growth of new energy vehicles, green energies and solar energies, they all support our stable growth of business. In terms of the capacity synergy, the original plan and our actual results are very good. Thank you. The 2nd question is about your CapEx budget this year. I did not see you put a number on your presentation material. Also related question is theWe see the total capacity of your wafer remains flat since the 1st quarter last year.
When you expand the capacity, what are the reasons behind? I think, are there any difficulty to introduce the equipment and what's your schedule to put the equipment that near 30,000 wafer capacity this year?
Thank you for your paying attention to our work. Our capacity for the past year is about 65,000-70,000. There are some reasons. One is pandemic impact and also the delay of the tools. As for now, we have already installed about 80% or 90% of the tools of 95K. All the moving will be complete about by the early H3 of this year. Third quarter this year, sorry. The overall 30K capacity will be released gradually from the second quarter to the end of the year. It's a gradually process.
Oh, sure. Thank you.
Thank you. As a reminder, if you would like to ask a question, please press star one and one on your telephone and wait for your name to be announced. That's star one one if you would like to ask a question. There are no further questions at this time, so I'd now hand back to the speakers.
I think, again, I want to thank you all for joining us today and asking all the good questions. We hope you will join us again sometime in the future, next quarter. Please continue to stay safe and healthy. We look forward to meeting you in person very soon. Thank you.
Thank you. Ladies and gentlemen, thank you for your attendance. You may now disconnect.
