SHANGHAI and JERSEY CITY, N.J., Sept. 2, 2025 /PRNewswire/ — Shanghai Henlius Biotech, Inc. (2696.HK), and Organon (NYSE: OGN) today announced the US Food and Drug Administration (FDA) has approved BILDYOS^® (denosumab-nxxp) injection 60 mg/mL and BILPREVDA^® (denosumab-nxxp) injection 120 mg/1.7 mL, biosimilars to PROLIA (denosumab) and XGEVA (denosumab), respectively, for all indications of the reference products.^1,2

“The FDA approvals of BILDYOS and BILPREVDA mark a significant step toward expanding access to critical bone care treatments needed by millions of people in the US, including a growing aging population.^3,4,5 Our goal with these biosimilars is to improve access and affordability across multiple therapeutic areas, including for osteoporosis, which disproportionately affects women,” said Jon Martin, US Commercial Lead, Biosimilars and General Medicines at Organon.^3,4 “This approval underscores Organon’s unwavering commitment to making treatments more accessible while focusing on creating a more sustainable future for the care of bone health.”^4,5,6  

BILDYOS is a RANK ligand (RANKL) inhibitor indicated for treatment of postmenopausal women with osteoporosis at high risk for fracture, to increase bone mass in men with osteoporosis at high risk for fracture, for the treatment of glucocorticoid-induced osteoporosis in men and women at high risk for fracture, to increase bone mass in men at risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer, and to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer. See full indications below.

Patients with advanced kidney disease treated with BILDYOS are at greater risk of severe hypocalcemia. Severe hypocalcemia resulting in hospitalization, life-threatening events, and fatal cases have been reported with denosumab products. The presence of chronic kidney disease-mineral bone disorder (CKD-MBD) markedly increases the risk of hypocalcemia. Prior to initiating BILDYOS in patients with advanced chronic kidney disease, evaluate for the presence of CKD-MBD. Treatment with BILDYOS in these patients should be supervised by a healthcare provider with expertise in the diagnosis and management of CKD-MBD. See additional safety information below.

BILPREVDA is a RANK ligand (RANKL) inhibitor indicated for the prevention of skeletal-related events in certain patients with multiple myeloma and bone metastases from solid tumors, giant cell tumor of bone, and hypercalcemia of malignancy. See full indications below.

Hypersensitivity reactions, including anaphylaxis, may occur with use of denosumab products, including BILPREVDA. Discontinue permanently if a clinically significant reaction occurs. Denosumab products can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Correct hypocalcemia prior to initiating BILPREVDA. Monitor calcium levels during therapy, especially in the first weeks of initiating therapy, and adequately supplement all patients with calcium and vitamin D. Osteonecrosis of the jaw (ONJ) has been reported in patients receiving denosumab products. Perform an oral examination prior to starting BILPREVDA. Monitor for symptoms. Avoid invasive dental procedures during treatment. Evaluate patients with thigh or groin pain to rule out a femoral fracture. When BILPREVDA treatment is discontinued, evaluate the individual patient’s risk for vertebral fractures. BILPREVDA can cause fetal harm. Advise females of reproductive potential of potential risk to the fetus and to use effective contraception. See additional safety information below.

“The FDA approvals of BILDYOS and BILPREVDA mark another set of Henlius’ self-developed and self-manufactured biosimilars approved in the United States, underscoring our commitment to scientific excellence and consistent product quality,” said Dr. Jason Zhu, Executive Director and Chief Executive Officer of Henlius. “We’re proud to continue expanding access to quality biologics through the collaboration with Organon, delivering biosimilar treatment options that are as safe and effective as the reference biologics to more patients across the US.”^5,7,8 

BILDYOS and BILPREVDA were approved based on the review of a comprehensive data package, which included structural and functional analytical data, clinical pharmacokinetic data, and a comparative clinical study demonstrating that BILDYOS and BILPREVDA are highly similar to and have no clinically meaningful differences to their reference products, PROLIA and XGEVA, respectively, in terms of safety, purity, and potency.^8,9 

In 2022, Henlius entered into a license and supply agreement with Organon, granting Organon the exclusive commercialization rights to several biosimilars, including BILDYOS and BILPREVDA. The agreement covers exclusive global commercialization rights except for China.¹⁰

“These approvals are a testament to the strong collaboration between Henlius and Organon to expand patient access to quality and potentially more affordable biosimilars,” said Ping Cao, Chief Business Development Officer and Senior Vice President of Henlius.^4,5,8 “Together, we are working to broaden access to important treatment options and better meet the needs of both patients and providers in the US.”⁵

BILDYOS and BILPREVDA join Organon’s biosimilars portfolio in the US, which has been growing for over eight years and spans five major therapeutic areas.^11-14 This milestone reflects Organon’s long-standing commitment to expanding access to quality, cost-effective treatments and to advancing women’s health through a sustainable, patient-centered approach.^5,7,8

SELECTED SAFETY INFORMATION

SEVERE HYPOCALCEMIA IN PATIENTS WITH ADVANCED KIDNEY DISEASE
Patients with advanced chronic kidney disease (eGFR <30mL/min/1.73m²), including dialysis dependent patients, are at greater risk of severe hypocalcemia following denosumab products administration. Severe hypocalcemia resulting in hospitalization, life-threatening events, and fatal cases have been reported.

The presence of chronic kidney disease-mineral bone disorder (CKD-MBD) markedly increases the risk of hypocalcemia in these patients.

Prior to initiating BILDYOS in patients with advanced chronic kidney disease, evaluate for the presence of CKD-MBD. Treatment with BILDYOS in these patients should be supervised by a health care provider with expertise in the diagnosis and management of CKD-MBD.

CONTRAINDICATIONS

BILDYOS is contraindicated in patients with hypocalcemia. Pre-existing hypocalcemia must be corrected prior to initiating BILDYOS. BILDYOS is contraindicated in women who are pregnant and may cause fetal harm when administered to a pregnant woman. In women of reproductive potential, pregnancy testing should be performed prior to initiating treatment with BILDYOS. BILDYOS is contraindicated in patients with a history of systemic hypersensitivity to any component of the product. Reactions have included anaphylaxis, facial swelling, and urticaria.

WARNINGS AND PRECAUTIONS

Severe Hypocalcemia and Mineral Metabolism Changes 
Denosumab products can cause severe hypocalcemia and fatal cases have been reported. Pre-existing hypocalcemia must be corrected prior to initiating therapy with BILDYOS. Adequately supplement all patients with calcium and vitamin D.

In patients without advanced chronic kidney disease who are predisposed to hypocalcemia and disturbances of mineral metabolism (eg, treatment with other calcium lowering drugs), assess serum calcium and mineral levels (phosphorus and magnesium) 10 to 14 days after BILYDOS injection.

Drug Products with Same Active Ingredient
The active ingredient in BILDYOS is denosumab. Patients receiving BILDYOS should not receive other denosumab products concomitantly.

Hypersensitivity
Clinically significant hypersensitivity, including anaphylaxis, has been reported with denosumab products. Symptoms have included hypotension, dyspnea, throat tightness, facial and upper airway edema, pruritus, and urticaria. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue further use of BILDYOS.

Osteonecrosis of the Jaw (ONJ)
ONJ, which can occur spontaneously, is generally associated with tooth extraction and/or local infection with delayed healing. ONJ has been reported in patients receiving denosumab products. A routine oral exam should be performed by the prescriber prior to initiation of BILDYOS. A dental examination with appropriate preventive dentistry is recommended prior to treatment in patients with risk factors for ONJ such as invasive dental procedures (eg, tooth extraction, dental implants, oral surgery), diagnosis of cancer, concomitant therapies (eg, chemotherapy, corticosteroids, angiogenesis inhibitors), poor oral hygiene, and co-morbid disorders (eg, periodontal and/or other pre-existing dental disease, anemia, coagulopathy, infection, ill-fitting dentures). Good oral hygiene practices should be maintained during treatment with BILDYOS. Concomitant administration of drugs associated with ONJ may increase the risk of developing ONJ. The risk of ONJ may increase with duration of exposure to denosumab products.

For patients requiring invasive dental procedures, clinical judgment of the treating physician and/or oral surgeon should guide the management plan of each patient based on individual benefit-risk assessment.

Patients who are suspected of having or who develop ONJ while on BILDYOS should receive care by a dentist or an oral surgeon. Extensive dental surgery to treat ONJ may exacerbate the condition. Discontinuation of BILDYOS should be considered based on individual benefit-risk assessment.

Atypical Subtrochanteric and Diaphyseal Femoral Fractures
Atypical low-energy, or low trauma fractures of the shaft have been reported in patients receiving denosumab products. Causality has not been established as these fractures also occur in osteoporotic patients who have not been treated with antiresorptive agents.

During BILDYOS treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Interruption of BILDYOS therapy should be considered, pending a benefit-risk assessment, on an individual basis.

Multiple Vertebral Fractures (MVF) Following Discontinuation of Treatment
Following discontinuation of denosumab treatment, fracture risk increases, including the risk of multiple vertebral fractures. New vertebral fractures occurred as early as 7 months (on average 19 months) after the last dose of denosumab. Prior vertebral fracture was a predictor of multiple vertebral fractures after denosumab product discontinuation. Evaluate an individual’s benefit-risk before initiating treatment. If BILDYOS treatment is discontinued, patients should be transitioned to an alternative antiresorptive therapy.

Serious Infections
In a clinical trial of over 7800 women with postmenopausal osteoporosis, serious infections leading to hospitalization were reported more frequently in the denosumab group than in the placebo group. Serious skin infections, as well as infections of the abdomen, urinary tract, and ear, were more frequent in patients treated with denosumab products. Endocarditis was also reported more frequently in denosumab-treated patients. The incidence of opportunistic infections and the overall incidence of infections were similar between the treatment groups. Advise patients to seek prompt medical attention if they develop signs or symptoms of severe infection, including cellulitis.

Patients on concomitant immunosuppressant agents or with impaired immune systems may be at increased risk for serious infections. Consider the benefit-risk profile in such patients before treating with BILDYOS. In patients who develop serious infections while on BILDYOS, prescribers should assess the need for continued BILDYOS therapy.

Dermatologic Adverse Reactions
In a clinical trial of over 7800 women with postmenopausal osteoporosis, epidermal and dermal adverse events such as dermatitis, eczema, and rashes occurred at a significantly higher rate with denosumab treatment compared to placebo. Most of these events were not specific to the injection site. Consider discontinuing BILDYOS if severe symptoms develop.

Musculoskeletal Pain
In postmarketing experience, severe and occasionally incapacitating bone, joint, and/or muscle pain has been reported in patients during denosumab treatment. Onset of symptoms varied from one day to several months after starting denosumab products. Consider discontinuing use if severe symptoms develop.

Suppression of Bone Turnover 
In clinical trials in women with postmenopausal osteoporosis, treatment with denosumab resulted in significant suppression of bone remodeling as evidenced by markers of bone turnover and bone histomorphometry. The significance of these findings and the effect of long-term treatment with denosumab products are unknown. Monitor patients for consequences, including ONJ, atypical fractures, and delayed fracture healing.

Hypercalcemia in Pediatric Patients with Osteogenesis Imperfecta 
BILDYOS is not approved for use in pediatric patients. Hypercalcemia has been reported in pediatric patients with osteogenesis imperfecta treated with denosumab products.

ADVERSE REACTIONS

The most common adverse reactions (>5% and more common than placebo) reported with denosumab products in women with postmenopausal osteoporosis are back pain, pain in extremity, musculoskeletal pain, hypercholesterolemia, and cystitis.

The most common adverse reactions (>5% and more common than placebo) reported with denosumab products in men with osteoporosis are back pain, arthralgia, and nasopharyngitis. Pancreatitis has been reported with denosumab products.

The most common adverse reactions (>3% and more common than active-control group) reported with denosumab products in patients with glucocorticoid-induced osteoporosis are back pain, hypertension, bronchitis, and headache.

The most common (per patient incidence ≥10%) adverse reactions reported with denosumab products in patients with bone loss receiving androgen deprivation therapy for prostate cancer or adjuvant aromatase inhibitor therapy for breast cancer are arthralgia and back pain. Pain in extremity and musculoskeletal pain have also been reported in clinical trials.

The most common adverse reactions leading to discontinuation of denosumab products in patients with postmenopausal osteoporosis are back pain and constipation.

Denosumab is a human monoclonal antibody. As with all therapeutic proteins, there is potential for immunogenicity.

Before prescribing BILDYOS, please read the Prescribing Information, including the Boxed Warning about severe hypocalcemia. The Medication Guide also is available.

Please note, BILDYOS is part of the Risk Evaluation and Mitigation Strategy (REMS) program.

About BILPREVDA^® (denosumab-nxxp)

BILPREVDA is a RANK ligand (RANKL) inhibitor indicated for:

• Multiple Myeloma and Bone Metastasis from Solid Tumors: BILPREVDA is indicated for the prevention of skeletal-related events in patients with multiple myeloma and in patients with bone metastases from solid tumors.
• Giant Cell Tumor of Bone: BILPREVDA is indicated for the treatment of adults and skeletally mature adolescents with giant cell tumor of bone that is unresectable or where surgical resection is likely to result in severe morbidity.
• Hypercalcemia of Malignancy: BILPREVDA is indicated for the treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.

SELECTED SAFETY INFORMATION

CONTRAINDICATIONS

Pre-existing hypocalcemia must be corrected prior to initiating therapy with BILPREVDA. BILPREVDA is contraindicated in patients with known clinically significant hypersensitivity to denosumab products.

WARNINGS AND PRECAUTIONS

Drug Products with Same Active Ingredient 
Patients receiving BILPREVDA should not receive other denosumab products concomitantly.

Hypocalcemia
Denosumab products can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Pre-existing hypocalcemia must be corrected prior to initiating BILPREVDA. Monitor calcium levels throughout therapy, especially in the first weeks of initiating therapy, and administer calcium, magnesium, and vitamin D as necessary. Concomitant use of calcimimetics and other drugs that can lower calcium levels may worsen hypocalcemia risk, and serum calcium should be closely monitored. Advise patients to contact a health care provider for symptoms of hypocalcemia.

An increased risk of hypocalcemia has been observed in clinical trials of patients with increasing renal dysfunction, most commonly with severe dysfunction (creatinine clearance less than 30 mL/min and/or on dialysis), and with inadequate/no calcium supplementation. Monitor calcium levels and calcium and vitamin D intake.

Hypersensitivity
BILPREVDA is contraindicated in patients with known clinically significant hypersensitivity to denosumab products, including anaphylaxis. Reactions may include hypotension, dyspnea, upper airway edema, lip swelling, rash, pruritus, and urticaria. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue BILPREVDA therapy permanently.

Osteonecrosis of the Jaw (ONJ)
ONJ has been reported in patients receiving denosumab products, manifesting as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration, or gingival erosion. Persistent pain or slow healing of the mouth or jaw after dental surgery may also be manifestations of ONJ. In clinical trials in patients with cancer, the incidence of ONJ was higher with longer duration of exposure.

A history of tooth extraction, poor oral hygiene, or use of a dental appliance may be predisposing factors to developing ONJ. Other risk factors for the development of ONJ include immunosuppressive therapy, treatment with angiogenesis inhibitors, systemic corticosteroids, diabetes, and gingival infections.

Perform an oral examination and appropriate preventive dentistry prior to the initiation of BILPREVDA and periodically during therapy. Advise patients regarding oral hygiene practices. Avoid invasive dental procedures during treatment with BILPREVDA. Consider temporarily interrupting therapy if an invasive dental procedure must be performed.

Patients who are suspected of having or who develop ONJ while on BILPREVDA should receive care by a dentist or an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition.

Atypical Subtrochanteric and Diaphyseal Femoral Fracture
Atypical femoral fracture has been reported with denosumab products. These fractures can occur anywhere in the femoral shaft from just below the lesser trochanter to above the supracondylar flare and are transverse or short oblique in orientation without evidence of comminution.

Atypical femoral fractures most commonly occur with minimal or no trauma to the affected area. They may be bilateral and many patients report prodromal pain in the affected area, usually presenting as dull, aching thigh pain, weeks to months before a complete fracture occurs. A number of reports note that patients were also receiving treatment with glucocorticoids (eg, prednisone) at the time of fracture. During BILPREVDA treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Patients presenting with an atypical femur fracture should also be assessed for symptoms and signs of fracture in the contralateral limb. Interruption of BILPREVDA therapy should be considered, pending a risk/benefit assessment, on an individual basis.

Hypercalcemia Following Treatment Discontinuation in Patients with Giant Cell Tumor of Bone (GCTB) and in Patients with Growing Skeletons
Clinically significant hypercalcemia requiring hospitalization and complicated by acute renal injury has been reported in denosumab-treated patients with GCTB and in patients with growing skeletons. Hypercalcemia has been reported within the first year after treatment discontinuation. After treatment is discontinued, monitor patients for signs and symptoms of hypercalcemia, assess serum calcium periodically, reevaluate the patients’ calcium and vitamin D supplementation, and treat appropriately.

Multiple Vertebral Fractures (MVF) Following Treatment Discontinuation 
MVF have been reported following discontinuation of treatment with denosumab products. Patients at higher risk for MVF include those with risk factors for or a history of osteoporosis or prior fractures. When BILPREVDA treatment is discontinued, evaluate the individual patient’s risk for vertebral fractures.

Embryo-Fetal Toxicity
Based on data from animal studies and its mechanism of actions, denosumab products can cause fetal harm when administered to a pregnant woman.

Verify the pregnancy status of females of reproductive potential prior to the initiation of BILPREVDA. Advise females of reproductive potential to use effective contraception during therapy, and for at least 5 months after the last dose of BILPREVDA. Advise pregnant women and females of reproductive potential that exposure to BILPREVDA during pregnancy or within 5 months prior to conception can result in fetal harm.

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥25%) in patients with bone metastasis from solid tumors were fatigue/asthenia, hypophosphatemia, and nausea. The most common serious adverse reaction was dyspnea. The most common adverse reactions resulting in discontinuation were osteonecrosis and hypocalcemia.

The most common adverse reactions (incidence ≥10%) in patients with multiple myeloma were diarrhea, nausea, anemia, back pain, thrombocytopenia, peripheral edema, hypocalcemia, upper respiratory tract infection, rash, and headache. The most common serious adverse reaction was pneumonia. The most common adverse reaction resulting in discontinuation was osteonecrosis of the jaw.

The most common adverse reactions (incidence ≥10%) in patients with GCTB were arthralgia, back pain, pain in extremity, fatigue, headache, nausea, nasopharyngitis, musculoskeletal pain, toothache, vomiting, hypophosphatemia, constipation, diarrhea, and cough. The most frequent serious adverse reactions were osteonecrosis of the jaw, bone giant cell tumor, anemia, pneumonia, and back pain. The most common adverse reaction resulting in discontinuation was osteonecrosis of the jaw.

The most common adverse reactions (incidence >20%) in patients with hypercalcemia of malignancy were nausea, dyspnea, decreased appetite, headache, peripheral edema, vomiting, anemia, constipation, and diarrhea.

HONG KONG, Sept. 2, 2025 /PRNewswire/ — The Guiding Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting High-Quality Urban Development (the “Guiding Opinions”) were recently officially released. Driven by this new policy impetus, capital markets have promptly responded with positive signals towards related industries. Among them, Luda Technology Group Limited and its subsidiaries (the “Luda Technology“ or “Company”, NYSE: LUD.US) saw its shares surge more than 15% in a single trading day on August 27, and continued to draw substantial market attention. As a leading enterprise in metal pipe fitting manufacturing and trading, the Company will leverage its core technologies and strategic positioning to fully capitalize on the new development opportunities presented by these policies. Luda Technology remains committed to providing high-quality products and solutions for urban infrastructure upgrades and global pipeline construction projects.

The Guiding Opinions explicitly state that China’s urbanization has transitioned from a period of rapid growth to one of stable development, with urban development entering a new phase focused primarily on improving the quality and efficiency of existing stock. The policy clearly outlines goals to enhance the comprehensive competitiveness of super-large and megacities, promote urban agglomeration integration and metropolitan area coordination in a steady and orderly manner, and support regions like the Beijing–Tianjin–Hebei region, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area in developing into world-class city clusters. Simultaneously, it aims to enhance the capacity of small and medium-sized cities and county towns, improve infrastructure and public service provision, and develop the county economy.

Within this quality-oriented new urban construction cycle, urbanization and infrastructure investment are expected to grow significantly. Particularly, natural gas pipeline projects will drive sustained increases in demand for pipe fittings. Furthermore, the mainland’s push for natural gas power generation to address coal-fired pollution issues has resulted in strong urban gas demand, further stimulating investment in natural gas-related infrastructure. According to market research reports, the global pipeline and pipe fittings market size is projected to reach approximately USD 8 billion by 2025, with an average annual growth rate of nearly 5%.

As a leading enterprise in the metal pipe fittings manufacturing industry and currently the only representative in this sector listed in the U.S., Luda Technology has been dedicated to the R&D, manufacturing, and global trade of metal pipe fittings since its establishment in 2004. With its own factory in Taian, Shandong Province, the Company primarily manufactures and sells stainless steel and carbon steel flanges and pipe fittings, while also trading steel pipes, valves, and other products. The Company has already established close cooperation with numerous petrochemical enterprises and urban pipeline projects, and utilized IPO financing to enhance its technological and R&D capabilities. After over two decades of development, the Company has built four core competitive advantages, positioning it to capture significant industry benefits from this dual policy and market-driven cycle and contribute substantially to global pipeline construction.

Luda Technology ensures exceptional quality and full-process precision control. Since 2008, the Company has introduced internationally advanced CNC machine tools, large gantry milling machines, and a full suite of testing equipment including spectrometers, ultrasonic flaw detectors, and mechanical property testers. This ensures every product leaving the factory fully complies with, and often exceeds, international standards such as ASME, DIN, EN, and JIS, as well as specific customer requirements, in terms of dimensional accuracy, material properties, sealing, and corrosion resistance. This has earned the long-term trust of leading clients in sectors like petrochemicals, electric power, and shipbuilding.

The Company possesses strong customization and flexible manufacturing capabilities. It can rapidly respond to customer-provided drawings or technical parameters to produce non-standard flanges in various specifications from DN15 to DN5000 and above, using diverse materials including carbon steel, stainless steel, alloy steel, duplex steel, and special steel. Through the application of ERP and MES systems, it has achieved digital management from order receipt to product delivery, effectively coordinating production resources and significantly shortening delivery times while guaranteeing quality.

With profound technical expertise and a commitment to continuous innovation, Luda Technology invests substantial funds annually in R&D for new materials, forging process optimization, and heat treatment technology upgrades. It has established industry-academia-research partnerships with several universities and research institutions to tackle industry technical challenges collaboratively, achieving breakthroughs in special products like ultra-low temperature flanges and highly corrosion-resistant flanges. The Company is actively pursuing an intelligent manufacturing transformation, planning to introduce automated robots and Internet of Things (IoT) technology to collect and analyze production data in real-time, continuously optimize process parameters, and enhance production efficiency and product consistency.

Luda Technology operates with a global market vision and provides localized service support. The Company possesses comprehensive export qualifications and extensive international trade experience, with products exported to numerous countries and regions across North America, Europe, the Middle East, and Southeast Asia. By establishing overseas warehouses and service centers, it can provide international customers with more timely and convenient logistics and technical support.

Mr Ma Biu, Chief Executive Officer of Luda Technology, commented, “The release of ‘The Guiding Opinions’ presents us with significant development opportunities. The next five years will be a critical period for high-quality urban development in China, and the pipeline and pipe fittings industry will usher in a new growth cycle. Leveraging the core technological advantages, stringent quality control systems, and rich international trade experience accumulated over the past two decades, Luda Technology is fully prepared to seize this market opportunity. We will continue to increase R&D investment, deepen our intelligent manufacturing transformation, provide global customers with higher quality products and services, and contribute to high-quality urban development.”
