Thank you, Gavin. Good morning, and good evening, everyone. Before we start the detailed discussion of our first quarter performance, please note that, as Gavin just mentioned, we have enhanced our disclosures with more detailed operational and financial metrics starting this quarter. We believe these new metrics will provide shareholders with greater insight into our business.
Specifically, beginning in the first quarter of 2024, our IDC business was subdivided into wholesale IDC business and the retail IDC business based on the nature and scale of our data center projects. Prior to 2024, the subdivision was based on the types of customer contracts. You may find a detailed list of all wholesale projects in our IR presentation for this quarter. Accordingly, for operating metrics, we have presented them by retail and wholesale separately.
For the wholesale business, the metrics are mirrored in terms of power capacity instead of cabinets, which we believe will more meaningfully reflect our business development. In additional, our wholesale capacity is present across 3 different states, including in service and their construction and held for future development which we believe will provide a clear and more comprehensive picture of our wholesale capacity, boosting the high-growth potential of our wholesale business. For financial metrics, we have subdivided our net revenue into revenues from IDC business, which includes retail revenues and wholesale revenues and revenue from non-IDC business, which consists of our cloud and VPN business.
Now let's move on to our first quarter results. Please also note that, unless otherwise stated, all the financials we present today are for the first quarter of 2024 and are in renminbi terms. Furthermore, all the growth rates and revenue are on a year-over-year basis. We kick off 2024 with solid operating and financial results.
Our wholesale IDC business continued to gain momentum, driven by rapid customer movements. Capacity in service was 332 megawatts as of the end of first quarter. Capacity utilized by customers increased by 17 megawatts to 236 megawatts in the first quarter, primarily driven by increased demand for the customer in N-OR06, N-HB03 and E-JS03 data center.
As a result, the utilization rate of wholesale capacity improved to the 71% with the utilization rate for mature capacity reaching around 95% and the ramp-up capacity reaching around 34%. In addition, the capacity under construction was 139 megawatts with pre-commitment rate of around 75% and the capacity health for future development was 557 megawatts.
For our retail business, capacity in service was around 52,000 cabinets remaining flat compared to last quarter, with utilization rates stable at 64% and with the utilization rate for mature capacity reaching around 73%. MRR for retail cabinets was CNY 8,742 in the first quarter compared to CNY 8,759 for last quarter and CNY 8,874 for the same period last year.
Moving on our financial performance. We remain the focus on high-quality revenue business, and our efforts continue to generate positive outcomes, our net revenue increased by 5.1% to CNY 1.9 billion, mainly driven by the continued growth of our core business.
To highlight, our wholesale revenue increased by 59.1% to CNY 361 million, mainly contributed by E-JS Campus 01 Phase 1, and E-JS Campus 02, E-JS Campus 02 B, N-HB03 and E-JS03 data centers. On the other hand, retail revenue decreased by 7.1% to CNY 923.7 million, mainly due to our consolidation and redevelopment of several data centers since the second quarter of 2023. Adjusted EBITDA was CNY 539.8 million with adjusted EBITDA margin of 28.4%. Net loss attributable of VNET was CNY 187 million.
Turning to our balance sheet. At the end of first quarter, the total amount of the company's cash and cash equivalents, restricted cash was CNY 2.1 billion. Meanwhile, net cash generated from operating achieved was CNY 267.6 million. Our CapEx was CNY 971.3 million.
For updates on our financing, as we mentioned last quarter, on February 1, 2024, we completed the repurchase payments relating to our convertible senior notes due 2026 in the total principal amount of USD 600 million. In the current capital market environment, this strategic move reflects our resilient business fundamentals and our commitment to long-term sustainable development.
Now moving to our full year guidance for 2024, we expect net revenue to be in the range of CNY 7.8 billion to CNY 8 billion, representing a year-over-year increase of 5.2% to 7.9% and adjusted EBITDA to be in the range of CNY 2.22 billion to CNY 2.28 billion, representing a year-over-year increase of 8.9% to 11.8%. This unchanged from our previous guidance.
Given the last market conditions, we have increased our delivered plan to 100 to 140 megawatts from previously stated 100 to 120 megawatts. CapEx is expected to be in the range of CNY 3.7 billion to CNY 4.2 billion. This is unchanged from our previous guidance and may further increase according to market conditions.
Looking ahead, our focus which remain on high-quality growth, we will continue to execute our effective due care strategy and further enhance our core capabilities to capture market opportunities driven by the AI boom.
This concludes our prepared remarks for today. Operator, we are now ready for questions.
